This study examines respondents' perception of influence of corporate social responsibility on the corporate effectiveness. Also it investigates the relationship between Machiavellianism and corporate social responsibility. Survey data were collected from undergraduate business students, Advance Management Program attendants and business professors of Hallym University. The results show that they perceive corporate social responsibility's positive contribution to profitability and success. Older respondents thought more positively about contributions of corporate social responsibility to short-run success than younger ones. Also Machiavellian scores of older ones were lower than those of younger ones. The findings indicate that Machiavellianism influences directly respondents' perception of corporate social responsibility. It implies that understanding of human nature is important to induce corporate managers to be socially responsible.

The purpose of this study was to analysis characteristics and changes of epistemic thinking in middle school students on class-argument activities in an argument-based inquiry(ABI) science class. Data was collected from class recording video and activity worksheets of five subjects argument-based inquiry. Results of the analysis of student epistemic cognition characteristics show that experimental data was presented the most as evidence, and depending on the ABI activity, personal experience-based evidence and evidence based on scientific principles were used. As a result of analyzing the changes between claims made before and after class argumentations on five ABI activities in an argument-based inquiry science class, student claim modifications could be classified, according to reasons for the modification, into three types: correcting incorrect claims, clarifying unclear content, and expanding the concept.

Digital preservation becomes, nowadays, one of the important business process in the academic libraries. This study is to investigate the librarians' perception on digital preservation requirements and to analyze the business practices of the digital preservation and digital preservation level in the 102 academic libraries. In results, it is found that the digital preservation specialists in academic libraries have almost same perception on basic policies and direction. Also, the study finds that the important function of digital preservation is to secure authenticity and integrity; policy and expertise are the most important key components for digital preservation; the most frequently reported barriers to preservation are the lack of willingness and funding problems; most librarians want to learn and train how to establish preservation planning and policy. In general, most librarian think that the level of digital preservation in the academic libraries is insufficiency. Therefore the academic libraries should establish the relevant digital preservation policy and business workflows and to develop capacity of digital preservation.

본 연구는 세 종류의 Porphyromonas gingivalis(Pg) antigen의 IgG subclass associated recognition을 평가하기 위해 수행했었다. 총 35명의 조기발병형치주질환자중, Pg381에 대한 IgG2항체의 증가를 보이는 5명이 급속진 행형 치주질환자, IgG4의 증가를 보이는 6명의 환자(국소유년형 치주질환자 2명과 급속진행 형 치주질환자 4명), IgG2+4의 증가를 보이는 2명의 급속진행형 치주질환자 그리고 IgG1+2+4의 증가를 보이는 8명의 환자(국소 유년형 치주질환자 2명과 급속진행형 치주질환자 6명)으로 구성된 21명의 환자를 dot immunoblot analysis를 위해 선택했다. 실험에 사용된 정제된 항원은 Pg381에서 추출한 43-kd fimbrilin protein과 lipoplysaccharide(LPS), Pg A7A1-28(ATCC 53977)에서 추출한 capsularpolysaccharide(CPS)였다. Immunoblotting pattern은 IgG4 antibody가 fimbrial antigen에 강력히 반응함을 보여주었다. Fimbriae에 잘 반응하는 몇몇의 IgG4 antibody역시 antigen에 대해 양성반응을 보였다. 대조적으로 IgG2는 CPS antigen을 일차적으로 인식했다. 전부는 아니지만 대부분의 경우, single이나 group화된 IgG subclass는 모두 LPS antigen을 인식하지 못했다. 같은 group에서 염색강도의 개인적인 차이는 증명되었다. 이런 결과는 조기발 병형 치주질환에서 Pg의 fimbriae와 CPS가 immunodominant antigen이 될 수 있음을 제시한다. 더욱이 IgG subclass antibody가 이런 Pg의 immunoglobulin antigen을 선택적으로 인식함을 알았고, 이는 조기발병형치주질환의 병리에 immunodominant antigen과 함께 IgG의 기능적인 역할을 고려해야 함을 제시한다.

Company's interest in the work place training and investment has been growing continuously because the talent of human resource is the competitiveness itself in the knowledge based society. However, corporate training programs mainly have focused on large companies and SMEs despite the economic business volume have been treated too lightly so far. This paper regards corporate training programs with one of the methods for SMEs innovation and proposes the smart learning in the smart device diffusion. Concretely, this paper analyzes the utilization intention, each attribute and level in smart learning characteristics using conjoint analysis. The result shows that SMEs have positive response for smart learning acceptance and SMEs consider significantly the usage fee type and location with the difference between regular employee and administrator. Specially, interactive communication and customized contents are preferred in the training type. Smart learning can be used as strategic means in supporting the value innovation and enhancing the absorptive capacity in SMEs innovation process.

This study was conducted to obtain a better understanding of Korean researchers' motivations and experience regarding open access publishing. An online survey was conducted with the Korean authors of PLOS ONE, a major open access mega journal (OAMJ). A total of 238 responses were collected; the analysis was based on 202 valid responses. The results of the survey were compared and constrated with the results of a major international study that investigated similar issues. For Korean authors with open access publishing experience, journal impact factor (JIF) is still the most important factor in making publishing decisions. There was a significant difference between general publishing venue decision making versus open access publishing venue decision. Overall, Korean authors are far less satisfied with open access publishing than the authors in the international study. The results suggest comparatively low level of expectation among Korean researchers toward open access publishing. Open access policy and training initiatives are needed to promote open access.

Although various efforts to increase the usage of the Yeouido Saetgang river have been made after it was established as the first ecological park in 1997, its usage is significantly lower compared to neighboring Yeouido Han river park. In this study, an interview survey of 1,000 visitors to Yeouido Saetgang river park was conducted. The perception and activity patterns among the visitors were examined. The results showed that about 60 percent of all users were neighboring residents who can move by a walk. Most of the visitors spend their time in the river park taking exercises and observing the ecosystem. It is similar to the characteristics of other city parks in Seoul. The perceptions and activity patterns according to the visitor's characteristics were analyzed statistically. Also, the effect level of activity patterns on the perceptions such as satisfaction, attachment, and willingness to participate was analyzed and discussed.

The purpose of this study is to draw implications for future Korean science education by analyzing the PISA 2015 science teacher questionnaire. To this end, descriptive statistics and difference tests were conducted for each questionnaire item, using raw data from science teacher surveys in Korea, the United States, and China. As a result of the analysis, first, the perception that Korean science teachers should participate in professional development activities was lower than that of comparative countries, and it was found that improvement was needed in the practice of adaptive instruction and various evaluation methods. Second, although Korean science teachers were generally satisfied with their jobs, the response that they were hindered in science education activities due to limitations in various resources at their current school was relatively higher than that of comparative countries. Third, scientific inquiry was less emphasized in science curriculum and science class in Korea, and self-efficacy in inquiry teaching process was relatively low. Fourth, in Korea, it was found that there were fewer classes for discussion and using ICT in science classes.

The purpose of this study was to examine the potential of the use of the Classroom Response System (CRS), a kind of new ICT medium, in a quiz problem-solving oriented high school life science class. To find the usefulness of CRS as a teaching and learning strategy, the CRS group (n=34) sent prompt individual answers to the teachers' questions using the CRS terminal (Clicker), and the teacher then asked additional reasons of the individuals and gave personalized feedback. In the control group (n=35), the CRS was not used while the teacher asked overall questions and gave feedback in an undifferentiated way. As a result, the CRS increased students' interest and concentration during class, but there were no significant differences in study achievement between the two groups. However, there were significant differences between the medium-level groups when the two groups were divided into smaller ones based on their pre-scores. We suggest that, for effective use of the CRS for diagnostic and formative assessment, teachers should develop a teaching and learning strategy that can produce appropriate questions of various levels in advance, investigate the exact reasons for students' answers, and give customized feedback by individual as much as possible.
