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.

The purpose of this study was to investigate the residents' use and occupancy-behavior in the activity areas of the senior nursing facilities, and to provide basic information to establish the appropriate physical elements for planning the activity areas. For the study, the observations in five facilities were conducted for one day, from 10 a.m. to 4 p.m by four researchers. The results of the study are summarized as follows: First, most of the using behaviors in the activity areas were the doing nothing or sleeping. The meals and program services were provided in only one activity area of the floor and it showed that the unit care system was perfunctorily conducted at those facilities. In the representative activity area, its openness was the main physical element influencing the spatial using frequency, while the accessibility and the openness in the sub-activity area were most important. The seating arrangements having comers were helpful for residents' interactions. Second, while facility programs and meals were provided in the specific activity area, there was no residents' occupancy in other activity areas at the same time. There were interactions including residents' conversations and watching/observations in non-designated activity areas such as the nursing stations and near corridors. But the residents' interactions and self-regulations were blocked by absence of territoriality, monotonous spatial compositions and furniture arrangements, insecurity of residents' privacy, wide or narrow areas, and isolated spatial type. Based on the results at the above, basic guidelines for planning the activity areas of senior nursing facilities can be proposed as follows: First, the isolated type and the sight interception should be avoided in representative activity areas. It should be partitioned with couple of areas through the appropriate furniture arrangements, and be prepared semi-private spaces in non-designated areas such as nursing station for the interactions among the residents and the staff. Second, in activity areas for small group, the isolated type is not also good for the residents' accessibility. The residents' privacy should be confirmed through the various spatial compositions, and enough areas need to be sure for the diverse furniture arrangements.

This study is intended to understand the styles, colors and color arrangements of costumes expressed on Kisan Kim Jun-geun's genre paintings of Joseon in the late 19th century. The paintings vary according to the status and gender of the person wearing the costume as well as the time period and different situations the person belongs to. Also, this study aims to examine the meaning and value of Kisan's paintings in terms of the history of Korean costumes. The result of this study are as follows: The basic and common attire for people of all status and class is the jeogori(jacket), baji(pants) for men and Banhoijang jeogori, chima(skirt) for women. Men wear Po(coat) that represents their status and age, and they put on various hats according to different weather conditions or work-skill even when in the same status and class. However, women wear the Baeja(vest), Durumagi(coat) and head-dresses when they are cold. Overall, the costume patterns and shapes that appear on Kisan's paintings show the same patterns and structures when compared to different data during the same time period. Thus, they provide useful information to help not only understand the changes of patterns and structures of costumes, but also the situations and emotions of the people of that time period. Moreover, it can be understood that various colors and color arrangements that reflect the situations and emotions of the late 19th century were used. This study that analyses the colors and color arrangements used in Kisan's genre paintings can provide the very basic and systematically arranged data to help understand the unique colors in Korea. These data can also provide important information to understand the use of dyes and pigments during that time. Therefore, Kisan's genre paintings are meaningful and valuable in terms of the history of Korean costumes for these are the data, from which we can review the costumes, colors and color arrangements in the years from 1890 to 1910.

The materials on the development of modern architecture in Korea are being collected and organized in a systemic fashion. However, this is not the case with the materials relative to interior design. They are gradually disappearing or being lost. In particular, no serious attempt has yet been made to determine the characteristics and historic value of the interior design of the modern bank buildings. The purpose of this study is to trace the disappearing legacy of the interior design of modern bank buildings by learning the inner space arrangements of these buildings and the characteristics of modern interior design in order to determine the historic significance of modern commercial interior design. Banks of relatively large scale were selected for the purpose of this study. They consisted of: Chosun Bank(1911) and its Andong, Wonsan and Cheongjin branches; Chosun Shiksan Banks and its Busan, Daegu and Pyongyang branches; the Busan branch of the 18 Bank; Dongil Bank, Chosun Savings Bank(1935) and their branches. The study focused on the space arrangements and design characteristics of these banks. Although they aimed at modernization in designingtheir interior spaces, the modern bank buildings were not representative of any particular style of interior design. While western style designs were prevalent, eclectic designs incorporating many different styles existed. The characteristics of the interior design of banks of the time included installation of such decorations and use of high quality construction materials for interior and exterior expressing the wealth as to create an aura of credibility for the banks, while the floor arrangements were relatively stereotyped and simplified.

본 연구의 목적은 사회적지지, 우울증, 그리고 성인자녀들과의 동거여부 사이의 관계를 조사하기 위해, 뉴욕에 거주하는 만 60세 이상인 한국 이민 노인 175명을 대상으로 면접조사를 실시하고 그 결과를 조사, 분석하였다. 미국에 거주하는 한국 이민 노인들의 가족들과의 별거여부와 우울증간의 관계에 있어서 사회적 지지의 역할을 정확히 이해하기 위해 공변량 구조분석을 이용하여 변인들간의 구조관계를 설명할 수 있는 최적의 이론구조모델이 선정되었다. 자료분석 결과, 미국내 한국 이민 노인들의 우울증 완화에 긍정적 영향을 미치는 사회적 지지의 역할을 설명함에 있어서 가족들과 떨어져 생활하는지의 여부가 한국노인들에게 중요한 역할을 한다는 완충효과 가설(buffering-effect hypothesis)이 직접적 효과 가설(direct-effect hypothesis)보다 더욱 적절한 대안임이 검증되었다. 그러므로, 미국 내 아시아계 이민노인들의 심리적 건강을 증진시키기 위한 사회교육 및 지역사회 참여활동 프로그램이 실질적인 효과를 거둘 수 있도록 해당 성인자녀가족이 함께 참여할 수 있는 서비스를 개발, 확충함은 물론, 높은 우울증세를 보이는 노인들에 대해서는 그들의 어려움을 이해하고 위로, 격려해 줄 대상확보가 중요한 것으로 방안이 제시되었다.

Purpose: The purpose of this study was to investigate the welfare status of nurses and the status of fixed night shifts and flexible work arrangements in both general hospitals and advanced general hospitals in Korea. Methods: A total of 167 hospitals participated in this study, done from April to October 2018. Results: There were 103 hospitals utilizing the fixed night shift system, 22 in the two-shift system, 3 in the fixed holiday shift, 79 in the fixed shift system, and 39 in the short-time working system. The average welfare benefits for nurses increased to 33.02 million won on average. However, welfare services for the nurses were poor: 41.8% of the respondents had a nurses' lounge, 81.7% were given dormitory space at their place of employment, 41.8% had access to welfare facilities, and 56.4% were provided with welfare support countermeasures. Conclusion: The results show an increasing trend of hospitals to utilize fixed night shift and flexible work arrangements. An institutional strategy at the national policy level should be established to implement flexible work arrangements including the fixed night shift system, which has a poor level of welfare.

This paper focuses on examining the effects of span arrangements on displacement responses of plan-symmetric RC frame buildings designed using the direct displacement-based design (DDBD) method by employing non-linear analyses and the skew seismic attack. In order to show the desired performance of DDBD design approach, the force-based design approach is also used to examine the seismic performance of the selected structures. To realize this objective, 8-story buildings with different plans are selected. In addition, the dynamic behavior of the structures is evaluated by selecting 3, 7, and 12-story buildings. In order to perform non-linear analyses, OpenSees software is used for modeling buildings. Results of an experimental model are used to validate the analytical model implemented in OpenSees. The results of non-linear static and non-linear dynamic analyses indicate that changing span arrangements does not affect estimating the responses of structures designed using the DDBD approach, and the results are more or less the same. Next, in order to apply the earthquake in non-principle directions, DDBD structures, designed for one-way performance, are designed again for two-way performance. Time history analyses are performed under a set of artificial acceleration pairs, applied to structures at different angles. It is found that the mean maximum responses of earthquakes at all angles have very good agreement with the design-acceptable limits, while the response of buildings along the height direction has a relatively acceptable and uniform distribution. Meanwhile, changes in the span arrangements did not have a significant effect on displacement responses.

The study has conducted a research on the main shape of domestic multi-family residential buildings. The four arrangements were selected after the research and each of them was analyzed for daylight, view and natural ventilation according to the different pitch of buildings. Based on the results from the analysis, the optimum pitch of buildings for each of the arrangements are as follows. With looking at the outcomes from the analysis on changes in residential environment by the pitch of building buildings in the four arrangements, it was figured out that it would be the best if the distance is more than 1.0H for Case_1. For Case_2, it should be more than 0.9H and for Case_3, it has to be 1.0H or more. Last but not least, it seems to be superb if the distance is more than 0.9H for Case_4.

In this present work, the effect of hole shapes, orientation and hole arrangements on film cooling effectiveness has been carried out. For this work a flat plate has been considered for the computational model. Computational analysis of film cooling effectiveness using different hole shapes with no streamwise inclination has been carried out. Initially, the model with an inclination of $30^{\circ}$ has been verified with the experimental data. The validation results are well in agreement with the results taken from literature. Five different hole shapes viz. Cylindrical, Elliptic, Triangular, Semi-Cylindrical and Semi-Elliptic have been compared and validated over a wide range of blowing ratios. The blowing ratios ranged from 0.67 to 1.67. Later, orientation of holes have also been varied along with the number of rows and hole arrangements in rows. The performance of film cooling scheme has been given in terms of centerline and laterally averaged adiabatic effectiveness. Semi-elliptic hole utilizes half of the mass flow as in other hole shapes and gives nominal values of effectiveness. The triangular hole geometry shows higher values of effectiveness than other hole geometries. But when compared on the basis of effectiveness and coolant mass consumption, Semi-elliptic hole came out to give best results.
