Urban style row-rise houses for rent have been supplied to the center of city from the 1950's first half The amount of stock is about 450,000 houses and occupies about 40％ in the private rented house. As for the structure, the 60％ of them is wooden-structure and the rest is non-wooden. Stocks of 57.5％ of the wooden-structure and 86％ of the non-wooden were built after 1981 years. It was 1981 years that the new earthquake-resistant standard was carried out, the improvement of stocks built before 1981 is necessary because those don't satisfy the present standard. To investigate the renovation possibility of urban style row-rise houses for rent, actual situation of two-story apartment at 2,4, and 5 Chome Taito-Ku in Tokyo was surveyed from July to November 2001. The number of building analyzed is 227 ridges among 234 ridges of the surveyed two-story building. 90％ of building analyzed is wooden structure. 1) The site of 88％ building surveyed is close to a road less than 4m width. It becomes the existing non-conformed building in the building construction act. It is impossible to make a renovation such as rebuilding, extension and remodeling because it requires the set back when renovating this type of non-conformed building, 2) The building built before 1981 is almost wooden-structure, and occupies 37％ of the building surveyed, and doesn't satisfy the present earthquake-resistant standard. An improvement of them is needed because the decrepitude of building proceeds. 3) 50％ of openings and 40％ of windows of the building surveyed doesn't use noncombustible materials. Though it becomes the existing non-conformed building, it can satisfy the present standard by replacing openings with noncombustible materials.

현재 국내에서는 많은 경제성장과 생활여건의 개선에 따라 기존주택의 재건축과 재개발이 증가하고 있다. 이에 따라 국내에서 발생하는 폐기물중 건설폐기물이 차지하는 비중은 점점 더 커져가고 있다. 따라서 정부나 민간에서는 건설폐기물의 발생량을 줄이기 위해 많은 노력을 하고 있다. 그러나 건설폐기물의 발생량을 정확히 예측하고 관리하기 위한 시스템의 개발에 대한 노력은 거의 없는 실정이다. 폐기물의 발생량을 예측하기 위한 기준의 미비로 인해 많은 사회적비용이 발생하고 있다. 따라서 본 연구에서는 공동주택을 대상으로 건설폐기물의 발생량을 쉽게 예측할 수 있는 방안을 제시한다. 그 방법으로는 원단위 할용, CAD도면의 활용, 3D object의 활용과 같이 현장여건에 따라 적절한 방법을 선택하여 적용할 수 있도록 하였다. 이 모듈은 사용자의 사용 목적에 따라 개별 모듈별로 사용하는 것이 가능하도록 구성하였다.

경제수준 및 주거수준 향상에 따른 생활양식의 변화로 공동주택 입주자의 가족 구성과 주거 선호도가 다변화되고 있다. 이에 따라 라이프 싸이클 및 라이프 스타일 만족을 위한 리모델링과 조기 재건축이 늘어나고 있으며, 공동주택 주거 계획의 핵심요소로써 오픈 하우징의 개념인 "가변성"이 강조되고 있다. 주거공간에 공간 가변성을 채택한 공동주택들은 점진적으로 증가하고 있지만, 구조 안정성, 경제성 및 거주자 사용성을 만족시키는 최적의 공간 가변형 복합구조시스템은 개발되지 못한 실정이다. 따라서 본 논문은 기존 공간 가변형 공동주택의 복합구조시스템 개발과정 및 특성을 분석하여 시스템 평가요소를 도출하고, 이것을 기준으로 각 시스템을 비교${\cdot}$분석하여 국내 실정에 맞는 모듈화된 시스템 개발을 위한 현행 가변형 구조시스템의 개선 방향을 제시하였다.

Riverside forests make a river bank stable because trees of them hold together the stone and soil by roots and decrease the speed of running fluid by trunks. So they become known to have positive effects on flood prevention. So This study will be a basic study to preserve and restore of riverside forests. The goal of this study is to classify types of Han riverside forests between Yangpyeng and Yeoju gun. and find out sites of planting. Results of this study can be summarized as follows; The evaluation indicators were set up based on literature review and site survey. Two indicator categories were developed: natural environment and human environment. And they were divided into 5 sub-categories for calculating weights. As for the major indicator categories, the weighted index of natural environment is at 0.5. And the weighted index of human environment is at 0.5 followed by access at 0.15, the range of user at 0.15, cultivated land at 0.1 and legislation at 0.1. This study selected 53 sites for riverside forests planting. They were classified with types of bank(11), level-upped riverside(32), island(10). The amount of the length of 11 bank types is 23,050m, the area of 32 level-upped riverside types is $4,490,000m^2$ and the area of 10 island types is $4,590,000m^2$. After the evaluation of 53 riverside forests, this study selected 12 sites of riverside forests. They were two bank types, nine level-upped riverside types, and one island type. Rebuilding riverside forests are to accomplish the green network which links and divides region. It will be one of the best ecological methods to construct friendly environmental region.

Objectives: This study was conducted to investigate the current status and to suggest future directions for health management of teenagers who use healthy school tuck shops to improve teenagers' eating habits while reducing and preventing obesity. Methods: A total of 29 students (16 middle school students and 13 high school students) took part in the interview for this study, and the interview was conducted for each school's focus group by using qualitative research methodology. Results: The current status of using healthy school tuck shops and suggested future directions were divided into two categories. Personal barriers such as discrepancies between personal perceptions and behaviors and lack of food choice suitable to individual tastes can be solved by rebuilding the operating system to provide intuitive promotion of behavior and customized products through improvements in existing products and new product development. A lack of consistent management from low utilization convenience and difficulty in maintaining a constant purchase price can be handled by establishing a solution to restricted physical access for products, as well as seeking profit by improving distribution costs via continuous cooperation between the school and community. Conclusions: Continuous funding and a system that reflects the needs and preferences of healthy school tuck shop users should be applied for sustainable operation of healthy school tuck shops to improve teenagers' eating habits.

아리스토텔레스 이래로 많은 논자들이 인간의 능력을 존재의 형태로 파악해왔다. 주류경제학의 시장 분석, 맑스의 자본제적 노동과정 분석 심지어 사회주의 국가의 사회주의적 노동과정 분석에서 실행에 앞서 능력을 전제하였다. 물론 맑스는 자본제적 노동과정에서 능력의 가치와 실행의 가치가 다르고 생산자가 생산물을 자신의 것으로 가지지 못하는 타율성을 밝혀낸다. 사회주의적 노동과정이라고 해서 타율의 올가미를 벗겨내지 못했다. 타율의 올가미를 벗겨내고 능력을 최대한 발휘하기 위해서 발상의 전환이 필요하다. 발상의 전환은 구체적으로 노동을 수단이 아니라 삶 그 자체로서 목적인 본래의 노동으로 복원시키는 것이다. 인간의 능력은 잠재적이다. 잠재를 존재의 형태로 규정할 수 없다. 인간의 능력은 자유의지를 통해 고양될 수 있다. 자유로운 개인들의 연합의 '필요에 따른 분배' 원칙에 따라 (생활수단 뿐만 아니라 생산수단)의 개인적 소유를 재건함으로써 인간의 잠재적 능력을 고양하는 완벽한 자유를 구가할 수 있다.

This study is an analysis of the life of Max Planck (1858-1947), the in view of engineering literacy education. Some expressions describing Planck include "the father of German science", "the namer of Quantum". Furthermore, he is the scientist who permanently engraved his name in a scientific invariant called the Planck Constant. Planck had already made remarkable scientific achievements in his mid-ages, which became the springboard of quantum mechanics, but he went on to achieve much more in his old age. Between 1910s and 1930s, he was the director of the Kaiser-Wilhelm Gesellschaft, the Berlin Academy, and the German Physics Society, which is the German core research group. In the 1910s, he endured the terrible personal suffering of losing his three children and then succeeded in rebuilding German science in the 1920s in his golden age of 70s. His achievement was great not only as a scientist but also as a science administrator. His life was contradictory in several ways. While fundamentally being a conservative, he initiated a great scientific revolution. While making efforts to preserve traditional values, he was in the center of great many upheavals and destruction. While being the incarnation of honesty, he was also given to extremely delicate political positions. In his long career, Planck lived with all his might as a leader of the German science organizations and permanently left his name on the institute representing Germany. Planck succeeded in his work for the institutional development of science, philosophical understanding of science, and as a role model of exemplary scientist. His long life was accompanied by both achievements and failures, intangible and difficult to judge. Today, as research and development management and scientific leadership have become increasingly important, Planck's life may be a good example of engineering literacy education.

Purpose: The purpose of this study is to suggest the policy and scope of the concept of sports welfare and to present a systematic model enhancing sport welfare of the society. Research design, data, and methodology: In order to induce idea for welfare policy and conceptual sport welfare model, this study reviewed a literature discussing the functions and mechanism of sport in enhancing a sense of life quality and thus rebuilding welfare of community. Results: The study suggests these. First, sports welfare ensures the rights of sports of all citizens and has the main purpose of providing social services, creating environments against inequality, improving the quality of life and happiness for everyone to enjoy, and the range should be continued from the right to live, environments against inequality, to the improvement of life and happiness. Second, since the integrated perspective was first suggested, sports integration development will be researched as well as the direction of the development of policies of the integrated model. Basic research of indicator development will need to be proceeded to execute and evaluate the integrated model. Third, the improvement of treatment of sports welfare instructors is urgent. Namely, compared to sports-related budget and the enhancement of facilities, the poor environment of sports welfare instructors needs to be improved. Instead of only testing physical fitness and prescription, the business needs to be continued by connecting to the participants' continuous participation in sports. Conclusions: Whether sports welfare succeeds depends on the need for an active beneficiary, identification of demand, a beneficiary that can discover potential to join offline and online into one, the establishment of sports policies to promote competency development, and a direct progression is needed.
