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.

Objectives : An appropriate sampling strategy for estimating an epidemiologic volume of diabetes has been evaluated through a simulation. Methods : We analyzed about 250 million medical insurance claims data submitted to the Health Insurance Review & Assessment Service with diabetes as principal or subsequent diagnoses, more than or equal to once per year, in 2003. The database was re-constructed to a 'patient-hospital profile' that had 3,676,164 cases, and then to a 'patient profile' that consisted of 2,412,082 observations. The patient profile data was then used to test the validity of a proposed sampling frame and methods of sampling to develop diabetic-related epidemiologic indices. Results : Simulation study showed that a use of a stratified two-stage cluster sampling design with a total sample size of 4,000 will provide an estimate of 57.04%(95% prediction range, 49.83 - 64.24%) for a treatment prescription rate of diabetes. The proposed sampling design consists, at first, stratifying the area of the nation into "metropolitan/city/county" and the types of hospital into "tertiary/secondary/primary/clinic" with a proportion of 5:10:10:75. Hospitals were then randomly selected within the strata as a primary sampling unit, followed by a random selection of patients within the hospitals as a secondly sampling unit. The difference between the estimate and the parameter value was projected to be less than 0.3%. Conclusions : The sampling scheme proposed will be applied to a subsequent nationwide field survey not only for estimating the epidemiologic volume of diabetes but also for assessing the present status of nationwide diabetes control.

Animal disease surveillance system, defined as the continuous investigation of a given population to detect the occurrence of disease or infection for control purposes, has been key roles to assess the health status of an animal population and, more recently, in international trade of animal and animal products with regard to risk assessment. Especially, for a system aiming to determine whether or not a disease is present in a population sensitivity of the system should be maintained high enough not to miss an infected animal. Therefore, when planning the implementation of surveillance system a number of factors that affecting surveillance sensitivity should be taken into account. Of these parameters sample size is of important, and different approaches are used to calculate sample size, usually depending on the objective of surveillance systems. The purpose of this study was to evaluate the sensitivity of the current national serological surveillance programs for four selected bovine diseases assuming a specified sampling plan, to examine factors affecting the probability of detection, and to provide sample sizes required for achieving surveillance goal of detecting at least an infection in a given population. Our results showed that, for example, detecting low level of prevalence (0.2% for bovine tuberculosis) requires selection of all animals per typical Korean cattle farm (n = 17), and thus risk-based target surveillance for high risk groups can be an alternative strategy to increase sensitivity while not increasing overall sampling efforts. The minimum sample size required for detecting at least one positive animal was sharply increased as the disease prevalence is low. More importantly, high reliability of prevalence estimation was expected with increased sampling fraction even when zero-infected animal was identified. The effect of sample size is also discussed in terms of the maximum prevalence when zero-infected animals were identified and on the probability of failure to detect an infection. We suggest that for many serological surveillance systems, diagnostic performance of the testing method, sample size, prevalence, population size, and statistical confidence need to be considered to correctly interpret results of the system.
