전병관,나성주,김선화 동신대학교 환경연구소 2004 환경연구 Vol.9 No.1

우리나라에서 사육되는 주요 가축들을 대상으로 하여 2000년부터 2003년까지 4년 동안 주요통계자료를 바탕으로 가축의 사육 두수와 배출량, 처리시설 현황 등을 분석한 결과 축산분뇨 발생은 대부분의 가축에서 2002년 이후 소폭 증가하였다. 2003년 기준으로 우리나라의 축산분뇨 공공처리 시설은 47개소이며 자원화가 가능한 처리시설은 20개소로써 이는 전체 처리시설의 42.6%밖에 되지 않는 실정이다. 따라서 자원화를 위한 신규 공공처리시설의 확충이나 기존 공공처리시설의 보강이 필요할 것으로 판단된다. 개별 축산시설의 경우 신규축산 농가와 사육두수를 늘리는 축산농가에 대해서는 반드시 분뇨분리 시설을 설치하도록 유도함으로써 점차적으로 분뇨분리 형태의 축사시설을 정착화 시켜야하며, 지역현황이 고려된 적정 축산두수의 유지와 소규모 축산농가들의 계획된 축산단지로 이전 또는 공동시설화해야 할 것이다. After, based on the major statistical data from year 2000 to 2003, the number of domestic livestock-breeding, the status of treatment plants, and the amount of livestock's waste generation had been analyzed, the amount of livestock's excretions generated were increased within narrow limits. At the basic year of 2003, the public treatment plant of livestock's excretions in Korea were 47 places and among them, only 20 plants(42.6%) could make excretions into resources. Therefore, an expansion of new public treatment plants and reinforcement of the existing plants must be needed. At the individual breeding facility, new stock farmhouse and farmhouse who expands the number of livestock must be induced to set up the livestock's waste treatment plant. Hence, gradationally, livestock's waste treatment plants should be installed widely, and the proper number of the livestock should be maintained under the considered status of an area. Also, Small scale stock farmhouses should move to planned complex and collaborate.

One essential contribution to a successful soccer game, which is still not always recognised as such, is the standard and quality of the lighting system. This is not only for TV transmissions, but also for the general practising of the sports. But, on too many occasions, sport activities and events have been allocated with insufficient or Inappropriate lighting system. inadequate lighting spoils not only the pleasure and the interests of active sportsmen, but also the comfort of the spectators in both the stadium and at home watching their TV. So this paper newly proposes the algorithm for searching of luminaire position which can be applied to the design stage.

Objectives: For the purpose of preparing the fundamental data and assessing the status of exposure level of chemical substances in painting process. Methods and Materials: The author determined the concentration of organic solvents, lead(Pb), Chromium(Cr), and Toluene-2, 4-diisocyanate(TDI) in air of painting process to 90 industries classified by 15 types of manufacturing industry during a period from Jan. 1st 2001 to Dec. 31st 2001. Results: The results were as follows: 1. The geometric mean level of each chemical substance was 0.1706 ppm for exposure index in organic solvents, 0.0019㎎/㎥ for Pb, 0.0024 ㎎/㎥ for Cr, and 0.0004ppm for TDI, respectively. 2. The exposure level of each chemical substances by type of painting was the highest in dipping and brush painting for organic solvent, in spray-painting for TDI, and in spray gun-painting for Pb and Cr, respectively. 3. The exposure level of each chemical substances by type of local ventilation equipment was higher in enclosed and booth type for organic solvents. Cr, and TDI, and in exterior type for Pb, respectively than those of other types. 4. The exposure level of each chemical substances by type of hazardous material arresting media was higher in using water for organic substances, in using bag filter for Pb, TDI, respectively than those of other types. Conclusion: According to above results, this study suggests that the exposure level by type of industry exceeded the exposure level in wooden furniture and metal furniture manufacturing industry for organic solvents and Pb, respectively.

There are many kinds of complicated equipment in chemical plants. So, the chemical plants always have high possibility of accidents. Hazard analysis is one of the basic tasks to ensure the safety of chemical plants, but it is an arduous, tedious, time-consuming work and requires multidisciplinary knowledge, and demands considerable cognitive load from the analysts. To overcome these problems, there have been various attempts to automate this work by utilizing computer technology, particularly knowledge-based technique. However, many of the past approaches are lacking in properties: safeguard consideration, accident diversity, cause and consequence diversity, pathways leading to accidents, and various hazard analysis reasoning. Therefore, in this study, deviation analysis algorithm, malfunction analysis algorithm, and accident analysis algorithm were proposed using multimodel approach of representing a chemical process adequately for hazard analysis in view of function, behavior, structure, and material property. Unit knowledge base is devised to model a process unit. It consists of unit behavior model and unit function model. In unit knowledge base, a process unit is modeled in different terms of variable and function. Variables describing unit are divided into inlet, internal, and outlet variables explicitly, by interconnecting behavior model and function model through these variables. This model represents physical hazards. In structure model, process is separated into several streams which represent different connections. In material knowledge base, chemical properties are considered according to NFPA code. A hazard analysis system, AHA, was developed on G2. The system was applied to feed section

체육교과에 대한 중학생의 선호 순위 및 요인 분석

이병관(Byoung Gwan Lee) 한국스포츠교육학회 2005 한국스포츠교육학회지 Vol.12 No.1

본 연구는 제7차 교육과정에 제시된 국민공통기본교육과정의 10개 교과 중 체육교과에 대한 중학생들의 선호순위와 그 순위에 영향을 미친 요인들을 분석하고, 차후 학생들이 사회생활을 하는데 있어서 어떠한 도움을 줄 것으로 인식하는가를 분석하는데 그 목적이 있다. 본 연구결과와 논의를 통해 도출한 결론은 다음과 같다. 첫째, 중학생들은 10개 교과 중 체육을 가장 선호하고 있었으며, 그 주된 요인은 교실 밖에서 이루어지는 재미있는 수업으로 인식하고 있기 때문이었고, 또한 신체적·심리적인 효과를 경험하고 있기 때문이었다. 하지만, 기능중심, 경쟁중심, 남성 성향중심적인 수업과 시설·기구의 부족으로 인해 체육수업에 대해 좋지 못한 인식과 더 나아가 체육수업에 대한 기피현상까지 초래할 수 있으므로 다각적인 측면에서 체육수업을 개선하려는 노력이 필요하다. 둘째, 10개 교과 중 체육은 타교과보다 차후 사회생활에서 도움이 덜 되는 교과로 인식하고 있었으며, 그 주된 요인은 학교체육과 사회체육과의 단절현상, 엘리트체육중심의 문제점 등으로 인해 체육과 직·간접적으로 관련된 직업에 도움이 될 것으로 인식하고 있었다. 따라서 체육교사는 학교체육수업을 통해 학생들에게 스포츠와 운동에 대한 호의적인 태도를 형성시키려는 지속적인 노력과 함께 학교체육에 대한 인식 및 태도 전환을 위한 홍보전담기구를 설치하고 활용하는 방안이 필요하다. The purpose of this study was to analyze middle school students` preference ranking for physical education among ten subjects in the 7th curriculum, and preference factors for the ranking of physical education. To achieve this study, quantitative and qualitative research methods were used simultaneously. Participants of this study were 659 middle school students. The conclusions of this study were as follows. First, physical education was acknowledged as the most preference subject among ten subjects in the 7th curriculum. And preference factors for the ranking of physical education were analyzed four categories; (1)interesting subject enforced outside the classroom (2)subject obtained physical effects and psychological (3)subject experienced of one`s physical insufficiency (4)subject influenced by environments` conditions. Second, physical education was acknowledged less assisted subject than others among ten subjects in the social life. And factors for the ranking of physical education were analyzed three categories; (1)subject was useful for professions related with physical education (2)subject obtained physical strength and health (3)subject obtained mental effects and social.
