The purpose of this study is derived by Utilization Strategy for Rural empty houses stability of Return to the Farm and Rural. The main findings can be summarized as follows. First, the recent return to the farm and rural has increased, and life patterns of diversification, and the retirement of the baby boomer generation return to the farm and rural ratio differed by region. Second, the required first order accurate and detailed to maximize the utilization of the rural empty houses Survey, and the integrated management system based on it should be built. Third, the public lead in pushing for policy to take advantage of an empty house, leasing and management capabilities by strengthening return to the farm and rural characters, revitalizing rural and residential stabilization is necessary. Finally, in order to enhance the utilization of the rural empty houses should prepare return to the farm and rural, Multi-Habitation and a common space for existing residents for a variety of purposes. The results of these studies has a significance that can promote rural housing return to the farm and rural, resource utilization and stable settlement, and rural areas activated at the same time. Utilization of specific rural empty houses feasible policy being prepared, by linking rural areas that can bring effects on the activation of alternative hope.

This study is an attempt to quantify rainwater utilization and miscellaneous water demand in Tokyo's 23 special wards, the core of the urban area in Tokyo, Japan, in order to elucidate the potential of further rainwater utilization. The rainwater utilization for miscellaneous appropriate water demands, including toilet flushing, air conditioning, and garden irrigation, were calculated for six different types of building: residential house, office, department store, supermarket, restaurant, and accommodation. Miscellaneous water demands in these different types of building were expressed in terms of equivalent rainfall of 767, 1,133, 3,318, 1,887, 16,574, and 2,227 (mm/yr), respectively, compared with 1,528 mm of Tokyo's average annual precipitation. Building types, numbers and its height were considered in this study area using geographic information system data to quantify miscellaneous water demands and the amount of rainwater utilization in each ward. Area precipitation-demand ratio was used to measure rainwater utilization potential for miscellaneous water demands. Office and commercial areas, such as Chiyoda ward, showed rainwater utilization potentials of <0.3, which was relatively low compared to those wards where many residential houses are located. This is attributed to the relatively high miscellaneous water demand. In light of rainwater utilization based on building level, the introduction of rainwater storage mechanisms with a storage depth of 50 mm for six different types of buildings was considered, and calculated as rainfall of 573, 679, 819, 766, 930, and 787 (mm), respectively. Total rainwater utilization using such storage facilities in each building from 23 wards resulted in the retention of 102,760,000 $m^3$ of water for use in miscellaneous applications annually, and this volume corresponded to 26.3% of annual miscellaneous water demand.

가수율을 변화시켜 취반한 밥의 관능검사, extrusion test, 수분함량측정 등의 실험을 통해 질지도 되지도 않은 보통의 밥상태를 만들기 위해 필요한 취반 가수율을 결정할 수 있었다. 밥의 압출력은 밥의 경도에 대한 관능 검사치와 정의 상관, 수분함량과는 부의 상관을 보였다. 관능 검사에서 질거나 되지 않은 보통밥상태로 평가된 밥의 수분함량은 62.3%, 압출력은 59.7kg이었으며, 이때의 가수율은 1.46배였다.

석탄의 수요증가와 소비는 석탄의 이용과정에서 생성되는 고형페기물의 처리와 관련된 문제들을 증대시켰다. 석탄 부산물의 주요한 이용은 건설과 관련돼 적용되었다. 석탄부산물의 하나인 플라이애쉬는 폐기물 재활용 생산의 일부분으로 설명될 수 있기 때문에, 과학적인 조사의 대다수는 많은 사용에서 플라이애쉬의 활용에 관하여 초점이 맞춰졌다. 반면에, 바텀애쉬의 재활용에 관해서는 관심을 기울이지 않았다. 이러한 소홀함의 결과로서, 많은 양의 바텀애쉬가 처리장에 쌓여왔다. 따라서, 바텀애쉬의 적당한 이용을 위한 안전하고 경제적인 해결을 얻기 위한 필요성이 좀 더 긴급하게 되었다. 논문에 나타낸 연구는 오토클레이브 경량기포콘크리트를 제조하기 위해 사용된 바텀애쉬의 성능 특성을 확인하기 위해 계획되었다. 실험실 측정 결과, 토버모라이트는 수열합성반응을 위한 재료로서 바텀애쉬가 사용되었을 때 생성되는 것으로 나타났다. 분산분석에 따른 결과로서, 기포슬러리의 굳지 않은 상태에서 물비는 플로우와 슬러리의 밀도에 영향을 미치는 것으로 나타났지만, 기포비는 슬러리의 밀도에만 영향을 끼치는 것으로 나타났다. 굳은 상태에서에서 기포비는 경량기포콘크리트의 절건밀도와 압축강도에 영향을 끼쳤지만 휨강도와 인장강도에는 영향을 끼치지 않았다. 반응표면분석의 결과에서, 목표성능을 얻기 위한, 바텀애쉬를 사용한 경량기포콘크리트의 최적배합조건은 물비 70$\sim$80%, 기포비 90$\sim$100%로 나타났다.

현재 우리나라의 FTA 활용률은 선진국의 경우에 비해 전반적으로 활용률이 낮다. 특히 한-ASEAN FTA의 경우 30% 대에 그치는 등 FTA 활용 제고가 시급한 과제로 부상하고 있다. 또한 무역기업이 FTA 특혜관세를 적용받는 비율도 저조한 것으로 평가되고 있어 활용률 제고가 최대 정책현안으로 나타나고 있다. 본 연구는 무역기업의 FTA 활용률을 높이기 위하여 실태분석을 실시하였다. 무역기업의 FTA 애로사항을 파악하였고, 무역기업의 FTA 활용교육과 컨설팅의 개선방안도 검토하였다. 이는 정부의 FTA 활용제고 시책 마련에 유용한 자료를 제공하는데 목적이 있다. 본 연구결과로 FTA를 활용한 무역기업의 수출확대, FTA 정책의 내실화, FTA 정책지지 기반강화에 기여할 것을 기대한다.

This study was carried out to compare the protein quality of lamb and beef meat. by feeding to growing rats. Sixty weanling rats, 30 males and 30 females, were blocked into 12 groups(6 gruops of males and 6 groups of females). They were fed casein. beef, or lamb as a protein source at two levels, 6 and 15%, for 5 weeks. The amount of food intake. food efficiency ratio, protein efficiency ratio. body weight gain. and the weights of skeletal muscles and liver were measured. Nitrogen retention, protein content in the liver and skeletal muscles, and the levels of protein and cholesterol in the serum were also assayed. Summarzing the results, there were no significant differences between lamb and beef on the growth and nitrogen utilization in the rats fed same percentage of protein diet. However. rats fed 15% protein diet showed significantly higher growth rate than those fed 6%. Therefore, it can be concluded that lamb is as good a protein food as beef in terms of protein quality.

In sheet metal forming process, it is very important to nest blanks optimally to get a maximum utilization ratio(UR) to reduce waste of material. Optimal Blank Nesting algorithm is developed about single nesting, double nesting, fixed slitting width and free slitting width. This algorithm was applied to various practical blanks which are under production. Then new optimal nesting configuration was obtained and higher UR was achieved by this program in each cases.

Value-added utilization of the disposed ash trees due to the infestation by Emerald Ash Borer (EAB) was explored by converting them into particleboards (PBs) and wood-plastic composites (WPCs). The experimental result showed that PB panels could be successfully manufactured from the ash wood but compaction ratio need to be higher than 1.3 in order to meet the standard requirements listed by American National Standards Institute (ANSI). Ash wood plastic composites with high density polyethylene (HDPE) and polypropylene (PP) were also prepared with additives by extrusion. Physical and mechanical properties of ash wood plastic composite compared favorably to those made of pine and maple.
