Test equipment for strain and vibration measurement was designed for educational purposes. Widely available and affordable materials were put into making this device. Three strain gauges placed on an iron ruler made cantilevered beam were used to measure values according to external load. An electromagnet triggered excitation and a function generator created vibration of the beam. We present three different tests conducted with this equipment regarding production of scales, measurement of resonant frequency, and calculation of the difference between excitation frequency and measured frequency. Overall, this paper presents a piece of simple yet inexpensive test equipment and its corresponding portfolio with expectations of being applied to the educational field for efficient measurement of load and vibration.

Among the five promotion strategies of Defense Innovation 4.0(DI 4.0), the military structure/operation optimization strategy aims to innovate the military structure based on advanced science&technology(S&T), and to integrate advanced S&T in the field of defense operation such as education&training and human resource development. As the future battlefield expands to AI-based unmanned/robot combat systems, space, cyberspace, and electromagnetic fields, it is necessary to train officers with the capabilities required in these battlefields. It is necessary to develop capabilities from junior officers who will lead the future battlefield to operating core advanced power based on the 4^th industrial revolution S&T. We review the education system of the military in universities and propose a method of redesigning the education system that is compatible with DI 4.0 and can develop technology-intensive capabilities based on advanced S&T. We propose a operation plan of major and extra-programs that can develop the capabilities of junior officers required for the future battlefield, and also suggest ways to support the army's practical training.

2006년도 9월에 조사된 가축통계에 따르면 국내 산란계 사육수수는 5,500만수로 국내 1인당 산란계 1마리 이상이 사육되고 있다. 하루 1개의 알이 생산되고, 국내 수출입되는 물량을 배제한다면 1인당 하루 1개의 계란을 섭취할 수 있는 양이다. 소비자들은 계란이 인류가 발견한 최고의 완전식품으로 50g의 고단백 영양덩어리라고 잘 알고있다. 하지만, 2003년 조류인플루엔자의 발생으로 당시 계란의 오염 가능성을 제기하면서 생산에 비해 소비가 떨어지는 추세가 나타나고 있으며, 언론을 통해 계란의 안전성 문제가 자주 제기되고 있는 실정이다. 이와 관련하여 본회에서는 계란에 대한 잘못된 오해를 풀고자 국방대학교 안보과정 교육생 일행을 초청해 조인(주)의 Grade Packing Center(등급포장센터)를 방문하여 농장에서 생산된 계란이 어떻게 위생적으로 포장납품되는지를 둘러보는 기회를 마련하였다.

This paper examines several inefficient problems generated from a management process of defense acquisition system, and suggests several alternatives to remedy the current acquisition-related problems. This might help MND to reform the current DAPA's acquisition system. The offered elements are to, first, redefine function of mid-term plan & budget allocation between MND and DAPA, second, devise economic acquisition management and force development to build integrated management system of requirement-acquisition-operation & maintenance, third, build Workforce Management Act(WMA) and Professional Education System(PES) for strengthening expertise and institutionalizing manpower rotation of requirements & acquisition-related fields, fourth, implement weapon systems' Total Life Cycle Systems Management(TLCSM) and improve developmental & operational test and evaluation. These are essential elements in minimizing confusion & conflict emanating from surrounding acquisition program among MND-DAPA-Each Services.

Recently, in the defense field, efforts are being made to collect data by building data centers to incorporate artificial intelligence technology. Weapon system training data can be used as input data for artificial intelligence models and can be used as high-quality data to maximize training performance and develop military strategies. However, training data contains personal information such as the names and military numbers of the personnel who operated the equipment, and training records that reveal the characteristics of the weapon system. If such data is passed on to the enemy, not only the specifications and performance of the weapon system but also the proficiency of each operator may be exposed. In this paper, we propose a pseudonym processing methodology for education and training data security and also suggest a direction for revising related laws.

The Republic of Korea Army (ROK Army) is currently developing the Army Synthetic Battle Training System (ASBTS) by 2026 and will use it to advance division-level LVC integrated training. This study proposes a way to improve the effectiveness and efficiency of training by applying VR/AR technology to the ASBTS. To this end, we analyzed cases of VR/AR technology use in the defense field in advanced countries and the ROK military. As a result, we confirmed that the effectiveness and efficiency of training can be improved when the training system is converted to an immersive system. Accordingly, we selected and presented defense training subjects to be applied to VR/AR technology, considered the development direction for applying VR/AR technology to the ASBTS, and proposed a way to apply VR/AR technology to the ASBTS.

The AR/VR-based education and training system is expected to contribute greatly to accident prevention and budget reduction as well as practical training effects similar to the battlefield environment. Research to use AR/VR for learning is ongoing, and technology can be improved without experiencing failures that can occur in the real world. Major advanced countries in defense recognized the advantages of AR/VR technology early on, and developed and utilized systems using them in various fields, from mastery of individual weapon system operation to comprehensive combat training systems, war history education, and post-traumatic stress treatment. Therefore, the purpose of this study is to examine the cases of AR/VR application education and training in advanced defense countries and to draw implications for the South Korean military.
