  • Potato virus Y (PVY) is an important viral disease in burley tobacco in Korea and is mostly transmitted by green peach aphid, Myzus penicae, in nature. Effects of barrier nets on the immigration of the aphid population into tobacco fields and on the control of PVY were investigated in 3 tobacco fields with 1.8 m - height polyethylene (PE) nets on their outer - sides in Iseo - Myeon, Wanju - Kun, Cheonbuk. Immigration of aphids to the tobacco yields started at late April and reached maximum at early June. The immigrating aphid population was apparently blocked by the barrier nets to be reduced by 54-73%. PVY severity was also reduced by the barrier nets. However, the control value was variable, ranging 24-67%, which suggests that effect of the PE net barrier on the prevention of aphid-borne virus might be variable depending on the location and slope of the fields.

  • 국민건강보험공단이 담배회사를 상대로 손해배상 청구소송을 진행 중에 있다. 담배회사는 전통적으로 소송 진행 과정에서 과학적 근거를 오용하거나 과학자를 포섭하여 소송을 유리한 방향으로 이끌어 가기 위한 노력을 해왔다. 본 연구는 전 세계적으로 주목 받고 있는 국민건강보험공단의 소송 과정 중 담배회사의 전략을 분석하였다. 선행연구를 통해 이미 밝혀진 담배회사의 담배소송 전략을 이해한다. 국민건강보험공단 소송 중 법원에 제출된 소장, 준비서면, 증거자료 등에 대한 내용분석을 통해 담배회사의 소송 전략을 파악한다. 국민건강보험공단의 소장 내용 중 첨가물 사용과 관련된 쟁점에 대해 담배회사는 세계보건기구의 "Tobacco: deadly in any form or disguise(2006)" 보고서 중 'American spirit'과 같은 천연담배로 광고하는 담배제품에 대한 의견을 마치 첨가물이 들어간 제품과 천연담뱃잎을 사용하는 담배제품 간 위험성이나 중독성에 차이가 없다는 내용으로 준비서면을 작성하였다. 하지만 원래 보고서 내용은 첨가제가 들어가지 않았다고 광고하는 천연담배의 위험성을 경고하는 내용이었다. 즉, 보고서의 작성 의도를 무시하고 정반대의 해석으로 과학적 근거를 오용하였다. 또한 준비서면 내 다른 해외자료들은 영문 그 자체로 참고문헌에 수록하였지만 세계보건기구 보고서는 한글로 번역하였고, 그 이유는 아마도 보고서 제목의 "deadly"가 부담스러웠던 것으로 해석된다. 또한 국민건강보험공단 소송 이전에 제기되었던 개인소송 중 담배회사가 법원에 제출한 증거자료의 일부를 분석한 결과 담배회사의 컨설턴트로 활동한 과학자의 연구결과를 증거자료로 제출한 것도 확인할 수 있었다. 국내 담배소송에서도 해외사례와 마찬가지로 담배회사의 소송전략은 유사했다. 담배소송 결과는 담배규제정책에 막대한 영향을 미친다. 성공적인 소송을 위해 보건의료분야 전문가들은 담배회사가 제출하는 방대한 분량의 의견서와 증거자료에 대한 적극적인 관심을 가져야 한다. 또한 담배회사의 과학자 포섭활동을 인지하고 세계보건기구 담배규제기본협약(Framework Convention on Tobacco Control) 제5조3항의 권고사항처럼 담배업계와의 협력을 거절해야 할 것이다.

  • Endonuclease inhibitor was isolated from the chloroplast of the leaves of tobacco, Burley 21 and NC 83, The inhibitory effect on the activities of endonucleases including BamH1 was lost by the addition of trypsin or heat treatment However, the treatment of $\alpha$-amylase was unconcerned in the inhibitory effect The endonuclease inhibitor was found to be a monomeric protein that plays a vital role for protection of tobacco chloroplast DNA from endonuclease action.

  • Tobacco mosaic virus (TMV) was detected from Kimchi by biological and serological assay 5. Kimchi samples three month after cooked were collected, and were inoculated on N. tabacum var. Burley 21 and NC 95. Out of 33 samples, 6 showed typical symptoms induced by TMV, local necrotic lesions on Burley 21 and mosaic on NC 95. All saps from tobacco leaves showed the mosaic symptom reacted positively against TMV antiserum by agar gel double diffusion test. Based on the results, the Kimchi is considered as one of the important inoculum sources in Korea.

  • Some or the parameters affecting the thermal analysis of different types of ground tobacco have been discussed. The sample, Korean flue- cured and burley and Greek orient tobacco leaves were run in air at heating rate of $10^{\circ}$ and 20^{\circ}C$ per minute. The thermograms obtained were divided into four temperature zones. The effect of different heating rates on thermal degradation has been discussed At the lower heating rate the maxima of DTA curves in zone 3 and 4 were 25-$40^{\circ}C$ lower than that of the higher heating rate.

  • The hollow stalk, caused by Erwinia carotovors var. carotovora, is probaly the most devastating disease to burley tobacco in Korea. There are two modes of infection to tobacco plants: the primary infection along the plant stem from soil and the secondary one from the topped end of plants. The secondary infection rate could be reduced to almost zero by applying an antibiotic, streptomycin sulfate(400 ppm solution), right after topping.

  • Three kinds of inoculation methods, capillary, root cutting and dipping were compared for an efficient way to screening the resistant tobacco variety against bacterial wilt, Ralstonia solanacearum. The pricking a capillary tube contained the pathogenic bacterial suspension(10$^{7}$ cfu/$m\ell$) to an axillary bud of each tobacco plant showed different resistance well between varieties. The less period was required in inoculating work and in disease development for the inoculation method used with capillary tube than for two other inoculation methods tested also.

  • Field experiment was conducted to investigate the effect of vinyl mulch on phosphate availability of soil and fertilizer in 1982. Growth of tobacco was more vigorous at each level of phosphate treatment in vinyl mulched than in bare soil. There was significant culture x Phosphorus treatment interaction for the yields of cured tobacco leaves. These results indicated that vinyl mulch was effective to improve phosphate availability of soil and fertilizer. Increase in soil temperature and maintenance of bulk density suitable for Phosphorus diffusion by vinyl mulch were likely to Play major roles on Phosphate availability, but other unknown factors appeared to be involved.
