The modern pentathlon is an exercise in which people and people compete, as well as exercise without equipment, exercise using equipment, and exercise with animals, and it is an exercise that includes static and dynamic exercise. The ethical issues of modern pentathlon athletes are also related to the poor environment and economic reasons, and the athlete's ethical awareness, attitude, and spirit have a great influence on the athlete's mental environment. In this study, the direction of improvement of ethical problems, which are different as important issues in modern sports, was examined, and qualitative research methods were applied to explore the sports spirit and ethics of the modern pentathlon. Correct sports should not deviate from the intended purpose of the exercise or cause or force the athlete to suffer physical or mental pain. In sports, compensatoryism can be a direct cause of improved performance or record-breaking, but sometimes it can also cause distorted athletes. Air doping has ethical issues that can cause controversy over the health or fairness of athletes, mental and physical damage to athletes, and harm. Responsibilities and ethical issues of athletes who take prohibited substances or leaders or supervisors who neglect or encourage them should be treated as very important matters. In the sports field, the reward system that is subordinate to the athlete's or leader's performance is related to the athlete's or leader's livelihood. For a fair and just game progression, it is necessary to break away from the development of athletes who are only focused on performance. The problem of Unethical issues must be overcome by emphasizing the restoration of ethics that are reasonably recognized in ideology and logic.

The non-face-to-face environment accelerated by COVID-19 has speeded up the dissemination of digital virtual ecosystems and metaverse. In order for the metaverse to be sustainable, digital twins that are compatible with the real world are key, and critical technology for that is AR (Augmented Reality). In this study, we examined research trends about AR, and will propose the directions for future AR research. We conducted LDA based topic modeling on 11,049 abstracts of published domestic and foreign AR related papers from 2009 to Mar 2022, and then looked into AR that was comprehensive research trends, comparison of domestic and foreign research trends, and research trends before and after the popularity of metaverse concepts. As a result, the topics of AR related research were deduced from 11 topics such as device, network communication, surgery, digital twin, education, serious game, camera/vision, color application, therapy, location accuracy, and interface design. After popularity of metaverse, 6 topics were deduced such as camera/vision, training, digital twin, surgical/surgical, interaction performance, and network communication. We will expect, through this study, to encourage active research on metaverse AR with convergent characteristics in multidisciplinary fields and contribute to giving useful implications to practitioners.

This study aimed at investigating the validity of WHR (or waist-to-hip ratio) and Golden ratio as standards of physical attractiveness. Each of 60 male and 60 female college students were divided into two groups of 30. Using the 3D game program, each person in one group drew a physically attractive figure of the opposite sex while the other group drew a physically attractive figure of the same sex. Then, WHR and Golden ratio of the figures were measured and compared with the ideal WHR (.7 for women and .9 for men) and Golden ratio 1.618. It was found that WHR and Golden ratio for the physically attractive figures were lower than the ideal standards regardless of the participant's gender. That is, the participants preferred to men and women having curvaceous body shapes with a narrow waist and a wide pelvis. In most cases, Golden ratios measured in many ways were not correspondent to the ideal ratio, 1.618. In regards to BR (or Body Ratio), the legs and waist of the physically attractive figures were shorter relative to the Golden ratio and this was more salient for physically attractive man figures. Regarding the facial ratio measured by FR(or facial ratio) and FR_VP(or facial ratio_vertical point), the faces of figures made by participants, regardless of their sex, were shorter and wider compared to the Golden ratio. Further, the participants preferred baby-faced woman and masculine man figures. Finally, implications of the findings, limitations the of the present study, and the suggestions for future research were discussed.

Now Venezuela is the most attentional country in Latin America not only in our country but also all world. Unfortunately, the current crisis is a danger that threatening the venezuelan people's right to live, so most of the news is negative. Some analysts in Korea insist that everything is the result of invasion by US imperialism, others say it is a state of default due to excessive populism. The others also described as a power game of the powers of the world by the new Cold War. But most essential thing is that Sovereign of Venezuela, Venezuelan people are marginalized in this process. Venezuela's crisis seems to have been both a combination of internal and external factors, but internal factors been a main cause. The internal factors are the dictatorship and corruption of crony capitalism of nepotism which are considered historical ailments in Latin America. Chávez criticized the oligarchy, but paradoxically, the Chávezian or current ruling forces became another oligarchy. Unfortunately, Western powers such as the United States and the EU and Venezuela's current ruling powers are at an extreme confrontation, so can be seen using cliff-edge tactics. The best solution is the free and peaceful reelection of the president. After the patriarchal winter, which spring will come the Venezuelan people must decide.

This paper establishes and propagates the value of the play through the study of the transition process of the yesan play from 1920 to the present, presents an alternative through the unique theatricality of the region and aims to activate it. The theater divided the theater into Yecheon, Chungnam Theater Festival, and Youth Theater Festival, which are currently active, and focused on Yedang International Performing Arts Festival, which is the only one in Yesan. The details of the performance due to the loss of data were not specified as much as possible, but the contents of the yesan play before 1990 were reviewed using the eupji and Myeonji. It also starts with a lack of diversity in plays in the developing direction of Yesan. Children's plays should be dismissed for simple commercial purposes, or the value of traditional Korean plays should be compared to Western ones, to promote the development of local plays through the natural characteristics and the basis of traditional culture, and to sustain the continuity of extreme economic performance and performances through the development of repertoires. Infrastructure deployment can be cited. The in flow of specialized actors and the use of art administrators creates a stable theater environment and activates the reeducation of local actors to promote theatrical imagination. It is also an urgent task to develop a new theatrical form by introducing experimental theatrical methods of young artists in the overseas performance business of theater troupe Yechon. Finally, Yedang International Performing Arts Festival should be characterized and differentiated from other festivals.

Urban rivers and their surrounding environments have been altered due to factors such as rapid economic growth and urban development. This alteration have caused the rivers to lose their original value and become exposed to various pollution, resulting decrease in citizens' quality of life. This study aims to estimate citizens' Willingness To Pay (WTP) for water quality improvement in Suyeong River in Busan. To estimate the non-market value of the Suyeong River, the WTP of Busan citizens for water quality improvement was estimated, applying Contingent Valuation Method (CVM). The WTP for improving the water quality from Grade 4(polluted water) to Grade 2(game fish like bass can live in it) was estimated using the water quality ladder concept of the US Environmental Protection Agency, assuming annual donations for five years. For the CVM, the logistic distribution and Spike Model were adopted. As a result, citizens residing in the surrounding area of Suyeong River expressed a higher WTP. Considering more than half of the Busan citizens are aware of the "conservation of nature and ecosystems" as a major function of the Suyeong River, this higher WTP could serve as a basis for improving the value of urban rivers.
