Recent economic slump is making the construction industry's overall construction business environment worse. Contractors which are under the legal management and/or walk out are to the brink of 25 companies according to the Construction association of Korea released in 2011. It means that existing construction companies are required to transform the fundamental ideology of existing operation framework, and besides, existing companies should be transformed to service industry in order to proceed further into the developing future industries. In this study, it will be chosen the internal marketing related factor like 'Satisfying employees, internal customer, are the first thing to do in order to satisfy external customer.' which is about existing service industry field before its implementation in construction companies. In addition, appropriateness test will be performed including both interactions between each of the factors affect mutually and looking into any management improvement effects on contractors. And also, this proposal is suggested by approaching with internal marketing strategy which is both paradigm shift for customers by construction company members and another internal communication way as a means of overcoming the crisis of overall construction industry under currently happening.

Using the theory of attribution, this study investigates the determinants if controllability and explores underlying dimensions of online information credibility, and then investigates if the credibility of online information influences the users' intention to use the online information for evaluating or judging the involved products. Moreover, as a research attempt to investigate the impacts of online information credibility, this study examines whether the main effect of perceived online information credibility on the intention of using online information to make a decision of purchase is mediated by both perceived risk and perceived usefulness. A total of 287 survey forms were collected from online consumers. We examined reliability by exploring internal consistency of the multiple item scales in the overall sample. Convergent and discriminant validity were also examined for evidence of construct validity. Then, PLS technique was employed to test the research model. As a result of analyzing data from a dataset of 287 responses via PLS technique, it is found that (1) both sources (controllability and stability) of perceived credibility are significantly associated with both perceived risk and perceived usefulness, and (2) perceived risk as well as perceived usefulness partially mediate the link between the two sources of credibility and intention to use. The findings of this study also suggest that the two dimensions of online information credibility influence information recipient's intention to use. Moreover, the online information including descriptions about controllability and stability can trigger potential consumers to perceive risk about consumption of the informed products and services. Therefore, providing online information with highly described controllability and stability can increase not only the credibility of the online information itself, but also the intention to use the online information through perceived risk and usefulness.

The purpose of this study was to investigate tangible clues influence on perceived risk and overall satisfaction of customers at family restaurant in South Korea. In this research overall CFA and SEM were employed to analyze the data. Tangible clues were divided to 3 factors and perceived risk to 6 factors. Tangible clue 1 'physical evidence', had negative(-) influence on financial risk(p<0.01), performance risk(p<0.01) and psychological risk(p<0.001). Tangible clue 2 'employee' affected negatively(-) time risk(p<0.001), performance risk(p<0.001), psychological risk(p<0.01) and social risk(p<0.001). And tangible clue 3 'service process' influenced negatively(-) physical risk(p<0.01), time risk(p<0.05), financial risk (p<0.001) and performance risk(p<0.01). And among customer's perceived risks, 3 factors(time risk~p<0.001, performance risk~p<0.001, social risk~p<0.001) influenced negatively(-) their overall satisfaction. Through these results, it appears that customers perceive various tangible clues and risks at family restaurants. And they are likely to satisfy or dissatisfy according to their perceived risks. As a result, food service companies need to research various customers' perceived risks as important marketing strategy, and reduce them for increase and induction of customers' satisfaction.

This study attempts to investigate the spatial characteristics of medical hospital distributions in Korea. For the purpose we examine the inter- and intra regional variations in the distributions of clinics by specialty subject. In particular, we analyze the distribution patterns of Location Quotients of clinics for 12 specialty subjects in Seoul. Medical services tend to be concentrated on the large cities, especially in the Metropolitan Seoul Area. In particular, clinics and medical doctors as well as large scale general hospitals have been strongly concentrated on the Metropolitan Seoul area. These circumstace may be related with the fact that medical hospitals are established and operated by private sector in Korea, and thus they attempt to find their location where they can get maximum profit. The distribution patterns of clinics of 12 specialty subjects can be classified to several characteristic patterns. In particular, clinics of plastic surgeon tend to be strongly concentrated on the Gangnam area in Seoul. Finally, clinics of plastic surgeon tend to be located on the areas near the subway stations along the subway Line 2 and Line 3 in the beginning. The existence of plastic surgeons turns out to have significant role on determining the location for the newly opening plastic surgeons in the later. Therefore, their agglomeration has been getting more strongly.

It is required to consider pricing and non-pricing factors and external economy in order to achieve the objects of physical distribution system in a port. Recently, among the three factors, much attention has been paid to non-pricing factor in the system. Although physical distribution service in a port(PDSP)has been frequently mentioned in documents and literature related to port and shipping studies, few study on it has not been systematically and scientifically made due to the following problems; $\circ$ there are not proper criteria to evaluate level and quality of PDSP and as a result it is difficult to set up a unified standard for doing so. $\circ$ algorithms to evaluate problems with complex and ambiguous attributes and multiple levels in PDSP are not available. This thesis aims to establish a paradigm to evaluate PDSP and to abvance existing decision making methods to deal with complex and ambiguous problems in PDSP. To tackle the first purpose, extensive and thorough literature survey was carried out on general physical distribution service, which is a corner stone to handle PDSp. In addition, through interviews and questionnaire to the expert, it have extracted 82 factors of physical distribution service in a port. They have been classified into 6 groups by KJ method and each group defined by the expert's advice as follows; a. Potentiality b. Exactness c. safety d. Speediness e. Convenience f. Linkage Prior to the service evaluation, many kinds of its attributes must be identified on the basis of rational decision owing to complexity and ambiguity inherent in PDSP. An analytical hierarchy process (AHP) is a method to evaluate them but it is not applicable to PDSP that have property of non-additivity and overlapped attributes. Therefore, probablility measure can not be used to evaluate PDSP but fuzzy measure is required. Hierarchical fuzzy integral method, which is merged AHP with fuzzy measure, is also not effective method to evaluate attributes because it has vary complicated way to calculate fuzzy measure identification coefficient of attributes. A new evaluation algorithm has been introduced to solve problems with multi-attribute and multi-level hierarchy, which is called hierarchy fuzzy process(HFP).Analysis on ambiguous aspects of PDSP under study which is not easy to be defined is prerequisite to evaluate it. HFP is different from algorithm existed in that it clarified the relationship between fuzzy measure and probability measure adopted in AHP and that it directly calculates the family of fuzzy measure from overlapping coefficient and probability measure to treat and evaluate ambiguous and complex aspects of PDSP. A new evaluation algorithm HFP was applied to evaluate level of physical distribution service in the biggest twenty container port in the world. The ranks of the ports are as follows; 1. Rotterdam Port, 2. Hamburg Port, 3. Singapore Port, 4. Seattle Port, 5. Yokohama Port, 6. Long beach Port, 7. Oakland Port, 8. Tokyo Port, 9. Hongkong Port, 10. Kobe Port, 11. Los Angeles Port, 12. New york Port, 13. Antwerp Port, 14. Felixstowe Port, 15. Bremerhaven Port, 16. Le'Havre Port, 17. Kaoshung Port, 18. Killung Port, 19. Bangkok Port, 20. Pusan Port

Thanks to current development of many search engines and web technologies, a new semantic searching technology appears, featuring giving a relevant meaning to the keyword beyond the previous keyword search service. On the wave of advance of various search engines, the enhancement of OASIS offered by KIOM is needed as well. To do this, KIOM examined demographic and sociological analysis on their position, status, and career, the convenience of OASIS, and the value of papers offered in OASIS from members who have ever used it. Furthermore, the importance of each area involved in oriental medicine is also examined in terms of a new direction for OASIS improvement. Based on the result of the user survey, it turned out that not only an automatic search system that can find meaning of chinese character-centered key words but also a Authority-system which can distinguish homonym beyond simple keyword search system should be introduced quickly. Also, we reached the conclusion that it is necessary to interconnect a citation index information on references with laboratory information of the agencies concerned and interconnect major web sites around the world by using Open API. OASIS is the only domestic web site for offering papers that cover oriental medicine. Therefore, if requirements about the site in oriental medical circles are analyzed sufficiently and the problems of its information search system are improved, OASIS is expected to play a critical role in the development of oriental medicine.

Due to not only proven stability and reliability but a significant investment and years of accumulated -experience and knowledge, legacy systems have supported the core business applications of a number of organizations over many years. While the emergence of Web-based e-business environments requires externalizing core business processes to the Web. This is a competitive advantage in the new economy. Consequently, organizations now need to mine the business value buried in the legacy systems for reuse in new e-business applications. In this paper we suggest a systematic approach to mining components that perform specific business services and that consist of the legacy system's assets to be leveraged on the modem platform. The proposed activities are divided into several tasks. First, use cases that realize the business processes are captured. Secondly, a design model is constructed for each identified use case in order to integrate the use cases with the similar functionalities. Thirdly, we identify component candidates from the design model and then adjust the component candidates by considering common elements among the candidate components. And also business components are divided into three more fine-grained components to deploy them onto J2EE/EJB environments. finally, we define the interfaces of components which provide functionalities of the components as operations.

Purpose - Past research has not given much attention to the roles of consumers' social relationship type in the effects of justice type of service failure recovery alternatives on their satisfaction to the alternative exposed to them. Current research aimed at exploring the moderation role of consumers' social relationship central versus peripheral in the effects of justice types of service failure recovery alternatives on the recovery satisfaction, and this research also explored whether the level of satisfaction to interaction justice-focused alternative are significantly different between the two, their social relationship central and peripheral relationship. Research design, data, and methodology - 2(social relationship central versus peripheral) between-subjects design was employed. 50 participants for each experimental group there were. Participants of each group took forceful steps in choosing one between the procedural justice-focused alternative and the distribution justice-focused alternative. χ²-analysis was used to verify that the number of choosing each alternative becomes different between the two experimental groups, and a one way ANOVA was used to verify that the extent to which participants are satisfied to the alternative chosen by them becomes different between the two groups. Results - The number of participants choosing procedural justice-focused alternative at the group of social relationship central was larger than that at the group of social relationship peripheral, whereas the number of participants choosing distribution justice-focused alternative at the group of social relationship peripheral was larger than that at the group of social relationship central. And the level of satisfaction to procedural justice-focused alternative at the group of social relationship central was higher than that at the group of social relationship peripheral, whereas the level of satisfaction to distribution justice-focused alternative at the group of social relationship peripheral was higher than that at the group of social relationship central. In addition, the level of satisfaction to interaction justice-focused alternative was not significantly different between the two groups. Conclusions - Marketers should give attention to the type of justice when developing alternatives by which consumers' service failure can be recovered. They should suggest procedural justice-focused alternative to consumers under social relationship central, whereas they should develop distribution justice-focused alternative for consumers under social relationship peripheral. And in the process of recovering service failure they also should focus on interaction justice.

Anonymity is the one of main reasons for substantial improvement of Internet. It encourages various users to express their opinion freely and helps Internet based distributed systems vitalize. But, anonymity can cause unexpected threats because personal information of an online user is hidden. Especially, distributed systems are threatened by Sybil attack, where one malicious user creates and manages multiple fake online identities. To prevent Sybil attack, the traditional solutions include increasing the complexity of identity generation and mapping online identities to real-world identities. But, even though the high complexity of identity generation increases the generation cost of Sybil identities, eventually they are generated and there is no further way to suppress their activity. Also, the mapping between online identities and real identities may cause high possibility of losing anonymity. Recently, some methods using online social network to prevent Sybil attack are researched. In this paper, a new method is proposed for extracting a user's system-wide Sybil-resistant trust value by using the properties embedded in online social network graphs. The proposed method can be categorized into 3 types based on sampling and decision strategies. By using graphs sampled from Facebook, the performance of the 3 types of the proposed method is evaluated. Moreover, the impact of Sybil attack on nodes with different characteristics is evaluated in order to understand the behavior of Sybil attack.
