Information and Communication Technology (ICT) remote soil moisture control system including soil sensing, automatic water supply chain, and remote alarming system was established on reclaimed land and operated stably. The system was operated using river water around the reclaimed land without fertilizer. On applying this system to control soil moisture, the kenaf germination rate was improved up to two times. Kenaf biomass was 4,748 kg/10a and was higher than that of untreated soil moisture management. When the nutritious liquid fertilizer was used, kenaf yield reached 8,390 kg/10a, which was lower than 10,848 kg/10a of the non-reclaimed land treated with standard chemical fertilizers. As the soil moisture was managed stably through the ICT remote soil moisture control system, the quality of the kenaf crop was improved, resulting in a 7% increase in dry weight, and a 11.5% increase in plant hardness. The estimated kenaf yield was 5,039 kg/10a when 800 tonnes of water were supplied by the ICT remote soil moisture control system with the stream water around Saemangeum reclaimed land without chemical fertilizers and organic matter.

In this study, We developed VR (Virtual Reality) geological resources based on the Geo Big Data of the Big Data platform that provided by the Korea Institute of Geoscience and Mineral Material (KIGAM). So students selected the theme of lessons by using these resources and we operated Remote classes using the materials that developed as to Virtual Reality. Therefore, the geological theme maps provided by the Geo Big Data Open Platform were reconstructed and produced materials were created for Study about Real Korean geological outcrops grounded in Virtual Reality. And Topographic information data was used to produce class materials for Remote classes. Twenty students were selected by Random sampling, and data were collected by conducting a survey including interviews to confirm the change in students' perception of remote classes in virtual reality geological data development and the effect of the classes, so data were analyzed through inductive categorization. The results of this study are as follows. First, students showed positive responses in terms of interest, utilization, and knowledge utilization as taking remote classes for developing geological data in virtual reality geological data. This is the result of showing the adaptability of diverse and flexible learning getting away from a fixed framework by motivating and encouraging students and inducing cooperation for communication. Second, students recognized distance education in the development of Virtual Reality geological data as 'Realistic hands-on learning process', 'Immersive learning process by motivation', and 'Learning process of acquiring knowledge in the field of earth science'.

This study aims to apply the problem-based learning method to a college course on 'Consumer Studies' in a teacher education program. The participants of this study were 27 undergraduate students who were enrolled in the course. The PBL class was implemented for seven weeks using two problems: proposing special lectures on economic concepts and financial consulting. The effectiveness of PBL was analyzed through self-reflective journals, self-assessment, and a learning satisfaction survey of students. The result of this study was as follows. Students achieved the learning objectives and strengthened their collaboration and communication skills with team members during the PBL process. Moreover, students improved their self-directed learning and problem-solving ability through the PBL class. The results of self-assessment, in terms of learning task performance, active interaction, and self-directed learning were generally high at 4.63 points. In addition, the overall learning satisfaction level was very high, with a score of 4.75. The results will provide effective information on PBL classes to instructors and prospective teachers and will be used as data for learner-centered PBL classes.

This study aimed to examine relationships between founders' entrepreneurial leadership, team learning behavior, team boundary spanning, and perceived performance in early-stage startups. The following results were recorded: (i) the indirect effects of entrepreneurial leadership on perceived performance via team learning behavior were statistically significant (β=.309, p<.05). (ii) relationships between team learning behavior and perceived performance were strengthened by team boundary spanning behavior (β=.259, p<.05). In this study, three practical implications are provided as follows: (i) startups need to seek team learning readiness and external learning stimulus to facilitate generative and transformative team learning; (ii) accelerators need to develop an entrepreneurial leadership program for founders; and (iii) startups need to explore external information by interacting with investors, R&D institutions, and other startups to strengthen the impact of team learning behavior on performance. Furthermore, two directions for future research are suggested as follows: (i) future researchers need to test causal relationships between entrepreneurial leadership and team learning behavior based on a newly designed time-series measurement plan; (ii) the actual effects of entrepreneurial leadership, team learning behavior and team boundary spanning on financial performance need to be tested two or three years later when the financial performance of early-stage startups usually becomes evident.

The purpose of this study is to find out what kind of experience docent programs provide to visitors in museums by means of Giorgi's phenomenological method. In-depth interview was conducted with 6 visitors who had experienced firsthand. As a result of the coding based upon Giorgi's method, it was divided into 6 categories and 21 subcategories, and the following results were obtained. First, the reason that the subjects of the study participated in the docent program was due to factors such as information, coincidence, induction of companions, and habits. Second, from participating in the docent guide, they felt that the docent led them to actively visit the exhibition, get the educational effect, and generate interest and curiosity. Third, looking at the reaction after participating in the docent guide, in addition to the positive influence, the docent's reading-like explanation and the problem of the microphone facility were negative experiences. Through this study, it was confirmed that there were many visitors who recognized that the docent guide was helpful in viewing the exhibition and experienced positive reactions. In addition, in the evaluation of the commentary of docent, there was a difference of views between art-related majors and non-majors. In addition, as a result of analyzing the participants' experiences according to Holt's frame of experiential consumption, it was found that the docent experience was a comprehensive consumption behavior appearing in all four fields.

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.

This study aimed at analyzing the educational needs of home economics teachers for food literacy cultivation education in secondary school home economics. A total of 192 home economics teachers were surveyed about their perceptions of importance and performance of food literacy education content categories and elements, and their priorities were identified. Among the 38 content elements presented, home economics teachers recognized that the current performance level was significantly lower than that of the importance over 34 content elements. Based on the Borich educational needs assessment and the Locus for Focus Model, we identified five content elements with 'very high' educational needs ('food security/food sovereignty', 'reducing food-related waste', 'food waste management and recycling', 'food-related waste recycling', and 'country of origin information'), and four content elements with 'high' educational needs ('genetically modified food', 'ethical food consumption', 'food additives', and 'eco-friendly agricultural products'). These results indicate that dietary education in secondary school home economics should emphasize both the production and disposal of food. The findings of this study suggest implications for the needs for a new dietary education in secondary school home economics that allows students to learn all stages of food system. These results can also be used as a basis for dietary education for cultivating food literacy in secondary school home economics education.

The goal of the study is to provide a new type of audio-visualization method through case analysis and work production based on Polysomnography(PSG) data that is difficult to interpret or not familiar to the public. Most art works are produced with conscious actions during waking hours. On the other hand, during sleep, we get into the world of unconsciousness. Therefore, through the experiment, want to discover if could get something new when we were in the subconscious state, and if so, wondered what kind of art could be made through it. The study method is to consider definition of sleep and sleep data first. The sleep data were classified into normal group and Narcolepsy, Insomnia, and sleep apnea by focusing on sleep disorder graphs that is measured by sleep polygraph. After that, I refined and converted the acquired biometric data into a text-based script. The degree of sleep in the text form of the script was rendered as a 3D animated image using Maya. In addition, the heart rate data script was transformed into a midi format, and the audition was implemented in the garage band. After Effects combines the image and sound to create four single channel images of 3 minutes and 20 seconds each. As a result of the research, I made an opportunity for anyone easy to understand the results, having difference with the normal data, through art instead of using difficult medical term. It also showed the possibility of artistic expression even when conscious actions did not occur. Through the results of this research, I expect the expansion and diversity of artistic audiovisual expression of biometric data.

The purpose of this study is to find out how those taking early childhood preservice teachers experience their learning through learner-centered education and the meaning given by such experiences to grasp their values. Especially, to look into experiences of learning the project approach theory studied and directly experienced, which is one of the early childhood educational approach methods, data on participatory observation, personal interviews, personal reflective journals, activity reports and ect. were collected and analyzed by the current writer, who fully participated in the class. The meaning of early childhood preservice teacher'experiences in the project approach was analyzed from the two aspects of 'my' learning activities and 'teacher's teaching activities. In the aspect of 'my' learning activities, they got indulged through purposeful practices in the process of tackling problems that originated from personal interest and wanted to share the joy of learning they'd had with others. Aware of themselves as doers of behavior and thinking, they were found to be able to focus an 'my' own learning activities based on these learning experiences of theirs. In the aspect of 'teacher's teaching activities, project theories and practices done at the same time helped them internalize the project and they learned possible changes ign the project by experiencing actual cases. To sum up, the project approach has its meaning in that it not only helps teachers learn theoretical knowledge but also have reflective thinking through their experiences as doers of learning and form practical knowledge. Accordingly, it indicates th need for intensive discussion on the project approach as a way to educate pre-teachers or current ones.

베트남 소수민족 공동체 중 Hmong족은 중요한 구성원이라고 여겨져 왔다. 타지에서 베트남으로 이민 와서 다른 민족들과 함께 오랫동안 살아 왔지만 Hmong족은 자기의 민족문화 특색을 잘 지켜왔다. 그런데 지난 몇 년 동안 전통적인 종교와 달리 새로운 종교를 믿게 되는 방향으로 Hmong족의 심령의 종교는 많이 변하고 있다. 그 중에 특히 주목받은 것은 개신교의 유입이다. 개신교는 직접적, 간접적 선교 방법으로 Lao Cai에 있는 Hmong족 공동체에 자연스럽게 유입되었다. Lao Cai의 많은 지방에서 사람들이 개신교를 믿게 되었고 그 중에는 가족이나 종족 환경에서 강제적 선교도 일어났다. 개신교는 Hmong족의 전통문화뿐만 아니라 Hmong족의 전통 종교, 신앙에도 직접적으로 영향을 주었다. 이 글에서는 Hmong족이 살고 있는 Lao Cai 지방을 선택하여 고찰하며 Hmong족의 전통문화가치에 대한 개신교의 영향 및 원인을 살펴보기로 한다. 먼저 Hmong사람들은 전통신앙을 버리고 개신교를 믿게 되는 원인을 살펴보자. 주 원인은 다음과 같은 네 가지가 있다고 본다. -경제와 관련된 원인 -성별 불평등과 관련된 원인 -학문 수준과 정보 습득 희망과 관련된 원인 -전통문화, 심리와 민속의식과 관련된 원인 그리고 다음과 같은 두 가지 각도에서 전통문화 가치에 대한 영향을 알아보았다. 첫째는 개신교가 Hmong사람의 전통사회체제에 큰 영향을 준 점, 둘째는 개신교가 Hmong사람의 풍속습관 및 전통 신앙에 영향을 준 점이다. 개신교가 Hmong사람의 전통사회체제에 큰 영향을 준 점은 여러 방면에서 보인다. 전통적인 가치와 개신교의 새로운 규정 사이의 충돌도 있고 가족 안에서 부부의 위치상 충돌도 있다. 또한 Hmong사람들에게 전통 종족의 역할, 위치를 약화시키는 영향도 주었고 산골 마을에서 개신교를 믿는 사람들과 믿지 않은 사람들 사이에 일어난 새로운 충돌도 있다 개신교와 개신교의 교리는 역시 풍속습관과 전통신앙에 큰 영향을 주었다. 첫째는 예수의 역할이 가장 중요하고 조상 숭배나 "집에 있는 귀신 숭배"같은 것보다 강력한 것이다. 그래서 Hmong사람의 신앙, 종교는 원시적 다신교부터 일신교로 변한 것으로 보인다. 둘째는 개신교를 믿는 사람들이 Hmong족의 전통 민속축제를 점차 멀리한다. 어떤 경우에는 그 사람들이 자기 민족의 전통문화 환경을 떠나 버리는 일도 있었다. 셋째는 개신교의 교리가 Hmong족의 풍속 규정을 바꾸게 하였고 Hmong사람들이 새로운 종교의 교리를 집행시켰다. 넷째는 인간 인생 주기에 관한 풍속습관 및 민속의례들은 의례 대상보다 의례 주제를 중심으로 삼는 것으로 점차 변화했다. 대체로 개신교가 Hmong족 공동체에 유입하여 이 민족의 전통문화 가치는 변화했다. Hmong족 공동체에 오래 존재해 왔던 낙후한 습관을 개선하는 점에서 개신교는 적극적 역할을 했다. 현재 문제점은 어떻게 전통문화가치를 유지하고 새로운 종교와 같이 존재할 수 있느냐라는 문제이다. 이 문제는 다음 연구 대상이 될 것이다.
