To find out the relationships between the changes of soil chemical properties due to submergence and paddy rice yield, a laboratory and 9 field experiments on 9 soil series were carried out. From the field experiments, relative yields of no fertilizer yield to maximum yield were widely distrbuted from 54 to 76, although the correlation between no fertilizer yields and maximum yields was significant. Among the chemical ingredients of submerged soil, $NH_4-N$ only showed significant correlation with no fertilizer yields. From the laboratory experiments, pH were much increased in the soils high in no fertilizer yield than the others. There were no significant correlation between $NH_4-N$ contents of submerged soils and organic matters of dry soils. Soils low in available $P_2O_5$, low in organic matter, and high in clay of dry soil were negligible in increments of available $P_2O_5$ due to submergence, and efficiency of phosphorous fertilizer in those soils were remarkable. Soils extremely high in available $SiO_2$ of dry sail decreased in available $SiO_2$ due to submergence.

The precursor polyimide of the photoreactive polyimides(PI-SP6 and PI-SP12) was prepared from a derivative of 2, 2, 2-trifluoroethane dianhydride and 3,3'-dihydroxy-4,4'-diaminobiphenyl. PI-SP6 and PI-SP12 were then prepared by the polymer reactions of the precursor polyimide with photoreactive 2-styrylpyridine alkylene (hexylene and dodecylene) derivatives, respectively. The photoreactive polymers were soluble in organic solvents. The polymers showed the initial decomposition temperatures around $350^{\circ}C$. The glass transition temperatures of PI-SP6 and PI-SP12 were found to be $130^{\circ}C$ and $85^{\circ}C$, respectively. This result means that the latter polymer is more flexible than the former polymer. Their transmittance in the film state was 90% at $250^{\circ}C$, which indicates that the photosensitive polyimides with thermal stability have high optical transparency even at the high temperature. The respective dichroic ratios of PI-SP6 and PI-SP12 were found to be 0.01 and 0.03 at an exposure energy of $1.5\;J/cm^2$. This result suggests that the latter polymer with larger flexibility compared to the former polymer is more effective for the photoalignment.

The need and rationale for public participation in science and technology is widely acknowledged in academic communities and policy circles. In addition to institutionalized forms of participation, some STS researchers have paid attention to spontaneous forms of public participation, particularly with regard to social movement. This paper aims to explore a new form of public participation, which had been relatively neglected in STS studies. For this purpose, in this paper we examine environmental health issues and cumulative trauma disorders (CTDs) debates as examples of doing "undone science" in Korea. Our focus will be specifically on how environmental organizations and trade unions have both succeeded in making those issues as research and policy agenda for both scientific community and policy makers. In a concluding section, a couple of suggestions for further research are proposed.

신태인 수위관측소는 동진강 본류에 위치하고 있으며 이 지점의 유역면적은 $218.0km^2$이고 하구로부터 19.0km 떨어져 있다. 이 지점은 하류에 위치한 동진제수문의 영향을 받는 곳에 설치된 수위관측소이다. 신태인 수위관측소에서 하류로 약 9km 지점에 부량 수위관측소가 있으며 이 지점에서 약 300m 하류에 동진제수문이 설치되어 운영되고 있다. 이 수위관측소는 하류의 동진제수문의 영향을 받고 있는 상황에서 수위-유량곡선이 개발되어 운영되고 있으며 수위-유량곡선은 저류와 방류로 구분되어 있다. 이들 관측소가 속해 있는 동진강에서 유출되는 유량은 새만금 간척사업지구내의 새만금호로 유입되기 때문에 중요하다. 신태인 수위관측소 지점의 유량측정은 1997년부터 2003년까지 실시되었다. 1999년부터 이 지점의 수위-유량곡선을 동진제수문의 개폐여부에 따라서 저류와 방류로 구분하여 수위-유량곡선을 제시하였다. 이 때 수문의 개폐여부는 동진제수문의 관리 대장을 참조하여 단순하게 구분하였다. 개방여부의 정도가 상류의 신태인 수위관측소에 영향을 미치기 때문에 이를 반영된 수위-유량곡선의 개발이 쉽지 않으며 실제 신태인 수위관측소에 관측된 수위에 따른 유량의 분포가 산포되어 있는 상황이다. 특히 평수위 이하에서 더 심한 것으로 나타났다. 이런 상황에서 단일 수위-유량곡선을 개발하여 적용하는 경우에 오차가 심한 것으로 나타나 있으며 실제 상황에서 저류와 방류로 구분하여 개발된 수위-유량곡선을 적용하는데 한계가 있다. 이를 극복하기 위해 동진제수문의 상류 약 300m 지점에 부량 수위관측소가 설치되어 있는데 이 지점의 수위관측소의 수위를 고려하여 부량 지점 수위와 신태인 지점 수위와 유량의 상관성을 분석하였다. 그리고 신태인 지점의 수위-유량곡선을 저류와 방류로 구분한 경우와 통합한 경우의 수위-유량곡선식을 비교하였다. 이 지점은 하류 수문의 영향을 받기 때문에 하류의 조위 등으로 영향을 받는 경우에 종종 사용되는 지수형 다중 회귀식을 적용하여 수위-유량곡선을 제시 하였으며 그 결과를 실측값과 비교한 결과, 상관계수가 양호하게 평가되었다.

The e-Learning quality assurance is a part of responsibility for education in latest information age, and should be understood as a basic direction for qualitative enhancement rather than quantifiable expansion. In such a context, this study sought to survey latest trends of e-Learning quality assurance activities deployed around overseas countries, so that it could give possible implications on how to plan and perform e-Learning quality assurance in Korea. So, this study focused on surveying actual conditions, coverage, target and useful indices of e-Learning quality assurance activities deployed by 9 institutions across 5 countries, and characterizing those activities across 5 countries. As a result, this study could find out its implications such as acquisition of various resources available for e-Learning, nationwide consolidation of e-Learning quality assurance activities, development of specialists in e-Learning quality assurance, and choice and focus for e-Learning quality assurance system. In other words, it was found that e-Learning quality assurance should be approached from nationwide standpoint in the interest of better educational quality, rather than from viewpoint of task.

Whether the engineering department of universities employs ideal usage of e-learning or not needs to be investigated as many engineering departments diversify the use of the e-learning elements for educational purpose. Applying the teaching and learning methods and characteristics would lead to better strategies which are applied to development of contents and deployment of the e-learning courses. This study examines the characteristics and approaches of the usage of e-learning elements used by some instructors who use multimedia contents in offline teaching and learning environment. The results of this study shows that the e-learning elements assist the face-to-face course and the interactions are manifested in the classroom rather than in online setting. Lecture, hands-on-practice, simulation, and PBL(Problem-based learning) are turned out to be the major teaching and learning methods. This study signifies the need for use of various teaching and learning methods by the instructors and provision of PBL environment.

Congenital thyroid dysgenesis including agenesis, hypoplasia and ectopia is the predominant cause of permanent hypothyroidism. Of these, two thirds are due to an ectopic thyroid and about one third to complete thyroid agensis. From Jan. 1981 to Dec. 1992, authors experienced the 9 cases of congenital thyroid dysgenesis. Aberrent thyroid was 4 cases (44.4%), thyroid hemiagenesis with aberrent thyroid was 3 cases(33.3%) and thyroid hemiagenesis was 2 cases(22.2%). The most predominant site of aberrent thyroid is the base of tongue(85.7%). 7 patients(77.8%) revealed euthyroidism and among them, 4 patients showed elevated TSH level. Hypothyroidism was 2 patients (22.2%). 7 cases responded to thyroid suppressive therapy. 2 cases of lingual thyroid which did not responed to thyroid suppressive therapy underwent surgery and they have placed on thyroid suppressive therapy postoperatively.

This research reviews the education welfare priority support project and analyzes its policy from the welfare-state perspective. This study evaluates the policy contents, overall procedures, and the changes in the perspectives of the project in accordance with the political power changes in the government, and illuminates future directions. For this, the research infers desirable typology of the welfare state, and analogizes the budget, the target population, key issues and delivery systems of the education welfare priority support project. Education welfare priority support project still remains to follow a selective and hierarchical business format, despite the legally stated initiatives, growing budget, and the expansion of the operation which has been governed by the policy makers. Particularly, the state of this project, and examine whether or not it has been distorted by the governmental emphasis on the educational outcomes and performance should continuously be examined as a future direction of the research. Finally, the study suggests several recommendations for the desirable anchorage of the project within the framework of being a prospective welfare state.
