Health care marketing can be defined as a process of developing, promoting and administering health care services for the benefits of hospitals as well as consumers. Researchers have reported that one of the significant attributes in the selection of hospital is a client's perceived image of the hospitals. Especially the image of nursing services was one of the important factors of the hospital image. The main purposes of the study were 1) to define the positioning about 5 hospitals' image of nursing services. 2) to define the effects of image attributes to the iamage of hospital nursing services. Eighteen hundred questionnaires were distributed to the parents of middle schools and high schools in Seoul. Among them, 1340 cases were returned but 849 cases were turned out to be useful data and used in final analysis. In data analysis, $SPSS\;/PC^+$ and PC-MDS programs were used for descriptive statistics, multiple regression, and drawing perceptual maps. The image of hospital nursing services was measured developed by the author through literature review and content validation. Reliability coefficients was found to be statistically appropriate level of confidence(Cronbach's Alpha=.8617). The results were as follows : 3) The perceptual map shows that hospital A, B and C,D,E were divided into five groups(See Fig. 1). That is, hospital A, and B are located in a close position and hopital C & E are located at opposite position between X-axis, Hospital D was located in the middle area of the hospital C and:E. In conclusion, this research visiblely depicted perceptual maps using MDS of the consumer's image about hospital nursing services. Since hopital nursing services were differentiated by the image attributes in consumer's perception, the results of the study can help hospital managers plan marketing strategy according to their strong points or weak points. Because the necessity of marketing in recent health care was importantly recognized, this research which is adopting posititioning concept will contribute to the consumers and hospital organizations.

Recently, the hospitals in Korea has positively changed one way or another. Therefore hospital managers must focus on the nurses' role in terms of consumers' perception of overall image of hospitals and the degree of satisfaction of the consumers. To achieve the purposes, the questionnaire was developed and distributed to 280 people who had a direct experience with nursing services subjected hospitals in Seoul at the time of screening. Among them, 229 responses were turned out to be useful and used for final analysis. The measurement instrument for hospital nursing service quality evaluation was modified from the SERVQUAL model originated from Parasuraman, Zeithaml, and Berry (1988). For data analysis, SPSS/PC and PC-MDS program were used. The results were as follows : 1) The perception map showed that the seven subjected hospitals were divided into three groups. It could be interpreted that the hospitals in the same group had a strong competitive relationships. Because the nursing services' scores of hospitals C and E were higher than those of other hospitals, they could be served as a benchmark for the other hospitals. 2) The marketing place of hospital nursing services was divided by four. Since service generally had a strong point in nearby service market segment. Aiming an nearby hospital nursing services market segment by the hospital nursing services department was regarded as a good repositioning strategy. 3) When consumers evaluated the quality of hospital nursing services, they were greatly affected by the hospitals' overall image or other characteristics. Therefore, for improving hospital's nursing services, hospital nursing services department requires a great deal of labor to improve hospitals' overall image or other characteristics.

최근 MPEG-A(ISO/IEC 23000)에서는 MAF(Multimedia Application File Format)[1]라는 새로운 멀티미디어 파일 포맷을 제안하고 있다. MAF 파일포맷은 기존의 MPEG 압축 규격을 갖는 미디어 파일에 더해, 미디어 내용 정보를 기술하는 메타데이타를 MPEG-7을 사용하여 하나의 시스템 포맷 내에 포함할 수 있도록 해준다. 하지만 현재로서는 이러한 표준을 구현한 실제 시스템이 없기 때문에, 응용 측면에서 MAF가 얼마나 유용한지 검증하기 어렵다는 문제점을 가지고 있다. 본 논문에서는 PC와 모바일 단말기상에서 MPEG-A 표준을 기반으로 한 멀티미디어 검색 시스템을 설계 및 구현한다. 또한 MPEG-A에서는 아직 동영상에 관련된 메타데이타에 대해서는 제안된 바가 없기 때문에 MPEG-7 MDS(Multimedia Description Scheme)[2]와 TV-Anytime[3]을 기반으로 모바일 환경에서도 저작 및 사용하기 편리한 메타데이타들을 설계한다. 전체 시스템을 설계하기 위해서 MAF 검색 시스템이 가져야 할 5가지 요구사항인 이식성, 확장성, 호환성, 적응성, 효율성을 정의하고 이러한 요구사항을 바탕으로 하여 MAF 검색 시스템의 전체 구조를 응용 계층, 미들웨어 계층, 플랫폼 계층으로 설계한다. 제안하는 검색 시스템은 MAF 형식의 멀티미디어 데이타를 저작, 재생, 검색할 수 있는 클라이언트 파트와, 대용량의 MAF 형식의 멀티미디어 파일과 MAF 파일로부터 추출한 MPEG-7 형태의 메타데이타를 저장, 관리할 수 있는 서버 파트로 구성된다. 그리고 설계한 MAF 검색 시스템의 유용성을 검증하기 위하여, PC에서는 MS 윈도우 플랫폼 그리고 모바일 단말기에서는 WIPI 플랫폼 상에서 클라이언트 시스템을 구현하고 시스템 요구사항들을 모두 만족하는지 여부를 확인한다. 제안하는 검색 시스템은 MPEG-A 표준을 검증하고 그 유용성을 확인하기 위해 사용될 수 있다.

As the lifestyle of consumers changes and the need for various products increases, new products are being developed in the market. Each household owns various home appliances which are purchased through the choice of a decision maker. These appliances include not only large-sized products such as TV, refrigerator, and washing machine, but also small-sized products such as microwave oven and air cleaner. There exists latent correlation among possession of home appliances, even though they are purchased independently. The purpose of this research is to analyze the effect of demographic factors on the purchase and possession of each home appliances, and to derive some relationships among various appliances. To achieve this purpose, the present status on the possession of each home appliances are investigated through consumer survey data on the electric and energy product. And a multivariate probit(MVP) model is applied for the empirical analysis. From the estimation results, some appliances show a substitutive or complementary pattern as expected, while others which look apparently unrelated have correlation by co-incidence. This research has several advantages compared to previous literatures on home appliances. First, this research focuses on the various products which are purchased by each household, while previous researches such as Matsukawa and Ito(1998) and Yoon(2007) focus just on a particular product. Second, the methodology of this research can consider a choice process of each product and correlation among products simultaneously. Lastly, this research can analyze not only a substitutive or complementary relationship in the same category, but also the correlation among products in the different categories. As the data on the possession of home appliances in each household has a characteristic of multiple choice, not a single choice, a MVP model are used for the empirical analysis. A MVP model is derived from a random utility model, and has an advantage compared to a multinomial logit model in that correlation among error terms can be derive(Manchanda et al., 1999; Edwards and Allenby, 2003). It is assumed that the error term has a normal distribution with zero mean and variance-covariance matrix ${\Omega}$. Hence, the sign and value of correlation coefficients means the relationship between two alternatives(Manchanda et al., 1999). This research uses the data of 'TEMEP Household ICT/Energy Survey (THIES) 2008' which is conducted by Technology Management, Economics and Policy Program in Seoul National University. The empirical analysis of this research is accomplished in two steps. First, a MVP model with demographic variables is estimated to analyze the effect of the characteristics of household on the purchase of each home appliances. In this research, some variables such as education level, region, size of family, average income, type of house are considered. Second, a MVP model excluding demographic variables is estimated to analyze the correlation among each home appliances. According to the estimation results of variance-covariance matrix, each households tend to own some appliances such as washing machine-refrigerator-cleaner-microwave oven, and air conditioner-dish washer-washing machine and so on. On the other hand, several products such as analog braun tube TV-digital braun tube TV and desktop PC-portable PC show a substitutive pattern. Lastly, the correlation map of home appliances are derived using multi-dimensional scaling(MDS) method based on the result of variance-covariance matrix. This research can provide significant implications for the firm's marketing strategies such as bundling, pricing, display and so on. In addition, this research can provide significant information for the development of convergence products and related technologies. A convergence product can decrease its market uncertainty, if two products which consumers tend to purchase together are integrated into it. The results of this research are more meaningful because it is based on the possession status of each household through the survey data.
