This study was designed to contribute to the right development of children's physical strength and growth by making a comparative analysis of 6 graders' physical strength with the help of the 6 events of physical strength tests according to sex and trying to work out some relationship between obese children and normal ones. With this in mind, the subjects were 400 elementary students, obese and normal, who reside in Seoul. The results were made by means of the average records and standard deviation test of 6-event physical strength tests per sex and group. The conclusions were as follows; 1. The normal children's average score was better than those of their counterparts, showing a significant difference in the 6-event of physical strength tests. 2. There was a little difference per sex. And there was a significant static interrelations in 4 events except a 100 m race and a standing broad jump when the subjects do well in the two afore-mentioned events. All the other groups minus female normal one show a low interrelations in such events as a 100 m race, a chin-up, and hanging down from the horizontal bar. 3. The obese group was inferior to the normal one regardless of sex. In terms of the physical interrelations, there was no difference among the three groups minus the female normal one.

The purpose of this parer is to examine the specifies of Institutional Arbitration and Ad Hoc Arbitration. The court prefers the institutional award in the enforcement rather than the award issued under the name of arbitrators alone. For example, the ICC Court of Arbitration scrutinizes awards for completeness, adherence to the ICC Rules and internal consistency, which since the court assurance for enforcement. In terms of arbitration costs, for which the ad hoc arbitration is considered to have comparative advantages, the institutional arbitration may not be more expensive than ad hoc arbitration, as in most commercial case, the administrative fees are insignificant. This paper suggests the standard or model arbitration clauses in institutional and ad hoc arbitrations. These Clauses contains the minimum elements necessary to render the arbitration agreement enforceable and effective. So both parties may add the specific contents such as the number of arbitrator, the place of arbitration and the language. Especially, in Ad Hoc Arbitration without designated set of rules, more clean clause for appointing arbitrators will be needed.

The purpose of this paper was to compare and analyze the elementary curriculum and textbook integration of social studies in Korea, USA, and England in terms of content integration and to make suggestions for the improvement of Korean social studies curriculum and textbooks. For this study, social studies curriculum and textbooks of three different countries were analyzed according to the three criteria: sequence, types and focus of integration. In this comparative study, five suggestions were made for the improvement of the Korean elementary social studies curriculum and textbooks. First, Korean social studies curriculum should have a subject focus at each grade level. Second, it is recommended that Korean social studies curriculum should present clear interrelations among geography, history, and civics at each grade level. Third, Korean social studies curriculum needs to have diverse criteria on which to select and organize themes. Fourth, Korean social studies textbooks need to have increased number of interdisciplinary large units. Fifth, it is necessary that the authors of Korean social studies textbooks integrate contents in consideration of students' life context in order to raise the relevance of the contents of history and geography.

The flow behavior of polymer melts within a slit die is an important consideration when designing a die geometry. The quality of the extruded polymer product can be determined through an evaluation of the flow homogeneity, wall shear rate and pressure drop across the central height of the die. However, mathematical formulations cannot fully determine the behavior of the flow due to the complex nature of fluid dynamics and the nonlinear physical properties of the polymer melts. This paper examines two slit die geometries in terms of outlet velocity uniformity, shear rate uniformity at the walls and pressure drop by using the licensed computational fluid dynamics package, Ansys POLYFLOW, based on the finite element method. The Carreau-Yasuda viscosity model was used for the rheological properties of the polypropylene. Comparative analysis of the simulation results will conclude that the modified die design performs better in all three aspects providing uniform exit velocity, uniform wall shear rates, and lower pressure drop.

This paper aims to develop a conceptual model of smart tourism destination competitiveness to provide implications in terms of smart tourism destination realization and smart tourism destination competitiveness development. A literature review on tourism destination competitiveness and smart tourism destination is performed. A conceptual model is suggested on the basis of the model of destination competitiveness developed by Crouch and Ritchie (1999). The suggested conceptual model integrates the traditional concepts of comparative advantages and competitive advantages, seven core resources and attractors, and five destination management factors. Smart technology is included as a new core resource and attractor in the model. This study is the first to comprehensively conceptualize smart tourism destination competitiveness. Moreover, this study has practical value in the sense that it focused on the convergence between smart technology and other factors.

Cool roofs are currently being emerged as one of important mechanism to save energy in relation to the building. This paper reviews worldwide experiences (USA, Japan and EU etc) for the potential benefits cool roofs offer in relation to building energy saving for comparison purposes. It is confirmed that there is a significant potential to the energy saving by introducing the cool roof in a Korean climate because of similarity in terms of HDD (Heating Degree Day) and CDD (Cooling Degree Day) as those countries reviewed. Such a comparative study highlights that the type of measurements performed and the quantitative parameters reported from the countries should be standardized in Korean context in order to implement further comparable experiments for scientifically sound investigations. It is anticipated that this research output could be used as a valuable reference in implementing a Nation-wide cool roofing strategy in the central and local governments since a suitable technical, more objective direction has been proposed based on the measured, fully quantitative performance of the involved components of a cool roof system in the global context. From this critical review, a very important step has been made concerning the practicality of cool roof in Korean context. Ultimately, the suggestion in this paper will greatly contribute to opening new possibilities for introducing cool roof in this country, proposed as an initial aim of this paper.
