The purpose of this study is to investigate the historical progress about Teukgongmusul as bodyguard martial arts focused on security service history through the meaning of its development and expansion. This study used secret materials from presidential security service, military service headquarters and special merit unit in Korea, and also used interview materials by oral history. For the above tasks, the conclusions of this study are as follows: Firstly, consideration about the background and circumstances of Teukgongmusul when it was developed in 1970s. No.606 special merit unit's soldiers who worked in presidential security service in Korea organized Teukgongmusul. Secondly, consideration about the meanings of Teukgongmusul presented through its development and expansion process. Teukgongmusul was bodyguards' martial arts which was based on Army's martial arts in 1970s. For this reason, Teukgongmusul now has the perception as Bodyguard Martial Arts. Thirdly, consideration about the expansion process of Teukgongmusul when it was adopted in Army and presidential security service in Korea. In 1970s special merit unit was included in presidential security service in Korea where Teukgongmusul was developed. Afterward Teukgongmusul was expanded in two different ways which were Army and presidential security service in Korea. In Army Teukgongmusul was expanded by no.5 special merit brigade and was expanded by Hapkido master who was worked as martial arts instructor for presidential security service in Korea. Fourthly, the historical progress of Teukgongmusul as bodyguard martial art was influenced by the political situation.

KVMF(Korean Variable Message Format) 1.0 protocol is the Army's standard tactical datalink protocol that defines standard messages and communication methods to enable data communication between various weapon systems through bitwise variable message processing. The protocol has been applied to a variety of Army weapon systems over the past decade and has contributed to upgrade the Army's operational capabilities by enabling the implementation of Network Centric Warfare (NCW), the core of modern warfare. Since the KVMF 1.0 protocol was applied, new weapon systems with new technologies have been introduced over time, and new weapon systems have new messages based on the characteristics of the weapon system. As a result, compatibility problems arose due to different message versions with existing weapon systems, and it was expected that these problems would continue to emerge in the future, considering the need for continuous message revisions. Therefore, it became necessary to solve this problem, so this paper proposed a KVMF 2.0 protocol design that guarantees compatibility between forward and backward versions. In this paper, we implemented the design as SW, and confirmed that the design worked successfully by test between forward and backward versions on test environment. Therefore, when the KVMF 2.0 protocol design is applied to a weapon system, we can expect that the weapon system can be compatible with the forward and backward versions working with the existing weapon systems as well as with the future weapon systems.

The domain of entrepreneurship has been dotted across various paradigms. Identifying and examining entrepreneurial intention and propensity to it spontaneously require the insight from the lens of psychological approach. The aim of this study is to examine the influence and impact of psychological factors on entrepreneurial intention; as it is found that in Bangladeshi context several entrepreneurship studies are undertaken, still the exploratory research on interplay between the psychological factors (i.e., self-confidence, locus of control, need for achievement, and tolerance for ambiguity) and entrepreneurial intention has been merely found. The study has chosen Bangladeshi university students as the unit of analysis and the ultimate sample size in this research is n=265. The current paper is a quantitative study where sampling method is followed by convenience sampling technique, and study data is collected through survey questionnaire. Data has been compiled into SPSS whereas, for hypotheses assessment, Smart PLS software is applied. The results reflect that self-confidence, locus of control, and need for achievement are revealed as contributory determinants of entrepreneurial intention while tolerance for ambiguity is found as an insignificant predictor. The current research is expected to offer an in-depth understanding about the significance of psychological factors in examining entrepreneurial intention.

NCOs of the amy-navy-air force are the foundation in maintaining, developing and leading the army making manpower aquisition very important. Currently, the operation or the recruitment business is being overlapped by each training institutions leading to uneffectively decreasing the curiosities of the applicants regarding their future. Even though the NCO selection policy is strong in the aspect of retaining uniqueness, use of acquired specialist, and statute revision, it is showing insufficiency in publicizing, selection effectiveness, promotion of peoples' conveniency, and budget reduction. Therefore, if the unification regarding the recruitment of each military sectors are run by the MMA(Military Manpower Administration), which is the institute that is fully responsible for the recruitment duty, it can acquire excellent man power while decreasing effort and resources, provide accurate information to the NCO applicants on time, and provide improved services through the convenient facilities and systems.

A mortar system is able to be fired more rapidly and concentratedly than other field gun systems. A mortar system can be easily manufactured because of its simple structure. It has also been supporting for the fire power of infantry because it can be carried conveniently. But a mortar system has demerits that are the limited firing range, poor accuracy and uncomfortable operability. Korean army plan to be operated rapidly and enlarge battle field in the near future. So weapon systems of Korean army must have longer firing range, automatic laying function and precision firing capability. This study suggests efficient developing concept of 120mm self-propelled mortar system through surveying the technical readiness level of current R&D and manufacturing ability.

In this study, It is assumed that customers are both usage unit of spare parts and stores of displaying and selling the goods that are installation unit of having the spare parts. The demand pattern through the effective order of spare parts and issue list in installation unit is investigated based on the assumption. Current ASL (Authorized Stockage List) selection of the army has been conducted in the way of using the analysis result of real usage experiences on spare parts used during the Korea War. For this study, ASL selection criteria and procedures based on army regulations and field manuals are specified. Since the traditional method does not presents the association analysis on spare parts used for the current equipment operating and does not have the clear criterion and analysis system about the ASL selection, in order to solve these problems, it was carried out that the association rule is employed for analyzing relationship between the effective order and issue list of the spare parts in point of the spare parts between usage unit and occurring month about purchase spare parts based on the star-schema table. Finally the new ASL selection way using the analysis result is proposed.

This study investigates and analyzes the diversity of menu in military meal services that are recognized by the soldiers who are familar with meal services and, suggest the implications on the results of the analysis. For the ranks of respondents in terms of demographic features, the sergeants were 43.2%(186), the corporals were 29.7%(128). It was identified that the diversity of menu had significant influences as 57.5%. Thus, for the satisfaction on the kitchen and mess hall service, the sanitary condition was the most considerable factor as 41.6%. Next, water supply facilities, sewer hygiene and towels in washstaynds were the issues to be considered more. In conclusion, this study was limited only to the air soldiers in Chungcheon. Then, the future study needs to expand the samples more than this study to apply the results to the entire army. Moreover, the study could not be actively performed because of the particularity of the army. Consequently, it is required to make these kinds of researches dynamically performed like for any other meal service industries.

With the rapid evolution of communication technology, it became possible to overcome the spatial and temporal limitations faced by humans to some extent. Furthermore, the quality of personal life was revolutionized with the emergence of the personal communication device commonly known as the smart phone. In terms of defense networks, however, due to restrictions from the military and security perspectives, the use of smart phones has been prohibited and controlled in the army; thus, they are not being used for any defense strategy purposes as yet. Despite the current consideration of smart phones for military communication, due to the difficulties of network configuration and the high cost of the necessary communication devices, the main tools of communication between soldiers are limited to the use of flag, voice or hand signals, which are all very primitive. Although these primitive tools can be very effective in certain cases, they cannot overcome temporal and spatial limitations. Likewise, depending on the level of the communication skills of each individual, communication efficiency can vary significantly. As the term of military service continues to be shortened, however, types of communication of varying efficiency depending on the levels of skills of each individual newly added to the military is not desirable at all. To address this problem, it is essential to prepare an intuitive network configuration that facilitates use by soldiers in a short period of time by easily configuring the strategy network at a low cost while maintaining its security. Therefore, in this article, the author proposes a Zigbee-based local strategic network by using Opnet and performs a simulation accordingly.

This paper reconsiders the users of iron arrowheads from Mongchon Earthen Wall(夢村土城). Because the Mongchon Earthen Wall has been seen as a major dwelling fort of the Hansong Period(漢城時代 : 18 B.C.~475), Paekche(百濟), these iron arrowheads have been considered as artifacts of the Hansong Paekche with no systematic analysis since they were found in 1985. However, uncovering numerous Koguryo artifacts, the excavations in 1988 and 1989 showed that Koguryo(高句麗) army had occupied the Mongchon Earthen Wall after they had conquered Hansong Paekche. In this paper, focusing on the formal similarity between these arrowheads and those from other Koguryo sites, I attempt to reconsider the nature of arrowheads from the Mongchon Earthen Wall. Found from a small pit, all of these arrowheads (88 in number) seem to have been contemporaneous. While all are stemmed, they can be divided into nine types on the basis of the shape of body and point. Most types are equal or similar to Koguryo arrowheads of other regions, and especially type F and G have not been found in southern Korean Peninsula. Accordingly, it is suggested that the existing models be reconsidered, and that Koguryo army who had conquered Hansong Paekche used these arrowheads around mid-5th century AD. Although at this point it is difficult to determine the users of these arrowheads only by analyzing several formal attributes due to Korean archaeology's little understanding of the arrowheads of the Three Kingdoms Period(三國時代), I expect that application of natural scientific methods will contribute to a better understanding.
