This study includes services that require six professional guides - health care, exhibition performance, restaurant, shopping, business and daily life - as well as a trip-based tour, along with solving existing problems that may occur on domestic and overseas trips, and proposes services that connect users with proven professional guides. As a result of previous research, the most needed services among overseas travel were air tickets, accommodation, transportation, and guides, but as Korea enters an aging society, professional guide services are expected to increase daily demand. Based on this, the service technology, user scenarios and brand development were presented. This Service Proposal provides users with a personalized guide to knowledge or experience that they have not previously known, providing them with a wealth of experience. In addition, guides can help develop new fields of expertise and help improve professional guides' capabilities. Finally, the platform service is meaningful in that it enables the creation of jobs by enabling everyone to engage in economic activities, as it allows users to provide services through their own capabilities while at the same time being convenient for them.

The purpose of this study is to investigate the effect of transaction characteristics on transaction cost and choice intention by applying transaction cost theory to experiential product. Experience-specificity, transaction uncertainty, and personal uncertainty are proposed to reflect the characteristics of experiential products, and the effects of these variables on transaction costs and transaction costs are assumed to have an influence on the choice intention. The results of this study are summarized as follows. First, experience-specificity(site, physical equipment, knowledge skill, temporal), transactional uncertainty(product-, process-), personal uncertainty (preference-, and situation-) have a significant positive effect on transaction cost. Second, transaction costs (search, comparison, examination, negotiation, payment, delivery) have a significant negative effect on the choice intention of the experiential product. The results of this study show that the increase of transaction costs can reduce the choice of experiential products and the strategic consideration of experience specificity, transaction uncertainty and individual uncertainty are required to reduce transaction costs. In addition, experiential products lacked access from a transactional and cost-based point of view, and this study contributes theoretically by compensating for the lack.

As the demand for finding clearer information amid vast information acquisition increases, the enhancement of academic research services is highly important. In 2019, the Presidential Archives opened the only academic research services among the permanent archives management institutions. This study aims to identify the status of the insufficient use of academic research services implemented in the Presidential Archives, analyze problems and requirements through interviews with users who have used the Presidential Archives for academic purposes and conducted research, suggest a plan to upgrade the research services of the Presidential Archives, and offer a plan to improve the services of archives institutions accordingly. Researchers mostly sought information through an online search, but the information gap was large depending on the background knowledge, and the research scope was reduced because of insufficient information. Moreover, problems occurred regarding search tools, records management, and records disclosure, and most users were unaware of the academic research services. Therefore, the advancement plans entailed reducing the information gap among researchers, improving the search tool functions, creating more detailed descriptions of records, resolving geographic constraints, promoting academic research services and developing content, nurturing subject-specialized archivists, and providing online chatting services.

This study examines the perceptions and demands of pre-service early childhood teachers about the Demonstration of simulated instruction for 350 students in early childhood education at 3-4 years university located in Busan, Ulsan, and Gimhae. And through this, the purposes of study are to provide basic data based on the current level of pre-school teachers for instructors leading simulated instruction and to seek effective management plans for simulated instruction to improve teaching ability. As a result of the study, pre-service early childhood teachers recognized that simulated instructions were necessary in teacher training course and helped to improve teaching ability, but they did not actively agree to expand simulated instructions and were not very satisfied with the methods of instructors in demonstration of simulated instruction. They wanted to receive feedback from instructors who have practical teaching knowledge and skills based on field experience at least two times during preparation stage and evaluation stage of the simulated instructions. And they wanted to be guided specifically on principles and methods of preparing educational plans, effective interactions and questions with young children. They wanted the feedback, the most preferred form of feedback is form of participations by all class members and instructors. In addition to instructor's feedback, they required experience of simulated instruction in which infants and toddlers participate together.

This study investigates ethical dilemmas of teacher-librarians in their professional practice. Within the framework of "Librarians' Statement of Ethics" by Korean Library Association, the study used the survey and semi-structured interview with teacher-librarians. 259 teacher-librarians responded the survey and 5 teacher-librarians participated the interview. The survey was analyzed using descriptive statistics to find how often teacher-librarians experience ethical dilemmas. The semi-structured interview was transcribed and analyzed to draw the individual cases of teacher-librarians' ethical dilemmas. The results indicate that teacher-librarians experience ethical dilemmas in relation to information access and intellectual freedom most often. It was difficult for teacher-librarians to relate their professional duties with their expertise and that they were not clear on how to avoid copyright issues and how to deal with the balance between users and copyright holders. This study had implications that individual dilemma cases are so context-dependent that teacher-librarians had to make decisions individually. They tried hard to find the balance between protecting students from harmful resources and library ethics. Researchers and practitioners need focus more on finding where the balance is and how teacher-librarians deal with their ethical dilemmas.

This study is based on the importance of observation or exploration in contemporary scientific inquiry and the need to expand the learning materials of science inquiry. It aims to analyze students' characteristics of exploration in abduction by developing and applying an educational program using art materials. For this study, a program named "Scientist going to the museum" utilizing artistic materials such as Oriental and Western paintings, mythology, orchestral suite, and traditional houses, was developed and five middle school students participated. Students who found and explored interesting phenomena in the work were divided into three main groups depending on the characteristics of the exploration activity. Some students observed and described elements that could be connected to scientific concepts, while others mainly explored everyday elements that were relatively unrelated to such concepts. Moreover, another type of students explored the works based on their subjective evaluations. This study shows that learning materials that cannot be visually explored are not suitable for abductive activities that students' prior knowledge has a significant impact on their exploration, and that educational materials for earth science inquiry could be expanded. This study also provides an example of learning materials and methods, and that abduction may be utilized for learning astronomy.

The 2020 summer extreme flood severely disturbed the riparian ecosystem of the Seomjin River. Some trees were killed by the flood impact, whereas others have recovered through epicormic regeneration after the disturbance. At the same time, several tree individuals newly germinated. This research aimed to explain the recovery of the riparian ecosystem by spatial proximity between each tree individual of different characteristics, such as "dead", "recovered", and "newly germinated". A spatial point pattern analysis based on K and g-functions revealed that the newly germinated trees and the existing trees were distributed in the spatially clumping patterns. However, further detailed analysis revealed that the new trees were statistically less attracted to the recovered trees than the dead trees, implying competitive interactions hidden in the facilitative interactions. Habitat amelioration by the existing trees positively affected the growth of the new trees, while "living" existing trees were competing with the new trees for resources. This research is expected to provide new knowledge in this era of rapid climate change, which likely induces stronger and more frequent natural disturbance than before. Environmental factors have been widely used for ecosystem modeling, but species interactions, represented by the relative spatial distribution of plant individuals, are also valuable factors explaining ecosystem dynamics.

This study conducted a systematic literature review on nursing students to find out the types and composition of patient safety-related education programs. The research was conducted systematically using PRISMA. The patient was a nursing college student, and the intervention was patient safety education. The outcome was either numerical or descriptive reports of the results measured using the tool. The types of research were carried out including randomized design, quasi-experimental design, one-group design, survey and qualitative research. The paper was searched through Medline, Embases, CINAHL, DBpia, Riss and KISS. A total of 2,468 papers were searched in the search results, and nine papers were used for analysis as a result of extracting data according to PICO. The characteristics of patient safety education of nursing college students were classified according to the teaching method, period, result variables and measurement tools. As a result, patient safety education consisted of a variety of subjects, and was being taught through lectures, clinical practice, laboratories, and simulations. The period of education also varied. The resulting variables were mainly checked for knowledge, attitude, and skill, and the tools used to measure them varied. Patient safety education for nursing college students was conducted through various topics, methods and periods at home and abroad. Therefore, continuous research is needed to establish consistent and integrated patient safety education in educational institutions and working institutions to produce nursing personnel with patient safety capabilities.

The aim of this study is to examine the effectiveness of non-face-to-face classes conducted due to the COVID-19 crisis. In order to achieve this goal, a non-face-to-face class with flipped learning was applied in one subject of clothing major held at 'S' University in Cheongju, Korea. In addition, this study tried to analyze the differences between pre- and post-non-face-to-face classes in problem analysis ability, resource/information/technology literacy, convergent thinking ability as core competencies, and overall learning satisfaction. As a result, after participating in the non-face-to-face class in which the flipped learning was applied, the students recognized that their abilities improved in the three problem-solving competency sub-areas, and their overall learning satisfaction also increased. The effectiveness of non-face-to-face classes in the field of clothing and fashion has been mainly measured in fashion design and clothing construction courses. However, based on the results of this study, it can be suggested that non-face-to-face classes in a theory-oriented lecture-type class can be effective methods for improving students' core competencies such as problem-solving skills if teaching-learning methods such as flipped learning are applied. Therefore, the results of this study will be useful data for designing differentiated non-face-to-face class strategies in a theory-oriented lecture-type class to improve the core competencies of college students.
