Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

우리나라 4년제 대학졸업자의 직업교육훈련 성과분석 : 교육투자수익률 추정을 중심으로 With The Estimation for The Rate of Return to investment in Education

장창원,이지연 한국직업능력개발원 1999 직업능력개발연구 Vol.2 No.1

ABSTRACTThe purpose of this study was to provide the practical policy suggestions for the re-vitalization of vocational education and training at the higher level of education. For the purpose, data from ^P Earning Structure Basic Statistics Survey Reportj was re-analyzed with such variables as educational level, gender, individual who have or not a qualification, and the kinds of qualification. Jacob Mincer earnings function was used to explain and predict the differences between groups on the suggested variables by estimating the rate of return to investment in education.The empirical estimation of the rate of return to investment in education was concluded that adults with higher levels of education (Bachelor's degree : 15.8%) were more likely to have a high wages in the labor market than those with less education (High school graduate : 8.6%, Associate degree:11.7%). For the rate of return to investment by education level for those who have a qualification, 13.8 percent was shown to adults with a bachelor's degree, compared with 10.3 percent of persons with associate degree, and 7.4 percent of persons with high school graduate. In contrast, for those who have a non-qualification, 14.9 percent was shown to adults with a bachelor's degree compared with 10.7 percent of persons with associate degree, and 7.4 percent of persons with high school graduate.The rate of return to investment in education for adults who have a non-qualification with bachelor's degrees were 1.1 percent higher than the persons who have a qualification with similar levels of education. This results show the evidence that persons with lower levels of educational attainment were more likely to have a lower wages in the labor market than those who had a higher levels of educational attainment. Futhermore, persons who have a non-qualification with higher levels of educational attainment were more likely to have a higher wages in the labor market compared with persons who have a qualification with higher levels of educational attainment. This result revealed that acquirement of qualification is not important issue to judge the performance of the vocational education and training nor standard for employability for entering labor market. Statistics on educational attainment of the entire population show that graduation from university is not simply an academic honour. Educational attainment reflects admission to a particular position in society and influences even job opportunities. His or her own employability by acquirement of qualification does not value in our society. Most business and industry differentiate between those jobs which require a university degree, regardless of qualifications or skills, and those that do not. Regardless of his or her ability, social status as determined by university graduation, has become more important than employability.For making a change from the degree-oriented toward person's ability-oriented valued society, vocational education and training at the higher level of education must emphasis in a new direction. Followings are the summary policy suggestions for the re-vitalizing vocational education and training at the university, where is the place for development of workforce and for preparing world of work.1) Most Korean youth want to go to four-year university after high school. The percentage of high school graduates who indicated plans to enter a four-year university increased to "get a better job" and "make more money". However, a large percentage of graduates from four year universities have a significant problem finding employment. Higher level of education must play a important role to make students as a employable person during their 4 year of campus life. Thus, vocational education and training must emphasis at the university level with changing curriculum structure.2) Curriculum at the higher level of education of the 21century may focus more on helping students transferable workplace competencies and advanced work-related technology in a variety method rather than a simple theoritical knowledge delivery in one way communication teaching structure.3) Changes in qualification system may emphasis more on workplace readiness and assessment process with collaborative partnership with business/industry and university.4) Much attention must directed to the role and responsibility of 4-year university in creating and disseminating the practical and advanced knowledge and technology for those who can meaningful transfer university to work beyond Bachelor's degree only.

A change in economic and social environment has brought lots of changes in lifestyles and values of onsumers. This paper presents fashion conformity, innovativeness and clothing values of college students according to their academic majors. Respondents were 181 undergraduate students with diverse majors. The survey was conducted using a questionnaire designed to measure fashion conformity, innvativeness and utilitarian/hedonic clothing values. Seventeen items measuring fashion conformity and innovativeness and thirty six items measuring clothing values were adopted from existing studies. Chi-square, ANOVA, and multiple comparisons of means were conducted. Students were clustered into three groups of majors: Engineering/NaturalScience/Information majors (ENI), Business/Social/Humanity (BSH) majors and HumanEcology/Art/PhysicalEducation (HAP) majors. HAP majors were more innovative than ENI majors. Significant differences were found in hedonic and utilitarian aspects of clothing values. HAP majors had higher level of novelty/fun/attraction, fashion consciousness and social appraisal sensitivity dimensions. ENI majors showed higher level of comfort seeking among clothing values. No significance was found in clothing confidence, mix and match, economy, utility and handling dimensions of clothing values across different groups of majors. Results of this study imply that the consumer group according to a major has relation to fashion conformity, innovativeness and clothing values.

The precise leveling is one of the important means of investigating fluctuation of earth's crust and foreknowing earthquake. This paper aims to study refraction errors developed in the inclined leveling route. Based on Kukkamaki's theory and data of weather, the author devised on experiment to test how Kukkamaki's corrections improved the discrepancy between fore and back sight leveling in actual slope. Especially, in inclined leveling, the distance of line of sight in ideally to be 25~30 meters to minimize refractions errors. From the results of experimental test of continuous inclined leveling route, the values of calculation by Kukkamaki's corrections were found to be nearly in accord with the values of observation.

왕지원,민해기,장영효,강국희 성균관대학교 생명과학자원연구소 1995 生命資源科學硏究 Vol.2 No.1

Random Amplified Polymorphic DNAs (RAPD) has been applied to the identification of human intestinal anaerobic Bifidobacteria. Recently, The RAPD technique has been used to analyse DNA polymorphism of genomic DNA from eukaryotes such as plants and animals(1, 3, 4, 10, 11). But there were only several reports on the polymorphism of prokaryotic genomic DNA by using this method(2,7). Total 100 random sequence primers were used in screening of species-specific primer. The oligonucleotide primers were ten bases long and designed to have average G+C contents of 60 mol %. Eight species of Bifidobacteria from human feces were selected. According to conventional method genornic DNA were extracted from each bifidobacterium and then RAPD-PCR was performed. Four primers have produced distinct electrophoretic band patterns, RAPD markers. Especially arbitrary primer # 101 showed species-specific DNA polymorphism for each of Bifidobacterial genomic DNA tested. The arbitrary primer # 101 showed good reproducibility when the PCR conditions were optimized. And also primer # 156, # 174, # 183, have produced amplified PCR products but not for all of the strains tested. Better DNA polymorphism was observed when two arbitrary primers were used in combination.

본 연구는 돼지의 체외수정에 있어서 난포란의 회수방법과 체외수정란 및 체외발달율을 조사하여 체외수정의 기본 원리를 밝히고자 본 연구를 수행하였다. 도축장으로부터 채집한 난소의 난포에서 흡입법, 세절법 및 흡입후세절법 등으로 난포란을 채취하여 등급별로 분류하여 회수율을 조사하였으며, 채취한 난포란은 액상정액과 정소상체미부 정액을 사용하여 체외수정을 시킨후 TCM-199 와 NCSU-23 배양액으로 체외배양을 실시하였다. 본 연구에서 얻은 결과를 요약하면 다음과 같다. 회수방법당 각각 37개의 난소에서 회수한 난포란의 수는 흡입법이 1,365개, 세절법이 1,884개 및 흡입후 세절법이 3.830개로써 난소당 난포란의 수는 각각 36.9, 50.9 및 103.5개로써 회수방법간에 유의적(P<0.05)인 차이가 있었다. 액상정액과 정소상체미부 정액을 사용하였을 때 수정율은 각각 83.0 및 83.% 로써 정액간에 유의적(P<0.05) 인 차이는 없었다. 체외수정이 이루어진 난자들의 분할율도 액상정액(60.8%) 과 정소상체미부 정액(69.0%) 간에 유의적(P<0.05) 인 차이는 없었다. 2-4세포기로의 발달율은 24.6 및 28.4%로써 배양액간에 위의적(P<0.05)인 차이는 없었으며, 상실배로의 발달율도 TCM-199 와 NCSU-23 배양액이 각각 14.8 및 24.5% 로써 이들간에 유의적(P<0.05)인 차이는 없었다. To improve the efficiency of in vitro production of embryos with follicular oocytes in pig, the recovery rates, in vitro fertilization and development, and the time required for collectng and processing oocytes by aspiration with or without slicing were evaluated comparatively. The oocytes were collected by aspiration of follicles(2-6mm) with or without slicing ovaries after aspiration, and classified into grade I-IV oocytes by the morpholoy of cumulus cells attached and the homogeneity of cytoplasmic granules. The grade Ⅰ-Ⅱ oocytes were matured invitro for 46 hours in TCM-199 and NCSU-23 supplemented with 1㎍/㎖ FSH, 2IU/㎖ hCG, 1㎍/㎖ estradiol-17 at 39℃ under 5% CO_2 in air. They were fertilized in vitro by epididymis sperm and ejaculated sperm treated with hypotaurin for 24 hours. and then the zygotes were co-cultured in vitro with pFF(porcine follicular fluid) for 7-9 days. The results obtained were as follows: The number of ocytes recovered per ovary was averaged 30.7 by aspiration, 50.8 by slicing and 103.5 by aspiration post slicing. The number of grade Ⅰ oocytes recovered was total 0.2% by aspiration, 0.1% by slicing and 0.1% by aspiration post slicing. The oocytes recovered per ovary was significantly(P<0.05) higher as recovery methods. The cleavage rates of the embryos obtained from 83.0(ejaculate sperm) and 83.1(epididymis sperm) respectively(P<0.05). In vitro developmental rates(9.9 and 18.6%) of embryos cultured in TCM-199 and NCSU-23 up to morula stage were non significantly(P<0.05) different between the culture media.
