The purpose of this study is to increase the development possibility of K-pop music by analyzing K-pop music and analyzing the use of world music in it. As a research method, we will first look at the world music elements Puerto Rico's reggaeton, Jamaica's toasting, and the melody of Indian music. After that, we analyze two songs, Hyo-yeon's and Hyun-A & Dawn's , with rhythm and melody elements to find out the utilization of World Music. As a result of the study, it was found that it rhythmically showed the type of Dembow rhythm derived from Puerto Rico's reggaeton, and melody followed the form of Jamaican toasting and the melody of Arabic music. This study is meaningful in presenting the possibility of development and various directions of K-pop in the future by analyzing the use of world music used in K-pop music. Through the convergence of various world music and K-pop, I hope that K-pop music will become a culture that is supported by a wider public.

With the development of industry, fine dust is causing difficulties in various fields such as environment, health, and life, and a large amount of pollutants generated from human social activities are emerging as a serious environmental problem due to air pollution. Therefore, in this study, activated carbon was added to remove fine dust and volatile organic compounds by spinning cellulose acetate polymer fibers on a silicon support using the electrospinning method. By varying the activated carbon ratio and electrospinning time, the fine dust blocking effect and toluene adsorption performance were confirmed according to the activated carbon ratio and filter thickness. As a result, it was shown that the particles were effectively blocked with the increase in the electrospinning time due to the filter thickness increase. Adsorbed amount of toluene was increased with increase in activated carbon amount. Light transmittance was decrease with increase in electrospinning time, showing that there were light transmittance in filters electrospun for 20~30 minutes.

Purpose: This study aimed to construct a structural equation model to explain and predict factors affecting the health-related quality of life (QoL) in female rheumatoid arthritis (RA) patients based on the health-related QoL model by Ferrans et al. (2005) and a literature review. Methods: Patients (N=243) who were either registered members of an internet cafe composed of patients with RA or rheumatology outpatients at two tertiary general hospitals in Busan, Korea, were recruited via convenience sampling. Data were collected from July 2 to September 9, 2021, and the survey was conducted using a web-based questionnaire. The data were analyzed by SPSS and AMOS 26.0. Results: The goodness-of-fit statistics of the final model exhibited good results (χ²/degree of freedom=2.68, Turker-Lewis index=.94, comparative fit index=.96, standardized root mean-squared residual=.04, root mean- square error of approximation=.08), and 11 out of 14 paths of the model were supported. The squared multiple correlation, which reflected the explanatory power of the environmental characteristics, symptoms, functional status, and perceived health status on health-related QoL, was 80%. In the hypothesis model, 10 paths had significant direct effects, 6 paths had significant indirect effects, and 12 paths had significant total (direct and indirect) effects. Conclusion: Considering that factors directly affecting the health-related QoL of female patients with RA were social support, symptoms (fatigue and depression), resilience, and perceived health status, and that resilience was the most influential factor, clinicians can encourage resilience. Hence, to improve the health-related QoL of female patients with RA, continuing management is necessary, using various intervention methods that focus on enhancing resilience from the early stage to the end of treatment for RA.

This paper reports on a study testing a model of relationship quality in the context of new versus mature export-import relationships. The model posits that perceived similarity, relationship performance, and opportunism predict relationship quality, moderated by relationship duration. The model also posits relationship quality affects commitment. A survey of importers with regard to their relationships with foreign exporters was conducted to test the model. It has been found that perceived similarity has a significant effect on relationship quality at the early stage of the relationship, but not at the later stage of the relationship. It also has been found that relationship performance and opportunism have significant influence on relationship quality. Regardless of relationship duration, the study results provided good support for our model. Theoretical and managerial implications of the study results are discussed.

The King George Island, where the King Sejong Station is located, represents one of the gateways to the Antarctica from the point of its geographical aspect. It also serves as an advanced post, and plays an important role in the extending for Korea's Antarctic research activities. The existence of maps is not only a basic element for the constructing geographic informations supporting these activities, but also an implied way of announcing the sovereignty over the KingSejong Station in global world. However, the precise surveying for the geographic information has not been carried out, and thus topographical maps as well as geographic information assuring enough accuracy are still missed in this area. This fact had forced Korea to rely on using maps produced by foreign countries. Therefore, this study aims to generate digital topographical maps of 1: 5,000 scale for the constructing geographic information using lightweight aerial photogrammetry system first. And further, it will contribute to offer practical base data for the future research related to the Antarctic environment through the analysis of glacier retreat and change using this new digital map comparing with existing one.

Although the Korea National Guard(KNG) has a short history, it has a great meaning in that it is the first of the Korean reserve forces system. Research on the KNG has been passively conducted so far. Even so, the research conducted was limited to a fragmentary description from a historical point of view and did not identify the characteristics of the KNG. Therefore, in this study, after examining the background of the times when the KNG existed, we tried to identify the characteristics of the KNG from a new perspective from legal, institutional, military, and political perspectives. In summary, the KNG was born as an efficient system in preparation for war while receiving legal support. In addition, the adoption of the volunteer army system, a recruiting system of advanced countries, the fact that officers were trained through a separate military academy unique to the KNG, and that they contributed to rear area operations are highly evaluated from a military standpoint. On the other hand, it is negative that politicians and non-military groups colluded from the process of establishing the KNG. Finally, with this study as an opportunity, it is hoped that research on the reserve force that existed before the Korean War will become more active.

The impact of environmental, social and governance (ESG) performance on investors' decision-making is growing. Investors' focus on the financial performance of firms in the past is expanding to the non-financial performance of the interests of stakeholders surrounding firms. Against this backdrop, this study conducted a panel regression analysis on firms evaluated by Korea Corporate Governance Service to analyze the impact of ESG performance, a firm's non-financial performance, on firm risk. According to the analysis, ESG performance has a negative (-) effect on all three firm risks (systematic risk, unsystematic risk, and total risk), indicating that the stakeholder theory and risk management theory are supported. The implications of this study are: First, ESG reduces not only unsystematic risk but also broad and indiscriminate systematic risk; Second, investors can reduce the risk of their investment portfolio by executing ESG investments; Third, companies can achieve stable financial performance even in adverse circumstances by utilizing the insurance function of ESG management; Lastly, the government can enhance the stability of the financial market while improving the financial soundness of firms through reasonable ESG-related regulations.

The excellent load transfer at transverse joints ensures the high performance of jointed plane concrete pavements(JPCP). Load transfer efficiency(LTE) is affected by dowel-bars, aggregate interlock and types of underlying layers, and these factors have to be modelled adequately for a reasonable analysis of JPCP. Generally, the joint stiffness has been represented by a spring model for the shear transfer by aggregate interlock or dowels. However dowel-bars, aggregate interlock and types of underlying layers have not been considered together in the design of joints. In this study, the joint stiffness that considered those factors was presented by comparing LTE obtained using FWD(Falling Weight Deflectometer) with theoretical results obtained using the finite element analysis. In addition, the effects of temperature and concrete age, on the joint stiffness were investigated.

Although there are many studies on the retirement recently, very few studies have empirically addressed on mandatory retirement. In Korea, several scholars suggest that the seniority systems may be the main reason that employers have been reluctant to hire older workers. Therefore, the seniority system that Lazear(1979) proposed has significant implication on explaining mandatory retirement in Korea. Thus, this study aims to examine the seniority system that Lazear proposed can explain the retired employees' mandatory retirement. The empirical study is based on Korean Longitudinal Study of Ageing. wave I-II. The main result from this analysis is that interaction between wage and job tenure on mandatory retirement is statistically significant. For employees with high wage growth rates, the probability of mandatory retirement rate is higher as their job tenure is longer. On the other hand those employees with wage growth rates, that is lower although their job tenure is longer. This study supports the assertion of Lazear(1979).

The objective of this study is to examine the trend of real earnings for TANF leavers. Using administrative data in Wisconsin, this study tracks the 1998 TANF leavers over 7 years. Based on the cyclicality of real wage hypothesis, this study finds: First, although the average real quarterly earnings of TANF leavers have remained stable since their exits, there are substantial labor mobility among TANF leavers. Second, the panel data analysis shows that the real earnings of TANF leavers are significantly associated with local labor market conditions, which supports the hypothesis on the cyclicality of real wages. This study has policy implications that labor market conditions matter for the economic well-being of TANF leavers and the labor demand policies are needed for the economic security of TANF leavers after the exit.
