‘금촌조생’ 품종은 농촌진흥청 원예연구소 나주배연구소에서 1971년 ‘금촌추’의 품질을 개선하기 위해 당도가 높고 육질이 유연한 ‘단배’를 교배하여 1982년 1차 선발되었고, 1997년부터 5년 간 지역적응시험을 거쳐 2001년 최종 선발 및 품종보호출원 되었다. 수세는 비교적 강하고, 수자는 반개장성이다. 꽃가루가 풍부하며, 주요 재배품종과 교배친화성을 보인다. 또한 흑반병에 대하여 강한 포장저항성을 나타내었다. 숙기는 재배중인 ‘원황’ 품종보다 약 5일 정도 늦은 9월 3일로 추석에 출하하기 알맞은 품종이다. 과형은 ‘금촌추’와 같은 도원추형이고, 과피색은 황갈색이다. 과중은 593g이고, 당도는 13.2Bx이다. 육질은 유연하며 과즙이 풍부하고, 석세포가 없어 식미가 매우 우수하다. 그러나 과육선숙형 품종으로 원예적 수확기에도 과피에 녹색이 남지만, 완숙과가 되면 황갈색으로 착색된다. 상온저장 기간은 20일 정도로 다른 조생종에 비해 저장력은 좋은 편이다. ‘Geumchonjosaeng’ pear cultivar (Pyrus pyrifolia var. culta Nakai) originated from the cross between ‘Imamuraaki’ and ‘Danbae’ to improve the fruit quality of ‘Imamuraaki’ cultivar in 1971 at Naju Pear Research Institute of National Horticultural Research Institute (NHRI), Rural Development Administration (RDA). It was preliminarily selected in 1982 and named in 2001. The tree habit shows vigorous growth and upright spreading. It carries abundant pollen grains and shows cross compatibility with leading cultivars. Also it shows high resistance to black leaf spot (Alternaria kikuchiana) in the field condition. Optimum harvest time is around Sep. 3, which is 5 days later than that of ‘Wonwhang’, and it could satisfy consumer’s demand for high quality pear fruit in “Chuseok”. The obovate fruit shape resembles maternal parent, ‘Imamuraaki’ and skin color is green yellowish brown at normal harvesting time and gradually turned to yellowish brown at full ripennig state. Fruit weighs about 593 g, and the soluble solid content is 13.5 ˚Bx. The flesh is very soft and juicy and, rendering good eating quality. Shelf life is about 20 days under the ambient temperature, and it is a relatively long period as compare with other early season cultivars.

A non-symbiotic hemoglobin gene from radish (Raphanus sativus L. var. sarivus) was cloned into the plant binary vector, pBI121, harboring CaMV 35S promoter and a neomycine phosphotranferase Ⅱ (NPT Ⅱ) gene. Cotyledon segments of lettuce "Chung Chi Ma (Lactuca sativa L. cv. Chungchima)" were infected with Agrobacterium tumefaciens LBA4404 containing pBI121 harboring a non-symbiotic hemoglobin gene (RsHb hemoglobin gene). Kanamycin-resistant shoots were obtained on selection medium containing 25㎎/L kanamycin. Induced shoots were rooted in selection medium containing 50㎎/L kanamycin. Regenerated lettuce were cultivated and selfed, and seeds were harvested in the green house. Transformation of the non-symbiotic hemoglobin gene into lettuce was confirmed by polymerase chain reaction (PCR) analysis with genomic DNA. A PCR fragment of 680 bp was obtained from the transformed lettuce. Inheritance of the non-symbiotic hemoglobin gene in lettuce T1 progeny was conducted by PCR analysis. Segregation ratio for the non-symbiotic hemoglobin gene was detected by PCR analysis and observed in 1:1 ratio.

In an effort to improve job satisfaction and organizational commitment in venture business, this study investigates the relation between leadership style and organizational effectiveness of venture business and the influences of the former on followers' satisfaction and commitment. Leadership style was taken as an independent variable, which is classified into 3 types: directive, supportive, and participative. On the other hand, job satisfaction and organizational commitment were regarded as dependent variables. The former means worker's satisfaction on pay, promotion, coworker relation etc., while the latter refers to identifying oneself with an organization and accepting its goals and value, desiring to stay at the organization continuously. Three major hypotheses were set up to be tested and the subjects of the research were 101 workers sampled from five venture business in Busan and Kyungnam areas. Their responses were then analyzed by means of ANOVA and regression methods. The results of the analysis turned out to be as follows: first, participative leadership style shows significant relation with job satisfaction; second, coworker relation is related to organizational commitment; third, participative leadership style leads to cooperative human relation in organization.

연구목적 : 본 연구는 국제적인 정신장애 진단도구인 Composite International Diagnostic Interview(CIDI)를 한국의 사회문화적 상황에 적합하게 번역하고 신뢰도 및 타당도를 평가하여 한국어판으로 개발하기 위한 것이다. 방 법 : CIDI는 정신장애를 평가하고 진단할 수 있는 포괄적이고, 완전히 표준화된 진단도구로 훈련받은 일반인들이 적용할 수 있기 때문에 대규모 역학조사에 적합하다. 세계보건기구에서 제공하는 CIDI 번역 지침에 따라 한국어판 CIDI(K-CIDI)를 제작하였다. 영어권과 한국의 언어 및 사회문화적 차이를 고려하여 번역 및 개정을 하였고 역번역을 통하여 원본의 의미와 일치하는지를 확인하였다. 임상환자를 135명과 일반인 5명을 대상으로 신뢰도와 타당도 검사를 실시하였다. 두 명의 평가자가 K-CIDI를 이용하여 동일한 대상자를 동시에 면담하고 일주일 뒤에 재검사를 실시하였다. K-CIDI로 검사를 받은 대상자들을 정신과 전공의와 임상심리사가 한국어판 Structured Clinical Interview for DSM-Ⅳ를 이용하여 진단을 내렸다. 두 가지 진단의 일치도에 대한 kappa값을 산출하였다. 결 과 : CIDI의 번역에서 한국어 표현이 복잡하고 긴 문항은 두 개의 문장으로 분리하였고, 성과 관련된 표현과 의료체계 및 의료추구행태에서 사회문화적 차이를 반영하였다. 공포장애의 대상과 알코올 및 물질의 종류도 한국의 실정에 맞게 조정하였다. 현장 검사와 역번역 과정에서 K-CIDI가 적절하게 제작된 것으로 평가되었다. K-CIDI의 평가자간 신뢰도 검사는 140명에 대하여 이루어졌고 kappa값은 진단에 따라 0.86∼1.00범위였다. 검사/재검사 신뢰도 검사는 47명에 대해 이루어졌고 kappa값은 진단에 따라 0.42∼0.89였다. K-CIDI의 타당도 검사는 50명에 대해 이루어졌고 kappa값이 진단에 따라 0.50∼1.00의 범위였다. 결 론 : K-CIDI는 한국의 사회 문화적 배경에 적합하게 제작되었고 신뢰도 및 타당도 검사에서 역학연구에 적절한 진단도구로 평가되었다. Objectives : This study aims to develop a Korean version of the Composite International Diagnostic Interview(K-CIDI). Methods : The Composite International Diagnostic Interview(CIDI) is a comprehensive, fully standardized interview that can be used to assess psychiatric disorders and provide diagnoses. The K-CIDI was developed according to the guidelines provided by the WHO. The reliability and validity of the K-CIDI was evaluated by examining 135 psychiatric patients and five community residents. Subjects were jointly interviewed twice with a one-week interval. A psychiatric resident and clinical psychologist jointly determined clinical diagnoses using the Structured Clinical Interview for DSM-Ⅳ. Results : Notable modifications were done on sex-related expression, health system and help seeking behavior, subjects for phobic disorder, and kinds of alcohol and substance. Long and complex questions were divided into two or more questions. Field test and back-translation of the K-CIDI confirmed the appropriateness of the translation of the CIDI. The inter-rater reliability, test/retest reliability, and validity of the K-CIDI indicated kappa values ranging from 0.86-1.00, 0.42-0.89, and 0.50-1.00, respectively. Conclusion : The K-CIDI was deemed to be appropriate for the sociocultural background of Koreans. The reliability and validity of the K-CIDI were judged to be exceptionally acceptable.

In this paper, a new shape feature extraction method of the objects using surface curvatures is described. First, the values of the H & K are calculated from range data as given input. Then objects are assigned in the form of 8 primitives by the signs of the H & K values. But existing methods have the difficulties with the complex object. Therefore, We propose the method for the complex primitives such as cone ridge and cone valley. Finally, the effectiveness of this paper is demonstrated by several experiment.

To assess lead exposure in Korean lead workers, 2047 male lead workers in 17 lead using industries were studied. Study population were divided into 4 occupation categories such as storage battery industry(type 1), secondary smelting and litharge making industries(type 2), PVC stabilizer making industries(type 3) and primary smelting and related industries (type 4). Blood lead and zinc protoporphyrin in whole blood (ZPP) were selected as an index of lead exposure. Hemoglobin and hematocrit were also checked. Fifteen questionnaires of lead related symptoms were provided to all lead workers and filled up by themselves and confirmed by medical doctors. Personal variables such as age, work duration, smoking and drinking habits were also collected. the results were as follows. 1) The mean blood lead, ZPP and hemoglobin of all lead workers were 29.7+12.6㎍/100㎖, 56.5+38.6㎍/100㎖ and 14.6+1.3 gm/100㎖ respectively. 2) While the mean blood lead of lead workers in type 1, 2, 3 and 4 were 28.6+11.6㎍/100㎖, 46.2+15.3 ㎍/100㎖, 46.8+12.1 ㎍/100㎖ and 26.2+10.2 ㎍/100㎖, the mean value of blood ZPP of those workers were 53.6+32.6 ㎍/100㎖, 108.1+87.1 ㎍/100㎖, 98.9 +54.9 ㎍/100㎖ and 45.8+19.5 ㎍/100㎖ respectively. 3) The percents of lead workers whose blood lead were 40-59.9 ㎍/100㎖ and over 60.0 ㎍/100㎖ were 17.6% and 2.1% respectively. Those whose blood lead were 40-59.9 ㎍/100㎖ and over 60.0 ㎍/100㎖ were 15.18% and 0.96% for type 1, 43.59% and 21.79% for type 2, 58.89% and 12.22% for type 3 and 11.82% and 0% for type 4 respectively. 4) The percents of lead workers whose blood ZPP were 100-149 ㎍/100㎖ and over 150 ㎍/100㎖ were 5.17% and 3.17% respectively. Those whose blood ZPP were 100-149 ㎍/100㎖ and over 150 ㎍/100㎖ were 4.66% and 2.04% for type 1, 10.26% and 25.64% for type 2, 23.33 and 13.33% for type 3 and 1.28% and 0.32% for type 4 respectively. 5) The prevalence rate of smoking and drinking of male lead workers in all lead industries were 70.8% and 71.0% respectively. While the mean blood lead of smoker, non-smoker, drinker and non-drinker were 30.24+12.58 ㎍/100㎖, 28.35+12.7 ㎍/100㎖, 30.24 ㎍/100㎖ and 28.74 ㎍/100㎖ respectively, the mean blood ZPP of those were 55.7+37.1 ㎍/100㎖, 58.4+41.9 ㎍/100㎖, 55.7+36.5 ㎍/100㎖ and 58.4+43.3 ㎍/100㎖ respectively. 6) While the correlation of hematocrit corrected blood lead with other lead exposure variables were higher than non-corrected blood lead, the correlation of log-transformed ZPP with other lead exposure variables were higher than non-corrected blood ZPP. 7) The most frequent symptom among 15 lead related symptom questionnaires was 'general fatigue' and the next one was 'feeling irritated with disturbance' and least one was 'acute abdominal pain around the umbilicus' in all lead workers. The overall prevalence of lead workers in storage battery industry and primary lead smelting industry were higher than secondary lead smelting and PVC stabilizer making industries. 8) The prevalence of lead related symptoms was a little higher in 13 symptoms in smokers than non-smokers and in 14 symptoms in drinker than non-drinkers, but they were not statistically significant. 9) Stepwise multiple regression analysis, using overall symptom prevalence as a dependent variable blood lead, blood ZPP, hemoglobin, age, work duration, drinking and smoking habits as independent variables, indicated that smoking habit, drinking habit and age were significantly contributed to the dependent variable. 10) The slopes of simple linear regression of blood lead (independent variable) with blood ZPP and log-transformed ZPP as dependent variable were different among 4 types of lead industries. The slope of lead industries with low mean blood lead were less steeper than those with high mean blood lead.

조규태,서동석,안경준 西原大學校 基礎科學硏究所 1999 基礎科學硏究論叢 Vol.13 No.-

식이 조건(pellet, mixed pellet, egg yolk)을 달리하였을 때, 햄스터의 체중 증가량, 먹이 소비량 및 식이 효율 그리고 각 장기의 차이점을 비교하였다. 햄스터의 체중 증가량과 먹이 소비량의 비교는 ANOVA 검정과 Duncan이 다중비교검정에 기초를 두었고 식이 효율은 상관관계를 통하여 알아보았다. 혼합된 사료를 먹었을 때가 가장 많은 체중 증가량을 보였고 다음은 사료, 난황 순서로 증가하였다. 그리고 햄스터는 난황보다는 사료와 혼합 사료를 더 좋아하였으며, 난황만 먹인 경우 간조직에서 병적인 변화를 볼 수 있었다. The increase of weight, consumption rate of food, and histological structure of golden hamster were compared under different condition of feed(pellet, mixed pellet, and egg yolk). The comparison of increasing rate of weight and consumption rate of food was based on ANOVA test and Duncan's multiple range test. The golden hamsters fed on mixed pellet showed prominent growth but in the case of egg yolk showed poor growth. The golden hamsters preferred mixed pellet and pellet to egg yolk, and showed abnormal histological change on the liver and kidney tissue when only the egg yolk was fed.

This experiment was caried out to investigate the optimum seeding amounts with different seeding methods such as flat drill seeding by tractor, high ridged broadcasting and flat broadcasting by power tiller in direct seeded rice on experimental fields of Chungbuk Provincial Rural Development Administration in 1990. The results were summarized as follows ; Labor requirements from seeding to transplanting were decreased about 85% in flat drill seeding by tractor, about 79% in high ridged broadcasting, and about 77% in flat broadcasting by power tiller compared with that of machine transplanting. Seeding stand per m2 and percentage of seeding emergence were the highest in flat drill seeding by tractor compared with those of others. Optimum seeding amounts were 5kg/10a in flat drill seeding by tractor, whereas it was 7kg/10a in other treatments. As the seeding amounts were increased, no. of panicles and grains per m2 were increased, and it showed the highest in flat drill seeding by tractor. Ripened grain ratios hod low tendency as the seeding amounts were increased. In yields, it was the highest in flat drill seeding by tractor compared with seeding methods. Comparing yields with different seeding amounts, it was higher in seeding of 5kg/10a with flat drill seeding by tractor, while it was higher in 7kg/10a with other treatments.

This study was conducted in 1986 to investigate the vivaparous germination in rice. Two varieties, Daeseongbyeo and Chilseongbyeo, were transplanted on May 25 and June 5 and panicles were harvested 5 times with the interval of 5 days beginning 30 days after heading. Panicles were seeded in incubator at 20℃ right after harvest and after drying and storage to observe the germination. Rate of viviparous germination of Daeseongbyeo was higher than that of Chilseongbyeo regardless of the seeding time. Rate of vivaparous germination of May 25 transplanting was higher than that of June 5 transplanting. Germination of Daeseongbyeo was not afftected by seeding time. Viviparous germination rate of Daeseongbyeo appeared to be increased as the harvesting was posponded. On the other hand, Chilseongbyeo did'nt germinate when seeded right after harvesting and rate of vivaparous germination was decreased as the harvesting was postponded. Vivaparous germination was higher in the order of top > middle > bottom part on a panicle, while grains on the primary branches showed higher vivaparous germination than those on the secondary branches.
