  • The purpose of this study was to investigate beginning science teachers' perceptions of inquiry-based science instruction using open-ended questionnaire and semi-structured interview. Participants of this study voluntarily set up a goal of inquiry-based science instruction, planned inquiry-based science lessons, and shared and reflected their teaching experiences in their professional learning community for more than a year. Participant teachers recognized students' construction of core scientific concepts through performing scientific inquiry as a goal of science inquiry instruction. Participant teachers indicated that goals of science education such as 'learning scientific core concepts', 'improving students' interest of science', 'improving scientific thinking', and 'understanding the nature of science' can be achieved through students' active engagement in scientific inquiry. Participant teachers recognized not only the importance of teachers' role, but also what roles science teachers should play in order to enable students to perform scientific inquiry. Participant teachers emphasized teachers' roles such as 'identifying core concepts', 'reorganizing science curriculum', 'considering student ability', 'asking questions and providing feedbacks to students', 'explaining scientific concepts', and 'leading students' argumentation.'

  • This paper investigates the process of change in the meaning of the term gongye (工藝) (nowadays it means craft) during Korea's transition to the modern era. The Annals of the Joseon Dynasty (朝鮮王朝實錄) will serve as the basis for the examination of pre-modern usage, and the Korea-United States Treaty of 1882 for the changes that occurred between the translation from Chinese and from Japanese following the opening of the port . After the port opened, the meaning of gongye, which once broadly referred to the wide range of work of people from different fields, was narrowed down to singularly represent the manufacturing industry. Following the example of Japan, the first East Asian country to succeed in modernization, this new meaning of gongye was generally used in the context of embracing Western culture and creating industry. As industrialization emerged as a national mission, and new terminology was needed to express these new concepts, the Chinese characters used by the Japanese to translate Western concepts were directly imported and used without making any changes. Gongye was similar in meaning to gongeop (工業) (nowadays it means industry) at the time, and the two terms were used interchangeably. However, following the Japanese annexation of Korea, the cultural administration of the Governor-General imbued the term with artistic concepts, and gongye was differentiated from gongeop, As such, examining the establishment of terminology and concepts can be helpful for understanding the contradictions and problems of the Korean crafts scene, which were derived from a period in the past called the modern era.

A Discussion on the Controversy of Relation between the Five Changes theory(五行論) and the Five Viscera from "Geummun-Sangseo(今文尙書)" and "Gomun-Sangseo(古文尙書)" (금(今).고문상서(古文尙書) 오행배장(五行配藏) 논쟁(論爭)에 대한 고찰(考察))

  • The five viscera[五藏], one of the key concepts from Traditional Oriental Medicine in understanding the nature of human body, endows the characteristic of five phases[五行] on the five representative organs, based on the five phases theory[五行論]. Although the theory from "Geummun-Sangseo(今文尙書)" which states the order of 'liver-mok[肝木] heart-hwa[心火] pancreas-to[脾土] lung-geum[肺金] kidney-su[腎水]' is now widely approved by present-day academics concerning arrangement of five changes and the five viscera, there are some other less-known theories of arrangement. "Gomun-Sangseo[古文尙書]" had suggested the order of 'pancreas-mok[脾木] lung-hwa[肺火] heart-to[心土] liver-geum[肝金] kidney-su[腎水]', which was never practiced, and "Dong-uisusebowon(東醫壽世保元)" of Ijema(李濟馬) expressed the theory of 'lung-mok[肺木] pancreas-hwa[脾火] heart-to[心土] liver-geum[肝金] kidney-su[腎水]'.

  • The purposes of the present article are to suggest pragmatism as offering a philosophical paradigm for mixed methods research, to explain the fundamental principles of mixed methodology, and to present examples of research for understanding how to apply it to family studies. Mixed methods research is the class of research where the researcher mixes or combines quantitative and qualitative techniques, methods, approaches, concepts or language into a single study. Mixed methodology has its roots in pragmatism, which is a new philosophical paradigm to criticize the traditional dualism and to endorse eclecticism and pluralism. The present article argues that mixed methods research has the potential to answer a broader and more complete range of research questions, and to provide strong evidence for a conclusion through convergence and corroboration of the qualitative and the quantitative methods.

  • The present study explored whether the implementation of focused activities (intervention programme) can enhance 22 pre-service mathematics teachers' proficiency in solid geometry thinking level as well as change for the better their feelings in this discipline. Over a period of 6 weeks the pre-service teachers participated in activities and diversified experiences with 3D shapes, using illustration aids and actual experience of building 3D shapes in relation to the various spatial thinking levels. The research objectives were to investigate whether the intervention programme, comprising task-oriented activities of solid geometry, enhance mathematics pre-service teachers' mastery of their geometric thinking levels as well as examine their feelings towards this discipline before and after the intervention programme. The findings illustrate that learners' levels of geometric thinking can be promoted, entailing control on higher thinking levels as well as a more positive attitude towards this field.

  • This study identifies how management theory and philosophy work in conjunction with and support one another as both are critical to understanding leadership concepts and viewing the design organization holistically in terms of organizational behavior and performance. This paper analyses data from an in-depth single-case study at management in interior design organization in Korea. Two new 'most efficient and effective way' to achieve the goals of the design organization has been launched. The first was organizational behavior and performance, and the second a needed new paradigm of management skills. Organizational culture affects organizational effectiveness in design because it can (a) provide an organization with a competitive advantage, (b) improve the way an organizational structure works, and (c) increase the motivation of designers to pursue organizational interests. Moreover, the result of research creates paradigm of thinking that how leaders in the design organization need to focus on innovative and strategic systems to gain competitive advantage and enter global markets; a key inter-organizational cooperation strategy to achieve a targeted goal.

  • Since the last 50 years, the terminology 'risk' has been widely used in general and industrial applications, with different meanings. The different definitions of risk can lead to the different risk assessments and risk management process elements, and the misunderstandings. For the reasons, the ISO(International Standard Organization) has recently defined a new risk concept through the publication of IS0 31000:2009. Although the new concept of risk was globally accepted, it seem to be argued in its definition debate. Thus, this paper reviews the definition and meaning of the concept of risk in terms of risk origin, general and industrial applications, related domestic laws and risk management standards published to improve an understanding of risk concept.

  • The flexible mathematical thinking - the ability to generate and connect various representations of concepts - is useful in understanding mathematical structure and variation in problem solving. In particular, the flexible mathematical thinking with the inventive mathematical thinking, the original mathematical problem solving ability and the mathematical invention is a core concept, which must be emphasized in all branches of mathematical education. In this paper, the author considered a case of flexible mathematical thinking with an inventive problem solving ability shown by his student via real analysis courses. The case is on the proofs of the equivalences of three different definitions on the concept of limit superior shown in three different real analysis books. Proving the equivalences of the three definitions, the student tried to keep the flexible mathematical thinking steadily.

  • In recent offshore industries, various ambiguous terms have been used without clear definition or classification, causing difficulties in legal, technical, and educational understanding and usage. For an example, the commonly used term of 'Offshore Plant' in Korea is not an universal word technically. There has been no clear technical or legal definition about the 'Offshore Plant' and its classification is also very ambiguous; sometimes it is used to refer offshore oil and gas production platform or it is used to mean offshore renewable power generation plant in some cases. To build a conceptual framework, therefore, this paper suggests a classification of offshore units (1) using internationally agreed terms, (2) agreed with the technical classification used by the ship classification society and (3) being able to include not only the current but also future concepts of offshore units.
