The purpose of this study is to consider activation methods of traditional markets in Jinju city through questionnaire and field survey. Research framework is summarized into two categories: physical environment and operation program. The results are as follows: 1) the gross profit on sales has been decreased continuously and the main causes of that have been recognized as insufficiency of parking lots and convenient facilities and deterioration of environment in spite of facilities modernization project; 2) consumers visited a traditional market because of proper price and reliance on goods, etc. However, they were not satisfied with the physical environment such as parking lots and resting spaces and the operation program such as cultural event and performance. In conclusion it was thought that activation methods of traditional market would be related to the improvement plan in the physical aspect such as parking lots, walkway, convenient and crime prevention facilities and in the operation program aspect such as cultural event, marketing, management consulting, information infrastructure, and delivery system.

We study the effects of the cluster environment on galactic morphology by defining a dimensionless angular momentum parameter ld, to obtain a quantitative and objective measure of galaxy type. The use of this physical parameter allows us to take the study of morphological transformations in clusters beyond the measurements of merely qualitative parameters, e.g. S/E ratios, to a more physical footing. To this end, we employ an extensive SDSS sample, with galaxies associated with Abell galaxy clusters. The sample contains 93 relaxed Abell clusters and over 34,000 individual galaxies. We find that the median ld value tends to decrease as we approach the cluster center, with different dependences according to the mass of the galaxies and the hosting cluster; low and intermediate mass galaxies showing a strong dependence, while massive galaxies seems to show, at all radii, low ld values. By analysing trends in ld as functions of the nearest galactic neighbour environment, clustercentric radius and velocity dispersion of clusters, we can identify clearly the leading physical processes at work. We find that in massive clusters (s > 700 km/s), the interaction with the cluster central region dominates, whilst in smaller clusters galaxy-galaxy interactions are chiefly responsible for driving galactic morphological transformations.

To make provision for the super-aged society, the senior welfare facility which is a kind of typical physical environment of the nursing service would be expected to perform a very important role in local community. This study was conducted to identify the constructs of the servicescapes of senior welfare facility and to draw analysis indicators of it. For this, we performed literature review based on domestic & foreign government guide, service marketing theory and interior architectural results concerning the physical environment of the senior welfare facility. The result of this study showed as follows: servicescapes of the senior welfare facility could be explained as "a whole set of physical environment to support a variety of services provided by the senior welfare facility for the elderly or services of the kind of tangible clues". Analysis indicators of the senior welfare facility's servicescape could be explained as five factors: safety factor, functional factor, aesthetic factor, ambient factor and social factor. In addition we developed 37 pieces of detailed factors referred to five factors. The evaluation and verification of analysis indicators was carried out through 8 experts in-depth interviews. We inspected importance factor using a 5-point Likert scale, therefore safety factor was 4.41, functional factor was 4.27, aesthetic factor was 3.66, ambient factor was 4.20 and social factor was 4.25. More than anything else, in this study, there is a sense that it has established the concept of servicescape adapted to the senior welfare facility and contained a social element between the employees and the physical environment. Theoretical and practical implications of findings are discussed, and future research directions are proposed. we expect to be a little or benefits to the senior welfare facility corresponding to the future of the super-aged society.

사이버 물리 시스템(CPS: Cyber-Physical System)은 물리시스템과 사이버시스템이 통합되어 운영되는 시스템을 말한다. CPS는 대상 물리시스템을 안정적으로 운영하기 위해 다수의 센서를 이용하여 끊임없이 물리 대상을 모니터링하고 현재 상태에 따라 액추에이터 제어를 수행한다. 만약 악의적인 공격자가 자신들의 공격을 은닉하기 위해서 센서들의 측정값을 대상으로 위변조 공격을 수행한다면, 수집된 데이터에 기반하여 운영되는 사이버시스템은 현재 물리시스템의 운영 현황을 확인할 수 없게 된다. 이는 자동화 시스템 및 운전원의 대응을 지연시켜 더욱 큰 피해가 발생하게 된다. 점차 정교해지는 타겟형 공격들로부터 CPS를 안전하게 보호하기 위해서는 센서 및 측정값을 대상으로 수행되는 은닉형 공격을 탐지할 수 있는 대응기술을 개발해야 한다. 그러나 다양한 이기종 장치들이 존재하는 CPS에서 실제 현장장치들을 대상으로 취약점을 분석하고 실증하는 과정은 많은 시간을 필요로 한다. 따라서 본 연구에서는 CPS 은닉형 공격 탐지 기술의 성능 검증에 활용 가능한 중간자 PLC 실험환경 구축 방안을 제안하고 그 실험결과를 제시한다.

The main objectives of this study are to compare the regional differences and to analyse the affecting factors of customer satisfaction. The subjects are 9 hospitals(5 Daegu region, 4 Seoul region) patient satisfaction index that were surveyed the 2004 Hospital Accreditation Program performed by KHIDI(Korea Health Industry Development Institute) and MOHW(Ministry of Health and Welfare). The sample used in this study consisted of 450 inpatients and 454 outpatients. The survey instrument is composed of physical environment items, physician factors, nursing staff factors, ancillary staff factors, administrative procedure items, and quality of hospital stay items. And overall satisfaction, intent to revisit, and intent to recommend as dependent variables are measured. Basically, the reliability and validity of survey items was evaluated. And the T-test was performed to compare regional differences of customer satisfaction. Finally to analyse the affecting factors on overall satisfaction, and customer loyalty(intent to revisit and intent to recommend), the multiple regression analysis was used. This study shows firstly, the Daegu region's patient satisfaction level of inpatients and outpatients is lower than Seoul region. Especially, nursing staff factors and quality of hospital stay items are very low on inpatient's satisfaction. Also all independent variables except the sufficiency of goods in hospital stand are very low on outpatient's satisfaction. Secondly, as a result of multiple regression analysis, ancillary staff factors(Beta=0.281) have a significant effect on overall satisfaction of inpatient cases in Daegu region. In regard to intent to revisit and intent to recommend, physical environment factors have a significant effect. Thirdly, in Seoul region, physical environment factors(Beta=0.430) have a significant effect on overall satisfaction of inpatient cases. In regard to intent to revisit and intent to recommend, administrative procedure items and nursing staff factors have a significant effect, respectively. In conclusion, these results indicate that hospitals in Daegu region make an effort to improve the customer satisfaction level, especially, of physical environment factors on inpatients and administrative procedure factors on outpatients

In case of executing surveys in marine ecosystems, the most important things are scientific selection measures of survey stations that can represent various ecosystems characteristics in subjected areas. The situations show a lot of differences that understand characteristics of marine ecosystems in targeted areas according to selection methods and positions in survey stations. Investigation ranges and station numbers in marine ecosystems are classified according to project characteristics and scales. But, currently a clear divisions or objective standards are not. Therefore, this study tried to provide selection measures of survey station in scientific and objective marine ecosystems through precise analysis among environmental impact statements of coastal development projects until now. In this study, impact scopes of marine ecosystems correspond to physical impact predictions by undertaking projects. Impact ranges were divided into three(physical impact ranges) coastal waters. In case of proposing numbers of survey stations according to this survey ranges, numbers of investigation stations due to minimum survey scopes in targeted projects applied 20~30% of all numbers in survey stations. Number of survey stations due to average investigation scopes within physical impact ranges applied 60~70% of all numbers in investigation stations. Numbers of survey stations due to maximum survey ranges within physical impact scopes applied 10~20% of all numbers in survey stations. So, improvement measures were deducted. Finally, according to prediction ranges in impact of various coastal development projects, several kinds of conclusions are suggested. And, it is thought to be able to use as fundamental database to select investigation stations in marine organisms through this study.
