This research is a case study about "Critical Thinking and Debate Education" class which was done for freshmen at the engineering college of "S" Women's University. Real time remote classes through LMS and ZOOM were the most effective tools under on-line circumstances, considering the fact that video lectures only cannot cultivate students' capabilities of critical thinking and communication. Throughout the analysis on students' self-reflection journals and lecture evaluations, this paper examined considerable future points and the pros and cons of "Critical Thinking and Debate Education" under online presentation and discussion situation. As research outputs, students told they could feel less nervousness and anxiety when they exercise and have a presentation because they could choose familiar space for them. In addition, students also told that they feel comfortable about both self-feedback and peer evaluation, repeatedly seeing the recorded video clip. However, on the contrary, sometimes students felt uncomfortable due to unstable internet connection through the online classes, and they also were regretful about the missing chances of interaction between a teacher and students and of intimate exchanges among students. They also told they had felt a kind of limit of enhancing their presentation skills just in front of the monitor. Considering these outcomes, this research paper points out that online education needs to be proceeded by strengthening multi layered feedback to students with the build-up of a non-face-to-face stable educational infrastructure, application of online instructional strategy, and utilization of YouTube platform and video contents. Through this research paper, I hope the new system of encompassing on/off line "Critical Thinking and Debate Education" and effective teaching and learning method can be developed soon by strengthening the strength of online education.

Many countries design and implement informatics curriculum based on core competencies to respond to the demands of development and reform in rapidly changing times. In this paper, we developed the core competencies framework of elementary information education by comparing and analyzing the core competencies and suggested the direction of the composition of elementary informatics subjects. We found that social-emotional skills, communication, creativity, responsibility, culture and ethics, problem-solving, collaboration and abstract competencies overlapped among the capabilities presented by each country and institution, and computational thinking and information technology utilization skills in Korea. Therefore, we proposed to reflect the core competencies of the framework in the elementary informatics curriculum. Moreover, we also suggested enhancing problem-solving skills, strengthening social responsibility and cultivating convergent skills to organize the curriculum. We hope that this thesis will expand the necessity of organizing an elementary information curriculum that reflects core competencies in the 2022 revised curriculum.

In this paper, we present a mobile application for 'personalized customized learning' for children with articulation disorders using an artificial intelligence (AI) algorithm. A dataset (Data Set) to analyze, judge, and predict the learner's articulation situation and degree. In particular, we designed a prototype model by looking at how AI can be improved and advanced compared to existing applications from the UX/UI (GUI) aspect. So far, the focus has been on visual experience, but now it is an important time to process data and provide a UX/UI (GUI) experience to users. The UX/UI (GUI) of the proposed mobile application was to be provided according to the learner's articulation level and situation by using CRNN (Convolution Recurrent Neural Network) of DeepLearning and Auto Encoder GPT-3 (Generative Pretrained Transformer). The use of artificial intelligence algorithms will provide a learning environment with a high degree of perfection to children with articulation disorders, thereby enhancing the learning effect. I hope that you do not have any fear or discomfort in conversation by improving the perfection of articulation with 'personalized and customized learning'.

This study aims to examine the cases of overseas experience programs centered around middle school students in South Korea and to derive implications for future overseas experience programs. To achieve this, data were systematically collected through search engines based on keywords, followed by comparative analysis. Frequency analysis, independent sample t-tests, and cross-analysis were conducted using SPSS 23. The research findings are as follows: First, the programs are operated nationwide, with a focus on smaller schools in various regions, and are particularly active in the Jeolla provinces. Diverse public funding, such as from the board of education and local governments, has been invested, categorizing operational costs into full financial coverage among others. The programs primarily took place in Southeast Asian countries close to South Korea. Second, the purposes of these middle school overseas experience programs largely encompass career exploration, cultural experiences, tourism, and sister school visits. We hope that school-based overseas career exploration programs are actively operated to provide opportunities for enhancing global competence and global citizenship, as well as exploring career paths.

The society we are living in has being changed to the age of the intelligent information society after passing through the knowledge-based information society in the early 21st century. In this study, we have developed the instructional model for software education based on the machine learning which is a field of artificial intelligence(AI) to enhance the core competencies of learners required in the intelligent information society. This model is focusing on enhancing the core competencies through the process of problem-solving as well as reducing the burden of learning about AI itself. The specific stages of the developed model are consisted of seven levels which are 'Problem Recognition and Analysis', 'Data Collection', 'Data Processing and Feature Extraction', 'ML Model Training and Evaluation', 'ML Programming', 'Application and Problem Solving', and 'Share and Feedback'. As a result of applying the developed model in this study, we were able to observe the positive response about learning from the students and parents. We hope that this research could suggest the future direction of not only the instructional design but also operation of software education program based on machine learning.

Recent reports about economic structure and changes show that global economy changes to rely on service rather than manufacturing. This phenomenon can be explained in two ways: the growth of service industry itself and the increasing reliance on service by other industry areas. The importance of service is indicated by the fact that the contribution of research and development, marketing, and finance to the revenue generation of companies is getting greater than that of manufacturing. This change in the economic structure calls for researchers' attention on the importance of service and the service-based economy. In the service-based economy, firms are considered value proposition providers and consumers actual value creators so that the concept of co-value creation becomes a key thesis to study. However, there are a variety of definitions of service and diversified measurements of service anchored in the supplier-oriented understanding of service yet. This lack of understanding of the service and the economic paradigm change causes a lot of problems in the areas of service productivity, service quality, and service innovation. Even though a new movement called service science started and rigorously pursues the way of enhancing the understanding of the economic change and service productivity, there is no framework that provides a unified view about the new role of service, service productivity, service quality, and thus service innovation. This study proposes a unified framework to provide a structured view about service provision and to facilitate the research on service. The framework is built on the concepts from previous studies about service marketing and service science: service life cycle and service networks including value activity network, resource integrator network, and capability network. We hope this study can be used as the basis for future studies on service science.

Rapid growth in computer and digital-based technology has brought about changes in various human services including psychotherapy. This paper will look into one of these changes, focusing on a rising area of mental health therapy : Art therapy. Although development of art therapy is not so fast compared to other branches of psychotherapy, some art therapists are studying how to adopt and use it properly. Both art therapists and mental health experts have concluded that technology is a powerful tool despite its limitations and reservations. While some of them think that patients have benefited from the implementation of technology, others have felt concerns about the replacement of basic professional practices. The use of digital technology in the area of art therapy, however, continues to increase, encouraging patients to benefit from it in various therapeutic processes. This thesis therefore focuses on the analysis of literature related to digital art therapy published up to now. The following field study on Korean art therapists aims to examine the current practice of digital art therapy and discuss its feasibility and future. These two methods will contribute to enhancing the understanding of art therapy not only in theory but in practice and also suggest how digital art therapy may overcome limitations of conventional art therapy by exploiting its advantages. Furthermore, this study will present some clues on a possible new position of digital art therapy in the future. I hope that this analytical examination on digital art therapy will stimulate further discussion on this issue and particularly encourage more interdisciplinary work between art therapy and digital technology.

The ultimate goal of rehabilitation is social integration. Reemployment is, for the disabled workers, the primary source of not only income, but also identity and interaction. Unfortunately, for most disabled workers employment represents only a yet-to-be-fulfilled hope, a close but inaccessible goal, a daily reminder that they are not among the majority. The purpose of this study is to estimate reemployment rate in the industrial injured and to find factors affecting reemployment of disabled workers owing to industrial injury, and to make policy implication for the better industrial injury compensation rehabilitation system. The data were obtained through telephone interview with disabled worker who completed work injury compensation process in 1996-1997. The final sample was consisted of 1,060 respondents. The major findings were that almost lout of 3 disabled worker returned to work, and that the factor affecting reemployment of the disabled workers were severity injury, ADL(activity of Daily Living), the perception of disability severity, controlling for the demographic factors such as sex, age, education, marital status. The results indicated that psychosocial factors as well as physical function had influces on returning to work. The current findings suggests that rehabilitation services and policy aimed at enhancing vocational rehabilitation program and rehabilitation engineering services, and improving psychosocial resources should be considered by rehabilitation professionals and policy makers.
