This study is aimed to offer the elementary school teacher's experience and awareness about science field trip and science museum field trip, by analyzing the survey of 867 students and 81 teachers in Seoul. Research shows 67.9% high figure of elementary school teacher's experience on science field trip. That experience is include 61.8% of science museum using experience. In case of elementary school teacher's pre-activity is only 53.1% and most of them was visiting Website. Post-activity is more than preceding activity(74.1%) but method is too simple like checking work sheets. 62.3% of elementary school students have been to science field trip and science museum that is higher than teachers'. 66.5% of students said science field trip is influence on science study in good ways but there are some difficulties like lack of pre-activity(33.0%) and unkind information about science museum(21.9%). For activation of science field trip, resources development for effective science field trip operating, program development for pre- and post-activity, school group science field trip program development which is linked science curriculum, complement and expand activity information of science field trip institution.

The field is a good learning environment that offers many opportunities. Status of conducting field trip in the middle and high school was investigated As a result, there was few teachers who disagree that a course in science should include learning in the field. Yet, on practical side, teachers who used to conduct the field trip over once a year in science class appeared to be about 23% only. Most of schools conducting field trips hadn't well-planned program for instructional activities. Many of teachers appealed that they should not get release time for conducting an extended field experiences, and that they could not obtained good information in relation to the contents, the methods and strategies of field activities. It says that a good field trip needs administrative and financial surport, many informations, and the teacher's exertion.

Travel demand forecasting is the important process of transportation policy and planning, especially trip assignment is also important because it finds deficiency of network GIS can be applied to transportation due to its various merits. Recently Program development environment is changed to component-based and transportation-component is necessary. This study evolves in implementing trip assignment model with GIS and tries to apply the system to the Cheongju City.

The purpose of this study was to investigate beginning earth science teachers' perceptions about Learning in Geologic Field Trip. The hundred and sixteen high school earth science teachers who were in the training for their promotion answered the questionnaire of Learning in Geologic Field Trip. It was divided into five parts: needs and educational values, teachers' experiences and their difficulties, and desirable teaching methods of Learning in Geologic Field Trip. Results indicated that the participants perceived Learning in Geologic Field Trip important in earth science education and responded positively to the educational values of Learning in Geologic Field Trip. Most of the beginning teachers had experience of geologic field trip, but did not learn how to teach it to their students during the geologic field trip in the pre-service training program. It was shown that only a few teachers had experience of geologic field trip and of teaching students in the outdoor of geologic fields after they became a classroom teacher. Most of the participants perceived that teaching students about the geologic field trip is difficult because of lack of their experience. In order to overcome the difficulty, teachers suggested that they need to learn how to teach the geologic field trip to students through their in-service training. leachers suggested that a desirable teaching method of the geologic field trip is to provide teachers with a teacher's manual including geological explanation and information about field trip sites before their visit so that they can scaffold it and facilitate the students' cooperative group activity during the field trip. As a follow up activity, the participants agreed that the presentation and discussion about the results should concur.

It is necessary to find out the parallelism in tlle sequential Java program to execute it on the parallel machine. The loop is a fundamental source to exploit parallelism as it process a large portion of total execution time in sequential Java program on the parallel machine. However, a complete parallel execution can hardly be achieved due to data dependence. This paper proposes the method of exploiting the implicit parallelism by structuring a dependence graph through the analysis of data dependence in the existing Java programming language having a nested loop structure. The parallel code generation method through the restructuring compiler and also the translation method of Java source program into multithread statement. which is supported by the Java programming language itself, are proposed here. The perforance evaluatlun of the program translaed into the thread statement is conducted using the trip cunt of loop and the trip Count of luop and the thread count as parameters The resttucturing compiler provides efficient way of exploiting parallelism by reducing manual overhead conveliing sequential Java program into parallel code. The execution time for the Java program as a result can be reduced un the parallel machine.

The present study proposes an innovative approach to develop educational contents for the field trip with creative activities. In the study, the field trip with creative activities extends students' learning spaces from not only the classroom but also social circumstances. With the use of the Creative Resource Map (CRM) for students' field trip, students can approach to rich contents whenever and wherever they want. For this, it is necessary to have a variety of curriculum-related contents. For the content development, it is important to enhance mutual cooperation between school and local community as well as to create local capacity for the development of the u-learning contents with smart devices.

Bulk of toner residual quantity detection return trip conglutinated in toner of using printer current is comparative big state by using PCB substrate, therefore is incongruent to use in light weight print miniaturized more. Return trip this development miniaturizes such as this by doing one chip competitive product develop chip has to be conglutinated compulsorily in toner used to printer announced since 2005 years. Therefore, demand of chip to be used in forward revival market may be thriving. Production of revival toner is impossible by chip conglutinated to printer to meaning that manage information of toner cut ridge that universal laser printer makers are used in printer and do customer service. In this paper, we develops chip conglutinated compulsorily to produce revival toner.

The loop is a fundamental for the parallelism exploiting as it has a large portion of execution time for sequential Java program on the parallel machine. This paper proposes the method of exploiting the implicit parallelism through the analysis of data dependence in the existing Java programming language having a single loop structure. The parallel code generation method through the restructuring compiler and the translation method of Java source program into multithread statement, which is supported in the level of the Java programming language, are also proposed here. The performance test of the program translated into the thread statement is conducted using the trip count of loop and the thread count as parameters. The restructuring compiler makes it possible for users to reduce overhead and exploit parallelism efficiently in the Java programming.

The purpose of this study was to examine the cases of the head family's costume culture and to apply them to field experience education of adolescent's home economics subject. To examine costume culture, women in the two head families in the Hampyeong area, Jeollanam-do were interviewed. The findings had unique shroud making and custom in the Mo's head family of Hampyeong. Also it was found that the eldest daughters-in-law of the Lee's of Hampyeong have horizontally exchanged the information of the head family's costume with village women of the same family. They have initiated their costume culture directly through their daughters and it had the great influence on after-ages. The Spot experience program for adolescent to experience the head family's costume culture and life culture consisted of four subjects:(l)Educating the head family's traditional living culture including etiquette training, (2)head family village walk, (3)experiencing the head family's clothes life including natural dyeing and sewing, and (4)a field trip of Hampyeong Local Life Culture Museum. For a model experience of the head family's costume and life culture, three families with middle and high schoolers participated in 8- hour experience learning program.
