This study aims to identify the characteristics of expression of place identity shown in public design of Choryang Ibagugil in Dong-gu, Busan and analyze them from physical aspects and from psychological ones. Choryang Ibagugil has special historicity indicating that it is a hillside road(Sanbokdoro) dwelling site created after the 6.25 Korean War and the quintessence of Busan. In addition, the site is a good example that used the topographic characteristics as they were and used the road for movement called as 'gil' to design public environment. Ibagugil connected to Sanbokdoro (i.e. Mangyang-ro) starting from the big road (Busan Station) where there was a large floating population represented the regional identity to public design by the medium of 'gil.' As a result of analyzing the characteristics of expression of place identity based on the current status discovered, our conclusions could be drawn as follows: First, place forms identity under interpersonal relationships and there is a story on the lives of people in the contexts between place and identity. Second, place identity is an independent specialty of a certain place and expression of place identity into public design makes the place more place-like. Ibagugil expressed its identity while adapting to the topographic characteristics of hillside road(Sanbokdoro). Third, adjacent public buildings were included into Ibagugil, thus highlighting the placeness, although it is considered that it is ambiguous to determine it as public design in the current-status analysis. Fourth, from the public value aspect, slumized hillside road(Sanbokdoro) was improved, which led to improvement in quality of environment and improvement in pride of local residents. Resultingly, it can be said that the place identity appeared in the public design of Choryang Ibagugil were the stories that happened in this place. Moreover, the indication of future image of how the place will be developed in the future makes the value of the place more significant. Therefore, in public design for expressing place identity, utilization of independent speciality of the site is considered to be an important factor. By doing so, 'place becomes a real place' and 'place can get an independent identity.' Going further, it comes to get the characteristics of 'being the place as it is.'

방사선 비상사고시 예상되는 주민행동특성 조사 및 교통분석을 통해 실제적인 가정에 기초한 울진원전 비상계획구역내 주민들에 대한 소개시간평가를 수행하였다. 본 연구에서 소개시간은 주민통보, 소개준비 및 차량소개시간으로 구성되었다. 소개대상인구는 비상계획구역내 인구밀도 행정구역 및 일시체류인구 등을 고려해 4개의 그룹으로 분류하였다. 주민행동특성 조사를 위해 비상계획구역내 200가구에 대해 설문조사를 실시하였으며, 설문조사에는 가상사고상황을 설명하는 시나리오를 포함하여, 거주지, 소개준비 소요시간, 소개시 교통수단, 대피장소, 소개방향 등에 대한 질의를 포함하였다. 계산된 소개시작 시간분포 및 미시적 교통분석모델인 CORSIM을 이용하여 도로상에서 소개하는 각 차량들의 거동을 모사하였다. 본 연구결과에서 모든 소개대상차량이 비상계획구역 외부로 소개하는 데 있어서는 밤보다는 낮에 소개하는 경우에 더 오랜 시간이 소요되며 반면에 교차로에서의 지체시간은 낮보다는 밤이 더 장시간 지체되는 것을 확인할 수 있었다. 이것은 차량소개 시작분포에 의한 영향에 기인하는 것으로 분석되었다. CORSIM 모델이 비상사고시 나타날 수 있는 혼잡한 교통현상을 적절히 모사할 수 있는 가를 검증하기 위해 오전 출근시간대에 울진원전 주변의 신호등이 없는 교차로에서 Benchmark Test를 수행하였다. 이 시험에서 CORSIM 모델의 예측치는 관찰된 통과차량 수와 잘 일치하여 본 연구목적을 만족시키고 있음을 확인할 수 있었다.

Studies about architectural planning for elderly residences have been carried out to examine various factors including the unit plan, site planning, and size planning. However, no studies have been undertaken that focus on the residents' daily life patterns. This study offers the design guidelines to support the daily life patterns of the elderly through the planning of elderly housing. For this study, elderly residents in Tokyo, Yokohama etc. in Japan were interviewed and surveyed. The results indicate that the changes to the daily life patterns of the residents living in elderly housing are the reduction of household, the increase of free time, and the change of social relationships. The elderly want to utilize their free time and focus on their social relationships. However, the elderly residences that we surveyed pay no consideration to social spaces and programs for their residents except for the cafeteria. To support the daily life patterns of the elderly, elderly housing should set a high value on the location, shared spaces, and unit plans of the residences in order to consider the personal diversity of the residents. Accessibility to public transportation systems and facilities should to be considered in the initial location planning. The revitalization of the public spaces should to be considered during the architectural planning stage. Considerations of personal taste during the unit planning stage are also necessary.

Currently, there is a gradual increase in double-income households in our country, and one-child families gradually become the norm as well due to a decrease in the birth rate. The purpose of this study was to examine the characteristics of spatial use and furniture arrangements in the residential spaces of one-child double-income households in an effort to be of use for spatial planning suitable for their living. 30 cases of double-income households whose children's ages ranged from infancy to secondary school years were visited to have in-depth interviews and make on-site inspections. The findings of the study were as follows: First, the most common spatial use pattern for three bedrooms was using one for the parents, another for their child and the third for personal computers and clothing storage. It signified that the parents and their child used one room respectively, and that there were personal computers and clothing in the third room. Second, as for the pattern of using the rooms according to furniture arrangements, there were great disparities in that regard according to child age. It implies that there were differences in their living and needs for furniture arrangements according to their children's growth. The findings of the study made it possible to determine the state of living in the double-income households in detail, and suggest that differentiated house planning is required depending on children's age groups.

It is currently agreed upon that one of the major challenges in the construction industry is the energy efficiency of existing buildings. The World Meteorological Organisation (WMO) and United Nations (UN) have reported that the concentration of global atmospheric carbon dioxide has increased by an average of 50%, a record speed, from 2015 to 2016. The housing sector contributes to 45% of the UK's carbon emissions. To help tackle some of those issues the recast Energy Performance Building Directive (EBPD) has introduced Nearly Zero Energy Buildings (NZEBs) in the coming years (including buildings that will undergo refurbishment/renovations). This paper will explore the retrofitting of a UK residential dwelling using Thermal Analysis Simulation (TAS, EDSL) software by focusing on building fabric improvements and usage of on-site renewables. The CIBSE Test Reference Year (TRY) weather data has been selected to examine the performance of the building under current and future climate projections. The proposed design variables were finally implemented in the building altogether on TAS. The simulation results showed a reduction in the building's annual energy consumption of $122.64kWh/m^2$ (90.24%). The greatest savings after this were achieved for the annual reduction in carbon emissions and avoided emissions, which were 84.59% and $816.47kg/CO_2$, respectively.

In Scandinavian countries, where the society experienced change of typical nuclear family structure and higher vocational activity rates of married women earlier than East Asian countries, cohousing scheme has been evolved as an alternative housing to reduce housework for working women, and to reduce loneliness of elderly people who stay in their own homes. They can promote active mutual relationship among residents in the community. Korean family structure has been stemmed to more like extended family, but the tendency to live independently from their married children is getting more and more common in new cohort of senior citizens who are active, healthy, economically stable and higher educated. Korea has been industrialized rather rapidly since 1970's and faces to many societal phenomena about quality of life for senior citizens. Introduction of alternative housing solution for these senior citizens is necessary in Korea. In this paper, Danish senior cohousing scheme, particularly, self-work model project is described about its design feature in accordance to site planning, common facility, and dwelling unit. Aiming to mutual support and more frequent social contacts among residents, self-work model cohousing scheme has different design concept from the service mode scheme. Information about design feature of senior cohousing was collected from the published data with drawings and from field survey to 10 exiting projects in Denmark. Of those, 5 projects were described as a case study. It, hopefully, could provide practical information for architectural design when establishment of senior cohousing schemes start in Korea in the near future.

The purpose of this study was to evaluate the effect of the shear bond strength between porcelain laminate veneer and enamel according to the surface treatment and thermocycling. Group I, as a control group, was sandblasted only; group II was sandblasted and etched; group III was sandblasted and silane treated; and group IV was sandblasted, etched and silane treated. A porcelain block was placed onto the etched enamel under a 150g static load and the bonded site was light-cured from 4 directions for 1 minute each. The 72 bonded specimens were stored in water at $37^{\circ}C$ for 1 day. Half of each group were thermocycled at $4^{\circ}C$ and $60^{\circ}C$ for 100 cycles with a dwelling time in each bath of 1 min. Following thermocycling, the specimens were installed in an Instron universal testing machine and the shear bond strength was measured. After the specimens were fractured, the fractured surfaces were examined with SEM. The obtained results were as follows : 1. The shear bond strength of the sandblasted and etched and silane treated group(Group IV) was the strongest of all, and the shear bond strengths between the sandblasted group(Group I) and the sandblasted and silane treated group(Group III) were not statistically different(p>0.05). 2. When the shear bond strength was measured after thermocycling, only the sandblasted, etched and silane treated group(Group IV) was statistically different(p<0.05). 3. The scanning electron microscopic views of the fractured surfaces show more irregularities and more resin fragments in the etched group than in the unetched group. 4. The scanning electron microscopic views of the fractured surfaces show a more delicate surface after thermocycling and after silane treatment than before thermocycling and before silane treatment.
