With the signing of the China-Korea FTA agreement, it is of great practical significance to study the potential of electronic product trade between China and South Korea under the new situation to promote the development of electronic product trade between the two countries. Based on this, this paper selects the data related to the trade of electronic products between China and South Korea from 2005 to 2019. First, it analyzes the factors of the trade potential of electronic products between the two countries by building a trade gravity expansion model, and then calculates and compares the electronic products between China and South Korea. trade potential. The research results show that: (1) The economic scale, population scale and APEC member countries have a promoting effect on the trade volume between China and South Korea. The geographical distance has an inhibitory effect on the trade volume between China and South Korea. Trade freedom has a significant misuse of promotion for China's electronics trade, while it has no significant effect on South Korea's electronics trade. (2) After 2015, China's electronic product export trade potential to South Korea is huge. There is also a certain potential in South Korea's trade in electronic products with China, which needs to be explored with active policies.

South Korean law strictly prohibits engagement in medical activities by non-medical practitioners. In the country, tattooing is classified as a medical practice, and non-medical practitioners who engage in it are penalized because they are unauthorized to carry out this procedure. In reality, however, people rarely seek tattooing services from medical personnel. Arguing that their freedom of job selection is violated, non-medical personnel who make a living as tattoo artists reject the characterization of the procedure as a form of medical treatment and demand the decriminalization of tattooing by non-medical practitioners. Nevertheless, tattooing can cause health- and hygiene-related dangers when it is not performed by medical professionals because it involves penetration into the skin using needles. Hence, stringent management is necessary for infection prevention. The gap between reality and the law gives rise to the need for proactive thinking about the institutionalization of tattoo practice by non-medical personnel. Policymakers should reflect on the fact that only minimal tattooing services are currently performed by medical staff while also accounting for health and safety. On this basis, this study examined tattoo-related legislation in South Korea to determine whether the procedure corresponds to medical practice and identify ways to solve problems that occur from the perspective of health care. As a response that promotes safety and reflects reality, this research proposed a three-phase approach.

This paper presents an improved computational framework for the direct-solution-based finite element tearing and interconnecting (FETI) algorithm. The FETI-local algorithm is further improved herein, and localized Lagrange multipliers are used to define the interface among its subdomains. Selective inverse entry computation, using a property of the Boolean matrix, is employed for the computation of the subdomain interface stiffness and load, in which the original FETI-local algorithm requires a full matrix inverse computation of a high computational cost. In the global interface computation step, the original serial computation is replaced by a parallel multi-frontal method. The performance of the improved FETI-local algorithm was evaluated using a numerical example with 64 million degrees of freedom (DOFs). The computational time was reduced by up to 97.8% compared to that of the original algorithm. In addition, further stable and improved scalability was obtained in terms of a speed-up indicator. Furthermore, a performance comparison was conducted to evaluate the differences between the proposed algorithm and commercial software ANSYS using a large-scale computation with 432 million DOFs. Although ANSYS is superior in terms of computational time, the proposed algorithm has an advantage in terms of the speed-up increase per processor increase.

With the advent of the post-COVID19 era, people must maintain social distancing to quarantine. However, this rule deprives people of freedom. Therefore, this study proposes a new normal plan for urban park design using drive-thru to recreate space for people to maintain and enjoy their previous lives while complying with quarantine rules. Olympic Park has a large floating population, and is one of the places where drive-thru is available. Therefore, the study designed this place to be the only cafe that could be operated if other cafes were shut down due to social distancing. The cafes in the park were designed into five spaces based on Olympic Park's flag motifs. The results were as follows. The cafe's name is CUPPY (Cup+Coffee), while each logo letter is expressed using the colors of the Olympic flag: blue, yellow, black, green, and red. The cafe spaces were divided into five continents (Europe, Asia, Africa, Oceania, and America), as symbolized by the Olympic flag, with the driving route shaped like the Olympic logo to match the five spaces. Human beings need change and adaptation in various fields to live in a post-COVID19 era that they have never experienced before. Just as the New Normal changes with time, and should, research is essential for presenting a New Normal in urban park design that reflects this disaster situation following the COVID-19 crisis. On this very point, we expect that this research will serve as a reference for urban park design. Additionally, it is believed that continuous suggestions and research will be necessary to apply the model to more diverse environments.

This study aimed to empirically analyze the effect of the appreciation of artwork in the workplace on creativity. To this end, two virtual workspace images with and without artwork were created, and an online survey was conducted with office workers. A regression analysis was performed on the results to investigate whether and how much the appreciation and recognition of artwork was effective for the creativity. As a result, among the factors of recognition according to the appreciation of artwork, "intellectual development" and "thinking" showed positive effects on the five sub-factors of creativity at work, such as original flexibility, alternative problem-solving skills, pursuit of adventure and freedom, individual independence, and exploratory immersion. Unlike most previous studies, however, "understanding" had a negative effect on original flexibility. In conclusion, it was found that some of the factors of the appreciation and recognition of artwork had a positive effect on creativity at work. This study provides implications that the appreciation of artwork in the workplace is effective for improving creativity at work and that it is important for each company to develop a streamlined approach based on its goal of pursuing a creative environment. In addition, it is expected that this study will contribute to the widespread use of artwork sharing services at workplaces as well as encouraging more empirical studies to be done on the effect of the services.

This article dealing with the political participation of Argentine Conservative Protestants tried to examine the effect of such political participation on democratic values and order. To this end, it focused on the subject of religious equality and freedom, and issues of same-sex marriage and sex education. First, the demands of the Protestants, who insisted on the equal treatment of all religions by correcting the religious discrimination policies, a legacy of the colonial era and the military regime, are very natural and self-evident, when we presuppose the value of a democratic society based on political equality and human rights. It can be said that it has contributed to the democratization of society by aiming to solve the old problems of society. But when it comes to same-sex marriage and sex education, things are quite different. Without considering the social situations of the socially disadvantaged or minorities, or the legislative purpose of defending their rights, they insist on only their teachings of scriptures or ethics, even within Protestantism, there is a disagreement on interpretation. These theocratic views and exclusivist attitudes can seriously infringe on the human rights or freedoms of people of different religions, or different choices about marriage or sexuality, among other things. It can be a serious threat to democratic order and values.

A variety of the approaches to the unification of the South Korea and North Korea have been implemented based on both the view of the national-centered unification and that of the reunification of the South and North Korea as a unit of nation through political, economic, military and diplomatics. A culture itself plays a significant role for people to understand one another through communicating and sharing cultural values. At this point, Korean-Wave called'Hallyu' should have various meanings and values for the reunification of South and North Korea. It has been expanded to the world beyond Asia as an icon of the culture. In this situation, North Korea is not exceptional. In other words, North Korea should be influenced by the Korean wave. Sharing a cultural value about Korean-Wave between South and North Koreans would be a way to speed up the reunification by having a common sense about the national identifications. The culture of Hallyu reflecting on the national identification could be helpful to enhance national pride and play a part for curing for the scarlet letters that they have got since the Korea was divided by two parts. The North Korean government's distorted policy to have blamed for the South Korean governing would be challenged if the Korean-wave would be epidemic in the Korean peninsular. In addition, if the North Koreans would be perceptive to the real freedom and universal value for the humanity, it would be more feasible for two Koreas to be reunified than before. In fact, it must serve as a catalyst for the reunification, two Koreas experiencing the Korean wave as a cultural value. As a result, the reunification for the people should have a meaning of the universal value as like everyone in the world can pursue for their own happiness. Through the Hallyu, That is, the change of the people's perception to the reunification will facilitate the reunification of two Koreas more than we expected.

Background: Surgical repair of partial anomalous pulmonary venous return (PAPVR) to the superior vena cava (SVC) using the Warden procedure has favorable outcomes. However, there remain some concerns after the Warden procedure, such as sinoatrial nodal dysfunction and systemic or pulmonary venous stenosis. We investigated the outcomes of the Warden procedure for repair of PAPVR to the SVC. Methods: This retrospective study included 22 consecutive patients who underwent the Warden procedure for PAPVR between 2002 and 2018. The median age and body weight at operation were 27.5 months (interquartile range [IQR], 5.0-56.8 months) and 13.2 kg (IQR, 6.5-16.0 kg), respectively. The median follow-up duration was 6.2 years (IQR, 3.5-11.6 years). Results: There were no cases of early or late mortality. No patients had postoperative heart rhythm problems, except 1 patient who showed transient sinoatrial nodal dysfunction in the immediate postoperative period. Procedure-related complications requiring reintervention occurred in 5 patients, including 3 of 4 SVC stenosis cases and 2 pulmonary venous stenosis cases during follow-up. The rate of freedom from reintervention related to the Warden procedure was 75.9% at 10 years. Conclusion: In cases requiring extension or creation of an atrial septal defect to achieve a sufficient venous pathway, or interposition of an entire circumferential conduit between the SVC and right atrium due to the shortness of the SVC in the Warden procedure, stenotic complications of the venous pathway occurred. Careful observation of changes in the pressure gradient or anatomical stenosis is required in such patients.

This study is a qualitative case study of secondary science teachers who are doing educational activities in YouTube. In particular, this study attempts to interpret this case based on Foucault's concept of 'Heterotopia', which means a space that allows for private freedom or deviance by reflecting various utopias without the norms and constraints from every day or real space. Five secondary science teachers who voluntarily opened a personal channel on the YouTube platform and actively uploaded their own videos related to science education participated in the study. In order to understand the experiences of five secondary science teachers, data were individually collected through semi-structured in-depth interviews, and the collected data were analyzed using qualitative case study method. For valid interpretation of the study, we also referred to the video contents, teacher training materials, and teaching and learning materials produced by the participants. As a result of the study, seven themes were revealed: 'Desire for one's own unique educational activities,' 'Youtube as an extended classroom space,' 'Expanded network of relationships beyond the classroom barrier,' 'Satisfaction of desire for recognition and experience of identity as a YouTuber,' 'Tension between the educational space and the YouTube,' 'Space to be reborn as a craftsman,' and 'Finding one's own direction as a Teacher-YouTuber.' Given those findings, we found that the identity and desire of secondary science teachers, which were limited in the existing secondary schools and classrooms, was expanded in a new space called YouTube. In addition, we suggested that YouTube could be a space where science teachers can realize their own ideals and feel the joy. And simple regulating teacher's behavior in Youtube space only based on norms and standards shared in traditional educational space would rather hinder their healthy construction of identity and growth.

It has been noted that an accurate estimation of wind loads on offshore structures such as an FLNG (Liquefied Natural Gas Floating P roduction Storage Offloading Units, LNG FPSOs) with a large topside plays an important role in the safety design of hull and mooring system. Therefore, the present study aims to develop a computational model for estimating the wind load acting on an FLNG. In particular, it is the sequel to the previous research by the author. The numerical computation model in the present study was modified based on the previous research. Numerical analysis for estimating wind loads was performed in two conditions for an interval of wind direction (α), 15° over the range of 0° to 360°. One condition is uniform wind speed and the other is the NPD model reflecting the wind speed profile. At first, the effect of sand-grain roughness on the speed profile of the NPD model was studied. Based on the developed NPD model, mesh convergence tests were carried out for 3 wind headings, i.e. head, quartering, and beam. Finally, wind loads on 6-degrees of freedom were numerically estimated and compared by two boundary conditions, uniform speed, and the NPD model. In the present study, a commercial RANS-based viscous solver, STAR-CCM+ (ver. 17.02) was adopted. In summary, wind loads in surge and yaw from the wind speed profile boundary condition were increased by 20.35% and 34.27% at most. Particularly, the interval mean of sway (45° < α <135°, 225° < α < 315°) and roll (60° < α < 135°, 225° < α < 270°) increased by 15.60% and 10.89% against the uniform wind speed (10m/s) boundary condition.
