Along with increasing of its subscribers and traffic for high-speed LTE service, it is widely expected to bring about the 2nd data explosion and results in any inconvenience of users. This paper proposes a smart traffic management scheme and its system design based on user's participating with the mobile application, in order to provide a fast and stable service for end users as well as to resolve the network overhead with increasing traffic. By making use of a time shift by users who want to reduce data usage amount and communication cost, the proposed scheme tries to reduce the peak traffic by shifting the delay-tolerant services, such as file sharing and software download, into the other time line. It also reduces the high volumed video traffics by transforming them into a user customized one. In addition, we suggest a mechanism to select video size and service time, then proposes an overall system design and its user service scenarios.

Purpose: The purpose of the study was to identify differences in physiological· psychological environmental behavioral characteristics between obese and control children participating in a health camp and to identify the factors related to childhood obesity. Methods: Two hundred eighty seven children aged 6 to 12 years were recruited from a health camp for elementary students in D city, Korea. Data collection was done on November 28 and 29, 2009. Anthropometric measurements, blood tests, and self-report surveys were conducted. Chi-square test, independent t-test, ANCOVA, and multiple logistic regression were performed using PASW statistics 18.0. Results: Obese children had adverse conditions for both physiological and psychological characteristics. In terms of environmental and behavioral characteristics, high maternal BMI and more than two hours of TV watching were significantly associated with high risk of childhood obesity (OR=1.11, 95% CI=1.02-1.21; OR=2.05, 95% CI=1.23-3.41). Conclusion: Through a multi-factorial approach, the current study identified the differences between obese and control children participating in a health camp and risk factors of childhood obesity. These findings provide preliminary data and perspectives on intervention research for prevention and management of childhood obesity.

This New-Town Project has been proposed to improve the environments of deprived residential areas. This paper investigates the distribution levels of the participating parties' monetary surpluses from New-Town Projects through a case study and tentatively suggests political issues and measures. The methodology followed includes a thorough survey of the precedent theories, including a literature review concerning issues and tasks that have been raised since the development was initiated. A general assessment of the complete project is also provided with a broad perspective of the background settings. Secondly, the case study of Gil-Eum will be the focus for identifying the mechanism for the project's profit distribution levels, then for constructing a set of measuring procedures according to the stages of the project and the participating parties. This set of procedures that has been drawn out from recognizing the system, is applied to the target project and measures the amount of profit gained from each stage of the development. This also aids in collating information about the procedural arguments concerning the financial gains of the operations that have been provided. This project falls under the 'Urban and Residential Environment Improvement Act', and based on the results of each stage, the measurement of the profits of the participating parties is analyzed.

This study examines the effects of health-promoting behaviors of grandmothers participating in their infant grandchildren's nurture and provides data for enhancing the quality of their lives. The sample included 218 consenting subjects who understood the purpose of the study. These subjects resided in three cities in Jeollanam-do, Korea, and were grandmothers entrusted by their adult children with a considerable amount of nurturing for their preschool-aged grandchildren under the age of six. First, the subjects scored an average of 3.05 for health-promoting behaviors and 2.42 for entrapment. Second, the entrapment measurement based on general characteristics showed a higher level of entrapment for those with better health, a lower education level, no religion, male grandchildren to nurture, and unsatisfactory compensation. Third, health-promoting behaviors and entrapment (r=-.304) were negatively correlated. Fourth, the analysis results for effects of health-promoting behaviors of grandmothers on entrapment based on general characteristics of grandmothers as a control variable reveal a significant effect of health-promoting behaviors on entrapment. In other words, the greater the employment of health-promoting behaviors, the less likely the entrapment was to be perceived. Fifth, the results for effects of subcriteria for health-promoting behaviors on entrapment reveal a decrease in entrapment when the subjects engaged in an appropriate level of physical activity with a relaxed state of mind. These results suggest that health-promoting behaviors of grandmothers participating in their infant grandchildren's nurture are likely to influence entrapment and thus that grandmothers should make efforts to actively engage in health-promoting behaviors to reduce any maladaptive effects on nurturing. Social support and related programs should be fostered to enable grandmothers to better practice health-promoting behaviors while nurturing their grandchildren.

This paper closely examines the relation between ‘how the local residents' involvement in a tourist industry and their perception of tourist development have an influence on tourism' and also 'how the understanding of a tourist effect has an influence on the local residents' participating intention in the tourist policy'. The local residents' involvement in the tourist industry was influenced by economical and socio-cultural factors among the influencing perceptions on local festivals, but, statistically, was not influenced by an environmental factor. The local residents' perception of tourist development has influenced on each local festival, and for the rate of influence, the environmental factor was the highest, and in the next order, the residents' intention to participate in tourist policy, the socio-cultural factor, and the economical factor followed. In the relation between local residents' perception of tourist influence and their participating intention, only the factor of socio-culture had a plus(+) influence on the participating intention in the tourist policy. It is expected that this result will be different from the tourist influence of tourist development. Therefore, a study of the perception on the influence of tourist development will be required in the future.
