The aim of this paper is to study the mechanical behaviors of the cold-formed thin-walled steel and reinforced concrete sandwich composite slab (CTS&RC-SCS) under vertical loads and to develop the calculation methods of its flexural bearing capacity and section stiffness. Two CTS&RC-SCS specimens were designed and manufactured to carry out the static loading test, and meanwhile, the numerical simulation analyses based on finite element method were implemented. The comparison between experimental results and numerical analysis results shows that the CTS&RC-SCS has good flexural capacity and ductility, and the accuracy and rationality of the numerical simulation analysis are verified. Further, the variable parameter analysis results indicate that neither increasing the concrete strength grade nor increasing the thickness of C-sections can significantly improve the flexural capacity of CTS&RC-SCS. With the increase of the ratio of longitudinal bars and the thickness of the composite slab, the flexural capacity of CTS&RC-SCS will be significantly increased. On the basis of experimental research and numerical analysis above, the calculation formula of the flexural capacity of CTS&RC-SCS was deduced according to the plastic section design theory, and section stiffness calculation formula was proposed according to the theory of transformed section. In terms of the ultimate flexural capacity and mid-span deflection, the calculated values based on the formulas and the experimental values are in good agreement.

Objective : Pheochromocytoma may arise within the adrenal medulla, or in other locations, where symptheic ganglia or chromaffin tissues are known to exist. Approximately 0.1 % of hypertensive patients have Pheochromocytoma, This study is to report the clinical effects of ShiHo-GuiZhiTang on pateints who have suffered from such symptoms of Pheochromocytoma as sweating, hypertention, Indigestion, anxiety neurosis, nausea, headache, and epigastric discomfort. Method : ShiHo-GuiZhiTang was used for a patient who had suffered from symptoms of Pheochromocytoma which was diagnosed as Banpeubanri-jueng of soyang disease in Sanghan-Ron. Result : In treating the patient with symptoms of Pheochromocytoma with ShiHo-GuiZhiTang, results were good. Conclusion : The results of this study suggest that ShiHo-GuiZhiTang is effective for such symptoms of Pheochromocytoma as sweating, hypertention, Indigestion, anxiety neurosis, nausea, headache, and epigastric discomfort.

Objectives : This is what tries to study irregular pairs between five viscera and five tatstes. And than tries to make convincing explanation. Methods : We analysed "SuWen ZangQiFaShiLun素問 藏氣法時論", "YiXueQiYuan醫學啓源", "TangYeBenCao湯液本草", "BenCaoGangMu 本草綱目" and "FuXingJueZangFuYongYaoFaYao輔行訣臟腑用藥法要". We found difference and similarities between these books. Result & Conclusions : "YiXueQiYuan", "TangYeBenCao", "BenCaoGangMu" inherit pairs between five viscera and five tatstes from "ZangQiFaShiLun". "YiXueQiYuan" had added examples of herbs to "ZangQiFaShiLun". "TangYeBenCao" had added examples of priscriptions to "ZangQiFaShiLun". "BenCaoGangMu" had added examples of herbs to "ZangQiFaShiLun". But new pairs between five viscera and five tatstes had suggested in the "FuXingJueZangFuYongYaoFaYao". We think that the new pairs are more logical than the others.

Structural analysis of compound words is necessary and an important process in natural language processing. Proposed here is a corpus- and statistics- based method for the structural analysis of compound words in Japanese. We determine the structure of a compound word by using Internet corpus and calculating the strength of word association among its constituent words. Experiments with 5, 6, 7, and 8 kanji compound words show that our method works well and its performance is better than those of other comparable studies.

어가경제조사는 우리나라 어가의 어가경제 및 어업경영에 관한 사항을 조사하는 통계조사이다. 본 연구는 어가경제통계를 생산할 수 있는 표본설계를 제안한다. 연구의 기초 자료로 1990년 어업총조사 자료를 이용하였으며, 시.도별 통계를 위하여 시.도를 부차 모집단으로 하여 설계를 하였다. 표본은 층화 2단 추출을 하였으며, 층화를 위하여 어가소득의 소득함수를 추정하여 이용하였다. 어가의 소득은 선형 추정량을 이용하여 추정하였다.

A case study of foodwaste treatment was conducted to compare the impacts of four scenarios: incineration, incineration after biogasification, biogasification followed by composting, and composting. Potential contributions to climate change, acidification, consumption of landfill and human toxicity were assessed. Characterization of human toxicity caused by metals and PCDD/DF was performed by three multimedia fate models. Scenarios with a biogasification process showed lower impact on climate change and human toxicity. The ranking of four scenarios on human toxicity varied depending on the characterization models applied. The steady state models placed high priority on emission of heavy metals to farmland, whereas the dynamic model estimated the emission of PCDD/DF from the incineration process as more significant.

A prototype of 76 ha Shi-hwa constructed wetland was constructed for the first time in Korea to purify severely polluted stream water. Hydrology, vegetation(macrophyte) and water quality for Banwol and Donghwa wetland built in Shi-hwa tidal reclaimed area were monitored to evaluate the performance of the wetlands. The overall efficiency for the treatment of polluted stream water using the wetlands showed no significant improvement. The monthly average removal rates on SS, BOD, TN and TP for Banwol and Donghwa wetlands showed 66.5% and 62.8%, 14.8 and 34.3%, 33.9 and 47.1% and 20.8 and 51.6%, respectively. It is considered that three major factors, ie. wide fluctuations in inflow rate, short hydraulic retention time and small open area compared with vegetated area could have a great influence on low system efficiency.

부분방전 진단 기술 분야에서는 노이즈의 영향을 최소화할 수 있는 기법이 요구되고 있는 실정이다. 본 논문에서는 부분방전과 노이즈 신호 추출을 위한 로그앰프의 반응 속도차와 부분방전 신호특성을 비교하여 노이즈를 제거하는 SRPDA(Speed Related Partial Discharge Analysis)를 적용한 부분방전 진단 시스템의 개발 내용을 나타내었다. 또한 본 시스템은 광대역 방식의 장점인 빠른 검출 속도와 협대역 방식의 장점인 적은 노이즈의 영향의 장점을 취하는 동시에, 광대역 방식의 단점인 큰 노이즈 영향과 협대역 방식의 단점인 느린 진단 속도를 개선할 수 있는 하이브리드 방식을 채택하여, 기존 부분방전 진단 시스템의 신뢰성을 개선할 수 있을 것으로 사료된다.

In 1189's ZhongXiuZhengHuoJingShiZhengLeiBeiYongBenCao(重修政和經史證類備用本草), we took a look at the medicinal herbs that mentioned JoSeon(朝 鮮), GoRyeo(高麗), BaekJe(百濟), SinRa(新羅), DongIn(東人), DongHae(東海), YoDong(遼東), and BalHae(渤海). In the face of Korea's Oriental medicine's reality of having medical texts only after the 2nd half of the GoRyeo(高麗) Dynasty, this study will provide the basis of finding the origin of Indigenous Herbal Medical Science that was founded in the late-GoRyeo(高麗), early-JoSeon(朝鮮) period.
