Purpose: The purpose of this study was to measure the effects of a school safety education program based on the PRECEDE-PROCEED model for upper grade elementary students. Methods: One hundred ten 6th-grade students sampled from an elementary school in D City were divided into the education group (n=55) and the non-education group (n=55). School safety education was provided to the education group for 8 weeks and a questionnaire survey about safety knowledge, safety practice and the frequency of safety negligence was carried out before and after the education from March 2 to July 13, 2010. Results: After the application of the safety education program, the education group got a higher safety knowledge score than the non-education group (p<.001). Both the education and non-education groups showed a significantly increased safety practice score (p<.01). In the comparison of safety negligence, the education group showed lower frequency (p<.01). In addition, according to the results of ANCOVA and t-test, the school safety education program influenced safety knowledge significantly (p<.001). Conclusion: This result shows that a school safety education program based on PRECEDE- PROCEED can improve safety knowledge. Further studies will be required to develop continuous and systematic safety education programs.

The aim of this paper is to provide teacher awareness and the status of robot based instruction(RBI) by focusing on the school curriculum. To gather that information, we conducted a questionnaire survey composed of six items to 116 teachers who have had experiences on RBI. The questions are about the fit school year for RBI, the fit subjects for it, the possibility of applying it to regular subject, the fit students' learning levels for it, the fit learning styles for it and effective methods to apply it to regular subject teachers. The result is as follows: (1) RBI is suitable for fifth and sixth grade in elementary school and all grades in high school. (2) It is suitable for all regular subjects in all schools. (3) It is more effective for the students who have average learning level. (4) It fits into introverted students more than the other style of learners. (5) It is likely to be more effective in supporting of learning and understanding of the contents than merely assisting the teachers' instruction. (6) The teachers showed positive awareness on applying RBI to subject of creative activities. The results are significant in relation to the following two views. First, we can get the positive possibility in applying school curriculum using RBI. Second we can foresee that RBI will provide an innovative paradigm to school curriculum. In addition, the results of this paper can be used as preliminary information for developing models and programs on RBI.

The purpose of this study is to provide the school planning factors as emergency shelter after disaster. The school functions as the evacuation space areas could be classified into the evacuation center, education maintenance, and dwelling. Among these functions, the scopes of our study are limited to the functions of evacuation center and education maintenance. To carry out this purpose, we were comparative analyzed the shelter space problems of Korea and Japan's survey in the existing literatures. In results of our study, the evacuation center's functions are difficult to depending on the disaster types, such as the earthquake, tornado, and hurricane. On the other hand, the education maintenance functions are difficult to deepening on the victims occupied times in the school as emergency shelters. Based on these findings, the Korea school planning as the emergency shelters are desired to reflect that the evacuation's functions based on the disaster type of the damage from storms, and the education maintenance's functions based on the victim's occupied times in school for their safety.

Project-based learning is an innovative approach to learning that teaches a multitude of strategies critical for success in the twenty-first century. Students drive their own learning through inquiry activity, as well as work collaboratively to research and create projects that reflect their knowledge. The purpose of this study was to investigate the effects of eco-friendly school project activity which is applied from one of project-based learning approach on learning outcomes of students in ninth-grade environment course in middle school. The participants were given a questionnaire before and after the environmental project activities. In solving the school environment issues themselves, students have practiced invaluable problem solving skills. This study indicates that school students' awareness about the environment has positively changed by experiencing the eco-friendly school project. In addition, this project affects students' variety of environmental awareness. This project could be applied to school environmental education programs and to environment lessons, developmental activities or club activities for a positive impact on students' environmental awareness.

The aim of this paper is to show the possibilities of the proficiency -based and integrated teaching of High School English reading and listening based on sense group and utterance restructuring. The proficiency -based and integrated listening and reading activities in stages are as follows. Step1, students fill in the blanks with strong or weak sounding words according to their abilities. Step2, speak along (track) based on restructuring and post-lexical phenomena while listening to the sentence. Step3, read and understand directly the passage, which have been marked the differentiated places where a native speaker of English would beat all likely to pause. Students need to listen to spoken English, so they recognize words in written and spoken form. They must be familiar with suprasegmental features, stress and rhythm, and post-lexical phenomena during reading activities.

The model based method for energy saving of the separately excited DC motor drive system is proposed in the paper. The accurate power loss model is necessary for this method. Therefore, the adaptive tabu search algorithm is applied to identify the parameters in the power loss model. The field current values for minimum power losses at any load torques and speeds are calculated by the proposed method. The rule based controller is used to control the field current and speed of the motor. The experimental results confirm that the model based method can successfully provide the energy saving for separately excited DC motor drive. The maximum value of the energy saving is 48.61% compared with the conventional drive method.

We propose a feature-based multi-resolution representation of B-rep solid models using history-based Boolean operations based on the merge-and-select algorithm. Because union and subtraction are commutative in the history-based Boolean operations, the integrity of the models at various levels of detail (LOD) is guaranteed for the reordered features regardless of whether the features are subtractive or additive. The multi-resolution solid representation proposed in this paper includes a non-manifold topological merged-set model of all feature primitives as well as a feature-modeling tree reordered consistently with a given LOD criterion. As a result, a B-rep solid model for a given LOD can be provided quickly, because the boundary of the model is evaluated without any geometric calculation and extracted from the merged set by selecting the entities contributing to the LOD model shape.

In this paper, we propose the modified uniformly most powerful (UMP) belief-propagation (BP)-based decoding algorithm which utilizes multiplicative and additive factors to diminish the errors introduced by the approximation of the soft values given by a previously proposed UMP BP-based algorithm. This modified UMP BP-based algorithm shows better performance than that of the normalized UMP BP-based algorithm, i.e., it has an error performance closer to BP than that of the normalized UMP BP-based algorithm on the additive white Gaussian noise channel for low density parity check codes. Also, this algorithm has the same complexity in its implementation as the normalized UMP BP-based algorithm.

In this paper, a new background subtraction algorithm for video based fence monitoring surveillance systems is proposed. We adopt the sampling based background subtraction technique and focus on the two main issues: handling highly dynamic environment and handling the flickering nature of pulse based IR (infrared) lamp. Natural scenes from fence monitoring system are usually composed of several dynamic entities such as swaying trees, moving water, waves and rain. To deal with such dynamic backgrounds, we utilize the confidence factor for each background value of the input image. For the flickering IR lamp, the original sampling based technique is extended to handle double background models. Experimental results revealed that our method works well in real fence monitoring surveillance systems.
