This study explored the heterogeneous latent group on the influence of the learner's perceived math teaching method(instructor-centered, learner-centered) on math self-efficacy. In order to profile the characteristics of the detected latent group, the distribution of variables was confirmed, and multi-group analysis was conducted by SEM. According to the analysis results, two latent groups were detected, and the instructor-type group and the learner-type group were named. As a result of post-hoc analysis, the perception of instructor-centered classes and learner-centered classes, and the perception of math teaching ability were similar between the instructor-type and the learner-type group. But the instructor-type group had higher math self-efficacy, math interest, and math class engagement than the learner-type group. Also, in the instructor-type group, the effect of perception of math teaching ability on math self-efficacy and math class engagement was greater than that of the learner-type group. Whereas, in the learner-type group, the effect of math interest on math self-efficacy and math class engagement was greater than that of the instructor-type group. This study presented a new research method on the influence of math teaching methods on learners by applying the REBUS-PLS method.

The purpose of this study is to determine the error sources and effects of each error source in self-control assessment of young children. The self-control of 259 five-year-old children was assessed using the Self-Control Rating Scale(SCRS) developed by Kendall and Wilcox[1]. The evaluation results were analyzed using G study of generalizability theory. The results of G study shows that parents can be effective evaluators for the self-control assessment of young children. The strategies to reduce the effects of error are also discussed.

In this study, a form-finding method of tensegrity systems by using the force density method combined with the stiffness matrix method was presented. Numerous studies have been made on form-finding methods of the tensegrity systems. However, these methods are limited in the tensegrity systems with multiple null space of the equilibrium matrix. The proposed method can uniquely define a single integral feasible set of force densities for the structures. In order to draw maximum natural frequency that can lead a maximum stiffness of the tensegrity systems, a constrained maximization problem is formulated in the genetic algorithm. Several numerical examples are presented to prove dfficiency in searching for self-equilibrium congifurations of tensegrity systems with multiple self-stress states. A good performance of the proposed method has been shown in the results.

Form-Finding of tensegrity structures by eigenvalue problem is presented, In ardor to maintain the structures stable, "Form-Finding" should be performed. The types of analytical methods are known to solve this phenomenon: One is to use force density method, and the other is to apply so called, generalized inverse method. In this paper, new form finding methods are presented to obtain the self-equilibrium stress of the tensegrity structures. This method is based on the equilibrium equation of the all of the joint and the governing equation is formulated as eigonvalue problem. In order to verify this approach, numerical example(tensegrity structures) are compared with others calculated by previous methods. The solution by present method is shown identical results. Furthermore, the developed process to find the results is more efficient than previous approaches.

대부분의 발달장애를 돌보는 어머니의 양육경험 속에는 스트레스로 인한 부정적 정서 및 우울증을 포함하지만, 어떤 어머니들은 장애자녀로 인해 가족 및 사회적 친화력을 높이고 긍정적인 정서경험을 통해 자신 및 가족의 삶의 질을 향상시켜 나간다. 본 연구는 발달장애를 돌보는 중년기 어머니들의 양육경험과 우울증의 상관관계에 있어 어머니의 자기자비와 중년기의 신체 및 심리적 특성에 대한 자기이해가 어떠한 영향을 미치는가에 대해 탐색하고자 한다. 연구수행에 필요한 자료 수집을 서울, 경기를 포함한 전국에 사는 발달장애 중년기 어머니 700명을 대상으로 하며, 자료는 SPSS PC+ Ver 28을 활용하여 빈도분석과 주요 변수에 대한 기술통계를 실시하고, 변인 간 상관관계, 회귀분석을 실행한다. 본 연구의 의의는 발달장애인 자녀를 돌보는 어머니의 양육 스트레스를 줄이고 건강한 가족회복을 위해 어머니의 자존감을 향상시킬 수 있는 자기자비의 역할과 중년기에 대한 자기이해를 강화하도록 도울 수 있는 장애인 가족지원 정책 및 사회 서비스 개발에 기여하고자 한다.

The concept of self efficacy, originally theorized by Bandura, has been applied to a wide variety of fields including education, psychology, and business. There has been steady effort to develop relevant scales to operationalize and measure self efficacy. This article reports on the results from an analysis of Kurbanoglu's ILSES (Information Literacy Self-Efficacy Scale), the only reported such scale in the area of information literacy. Over 400 university students responded to the ILSES survey consisting of 40 items grouped in six categories. The main analysis used was factor analysis. The results show high degree of internal consistency of the items included. However, the factors derived from the study differ significantly from the factors in the original study. Overall, these factors seem to reflect the heuristic nature of students' information seeking and use patterns, favoring Internet resources and instant gratification.

The purpose of this study was to investigate the effect of career preparation program on self-esteem, self-efficacy related career decision-making and career development readiness in university students. The structured career development program was given in 124 participants, Sep.~Dec, 2014 in D city. SPSS/Win 18.0. was used. The 1.06 points were decreased in self-esteem(t=3.39, p=.00) than before. The 14.22 points, 17.36 points were increased in self-efficacy(t=-12.41, p=.00), and career development readiness(t=-13.85, p=.00) than before. It showed the program was effective. Three variables showed correlation with one another. We suggested this structured career preparation program would be applied and extended more in career development for the college students. And the follow-up studies about self esteem and relating factors will be needed.
