This study attempts to apply process drama in teaching Korean speaking. For that goal, the first part of the study introduces the main features of process drama exploring the possible use of teaching Korean speaking, and the second part presents a concrete example of developing a unit of the Sejong intermediate Korean conversation coursebook which was designed using a process drama method. Process drama is a process-oriented drama activity which progresses only with the teacher and students' spontaneous participation. With its unique meaning-oriented interaction paradigm, it has been suggested as an effective way of teaching and learning a foreign language. Since it emphasizes students' spontaneity, cooperation, and authentic communication, it commonly provides plenty of opportunities for students to interact in a meaningful context. Despite its effectiveness in teaching speaking, it has rarely been used in KFL contexts. Considering the limited opportunities to practice speaking in KFL classrooms, using a communication-rich activity such as process drama would be an optimal solution. This study, therefore, examines possible application of process drama in teaching Korean speaking, and introduces sample speaking materials designed for KFL intermediate learners.

Sarcomas are rare and heterogeneous mesenchymal neoplasms originating from the bone or soft tissues, which pose significant treatment challenges. The current standard treatment for sarcomas consists of surgical resection, often combined with chemo- and radiotherapy; however, local recurrence and metastasis remain significant concerns. Although immunotherapy has demonstrated promise in improving long-term survival rates for certain cancers, sarcomas are generally considered to be relatively less immunogenic than other tumors, presenting substantial challenges for effective immunotherapy. In this review, we examine the possible opportunities for sarcoma immunotherapy, noting cancer testis antigens expressed in sarcomas. We then cover the current status of immunotherapies in sarcomas, including progress in cancer vaccines, immune checkpoint inhibitors, and adoptive cellular therapy and their potential in combating these tumors. Furthermore, we discuss the limitations of immunotherapies in sarcomas, including a low tumor mutation burden and immunosuppressive tumor microenvironment, and explore potential strategies to tackle the immunosuppressive barriers in therapeutic interventions, shedding light on the development of effective and personalized treatments for sarcomas. Overall, this review provides a comprehensive overview of the current status and potential of immunotherapies in sarcoma treatment, highlighting the challenges and opportunities for developing effective therapies to improve the outcomes of patients with these rare malignancies.

Objectives: The purposes of this study was to describe workers' perceived values and the affecting factors (pros and cons) of the experience education for occupational safety and health and to suggest the strategies and future directions to improve the experience educational quality. Methods: A total of 8 male workers taking the safety and health education of the 7 safety experience education centers involved in this study (5 centers managed by Korea Occupational Safety and Health Agency (KOSHA), 2 centers of large commercial companies). This study used Photovoice, a qualitative method, as the study method. We conducted the photovoice-based in-depth interview with the SHOWeD questions and strategy and used the taxonomical analysis. Results: The study participants' perceived values of experience education were strengthening self-efficacy of the safety and health practices, providing practically useful information, and enjoying refreshing experiences different from daily jobs. Positive affecting factors of the experience education (pros) were providing the educational environments and opportunities of direct experiences, teaching practical safety and health contents for the participants, and the trainer's instruction competencies. Negative affecting factors of the experience education (cons) were learner's negative or standing postures during trainer's lecturing, insufficient exercise conditions and facilities for education, and difficult and theory-oriented lecture far from the practical jobs in reality. Conclusions: Major values of exercise education were direct experiences, useful contents and interesting opportunities from the education participants' perspectives. To improve the exercise education quality, overall educational environments such as convenience facilities as well as exercise facilities should be modified altogether. This study partially and conveniently used the photovoice method as the study limitation.

Even though algorithms for watermark embedding and extraction step are important issue for digital watermarking, watermark selection and post-processing can give us an opportunity to improve our algorithms and achieve higher performance. For this reason, we summarized the possibilities of improvements for digital watermarking by referring to the watermark merging techniques rather than embedding and extraction algorithms in this paper. We chose Cox's function as main embedding and extraction algorithm, and multiple barcode watermarks as a watermark. Each bit of the multiple copies of barcode watermark was embedded into a gray-scale image with Cox's embedding function. After extracting the numbers of watermark, we applied the watermark merging techniques; including the simple merging, N-step iterated merging, recover merging and combination of iterated-recover merging. Main consequence of our paper was the fact of finding out how multiple barcode watermarks and merging techniques can give us opportunities to improve the performance of algorithm.

The enhancement of the quality of the teaching practice is a major factor in securing better schooling opportunities for students. In this article, initial teacher preparation of secondary school Earth science teachers, in-service science teacher education, and improving teacher policy are discussed. Data from in-depth interviews with exemplary science teachers were used to explore how to improve the quality of science teacher education in Korea. In terms of preservice teacher education, most exemplary teachers contended that teacher education programs should provide preservice teachers with practical knowledge by translating theory into practice. Their suggestions for how to improve in-service education are also discussed. Regarding directions of improving teacher policy in Korea, the teachers proposed an alternative teacher-promotion structure that incorporates the master-teacher position. Implications for introducing action research courses into teacher (re)education programs are also discussed.

Non-volatile RAM (NVRAM) provides many opportunities to improve the performance of computing devices. In this paper, we present an approach that reduces the user-perceived latency of browsers by using NVRAM. To this end, we first analyze the browser launch process, and then employ several techniques that improve the performance of each step by using NVRAM. Specially, we focus on minimizing the launch time of browser by 1) prefetching the block sequence required for browser launch, 2) caching the web resources in the fast NVRAM, and 3) reusing the displayed bitmap data in the frame buffer. Through implementation, we show that our scheme significantly reduces the launch time of browsers.

Underground constructions continue to provide challenges to Geotechnical Engineers yet they pose the best opportunities for development and deployment of advance technologies for analysis, design and construction. The reason for this is that, by virtue of the nature of underground constructions, more data and information on ground characteristics and response become available as the construction progresses. However, due to several barriers, these data and information are rarely, if ever, utilized to modify and improve project design and construction during the construction stage. To enable the use of evolving realtime data and information, and adaptively modify and improve design and construction, the paper presents an analysis and design system, called AMADEUS, for underground projects. AMADEUS stands for Adaptive, real-time and geologic Mapping, Analysis and Design of Underground Space. AMADEUS relies on recent advances in IT (Information Technology), particularly in digital imaging, data management, visualization and computation to significantly improve analysis, design and construction of underground projects. Using IT and remote sensors, real-time data on geology and excavation response are gathered during the construction using non-intrusive techniques which do not require expensive and time-consuming monitoring. The real-time data are then used to update geological and geomechanical models of the excavation, and to determine the optimal, construction sequences and stages, and structural support. Virtual environment (VE) systems are employed to allow virtual walk-throughs inside an excavation, observe geologic conditions, perform virtual construction operations, and investigate stability of the excavation via computer simulation to steer the next stages of construction.

The purpose of this study is to investigate the contiguity of social capital and competence on business performance moderating by government policy. A total sample of 225 Village Credit Institution (LPDs) managers in Bali, the hypothesis is examined using the WarpPLS analysis. The findings reveal that social capital has an important role in enhancing performance, Competence is also an important factor for managers because it can intensify performance. Social capital is largely related to the recognition of society regarding the credibility of the managers, while competence emphasizes the ability of the managers to manage the organization. Government policy must be viewed as a regulation that is able to help improve performance. However, the public policies issued by the government are still unable to help improve social capital and competence. Thus, to create public policies that are able to improve the competence and social capital, a further examination into the variables must be conducted. The findings suggest that two-way communication must be developed and synergy between the government and organizations to create opportunities and overcome the increasingly complex business challenges. The results emphasized the importance of social capital in enhancing business performance. In addition, the role of competence is of equal importance to enhance business performance.
