This paper aims to examine the meaning of 'Xuan(玄)' in the cosmogony, especially in the view of Yang-xiong(揚雄) and Ge-hong(葛洪). The concept 'Xuan' is thought to have originated in the XianQin text Laozi & Zhouyi. After the XianQin period, this concept has been defined as philosophical concept, and it has a variety of meanings. This paper discussed about the cause of creation, the differentiation process, and the existence principle, within the cosmogony of Yang-xiong & Ge-hong. First, the cause of creation in the Yang-xiong is efficient cause in the state of the elementary substance, but also is the principle that is applied to the phase of the creation. While the cause of creation in the Ge-hong is comprised of the cause of the creation and the existence principle. Thus, the meaning of the concept 'Xuan' in the both scholar is different from the matter monism. Second, the concept 'Xuan' in the both scholar contains the tendency of cosmogony and ontology. Yang-xiong maintains the cosmogony, but he also hold on the rudimentary view of ontology. While Ge-hong display a tendency of ontology. Third, Ge-hong accepted the view of Yang-xiong and he developed the meaning of the existence principle. And finally, the concept 'Xuan' in the both scholar forms a philosophical system. Yang-xiong insisted that the concept 'Xuan' is the basis of the universe, the human-being and the society. While through realizing the concept 'Xuan', Ge-hong tried to pursue the human-being's agelessness and the eternal life.

This paper aims to help prevent the spread of COVID-19 by analyzing confirmed cases of COVID-19 in Daejeon. A high volume of visitors, downtown areas, and psychological fatigue with prolonged social distancing were considered as risk factors associated with the spread of COVID-19. We considered the weekly confirmed cases in each administrative district as a response variable. Explanatory variables were the number of passengers getting off at a bus station in each administrative district and the elapsed time since the Korean government had imposed distancing in daily life. We employed a mixed-effects zero-inflated Poisson regression model because the number of cases was repeatedly measured with excess zero-count data. We conducted k-means clustering to identify three groups of administrative districts having different characteristics in terms of the number of bars, the population size, and the distance to the closest college. Considering that the number of confirmed cases might vary depending on districts' characteristics, the clustering information was incorporated as a categorical explanatory variable. We found that Covid-19 was more prevalent as population size increased and a district is downtown. As the number of passengers getting off at a downtown district increased, the confirmed cases significantly increased.

This study interpreted a traditional garden of Korea through reception aesthetics. The 'gap' of acceptable aesthetics is found in the 'distance that occurs between writers and readers'. This study aims to interpret this gap between what the writer intends and what the reader expects. Boundaries do not limit traditional spaces in Korea and, therefore, are not limited by characteristics. These characteristics were studied from the perspectives of the author, the work, and the reader. The aspect first looked at the life and ideas of the gardener, the second analyzed the form and structure of the garden, and the last examined writings, from the past and present, of those who appreciated the garden. From the author's perspective, Sosoewon was understood as a garden that embodied the philosophy of Yang Sanbo. Second, the duality and indeterminateness were recognized as two characteristics of this work; artifacts in the garden were arranged in a natural form, and the gardens have indefinite boundaries, so they can be freely expanded and reduced. Finally, from the reader's perspective, it was noted that the beauty of this garden is enhanced through poetry, painting, and writing. Thus, historic gardens of Korea can be open spaces where the meaning of the garden is enriched through the free participation of viewers based on their own ideas.

This study examines the mediating effect of self-directed learning between the self-leadership and academic self-efficacy of beauty major Chinese(CN) students and examines the variables affecting the academic-self-efficacy of CN students. The study aims to obtain basic data to help improve college life in foreign countries. A survey was conducted upon 440 beauty major CN students in universities across Seoul. The results of the study showed differences in self-directed learning according to the number of semesters they have been in Korea and in academic self-efficacy according to their TOPIK levels. Self-directed learning was found to have a partial mediating effect between self-leadership and academic self-efficacy of CN students. These results showed that self-leadership and self-directed learning are major predictors of the academic self-efficacy, which is further reinforced when self-leadership and self-directed learning are promoted together. These results imply that there should be preceding efforts to promote both self-leadership and self-directed learning to increase the self-efficacy of CN students majoring in beauty.

The seriousness of fire is rising because fire causes enormous damage to property and human life. Therefore, this study aims to predict various risk factors affecting fire by fire type. The predictive analysis of fire factors was carried out targeting Gyeonggi-do, which has the highest number of fires in the country. For the analysis, using machine learning methods SVM (Support Vector Machine), RF (Random Forest), GBRT (Gradient Boosted Regression Tree) the accuracy of each model was presented with a high fit model through MAE (Mean Absolute Error) and RMSE (Root Mean Squared Error), and based on this, predictive analysis of fire factors in Gyeonggi-do was conducted. In addition, using machine learning methods such as SVM (Support Vector Machine), RF (Random Forest), and GBRT (Gradient Boosted Regression Tree), the accuracy of each model was presented with a high-fit model through MAE and RMSE. Predictive analysis of occurrence factors was achieved. Based on this, as a result of comparative analysis of three machine learning methods, the RF method showed a MAE = 1.765 and RMSE = 1.876, as well as the MAE and RMSE verification and test data were very similar with a difference between MAE = 0.046 and RMSE = 0.04 showing the best predictive results. The results of this study are expected to be used as useful data for fire safety management allowing decision makers to identify the sequence of dangers related to the factors affecting the occurrence of fire.

Korea has rapidly become an aging society, and this phenomenon is found not only in common population but also in many religious circles. In this context, interest in the welfare of retired clergy members is increasing, and some religious organizations are trying to devise and perform rules and/or policies that ensure a secure post-retirement life for their clergy. However, the welfare benefits differ from one religion to another according to the characteristics of the given religion's organizational structure. For instance, denominations with a centralized hierarchy such as Catholicism or Won Buddhism implement a relatively stable welfare system for their elderly clergy members whereas autonomous denominations like many Buddhist or Christian orders are often found to have somewhat insecure welfare systems. Clergy welfare in Daesoon Jinrihoe, one of the representative new religions in Korea, is emerging as an important issue as Daesoon Jinrihoe is also affected by the problems of Korea's aging society. However, since the order has a mixed system of a centralized hierarchy and autonomous local branches, the welfare for their elderly clergy lacks clear lines of accountability. Consequently, there have been talks to devise a proper welfare system; however, these talks have come to a standstill. In this regard, this study aims to look into and analyze how various structures and welfare systems within Korean religious organizations impact elderly clergy. Lastly, this research will provide suggestions on practical alternatives for Daesoon Jinrihoe which could resolve the problems within their welfare system that negatively impact elderly clergy members at present.

The safe driving reward system aims to reduce the loss of life and property by reducing the occurrence of accidents by motivating safe driving and encouraging active participation by providing direct reward to vehicle drivers who have performed safe driving. In the case of the existing digital tachograph, the goal is to limit dangerous driving by recording the driving status of the vehicle whereas the safe driving reward system is a support measure to increase the effect of accident prevention and induces safe driving with financial reward when safe driving is performed. In other words, in an area where accidents due to speeding are high, direct reward is provided to motivate safe driving to prevent traffic accidents when safe driving instructions such as speed compliance, maintaining distance between vehicles, and driving in designated lanes are performed. Since these safe operation data and reward histories must be managed transparently and safely, the reward evidences and histories were constructed using the closed blockchain Hyperledger Fabric. However, while transparency and safety are guaranteed in the blockchain system, low data processing speed is a problem. In this study, the sequential block generation speed was as low as 10 TPS(transaction per second), and as a result of applying the acceleration function a high-performance network of 1,000 TPS or more was implemented.

Focusing on the concept of "narrative of desire" advocated by Peter Brooks, this paper aims to analyze the construction and presentation of the body narrative in I Am What I Am, combined with the "body situation" concept of Merleau-Ponty, the pioneer of body studies. This paper first analyzes the changes in the characters' physical and mental cognition in the film through the "desire narrative" and "visual body" proposed by body narratologist Peter Brooks. Secondly, this paper summarizes the physical and mental evolution of the coward-rebel-disciple-self-breaker experienced by the teenager, and analyzes the continuous plot composed of the body in time and space through the physical situation formed by time and space, that is, the visual presentation of the juvenile's personal body picture. So the protagonist's physical desire and visual body in "I Am What I Am" are the meta-driving forces of the narrative. The film presents the subject's physical desire in a visual way, and reproduces the deduction process of the body narrative through the body situation.shift from the common surreal, magical special effects, exaggeration, deformation and other techniques of commercial animations such as "Ne Zha: Birth of the Demon Child" (2019) and "Legend of Deification" (2020) to the true-life "I am What I am". "(2021), "To the Bright Side" (2022) and other visual experiences of the same kind marks breakthroughs made by Chinese animation and is of practical significance.

This study aims to explore health behavior profiles and the association between the derived profiles and living arrangement among middle-aged and older adults. Using data from wave 6 (2016) of the Korean Longitudinal Study of Aging, latent profile analyses were applied to identify patterns of health behaviors and multinomial logistic regression models were conducted to predict profile membership using living arrangement (i.e., living alone, living with spouse only, living with family members) and sociodemographic characteristics. A sample of 7,048 respondents aged 55 and older were included in the study. Results revealed that Korean middle-aged and older adults can be grouped into four health behavior profiles: "High health-compromising" (4%), "Moderate health-compromising" (28%), "Low health-compromising" (65%), and "High physical activity" (3%). Also, living arrangement showed significant profile differences. Compared to the respondents living alone, those living with spouse only were more likely to belong to low and moderate levels of health-compromising behavior profiles than the "High physicial activity profile". Respondents living with family members were more likely to belong to the "High health-compromising profile" than the "High physical activity profile" compared to those living with spouse only. These findings indicate that living arrangement needs to be taken into consideration when developing health promoting programs and supports. Moreover, policy interventions suiting the needs of various sociodemographic subgroups are recommended.

This study aims to reveal how a port affects the living conditions of its neighborhood area with a case study of Pusan New Port and to suggest several implications to port policy. PLS-SEM reflective measurement model satisfies the criteria on reliability and validity, and also structural model meets the criteria in terms of R2, path coefficients' significance and predictive relevance(Q2). The results of PLS-SEM support the hypotheses of this study: The expansion of Pusan New Port contributes to the improvement of living conditions of Gangseo-gu(nearby area) through its significant and sequential effects on the employment and population increase of Gangseo-gu. The originality of this study can be found in enunciating that a port plays a role as a driving force of the betterment of living conditions of its nearby Gu-level area. In terms of policy, central and local governments and port related companies should cooperate with each other to reinforce the acceptability of port policy through the improvement of the living conditions of port neighborhood area. To evaluate comprehensively the influence of a port on its neighborhood area, a further study needs to identify how a port affects the quality of life of the area or what kinds of socio-economic effects a port has on the area.
