Many universities are offering some of their offline courses for anyone to learn free online as an MOOC format. University libraries In response to changing university conditions, foreign university libraries are struggling to redefine their roles and provide new services. This study aimed to find the trends and models to support MOOCs in foreign libraries and Library and information science domain by conducting a systematic review of studies on foreign library and information journals which have been published from 2012 to 2015. A total of 34 out of 348 studies were included in the final analysis. This study also aimed to present the limits and the future models of MOOC support direction. The relevant articles could be identified, two criteria: 24 MOOCs studies relating to Libraries and 10 MOOCs studies related to LIS. The selected articles were summarized and analyzed yearly. The study identifies elements of library MOOC support models in 5 areas including MOOC design (copyright clearance and consulting, content licensing, open content), production support (course production, video editing, librarian MOOC production), management support (instructional design and content creation, students support), evaluation (MOOC data collection, analysis), reuse (MOOC metadata management, archive structure). Based on these findings, this study suggested the models of library MOOC support and set the theoretical fundamentals.

The aim of this study was to explore science teachers' perceptions of good science teaching. To this end, the Korean Teaching Observation Protocol (KTOP), which was developed for the purpose of observing and improving science teaching, was utilized. In the first survey, teachers were asked whether they thought each item in the KTOP was important for good science teaching, the extent to which they implemented these items, and the level of difficulty in implementing them. The second survey asked teachers what they believed to be the reasons and solutions for the KTOP items that they had responded as difficult to implement. The responses obtained from 63 teachers in the first survey and 35 teachers in the second survey were categorized based on the characteristics of the responses. The categorized contents were then summarized and discussed for their features. As a result, science teachers responded that all items in KTOP, except for one, are important for good science teaching. However, it was also shown that the level of execution was low in cases where implementation was difficult. For the 13 KTOP items that were considered important but difficult to implement and showed relatively low implementation level, many respondents (69%) attributed the reason to both students and teachers. However, the most common response (60%) was that the teacher should solve those difficulties. From this, it was found that understanding and supporting teachers, as well as enhancing their competencies, are more important for good science teaching than external factors. We hope that this research findings will help to better understand the specific difficulties that science teachers face in their classes and contribute to practical efforts that aim to address these challenges.

The purpose of this study was to provide information on adoptive families and obtain the basis data for adoption-related programs that are useful to adoptive families by examining their experiences in the adoption process, post-adoption adaptation, and adoption programs. For the study, in-depth interviews were conducted on six mothers who publicly adopted elementary school children and had expressed high satisfaction with adopted families and their willingness to participate in this research voluntarily. The main results exhibited parents' happiness post-adoption along with positive changes, such as internal growth, marital love growth, favorable response from others, and child's unexpected responses to adoption. However, open adoption mothers have coped with efforts to sympathize with and accept their children's feelings as they suffer from adoption, and with active support from their spouses, parents, and their own children. Open adoption mothers participated in various adoption-related programs, support, and voluntary self-help groups provided by adoption agencies or public organizations, and above all, their experience in self-help groups and peer groups of adopted children was found to be very useful. Based on these main results, we suggested strengthening welfare services for open adoption families, implementing education to better understand adoption, education for school teachers, students, and welfare staff, providing practical programs for adoptive families, and promoting self-help groups.

This study was conducted to find out the psychological or physiological healing effects of real natural forests and virtual forest experiences using virtual reality (VR) in an artificially-controlled digital environment. To find out this, 81 healthy undergraduate students from C University were experimented on visual forest stimulation effects in the digital environment from September 5 to December 9 in 2022. The experiment evaluated the psychological and physiological healing effects of visual forest stimulation in the digital forest environment (2D, 3D). The SRI (stress response inventory) experiment for analyzing psychological effect showed statistically significant differences among groups. As for the SRI experiment for measuring psychological stress, except Control group, 2D group in the digital environment showed little difference before and after the experiment. But 3D group showed less stress than before. As a result, it was proved that visual forest stimulation in a forest-based digital environment (2D, 3D) reduces psychological stress significantly. And when analyzing how visual forest stimulation changes EEG (electroencephalogram) in the digital environment, alpha waves (RA), which are activated during relaxation or stabilization, were more active than beta waves (RB), which are activated during tension or awakening. This study is expected to be used to create a psychological and physiological healing environment for those who cannot go to a natural forest due to mobility difficulties by providing them visual forest stimulation experiences in a digital environment. It is also expected that the results will be the basis for forest healing in the digital environment and virtual reality programs will help forest healing activities.

Internet companies that utilize social network have increased in number. The introduction of diverse social media services facilitated innovative changes in e-business. Social network service (SNS), which is a domain of social media, is a web-based service designed to strengthen human relations in the Internet and build new social relations. The remarkable growth of social network services and the profit generation and perception of this service are the new growth engines of this digital age. Given this development, many global IT companies views SNS as the most powerful form of social media. Thus, they invest efforts to develop business models using SNS.2) This study verifies the impact of privacy exposure in SNS as a result of privacy invasion. This study examines the purpose of using the SNS and user's awareness of the significance of personal information, which are key factors that affect self-disclosure of personal information. This study utilizes theory of reasoned action (TRA) to provide a theoretical platform that describes the specific behavior and emotional response of individuals. This study presents a research model that considers negative attitude (negatude). In this model, self-disclosure in SNS is considered a TRA. TRA is a subjective norm, a behavioral intention, and a key variable of exposure behavior. A survey was conducted on college students at Y university in Seoul to empirically verify the research model. The students have experiences in using SNS. A total of 198 samples were collected. Path analysis was applied to analyze the relations of factors. The results of path analysis show the statistically insignificant impact of privacy invasion on negatude, subjective norm, behavioral intention, and exposure behavior. The impact of unrecognized privacy invasion was also considered insignificant. The impacts of intention to use SNS on negatude, subjective norm, behavioral intention, and exposure behavior was significant. A significant impact was also found for the significance of personal information on subjective norm, behavioral intention, and exposure behavior, whereas the impact on negatude was insignificant. The impact of subjective norm on behavioral intention was significant. Lastly, the impact of behavioral intention on exposure behavior was insignificant. These findings are significant because the study examined the process of self-disclosure by integrating psychological and social factors based on theoretical discussion.

The aim of this study was to investigate upper and lower limb muscle activity using EMG(electromyogram) sensors while walking and identify normal gait pattern using FSR(force sensing resistor) sensor. Fifteen college students participated in this study and their EMG and FSR signal were measured during stopping and walking trials. EMG signals from upper(pectoralis major and trapezius) and lower limbs(rectus femoris, biceps femoris, vastus medialis, vastus lateralis, semimembranosus, semitendinosus, soleus, peroneus longus, gastrocnemius medialis, and gastrocnemius lateralis) were obtained using the surface electrodes. FSR measured pressures on 8 areas of the sole of the foot during walking. EMG results showed that all muscle activities except for vastus lateralis and semimembranosus during walking had higher amplitudes than stopping. Additionally, muscle activities associated with stance and swing phase during walking were identified. Results on FSR showed that stance and swing phases were detected by FSR signals during a gait cycle. Eight gait phases－initial contact, loading response, mid stance, terminal stance, pre swing, initial swing, mid swing, and terminal swing- were classified.

Hacking has raised many critical issues in the modern world, particularly because the size and cost of the damages caused by this disruptive activity have steadily increased. Accordingly, many significant studies have been conducted by behavioral scientists to understand hackers and their practices. Nonetheless, only qualitative methods, such as interviews, meta-studies, and media studies, have been employed in such studies because of hacker sampling limitations. Existing studies have determined that intrinsic motivation was the dominant factor influencing hackers, and that their techniques were mainly acquired from online hacking communities. However, such results have yet to be causally proven. This study attempted to identify the causal factors influencing the motivational and environmental factors encouraging hackers to learn hacking skills. To this end, hacker community members using the theory of planned behavior were observed to identify the causal factors of their learning of hacking skills. We selected a group of students who were developing their hacking skills. The survey was conducted over a two-week period in May 2015 with a total of 227 students as respondents. After list-wise deletion, 215 of the responses were deemed usable (94.7 percent). In summary, the hackers were aware that hacking skills are considered socially unethical, and their attitudes toward the learning of hacking skills were affected by both intrinsic and extrinsic motivations. In addition, the characteristics of the online hacking community affected their perceived behavioral control. This study introduced new concepts in the process of conducting a causal relationship analysis on a hacker sample. Moreover, this research expanded the discussion on the causal direction of subjective norms in unethical research, and empirically confirmed that both intrinsic and extrinsic motivations affect the learning of hacking skills. This study also made a practical contribution by raising the educational and policy response issues for ethical hackers and demonstrating the necessity to intensify the punishment for hacking.
