Superplasticizers(Melamine sulphonate, Naphthalene sulphonate) has been used to aid the placement of high quality, high strength concrete in other country. The purpose of this study was to examine the effect of superplasticizers in the manufacture of high quality concrete(especially durability). This paper describes the results of hydration, X-ray diffraction of cement paste and setting time, strength, drying shrinkage, freeze-thaw resistance of concretes by the use of admixtures(Melamine sulphonate, Naphthalene sulphonate, Lignosulphonate). As a result, superplasticizers(Naphthalene sulphonate, Melamine sulphonate) can be used at high dosage levels than Lignosulphonate without the problems of concrete.

COO(원산지 효과)에 대한 많은 기존의 연구들이 이루어졌음에도 불구하고, 대부분의 기존의 연구들은 주로 전자제품 등의 공산품을 중심으로 또한 선진국-고품질 제품, 개발도상국 - 저품질 제품의 틀 속에서 연구가 주로 이루어져 왔다. 또한, COO를 통한 전반적인 마케팅 전략의 수립보다는 마케팅 프로세스의 일부분에 COO가 미치는 영향을 연구한 단편적인 연구가 대부분이었다. 이에 본 연구에서는 기존 연구와는 달리 선진국인 미국과 일본 시장을 대상으로 한국의 고품질 농산품인 “고려인삼”의 마케팅 전략의 수립이라는 전체적 측면에서 COO에 대한 기존 이론들을 검토하고 이를 실증하였다. 연구의 결과 고려인삼은 미국과 일본시장 모두에서 원산지 효과가 있는 것으로 나타났다. 하지만, 시장 세분화를 위한 가설인 고연령 - 저학력의 사람들에게 원산지 효과가 보다 유용하다는 가설은 기각되었다. 이는 과거의 연구와는 달리 개발도상국-고품질 제품의 조합이라는 제품 특성 때문인 것으로 보인다. 또한, 마케팅 전술을 세우기 위한 특정 유통 경로가 원산지 효과에 영향을 미친다는 가설은 미국과 일본시장에서 모두 지지되었으며, 제품에 대한 정보 원천이 원산지 효과에 영향을 미친다는 가설은 미국에서만 지지되고 있음을 확인하였다. 또한, 이러한 결과를 바탕으로 토의 부분에서 한국의 고품질 농산품인 고려인삼의 효과적인 미국과 일본시장에서의 마케팅 전략을 제시하고 있다. Most of the previous studies concerning American or Japanese market have focused on the difference in COO effects between indigenous product mostly with positive COO effect and foreign products mostly with negative COO effect. and, the previous COO research has concerned with the electric home appliances like TV or automobiles while there has hardly been research concerning the COO effect and its application strategies on agricultural products. But, our exploratory research on the agricultural product extends the product categories regarding COO effects and our study is concerned with foreign product which has positive COO effects in American and Japanese market. We can observe that there exists the COO effect on ginseng in American and Japanese market. but we can find some results which are not consistent with the previous research - especially, in demographic factors of america and information source of Japan. We explain the reason of this results and suggest new strategy of COO. Also, we suggest the marketing process to make use of the COO effects, which can be applied various product categories.

Cadmium, a potent toxic metal, posses a serious environmental threat but the mechanism of its toxicity remains unclear. Also, cadmium is a known immunotoxic agent in animal studies and induces pathophysiological effects by modulating components of immune system. Cytokines are being increasingly recognized as essential mediators of normal and pathologic immune response. Cells of mononuclear phagocytic system are strategically located at portals of entry in humans and therefore may be particularly at risk for cadmium exposure through contaminated air, food, and drinking water. In the present study, we investigated the effect of cadmium cytotoxicity for the monocyte and expression of cytokine gene in the control and cadmium treated human monocytic cell lines using RT-PCR method. The results showed that cadmium inhibited cell proliferation at 0.1mM cadimium treated cells for 24 hours. The TNF-α mRNA was expressed in both control and cadmium treated cells but not IL-6 and IL-1β. The mRNA levels of TNF-αwere examined during 24 hours culture period, at different time points. The expression of TNF-αmRNA increased in both 0.01mM and 0.1mM cadmium treated cells, but did not show dose-response relationship. According to cadimium treated duration, expression of TNF-αmRNA was more decreased in 24 hours than 6 hours. The decreased levels of mRNA of TNF-α suggest that cadmium suppresses its production at the transcription level.

地方化時代의 到來로 高揚市는 많은 變化가 豫想되고 있다. 1980年부터 繼續的으로 論議되던 地方自治의 問題가 지금은 現實化되어 1991年 4月에는 基礎地方自治의 議會를 構成하고 6月에는 廣域自治團體의 議會를 構成하였고 머지않은 將來 에 地方自治團體의 長을 選出할 豫定이다. 앞으로 많은 施行錯誤가 있을 수 있겠으나 地方自治時代에 돌입한 것은 누구 도 否認 할 수 없는 사실이다. 1997年경의 住民構成은 1990年代初期의 高揚市에 居住하고 있던 原住民과 一山을 포함한 新高揚 開發地域에 90萬의 新 入住者로 구성될 것이며, 이러한 高揚市 住民構成의 變化는 地方自治에 커다란 衝擊要因으로 작용될 것이다. 新.原住民의 要求를 調和하는 問題는 여러 形態로 나타날 수 있으나 住民福祉라는 側面이 매우 강하게 대두될 것이다. 高揚市의 福祉活動은 生活保護者들을 위한 특수한 경우를 제외하고는 거의 전무한 상태이다. 地方自治制度가 어느정도 安定的인 국면으로 접어들면, 地域的 次元에서 市民 모두를 위한 福祉活動이 深度있게 展開되어야 할 것이다. 市行政機 關과 市議會는 兒童福祉, 婦女福祉, 老人福祉및 醫療福祉에 대한 現況울 把握하고 이에 대한 해결의 優先順位를 결정하 여 다가오는 人口의 增加에 따른 福祉需要를 충족시켜 나가야 할 것이다. 福祉需要에 대한 優先順位를 硏究者들이 제시하여 보면 託兒施設과 더불어 綜合病院施設을 擴充하여 市民들에게 奉仕 하는 태세를 體系化하여야 할 것이며 그밖에는 施設을 擴充하는 方式보다는 年齡과 性別 및 職業 등의 基準에 맞게 "프 로그램"을 積極的으로 開發하는 努力이 경주되어야 할 것이다. 그러으로써 量的인 意味에서 뿐만이 아니라 質的인 意味 에서 福祉活動을 展開할 수 있는 基盤을 造成할 수 있을 것이다. It is expected that Koyang City have lots of changes according to the emergence of Decentralization era. Nowdays local self-government has been realized since its disscussion in 1980. On april, 1991, the assembly of basic self-government was established, and the assembly of extensive self-government constructed on june, 1991. The chairman of local-government assembly is supposed to be elected in the new future. None can deny the beginning of local-government era inspite of potential trial and errors. Population structure in 1997 is expected to be composed of the existing civilians of Koyang City in early 1990's and about 0.90millions of new comers in new cities including llsan area, and he change of the city population will significant impacts on the self-government scheme of Koyang City. The problem to coordinate desires of existing civilians and that of new comers might be embodied in many kinds of aspects, but welfare-raising will be strengthed first of all. Existing welfare programme of Koyang City dosen't show any signigicant activities except the case of Green Card programme. It is desirable that whole-sideed welfare programme be perfomed by local levels in the stage of staionary self-government systems. Administrative institutions and assembly of city should survey and research the present situations of children welfare, female welfare, the old age welfare, and medical welfare, and decide their priorities to meet increasing desires coming from rapid increase of city-population. We, researchers, propose several outstanding problems by priority as follows; to expand medical institutions and public nursery schools accompanies by strenthening the attitude of government employees for public service, to develop various programmes in order to activate many exiting institutions more efficiently rather than to build new institutions needed, in consideration of ages, sex and occupations of their users. If these propositions accomplished the welfare programme will have cornerstone to enrich its activities as well as activities as well as enlarge it bounderies.

The tandem network composed of the existing circuits network and packets network will integrate into a single network after this. that is, the circuit-based services of PSTN/ NISDN will integrate into the packet-based tandem network by using the devices of Media Gateway etc. moreover, because it is possible to multiplex the connections assigned to each subscriber by using AAL2 switching function of ATM network, we can heighten the utilization efficiency of network. In this paper, we described the VoDSL using an ATM tandem network and the call admission/ departure control algorithm, and appeared the performance estimation for the numerical results of multiplexer with bit dropping.

We consider a step stress life testing which is deviced for a two-component parallel system with the considerable long life time. The purpose of this paper is to suggest an optimal time for changing the stress when the simple step stress life test is carried out. The life distribution is assumed as the ACBVE by Block and Basu(1974) and the expanded CE model is suggested for the bivariate case. The criterion for optimality is to minimize the variances of the maximum likelihood estimators of the mean life times under the normal stress.

Recently, simulated annealing algorithms have widely been applied to many structural optimization problems. In this paper, simulated annealing, boltzmann annealing, fast annealing and adaptive simulated annealing optimize truss structures for improving quality of objective functions and reducing number of function evaluations. These algorithms are classified by cooling schedule. In this paper, many parameters have been applied for ASA's cooling schedule. The influence of cooling schedule parameters on structural optimization obtained is discussed. In addition, cooling schedule of BA and ASA mixed is applied to 10 bar-truss structure.
