The amount of information on the Web is explosively growing as the Internet gains in popularity. However, only a small portion of the information on the Web is truly relevant or useful to the user. Thus, offering suitable information according to user demand is an important subject in information retrieval. In e-commerce, the recommender system is essential to revitalize commercial transactions, raise user satisfaction and loyalty towards the information provider. The existing recommender systems are mostly based on user data collected at servers, so user data are dispersed over several servers. Therefore, web servers that lack sufficient user behavior data cannot easily infer user preferences. Also, if the user visits the server infrequently, it may be hard to reflect the dynamically changing user's interest. This paper proposes a novel personalization system analyzing the user preference based on web documents that are accessed by the user on a user device. The system also identifies non-content blocks appearing repeatedly in the dynamically generated web documents, and adds weight to the keywords extracted from the hyperlink sentence selected by the user. Therefore, the system establishes at an early stage recommendation strategies for the web server that has little user data. Also, user profiles are generated rapidly and more accurately by identifying the information blocks. In order to evaluate the proposed system, this study collected web data and purchase history from users who have current purchase activity. Then, we computed the similarity between purchase data and the user profile. We confirm the accuracy of the generated user profile since the web page containing the purchased item has higher correlation than other item pages.

Traditionally, the emphasis of the information services had been placed on the information provider's knowledge of information sources or information systems. However, in view of the increasing complexity of the information environment. and changes taking place in information professions the evaluation of the information services has callded for further research in interpersonal communication aspects of the librarian user interface especially that which links to user satisfaction. This experimental study was carried out for the purpose of exploring the implications of nonverbal behaviors in measuring user satisfaction in the light of the fact that the meaning of nonverbal clues includes more than verbal communication especially in dealing with variable barriers even though they operate at low levels of awareness. In this sense, among the wide range of nonverbal communication areas in particular kinesics, artifacts and the proximics were examined to suggest alternative model which can be applied effectively in our specific set of information work environment. Two major university libraries and two research libraries in Korea were chosen and visited for the anlysis and per each refernce/information interview the librarian's nonverbal behaviors were checked on the observer's checklist and the qustionnaires completed by the user at a time. On the basis of these data firstly, the relation of user satisfaction concerned with the librarian's nonverbal communication to user satisfaction with information services was analyzed and the possible communication barriers were investigated. In addition, the effect of training the information librarian with positive nonverbal communication skills on the user's satisfaction was analyzed in a SAS computer program in the area of kinesics. On the other hand, the effect of other nonverbal behaviors such as proximics and artifacts known very important clues to improving a complex human interaction was discussed along with their experimental results. In conclusion, it was found that most of users were not sensitive to the importance of nonverbal behaviors exposed by the information librarian, but it was proved that the ultimate user satisfaction and the satisfaction of the librarian's nonverbal behaviors are correlated positively, Moreover, nonverbal behaviors displayed by the trained librarian toward the user had a considerable effect on the user's evalution of information services compared with those by the untrained. These findings imply that in order to control the librarian's nonverbal behaviors and to help the user overcome his barriers the information librarian as a specialist needs to assure and modify willilingly his communication behavior. Without making effective use of such nonverbal communication, information librarian could not expect to meet the user's information needs either. However, when these positive nonverbal behaviors are applied it would be highly desirable to be aware of cultural and contextual differences. With regard to increasing information services success the applicable nonverbal communication model for library management and education can be suggested as below.

research tries to present the role of perceived justice and authenticity in service recovery process. Prior research on the service recovery have focused on relationship among perceived justice, recovery satisfaction and positive customer behavior. Especially perceived justice including distributive, procedural, and interactional justice has addressed as most important antecedents of recovery satisfaction. Although the pivotal role of perceived justice for successful service recovery has agreed by many researchers, relatively little attention has been paid to emotional aspect of customer. During the service recovery process, even if customer perceived recovery effort from service provider as justice one, they might feel displeasure or dissatisfaction. It means prior researches have underestimated the importance of emotional aspect while they focus on cognitive aspects. The one research focused on emotional aspects examined effect of authenticity in service context with other related factors. However, solely examined effect of authenticity is not enough to present proper implication effect between justice and authenticity so that it can be understood more clearly. In this study, we examined customer reactions to service failure and recovery process in restaurant service settings. Specifically, we focused on the moderating effect of authenticity on the paths between perceived justice and outcome variables such as forgiveness and recovery satisfaction.

The purposes of this study are, 1) to explore the factors related to the family caregivers' preferences for service utilization both of the community-based welfare and health-care services, and 2) to examine the reasons why not want to use services analyzing a survey data obtained from family caregivers(n=1,000). Anderson and Newman's Behavior model was employed to examine the factors related to the preferences for service utilization. The main results are as follows. 1) Logistic regression analyses demonstrated that predisposing factor(such as age and relations with frail elderly) and enabling factor(such as economic status, secondary caregiver, informal informational support provider, etc) were significant predictor for caregivers' preference for service utilization. Contrary to an expectation, needs factor was negatively related to the preference for service. More specifically, the more they have service needs, the less they show their willingness to use community-based service both in welfare and health-care services except for care education program. 2) Caregiver identified 'family caregiving consciousness'(family should take care of frail elderly, elderly dislike be taken care of) as an important reason not want to use community services next to financial factor. These findings have several implications for policy making especially for 'public long-term care insurance' which was planned to start in 2007.

Customer participation in the service encounter plays an important role in the interaction process. In addition, customer participation is affecting the development of relationships between customer-service provider. Previous researches revealed the role of customer participation through a fragmented and cross-sectional approach, however, given the dynamics of the relationship, it is necessary to identify the role of customer participation from a longitudinal perspective. In addition, it is necessary to determine the cause of the overlap between the antecedent variables and consequent variables. This study aims to identify the relational role of customer participation by clarifying how customer participation affects relationship development from a longitudinal perspective, focusing on trust and commitment variables which are keys to relationship marketing. The related role of customer participation is analyzed through a regression analysis through long-term data. The results of the study showed that commitment(t1) directly had a positive effect on customer participation. However, trust(t1) has been shown to have a direct positive effect on the sub-dimensions of customer participation, such as personal interaction and responsible behavior. Customer participation(t2) affected by this trust(t1) and commitment(t1) again turned out to have a positive effect on trust(t3) and commitment(t3). In conclusion, although customer participation is affected by the relational variables, it can be seen that customer participation is a major factor that can improve the relational variables again through the interaction process. For this reason, a service firm can seek to develop relationships with customers by drawing and utilizing their needs to exchange information and to interact in the service encounter.

The purpose of this study is to learn about the decision factors affecting utilization of elderly welfare center of the elderly living in Gimpo city. The reason of the study is that the elderly welfare center as a provider of general welfare services could not only thinking about the state policy but also need to consider about the inherent role and function of the elderly. Especially for these elders living in rural areas, although the number of elderly welfare centers of the whole country has greatly increased in last 10 years, the effect and function of the facility are almost the same and they are still lack of leisure activities. This issue become a serious problem nowadays. For the above reasons, this article conducts a social survey of 360 elderly people over the age of 65 who lives in the Gimpo city which is a rural-urban type city. The research method is to examine the relationship between the predisposing factors, enabling factors and need factors of Andersen's behavior model with binary logistic regression analysis and the decision tree analysis. The result of binary logistic regression shows the most of factors of Andersen's model is significant. The factors of age, gender, education level in predisposing factors; monthly income in enabling factors and the reserve for old life, the preparation of economic activity for old life in need factors are significant. Then the result of decision tree analysis shows the interaction between factors; when the education level in predisposing factors is higher, the possibility of using of elderly welfare center becomes bigger. Also as the level of healthy promoting preparation in the need factors gets lower, the possibility of using of elderly welfare center still becomes bigger. Although differences were found in the interpretation of the results of regression analysis and decision tree analysis, the results of this study can still provide support for the necessity of elderly welfare centers providing integrated welfare services.

As the service industry develops, service quality, customer satisfaction, and human resource management are considered priorities in modern management to maintain a company's growth. Therefore, understanding the strategic importance of service marketing is an essential task for modern companies. This study examined the relationship between the internal service quality of employees in the organization and customer orientation through organizational effectiveness. In the case of an airline, a service can be defined as an interaction between an external customer and an internal customer service provider. This interaction significantly affects the behavior and attitude of the employees. Based on the results, empowerment has a significant influence on the internal service quality, but it has no significant effect on customer orientation. As the relationship between department and employees improved, the more confident staff showed an improved ability to perform their work. Therefore, it is important that the organizational structure and the reporting system are as concise and clear as possible to allow employees to accurately recognize the authorities and responsibilities assigned to them and have autonomy and discretion in the framework.

Recently the telemedicine platform firms which have been temporarily permitted since COVID-19 outbreak have increasingly provided online prescription drugs delivery, causing concerns among incumbent providers of medicine, some of whom began to take aggressive actions again them. In this study, using game theoretic market entry - deterrence model, we show that although the incumbent medicine provider can effectively deter entry by the telemedicine platform firms by its preemptive action, accommodation could be a optimal action when telemedicine platform firms already have penetrated the market with their being permitted to do business due to the COVID-19. However, for the incumbent to cooperate for the successful change in the retail market for medicines, policies like placing a ceiling on the maximum number of taking prescriptions by the pharmacists a day in the telemedince platform network, providing favorable exposure of community pharmacists on the telemedicine platform user interface, and allowing community pharmacies to participate as shareholders of the telemedicine platform firms in its initial public opening of capital, are suggested.

Small area variations in health care utilization have long been studied as an important issue related to boto cost containment and quality assurance. This study was conducted to investigate if variations in hospital services across small geographic areas in Korea existed. The claims data of the fiscal year 1992 obtained from the regional health insurance societies were used for the study. Main findings of the research can be summarized as follows : 1. Extremal Quotients(EQ) of hospital expenditure per capita and hospital days per capita varied among diagnosis types. The EQ ranged from 2.05(cataract) to 41.67(pneumonia) in hospital expenditure per capita and from 1.86(cataract) to 45.89(pneumonia) in hospital days per capita. The diagnosis groups which showed high variation were pneumonia, cephalo-pelvic disproportion, gastritis and duodenitis, fracture of rib, and acute bronchitis. Those which showed low variation were acute appendicitis and cataract. 2. The EQ level of admission rate was different in terms of diagnosis types, ranging from 2.57(catarct) to 44.45(pneumonia). The variations were high in medical disorders such as pneumonia, oephalo-pelvic disproportion, gastritis and duodenitis and acute bronchitis, while relatively low in surgical conditions such as acute appendicitis and cataract. 3. As an indicator of service intensity, the EQ of expenditure per admission ranged from 1.67(acute appendicitis) to 31.27(essential hypertension). The diagnoses which had high variation were essential hypertension, gastric ulcer, whereas those which had low variation were cephalopelvic disproportion and acute appendicitis. With regard to hospital days per admission, the EQ ranged from 1.55(acute appendicitis) to 28.13(gastric ulcer) by diagnosis types. The diagnosis groups with showed high variation were gastric ulcer, essential hypertension, and acute bronchitis, whereas those with low variation were cephalo-pelvic disproportion, intervertebral disc disorders, and acute appendicitis. Both the expenditure and hospital days per admission showed lewwer variations than the expenditure per capita, hospital days per capita and admission rate. 4. Comparing patterns of variation in utilization indices, diagnoses such as essential hypertension, gastric ulcer, fracture of rib showed higher variations in expenditure per admission than in admission rates, whereas diagnoses such as pneumonia, cephalo-pelvic disproportion and gastric ulcer showed higher variations in admission rate than expenditure per admission. These findings suggest that wide variations existed in several diagnoses groups across small areas in Korea. Further research should be performed to investigate factors related to small area variations including provider behavior.
