  • Since military weapon accidents or breakdowns are directly linked to enormous damage, it is important to analyze the causes of weapons system accidents. Recently, in the defense sector, there have been cases in which budget has been saved through analysis of the causes of frequent breakdowns and improvement activities that have occurred in the process of operating weapon systems since 2015. But due to the nature of the defense sector, it is not easy to collect data and studies on weapons system accidents have been insufficient so far. Therefore, this study aims to investigate the causes and types of military weapon accidents by collecting military weapon accident data for military weapon systems and analyzing trends by weapon system classification through the analysis process. It analyzes statistically and visually through social network analysis, NodeXL. It is expected that this study will help improve the stability of the weapon system by reducing the number of military weapon accidents and failures.

  • Recently, one of the core keywords in information technology (IT) as well as areas such as business management is big data. Big data is a term that includes technology, personnel, and organization required to gather/manage/analyze collection of data sets so large and complex that it becomes difficult to manage and analyze using traditional tools. The military has been accumulating data for a long period due to the organization's characteristic in placing emphasis on reporting and records. Considering such characteristic of the military, this study verifies the possibility of improving the performance of the military organization through use of big data and furthermore, create scientific development of operation, strategy, and support environment. For this purpose, the study organizes general status and case studies related to big data, traces back examples of data utilization by Korean's national defense sector through US military data collection and case studies, and proposes the possibility of using and applying big data in the national defense sector.

  • Several US veterans stationed in Korea have told the press that around 250 fifty-five gallon drums of herbicides, including Agent Orange, were buried at Camp Carroll in 1978. Joint Korean-US Agent Orange investigation and environmental and health studies were started in July 2011. Korean soldiers and military personnel who served in Vietnam during 1964-1973 or near the demilitarized zone in Korea during 1967-1970 were exposed to dioxincontaminated Agent Orange. The joint Korean-US Agent Orange investigation team found that herbicides, pesticides, solvents and other chemicals -not Agent Orange- were buried at Camp Carroll. However, there remains the possibility that Agent Orange was stored and buried at Camp Carroll or other military camps in Korea. Adverse health effects have not been clearly explained despite a number of health studies among veterans in Korea with potential Agent Orange exposure. Although the Korean government has been compensating veterans and military personnel with 18 presumptive-service-connected-diseases and their offspring with three diseases, there are many veterans, military personnel and civilians who require the government°Øs support. The environmental study on contaminated sites and health studies among veterans and civilians were initiated three or four decades after possible Agent Orange contamination and exposure. Several toxic chemicals, including dioxin-contaminated Agent Orange, could remain in the environment and could have hazardous effects on the health of exposed people for more than several decades. Further environmental investigations and health studies are needed to ensure public safety and health, and government support should be guaranteed for people potentially exposed to these toxic chemicals.

  • Handling of the large quantity of oil, generation of heavy metals at the military blasting range and outworn facilities could cause the environmental accidents. Pollution levels of the former five U.S military bases located in Uijeongbu, Gyeonggi-do were measured. Soil contamination by TPH (Total Petroleum Hydrocarbons), BTEX (Benzene, Toluene, Ethylbenzene, Xylene), and heavy metals and groundwater contamination were detected. In order to purify contaminated soil, a variety of technologies including soil vapor extraction, slurping, landfarming and soil washing were applied. Contaminated soils of five target bases were purified and the results were suitable for the legal standards.

  • Although self-propelled artilleries are mobile equipment, they need their own covered-positions for survival against preemptive strikes. The most important military requirement is enough protective capacity against blast pressure caused by explosion. This paper aims to assess the protective capacity of the newly-placed concrete box-type artillery positions using accurate structural geometric models as well as soil-structure interaction analysis. The commercial program is used to model the structural geometry of the positions. In order to describe the correct wave propagation in the backfill along with soil-structure interaction, used parameters in shock equation of state are selected based on the related studies as well as theories and then their final results are verified with the ones calculated with empirical equations in the US Unified Facility Criteria. In sum, it could be concluded that the protective capacity of the newly-built positions satisfies the protective structural requirement.

  • Interest about the effect of military service is increasing because of the renewal of military service incentive system in Korea. In the background, men has been experienced which suffer monetary and non-monetary damages through the compulsory military service in Korea. However there are few studies that analyze the labor market effect of military service. This study takes advantage of male worker's data of 10th KLIPS(Korea Labor & Income Panel Survey) in 2007 and analyze the wage effect of military service. According to empirical result using Mincerian earnings function, the positive effect of military service appeared. These result shows men who finished military duty have an monetary advantage in Korean labor market unlike general perceptions on military service.

  • To carry out multi-domain operations included in the U.S. Department of Defense's national security strategy in 2018, timely data sharing between C4I systems is critical. Several studies of the Korean military have also raised the problems of interface and standardization between C4I systems, and it is necessary to establish a new plan to solve this problem. In this study, a solution to the problem was derived through case analysis that the U.S. Department of Defense has been pursuing for about 20 years to implement the data strategy after establishing the data strategy in 2003. and by establishing a data strategy suitable for the ROK military C4I system operating environment, developing a data model, selecting a standard for data sharing, and proposing a shared data development procedure, we intend to improve the data sharing capability between ROK military C4I systems.

  • The purpose of this study was to examine the satisfaction level of military personnels dispatched to Iraq with foodservices in a bid to help establish an efficient overseas military foodservice system. A total of 300 soldiers who served in an army division dispatched to Iraq was surveyed for this study. Regarding connections between the type of management and satisfaction level with foodservices, the contracted cafeterias were more satisfactory in terms of service than the military selfoperated ones, which indicated that it’s urgently needed to improve the service of the military-run cafeterias. The present work force of the Ministry of Defence makes it hard to provide military personnels with specialized foodservices. The military foodservice should provide meals to soldiers with quality. More branded concepts should be improved in the view of cost and effect. Or it’s advisable to take advantage of private resources as part of efforts for civil-military collaboration.

  • The esophageal squamous cell carcinoma (ESCC) is an aggressive tumor with a poor prognosis. Understanding molecular changes in ESCC should improve identification of risk factors with different molecular subtypes and provide potential targets for early detection and therapy. Our study aimed to obtain a molecular signature of ESCC through the regulation network based on differentially expressed genes (DEGs). We used the GSE23400 series to identify potential genes related to ESCC. Based on bioinformatics we constructed a regulation network. From the results, we could establish that many transcription factors and pathways closely related with ESCC were linked by our method. STAT1 also arose as a hub node in our transcriptome network, along with some transcription factors like CCNB1, TAP1, RARG and IFITM1 proven to be related with ESCC by previous studies. In conclusion, our regulation network provided information on important genes which might be useful in investigating the complex interacting mechanisms underlying the disease.
