This study examined the menu management and utilization of cooking equipment at school foodservice operations in the Chonbuk area. Self-administered questionnaires were collected from a total of 193 school dietitians. Statistical data analysis was completed using the SPSS v. 11.5 program. The results are summarized as follows. Among the 193 schools, 58.5% were elementary schools and 41.5% were middle and high schools. Approximately 97% of the schools prepared meals in the conventional manner. Among the school, 68.4% had a menu cycle of 1${\sim}$2 weeks. The frequency of using convenience foods was significantly different between the elementary schools and middle and high schools(p<0.001). Approximately 45% of the dietitians responded that the most important details for menu planning were menu variety and consumer preference. However, 66.8% of the dietitians responded that a key problem for menu planning was limited and worn-out kitchen equipment. Although the cost of purchasing cooking equipment is high, most dietitians responded they have high needs for equipment in order to meet of the quantity demands of food production. In terms of utilized cooking equipment, most schools had mixers, vegetable cutters, choppers, dish washers, etc. Yet the amenities most often lacking were meat slicers, composting machines, ovens, and griddles. In utilizing the cooking equipment, there was no significant difference between the dietitians in the elementary(3.67) schools and those in the middle and high school foodservice systems(3.70); however, the utilization level was poor. Therefore, governmental regulatory agencies should review and finance support for purchasing cooking equipment. Finally, purchasing analysis was conducted regarding the dietitians' opinions on menu recipes and useful equipment.

The purpose of this study was to determine the difference between estimated profit and utilization of medical equipment upon purchasing and actual results at one teaching hospital in Seoul, Korea Medical equipments over $100,000 from 1992 to 1997 were selected and results were as follows: 1. Twenty equipments out of thirty exceeded estimated profits and the difference was 3.98 billion won and ten equipments did not reach the estimated profits and 5.5 billion won was the difference. Diagnostic equipment exceeded the estimated profit which surgical equipment didn't. 2. Eleven equipments exceeded estimated utilization, which showed 100%. In the mean time, eighteen equipments didn't reach the estimated utilization, which was 71%. Diagnostic equipment showed the less estimated utilization than surgical equipment 3. Twenty-one equipments showed the 6.83 billion won profits and nine equipments showed the 1.6 billion won deficits. Diagnostic equipment was more profitable than surgical equipment. Finally. diagnostic equipment helped improving hospital management than surgical equipment. 4. Main factors which showed the big difference from the initial plan were lacking reasonable estimated method, no evaluation system for purchase, emphasis in medical treatment, excessive expenditure in maintenance, duplicated investment for medical equipment and leadership commitment. As a result. Substantial planning is required from the requesting department in consideration of estimated profit and utilization and systematic quality control is needed to confirm. Also, One-sided decision making should be avoided to purchase a high cost medical equipment and efforts should be made in examining carefully and developing a reasonable analytic method.

industry each which are using a kind of EDI, supplier-oriented Electronic Data Interchange(SOEDI) to procure materials, equipment and supplies more effectively. The major objective of this study are to determine the basic nature of the impact of SOEDI on the structure and procedure in purchasing. The other is to identify the variables or determinants which influence the benefits which can be experienced in purchasing organizations. This study was conducted through interviewing of organizations which are currently active in the use of EDI. Samples of 107 purchasing organizations were collected. Some key findings of this study are ; 1) There were remarkable differences on influencing level and relationship of determinants which influence the benefits of purchasing organizations. There was the most remarkable one in trading industry. 2) The more suppliers, the more benefits. The transaction rate with suppliers who are affiliated with EDI is low as a whole but suppliers who are affiliated with EDI can be a critical factor on selection of buyers. 3) Procedure related to purchasing order was mainly changed. There is a development on signature but still exists. 4) The number of employees were reduced a little bit.

Manufacturing companies' cost competitiveness with respect to equipment management can be achieved by satisfying additional market demands by their own capacity without purchasing additional equipments. In essence, it can be accomplished by making continuous investigation into bottlenecks and improvement on them. Therefore, equipment performance measure systems should be designed so that they can support manufacturing companies' such endeavors. With the purpose of establishing an effective equipment performance measurement system for detecting and improving bottlenecks, this study (1) suggests some desirable features that such a system should have, (2) evaluates conventional equipment performance measurement systems in terms of their usefulness for the detection and improvement of bottlenecks, and (3) proposes an improved system. We also perform a simulation experiment to demonstrate the limitations of the conventional systems and show how the proposed system can resolve the problems.

CSP(Concurrent Spare Parts) is supplied with the procurement of new equipment or weapon system and is used to sustain the equipment without resupply during the initial coverage period. This study is concerned with a problem of determining the near optimal inventory level of the spare parts, especially Concurrent Spare Parts. For this, we utilize the mixed periodic and continuous review polices considering the CSP and (r,Q) Policies concurrently in a two-echelon distribution system. We propose the mathematical model to minimize the total cost which is composed with ordering cost, purchasing cost, holding cost, and stickout cost. If the mixed policy is compared to other policies(CSP, (r,Q)), the proposed methodology performs well and is best policy in the equipment maintenance expenses.

본 연구에서는 국내 콘텐츠 생산 및 유통방식의 급격한 변화에 따른 방송장비 구매 수요처의 절대적인 장비구매 인식을 비교하였으며 이에 수요자가 지각하는 국산 방송장비의 기술 신뢰도, 시스템 안정성 등의 정보의 정도가 장비구매에 미치는 영향을 연구모델을 통해 분석하였다. 방송 장비 수요에 관한, 기존 연구 데이터의 미진함으로 인하여 방송장비 전문가들과의 심층인터뷰와 설문조사를 병행하였다. 분석 결과로 외산장비에 비해 국내 장비의 단품구매와 시스템, Block구매의 경우가 많아 호환 경쟁력이 미흡하고 기술발전이 늦다. 국내 방송장비수요처가 인식하고 있는 국산방송 장비에 대한 선호, 만족도의 향상을 기하기 위한 기술 신뢰도 증진과 핵심 주요장비의 개발이 시급하며 소출력 송신기 안테나, 모니터장비에 국한되어있는 국산 장비의 공급을 확장하기 위한 개발이 시급하고 해외진출과 시장을 확보하기 위한 국내육성 지원도 요구된다.
