The increasing number of vehicles owned by individuals in association with the rising income resulted in an acute shortage of parking spaces. We are not only seeing a serious traffic congestion arising from the vehicles parked in the streets adjacent to apartment buildings, but also the social issues of not being able to properly prepare for the emergency such as breakout of fires. Although remodeling of old apartment buildings are being discussed in measures to these problems, the research of parking space expansion is still insufficient. In a survey on remodeling of old apartment buildings, over 30 percent of those who answered cited the parking space as the most needed improvement and said they preferred direct entry as a way to expand parking space among lateral underground expansion methods. The direct entry is a method in which one directly enters the apartment house from the parking lot through the elevator and it requires extended operation of elevators. However, because there are no established systematic processes for elevator extension and works of such kinds are not common, elevator extension works are being done in an inefficient manner. In this research we reanalyzed the processes in order to present the items to be examined for more efficient elevator extension works, and through interviews of experts in the field, we produced the examination items by process from the perspectives of management and technology. This research will be used as a reference material for elevator extension works associated with expanding underground parking lot of apartment buildings.

The elderly rate in South Korea in 2015 is over 13.1%. Especially, the elderly rate in rural area is high. Senior community project in rural that is being promoted by the government. This study's purpose is to provide the reserch group-home for the elderly in Japan rural area. And this paper provided planning of group-home for the elderly in Korea rural area. For this study, respective 5senior housing of Korea and Japan were chosen as respresenting two nations, and every manager was interviewed on housing pattern. This study suggests the planning material as following. First, the effectiveness of the group-home are big. Especially, the elderly was far healthier. Design point is public space(living room, small living room, etc). Maybe, healthy group-home concept is that would be design by Korean traditional housing. Also important public space design is that would be inner courtyard-house, wood floor, Deachong, etc. Two group-homes will construct elderly welfare facilities in between. Otherwise that is need layout of a big public space. In the case of vacant house can used by considering of scale, structure, site condition. Closed school can used through so easy remodeling too. More often than not complex type(hospital, community heath center) was appeared in Japan rural area. In the case of Korea, recommend complex type in community health center and public building. In this case, considering communication, access, contact, group-home keeps on ground floor. In this paper, we hope to take a lesson from group-home planning source for the elderly in Korea rural area.

This study aims to figure out the old people's needs for modification of their housing to maintain an independent lifestyle despite their health status and living arrangements. The total of 438 residents take part in the questionnaire survey research through the quota sampling method grouped by age (60-64 group, 65-69 group, 70-74 group, and over 75 group), sex (male and female), and house type (apartment houses and others). The results are as follows. (1) The old people's most inspired modification needs in interior spaces are remodeling the heating controls in the living room and the bedroom, ventilation facilities and storage spaces in the kitchen, non-slip tile flooring and ventilation facilities in bathroom, an easy door-lock, non-slip tile flooring, a draft cut-off, and storage spaces in the entrance. Besides they require emergency alarm, easy door and window locks, fire and gas alarm, and furniture with easy handling. It is necessary to supply the aged with the appropriate heating controls for their sensitivity to heat, with enough storage spaces for the increased possessions, and with diverse safety systems reflected blunting of mobility and sensibility. (2) As they grow older, the aged require more remote controls and safety facilities such as emergency alarm, easy locks and furniture with distinguishable colors. Male elderly is more concerned with safety, while female elderly do with convenience due to their different time spending in the house. The elderly residents in the apartment houses require the heating controls, a draft cut-off, and storage space less than other types of houses. Thus modification of the heating controls, a draft cut-off, and storage space are regards as basic needs for the elderly residents in non-apartment houses.

Today, more than thiry countries around the world are designated as a mandatory GHG(GreenHouse Gas) emissions country from the UNFCCC(United Nations Framework Convention on Climate Change). Korea is also possible to designate a mandatory GHG emissions country after Second mandatory emissions which will be started in 2013. Accordingly, Korea government has made efforts to reduce GHG and has enforced energy-related policies to deduce building energy. But there is no process such as providing of existing building improvement recommendations or expert verification for building remodeling in Korea energy-related policies compared with policies in other countries. For this reason, improvements of Korea which divided governments and city provinces are suggested. However suggested improvements are directions, so additional research is needed for detail methods.

The purpose of this study is to analyze the cross-sectional ratio of the courtyard, an external space that not only was used as a workplace, shelter, and playground in our lives, but also gave symbolic meaning to Koreans. Since the beginning of 2000, Hanok began to receive rapid attention from people, and Hanok construction and remodeling were actively carried out in urban and rural areas. In particular, Bukchon and Seochon in Seoul, around Cheonmachong in Gyeongju, and Hanok Village in Jeonju became popular places related to hanok, and Gyeongju, Buyeo, Gongju, and Iksan were designated as ancient districts to encourage the construction of hanok. However, although hanok is being built with national trends, support, and interest, attention is focused only on the external form, materials, and convenience of use, and the composition and system of the external space have not been properly reviewed. Therefore, this study aims to understand the functions and meanings of the yard in traditional housing, and to analyze the proportion of the height of the building surrounding the yard and the depth of the yard in terms of closure and opening. In addition, the system and characteristics of the external space of traditional architecture felt by this can be used as basic data in designing traditional architecture.

The purpose of this study is to develop the feasibility of movable partition wall components that are able to correspond changes of structure system and spatial configuration by the needs of residents for the activation of long-life housing. The key element of various movable partition wall components, a movable partition wall, was analyzed for problems through both as-is analysis and field installation in Korea and Japan, and then its feasibility was verified. The movable partition wall can break the uniformity of a fixed one, can integrate and separate limited space by changes in the demands of residents, can be easy to separate, and can be independent. The development of the movable partition wall is important for the realization of diverse residential space, ease of remodeling, environment adaptation, promotion of modularization, etc. It is comprised of surfacing materials, core materials, structural materials, and movable parts. The domestic movable partition wall was verified regarding the feasibility of an apartment house through on-site inspections and sound insulation tests by KOHP21, KICT. In conclusion, the construction of long-life housing that has sustainable values in the use of housing is nationally an important assignment, so as to secure good housing stock.

Methylation of DNA 5-cytosine in mammalian early embryo affects great deal in nuclear reprogramming and chromatin remodeling of developing embryo. Current efforts to clone and produce cloned animals including transgenic animals face various problems including low birth rate, irregular development, and so on. In this report, cDNA for the one of house keeping methyltransfcrase, Dnmt1 was cloned from bovine somatic tissues and was analyzed for its nucleotide sequences to investigate the structure and function of the gene in bovine early development. Nucleotide sequence of bovine Dnmt1 homologue showed 76.8% identity with that of human Dnmtl and 66.4% with mouse Dnmt1. Translated amino acid sequence showed 88.4% homology with human homologue and 75.8% homology with mouse counterpart. Three types of Dnmt1 are reported in mouse and human, and are likely present in bovine tissues. Understanding of role of Dnmt1 in bovine development may shed a light in the field of animal, especially bovine cloning.

This paper deals with a method calculating various hull form parameters which are required in numerical analysis for ship performance such as motion, maneuverability, resistance and propulsion, etc. After the hull form is designed, before the model tests the ship's performances are evaluated by various analysis tools in which the hull form parameters are used with many kinds of forms aside from offset data. Here, The hull form parameters characterize the properties of hull form and contain positional, differential and integral information implicitly. Generally, the commercial CAD-system has not functions enough for supporting these form parameters and therefore each shipyard uses its own in-house analysis program as well as commercial analysis software. To overcome these limitations, modules for supporting these analysis programs have developed. The modules contain cubic composite spline cure using local curve fairing, intersect algorithm, Gaussian integral, and other geometric techniques needed in calculating hull form parameters. Using our analysis-supporting modules, a complex hull form can be remodeled exactly to the hull form designed by CAD-system and any hull form parameter required in various performance analyses can be calculated.

The purpose of this study was to find out the residents' perceptive opinions of apartment housing environment and to contribute to develop a apartment unit plan in Daejeon City. This research was performed by a questionnaire survey method, 464 data was collected from apartment residents lived in about $85m^2$ unit with 3 rooms and the apartments was limited to the complexes within 3 years at Yuseong-gu and Seo-gu. By analyzing those data, findings are as follows: 1) Residents thought living room, kitchen and bathroom were importment space in a unit plan. They needed a storage function in an entrance and a intermediate room, and Anbang(materbed room) so did. L-DK plan type was very preferred. 2) Sub-kitchen was needed for a refrigerator of Kinch, the location of it was realted to a main kitchen and a uitility. the third room was needed for library, home office and storage space. 3) The enlargment remodeling of balcony was showed livingroom balcony or personal bedrooms at the time of occupancy. They needed the balcony near a kitchen or an utility to equip a storage facility. And residents were preferred to their taste rather than a choice of interior concept package services.

This study was designed to understand the residential experience of Korean women living in tropical country. For qualitative research, interviewees were selected by snowball sampling among Korean women living in Malaysia for over 20 years. The selection criteria for interviewees included husband's nationality, occupational experience, future living plan, frequency of travel to Korea. In-depth group and individual interviews were conducted from August 23 to October 7 2014. Subsequently (1) interviewees' general residential experiences in Malaysia were summarized, (2) interviewee's identity and lifestyle with housing pathways approach were clarified, (3) interviewees' residential experiences in 5 issues, reciprocity in residential area, intention of environmental change, meaning of housing and interaction, housing adaptation, and residential satisfaction/dissatisfaction were prescribed and interpreted. In conclusion, the reflection of interviewees' experiences in tropical country, suggested variations of housing structure type within a residential complex, air well and pocket by setback in building block for improving ventilation and noise prevention from neighbors, and ceiling fans in the house were suggested for the upcoming subtropical climate in Korea. Full option and minus options were also suggested for the presale market to reduce before occupancy remodeling needs. The research results implies valuable suggestions for a multicultural society, ecological housing and stronger communities.
