Indoor climate control equipments is used to make the indoor environment more comfortable when indoor condition is not satisfactory to inhabitants. In this study, which instrument is preferred to control indoor climate and which is not preferred were surveyed with questionnaire. With this result, the needs of dwellers and wanting performance of housing could be revealed. Results are followings 1) The satisfaction ratio and equipment possession ratio of apartment houses' is higher than that of detached dwelling's 2) It is recognized for inhabitants that air cleaner is the mostly used equipment and best equipment for indoor comfort. 3) Electronic fomentation mat is recognized as the most problematic equipment for securing inhabitant's comfort. And air conditioner is considered negative for 60% of responser's. As grow older, this trend is increasing.

In this paper, we analyze customers' working electric energy (kWh) which is served pole-transformer in order to reduce peak load current error which is generated in application load correlation equation. The characteristic of electric load which customers are using is classified by customer's working electric energy (kWh) and ratio of cooling equipment possession. For the input data of fuzzy model, we used to kWh on April which represents basic load and kWh which is increased from April to August. The April kWh is used to classify into large, medium, small customer. Also, the increased kWh is used to know information of cooling equipment possession. For the output value of fuzzy model, we can determined peak load current limit in application load correlation equation.

최근 기업의 경영환경은 급속한 글로벌화와 신기술의 출현에 따라 항상 경쟁과 도전에 직면하게 되어 있다. 기업이 이러한 환경을 타개하기 위해서는 끊임없는 연구개발을 통해 경쟁우위의 기술을 지속적으로 확보해야 한다. 따라서 기업이 연구개발 활동을 원활히 할 수 있도록 하는 지원이 필요하며, 이를 위해 기업의 연구개발 활동에 영향을 미치는 요인에 대한 보다 세밀한 연구가 축적되어야 할 것으로 보인다. 본 연구의 목적은 첫째, 중소기업의 연구개발투자 영향요인을 규명하는 것이다. 기업의 연구개발투자에 영향을 미칠 수 있는 요인들을 선행연구 조사를 통해 추출하고, 이를 요인들이 중소기업에는 어떠한 영향을 미치는지 확인하고자 한다. 둘째, 중소기업을 산업현장의 분류기준에 따라 유형을 구분하여 각각 영향요인의 유의성 및 영향도에 차이가 있는지 확인하는 것이다. 창업기업, 기존기업 등 유형 구분에 따라 각각 다른 특성을 나타날 수 있음을 확인할 수 있을 것으로 본다. 연구 결과, 중소기업의 연구개발투자에 영향을 미치는 요인 중 기업규모 요인인 종업원 수, 매출액, 연구 인프라 요인인 연구원 비중, 기술능력, 장비보유율, 지적재산권, 그리고 연구 활동성 요인인 아이디어 활동, 공동연구 비중 등이 정(+)의 영향을 미치고 있으며 연구 활동성 요인 중 CEO 참여는 부(-)의 영향을 미치고 있음을 알 수 있었다. 또한 중소기업을 업력, 제품, 거래형태, 기술수준 등에 따라 구분할 경우 연구개발투자에 미치는 영향정도와 유의성이 다름도 확인하였다. 이상의 결과를 바탕으로 학문적, 정책적 의의를 제시하였다.

The construction of the equipment of water utilization has been developed since the ancient Korea period, 1906 in order to develope and modernize the agriculture. As the results, 83% of total paddy field area, 1,268,949.8 ha has developed into the irrigated paddy field, and the rest of area, 17% has remained nonirrigated paddy field (due to the data of the statistics of 1975). The ratio of the irrigated paddy field area among the total weir was marked 13.14% (area, 137,926.3 ha) and the third grade of total irrigated paddy field in accordance with the facilities of water utilization. In case of Gangwon-Do, the 44.18 percentage of the total irrigated paddy field, 51,057.2ha has been and pointed out first grade. As the results, we found out the following articles : 1. The total weir, 1,641 that sumed concrete weir 647 and conventional weir 967 has been constructed and has irrigated the 44.l8% of total irrigated paddy field of Gangwon-Do. 2. These weirs have been public possession of those villages to be 96.1 percentage of total weir and was controled by them. 3. Those weirs that were constructed across tributary (first, secondary and third tributary) at vallies (elevation 100∼1,000m) have marked that 45 percentage of total number of catchment area has 100∼1,000 ha, and 70 percentage of total number of basin area has been below 10 ha and has constructed about 5 of step-shape. 4. The construction of most weirs has became generally about 50m length, about 1m height. 5. The 80 percentage of newly constructed concrete weir has aged below 10 years. It seemed that 79 percentage of conventional weir has aged over 20 years and 41% of contructed weir has needed to be improved quickly. 6. If privious weirs, 296 will constructed newly, they can irrigate 3,600.8 ha of paddy field and 45.8% of total irrigated paddy field will have been and will contribute to the production of much rice.
