The purpose of this study was to compare and analyse the subject organization and teaching units of middle school science curriculums and science textbooks, by studying the organization of subject matter and content scope and level of middle school science subject in South and North Korea. As a result of this study, the composition, scope, and level of content between middle school science textbooks in South and North Korea were similar. However, the study found that science education objectives, separated science curriculum subject organization, economical efficiency weighted format and organization of science subject matter, result-centered experiments, the enlightenment of Kim Ilsung and his son in North Korea science education were very far from the desirable direction of science education. Therefore, the view on level-based curriculum and organization of the science curriculum should be integrated, and preparation of student-centered organization of textbooks and expansion of science-technology-society content is needed before unification. And also, the united Korea science curriculum shouldn't simply compromise or neutralize between middle school science curriculum in South and North Korea. They should make a future-oriented plan for information and globalism society.

This study investigated the level of academic passion for pre-service elementary teachers' science pedagogical content knowledge (PCK) and the factors that influence the passion. To this end, 182 first to fourth grade students in advanced non-science majors who were taking science-related courses in the second semester were selected, and two tests were then administered to evaluate their academic passions for science subject matter knowledge and science pedagogical knowledge. Individual in-depth interviews were also conducted with some of the participants. It was found that the factors such as "importance" and "harmonious passion" for learning science subject matter knowledge and science pedagogical knowledge were found at a high level. On the other hand, the factors such as "like" and "investment of time and energy" were slightly higher than normal, and the factor such as "obsessive passion" was slightly lower than normal. The differences in academic passion for science subject matter knowledge and science pedagogical knowledge were greater according to the high school track than the grade. The pre-service elementary teachers selected more often the factors such as "individual interests", "high school track", "contents of science-related courses at the university of education", "characteristics of professor in charge of science-related courses at the university of education", and "experience in teaching practicum" as the factors that influenced their academic passion for science subject matter knowledge and science pedagogical knowledge. However, there was a slight difference in the selection ratio depending on the high school track.

In response to complexity and diversity of a social phenomenon, the dispute also is various, therefore can not be settled efficiently by means of court adjudication to which applies a law strictly. To overcome such problems we are going to seek to make use of arbitration. According to Korean Arbitration Act Art. 3 (1), any dispute in private laws would be the object of arbitral proceedings. It could be the object of arbitral proceedings that disputes which are capable of a settlement by arbitration. It is a matter for debate that disputes containing punitive damages may be resolved by arbitration. This problem is concerning the arbitrability of the subject-matter of a dispute. To offer some solution to these issues, it is necessary to inquire into the nature of punitive damages. the policy and function of alimony, the fair apportionment of a loss. Moreover, international relations formed with international transactions should be considered. Punitive damages would be the object of arbitral proceedings as the dipute in private laws. When punitive damages pursue only punishment in the domestic arbitration that there is not foreign factors, arbitral tribunal could not make arbitral award containing punitive damages. However, if punitive damages are admitted under the rules applicable to substance of dispute, and there is the arbitration agreement in which is implied that the parties agree to submit to an arbitral award, arbitral tribunal could make arbitral award containing punitive damages in international arbitration. When it is questionable whether it is offend against our public policy or not, that we accept the effect of arbitral award containing punitive damages, and we admit the enforcement of it, we have to take the nature of punitive damages, the policy and function of alimony, the fair apportionment of a loss and the stability of international transactions into consideration.

Recently, a number of researches acknowledge the importance of 'reflection' and 'reflective teacher education,' and they highlight the implication of 'reflection' on the teacher's profession or the teacher education. The reflective thought is interpreted as a subject that should be taught or a sort of strategy that a teacher should learn, while the aspect is excluded that reflection is the interaction between the innate knowledge and the practice. As a result, the reflective teacher education programs that increase the level of reflection are developed and practiced, and the reflection is accepted as a tool for increasing teacher professionalism. Reflective teaching is en essential and basic element for the development of teacher knowledge. In particular, such teacher knowledge might be being gradually expanded by a teacher's self-assessment on reflection on his own instruction. For this reason, this study develops an assessment framework on instruction which is comprized of teacher knowledge and instructional process. To accomplish this, in this study, teacher knowledge is considered as a whole practice knowledge combined by subject matter knowledge, understanding of learners, teaching and learning methods and assessment, and instructional environment. Also, success on instruction in mathematics class might depend on the acquisition of teacher knowledge, instructional planning, instructional execution, and furthermore reflection on instruction. Especially, this study emphasizes that 'reflection on instruction', the most important step of instruction be reflected and examined by the teacher himself.

This paper is to inquiry into the conceptual model of religious education in school curriculum focused on 7th revised curriculum, subject matter and teacher training system. We have to consider the related variables for the operation of school curriculum: student, school, teacher. In school curricula of Korea, religious education can be practiced as a elective course of subject, discretion activity and special activity, latent curriculum etc. And also it should be considered student's right of option and autonomy of private school, because at least those are the important variables effect upon the religious education in school curriculum. Now I'd like to abstract results of this paper as followed. First, it should be considered student's right of option for religious education in private school curriculum. But at this case, also under the name of education it should be justified precondition of purpose, content, approach method. If not, it easy to access to pejorative meaning as a religious indoctrination. Second, in case of conflict between student and school, I think that a proper method is to adjust the related variables. Third, if the purpose of religious education in school based on religiosity, it can be cover the understanding of religious culture, affectionate domain of religiosity, behavioral religiosity. Finally, in order to accomplish such an conceptual model of religious education in school, it should be set a condition for teacher training system, subject matter etc.

Despite the rapidly growing body of research on science teachers' pedagogical content knowledge (PCK), most of the research has mainly focused on the definition of PCK and its components. The main purpose of this research was to explore the operational definition of PCK and to suggest another form by re-conceptualizing PCK, with the newly defined and conceptualized PCK capable of being used as standards and/or criteria in selecting the curricular content of and deciding the subject area of science teacher education. In this research, the science teachers' PCK was defined as the "practical knowledge and skills that are acquired through the curriculum of science education and in the course of teaching experiences, and which are used in their teaching of secondary school science." The science teachers' PCK was further defined as consisting of two integrated and/or combined dimensions: subject matter and pedagogy, each of which comprises several components. In this paper, the PCK is called science education literacy. The paper also presents the ways to apply the operational definition of PCK and re-conceptualized PCK and a few suggestions for the research on science teachers' PCK.
