Teaching with technology has been widespread in practical classroom settings, and increased the needs to enhance pre-service teachers' capability with a variety of technologies. The purpose of this study is focused on designing and implementing a training program to develop pre-service teachers' Technological Pedagogical Content Knowledge(TPACK) which promotes them use technologies tactically in integrated science classes. Based on the theoretical framework of TPACK and Practitioner's Guide to TPACK, the authors developed ten periods of lessons comprised instructional skills in elementary science education. Subsequently, the program was applied into a teacher trainee course in Korea. The results of this study indicate that the TPACK training program for pre-service teachers significantly influenced on attitude toward convergence, TPACK, and science teaching efficacy of the engaged participants. The developed program, meanwhile, caused a significant TPACK improvement of female participants of the teachers college more effectively. Furthermore, it mitigated the gap between science and humanity tracks coming from their high schools. Consequently, there are possibilities to improve pre-service teachers' teaching strategies for integrated classes, if they have opportunities to review the comprehensibility of technological, pedagogical, content knowledge, and intersected areas with metacognitive perspectives.

This study attempted to identify the experiences of nursing students' participation in cadaver practice and provide a basis for understanding students' experiences in cadaver practice, which can be reflected in the development of programs for them. By applying the content analysis method according to the guidelines by Krippendorff to analyze the meaning of the experience of participating in cadaver practice among 80 nursing students who participated in cadaver practice at K University in W-si, Gangwon-do, a total of 4 areas, 13 categories, and 25 meaningful statements were derived. The categories included "worried," "surprised," and "fear" in the anxiety domain; "interesting," "knowing," and "focused" in the immersion domain; "value of life," "gratitude and remembrance," "thinking about donation," "facing death," and "precious body" in the reflection domain; and "motivation" and "sense of accomplishment" in the growth domain. The results of this study will help to understand the physical and psychological reactions that nursing students may experience during cadaver practice, and will provide a basis for developing various strategies such as counseling, education, and reflection programs in conjunction with cadaver practice to help nursing students cope with stress, develop a sense of ethical responsibility, and develop a positive self-image as nursing students in order to be successful in cadaver practice. This study is also significant because it provides a basis for preventive program interventions for experiences related to the negative effects of cadaver practice.

This study investigates and analyzes various marketing models that can overcome the economic challenges and resource scarcity faced by solo entrepreneurs. Previous research primarily focused on the integrated marketing communication (IMC) model, resulting in a lack of comprehensive discussion. In this study, we emphasized the IT content marketing communication model, considering a holistic analysis and the changing roles over time. As a result, we were able to propose a new strategic approach by integrating the ICM community model into a convergent value chain, improving the IMC model and promoting brand growth and online presence enhancement. This has laid the foundation for effectively increasing brand awareness and provided specific guidelines to support the sustained growth of solo entrepreneurship.

The purpose of this study is to analyze and evaluate the nature, role and development of pedagogical content knowledge in science teaching. Two research questions were considered: 1) What are the nature and the components of the pedagogical content knowledge in science teaching? 2) What is the value of pedagogical content knowledge and are there any routes and paths to developing pedagogical content knowledge for science teachers? In order to answer these questions instead of analyzing empirical data, former research literatures are reviewed. The results indicate that science pedagogical content knowledge is a special amalgam of science content knowledge and science method knowledge in a special context of science teaching that is uniquely the province of teacher based on their own special form of professional understanding. As a part of one's own distinctive bodies of knowledge, science teachers' pedagogical content knowledge is an important basis for professional development and competent teachers. It is knowledge of how to teach specific content in specific contexts, also it depends on each teachers' distinctive knowledge structure. Pedagogical content knowledge for science teaching is composed of five components: orientations toward science teaching, knowledge and beliefs about science curriculum, knowledge and beliefs about students' understanding of specific topics, knowledge and beliefs about assessment for teaching science, knowledge and beliefs about instructional strategies for teaching science. The development of science pedagogical content knowledge does not start until teachers have acquired a deeply principled conceptual knowledge of content, also it is promoted by the constant use of subject matter knowledge in teaching situations.

Purpose: With a rapid advance of communication technology, distributional systems of sport contents continue to show improvements. In particular, a traditional framework in creating sport cartoon has been influenced by the environment of the communication industry. Despite the development of distributional systems, the current sport cartoon industry still lacks in advancement. To this day, various research about sport contents have been conducted; yet, not many studies of the interaction between sport cartoons and communication technology have been done. In this respect, this study is to review the distributional environment of the sport cartoon industry and provide distributional strategies for developing sport cartoon industry. Research design, data, and methodology: In addition to in-depth interviews with five practitioners in sport cartoon industry, the study employed case study methodology. Interview data were analyzed by qualitative content analysis. Results: With new environments allowing anyone allowing to create and share webtoons, various genres including sports webtoons appear, and this became amotive to the growth of sports webtoons. Today, sports comics acted as a sports advertisement platform which not only created additional profit but also became an opportunity as a marketing method. On the contrary, the formal attributes of webtoons cause hardship in consistently creating sports webtoons. Hence, it is needed that supporting policies need to be established to nurture sport webtoon expertise. For example, Korea Creative Content Agency allows future webtoon authors to have an opportunity to be educated and equipped in producing creative sport webtoon contents. Moreover, revenue systems should be developed for motivating webtoon authors to involve in sport contents in their works. Conclusions: In order to promote the sports cartoon industry based on the findings, it is first necessary to create sports comics that reflect the formal characteristics of webtoons and the changing consumer environment. Second, it is important to acknowledge the industrial value of sports comics and it is necessary to promote policies regarding sports webtoon production and distribution from a national level. Third, by diversifying profits through OSMU and sports advertisements, it is possible to enhance the work environment and the treatment of authors. Implications and future directions were discussed.

Because the role of the teacher is important for the education to actualize the goals of the curriculum, the interest about the teacher's knowledges has been addressed as an important research topic. Among them, the pedagogical content knowledge is the knowledge that can emphasize the professionalism of the teacher. In this study, I analyzed the elementary pre-service teachers' the problem solving strategies that they imagined the methods that elementary school students can think about fraction division. Pre-service teachers who participated in this study were completed all of the mathematics education courses in the pre-service teachers' education courses. The research was conducted using the four type-problems of fraction division. The results showed that elementary pre-service teachers responded in the order of equal sharing problem-measurement division-partitive division-context of determination of a unit rate problem. They presented significant responses not only with typical algorithms but also with pictures or expressions. On the basis of this research, we have to take an interest in the necessity of sharing and recognizing various methods of fraction division in pre-service teachers education.

Video streaming over wireless networks is challenging due to node mobility and high channel error rate. In this paper, we propose a multi-source video streaming (MUVIS) system to support high quality video streaming service over IEEE 802.1l-based wireless networks. We begin by collocating a streaming proxy with the wireless access point to help leverage both the media server and peers in the WLAN. By tracking the peer mobility patterns and performing content discovery among peers, we construct a multi-source sender group and stream video using a rate-distortion optimized scheme. We formulate such a multi-source streaming scenario as a combinatorial packet scheduling problem and introduce the concept of asynchronous clocks to decouple the problem into three steps. First, we decide the membership of the multisource sender group based on the mobility pattern tracking, available video content in each peer and the bandwidth each peer allocates to the multi-source streaming service. Then, we select one sender from the sender group in each optimization instance using asynchronous clocks. Finally, we apply the point-to-point rate-distortion optimization framework between the selected sender-receiver pair. In addition, we implement two different caching strategies, simple caching simple fetching (SCSF) and distortion minimized smart caching (DMSC), in the proxy to investigate the effect of caching on the streaming performance. To design more realistic simulation models, we use the empirical results from corporate wireless networks to generate node mobility. Simulation results show that our proposed multi-source streaming scheme has better performance than the traditional server-only streaming scheme and that proxy-based caching can potentially improve video streaming performance.
