In order to provide economic high-quality products to customers in a timely manner, companies have tried much effort to decrease the time period of engineering design and information management. As a part of this effort, we have developed the Drawing Information Management System(DIMS) based ofn GT(Group Technology) that could decrease design processing time by speedy and rational management of design processes. The characteristics of DIMS are as follows: First, the concept of Concurrent Engineering was applied to DIMS. Through LAN, reviewers are able to attach comments to dlectronic documents by anno- tation functions called Mark-up. The reviewer annotations are collected and combind with the original document to revise the documents. Second, we have developed a Classification and Coding(C&C) system suitable for electronic component parts bassed on GT(Group Technology). The C&C system makes both parts and drawing with similar characteriscs into families and helps users search existing documents or create new drawings promptly. Finally, DIMS provides the Engineering BOM(Bill of Material) using the concept of Family BOM based on model options.

We in this paper proposed a distinction method to compare objects in the Korean medicine ontology. Comparing same and different information between two objects, two scenarios to use our system were designed and implemented. One is the distinction of formulas, medicinal materials, and acupuncture points and the other is the distinction of effects, treatments, and symptoms. To compare objects easily, the decomposition of effects and treatments and the processing of medicinal materials were provided. Also, information of each object was shown through the link to the semantic search system. Our distinction method and system could be helpful to compare and distinct two objects in the diagnosis systems or search systems of Korean medicine information.

Environmental matters have more influence on business performances. Consequently, as a way to cope with environmental matters, much more interests in environment-friendly management have increased recently. First-rated hotels and food-service restaurants have been concentrating on gaining ISO 14001 EMS(Environment Management System), which is regarded as objective and international, to solve and prevent environmental matters. However, there are some internal and external problems emerged in the food-service industry and first-rated hotels. Therfore, covering the examples of ESH(Environment Safety Health) management which was developed by H group and based on ISO 14001 EMS, this study aims to observe merits of ISO 14001 EMS as a model that can develop an environment management system, and to consider an improvement plan for better understanding of licensed cooks in restaurants.

K-means is a popular and efficient data clustering method that only uses intra-cluster distance to establish a valid index with a previously fixed number of clusters. K-means is useless without a suitable number of clusters for unsupervised data. This paper aimsto propose the Group Search Optimization (GSO) using Silhouette to find the optimal data clustering solution with a number of clusters for unsupervised data. Silhouette can be used as valid index to decide the number of clusters and optimal solution by simultaneously considering intra- and inter-cluster distances. The performance of GSO using Silhouette is validated through several experiment and analysis of data sets.

The computerization works and environment have been changed from simple transaction and data process request to system connection request, from data computerization to application work automation and process computerization through IT development and Internet spread. Recently, BPM(Business Process Management) concept has been widely propagated. It is expanding interest of business subject. Korea Railroad is operating train operation management system through 5 regional headquarters and organizations under the influence of each regional headquarter. But integrated operation and management of communication each department, work flow management and resources of depot equipment and materials have to need a lot of effort and time in huge organization as Korea Railroad. Therefore, this article realized Web Based BPM Group Ware. This article will define Korea Railroad organization and business process in using this Group Ware. And it will introduce Korea Railroad computer manage system of this Group Ware and efficient Korea Railroad Business Process through modeling and operating department work and resources management in Korea Railroad.

To enhance the administrational efficiency and for university facility and space management to be public, this research suggests a competent and an objective evaluation system and index. The study will assist national and university finances to contribute towards advanced education. Furthermore, figure out the space management condition of national university by utilizing the evaluation system, and through that suggesting efficient special management method. According to the result of this study, evaluation system for university facility can be widely divided into seven categories; system preparation, members conference, propriety of space allocation, propriety of management system, space use ratio, time control of space use, imposition index of surplus use. Based on these subdivisions, the space management category contains 19 evaluation items and the marking system allows perfect score of 100 points. In result of examining space management condition using the evaluation system, space management was well enforced in research focused university group where as in education centered university group, it shows relatively low enforcement. It also illustrated that efforts of evaluation items were required in categories of imposition index of surplus use and special use ratio in order for efficient space management.

This is a study on types of foodservice system, the menu, role of the Dietitian, management of the facilities and utensil through the survey conducted at 105 enterprises located in Seoul industrial foodservices which were evenly divided into three groups ; large size of feeding group, medium size of feeding group, small size of feeding group. The sresults are below, 1. Most institutional foodservice was enterprise under direct management. 2. Selective menu was set for the large size of feeding group than small size of feeding group. At budget making, personal management and purchansing management, the dietition role was not important in the large size of feeding group than in the small size of feeding group. 3. Equipped rate of facilities and utensil were greater volume for the large size of feeding group.

The purpose of this study is to analyze the impact of quality management system requirements, a management innovation technique, on business performance to secure the competitiveness of SMEs in an environment of increasing uncertainty in the global economy and intensifying competition. To this end, a survey was conducted on small and medium-sized enterprises (SMEs) operating a quality management system, and statistical analysis was performed through validity and reliability analysis, regression analysis, and group analysis using IBM SPSS 26.0. As a result of the study, it was found that planning, operation, support, and improvement, which are the core requirements of a quality management system, have a positive effect on business performance. In addition, through group analysis, it was found that the effect of quality management system requirements on business performance varies according to the level of the company. This means that the importance of quality management requirements required for strategy establishment varies according to the quality management introduction level of small and medium-sized manufacturers, and it can be used for small and medium-sized manufacturers to set strategic directions.
