Near the Gapcheon, a new suburban city will be developed by the Ministry of Construction and Transportation, and a intracity highway will be constructed by Daejeon Metropolitan City. By these new plans, rapid disruption of environmental conditions near the Gapcheon will be anticipated. The new construction of the city and highway will raise a problem of environmental pollution and disruption of natural status of this area, and will have an adverse influence to environment of the Dunsan area and an industrial complex which are located at the downstream of the Gapcheon. This re-search was conducted on the Gapcheon area, Daejeon (Gasuwongyo to Wonchongyo) from August, 2001 to June, 2002 years. Microorganisms of Gapcheon are three forms, 17 varieties, 105 species, 58 geneva, 31 families, and totalled 125 taxa. And zooidal micro-organisms, one varieties, 16 species, 12 genera, eight families, and totalled 17 taxa. Hydrogen ion concentration of the stream is ranged from 7.10 to 9.98 with great variation, especially high below bridges of Gasuwongyo and Mannyeongyo. The clean water quality of the stream is still maintained very well due to dense distribution of diverse aqua-tic and swamp plants. Furthermore, species diversity of microorganisms in the stream does help to purify the quality of water, and to keep the health of the Gapcheon as natural. More environmentally controlled and continuous efforts to keep the Gapcheon in a natural status and to purify the quality of water should be made by Daejeon Metropolitan City Officials who ave now spending about 6G,5()0 million won for overall conservation plans of the stream (from 1999 to 2003 years).

Healthy Japan 21의 목적은 삶의 질을 향상시킴은 물론 노동가능 인구집단의 유병률을 줄이고 건강수명을 연장시키기 위하여, 21세기 모든 일본인들이 더욱 건강하고 행복한 삶을 향유할 수 있도록 국가사업을 활성화하는 것이다. 구체적 목적은 조기사망을 예방하고 건강생활을 향상하는 것으로, Healthy Japan 21의 전략적 기획과정에서 건강수명의 연장을 실현하기 위하여 2010년까지 달성되어야 하는 구체적인 목적들이 또한 제시되었다. 조기사망을 감소시키기 위하여 사고, 암, 자살, 심장병 감소의 중요성을 인식하고 9개의 주요 목표로 영양, 신체활동, 휴식과 이완, 금연, 절주, 구강보건, 당뇨병 예방, 심혈관계질환 예방, 암 예방을 설정하였다. 흡연, 알콜, 식사 그리고 운동과 같은 생활양식은 스트레스, 비만, 고혈압과 같은 위험요인 및 질병관리와 관련이 있으며, 위험요인은 암, 심장병, 구강질환의 발생과 밀접한 관련을 갖는다. 따라서 질병의 발생을 예방하기 위해서는 건강증진과 일차예방이 강조되어야 한다. 일차예방에 중점을 두기 위해서 우리는 전통적인 질병관리의 중점사항인 정기적인 건강검진을 통해 질병 조기발견을 노력을 게을리 하지 말아야 할 것이다. 아울러 의료비 감소, 병상에 있는 사람들의 감소, 사회세의 감소도 또한 달성되어야 하는 사업의 결과로 설정되어 있다. 가장 최근의 Healthy Japan 2000(1998-99)의 평가에 따르면 목표들의 15%가 달성되었거나 초과 달성된 것으로 나타났다. 이 중 아동과 청소년의 사망률의 경우, 1-14세 아동의 사망률은 1987년부터 26%가 감소되어 2000년도 목표인 인구 100,000명단 28명의 사망을 초과 달성한 것으로 평가되었다. Healthy Japan 21의 두 가지 주요 전략은 일반 인구집단을 위한 전략과 고위험 집단을 대상으로 하는 전략으로 구성된다. 개인의 건강한 생활양식으로의 변화를 포함한 우리의 건강증진 노력은 사람 중심으로 개인의 선택을 기반으로 하고 있다. 이러한 노력을 지원하기 위하여, 각 개인이 정보를 갖은 상태에서 올바른 선택을 할 수 있도록 적당량의 올바른 정보를 제공하는 것이 필수적이다. 이와 같은 일본의 건강증진계획은 2000년 3월에 Healthy Japan 21이 설립되었으며, 2000-2002년 사이 모든 현이 자신의 사업계획을 설정하였으며, 2001-2005년에는 약 반수 정도의 지방자치단체들이 자신들의 사업계획을 확정하였다. 건강증진을 이루는 중요한 수단은 파트너 쉽에 있다. 정부조직 뿐 아니라 건강보험회사, 보건의료서비스 제공자, 교육단체, 대중매체, 사기업, 봉사단체 등을 포함한 건강분야의 조직들은 자신들의 전문적 기술들을 한데 모아 서로 협력하여야 한다. 또 하나의 중요한 수단은 건강 지지적인 환경이다. 개인의 건강증진 노력을 체계화함으로써 지지적인 환경을 조성할 수 있다. Healthy Japan 21에 대한 평가는 2005년에 중간평가가, 2010에 최종평가가 있을 예정이다. 평가결과들은 이후에 진행될 사업의 향상을 위한 기준으로 활용될 예정이다.

This research assumes that abduction is so important as much as all the creative plausible reasoning to be based upon. We expect it to be deeply appreciated and be taught positively in school mathematics. We are noticing that every problem solving process must contain some steps of abduction and thus, we believe that those who are afraid of abduction cannot solve any newly faced problem. Upon these thoughts, we are looking into the middle school mathematics textbooks to see that how strongly various abductions are emphasized to solve problems in it. We modified types of abduction those were suggested by Eco(1983) or by Bettina Pedemonte, David Reid (2011) and investigated those books to see if, we may regard, various types of abduction be intended to be used to solve their problems. As a result of it, we found that more than 92% of the problems were not supposed to use creative abduction necessarily to solve it. And we interpret this as most authors of the textbooks have emphasis more on the capturing and understanding of basic knowledge of school mathematics rather than the creative reasoning through them. And we believe this need innovation, otherwise strong debates are necessary among the professionals of it.

Chu Hsi inherited the proposition of Cheng Yi, and it spent him over ten years to finish writing the works of Xi Ming Jie, thus, making the thought of "Li Yi Fen Shu" bethe explanatory model of Xi Ming, therefore, playing the role to determine the tone of Xi Ming. At first, the thought of "Li Yi Fen Shu is a concept to embody the ethical significance of Xi Ming. But in terms of all the discussion about "Li Yi Fen Shu" of Chu Hsi in his life, this proposition is not only for the ethical significance of Xi Ming, but also includes much more general philosophical significance, revealing the general and special relationship of things. The former is the narrow "Li Yi Fen Shu", but the latter is the generalized one. This article won't discuss the generalized one, and it will take the narrow one as the research object. In the past research in academic circles, some scholars thinks that the proposition of "Li Yi Fen Shu" accords with the aim of Xi Ming, some others don't think so. Contrary to both of the two views, this article thinks that there is some conformity and inconformity between the explanatory model of "Li Yi Fen Shu" of Chu Hsi and the aim of Xi Ming. In other words, Contributions and limitations coexist when Chu Hsi explains Xi Ming in the model of "Li Yi Fen Shu", and there is not only the development to the intention of Xi Ming, but alsothe far meaning away from the aim of Xi Ming.

Welded connectors of the cover plates, the transverse stiffeners of the plate girders, and the gusset plates of the plates girders or box girders, were selected as studying objects. A simplified method of drawing the S-N curves in these welded joints by a computer program without the direct fatigue tests was established. The plots on the S-N curve using the values from the practical fatigue tests were compared with the results from the method of the computer programming. The results of these studies are as follows. It appeared that the fatigue life by calculation method was a little less than the practical fatigue life from the actual tests. The latter values included both life $N_c$ of occurrence of initial crack $a_i$ and the life $N_p$ of propagation of critical crack. On the other hand, the former values included only the life $N_p$. Therefore, these results should be considered as justifiable ones. Since the difference between the two results was not significant, the results by calculation method should be in the conservation side when the safety of the structures was considered. Consequently, the results by calculation method should be applicable to the fracture fatigue design of structure. For reference, the same fatigue tests were performed with the specimens of 3 pieces in each case made of the low-strength steel, SS 41. The results went unexpected showing that the fatigue strength was lower in the case of low-strength steel. That is, in the case of the cover plate, the fatigue strength became slowly higher than the case of high-strength steel, SWS 50. That was observed when the maximum testing stress was higher than $14kg/mm^2$. In addition, in the case of the transverse stiffener, the fatique strength became rapidly higher than the case of SWS 50. That was observed when the maximum testing stress was lower than $31kg/mm^2$. It was thought that more such fatigue tests should be performed for more reliable results.

Recently public and finance SI (system integration) industry is called as 4D (difficult, dangerous, dirty, dreamless) industry because of low profit, overtime works and poor motivation of employees. Even some people think at SI industry to be a labor intensive industry instead of a high technology industry. The current study considers outside environmental change of SI industry as well as inside capability enhancement of SI companies. The study adopted action research method with the author's expertise and experiences as a head of a major SI company in Korea. The current research framework suggests 5 areas of profitability enhancement that offers propositions and implications. 5 areas of profitability enhancement are (1) policy improvement, (2) business portfolio innovation (3) sales capability reinforcement, (4) delivery capability reinforcement, and (5) cost management innovation. The five areas include 11 propositional factors and 21 implementation plans which were chosen from the profitability perspectives of SI companies.In order to successfully execute propositions and implementation plans of the framework, 3 years is needed and after 3 years profitability are expected to increase 10% higher than the current level. The framework, propositions and suggestions in this study are expected to offer a real contribution for SI companies that want to enhance competitiveness and profitability. Future extension of the current study to benchmarking the competitiveness and profitability between local companies and global companieswill bring a solid attention from industry and academics.

A field experiment was conducted on a recently reclaimed hillside land to investigate the effectiveness of newly formulated compound fertilizer (10-14-11) containing fused phosphate as phosphorus source. Winter barley was adopted as a crop and commercial compound fertilizer (22-22-11), triple superphosphate, and ordinary fused phosphate were compared with the new compound fertilizer. The result of present study is summarized as follows. 1. When viewed from the plant hight and dry matter yield observed at different growth stages, it was indicated that newly formulated compound fertilizer seemed to be more effective in late stage than early stage. 2. Grain yields were higher in the compound fertilizer plots compared to the triple superphosphate and fused phosphate plots. The yield was specially high in the newly formulated compound fertilizer plot. In this plot, the number of grain per panicle and the rate of maturity were higher than the other plots. 3. The amount of phosphorus uptake by plant in the newly formulated compound fertilizer was lower in early stage and higher in late stage. In this experiment, the magnesium and silica contained in fused phosphate did not influence the growth and yield of barley because the soil was relatively high in these components. 4. Because of the unprecedented severity of winter weather during the experiment, the result obtained in present study may not be generalized until some studies confirm present findings.

Xinxu(新序) was published in Korea by 1492. Among the existing editions, the editions that can confirm the realities are the collections of Keimyung University, the Korean Studies Central Research Institute, Kyonggi University, Hujodang(後彫堂), and the National Assembly Library of Japan. The Keimyung University's precious book is the 'first published book', and the old book is the 'later published book' which covers pages 69-70 and 71-72 of the first published book. It is the 'later published book' that has the same side inscribed. The second books, the Central Research Institute of Korea Studies and the Kyonggi University Collection are the first published books, and the Hujodang and the National Assembly Library of Japan are on pages 9-10, 63-64, 87-88, 107-108. The corresponding side is the 'later published book'. Comparing the editions, it can be concluded that the existing editions of the previous editions have been withdrawn two times, and in the latter editions, the existing editions of four editions can also be confirmed to have been edited three times. In this paper, the literature based on the existing editions was studied and features of the Korean edition were presented. First, we examine the types of paragraphs. In principle, the text is composed of '11 lines and 18 characters', but on the actual version, the number of characters is shown in the table. In the Korean edition of the Joseon dynasty, a blank space appears in the original text. The erroneous letter in the Joseon book was identified the reason for the error was explained in detail.

With starting the industry of automobiles, railroads and mining, the legal principle of "erlaubtes Risiko" that began as a means of maintaining the revitalized world for the cause of social utility has interpreted as a system of negligence theory in the precedent while it has gained academic recognition. Yet in aircraft operation, which is one area of high technology, CAT which can be the cause of some accidents or events or thunderstorm with turbulence is an abnormal meteorological phenomenon with frequent change that cannot be monitored perfectly just as some patient with unstable condition and that cannot be ascertained about not only the possibility of its happening but also the degree of how big the accident is. Yet the use of jet current which has the possibility of CAT can be an act of high social utility where we not only drastically cut down on time fuel also guarantee the arrival and departure on schedule when landing in airports that have thunderstorm which does not appear as fatal risk. Although we could take some measures where we can predict and avoid the potential risk, easing the regular duty of care is necessary by applying the legal principles of permitted risk concerning the incidents and accidents caused by operating in areas with the risk of turbulence or CAT with the low probability by the reason of social utility.
