Traditional Industries were planning the major role for Taiwan's economy. However, we need to face the competition from developing countries. Moving manufacturing department to other low salary countries, such as China, can only temporarily release some limited pressure. The final and complete solutions are to equip on R&D, refine techniques, improve management capabilities, upgrade business, and reform physique. Currently there are some ERP systems on the market; however, they are designed for common purpose and difficult to introduce into industry. The expensive price is another factor to make them be popular. In this research we will Object Oriented, Visual Modeling, ER Model and Windows Environment to develop an Integrated Management System for Sports Requisites Industries (IMSSRI). We will integrate all information from all departments such as development, business, material administration, manufacture, shipping, and financial. When development people construct the all modules, components, cutting molds, materials and accessories, IMSSRI will calculate all needed materials and cost for each product. This cost will be used for quotation to report to our customers. When customers confirm the order, system will transfer all necessary materials into Material Administration System. IMSSRI can generate manufacturing forms and material raw lists for manufacture department. All related information such as stocking, returning goods, material requesting, and material returning can be integrated so we can control all details of the whole enterprise. Through the help of this system, we hope we can save man-power, reduce human mistakes, raise management capabilities for tradition manufacturing industries and create another possibility of eternal operating for Taiwan's Industries.

When a semiconductor package is assembled, various materials such as die attach adhesive, lead frame, EMC (Epoxy Molding Compound), and gold wire are used. For better preconditioning performance, the combination between the packaging materials by studying the compatibility of their properties as well as superior packaging material selection is important. But it is not an easy task to find proper packaging material sets, since a variety of factors like package design, substrate design, substrate size, substrate treatment, die size, die thickness, die passivation, and customer requirements should be considered. This research applies case-based reasoning(CBR) technique to solve this problem, utilizing prior cases that have been experienced. Our particular interests lie in building decision support model to aid the selection of proper die attach adhesive. The preliminary results show that this approach is promising.

General pharmacological properties of urinary trypsin inhibitor (UTI) following intravenous administration of 1,000,000 units/kg were examined in terms of effects on central nervous system, cardiovascular system, respiratory system, gastrointestinal system in mice, rats and rabbits. Administration of UTI (1,000,000 units/kg, iv) had no effect on central nervous system; no influences on pentobarbital sleeping time, spontaneous activity, normal body temperature, chemoshock produced by pentylenetetrazole solution, writhing syndromes induced by 0.6% acetic acid solution, and motor coordination of mice. The administration of UTI (1,000,000) units/kg, iv) in rats had no effect on systolic blood pressure and pulse rate. UTI (500,000 units/kg, iv) given to anesthetized rabbits showed no effect on respiratory rate. However, it showed significant elevation of respiratory rate at the concentration of 1,000,000 units/kg. Gastric secretion of rat and intestinal motility of mice were not influenced by the dose of 1,000,000 units/kg. In terms of autonomic nervous system, the material did not show direct effect and inhibitory or augmentative action of histamine- or acetylcholine-induced contraction at the concentration of 2,000 units/ml in the isolated ileum of guinea pig.

School food service must be operated as the part of the education. But it seems that it is not to be considered as an important educational field from the perspective of educational administration. This study was conducted to suggest the effective plan to improve the quality of the school food service system. Questionaries were distributed to 51 administrators and 85 dieticians of primary schools in Incheon area from Aug 7th to Aug 31st 2000. Drawbacks of school food service system cited from the survey results were insufficient support from the authorities both in policy and in budget and shortage of specialists for food service administration. Both dieticians and administrators acknowledged that available facilities required for the school food service were insufficient. 85.9% of dietition and 51.0% of administrators thought dietition of school food service to be suitable for nutrition education. For effective nutrition education, they suggest to have teachers taking in charge of nutrition education, to have teaching system related with school food service and to develope visual auditorial teaching material. For improvement of the quality of school food service, it is necessary to acquire sufficient budget and political support from the government and to have specialists for food service administration. And regulations promoting dieticians to be teachers of nutrition education is required to be introduced in the near future.

고삼추출물은 한국에서 유기농업자재로 등록되어 있어 친환경농산물 재배시에 널리 사용되고 있다. 고삼추출물의 유효성분인 matrine은 쥐의 신경계에 독성을 나타낸다고 보고된 바 있으나 다른 안전성 확인 연구는 미비한 상황이다. 따라서 본 연구는 고삼추출물 2종을 이용하여 항돌연변이원성 시험과 유전독성시험 2종(복귀돌연변이 및 염색체이상 시험)을 실시하였다. 항돌연변이원성 시험은 복귀돌연변이 시험방법을 이용하여 실시하였으며, 복귀돌연변이 시험으로는 Salmonella Typhimurium TA98, TA1535와 TA1537을 이용하여, S-9 mix를 사용한 대사활성계 처리군과 PBS를 사용한 대사활성계 미처리군으로 구분하여 진행하였다. 염색체이상 시험은 Chinese hamster lung cells을 이용하여 고삼추출물 시료에 대사활성계 처리군은 6시간 노출시켰고, 대사활성계 미처리군은 각각 6시간과 24시간 노출시켜 시험하였다. 항돌연변이 시험 결과, 4-NQO에 의해 유도된 돌연변이 집락수는 고삼추출물 시료 처리에 의해 감소되어 항돌연변이 효과가 있는 것으로 나타났다. 시험결과, 복귀돌연변이 시험에서는 고삼추출물의 모든 시험 농도군에서 대사활성계의 처리 유무와 관계없이 독성이 나타나지 않았다. 반면, 염색체이상시험 결과 고삼추출물 시료 1종에서 대사활성계 미처리군에서는 250 ${\mu}g/mL$, 대사활성 처리군에서는 500 ${\mu}g/mL$ 의 농도에서 의양성이 나타났고 이 이하의 농도에서는 모두 음성으로 나타났으며, 나머지 시료 1종에서는 모든 처리농도군에서 음성으로 판정되었다. 고삼추출물의 유전독성 가능성을 더 정밀히 평가하기 위해서는 향후 battery system에 포함된 다른 in vivo 유전독성 시험을 추가로 시행하여 유전독성 여부를 최종 확인할 필요가 있다고 판단된다.
