The purpose of this study was to evaluate a group activity, reciprocal peer tutoring (RPT), in order to investigate advantages and challenges of RPT in promoting cooperative and collaborative learning environment for EFL University reading instruction. The participants in this study were 89 students taking an English reading course at a Korean university. RPT is a learning strategy whereby learners help each other and learn by teaching. This program was supported by a Vygotskyan perspective which assumes that learners gain mastery and develop cognitive skills through social interaction with more proficient others and their environment. This study relied particularly on participant perceptions through questionnaire survey and Anonymous Online class Report of the course. This study showed various advantages for tutors such as learning through teaching and becoming more autonomous and responsible for their own learning. Non-threatening and highly motivating learning atmosphere are parts of benefits for tutees. Other advantages for tutees included improved level of academic self-confidence, and motivation. This study also revealed several drawbacks associated with the problem of inaccuracy in students' production and students' demand for more direct teacher role. (182 words).

과학지식 생산 유통의 투명성, 효율성, 신속성을 제고하기 위하여 새로운 학술 출판 모델이 시도되면서, 동료 심사 이력의 검증과 개방을 위한 피어 리뷰 플렛폼도 활성화되고 있다. Publons는 3백만명 이상의 전 세계 연구자들의 동료 심사 이력을 추적해 검증하고 공개할 뿐 아니라 업적으로 인정하기 위한 글로벌 플렛폼이다. 본 연구는 Publons를 활용해 국제 학술지 심사 위원으로 활동하는 국내 대학 소속 연구자 579명을 선별해 동료 심사 활동을 분석하였다. 분석 결과 첫 번째, 국제 학술지에서 활발한 심사 활동을 하는 국내 연구자는 공학, 의약학 분야에 많으며, 대부분의 분야에서 높은 국제 학술지 출판 실적을 보유한 조교수급 이상의 교수들인 것으로 나타났다. 두 번째, 모든 학문 분야에서 극단적으로 높은 심사 논문수를 보이는 소수의 심사자가 존재하였으며, 심사자의 신분, 나이, 국적에 따라서 심사 논문수와 심사 보고서 길이에 유의미한 차이는 존재하지 않았다. 마지막으로 심사자의 심사 논문수와 SCI 급 출판 논문수 사이에는 약한 상관성(r = 0.311)이 존재했지만, 많은 연구실적을 보유한 연구자가 그만큼 많은 국제 학술지 심사 활동을 한다고 말하기 어려운 것으로 분석되었다.

In developing countries, biogas energy production is seen as a technology that can provide clean energy in poor regions and reduce pollution caused by animal manure. Laboratories in these countries have little access to advanced gas measuring equipment, which may limit research aimed at improving local adapted biogas production. They may also be unable to produce valid estimates of an international standard that can be used for articles published in international peer-reviewed science journals. This study tested and validated methods for measuring total biogas and methane ($CH_4$) production using batch fermentation and for characterizing the biomass. The biochemical methane potential (BMP) ($CH_4$ NL $kg^{-1}$ VS) of pig manure, cow manure and cellulose determined with the Moller and VDI methods was not significantly different in this test (p>0.05). The biodegradability using a ratio of BMP and theoretical BMP (TBMP) was slightly higher using the Hansen method, but differences were not significant. Degradation rate assessed by methane formation rate showed wide variation within the batch method tested. The first-order kinetics constant k for the cumulative methane production curve was highest when two animal manures were fermented using the VDI 4630 method, indicating that this method was able to reach steady conditions in a shorter time, reducing fermentation duration. In precision tests, the repeatability of the relative standard deviation (RSDr) for all batch methods was very low (4.8 to 8.1%), while the reproducibility of the relative standard deviation (RSDR) varied widely, from 7.3 to 19.8%. In determination of biomethane concentration, the values obtained using the liquid replacement method (LRM) were comparable to those obtained using gas chromatography (GC). This indicates that the LRM method could be used to determine biomethane concentration in biogas in laboratories with limited access to GC.

This paper aims to explore the success factors of knowledge management in the perspectives of knowledge management integration into operations and to examine the effect of those factors on the knowledge management performance of individual users and organizations in order to link knowledge management performances to operational performances. I found two factors such as "knowledge management integration into operation processes" and "knowledge management integration into application systems" and their measures by means of literature review and modified Delphi research. Exploratory and confirmatory factor analysis confirmed that those two factors and their measures are statistically valid. Besides, the structural equation modeling analysis showed that the relationship between "knowledge management integration into operation processes" and "individual user's performance on knowledge management" and the relationship between "individual user's performance of knowledge managemen" and "organizational performance of knowledge management" are significant.

The purpose of this study was to investigate the factors that influence safety rule violation at work. Semi-structured interviews were conducted with 337 participants from nine manufacturing plants. The results of the content analysis revealed the following six categories: Individual characteristics, safety commitment, safety support and resources, safety competence and communication, production pressure, and problems with rules. Among the 14 factors in the six categories above, indirect accident experience in the individual characteristics category and no action for complying with laws in the problems with rules category had not been identified in previous studies. However, some factors, such as age, peer pressure, pay type, the lowering of risk, a masculine way of working, and supervisor position were not found in this study. The implications and limitations are discussed.

The purpose of this paper is to present a model to design the layout of the user interface components that handles many numbers of qualitative factors. An alternate rating system is also proposed for the closeness relationship ratings between the various pairs of components evaluated by using GOMS (goals, operators, methods and selection rules) technique. The proposed model is applied to the design of the part of the user interface in order to obtain the best layout of the components. The results of the proposed model are compared with that of an existing model, which handles single qualitative factor applied to obtain the layouts of user interface components.

This paper presents two social and academic studies on the boundary between cultural production and consumption. The first line of the study on cultural omnivore analyzes the choice of heterogeneous audiences in the face of various cultural offerings. The second line is a study of market categories, which analyzes the responses of peer audiences to objects with different levels of category code compliance. As such, this paper developed a heterogeneous audience model to evaluate objects of different types. This allows us to consider two dimensions of cultural preference: diversity and orientation of selection. To this end, this paper proposes a new analytical frame work to map consumption behavior on these two dimensions. The results suggest that one type of target that values diversity and transformation is particularly resistant to those that span boundaries. We test this argument in the analysis of two large data sets on film and restaurant reviews. Overall, our findings can extend beyond cultural consumption. Outline variability of contextual individuals or individuals in the same situation can cross cultural boundaries even if they are not intentionally pursuing such hybridism.

Objectives: The purpose of this study is to provide current the recent information on indium-related adverse health effects and the Korean indium-related industries. Methods: Peer review papers were searched in environmental, occupational and medical journals with the keyword of 'Indium' and 'ITO' and reviewed. To determine the indium related industries and indium consumption amounts, references and database were investigated and analyzed. In addition, field walk-through surveys and interviews were conducted in order to collect field data and to ascertain the field situation for the processes and industries. Results: A total of 10 cases of indium lung diseases have been reported in series since the first case reported in 2001. Seven cases were found in Japan, two cases in the United States, and one in China. No indium lung case has been reported yet in Korea, but it is believed that there are high potential risks among workers in indium-related industries. There are four categories in indiumrelated- industry; indium production and smelting, manufacturing of indium products such as ITO target, the production of thin films of flat panel display, and indium recovery industry. We found that all these types of industries are operating in Korea. Therefore, it is necessary for industrial hygienists to understand the processes and industries related to indium as well as the adverse health effects of indium. Conclusions: It was found that all four categories of indium-related industry from the indium production to recovery industry are active in Korea. However, the adverse health effects of indium are not well recognized. Therefore, it is believed that there is a high risks in indium-related industry, and it is necessary to make emergency interventions.
