Within the framework of DECOVALEX-2019 Task D, full-scale engineered barriers experiment (FEBEX) at Grimsel Test Site was numerically simulated to investigate an applicability of implemented Barcelona basic model (BBM) into TOUGH2-MP/FLAC3D simulator, which was developed for the prediction of the coupled thermo-hydro-mechanical behavior of bentonite buffer. And the calculated heater power, temperature, relative humidity, total stress, saturation, water content and dry density were compared with in situ data monitored in the various sections. In general, the calculated heater power and temperature provided a fairly good agreement with experimental observations, however, the difference between power of heater #1 and that of heater #2 could not captured in the numerical analysis. It is necessary to consider lamprophyre with low thermal conductivity around heater #1 and non-simplified installation progresses of bentonite blocks in the tunnel for better modeling results. The evolutions and distributions of relative humidity were well reproduced, but hydraulic model needs to be modified because the re-saturation process was relatively fast near the heaters. In case of stress evolutions due to the thermal and hydraulic expansions, the computed stress was in good agreement with the data. But, the stress is slightly higher than the measured in situ data at the early stage of the operation, because gap between rock mass and bentonite blocks have not been considered in the numerical simulations. The calculated distribution of saturation, water content, and dry density along the radial distance showed good agreement with the observations after the first and final dismantling. The calculated dry density near the center of the FEBEX tunnel and heaters were overestimated compared with the observations. As a result, the saturation and water content were underestimated with the measurements. Therefore, numerical model of permeability is needed to modify for the production of better numerical results. It will be possible to produce the better analysis results and more realistically predict the coupled THM behavior in the bentonite blocks by performing the additional studies and modifying the numerical model based on the results of this study.

RI-Biomics is a promising radiation convergence technology that combines radiation with bio science as new growth power technology. Many developed countries are focusing active support and constant exertion to dominate the RI-Biomics market in advance. In order to achieve global leadership in the RI-Biomics field, we need more highly advanced technologies and professional manpower. In fact, we have less manpower compared to technology we currently hold. In this study, we established a basic infrastructure to train professional manpower in the RI-Biomics field by developing/operating optimum training program through expert interviews and survey. The developed program has four organized sections to understand overall procedure of RI-Biomics. To evaluate our training program, we performed test operations with eight students who have a major related to RI-Biomics for three weeks in KARA (Seoul) and KAERI (Jung-eup). In detail, radioisotope usage and safety management were conducted for one week as basic course, RI-Biomics application technology was conducted for two weeks as professional course. To verify performance results of training program, we conducted to journal research, daily reports, and survey on participants. The results show a high level of satisfaction with training programs and continuous intention of involvement in our program. We also need to develop an intensive course to train high-quality human resources and to operate training program continuously. This training program will be used as basic materials for the development of RI-Biomics curriculum for university. Hence, we will expect that our training program contributes in training a professional manpower and develop RI-Biomics technology.

This study investigated the relationships among middle school students' perceptions on the roles of online tutor, their deep learning, achievement, and overall evaluation of learning experiences in the context of inquiry based online gifted mathematics and science learning. For this purpose, 249 middle school students who took online course were surveyed about their perceptions on the degree to which their tutor performed the roles as an online tutor. The students were also asked about the activities which indicate deep learning approaches and overall course experiences such as the level of satisfaction, understanding and engagement in the course. The regression analyses were conducted to examine the relationships of students' perceptions on the roles of online tutor, deep learning, achievement, and overall course experiences. The results first showed that the roles of online tutor which affects students' deep learning approach such as high-order learning, integrative learning, reflective learning were the role as a subject matter and evaluation expert. Among the sub variables of deep learning approach the variable that was related to students' overall achievement was the use of high-order learning strategy. Second, the achievement in inquiry task was related to the role of tutor as a guide of learning process and method. Third, students' overall course evaluations such as the level of satisfaction, understanding and engagement were not related to any role of tutor.

As of 2019, for the 'Island I Want to Visit' project, Banwol and Bakji Islands, located in Shinan-gun, started color marketing to create a tourist attraction by painting roofs, buildings, and facilities purple. As this landscape change was evaluated as a 'dangerous but beautiful attempt,' it was recognized as the 'World's Best Tourism Village' in 2021, drawing attention from domestic and foreign tourists. However, the residents of the islands, who created and enjoy the benefits of the landscape, were alienated from the planning stage. This study investigated the meanings and symbols of residents' perceptions of the purple landscape. The cultural landscape frame of new cultural geography, which interprets the landscape's symbolic meaning and ideological signs, was utilized. In addition, a holistic approach was applied to understand the residents' perceptions of the multi-layered environment. Therefore, the perception of purple, the main color of the islands, the overall landscape and individual places, and the general perception of the Purple Island project were investigated. After the Purple Islands Project, the main senses for recognizing the villages focused on sight, and the residents were satisfied with the purple landscape as it improved the underdeveloped village environment. This satisfaction was based on lessening the negative memories experienced as an island rather than a value judgment on the purple color. In addition, the perception of the symbolic landscape, which has a social and universal system, has been subdivided and reorganized, including for tourism functions. It can be understood as an aspect of the spectacle landscape that appears in cosmopolitanism. However, in the process of transforming into a tourist attraction, it was discovered that the residents recognize the value of local resources and create a new cultural landscape. In addition, the perception of the relationship between Banwol and Bakji has also changed around tourism.

This study examines the concept and characteristics of immersive theatres through previous studies. Immersive Theatres can be understood as a form of performance that breaks the boundaries between the stage and the auditorium in various spaces so that the audience can actively participate in the performance or immerse themselves sensibly. However, since it absorbs various art forms and continues to change and develop, it is important to recognize the concept by grasping its characteristics as an immersive experience rather than defining it as one. Based on the theoretical background of the concept and characteristics of the theatrical producers and immersive theatres, the producing immersive theatre < The Great Gatsby> is analyzed to derive differences between the immersive theatre and the general performances. In conclusion, it is important to recognize that immersive theatres have audiences at the center of all aesthetic performance environments. The role and position of the audience as a "passive consumer" change to an "active and creative consumer" in immersive theatres where the audience-centered immersive environment and experience are the key, and it was found that not only producers but also the creatives should change their perception of the audience and reflect it in the producing.

Policy problems are complex due to diverse participants and their relations in the policy processes. Defining the right problem in the first place is important because Type III error is likely to happen without removing rival hypothesis in defining the problem. This study applies Boundary Analysis suggested by Dunn to structure IT policy problems in Korea. The time frame of the study focuses on 5 years of Lee Administration and data are collected from four newspapers. Using content analysis, the study, first, elaborates total 2,614 policy problems from 1,908 stakeholders. After removing duplicating problems, 369 problems from 323 stakeholders are identified as a boundary of IT policy problem. Among others, failures in government policies are weighted as the most serious problems in IT policy field. However, many significant problems raised by stakeholders dated back to more than a decade, and those are intrinsic problems, which initially caused by market distortions in the IT industry. Therefore, we should be cautious not to overemphasize the most conspicuous problem as the only problem in the policy field when we interpret results of problem structuring.

The purpose of this study was to examine the perception of the childcare teachers regarding accreditation procedures and feasibility of the second accreditation index according their past participation in the accreditation process. The objects were 193 childcare teachers working at child care centers that were accredited using the initial accreditation index. The collected data was analyzed using frequency, percentile, $X^2$, and t-test. The major findings are as follows: First, childcare teachers without accreditation experience perceived 'continuing education of child care center directors and teachers' to be the most important for quality maintenance after successful accreditation. In contrast, childcare teachers with accreditation experience placed the most importance on 'childcare teachers' motivation and continuing enrollment'. Second, childcare teachers with accreditation experience perceived higher feasibility in the subcategories of 'art activity materials' in the category of child care environment, 'providing operation policies and information of child care teachers', 'care for children', and 'employment contract' in the operation & management category, 'sanitary management of food, cooking and feeding', 'care of sick or injured child', 'health management of children and childcare teachers', 'snacks for children' in the category of health and nutrition and 'safe procedures for handing over children' in the category of safety. In general, childcare teachers with accreditation experience perceived higher feasibility of the second accreditation index in all categories.

The purpose of this study is to present the basic data needed to improve the arts, music, and physical education provided by local child care centers based on an investigation of the current status of and satisfaction with the education. The subjects of this study were 17 local child care centers in Gyeonggi-do, South Korea, and the situation of the arts, music, and physical education programs operated from 2014 to 2016 were examined. In addition, 419 children who received the education were surveyed to evaluate their level of satisfaction. The results of this study are as follows. As regards the status of the arts education from 2014 to 2016, it was observed that three of the 17 local child care centers did not have any arts, music or physical education at all, while six of them continuously implemented all three of these programs during this period of time. Two and six of the 17 institutes had arts, music, and physical education programs for two years and one year, respectively. All of the teachers who ran the arts and music education programs of the 17 institutes were arts and music majors who were certified teachers of the liberal arts. However, the physical education programs were run as volunteer activities by college students majoring in physical education. The survey on the level of satisfaction of the children who participated in the arts, music, and physical education programs showed that they were helpful for the overall life experience of the children and that they were more helpful for the boys than for the girls. The level of satisfaction with the education was high for most of the students who participated in the programs, however the boys were more satisfied than the girls. When asked whether they would participate in the arts, music, and physical education programs again, most of the respondents answered that they would do so. The boys were more likely to participate again than the girls. Based on this study, in order to enhance the creativity and personality education of the children using the local child care centers, higher quality education is needed. Arts and music education can be used to help children to learn to communicate smoothly with their friends. In addition, it seems to be necessary to enhance the education by setting goals that are suitable for its purpose, in order to provide creative arts and music education that contributes to the physical health and emotional stability of the children.

The purpose of this study was to develope issue-centered teaching learning process plan for environment-friendly housing education and to apply it to the housing section of Technology Home Economics in a middle school. PRO-CON cooperative group model was used for the teaching learning process plans of 2-session lessons according to the ADDIE model. In the development stage, 7 activity materials and 20 teaching learning materials (4 reading texts, 12 pictures and photos, & 5 moving pictures) were developed for 2-session lessons. The plans applied to the 7 classes, 222 students, in the third grade of the G middle school in Gyeonggi-do during July 10th-17th, 2008. The results showed that the final pro-con was influenced by the rationals of juries' pro-con of each team and the representative's discussion besides one's environmental perspective. The intention to implement environment-friendly housing activities was significantly increased between before and after the lessons. The contents, methods, goals, and process of the 2-session lessons were evaluated over medium to somewhat higher levels. Those evaluations except methods and general satisfaction with the lessons were differed by sex, students' and their families' interests in environments but not by the type of housing. These results might support that pro-con cooperative group model of controversial issues on parking lot would be appropriate to environment-friendly housing lessons and could apply to broad issues on housing and various schools in other areas.

This study was conducted to discover the meaning and the essential structure of the experiences of nursing students' introductory clinical practice. The participants were eight nursing students who had carried out the introductory clinical practice at a hospital. The data was collected from July 15 2019 to July 31, 2019 through focus group discussions and in-depth individual interviews using non-structured questionnaires. The data was analyzed by Colaizzi's phenomenological analysis methodology. The introductory clinical practice experienced by nursing students was categorized as followed: 'Feel worried and concern about expectations at the same time', 'Hospital experience as reality', 'Becoming accustomed to complexed emotion's, 'The first step of becoming a nurse', and 'Preparation for the future'. The five categories were expanded in the same context according to time. The essential structure of the clinical introductory practice experiences of the nursing students revealed by the study is that they begin to practice feeling worried and concerned about expectations, and concern about experience and adaption to various situations, emotions and preparation for the future. Based on the results obtained from this study, it is necessary to develop a realistic and effective education program before starting clinical practice.
