The IP Multimedia Subsystem(IMS) is an architectural framework for delivering IP multimedia services to mobile users. In order to guarantee the reliability and Quality of Service(QoS) of a variety of multimedia services, we need a new evolutionary approach that maintains the IMS based signaling platform which can perform the processing of flow through distributed controllers. Software Defined Network(SDN) is an architecture purporting to be distributed, dynamic, cost-effectives as well as adapting and seeking to be suitable for the high-bandwidth, dynamic nature of today's applications. It requires some methods for the control plane to communication with the data plane. One of such mechanisms is OpenFlow which is a prominent standard protocol and interface that is responsible for managing the network resources by using the remote SDN controller. In this paper, we propose a straightforward approach for integrating SDN technology together with the IMS architecture. Therefore we propose and construct a combined architecture model that performs flow processing using OpenFlow via the IMS based signaling platform, which maintains the existing telecom call service. Additionally, we describe some relevant experimentation results from the proposed architecture.

Consumer health information is receiving more attention than ever before. This growing attention can be linked to the Internet and to people seeking more information on health topics. The purpose of this study is to suggest a design of the Knowledge management system for medical information services in a public library. As theoretical backgrounds, it discusses the issues regarding to the medical information services in a public library, knowledge management and knowledge management system. After that, 12 medical information sites are analyzed then the planning and the main menu of a medical information site for a public library are described. Finally, the model of the knowledge management system for a public library with 5 sub-systems are suggested: 1) knowledge creation system, 2) technology support system, 3) training system, 4) community service system, 5) knowledge sharing and network system. This system based on knowledge management will help provide the users high quality of medical information.
Due to consumers' preferences for seeking a quality life and having more leisure time, comfortableness became a major criteria for selecting clothes for all age groups. This is why consumers' interests in knitwear increased recently. The purpose of this study is to analyze the knitwear consumption patterns such as style preferences, and consumer satisfaction with knitwear. Particularly, differences in age groups of consumers were analyzed. Data from 463 men and women participated in the study. Results indicated that consumers wear knits once or twice a week in average. After two to three years of consumption, they discard the knitwear. Among various apparel product categories, Consumers selected Cardigan to be the preferable knitwear product category. They preferred 100% cotton and achromatic or gray/brown color with solid fabrics. In general, consumers were most satisfied with colors and least satisfied with laundering of knitwear. Older consumers preferred knitwear to woven products, preferred pull-over style and valued feelings of softness and comfortableness when wearing knitwear. There were more differences in dissatisfaction factors than satisfaction factors according to the consumer age groups.

Modern male has displayed an increased desire to express their social influence and image, and the male fashion market has had to provide various styles and images to fill these needs. The current domestic menswear market, however, is unable to satisfy the needs of male consumers who have a need for diversity in a rapidly changing society; more segmented fashion images and styles are needed. The purposes of this study are to classify fashion images and to establish character of the types. This study was done by performing a literature review and a survey. This study proposed 10 categories of fashion style images. Men's fashion style is classified into the classic image, sophisticated image, urban casual image, chic modern image, mods modern image, basic casual image, ethnic image, avant-garde image, active & outdoor image, and street-kitsch image. In the case of the classic images, common in formal setting, men's formal wear is the main focus with the classic suit. The sophisticated image is that of a colorful formal wear seasoned with elegance. Urban casual image is contemporary image, and therefore is meant for city life wear. Chic and modern image conveys an urban image by seeking a simple and chic feel. Mods modern image is retro yet dandy, giving off a sense of youthfulness compared to the other classic images. Ethnic image expresses the exotic quality of folklore as the main representatives of the character casual wear. Avant garde image portrays strong character casual wear with oversized silhouettes or exaggerated details. Active & Outdoor image is leisure life wear conveying active, functional images. Street Kitsch image is men's street casual wear with graphic patterns such as pop art and graffiti. This study's significance lies in its presentation of fashion style data, which can be utilized in the design and marketing of fashion targeted to males.
Today, home health care services needs a linkage plan of the customized home visiting health service in public health center, the medical institute home health care service, and home visiting nursing service based on long term care insurance for the elderly program which acknowledges the independence and professionalism of the home health care services while minimizing overlap through linking the projects. So, this study was performed by applying the Delphi technique, which draws agreement from professional opinion, to determine a method to link home health care services in Korea. The results of this study are as follows. Specialists agreed on 24 important items within the two domains of institutional linkage and medical linkage. And the significance of this study is as follows. The 24 items deduced for the approved nursing service linkage plan are expected to improve the home health care service business system, enhance the quality of home health care service, and bring increased satisfaction for service recipients. Also, seeking ways to minimize overlap in service can increase the effectiveness of health care and public health management at a national level. In addition, it is considered that this will ultimately reduce public medical costs as well as improve home health care service.
The purpose of this study was to examine the attractiveness of local festival on local esteem of residents through the residents' satisfaction toward the festival. The survey was undertaken for four days during October 11 to 14 of 2013 in Dongnae, Busan. Two hundred twenty-three respondents were selected and invited to participate in this study. Results found a significant relationship between local festival attractiveness and festival satisfaction. The study also indicated that local community residents' satisfaction toward the festival had a significant, positive relationship with the residents' local esteem. Among the attractiveness factors, it was revealed that novelty-seeking and entertainment were more powerful stimulators. Also, analysis indicated that program quality, uniqueness, and convenience were also important for attracting local residents toward the festival. Theoretical and practical implication were discussed.
An increasing number of hospitals are seeking for new or mixed compensation strategies to improve the productivity of their medical staff in the struggle to provide high quality medical services at low costs amid the economic hardship. To motivate physicians toward the right direction, it is necessary to effectively evaluate their performance that provides a basis for compensation. However, productivity has been historically difficult to measure, particularly for physicians in academic medical centers who are expected to engage in research, education, and patient care simultaneously. The objectives of this study were to define performance measures of physicians and clinical departments in academic medical centers. to examine correlations between the measures. and to investigate factors affecting the measures. The performance data of 212 faculty physicians in 17 clinical departments in two university teaching hospitals affiliated to one medical school during the fiscal year 1994 was used for analyses. Patient care revenue, net profit. and adjusted number of patients were defined to measure the performance in patient care. and number of articles published in academic journals and research grant were defined for research activities. Both individual physicians' performance measures and per physician measures of clinical departments were analyzed. All measures defined to evaluate individual physicians' performance were positively related to each other. Clinical department and rank of faculty position were statistically significant predictors of revenue. and hospital. clinical department. and rank were significant predictors of net profit. journal publication. and research grant. Patient care measures defined to evaluate clinical departments were related to each other. so were research measures. and no significant correlations were found between patient care measures and research measures. Also found were large differences in department. ranks when clinical departments were evaluated by absolute per physician performance measures and evaluated by annual rate of changes in performance measures. These findings suggest that departmental performance measures opposed to individual performance measures are relatively free from problems of factors affecting the performance measures that are not in control of clinical departments or individual physicians. Results from the correlation analysis of departmental performance measures indicates that measures of research performance should be included in the evaluation to promote research activities in academic medical centers.
This study is aimed at checking on the extent of practical use of CAI in mathematical classes in secondary schools, thus seeking a way of activating the practical use of CAI, with computer networks being widely used for education. This research was conducted among some 120 mathematics teachers and 350 students in middle and high schools in the City of Kunsan, with questionnaires designed to survey the extent and effectiveness of the use of CAI, the teachers and students' awareness of CAI. In consequence, this research shows the following: The use of CAI was of considerable help in conducting mathematics classes, along with CAI used in a more effective way, but education materials concerning CAI were poorly managed and not a few teachers was negative toward the use of CAI in mathematics classes. In short, the practical use of CAI was unsatisfactory, probably due to the lack of application ability on the part of teachers caused by the perfunctory teachers' training. In conclusion, the practical use of CAI in classes can be activated as follows: CAI apparatuses and other teaching aids should be systematically managed by experts; high-quality CAI programs need to be developed to help teachers conduct effective classes; teachers should be positively encouraged to make practical use of CAI through teachers' training and a plan of obligating teachers to use CAI for one or two fixed class hours in a week may be strongly recommended.
Purpose - The purpose of the research is to identify the demographic characteristics of the customers with high private label purchase intention. According to the previous research demographics such as gender, age, income, and residence type affect private label purchase intention indirectly through psychographics rather than directly. For instance, higher income group is time pressured, price-insensitive, quality-sensitive, less likely to enjoy shopping utilitarian products, and less likely to be variety-seeking. The main contribution of this research is to verify the results found in the previous empirical foreign research using scanner data and to investigate the differences of the characteristics of private label users between Korea and the foreign countries. Research design, data, and methodology - In order to empirically test the proposed hypotheses, scanner data of a Korean major super center was analyzed. Results - Empirical results show that private labels are more favored by old people over 50s, dwellers in individual house, lower income group, and frequent store visitors. Age of 30s, dwellers in the apartment of 30 pyung, higher income group, and consumers who purchased a large amount are less likely to purchase private labels. Gender turned out not to affect private label purchase. It should be noted that there is a significant multicollinearity among independent variables. Conclusions - The research findings provide managerial implication for retailers' private label strategy. In general, retailers heavily send private label coupons to the customers with high purchase volume. According to the research, however, store visit frequency is much more positively associated with private label purchase than purchase amount. The study has some limitations. The samples are only consumers with private label purchase experience. The data were drawn from one store and only 8 commodity products were used for the analysis. Also, if more demographics were available, a more complete description on the private brand users' profile could have been derived. We propose the following future research. Research using the data including consumers without private label experience, research investigating direction of causality between private label loyalty and store loyalty, and research using hedonic private label products such as TV and PC could be promising.
Objectives : The objective of this study was to examine the academic informationseeking behavior and demand of the oriental medical researcher and to create the base data for establishing a library environment providing a high-quality information service which would aid the activity of such researchers, Methods : We distributed a questionnaire to the one hundred professors of the college of oriental medicine on the method of acquisition of information data, the environment of the library belonging to the college, and the like. Results : $\circled1$ The main class using the academic information service of oriental medicine was revealed to be researchers having a career of 10 to 15 years who had a domestic doctorate in oriental medicine. $\circled2$ When accessing information, the primary information resource used was academic journals. $\circled3$ Of the data forms mentioned in the study, periodicals was used most in number of printed data; computer databases among non-printed data. $\circled4$ The purpose of using an information resource was for performing a research project. $\circled5$ The path of acquisition of information was usually through the materials in their possession. $\circled6$ The greatest difficulty in gathering information was first of all the lack of information owned by the library, and next a lack of time and insufficient knowledge of information search and use. $\circled7$ More than 90% of respondents on the necessity of an expert library answered as "necessary" or "certainly necessary", indicating that the foundation of an expert library is very urgent. Conclusions : This study is beneficial for researchers engaged in oriental medicine to activate the use of information and also it will form a base of data for researchers to establish an environment of expert library in oriental medicine.
