Two cases of primary small cell carcinoma of the ovary occurred. One was a case of 43-year-old woman associated with hypercalcemia and the other was a case of 40-year-old woman with pulmonary type. Ovarian small cell carcinoma of the hypercalcemic type have clinicopathological, immunohistochemical, ultrastructural, and flow cytometric features that from differ from those of small cell carcinomas of the pulmonary type. It is important for therapeutic reasons to distinguish these two types of ovarian tumors from each other and from a variety of malignant small cell tumors that ovary primarily or secondarily. So, we reported these cases with a brief review of the concerned literatures.

Compounds with an oxygen-oxygen single bond, are called peroxides, which undergo homolysis readily by heating or irradiation with light, because the oxygen-oxygen bond is weak. The formed products are radicals, which are short-lived and highly reactive. This property is used as initiator in radical chain reaction such as halogenation and many kinds of polymerization. Peroxides are one of the important oxidants and initiators. In this paper synthetic methods of peroxides and mechanisms are reviewed.

고시제도개혁의 시차적 접근

제도개혁을 위해 제도 내에 존재하는 목적과 수단간 인과관계를 논리적 연계만이 아니라 시간적 연계 하에서 파악해야 할 필요가 있다. 이 연구는 시차를 고려하는 동태적 시각에서 제도변화과정을 분석하기 위한 것이며, 그 사례로서 고시제도 개혁을 선정했다. 고시제도 개혁의 논리적 연계성과 시간적 동태성을 고려해 제도개혁의 성공을 위한 제도적 기반을 구축하고자 한다. 이는 고시제도개혁이 성공하기 위해서는 분명한 목표설정과 시간적 동태성의 고려가 중요하다는 점을 강조하기 위한 것이다. 고시제도 개혁은 제도설계의 주요 요인으로서 평가대상 지식영역 및 평가방법의 선정, 그리고 관련자들의 공감대 형성이 매우 중요하다. 평가대상 지식영역 및 평가방법은 제도의 성패뿐만 아니라 관련자들의 공감대 형성에도 상당한 영향을 미치기 때문이다. 고시제도 개혁을 성공적으로 추진하기 위한 초기 전략으로 ①문제 풀(pool)을 확대해 다양하고 객관적이며, 타당성 있는 문제를 보유해야 하고, ②수험대상자에게 제도변화에 대한 이해 및 홍보를 통해 제도변화에 따른 불이익을 최소화하고, ③수험대상자에게 공직적격성평가 문제의 유형과 실례를 사전에 공개하고, 또한 실전테스트를 통해 공직적격성평가 문제에 대한 의견수렴과정을 거쳐야 한다는 것이다. 그리고 이러한 초기 제도화과정을 거치고 나면 공무원의 교육훈련프로그램 및 일하는 방식의 전면적인 변화가 이루어져야 하며, 나아가 성과관리제도 및 인적자원관리체계의 구축이 필요하다. The causal relation between purpose and means which is implied in institution should be analyzed in terms of not only logical but also time interconnection in order to reform institution. This study is to analyze the process of institutional change with a dynamic perspective of time lag and employs the higher civil service examination as a case. The prerequisite of successful institutional reform is suggested by adopting both aspects of logical interconnection and time dynamics of the examination reform. This is to put an emphasis on considering the clear goal setting and time dynamics to have a successful institutional reform of the exam. The examination institutional reform regards knowledge sphere, the selection of evaluation method, and common belief of related people as the major factors of institutional design. The knowledge sphere and the selection of evaluation method influence not only the success and failure of institutional reform but also common belief of related people. The initial strategies for successful reform of the exam institution are: expanding the question pool, minimizing the disadvantages of exam preparation people resulting from the institutional change, and adopting the exam preparation people to the PSAT(Public Service Aptitude Test) by informing the question typology and cases in advance and by including their opinions on the questions. After institutionalizing the reform, the training program for public officials and the way of doing work should be changed to activate the effect of the reform. In addition, the performance management and human resource management systems should be established.

권요한,정해양 慶熙大學校 레이저 工學硏究所 1997 레이저공학 Vol.8 No.-

In this paper, we analyzed d. c. and microwave characteristics of GaAs-MESFET under laser illumination. We obtained the analytical expression of I-V characteristics of GaAs-MESFET for linear, knee and saturation regions by solving 2-dimensional Poisson's equation and compared calculated I-V curves with experimental data. The resulting I-V curves are in good agreement with experimental data. We also obtained the analytical expressions for the current gain cut-off frequency f?? and time constant for the linear and the knee region, respectively. It was predicted that the reduction of the current gain cut-off frequency and the increase time constant due to the photovoltaic effect under laser illumination.

An iterative method to determine the spatial size distribution of particles with simple polyhedral shapes from their projected images using extraction replicas has been developed. This method was applied to the size distributions of rod-shaped AIN particles and indicated that the lognormal distribution function described the spectral size distribution better than it did the distribution function of projected images.

Adzuki bean is sensitive to waterlogging stress. The overall study on the waterlogging stress is limited comparing to the study on the drought and any environmental stress. Therefore, the present study was conducted to investigate the changes in growth characteristics and the expression patterns of proteins at the 5-leaf stage periods of adzuki bean. The domestic cultivar, Arari (Miryang No. 8) was used to test the waterlogging stress. In the waterlogging treatment for 3 days, the plant height showed slightly decrease in the treatment at 3 days of waterlogging, but root fresh weight showed significantly changes at 3 days of the waterlogging treatment. Chlorophyll contents showed also significantly different at 3 days of waterlogging treatment compared to control the plants. The waterlogging stress gradually influenced the growth differences between the control and the treatment respectively. More than 350 pro- tein spots were identified on 2-D gels using an image analysis. Moreover, a total of 28 proteins were analyzed using LTQ-FT-ICR MS. Among these 28 proteins, a total of 18 proteins were up-regulated, and 10 proteins were down-regulated under waterlogging treatment. According to biological process, the most of the proteins were found to be involved in carbohydrate metabolism. Regarding the subcellular local- ization, most of the proteins were localized into chloroplasts in 5-leaf stage.

Cracking of the welded zone of high strength steel is one of the most important factors of weldability and many kinds of test methods have been proposed to study that. In this study, cold cracking susceptibility of welded zone for high strength steel (ABS EH32 steel) with the shielded metal are welding was investigated by the tensile restraint cracking test. Effects of diffects of diffusible hydrogen contents on root cracking, lower critical stress, crack initiation and fracture method, hardness distribution of the welded zone and fractography were mainly investigated. The wet electrodes with higher diffusible hydrogen contents showed lower the critical lower stress level than the dried ones. Because of the hydrogen embrittlement, the heat affected zone by using the wet electrodes had higher hardness values than that by using the dried ones. Fracture surface of the heat affected zone with the wet electrodes showed mainly brittle fracture (intergranular and cleavage) and that of the weld metal also showed partially that due to the hydrogen embrittlement.
