The main purpose of this research is to introduce PsyCap(Positive Psychological Capital) and new leadership helping ordinary people to create positive thinking and leading to social integration in South Korea. Additionally, by looking at conventional leadership theories and by applying the PsyCap to leadership based on causal loop analysis, this study is to seek new approach which political leader is able to communicate with the people and can help the people to build positive mine. Throughout this study, there are several important implications how political leader can lead to social integration and stable political development in South Korea. In particular, when political leader encourage the people to have confidence to take on and put in the necessary effort to succeed at challenging tasks, when political leader make the people a positive attribution (optimism) about succeeding now and in the future, when political leader help the people to persevere toward goals and redirection paths to goals (hope) in order to succeed, and when political leader make the people beset by problems and adversity environment to overcome these concerns, it can be expected political leader to build social integration and the people to create positive thinking which has been emphasized by political leader in South Korea. Finally, 21st century has required new political leadership that the people are able to make positive psychological capital composed by optimism, hope, confidence, and resilience.

The purpose of this study is to help to improve the method of math teaching by analysing how learner-centered teaching method offsets mathematical creativity and mathematical disposition. For this purpose, research questions are established as follows; (1) Mathematical creativity between open-ended learning activity approach(OLAA) and general classroom-based instruction(GCI) shows any difference? (2) Mathematical disposition between OLAA and GCI shows any difference? The results obtained through this study were as follows: (1) There was significant difference between OLAA group and CCI group in mathematical creativity. This means that open-ended learning activity approach was generally more effective in improving mathematical creativity than general classroom-based instruction. (2) There was no significant difference between OLAA group and GCI group in mathematical disposition. But the average scores of mathematical disposition except mathematical confidence improved a little. So we can say that open-ended learning activity approach brought an positive influence on students' mathematical disposition. The results obtained in this study suggest that the OLAA can be used to cultivate the children's mathematical creativity and disposition. Therefore, I suggest that teachers should use the OLAA to improve the children's mathematical creativity and disposition.

In order to improve the performance of analysis, it is important to consider the nonlinearity in power system. The Carleman embedding technique (linearization procedure) provides an effective approach in reduction of nonlinear systems. In the approach, a group of differential equations in which the state variables are formed by the original state variables and the vector monomials one can build with products of positive integer powers of them, is constructed. In traditional Carleman linearization technique, the tensor matrix is truncated to form a square matrix, and then regular linear system theory is used to solve the truncated system directly. However, it is found that part of nonlinear information is neglected when truncating the Carleman model. This paper proposes a new approach to solve the problem, by combining the Poincar$\acute{e}$ transformation with the Carleman linearization. Case studies are presented to verify the proposed method. Modal analysis shows that, with traditional Carleman linearization, the calculated contribution factors are not symmetrical, while such problems are avoided in the improved approach.

The purpose of this study was to verify the effects of the Orff Approach to music education programs on singing ability, the ability to play musical instruments, physical expression ability, musical improvisation ability as well as overall musical expressiveness in 5 year old children. The test subjects for this study consisted of fifty-eight children. They were arbitrarily assigned to the experimental group of 31 children and the control group of 27 children. The experimental group was engaged using the Orff music education program for a total of 16 sessions, while the control group conducted music activities according to the annual music education plan of M kindergarten. The main results of this study were as follows : The Orff Approach to music education program was effective in improving abilities in the sub-factors of the four kinds of musical expression ability (singing, playing musical instruments, physical expression and musical improvisation) as well as overall musical expressive abilities. These results indicate that the Orff Approach to music education programs can create positive effects in the developing musical expressiveness of young children.

This study develops an effective method for sentiment analysis of user-generated content on drug review websites, which has not been investigated extensively compared to other general domains, such as product reviews. A clause-level sentiment analysis algorithm is developed since each sentence can contain multiple clauses discussing multiple aspects of a drug. The method adopts a pure linguistic approach of computing the sentiment orientation (positive, negative, or neutral) of a clause from the prior sentiment scores assigned to words, taking into consideration the grammatical relations and semantic annotation (such as disorder terms) of words in the clause. Experiment results with 2,700 clauses show the effectiveness of the proposed approach, and it performed significantly better than the baseline approaches using a machine learning approach. Various challenging issues were identified and discussed through error analysis. The application of the proposed sentiment analysis approach will be useful not only for patients, but also for drug makers and clinicians to obtain valuable summaries of public opinion. Since sentiment analysis is domain specific, domain knowledge in drug reviews is incorporated into the sentiment analysis algorithm to provide more accurate analysis. In particular, MetaMap is used to map various health and medical terms (such as disease and drug names) to semantic types in the Unified Medical Language System (UMLS) Semantic Network.

Social networking services (SNSs) such as Twitter, MySpace, and Facebook have become progressively significant with its billions of users. Still, alongside this increase is an increase in security threats such as cross-site scripting (XSS) threat. Recently, a few approaches have been proposed to detect an XSS attack on SNSs. Due to the certain recent features of SNSs webpages such as JavaScript and AJAX, however, the existing approaches are not efficient in combating XSS attack on SNSs. In this paper, we propose a machine learning-based approach to detecting XSS attack on SNSs. In our approach, the detection of XSS attack is performed based on three features: URLs, webpage, and SNSs. A dataset is prepared by collecting 1,000 SNSs webpages and extracting the features from these webpages. Ten different machine learning classifiers are used on a prepared dataset to classify webpages into two categories: XSS or non-XSS. To validate the efficiency of the proposed approach, we evaluated and compared it with other existing approaches. The evaluation results show that our approach attains better performance in the SNS environment, recording the highest accuracy of 0.972 and lowest false positive rate of 0.87.

Objective : The purpose of this study is not only to examine the negative functions of alcohol, but also to examine the positive functions and look at it with a balanced perspective. Methods : We investigated the number of times the word "酒"(alcohol) appears in 《Hwangjenaegyeong》 and 《Gyeongakjeonseo》. The meaning of alcohol was divided into seven categories. The number of positive and negative functions of alcohol was counted and the ratio was calculated. Results : 1. In the 《Hwangjenaegyeong》, the word alcohol appears 23 times, of which 9 times has positive functions, 10 times has negative functions, and the remaining 4 times does not correspond anywhere. The ratio of positive functions is 39.13% and negative functions 43.48%. 2. In the 《Gyeongakjeonseo》, the word alcohol appears 1,487 times, of which 1,140 times (76.66%) has positive functions, and 327 times (21.99%) has negative functions. Conclusions : 1. In 《Hwangjenaegyeong》, the number of comments about positive and negative functions of alcohol is similar. 2. 《Gyeongakjeonseo》 has commented a lot about the positive functions of alcohol. However, it has more mentions to negative functions of alcohol except for those related to herbs and prescriptions (48 to 64 chapter). 3. It is somewhat unreasonable to judge the emphasis on the positive and negative function of alcohol according to the number of references to alcohol in oriental medicine classics. But in these books, we can find a balanced approach between the two sides, not a one-sided biased view. 4. From a curative point of view, it is desirable to know and to use the positive and negative functions of alcohol, and drink alcohol as appropriate control.

The purpose of this study was to show that yoga psychology aims to actualize the positive potentials in the depth of human mind with the perspective of body-emotion-mind-spirit integration. This approach is described in the context of modern positive psychology. For this purpose, the Self-realization of yoga psychology is discussed, which is to develop one's higher self as a center of psyche apart from one's psychological growth or maturation. An individual can experience positive emotions such as pleasure, joy, happiness and ecstasy through the typical yoga technique of concentration. Happiness is one of the main issues of positive psychology, but yoga psychology called it "ānanda" and divided it further into seven types. The positive emotions of positive psychology seem to be equivalent to positive states of mind in yoga psychology. But yoga regards calmness, tranquility, nonattachment and transcendence as the most valuable virtues for the full actualization of human potentials. From the perspective of yoga psychology, the tranquil state of mind is the wonderful fruit of long and arduous yoga practices. It is the calm and neutral state of mind which is free from all the turmoils of everyday life. Tranquility is beyond the scope of modern positive psychology's issues, but it offers some precious insights to them.
