이 연구는 무인도서의 생태보존권역 설정을 위하여 지형경관을 평가하고 등급화 하였다. 이를 위해 신안지역에 신안군 지역에 산재한 20개를 현지조사 하였다. 연구결과, 신안군의 무인도서는 절대보전지역(I), 보존지역(II), 준보존지역(III), 이용가능지역(IV)으로 분류할 수 있었다. 그 결과, 절대보전지역(I)으로 평가된 도서는 흑도, 장도, 소룡도, 죽도, 지실도, 하죽도 등 6개이며, 보존지역(II)으로 평가된 도서는 저도, 장구섬, 마도, 인도, 기상도, 송도, 상죽도, 대과도 등 8개이며, 준보존지역(III)으로 평가된 도서는 소장도, 소송도, 안도 등 3개 이며, 이용가능지역(IV)으로 평가된 도서는 소기도, 가학도, 소죽도 등 3개이다. 특히 절대보존지역 및 보존지역으로 선정된 도서는 지형경관 자원이 우수해 훌륭한 자연학습장 또는 야외연구실로 활용될 수 있을 것으로 기대된다. This study has evaluated and leveled the geomorphological landscape for the setting of an ecological preservation zone on uninhabited islands. The 20 uninhabited islands, which are scattered around the Sinan-gun region have been surveyed on field. As a result of study, uninhabited island off Shinan-gun was classified the absolute preservation areas(I), preservation areas(II), quasi-preservation areas(III), and a available areas(IV). These results evaluated 6 islands of Heuk-do, Jang-do, Soryong-do, Juk-do, Jisil-do, and Hajuk-do to be absolute preservation areas(I), the 8 islands of Jeo-do, Janggu Island, Ma-do, In-do, Gisang-do, Song-do, Sangjuk-do, and Daegwa-do to be preservation areas(II), the 3 islands of Sojang-do, Sosong-do, and An-do to be quasipreservation areas(III), and the 3 islands of Sogi-do, Gahak-do, and Sojuk-do to be available areas(IV). Those islands selected as absolute preservation areas and preservation areas have especially outstanding geomorphological landscape resources, and are expected to be able for use as natural study fields or as outdoor laboratories.

Background: Ginseng (Panax ginseng Meyer) is an important medicinal herbs in Asia. However, ginsengvarieties are less developed. Method: To developed ginseng varieties, a pure line selection method was applied in this study. Results: Gumpoong was testing of 4-yr-old specimens in 2002, the proportions of the below-groundroots that were rusty colored for Gumpoong was 1.29 in Daejeon and 1.45 in Eumseong, whereas theproportions for its yellow berry variant were 2.60 and 2.45 in the two regions, respectively. Thus theGumpoong was resistant to root rust. Sunpoong has a high yielding property. Its average root weight is70.6 g for 6-yr-old roots. Its yield is 2.9 kg/1.62m2 and the rate of heaven- and earth-grade product is20.9%, which is very high compared to 9.4% for Yunpoong. Sunone is resistance to root rot and thesurvival rate of 4-yr-old roots was 44.4% in 1997, whereas that of the violet-stem variant landrace was21.7%. Sunhyang has content of arginyl-fructosyl-glucose (AFG), which produces the unique scent of redginseng, is 95.1 mmol/g and greater than the 30.8 mmol/g of Chunpoong in 6-yr-old plants. Sunun andCheongsun are being nurtured to protect genetic resources. Conclusion: Developed ginsneg varieties will be used as the basis for the protection of genetic resourcesand breeding. Jang-Ho Lee

모 제약회사 근로자들의 직업성 천식 유병률과 약제 분말 노출수준

오성수,최용휴,김은아,이영목,장재길,유장진,박승현,김태균,정수영,김규상,강성규 大韓産業醫學會 2006 대한직업환경의학회지 Vol.18 No.2

목적: 제약회사에서 직업상 천식의 유병 규모를 파악하고 작업공정에 대한 작업환경 측정을 통해 제약회사의 약제 분말에 대한 노출수준을 평가하고자 하였다. 방법: 제약회사에서 약제 분말에 노출되는 근로자를 대상으로 천식을 선별하기 위하여 설문조사 및 진찰, 혈액검사, 폐기능 검사 그리고 피부단자시험을 실시하였고, 각 부서별 공정에 따라서 총분진과 항생제 또는 효소제 분말에 대한 작업환경 측정을 실시하였다. 직업상 천식이 의심되는 근로자에 대하여 기관지과민성에 대한 검사(메타콜린을 이용한 비특이 기관지유발시험)와 약제 분말 기관지유발시험을 실시하여 확진하였다. 결과: 설문조사 및 진찰에서 작업 관련 천식 증상이 있는 근로자는 11명(34.4%)이었고, 약제 분말을 이용한 피부단자시험에서 1+ 이상 반응을 보인 근로자 10명(31.2%)이었다. 비특이 기관지유발시험 결과 8명(25.0%)이 양성(PC20 ≤16 mg/ml)이었다. 약제 분말 기관지유발시험을 통해 직업상 천식으로 확진된 근로자는 5명(15.6%)이었다. 작업환경 측정에서 원료를 충진하거나 투입하는 작업 그리고 정립작업에서 약제 분말에 대한 노출이 많았다. 결론: 제약회사에서 직업상 천식은 주로 제조공정 중 약제 분말에 노출된 근로자에서 발생하여, 증상 및 직업성 천식의 유병률이 높았다. 따라서 원료를 충진 또는 투입하는 작업과 정립작업 등 제조과적에서 약제 분말 노출을 줄이기 위한 세심한 주의가 필요하여, 약제 분말을 취급하는 근로자에 대해서는 천식 증상 조사뿐 아니라 정기적으로 피부단자시험, 비특이 기관지유발시험 등을 실시하여야 할 것이다. Objectives: After the investigation of one worker with occupational asthma, we surveyed the preva- lence of occupational asthma and the exposure level of pharmaceutical dust of 32 workers in a pharmaceutical company. Methods: Thirty-two of the 90 employees participated in the survey which consisted of questionnaire, blood sampling, spirometry and skin prick tests with 8 common allergens as well as 9 antibiotics and 2 enzymes. Various indices of the working environment were also measured. Subjects who had a symptom suggestive of work-related asthma or positive skin prick test were further investigated by PC20 methacholine. Nine subjects who had a PC20 result of 16 mg/ml or less (n=7) or had work-related symptoms and positive skin prick test (n=2) were referred to undergo a specific bronchial provocation test to phar- maceutical dust in an academic allergic disease center. Results: Eleven of 32 workers (34.4%) had a work-related symptom suggestive of occupational asthma. Ten (31.2%) showed positive skin prick test. 8 (25.0%) had a PC20 result of 16 mg/ml or less (indicative of significant bronchial hyperresponsiveness), and 5 (15.6%) had a positive result on the specific bronchial provocation test. Exposure levels of stuffing, input of raw materials and screening process were relatively high. Conclusions: This survey showed that pharmaceutical workers have an increased risk of occupational asthma. Although pharmaceutical factories maintain a relatively good working environment, careful control of respiratory tract exposures, especially during stuffing, input or raw materials and screening process, is important to prevent occupational asthma. Pharmaceutical workers need to undergo regular skin prick and methacholine bronchial provocation tests, as well as asthmatic symptom survey, to ensure the early detection and prevention of occupational asthma.

This study was investigated the application and kinetics of biofiltration using cometabolic process to remediate gaseous toluene that are highly recalcitrant to adsoption and biodegradation. Biofiltration was successfully applied to treat amixture of volatile organic compounds(Toluene) from contaminated air stream. Immobilized Ps.oleovorans biofilter was evaluated for its value in simultaneous removal of Toluene from waste air stream. In the loading rate (1,000ppm) and space velocity(1,200hr). the average removal efficiencies of Toluene were 33.7%. and CO2 production rate were 5.28㎎/hr

This research is aimed at the development of Long Life Housing, which can realize sustainable construction and environment. It also promotes practical use of Long Life Housing with evaluation of the field application through Mockup House. This research is one of the important tools to realize Long Life Housing and deducts various traditional design's element technology to cope with demands of change of life cycle and style of residents. this study set three elements of plans for modernization in the traditional design factors that opening, wall and bottom as space composition elements of interior facts. first, Jang-ji wall and storage wall system separated from elements of wall that applied modernize elements of the wall. second, element of opening was restructure swing-lift-up opening system into modernize. third, maru and toet-maru system separated from elements of bottom that was applied modernize elements of the bottom. each elements segregation with four types as basic type, separate type, movable type and mixed type. This research make a proposal of plans for modernization in the traditional design factors, aimed at Long Life Housing through these four types blend. In addition, it points to promote realization of the sustainable 'Korea-style Long Life Housing' through modernization.

A synchronous generator is equipped with an automatic voltage regulator(AVR), which is responsible for keeping the output voltage constant under normal operating conditions at various levels. The output voltage of Synchronous Generator is regulated constantly by field voltage control in excitation system. High frequency PWM converter (Buck converter) type excitation system for synchronous generator that can sustain proper output voltage level even at the fault condition happened. The proper operation of the proposed excitation system was verified through the simulations and the experiments.

Public perception concerning water fluoridation and influencing factors were assessed. A mailing survey was conducted in 1999 with a representative sample of the general Seoul citizen (response rate=40.1%), who consisted of 1108 adults aged between 20 and 78. The data were analyzed using the chi-square test and structural equation modeling. 48.3% favored and 11.4% opposed water fluoridation while 40.5% were not certain. The contact on information about water fluoridation was the most significantly influencing factor on the perception concerning water fluoridation while experience of marriage, income and the perception of tap water were also significant. 52.8% expect governmental health authorities to take the decisions about water fluoridation.
