The concept of 'wilful misconduct" was initally used in article 25 of the Warsaw Convention of 1929. The concept was defined in the Hague Protocol, 1955, as having the following two differing concepts: i) "with the intent to cause damage" and ii) "recklessly and with the knowledge that damage would probably result." The concepts contained in the Hague Protocol were used in various international Conventions on carriage by sea, such as Article 2(e) and Article 3(4) of the Protocol adopted at Brussels on Feb. 23, 1968 to amend the International Convention for the Unification of Certain Rules of Law relating to Bills of Lading, signed at Brussels, Aug. 25, 1929(Hague-Visby Rules), Article 13 of the Athens Convention relating to the Carriage of Passengers and their Luggage by Sea, Dec. 13. 1974, Article 4 of the Convention on Limitation of Liability for Maritime Claims, 1976, Article 8(1) of the U.N. Convention on the Carriage of Goods by Sea, 1978(Hamburg Rules) and Article 21 (1) of the U.N. Convention on International Multimodal Transport of Goods, Geneva, 1980. The same concepts were also adopted in Article 746, 789-2(1), 789-3(2) of the Korean Maritime Commercial Law, revised in 1991. As of yet, the legal system of Korean Private Law recognizes only the concepts of "Vorsatz" and "grobe Nachlassigkeit", as is the case with German Private Law. The problem is that the concepts in the Convention do not coincide precisely with the concepts of "Vorsatz" and "grobe Nachlassigkeit". The author has conducted a comparative analysis of the treatment of the concepts of wilful misconduct and its varied interpretations, that is, "with the intent to cause damage" and "recklessly and with the knowledge that damage would probably result" in the Anglo-American law and in the continental European law in the following manner: 1. Background in which the concept of wilful misconduct was introduced in the Warsaw Convention. 2. The concept of "dol" in French private law. 3. The concepts of "Vorsatz" and "grobe Nachlassigkeit" in Korean private law. 4. Analysis of the concept of wilful misconduct in Anglo-American case law. 5. Analysis of the cases interpreting the concepts of "with intent to cause damage" and "recklessly and with knowledge that damage would probably result" in various jurisdictions. 6. The need to incorporate the concepts of "with the intent to cause damage" and "recklessly and with the knowledge that damage would probably result." 7. Faute inexcusable in French private law. Based upon the comparative analysis, the author points out the difference between the concepts of "wilful misconduct" or "with the intent to cause damage" and "Vorsatz", and between the concepts of "recklessly and with the knowledge that damage would probably result" and "grobe Nachlassigkeit" in the Convention and that of the Korean Private Law system. Additionally, the author emphasizes the importance of the unification in the interpretation of the provisions of the Conventions world wide.

Background: Artificial insemination (AI) can serve as a powerful tool to the sheep owners for making rapid genetic progress of their flock. The AI in sheep is mostly performed using fresh semen with two reasons i) lambing rate following trans-cervical AI with frozen semen is limited by the inability of frozen-thawed sperm to transit the cervix and ii) the need of circumventing the cervical barrier through laparoscope aided intrauterine AI. Therefore, AI with frozen-thawed semen is not as widespread in sheep as it is in other domestic species. However, to get maximum benefits through the use of AI, frozen-thawed semen is a prerequisite because instead of high fertility, the short shelf life of fresh semen coupled with a limitation on the number of insemination doses achievable per unit time restricts the widespread use of individual sires. Therefore, in order to enhance lambing rate, a total of 240 trans-cervical artificial inseminations with frozen-thawed semen were performed in Bharat Merino ewes during autumn season either once in the evening (G-I, 10 h after onset of estrus, n = 100) or twice (G-II, 14 h and 22 h after onset of estrus, n = 140) i.e. once in the morning and again in the evening. Results: The pregnancy rate (proportion of pregnant ewes confirmed by ultrasonography at day 40) and lambing rate (proportion of ewes lambed) were higher in G-II as compared to G-I (26.4 vs 20% and 19.3 vs 10%, respectively). The difference in lambing rates was statistically (P < 0.05) significant. The depth of insemination within cervico-uterine tract had no significant effect on pregnancy and lambing rates. Conclusions: The results indicate that lambing rate in sheep following TCAI with frozen-thawed semen was significantly influenced by time of inseminations. Two inseminations after 14 and 22 h of onset of estrus enhanced the lambing rates of Bharat Merino sheep as compare to single insemination after 10 h of onset of estrus. The TCAI technique with frozen-thawed ram semen is promising and may serve as a valuable tool for genetic improvement of sheep breeds. Research efforts are going on worldwide to overcome the poor fertility following TCAI with frozen-thawed semen.

Among many open libraries under the rule of the Japanese imperialism, only the railroad library as the character of special library under the control of the Japanese Government General is remarkable for having opened its facilities to outsiders as well as the interior users. This study tries a) To look into what were the colonial background, aim and motive of the establishment of the railroad library under the Japanese rule, b) To analyze its activities and the change of its organization, c) And to find out its vestiges an the effects which it has on our country's library circles. The following are the result: A. The railroad library under the rule of the Japanese imperialism functioned as a public library by the outside book's circulation rather than the interior using. B. The outsiders were qualified to use it only when they got the joint guarantee for the city resident, which means that the o n.0, pportunity of the circulation was not free for the Koreans rather than the Japanese. C. From the aspect of collections, technical books such as natural science, and reference ones tended to be collected, and their whole composition was focused on the materials for the Japan-Korea identification scheme and development of the national spirit as the Japanese empire's subjects. D. In the respect of its organization, all the clerical employees, as well as the chief librarian were composed of the Japanese. Although the Koreans were in principle prohibited from working there, a few of them were employed as guard or servant as the China-Japan War was close to the end. E. The area of the outside book's, circulation service was expanded throughout the whole region along the railroad connecting Pusan with Manchuria. Such a service activity which contained several meanings, was tried by means of culture's books, circuit's books, train's books, hotel's books, mind's development books and reader's reading books etc. F. Such matters as the limitation on book circulating and the quantity of circulation book, the paid circulation and the partial restriction on free circulation mean the wartime system under the rule of the Japanese imperialism and also a n.0, ppeared as a factor of hampering the Koreans from getting accustomed to using library, which has affected them until now. G. The noticeable thing in the service activity is shown in attempting the diversified and positive way of service like free circulation in order to solidify the attitude of the Koreans toward war by organizing mind's development books as well as culture's books with the China-Japan War. H. On the other hand, it can not be passed over that the diversified service activity of the railroad library played a role of bridge in turning of today's library circles of ours to the modernization.

Objectives: Smokers who had failed to quit smoking were frequently reported that life stress mostly interrupted their abstention. Stress vulnerability model for smoking cessation has been considered, and most of contemporary smoking cessation programs help smokers develop coping strategies for stressful situations. This study aims to investigate the appropriate coping styles for stress of abstention from smoking. The result of investigating the relationship between abstention following smoking cessation program and coping styles would suggest useful information for those who want to stop smoking and health practitioners who help them. Methods: Participants were 69 smokers (62 males, 7 females) participated in a hospitalized smoking cessation program, whose mean age was 44.89 (SD=9.61). Participants took medical test and completed questionnaires and psychological tests including: Fagerstrom Test for Nicotine Dependence and Multidimensional Coping Scale. To identify participants' abstention, researchers followed them for 2 years. To identify whether abstained or not and encourage them to abstain, researchers called them on the telephone once a week for 3 months. After 3 months, they were contacted every other week till 6 months passed since they left smoking cessation program. And they were contacted once a month for other 18months. Researchers also contacted their family to identify their abstention. Data Mining Decision Tree was performed with 37 variables (13 variables for the coping styles and 24 smoking-related variables) by Answer Tree 3.0v Results: Forty four (63.8%) out of sixty nine for 2 weeks, 34 (49.3%) for 6 months, 25 (36.2%) abstained for 1 year, and 22 (31.9%) abstained for 2 years. Participants of this study abstained average of 286.77 days from smoking. Included variables of a Decision Tree model for this study were positive interpretation, emotional expression, self-criticism, restraint and emotional social support seeking. Decision Tree model showed that those (n=9) who did not interpret positively (<=7.5) and criticized themselves (>6.5) abstained 23 days only, while those (n=9) who interpreted positively (>7.5), expressed their emotion freely (>6.5), and sought social support actively (>11.5) abstained 730 days, till last day of the investigation. Conclusion: The results of this study showed that certain coping styles such as positive interpretation, emotional expression, self-criticism, restraint and emotional social support seeking were important factors for long-term abstention from smoking. These findings reiterate the role of stress for abstention from smoking and suggest a model of coping styles for successful abstention from smoking. Despite of limitation of this study, it might help smokers who want to stop smoking and health practitioners who help them.

Purpose: The most effective methods of harvesting, preparing, and injecting autologous fat grafts have been inconsistent and conflicting. With its limitation as resorption in fat grafting, handling various techniques affect adipocyte survival, and is crucial to optimizing its long-term survival. To improve graft survival, re-implantation of cryopreserved adipocytes was developed. In addition, adipocytes do not induce immune rejection in response to non-self lymphocytes in a mixed lymphocyte reaction. The purpose of this study is to analyze the changes in cryopreserved adipocytes so as to determine the most efficient long-term storage period, and to analyze the changes in cryopreserved allografted adipocytes so as to determine the efficacy of cryopreserved adipocytes allografting. Methods: Fat tissues were harvested from the inguinal and retroperitoneal fat pad of mice. After the centrifugation of the harvested fat tissues, they were disintegrated with collagenase. The adipocytes were obtained by centrifugation of the disintegrated fat tissues. The adipocytes were treated as follows: (1) They were examined for weight and then frozen at $-20^{\circ}C$(n=25). For four months, each five frozen samples were taken and examined for weight and histologic changes in the 1st week, the 1st month, the 2nd month, the 3rd month, and the 4th month, respectively. (2) The adipocytes were immediately frozen at $-20^{\circ}C$(n=125). For four months, five frozen samples were taken, and allografted in the same time period as above. Finally, for four months, five cryopreserved allografted adipocytes were taken and examined for histologic changes in the same time period as above. Results: (1) Significant weight changes and histologic findings with inflammatory and destructive changes were observed in the cryopreserved adipocytes in three months. (2) Significant fat necrotic changes in the histologic changes with Hematoxylin and eosin stain were observed in the cryopreserved allografted adipocytes since the first week, independent of the freezing period. Conclusion: The study results show that the adipocytes that were cryopreserved for more than three months underwent obvious weight reductions and necrotic changes, and the adipocytes that were allografted without freezing were viable for four months, but the cryopreserved allografted adipocytes had obvious necrotic changes since the first week regardless of the freezing period.

철과 킬레이트 화합물이 적도용승계에서 일차생산에 미치는 영향이 1989년 TOGA와 EPOCS 항해 기간 중 연구되었다. 식물플랑크톤 현존량의 변화와 철 결핍으로 인한 영 향은 광합성 전자전달계의 저해제인 DCM에 의한 생체형광의 변화를 이용하여 추정하였 다. 질소 신생산은 안정동위원소인 /SUP 15/N KNO$_3$의 흡수를 이용하여 측정하였다. 표층 질산염의 농도가 5 uM 이상인 용승해역에서는 대조군과 킬레이트화된 철 처리군 사이에 생체형광과 질산염 흡수능력에 유의성 있는 차이를 보였다. 그러나 CFC(세포형 광용량)에 있어서는 영양염에 의한 제한이 대조군과 처리군 사이에 유의성 있는 차이 가 나타나지 않았다. 표층 질산염 농도가 낮은 (0.5 uM 이하) 용승해역 바깥은 대조군 과 처리군 사이에 생체형광과 CFC 값에 유의성 있는 차이가 보이지 않았다. 적도 용승 계에서 1차생산과 질소 신생산은 철의 가용도에 의해 제한을 받는 것이 자명하다. 그 러나 CFC 값에 의하면 이 해역에 자생하는 식물플랑크톤의 생리작용은 철 결핍에 의한 영향을 받지않는 것으로 사료된다.

The purpose of this study was comparing the effectiveness in the topical applications of cyclosporine with that of steroid, the conventional and standard drug in the treatment of oral lichen planus. 21 patients with oral lichen planus were treated with cyclosporine (n=11) or steroid (n=10) by random allocations. They were recalled 2 weeks, 4 weeks, and 8 weeks after initial treatments. In each recall, the lesion size, clinical symptoms like pain or burning sensation, and side effects were evaluated. The differences of these measurements were compared and the effects of each drug were checked. In reticulation types, steroid showed higher effectivity than cyclosporine and this difference was significant statistically. But in erythema type lesions, either drug showed no significant recovery, statistically. However, the effect of cyclosporine was thought to be more effective. The pain of the lesions was significantly decreased by cyclosporine but not by steroid. The decrease of burning sensation was more dependant upon steroid than cyclosporine, but no statistical relationship could be found. There were no clinical side effects. There was limitation to draw in conclusion due to small pool of this study group. But with the results, this suggestion could be proposed that either drug might be superior to another in effectivity in a specific lesion type or patient symptom, so selection and usage of one drug in a specific case could be better than universal application of one drug in all cases.

비접지식 전기비저항 탐사는 땅에 접지전극을 설치하기 어려운 곳에서 전기비저항 탐사를 수행할 수 있는 방법으로 국내에서도 관심이 높아지고 있는 방법이다. 이 방법의 기본원리는 땅과 송수신 안테나의 용량결합(capacitive coupling)에 의하여 지하로 전류를 주입하고 이에 의한 전위차를 측정하여 자료를 획득하는 것이다. 본 연구에서는 쌍극자 및 단극 형태의 송수신 안테나를 일렬로 배치하는 방사 배열(radial array)에 대한 기하학적 상수를 유도하였다. 또한, 기존의 접지식 전기비저항 해석 알고리듬을 이용하여 비접지식 전기비저항 자료를 해석하기 위한 자료 전처리 및 변환 과정을 제시하였다. 즉, 획득된 탐사 자료를 기하학적 상수를 이용하여 일단 겉보기 비저항으로 변환한 후 쌍극자 배열이나 변형된 쌍극자 배열 자료로 보간 혹은 재샘플링함으로써 기존의 접지식 전기비저항 역산 알고리듬을 이용하여 해석하였는데, 동일 측선에서 수행한 접지식 및 비접지식 탐사 자료와 비교하여 그 타당성을 검증하였다. 비접지식 전기비저항 탐사법은 전류를 많이 주입할 수 없는 기기 상의 단점을 갖고 있음을 알 수 있었는데, 특히 전기비저항이 낮은 곳이나, 전기적 잡음이 심한 곳, 그리고 송수신 안테나의 접촉이 좋지 않은 지역에 적용함에 있어 세심한 주의가 요구된다. 그러나, 송수신 안테나를 일렬로 배열하여 견인함으로써 연속적으로 탐사 자료를 획득할 수 있고 전극 설치가 불가능한 지역에서 전기비저항 탐사를 수행할 수 있으므로, 신속하게 지하 천부에 대한 전기비저항 분포를 알고자 할 때 유용하게 쓰일 것으로 생각된다.
