This paper aims to establish a guideline for ridership capacity of different rail vehicles for military passengers. Previous guideline is limited only to a Mungungwha(hauled by diesel locomotive) vehicle, but this paper expands the limitation to ITX- Saemaeul and urban rail vehicles classified to Electric Motivated Unit(EMU). The guideline considers both with and without personal armor conditions, and based on repetitive ridership experiments. The experiments are designed under considerations of the required number of soldiers for the sample spaces of the different rail vehicles. Moreover, the design tries to establish a concept of optimal capacity additionally to a traditional limiting ridership capacity. In order to do this, ridership comfort is questioned to participant soldiers repetitively over the experiments and all answers of them are surveyed as a results of it. The results of the experiments presented by this paper can be referenced to establish a new guideline on ridership capacity for Korean army.

To expand the use of three dimensional(3D) product modelling in the army, we have analyzed military technical data management system, as well as the military guidelines for the unique format and content of technical data package. Because traditional munition sector is based on the machinery and equipment industry, they have usually applied two dimensional(2D) drawings to prepare a design and to make a product. For that reason, there is no provision for 3D product modelling as a technical data package in the military guideline. In this study, we proposed an improvement scheme for the vitalization of 3D product modelling in the army not only in terms of related guideline but also military technical data management system.

In this paper, we consider the military requirement, study the military network services and their related traffic parameters, evaluate the performance the experimental army network and then suggest the design guideline of applying VoIP to the whole military. We evaluate the performance of the delay and loss in the viewpoint of packet and call levels for the several scenarios. First, the performances of separate network service were considered and the satisfaction of the requirement was obtained. Secondly, the delays and losses of the integrated network services were calculated as the amount of the background traffic increases. Finally, based on the simulation results, we presented the design guideline which classified network configurations for applying VoIP equipment and helped estimate the number of VoIP terminals in the existing link.

In this paper, we introduce that MAAB style guideline has effects on the codes generated from Simulink models for static and dynamic software testing, when weapon system embedded software design and implementation are performed using the model based method. As showing the effects, MAAB guideline is helpful for defect prevention related with coding rules and run time errors associated with the DAPA weapon system embedded software guide. Thus, we check related items between MAAB and DAPA software reliability testing including static and dynamic analysis. And then we propose the criterion to select proper items from MAAB for DAPA guideline and show how to verify the relationship and the effects on reliability of models in Simulink. In addition, we show the needs for clear logics in conditional block models or statements and simple complexity models for Simulink model based design.

With the recent rapid growth of RFID technologies, the Application of RFID systems into the medical or the military industries as well as into the distribution and logistics industry are now attempted continuously. The government and private sectors plan to carry out various small and large scale projects related to RFID systems. However, many companies attempting to apply RFID systems applications into their organizations are encountering many several difficulties because of the lack of installation experience and the absence of an useful guideline. This paper focuses on identification and classification of typical barriers to the successful application of RFID systems according to the five-step method of system application process. Moreover a "barrier map" is produced by conducting a survey and interviews by specialists. In addition, a practical guideline to overcome such barriers is presented and discussed.

The purpose of this study is to develop a guideline for user based collection development of the military library. A questionnaire survey of 1,000 soldiers of armed forces selected from two military divisions was conducted. The survey results show the needs for the sufficient collections with diverse subject areas. current materials. and Periodicals. and also suggestion of the programs for encouraging soldiers to read.

Including 425 Program, which is Korean military surveillance and reconnaissance satellite, there were mostly civil-driven space programs in Korea. However, there are increasing numbers of military demand-driven space program in nowadays. Furthermore, it is positive effects on launch vehicle development in Korea that the termination of Korea-U.S. missile guideline. In this paper, it emphasizes the needs of system engineering(SE) management method which meets both defense system's characteristics and space's characteristics. These characteristics are such as non-fixable after the launch, the security issue in defense system. And it also introduces SE tool, methodology and its philosophy. There are several functions that data management, issue management, risk management, and technical requirement management. Also describing its implications and direction of improvement.

The military has adopted and implemented risk assessment since 2013 to reduce fatalities and accident rates at construction sites. However, risk assessment is carried out as a voluntary preventive activity and is maintained as a superficial administrative process for owners. Risk assessment must comply with the Occupational Safety and Health Act and the Enforcement Guideline of Risk Assessment. However, the scope of the assessment covers many industries, including manufacturing and distribution, making it difficult to apply to construction sites. As a result, the guidelines are interpreted and applied differently at each construction site. This study aims to improve the risk assessment system so that it is applicable to construction projects and proposes the improvement of the risk assessment system by analyzing the current status of serious accidents in military construction projects.

The purpose of this research is to propose a maintenance support system for deciding assembly sequence of the product and appropriate tools that are used to assembly and disassembly of parts in the product when geometric properties of the product. The digital maintenance system (DMS) is developed to generate the maintenance guideline and the initial experiment is conducted especially for an underwater weapon system with cylindrical structure. DMS considers four factors to find the efficient assembly and disassembly procedure automatically: (1) assembly tree, (2) properties of each part, (3) distance from the center of the product, and (4) volume. Based on the factors, DMS simulate the movement of each tool virtually and the properties of tools are investigated to find an appropriate tool for using assembly and disassembly of each part in the product. The proposed approach integrates modeling, simulation, data configuration, and virtual reality to allow a development of preliminary maintenance guidance.

The vaccine is biological pretreatment that improves immunity to a particular disease. We can get immunity from producing antibody with injection antigen which has ability to defense against the disease. The ELISA is the most widely used method to measure antibody titer. We have developed and performed validation of ELISA according to the guideline of KFDA and ICH. In this paper, we have verified ELISA method is an excellent method to measure the titer of anti-PA antibody. We have constructed recombinant protective antigen among anthrax toxins and used as antigen of ELISA. In this validation, we have evaluated precision (repeatability, interlaboratory precision), specificity, linearity(range) and LOD, which are validation articles suggested by guideline. Inter-person precision was replaced with inter-laboratory precision. From the results, we have confirmed high precision in all experiments with CV under 20%.
