The purpose of the study were to: (1) determine important home management concepts in the secondary home economics education curriculum, (2) identify the educational needs related to home management perceived by students, home economics teachers, and university professors, (3) identify the factor structure of the home management concepts, (4) use the findings to make recommendations for defining the area of home management in the secondary home economics curriculum. Three versions of the questionnaire were used to assess the needs. One questionnaire was for students, one for home economics teachers, and one for professors. A total of 1,029 students, 385 home economics teachers, and 45 professors responded to the questionnaires. the data were analyzed by using the descriptive statistics, one way ANOVA with scheff -test, and factor analysis. Forty home management concepts were selected based on the related literatures. The respondants perceived these important for the secondary home economics curriculum. However, 36 home management concepts had differences in perceived importance among students, teachers, and professors. Nine factors emerged from the factor analysis. The three factors that were judged of most importance by students were communication and stress management, making money and helping household tasks, and leisure time activities. The professors and teachers perceived decision making and management process and knowing and utilizing resources most important.

Recently, business environments have been changing quickly. To establish competitive advantage, most enterprises have been using information systems such as Enterprise Resource Planning (ERP), Supply Chain Management (SCM) and Customer Relationship Management (CRM). Many consider Business Process Management (BPM) a new innovative solution for enterprise-wide processes. As the BPM system is used more widely and matures, new techniques and functions will be developed by commercial vendors. However, they mainly focus on correctly executing process models, and user convenience has not been considered. In this paper, we have developed a new method of designing business processes, which provides users with an easy modeling interface. The method is based on version management. Version management of a process enables a history of the process model to be recorded. In order to prevent wasted storage, not all of the process versions are stored. An initial version and changes to each process are stored by automatically detecting changes. Our method enhances the convenience of the modeling business processes and thus helps the process designer. A prototype system is presented to verify the effectiveness of our method.

Traditionally. theses and dissertations have been extremely underutilized information sources due to their lack of physical availability. The development of electronic theses and dissertations system will provide the opportunity for theses and dissertations to be recognized as a basic channel for the dissemination of research findings and an essential resource in the discovery process. In digital environment. many universities and libraries throughout the world are now making digitized versions of traditional(print) dissertations available online. The purpose of this paper is to analyze the current theses and dissertations management system based on web questionaries and survey of home pages. and to suggest a standardized theses and dissertation management model in Korea.

First introduced in 1962, LED(light-emitting diodes) emitted low-intensity red light, but modern versions are now available across the ultraviolet, visible, and infrared spectrum, many with very high luminance or brightness. As a result, growing importance of potential safety harzards for human. Now when certificated of CE provide that testing through IEC/EN 62471 for any lamp. Korea standard adopted as it IEC 62471:2006, Photobiological safety of lamps and lamp systems without change, but effectiveness is incomplete. In this paper, we introduce analysis and direction that urgently come into effectiveness of KS C IEC 62471 as a national standard specifications.

Recently, CMM have been recognized as a critical factor to validate the competitiveness of software organizations, even if the organizations have already achieved the ISO9001 certification. Furthermore, the new version of ISO9001:2000 is being required instead of ISO9001:1994. Both CMM and ISO9001 have a common point that they pursuit quality improvement for the organizations processes and products. Therefore, it is important to understand the similarities of specific requirements between the two models in software organizations which attempt to employ both of the models. From this background, this paper compares CMM and ISO9001 by considering the versions in 1994 and 2000 of ISO9001. The results of this research are likely to help software organizations ma]fe a decision for a strategy to adopt CMM and ISO9001.

We consider (worst-case) robust optimization versions of the Economic Order Quantity (EOQ) model with decreasing cost functions. Two variants of the EOQ model are discussed, in which the purchasing costs are decreasing power functions in either the order quantity or demand rate. We develop the corresponding worst-case robust optimization models of the two variants, where the parameters in the purchasing cost function of each model are uncertain but known to lie in an ellipsoid. For the robust EOQ model with the purchasing cost being a decreasing function of the demand rate, we derive the analytical optimal solution. For the robust EOQ model with the purchasing cost being a decreasing function of the order quantity, we prove that it is a convex optimization problem, and thus lends itself to efficient numerical algorithms.

This study suggests a data driven optimization approach, which simulates the models of human learning processes from cognitive sciences. It shows how the human learning processes can be simulated and applied to solving combinatorial optimization problems. The main advantage of using this method is in applying it into problems, which are very difficult to simulate. 'Undecidable' problems are considered as best possible application areas for this suggested approach. The concept of an 'undecidable' problem is redefined. The learning models in human learning and decision-making related to combinatorial optimization in cognitive and neural sciences are designed, simulated, and implemented to solve an optimization problem. We call this approach 'SLO : simulated learning for optimization.' Two different versions of SLO have been designed: SLO with position & link matrix, and SLO with decomposition algorithm. The methods are tested for traveling salespersons problems to show how these approaches derive new solution empirically. The tests show that simulated learning for optimization produces new solutions with better performance empirically. Its performance, compared to other hill-climbing type methods, is relatively good.

A model for expressing meta data syntax in the eXtensible Markup Language(XML) was developed to increase the portability of the Arden Syntax in medical treatment. In this model that is Arden syntax uses two syntax checking mechanisms, first an XML validation process, and second, a syntax check using an XSL style sheet. Two hundred seventy-seven examples of MLMs were transformed into MLMs in ArdenML and validated against the schema and style sheet. Both the original MLMs and reverse-parsed MLMs in ArdenML were checked using a Arden Syntax checker. The textual versions of MLMs were successfully transformed into XML documents using the model, and the reverse-parse yielded the original text version of MLMs.

The purpose of this study is to compare the health service utilization patterns between up and myun and to find the determinants of utilization. For this purpose. this study used different versions of utilization rates. such as crude utilization rates. utilization rates adjusted for population composition. and age-sex adjusted utilization rates. Data used in this analysis were the Community Health Interview Survey which was conducted by interviewing 741 households from August 31 to September 11, 1998 in HongCheon-Gun. KangWon-Do. The major findings of the analysis are summarized as follows: 1. There was a statistically significant difference in the level of health service utilization between up and myun. Depending upon the unit of analysis employed (those who were interviewed vs those who were sick). the difference between up and myun was reversed. 2. Determinants of health service utilization are analyzed using logistic regression. The result showed that predisposing factor influenced health service utilization in rural areas, while the enabling factor didn't.
