The field of the web service orchestration introduced to generate a valuable service by reusing single services. Recently, it suggests rule-based searching and composition by the AI (Artificial Intelligence) instead of simple searching or orchestration based on the IOPE(Input, Output, Precondition, Effect) to implement the Semantic web as the web service of the next generation. It introduce a AOP programming paradigm from existing object-oriented programming paradigm for more efficient modularization of software. In this paper, we design a dynamic web service orchestration and invocation scheme applying Aspect-Oriented Programming (AOP) and Reflection for Semantic web. The proposed scheme makes use of the Reflection technique to gather dynamically meta data and generates byte code by AOP to compose dynamically web services. As well as, our scheme shows how to execute composed web services through dynamic proxy objects generated by the Reflection. For performance evaluation of the proposed scheme, we experiment on search performance of composed web services with respect to business logic layer and user view layer.

The purpose of this study is to get implications on teacher education curriculum according by analyzing pre-service secondary teachers' difficulties during student-teacher practice. Fifty-six pre-service secondary teachers were requested to write anecdotes about their student-teacher practice. Pre-service secondary teachers revealed that they had experienced the most difficulties relating to instruction teaching. They answered that they had especially comprehended inducing interest in diffcult learners, attention, appropriate composition of questions, and learners' understanding levels. Pre-service secondary teachers showed that they had tried to control students in experiment instruction. Also, they demonstrated that time for guidance counseling had been insufficient. They were dissatisfied with the content and level of counseling. Therefore, we need to improve teachers' college curriculum by performing student-teacher practice and feedback. We especially need to systematize teachers' college curriculum on the basis of developing standards of science teachers' expertise.

There has been an increase in the interest of applications that use a combination of both pervasive computing technology and context-aware technology. This application based on the development environment along with the support of developing context-aware applications is now being researched thoroughly and by many. The service management system provides services that are needed for context-aware applications. This system is an integral part of the developmental environment of context-aware applications. But there is a restrictive matching based on ontology that uses simple syntactic matching or a plain type of service used in previous researches. And there is also no consideration for context-aware information. Also, if the user is unable to find a service that is satisfactory, or is a service which a user does not desire, they may use a service which is composed of other existing services. This paper proposes a service management system based on context-aware information. The proposed system enables the accurate finding of services by considering semantic matching methods based on ontology and context-aware information. If the user does not find a service that is helpful in the service registry, it can provide the service list to enable other existing service compositions, by providing the functionality of these service compositions. As a result, the experiment of the system proposed has shown that the system properly supported the service discovery based on context-aware information and service composition.

In ubiquitous computing environments, users want to receive the robot services regardless of various physical status or devices such as time, place, various sensors, and high-performance servers. Thus, the ubiquitous service robots have to provide users with automated services according to situational information that they properly recognize. Beyond these problems, robot software has to establish a foundation to support the functions with the network infrastructure that are not able to be solved by a single independent resource. On the basis of a robot middleware that is capable of minimizing dependencies among hierarchy structures, the robot software also has to provide execution environment to control the flow of robot application services. In this paper, we propose a layered architecture to provide users with automated services through ubiquitous robots. The proposed architecture is based on CAWL (Context-Aware Workflow Language) and RSEL (Robot Services Execution Language). CAWL easily represents the flow of robot services from user application service levels, and RSEL is able to support the composition and reusability of robot services through abstraction of robot device services. In our experiments, we applied the proposed architecture to an example of "booth guide robot service".

This nutritional survey was conducted in February 25, 1999, in order to investigate the nutritional knowledge, dietary attitudes and nutrient intakes of dietitians living in Kangwon area. Subjects consisted of 250 dietitians, with 184 in school food service, 14 in hospital food service and 52 in institution food service. Data were analyzed for frequencies, means, t-test, $x^2$-test, ANOVA and Pearson correlation using SPSS PC Package. The results obtained are summarized as follows: The average nutritional knowledge score was 10.15 out of possible 15 points, and dietary attitude score was 67.93 out of 100 points. The correlation between nutritional knowledge score and dietary attitude score was lowly(${\gamma}=-0.25$). Nutrients consumed below the Korean RDA were energy (78.77%), Ca(90.5%), Fe(83.70%) and nutrients consumed above the Korean RDA were protein(110.83%), P(140.21%), vit.A(163.94%), $vit.B_2$(126.37%), niacin(121.12%) and vit C(231.86%). Carbohydrate, protein and fat ratio on energy composition was 63%:17%:20%. The nutrient density among 3 groups of dietitian was not significantly different.

This study sought to identify unique semiotic codes of Korean cuisine, including table settings, service styles, service ware selection, cooking techniques, and the logic behind menu composition. This research also aimed to verify that yangnyomjang reflects the code of Korean food culture. One of key findings from this study was that hidden codes of Korean food were found in their daily set-up for bapsang (dining table), which was found to decodify polysemic characteristics with an emphasis on harmony. These semiotic codes were influenced by the yin and yang philosophy and impact dining activities in our daily lives. Korean bapsang, composed of bap (rice), guk (soup) and banchan (side dishes), helps every individual diner share the semiotic codes of Korean cuisine within the context of paradigm and syntagm. Yangnyomjang, a major component of the Korean menu, also represents a unique code of Korean cuisine in its structure, main ingredients, production, and usage. This study also mathematically verified that a synchronic table setting of Korean cuisine provides diners with more opportunities for potential flavor combinations, compared to the Western service setting.

This study empirically analyzed the effects of the Top Management Team (TMT) on organizational performance. We verified whether the age heterogeneity, job heterogeneity (core career, core function and major), and process (communication and integration) of the TMT affect organizational performance (management performance and healthcare service quality evaluation level). We collected data about 473 members of the 2006 TMT in 81 medical institutions. We also utilized statistics of organizational performance from the Ministry for Health, Welfare and Family Affairs and the Korean Institute of Hospital Management. Results of the study showed that the age heterogeneity of TMT exerted a negative effect on the healthcare service quality evaluation level, while the process exerted a positive effect. However, the age heterogeneity, job heterogeneity, and process had no influence on management performance. We discussed the implications of such outcome of the investigation in comparison with the former studies on TMT and organizational performance, and presented its restrictions and future plans.

This paper presents our performance evaluation after the way of minimizing waiting times between channel switching for eMBMS(evolved Multimedia Broadcast/Multicast Services) technique in LTE-Advanced systems. Existing composition of MBMS using IGMP(Internet Group Management Protocol) transfers the data with Multicast from BM-SC(Broadcast Multicast Service Center) to eNB(evolevd Node B) and with Broadcast from eNB to UE(User Equipment). Therefore, in case of channel switching, IGMP Join report should be transferred to BM-SC and then wait user's contents to be retransferred from eNB. To achieve this, Subscriber Channel technique of priorities is used for minimizing waiting times between channel switching as UE broadcasts favorite channels in advance.

The purpose of this study was to provide useful information which would help web-site planning and design, product composition, and service of internet shopping malls. The sample consisted of 693 university students who had visited(Ed- in this case 'visit' means to enter an internet site; note also that the past perfect tense already conveys the meaning of 'experience') internet fashion shopping malls or purchased clothing through internet. Data were analyzed by factor analysis, frequency, t-test, and ANOVA(LSD) using SPSSWIN. The results were as follows： 1) The evaluative criteria of internet fashion shopping malls could be categorized by 4 factors： product presentation method, design, product information, sales promotion ＆ additional service; the first of which was found to be the most important. These criteria showed significant differences according to the period and time of access. Furthermore, the degree of consideration for these criteria was high, whereas the degree of satisfaction was low. 2) The evaluative criteria of clothing could be categorized by 6 factors： general characteristics of products, wearing comfort ＆ ease of management, popularity ＆ status symbolism, service, aesthetics, and textiles materials; the first of which was found to be the most important. These criteria were significantly different according to the periods, time, and purposes of access, and purchase experiences.
