This paper proposes the RDMS(Rough Set Theory based Disease Monitoring System) which efficiently manages diseases in Healthcare System. The RDMS is made up of DCM(Data Collection Module), RDRGM(RST based Disease Rules Generation Module), and HMM(Healthcare Monitoring Module). The DCM collects bio-metric informations from bio sensor of patient and stores it in RDMS DB according to the processing procedure of data. The RDRGM generates disease rules using the core of RST and the support of attributes. The HMM predicts a patient's disease by analyzing not only the risk quotient but also that of complications on the patient's disease by using the collected patient's information by DCM and transfers a visualized patient's information to a patient, a family doctor, etc according to a patient's risk quotient. Also the HMM predicts the patient's disease by comparing and analyzing a patient's medical information, a current patient's health condition, and a patient's family history according to the rules generated by RDRGM and can provide the Patient-Customized Medical Service and the medical information with the prediction result rapidly and reliably.

The purpose of this study is to understand consumer values derived from products by the contemporary consumers, as the meaning of a product is extended from the functional utilities to the mediums of fulfilling consumer values. Consumer values have been researched from the marketers' perspectives and, thus, the scales to measure consumer values tend to be too abstract and not always reflective of the consumers' perspectives. Holbrook's typology of consumer values is utilized and the products are classified into four groups according to the product characteristic of the utilitarian versus hedonic, and the consumption spaces of the indoor and outdoor. The findings are as follows. First, the values of efficiency, excellence, ethics, and spirituality are more likely derived from utilitarian products, while the value of play is more likely derived from the hedonic products. Second, the values of efficiency, excellence, and ethics are more likely derived from the indoor products, and values of playfulness, esthetics, status, and respect are more likely derived from the outdoor products. Third, the most frequently mentioned values are the efficiency, playfulness, and status. Fourth, the list of products answered as being representative for four types of products are short to include obvious products such as TV, mobile phone, computer, car, refrigerator, and MP3 player. Both the utilitarian and hedonic values are derived from TV, computer, and mobile phone, while the utilitarian value from refrigerator and car, and the hedonic value from MP3 player, digital camera, and game consoles. The results imply that consumer values should be carefully understood and reflected in developing new products in order to successfully fulfill consumers' underlying needs and requirements.

In order to maximize customer satisfaction and provide differentiated customer-oriented marketing strategies, it is important to understand the essence of consumer behavior and characteristics of their market segmentation. Therefore, this study explored the relationships among five different food-related lifestyle (i.e., health, fashion, taste, economy and safety oriented), positive emotion, and satisfaction. An analysis of 338 samples drawn from college students who visited coffeehouse at least once in the previous months was performed. The results revealed that, taste, economy, and safety oriented lifestyle significantly affected positive emotion, and positive emotion significantly affected satisfaction. The findings highlight the significant role of coffeehouse customer food-related lifestyle toward positive emotion in the formation of satisfaction, and therefore generate theoretical and practical implications for the coffeehouse industry.

This study was conducted to find the influence of menu select attribute on consumer preferences and satisfaction as perceived by Japanese restaurant consumers. Survey method was employed and distributed during January 1 to January 31, 2016 from who have an experience in Japanese restaurants located in Busan and Gyeongnam. First, the quality of the menu (${\beta}=.444$, p<.001), menu design(${\beta}=.425$, p<.001), select menu motivation (${\beta}=.147$, p<.001) positively impact on consumer preferences. Second, consumer preference significantly and positively influence on customer satisfaction. Third, the quality of the menu (${\beta}=.650$, p<.001), menu design(${\beta}=.120$, p<.001), select menu motivation (${\beta}=.263$, p<.001) positively impact on consumer satisfaction. Finally, partial mediating effect of consumer preference was identified between select attributes and consumer satisfaction.

Non-face-to-face real name verification policy that financial authorities announced, in order to secure a face-to-face or more of accuracy, are in principle of multi check. The business model and legal entities of Internet banks is different from existing Internet banking. Relpacing real name verification from face-to-facd to non-face-to-face while maintaining the structure of identification can not only cause inconvenience to a first time member, but also can be more vulnerable to verious security risks. In this study, to evaluate a service level of a bank of the Internet, and provide an improved identification of the structure such that the registration and use of differentiated services is performed in accordance with the evaluation. In addition, the security that may occur with respect to Bank of the Internet to establish a vulnerability and attack model, the results of the analysis of the safety of the step-by-step security attributes and services of the authentication medium of each attack model, existing the safer than Internet banking, confirmed the usefulness in user registration guide.

The fire organization of civil servant is a specified public official job which traditionally is characterized by conservative attributes, highly emphasized with a hierarchical culture and the order from higher position. Such a special condition of the fire organization is seemingly regarded as a prerequisite of the occurrence especially prevalent of the systematic discord rather than the other system of a civil servant such as a common administrative job. The conflict among fire officials which is caused by the variety of effort that has been input in pursuit of making a desirable structure does not in progress or even though it dose, weakened by a counterbalance. Therefore, the goal of this research is inducing a plan to revitalize the fire organization through the corroborative analysis of the conflict between indoor duty and outdoor service ones. That is the reason of the disagreement, the device of getting rid of discord and so on.

NGN is a packet-based converged network to support session and non-session services in QoS-enabled broadband transport network. QoS based resource control must be defined to support differentiated services for various network users in NGN. We designed and implemented DIAMETER protocol as the Rs interface, and also defined mapping rules between DIAMETER information elements and SDP(Session Description Protocol) attributes for QoS based resource control in NGN. We selected and implemented DIAMETER protocol among alternate resource control protocols in ITU-T as the Rw interface because of simple interworking method with Rs interface and adequate AAA functionality. We defined mapping rules of messages and information elements between Rs and Rw interfaces for resource control from a service layer to a transport layer. Based on the mapping rule of QoS information elements and the interworking method between Rs and Rw interfaces, we built up a test-bed that support differentiated delivery services.

Database Integration problems has been recognized as a critical issue for effective logistics service in logistics environment. However, researches related to effective methodology for this have been studied theoretically in the DB schema integration, are insufficient in the side of the system realization. The aim of this paper is to present a schema integration technique to integrate DB using XML( eXtensible Markup Language) in the part of practical DB integration, a quantitative methodology for the identification of conflict that is a representative problem on database integration. To achieve this aim, we extracted the entity name and attribute name from DB schema and suggested a quantitative methodology to easily fine name conflict that frequently give raise to a trouble when schema integration, based on the level of semantic similarity between attributes and entities.

This study aims to investigate the current states of branch systems of public libraries in Korea and to find implications to improve such systems. Nationwide surveys to directors and branch directors of public libraries were conducted along with case studies on major local areas. It was revealed that the duties for each branch were rationally assigned in functional perspectives. The result also revealed that the branch systems of provincial office of education were planned in an inappropriate manner without considering their functional attributes. Other findings included (1) public library branches were necessary to be located in local governments based on the hierarchal structure of the following: a central library, a main local branch. a mobile library unit. public mini-library and deposit station ; (2) Saemaul mobile library and private mini-library service were the most effective when they were provided in conjunction with public library branches.

Recently, with the development of IT technology, authentication methods of users using cloud services have been diversified. However, research on providing authentication information of a user using a cloud service securely according to authority has not been make until now. In this paper, we propose a key establishment protocol which can perform split authentication using secret key and access control key according to the role authority of user in Intra cloud environment. The proposed protocol generates the access control key and secret key of the user by using the attributes of the user and the generated random number($t_1$, $t_2$), and classifies the roles according to the user's authority after generating the key. Unnecessary operation processes can be reduced. As a result of the performance evaluation, the proposed protocol guarantees the security against various type of attacks that may occur in the cloud environment because the user is authenticated by dividing the access control key and secret key. The size of the ciphertext used to establish the key could be reduced by ${\sum}+1$ more than the existing protocol.
