Purpose: The purpose of this study was to analyze the career barriers of students studying dental technology in D-College. Methods: This study targeted 490 college students studying Dental Technology in D-College. The survey about career barriers on this study consisted of 45 questions and was scored with 5-points per question. The corrected data was analyzed by SAS V8 for Windows. Results: The difference analysis of career barriers shows that differences exist depending on gender(p<.01) and serving military service(p<.05). Especially, female students(2.69) and male students(2.65) who didn't serve the military are more susceptible to career barriers. In the sub factors of career barriers, differences exist depending on and in order of gender, serving military service, experience studying one more year to enter the college, day and night, the affiliation of highschool graduated from, and hometown. The correlation between the sub factors of career barriers and perception of career barriers manifested 'Lack of self assurance'(0.84), 'Sense of physical inferiority'(0.76), 'Relationship with other important people'(0.73) and 'Lack of information on occupation' in order. Conclusion: In the factors affecting non-decision on the career, 'Lack of self assurance'(=0.2465) is the highest in terms of influence, followed by 'Difficulty in interpersonal relations’(=0.1801) and 'Lack of information on occupation' (=0.1391).

Korean military is propelling the M&S on new warfare concept, such as NCW(Network Centric Warfare) which is the aspect of future war. IPv6 is the essential element of next generation defense network which is supporting the future battlefield. There have been many studies on allocating the IPv6 address for next generation defense network. However, they assigned the address by level on the basis of the military organization or assigned it from the service network, so it had the defect, the big size routing table. This study reviews the topology of next generation defense network and adjusts the position of service network ID on the basis of the network topology. Finally, it improved the efficiency of route aggregation and minimized the routing table size in comparison with the previous studies and it was proved by OPNET simulator.

South Korea is in a dangerous situation where a war between the two Koreas could be triggered at any time based on the MDL (Military Demarcation Line) between the two Koreas due to the inter-Korean standoff over the armistice. Also, unlike the borders of other countries, the border between the two Koreas is the front-line area where people can feel the threat of life that could be triggered by war. Soldiers who work in special areas such as the contact area are not easily accessible due to local conditions, and are less likely to go out, stay out, stay out, or visit, and the working environment is overloaded with vast forests and silence at night, and feel anxious, lonely and insecure because they don't know when any situation will occur near the enemy. Therefore, a great deal of help will be needed to pay attention to soldiers who give up their lives here and perform their national defense duties, and to finish their barracks life safely and faithfully, and support for psychological adaptation of service members in the border areas.

In the 4th industry, drones are being used while having a close relationship with our lives. The development and use of various drones suggests a new paradigm for the domestic industry in the future, and is expected to become more advanced and scientific. Meanwhile, in the field of defense, efforts are being made in various ways to overcome the social phenomenon of reduced service resources. It is concentrating its efforts on strengthening the national defense power by preparing an exit strategy to supplement the shortage of service resources and to maintain and improve combat power, and by combining various science and technology related to the 4th industry. The military is planning to reinforce its combat power in connection with future industries to effectively respond and perform missions in preparation for the future combat aspects that have been researched and planned, and is planning an unmanned combat system for the science and technology army by investing a separate budget. Therefore, we systematically introduce and utilize drones, which are the core of the unmanned combat system, to create more active combat power and seek countermeasures for the battle vacuum, It is expected to provide a new paradigm for the battlefield when using advanced technology developed in the private sector and grafting it to the military sector.

In Korea, the birth rate is rapidly decreasing in the 21st century. Accordingly, if the current military service and personnel system are maintained, it will be difficult to maintain even the number of the Army reduced to 365,000. Nevertheless, the Army has a mission to protect the country from external aggression as the last bastion of national defense. To fulfill this mission, there are ways to improve the military service and personnel system, but there are ways to maximize individual combat power to create one warrior that is worth a hundred and overcome the insufficient number of troops through superior mobility to the enemy. This study studied how to solve the shortage of troops as well as strengthen combat power through a combined combat system that can maximize individual combat power and mobility by applying the latter concept, and further analyzed the future battle environment and suggested the developmental direction of the army's combined combat system.

This paper discusses the characteristics of the fire service organization structure in the Republic of Korea. The subjects of the study were selected by the fire service organization consisting of public firefighters in the Republic of Korea. The characteristics of the fire service organization structure (complexity, centrality, and officiality) were confirmed by various articles and previous references. The fire service organization showed a mechanical structure and bureaucratic organization. The levels of complexity, centrality, and officiality in the characteristics of fire service organization structure were higher than those of a general administration organization or company organization. In conclusion, this paper contributes to the development of fire service organization theory by confirming the characteristics of fire service organization structure.

An important trend in the sustainment of military aircraft is the transition from preventative maintenance to condition based maintenance (CBM). For CBM, it is essential that the actual system condition can be measured and the measured condition can be reliably extrapolated to a convenient moment in the future in order to facilitate the planning process while maintaining flight safety. Much research effort is currently being made for the development of technologies that enable CBM, including structural health monitoring (SHM) systems. Great progress has already been made in sensors, sensor networks, data acquisition, models and algorithms, data fusion/mining techniques, etc. However, the transition of these technologies into service is very slow. This is because business cases are difficult to define and the certification of the SHM systems is very challenging. This paper describes a possibility for fielding a SHM system on legacy military aircraft with a minimum amount of certification issues and with a good prospect of a positive return on investment. For appropriate areas in the airframe the application of SHM will reconcile the fail-safety and slow crack growth damage tolerance approaches that can be used for safeguarding the continuing airworthiness of these areas, combining the benefits of both approaches and eliminating the drawbacks.

In this study, a three-dimensional variational(3DVAR) data assimilation system was developed for the operational numerical weather prediction(NWP) system at the Republic of Korea Air Force Weather Group. The Air Force NWP system utilizes the Weather Research and Forecasting(WRF) meso-scale regional model to provide weather information for the military service. Thus, the data assimilation system was developed based on the WRF model. Experiments were conducted to identify the nested model domain to assimilate observations and the period appropriate in estimating the background error covariance(BEC) in 3DVAR. The assimilation of observations in domain 2 is beneficial to improve 24-h forecasts in domain 3. The 24-h forecast performance does not change much depending on the estimation period of the BEC in 3DVAR. The results of this study provide a basis to establish the operational data assimilation system for the Republic of Korea Air Force Weather Group.
