This study examined the changes in the service mix of Korean hospitals in 6 metropolitan cities between 2003 and 2005, and assessed whether the sample hospitals exhibit consistent trend or chance variation in multiple years. Three measures of hospital service mix, focusing on the specialization of services, were applied: information theory index, internal Herfindahl index, and number of distinct diagnosis-related groups (DRGs) treated. National Health Insurance claims were used to calculate the indexes. Specialization indexes were calculated in each year, and then examined to identify the pattern over time. Kappa analysis was applied to assess the agreements of specialization score between two years after hospitals were categorized into 4 groups with quartiles. Kappa score showed that the service mix of hospitals were changed during the study years. Specialization scores were increased given the market structure for three years. Hospitals which showed higher or lower specialization scores than the average of the scores consistently classified into the same group. Specialization indexes showed relatively consistent pattern over 3 years, and such consistencies were evident for hospitals regardless of the specialization status. Policy makers can identify the degree of specialization with the indexes, and it could provide a picture of how hospital services were mixed and changed over time.

The purpose of this study was to investigate the influence of additional marketing mix on overall satisfaction of customers at family restaurants in Seoul and Kyongki-province. In this research frequency analysis, reliability analysis, factor analysis, multiple-regression analysis were employed to analyze the data. Additional marketing mix were divided into 3 factors. Employee(${\beta}=0.352$, t(p)=7.221(0.000) had the most positive impact on overall satisfaction. And physical evidence(0.160, t(p)=3.271(0.001) and process(${\beta}=0.114$, t(p)=2.338(0.020) influenced positively(+) in order. As a result, all factors of additional marketing mix influenced significantly overall satisfaction of customers. These additional marketing mix are regarded as effective marketing tactic to reduce intangibility of food-service business. Therefore restaurant company needs to manage additional marketing mix sufficiently to maintain of customers' satisfaction at family restaurants.

The questionnaires were administered to 333 women shopped in a fashion retail store in Gwang-ju city. Data were analyzed by using exploratory and confirmatory factor analysis, Cronbach' ${\alpha}$, and multi-regression analysis. The results were as follows: 1) The dimension of perceived service quality based on expanded marketing mix were classified as follow: product, price, place, promotion, people, physical evidence, process services. Long-term orientation was categorized into four factors: customer satisfaction, trust, commitment, WOM/repurchase intention. 2) For the effect of the perceived service quality by dimension, product, people, physical evidence, process services have significant effect on long-term orientation, while price, place, promotion services have not significant.

지난 선행연구에서 고객만족이 중요하게 다루어졌던 이유는 고객만족을 통한 재구매 및 충성도 확보가 가능하기 때문이다. 다른 소매점포 유형과 차별화를 시도하는 백화점의 경우에도 고객만족은 고객충성도를 제고하기 위한 필수적인 요소이다. 지난 선행연구들이 백화점의 고객만족을 설명하기 위해 단순히 마케팅믹스 요인에 대해서만 접근했다면, 본 연구는 백화점의 차별적인 서비스 요인이 마케팅 믹스와 더불어 고객만족에 어떤 영향을 미치는지를 살펴보는 것이다. 연구의 결과, 입지(유통)요인과 촉진요인은 고객만족에 통계적으로 유의하게 긍정적인 영향을 미치는 것으로 나타났다. 마케팅 믹스의 나머지 제품과 가격의 경우에는 통계적으로 그 영향의 정도를 확인할 수 없었다. 무엇보다도 본 연구에서 추가적으로 고려했던 서비스 요인은 강력하게 고객만족에 긍정적인 영향을 미치는 것으로 나타났다. 그러므로, 백화점의 경우에는 마케팅 전략을 수립함에 있어 마케팅 믹스뿐만 아니라 다양한 서비스 요인에 대해 고려할 필요가 있다고 말할 수 있다.

Objectives : The purpose of this study was to determine whether the published AMI report card could reduce in-patient mortality, 7-day after discharge mortality, and length of stay (LOS). Methods : Interrupted time-series intervention analysis was used to evaluate the impact of the report card for AMI care quality in November 2005 in terms of risk-adjusted in-patient mortality, risk-adjusted 7-day after discharge mortality, and DRGs case-mix LOS using the claim data of Health Insurance Review and Assessment Service. Results : Public disclosure of AMI care quality decreased risk-adjusted in-patient mortality and DRGs case-mix LOS by 0.00050% per month and 0.042 days per month respectively, however there was no effect on risk-adjusted 7-day after discharge mortality. Patterns of effect of public disclosure on AMI outcomes were a fluctuating pattern on risk-adjusted mortalities and a pulse impact for 1 month on DRGs case-mix LOS. Conclusions : We found the public disclosure of AMI care quality had decreasing effects on risk-adjusted in-patient mortality and DRGs case-mix LOS, but the size of the effect was marginal.

Purpose: This study was done to identify determinants of registered nurse (RN) skill mix and staffing level focused on hospital characteristics. Methods: Data were obtained from health insurance claims data and hospital reporting system in the Health Insurance Review and Assessment Service (HIRA) for the year 2010. Data from 2,998 hospitals were analysed using t-test, ANOVA, Pearson correlation, and regression analysis. Results: The RN skill mix and staffing level were positively related to hospital size and the percentage of inpatients to total patients. RN skill mix and staffing level were statistically different across regions. Including nursing aides (NA), however, there was no difference in staffing levels across regions. Medically vulnerable regions, bed operation rate, and the number of patients per doctor were also related to RN skill mix and staffing level. Conclusion: The statically significant determinants of RN skill mix and staffing level included hospital size, region, bed operation rate, percentage of inpatients, doctor-patient ratio. Further study needs to be done to investigate factors including RN supply and wages.

The telecommunications market is expanding rapidly and becoming more substitutive. In this environment, demand forecasting is very difficult, yet important for both practitioners and researchers. in this paper, we adopt the modeling approach proposed dy Jun and Park ［6］. The basic premise is that demand patterns result from choice behavior, where customers choose a product to maximize their utility. We apply a choice-based substitutive diffusion model to the Korean mobile telecommunication service market where digital service has completely replaced analog service. In comparison with Bass-type multigeneration models. our model provides superior fitting and forecasting performance. The choice-based model is useful in that it enables the description of such complicated environments and provides the flexibility to include marketing mix variables such as price and advertising in the regression analysis.

In this paper, we introduce a mathematical model to analyze pricing/quality and service mix strategies for Internet Portal site. This model includes utilities and costs of each participants, i.e., user, third party provider, and portal sites. Especially, we consider portal sites that initiate their businesses by providing free services like free e-mail service or search service and providing several charged services. As the results, we can find that Portal sites should make the target of customers and focus them to maximize their profit. Portal sites should pay their marketing effort not for all customers but pertinent portions of customers. And Portal sites should make more efforts to efficiently develop and provision their services.

The service life of agricultural concrete structures is designed in about 30 to 100 years, but actual service lift is estimated in an average 18 years. Therefore, as the service life of the agricultural concrete structures increases, necessity of repair by aging from various environment condition exposure increases. This study was to determinate the optimum mix proportion of latex modified repair mortar and to improve the durability performance of agricultural concrete structures. The physical and mechanical tests of latex modified repair mortar were performed. Tests of flow, compressive strength, flexural strength and bond strength tests were conducted. Test results show that the optimum nex proportion of latex modified repair mortar, when used in 5% latex volume fraction (weight of cement), 1.5% antifoaming agent (weight of latex), 0.2% PVA fiber volume fraction, 1:2 (binder-sand ratio), 10% silica fume replacement ratio (weight of cement), could result in best performance for the repair of agricultural concrete structures.
