Objective: The goal of this study was to determine the anti-asthma mechanism of SF on TNF-${\alpha}$ induced activation on A549 (human type II-like epithelial) cells. Using oligonucleotide microarray, we sought to establish the molecular mechanism of the protective effects of SF on A549 cells. Material & Methods : Cells were cultured in three different conditions: 1) negative control group was cultured in normal condition of DMEM, 2) positive control group was activated with TNF-${\alpha}$, IL-4. and IL-1${\beta}$, and 3) SF treated group was previously treated with 0.1${\mu}g/ml$ SF after TNF-${\alpha}$, IL-4. and IL-1 activation. Cells of positive control and SF treated groups were cultured for 30 min, 1hr, 3hr and 6hr. Results : The comparative analysis of the gene expression profile revealed that proinflammatory cytokines such as IL1F8, IL1F9, IL1R1. IL1RN, IL1RAPL1, IL8, TNFRSF4, TNFSF10c, TNFSF13, TRAF5, and TRAF7 and inflammation-related genes including MMP2, MMP11, MMP14, MMP15, MMP16, MMP19, MMP25, and MMP27 were down regulated with SF treatment. Cell adhesion molecule genes such as ITGB1, ITGBL1, selectin P ligand, selectin E, ICAM2, ICAM3, VCAM1, PECAM, FCER1G and MMP28 genes were also down-regulated in SF treated A549 cells. Conclusion : These results suggest that the anti-asthmatic effects of SF could be mediated by regulating specific genes related with cell adhesion, proinflammatory cytokine and inflammation-related genes in A549 cells.

Since airline safety depends significantly on the role of pilot, the importance of airlines' training qualified pilots and investing in the training program grows. This study aims to analyze the determinants of the commercial airline pilot competencies during the transition course. To this purpose, one-year training evaluation results of 215 new airline pilots in the JET transition course of Company K in 2019 are studied with correlation coefficient analysis, factor analysis, ANOVA, and regression analysis. Undergraduate major and Uljin-trained pilots show higher final-stage scores in PROC, AUTO, and CRM. Due to Uljin-trained pilots' higher first-stage scores, their score increase during the course is limited. Uljin-trained pilots' MANUAL scores in the final stage are lower than those of undergraduate major and overseas-trained pilots. Influence of trained location is found greater than English competency, undergraduate GPA, and ground school scores on commercial airline pilot competency evaluation scores during the program. The results will be useful in establishing scenario-based training focusing on different background to apply competency-based training and assessment.

기업의 웹사이트는 기업의 환경 변화를 주도하는 관문으로서의 역할을 하고 있다. 그러나 현재 기업의 웹사이트 평가지표에 대한 연구는 진행되지 않고 연구의 대부분이 웹사이트의 외형적인 측면들을 평가하고 있다. 특히 e-Biz 측면에서 전자상거래 주체인 B2B(Business to Business) 웹사이트에 대한 연구는 거의 이루어 지지 않고 있어, 기업 관점의 웹사이트 평가와 B2B 웹사이트에 대한 평가지표 연구가 필요하다. 본 연구는 평가지표 KPI(Key Performance Indicator)를 도출하고, AHP(Analytic Hierarchy Process) 기법으로 웹사이트 평가 연구를 통하여 평가지표를 추출한 후 B2B에 적용함으로써 각 지표들의 중요도 및 가중치의 차이를 살펴본다. 이를 통해 기업과 기업간에 전자상거래 규모의 확대에 따른 의사결정과 B2B 웹사이트를 보다 쉽게 설계 할 수 있는 명확한 기준을 제시하였다.

As the global air traffic volume has shown a rapid increase, doubling every 15 years since 1977, domestic and international air traffic control services and air navigation safety facility operation management system and status review It is necessary to present the feasibility of establishing an air traffic control agency with integrated functions and establish an operating system for an independent dedicated agency to provide advanced air traffic control services in preparation for the future air transport environment. In particular, in 2021, the National ATM Reformation and Enhancement (NARAE) a customized comprehensive plan for operations, facilities, and systems to handle air traffic safely and efficiently by actively reflecting changes in the navigation environment such as international policies and standards as this is established, the role of the air traffic control agency becomes more important, and an improved action plan for the control and navigation operating system must be promoted.

The WTO Thailand-Philippines Cigarettes Dispute, which will be central to this study, is an example of in-depth discussion over each clause of the WTO Customs Valuation Agreement, as well as through the WTO Dispute Settlement Procedure, the Panel and Appeals Organization and the Implementation Conformity Procedure under Section 21.5 of the DSU. In addition, the need and implications of the research are significant in that the WTO panel judgment on the detailed provisions of the CVA on the transfer price, which have not been dealt with much, and the issue of how the CVA can be applied in the possible criminal prosecution of customs criminals within member countries, were discussed in depth. Therefore, this study drew up the issues that were mainly addressed in Thailand-Philippines Cigarettes Dispute Case and looked up the analysis and evaluation and implications of the issues. With the advanced transfer pricing in the multinational-led trade environment, tariff assessments on it will become more important, and not only tariff assessments, but also the manipulation of transfer prices could lead to cutoms crimes that greatly exceed the level of tax avoidance. In the future, it is time for Member States to conduct further research on practical discussions and methods that actively consider that the assessment of tariffs on transfer prices should not only be considered from a tax perspective, but that crimes originating from transfer prices may be substantially within the scope of the Convention on duty Assessment.

Purpose - The purpose of this study is to examine the effect of performance-related pay on gender labor productivity differences theoretically and empirically. Design/methodology/approach - This study analyzes the Principal-Agent model in which a firm employes many male and female workers under moral hazard, and uses large survey data from Survey of Business Activities of MDIS (MicroData Integrated Service) in Korea. The fixed-effect model is employed in order to analyze the data. Findings - The theoretical result is that, after performance-related pay is offered to workers, the effect of performance-related pay on gender productivity is determined by whether the female ratio within firm affects firm’s performance(such as revenue and profit) per capita. The empirical result is that, before performance-related pay is provided for all workers, the firm’s female ratio does not affect firm’s revenue and profit per capita at all, but after it is offered, the female ratio positively affects firm’s performance per capita. Research implications or Originality - Fixed pay does not bring about the difference between male and female productivity, but performance-related pay affects female productivity more positively than male productivity in Korean firms. It means that female workers are more sensitive to incentives than men in Korea.
