Purpose - This study aims to identify the priorities of medical service quality improvement by customer satisfaction characteristics and potential customer satisfaction improvement (PCSI) index based on the dualistic quality classification of Kano Model (1984) for Comprehensive Health Screeening Center in General Hospitals and Centers only for Comprehensive Health Screening and suggest a direction for future improvement. Research design, data, and methodology - Through advanced research on health screening medical service quality, this study set four service quality factors, including tangible, human, process and supportive factors, and 39 measurement items. Based on these items, the study used 117 questions, which consist of dualistic quality factors, customer satisfaction coefficients, positive and negative questions for PCSI index and questions for current satisfaction. 300 effective samples were collected for adults in their 20s who experienced health screening service in Seoul, Gyeonggi-do and Incheon within the past two years. Collected data were input in the quality evaluation duality table to categorize quality factors and calculate customer satisfaction coefficients by Timko(1993). The study also analyzed PCSI index in comparison with current satisfaction and identified priorities in quality improvement. Results - It was found that the most urgent factors to improve the quality in both groups were adequate waiting hours and emergency response for complications, which are process factors classified as unitary quality. It is urgently needed to improve the quality as the PCSI index was high in supportive factors (complaint response team) as attractive quality in Comprehensive Health Screening Center in General Hospitals and in process factors (prevention of infection) as unitary quality in Centers only for Comprehensive Health Screening. As the PCSI index was low in space use as a tangible factor, it was found that the current level can be maintained instead of improvement. Conclusions - To improve the health screening medical service quality, it is required to focus on process factors (adequate waiting hours, emergency response for complications, prevention of infection) and supportive factors (complaint response team) among service qualities perceived by users. It is proposed to ensure continuous efforts to manage and reinforce priorities as a direction for future improvement in health screening service.

Recently, the material industry in the world has started appreciating the value of new materials that can overcome the limitation of steel material. In particular, new materials are expected to play a very important role in the future industry, demonstrating superior performance compared to steel in lightweight materials and ability to maintain in high temperature environments. Carbon materials have recently increased in value due to excellent physical properties such as high strength and ultra lightweight compared to steel. However, they have not overcome the limitation of productivity and price. The carbon materials are classified into various composites depending on the purpose of use and the performance required. Typical composites include carbon-glass, carbon-carbon, and carbon-plastic composites. Among them, carbon-carbon composite technology is a necessary technology in aviation and space, and can be manufactured with high investment cost and technology. In this paper, in order to find the optimal conditions to achieve productivity improvement and cost reduction of carbon material densification process, the correlation between each process parameters and results of densification is first analyzed. The main process parameters of the densification process are selected by analyzing the correlation results. And then a certain linear relationship between major process variables and density of carbon materials is derived by performing a regression analysis based on the historical production result data. Using the derived casualty, the optimal management range of major process variables is suggested. Effective process operation through optimal management of variables will have a great effect on productivity improvement and manufacturing cost reduction by shortening the lead time.

This study conducted parking demand-supply analysis of 13 big discount stores' in Busan using qualitative and quantitative methodologies. Based on the analysis, we reexamined the parking requirements in discount stores and suggested effective use plan of established parking lots. We found that all big discount stores in the study had more parking spaces than actual parking demands. Also, there are differences of parking occupancy rate by their location types. Third, even if the minimum standard for parking provision in the stores is reduced by up to 20%, they would be adequate to respond current parking demands. Thus, we suggest to consider different parking standards depending on location types. Finally, in order to utilize surplus parking spaces, this study suggests to examine whether parking with various purposes besides shopping is permitted or not.

The purpose of this study was to identify the important contents from teachers’, parents’and students’view points based on the sixth Home Economics textbook contents, to apply these results at school settings and to provide the materials as a basis for the next curriculum revision. Subjects were 59 teachers, 253 parents, and 389 students from 3 cities and 5 counties in CholaBukDo. A questionnaire which was made by the researcher was used as an instrument for this study. The results are as follows： Of 32 contents on Family life subarea, all the teachers, the parents and the students put the emphasis on sex such as pregnancy, purity, sex-ethics, etc. This result means that middle-school students emphasized the sexual identity formation and this was also a common concern about adolescents in our society. Of 37 contents of Managing home resource and Consumer life subarea, teachers though the environment pollution is an important subject and parents and students thought finding a method to conserve good environment were more important. This result reflects their concern on the environment. Of 49 contents on Dietary life, teachers and parents emphasized “the importance of nutritive elements”which is basic on their dietary life and students were more interested in “adolescence and growth and development among adolescents’nutritional characteristics and problems”which is more related to their current life. Of 40 contents on Clothing life subarea, while teachers put the emphasis on the method how they can buy ready-made clothes, parents and students wanted them to teach what kind of clothes are suitable for themselves. Of 18 contents on Residing life subarea, teachers emphasized the importance of ventilation for adjusting the room environment and students were more interested in the effective use of the residing space. By finding out what kinds of Home-economics contents are important from the view point of teachers, parents and students, this study can be a useful resource for the next curriculum revision and for selecting contents of a new-coming text book. However, restricted sampling must be considered and further studies which cover the whole area might be needed.

Recently, there has been an increased interest in the noise isolation capacity of floor slabs, and thus an increase of slab thickness is required. In addition, long span floor systems are frequently used for efficient space use of building structures. In order to satisfy these requirements, a biaxial hollow slab system has been developed. To verify the structural capacity of a biaxial hollow slab system, safety verification against earthquake loads is essential. Therefore, the seismic behavior of a biaxial hollow slab system has been investigated using material nonlinear time history analyses. For efficient time history analyses, the equivalent plate element model previously proposed was used and the seismic capacity of the example structure having a biaxial hollow slab system has been evaluated using the nonlinear finite element model developed by the equivalent frame method. Based on analytical results, it has been shown that the seismic capacity of a biaxial hollow slab system is not worse than that of a flat plate slab system with the same thickness.

Most threats of WLAN are easily caused by attackers who access to the radio link between STA and AP, which involves some Problems to intercept network communications or inject additional messages into them. In comparison with wired LAN, severity of wireless LAN against threats is bigger than the other networks. To make up for the vulnerability of wireless LAN, it needs to use the Intrusion Detection System using a powerful intrusion detection method as SVM. However, due to classification based on calculating values after having expressed input data in vector space by SVM, continuous data type can not be used as any input data. In this paper, therefore, we design the IDS system for WLAN by tuning with SVM and data-mining mechanism to defend the vulnerability on certain WLAN and then we demonstrate the superiority of our method.
