The purpose of this study was to examine school-level science elective-centered curriculum operation and teachers' perception of their instruction of elective-centered science courses. Data were collected from 12 science teachers in 12 high schools in the metropolitan Seoul area through semi-constructed interviews. The results showed that students were supposed to select science subjects under insufficient guidance and their choices on subject were also restricted due to school administrative processes such as teacher's instructional time allocation. Participants were well-perceived different group characteristics among humanities course and science course students toward science learning, still, they felt difficulties in valuing students' variety by differentiating contents and teaching methodologies due to school assessment system and workload of extra instructional material preparation. Influenced by the current college entrance examination system, low motivation for humanities course students and students' choice concentrated in chemistry and life science for science course students, were pointed out as main problems. As a way to improve science education for 11th - 12th graders, developing customized science curriculum for humanities course and science course respectively, changing of entrance system into increasing importance of science for students who will major in non-science fields, and designations of essential prerequisite science subject for students who will major in engineering & science fields, were suggested.

Korea's social cooperatives were enacted by law in December 2012. However, it is in the process of being settled and has not been established institutionally. So social cooperatives are failing. The purpose of this study is to reduce these failures. To this end, this study distinguished between co-operatives and social co-operatives. Also, the characteristics and concepts were identified. That is why we want to help our social cooperatives in Korea. The results based on the literature research are as follows. First, in order for domestic social co-operatives to be sustainable, the seven principles of co-operatives must be observed. In particular, the sixth principle is important. It is important to form a social cooperative association and to communicate with local cooperatives. Their communication is less likely to fail because they can share management support information, education, promotion, and strategies. Second, there is a need for a plan that can be applied not only to the government but also to general enterprises in order to support social co-operatives. Third, related policies of the government and the private sector should be designed and managed in an integrated manner to promote social cooperatives. Fourth, public relations should be promoted through campaigns to inform the public that the meaning of social cooperatives is for the public good. In addition, the government needs to build a program that fosters professionals who can foster social co-operatives. In conclusion, it is meaningful that this study suggests possible ways to develop social co-operatives in Korea, and provides support to the Korean government.

This study is to search the problems of schoolyard teaching material developed by pre-service earth science teachers and the critical factors affecting material making. The 258 schoolyard teaching materials was collected from 54 pre-service earth science teachers (male: 18, female: 36) major in Earth Science Education in Jeonju, Korea. The schoolyard teaching materials was greatly influenced by making process type of it and the prior knowledge of pre-service earth science teachers. As schoolyard preference exploratory type rely on their prior knowledge to develop the schoolyard teaching materials, they made use of the limited concepts like fault in material making. But the concept preference exploratory type made use of concepts not accessible to majority of pre-service earth science teachers because they selected a concept from the earth science textbook first of all. The pre-service earth science teachers having wrong prior knowledge selected inappropriate resources, as well as fell into the error of concept connecting. The pre-service earth science teachers having right prior knowledge partly considered only shape of resources, but had a disregard for formation process of it in material making. Accordingly, we need to reflect richly Geological Field Trip and Solid Earth Science to curriculum for earth science teacher education. And we have to educate pre-service earth science teachers to create holistic concept on the geological subject matter knowledge, field based teaching and learning strategy, material making process.

It is frequently pointed out that the conventional field survey for natural environment has may limitations in terms of positional accuracy, real-time GIS data acquisition, and economic efficiency. The aim of this research was to develop an on site real-time mapping technique that enables the surveyor to input data in the field. The idea is based upon the recent trends in the field of Telecommunication and Information Technology that uses a GPS, wireless network computing, moving computing, etc. A virtual office approach has been adopted, in which a portable computer is linked to a GPS and field workers record data on the computer at the site and analyse data on site. This field mapping system has shown to be much less susceptible to the positional accuracy than that of th conventional approach. The Graphic User Interface, in particular, were ideally suited to combining positional information with attribute data which changes with every survey points. This interface allows users to interactively display and query GIS layers reproduced from the past survey results. The GIS database stored in the virtual office will serve to carry out a highly reliable survey since it could play a crucial role in identifying temporal and spatial changes occurred in the site. It is expected that integrated utilization of field data among the related agencies would be increased much more than before since the virtual office survey would be a powerful tool to ensure geometric fidelity in GIS database creation process. This paper also discusses the limitations and future direction of the present prototype research.

The purpose of this study is to develop human resources and management system model for home-based welfare services. For the purpose of the study, both of method of literature review about home-based welfare services and previous research and survey were used in the study. The subjects of the survey were Junior and senior high school students, the employed, housewives, the disabled, and the aged. They were considered as human resources for the home-based welfare services. Based on the result of the survey and related theories, the study suggests the model for the development of volunteers and management system composed of recruitment, education and training, disposition, management and supervision, and evaluation for home-based welfare services. Assuming linking and cooperation between volunteer center and agency using volunteers which provide home-based welfare services, the model was developed. The role of volunteer center is recruitment, education and training. The agency using volunteers is responsible for education, disposition, supervision, and evaluation related to practice. In the stage of recruitment, elaborating strategy considering characteristics of group was suggested. In the campaign, use of mass media, selection of timing, equal opportunity for all group were suggested. Also outreach strategy as a effective recruitment strategy was presented. In the stage of education and training, method and content of education in each stage of primary education and re-education were presented. In the stage disposition, method and content for the right volunteer in the right place were suggested. In the stage of management and supervision, supervision by coordinator and necessity of using volunteers as para-professionals was suggested. Also the necessity of program operation for volunteer maintenance and management was discussed. In the stage of evaluation, time, main body, and method of evaluation was suggested.

This study reviewed the stuttering literature and reported the clinical experiment in stuttering intervention. There is still no single answer as to the cause of stuttering or to the most effective therapy for stutterers despite the vast amount of research. One certain thing is that we have come closer to a better understanding of the stuttering and to more effective therapy. There have been three main statements about the origins of stuttering ; biologic origins ; psychodynamic origins ; environmental-learning origins. There also have been various methods of the treatment of stuttering. Broadly, two major treatment approaches are attentive ; stuttering modification therapy and fluency shaping therapy. In this experiment, the researcher attempted to investigate complex elements that each child might have and to use an integrative approach rather than to keep the specific one. Individual subjects were evaluated by a multidisciplinary team. Initially, the subjects received individual therapy. They then were placed in group therapy. The purpose of the group therapy was to raise their fluencies to the higher communicative situation and to maintain improved fluency over time. All three subjects improved their fluencies in reading and in conversation and showed the better(SSI)scores in total stuttering behaviors. It was also discussed that it is necessary to have sensitive assessment tools to investigate each element of stuttering ; and to develop a therapy program reflecting current advanced stuttering theories.

The visual implementation of 3-dimensional national environment is focused by the requirement and importance in the fields such as, national development plan, telecommunication facility deployment plan, railway construction, construction engineering, spatial city development, safety and disaster prevention engineering. The currently used DEM system using contour lines, which embodies national geographic information based on the 2-D digital maps and facility information has limitation in implementation in reproducing the 3-D spatial city. Moreover, this method often neglects the altitude of the rail way infrastructure which has narrow width and long length. There it is needed to apply laser measurement technique in the spatial target object to obtain accuracy. Currently, the LiDAR data which combines the laser measurement skill and GPS has been introduced to obtain high resolution accuracy in the altitude measurement. In this paper, we first investigate the LiDAR based researches in advanced foreign countries, then we propose data a generation scheme and an algorithm for the optimal manage and synthesis of railway facility system in our 3-D spatial terrain information. For this object, LiDAR based height data transformed to DEM, and the realtime unification of the vector via digital image mapping and raster via exactness evaluation is transformed to make it possible to trace the model of generated 3-dimensional railway model with long distance for 3D tract model generation.

The purpose of this study was to investigate the vocational identity through the reflection of the major experience as the teacher through the life history of the technical high school. In order to achieve the purpose of this study, two technical high school mechanical and career teachers were selected as research participants and in-depth interviews were conducted with them. The data obtained through the in-depth interviews were analyzed through six steps. Six major experiences of the participants were identified as results of the research: (1) the experience of trying to train the specialist of precision machining in the beginning of teacher's life, (2) experience as a skill competition team teacher, (3) experience of innovating public education by introducing new industry field, (4) experience of constant learning new field and sharing with colleagues, (5) experience in the rapid change of the status of technical high school, (6) experience in the prevention of students' safety accidents and maintenance of the practice field. Through these educational experiences, each research participant was forming one's vocational identity as a mechanical teacher. The vocational identity of the research participants were identified as follows: (1) identity drifting phase, (2) identity stability stage, (3) transition stage of the teacher role, (4) suspended stage to preserve identity, (5) identification sublimation stage, (6) identification of the true meaning of the teacher, and integration of the identity. Through these six steps, their identities were formed, strengthened and changed at each stage.

Elementary school teacher selection test has to be implemented for knowledge(MKT) to estimate and to be a step in the expansionary direction. For this, It has to be analyzed closely in terms of teacher's MKT first that questions set from selection tests until now. In this research, some standards were established by type of question, grade, contents field and subject from 84 mathematics questions set at examinations. And it was analyzed concretely by general tendency and produced the results of analysis related to elementary teacher's MKT in elementary school teacher selection test since year 2000. The results showed that descriptive and short answer type was mostly set(71.4%) in type of question and integrated grade type was mostly set(41.7%) in type of grade in elementary school teacher selection test. And in type of contents field, rated from highest to lowest, number and operations(31.0%), measurement(23.8%), figure(15.5%) were set. Textbook/manual(34.5%), solution of problem(26.2%), learning psychology(13.1%) in status of subject were followed in order, but there's no relationship with estimation. This research was based on a standard of precedent study and made an analysis of elementary mathematics questions of selection test since year 2000. Therefore, it has a meaning because of produced results from analysis related to elementary teacher's MKT.
