In the internet broadcast, efficient and scalable mechanism of multicast is needed for the communication between groups. Furthermore, Optimization of the multicast tree is required to improve the performance of overlay multicast. This optimization is well-known as NP-complete. If a node in the tree has limited out-degree, a user who wants to join the group has to find parent user who has already joined. In this paper, the users who want to join the group need to setup their level using delay test from source node. And then new users can find candidate parent nodes effectively using ACK-SEND approach and take proper position by comparing level. The closer node of the user to root node should be located in lower level. Also, even if a barrier is caused, fast recovery will be guaranteed using ACK-SEND approach. Through this, the newcomer node can fine their location in the multicast tree and join the group fast and effectively.

This study aims to explore the characteristics of environmental catalysts which have affected the development of music giftedness of the disadvantaged students. For this purpose, this study deals with nineteen disadvantaged gifted in music and examines their self-evaluation test, personal statement, and interview. Based on Gagn$\acute{e}$'s environmental catalysts of differentiated model of giftedness and talent(DMGT), the analysis of the interviews conveys the milieu of the disadvantaged gifted hardly exerts positive influences on their musical activities and studies. While concerning music and supporting their children financially and emotionally, parents unintentionally tend to exert negative influences on their children for their misapprehension of giftedness and incompetent advice. On the whole, the disadvantaged gifted hardly admit their teachers as experts in music. In relation to provisions, most students participate in extra school and local program and none of them participates in music gifted program. They are not satisfied with the quality in education. Despite the importance of the events such as crystallizing experience, award-winning, and performance, most students don't have enough events for inspiring their giftedness. As a conclusion, this study gives a proposition for a strategy to improve the environmental catalysts for the disadvantaged gifted in many different ways: the improvement of social recognition, the enhancement of parent consulting and teachers training programs, and the development and diffusions of more qualified gifted programs and so on.

The purpose of this study is to investigate the perception of the mothers of science gifted in respect to giftedness compared to the "Scale for Rating the Behavioral Characteristics of Superior Students-R(SRBCSS-R)". For that, a survey of 18 mothers of elementary school science gifted and 32 mothers of middle school science gifted was conducted in relation to giftedness. The words and frame of this survey were analyzed using the Semantic Network Analysis. The results are as follows : The mothers of Elementary school science gifted perception were found to have a connected giftedness with reading, science, making something, etc.. On the other hand, the mothers of middle school science gifted perception were found to have a connected giftedness with problem, solving problem, mathematics, etc. in words analysis. The mothers of Elementary school science gifted have a strong connection with category on creativity, motivation, etc.. On the other hand, the mothers of middle school science gifted were more inclined towards the category on learning, motivation, etc. in frame analysis. That is to say, the mothers of science gifted are perceptive about giftedness respect to some elements as the "Scale for Rating the Behavioral Characteristics of Superior Students-R" on the giftedness. Therefore, a correct understanding about giftedness in respect to the mothers of science gifted is required and parent education is needed for appropriate science gifted education.

The study aims to gain information for developing educational content to support LPSMBs (low-performing students with multicultural backgrounds) in elementary and middle schools. The procedure involved surveying students about their personal characteristics, attitudes related to learning, and learning environment. I analyzed responses from 1,147 students from 200 elementary schools and 3,760 students from 320 middle schools who were LPSMBs and NPSMBs (normally performing students with multicultural backgrounds). LPSMBs in both elementary and middle school showed statistically significant lower scores on most questionnaires related to learning and learning environment than NPSMBs. LPSMBs in elementary schools showed higher scores on teachers' learning support, LPSMBs in middle school showed higher scores on classmates' learning support. LPSMBs born in foreign countries need to be given opportunities to learn Korean as well as their father's and mother's culture. I give suggestions for how to support LPSMBs' learning and learning environment based on the survey results.

The purpose of this study was to investigate high school students' learning style, perception of types of laboratory instruction, and the relationship between the learning style and preferred type of laboratory instruction. The participants of this study were 19 female high school students, from Incheon in Korea, who showed outstanding science grades. Dunn et al's revised Learning Styles Inventory (1997) was used for testing students' learning style. The students were asked to choose preferred and not preferred types of experiments and describe the reason of the choices after implementation of 4 types of experiments: verification, discovery, explorator, and investigation laboratory instructions. The findings of this study were as follows: Firstly, the students had a certain common learning style irrelevant to their personal characteristics, i. e; they showed high (self, teacher, parents) motivation and structure stimuli that was common in Korean students. Second, outstanding students prefer unstructured and open laboratory instructions. And those students were highly influenced by sociological and emotional stimuli. Third, students' learning style was related to their preferred type of laboratory instruction. Students preferring unstructured and open laboratory were influenced by sociological and emotional stimuli, while those preferring structured and closed laboratory were influenced by physiological stimuli.

The purpose of this paper is to examine learning motivational process models, based on Self-Determination Theory(SDT) in academic settings. I examined if SDT's assumptions would fit for Korean adolescents, using a learning motivation scale(LMS), Basic Needs-autonomy, competence, and relatedness-Satisfaction Scale(BNSS), academic grades and life-quality scales, and also tried to search for the adequate motivational process models for Korean adolescents through regression analysis and structural equation model analysis. The results of this study are as follows. Basic needs satisfaction influences positively on the development of self-determinative motivation, which influences positively on academic achievement. But academic achievement and self-determinative motivation doesn't always influence on subjective well-being positively. And Korean adolescents who study autonomously or achieve good grades, are not better in a dimension of subjective well-being than others. Basic needs satisfaction while growing is more important than any other variables to improve adolescents' autonomous motivation, academic achievement and subjective life qualities.

The purpose of this study is to examine the mobile phone service usage patterns of Korean teenagers and their motivation to use it, and to explore the relationships between the teenagers' social-psychological characteristics and their trails of mobile phone usage. After reviewing prior theoretical studios, three hypotheses regarding the research questions shown above were generated. Questionnaire study was conducted with 400 high school students in Busan and Ulsan metropolitan areas. They were to answer three categories of questions, such as frequencies of voice calls and text messaging services and the other mobile services, questions asking their social-psychological characteristics, and their motivations for using mobile phone services. Findings show that the teenagers more likely to tend to use voice calls when communicating family members. They tend to avoid those services with high rate of use as multimedia, game, and broadcasting services via mobile phones. The teenagers use mobile phone services for the similar purposes to conventional telephone uses. Therefore, the classical theories showing the alternative purposes or motivations to use conventional telephone usage, which divided the main purposes for phone uses in to two; work/instrumental and socializing/entertaining, proved to be reasonable. The cheap messaging services with texts are popular among the teenagers and are used for socializing/entertaining purposes rather than instrumental/functional purposes. In addition, the teenagers' social-psychological characteristicss are significantly associated with the amount of mobile phone uses. A characteristic of "individual-centeredness" is positively related with non-voice service uses, while "group-centeredness" explains heavy amount of using voice calls and text messaging services. Such characteristics as "immediacy," "directness," "innovativeness," and "other-direction" are positively associated with the frequencies and amounts of mobile phone uses, while "inner-direction" and "tradition-direction" are negatively correlated.

The purpose of this research is to propose a plan on migration policy based on features, through analyzing the migration adaption process and the farming life of the back-to-countryside population throughout the nation. For this, survey has been conducted to find out urban-to-rural migrants' motives and characteristics. The major reason for the migration was the household's financial condition, and the most of migration decisions were made by either one's spouse or parents. The migration fund was primarily spent in early agricultural activities and it was the neighbors who aided them the most whilst teaching them many farming techniques. Some government-supported policies are being highly demanded regarding the lower level of income (than urban life) and difficulties of raising cultivation funds; these two things are what migrants consider as the most inconvenient and suffering matters in farming life. Many surveyee have responded that they would constantly stay in the rural area and continue on their life as a farmer, giving a promising prospect for future farmland life. Based on these trends and features, development strategy regarding elaborate settlement plan of urban-to-rural migration is necessary.

While entrepreneurship is touted as an opportunity for women to exploit opportunities that are often not available in the traditional workplace, the rate of participation in entrepreneurship is lower for women than it is for men. What remains relatively unclear are the reasons that make this so. This regional study addresses this deficiency by examining two lines of thought related to entrepreneurial adoption: (1) the personal traits thought to contribute to entrepreneurship, and (2) the rational decision making processes that are believed to form a basis for entrepreneurial endeavors. My results find men and women to be different in both respects, with ambiguity tolerance, internal locus of control, perceived effectiveness of entrepreneurship, and having an entrepreneurial parent all positively predicting entrepreneurial intention for men. For women, perceived effectiveness of entrepreneurship and achievement motivation predict entrepreneurial intention. Women also rate the potential reward of entrepreneurship as significantly lower than do men, possibly because women entrepreneurs objectively face more obstacles than men with regard to obtaining financing and other stakeholder relations.
