Objectives The purpose of this study is to investigate the relationship between physical activity and growth indices. Methods 5963 of 12 years old adolescents were participated in the 10th Korea Youth Risk Behavior Web-Based Survey (KYRBWS-V) project in 2014. These data was analyzed to show the relationship between physical activity and height, BMI. Results According to the Physical Activity guidelines, the mean height was higher in the each male and female group with 'moderate physical activity for at least 60 min ${\geq}7$ days/week', 'vigorous physical activity ${\geq}3$ days/week', and 'muscle-strengthening activity ${\geq}3$ days/week' compare to the group who did not. The mean BMI was lower in the male group of 'sitting for watching TV or computer, etc on a weekday < 3 hr/day' compare to group who did not. Conclusions These results showed that physical activity in adolescence is correlated to growth. Therefore, this research can be one of the reference data to show the proper physical activity is important in the growth.

Business transactional process is usually long running computation which requests services from multiple enterprises. Web Services Transaction specification (WS-TX) defines a protocol, WS-BusinessActivity which is specifically designed for such lengthy interaction and maintains overall consistency through compensation. However timely web services transaction is prone to compensate due to tasks' missing deadline. Therefore, this paper proposes a reservation-based protocol which is used to select providers who can provide resources promptly and deselect ones who may fail. And this selection happens during resource reservation phase and before real commitment. In this way, we achieve the goal of minimizing transactions' compensation. Finally, we design the framework architecture for the proposed protocol that is extended from WS-BusinessActivity.

Purpose: Level of reflective thinking of students are important factors in the area of nursing studies on web-based PBL. These factors were used as a component of learning strategies. One was to understand general recognition to web-based PBL and reaction to the use of reflective journal. The other was to investigate the level of reflective thinking was related to learning activity. Method: PBL was adopted for an online course titled 'Nursing Assessment and Intervention'. Twenty graduate students were evaluated from questionnaire, reflective journals, and individual assignments. Result: Web-based PBL was strong for self-directed learning, team activity, creative thinking, diversity of thinking, and diverse process of learning while hard time, lack of cooperation, uncertainty of outcome, and lack of time were considered as weakness. Reflective journal gave moderate help to learning activities. The learners' learning activities was the lowest in the middle level of reflective thinking. Conclusion: Generally, graduate students in college of nursing showed slightly positive attitude to PBL experience and slightly positive reaction to the learning effect of reflective journal. PBL was estimated to be valuable and meaningful. There was no relationship between the level of reflective thinking and learning activities.

As the interest in internet business increases, effective web site evaluation is in order. While web site evaluation is supposed to be based on feasible applicability and trust-worthy criteria. many researches on web site evaluation fails to rover the various business models and consider corporate-activity-related features. Besides, dealing with the limited aspects such as design and cognitive science is something to be desired on the previous researches. Therefore, This paper presents internet web site evaluation framework not only based on existing researches and analysis but also reflecting corporate strategies. The framework includes web sites contents, design, operation and management-related factors, and it is applied to companies to validate its applicability.

This study proposes a web presence readiness model based on pre-payment service functions and a post-payment service function both of which embrace the major concerns of customers in the online purchasing context. Based on the concept of customer utility from the product itself and instrumental utility, the research model suggests four antecedents including, Perceived Economic Benefits, Product Search Support Quality, e-Shopping Method Diversity, and Post-Payment Support Quality. We empirically examined a proposed research model using data collected from online rating company websites. Among the four antecedents, post payment support quality is found to be the most influential determinant of customer evaluation on e-commerce websites. Based on the empirical results, the current study proposes an alternate model of web presence readiness. The findings of this study may provide an insight to field practitioners designing commercial websites. The implications and future research directions are further discussed.

Many web-based learning systems have been developed and used widely. Most of the researches on web-based learning systems assume learners' active participation in the learning activity. However, learners do not always actively participate in the learning. This paper presents a novel self-regulated learning strategy to create a learning environment that encourages learner's active participation. We have derived sub-strategies that can be implemented as a web-based system. The derived sub-strategies have been implemented as an advanced web-base system and are verified by an empirical study.

When a designer creates a new web-based learning-teaching system, there are so many considerations to help learners' learning effect through effective interaction. First of all, web-based simulation is recommended to provide learners with effective and attractive learning environments in web. Efficient study design should be considered because well designed simulation-based contents provide continuous interest for learner. Until now many e-Learning systems provide web-based simulation using various technique. However, those contents require to be reorganized considering the level of accomplishment, learning styles. In this paper, I proposed a system that the learners can share simulation objects among other e-Learning systems using XML web service. By experimental result, the proposed system shows that is more efficient than the conventional system in the self-leading study activity and interactivity.

Purpose: This study aimed to develop a web-based cost management program for visiting nursing centers (CMP-VNC), using time-driven activity-based costing (TD-ABC), and to analyze effects of the program. Methods: The CMP-VNC was developed using the combined prototyping approach and system developing life cycle method following four stages: need analysis with comprehensive literature reviews and focus group interviews, design and development of program algorithm, evaluation of the developed program validity using experts and users group, and application and effects analysis. The non-equivalent control group pretest-posttest design was used to analyze the effects of the program. The program demonstration was conducted for four weeks with 60 visiting nurses in 35 visiting centers. Results: The web-based program was developed. It has five interfaces with basic and special functions using TD-ABC, namely, input, visiting nursing activity, visiting nursing activity cost, cost efficiency, and cost calculation report. The experimental group showed significantly higher cost perception and cost confidence than control group. Conclusion: We found that the CMP-VNC can be an effective tool to increase visiting nurses' competency of costing and enhance efficiencies of visiting nursing centers.

Media Contents Recommendation Web Service (service name 'mobodra') is a web service that analyzes media types and genre tastes for each user and recommends content accordingly. Users select some of the works randomly provided on the web when signing up for membership and analyze their tastes based on this. Based on this analysis, preferred content for each user is recommended. In this paper, we implement a content recommendation algorithm through item-based collaborative filtering. When the user's activity data or preference is re-examined, the above process is executed again to update the user's taste.

To better publish geographical information on the Web, it is important to capture how Web technologies are changing. For a recent decade, Semantic Web has been developed by incorporating ontologies into the current Web, with an aim to make computers understand rather than simply display. Ontology, an explicit specification of a conceptualization, and the Semantic Web grounded on the ontology, have the potential for effective sharing and appropriate retrieval of geographical information. This paper describes a Semantic Web Service over the mobile Web that can offer pertinent tourism information according to user contexts. To do this, a tourism ontology was formalized in the PARA(Place-Attraction-Resource-Activity) ontology model by organizing tourist places, tourist attractions, tourism resources, and activities. Locational relationships between tourist places were also included in the PARA ontology model to take into account the movements of tourists on a railway network. The XML(Extensible Markup Language) Web Service in the middle tier manages the client-side request for information retrieval and the corresponding server-side response from the data provider. The PARA ontology was integrated into the XML Web Service for the concept-based discovery of tourism information. The applicability of the proposed system was tested through a simulation experiment for Tokyo tourism.
