In this study, we investigated whether the degree of anxiety, depression, stress, and ego resilience in the COVID-19 epidemic situation could affect the quality of life of college students and analyzed the correlation between them. In addition, the causal relationship and mediating effect on ego resilience, stress and quality of life were analyzed and necessary countermeasures were proposed. As a result of analyzing the correlation between each variable, it was found that anxiety, depression, stress, quality of life, and self-resilience all had significant correlations. In particular, stress was found to play a complete mediating role in the effect of ego resilience on quality of life. It is expected that this study will be used as a basis for research on the effect of stress and self-resilience on the improvement of quality of life in the Corona situation.

One of the issues of the automotive industry today is autonomous driving vehicles. In order to achieve level 3 or higher as defined by SAE International, harmonization of autonomous driving technology and connected technology is essential. Current vehicles have new features such as autonomous driving, which not only increases the number of electrical components, but also the amount and complexity of software. As a result, the attack surface, which is the access point of attack, is widening, and software security vulnerabilities are also increasing. However, the reality is that the essential security requirements for vehicles are not defined. In this paper, based on real attacks and vulnerability cases and trends, we identify the assets in the in-vehicle network and derive the threats. We also defined the security requirements and derived essential security requirements that should be applied at least to the safety of the vehicle occupant through risk analysis.

The purpose of the study is to examine the relationships of parents' satisfaction towards their children's school education and the demographic variables associated with decision-making on post high school academic completion of parents of the students with disabilities. The Korean Education Longitudinal Study data, which contained the responses of 162 parents of high school students with mild disabilities who enrolled in regular high schools, was used for the study. For data analysis, descriptive statistics, ordinal logistic regression analysis, and chi-square test were used. As a result, provision of college entrance related information/consultation, improvement of academic performance level, collaboration/ communication between the teachers and parents, and overall school education were significantly related to parents' decision-making on their children's post high school academic completion. Also, mothers' educational level showed significant difference in parents' decision-making on their children's post high school academic completion.

Fonts are digitized into a file and recognized as a intellectual property by the revision of the design protection act in 2005. Fonts are passed on to the users and are developed into design products. In this study, we have developed a model of font usage system as a design product based on Ahn Se Yoon's brand value system model. Based on the usage system model of the typeface, the lifecycle as a design product of the typeface was defined and analyzed as four different phases (introduction, growth, maturity, and decline.) In this study, To investigate the lifecycle of fonts, we selected the Gulim-chae which is most widely used as digital font files in Korea and are now in decline phase. Through this study, We hope that it will be useful for developing fonts, licensing system, and establishing brand strategies.

Green water impact may sometimes cause some structure damages on ship's bow deck. Prediction of proper design pressure against the green water impact is an essential task to prevent the possible damages on bow deck. This paper presents a computational method of the bow deck's design pressure against the green water impact. Large heave and pitch motions of ship are calculated by the time domain nonlinear strip method. Green water flow and pressure on bow deck are simulated by the predictor-corrector second kind upstream finite difference method. This green water simulation method is based on the shallow water wave equations expanded for moving bottom conditions. For various kind of ships such as container ship, VLCC, oil tanker and bulk carrier, the green water design pressures on bow deck are computed and discussed. Also, the obtained results of design pressure on bow deck are compared with those of the classification society rules and discussed.

Maritime back-up navigation system in port approach requires a horizontal accuracy of 10 meters in IALA (International Association of Lighthouse Authorities) recommendations. eLoran which is a best back-up navigation system that satisfies accuracy requirement has poor navigation performance depending signal environments. Especially, noise caused by multipath and electronic devices around eLoran antenna affects navigation performance. In this paper, Ship based Navigation Back-up system using UAV on Interference is designed to satisfy horizontal accuracy requirement. To improve the eLoran signal environment, UAVs are equipped with camera, IMU sensor and eLoran antenna and receivers. This proposed system is designed to receive eLoran signal through UAV-based receiver and control UAV's position and attitude within Landmark around area. The ship-based positioning using eLoran signal, vision and attitude information received from UAV satisfy resilient and robust navigation requirements.

The Film Development Fund was established in 2007 to improve the quality of film arts and promote the Korean film and video industry. As a key resource operated by the Korean Film Council, the film development fund provides various projects including support for the promotion of Korean film creation and production, funding in video-specialized investment associations, export and international exchanges of Korean films, and production of small-scale or short films. This study aims to propose ways to reinvent the film development fund, which is in danger of being depleted. Based on such purpose this study examined the status and problems of the current film development fund and reviewed previous literatures and related discussions. Furthermore, the policies of similar overseas organizations for film promotion including French National Film/Video Center (Centre National du Cinema et de l'image $anim{\acute{e}}e$, CNC) and the British Film Institute (BFI) were reviewed to draw a multi-faceted way to replenish the source of revenue for Korean film development fund.
