The purpose of this study is to analyze whether library field study expands students' understanding of their knowledge acquired in school. For this purpose, six major areas of LIS(Library and Information Science) and 29 sub-major knowledge were derived, and 19 fourth-year undergraduate students were surveyed before and after field study. The analysis showed that there was a difference in comprehension between the pre- and post-tests in the major areas where the students had direct practice, but there was no significant relationship between field study using Fisher's exact test. In the future, it is necessary to conduct a follow-up study with a long-term practice and a large number of students, and this study will be a step towards discovering the possibility that field study can make a positive contribution to the understanding of knowledge.

The purpose of this study is to identify the basic scientific knowledge of in- and pre-service elementary school teachers, specific areas having insufficient knowledge and the reason for the lack of understanding. For the study, we analyzed the survey asking basic scientific knowledge to in-service elementary school teachers within an urban communities and pre-service elementary school teachers enrolling the first, the second and the third year in National University of Education. The results shows that there is the lack of understanding about scientific knowledge such as boiling points, perihelion, substances, and elements, which elementary school teachers should have exactly known. With regard to the age, an effort is required to increase scientific knowledge of the in-service teachers in 50's, compared to those in 20s' and 30s'. In the pre-service teachers, the average in the third year was significantly higher than that in the first and second year. Regarding the major background in high school, both of in- and pre-service teachers who completed the science course showed significantly higher average than those who completed the liberal arts course. In addition, regarding the major in the university, the average of the group with science and engineering major was higher than that of the group with other majors.

The purpose of this study was to analyze elementary school teachers' understanding, certainty, and familiarity with 13 key concepts of wave physics that are presented in textbook and teacher's guidebook. 123 elementary school teachers answered concept tests and questionnaires. In the results to these tests and questionnaires, teachers demonstrated a high level of understanding and high certainty in understanding with regard to the concepts of sound generation, effect of medium on wave, timbre, wavelength, and trough and crest of wave. For the topics of sound velocity, wave reflection and wave transmission, teachers demonstrated a high level of understanding but low certainty in understanding. With regard to sound propagation, teachers demonstrated a low level of understanding and an improperly high certainty in that low understanding. Teachers lacked knowledge, i.e., displayed a low level of understanding and low certainty in sound strength, sound frequency, constructive interference and destructive interference. In constructive and destructive interference, the teachers also displayed a low level of familiarity. We analyzed the differences in teacher's understanding, certainty, and familiarity according to teacher demographics defined by the teacher's gender, teaching experience with concepts of sound, career, curriculum track while in high school, and major in university. There were no significant differences in understanding, certainty, or familiarity as defined by gender, teaching experience, and career. However, these displays of knowledge were affected by the teacher's curriculum track in high school and their major. These results suggest that the teacher's understanding of, familiarity with, and certainty in wave physics concepts are more influenced by their learning experience than by their teaching experience. Therefore, we suggest additional learning opportunities for teachers (such as teacher training programs) in order to improve teacher knowledge and correct teacher misconceptions in wave physics.

Recently research interest in Knowledge Management (KM) has grown rapidly. Companies regard intellectual capital as important asset and strive to deploy KM in an organization to gain a competitive edge. Many organizations currently engage in knowledge management in order to leverage knowledge both within their organization and externally to their shareholders and customers. Most of the previous research related to KM are dedicated to investigate the role of information technology in extracting, capturing, sharing, coverting organizational knowledge. Knowledge workers, however, are paid less attention though they are the key players in KM activities such as knowledge creation, dissemination, capture and conversion. We regard knowledge workers as a major component of KM and starting point of understanding organizational knowledge activities. Therefore we adopt a method to understand and analyze knowldge workers' social relationships. In this paper we investigate Social Network Analysis (SNA) as a tool for analyzing knowledge network. We introduce the basic concept of SNA and suggest a framework for implementing knowledge network by explaining how SNA can be used for analyzing knowledge network. We also propose a numerical method for identifying knowledge workers using SNA after classifying knowledge workers. The suggested method is expected to help understanding key knowledge players within an organization.

The purpose of this study through ethnographic inquiry is to describe how an elementary teacher teaches mathematics with understanding. The ways that teachers'beliefs affect instructional activities, what means understanding from the view of cognitive psychology, and ethnographic research tradition were reviewed to anchor theoretical background of this study. A third-grade teacher and his 45 students were selected in order to capture vivid and thick descriptions of the teaching and learning activities of mathematics. Three major sources of data, that is, participant-observation with video taping, formal and informal interviews with the teacher and his students, and a variety of official documents were collected. These data were analyzed through two phases: data analysis in the field and after the fieldwork. According to data analysis, ‘teaching mathematics with understanding’ was identified as the teachers central belief of teaching mathematics. In order to implement his belief in teaching practices, the teacher made use of three strategies: ⑴ valuing individual student's own way of understanding, ⑵ bring students' everyday experiences into mathematics classroom, and ⑶ lesson objectivies stated by students. It is suggested for future research that concrete and specific norms of mathematics classroom for the improvement of mathematics understanding are needed to be identified and that experienced and skillful teachers' practical knowledge should be incorporated with theories of teaching mathematics and necessarily paid more attention by mathematics educators.

We compared the understanding of 4 pre-service teachers of chemistry education major and 2 pre-service teachers of chemistry major related to conceptions of "properties of dilute solutions" chapter in high school Chemistry II textbooks. As results, few pre-service teachers understood fully the concepts of high school Chemistry II textbooks. Some pre-service teachers had misconceptions related to properties of dilute solutions. We found that few differences existed between the pre-service teachers' understanding regardless of whether they took a major in chemistry education of a education college or a major in chemistry of noneducation college. Most of the pre-service teachers who attended this research recognized the lack of practical knowledge in their pre-service teacher curriculum.

Purpose: This study was to investigate and analyze understanding and knowledge of the eye in biological science education for middle and high school students in Busan. Methods: A total of 821 middle and high school students from four different schools participated by self-administered questionnaire test. The results were compared and analyzed by grade and gender. Results: In the survey of the understanding about the eye in the biological science curriculum, the results indicated that the more learning of the eye in biological science lecture led to the more understanding of the role of the eye. The difference of understanding the eye between learned and unlearned students in biological sciences lecture was significant (p<0.01). In the survey of the knowledge of the eye, students did not know about myopia and astigmatism (average value <50). Conclusions: As biological science education is one of the major factors to understand the role of the eye, this result suggests that more information about the eye in the curriculum of biology is included.

As information systems are introduced in organizations, user attitudes toward IS are crucial factors for the success of such systems. Hence, understanding what affects user attitudes should be a major concern in MIS research. The purpose of this study is to improve the understanding of social influence on IS adoption. Social influence construct is stretched to include four items: subject norm, image, visibility, and voluntariness. Also, this paper examines the roles of two moderators regarding social influence: user characteristics and IT maturity. We could find that 1) social influence has a significant impact on perceived usefulness(PU), perceived ease of use(PEU), and intention, 2) the social influence on PU is more noticeable for knowledge worker than for undergraduate student, and 3) social influence on knowledge worker's PU is stronger for emerging IT(e.g., wireless internet services) than for mature IT(e.g., spreadsheet software).

The demands for knowledge in the rapid social change and the competitive environment are being increased day by day. As to reflect the demands, much scholarly and practical work has been done on the topics of Knowledge Management (KM). However, the study of KM in nonprofit organizations (NPOs) is insufficient. This study, while discussing the nature of NPOs, which have the different purposes of existence and characteristics from for-profit organizations, has the purpose of finding out the special strategy for KM in NPOs. Through understanding the characteristics and the status of NPOs, this study suggests that that the interorganizational KM is the method to lead successful KM in NPOs. And the critical success factors (CSFs) are presented in the three major factors, such as the systematical, the interorganizational and internal consideration factor for organization. This not only provides the successful KM strategy of NPOs but also enlarges the understandings about interorganizational KM.
