In Seoul, several railway depots are located at the places where a public can easily access. Since a depot occupy a large amount of land itself, it is natural to use those sites for a public building construction such as an apartment complex or a transportation terminal, as an example. Most of the buildings on a depot, however, are exposed to vibration problems, because foundations are excited from the dynamic loading whenever heavy trains pass on the track. Severe vibration may cause a damage to building structures and a troublesome to a community. In this paper, some vibration practices have been examined in order to resolve the vibration problems. First, a critical speed of a train in a railway depot is evaluated. Then, a structural effect on the transmission of a vibration energy has been investigated. Finally, practical approaches to reduce the vibration level have been proposed. In this first half part of the paper, the focus has been on the critical speed and a structural transmission phenomena.

The Seoul Housing Corporation pronounced an alternative design competition and a bidding for Eunpyeong New Town in December of 2004. At first many construction companies were interested in the first New Town Project. But at last a few companies had proposed the alternative design and construction cost. This project needed a conjunction of design ideas and technology know-hows. And the client wanted the brand power of construction company. Ultimately the Corporation hoped that the first New Town Project will end up with high quality successfully. This competition had started with the original construction drawings. Then it needed some alternative ideas and the lowest cost. There were two drawings of non changeable part and changeable part. Non changeable parts are structure like housing unit plan, underground parking lots. Changeable parts are outdoor layout, interior design and building facade. So we tried all ideas of landscape technology and design principles within limited guidelines. The author applied new technology like tilted rooftop greening and sustained container greening on high-rise apartment house. This green technology will be the first trial in Seoul and in the world as well. Daewoo Corporation have accumulated greening technology through the researches by national funding since 2002. Through this New Town Project the green technology will go forward step by step.

The purpose of this research was to find out the housing history of Sakhalin returnees since leaving hometown under the Japanese ruling period. Face to face interview had been done with 20 returnees in the community center during October to December, 2008. Personal life as well as housing histories were differed by the reason to move into Sakhalin, which still influenced the returnee' life in Ansan. The housing they had lived changed from barracks like a training camp, to Japanese small wooden cottage/row house, and then Russian brick house/apartment. Housing alteration and addition were common to renew the old house. The boundary of residing area was mostly limited to the first residing location throughout one's life without a long distance move. Housing satisfaction was very high in Gohyangmaeul because of the improvement of housing facilities and residence itself as well as convenience of housing management compared to the residence in Sakhalin. Economic and emotional aspect of life satisfaction were also high through about 8 years of living in. Forced movers still require the compensation on hand no matter the amount.

The residence plan of Korea has been formed with bias for quantitative growth and uniformity failing at obtaining human value. Also, rapid growth brought about severe problems of deteriorated human life and destruction of environment. The solution for these problems is pursued in many directions, but there is short of active plan yet. The residence shall develop into new direction to satisfy the demand by reflecting society and culture as well as residents. This study examines external design with symbolic representation of regional feature as an alternative for uniform residence environment problem. This study will be a basic data upon suggesting the direction for planning high quality residence environment. This study examined the elements which form external space of residence complex, designed plan for external space of residence complex, and examined how to reflect regional feature which is important element of local community and culture on the space plan for residence complex based on the evaluation by local residents centered on Gimcheon-si, Gyeongbuk which just started local specialty by fostering. 'Special Area for Grape Industry.'

Established redevelopment and reconstruction projects were unified into one law in 2003 when the 'Act of Urban, Residential and Environment Improvement' was enacted. However, the act only focused on the improvement of the physical state of residential environments established by maintenance projects. In order to be effective, the law also needs to improve the nonphysical aspects of the residential environment. While conducting our research and comparing it with past research, we identified the major factors of residential preferences in order to extract and analyze the nonphysical state of residential environments. As a result, we found that social and economic factors are significantly more important to residents than cultural factors. Also, we found that in each district studied the housing preferences were the most important in redevelopment and reconstruction with the exception of Sangdang-Gu (where the community was the most important factor) and Hungduk-Gu (where the social factor was most important). For future purposes, it is necessary to consider the variables according to each location in order to reflect the needs of the residents when building an apartment complex within the redevelopment and reconstruction district.

Recently, in order to prevent increasing energy usages in the international community, many countries have attempted to develop the innovative renewable energy systems. Among the renewable energy systems, Ground source heat pump(GSHP) system which supply the heating, cooling and hot water in the building has been attracted by its stability of heat production and high efficiency. However, the initial drilling costs become very expensive and the construction period takes longer the other systems, because GSHP system needs more than 100 m depth drilling. In this study, in order to reduce initial costs of the GSHP, the building integrated geothermal system using the horizontal heat exchanger was developed. The heating and cooling load in the standard housing model was calculated by a simulation and the system design capacity in the high-rise apartment was decided by the total load. Based on the system design capacity, the high-rise apartments were applied to a BIGS and vertical GSHP system and there are analyzed about initial costs. In the result, the initial cost of BIGS could reduce 24% of the initial cost of the vertical GSHP system.

This study aims to propose a hypothetical urban neighborhood, HanGyo-dong, which is a model for understanding the relationship between the neighborhood change and educational facilities. Three issue layers of the model derived from preceding case studies are: establishment, relocation and redevelopment of educational facilities; formation and redevelopment of adjacent residential areas; and growth of neighborhood commercial cores. The neighborhood changes observed through HanGyo-dong include (1) the formation of educational base and commercial activities along the stream, (2) the growth of student and intellectual community and the installment of public transportation nodes, and (3) the relocation of schools and hospitals followed by a series of redevelopments of single family house into multi-family housing of low-rise residence and high rise apartment complex. The findings call for the collaborative practice of educational administration and neighborhood planning regarding how educational facilities, which were the tool for urban expansion policy, will contribute to the development of the neighborhood's identity as a localized hub.

Objectives: In this study, we conducted an exploratory analysis of the current media trends on schizophrenia using text-mining methods. Methods: First, web-crawling techniques extracted text data from 575 news articles in 10 major newspapers between 2018 and 2019, which were selected by searching "schizophrenia" in the Naver News. We had developed document-term matrix (DTM) and/or term-document matrix (TDM) through pre-processing techniques. Through the use of DTM and TDM, frequency analysis, co-occurrence network analysis, and topic model analysis were conducted. Results: Frequency analysis showed that keywords such as "police," "mental illness," "admission," "patient," "crime," "apartment," "lethal weapon," "treatment," "Jinju," and "residents" were frequently mentioned in news articles on schizophrenia. Within the article text, many of these keywords were highly correlated with the term "schizophrenia" and were also interconnected with each other in the co-occurrence network. The latent Dirichlet allocation model presented 10 topics comprising a combination of keywords: "police-Jinju," "hospital-admission," "research-finding," "care-center," "schizophrenia-symptom," "society-issue," "family-mind," "woman-school," and "disabled-facilities." Conclusion: The results of the present study highlight that in recent years, the media has been reporting violence in patients with schizophrenia, thereby raising an important issue of hospitalization and community management of patients with schizophrenia.

The purpose of this study is to clarify the architectural meaning of the term 'Whole life Department Store' that appeared in newspapers' in the 1980s. A term of 'Whole Life Department Store' is appeared to explain the emergence of department stores, including the space for a wide range of programs and services they need to live, as well as sales. This word, "Whole life", is a compound of the Whole(全) and Life(生活) and word means the entire life. This will assume that you are separated life. So I was thinking that it could be described as regional facilities that classify and distinguish the necessary space for living and building maintenance, etc. in city and architecture since the modern. And Based on this, I would understand the whole life department as regional facilities. Generally a department store is a regional facilities for higher level living area. I analyzed the location and program of department stores at the time of the emergence of the term. Through this analysis department store was located in the daily range around the apartment complex and contained spaces for the daily life of the inhabitants apartment complex. It is significant in this particular department to be valid today and the term of 'Whole Life' department store is not longer used.
