In this paper, we carry out a cyber group consultation by means of the video-based education system, and verify the effects. For the verification of this study, two assumptions were set up. These assumptions were inspected by selecting 45 students of D elementary school located in a big city, and coming up with a test utilizing one of video-based education systems. Following up, a self-respect test form and a questionnaire were made to verify of the group consultation to the video-based education system, and by analyzing the test form and the questionnaire, the conclusion of this study was finally drawn. The conclusion gained through the process adove is as follows: It turned out that real-time video-based cyber group consultation promoted self-respect and enthusiastic participation of consulters as well as formed emotinal stability and a close affinity between the consultant and the consulter through active interaction. The results of this video-based education system operation will be helpful to broaden the area of elementary school cyber group consultation. Further, it is thought that it will contribute to the basic investigation to verify the educational effects of Multi-point imaging system in the run-up to the operation of full-scale real-time video-based education systems.

The purpose of this study is to increase efficiency and accuracy in operation of CPR(Cardiopulmonary Resuscitation) through comparing accuracy in CPR between group with verbal order and group with non-verbal order given carrying out CPR. This study performed convenience sampling targeting 62 students(31 people for group with non-verbal order, 31 people for group with verbal order) at university where is located in G Province. Survey period was carried out from October 7, 2010 to October 21. Analytical method was made by using SPSS WIN(Version 12.0). As a result of research, the group with non-verbal order was indicated to be higher in accuracy of CPR on artificial respiration and chest compression in several spheres than the group with verbal order. Based on this, the non-verbal order method needs to try to be applied to performing education and skills of CPR in the future. And, even a continuous research is needed on effectiveness between verbal order method and non-verbal order method in an emergency situation.

This study aimed to analyse the effects of a self-regulation group counselling program on self-esteem and self-control in adolescents on probation. In respect to sub-areas of the effects the self-regulation group counselling program had on self-esteem in adolescents, there were statistically significant differences in general self-esteem, social self-esteem and family self-esteem. Also, there were statistically significant differences in all the areas including impulse control and emotional control as sub-areas of self-control. Such results experimentally showed that the self-regulation group counselling program had a significant effect on self-esteem and self-control in adolescents on probation. Therefore, it is expected that the probability of repeating their crimes will decrease greatly if the subjects have self-esteem and self-control enhanced through the group counselling program. It is suggested further studies on the self-regulation group counselling program and its practical use are needed to enhance self-esteem and self-control in adolescents on probation.

This study aimed to find the related factors of nursing students' self-efficacy(including general self-efficacy and social self-efficacy), self-leadership and academic performance. Collected data were analyzed using SPSS 19.0. The general self-efficacy scores of the subjects in who're admitted according to aptitude, higher school grades, extroverts, and higher leadership were significantly higher than those who weren't. The social self-efficacy scores were significantly higher in younger ages, extroverts and higher leadership. Self-leadership was higher in those who're admitted according to aptitude. Academic performance was significantly higher in the females and higher school grades. Social self-efficacy was positively correlated with self-leadership, and negatively with academic performance. Explanation rate of sex, general self-efficacy and social self-efficacy on academic performance was 10.5%. These results can be applied as a basis for developing guidelines of nursing students' self-efficacy, self-leadership and academic performance after repeated studies.

The genetic diversity and population structures of fourteen Carex okamotoi (Cyperaceae) populations in Korea were determined using genetic variation at 25 allozyme loci. The Carex okamotoi species is native to Korea. It is endemic to three mountains (Mt. Taeback, Mt. Sobak, and Mt. Noreong) where it is found at 700~1,500 m above sea level. The percentage of polymorphic loci was 40.0%. Genetic diversity at the species level and at the population level was low ($H_{ES}$=0.106; $H_{EP}$=0.094), and the extent of the population divergence was relatively low ($G_{ST}$=0.082). Measurement of deviation from random mating ($F_{IS}$) within the 14 populations was 0.238. An indirect estimate of the number of migrants per generation was 2.78 (Nm=2.78). Analysis of fixation indices revealed a substantial heterozygosity deficiency in some populations and at some loci. Mean genetic identity between populations was 0.986.

The wisdom contents consists of an ordinary person's ideas and experience. The Wisdom Market [1] is an online business model where wisdom contents are traded. Thus, the general public could do business activities in the Wisdom Market at ease. As the wisdom contents are themselves the thought of persons, there exists many similar or duplicated contents. Existing copyright protection schemes mainly focus on the primary author's right. Thus, it's not appropriate for protecting the contents of Collective Intelligence that requires to protect the rights of collaborators. There should exist a new method to be dynamic capable of combining and deleting rights of select collaborators. In this study, we propose collective copyright authentication scheme suitable for the contents of Collective Intelligence. The proposed scheme consists of collective copyright registration, addition and verification protocols. It could be applied to various business models that require to combine multiple rights of similar contents or to represent multiple authorships on the same contents.
