  • Efficient scheduling for software development is a major concern for software engineers. Industries simultaneously try to perform a variety of projects with the limited resources on schedule. A way to overcome the limitation of resources is sharing of the resources through the projects. This study discusses the matrix organization for software development. A scheduling for matrix organization is a special case of project management problem. The ultimate goal of scheduling problem in this study is to minimize the overall duration of the multiple projects. A genetic algorithm is presented to solve the scheduling problem of the matrix organization and is substantiated with numerical results.

  • The purpose of this study is to investigate the assessment expertise of Mathematics' teachers, focusing on the competence in designing assessment item development. In this present research, I analysed how the teachers' competence appears in designing assessment items development when they generated problems the given problem into a new one. To examine this assumption, the following research questions were posed and investigated in the present study : How do Pre-service and In-service Teachers in primary schools develop the assessment item when generating problems the given problems into new problems? The result from the case study of metamorphosing the given problem into a new problem teachers used similar patterns switching numbers or changing units in order to develop new problems. Also, teachers in primary schools tend to develop problems as commonly as in the mathematics workbooks. In-service teachers tend to have better skills developing assessment items, but there were quite much of variability between individuals.

  • Problem-Based Learning (PBL) is a student-centered pedagogy that integrates nursing knowledge, skills, and attitudes into clinical nursing practice. This pilot aims to apply a PBL module on preschoolers' growth and development in the nursing curriculum. This quantitative study was performed to develop a PBL module following Dick and Carye's program development process (planning, development, application, and evaluation phases), and to evaluate its effects using structured questionnaires among sophomore nursing students. These students formed teams of four or five people each and spent 40 minutes participating in the PBL module. Data were analyzed using descriptive statistics, t-tests, and content analysis. Metacognition level increased significantly. There was no significant difference in team efficacy between pre-test and post-test. Post-test learning satisfaction was high. Students reported obtaining knowledge and problem-solving ability with respect to preschoolers' growth and development and were satisfied with teamwork. This finding offers fundamental knowledge concerning the application of a PBL module in nursing curricula.

  • Purpose: The purpose of this study was to verify the educational effectiveness of the Objective structured clinical examination (OSCE) module development activities on nursing students in the areas of performance skill, knowledge, self-directed learning readiness, and problem solving ability for medication skill. Methods: This study was a nonequivalent control group non-synchronized post-test design. The subjects (N=47), who agreed to participate in this study, were assigned to either the experimental (n=24) or control group (n=23). The experimental group was trained with OSCE module development activities for four days. The control group was trained with a traditional demonstration and practice class for the same amount of time as the experimental group. Medication performance skill and knowledge tests and surveys were done to measure self-directed learning readiness, and learning satisfaction after the experimental treatments. Results: The experimental group which participated in the OSCE module development activities showed significantly higher performance skill, self-directed learning readiness, and problem solving ability for skin test and insulin medication than that of the control group of traditional education. Conclusion: It is recommended to use the OSCE module development activities for nursing students in nursing education-learning in order to improve nursing skills.

  • Super In Plane Switching (S-IPS) technology is applied for large TFT-LCD panels used in TV applications. It has a lot of advantages in comparison to the alternative, VA technology. S-IPS shows excellent viewing angle properties and fast response time between intermediate gray levels. If the performance parameters which describe the actual visual performance are considered, S-IPS is much more $advantageous.^{1)}$ However, it shows relatively low contrast ratio in diagonal direction compared to viewing angle characteristic in upper/down direction in S-IPS. In order to compensate the relatively low diagonal contrast ratio, Super-IPS applying for optical film developed, but Super-IPS still has the problem of color shift in black $pattern.^{2)}$ So we improved this problem by developing Enhanced Super-IPS.

  • In this study of the influence of marital conflict and of children's temperament and emotion regulation on problem behavior, 194 mothers of 3- to 5-year-old children responded to the O'Leary- Poter Scale(1980), the Emotionality, Activity and Shyness scale(Buss & Plomin, 1984) and the Emotion Regulation Checklist(Shields & Cicchetti, 1997); teachers rated children's behavior on the Problem Behavior Questionnaire(Behar & Stringfield, 1974). Data were analyzed by independent t-tests, correlations, and multiple regressions. Results demonstrated that shyness, activity, and emotion regulation had direct effects on hostile-aggressive behaviors. Shy temperament had a direct effect on fearful-anxious behavior. Both marital conflict and temperament influenced hostile-aggressive behaviors indirectly through emotion regulation, implying a crucial role of emotion regulation in preschoolers' social development.

  • The Local Agenda21 is an action program of local dimension to realize of sustainable development. The citizen participation is prime issues and very important f3r successful practice of the Local Agenda21. The purpose of this research is to analyze the citizen participation problem and to suggest the improvement plan at the advanced course of the Local Agenda21. The research results are as follows; 1. The recognize of citizen about the Local Agenda21 is very low. Namely, the citizen of about 50% answered not to know about the Local Agenda21, 2. However, citizens showed the participation opinion to be very active by simple explanation about the Local Agenda21. 3. Also, citizens showed the result to be very affirmative in the environment problem consciousness investigation. Namely, citizens were recognizing the environment problem as the problem of the society synergic.

  • This paper is intended to document the development of the Mathematics across the Curriculum (MAC) movement, following a mathematics problem solving model. Of course, just as new, related problems often arise after we have completed the solution of a current mathematics problem, so too, many questions remain regarding the future of MAC. Although preliminary assessments have been favorable, no broad-based evaluation of the impact of MAC has been conducted. To what extent has the promise of increased student understanding of mathematics and its connections to other disciplines been realized? What can be done to overcome logistical obstacles preventing instructors from working together in real schools settings? Are changes in institutional culture and relationships among academics merely transitory? Is the development of a strong base of curricular materials forthcoming? In other words, will MAC reach a level of educational permanence, or ultimately be discarded as another interesting, but unmanageable instructional fad?

  • The purpose of the article is to address a new instructional approach to a complex engineering course. We design a novel instructional method that combines mobile technology, simulation program, collaborative teamwork, problem-solving process, and a variety of evaluation techniques. We suggested five instructional principles that might be required to change the fundamental educational process by which learning is done. The proposed instructional method is expected to aspire for new perspectives on complex learning environment. Nevertheless we solely began by the research on the development of students' complex problem-solving performance in a complex engineering course, the new instructional method in the article can promote the adoption of new instructional methods and strategies across different knowledge domains. In addition, the instructional method can provide a valuable bridge to acquisition and transfer of problem solving, motivation, and meaning learning.
