Purpose: This study was designed to construct a structural model explaining depression in university students. Methods: Data were collected from 1,640 university students by questionnaire, and analyzed using AMOS 5.0 to test the hypothetical model. Results: Fitness statistics for the modified model were GFI=.93, AGFI=.89, NFI=.91, and RMSEA=.081. All the 12 paths in the modified model proved to be statistically significant. Depression of university students accounted for 52% of the covariance by the factors. The factor that had the most influence on depression was individual vulnerability, and followed by sequence order, stress, social support, coping, and self-efficacy. Depression was influenced directly by individual vulnerability, stress, social support, and coping, and indirectly by individual vulnerability, stress, social support, and self-efficacy. Conclusion: A screening and management system for the high risk group is needed to effectively prevent depression and reduce rate of depression in university students. Detailed support programs which specifically deal with prevailing stressors should be developed to effectively reduce the harmful effects of individual vulnerability and stress. It is anticipated that the model constructed in this study could be utilized as a reference in developing various strategies to prevent and intervene depression in university students.

This research aims at finding out situation on purchasing clothes for kids, size recognition and fitting to provide basic data in order to establish standard sizes for kids' clothes. A survey was conducted to 360 mothers who have children ranging from first to third grade in elementary school on clothes purchasing method, wearing situation, criteria in deciding size and fitting preference. In terms of data analysis, frequency, percentage, mean, $X^2$-test, ANOVA and Duncan-test were used via SPSS PC program. The result is as follows; 1. While the recognition on brand was high, the recognition on body size was low: as a result, it is believed that it would be effective to mark the weight along with the brand. 2. Many times, they would select one or two size bigger on all items and they would go for a regular or one that fits as far as filling is concerned showing that it is different from adult clothes. 3. As far as obese kids, they would choose based on the diameter, so the diameter item is right but they are too long in general. The length question should be given special attention when manufacturing clothes for obese kids.

Purpose: The purpose of this study is to identify health-related factors, especially for the elderly who are subject to visiting health care at vulnerable populations. Methods: Tools were Guide to Community Integrated Health Promotion Project 2016, Visit Health Care Health Interview Survey, measures of physical function, motor skills, composite mobility, BMI, and subjective fitness levels. Depression was measured with the Short Results: Older elders living alone were more vulnerable than those with living others. Elders with less education showed greater weakness but the difference was not significant. Average scores for frailty were 2.21 (healthy group), 7.66 (high-risk group) and 15.69 (frail group). Scores based on weakness level differed significantly with the exception of nutrition. Nine out of 10 elders in disadvantaged areas were in the frail group or at high risk. Conclusion: Results support the goal to maintain/improve physical/mental functions through individual management of high-risk/frail older adults at risk of becoming infirm. It is imperative to implement a public health care delivery system to ensure programs are operated effectively and personalized.

Existing exercise management systems provided exercise information to the user. However, there is a problem that the accuracy is low due to the absence of an algorithm for analyzing the user's body information and providing information. In this paper, BMI(Body Mass Index) and BMR(Basal Metabolic Rate) values are analyzed to analyze user's body information. It also recommends exercise intensity and momentum to the user and graphs the history of the exercise device that the user has used. Through this, it is considered that the information corresponding to the user's body can be provided and the exercise management can be carried out.

International arbitration is an increasingly popular means of alternative dispute resolution for cross-border commercial transactions. The primary advantage of international arbitration over court litigation is enforceability. An international arbitration award is enforceable in most countries in the world. Especially, statistics indicate of ASEAN such as Malaysia and Singapore that the vast majority of defeated companies comply with the terms of international arbitral awards against them or settle soon after the award is rendered. Unlike Malaysia and Singapore, in Indonesia, there are several grounds for refusal of enforcement of an award including where both the nature of the dispute and the agreement to arbitrate do not meet the requirements set out in the Arbitration Law. Because Indonesia does not acknowledge decisions of foreign courts, theoretically they could enforce an international arbitral award which was set aside by the court in the seat of arbitration. This paper introduces the legal system and cases of recognition and enforcement of foreign arbitration awards in ASEAN, especially Malaysia, Singapore, and Indonesia. Secondly, by comparing their law and cases, the paper emphasized the international suitability and global fitness in involved in recognition and enforcement of foreign arbitration awards.

In order to improve the performance of relational databases, one has to reduce the number of disk accesses necessary to transfer data from disk to main memory. The paper proposes to reduce the number of disk I/O accesses by vertically partitioning relation into fragments and allowing attribute replication to fragments if necessary. When zero-one integer programming model is solved by the branch-and-bound method, it requires much computing time to solve a large sized problem. Therefore, heuristic solutions using genetic algorithm(GA) are presented. GA in this paper adapts a few ideas which are different from traditional genetic algorithms, for examples, a rank-based sharing fitness function, elitism and so on. In order to improve performance of GA, a set of optimal parameter levels is determined by the experiment and makes use of it. As relations are vertically partitioned allowing attribute replications and saved in disk, an attribute replicating vertical partition method by GA can attain less access cost than non-attribute-replication one and require less computing time than the branch-and-bound method in large-sized problems. Also, it can acquire a good solution similar to the optimum solution in small-sized problem.

This paper presents the impact minimization of a biped robot by using genetic algorithm. In case we want to accomplish the designed plan under the special environments, a robot will be required to have walking capability and patterns with legs, which are in a similar manner as the gaits of insects, dogs and human beings. In order to walk more effectively, studies of mobile robot movement are needed. To generate optimal motion for a biped robot, we employ genetic algorithm. Genetic algorithm is searching for technology that can look for solution from the whole district, and it is possible to search optimal solution from a fitness function that needs not to solve differential equation. In this paper, we generate trajectories of gait and trunk motion by using genetic algorithm. Using genetic algorithm not only on gait trajectory but also on trunk motion trajectory, we can obtain the smoothly stable motion of robot that has the least impact during the walk. All of the suggested motions of biped robot are investigated by simulations and verified through the real implementation.
