This Qualitative study investigated a preservice teacher's developing views of learning with the influence of constructivist epistemology taught in the Math, Science, and Technology Education (MSAT) Master of Education (M. Ed.) preservice teacher education program. The MSAT teacher education program employs constructivist aspects of teacher education and generates applications of constructivism to the practice of teaching, as revealed by faculty interview data. It is important at this point to emphasize that there are significant epistemological and ontological differences between different versions of educational constructivism (i.e., individual, radical, and social constructivism) and that these differences imply different pedagogical practices. For the 16 preservice teachers included in a larger study, the epistemological and ontological characteristics for each teacher's developing views of learning were identified through four in-depth interviews. Data from interviews were used to construct a constructivist profile for each preservice teacher's views of learning (i.e., a profile containing ontological beliefs, epistemological commitments, and pedagogical beliefs). Of the sixteen participants in the larger study, five significantly changed ontological and epistemological beliefs and eleven did not. Profile changes for the five who did change also resulted in changes in their conceptions of science teaching and learning (CSTL). In this article, one of the five teachers case was presented with rich quotes. This case study documents how a preservice teacher transferred his ontological and epistemological beliefs to his pedagogical beliefs and maintained the consistency between his philosophical beliefs and CSTL. It also demonstrated implications that changes in components for an educational constructivist profile have for a preservice teacher's view of himself as teacher. Data indicated the possibility that a constructivist-oriented preservice teacher education program can influence students' conceptions of science teaching and learning by explicitly introducing constructivism as an epistemology rather than as a specific method of instruction. Implications for both instructional practices of teacher education programmes and research are discussed.

The purpose of this study is to analyze the relationship between mentor teachers' mentoring characteristics and mentee teachers' reflective practices and to investigate mentor teachers' mentoring methods to enhance mentee teachers' reflective practices based on the analysis. The participants were four beginning science teachers and four mentors who have more than seven years of teaching experience. This study compiled mentor and mentee teachers' journals, records and transcripts from mentee teachers' five periods of classes, lesson plans, evaluation forms of lessons, one-on-one mentoring records and transcripts, questionnaires conducted before, during, and after the mentoring program, and a questionnaire about the effects of one-on-one mentoring. The mentoring characteristics of mentor teachers were analyzed based on mentor's interaction methods and the contents and frequency of the support based on teaching feedback. Mentee teachers' reflective thinking was analyzed by being categorized as voluntary self-reflections of their classes and reflections on the support provided by mentor teachers. Mentee teachers' reflective practices were analyzed by utilizing RTOP. The conclusions of this study are as follows: Mentor teachers could promote mentee teachers' reflective practices by eliciting conversation that helped mentees perceive problems in their teaching practices. Mentors' questions evoking mentees' reflective thinking could elicit mentees' spontaneous self-reflection, and it led to the enhancement of self-reflection on mentors' support and reflective practices. When mentors offered the support based on teaching practices while playing a role as a facilitator to help mentees identify and solve problems by themselves, mentees' reflective practices could be promoted.

Switching to organic farming practices in agricultural production reaches the end of the period it takes an average of five years. During this period, agricultural soil management to improve the investment must be sustained. Results of the survey of environment-friendly agricultural lease rates appear to approximately 54.2% lower than agricultural practices. Environmentally friendly agricultural land is leased on a long transition period of the contract cost, many buried incompleteness, uncertainty of contract fulfillment(opportunistic behavior) occurs when the transaction costs. This ultimately can hinder the spread of organic farming. Thus, the qualitative development of organic farming and land leasing in order to minimize transaction costs, should that occur. The alternative 'cooperative long-term lease contract' is a system.

The purpose of this study was to examine what factors affect the construction of preservice white mathematics teachers' racial identities and the relationship between their racial identities and Culturally Relevant Teaching (CRT) practices. We examined five white female preservice teachers who enrolled in an elementary mathematics methods course at a private university in the US. We collected data consisting of lesson plans, semi-structured interviews, and reflection of a taught lesson in the 2018 fall term and examined them using qualitative research methods. We found that preservice teachers' racial identities were affected by their backgrounds, K-12 school experiences, and practicum school environment. We also found a relationship between teachers' sensitivity to racial issues and their endorsement of CRT strategies. The findings also revealed that the relationships were mediated by practicum school contexts. Based on the findings, we provided practical implications for the teacher education programs.

This study examined what questions posed, and for arranging the matters, what decisions made, what practices put into by elementary preservice teachers during his or her enacting and reflecting mathematics teaching. Analysis of the study focused on the mathematics instructions practiced by four participants in practicum for senior students. Their own questions raised by each one in the instructional designs, performances, and reflections were picked out and categorized by five dimensions of mathematics instruction; the nature of classroom tasks, the role of the teacher, the social culture of the classroom, mathematical tools as learning supports, and equity and accessibility. Their instructional decision-makings and action-takings for answering to these questions were analised.

The purpose of this paper is to find out the present status of public library management. The assumptions on which this research is based are that there are differences between th theories taught at the educational institutions for librarians and the practices actually managed at libraries, and that the differences are greater in Korea than those in the United States of America as the former has a shorter library history and is a more bureaucratic society. The data were collected were collected through the questionnaires sent to fifty-five public library managers in Taegu and Kyungpook province. Forty-two respondents replied, making the returned rate of 76.4%. The results show that there exist some differences between theories and practices, but they are not so great as expected. It was found out that there is a difference between what the theorists state and what the practicing managers accept. It was also found out that the library managers agree that the new management theories and techniques can be adopted to their libraries. The hindering factors are found out, and based on the findings, a few suggestions are provided.

Dr. S. R. Ranganathan's Five Laws of Library Science were published in 1931 which is a classic work. This article describes in detail the Five Laws of Library Science and their implications on library activities. These laws have provided a scientific approach to library science. They constitute the philosophical basis for work and services of all types of libraries. These also provide guidance in the practice of Library and Information Science. He author emphasises that these will provide source of inspiration and guidance in the years to come. Every student and teacher of library Science and librarian must give a thought to the implications of these laws. In the changing environment of libraries in the emerging society has to fall with in the purview of these laws. The imperatives motivated by these five laws at the time of Ranganathan and in the present days have been identified. The new interpretations of the five laws with the various current nomenclature of Library and Information Science and other allied subjects have been enumerated. These new interpretations of these Laws shows that in today's international world of librarianship, Ranganathan's Five laws are much important and relevant what was before and even it is increasing. These Laws became the cornerstones of the philosophy of the techniques of Western society's library experts. The author concludes that the vision and legacy of Ranganathan will continue to be an inspiration and guiding spirit for the emergence of the new library and information profession. These will serve as source of inspiration and guidance in the years to come. It is not whether Ranganathan is by himself relevant to-day, but it is we who can make him relevant by studying and applying his principles and practices in different areas of library management.

Objectives : With Taoist medicine, there is a way of improving one's health by adopting a unique discipline called 'Five viscera spirit meditation'. The method was reintroduced in traditional Korean medicine when it was finalized. The viscera figures in the Uibang-yuchwi is one of the good examples in which the photos influenced by the five viscera spirit meditation appeared in medical literature. This research is aimed to study the process and the result of how medical knowledge influenced the formation of the five viscera spirit meditation, an important health theory of Taoist medicine, and how Korean medicine was affected by Taoist medicine. Methods : We will compare and study the information included in the following publications: the Taipingjing from the Dong-Han Period when the concepts of five viscera spirit were conceived; the huangtingjing from the Wei-Jin-Nan-Bei-Chao Period when the five viscera spirit meditation was finalized; the Yuanshenjing, the Yuzhoujing and the Buxietu based on Taoist medicine; and the Uibang-yuchwi based on traditional Korean medicine. Results & Conclusions : SThe medical knowledge at the initial stage made its way into Taoist medicine, forming the foundation of health theories and contributing to the creation of the five viscera spirit meditation. After some exchanges of medical knowledge and practices between Taoist medicine and other existing medicines, the five viscera spirit meditation reappeared in medical literature in the form of drawings and was used to cure diseases.
