In the Republic From the national interest in the recent hiring scandals in the public institutions such as the Financial Supervisory Service, Gangwon Land, and so on, people were outraged by the fact that the competition opportunities were not secured although they should be equally secured to compete with anyone with their capabilities in the fair process. Hence, the government made the public institutions blind hiring to be mandatory, which eliminated writing the academic background, GPA, and English score in the application form and selected the new employees only with job competencies in the public institutions in 2017. In 2018, the prosecution did their best for the investigation on hiring scandal with the strong will to cut the scandal upon announcement of 5-year anti-corruption master plan. Amid this controversy, this study tries to suggest the further direction in the hiring military human resources upon introduction of blind hiring system, reviewing the needs to introduce blind hiring system in the military, the governmental guideline according to the mandatory blind hiring in the public institutions, and the application status of modified blind hiring in the military.

When a traumatic subject experiences extreme stress, various psychiatric problems, including PTSD, can occur if they do not respond appropriately. In addition, non-war soldiers who experience life-threatening events while serving in the military may experience severe and chronic PTSD symptoms. However, there are still insufficient domestic studies on what traumatic events soldiers are exposed to and how much PTSD symptoms they experience. Therefore, this study provides a method that can be used as basic data for PTSD and psychological support of military service personnel by identifying trends in domestic research. Furthermore, it studies PTSD not only of soldiers but also of 'civilians' who have experienced combat, and provides symptomatic treatment and relief programs to civilians according to the difference in PTSD between general trauma and war trauma. It is expected that these studies will increase military confidence and enable the military to play a leading role in war trauma PTSD research and prevention, treatment and mitigation.

In recent years, the ROK military is promoting Defense Innovation 4.0 with the goal of fostering strong military based on science and technology equipped with artificial intelligence(AI) to prepare for the upcoming population cliff. In particular, at the present time of increased threats of North Korea, the South Korean military is seeking to deal with a decrease in military service resources through the introduction of a Scientific Guard System using advanced technology. TICN which is a core basic communication system to ensure the integrated combat capability of the ROK military is, however, limited to use as a based network for the emerging Scientific Guard System due to the narrow transmission bandwidth with widely spread poor reception area. To deal with this problem, this paper proposes TVWS-based Scientific Guard Systems with TVWS-based wireless network construction technology that has been available for free in Korea since 2017. The TVWS-based Scientific Guard System proposed in this paper, when compared to the existing wired network-based Scientific Guard Systems, has various advantages in terms of minimizing operational gaps, reducing construction costs, and flexibility in installation and operation.

For many years, there have been many researches and guidelines to improve the employment rate of discharged soldiers. However, there have not been enough effective analysis conducted about the outplacement service and improvement guidelines. That is the reason why the satisfaction level of governmental supporting programs for the discharged soldiers stays at low level. Therefore, a methodical approach is needed for the discharged soldiers who have dedicated their services for many years for the sake of the country's security. For this reason, tools which can support build an effective outplacement service for the discharged soldiers are required. In this study, psychological, structural and environmental aspect of discharged soldiers were surveyed at the cognitive level based on the soldiers waiting for the discharge from military service. As a result, it became clear that psychological advice or support and job training for the discharged soldiers who executed long-term service are urgent. In addition, an efficient system can control and maintain the system mentioned above.

The term "spoofing" refers to the transmission of counterfeit signals to provide undetectable falsification of GPS service. A spoofing can be accomplished using information from open literature which defines the signal format and the data structure. Spoofing is intended either to produce erroneous navigation solutions or saturate the processor of the victim receiver. The GPS receiver has no way to get rid of the effect of a spoofing because GPS receivers for civil service do not have an anti-spoofing scheme. This paper analyzes the spoofing characteristics, spoofing methods and environment conditions. And the spoofing effects on GPS receiver are analyzed in detail using the designed software-based spoofer and the Nordnav receiver.

In this paper, we introduce a roots method that uses the roots inside the unit circle of the associated characteristics equation to evaluate the steady-state system-length distribution at three epochs (pre-arrival, arbitrary, and post-departure) and sojourn-time distribution in GI/PH/1 queueing model. It is very important for an air base to inspect airplane oil because low-quality oil leads to drop or breakdown of an airplane. Since airplane oil inspection is composed of several inspection steps, it sometimes causes train congestion and delay of inventory replenishments. We analyzed interarrival time and inspection (service) time of oil supply from the actual data which is given from one of the ROKAF's (Republic of Korea Air Force) bases. We found that interarrival time of oil follows a normal distribution with a small deviation, and the service time follows phase-type distribution, which was first introduced by Neuts to deal with the shortfalls of exponential distributions. Finally, we applied the GI/PH/1 queueing model to the oil train congestion problem and analyzed the distributions of the number of customers (oil trains) in the queue and their mean sojourn-time using the roots method suggested by Chaudhry for the model GI/C-MSP/1.

We conducted a survey related to study methods to identify the factors that have an influence on the academic achievement of university students and analyzed the results of this survey for correlation with students' GPA, which represents academic achievement. Test preparation and effective study habits were found to be the most important factors in overall student achievement. However, when divided by grade, maintaining health and satisfaction with school life are the most important factors for sophomores. Rather, in grades 3 and 4, time spent maintaining health is negatively reflected in improving academic achievement. Divided into gender, male students review or daily academic effort is an important factor in academic achievement, but in the case of female students, there is no difference in relative academic achievement because the amount of review and academic effort are small. For students who have experienced military service, review and test preparation are important to academic achievement, but for students who have not experienced military service, review has no effect on relative academic achievement.

Due to the expansion of data and technical progress in the military industry, it is important to extract meaningful information for assuring quality and making policies. The analysis of trends and decision making based on big data is helpful for increasing productivity in business and finding new business opportunities. We propose an application to collect reliable quality information for munitions and build a big data platform for using the accumulated information and numerical data. We verified the proposed platform using the Test Report Information Service (TRIS) system and suggest a method that utilizes unstructured and semi-structured data accumulated by TRIS. Thus, we expect that the proposed platform will help in building infrastructure for military data, making efficient strategies, and analyzing trends for assuring munitions quality.
