Design-Based Research (DBR) focuses on developing key principles of interventions to advance both theory and practicalities of dissemination (Brown, 1992), yet its methodological details have not been quite established. Thus, the purpose of this paper is to address the pragmatics of DBR by sharing the researcher's reflections on conducting a longitudinal DBR project for five years. In an attempt to advance college teaching practices as well as theories related to student plagiarism, the project focused on refining "humble" theories on how and why college students engage in plagiarism to design classroom interventions for promoting academic integrity. Similar to the Integrative Learning Design (ILD) framework proposed by Bannan-Ritland (2003), but conducted in a much simpler and less formal format, this study followed DBR cycles from initial conceptualization to design and enact instructional interventions in authentic contexts while collecting both quantitative and qualitative data from each phase. Finally, the paper addresses some challenges encountered throughout the DBR project as well as the lessons learned from this experience. Like many previous DBR studies whose practical relevance is limited to local context, the findings from this study may not be easily generalized for other contexts.

In spite that spatial ability has been recognized as an important element of academic achievement in engineering studies, researches on the topic are rather limited in Korea. In this study, the relationship between spatial visualization skill and academic achievement of engineering students was investigated based on the several variables such as gender, high school education background and college course achievement. The result showed that there were significant relevance between spatial visualization skill and gender, high school type, achievement of high school level math & physics, and college course work grade of computer graphic and capstone design. According the case study, from the entry time of engineering college, support programs to reinforce spatial visualization skill are required for lower skill groups such as female and graduate from art course in high school. Also, college curriculum such as Engineering graphics, Capstone design are substantial to improve spatial visualization skill. However, more diversified sample groups and research methods are required in order to draw in depth results.

Mobile computing devices (MCDs), such as smartphones and tablets, are revolutionizing medical practice. These devices are almost universally available and offer a multitude of capabilities, including online features, streaming capabilities, high-quality cameras, and numerous applications. Within the surgical field, MCDs are increasingly being used for simulations. Microsurgery is an expanding field of surgery that presents unique challenges to both trainees and trainers. Simulation-based training and assessment in microsurgery currently play an integral role in the preparation of trainee surgeons in a safe and informative environment. MCDs address these challenges in a novel way by providing valuable adjuncts to microsurgical training, assessment, and clinical practice through low-cost, effective, and widely accessible solutions. Herein, we present a review of the capabilities, accessibility, and relevance of MCDs for technical skills acquisition, training, and clinical microsurgery practice, and consider the possibility of their wider use in the future of microsurgical training and education.

The purpose of this study is to classify the types of local market knowledge and knowledge sources in reverse knowledge transfer and analyze their relevance. To do so, first, we searched for papers related to the types of local knowledge published in 9 international business academic journals between 1988 and 2020, and derived four types of local market knowledge. Second, in order to classify the source of knowledge, we searched for papers related to network types published in 9 international business academic journals between 1988 and 2020, and divided them into 4 types to derive characteristics. Third, by examining the types of local market knowledge that can be obtained according to network types, a conceptual model was developed between them, and the suitability between local market knowledge and sources of knowledge was revealed through empirical analysis. Through empirical research on what kind of knowledge can be obtained depending on the knowledge sources, various business and academic implications can be provided to many companies.

PURPOSE: This study was conducted to understand the adaptive responses of different modes of physical exercises utilizing skeletal muscle and the comprehensive relevance of AMPK signaling that can be activated by physical exercise as a potential molecular target in human health problems such as neuromuscular disorders (NMDs). METHODS: Most of the contents in this review article are based on recent publications concerning the main topics of interest. The reference literatures cited were obtained by basic searches of overseas academic databases such as PubMed and ScienceDirect using EndNote X7.8. RESULTS: The phenotypic adaptive responses of skeletal muscle during endurance- and resistance-based exercise training (ET and RT respectively) appear to be distinct. To explain the adaptive responses in each single mode of exercises (ET, RT) along with combined exercise training (CT), AMPK signaling is proposed as an important molecular link among those differential modes of exercise and a promising molecular target of NMDs. CONCLUSION: Based on the available evidence, intracellular AMPK signaling activated by diverse stimuli including physical exercise can be a potential and promising therapeutic target for the prevention, amelioration or cure of various human health problems including NMDs and may also be beneficial for physical rehabilitation and emergency situations that may elicit acute metabolic stresses.

The relevance between organisms and their external environment covers everything including humans, natural and artificial surroundings, regarding which academic and scientific understanding has continued. Relevant elements established by inter-dependence between humans and environment and the unity of life should be translated from the perspective of a whole, not of unit elements or reduction. That is, a space is formed by its own program and assumes sustainable relevance based on interactions between internal and external spaces, not building an independent system. The present study aims to present the feasibility of a potential mutant space formed by invisible arenas between individuals and evolutionary space formation based on an ecological paradigm Accordingly, this study suggested that evolutionary attributes as the major power source of biological changes could verify the virtual multiplicity of a new space formation, and that the potential form generation of hybrid mutant space of emergence and infinite formative capability could be supported. The suggestions made here will hopefully contribute to extending applicability of evolutionary space generation in the field of space design. To derive the potential mutant forms from biological space, a preliminary study was conducted regarding the characteristics of evolutionary form generation. For the purpose of this study, three evolutionary perspectives of reproduction, mutation (variation) and selection were taken. First, the theory of evolution was defined and characterized. Also, the relevance between the characteristics generated and hybrid mutant space was analyzed to consider relevant characteristics. The present study helped to understand that the hybrid mutant space had an evolutionary space structure based on a biological paradigm. It was also found that the mutant space structure built by mutant polymorphism assumed a systematic correlation between space and environment.

This study aims to analyze and evaluate term suggestion services of major search portals, Naver and Google Korea. In particular, this study evaluated relevance and currency of related search terms provided, and analyzed characteristics such as number and distribution of terms, and queries that did not produce terms. This study also analyzed types of terms in terms of the relationship between queries and terms, and investigated types and characteristics of harmful terms and terms with grammatical errors. Finally, Korean queries and English queries, and popular queries and academic queries were compared in terms of the amount and relevance of search terms provided. The results of this study show that the relevance and currency of Naver's related search terms are somewhat higher than those of Google. Both Naver and Google tend to add terms to or delete terms from original queries, and provide identical search terms or synonym terms rather than providing entirely new search terms. The results of this study can be implemented to the portal's effective development of term suggestion services.

Purpose As the number of SNS users increases, the importance of SNS advertisement is also increasing. Thus, the purpose of this study is to analyze the effect of factors on effectiveness of SNS advertising, and expand research on users' attitude and behavior intention toward SNS advertising. Design/methodology/approach This study was designed to examine the structural relationships among SNS service attribute, users' cognitive characters, psychological factors, users' attitude and behavior intention toward SNS advertising. Concretely, SNS service attribute was presented as online interactivity, and users' cognitive characters were presented as perceived relevance and perceived intrusiveness. In addition, psychological factors were presented as presence experience and message credibility, users' attitude toward SNS advertising was presented as advertisement attitude and users' behavior intention was presented as WOM. Findings The results showed that online interactivity has a positive effect on presence experience and message credibility, but perceived intrusiveness has a negative effect on presence experience and message credibility. Perceived relevance has a positive effect on presence experience, but does not have significant effect on message credibility. Presence experience and message credibility have positive effects on advertisement attitude and WOM, and advertisement attitude also has a positive effect on WOM. Based on the results from this study, academic and practical implications can be drawn. First, the study extended the scope of research about SNS advertising through focusing on SNS service attribute and SNS users' cognitive characters and identified the relationship between presence experience, message credibility, advertisement attitude and WOM. Second, the results of this research can provide practical guidelines to develop effective advertising strategies for companies which promoting SNS as a marketing tool.

Purpose: This study was performed to investigate the level of ethical values and its related factors among some paramedic students. Methods: The subjects of this study were 480 paramedic students from five universities located in G-metropolitan city and J province. Data were collected using a self-administered questionnaire and analyzed using t-test, ANOVA, Pearson's correlations, and multiple regression analysis. Results: The mean scores of level of ethical values, academic self-efficacy and self-esteem were $3.70{\pm}0.45$, $3.15{\pm}0.42$ and $3.60{\pm}0.70$, respectively. In the correlation analysis, ethical value level was significantly positively correlated with self-esteem (r=.195, p< .001) and academic self-efficacy (r=.156, p= .001), of domains in academic self-efficacy, self-regulation efficacy (r=.230, p< .001) and confidence (r=.105, p= .022). In multiple regression analysis, self-esteem (${\beta}=.163$, p= .026), task ease preferences (${\beta}=-.350$, p< .001) and confidence (${\beta}=.403$, p< .001) were significantly related to ethical value levels. In addition, subjects willing to participate in the bioethics education showed higher relevance to ethical values than indifferent subjects (${\beta}=2.751$, p= .003). Conclusion: Concrete and systematic education will be needed in order to foster the establishment of ethical values of the paramedic students. Additionally, to fulfill their roles and obligations as emergency medical technicians, in the field, various educational curricula based on simulated cases in the university should be introduced.

Purpose: This study was a descriptive study to identify factors affecting the attitude toward life-sustaining treatment of nurses working at long-term care hospitals. Methods: Data were collected through structured questionnaires from August 2nd to 27th, 2019. Study participants consisted of 163 nurses who were working for at least 6 months from 7 long-term care hospitals in B and K city. Data were analyzed using t-test, ANOVA, Scheffe' test, Pearson's correlation coefficients, and hierarchical regression with SPSS WIN v 21.0. Results: There were significantly positive correlations between awareness of good death (r=.46, p<.001) and perception of patients' rights (r=.32, p<.001). The factors affecting participants' attitude toward life-sustaining treatment were awareness of good death (β=.35, p<.001) and their own view of death (β=.24, p=.001), which explained about 27.0% of the attitude toward life-sustaining treatment. Conclusion: Based on these results, it is necessary to develop nursing educational materials that can establish values for deaths, and cultivate legal and ethical knowledge related to attitude toward life-sustaining treatment. In addition, since the severity of a patient's condition varies and the characteristics of the institution vary depending on the type of hospital, a study is needed on the relevance of variables considering the hospital environment.
