The mycelia were directly isolated from eight species of fungal basidiocarps, confirmed to the ectomycorrhiza in the roots from the fields(forestry); Suillus bovinus, Paxillus involutus, Lactarius hysginus, Russula fragilis, Lepista nuda, Lyophyllum shimeji, Tricholoma matsutake, and Russula integra. The mycelia were pure-cultured with several transferring in various agars, and inoculated to the roots of pine(Pinus densiflora) seedling by in vitro method. After ten months growth under artificially aseptic conditions, all pine seedlings inoculated were stimulated at the growth-height, whereas those not inoculated were nearly dead. Also, the ramifications of ectomycorrhizal pine roots formed in the synthetic in vitro systems and were various according to the different mycelia. Synthesis of ectomycorrhiza were clearly confirmed in ten months growth, but not distinguished at this moment. It was clearly proved that the mycelia isolated caused the ectomycorrhizae in the roots of pine seedlings.

Differential display of reverse transcription(DDRT)-PCR was conducted to have a profile of the differentially expressed genes during the formation of fruiting body of Lentinus edodes. The lines of L. edodes(ImHyup-1) employed were cultivated in the artificial blocks of sawdust, and the fruiting body was induced from the mycelia or the mass protruded from the brown surface of the sawdust blocks. RNAs were prepared from the four different developmental stages; mycelial, primordial, and stipes and pileus of fruiting body. The fragments of cDNA were synthesized from the combinations of the arbitrary primers and 3' one anchored Oligo-dT primer. Twelve combinations using the primers have been tested, and among them nineteen bands were identified as differentially expressed. Those genes were further analyzed by DNA sequencing and followed by homology search. Characterization of one clone was conducted as a preliminary data and more are under investigation.

Today, computational thinking takes an important role in problem solving in software education. As a result, software education as liberal arts for non-CS major students is rapidly expanding. It is necessary to study the effects of computational thinking on software problem solving ability compared to traditional programming language education. In this paper, we propose an evaluation model for analyzing the effects of computational thinking on the overall software development process, and analyze how the problem solving process is different for learners who take computing thinking classes and programming language courses as liberal arts courses. As a result, students who learned computational thinking showed higher ability in problem analysis and design process.

In this paper, we propose a reasonable plan for university information education by examining whether university students' academic performance improves when the information mind is satisfied. In particular, through comparison between physical education students and general students, it was intended to provide empirical help in preparing strategies for information education in universities in the future. As a result of the analysis, there were some differences by major category, but overall, the information mind improved major convergence ability, teamwork and self-directed learning ability, and academic performance. Therefore, in order to improve the Information mind of college students, it is suggested that the need for Information should be recognized and the curriculum and program suitable for the major characteristics should be introduced and implemented.

The purpose of this study is to identify the difference between the current retention level and the required level of engineering students' career competency that they think they need based on their perceptions. Ultimately, the results of this study are used as basic data when designing the major/general education program and the curricular/extra-curricular career program. The task of this study is to identify the difference between the current retention level and the required level of engineering students' career competency. And based on this, it is to confirm the educational needs of engineering students for the career competency. For this purpose, literature research on career competency education in universities was reviewed in the theoretical background. Next, previous studies on career competency and sub-competence derived from career competency-related studies and detailed questions were analyzed. Based on this, an initial evaluation tool for career competency of engineering students was developed. Finally, through expert review, a career competency evaluation tool with a total of 43 items in 10 competency groups was developed. A career competency evaluation questionnaire was conducted for 197 engineering students who participated in the 2022 Engineering Education Festa, and as a result of the IPA analysis, 'global competency' was found to be the competency with the largest difference between importance and execution. Next, 'major job competency' and 'career development competency' appeared in order. Reflecting the results of this study, it is expected that mutually organic design of competency-based liberal arts curriculum and major curriculum that can cultivate global competency, major job competency, and career development capability will be carried out through learning activities and field practice.

The purpose of this study is to develop convergence major-based learning (CMBL), which selects performance tasks related to local problems at hand and solves them based on convergence major performance, and builds a suitable teaching and learning model. We developed a CMBL class with a team project-type class that finds and solves practical problems in the region to cultivate overall problem-solving capabilities for convergence major competencies. Additionally, for this class, the instructor played a role as a bridgehead to explore and connect the community's sites, and students visited connected institutions in person to identify problems they need based on understanding and empathy for the subjects through field observation and qualitative interviews, and developed a CMBL class teaching and learning model necessary to directly solve them by using their major capabilities to the fullest. Therefore, we intend to present the future-oriented direction of university convergence education required by the community by forming a group of students with various majors to cultivate the ability to solve realistic problems in the community.

This study was conducted to reduce sodium (Na) intake and to establish healthy dietary lifestyles of children. To achieve these goals, we searched, collected, and analyzed the materials related to the Na education, based on which the research personnel-professors and graduate students in nutrition and child education and elementary school teachers discussed to figure out major topics, objectives, and detailed contents and activities appropriate for Na intake reduction. Also a survey was done on the sodium intake and nutrition knowledge of the elementary students. We also organized an advisory committee composed of 15 professionals in related fields to discuss the adequacy and validity of the specific contents. Finally, we systematically organized the contents and developed children's textbooks and teacher's guidebooks. Considering the different cognitive development stages of junior and senior elementary students, we developed two different textbooks for each of them which are easy to read and understand, fun to play with lots of activities, and designed to practice into daily life. The contents cover three major topics-the concept of Na, Na in food, Na in life and are composed of 6 units in total. To help teachers understand and instruct, teacher's guidebook contains an overview of the education, specific information and practical guidelines for each class. We developed these education materials with the aim of lowering children's Na consumption and eventually promoting their health welfare; hopefully we expect these materials would be useful for children's nutritional education in the field.

Engineering Colleges in Korea have two educational objectives: 1) strengthening of speciality 2) cultivation of the engineering literacy such as the ability of working together, the ability of communication and creative thinking. In order to achieving these objectives, Engineering Literacy education was originated. The improvable proposal of general education course of engineering college is divided into two parts. One is American type that emphasizes on the general education independently of major. The other is Korean ABEEK's type that attach importance to engineering literacy. This study researches the case of Seoul National University that applied ABEEK's engineering literacy on redesigning the curriculum. To redesign the curriculum, college of engineering, Seoul National University reduced the optional courses in general education and had the students complete the engineering literacy. This device is effective, because it is able to keep the universal general education and make the most of major's characteristics.
