Oral history research is carried out through collecting information about a living person. The data collected from an oral history project is not a mere fact or a mass of information but accounts of persons who reveal their own personalities. For this reason, oral history research and data collection and the use of such data must be based on rigorous ethical standards. The Bioethics and Safety Law shares a similar view on human subject research, and the Institutional Review Boards includes human subject research as a subject of review and management. However, the Bioethics and Safety Law's protection of personalities and human rights focuses on life sciences methodologies, which are not suitable for qualitative research, such as an oral history of a value oriented and critical approach to human beings. This study examines the details of the Bioethics and Safety Law related to human subject research and the problems that may arise when this law is applied to subjects in humanities and social sciences such as oral history. Through this study, alternative methodologies, which can be used for oral history research, while maintaining academic autonomy, are suggested.

Background: Thymic stromal lymphopoietin (TSLP) acts as a master switch for inflammatory responses. Ginsenoside Rg3 (Rg3) which is an active ingredient of Panax ginseng Meyer (Araliaceae) is known to possess various therapeutic effects. However, a modulatory effect of Rg3 on TSLP expression in the inflammatory responses remains poorly understood. Methods: We investigated antiinflammatory effects of Rg3 on an in vitro model using HMC-1 cells stimulated by PMA plus calcium ionophore (PMACI), as well as an in vivo model using PMA-induced mouse ear edema. TSLP and vascular endothelial growth factor (VEGF) levels were detected using enzyme-linked immunosorbent assay or real-time PCR analysis. Murine double minute 2 (MDM2) and hypoxia-inducible factor 1α (HIF1α) expression levels were detected using Western blot analysis. Results: Rg3 treatment restrained the production and mRNA expression levels of TSLP and VEGF in activated HMC-1 cells. Rg3 down-regulated the MDM2 expression level increased by PMACI stimulation. The HIF1α expression level was also reduced by Rg3 in activated HMC-1 cells. In addition, Rg3-administered mice showed the decreased redness and ear thickness in PMA-irritated ear edema. Rg3 inhibited the TSLP and VEGF levels in the serum and ear tissue homogenate. Moreover, the MDM2 and HIF1α expression levels in the ear tissue homogenate were suppressed by Rg3. Conclusion: Taken together, the current study identifies new mechanistic evidence about MDM2/HIF1α pathway in the antiinflammatory effect of Rg3, providing a new effective therapeutic strategy for the treatment of skin inflammatory diseases.

This study utilizes the IPA (Importance-Performance Analysis) method to assess the importance, possibility, and urgency of using blockchain technology for fisheries sectors and the related policies. Based on a field survey targeting experts and stakeholders in the fisheries and blockchain technology sectors, the following major results and corresponding implications are drawn. First of all, the respondents of our survey have an outlook that the introduction and utilization of blockchain will be required in four major parts. These parts include i) the seafood' information system managed by the government or public institutions, ii) traceability and certification process for domestic and foreign seafoods, iii) meeting the need of seafood safety from consumers, and iv) taking prompt actions to seafood safety related accidents. Next, the seafood information system managed by the government or public institutions has been limited in maintaining information consistency and continuity once the fisheries ministries and departments are integrated, closed or partially transferred. Thus, it is assessed that the technology will be able to improve consistency and continuity of the seafood information in case of applying blockchain to the seafood information management system. This result that blockchain is necessary for the seafood information system have a significant implication in Korea's seafood management which has been independently controlled until now. Lastly, the application of blockchain to seafood traceability and certification systems has the most well-known cases through international and domestic pilot projects, and the results of our survey reflect this reality. Our results contribute to showing an additonal characteristics of blockchain in the fisheries sector, resulting in the possiblity that blockchain can be used for taking swift steps in the event of seafood safety accidents and meeting the need of seafood consumers for safety.

This study attempted to verify the impacts of the level of satisfaction in the user of alternative materials among people with visual impairment on their social participation, and the mediation effect of self-efficacy during such process. The subject of the study was the visually impaired who were live in Gyeonggi Province and were registered in the Korea Blind Union. The data of final 120 participants through a telephone survey were analyzed. The subject of the study used the recorded materials the most for the purpose of leisure and information research mainly at the braille library. The analysis of the mediation effect demonstrated that the level of satisfaction in the user of alternative materials among people with visual impairment had a statistically significant influence on social participation, and self-efficacy had a full mediation effect. These results imply the importance of alternative materials to assure the right to information access which can ultimately expand the social engagement of the visually impaired. Based on these study results, political suggestions are proposed to vitalize alternative materials in the future.

As many existing research fields are matured academically, researchers have encountered numbers of academic, social and other problems that cannot be addressed by internal knowledge and methodologies of existing disciplines. Earlier, pioneers of researchers thus are following a new paradigm that breaks the boundaries between the prior disciplines, fuses them and seeks new approaches. Moreover, developed countries including Korea are actively supporting and fostering the convergence research at the national level. Nevertheless, there is insufficient research to analyze convergence trends in national R&D support projects and what kind of content the projects mainly deal with. This study, therefore, collected and preprocessed the research proposal data of National Research Foundation of Korea, transforming the proposal documents to term-frequency matrices. Based on the matrices, this study derived detailed research topics through Latent Dirichlet Allocation, a kind of topic modeling algorithm. Next, this study identified the research topics each proposal mainly deals with, visualized the convergence relationships, and quantitatively analyze them. Specifically, this study analyzed the centralities of the detailed research topics to derive clues about the convergence of the near future, in addition to visualizing the convergence relationship and analyzing time-varying number of research proposals per each topic. The results of this study can provide specific insights on the research direction to researchers and monitor domestic convergence R&D trends by year.

Background: The purpose of this study is to explore the effects of daily mindfulness in parents with 3 to 5-year-old children on their stress and psychological well-being. Methods: Based on the previous studies, this study established a research model in which parent's mindfulness affects their psychological well-being by the mediation of stress, and verified the relationship between them using 283 parents data set. Results: First, mindfulness and psychological well-being in the ages of 40s was significantly higher than the 20s~30s. Second, parent's mindfulness and psychological well-being showed high positive correlation, and stress showed high negative correlation with mindfulness and psychological well-being. Third, it was verified that mindfulness not only directly affects psychological well-being but also indirectly influences psychological well-being by reducing their stress. Conclusions: This study suggests that daily mindfulness in parents with 3 to 5-year-old children is effective in managing their stress and improving their psychological well-Being.

The aim of this study is to analyze the current status and performance evaluation systems of faculty in Korean medical colleges and professional graduate medical schools (called medical schools). We developed a research tool based on previous studies and distributed it to 40 medical schools from July to October 2017. The response rate was 100%. We calculated the number of faculty members and analyzed the faculty evaluation systems and awareness according to national and private medical schools. As of 2017, the number of medical faculty in Korea was 11,111 (4,973 faculty were employed by their alma mater, which is 44.76% of the total), with non-medical doctor faculty accounting for 754 of the total. The medical schools reflect research achievements as most important for re-appointment and screening to promote faculty, and the area of education is secondary excepting clinical faculty of private medical schools. However, important issues in the faculty evaluation deal with the relevance of research achievement and the need for qualitative assessment. Some medical schools revised or have been revising the faculty evaluation system in areas such as minimum standards of education for promotion and separation of promotion and tenure review. Opening non-tenure track lines for faculty show positive effects such as increasing the number of positions for hire and easing the financial burdens of medical schools. Downfalls include inconsistencies between the responsibilities and actual practices of tenure not being available and the instability of faculty's status. In conclusion, medical schools need to prepare a faculty evaluation system that fits the position of faculty members and attempt to establish a reasonable compensation system.

Squid is a popular seafood in Korea. However, since the 2000s, the squid production has been declining. The unstable supply of the squid products may cause price fluctuations of fresh and chilled squid. These price fluctuations may be relatively more severe than them of other commodities, because the fresh and chilled squid can not be stored for a long period of time. Thus, this study analyzes the structural characteristics of price volatility and price asymmetry of fresh squid based on off-diagonal GARCH model. Data used to analysis of this study are daily wholesale and retail prices of fresh squid from January 1, 2006 to December 31, 2016 provided in the KAMIS. As theoretical approaches of this study, first of all, the stability of the time series is confirmed by the unit root test. Secondly, the causality between distribution channels is checked by the Granger causality test. Thirdly, the VAR model and the off-diagonal GARCH model are adopted to estimate asymmetry effect and price volatility spillover between distribution channels. Finally, the stability of the model is confirmed by multivariate Q-statistic and ARCH-LM test. In conclusion, fresh squid is found to have shock and volatility spillover between wholesale and retail prices as well as its own price. Also, volatility asymmetry effect is shown in own wholesale or retail price of fresh squid. Finally, this study shows that the decrease in the fresh squid retail price of t-1 period than the increase in the t-1 period has a greater impact on the volatility of the fresh squid wholesale price in t period.

Convergence education, which is operated by many engineering colleges, is mainly led by government-led projects. Convergence majors are established in consideration of the research field of the university professors rather than systematically analyzing the needs of the industry. The purpose of this study is to present the directions of convergence technology education related to new industry fields by analyzing industry needs. Participants were 299 industrial workers in various fields. Instrument consisted of three parts: necessity for convergence education, demand for convergence new technology education from industry perspective, and opinions about undergraduate convergence education. As a result, it was found that the level of awareness of industry needs for fusion technology education was high, and it was confirmed that there is a high demand for IoT convergence, bio-health, advanced new material, and renewable energy fields among convergence technology fields. In addition, the results of the industry demand for convergence new technology education were presented. The suggestions for expectations, problems, and improvements in undergraduate education were presented and implications for convergence technology education were discussed based on the results of the study.
