목적 : 본 연구는 수근관 증후군의 발생위험이 높은 작업형태에 종사하는 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장과 목재소 근로자에서 근전도검사를 이용하여 수근관 증후군의 유병률을 조사하고자 하였다. 방법 : 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장 근로자 69명과 목재소 근로자 17명을 실험군으로, 관리직, 경리, 경비등 상지의 단순반복작업이 없는 근로자 28명을 대조군으로 선정하여, 작업적 및 병력조사, 이학적 검사와 근전도검사를 통해 수근관 증후군의 유병률을 조사하였다. 결과 : 수근관 증후군의 유병률은 육류 및 어류 가공 사업장과 목재소에서 각각 26.09 % (18명)와 29.41 %(5명)로 조사되었으며, 육류 및 어류가공사업장과 목재소 근로자를 '7년 이상과 미만의 작업기간'으로 층화하여 비교한 결과 '상지부위의 통증 호소 유무', 'Visual Analogue Scale(VAS: 총 10점) 4점 이상 여부', 'Tinel teat 양성 유무', 'Phalen test 양성 유무'는 모두 단기 작업근로자군에서 양성의 빈도가 증가되었고 '수근관 증후군 유무'는 장기작업근로자군에서 양성의 빈도가 증가되었다. 결론 : 육류 및 어류 가공 사업장과 목재소의 수근관 증후군 유병률은 각각 26.09 %와 29.41 %로 육류 및 어류 가공 사업장과 목재소는 1996년 OSHA가 지정한 바와 같이 위험한 작업요인이 있는 작업장으로 분류하여 관리되어야 할 것으로 생각된다. Objectives : This study was carried out to survey on the prevalence of Carpal Tunnel Syndrome(CTS) in high risk jobs(meat and fish processing plant and wood plant), by application of Nerve Conduction Study(NCS), a confirmatory diagnostic method. Methods : Experimental group was 69 workers sampled from meat and fish processing plants and 17 workers sampled from wood plants, who were simple, repetitive workers using upper extremities and control group was 28 workers sampled from managers, secretaries and keepers. All employees were examined through work history, physical examination and NCS. Results : 18 workers(26.09%) in meat and fish processing plants, and 5 workers(29.41%) in wood plants had compatible findings to NIOSH diagnostic criteria for CTS. The experimental group had more symptoms (complaint of upper extremities, Visual Analogue Scale ≥4(VAS: total 10 point)), signs(Tinel and Phalen test) and prevalence of CTS than control group(p<0.05). The prevalence of symptoms and signs were higher in short term workers(<7 years), but the prevalence of CTS was higher in long term workers(≥7 years). Conclusions : The prevalence of CTS in meat and fish processing plant and wood plant were 26.09% and 29.41% respectively. Authors propose that meat and fish processing and wood plants should be managed as a risk job category which were designated by OSHA in 1996

In order to investigate the useful gene(s) of wild rice species, the bacterial leaf blight test with 101 lines of the genus Oryza were examined. The eighteen lines of wild rice species showed equally resistance reaction from group III, IV and V that is, bacterial leaf blight, Xanthomonas oryzae (UYEDA et ISHIYAMA) DOWSON. The resistant lines of wild rice were W0065, W0066, W1134, W1149, W1199, W1201, W1252, W1268, W1302, W1539, T2018, O.m, W0015, W1408, Y20, W1519, W1525, and W1527.

The callus induction ratio and the callus growth ratio of buckwheat and tobacco were investigated using the different kinds of media and hormones and the different concentrations of PFP and hormones to determine the optimum conditions of callus culture. The highest ratios of callus induction in buckwheat and tobacco were respectively observed in the medium containing 1mg/1 2,4-D in the dark (68.4%) and in the B₅ medium containing 2mg/1 2,4-D in the light (82.5%). In tobacco, callus induction ratio was decreased as PFP concentrations increased in the mixture of 2,4-D and PFP as well as in the addition of PFP alone. None of callus was formed over 10mg/1 PFP in the mixture of 2,4-D and PFP while callus induction of 5% was observed even in 80mg/1 PFP in the addition of PFP alone. Dicamba in the media MS and NN affected better callus growth of buckwheat than 2,4-D and picloram did. Fresh whight of tobacco callus increased markedly in the MS medium compared to the media B₅ and NN. Fresh weight of buckwheat callus was more increased in the mixture of 2,4-D and PFP rather than in the addition of PFP alone while that of tobacco callus was higher in the addition of PFP alone.
