In fisheries financing before the liberation of Korea, the accommodation of funds through modern monetary facilities was hardly benefited to most of small-scale Korean fishermen except Japanese fishermen living in Korea and some large-scale Korean fishermen. In fact, since Korean economy was only in the beginning stage of capitalism free from natural economy in the end of Yi Dynasty, it was natural that the supply of funds should be lacked. But after the opening of ports in Korea, the external shapes in Korean society were slowly changed according as heteronomous modernization was pushed forward by means of western capitalism and the intentional invasion of Japanese was gradually weighed. Thus all kinds of fishing equipments and technique were developed by dint of modernization, and modern monetary facilities also came into being. But most of Korean fishermen were hardly benefited by modern monetary facilities. Fishermen who were faced with destitution of funds were forced to rely upon high interest loans in order to make a living or maintain fisheries, and they were severely exploited by usurers. The situation was the same in the period of Japanese imperialism. Japanese felt the necessity of advancement of Korean fisheries and established fisheries institution suitable for all kinds of colonial fisheries policy toward Korea so that they could build up the foundation according to the development of capitalism and carry out the Russo-Japanese War and the Sino-Japanese War. There were a series of bottlenecks in financing on account of the deficiency of fisheries institution in the beginning of Japanese imperialism, but the financial pressure was lightened because the arrangement of institution greatly contributed to the smoothness of fisheries financing in the latter part of it. Despite such improvement of financing, the benefit of funds could not equally reach to all the fishermen. It only reached to Japanese fishermen living in Korea and some large scale Korean fishermen. Thus most of korean fishermen could not free themselves from destitution of financing and the pressure of high interest loans. This phenomenon took place because Korean fisheries had the antinomic characteristics that financial restriction was excessive owing to the industrial speciality of fisheries, on the other hand there was a large financial demand in fisheries in the character of industry.

Purpose: Fractures of the mandibular condyle accounts for 15% to 30% of all the mandibular fractures and lots of complications are reported. Among these complications, condylar resorption is the most important one to be taken into account. The purpose of this study is evaluating condylar resorption pattern in relation to extracorporeal fixation technique. Patients & methods: Thirty four patients with 42 mandibular condylar fractures were retrospectively examined with an average follow-up of 18.5 months (6-66 months). Male/female ratio is 27 males (7 bilateral cases) and 7 females (1 bilateral case). Applicated surgical techniques were extracorporeal fixation via submandibular approach and extracorporeal fixation via intraoral approach. We compared radiographic views of post-operative periods with that of most long term follow up in 34 operated sites respectively. Result: There were 2 generalized condylar resorption sites and 3 partial resorption sites with clinical implications. Others (29 joints) showed good healing or satisfactory adaptive state of temporomandibular joints clinically. Radiologically, signs of partial condylar resorption and/or osteoarthrosis were diagnosed in 11 patients. But, 8 out of the 11 patients didn't show significant clinical symptoms, which means successful adaptive remodeling of the surgically located condylar head. Conclusion: From the above results, intentional ramal osteotomy, temporary detachment of the fractured condyle and extracorporeal fixation technique seems to be effective and useful in those cases of condylar fractures in which reduction of the dislocated condyle is very difficult or virtually impossible.

This study investigated the effects of nursing in formation given verbally and a booklet on the knowledge, Physical symptoms, anxiety and daily activities of patients recovering from open heart surgery from just before discharge to six weeks after discharge. The convenience sample was of patients who had undergone open heart surgery in Seoul National University Hospital. The first 25 patients who agreed to participate in the study became the control group. They did not receive the intentional information but the usual nursing care. The next 28 patients became the experimental group who received a booklet about their post-discharge care which was discussed with them by the researcher before discharge. This study used a non equivalent control group non - synchronized quasiexperimental design. The tools included a 30 item knowledge scale, a 9 item physical symptom scale, Spielberger's state anxiety scale, and a 28 item daily activity scale. The instruments were applied before discharge and at two and six weeks after discharge. For data analysis, frequency, t-test, Pearson's Correlational Coefficient and Cronbach's $\alpha$ were used. The results were as follows : 1. Information given through the booklet was effective in increasing the knowledge of patients recovering from open heart surgery. The experimental group's knowledge was higher at 2 weeks after discharge than prior to discharge (P＜0.05). 2. There was no significant difference in physical symptoms between the two groups at two and six weeks after discharge. 3. Information given through the booklet was effective in decreasing the State Anxiety two weeks after discharge (P＜0.001) but at six weeks after discharge, there was no significant difference in anxiety between the control and the experimental groups. 4. There was no significant difference in daily activity between the two groups at two and six weeks after discharge. 5. There was a negative correlation between knowledge at discharge and at 2 weeks and anxiety at 2 weeks after discharge. There was a positive correlation between knowledge at discharge and daily activity at 2 weeks after discharge. There was a negative correlation between knowledge at 2 weeks and Physical symptom at 6 weeks after discharge.

디자인의 기본 요소인 선을 활용하여 금속조형물을 시각적으로 완성하기 위해 시작된 본 연구는 선의 다양한 특징과 개념을 살펴보고 선행된 연구 중에서, 선을 중심으로 진행된 작품연구들을 통해 선의 조형적 아름다움을 알아보았다. 그 결과 선의 조형적 해석은 크게 선의 굵기와 선의 장단에 의한 의도적 표현으로 진행됨을 알 수 있었다. 선행 연구들을 바탕으로 연구자는 기존의 선의 조형적 표현에서 벗어나 시각적으로 자유로우면서도 미적 아름다움을 함께 느낄 수 있는 금속조형물을 얻기 위해 적동판과 인청동선 용접을 활용하여 선의 변형과 반복으로 하나의 패턴을 완성하고 이를 통해 작품으로 연계하였다. 그 결과 선의 면적인 표현은 물론 전체적 형태의 입체감과 속도감, 통일감을 함께 느낄 수 있었다. 앞으로도 선의 조형적 해석은 더 많이 연구되어야 할 것이며, 더 나아가 선의 표현을 통한 감성적, 내재적 아름다움에 대한 다양한 연구가 계속 되어야 할 것이다.

This study examines the examples and changes of wooden member terms in Yeonggeon-euigwe(營建儀軌) in the era of Joseon Dynasty. As a result of examining examples, about 240 wood member terms were found on the basis of phonetic value and examples different from today's term use were also confirmed. Wood member terms were derived in variety and synonym and different style, that is, coexistence or transition of several notations as the term indicating the same member was found. Derivation of detail terms has the characteristic increasing on the basis of morpheme and formation of different notation followed Chinese notation or was caused by complex coinage features like a coined word of Korea by the meaning of a word and borrowed character notation borrowing sound and it is also related to the specificity of that time which had dual language system. The typical examples without different style for long were pillar, rafter, door and window. Examples with active generation and selection of different styles included beam, capital and bracket-system terms. Different styles were caused by the combination of several notations including borrowed character in the process of Chinese character notation borrowing sound, Korean unique character emphasizing and limiting combination of 木 (wood) with side of character and Chinese. Period showing remarkable change of example notation was the compilation of ${\ll}$the Hwa-Sung-Sung-Euk-Eui-Gue${\gg}$ 華城城役儀軌. ${\ll}$the Hwa-Sung-Sung-Euk-Eui-Gue${\gg}$ is the representative type uigwe made by printed type not by handicraft. Printing by type accompanies unification of the shape of a character necessarily and it was considered that it resulted in the unification of character of different style, the number of strokes and minute difference of strokes, and it was interpreted that common use of intentional notation with the unification of the shape of a character was achieved.

The purpose of this study was to examine changes in the rate of occurrence of challenging behaviors in young children according to their increase in age. The study is based on the responses of teachers in child care centers(N=246). They were asked which 38 types of challenging behavior occur most among ages 2, 3, 4, or 5 in young children's classrooms. The major results of this study were as follows. First, the occurrence rates of young children's challenging behaviors were classified into 5 clusters; decreased(Cluster 1, Cluster 2, Cluster 3), maintained(Cluster 4), or increased(Cluster 5) according to increases in their respective ages. Second, the behaviors such as throwing tantrums and biting, evident in Cluster 1, decreased very rapidly from a very high occurrence rate by age 3. The classroom culture maladjustment behaviors such as running aimlessly around the classroom and shouting, apparent in Cluster 2, had decreased rapidly from a high occurrence rate by age 4. The intentional classroom disruptive behaviors such as dropping objects to create noise and the peer culture maladjustment behaviors studied in Cluster 3 decreased gradually from a rate of medium occurrence by age 5. These results revealed the discontinuity which a few young children exhibit. Third, hurting others, observed in Cluster 4 maintained a low occurrence rate from age 2 until age 5. Using inappropriate language and threatening others in Cluster 5 increased gradually from a low occurrence at 2 to a high rate of occurrence at age 5. By carefully examining the change of young children's challenging behaviors on the basis of objective data in terms of the continuity/discontinuity and increased/decreased rate of diverse challenging behaviors, we will be better able help teachers and parents to plan the instruction, prevention and intervention of young children's challenging behaviors.

Purpose: Some advanced countries have reported annual statistics for poisoning based on data from poison control centers. This study was conducted to propose a baseline format and statistics of poisoning in Korea from a national representative database. Methods: This study was a retrospective analysis of poisoning patients based on data from an emergency department (ED) based injury in-depth surveillance project by the Korea Centers for Disease Control and Prevention in 2016. Bite or sting injuries were not included. Variables related to poisoning were summarized using a similar format as the National Poison Data System in the United States. Results: A total of 7,820 poisoning patients presented to 23 EDs. Adults ${\geq}20$ years accounted for 84% of the population, while the proportion of intentional poisoning was 59.4%. The most common poisoning substances were therapeutic drugs (45%), gas (21%), pesticides (15%), and artificial toxic substances (13%). Overall, 34.5% of patients were admitted for further treatment. The mortality was 3.2% (248 cases), and the most common causative substances were carbon monoxide, glyphosate, and paraquat, in order. Conclusion: This study showed the recent status of poisoning in Korea. However, a comprehensive poisoning registry based on poison control centers may be required to provide more accurate national statistics in the future.

InSAR (Interferometric SAR) 기법을 이용한 DEM 추출은 두 SAR 영상의 정합, 간섭도 생성, 위상 필터링, 위상 unwrapping, 고도변환, 좌표계 변환 등 매우 복잡한 단계를 필요로 한다. 본 연구에서는 unwrapped 위상을 고도값으로 변환하는 과정에 대한 정밀도 향상을 위한 알고리즘을 개발하였다. 개발된 알고리즘은 지구타원체를 고려하여 수정된 ambiguity 방법, Schw$\ddot{a}$bisch 방법과 더불어 두 SAR 자료의 궤도가 평행하지 않을 때 발생하는 오차를 현저히 줄일 수 있는 개선된 ambiguity 방법이다. JERS-1 궤도를 이용한 알고리즘 성능 분석을 통해 기존 ambiguity 알고리즘은 두 개의 SAR 영상 궤도가 평행하지 않은 경우, 간섭위상의 고도변환 과정 중에 약 40 m 이상의 오차가 발생할 수 있음을 확인하였다. 개발된 알고리즘은 JERS-1과 같은 위성궤도의 불안정 또는 ERS2-ENVISAT Cross-InSAR를 위한 궤도 제어 등 다양한 원인에 의해 발생할 수 있는 평행하지 않는 두 위성 궤도 자료의 간섭쌍을 이용한 정밀 InSAR DEM 생성에 매우 효과적으로 활용될 수 있다.

This study aims to describe actual condition of residents' involvement of Sk$\"{a}$rk$\"{a}$ll ecovillage in Sweden by in-depth interviews with five residents. This study, hopefully, could contribute to offer useful information for forming ecovillage, as well as awakening about ecovillage movement to the public in Korea. The interviews were fulfilled during spring of 2010 in G$\"{o}$teborg and Sk$\"{a}$rk$\"{a}$ll ecovillage in Sweden. The results are as follows: 1) In terms of overall residents' involvement by self-evaluation everybody agrees with that residents' involvement was quite excellent during forming stage of the village, while it has been notably decreased now in running stage. It reveals there is a gap between ideology and reality. 2) Concerning decision making method, they use majority decision instead of consensus, since only 9 households of 20 are residing there all year around, it is hardly possible to assemble all the residents in the meeting. In Accordance with problematic conflicts in the village recently, development of socialization with others and education of communication skill for residents probably could be helpful to resolve conflicts among residents in long term. 3) In terms of evaluation of ecovillage movement in Sk$\"{a}$rk$\"{a}$ll ecovillage, it is the fact that many residents live less self-sufficiently, more energy consumed than the ideology pursuits. Also, they live with close connections with conventional society. Nevertheless, the efforts they are willing to practice 3R principles (Recycle, Reuse, Reduction) have to be highly respected, if we consider its educational influence to environmental movement for the conventional society.
