In this research, we investigated the effects of mathematics education in using Socrates , method in a course of mathematics education in teacher's college. And we proposed some suggestions for education of future mathematics teachers. This study was conducted with 44 university students(third grade) who entered the department of mathematics education (future mathematics teachers) in 2005. We took a course in curriculum that was required for the future mathematics teachers in my department. In this course, we began with the reading the famous dialogue between Socrates and Meno's slave. And we analysed Socrates' questioning of Meno's slave and tried to understand what this dialogue is implicating in mathematics education. All the participants in this course was divided 11 groups. Each group designed a school mathematics class plan using Socrates' method and practiced their teaching plan by a performance(students' announcements). Through the analysis of research data. Five effects of mathematics education in using Socrates' method for future mathematics teachers were induced. Therefore, we suggest that future mathematics teacher need to have many opportunity to design and practice a mathematics teaching plan by using mathematics teaching-learning methods taught in their course.

The previous study has assumed that dialogue and debate could not have been activated by the hierachical Confucian norm and political authoritarianism in Korean society. Political democracy has developed in Korean society since 1987. But many observers have pointed out that the culture of debate still remained undeveloped in Korean society. This study assumes that the key factor of determining the quantity and frequency of debate is the polilitical factor such as authoritarianism, but the determining one of qualitative dimension such as debate competence derived from the epistemological tradition. In order to ascertian this hypothesis, this study explored the epistemological basis of Confucian thoughts in comparison with the classical Greek thoughts. In classical Greek society, philosophers considered that the purpose of debate is to find and to ascertain the truth. Bur Confucian scholors didn't look upon questioning the truth. Instead they considered practicing or doing of the truth worthful. Therefore, in a society which were much influenced by the Confucian thought, the culture of debate could not have been developed.

Purpose: The purpose of this study was to compare the clinical efficacy of popular bone graft materials mineralized allograft and deproteinized bovine bone mineral. Materials and Methods: One hundred seven implants of 78 patients, accompanied by sinus lift using the lateral window technique and simultaneous implantation, were sampled. In addition, some patients with severe systemic conditions were excluded. The initial bone heights of all patients ranged from 3-6 mm. All of the sample cases were treated at our hospital from January 2005 to January 2008. Techniques other than the lateral window technique were excluded, and only one graft material ($Tutoplast^{(R)}$ or Bio-$Oss^{(R)}$) was accepted for inclusion. $Tutoplast^{(R)}$ was used in 63 implants of 41 patients, whereas Bio-$Oss^{(R)}$) was chosen for the remaining 44 implants of 37 patients. The diameters of the particles used ranged from 0.25-1.0 mm, and the volume was 0.5-2 cc (mean, 1.5 cc). Results: The survival rate of the implant fixtures was 99.07% when the lateral window technique was used. Among all of the cases, cases in which $Tutoplast^{(R)}$ was used demonstrated a survival rate of 98.4%, whereas Bio-$Oss^{(R)}$) resulted in 100% survival. With respect to the alveolar bone height, no significant differences were detected between the two graft materials that failed. Conclusion: According to the result reported above, the two common materials for sinus augmentation do not have clinically significant difference. Rather, host factors, such as the height of residual bone, which could be disclosed during questioning patients' systemic conditions, might have greater effects on the prognosis.

The purpose of this study was to analyze teacher's teaching-learning strategies and young children's concepts related to mathematics and science in integrated mathematics and science education activities. To achieve this purpose, actual class episodes were analyzed. The episodes were derived from 7 sessions of interaction between teacher and 4 kindergartners in integrated mathematics and science education activities. As a result of the study, children's concepts related to mathematics and science in integrated mathematics and science education activities occurred three factors: the relationship between weight, shape and movement, the relationship between weight and size, and the concept of measurement. In teacher's teaching-learning strategies, three factors were revealed: teacher's questioning, use of teaching materials, and children grouping.

The purpose of this study is to promote the status of environmental education and environmental awareness among employees in company levels. To achieve the study purpose we measured the infrastructure of companies (e.g., re-education programs and social contribution activities) and how these enhance environmental awareness to the employees. The survey was conducted by questioning 100 company employees. The questionnaire was composed of two parts : 1) environmental pollution and 2) nature conservation. The Chi-square test and one-way ANOVA was applied to compare groups. The results can be summarized as follows : First, the environmental education for employees in companies is insufficient; however, environmental education should be necessary and the employees provided with environmental education by their companies appeared to be highly satisfied (p<0.05) than groups without appropriate environmental education. Second, volunteer workers for participating environmental education programs and events are rare; however, employees who participated in volunteer efforts scored the highest in environmental awareness. Third, those that participated in environmental education programs and volunteer works were ranked the highest in environmental awareness (p<0.05) in 10 categories of questions. Based on the study, the environmental education and the volunteer work appeared to be effective tools in boosting environmental awareness among company workers. In conclusion, environment oriented volunteer work is an effective way to improve environmental awareness toward adults.

Background : Qigong is an energy-healing intervention used to prevent and cure ailments and to improve health through regular practice. Although qigong-neither itself nor its postulated mechanism of action-are within the paradigm of modern Western medical science, its effects on the human body could be possible. Objectives : This study aims to review the bibliography, biological responses and therapeutic effects of Qigong. In the process, this review will grasp trends in this field of studies and will direct further researches into the right direction. Method : The computerized Korean databases were searched from their respective inceptions up to January 2008. The search terms used were 'qi', 'qigong', 'doin', 'training', 'bioenergy', 'life nurturing' and random or Korean language terms related to qigong. Several specialized journals were also manually searched for relevant articles. Result : Since the 1990s, Qigong papers in the Korean Literature are increased. The articles on Korean traditional medicine had been published more than those on physical education or nursing etc. However, since the majority of the trials determine questionnaire, it was difficult to determine the efficacy of a specific intervention. The methodological quality of the trials was generally low (Jadad score: mean, 1.3; range, 1 to 4), questioning their reliability. Conclusions : More profound studies for Qigong are needed. Further rigorous clinical trials with more objective outcome measures that include sham procedures should be performed. Specifically, we think it should be clinical studies and qualitative research methods for evaluation are needed.

This study conducted an analysis of types of reasoning shown in students' solving a problem and processes of students' reasoning according to type of problem by posing an open-ended problem where students' reasoning activity is expected to be vigorous and a multiple-choice problem with which students are familiar. And it examined teacher's role of promoting the reasoning in solving an open-ended problem. Students showed more various types of reasoning in solving an open-ended problem compared with multiple-choice problem, and showed a process of extending the reasoning as chains of reasoning are performed. Abduction, a type of students' probable reasoning, was active in the open-ended problem, accordingly teacher played a role of encouragement, prompt and guidance. Teachers posed a problem after varying it from previous problem type to open-ended problem in teaching and evaluation, and played a role of helping students' reasoning become more vigorous by proper questioning when students had difficulty reasoning.

"Interactivity refers to the possibility of an audience actively participating in the control of an artwork or representation." Andy Cameron, Dissimulations Interaction can be described as a way or function that improves the participation of audiences/viewers to being immersed into the medium itself. Until now, however, in terms of interactive cinema, interaction has not shown a sufficient participation for audiences. Specifically, audiences/viewers described that the structure of storytelling has failed to satisfy their requirements, in order to participate in the structure of storytelling. The aim of the research itself, therefore, began to ask and wonder why audiences/viewers criticised the participation which audiences/viewers are able to control storytelling, in interactive cinema, could not satisfied them in order to control and follow a storyline of interaction. In general idea, in interactive cinema, the function which allows audiences/viewers to be immersed into the storylines, must allow the immediacies of interaction. Audiences/viewers must therefore be able to satisfy the general idea of interactive cinema through controlling the directions of every choice offered. They must also be able to be immersed in the interactive storylines. Which of the prime causes can be improved or re-considered, to satisfy the participation requirements of audiences/viewers? The intention of this research also began to investigate a suitable method of storytelling within a narrative structure of interactive medium (interactive cinema). Through questioning the matter (it will be described in a later chapter), this research will be focused on the relationship between narrative structured interaction and audiences/viewers, which is of prime importance in relation to interaction. To further the research, Pilot study (experiment with the basic interactive narrative structure) was offered in order to understand and maintain a suitable method of storytelling within a narrative structure of interactive cinema and it also was explored to understand how the aim of the research would be maintained for further qualitative research.

Target businesses mean a business of specific and detailed management targets being used for realization of applications for business. Though elicitation methods of target businesses exist variously, it mostly requires much experience and consumes much time. So because its procedure is not suggested clearly, there is much difficulty when a beginner elicits target businesses. Accordingly, this study proposes a method capable of eliciting target businesses procedurally from given business statements. And hypothetical business statements were used as a case, and a method proposed from this study was applied to given business statements with the target of undergraduates, graduate students and company employees. And as a result of questioning an individual performance method and analyzing its reliability, a reliable result was obtained generally. Due to this, it could be confirmed that the method suggested in this study is not only used in the field, but also can be used easily even for a beginner.
