The battle vehicle has six types of indicators attached to the instrument panel in consideration of the special battlefield environment. However, many problems of moisture occurred during the operation of combat vehicles. These moisture phenomena can adversely affect aesthetics and functionality. Moisture is generated on the instrument panel due to the inflow of external moist air, the desorption of the moist air inside the parts, and the fluctuation of the dew point temperature. In this paper, we try to derive the root cause of various moisture generation and provide an improvement measures for moisture control. Therefore, the failure mechanism of the instrument panel may be analyzed and the design may be changed depending on the failure factor. Furthermore, the effect of the design change is verified, and the humidity performance is evaluated.

The premature failure of the universal joint connecting the drive gear box and the cooling fan caused a deterioration in serviceability and operability. Universal joint is a device that transmits engine power to a cooling fan. Internal pin breakage and shaft separation can cause secondary damage such as cooling fan malfunction and radiator damage caused by component failure. The purpose of this paper is to analyze the damage phenomenon of universal joints caused by bundles in SPVs and to improve them. In order to verify the improvement, a single part test and a system conformance test were conducted, and durability test was conducted to confirm the improvement effect on the improved prototype. Through these, the effects of increasing the durability of the improved product were estimated.

This study is to investigate the improvement of quality and cost reduction of welding materials for combat vehicles through localization. The existing imported welding wires and localized welding wires were evaluated. The evaluation of the welding wires was performed for the feedability, chemical/mechanical properties, macro testing, and weldability. As a result of evaluation, the localized welding material met all the evaluation standard values. In addition, it showed excellent performance in terms of weldability and feedability. It is judged that the welding quality is improved thanks to the improvement of feeding characteristics through the localization of the welding material, and the fatigue of the worker is also expected to be relieved.

This study is to investigate the cause of the malfunction of the ground tracked combat vehicle rotating roller and set future direction of improvement. The integrity of the initially used plate and rotating roller was evaluated. As evaluation methods, mechanical property test, radiographic test and size checking test were performed.

Through mechanical property test and radiographic test, the materials used initially were identified to be sound. In the evaluation of the selected four polymer materials, it was confirmed that the PET was excellent in the mechanical properties and the water absorption rate. PET is excellent in mechanical properties and water absorption.

본 계획의 목적은 정유재란 남원성전투의 역사적 현장이자 구 남원역 터인 중앙공원에 대한 기본계획과 운영프로그램을 계획하여 남원시의 다른 관광자원과 연계방안을 제시하는 것이다. 대상지의 역사성과 다크투어리즘에 대한 이론적 고찰, 입지여건, 자연환경, 인문환경 등 현황분석, 관련법규 검토, 주민/상인 설문조사 분석을 통해 기본구상안을 도출하고 마스터플랜을 수립하였다. 향후 남원성 북문과 성곽 복원을 고려하여 최소한의 시설을 도입하였다. 성곽 외 지역은 정유재란 당시 4일간 남원성에서 전개되었던 남원성전투를 시계열적으로 상징화하였고 성곽 내 지역은 기존 철도관련 시설을 활용하는 공간을 도입하였으나 남원성 복원 후에는 철거 하고 원형으로 복원하는 것을 전제로 하였다. 부지의 장소성을 기념하고 역사의식 고취를 위한 체험 프로그램을 제안하였고 유사테마와 연계, 인접한 관광자원과의 연계를 통해 관광객 방문을 유도하고자 하였다.

Reliability analysis of the components frequently starts with the data that manufacturer provides. If enough failure data are collected from the field operations, the reliability should be recomputed and updated on the basis of the field failure data. However, when the failure time record for a component contains only a few observations, all statistical methodologies are limited. In this case, where the failure records for multiple number of identical components are available, a valid alternative is combining all the data from each component into one data set with enough sample size and utilizing the useful information in the censored data. The ROK Navy has been operating multiple Patrol Killer Guided missiles (PKGs) for several years. The Korea Multi-Function Control Console (KMFCC) is one of key components in PKG combat system. The maintenance record for the KMFCC contains less than ten failure observations and a censored datum. This paper proposes a Bayesian approach with a Dirichlet mixture model to estimate failure time density for KMFCC. Trends test for each component record indicated that null hypothesis, that failure occurrence is renewal process, is not rejected. Since the KMFCCs have been functioning under different operating environment, the failure time distribution may be a composition of a number of unknown distributions, i.e. a mixture distribution, rather than a single distribution. The Dirichlet mixture model was coded as probabilistic programming in Python using PyMC3. Then Markov Chain Monte Carlo (MCMC) sampling technique employed in PyMC3 probabilistically estimated the parameters’ posterior distribution through the Dirichlet mixture model. The simulation results revealed that the mixture models provide superior fits to the combined data set over single models.

In this paper, we compared and analyzed the performance of the GPS L1/L2 signal with GPS L1 using the navigation system. Generally the GPS receiver calculates the position of the satellite by using the ephemeris data recevied from GSP Satellites, and also calculates the position of its own using the pseudorange. This paper provides an overview of the device which can receive an GPS L1/L2, and compares the GPS L1 with the GPS L2 signal power using the simulator. It was confirmed that the GPS L1/L2 receiver and the GPS L1 receiver met the requirements of standards and it is similar to the navigation performance of the GPS L1 Receiver with the GPS L1/L2 receiver. It was also confirmed that the GPS L2 band can not correct ionospheric error in the navigation system of the combat vehicle.

최근 수년 동안 외국인 전투원의 증가가 서구사회와 국제사회의 중요한 이슈로 떠올랐다. 그 이유는 미국과 서구 유럽국가들을 중심으로 이라크와 시리아 등의 테러조직들이 점령하여 전투를 벌이는 갈등 및 위험지역에 외국인 전투원으로 자원하는 일반인들과 청소년들이 급증하였기 때문이다. 국제사회에서 테러집단으로 규정된 집단과 관련된 전투를 위한 외국인 전투원으로의 가담은 대다수의 국제사회에서 불법화되어있음에도 불구하고 지난 10여 년간 그 수는 전대미문으로 늘어났다. 현재ISIS 등의 테러집단이 근거지를 잃는 등 외국인 전투원의 유입이 줄어들 것으로 예상되고 있으나 여전히 외국인 전투원에 대한 정책적 대응이나 학문적 연구는 필요한 실정이다. 특히 불법 출입국루트 등에 대한 연구들이 필요한 실정이다. 최근 유럽 등에서 경험한 대형 살상의 테러사건들의 배후에 외국인 전투원들이 가담해 있다는 보고가 있듯, 자국 내 외국인 전투원들의 위험성은 상존하며 이들이 전투지역이나 과거 테러리스트 근거지 등을 여전히 여행하며 테러활동에 적극 가담할 위험은 아직까지 높다고 판단되기 때문이다. 따라서 이 연구는 최근의 외국인 전투원들의 현황에 대해 소개하고, 유럽의 프랑스와 네덜란드의 외국인 전투원에 대한 법률적 대응에 대한 분석과 소개를 하였다. 그리고 다양한 학문적 노력을 통해 분석된 외국인 전투원들의 유럽과 중동지역의 불법 이동 루트에 대한 분석결과를 소개하고자 한다. 이를 통해 외국인 전투원들에 대한 이해와 경각심을 높이고 학문적ᆞ정책적 관심을 높이는데 공헌하고자 하였다.

본 연구의 목적은 충격흡수 및 통기기능 인솔을 적용한 개발 전투화의 족저압력 및 온도변화를 연구하는데 있다. 남성 피험자 11명(age: 21.8±2.2 yrs, height: 174.3±3.6 cm, weight: 71.6±8.6 kg, foot length: 261.0±1.0 mm)을 대상으로 총 3종류 전투화의 족저압력 및 온도 변화를 비교하였다: 전투화 A(보급형 일반 전투화), 전투화 B(통기구가 적용된 개발 전투화), 전투화 C(전투화 B에 통기기능 및 충 격흡수용 인솔 적용). 족저압력 측정을 위해 Pedar-X를 사용하였고, 전투화의 내부온도는 휴대용 써미스터의 온도센서를 사용하였다. 전투화의 종류별 족저압력 및 온도 변화결과를 비교하기 위해 일원변량분석 (one-way ANOVA)을 실시한 결과, 첫째, 족저압력 변인에서, 기능성 인솔을 적용한 전투화 C가 전투화 A보다 오른발/왼발 후족부의 최대족저압력에서 통계적으로 유의하게 낮았으며, 전투화 C가 전투화 B보다 왼발 후족부의 평균족저압력에서 통계적으로 유의하게 낮은 압력을 나타내었다. 둘째, 내부온도에서 보행 시작 후 40분경과 시점부터 개발 전투화인 B, C가 일반 전투화인 A보다 낮은 내부 온도를 보였다.

The navy that operates a large size of weapon systems, relatively a small quantity of, in order to minimize the loss of war potential caused by the breakdown of weapon system during long-term naval area of operation assigns allowance parts such as Maintenance Float (M/F), Combat Exchange Components, Concurrent Spare Parts (CSP) and so on to each unit and makes them use the allowance parts. Among them, Combat Exchange Components is being calculated in accordance with heuristic method because there is no standardized method to calculate it differently from Maintenance Float and Concurrent Spare Parts. In this article, more systematic calculation optimization method of it is suggested by selecting the optimum Combat Exchange Components in accordance with integer programming and presenting it, comparing it with the list of Combat Exchange Components calculated by actual heuristic method.

이 논문은 손오공과 제신들 간의 전투에 대한 불교적 독해를 주제로 한다. 서유기는 당 玄奘의 구법여행을 그 소설창작의 모티프로 삼고 있는 바, 이로 인해 전체 여정은 물론 각 장의 이야기와 주제의식 또한 현장의 불교적 실천과 긴밀한 친연성을 갖고 있는 것으로 이해 된다. 또한 서유기는 다양한 불교적 사상들을 문학적 형상으로 녹여내고 통합한 현장으로 이해될 필요가 있다. 孫悟空의 형상 또한 그 탄생, 도술학습, 諸神과의 전투, 서천 여행과정에 서의 역할 등에 있어서 일관된 불교적 메시지가 발견된다. 요마에서 성인으로 승화하는 그 전체적 여정은 유식의 轉識得智의 경로를 밟고 있으며, 각 장의 모험담은 空性의 깨달음이라 는 주제의식의 구현을 지향하고 있다. 이러한 맥락에서 손오공의 형상과 역할을 고찰한다면 서유기에 대해 보다 풍부하면서도 일관된 이해에 도달할 수 있을 것으로 생각된다. 본고에 서는 손오공과 제신의 전투를 자아의 집착과 그 해결을 위한 노력으로 보고 그 의미를 천착 해보고자 한다. 그것은 불교에서 三法印으로 규정하는 無常ㆍ苦ㆍ無我라는 삶의 본질에 대한 부정으로 시작되어, 그 집착에 대한 관찰로 이어지며, 자아의 공성에 대한 발견으로 일단락된 다.

Naval combat system developed in-country is progressing at an alarming rate since 2000. ROK navy will be achieved all vessels that have combat system in the near future. The importance of System Engineering and Integrated Logistics Support based on reliability analysis is increasing. However, reliability analysis that everyone trusted and recognized is not enough and applied practically for development of Defense Acquisition Program. In particular, Existing Reliability Analysis is focusing on reliability index (Mean Time Between Failure (MTBF) etc.) for policy decision of defense improvement project. Most of the weapon system acquisition process applying in the exponential distribution simply persist unreality due to memoryless property. Critical failures are more important than simple faults to ship’s operator. There are no confirmed cases of reliability analysis involved with critical failure that naval ship scheduler and operator concerned sensitively.Therefore, this study is focusing on Mean Time To Critical Failure (MTTCF), reliability on specific time and Operational Readiness Float (ORF) requirements related to critical failure of Patrol Killer Guided missile (PKG) combat system that is beginning of naval combat system developed in-country. Methods of analysis is applied parametric and non-parametric statistical techniques. It is compared to the estimates and proposed applications. The result of study shows that parametric and non-parametric estimators should be applied differently depending on purpose of utilization based on test of normality. For the first time, this study is offering Reliability of ROK Naval combat system to stakeholders involved with defense improvement project. Decision makers of defense improvement project have to active support and effort in this area for improvement of System Engineering.

C. S. 루이스가 『나니아 연대기』의 마지막 작품 『마지막 전투』(1956)에서 그리스도가 유일한 진리와 생명이 된다는 점을 어떻게 작품에 녹여내고 있는가를 고찰할 필요가 있다. 이야기의 전반부는 적그리스도의 출현에 따른 아슬란에 대한 진위 논쟁이 빚은 역설과 아이러니, 점진적 반복 기법을 통해, 사고와 지적 성장이 없이는 적그리스도의 계략에 속아 배도할 수밖에 없다는 통찰력을 제공하고 있음을 확인할 수 있다. 이야기의 후반부인 재림과 새 하늘과 새 땅을 살펴본 결과, 그는 재림과 천국에 관하여 근대주의자들은 인간의 소망 충족을 위해 만들어낸 허상이라고 생각했고, 포스트모더니즘 옹호자들은 천국을 단지 인간의 심리상태에 불과하다고 주장했던 것에 대한 변증으로 나니아의 상징들과 성경의 상징을 조화시켜 천국이 실재한다는 점을 아름다운 이미지로 그리고 있음을 확인하였다. 적그리스도의 옹호자들이 구원은 ‘둘 중 하나’보다는 ‘둘 다 모두’라는 보편 구원설을 훨씬 더 선호하는데 비해서, 루이스는 구원이란 ‘둘 중 하나’의 범주에 속한다는 사실을 고수하고 있다. 기독교는 오직 예수 그리스도 안에 있는 사람에게만 구원이 선물로 주어진다는 사실을 분명히 약속하고 있음을 작중 인물들을 통해 보여주고 있다.

The purpose of this study lies in figuring out the factors of how soldiers' digital games experiences make influence on combat power improvement of the military.. For this study, based on the technology acceptance model, we have analyzed how causation is formed between self-efficacy and the collective-efficacy, perceived usefulness, perceived ease of use and the behavior intention. As a result of validating structure equation modeling targeting the sample of 101 soldiers, self-efficacy on digital game has a significant impact on perceived usefulness, perceived ease of use and the behavior intention. This result implies that soldiers’ digital game experiences have compelling relations on improving combat power of individual, which is a component of the military combat power, and the members of the organization. This study’s result offers an insight for implementing and utilizing small unit war game cyber combat system, which is based on digital games related to improving the military combat power in the future

The ‘Yahweh's Warfare’ theory is the one that has emerged as a important issue in modern missiology. It is a theory first claimed by the church growth theorists from Fuller theological seminary by C. Peter Wagner and accepted mostly in Asia, Africa, and South America. This theory has a strength that it makes the supernatural events of the Bible a real experience and brings the expansion of the Evangelism. On the other hand, I think it lacks the Biblical base and focuses only on overcoming Satan and demons, hence it weakens the main points of the Bible such as the proclamation of the Truth and the salvation of souls. Therefore, it is necessary to put this movement on a sheer balance so that it can be helpful to bearing positive fruits to Christian ministry, based fully on the Bible. This issue was addressed during the Lausanne Covenant and then focused on as main contents at the Manila Covenant in 1989, and at Capetown covenant in 2010. However, the dispute over the issue is not completely solved and is still demanding the full Biblical base. In the same line, in order to understand the spiritual warfare through the Biblical base, the present paper investigates the ‘Yahweh's Warfare’ theory that the Old Testament scholars presented and argues, and that is helpful to basing the spiritual warfare theory to sublimate it spiritually in Christ. Thus, the present paper proposes to present the principles of the spiritual warfare by studying the ‘Holy Warfare’ theory argued by G. Von Rad in 1940’s, the writings of the ‘Yahweh Warfare’ theory and consulting the Old Testament texts regarding the ‘Yahweh Warfare.’ The main points of the Yahweh Warfare theme are: (1) Jehovah is the warrior who wages wars and orders in them; (2) the Christians who participate in the wars should be holy and belong to God fully; (3) the enemy of the spiritual warfare is Satan; and (4) the aim of the Yahweh Warfare is the establishment of the divine kingdom while the spiritual warfare aims to build the kingdom of God. The present paper does not deal fully with the Biblical base for the spiritual warfare, but confines itself to presenting the Biblical base for the spiritual warfare simply through the Old Testament texts on the Yahweh warfare.

This paper’s aim is to suggest the Expert System for analyzing relative combat power in ground operations. Since relative combat power analysis in terms of comparing combat power of friendly forces with one of the enemy can determine how the commander and staffs operate their unit afterwards, it requires fast and rational decision-making process. However, it has relied on manual method so far though Tactical Information Communications Network(TICN) into which numbers of applications can be loaded has been developed over a decade. The Expert System that will be built using EXSYS Corvid tool is expected to lessen error rate, provide faster decision- making, and reflect intangible combat power as well as tangible one by using an appropriate weights in analyzing relative combat power.

One of the most important elements in games is 'fun'. According to the Flow theory, when the proper ability and challenge are combined at the optimum shape, game users can reach the stage of 'fun' with being fully absorbed. MMORPG satisfy the users making them have fun, using tools such as vicarious satisfaction by various role performances of various occupational clusters, self-display and diversity of the story through many quests. This study investigates the composition and characteristics of MMORPG, provide a model which calculates game balance according to the occupations and roles of the game characters and verify the validity by applying this model into the actual game. MMORPG is basically based on human behaviors. That is to say, it is possible to make balance evaluation model because the abilities needed for battle and adventure are within our imagination. For example, in the battle, 'power' is needed basically, 'speed' is also needed for quick movement and skillful technique, 'intelligence' and 'wisdom' are needed for more difficult techniques, 'strength' is needed to live on and 'charisma' is needed to make relationships. Thus, general six abilities are available, and based on these, by itemizing the contents composing the battle, the study attempted to provide the final battle balance evaluation model. Therefore, in order to make balance among these offenses and defenses and to compare the figures by unified ones, ICF (Integrated Comparative Figures) is hereby defined.
