우리나라 건축법에 따르면, $200m^2$ 이상의 대지 위에 건축행위를 하기 위해서는 반드시 일정면적비율 이상의 식재를 실시해야 한다. 대규모 개발에서는 이 법규가 잘 지켜지나, 소규모 개발에서는 잘 지켜지지 않고 있기 때문에 소규모 개발에 대해서는 특별한 관심이 기울여져야 한다. 따라서 이 연구의 목적은 대지의 조경에 대한 국내외 사례를 분석하고 서울시에서 소규모 대지에 대한 조경관리 실태분석을 통해 소규모 대지의 조경 설치 및 사후관리에 대한 합리적인 개선 방안을 마련하는 것이다. 이 연구에서는 2002년도에 서울시 성북구와 강남구를 대상으로 조사된 조경 실태자료를 사용하였고, 추가 현장조사와 담당공무원 및 건물소유주에 대한 설문조사를 수행하였으며, 그 분석결과를 토대로 건축단계별로 개선방안을 도출하였다. 결과를 요약하면 다음과 같다. 첫째, 건축설계 상위계획 단계에서는 조경기준의 강화, 지구단위계획에서의 지침 제공, 인센티브 제도의 도입 등을 제안하였다. 둘째, 건축설계단계에서는 설계지침 및 사례집 제작 보급, 합벽개발 허용, 연면적 2,000m2 이상 건축물 건축에서 조경기사의 직접참여 또는 협력 의무화 법조항 신설 등을 제시하였다. 셋째, 건축허가 및 준공, 사후관리단계와 관련하여 조경에 대한 허가서류 검토에 녹지직 공무원 참여 보장, 현장 검사 및 확인 업무에 조경전문가가 참여할 수 있도록 관련규정의 개정 등을 제시하였고, 사후관리에 조경전문기술자가 대행 또는 참여할 수 있도록 허용하는 관련 규정 개정 필요성 등을 제시하였으며, 시정명령 미이행 또는 위법건축물에 대한 관리감독 강화의 필요성을 제기하였다.

연구의 목적은 Small-Scale Chemistry(SSC)를 적용한 수업이 고등학생의 과학성취도 및 과학관련 정의적 특성에 미치는 효과를 알아보는 것이다. 이를 위해 제 7차 교육과정의 고등학교 과학 교과서 화학영역에 대한 SSC 실험 프로그램을 개발하였다. 실험집단에는 SSC 실험 프로그램을 적용하고 비교 집단에서는 교과서를 중심으로 한 전통적 실험 수업을 실시하여 사전-사후 과학성취도 및 과학관련 정의적 영역의 변화를 조사하였다. 연구결과에 의하면 SSC 실험 프로그램을 적용하여 수업한 실험집단의 성취도가 교과서 내용의 전통적인 실험수업을 실시한 비교집단에 비해 유의미하게 높았다(p<.01). 과학관련 정의적 영역의 경우, 흥미와 과학적 태도 영역에서도 SSC 실험집단이 비교집단에 비해 유의미하게 높은 것으로 나타났다(p<.05). 또한 SSC 적용 수업에 대한 학생들의 인식을 살펴본 결과 학생들은 대부분 과학학습에 있어 효과적이고 흥미 있는 수업이라고 응답하였으며, 과학성취도와 정의적 영역의 변화를 잘 설명해주고 있었다.

Not only does the labor of manufacturers used most in the drying process after rice harvest, but it also is having huge influence in quality. Also, because drying storage of rice production around the whole country is scarce with original facility, it has become a very important matter that farms develop their own safe and high-quality facilities to store and dry rice. Therefore, this study developed a small scale accumulated storage and drying bin, assessed nalyzed drying properties, and conducted analysis of research on the property of quality when storing for a long time. As a result, the drying speed of the small scale accumulated storage and drying bin was adequate of 0.042%/hr and was shown that the experimental static pressure and theoretical static pressure corresponded. Also, it was shown that drying cost was up to about 6 times inexpensive that heated air drying. For the storage of the small scale accumulated storage and drying bin, average of moisture content was around 16.5 until early April and decreased to 15.7% in July. Inside storage was maintained to 12.13% until early April and slightly increased to 14% after May. It was shown that inside storage had higher hardness and rate of cracking than the small scale accumulated storage and drying bin by storage conditions and germination rate was shown a little higher when stored in the small scale accumulated storage and drying bin.

This study was performed to identify the current status of work environment management and to provide appropriate recommendations for small scale industry with less than 5 workers from September, 2000 to October, 2000 in Seoul city and Gyoung-gi province. The 211 companies were surveyed by checklist included the elements of management of work environment, hazardous chemicals, MSDS, personal protective equipment, and ventilation system. The proportion of metal products manufacturing and printing industries are 25.6 % and 22.3%, respectively. The daily working hours in printing industry is longer than others. The industries that produce potentially hazardous agents, such as noise, dust, metal, organic solvents, radiation and chemical material are pulp, plating, machinery, and printing, respectively. In above industries, only 2.8 % of those recognised and had MSDS. The proportion of companies providing fire extinguishers, safety showers are found to be 13.3 %, 7.1 %, respectively. Only 24.2 % of companies provided personal protective equipment to the workers. The ventilation system was operated in most of companies. But local exhaust ventilation system is provided to 22.3 % of those, also had not been annually inspected. This study showed that the current status of occupational safety and health was not appropriate for workers in small scale industries. It is suggested that annual physical examination have to be performed, MSDS usage must become widespread, and employer and emplyees in small scale industry should be educated for the treatment and storage of hazardous chemicals to improve the occupational safety and health of the working environment. also, regulatory standard has to be applied to local exhaust ventilation system in small scale industry to improve the working condition.

Purpose: The small-scale environmental impact assessment system in Korea was introduced and implemented in August 2000, but it has a problem that it cannot guarantee implementation due to the large proportion of qualitative reduction measures for each evaluation item. Therefore, when preparing a small-scale environmental impact assessment, research was conducted on how to improve the existing simple listing-type reduction measures and qualitative evaluation standards to quantitative reduction measures and evaluation standards reflecting regional characteristics. Research design, data and methodology: The small-scale environmental impact assessment system in Korea was introduced and implemented in August 2000, but it has a problem that it cannot guarantee implementation due to the large proportion of qualitative reduction measures for each evaluation item. Therefore, when preparing a small-scale environmental impact assessment, research was conducted on how to improve the existing simple listing-type reduction measures and qualitative evaluation standards to quantitative reduction measures and evaluation standards reflecting regional characteristics. Results: As a result of the analysis of qualitative and quantitative factors, the arithmetic sum of the qualitative factors of the total six projects is 160, accounting for 80% of the total number of reduction measures, and the quantitative factors are 40, accounting for 20%. Among them, the number of qualitative reduction measures reached 97.4% for animal and plant items, and more than 90% for air quality, noise and vibration, and eco-friendly resource circulation items. Conclusions: Therefore, it is necessary to avoid establishing qualitative reduction measures and set quantitative measures as the basis, but to specify the specifications, size, and installation location related to the reduction measures, and to calculate the numerical reduction efficiency.

The effects of design parameters for small scale hydro power(SSHP) plants due to rainfall condition have been studied. The model to predict hydrologic performance for SSHP plants is used in this study. The results from analysis for rainfall conditions based on Weibull distribution show that the capacity and load factor of SSHP site had large difference between the variation of shape and scale parameter. Especially, the hydrologic performance of SSHP site due to variation of shape parameter varied more sensitive than the case of variation of scale parameter. And also, the methodology represented in this study can be used to decide the primary design specifications of SSHP sites.

Testing of steel roof purlins is usually performed on full scale models in large vacuum test rigs. To undertake a comparison between web cleat connected purlins and flange bolted purlins a series of tests were performed on a 1:4 small scale model vacuum test rig. Various modelling issues need to be addressed to ensure reasonable comparison with actual constructed roof framing methods but still be suitable for an economical comparison between the connection methods. Model test results were supported by, and found to be in reasonable agreement with, deflection predictions from computer models based on finite element methods. This paper discusses the testing methods adopted and the value of small scale model testing programs as a means of obtaining comparisons between framing options.
