Whilst Ecological momentary assessment (EMA) can provide important insights over time and across contexts among rotation workers whose work periods alternate with leave at home, it can also be challenging to implement in the resources and construction sectors. This review aimed to provide a summary of the methodological characteristics of EMA studies assessing health outcomes and related behaviors in rotation workers. Systematic searches in PubMed, Medline, EMBASE, CINAHL, PsycINFO, and Scopus were done to include 23 studies using EMA methods in assessing health-related outcomes and behaviors. EMA designs included daily diary: assessments once per day typically fixed at the end of day (47.8%), within day fixed interval time-based design: assessments on multiple times per day at certain times of day (17.4%) and combination of both designs (34.8%). Studies employed paper and pencil diaries (73.9%) and one or more electronic methods (60.9%): wrist-worn actigraphy device (52.2%) and online-based diaries (26.1%) for data collection. Most of the studies (91.3%) did not report prompting -EMAs by schedule alerts or compliance. Daily diary and within day fixed interval dairies designs are common, with the increasing use of electronic EMA delivery techniques. It is unclear how well participants adhere to assessment schedules, as these are inadequately reported. Researchers should report compliance-related information.

Purpose: The purpose of this study is to investigate the mediator effect of major satisfaction in relation to depression and job-seeking stress of university students according to the majors. Methods: This descriptive study was conducted in three universities randomly chosen from 47 universities in Seoul, Korea. Participants were 241 undergraduate students who were eligible and agreed to participate in the study. Data were collected from October 27 to November 10, 2014. The data were analyzed with descriptive statistics, $x^2$ test, Fisher's exact test, t-test, Kruskal-Wallis test, Pearson correlation coefficients, simple and multiple regression techniques with the PASW/WIN 20.0 program. Results: There were significant negative, negative, and positive correlations between job-seeking stress and major satisfaction, major satisfaction and depression, and job-seeking stress and depression regardless of major field, respectively. Moreover, in the major group in natural science and engineering, the link between job-seeking stress and depression was partially mediated by major satisfaction. Conclusion: The findings of this study contribute to providing basic data for the development of job-seeking stress and depression intervention programs and future study for university students.

Purpose: The internet, as a tool, avenue, and field, has wide-researching and specific ethical concerns. Internet-based research ethics is a field that spreads across numerous fields, scoping from natural and biomedical sciences to social sciences, and arts and humanities. Thus, this study which investigates research ethics within an Internet-based Research Setting will be quite valuable. Research design, data and methodology: The current authors widely took a look at prior and present literature dataset to explore research ethics within an Internet-based setting. Using numerous search engine, such as 'Goole Scholar', 'Scopus', and 'Web of Science', the current authors could obtain total 42 prior studies that are relevant with our research topic. Results: Based on the screening process in the literature datasets, this study could categorize four areas of the research ethics within Internet-based research setting as follows: (1) Human Subjects Ethics, (2) Big Data Ethical Issues, (3) Research Ethics and Cloud, and (4) Computing Interviews and Surveys Ethics. Conclusions: This study concludes that although internet-based research has many benefits, the accompanying ethical issues are many. The lack of uniformity in the concept and terminology of online research methods typically brings forth confusion and makes it hard for new researchers to develop mutual guidelines.

The study purported to develop STS education course material at the university level in order to enhance science literacy and understanding of the relationships among science, technology and society. A developed STS course was provided to 265 freshmen and sophomore students, majoring in the Humanities and the Social Sciences, the Natural Sciences and Engineering, and Fine Arts. Students participated in the survey examining changes in students' attitudes toward and perspectives on STS before and after the implementation. Ten questionnaires were selected from VOSTS for the survey. One additional questionnaire asked the students to elaborate their opinions on the need for a STS education course. The responses to the survey were analyzed according to types of questions and students' majors. As result, the developed STS course significantly increased students' science literacy. Among the participants, 97.7% responded that there is a need for STS education and provided reasons for such need. These results imply that there is a definite need for a STS class at the university level. According to the analyses of responses, there were different responses depending on the students' major. These differences imply that the major, academic background, level of interest in science, and knowledge of science of the students affect their perceptions on identifying the need for a STS education course.

In recent years, 'technological fusion or convergence' has drawn a lot of attention of innovation researchers and governmental policy makers as the driving force of technological innovation and industrial growth. There are, however, few studies on the analysis of longitudinal trends of technological convergence and its comparison between global and national level. In this study, with the citation data of about 18 million articles, we analyzed 1) the growth of representative convergence research areas, 2) the convergence of citing patterns between research fields, and 3) the changing trend of diversity index of all research fields. We conclude that technological convergence in korea shows the relatively strong orientation to the combination of neighboring fields than that of heterogenous fields in comparison to global trend. In particular, the relatively weak activity of cognitive science and the low level of mutual exchange between arts/humanities/social sciences and natural/engineering sciences in Korea are emphasized.

This study is an attempt at developing an organizational model for collection development a n.0, pplicable to Korean university libraries at their present stage of development. An emphasis is placed on the discussion of the 'subject a n.0, pproach' as compared to 'functional a n.0, pproach' in collection development work. The case history of Pusan National University Library is extensively used. The proposed collection development model consists of the following elements : - To form a collection development team and to place under the team leader subject bibliographers as follows: Bibliographer for Serials Bibliographer for Humanities Bibliographer for Social Sciences Bibliographer for Sciences and Technologies - Collection development team could operate as a separate department or as part of other departments, i. e., Deputy Director's office, Acquisitions and Processing Department, or Resources Management Department. - Collection development team takes up the responsibility for policyrelated collection work, i. e., budget allocation, evaluation of existing collection, building core collection, preservation, weeding and cooperation. - Designated certified librarians located at the(planned) subject libraries take up the responsibility for selection. Subject bibliographers cooperate with selection librarians and coordinate their work. - Certified librarians at the Acquisitions and Processing Department are assigned subject areas. They operate as acquisitions librarian and processing librarian simultaneously with their assigned subject materials.

Clearly, the smartphone is increasingly playing a greater role in everyday life, thus providing opportunities to evaluate how well the use of the smartphone meets the requirements of undergraduate students in independent learning outside of a classroom setting. This study used the task-technology fit (TTF) model to explore the effectiveness of smartphone usage to interact with learning materials in independent learning outside of classrooms, the need for smartphone support, and the fit of devices to tasks as well as performance. First, the study used interviews, observation, and survey data to identify what are the most important constructs of smartphones that stimulate students to interact with learning materials in independent learning outside of classrooms. Based on the findings from the exploratory study and Task Technology Fit theory, we postulated the Navigation design, Ergonomic design, Content support, and Capacity as the essential dimension of the smartphone construct. Then, we proposed a research model and empirically tested hypotheses with the structural model analysis. The results reveal a significant positive impact of task and technology on TTF for smartphone usage to interact with learning materials in independent learning outside of classrooms; it also confirmed the TTF and performance have a direct effect on actual use.

This study examines the dynamic pattern of the exchange rate volatilities of the ASEAN-5 currencies from January 2006 to August 2020. The exchange rates applied in this study comprise bilateral and effective exchange rates in order to investigate the influence of the US dollar on the stability of the ASEAN-5 currencies. Since a volatility model employed in this study is a natural cubic spline volatility model, the Monte Carlo simulation is consequently conducted to determine an appropriate criterion to select a number of quantile knots for this model. The simulation results reveal that, among four candidate criteria, Generalized Cross-Validation is a suitable criterion for modeling the ASEAN-5 exchange rate volatilities. The estimated volatilities showed the inconstant dynamic patterns reflecting the uncertain exchange rate risk arising in international transactions. The bilateral exchange rate volatilities of the ASEAN-5 currencies to the US dollar are more variable than their corresponding effective exchange rate volatilities, indicating the influence of the US dollar on the stability of the ASEAN-5 currencies. The findings of this study suggest that the natural cubic spline volatility model with the quantile knots selected by Generalized Cross-Validation is practical and can be used to examine the dynamic patterns of the financial volatility.
