The purpose of this study is to identify the differences of student satisfaction depending on tutor's content expertise and experience in PBL of nursing. Nursing department, the subject of this study, is operating Hybrid PBL Curriculum that integrates the courses in nursing for all grades. Tutor's expertise was categorized based on their final dissertations and the clinical fields for which they worked. Tutor's experience in PBL is less than one year for beginners and more than 10 years for experts. After the PBL class for 6 weeks, the 3rd grade students were surveyed. The results showed that there was a statistically significant difference in the student satisfaction according to the content expertise, however, the student satisfaction depending on tutor's experience and the interaction effect between tutor's content expertise and experience were not significant. This study has raised the importance of the role of tutor as content expert in PBL. It is suggested that future studies be repeated for more tutors with diverse subject areas and majors to examine the differences between diverse variables other than student satisfaction.

The goal of this study was to examine the PCK required for science teachers and PCK required for university teacher educators in terms of school science knowledge, science teaching and learning, and the role of science educators, which are the main axes of science education in future schools, and to explore the relationship between them. This study is a follow-up to a previous stage of research that explored the prospects for changes in schools in the future (2040-2050) in terms of school knowledge, educational methods, and teacher roles. Based on in-depth interviews, qualitative and semantic network analyses were conducted to derive and compare the characteristics of PCK and PCK. As for the main research results, science teacher PCK in future schools should include expertise in organizing science classes centered on convergence topics, expertise in digital platforms and ICT use, and expertise in building a network of learning communities and resources, as part of the expertise of human teachers differentiated from AI. Teacher educators' PCK includes expertise in the research and development of T-L methods using AI, expertise in the knowledge construction process and practice, and expertise in developing preservice teachers' research competencies. Discussed in the conclusion is the change in teacher PCK and teacher educator PCK with changes in science knowledge, such as convergence-type knowledge and cognition-value integrated knowledge; and the need to emphasize values, attitudes, and ethical judgments for the coexistence of humans and non-humans as school science knowledge in the post-humanism future society.

This study analyzed the change of teaching expertise of pre-service teachers through TPACK education. In this study, we applied a programming-based TPACK education program developed by Kim and Lee (2019) to 20 prospective teachers. To analyze the pre-service teachers' teaching expertise analyzed the lesson plan prepared before, during and after applying the educational program. As a result, Few teachers use technology in lesson plan, and the design of the instructor-led or experiment to confirmed content in curriculum or textbook. The use of technology has increased in the second Teaching Plan, but the technology was not used depending on the educational context. In the third lesson plan, all pre-service teachers were able to use technology in an educational context. Moreover, the teaching expertise of the pre-service teacher showed a statistically significant improvement in the lesson plan. This study founded that the programming-based TPACK education program was effective in enhancing the teaching expertise of the pre-service teacher.

This study was designed to investigate the perception of the competencies of using Importance-Performance Analysis (IPA). The subjects of the study were 318 clients and 118 consultants. Descriptive statistics, paired t-tests, and Importance-Performance Analysis (IPA) were conducted based on perception levels of clients and consultants to increase understanding of current situations and trends. Findings are expected to assist in planning. Regarding the perception of clients, Quadrant 2 (Concentrate Here) included consulting supervision expertise and content expertise, and Quadrant 4 (Possible Overkill) included skill expertise. Regarding the perception of consultants, Quadrant 1 (Keep Up the Good Work) included skill expertise; Quadrant 2 (Concentrate Here) included content expertise; and Quadrant 3 (Low Priority) included consulting supervision expertise. Results revealed that clients had no responses for Quadrant 1, but they offered 10 items associated with Quadrant 2, one item for Quadrant 3, and four items for Quadrant 4. Consultants responded with five items for Quadrant 1, three items for Quadrant 2, three items for Quadrant 3, and four items for Quadrant 4.

Online reviews attract much attention because they play an essential role in consumer decision-making. Therefore, it is necessary to investigate the review attributes that affect the perceived helpfulness of consumers. However, most previous studies on the helpfulness of online reviews mainly focus on quantitative factors such as review volume and reviewer attributes. Recently, some studies have investigated the impact of review content and linguistic style matching on consumers' purchase decision-making. Those studies show that consumers consider additional review attributes when evaluating reviews in decision-making. To fill the research gap with existing literature, we investigated the impact of review content and linguistic style matching on review helpfulness. Moreover, this study investigated how the reviewers' expertise moderates the effect of the review content and linguistic style matching on the review helpfulness. The empirical results show that positive affective content has a negative effect on the review helpfulness. The negative affective content and linguistic style matching positively affect review helpfulness. Review expertise relieved the impact of negative affective content and linguistic style matching on review helpfulness. According to the mechanism confirmed in this study, online e-commerce companies can achieve corporate sales growth by identifying factors affecting review helpfulness and reflecting them in their marketing strategies.

This research has investigated the perceptions of subject specialization services and the opinions of students majoring in library and information science preparing for librarianship, librarians operating in the field, and library directors on the status and ways of nurturing subject specialization for librarians, among others. To this end, based on the results of previous research and the survey questionnaire analysis, we have presented a policy to train subject librarians. First, we have proposed a plan for systematizing the current educational system within the department of library and information science. We have also suggested ways to secure subject expertise based on curriculum management, minor programs, multi-major programs, and interdisciplinary major programs based on the standard curriculum model. Second, we have presented a subject specialization educational system for field librarians, and further suggested details for the development of an educational program that can help build subject expertise and the operation of educational methods as well as the personnel in charge of implementing the educational programs. Third, we have proposed institutionalization of the qualifications of the subject librarian where the qualification requirements have been organized considering academic background, major program, library career, and career experience in the subject specialization service, further suggesting the implementation and maintenance of the system.
