The purpose of this study is to develop an in-service teacher training program for professional development in environmental education. In order to achieve the goal, the in- service teacher training program for professional development in environmental education development / implement team is formed to deal with the development and the implementation of the program. The team is composed of environmental education professionals and environmental education teachers. After the development of the program, 20 teachers were selected to implement the program. Then, through various researches such as interview, monitoring, and survey, the evaluation of the program was done. After the evaluation, the feedback on the program was collected in order to apply the final adjustments and changes to the developed training program for professional development in environmental education. The training program is designed to include the wide range of theories and real life cases. It focuses on certain topic, and is implemented through workshop type training method to increase the participation rate. The major motive of the participants was to develop their professionality in environmental education. Based on the analysis of the training program and the workshop, 69.1% of the program is focused on the environmental education/learning theory, and 71.4% is focused on the environmental education teaching method. The environmental education teaching method is focused on the real life teaching method that could be used in many schools. However, the parts on environmental education philosophy, psychology, and evaluation was not included as a part of the program. Also, the evaluation method of the students learning the environmental education was not introduced as a part of the program as well. It is due to the limited time frame of the training program, as well as its focus on the training method of environmental program. Based on the analysis of the evaluation results obtained through monitoring, the training program for professional development in environmental education is successful in terms of focusing the goal of the program around the environmental education/learning theory and environmental education teaching method, which was the motive of the participants. However, the effectiveness of the program differed from participants to participants based on their majors in environmental education, and it did not last long enough. The future training program for professional development in environmental education should consider the backgrounds of the program participants to have various programs prepared for various groups of people. We suggest that the results of this developed program will be applied to "environmental education teacher licence training" in the future.

This paper considers that a public department under specialized TQM manpower constraints have to implement multiple total quality management (TQM) policies to promote its service performance (fundamental goal) by adopting a centralized sequential advancement strategy (CSAS). Under CSAS, the decision-makers (DMs) start off by focusing specialized TQM manpower on a single policy, then transfer the specialized TQM manpower to the next policy when the first policy reaches the predetermined implementation time limit (in terms of education and training). Suppose that each TQM policy has a different desirous education and training goal. When the desirous goals for all TQM policies are achieved, we say that the fundamental goal will be satisfied. Within the limitation of total implementation period of time for all policies, assume the desirous goals for all TQM policies cannot be achieved completely. Under this premise, the optimal implementation sequence for all TQM policies must be calculated to maximize the weighted achievement of the desirous goal. We call this optimization problem a TQM case of "centralized sequential decision-making problem (CSDMP)". The achievement of the desirous goal for each TQM policy is usually affected by the experience in prior implemented policies, which makes solving CSDMP quite difficult. As a result, this paper introduces the concepts of sequential effectiveness and path effectiveness. The structural properties are then studied to propose theoretical methods for solving CSDMP. Finally, a numerical example is proposed to demonstrate CSDMP′s usability.

In this paper, we propose an implementation of a real-time operating system for the two-wheel mobile robot. With this implementation, we have the ability to control the complex embedded systems of the two-wheel mobile robot. The advantage of the real-time operating system is increasing the reliability and stability of the two-wheel mobile robot when they work in critical environments such as military and industrial applications. The real-time operating system which was ported to this implementation is open systems and the corresponding interfaces for automotive electronics (OSEK/VDX). It is known as the set of specifications on automotive operating systems, published by a consortium founded by the automotive industry. The mechanical design and kinematics of the two-wheel mobile robot are described in this paper. The contributions of this paper suggest a method for adapting and porting OSEK/VDX real-time operating system to the two-wheel mobile robot with the differential drive method, and we are also able to apply the real-time operating system to any complex embedded system easily.

The purpose of this study was to analyze the current implementation states of the differentiated curriculum at the middle school and to propose ways to improve it. For that purpose this study conducted a survey and had the interviews with the middle school mathematics teachers. The items of survey and interviews consisted of the two main parts: current states and needs about the special supplementary courses and enriched supplementary courses. The results showed that there were discrepancies between the current states and the needs of the differentiated curriculum. This means the efforts to improve the current states are needed. The strategies for improving the implementation of the differentiated curriculum are as follows: 1. The use of various standards including the subject-achievement level and students' or parents' opinions is needed in selecting the students of special supplementary course. 2. More relevant special supplementary materials need to be developed and utilized. 3. The ability grouping is recommended for the differentiated instruction. 4. The deliberation of developing the enriched and supplementary texts is requested. 5. The study for differentiated evaluation of students is demanded.

The purpose of this study was to figure out adoption of curriculum autonomy policy by a middle school. To achieve the purpose, official documents accepted or produced by the school were examined regarding how much curriculum autonomy was given to the school. As well as, minutes on curriculum organization and implementation and interviews with significant figures in the school were analyzed to reveal how the school exerted its curriculum autonomy. The results indicated that superior educational administrative institution that had made decision on curriculum autonomy policy and promoted it constantly sent to the school official documents that required it to report what had been done. Such practices prevented the school from autonomous organization and implementation of curriculum. In addition, as most decisions on curriculum organization and implementation at school level was made by administrator and teachers with special position, most teachers remained at passive status to accept what had decided by them. Parents'committee did not exercise their rights by lack of expertise and passive attitude.

The purposes of this study were to investigate the perceptions of teachers and students on the implementation of the intensive course completion system in mathematics courses and to provide suggestions for the improvement of the system. Five high school mathematics teachers and 338 10th graders and 87 11th graders in 2 high schools located in Gyeonggi-do participated in this study. The results of this study indicated that the intensive course completion system is more appropriate to the subjects which require less time allotment or practical exercise than mathematics courses. For better implementation of the intensive course completion system in mathematics courses, first of all, enough time allotment for teaching and learning mathematics should be guaranteed. Otherwise, the system can make students feel more burden of learning due to increase in learning volume of mathematics courses.

Objectives: This cross-sectional study aimed to identify the significant factors that influence small and medium-sized business workers when they carry out low sodium diet. Methods: The data were collected by conducting a survey on 161 individuals in small and medium sized businesses who had not been diagnosed with hypertension, in Gyeonggi province. The survey tool measured their knowledge in carrying out low sodium diet and how much support they had been given from their family. The data were analyzed by descriptive statistics and multiple regression analysis. Results: Family support affected their implementation of the low sodium diet (t=2.981, p=.003). Similarly, the result accounted for 27.2% ($R^2=.272$) in the regression model. Conclusion: this statistical results suggest that there is a profound need of various nursing intervention programs to enhance family support and to improve their awareness of the importance of implementing low sodium diet in order to prevent hypertension in small and medium-sized business workers.
