  • In the process of die manufacturing, according to increasing demand of die and molds, the efficient machining of dies and molds has been increased. However, while the cutting process has been automated by the progress of CNC(computer numerical control) and CAD/CAM, the polishing process still depends on the experienced knowledge of an expert. Also, even when workers are skilled in polishing dies. it takes much time to obtain the required roughness and smoothness on the surface of a die. Moreover, many workers gradually avoid doing polishing work because of the poor working conditions caused by dust and noise. Therefore, to improve productivity and to solve the potential shortage of skilled workers, a user-friendly automatic polishing system was developed in this research. The developed polishing system with five degrees of freedom is able to keep the polishing tool normal to the die surface during operation and is able to maintain a pressure constantly by the developed pneumatic system. Also, to evaluate polishing performance of the developend system and find the polishing conditions, the various polishing experiments were carried out.

  • This paper analyses the hindrance factors of process capability. The reasons of the products which are out of specification can be accounted on the hindrance factors. An $\hat{e}$nquete which consists of 4 categories such as technical knowledge, work performance, work environment, and human relations at home and office, is prepared and handed out to 1000 works to get information. And Spearman's Correlation Coefficient (${\rho}s$) is adapted as an anaysis and consideration criterion. In consequence, it is revealed the next 4 factors become the vital hindrance factors of process capability: (1) unskillful working (2) over load for operators (3) imperfect work environment (4) incoordination of human relations And the correspondent policy can be summarized as follows: (1) propagation & fixation of I.E. techniques (2) harmonization of human relations (3) improvement of work environment (4) strengthening the T.W.I.

  • In this paper, it is proposed a new approach to the development of the automatic vision system to e famine and repair the steam generator tubes at remote distance. In nuclear power plants, workers are reluctant of works in steam generator because of the high radiation environment and limited working space. It is strongly recommended that the examination and maintenance works be done by an automatic system for the protection of the operator from the radiation exposure. Digital signal processors are used it, implementing real time recognition and examination of steam generator tubes in the proposed vision system. Performance of proposed digital vision system is illustrated by experiment for similar steam generator model.

  • E-business curriculum needs to be developed reflecting requirements of the industry which involve a close relation with a job performed in the field, and a professional knowledge and an expert skill. In this paper, we present a method based on a market-oriented approach for developing an I-business curriculum. For the purpose, we analyze the opinion data resulting from the surveyed opinions of respondents working for I-business companies and evaluate the importance of each course being involved in the curriculum with respect to the job classification (e.g., Web planner, Web master, Web programmer, Web marketer, Web designer, Web PD), and then, complete a flow diagram considering precedence and relative difficulty among the selected courses. The E-business curriculum developed by the proposed method is useful to provide guidelines for determining courses required toward a desired job and for making a partial amendment of the curriculum.

  • This research surveys how much firms are satisfied with the graduates of the MIS Department of C University. The subjects of this research are the graduates of the department who are working as full time workers and their supervisors, coworkers and subordinate workers evaluate how much they are satisfactory regarding their ability and knowledge to do their jobs successfully. The subjects are classified into IS practitioners and non-IS practitioners based on the tasks they are currently taking charge of. The results show that the IT - related part of the curriculum of the department provides a relative advantage for non-IS practitioners and that the management-related part of the curriculum provides a relative advantage for IS practitioners. The results also show that the curriculum does not provide the graduates enough technical proficiency to develop a successful carrier as IS specialists.

  • The interactions between the excavation tool and the excavation environment are dynamic, unstructured and complex. In addition. operating modes of an excavator depend on working conditions, which makes it difficult to derive the exact mathematical model of excavator. Even after the exact mathematical model is established, it is difficult to design of a controller because the system equations are highly nonlinear and the state variable are coupled. The objective of this study is to design a fuzzy logic controller (FLC) which controls the position of excavator's attachment. This approach enables the transfer of human heuristics and expert knowledge to the controller. Expeiments are carried out to check the performance of the FLC.

  • Purpose: This article aimed to identify nurses' experience of practice in nursing homes. Method: Using phenomenological approach for qualitative research, the participants were 8 nurses who were working at nursing homse in C city. The data was analyzed by using phenomenological methodology by Colaizzi. Results: Five theme clusters were derived from the data. They were: burden (independent decision making in clinical situations, tension of as a multifunctional member); lowered self-esteem (exhaustion, relative self-evaluation is low, comparing with others); conflict (negative image of elderly, communication break with elderly family, monitoring of nursing home staff); worth (slight improvement of elderly health state, trust and recognition, intimacy); and self-reflection (need for knowledge extension, effort towards enhancing virtue, perception of importance in their health management). Conclusion: The results showed that nursing home nurses experienced negative aspects of various nursing practice, suggesting the ways to solve their negative experience.

  • Machine learning in an uncertain or unknown environment is of vital interest to those working with intelligent systems. The ability to garner new information, process it, and increase the understanding/ capability of the machine is crucial to the performance of autonomous systems. The field of artificial intelligence provides two major approaches to the problem of knowledge engineering-expert systems and neural networks. Harnessing the power of these two techniques in a hybrid, cooperating system holds great promise.

  • The importance of tourism was recognized through the olympiad of 1988. Especially visual impacts like uniform make it more important to develop proper service system. Thus, the object of this study is to provide a renewal uniform policy of Korean restaurant. Here, the theoretical knowledge is applied into actual conditions, and found many problems as a result. 1. There are no recognition of the importance of uniforms. 2. No effort has been made in creating image suitable for traditional restaurants. 3. There has been no uniqueness and utility. 4. The uniform colors have not been coordinated working environments. 5. There have been some problems concerning uniform managements. These problems led to an idea of making new uniforms, and actual products has been producted as a part of the study. The products have focused an functional utility and tradition of Korean costumes. I hope my endeavor will be helpful for traditional Korean restaurants and developing of uniform design.
