  • Since Dr. Lipke announces earned schedule management(ESM) in 2002, it has been used in project management to make up for the insufficient schedule management function of earned value management technique. However, it is difficult to accurately forecast the schedule of delayed defense research and development(R&D) projects with the ESM technique. Therefore, this paper proposes a new schedule forecasting method considering the progress of delayed work in ESM technique. This concept can also be adopted to the traditional project progress management (PPM) technique. We verify the effectiveness of the proposed concept through several defense R&D projects and prove that it is possible to supplement the schedule forecasting of the ESM and PPM technique.

  • Unexpected massive disasters have occurred around the world, causing enormous socio-economic damage. The military has long been enacting laws, organizing organizations and establishing systems for crisis and disaster management, but it did not consider the situation when military essential functions were suspended due to unpredictable and massive disasters. With the September 11 terrorist attacks, the U.S. military has developed COOP strategy aimed at continuing military essential functions in all crisis, and is contributed to national continuity by ensuring uninterrupted national security functions. Korean military has established a crisis and disaster management system, but focuses on managing and controlling disasters and crisis situations. Korean military needs a system to guarantee military essential functions even in national crisis beyond its management capabilities. In this study, We compared and reviewed the U.S. administration and military COOP guidelines and directives, ISO22301 international standards., and developed planning guidelines suitable for the Korean military situation by responding to detailed items based on ISO22301. In particular, the U.S. military(DoD, Army, Navy, Air Force) COOP guidelines were drawn and incorporated into the guidelines(such as protection and succession of command authority, the fulfillment of essential functions and operational security, etc.). The planning guidelines are expected to be used as reference materials for the introduction of COOP systems in the military and the establishment of plans in the future.

  • The sand table training is one of the most effective training method in military operations which can accomplish missions such as simulation and rehearsal without limitations related to time, space, money and so on. Previous sand table training has many problems like that the sand table cannot represent real field condition because of its physical properties. So, it is hard to be preserved and impossible to include much of information into them. In this paper, we make an approach based on Augmented Reality(AR) to solve these problems and propose an efficient military training briefing tool with virtual sand table environment described as actual battle field Virtual Tactical Map(VTM) can realize a virtual military training with simple action like moving marker or tangible interface by hand. Real-time state information of VTM gives us more organic intelligence for entire situation. Tangible AR interface provides users with a contents authoring tool that is natural, intuitive and easy to deal with as interaction between user in real world and system that augmented real world with virtual object. VTM is a newly designed military training briefing tools. A military training content can be reproduced and it is possible that user uses this content later. Thus, it shows us potential possibilities of AR applications on military leaning field.

  • Problems caused by the U.S. military bases have attracted little attention until recently due to the national security of S.Korea and the peace of North-Eastern Asia, emphasized from the perspective of macro-geopolitics. However, since the political regime has been democratized and political discourses have been liberalized from the 1990s, those problems become a nation-widely serious social issue, though they have been brought about on the local areas. Thus, it can be suggested that micro-geopolitics is highly relevant and significant in approaching the local problems caused by the U.S. military bases, and ultimately resolving the macro-geopolitical problem of longstanding unfair relations in the SOFA and the withdrawal of U.S. troops. This paper aims to consider local problems caused by the U.S. military bases and resolving strategies from the perspective of micro-geopolitics. First of all, it discusses some significance of the micro-geopolitical perspective, as it has been recently emphasized in political geography in considering local problems and politics of life on the basis of place, then looks on empirically criminal and environmental problems caused by the U.S. military bases, analyses the questionnaire date on the perception of local dwellers around the military camps in Nam-gu Daegu, and finally suggests strategies to resolve those problems, which level up from the micro to the macro-scale of geopolitics.

  • In the existing deterministic network, the capacity of each arc has been assumed to have a determined property. In reality it may have a property which cannot be determined, and even if it is determined, it contains many errors. Fuzzy theory is efficient in dealing with these kinds of properties. The object of this study is to show that the capacity of each arc and the goal quantity have fuzziness and to develop a new method of determining the fuzzy maximal flow quantity.

  • This study is the descriptive research tried in order to identify how the air force soldier's ego-resilience, positive affect, negative affect of air force soldiers on their military life stress. and a survey was conducted targeting 321 air force soldiers. The results of this study found that the subjects average scores in terms of ego-resilience, positive affect, negative affect, military life stress were 3.11, 3.16, 2.26 and 1.94 points, respectively. The factors of ego-resilience and positive affect showed significantly positive correlation, but the factors of negative affect and military life stress showed some negative correlation. The ego-resilience indirectly influence on the subjects' military life stress through the positive and the negative affect, not directly influenced on them. And the positive and the negative affects directly influenced on the subjects' military life stress. Therefore it needs to reduce soldiers' military life stress by developing a program to enhance soldiers' ego-resilience and to do more positive emotional experiences.

  • Background: Breast cancer (BC) is the most common cancer among females in Turkey. Predictors affecting the breast self-examination (BSE) performance vary in developing countries. Objective: To determine the frequency of BSE performance and predictors of self-reported BSEs among women in the capital city of Turkey. Materials and Methods: This cross-sectional study was conducted on 376 Turkish women using a self-administered questionnaire covering socio-demographic variables and BSE-related features. Results: Of the participants, 78.7% (N=296) reported practicing BSE, whereas 9.5% (N=28) were implementing BSE regularly on a monthly basis, and only 5.7% (N=17) were performing BSE regularly within a week after each menstrual cycle. Multivariate logistic regression modeling revealed that BSE performance was more likely in younger age groups [20-39 years] (p=0.018, OR=3.215) and [40-49 years] (p=0.009, OR=3.162), women having a family history of breast disease (p=0.038, OR=2.028), and housewives (p=0.013, OR=0.353). Conclusions: Although it appears that the rates of BSE performers are high, the number of women conducting appropriate BSE on a regular time interval basis is lower than expected. Younger age groups, family history of breast diseases and not being employed were identified as significant predictors of practicing BSE appropriately. Older age and employment were risk factors for not performing BSE in this sample.

  • Background: The aim of this study was to determine beliefs concerning breast self-examination in first- and second-degree relatives of patients with breast cancer and evaluate their breast self-examination (BSE) application. Materials and Methods: A survey study was conducted in an oncology polyclinic and general surgery clinic of a hospital in Ankara, the capital of Turkey with a sample of 140 women. Results: It was determined that 60.7% of the participants had conducted BSE and 48.1% had undergone a clinical breast examination. Perceived selfefficacy of the women who performed BSE were significantly higher compared with women who did not practice BSE (p<0.001) Furthermore, perceived barriers were lower among those who had performed BSE (p<0.001). Logistic regression analysis indicated that women who perceived higher self-efficacy (OR: 1.119, 95% CI: 1.056-1.185, p<0.001) and had regular CBE (OR: 8.250, 95% CI: 3.140-21.884, p<0.001) and educational status (OR: 5.287, 95% CI: 1.480-18.880, p<0.01) were more likely to perform BSE. Conclusions: Findings from this study indicated that perceived barriers, perceived self-efficacy, and educational status could be predictors of BSE behavior among the first- and second-degree relatives of patients with breast cancer. Therefore, BSE training programs that emphasize self-efficacy and address perceived barriers are recommended.

  • The purpose of this research is to analyze the gamma ray shielding effect of heavy concrete containing magnetic aggregate and to confirm the applicability to the military protective facilities. In general, a military concrete structure protects combatants from bullets, and also it provides some radiation shielding. In this research, experiments were conducted using a Cs-137 source to check the gamma ray shielding effect. In addition, the Monte Carlo N-Particle(MCNP) modeling was applied to evaluate the gamma ray shielding effect of a military structure. As a result, as the concrete thickness increased, the shielding performance improved according th the linear attenuation law. With that, as the ratio of magnetic aggregate was increased, gamma ray shielding performance was also improved. Therefore, this research verified that the application of magnetic aggregate concrete to military facilities for radiation shielding purposes would be useful.
