씨감자를 사용할 때 발생하는 수량감소는 씨감자의 퇴화에 그 원인이 있는데 이는 PLRV, PVY와 같은 virus 감염에 의한 병리적 원인, 비정상적인 물질대사에 의해 강엽 내 성분량의 변화가 씨감자의 생산력을 저하시키는 생리적 원인 및 기상조건과 같은 환경요인이 주로 관여한다. 이에 따라 생장점 배양에 의해 무병주를 획득하고 이를 기내에서 대량으로 증식시킨 후 격리 온실에서 씨감자를 생산하는 방법이 널리 이용되고 있고 기내 괴경형성에 대한 실험도 많이 이루어지고 있다. 기내에서의 shoot 증식에는 여러 가지 생장조절물질, 특히 kinetin, BAP, zeatin등이 효과적으로 이용되며 shoot로 부터의 기내 소괴경의 유도는 배지 내 당 농도의 증가, ancimidol과 같은 생장억제제, 암 배양이나 단일조건의 부여에 의해 쉽게 이루어진다. 기내 줄기의 삽목 증식 후 이를 노지에 이식하여 소괴경을 형성시키는 방법의 경우, 현재까지는 주로 배지조건에 치중하여 왔으며 광 조건, 온도, 배양용기의 환기 등에 관한 연구는 많이 되어 있지 않은 상태이다. 따라서 노지에서의 순화율 및 이후의 생장 저하 등 많은 문제점이 발생하고 있다. 또한 한정된 크기의 배양용기를 이용함에 따라 신초의 길이 생장이 억제되고 이에 따라 마디의 수도 감소하여 증식 효율이 낮아지게 된다. 따라서 포장에서의 원활한 순화와 식물체 생율을 위해서는 배양환경, 즉 광도, 광 주기, 배양용기의 환기방안, 기내 광합성 유도 등에 대한 연구와 함께 새로운 배양용기의 개발이 필요하다. 한편, 기내 괴경을 이용한 씨감자 생산은 시간, 노동력 및 생산비용이 많이 소요되는 것에 비해 생산 효율은 높지 않은 등 여러 문제점들이 지적되고 있다 .최근 많이 연구되고 있는 양액 재배에 의한 무병 종서 생산은 기내 소 괴경 이용 방식에 비해 괴경 크기가 크고 식물체 당 괴경 수가 월등히 많아 직접 씨감자로 이용할 수 있는 장점을 가지고 있다. 본 실험에서는 생물 반응기에서의 배양 방식이 감자 shoot의 기내 생장에 미치는 영향과 양액 재배 시스템에 따른 식물체 생육 및 괴경 형성 정도를 비교하였다.

The purpose of this study is to find out how middle and high school girls show their clothing attitudes and their life-style, clothing behavior, use their ornaments according to demographic variables. The subject of this study consists of 345 middle and high school girls living in Chung-Nam Province and Taejon Metropolitan City. SPSS/PC+program was utilized to calculate frequency(N), mean value(M) and standard deviation(SD) for statistical analysis. Differences among the populations are examined through t-test, F-test and X2-test. The results of this study are as follow: 1. Correlation between the life style and demographic variables. Especially, life-style has significant difference(p<. 05) according to type of school, middle school girls have high tendency in the type of modern and fashion. Life-style has significant difference(p< .01) according to level of achievement studying, high level girls has high tendency in the type of practical and secure. 2. Correlation between the clothing behavior and demographic variables. According to type of school, middle school girls showed higher than high school girls in clothing conformity and clothing aesthetics. According to level of achievement studying, high level girls have high tendency in clothing conformity and clothing modesty. 3. Correlation between the use their ornaments and demographic variables. Buying the ornaments, higher-level achievement studying girl's get information in show window, but lower-level achievement studying girl's get information in TV or raido. The use of ornaments according to the site of school, most of school girls who live in small city or town use the ornaments as usual school life, but school girls who liven in big city use the ornaments to look good on their clothes. Following suggestions can be made based on the discussions above: It is necessary for us to have correct understanding about the correlation between the ornaments and clothing of school girls in order to lead them to have appropriate clothing behavior. Furtheromore, it is required to construct a bridge linking a course of study to rational habits guidance which will provide us more appropriate tools for clothing behavior guidance.

The purpose of this study is to systematize the objectives and contents related to clothing education curriculum, and to research the needs for clothing education curriculum required by the Home Economics teachers working form elementary school to high school. These needs have been shown in the research by questionaires, which were distributed to the teachers in the Department of Home Economics School in Taejon and Ch'ungch'ongnam-do. The main results of obtained this study are as follows: First, as the objectives of clothing education curriculum, which are different from each school and each grade, have not completely been systematizied, they must be carefully reexamined and reorganizied in a coherent system. Second, in the findings on the teacher's needs of clothing education curriculum, the Home Economics teachers in elementary schools have basic knowledges and skills on clothing education. The teachers in middle schools have the knowledge of the selection, care repair of cloths and also acquire skills for clothing education and consumption activities. The teachers in high schools have the knowledge of clothing-related to industry and know the way of searching for their curse. The objectives of clothig curriculum have been systematizied among schools. Third, as the levels for elementary schools of the contents of clothing education curriculum are some what difficult for elementary students to understand, and the contents have been overlapped with those of middle schools curriculum, they are not organized in a coherent system of clothing education curriculum higher than over, and to systematize clothing education in a coherent and a unified way, we must continue to study them and the needs for clothing education.

한영란,김수근,하은희 大韓産業醫學會 2002 대한직업환경의학회지 Vol.14 No.4

목적: 소규모사업장 보건기술지원사업에 참가한 보건관리자들을 대상으로 그동안 수행한 보건기술지원사업의 경험에 대해 focus group interview를 이용한 개방적 논의를 실시하여 본 사업의 내용과 효과, 진행과정에서의 어려움 그리고 평가 및 대안을 체계적으로 분석, 제시하여 보다 충실한 개선 전략을 모색할 수 있는 기초자료를 제시하고자 시도되었다. 방법: 포커스 그룹방법론을 이용하였다. 즉 포커스그룹인터뷰를 통해 자료를 수집하고 Strauss와 Corbin(1990)이 제시한 근거 이론 방법으로 자료를 분석하였다. 연구대상자는 총 20명으로 의사 6명, 간호사 14명이었다. 결과: 최종 분석 결과 총 69개의 개념이 도출되었으며 이 개념들로부터 28개의 하위범주와 5개의 상위범주가 도출되었다(Table 2). 상위범주는 사업목표, 다양한 사업, 사업진행 시 어려움, 사업평가 및 대안모색 등 5개이다. 첫째 상위범주인 사업목표에는 사업목표 1과 2가 하위범주로 포함되었고 둘째 상위범주인 다양한 사업내용이 하위범주에는 집단보건교육, 건강상담 및 개별교육, 건강증진사업, 건강검진, 유소견자 관리, 작업환경관리, 응급처치 및 구급함과 성공전략이 하위범주로 포함되었다. 셋째 상위범주인 사업진행시의 어려움에는 보건관리의 중요성에 대한 인식부족, 보건관리에 대한 사업주의 비협조적 태도, 본 사업에 대한 사업주의 부정적 인식, 짧은 사업기간과 방문횟수 부족, 유소견자에 대한 부당한 처리, 비효과적인 사업의 지침, 모니터 요원의 능력 및 연계성 부족, 보건관리자의 자존감 저하, 기타 어려움이 하위범주로 나타났다. 넷째 상위범주인 사업평가에는 사업에 대한 총평, 건강관리 및 작업환경관리 사업장의 구분, 팀 방문, 기관평가인 하위범주가 포함되었다. 다섯째의 상위범주인 대안모색에는 효과적인 사업을 위한 전제, 현 사업의 활성화 방안, 사업장 특성에 맞는 자율적인 사업구축, 기본모형구축, 기타 대안이 포함된다. 결론: 본 연구결과 보건기술지원사업을 받은 소규모사업장은 사업장 보건관리의 중요성을 다소 인식하여 보건관리를 시행할 가능성은 높아졌으나 자율적 보건관리능력개발을 위한 변화는 아직 요원한 것으로 나타났다. 본 사업이 성공하기 위해서는 대상자의 특성과 요구를 반영하는 현실적 사업을 제공하고 기준 이상의 방문과 서비스 제공, 업무의 지속성 유지를 위해 대상자와의 신뢰감을 형성하는 것이 중요한 것으로 나타났다. 또한 서비스기관이 질적 향상과 보건관리자의 전문성향상 그리고 권한강화가 선행되어야 하고 노동부/공단, 서비스 기관과 사업장의 삼자구조가 보다 적극적인 의미에서 협조적 관계가 되어야 하는 것으로 나타났다. 마지막으로 사업장 특성에 맞는 자율적 사업구축을 위한 프로그램 다양화, 시범사업 사업장 특성별 모형구축과 보건관리자 역할모델등이 대안으로 나타났다. Objective: This study was conducted to provide the fundamental information to prepare better strategies based on the experiences of occupational health care providers who are involved in the Government-funded subsidized occupational health programs for small scale industries. Methods: The focus group methodology was used in this study. The data was collected using focus group interviews and analuzed in the framework of the Grounded theory method as mapped by Strauss and Corbin(1990). The subjects enrolled in this study included 20 occupational health care providers in the Government- funded subsidized occupational health program for the SSI: 6 doctors and 14 nurses. Results: We indentified 69 concepts, 28 sub-categories and 5 categories(Table 2). The categories were the Program's Goals, Various Services, Difficulties in Implement Services, Program Evaluation, and Suggestions for Alternative Plans. Conclustions: This program showed that autonomous health management ability has not changed altouugh the possibility for small scale industries to start the health management arose by acknowledging the importance of the health management in the workplace. A successful program should provided a practical service that is planned by the characteristics and the requirements of the workers, a better service than the standaed, more visiting times, and a trusting relationshop among workers. The occupational health agency's quality and the health manager's specialty needs to e improved and the health magager's authority should be consolidated. And actively cooperative triangular relation among the Labor Department/KOSHA, service organizations, and the workplace is required. In addition, alternative plans were suggested. These included various programs for planning an autonomous service suitable for the quality of the workplaces, a model set-up suitale for the quality of the workplaces, and a role model set-up for the health manager.

김명란,김윤희,조은희 조선대학교 사범대학 부설 교과교육연구소 2000 敎科敎育硏究 Vol.3 No.1

Recent advances in biotechnology has centered around the field of genetics. Although the likely benefits of biotechnology is obvious, it is assuring that the potential risks has to be carefully weighed. It also rasied new social and ethical issues in everyday life experiences. Thus, biology education especially in the units on biotechnology and genetics should emphasize social implications of the technology. In this study, the "Continuity of Life" unit in high school biology Ⅱ curriculum was analyzed in the context of Science, Technology and society(STS). The unit, "Continuity of Life", describes basic genetic phenomena and evolution of life. five different high school biologyⅡ textbooks were chosen and inquirty content dimension, and the inquiry process dimension. Analyses of the inquiry content dimension showed that 40.6% of inquiry activities in the unit were devoted to the evolution part and those for cell division, reproduction and development, and Mendelian genetics were at most 8.7%, 13.0%, and 16.0%, respectively. In the inquiry process dimension. ´interpreting data and formulating generalization´ and ´observation and measuring´categories consist of 81.1%. The other categories, ´seeing a problem and seeking ways to solve it´and ´building, testing, and revising the theoretical model´were under represented. In the context dimension, the scientific context consists of 73.0% and the proportion of the other three categories, individual context, the social context, and the technical context was only 26.1% in total. In conclusion, the analysis of inquiry activities on the "Continuity of Life" unit in five textbooks composed based upon the Sixth Curriculum of High School Education failed to show intimate relationship between science and society and simply concentrated on description and explanation of scientific facts. Provided the fact that the Biology Ⅱ is used in the highchool class for students who want to be future natural science majors of who show special interests in natural science, it is important for students to understand the ethical and social issues that recent biotechnology rasied and to become scientifically literate and responsible persons.

열처리에 따른 Poly(Ethylene Terephthalate-co-Sebacate)의 가수분해에 관한 연구

백애란,최은경 효성여자대학교 가정대학 학도호국단 1984 家政大論集 Vol.3 No.-

In order to modificate polyester fiber, the polyethylene terephthalate(PET) was copolymerized with sebacic acid(SA). In this experiment the substitution rate of comonomer(SA) was controlled from 5 mil% to 30mil%, and all samples were used in film. When the hot-pressed films were hydrolyzed at 80℃ by using 10% NaOH, the weight loss increased with increasing SA mol% of copolyester. On the other hand, when the films were heat-treated the weight loss of PET and the copolyester containing 5 or 10 mol% of SA were increased. But the weight loss of the copolyester containing 20 or 30 mol% of SA were lowered.
