Objectives : The purpose of this study is to investigate the possibility of using herbal medicine for the management of psoriasis focusing on lipid metabolism. Methods : We reviewed studies about pathophysiology, and medical treatment of psoriasis, the relationship between psoriasis and metabolic syndrome and lipid metabolism, and herbal medicine on Pubmed and Google scholar. Results : Psoriasis is a chronic multi-organ inflammatory disease not limited to skin, and steroids, immuno-suppressants, and biological agents are used. It is known that psoriasis and metabolic syndrome act as mutual risk factors, and lipid metabolism are involved in psoriasis. The effects of various single herbal preparations and complex herbal extract, decoction on improving lipid metabolism have been consistently reported, and there was an improvement of psoriatic skin lesions and improvement of blood lipid levels through herbal medicine. Conclusions : Herbal medicine research in psoriasis has focused on the anti-inflammatory effect and the suppression effect of certain immune mediators. However, considering that psoriasis is affected by lipid metabolism and side effects of Western medicines, the use of herbal medicines for the purpose of controlling lipid metabolism in psoriasis is useful in aspects of reducing side effects of concurrent Western medicine, improving the severity of psoriasis, and managing metabolic risk factors.

Purpose - This study investigates the effects of earnings management, related party transactions between chaebol affiliates on earnings management and ESG score on their profitability using return on assets (ROA). Design/Methodology/Approach - We use data including ESG (Environmental, Social, and Corporate Governance) score of the Korea Corporate Governance Service(KCGS), and financial data of 10,145 firm-year observations from the Total Solution 2000 (TS 2000) and Korea Companies-Information Service (KOKOInfo), and apply the finite lagged models to investigate the long-term effects of related party transactions between chaebol affiliates of earnings management on ESG scores and corporate performance. Furthermore, to take into consideration the simultaneous mutual effects on each other of main variables, we introduce finite distributed lags of five years. Findings - First, ESG-rated firms have a higher total asset return than non-ESG-rated firms. Second, chaebol firms have a higher profitability than non-chaebol firms. Third, profit management of related party transactions between affiliates within a chaebol has a positive effect on the short-term profitability and a negative effect on the long-term profitability. Fourth, chaebol ESG firms have a lower impact on profitability due to rating up (down) than non-chaebol ESG firms. Research Implications or Originality - Based on the above results, it can be concluded that firms used related party transactions for earnings management, the effects of related party transactions change over time, and chaebol firms manipulate earnings through related party transactions and ESG scores.

This paper introduces the effect of grease on the degradation characteristics of bearings used as key components of packaging equipment and automation systems. Bearings parts are installed to fix and support the rotating body of the system, and performance degradation of the bearings has a great effect on the life of the system too. When bearings are used in various devices and systems, the grease is applied to reduce friction and improve fatigue life. Determining the type of lubricant (grease) is important because it has a great influence on the operating environment and lifespan and ensures long lifespan of systems and facilities. However, studies that simultaneously compared and analyzed the change in mechanical degradation characteristics and the comparison of chemical degradation characteristics according to grease types under actual operating conditions are insufficient. In this paper, three types of small harmonic drive, high-load reducer, and low-load reducer grease used in power transmission joint modules are experimentally selected and finally injected into ball bearings with a load (19,500N) to improve bearing durability. Degradation characteristics were tested by attaching to test equipment. At this time, after the durability test under the same load conditions, the mechanical degradation characteristics, that is temperature, vibration according to the three greases types. In addition, the chemical degradation characteristics of the corresponding grease was compared to present the results of mutual correlation analysis.

This study aims to reveal the factors that influence purchase intention according to Korean-Chinese consumers in e-commerce. In addition, the study has comprehensively confirmed the influence between each factor in the e-commerce environment by integrating and analyzing the characteristic factors of online information sources and platforms in one structural equation. Finally, the study confirmed that there is a significant difference in the influence relationship between Korean and Chinese consumers. Through this, the study will contribute to content production in the e-commerce market according to the target market and the expansion of the mutual entry of Korea and China. Design/methodology - This study aims to confirm the mediating effect of the details of the online information source characteristics and platform characteristics when the perceived quality affects purchase intention. It is confirmed that the factors affecting Korean and Chinese consumers differ. Findings - It was confirmed that differences exist according to the group of Korean or Chinese consumers for the entire research model. In the case of Korean consumers, the mediating factors when perceived quality affects purchase intention are expertise, reliability, entertainment, informativity, and convenience; in the case of Chinese consumers, the factors are expertise and informativity. Originality/value - This study proved that Korean and Chinese consumers cannot be regarded as having the same characteristics, and therefore, strategies aimed at each e-commerce market should be differentiated. In addition, although previous studies on online information sources and platform characteristics were not integrated, this study confirmed a significant influence relationship among the factors that could affect purchase intention in the actual e-commerce environment.

Purpose - Recently, as Korean culture and economy develops, Seoul has become a world-famed city. In Seoul, many special grade hotels have been constructed in order to accommodate many tourists from China, Japan and many other Asian countries. And the hotels entered into competition among themselves. Thus many changes are accelerated due to their mutual competition and manpower problems. In this situation, the role of higher officers above all is thought to be very important in order to enhance the management result and to make preparations for the kernel ability of the organization. Research design, data and methodology - This study was intended to verify how the leadership of the higher officers based on trust affects the job satisfaction of employees of the organization. In order to achieve the purpose of this study, some study models and hypotheses have been established through theoretical examinations. The subjects of this study were centered on the constituents of C-Hotel, M-Hotel, and D-Hotel. 200 questionaries were distributed and 190 questionaries were collected and thus the collection ratio was 91 percent. 8 questionaries which were regarded to be insincere or hard to analyzed were excluded. Finally, 182 questionaries were used for analyzing the factors and trust. For the purpose of the verification of hypotheses, structural equation was used. In order to verify the mediating effect of trust between the relationship of emotional leadership and job satisfaction, 'Three-step Mediated Regression Analysis by Baron & Kenny(1986) was utilized. The four hypotheses for this study are as follows: First, emotional leadership will have a meaningful influence on trust in the affirmative. Second, trust will have a meaningful influence on job satisfaction in the affirmative. Third, trust will play a mediating role in the relationship of emotional leadership and job satisfaction. Result - First, the emotional leadership and trust was found to effect a positive effect. Second, the trust and job satisfaction was found on a positive effect on job satisfaction. Third, the emotional leadership and job satisfaction was found to positive effect on job satisfaction. Fourth, the trust in the relationship between emotional leadership and job satisfaction was found that the partial mediating effect. Especially, in the case of the business of hospitality, human services as well as material resources become its keynote, and we can safely say that the degree of dependence toward human resources is very high. Accordingly, the leaders should display their leadership on the basis of abundant emotional and intellectual faculties so that they can grasp, understand and admit the diverse views of value and emotion of the organization constituents and that they can form emotional leadership. On the basis of the analysis results of the verification of hypotheses, some suggestions and uppermost limit of this study have been presented for further study.
