그동안의 전력증강은 창의성과 기술에 의한 것이 아니라 숫자에 의한 전력증강 형태였으며, 우선순위도 없었다. 기술개발정책이 실종된채 국방부 산하에 창의적인 전문집단을 육성하려는 노력이 거의 없었다. 이에 따라 우리의 국방기술은 80년대 이후 답보상태이며, 이의 탈피를 위해서는 창의적인 전문집단의 육성과 미래지향적인 견해를 거침없이 제안할수 있는 정책적 배려가 절실히 요구된다

The purpose of this study is to examine the impact of teacher and family interaction on behavior problems and social skills of children with autism spectrum disorder. Survey method was performed with 147 pair samples of a teacher and parents of a child with autism to analyze the influence toward behavior problems and social skills. Samples have been classified into three groups such as the high group in which there exists high interaction level in both teacher and family, middle group in which there exists high interaction level in either teacher or family and low group in which there exists low interaction level in both teacher and family. The results show that the correlation between teacher interaction and social skill of autism children is significant and the level of social skills of high interaction group is higher than that of the middle and low interaction group.

This research aims to verify the moderating effect of sports activity satisfaction in the relationship between adolescents' communication skills and positive self-concept within peer group. To achieve this purpose, this study extracted 250 samples from five boys high schools in Gyeonggi-do, and used survey of 232 students for actual analysis excluding the surveys with unfaithful answer or double entry. Questionnaire was used as a tool for collecting data and conducted frequency analysis, correlation analysis and moderator regression analysis to analyze the collected data. This study drew the following results. It was identified that sub-factors of sports activity satisfaction as social, physical, environmental and educational satisfaction have the moderating effect in the relationship between adolescents' communication skills and social self-concept with peer group. In other words, communication skills within adolescents' peer group play an important role in improving positive self-concept, but when sports activity satisfaction put as a moderating variable, adolescents' positive self-concept would be more improved.

일본의 공정취인위원회는 지난 1977년부터 일본 경제에서 큰 비중을 차지하고 있는 6대 대규모기업집단에 대한 기업집단 내의 소유지배관계, 자본$\cdot$인적 및 상품에 대한 내부거래 현황, 그리고 대규모사업추진에 따른 상호 협력관계 등 멤버기업간의 결합 실태를 조사하여 왔다. 이 글은 공정취인위원회가 지난 1996년 1월부터 1997년 6월 30일간에 결산기가 도래된 기업을 대상으로 한 제6차 경영행태 조사의 결과를 요약$\cdot$분석하여 일본 공정취인협회가 발간한 $\lceil$공정취인$\rfloor$(1998년 12월호)지에 게재한 것은 전문 번역 게재한 것이다. 우리나라에서도 대규모기업집단의 선단식 경영에 대한 폐해(물론 장점도 있지만)와 공정거래 위원회의 부당한 내부거래의 제재에 대한 논란이 이루어지고 있기 때문에 양국의 재벌급 기업집단의 경영 형태를 비교$\cdot$검토함으로써 정책 운용에 참고가 될 수 있도록 하였다.

교통의 발달 및 빈번한 문화와 정보의 교류는 옥외 recreation 활동 참여의 다양한 인종적 구성을 가져왔다. 이 연구의 목적은 옥외 recreation 활동의 하나인 스키장에서 이용 밀도에 대한 선호도를 문화·인종간의 혼잡규범적 차이로서 해석하는데 있다. 한국의 용평 스키장과 미국 Hunter Mt. 스키장에서 한국인, 주한 미국인, 미국인, 재미 한인 들을 대상으로 이용밀도에 관한 선호도를 측정하기 위한 설문조사를 실시한 결과, 1,157부의 설문지를 회수하여, 문화·인종간의 차이를 규명하기 위하여 Kruskal-Wallis test 실시하였다. 연구의 결과로서 재미한국인의 이용밀도에 대한 선호도가 동일 인종인 한국인집단보다 사회 문화적으로 공통성이 있는 미국인집단에 더 유사하였으며 그와 반대로 재한미국인집단은 동일 인종집단인 미국 집단과 차이가 없었다. 이 결과는 혼잡 규범으로서의 이용 밀도의 선호도가 이용자의 개인적 특성 및 인종적 특성뿐만이 아니라 문화인종적 특성에 영향을 받는다는 결론을 얻었다.

Taking the Yosu Peninsula where prestige goods were prevalent and more dolmen were excavated and surveyed than other regions as object of the research, this dissertation investigated the hierarchy of dolmen society. The dolmen groups were excavated and surveyed at some 20 positions in Yosu Peninsula Analyzing the number, weight of upper stone, location, the buried relics of dolmen, the hierarchy for each dolmen group can be summarized as follows. It seems that the large group with a lot of dolmen and big upper stone which is located on the plane with stream or on the lower part of hill might be the central group with abundant buried relics. However, the size of individual upper stone does not coincide with buried relics sometimes. Thus, it is required to review the entirety of dolmen group rather than individual upper stone in the relation between the scale of upper stone and buried relics. Then the scale of tomb is proportionate to the prestige goods. Meanwhile, the discrepancy between dolmens can be verified by the difference among upper stone, tomb, burial accessories, etc in the unit dolmen group. Since dolmen is the tomb of some inhabitants in the Bronze Age, the existence of stone coffin tomb with buried bronze sword, jade or stone sword compared to the stone coffin with no relics means that there was powerful representative of one generation even in one kindred group on the basis of wealth or authority. It can be concluded that the upper stone or large tomb or prestige goods among the persons buried in dolmen were fixed as high class, those with relatively small stone coffin with no or scanty burial accessories were fixed as medium class and multitudinous class who were not buried in dolmen were fixed as low class. Therefore, the dolmen society in Yosu Peninsula shows that there was division of class in the unit dolmen group as well as hierarchy in the group.

Frequencies of each size class, annual change of tuber state and above ground/belowground rate in sect. Pes-gallinaceua group of Corydalis (Fumariaceae) were studied to clarify spring ephemeral´s growth characteristics from 1999 to 2000 in Namhansansung area. Shoot grew from the tuber corresponding with soil thawing in the early growth season, and the deeper tuber was located in soil, the later shoot germinated. Shoot appeared in middle March and died early in May, and the period of total growth season was 45 days. Frequencies were 40% (in total dry weight) or 53% (in tuber´ dry weight) in the smallest size class, and 93% (in total dry weight) or 96% (in tuber´ dry weight) below medium size, therefore, almost all of plants were small. Specific gravity of tuber (SGT) gradually decreased from late growth season to the time that leaf unfolded in next year. At this time, the value of SGT was 0.14. Thereafter, SGT increased to 0.42 at withering time of aboveground part. During growth season, the SGT of flowering plants was lower than that of non-flowering plants. And SGT difference between flowering plants and non-flowering plants was significant at 1% level. In the late growth season, SGT decreased along the increase of tuber volume. The tuber volume roughly increased along the leaf area but there was no a conspicuous trend. Shoot/tuber rate had nothing to do with tuber volume. SGT decreased and leaf area increased along the tuber dry weight, and tendencies of increase or decrease were conspicuous. Therefore, the smaller the plants were, the larger organic matter accumulated in tuber during a growth season. Shoot/tuber rates were various along each plant.

This study is about a blockchain-based collective quarantine management system and its commercialization model. The configuration of this system includes a biometric information transmission unit that generates biometric information based on measured values generated from wearable devices, a biometric information transmission unit that transmits biometric information generated here from a quarantine management platform, and action information transmitted from the community server. is a system including an action information receiving unit for receiving from the quarantine management platform. In addition, a biometric information receiving unit that collects biometric information from the terminal, an encryption unit that encodes biometric information generated through the biometric information receiving unit based on blockchain encryption technology, and a database of symptoms of infectious diseases to store symptom information and an infection diagnosis database. The generated database includes a location information check unit that receives from the terminal of the user identified as a symptomatic person and determines whether the user has arrived in the community based on the location information confirmation unit and the location of the user after the location is confirmed. It includes a community arrival judgment unit that judges. And, the community server helps the interaction between the generated information. Such a blockchain based collective quarantine management system can help to advance the existing quarantine management system and realize a safer and healthier society.
