] | Purpose: The aim of this study was to determine the reliability and accuracy of measurements in digital models(CEREC AC) compared to stone models.
Methods: A master model(500B-1, Nissin Dental Product, Japan) with the prepared upper full arch tooth was used. Conventional impression and then stone model(n=10) were produced from this master model, and on the other hands, digital impressions were made with the CEREC AC intra-oral scanner(n=10). One examiner measured two times the intercanine, intermolar distance, dental arch length. The stone model were measured using a digital caliper. The t-student test for paired samples and intraclass correlation coefficient(ICC) were used for statistical analysis.
Results: The measurement of two methods showed very good reliability. At the intra-examiner reliability of measurement, ICC at the stone and CEREC AC model were 0.81 and 0.94. The mean difference between measurements made directly on the stone models and those made on the CEREC AC model was 0.20~0.28 ,and was statistically significant(P=0.001).
Conclusion: These in vitro studies show that accuracy of the digital impression is similar to that of the conventional impression. These results will have to be confirmed in further clinical studies. | 치의학 | null | http://dx.doi.org/ | kci_detailed_000200.xml | ||

] | Purpose: This study conducted a survey on the elderly of 65 years and over with physical debilities and ones capable of living at home residing in Jeju Special Self-Government Province to compare and analyze demosociological characteristics and factors influencing on oral health related living quality. And also this study intended to provide basic data for developing effective public medical policies and health promotion programs to increase oral health related living quality of the elder.
Methods: The elderly of 65 years and over living in Jeju Special Self-Government Province were interviewed individually from 7 February 2011 to 18 April and interview results of a total of 220 subjects were analysed for this study.
Results: Current status of the elderly including ones with & without physical debilities influenced functional limitation and behavioral aspects of GOHAI criteria used in this study. The eldely with physical debilities experienced less limitaion in food chewing and swallowing, and pronunciation than ones capable of living at home.
On the analogy of the previous study(by Park, N. G., 2010) in which oral health related quality and satisfaction of life of the elderly with physical debilities were different due to their physical, circumstantial and psychological limitations, the former's oral health conditions are worse than the ones capable of living at home and because of medical care accessability limitation they suffer from deteriorated oral condition.
By the comparison of factors influencing on the living quality relating to the oral health of the elderly with physical debilities and ones capable of living at home, 2 factors, age and living area, were meaningful factors commonly influencing on the oral health related living qualities of both. The elderly of 75 years and over were more affected by psychological and behavioral aspects of oral health related living quality than the ones of 65-74 years,and the ones living in country suffered from functional limitations, pains and discomfort more than ones in city.
Additionally, being different from the elderly capable of living at home, the ones with physical debilities were influenced by the factors of average monthly income and medical security type.
Conclusion: Improvement of programs and systems to increase oral health related quality of life needs to be carried out preferentially for the elderly of 75 years and over, and dwelling in country. Also this study suggests that the policy of paying the denture insurance allowance in 2012 need effective planning considering the elderly’s current status, age, living area, medical security type. | 치의학 | null | kci_detailed_000200.xml | |||

Methods: Random selection was made on old men living in Daejeon and Chungnam, and a survey was conducted from April 15 to May 20, 2011. 500 questionnaires were distributed and 420 questionnaires were collected. Using spss 18.0 program, final analysis was made on 363 questionnaires except for 57 questionnaires which had missing value or showed some doubts about the unreliability.
Results: 1. With respect to number of natural teeth as per the age, the upper/lower jaws had meaningful differences (P<.001), which means that the older the person is, the smaller number of natural teeth is. In the meantime, there was no meaningful difference according to sex. 2. With respect to kind of prosthetics installed in a mouth as per the age, there was meaningful difference in the upper jaws (P<.05) but there was no meaningful difference in the lower jaws. It was found out that the older the persons are, the more they use removable dentures while the younger the persons are, the more they use fixed partial dentures. 3. With respect to mouth health condition recognized by oneself, it showed bad (44.4%) and good (10.3%),which means recognition as bad is greater, and the age when prosthetics were first used is dispersed variously from below 40 to over 70. 4. Dental care institutions which they mainly used are hospital and clinics (91.5%), and 66.4% of them visited dental clinics lately.
Preferential treatment if they go to dentists is as follows in the order of prosthetics (33.9%), gum treatment (24.2%)and pain treatment (14.9%). 5. 68.4% of them revisited dentists after installation of dentures and the reason for revisit is as follows in the order of poorly fitted dentures (35.1%), painful gum 25.9%, regular check-up 25.4% and difficult chewing 9.6%.
Conclusion: As our country enters into an aging society, mouth health problem of old men has come to a serious issue, and therefore, a survey was conducted on some old men with respect to their utilization status of dental clinic and removable dentures in order to provide basic data for improvement of quality of their life, maintenance and enhancement of their mouth health. The study result shows that the older they are, the higher the loss rate of teeth as well as needs for prosthetics are, and thus it is thought the study will help to develop mouth health education program which may improve quality of old men’s life by recovery of mouth functions declined due to loss of teeth and by regular check-up, education for mouth health control and following-up control of dentures. | 치의학 | null | kci_detailed_000200.xml | |||

Methods: A total of 240 dental technician who are registered with the Daegu Association of Dental technician and working at 34 dental laboratories participated in the study. And the dust level was measured at 21 different spots in 16 dental laboratories out of 34.
Results: Of 34 dental laboratories, 31 (91.2%) were equipped with a ventilator, but the remaining 3 (8.8%) did not have a ventilator. By the number of ventilator, 1 to 3 ventilators were found in 22 dental laboratories (71.0%), 4to 6 ventilators were in 7 laboratories (22.5%) and more than 7 ventilators in 2 laboratories(6.5%). According to the frequence of changing filters in dust collector, 20 dental laboratories (58.9%) changed filters every four weeks,10 laboratories (29.4%) changed them every six weeks and 4 laboratories (11.7%) changed them every eight weeks.
Of total respondents, 114 (61.3%) said they wore a mask all the time while working, 56 (29.6%) said they frequently wore a mask, 19 (10.1%) said they did not wear a mask. As for the type of masks, 159 (84.1%) used a disposable mask, 25 (13.2%) used a cotton mask and 5 (2.7%) used an anti-dust mask. For dust sat on their outfits while working, 102 (54.0%) shook their uniforms inside workplace to keep dust off the uniforms, 64 (33.9%) did not anything until they wash their uniforms and 23 (12.1%) shook their uniforms outside workplace to keep dust off the uniforms. Of total respondents, 182 (96.3%) had a particle in their eyes while carrying out grinding work.
Based on the measurement of floating dust at workplace, 3 dental laboratories showed dust concentration exceeding the minimum level of 10 / allowed under the permit for environment. Of those, 1 laboratory had the dust concentration that was more than 1.5 times higher than the minimum level.
Dust concentration was higher in laboratories that used a dust collector with 0.5 horse power and changed filters more than 3 weeks ago.
Dust comprised of nickel (more than 70%), chrome (9%) and others. The mean chrome concentration was more than twice higher than the minimum permissible level of 0.5 / . There were two laboratories that showed chrome concentration exceeding the level of 0.4 / . Like dust concentration, chrome level was higher in laboratories that used a dust collector with 0.5 horse power and changed filters more than 3 weeks ago. There were six laboratories that had nickel concentration exceeding the minimum permissible level of 1 / . Of those, one laboratory had nickel concentration that was more than three times higher than the minimum permissible level.
Nickel concentration was also higher in laboratories that used a dust collector with 0.5 horse power and changed filters more than 3 weeks ago.
Conclusion: It is not likely that heavy metal concentrations found in the study constitute respiratory dust. It is however necessary for health of dental technician to apply the Industrial Safety and Healthy Law to dental laboratories and make recommendations for the use of personal protective equipment, installation of a proper number of ventilators, more frequent change of filters in dust collector and improved ventilation for polishing work.
At the same time, dental technician need education on how to use personal protective equipment and how to efficiently remove dust from their uniforms. | 치의학 | null | kci_detailed_000200.xml | |||

] | Purpose: The purposes of this study were to provide information about safe actions during the practice of dental technology, promote belief in safe actions among the students of dental technology, and reinforce their knowledge about how to act safety.
Methods: Open questions were asked to 120 sophomores majoring dental technology to understand the target group’s belief about safe actions. Following the instructions by Ajzen & Fishbein, the collected data were grouped according to similar beliefs. Those beliefs of the highest frequency were given a priority and got to represent the belief level of the target group. Even with belief changes, however, they would not be able to practice safe actions if they had no knowledge about how to do safe actions. For desirable behavioral changes among the students, the students were then asked to discuss the current state of safety accidents and issues focusing on the materials and processes used in the practice and give presentations regarding the subjects to identify risk factors. Then the identified risk factors were used to devise the program contents so that the students could practice safe actions through accurate behavioral approaches and belief changes by educating them about how to act safely by the practice processes and the involved materials and devices.
Results: Not only do the students of Dept. of Dental Technicians have difficulties with the complex practice processes while practicing to make dental prosthesis, but they are exposed to the risk of accidents as they’re poor at dealing with the materials and devices. Although there is a definite need for accident prevention education programs before practice, the reality is that the school doesn’tthe schoosuch education. Based on the judgment that an education program designed to reinforce belief for behavioral changes would generate effgrams results, an education program was developed by applying the Theory of Planned Behavior(TPB). Along with their beliefs, the current state of accidents n. Basepractice, demand for safety education, and practice level of safe actions were used to device the contents of accident prevention education and to develop an accident prevention education program for dental technology.
Conclusion: The study presents an accident prevention education program developed to reinforce dental technology students' beliefs and knowledge and to help them do safe actions during practice. | 치의학 | null | kci_detailed_000200.xml | |||

] | Purpose: To investigate shear bonding strength between dental zirconia ceramics with different surface treatment and metal bracket.
Methods: Zirconia ceramics(LAVA, 3M ESPE, USA) were divided to 4 groups according to their surface treatment; no surface treatment(G1), sand blasting(G2), silane coating(G3), and sand blasting+silane coating(G4).
Specimens were bonded to metal bracket using resin bond(TransbondTMXT, 3M Unitek, USA). Shear bond strength was measured using universal test machine(3366 INSTRON. U.S.A) with cross head speed of 1 mm/min.
Microstructural investigation for fracture surface was performed after shear test.
Results: Shear bonding strengths of single surface treatment groups (G2 and G3) were higher than no treatment group(G1). Combined Treatment Group (G4) showed the highest shear bond strength of 9.15 . Microstructural observation shows that higher shear bonding strength was obtained when debonding was occurred at metal bracket/resin interface rather than zirconia ceramic/resin interface.
Conclusion: Surface treatment of zirconia is necessary to obtain higher bonding strength. Combined treatment can be more effective when surface the surfaces are kept clean and homogeneous. | 치의학 | null | kci_detailed_000200.xml | |||

Methods: Twenty-two elderly care facilities within Jeju Special Self-Government Province participated in the survey. Between 11 January and 5 March 2010, a total of 250 elderly persons(65 and over) with physical debilities were interviewed and their dental health was checked.
Results: The results of the survey are as follows. The need for social support for dental care of the elderly with physical debilities was high in the medical institution-supported service (49.6%). The unmet needs for physical care were high in bathing (49.6%) and using public transportation (71.6%). More than half of these surveyed had ten or fewer teeth. The survey found that 31.6% of the participants experienced problems eating, due to poor dental health. Concerning quality of life, 30.5% of those surveyed experienced physical pain.
Conclusion: In summary, the ages of the survey participants directly relates to the degree of behavioral debility experienced. The more debility a participant exhibits, the greater is the need for social support and dental care. The dental health of a participant directly relates to a higher quality of life. Good dental health of a participant translate to better quality of life. In light of the fact that the elderly with physical debilities suffer from a lack of accessibility to medical care and worse oral health than do other elderly persons, it is essential to increase accessibility to medical institutions that can provide such services as door to door dental care. Current insurance policies, funding for denture insurance, and free denture and denture-upgrade programs desperately need to be expanded.
Therefore, to improve effectively the quality of life for the elderly with physical debilities civil dental medical resources should be encouraged to provide inclusive and prevention-focused medical care. In the public domain door to door dental care services and cooperation with civil dental care resources need to be improved to increase impartial accessibility to dental medical institutions | 치의학 | null | kci_detailed_000200.xml | |||

Methods: The Schmitz-Schulmeyer test method was used to evaluate the core-veneer shear bond strength of zirconia core ceramic(IPS e.max ZirCAD ) and their manufacture recommended two veneering ceramic systems(IPS e.max ceram , IPS e.max ZirPress ). A metal ceramic system(Bellabond plus , VITA VM13 )was used as a control group for the two all ceramic system test groups. The maximum loading and shear bond strength was measured. The average shear strength( ) was analyzed with the one-way ANOVA and the Tukey’s test( =.05). The fracture specimens were examined using Microscope to determine the failure pattern.
Results: The mean shear bond strengths(SD) in MPa were MBSB control 43.62(2.13); ZBSB 18.65(1.76); ZPSB 18.89(1.54). The shear strengths of the zirconia cores were not significantly different(P>.05). Microscope examination showed that zirconia specimens presented mixed failure, and base metal alloy specimens showed adhesive failure.
Conclusion: There was no siginificant different between the layering technique and the heat pressing technique in the veneering methods on the zirconia cores. None of the zirconia core and veneering ceramics could attain the high bond strength values of the metal ceramic combination. | 치의학 | null | kci_detailed_000200.xml | |||

By the repetitive firing, the hardness of the tested alloy decreased gradually. By holding the specimen at 500 for 10-20min after simulated firing, the hardness increased apparently.
However, to hold the alloy for long periods of time in the relatively high temperature after simulated firing resulted in the formation of thick oxidation layer. The oxide film formed on the surface of the alloy after simulated complete firing with controlled cooling rate, which was mainly composed of O and Zn.
Conclusion: It is reasonable to hold the alloy at 500 for 10-20min after complete firing in other to improve the final hardness of the alloy | 치의학 | null | kci_detailed_000200.xml | |||

] | Purpose: The grindability of binary Ti-X%Zr(X=10,20,40) alloys in order to develop a Ti alloy with better machinability than unalloyed titanium has been evaluated.
Methods: Experimental Ti-Zr alloys were made in an argon-arc melting furnace. Slabs of experimental alloys were ground using a SiC abrasive wheel on an electric handpiece at circumferential speeds(12000,18000,25000 or 30000rpm) by applying a force(200gr). Grinding rate was evaluated by measuring the amount of metal volume removed after grinding for 1 minute and the volume ratio of metal removed compared to the wheel material lost,which was calculated from the diameter loss (grinding ratio). Experimental datas were compared to those for cp Ti(commercially pure titanium) and Ti-6%Al-4%V alloy were used controls.
Results: It was observed that the grindability of Ti-Zr alloys increased with an increase in the Zr concentration.
More, they are higher than cp Ti, particularly the Ti-20%Zr alloy exhibited the highest grindability at all circumferential speeds. There was significant difference in the grinding rate and grinding ratio between Ti-20%Zr alloy and cp Ti at any speed(p<0.05).
Conclusion: By alloying with Zr, the Ti exhibited better grindability at all circumferential speeds. the Ti-20%Zr alloy has a great potential for use as a dental machining alloy. | 치의학 | null | kci_detailed_000200.xml | |||

There is no exception to this in the field of construction. Modern construction, however, has caused environmental destruction and pollution, disturbing the coexistence of humans and nature. Therefore, this thesis aims to explore how humans and nature can maintain a mutually beneficial relationship by looking into the construction of Jeju’s traditional dwelling house. This thesis examines the geographical features of Jeju and looks into how Jeju people have adapted themselves to nature. It is assumed that geographical features have created Jeju’s unique environment and style of architecture and differentiated Jeju’s traditional houses from those of other regions. Also, it is considered that geographical features had a large impact on traditional construction such as the floor plan and the layout of buildings. Accordingly, this thesis explores the way traditional houses protected house dwellers from the natural environment and examines the wisdom of our ancestors who took advantage of the natural environment. In addition, this thesis aims to contribute to creating Jeju’s unique construction culture and environment by studying materials, structures, and forms that were applied to the traditional houses of Jeju. | 건축공학 | null | http://dx.doi.org/10.14577/kirua.2014.16.2.35 | kci_detailed_000200.xml | ||

] | Cities of China have been expanding rapidly during the last 10 years and the living environment of urban population developed highly making little difference with the developed nations. However, in the case of rural area, situation is totally different from the urban area. There are some cases where the quality of life in rural areas is retreating compared to the past. Agrarian cultures of the past are remained in the rural area with only older generations and no younger generations. The difference between the rural and the urban and the movement to the cities are increasing in a rapid speed. This led to the recognition of potential danger that lies on the agricultural societies which can demolish the economic development’s sustainability.
Therefore, in this study, basic information about the current Chinese elderly’s house circumstances and to build new houses suited for the older generations will be provided. This can not only enhance the quality of the elder citizen’s life, but also can be a meaningful research for the ideal construction of future Chinese agriculture. | 건축공학 | null | http://dx.doi.org/10.14577/kirua.2014.16.2.55 | kci_detailed_000200.xml | ||

Tourists who visit more than four times to Marado evaluated low in satisfaction for landscape of Marado but tourists who reside in other area not Jeju evaluate higher in satisfaction for landscape. The difference of residence areas shows same result in tourism attraction factors. Tourists participating in tour activities show higher in satisfaction rather than no-participants but the difference between participants and no-participants is not showed in tourism attraction factors. Tourism attraction is extracted four factors; natural environment, architectural environment, economic efficiency and psychological factor. The factors of natural environment and architectural environment have the relation with satisfaction but the factors of economic efficiency and psychology do not show no relation with satisfaction. | 건축공학 | null | http://dx.doi.org/10.14577/kirua.2014.16.2.45 | kci_detailed_000200.xml | ||

] | In the past, Korea was classified as a region not affected by earthquakes. However, recent increase of earthquakes has forced to strengthen standards of earthquake resistant designs of structures to minimize seismic damage. In addition, it was thought that masonry infill walls in buildings are only acting as partitions, so these walls are not considered in analyzing building structures. But it was found that when seismic loads are applied to a structure with masonry infill walls, the walls affect the structure. Accordingly, this study conducted nonlinear static analyses for a structure constructed before applying earthquake resistant designs in two cases: when considering masonry walls and when not. The result showed that the seismic performance of the structure is insufficient. Thus, the structural resistance of the structure was also studied in two cases: when reinforcing with steel plate braces and when using carbon fiber braces. In the two cases reinforcing two different stiffeners, it was appeared that the behaviors of the structure were similar, though the cross-section area of a carbon fiber brace used to reinforcing the structure is only 12.6% of a steel plate brace, and its weight is only 2.8%. Thus, the reinforcing effect of the thin, light-weighted carbon fiber brace is much larger than that of the steel plate brace, when considering usability and constructability of both materials. | 건축공학 | null | http://dx.doi.org/10.14577/kirua.2014.16.2.1 | kci_detailed_000200.xml | ||

Most of them are not kept with houses in traditional village and the other structures in garden area of Korea, because they are located in the isolated field or placed near along the local street, are designed as a very heavily designed building, and are covered by different materials and color against village architecture. I researched cattle barns in both Korea and Germany of what they have had images in a distance-view points of local area, so that I might find a suitable image of Barn Architecture with topography of rural areas. I surveyed rural agricultural buildings with different point of views on landscape structure, architectural form and materials, and conditions animal welfare.
There are three results from this paper as follows: First, the placement of animal barn in garden area is isolated to village so that it may keep a clean environment of village, which it makes non appropriate to land using and village view. Second, the architectural form makes a different image to the village building, because it has an oversize against houses in village or has no rhythm and dividing form of simple gable barm. Third, the barn architecture is better to consider of eco-friendly materials with animal welfare concept design, when it starts to design the barn in the field. | 건축공학 | null | http://dx.doi.org/10.14577/kirua.2016.18.2.55 | kci_detailed_000200.xml | ||

And the modification principle and method of spatial system is proposed as follows; The basic principle of the spatial system modification is to respect the traditional hierarchy in village roads, between the main road and sub-roads, and the territoriality of settlement space that is typically differentiated as the social, individual, and ceremonial domains, from the front to rear part of settlement. With this principle, it is recommended to restrict the tour route to one that is composed of the main road and the periphery road of housing area, and some connecting sub-roads. based on the surveyed tourists’s routes. And it is suggested that the tourist facilities, whether they are existing houses or newly built buildings, and the tourist programs are necessary for experience tourism to cultural property villages, and they are proposed to be placed along the restricted tour route. | 건축공학 | null | http://dx.doi.org/10.14577/kirua.2016.18.2.47 | kci_detailed_000200.xml | ||

This draws the conclusion by analyzing the field survey about residence of the Han Chinese and the Korean-Chinese in Yanbian Area of China. First of all, the characteristic of residence style change and the plan of rural houses of the Han Chinese are in the following. The plan of houses has been changed from allocating rooms from side to side with the kitchen as the center to linking each functional spaces through the aisle. And the main bedroom of houses becomes the central space for family members instead of Kang (partial Ondol) by expanding the floor heating system under the whole floor in houses. Next, the feature of residence style changes of the Han Chinese and the Korean-Chinese is as follows. In 1970s barns disappeared from houses of the Korean Chinese, but houses of the Han Chinese were not much changed. From 1980s to 1990s, spaces linking each rooms with aisles had appeared for comfortableness of residence and respecting each individual's privacy. On the other hand, The houses of the Korean-Chinese make a whole big space by getting rid of walls between the rooms. And after 2 thousand years later, Han Chinese houses have a bedroom with floor heating system. Both houses of the Korean-Chinese and the Han Chinese are changed to have a residence style which taking sedentary style and standing style. | 건축공학 | null | http://dx.doi.org/10.14577/kirua.2016.18.2.29 | kci_detailed_000200.xml | ||

Six representative contemporary earth architects were selected, and then their works were analyzed. Themes of vernacular architecture based of Frampton's critical regionalism were emerged. Findings were as following: 1) constructed by considering the local climate and the region's natural characteristics, 2) constructed with local materials seeking integration of structure and finishing work, 3) having tectonic form included regional characteristics, 4) creating space of various senses and expression of texture through earth modeling, 5) presenting homogeneity of sense of place between site and architecture, and 6) pursuing ecological and sustainable architecture. These characteristics of contemporary earth architecture reflect the vernacular architecture inherited continually in architectural history.

Nevertheless China was changed socialism system, rarely floor plans were influenced by the system during this period. From 1960s to 1970s, the livestock and rural mechanization are influenced by the “People’s Commune” policy. The “Barn” and “Mill” were converted into “warehouse”. The residential part consists of one Jeongji (space mixed dinning and kitchen) and one to three of Ondolbang (room). From 1980s to 1990s influenced by the policies of “Cultural Revolution”, “Birth Control” and “Chinese Economic Reform”, the Korean traditional customs like “elders first” and “distinction between the male and female have been gradually vanished.

Cheongju castle had been completely destroyed In 1915, and urban structures been also altered last 100 years from 2015 now. Periodically, after destruction of castle, existing roads were extended and transformed to straight line for connecting with around. Expanding urban area to all directions of castle boundary in 1930-40s, town planning were created. These projects were completed in 1960-70s, the street network was built as they are. Since the 1980s, changes had been occurred in the details such as an extension of the unexecuted roads, the opening of fire lane in a block, and etc.
In change and construction of roads, urban district plan in 1939 and reorganization since 1967 were planned and established with the type, location, and width of the large, medium and small roads based on data before destruction of castle. Except the width of 25m Sajikro(large3-1) and Sangdangro(large3-8,9,10), the width of 15m Namsaro(medium2-1) and Namjuro (medium2-4) as an extension of the roads, the other roads were small roads equivalent to the existing roads, and so remain intact figure of streetscape.
As such, roads of east-west and north-south cross type, roads showing the outline of Cheongju castle fortress, and alleys outside the south gate are sustained in Seongan-dong of cheongju as historic urban area, and also present roads are delicately executed to the existing urban fabric. | 건축공학 | null | kci_detailed_000201.xml | |||

Such housing polices have resulted in urban sprawl in the metropolitan areas, and a growing polarization between urban and rural areas. In addition, the issue of “dehumanization” has emerged as a result of the interchangeable urban landscapes and the growing number of high-rise residential buildings. In short, the residential communities of the past, such as towns and villages, have disappeared and been replaced with societies that value individuality and anonymity.

Based on size computation elements such as the number of passengers of cruise ships with the largest size of port entry, ship landing rate, passenger processing ratio, and surge factor, the CIQ facility size for each service level grade was reviewed. As a result, the area of 2,971m2 (A grade), 2,409 m2 (B grade), and 2,088 m2 (C grade) were computed. This showed that the area of B grade was about 82% and C grade 70% compared to the area of A grade. The CIQ facility size computed for each service level grade in this research was analyzed that its area needed to be increased by 322% at least and 458% at most, compared to the CIQ facility area of 649m2 of the existing design (2010). In order to respond to the increasing number of cruise passengers, provide high-level passenger service, and improve the international image of Jeju, Seogwipo cruise terminal should secure the size that is equal to or higher than the B grade of service level. | 건축공학 | null | kci_detailed_000201.xml | |||

And these counties have organized the complex on a large scale among the rental housing. Local governments have managed and operated directly, also these governments have two different methods for the co-management, and the way of making payment. Rental housing management services are divided into rental management, housing management, tenant management. Rental management services such as residents of recruitment, tenants and retreat, rent collection and the storage, management and leasing promotion of the cantilever, surveys of residents. Housing management services such as check of various facilities, maintenance and maintenance work, security and cleaning and daily facility management. Tenant management is life management in connection with housing welfare. In the rural type of rental housing, there are few cases to operate a management office. It is often supplied by rental housing to buy a house or vacant land within the existing village. In this case, by utilizing community facilities within the existing village instead of establishment of extra facilities,It doesn't need to make payment for maintenance fee. In the smaller complex than No. 20, it is self-managed by the tenants in order to reduce the administrative costs and specify the necessary municipal manager. Organization form can be maneged directly from local governments and part of for the management of the building can be employed a mixed management system to delegate management to private organizations such as non-profit organizations or neighborhood association.

] | 10 years ago, in Sijeon-ri, Dogo-myeon, Asan-si, the existing stream was repaired to develope Mt. Dogo trail and irrigation systems through road expansion pavement construction and small stream repair construction. The trees such as persimmon and willow are eliminated that rowed on both sides of the stream and dredging work to dig the rock and sand have been performed. As a result, wide asphalt road was built, also flood damage worries were reduced. 10 years passed and now, how did local residents think about the stream repaired before and after? Village residents, public officials, and the stream construction engineer were interviewed. Villagers indicated a problems that brook became a place where water peppers were taking over and water was stagnating due to the slow velocity so nothing could live and natural landscape like a wash place and the cascade disappeared, because rock and sand were taken out brought soil into the brook. Public officials and engineers were aware of the problems at the time of the stream.
Now that construction is completed after 10 years, Both realistically and budgetary to restoration would be difficult. However, it is necessary to seek for waterfront space which can be restored or replaced by a part of the stream like similarly before. In addition, it is necessary to restore to the progression of a natural stream which connect with stairs(or slope) - small waterfalls - pools - wash place.
In this paper, we hope to take a lesson from the Sijeon-ri model and make rural stream construction be prepared with consideration about not only distinct characteristics of specific area but also the opinion of local resident. | 건축공학 | null | kci_detailed_000201.xml | |||
