There are increasing numbers of North Korean defectors. Many of them enter universities and major in social welfare in order to get jobs. As a required course, they must participate in field practicum and many difficulties are expected. This study aims to examine the North Korean defectors' practicum experience in specific, and to support more effectively in the field work education. To achieve this purpose, female North Korean defectors who go to G cyber university and have finished their field practicums, were interviewed in an in-depth interview. The data were analyzed with the open coding through the constant comparison method as Grounded theory's initial analysis. As the result, the following was found: 49 concepts, 18 sub-categories, and 7 categories. The categories include difficulties in the process of preparation for and beginning with various obstacles; confusion due to the differences between the North Korean and South Korean culture; tasks and functions that were not expected, personal relationships which were burdensome to them; feeling a lack of professional competence; inevitable environmental circumstances, and personal problems. Based on the results, suggestions for better support in field practice education in the side of universities, community agencies, individual students and the general society were addressed.

Personal Air Vehicle (PAV), Cargo UAS (Cargo UAS), and existing manned and unmanned aircraft are key vehicles for urban air mobility (UAM), and should demonstrate compatibility for the design of aircraft systems. The safety assessment required by for certification to ensure safety and reliability should be systematically performed throughout the entire cycle from the beginning of the aircraft development process. However, with the increasing complexity of safety critical aviation systems and the application of state-of-the-art systems, conventional experience-based and procedural-based safety evaluation methods make ir difficult to objectively assess safety requirements and system safety. Therefore, Model-Based Safety Assessment (MBSA) using modeling and simulation techniques is actively being studied at domestic and foreign countries to address these problems. In this paper, we propose a Model-Based Safety Evaluation framework utilizing modeling and simulation-based integrated flight simulators. Our case studies on the Traffic Collision Availability System (TCAS) and Wheel Brake System (WBS) confirmed that they are practical for future safety assessments.

This study expects to understand Korean girls' weaknesses in science achievement and to make suggestions for improvement. The analyses of 95 released items in TIMSS 2003 show that Korean girls had few difficulties in 'inference and analysis', 'very hard or very easy' items, 'previously-learned' items, and items presented in context of 'school science'. They achieved lower in items of understanding science concept or factual knowledge. Inference and analysis items, which were favorable to girls, worked unfavorably to them as case science knowledge intervened. Girls outperformed boys in items with 80% or more and with 20% or less percent correct. Also, the boys showed much higher achievement in previously learned and contextualized items, which proves girls' lack of interest in science in everyday life. On the base of item analysis, several suggestions were made for the girl-inclusive science education in Korea: First, girls should have more opportunities for science experience not only in school context but also in everyday life. Second, more teaching and learning programs should be developed to care girls' weaknesses in science learning. Lastly, gender issues in science education should be actively included in curriculum development process and teacher training programs.

This study empirically analyzes the relationships among the road and traffic experts' personal characteristics, the driving behavior and factors being expected to have an effect on the satisfaction about roundabout operation. The factors are drawn and grouped through the principle component analysis to clarify driving environment satisfaction on roundabout operation. Each group is named as personal attribute, driving behavior attribute, and satisfaction. After the variables are refined by confirmatory factor analysis, satisfaction model is developed with personal attribute and driving behavior attributes as exogenous variables and roundabout driving awareness and emotion attributes as endogenous variables. As a result, driving satisfaction of roundabout operation is directly influenced by delay reduction, safety improvement, capacity increase, sight improvement, severity accident reduction, and bicycle convenience and indirectly gender, age, driving time, and driving experience. Law obeyance, driving concession, traffic sign obeyance, and interposition do not statistically shows significant on satisfaction. As a result of Analytical Hierarchy Process (AHP), the turning radius of geometry and the driving behavior are important elements for roundabout safety.

Northeast Asia including China, Japan, Mongolia, Russia, DPRK and ROK, is a geographically close region that falls under the same environmental influence. Recently the region is not only facing serious domestic environmental problems with rapid economic growth, but also confronted with transboundary environmental problems and associated conflicts between countries. Unfortunately, Northeast Asia lacks a solid environmental management system among countries to deal with transboundary and other environmental issues. Transboundary Environmental Impact Assessment (TEIA) can, therefore, be one of the essential systematic measures in which environmental problems between countries would be negotiated. However, it would be necessary to have an indepth discussion of what we have to do first for implementing TEIA system in the region, and how to operate it while customizing each Northeast Asian country with different EIA system and socioeconomic circumstance. All these cannot be decided in a short time, and we need to invest enough time for discussing and considering them from various aspects. Recently, the Korean government declared "Eurasia Initiative". The initiative proposes important developing projects and ultimately plans to build a peaceful community throughout Eurasia based on comprehensive cooperation. The initiative aims to increase exchanges in transportation, energy and agricultural sectors to achieve the goals. In this regard, implementing TEIA in Northeast Asia is urgently needed and we have to prepare the strategy for introducing TEIA mechanism. Based on the results of 10 year experience on TEIA projects conducted since 2004, we suggest double-track approaches for developing TEIA mechanism. We continuously need to make an effort to establish a regional TEIA mechanism that all countries legally join, and simultaneously we also have to prepare a process to carry out TEIA for upcoming projects based on bi- or multi-lateral agreements. Practical solutions such as conducting pilot TEIA with relevant countries and developing TEIA guideline for the region could be the first step.

This research provides a quantitative analysis on research articles published in PLoS ONE, a multidisciplinary open access journal, by authors affiliated with Korean institutions. Korean authors published more than 6,500 research ariticles in the mega journal between 2006 and 2019. Korea is ranked the top 11th place in terms of article publishing in the journal. Most articles by Korean authors are concentrated in the biomedical fields. In recent years, the overall production of PLoS ONE has decreased as authors migrated to competing mega journals such as Scientific Reports and BMJ Open. The change might have been affected in part by the delay in the review period and the dropping impact factor score. The open access share of the Korean PLoS ONE authors of more than 10 articles hovers around 30%. However, there is a significant variation among researchers reaching up to 50% discrepancies. Among altmetrics provided by PLoS ONE, the saves are highly correlated with the views and the citations. On the contrary, the shares show low correlation with other use metrics. A follow up, survey questionnarie based research involving researchers who have published in PLoS ONE is planned in order to investigate author motivation and experience in the review process.
