This study explored the core management competencies of ventures formed by the entrepreneur's incubator organization and startup experience in the biomedical industry in Korea. An in-depth interview was conducted with 13 entrepreneurs of biomedical ventures. Based on the previous literature, the core management competencies of the ventures, which are influenced by the incubator organization and startup experience, are classified into 'technical competency', 'organization management competency', 'network competency' and 'market pioneering competency'. Analysis of the in-depth interview has revealed 18 factors influencing the formation of the core management competencies of ventures. Qualitative factors that were not addressed by the previous empirical studies were identified in this study. These include 'confidence in technology development', 'way of performing R&D', 'organizational culture' etc. This study is characterized by its scarcity as a qualitative study that deals with the entrepreneurs' prior experience. In addition, this study categorize the core management competencies which are formed by entrepreneurs' incubator organization and startup experience as four factors. This result is expected to be useful in future research.
In medical industry, health insurance bill audit is unique and essential process in general hospitals. The health insurance bill audit process is very important because not only for hospital's profit but also hospital's reputation. Particularly, at the large general hospitals many related workers including analysts, nurses, and etc. have engaged in the health insurance bill audit process. This paper introduces a case of health insurance bill audit for finding reducible health insurance bill cases using decision tree induction techniques at a large general hospital in Korea. When supervised learning methods had been tried to be applied, one of major problems was data imbalance problem in the health insurance bill audit data. In other words, there were many normal(passing) cases and relatively small number of reduction cases in a bill audit dataset. To resolve the problem, in this study, well-known methods for imbalanced data sets including over sampling of rare cases, under sampling of major cases, and adjusting the misclassification cost are combined in several ways to find appropriate decision trees that satisfy required conditions in health insurance bill audit situation.
In recent years, the subject of peer rejection in school settings has received increased attention in the massmedia and counseling literature. This study focused on the effect of individual and environmental factors on peer rejection. Dependent variable was the number of perpetrating peer rejection and independent variables were psychological, behavioral, familial factors, exposure of peer rejection and perception about school policies. Ordered Probit model was employed because of the nature of limited dependent variable. The data were collected from 714 middle-school student in Seoul. Major findings were as follows. First of all, the adolescents who has aggression and problematic behaviors in school were more likely to participate in peer rejection. Second, negative parent-children relationships and the family structure didn't have significant effects on peer rejection. And there were not a significant effect of attitude toward academic value and academic achievement on peer rejection. Third, environmental risk factors such as negative peer relationship and the exposure to rejection had a significant increasing effect on peer rejection. But consistent school policies didn't have a significant effect. In conclusion, this study confirmed that peer rejection in school settings was affected by school environment such as negative-peer relationship, and exposure to rejection. Therefore, comprehesive and systematic intervention programs should be required to ensure that all the pupils at school have a right to learn in a safe and fear-free environment.
In order to provide quality services across international airports, airline personnel must rapidly and effectively develop and share knowledge. Combining components of adaptive structuration theory (AST) and media synchronicity theory (MST), a research framework was developed to convey three distinct stages of knowledge sharing. We use the grounded theory research method for the qualitative data collected from audio transcripts of employees learning how to use and work with company issued smartphones with push-to-talk functionalities. Data was collected from 33 operations personnel. The results of the content analysis are recorded for the elements of each of the three concepts of our research framework. During the social interaction stage, the content of the audio conversations shifts mainly from conflict management to task management; for media synchronicity, from quality to quantity; for productive outcomes, from efficiency to commitment. New insights are uncovered from our analysis of data from the field as users advance from learning how to use the mobile devices, to using the devices for managing knowledge for their work in the airline industry.

This study aimed to investigate the validity and appropriate way of career education according to the integration of home economics subjects, as a way of revitalization of career education in technology and home economics subjects, after the implementation of free semester system. For this goal, the meaning and trend of free semester system, trend of subject-integrated career education, analysis of curriculum in technology home economics education subject, and trend of research about career education in home economics were investigated. The result was as in the following. First, in spite of the ambiguity of the meaning of free semester, the career education will be expanded as the importance of lifelong career education was more and more required. Second, the career paths separated from subjects had problem in its effectiveness, therefore, subject-integrated career education emphasizing on school subjects will become more crucial. Third, it was presented that extracting core achievement standard in subject-integrated career education in technology home economics education according to core achievement standard was critical. For these reasons, the objective and model of career education in home economics education under free semester system were illustrated.

This study is the first part of the investigation of the students' and teachers' understanding of ideal conditions in physics. To do this, here, we provided the theoretical basis for the above study by discussing the meaning and characteristics of idealization. Idealization, introduced and elaborated by Galileo therefore characterized the nature of modem science, can be generated by four procedures: neglecting the minor variables, giving without any description about the minor variables, assuming the limit case, assuming constancy or uniformity. Idealization generated by these procedures can produce models and laws from the sensory informations about real world. And physics world is constructed by formalization or mathematization of these models and laws obtained through idealization about real world. Therefore, it can be said that idealization have a major role in the context of discovery. By this aspects, physics world can be viewed as the approximation of the real world, and this view, again, give rise the philosophical debate about the reality in nature. Idealization take an important role in the process of application of physics world and the understanding the real world. That is, physicists accept the discrepancies between real world, and physics world and make a great effort to explain, moreover, reduce these discrepancies by modifying or eliminating idealization involved in physics world. Continued from this study, we will proceed to obtain the implications of idealization on the physics learning and investigate the students' and teachers' understanding of the ideal condition involved in the theoretical explanation and the experiment in physics.

The purpose of this study was to investigate the gifted students' view on argumentation and the aspects of the argumentation in problem-solving type experiment. As a result, very lively argumentation was identified but quality enhancement on argumentation wasn't found over time. Students made frequent use of dialogic argumentation component, and especially, request & response component was highly used. Though usage frequency is low, the component of ground & question on ground was shown in 3rd class, and simple agreement gradually reduced, and reinforcing elaboration & metacognitive question has slightly increased. Also, students' argumentation were closely related to teachers' teaching approaches as some teacher-led steps doesn't appear in students' argumentation. By comparison in steps, 'problem solving activity & result analysis' step included 2 times more argument components than the previous step. We also found that method grouping teams does not almost affect the argumentation of gifted students. By survey results, most students recognized that they experienced free argumentation and this program activate argumentation and 'strange things' or 'difficulty' of program topics are obstacles in vitalization of argumentation. 'Surface growth experiments' was the most lively argumentation topic. The argumentation was lively made in the step of 'finding solution. 'Teachers' scaffolding accelerate the argumentation and help resolve difficulties in argumentation. Thus, students have positive recognition for the argumentation process in the experiments and recognize that argumentation process is needed.

This is a case study on two schools practising integrated science education (hereafter ISE). The purposes of this study are to investigate the types and features of ISE in the schools actively practising ISE, to identify the contextual factors of the schools, and to give implications for implementing ISE in schools. This study investigated the contextual factors in practicing ISE with a focus on the two schools, a middle school in Gyeonggi-do and a high school in Busan. They were breaking down the boundaries among teaching subjects and providing student-oriented instruction with problems in the real world. The data were collected by observing classes, by interviewing teachers, and by reviewing school documents and students' reports. The research findings are as follows: first, the two schools took part in ISE actively. They teach science to students providing integrated experiences mainly by using interdisciplinary knowledge and/or by solving the problems pertaining to the real world. While the former integrated subjects centering on topics, the latter focused on a project-based learning driven by students. They have differences in regard to the role of teachers and students, the level of integration and the type of integration. Second, the contextual factors that enabled ISE to be implemented there were found. The previous studies revealed six contextual factors in practising ISE: small and stable learning environment, leadership, team activities, in-school planning time, flexible timetable and community links. This study also found similar factors. However, the cases of this study provided ISE on a large scale and in a short period of time, instead of a small and stable learning environment. Teachers viewed the process of ISE not only as a tool to overcome the conservative culture of teachers but also as a pursuit of innovation.

The purpose of this study is to explore high school students' perception of the relationship among science, history, and history of science which is one of the career elective subjects in the 2015 revised science curriculum. This study compares students' perception before and after experiencing history of science course. To do this, data in the format of Venn diagram that students draw to represent their perception on relationship between the history of science, science, and history were collected. The collected data were inductively categorized. As a result of analyzing the Venn Diagram data, there are five different kinds of categories: 'History of science as an intersection of science and history,' 'History of science as an independent domain,' 'History of science as part of history,' 'History of science as part of science,' and 'History of science encompassing both science and history.' And there were 27 different sub-categories within the 5 categories. In addition, before taking the course on history of science, many students tended to regard science history as the intersection of science and history. However, after the course, students' perception changed and differed according to their affiliated academic track. For the humanities, history of science is perceived as part of history, and for the students in science track it is perceived as a part of science. Based on these findings, we suggest that history of science teaching-learning should be conducted that help high school students to experience a new perspective that is different from the curriculum in affiliated academic track.
