Recorded injury identified the role of falls in producing injury througout all segments of the nation. The Economic and social costs arising from falls has been established in numerous sources, both nationally and from the intermational literature. Recorded injury also indicated the potential features of falls, the need for a basic understanding of the energy exchange mechanism involved and the subsequent rehabilitation processes required. It appears unlikely that any other major cause of injury has an etiology so little researched and consequently, so little understood, which in turn has prevented the development of an intervention strategy or a scientically based control technology of falls. This paper will emphasize how the postural changes of foot are related to slip/fall severity in different environmental conditions. Lidewise, we will examine the whole slip/fall cycle through the biomechanical parameters involved in a range of walking speed and floor slipperiness

In design PV (photovoltaic) system, there are many important factors to consider for best site selection. It is essential to understand to know the amount of sunlight available and how to minimize the shadings. This study presents basic concepts for understanding sun's position and insolation. also it gives easy tools for topography analysis. Finally, this study shows some theoretical calculations of power generation losses by topographic obstacle's elevations and disadvantages in economic feasibility, that is about 7million won loss per year for case of 10 degree topography elevation with assuming average Korea's topography elevation as 5 degree.

The constant evolution of society, culture and scientific technology, coupled with changes in life style and behavioral patterns, has led mankind to peroeive diverse needs for space. Particularly, the rapid structural change in the field of marketing has entailed changes in techinques for construction and presentation of space for an improved marketing environment. To satisfy such new, diverse needs for space, interior designers will have to redefine the "mankind and environmen( concept and examine their design methodology anew. The question of how to design available space for a certain purpose will remain a daunting task for designers in the future, as it has been in the past. In the pursuit of convenience and conformity to mankind's surroundings, every nation has, in common with other nations, basic design elements, design skills and other factors. In designing camercial space in a particular region, it is essential, however, to have a proper understanding of the social economic and cultural context indigenous to that region, as well as the impact on environmental and ecological change and marketing strategy. This study discusses design metholdology for the comming camercial space on the basis of the space concept and current status in Korea, with major emphasis on Korea's regional characteristics.

In case of domestic pyrolysis dry distillation gassification technology, it stays at the stage of its early introduction and development. Moreover, the companies possessed of this technology are limited to Japan and some countries in Europe, and domestic operative performance of this system is nominal, so there exist a lot of difficulties in securing its basic data. In addition, considering its operation and management, there happens a corrosion of metals by the production of corrosive gases in time of combustion of waste, and there arise a problem of occurrence of low temperature corrosion on exterior casing or gas ducts of a combustion chamber due to the high temperature corrosion around the burner of an incinerator, lowering the durability of an incinerator. Therefore, this study looked at the problems arising in time of incineration by understanding the characteristics of the pyrolysis dry distillation gassification incinerating facility, and did research on the improvement plan for durability of an incinerator for more economic, efficient waste incineration.

고준위방사성폐기물은 원자력 발전을 실시하는 국가에서는 반드시 해결해야 될 문제 가운데 하나이다. 대부분 고준위방사성폐기물 처리를 고민하는 나라에서는 지하 심부의 깊은 곳에 처분함으로써 인간사회로의 완벽한 격리를 고려하고 있다. 이러한 완벽한 격리를 위해서는 지하 심부에 위치하고 있는 암반의 특성을 파악하는 것이 매우 중요한 일이다. 특히 노출된 핵종이 이동을 통해 지표로 올라오는 것을 예측하기 위해서는 이동 경로가 되는 불연속의 특징을 이해하는 것은 무엇보다도 우선시 되어야 할 사항이다. 본 연구에서는 화강암과 편마암이 분포하는 지역에서 획득한 심부 500m 이하의 시료를 활용하여 각 암종별 분포하고 있는 불연속면의 특성을 이해하고 주변 환경과 고려하여 지하에 분포하고 있는 절리면의 특징을 분석하는데 그 목적이 있다. 이를 위해서 지하 500m에서 획득한 시료에 대한 육안분석을 통해 불연속면의 종류를 분류하고 각 불연속면의 분포특성을 분석하였다. 본 연구는 조사지역의 지하에 분포하고 있는 불연속면의 특징을 이해하는 기초자료로 활용될 수 있으며 추후 암종에 따른 불연속면의 분포 특징을 이해하는데 중요한 자료로 활용될 수 있을 것으로 기대한다.

As a neighboring country belonged to the same cultural sphere with the Northeast Asia, China is recently emerging as a center of the world's economy. The social transformations caused by the rapid economic growth are bringing changes in the Chinese housing culture and thus, it is considered that the identification of a user's need concerning a new housing space and social and cultural understanding on China are necessary. Accordingly, this research intended to conduct the basic research on the Chinese housing space design by observing the small apartment users in Shanghai area in terms of not only the tangible element of the residential space type but also the intangible elements such as lifestyle, values, behaviors, etc. The research range was limited to the kitchen area at the center of a house as a place where the exchanges among the family members are most frequently occur, and the research was carried out in the following methods. First, the effective user research method for the analysis of the Chinese small apartment kitchen users was studied through the literature investigation. Second, the 6 families of a research target were selected focused on the small apartments in Shanghai, China and the user research was performed using three methods of User observation, Video ethnography, and Contextual inquiry. Third, the research results were analyzed focused on the flow of human traffic in the kitchen area and user's behaviors. What were identified as a result take account of the human traffic movements in the kitchen areas around the sink-counter-cook top, cooking behaviors and meal areas outside of the kitchen. Through this, the need for the effective organization of the sink-counter-cook top, arrangement of meal area, and placement of storage by section for the kitchen space of China were drawn based on the understanding of the cooking process, and it was identified that such results require comprehensive understanding of Chinese housing culture.

This study investigated the appearance management aspects of middle-aged male CEO's based on Bourdieu's class theory. We conducted in-depth interviews with male CEOs in their 40s and 50s to understand the characteristics of appearance management in terms of economic, cultural and social capital. We found that they acquire educational capital based on their parents' economic capital and form their own cultural capital as adults. They had the characteristics of Petit Brujois, which aimed for a higher class. The characteristics of differentiation based on appearance management identified three results came from solidifying one's class position: clothing management, diversifying and upgrading appearance management, and pursuing their own ideal image. The influence of social network and cultural capital was also observed in appearance management. This study explored the characteristics of discriminatory appearance management through an in-depth study of middle-aged male CEOs as well as contributed to understanding the context of capital and appearance management by applying Bourdieu's class theory. In addition, this study provides basic data that can be referred to a design and marketing direction for the men's clothing market by providing information on male consumers with high purchasing power.

본 연구에서는 북한의 "바다오염방지법"에 대해 법적 경제적 함의에 대해 분석하였다. 이를 위해 북한의 관련법령과 우리나라의 법률, 제한적인 정보와 기존 연구문헌을 통해 비교분석하였다. "바다오염방지법"은 북한의 해양환경관련법령 중에서 기본법의 성격을 가지고 있다. 그러나 남한의 관계 법률과 달리, "바다오염방지법"은 환경권이나 행복권 추구라는 민주시민의 기본권리 보장보다는 해양오염방지를 통한 자원의 확보를 강조하고 있다. 또한 각급 국토환경보호기관(관련기관, 기업체, 단체 포함)의 실질적인 정책시행 등에 대한 제반규정이 적다. 북한의 법령체계의 특수성을 고려한다고 하더라도, 실행체계에 대한 미비로 인해 법의 실효성에 문제가 있을 것으로 판단된다. 이 법의 경제효과분석을 위해서는 자료축적이 필요하다. 향후 통일을 대비한 남북한의 법령제도통합을 위해서는 비교적 이념중립적인 환경관련법령을 통한 접근이 중요하다.
