  • The wind stress distribution over the East Sea of Korea was obtained from the shipboard observations of the Fisheries Research and Development Agency along the serial observation lines. These monthly and annual mean wind stress distributions were put into the simplified interface model which describes the latitudinal variations of the upper-layer thickness as function of the curl of the wind stress. The observed variations of the surface, zonally averaged winds indeed caused the upper-layer flow convergent and divergent at the latitudes that produced a tone of thick upper-layer or a deep permanent thermocline and the shallower depth with divergence. Thus, the wind field contributes positively to maintain the almost time-independent distribution of the interface of 'saddle like' feature in north-south direction over the study area.

  • Plasma bubbles that occur in the equatorial F-region make up one of the most distinguishing phenomena in the ionosphere. Bubbles represent plasma depletions with respect to the background ionosphere, and are the major source of electron density irregularities in the equatorial F-region. Such bubbles are seen as plasma depletion holes (in situ satellite observations), vertical plumes (radar observations), and emission-depletion bands elongated in the north-south direction (optical observations). However, no technique can observe the whole three-dimensional structure of a bubble. Various aspects of bubbles identified using different techniques indicate that a bubble has a "shell" structure. This paper reviews the development of the concepts of "bubble" and "shell" in this context.

  • Annual and monthly pollock catches, CPUE and fishing grounds in the high seas of Bering Sea between 1984 and 1992 were analyzed for centroid distribution and bivariate ellipses of trawlers of South Korea, Japan, Poland and China. The catch amount differed by country as 56.1%, 21.7%, 20.4% and 1.8% were caught by Japan, Korea, Poland and China respectively. Japan recorded the highest mean CPUE at 5.7 ton/hour while it was 4.3 ton/hour for Poland, 3.9 ton/hour for Korea and 2.4 ton/hour for China. Cumulative catch varied by month, with the minimum of 137,000 ton in March and the maximum of 848,000 ton in December. Monthly mean of CPUE was the lowest in February (2.0 ton/hour) and the highest in November (6.3 ton/hour). The centroid distribution of monthly fishing ground was located at a southern spot ($56^{\circ}$ 05'N, $178^{\circ}$ 55'E) in January, and it moved anti-clockwise toward $56^{\circ}$ 37'N, $178^{\circ}$ 24'E in December. Fishing grounds were scattered more by the east-west direction than by the south-north direction. The fishing grounds were similar for Korean, Japanese and Polish trawlers, but Chinese trawlers that fished only from July to December showed distinctively different fishing grounds from the others.

  • In order to prepare the interchange between and the unification of North and South Korea, it is needed to establish the development direction of irrigation reservoirs and formulate technological and political directions for preparing effectively against the demand of agricultural countermeasure information like the analysis of rural comprehensive development projects and the present state of agricultural land of North Korea. The purpose of this research is to construct the database of agricultural productive infrastructures and analyze the present state of irrigation reservoirs of the Yeseong River Basin in North Korea using SPOT-5 satellite imagery. As a result of the research, we were able to not only design classification items but establish method and precedure for producing thematic maps related agricultural productive infrastructure without on-site survey by analyzing present condition related to agricultural water of the basin. And we intend to provide basic data for analyzing suitabile locations of irrigation reservoirs in the basin by performing basin extraction, volume evaluation of the existing reservoirs, scale cultivative lands, benefit area fo the reservoirs, and the existing agricultural water system. In addition, we were able to understand the problem and limit in constructing the database related agricultural productive facilities.

  • Objectives: The Qing Dynasty experienced a development in Yunqi even greater than in the Ming Dynasty. Popularization and universalization of Yunqi theory led to many books on the subject published, especially with weights on Warm Heat Disease and Pestilence, also giving birth to new Yunqi theories. A study into this development has a great significance in the study of the traditional medicine in Qing. Methods: The paper studies the Yunqi books published in the Qing dynasty to find out the unique characters of those books. To understand the direction which the Yunqi theory in the Qing period took, the paper also reviewed the positions of different groups, those who were favorable, those who compromised, and those who were unfavorable. Results: Four directions were taken by the study of Yunqi in the Qing period. First is the systemic study and composition of Neijing's chapter of Yunqi. This direction was taken by Liumaoxiu's NeiJingYunQiBingShi) and $N{\grave{e}}ijingyunqibiao$, Xuefuchen's Suwenyunqitushuo, Zhuenhua's Suwenyunqiqianshuo, an unknown person's Su wen yunqi chao, Weigeliu's Neijingqihuapian. The second direction is the study of Yunqi in relation with the Warm Heat Disease and Pestilence, which was taken by Mayin lin's Wuyunliuqiwenyifayuan, Lumaoxiu's Suwenyipianbìngshi, Litianchi's Shiyiwenbingqìyunzhengyan lun, and Wangxun's Cihangsanyuanfujifang. The third direction deals with a new Yunqi theory. The Fourthis the explanation of Yunqi in the form of Songs, which was taken by Wuqian's Yunqiyaojue, and Wengzao's Yunqiyaojue. Conclusions: Ludanchen published Yunqibian, and explained that Haizichouyinmaochen, which is the eclipse's south latitude, becomes Nanzheng, and Southern government, which is the eclipse's north latitude, becomes Northern government. Lumaoxiu revealed that the Liuqidasitian, founded by Wangpuzhuang, his great grandfather on the mother's side, is in alignment with the theory of Dashitian, used by Liushozhen, Lidongyuan, Zhudanxi, and Zhangjingyue. The representative figure in the favorable view of Yunqi in the Qing period is Wuyang, that of those who compromised is Fengzhaozhang, and that of opposition is Zhangzhuo.

  • In order to investigate the environmental properties of set net grounds located in the coastal waters of Yeosu. The current in the vicinity of set net grounds was observed by drogue and current meter in 1990 and 1992. The results obtained are summarized as follows: The direction of tidal current at the north enterance of Yeosu bay was southerly in ebb and northwesterly in flood without the distiction of the neap tide and the spring tide. In spring tide the maximum Velocity of the tidal current was 68 cm/sec in ebb and 66 cm/sec in flood. In neap tide the maximum velocity of the tidal current was 37 cm/sec in ebb and 35 cm/sec in flood. And so the direction of residual current was the south ward mainly and 21 cm/sec. The direction of tidal current at set net fishing grounds was southwesterly in ebb and westerly or northwesterly in flood. Regardless of the distinction of neap and spring. The maximum velocity of the current in spring tide was 50 cm/sec in ebb and 40 cm/sec in flood and that in neap was 28 cm/sec in ebb and 25 cm/sec in flood. In spring tide the speed vector along the major axis of semidiurnal tide component was three times as large as diurnal tide. In neap tide, however, the speed vector was about 50% less then that in spring tide, and the semidiurnal tide and diurnal tide were equal in the size of current ellipse and the direction of major axis. The sea area had a southwesterly residual current. 11 cm/sec in spring tide and 7 cm/sec in neap tide. According to the result of drogue tracking, the vicinity of set net fishing ground had a southerly residual current which formed in Yeosu Bay and a weak westerly residual current toward Dolsando from Namhedo. Therefore, set net fishing ground in coastal water of Yeosu was distributed in boundary of inner water which formed from Seamjin river and offshore water supplied from the vicinity of Sorido and Yochido.

  • This study focuses on the lessons and implications of Germany's measures for the social integration after the reunification, and especially the Germany's measure on labor reproduction for the economic stability of East Germany. This analysis indicates, whether South Korea is going to achieve gradual and peaceful reunification or absorb North Korea due to its sudden collapse, that the reunification, in any case, requires the social integration through economic stability of both North and South. In order to ensure national reconciliation, recovery of homogeneity, and establishment of identity for the economically stable social integration, the new integration of educational system is necessary. Especially, the objective of this study is to find the role and direction of vocational education for the stability of the North Korea's labor market and economic life in order to socially integrate South Koreans with its Northern counterparts. First of all, this study examined a priori example of the experiences during West Germany's social integration process, i.e. the vocational education promotion process for the social stability and economic life. It figured out the problem of vocational education for the integrity as well as analyzed the vocational education differences and integration promotion system between East & West Germany. Even though East and West Germany showed their disparities in each vocational education, they corroborated each other by finding one similar system such as bifurcation, which lead to the integration of the labor market and new vocational education policy for the economic stability. Despite the West Germany's support for the socio-economic integration, nevertheless, the East Germany's capacity turned out to be insufficient, which resulted in the failure of the policy. Based on above discussion, this study intended to suggest the efficient solutions of vocational education for the internal reunification of South and North Korea by promoting the independence and self-support of North Koreans and leading the stability of labor market and economic for the future reunification.

  • Not much is known about the factors of North Korean refugees willingness to report crime. Based on the survey of 800 North Korean refugees living in the metropolitan area of South Korea, this study examined the theoretical factors influencing North Korean refugees' willingness of reporting crime. Focusing on the legal cynicism, procedural justice, and the behavior of law theory, this research verified that procedural justice model is most important in explaining their willingness to report crime. Variables under procedural justice model(i.e., perceived fairness of the law, confidence in the law, and perceived necessity of the law) were significant in an expected direction. On the other hand, most of the hypotheses based on social conditions derived from the five types of stratification, morphology, culture, organization, and social control presented by Donald Black (1974) showed no significant effects on the intent to report crime among North Korean refugees. Implications for research and policies were discussed based on the findings.
