This research aims to analyze the changes in participants' capacity (problem-solving ability and self-leadership), humanity (self-efficacy), and global network (intercultural sensitivity) as performance indicators and the 'effectiveness of personal characteristics' of the World Friends IT Volunteers program. To do this, the study conducted a pre-test and a post-test on 364 participants of the World Friends IT Volunteers program. The collected data is investigated through ANCOVA using covariates, driven from the prerest results. The results of this study represent that meaningful improvements have been identified in problem-solving ability, self-leadership and intercultural sensitivity since the operation of the program. Regarding the personal characteristics, performance in the female group improved more than the male group in terms of intercultural sensitivity, whereas the male group showed better performance on self-efficacy than the female group. In addition, the group with a high level of English proficiency showed more progress on intercultural sensitivity and self-leadership than the English-beginner group. Besides, the group who had an experience of short-term stay overseas showed moderate improvement on problem-solving ability and intercultural sensitivity when compared to other groups. The group who had lived overseas for a long-term showed better indicators on intercultural sensitivity. Also, self-efficacy of the leader group was more noticeable than that of the member group.

Background: The purpose of this study was to confirm the major motivation for and self-efficacy of career decisions among dental hygiene students and to analyze differences in career decision self-efficacy according to the major motivation. Methods: An online survey was conducted among 194 dental hygiene students. To investigate career decision self-efficacy, 18 questions were posed, including 5 questions on future planning, 4 questions on self-evaluation, 4 questions on job information collection, 3 questions on goal setting, and 2 questions on problem solving. The survey was conducted using a 5-point scale. Results: The motives for choosing a major were a high employment rate (68.6%), a desire to become a professional (36.1%), according to aptitude (27.8%), recommendations by others (26.3%), and according to grades (12.9%). The career decision self-efficacy of the study participants was in the order of self-evaluation factors (3.75 points), problem solving factors a (3.62 points), job information collection factors (3.59 points), future planning factors (3.46 points), goal setting factors (3.44 points) score was high. The career decision self-efficacy scores were higher when the major motivation was "because I want to become a professional" and "because I think I have an aptitude for it." Conclusion: It is necessary to give students who wish to major in dental hygiene an opportunity to consider whether they have an aptitude for it by providing information on not only major subjects but also the duties and roles of dental hygienists. In addition, it is necessary to develop a career education program to help dental hygiene students set their career goals.

This study investigates the change in two theoretical constructs, attitudes toward mathematics and mathematics self-efficacy, among college students involved in a learning community model. The case of this study was a developmental mathematics class offered at a historically black college located in the southeastern United States. Subjects included 31 students enrolled in an introductory mathematics course, some of whom participated in a learning community (treatment group). The participants completed mathematics attitudes and mathematics efficacy instruments twice: at the beginning of the semester and again at the end. Data was analyzed using descriptive statistics and a non-parametric statistic. The results showed that students' attitudes toward mathematics and mathematics self-efficacy are strongly correlated; the mathematical problem-solving efficacy changed significantly over time and it is significantly higher in the treatment group than in the control group; and the treatment group produced better outcomes. These findings indicate that a learning community model can increase students' mathematics self-efficacy beliefs. It is recommended that mathematics self-efficacy and attitudes toward mathematics be measured over an extended period of time when a learning community is implemented.

In this paper, we consider a network optimization problem arising from the deployment of BcN access network. BcN convergence services requires that access networks satisfy QoS meausres. BcN services have two types of traffics : stream traffic and elastic traffic. Stream traffic uses blocking probability as a QoS measure, while elastic traffic uses delay factor as a QoS measure. Incorporating the QoS requirements, we formulate the problem as a nonlinear mixed-integer Programming model. The Proposed model seeks to find a minimum cost dimensioning solution, while satisfying the QoS requirement. We propose two local search heuristic algorithms for solving the problem, and develop a network design system that implements the developed heuristic algorithms. We demonstrate the computational efficacy of the proposed algorithm by solving a realistic network design problem.

From the assumption that an individual's working memory capacity is limited, the cognitive load theory is concerned with providing adequate instructional design so as to avoid overloading the learner's working memory. Based on the cognitive load theory, this study aimed to provide implications for effective problem-based collaborative teaching and learning design by analyzing the level of middle school students' cognitive load which is perceived according to the problem types(short answer type, narrative type, project) in the process of collaborative problem solving in middle school function part. To do this, this study analyzed whether there is a relevant difference in the level of cognitive load for the problem type according to the math achievement level and gender in the process of cooperative problem solving. As a result, there was a relevant difference in the task burden and task difficulty perceived according to the types of problems in both first and second graders in middle schools students. and there was no significant difference in the cognitive effort. In addition, the efficacy of task performance differed between first and second graders. The significance of this study is as follows: in the process of collaborative problem solving learning, which is most frequently used in school classrooms, it examined students' cognitive load according to problem types in various aspects of grade, achievement level, and gender.
