미래 사회를 대비하기 위한 개인의 개성을 존중과 창의적인 능력을 지닌 인간을 양성을 목적으로 충청남도 지역의 초 ㆍ 중고등학생들을 대상으로 한 창의력 경연대회가 공주대학교 과학교육연구소에서 개최되었다. 충청남도 초 ㆍ중 ㆍ 고등학생들을 대상으로 실시한 창의력 경연대회는 창조적 아이디어를 내어 스스로 문제를 해결해 나갈 수 있는 교육 프로그램을 제공하는 좋은 기회였음이 확인되었으나, 일부의 팀에서만 참신하고 재미있는 아이디어들이 제안되었다. 여학생의 참가자 수가 상당히 증가하였으며, 대체적으로 입상권의 학생들의 상당 부분이 여학생이라는 것이 특이할만하다. 학년이 올라감에 따라서 창의적인 아이디어를 내는 양이나 질에 있어서 뒤떨어지는 것으로 분석되었으며, 토론 학습의 적응력이 미흡하고 발표력 및 청취력에 있어서도 떨어지는 것으로 나타났다. 따라서 중 ㆍ고등학교의 학교교육에서도 학생들에게 프로젝트형 탐구학습 프로그램의 적용은 물론 토론식 수습을 통한 학생들의 사고의 전환의 기회를 제공해야 할 것으로 사료된다. The creativity competition was held to foster the creativity of elementary and secondary school students in the Institute of Science Education, Kongju national University. It was found that the creativity competition effected on the improvement of inventing creative ideas and problem solving activities. But, only some competitors participated in semifinal and final contests, presented original and interesting ideas. More female students participated in competition than last year. More female participants were awarded a prize than males. Totally, participants were defective in discussion and communication, and presentation and listening ideas. Increasing grades correlated inversely with creativity and originality. There is need of inquiry project teaming programs and presenting opportunities of conversion of thinking by discussing instructions in school

These day, Internet Recruiting needs the negotiation of recruiting items. This paper proposes multilateral negotiation that substitutes applicants and employers. Previous Negotiation Systems use the preference value of the multi-attribute and the sequential negotiation. But proposed Internet Recruiting Negotiation System(IRNS) uses the parallel negotiation of multi-attribute. The parallel negotiation supplies the multi-attribute negotiation including values of single-attribute and result of parallel negotiation. This paper shows that excellent result for effective negotiation using the weight strategy of multi-attribute for a matter of concern of users.

광주시내 업종별 음식점의 주방기구와 관련된 주요 세균 및 이들의 계절별 변화

이홍열,유맹자,정해진,김근영,정희종 全南大學校 農業科學技術硏究所 1998 農業科學技術硏究 Vol.33 No.-

업종별 음식점에서 사용중인 주방기구 가운데 개숫물중에 존재하는 세균들을 분리·동정한 결과, 한색음식점에서 37균주, 일식음식점에서 23균주, 및 중식음식점에서 33균주가 분리되었고 이들 중 한식음식점에서 E. coli 등 16균주, 일식음식점에서 Listeria sp. 등 20균주, 중식음식점에서 Micrococcus sp. 등 15균주를 각각 동정하였다. 이들 세균들은 업종별 음식업소에서 주로 사용되는 색품재료에 존재하는 세균들과 밀접한 관계가 있는 것으로 밝혀졌고 E.coli와 같은 일부 세균들은 주방의 불결한 환경이나 종사자로부터 오염된 것으로 추정되었다. 업종별 음식점에서 사용중인 개숫물, 행주, 칼, 및 도마에 존재하는 세균의 분포는 일반세균수 및 대장균수가 모두 2월에서 8월까지 점점 증가하다가 11월에는 다시 감소하는 경향을 보였다. 특히 이같은 경향은 일반세균은 개숫물에서 대장균군은 칼에서 가장 뚜렷하게 나타났다. 따라서 식중독 발생 가능성이 가장 높은 여름철에는 칼, 도마 등 주방기구들은 정기적으로 열탕소독하는 철저한 위생처리가 필수적인 것으로 생각되었다. Thirty-seven, twenty-three, and thirty-three bacterial strains were isolated from dish-washing water which was selected as a kitchen supply commonly loaded the highest level of bacteria among various supplies using at Korean style, Japanese style, and Chinese style restaurants. Among these isolates, sixteen strains including Esherichia coli, twenty strains including Listeria sp., and fifteen strains including Micrococcus sp. were identified from Korean style, Japanese style, and Chinese style restaurants, respectively. This result suggested that most isolated bacteria were closely related to bacterial flora of raw food materials used in each style of restaurants and others could be contaminated from the surrounding environment and the employees. Total and coliform bacterial counts distributed in dish washing water, wiping cloths, knives, and cutting boards used at different types of restaurants were gradually increased from February to August and then decreased until November. This changing tendencies of total bacterial counts and coliform group counts were obvious in dish-washing water and in knives, respectively. Therefore, kitchen supplies such as wiping cloths, cutting boards, and knives should be treated carefully with hot water of above 45℃ at every certain period of time to kill some of these potential hazardous bacteria and to prevent outbreaking foodborne-illness by them, especially during Summer.

대장균군 검사용 간이 시험지는 본 실험실에서 국내 최초로 고안, 개발하였으며 이 간이 시험지법은 현장 검사법의 하나로 대장균군이 내는 succinic acid dehydrogenase 때문에 tetrazolium salt 가 환원되어 적색 반점을 형성하는것을 이용한 방법으로서 이 간이 시험지의 제조는 대체로 종래의 표준 평판법과 거의 동일한 조성의 배지와 시약을 사용하여 여지에 흡착시킨 후, 건조시켜 (60℃) 멸균한 것으로 표준 평판법과 어떤 상관관계가 있는가를 검토하였다. 이 간이 시험지의 제조에서는 bile salt No. 3를 deoxycholate로 대체하여 제조 원가를 절감하였고, 또한 일본에서 현재 시판되고 있는 제품과 품질 비교시험을 하여 더 좋은 결과를 얻었으며 종래의 표준 평판법과 비교하였을 때도 오히려 표준 평판법(24-48시간 배양)보다 빠른 시간(16-20시간 배양)내에 판정할 수 있는 이점이 있으며, 표준 평판법에서는 없어서는 안될 배지나 배양 접시, pipette등의 자료및 기구가 일체 필요없고 언제 어디서나 현장에서 직접 시험할 수 있어 매우 간편하며 또한 저렴한 가격으로 제조할 수 있는 경제성이 높은 이점을 갖고 있다. The objective of this study was to develop a paper strip which could determine E. coli qualitatively and quantitatively in water, wastewater, drinks, or food. This paper strip method was a simple and rapid test method that determine E. coli by visual identification. In this study, nutrient culture media were formulated and characterized for optimum conditions. Paper strips were then prepared by impregnating into the media and dried at 60℃. The test procedure is quite simple to use. The paper strip was dipped into a sample, and excess sample was removed. The strip was then incubated at 37℃ for 16 to 20 hours and the number of colonies on the strip was counted. The color of the colony spots produced by microorganisms varied depending on the media formulation. Violet-red spots were produced by E. coli. The test method was simple, rapid and no special laboratory equipment was necessary for visual identification. Therefore, this test method is applicable to on-site tests such as field tests or home tests. The paper strip method was compared with the standard agar plate method and Japanese commercial product. The method of the economical preparation of test strips was studied for production on industrial scale.

광주시내 업종별 음식점의 위생상태 및 식중독원인 세균의 분포 특성

업종별 음식점 주방의 위생상태는 일식>중식>한식의 순이었고 개인위생의 경우는 일식>한식>중식의 순이었는데 주방 및 종업원의 위생상태를 향상시키기 위해서는 음식점 규모의 대형화, 45℃ 이상의 온수공급, 주방시설의 표준화, 위생비닐장갑의 착용, 및 유니폼 착용이 신속하게 이루어져야 할 것이다. 업종별 대중음식점의 주방기구중의 세균분포는 전반적으로 일반세균수가 높게 나타났고 특히 대장균군수가 높게 나타났는데 음식물이 아니고 조리기구이긴 하지만 우리 음식점의 위생상 문제가 많은 것으로 생각된다. 미국 육군 Natick연구소가 제시한 음식물의 미생물 기준한계인 1 ×10??마리 이하, 대장균수가 100마리 이하와 비교할때 일반세균수의 경우는 아주 만족할만한 위생상태로 평가되었으나 대장균수는 개숫물의 경우 업종과 관계없이 높게 나타났고 행주와 칼의 경우 일식음식점에서만 높게 나타났으며 도마의 경우는 모두 100마리 이하로 양호한 위생상태로 평가되었다. 한식 전문음식점간의 세균수가 큰 차이를 보인 것은 규모와 운영방법이 서로 다르기 때문으로 앞으로 한식음식점에 대한 시설 및 환경개선에 대한 노력이 요구되었다. 또한 일식음식점간에는 일반세균수의 분포가 크게 다는 것으로 조사되었는데 특히 개숫물, 행주 및 도마중에 존재하는 미생물수가 크게 차이가 있었다. 등급별 한식음식점의 세균분포는 호텔급 음식점> 일반대중급 음식점> 여관급 음식점의 순으로 나타나 업소규모가 클수록 위생시설 및 위생습관의 수준이 높아 위생상태가 양호한 것으로 분석되었고 여관급음식점의 경우 위생상태가 낮은 것은 이용빈도가 낮은 것이 그 원인이 아닌가 생각되었다. Sanitary evaluation of kitchen area in different types of restaurants was the best at Japanese style restaurants and the worst aat Korean style restaurants. In personal hygiene Japanese style restaurant were evaluated as the best, but Chinese style restaurants were evaluated as the worst. Total and coliform bacterial counts were mostly showed high levels at all types of restaurants and especially this tendency was predominated in coliform counts. As compared to the standards suggested by U.S. Army Natick, however, total bacterial counts in all of supplies were evaluated as the satisfactory state. On the other hand, coliform counts in dish-washing water were much higher than the standard, which were not affected by the types of restaurant, and Japanese style restaurants were higher in wiping cloths and knives, but cutting boards were evaluated as satisfactory state with the counts less than 1.0 ×10².Bacterial counts in Korean style restaurants were greatly different depended on the size or type of restaurant. Total bacterial counts in Japanese style were also different among restaurants, especially in dish-washing water, wiping cloths, and cutting boards. According to the results of the evaluation of Korean style restaurant, bacterial distribution based on the class of restaurants, classified as hotel, motel, and public classes, hotel class restaurants showed lower levels of bacterial counts than public class. This result suggested that the larger and higher classes of restaurants maintained the satisfactory state without potential hazards.

The transplantation of organ, tissues or cells between individuals of different species has been of increasing interest in recent years because the use of animals as organ and tissue donors as a source of transplants would overcome the severe and worsening shortage of human organs available for transplantation. However, There are some major hurdles to the clinical application of xenotransplantation; the immunologic response of the recipient against donor, the physiology of the graft, and the possibility that a xenotransplant might transmit an infection from the source to the recipient. This review describes the unique aspects of the immunological barrier to transplanting organs from non-primates such as pigs into humans, focusing especially on the mechanisms which contribute to immunorecognition, physiology of the rejection and infectious hurdles to xenotransplantation. This communication might be applied to overcoming these hurdles and the possibility that genetic strategies might be used to expand the potential applications of xenotransplantation for the treatment of human disease.

Objectives : This study was designed to develop and standardize a checklist for ergonomic risk factors, and to provide ergonomic guidelines for managing cumulative trauma disorders (CTDs) in automobile assembly lines, Methods : The Checklist for Ergonomic Risk Factors(CERF-1) was developed based on the results of previous studies, and then modified after performing pilot study. Information on the symptoms possibly related with CTDs was obtained using a self-reported questionnaire from 465 automobile assembly workers. Their job conditions were examined to assess risk factors through both direct observation and video analysis. Results : Rate of detecting risky job through CERF-1 was 85.6%, and was similar to that (88.8%) by Occupational Safety and Health Adminstration(OSHA) checklist but higher than that (63.7%) by American National Standards Institute(ANSI) Z-365. Relationship of the exposure scores derived from CERF-1 with levels of symptom was greater (r=0.49) than OSHA(r=0.28) and ANSI Z-365 (r=0.22). Considering the relationship, jobs scoring higher than 16 could be classified as the Risk Job, and lower than 16 as then Low Risk Job. Sensitivity and specificity of the Risk Job were 92.5% and 31.5 %, respectively. Odds ratio (OR) after age adjus-tment was 5.69 (95% confidence interval 3.15-10.29) for the Risk Job, and these ORs were significantly different from those of the Low Risk Job. The exposure scores were quite valid, in that the scores at the main survey were significantly correlated with those at the follow-up survey, as suggested by test-retest(r=0.88) and inter-rate reliability(r=0.80) Conclusions:The CERF-1, developed in this study, will be an efficient tool for evaluation of risk jobs for CTDs in automobile assembly lines, and can be used easily by health care providers.
