본 연구에서는 복층유리 보온효율의 바로메터가 되는 열전도도의 정확한 측정을 위하여 복층유리의 열전도도 측정장치를 개발하고 이 측정장치에 대한 이론적인 모델을 제시하였다. 또한 이를 이용하여 다양한 복층유리에 대한 열전도도를 측정하였다. 열선을 장착한 복층유리의 경우 열선에 가한 전류의 증가에 따라 열전도도가 지수함수적으로 감소하였다. 판유리 및 공기층의 두께에 따라 다양한 복층유리가 생산되고 있으며, 본 연구에서는 유리의 두께를 일정하게 두고 공기층의 두께를 변화시키며 열전도도를 측정하였다. 공기층의 두께가 증가함에 따라 복층유리의 열전도도는 지수함수적으로 감소하는 것으로 나타났다. In this study, an apparatus for measuring thermal conductivity has been developed to accurately measure the thermal conductivity of pair glass, which is a barometer for efficiency of keeping warm, and the theoretical model for the apparatus was suggested. Then the conductivities of various pair of glasses were measured by using this equipment. The thermal conductivities of the pair glass in which the warm wire was installed decreased exponentially as the applied current increased. For the test fixing the thickness of glass in pair glass and varying the thickness of air layer, the conductivity also decreased exponentially as the air layer thickness increased.

기존의 특수건강진단과 작업환경측정을 통한 직업병 관리가 진폐증, 소음성난청 등의 소수 특정질환에 국한되고 실제 직업병 발생 규모 파악이나 신종 직업병의 발견에 한계를 보인다는 사실은 산업의학전문가들 사이에서도 공감을 이루고 있다. 미국과 영국 등에서의 직업성질환 감시체계에 대한 경험은 우리 나라의 직업성질환 감시체계 구축에도 새로운 자극제가 되면서, 1998년이후 인천, 대전, 여천, 구미, 부울경 지역에서 지역 직업성질환감시체계를 산업보건관리의 중요한 시스템으로 구축하려는 노력이 확산되고 있다. 새로이 구축되어지는 이들 지역 직업성질환 감시체계는 감시하고자 하는 대상질환, 활용 가능한 인적자원 및 자료원, 지역 의료체계의 특수성 등에 따라서 목적과 방법을 달리하면서 독특한 형태로 발전을 하고 있다. 각 지역단위 감시체계들이 그 상황에 맞게 독특한 목적과 전략들을 발전 시키면서도, 향후 발전할 국가적인 차원의 직업성질환 감시체계 구축을 위하여 직업성질환 감시의 기본 전략 등을 공유하는 등의 노력이 필요하다. 환례 정의 및 기본적인 등록 서식의 공유, 직업성질환 감시 자료원의 발굴, 공동의 정보 네트워크 및 직업성질환 감시 데이터베이스 구축 등 직업성질환 감시활동을 지원하기 위한 여러 기초 인프라 구축에 힘을 모아야 할 것이다. 우리 나라에서 직업성질환 감시체계를 성공적으로 구축하기 위해서는 수집된 자료의 질 관리를 위한 직업성질환 감시의 원칙 제정과 감시 전략의 공유 등이 필요하며, 전국적인 직업성질환 감시체계의 하부구조라고 할 수 있는 지역감시체계의 기초 토대 마련과 강화작업이 절실하게 필요하다.

This study was carried out to analyse the vitamin C content in vitamin supplements by the HPLC method. The product types were chewable tablet, tablet and powder. After purchasing, three types of vitamin supplements were stored at two different temperatures; -18 ℃, and ambient temperature. Vitamin C content were determined by two different HPLC operation conditions: at 1^(st) experiment, Waters 600E system with Nova-Pak C_(18) column were used; and the 2^(nd) experiment was done with Shisheido Nanospace 51-2 with Capcell pak UG80 C_(18) column. As the result, vitamin C contents at 1^(st) and 2^(nd) experiments, expressed as the ratio of determined to declared amounts were estimated 1.09~1.98 times and 1.30~2.34 times more than the declared amount at -18℃ , respectively. At ambient temperature, the vitamin C contents were 0.99~l.86 and 0.82~l.85 times higher than the declared amounts at the 1" and 2f experiments, respectively. The ratio increase at -18℃ were not so much as at ambient storage. However, both at -18 ℃ and ambient storage, the determined amounts of vitamin C were more than the declared amount. In conclusion, vitamin C was intaked more than RDA as well as the amount of vitamin C including its dietary intake was more than 1,000 ㎎/day in some vitamin supplements according to their own direction and/or dosage indicated.

제주항의 Vibrio parahaemolyticus 분포에 관한 연구

김재하,오덕철 제주대학교 해양연구소 1982 해양자원연구소연구보고 Vol.6 No.-

A survey of Vibrio parahaemolyticus distribution in Jeju harbor was carried out semimonthly for eight different sites from June to October 1981. The place shown the highest count was site 6 and site 7 while the lowest count was shown at site 8. In terms of season, August and September showed the highest while considerably low counts were shown in July and October. Regardless of seasons and sites. overall counts were within the range of 100/100ml~3000/100ml. Lower counts were shown in comparison with other coastal areas such as Busan, Masan and Ulsan harbor. Certain correlation was observed between counts and water temperature while no correlation was found with pH. It could be health hazardous to use untreated water and raw fishes caught from surveyed area in neighboring restaurants.

가정에서 제조된 재래식 된장, 간장, 고추장 중에 존재하는 Ochratoxin A의 효소면역분석법에 의한 잔존량 분석

본 연구에서는 재래 방법에 따라 생산되고 있는 전통발효식품(된장, 간장, 고추장)에 함유되어 있는 Ochratoxin A(OT-A)를 면역학적 정량분석법인 Enzyme-Linked Immuno-sorbent Assay(ELISA) 법을 개발하여 분석하였다. 각 가정에서 생산하여 소비되는 장류 즉, 된장 13종, 간장 12종, 고추장 14종을 전국적으로 수거하여 분석을 실시하였다. OT-A를 정량 조사한 표준곡선의 작성 결과 ELISA 방법의 sensitivity는 20pg/assay 이었으며, 본 실험에서 사용한 면역분석법의 OT-A 회수율은 90%이상이었다. OT-A의 잔존량은 가정에서 생산하여 소비되는 된장이 7.1±3.7ng/g, 간장이 2.1±2.6ng/g, 그리고 고추장이 4.0±1.9ng/g이었으며, OT-A에 대한 오염도가 비교적 낮은 것으로 나타났다. 한편 OT-A의 가열안정성 시험에서는 60, 90, 120℃에서 120분까지 가열 처리하여 OT-A의 잔존량을 조사하였던 바 121℃의 고온에서 120분까지도 안정하였다. This study was undertaken to develop the analytical procedures, Enzyme-Linked Immunosorbent Assay(ELISA) for the quantitative detection of ochratoxin A(OT-A) in the home-made 13 Doenjang, 12 Kanjang, and 14 Gochujang collected throughout the country. The detection limit in ELISA was leveled as low as 20 pg/assay, and that the OT-A recorvery rates from sample clean-up were appeared to be more than 90%. Therefore, ELISA was the appropriate tool to detect the residual OT-A in the traditional fermented foods. The residual contents of OT-A in the home-made traditional fermented foods were 7.1 《3.7 ng/g for Deonjang, 2.1《2.6ng/g for Kanjang, and 4.0《1.9ng/g for Gochujang. Comparatively it was low,and OT-A seemed to be carried over Doenjang to Kanjang from Meju. At heating stability test of OT-A in the traditional fermented foods was it found to be stable even at 121℃ for 120 min.

The effects of chitosan on the germination and growth of mungbean sprouts were investigated on a laboratory scale. Mungbean was separately imbibed in 500 and 1,000 ppm chitosan solutions for 7 hrs followed by sprinkling with distilled water, and the other mungbean was also soaked in 500 ppm chitosan solution followed by sprinkling with 500 ppm chitosan solution, and then kept at 25±1℃ for 5 days. The growth characteristics such as whole length, hypocotyl length and thickness, root length and hair, and sprout yield were maintained and increased in the chitosan-imbibed mungbean. As mungbean grew, the proximate components such as carbohydrate were almost catabolized in the chitosan-imbibed mungbean sprouts during germination. The growth rate of sprouts expressed as whole length per day was comparatively higher in the chitosan-imbibed mungbean. One of the important enzyme during germination, α-amylase, increased its activity until the 4th day and thereafter slowly decreased except 500 ppm chitosan-sprinkled mungbean sprouts showing the lower response in its activity. Consequenctly, when mungbean imbibed in chitosan solution was cultivated, the chemical composition of the resultant sprouts did not change but their growing characteristics and sporut yield were enhanced as compared with others. Therefore, chitosan treatment during the imbibition of mungbean is potential to activate the growth of mungbean but decrease it when sprinkled with chitosan solution.

This study was done to review the prospects of doobu industry and its growth trend for the near future. Every aspect of doobu industry associated with production, distribution, sale and consumpton was evaluated in detail, which was used to help identify the comfronting problems at any stages of the whole doobu production chain. Once identified, means of improving the adequacy of control were assessed including physical, chemical, microbiological, informational or administrative factors. In order for doobu industry to realize its full potential from now on, the following possible remedies were strongly recommended: (1) increase in domestic soybean production and supply; (2) processing improvement in doobu production; (3) enhancement of microbiological quality control; (4) diversification of doobu products including their secondary products; (5) development in cooking and packaging methods; and (6) continuous infomation and advertisement as health food. It is necessary to put them together as a whole, rather than having isolated at each of the steps involved in doobu production and use. These remedies should interrelate and interlock so there is no way the whole system can go out of control.
