This paper is to identifies relationship between service quality, trust toward employees, trust toward store and store loyalty by investigate how service quality influences on trust toward employees and trust toward store, and its, in turn, influence on store loyalty and explain the moderating effect in relationships between service quality and trust toward employees, and service qualty and trust toward store in bank services setting. A survey study was conducted to collect the data with the actual service purchasers at domestic mayor banks. Analysis of structural equation modeling with AMOS 18.0 was performed to test the research hypothesis. The results of the study are as follows: First, it was found to the moderating effect in relationships between empathy dimension of service quality and trust toward employees, and assurance dimension of service quality and trust toward store. Second, service quality shows differential effects on both trust toward employees and trust toward store by dimension but trust toward employees influence on both trust toward store and it, in turn, influence on store loyalty. To sum up, it have to build empathy of service quality for increase of trust toward their customer who have high duration of relationship and have to build assurance of service quality for increase of trust toward store in bank service settings.

The profitability of the dairy and beef industries is largely affected by the actually achieved reproductive efficiency. Although a large proportion of cows worldwide are bred by artificial insemination (AI) services, many potential factors affecting the outcome of pregnancy by AI remain to be addressed. In the present study, we investigated the vaginal microbiota by high-throughput sequencing of 16S rRNA gene and analyzed their association with differential pregnancy outcomes (i.e., pregnant vs. nonpregnant) of multiple AI services in dairy cows. Sequencing of the V3-V4 region totally produced 512,046 high-quality sequences that were computationally clustered into 2,584 operational taxonomic units (OTUs). All OTUs were taxonomically assigned to 10 bacterial phyla. There were statistically significant differences among the three AI service times (T1, T2 and T3) with respect to the Shannon index and number of observed OTUs (p < 0.05). Bray-Curtis distance-based PCoA analysis also revealed that T2 group could be significantly distinguished from T1 and T3. However, no significant difference between the pregnant and nonpregnant cows was found in confidence regarding both alpha diversity and beta diversity. These results could help us better understand the possible influence of vaginal microbial community on pregnancy outcomes of AI service in cows.

Purpose: This research is intended to investigate the EMT students' Knowledge, attitude and behavior and then identify the predictors of the EMT students' attitude. Method: The purpose of study was to examine EMT students' knowledge and attitude toward the elderly using a survey of 286. the instruments in this study were palmore's FAQI(1998) and the 20 item semantic differential scale developed by sanders et al. (1984). Results: The results of this study were as follows : 1. The measuring of respondents' knowledge of the elderly revealed they scored an average of 10.17(${\pm}3.30$) of the full score 25. It also said their success rate to choose the answer on the elderly was 39.59%. 2. Attitudes toward the elderly weren't significantly different EMT students. 3. EMT students educational level and religion were found to impact their attitudes toward the elderly. 4. The feelings from their previous co-living experience with the elderly were significant factors. EMT students attitudes toward the elderly had an significant effect on co-living experience and the feelings in education programs toward the elderly. Conclusion : A well-designed program is essential to change the attitudes toward elderly because The feelings in education programs for the elderly are very important. with more knowledge of the elderly, the attitudes toward the elderly is expected to be more positive. Therefore, it is necessary to improve the enough knowledge of the elderly.

To find out the differences in medical practice according to the environment of patient care and managerial situation of the medical care institutions, normal spontaneous vaginal delivery and acute appendicitis were selected, which is suitable for comparison because of their high comparability. A total of 473 cases of normal spontaneous vaginal delivery and 408 cases of acute appendicitis was sampled from the claims to Korea Medical Insurance Cooperations during January to June 1984. Complicated cases were excluded from population and sampling was restricted from 40 to 60 percentile for total charges by the type of medical care facility in order to rule out the influence originating from case mix. Important items representing type and quantity of medical care service were compared by type of facility. Major findings are as follows : 1. University hospital shows the highest in charges per case and decrease in order of general hospital, and clinic. 2. In case of normal spontaneous vaginal delivery, average length of stay shows statistically significant difference by type of facility. 3. Charge amount for each service item affected by practice pattern shows statistically significant difference mostly by type of facility. It is suggested that medical practice pattern is different by type of facility for medical services. 4. Difference in total medical expenditure by type of facility is affected more with charges for materials, consumables and drugs than with fee for service activity. 5. In administering drugs to patients, hospital and clinic show higher injection rate than university and general hospital. 6. Clinical Laboratory tests were common in order of uninalysis, hemoglobin, hematocrit, white blood cell count, urine microscopic examination in cases of normal spontaneous vaginal delivery; white blood cell count, urinalysis, hemoglobin, hematocrit, urine microscopic examination, white blood cell differential count, in cases of acute appendicitis. 7. The result for Laboratory test and Radiologic study shows extreme difference by type of facility. Test rate is lowest in clinic and increase hospital, general hospital, and university hospital in order, both in type and frequency.

Internet-based shopping business spread rapidly in Korea. Companies are trying to develop and use various strategic competences. The strategies employed by those companies include activities related to the design of shopping site, market positioning, assistance of purchasing process, payment mechanism, and provision of various consumer services. However, the success of these strategies depends on various environmental factors and internal capability of the companies. In this study, I examined four successful Internet shopping mall companies and compared them to draw useful guidelines for Internet-based intermediary business. These four companies were selected because they are all considered successful by now, but brought different background. We found follows. First, each company tried to economize their own historical and developmental background. All of the selected companies were alike in their focus on the whole Internet user group. Customer needs analysis was performed more systematically. The Importance of customer information and the use of it are not sufficient. Second, Each companies consistently emphasized the importance of market-related activities. Despite the differences in initial states, all companies used similar strategies and had similar focus in target market and products. Conclusively, implications from this research for Internet shopping business can be summarized as follows. First, One of the important future directions for Internet shopping mall business is to broaden target market. Second, the provisions of carefully designed customized services are one success factor. Third, As customer traffic increased, the provision of differential customer service becomes a key success factor.

As Internet and World Wide Web become more popular in our society, the interests in effective application to the field of rural development and agricultural extension service are increasing. The potential in Web-based agricultural extension service is expressed in many areas, such as agriculture information, Web-based training and education, and virtual rural community for rural development and agricultural extension service. The research on the Web and its related issues has been conducted in many ways, but the interests in the competencies and skills of staff who are in charge of Web developing and managing have not been exposed yet. The purpose of this study was to investigate the important competencies and skills for Web developing and managing for enhancing the effectiveness of rural development and agricultural extension service. Twelve extension service staff and on staff in the extension service support center were interviewed. The results of study showed that there were eight essential competencies; competencies to understand rural community and agricultural extension service, to understand the farmers as Web users, to design and develop effective Web sites, to understand the nature of hypertext, to utilize instruction theories, to absorb new technology, to manage projects, and to utilize external sources. The results of study also showed that there was lack of support systems for Web development and information. Overall, the findings of this study suggest that establishing long-term education and training system for technology, electronic performance support systems, and cooperation with universities and colleges for technology are of particular importance for promoting Web-based extension services.

Although the universal health insurance, National Health Insurance (NHI), have improved access to health care and financial burden of health care costs for Koreans, limited coverage of the NHI leads to high out-of-pocket payment for health care. This study examines financial burden of household health expenditures by income level. Data from the Urban Household Expenditure Survey from 1985 through 2005 is analyzed and household expenditure is used as a proxy measure for income. Health expenditures include spending for inpatient care, ambulatory care and pharmaceuticals. If a household spends health expenditure above 40% of household consumption except for foods, that is defined as catastrophic health expenditure. Access to health care for the lowest income group had been improved for two decades relative to other income groups as well as in absolute term. However, both financial burden of health expenditures and the proportion of households that experienced catastrophic health expenditure had been increased in the lowest income group. Study findings have several policy implications. First, in terms of financial burden of health expenditures. the differences among income groups decreased until 2000 but it was worsen in 2005. This suggests that recent policies for extending NHI coverage are not enough to improve the disparity by income level. Second, a differential catastrophic coverage by income level would be an effective strategy that relieves financial burden for low income group. Third, since the catastrophic coverage is applied to only covered services by the NHI, additional strategy for uncovered services should be considered.

A finer granular scalable (FGS) version of ISO/IEC MPEG-4 video streaming is investigated in this work with the prioritized stream delivery over loss-rate differentiated networks. Our proposed system is focused on the seamless integration of rate adaptation, prioritized packetization, and simplified differentiation for the MPEG-4 FGS video streaming. The proposed system consists of three key components: 1) rate adaptation with scalable source encoding, 2) content-aware prioritized packetization, and 3) loss-based differential forwarding. More specifically, a constant-quality rate adaptation is first achieved by optimally truncating the over-coded FGS stream based on the embedding rate-distortion (R-D) information (obtained from a piecewise linear R-D model). The rate-controlled video stream is then packetized and prioritized according to the loss impact of each packet. Prioritized packets are transmitted over the underlying network, where packets are subject to differentiated dropping and forwarding. By focusing on the end-to-end quality, we establish an effective working conditions for the proposed video streaming and the superior performance is verified by simulated MPEG-4 FGS video streaming.

Due to the recent changes in the education market and Corona, Consumers have moved to the tutoring and online learning markets, and the large-scale education service franchise business is reorganized into a small-scale franchise, a business model that maximizes the profit structure from a position where sales are important. Recently, a new learning balance model that can provide individualized services from teacher-centered to student-centered, motivate students is required. In this paper, we propose a new mathematical franchise model (K-MODEL) that can improve a company's profit structure while satisfying the recent education trends and consumer needs from the point of view of the franchise. K-MODEL expects franchisor and franchisees to have a stable profit structure by developing differentiated content and services, learning and operating processes, and various programs to improve learning achievement.

Given that the current Idol fandom has been enormously affected by the development of digital technology such as the Internet, mobile or social media, this study explored how generational fandom culture has been shifted depending on the fandom's use of differential online platforms and services, i.e., online community vs. social network services. The survey results indicate that 3^rd generation fandom showed significantly greater intimacy, greater attachment/worship, greater similarity toward Idol stars as well as greater fandom loyalty and greater fandom identity than 1^st and 2^nd generation fandom. Similarly, compared to online community centered fandom, social network centered fandom showed greater intimacy, greater attachment/worship, greater similarity as well as greater fandom loyalty and identity than community-centered fandom.
