In order to evaluate the usefulness of metaverse learning from the learner's point of view, this study 1) evaluated whether the expectancy-value of the class was satisfied before and after the learner used the metaverse learning platform and 2) verified factors affecting metaverse learning satisfaction with regard to the self-efficacy and expectancy-value of learners. Expectancy-value was evaluated by the learning effect, communication, class involvement, and learning attitude, whereas self-efficacy was evaluated by preference for task difficulty, self-regulation efficacy, and self-confidence. As a result of a study targeting 70 college students who applied for a few courses using the metaverse platform at a university in the northeastern part of Seoul, learners were found to have high expectations and values for learning before using the metaverse platform, but both were not statistically satisfied after use. In addition, the higher the self-efficacy of the learner, the higher the satisfaction with the metaverse learning, and statistically significant results were found in the task-difficulty preference and self-regulatory efficacy among the sub-factors of self-efficacy. There is a negative causal relationship between expectancy-value factors and satisfaction with metaverse learning. This study implies that it is a learner-centered evaluation of metaverse learning, revealing the expectancy-value effect and factors influencing the satisfaction with metaverse learning.

The reports on the chemical composition of developing job's tears seeds is very insufficient by this time. The purpose of this study was to obtain the fundamental information on chemical component of the developing job's tears seed, including starch, sugar, oil, protein, fatty acid, Alkali Digestibility Value(ADV), 100-grain weight. Two job's tears varieties in different by maturity types were analyzed for those components from 10 days after heading to maturity, with 5-day intervals. Total sugar content in seeds followed a pattern of linear increase after heading, but it started to decreased around 15 days after heading. On the other hand, starch content continued to increased until maturity and the highest increasing occurred between 15 and 20 days after heading. The protein content of seeds was decreased, while oil content was increased through the ripening process. Starch content showed a positive correlation with 100-grain weight, ADV, oil and germination percent, but it had negative correlation between total sugar and protein contents in ripening process. Maximum starch content, 100 grain weight, and germination percent obtained by quadratic equation were attained 38 to 43 days after heading. So that the physiological maturity of job's tears seeds was considered to be 40 days after heading.

The study was conducted to investigate some grain quality characters related with brewing fittness for rice wine by adopting eight rice varieties as materials. Six japonica rice varieties except two Tongil-type rice had short and round grain of 1.80 or lower grain length/width ratio. 1000-grain weight of brown rice was 21.7~29.5g of significant difference among varieties. The white-center of rice grain was most severe in Hidahomare and Iri 402. Among tested varieties, Seomjinbyeo, Iri 402, Dongjinbyeo and Hidahomare had 50% or higher head rice ratio, while the others had relatively worse milling properties resulted from higher ratio of notched-belly and broken grain. Chemical components and total acid and amino acid content of refined rice wine was relatively good in every variety. Liquifying and saccharificating power was higher and koji conditon was also good in the varieties of high head rice ratio. Seomjinbyeo, Dongjinbyeo and Iri 402 was preferred in sensory test of refined wine and was recognized as superior adaptable rice varieties for brewing rice wine.

Recently, China-Taiwan relations are facing a crisis, and at the same time, the U.S.-China relationship and the structure of Northeast Asia are greatly shaken, so we should pay attention to changes in cross-strait relations. This study aims to predict how cross-strait relations will change after the party convention by analyzing Xi Jinping's Taiwan policy, focusing on the "Political Report" of the 20th party convention and the content analysis of leadership personnel. The results of the study are as follows. First, as the amendment to the party constitution announced after the closing of the party convention stipulates the possibility of armed invasion, Xi Jinping will implement a tough Taiwan policy emphasizing unification. Second, strategic competition with the United States will continue to intensify in the future when analyzing the contents of Chapters 2, 11, 13, and 14 of the "Political Reporting" and the personnel management of diplomatic and security leadership. As a result, cross-strait relations are expected to show instability for a considerable period of time. Third, at a time when Taiwan rejects the unification plan of "one country, two systems" and the tendency to de-Chineseize is strengthening, there is a possibility that legislation or specific enforcement ordinances will be enacted to strengthen the existing "Anti-Secession Law." Fourth, it is expected that strong and warm two-sided strategies will be used together, such as taking a strong response to external forces interfering with the Taiwan issue and Taiwan independence forces, and using incentives for the Kuomintang(KMT) and Taiwanese who are friendly to unification.

The present study examines the transnational "Hallyu" (the Korean wave) phenomenon after the 1990s in the context of a solidarity movement of East Asian women. It also focuses on the passion for the world stage given the cultural industry was supported by the government as a "chimney-less factory" during the IMF financial crisis. Over the past twenty years and through Hallyu 1.0, Hallyu 2.0, and Hallyu 3.0, "K-entertainment" has been advocated, as a concept that encompasses K-drama, K-pop, etc. in the cultural industry. Furthermore, everything Korean, through K-culture, is being put at the forefront. However, there is insufficient discussion regarding the actions of the women who led the Korean wave. This paper examines the female fans and girl groups who played leading roles in the rise of popular culture and its transnational prominence within the context of the female agency and female labor involved. The lack of acknowledgment of their roles is linked to the current erasure of the discussion on the female youth. Discussion on "woman" is still limited to the domain of reproduction in the generational discussion that has replaced the existing nation-state or class led discussions in the current era of neoliberalism. However, since The reboot or the popularity of feminism in recent years, the interest in the female narrative, in works such as 'Kim Ji-young, Born 1982' has been expanding beyond East Asia to the rest of the world. Just as Hallyu was created by women in the beginning, there is a new trend in which women across national borders are joining in solidarity. As such, the present study attempts to prove that the female fan, girl group, and female youths must be one meta-narrative through a feminist reading, rather than individuals with separate identities.
