The purpose of this study is to analyse the impact of macroeconomic and non-macroeconomic forces on the management performance of the air transport firms and offer the useful information to the managers. To conduct the regression analysis, eight macroeconomic and non-macroeconomic variables were selected individually as an independent variable. Macroeconomic variables were the return of corporate bond, West Texas Intermediate, the unemployment rate, the money supply, the trade balance, the won to USD exchange rate, the consumer price index and the index of industrial production. And non-macroeconomic variables were Taiwan earthquake, the Asian economic crisis, the 911 terrorist attacks in the US, the Iraq war, Beijing Olympic, the outbreak of a swine flu epidemic, the 1st presidential election and the 2nd presidential election. And ROA was selected as a dependent variable. As the result of analysis, it was found that the changing rates of won to USD exchange rate and consumer price index affected the changing rate of ROA significantly. And also as the result of analysing the impact of two significant macroeconomic variables and eight non-macroeconomic variables on the changing rate of ROA, it was found that the Asian economic crisis and the outbreak of a swine flu epidemic had a negative impact on it. Therefore managers should take note of a change in macroeconomic and non-macroeconomic variables carefully to improve the management performance.

The goal of this study was to investigate the influence of exercise training with or without blood flow restriction (BFR) on physical performance and balance in elderly females. Participants (N = 43) were randomly divided into combined exercise with BFR group (n = 14, EX-BFR), only combine exercise group (n =14, EX) or a non-exercise control group (n = 15, CON). Both EX-BFR and EX groups had completed exercise training for 12 weeks. During the training period, the CON group maintained their normal lives. After baseline tests, two-way repeated measures ANOVA with contrast testing was conducted using SPSS 22.0. Study results found that physical performance and balance in both EX-BFR and EX groups were significantly improved, and fall index in both EX-BFR and EX groups were significantly decreased. There were no changes in the CON group. In addition, the % change and effect size of all variables in the EX-BFR group were larger than the EX group. So, the results showed that the EX-BFR group had performed more intense exercise caused by restricted blood flow during the training period compared to the EX group. Thus, exercise with BFR training may additionally influence physical performance and balance in elderly females.

Breaking away from the blind faith of internal military security network, current military security demands strengthening measure on the H/W, controlling measure against information communications within the military, strengthening measure on the linkage point of the military and universal internal networks, legal supplementation, sucurity management ofn the military facilities from outsourcing services supporting the military. By analyzing the danger of military organizations hacking and real hacking cases, policy establishment for strengthening the security on military network hacking, legal supplementation and controlling measure for the outsourcing services are the pragmatic counter measures against military security hacking considering the peculiarities of military rather than the application of physical containment linked with information communications technology on the H/W safety measures.

MyData is an approach of personal data management, which grants data subjects the right to decide how to use and where to provide their data. With the explicit consent of the subjects, service providers can collect scattered data from data sources and offer personalized services based on the collected data. In existing service models, personal data saved in data storage can be shared with data processors of service providers or third parties. However, once personal data are transferred to third-party processors, it is difficult for data subjects to trace and control their personal data. Therefore, in this paper, we propose a cloud model where both data storage and processor are located within a single cloud, ensuring that data do not leave the cloud.

The purposes of this thesis are to grasp the aspect of injuries by violence which is the recent social issue, analyze the relationship with socioeconomic factors and provide it as the basic material of policy development and prevention. With the specimen in-depth investigation materials of injured patients of emergency room which is injuries examination system based on medical institution, this thesis compared injuries by violence with aspect of other injuries and conducted logistic regression analysis after controlling gender, age, educational level and occupation mutually. Women showed more danger to be exposed to injuries by violence than men. The less the age was, the more danger by violence was. The more academic background was, the less rate to be exposed to violence was. For occupations, there were dangerous in order of service workers, shop and market sales workers, unemployed, elementary occupations. In conclusion, Some differences of socioeconomic factors made an effect on the danger of injuries by violence victim.

In smart grid, enhancement of efficiency and interoperability of electric power system is achieved through the connection with outer network, and this induces that power grid system is threatened increasingly, becomes the main target of cyber terrorism, and is sincerely required to design the secure power system. Although SSDLC(Secure System Development Life Cycle) is used for risk management from the design phase, traditional development life cycle is somewhat limited for satisfaction of information security indicator of power control system. Despite that power control system should reflect control entities of information security considering its own characteristics, validation elements are insufficient to apply into real tasks based on existing compliance. To make design of diagnostic model and assessment process for power control system possible and to give a direction for information security and present related indicator, we propose the new risk management framework of power control system which is applied operational security controls and standard architecture presented by IEC 62351 TC 57 with enterprise risk management framework.

This study aimed to identify the risk factors for cardiovascular disease (CVD) among age groups using the Framingham risk score (FRS). The research design used was a cross sectional descriptive study using the Sixth Korean National Health and Nutrition Examination Survey from 2013-2015. Data from 5211 men, between the ages of 30-74 was analyzed. After adjusting for age, the result of logistic regression analysis showed that obesity (OR=2.51 95% CI=2.05-3.07), physical inactivity (OR=1.71, 95% CI=1.39-2.10), heavy alcohol drinking (OR=1.33, 95% CI=1.09-1.62), and dietary fiber intake (OR=0.99, 95% CI=0.98-0.99) were presented as predictors of CVD. Obesity was considered to be a particularly important predictor of CVD for young and middle-aged men. This result will be used for developing intervention relating to lifestyle modification for young and middle-aged men.

With rapid growth in the technologies and demand of Remotely Piloted Aircraft Systems (RPASs), integration of such systems into the existing airspace system is becoming an issue in many countries. RPAS have different flight performances, communication characteristics, separation assurance mechanisms, and human machine interfaces from manned aircraft. To establish rules and regulations for RPAS integration, it is important to understand the impacts of RPASs on the airspace system. A simulation system that integrates manned aircraft, air traffic control, and RPASs is developed in Inha University to investigate these impacts through Human-in-The-Loop (HiTL) simulations. Three conflict resolution scenarios between a manned aircraft and a Remotely Piloted Aircraft (RPA) were constructed and tested. Human factors such as the response times of pilots and controllers were measured and analyzed as well as the risk of each maneuver.
