This study examines the relative efficiency of 34 local public medical centers in Korea. In order to concretely grasp the causes of inefficiency and suggest improvement solutions, the desirable set point was established based on the actual value which needs to be improved. As a result of analysis, we determined that output must be increased while input is held constant in order to improve effectiveness through the actual value and set point. Efficiency cannot be achieved if input is augmented solely to increase output. Also, to increase output, the medical centers need to improve their quality without increasing any input for customer visits and hospitalizations. Further, in order to strategically promote effectiveness and efficiency of local public medical centers, these medical centers must focus on input resource and patient interchange through the mutual cooperation with local private hospitals and university medical centers.

We consider a supply chain model with a make-to-order production facility and a single supplier. The model we treat here is a special case of a two-echelon inventory model. Unlike classical two-echelon systems, the demand process at the supplier is affected by production process at the production facility as well as customer order arrival process. In this paper, we address that how the demand variability impacts on the optimal replenishment policy. To this end, we incorporate Erlang and phase-type demand distributions into the model. Formulating the model as a Markov decision problem, we investigate the structure of the optimal replenishment policy. We also implement a sensitivity analysis on the optimal policy and establish its monotonicity with respect to system cost parameters.

It is booming to use computer and information owing to the information society. As software applications have grown, so too has the importance of software quality. Therefore, software quality measurement and evaluation are necessary to satisfy the users who are using computers. The ISO/IEC 9126 defines six quality characteristics and twenty-one subcharacteristics including forty inter quality characteristics. We developed software measurement and evaluation technique using the check list in accordance with the ISO/IEC 9126 in design phase. We applied idea and concept of Total Quality Management in order to evaluate and measure the quality of software. Namely, it is the concept such as "you should do it right the first time." or "you have to build quality in the process." We executed the quantitative evaluation of software, also had shown the distinctive result in order that users and developers can find the errors easily. We evaluated the quality of academic softwares in order to verify developing technique at S college. As a result of the evaluation, this college has found it necessary to maintain the software as soon as possible because academic systems are not adequate for users at this present time.

This paper proposes a framework for product development including hardware and software components. The framework provides separation of the hardware dependent software, an integrated product development process, and integration of software components with product configurations and product structures. In order to separates the hardware dependent software, the framework considers product configuration modules and engineering changes of associated hardware and software components. The proposed product development process integrates development of the hardware dependent software into the existing product development process. In order to integrates the hardware dependent software with product configurations and product structures, the framework represents software components by existing product data models in Product Data Management (PDM). The framework is applied to development of a robot system including hardware and software components in order to show its effectiveness.

The purpose of this study is to find out the residents' attitudes for the shared community space (SCS) according to various housing sizes (60㎠, 85㎠, 102㎠, 135㎠). The major findings are as follows: 1) The residents' overall trends for the SCS showed that the satisfaction rate and requirement rate according to housing size didn't show a significant difference, but there was a considerable difference among the using rates for each category of housing sizes. 2) The kinds of common facilities that residents required were recreational facilities, car-wash facilities, children's play centers, facilities for separation/sanitation for garbage and recyclable materials and lounging facilities in that order. The common facilities that require tenant-management were recreational facilities, car-wash facilities and lounging facilities in that order. The common facilities that require participation in tenant-management were study/reading facilities, recreational facilities and hobby/lecture facilities in that order. 3) With regard to the residents' needs, the tenant-management and participation in it, the kinds of common facilities were differentiated according to housing size (60㎠, 85㎠, 102㎠, 135㎠).

This paper proposes a product data model that can express and enforce integrity constraints on product structure during engineering changes (ECs). The model adopts and extends an active object-oriented database model in order to Integrate IC data and their integrity constraints. Tightly integrated with product structure, It will enable designers to maintain and exchange consistent EC data throughout the product life cycle. In order to properly support operations for ECs, the model provides the data, operations, and Event-Condition-Action rules for nested ECs and simultaneous EC applications to multiple options. in addition, the EC objects proposed In the model integrate the data and Integrity constraints into a unified repository. This repository enables designers to access all EC data and integrity constraints through the product structure and relationships between EC objects. This paper also describes a prototype product data management system based on the proposed model In order to demonstrate its effectiveness.

We identified the intake pattern and consumption propensity of milk and sought improvements to promote consumption of milk. We targeted 362 preschool children aged 5~7 years old who attended nursery school in the Bucheon area. Questionnaires were distributed and 328 questionnaires were collected. Approximately 36.2% of boys and 31.2% of gorls drank milk six times per week. A total of 32.9% of the preschool children drank more than 2 cups of milk/day. Approximately 72.9% of them currently drink white milk, and 46.0% preferred milk to processed milk. The reasons why they drink milk included 'want to be tall'(66.5%) and 'good health'(52.4%). Mothers(54.6%)and preschool children(39.3%) were the purchasers with the greatest impact on product purchases. Consumer propensity to buy milk was shown in the order of expiration date(4.80 points), and nutrition facts(4.01 points). (4.88 points) and enhanced nutrients(4.59 points) should be promoted for milk consumption. Therefore, it is thought that continuous nutrition education should be made together in order to increase consumption of milk of children and education targeting teachers and school parents should be conducted as well. And in order for children to drink milk without repulsion, the development of various products satisfying both symbolic aspects and nutritional aspects should continue to be made.
