The teacher plays important role at students' achievement. This study analyses science class by pre-service science teacher. An survey tool for analysis of science class was composed of the lesson, student behavior, teacher behavior and questioning techniques. Pre-service science teacher analyzed the science class of 100 science teacher. The results of this study showed that pre-service science teacher analysis that current science class did not focused on inquiry-oriented. The score of science class did not statistically significantly difference by science teacher's characteristics as gender and age. Also, they analyses that science teacher use concept-oriented and teacher-oriented method.

The purpose of this study was to compare the nutrient intake and foodservice satisfaction of homebound elderly had lunch at the local community centers by the difference of meal service charge. Two local community center with cons-regate meal service program located in Daegu and Gyongsan were selected; one with free of meal service charge (F), and the other with 500-1,000 won for meal service charge (K), According to the dietary assessment, energy and nutrient intakes of the 156 elderly subjects were as a whole under the Korean Recommended Dietary Allowance (RDA). Elderly or F service conte. showed higher $\%$ RDA for the selected nutrients and MAR (mean adequacy ratio) than those of K service center (p<0.001). Participants were satisfied with most of the congregation meal service from community conte. with different reasons such as 'tasty (K service center)' and 'free of charge (F service center)'. In conclusion, elderly had the lunch at the community center with free of meal service charge was poor nutrition status and lower socioeconomic level than the other type of community center in this area. Therefore, healthy menu for elderly should be developed and managed by professional dietitian, as well as its impact on health status of this group, and congregate meal service system might be extended to the homebound elderly of whole community with free of charge.

As medical service industry is transformed into the market centered on consumers, medical service quality patients recognize is emphasized as the powerful means to ensure competitive advantage among hospitals in the fierce medical markets. Many researches have been done on the definition of medical service quality, developing a scale to measure it, patient satisfaction, hospital repurchase and oral transmission intention, but integrated studies have not been done sufficiently on the patient' cognitive emotional aspects. For these research purposes, based on service relation, service quality, physical surroundings, human services, corporate reputation, service value, emotional response, customer satisfaction and repurchase intention, this paper suggests a theoretical modeling composed of hypotheses on the relations of each theoretical variable. In addition, the moderating effect of service relationships is investigated based on the structural equation model.

This study investigated the university proffssors', pre-service teachers' and in-service teachers' perceptions of the specialized science education courses in the 11 national universities of education in Korea, analyzed their perception differences, and made suggestions the future directions for the specialized courses. For this study, 46 university professors, 402 in-service teachers, and 336 pre-service teachers were participated nationwide. The results show that there were significant differences in their perceptions between the three groups. For university professors, for example, the acquisition of science content knowledge appeared to be the most important objective of the courses, whereas the other groups preferred the acquisition of more practical knowledge and skills that they could easily use and apply in their classroom teaching later. The university professors tended to think that the science specialized courses would be very useful to the teachers' teaching and contribute to developing their professionality. On the contrary, the in-service and pre-service teachers tended to think that the courses would be not so useful because science theories construct the courses rather than practical knowledge. The implications of these findings are discussed in relation to the future science teacher education.

Scholarly information service is compared with internet portal services for object of use, information attributes and target users. It is not popular service, so scholarly information service providers need to have distinguished marketing strategy. KISTI service development team has performed on-site training for end users in major customer institutions in 2008. This study shows the effect of scholarly information service on-site training and user's preference of service promotion in specialized information service field.

The advance in Service-Oriented Architecture (SOA) and web services has led to the development of new types of a system in which heterogeneous service components can connect and compose to solve a complex business problem. In the SOA, even though these service components are valid in their functionality, there is a need to test their behaviors when those services are composited. In recent years, WS-BPEL has received a wide acceptance as a means of integrating distributed service components. To test the composite service, the existing testing techniques have been focused on the functional features based on the WS-BPEL process. However as SOA approach is applying to real-time software development, the performance of composite service becomes one of important issues. This paper proposes a technique to the performance testing of a composite service with WS-BPEL extension which combined with the concept of aspect. Our WS-BPEL extension has been made towards annotating aspect component which is measuring the response time of the composite service. This paper also explains the procedure of performance testing with on-line transaction system. Our technique can apply to choose an adequate component in service composition with considering the performance among several candidate web service components.

Purpose - This study aimed to develop a new practical and universally applicable service quality model by improving the service quality measurement model proposed by many previous studies. Research design, data, and methodology - An in-depth analysis on what influences such service quality model had on the improvement effect of service quality, and Service Evaluation Model("SEM"), which was revised from the existing service quality measurement model, was developed. The model is divided into the two integrative categories: First, activity, that is the group of service-related activities. Next is item, the group of service-related objects. The level of service is evaluated for each category via survey questionnaire on service level evaluation. Based on the model, SEM has visibility by structuring the whole service industry. Results - For the application of the new service quality model, this study attempted to examine the appropriateness of the newly proposed service quality model by applying it to retail service field. Conclusions - As a result, the proposed service model would be a useful and applicable service quality measurement model required by many organizations. Service company can set up self check service levels. Through these results, they can look for the ways to provide better services to customers. Service users can ensure the objectivity of business plan based upon SEM.

In the field of Internet of Things (IoT), smarter embedded devices offer functions via web services. The Quality-of-Service (QoS) prediction is a key measure that guarantees successful IoT service applications. In this study, a collaborative filtering method is presented for predicting response time of IoT service due to time-awareness characteristics of IoT. First, a calculation method of service response time similarity between different users is proposed. Then, to improve prediction accuracy, initial similarity values are adjusted and similar neighbors are selected by a similarity threshold. Finally, via a densified user-item matrix, service response time is predicted by collaborative filtering for current active users. The presented method is validated by experiments on a real web service QoS dataset. Experimental results indicate that better prediction accuracy can be achieved with the presented method.

This study investigated the use of community information and communication technologies in light of its dual visions (i.e., serving as an affordable Internet service provider and a community building tool). Surveying the randomly selected users of a community network (n = 213), this study examined the influence of the community features on service use compared to that of Internet features. The present study found that the respondents were using the service mainly for general Internet features, such as email and web access. More than two-thirds of the respondents did not recognize community contents as available service. Community features of the service were found as significant predictors of use only among people who were aware of community contents but not among people who were not. Nonetheless, there was no difference in the amount of use between the two groups, indicating that the awareness of community contents itself did not increase use. Findings suggest that the service providers did not fully communicate the community aspect of the service with the users although the very aspect distinguishes the service from other Internet services.

This study aimed to identify whether or not four service situations varying according to positive and negative combinations of physical evidence and functional service influence store image and purchase behavioral intentions of customers at bulgogi restaurants. The video-scenario technique was used for the study. Data were analyzed with the SPSS (Window 19.0) package using frequency analysis, one-way ANOVA, 2 by 2 factorial ANOVA, exploratory factor analysis, and multiple regression analysis to confirm the hypotheses. The combined effect of functional service and physical evidence influenced store image and purchase intention. In terms of seperate effect of physical evidence and functional service, the effect of employee service on store image was more powerful than that of physical evidence, even though the effect differed depending on the situation. Purchase intention was only influenced by functional service quality from employees under the four different scenarios. Thus, when opening a Korean restaurant, proper management of tangible evidence suitable to service, and the prices expected from local customers should be determined. Additionally, extremely high or low levels of physical evidence management should be avoided.
