  • A began of this study is to verify Spontaneous Acoustic Field Reproduction System(SAFRS), developed as an embodiment of creating agreeable sound environment, with evaluation on the field application. SAFRS is a system to sense changes of surroundings and produce sounds, which can go well with environment elements sensed by the system in to the space. The sound which can go well with environment elements is sound which judged by individual evaluation to be so, the classification of the preferred sounds according to the mood of the space was suggested in the former study. So, SAFRS was applied into the Square of D University to evaluate effectiveness of the system. The executed evaluations were 1) evaluation on sounds perception, frequency, volume and matchability with the space, 2) image evaluation on the square and sound environment and 3) evaluation on sound environment with existing sounds, fountains sound, sound produced by SAFRS, and both fountains sound and sound produced by SAFRS. Verifying SAPRS of field application was deduced from those evaluations. Theresultsofthestudyarefollowing: Though the system was applied into the space, the volume of the sounds shouldn't be too high. And with visual surroundings, the effectiveness of the system would be increased. At the results of four evaluations, the result of day evaluation is; both fountains sound and sound produced by SAFRS>fountains sound>sound produced by SAFRS>existing sounds, the result of night evaluation is; sound produced by SAFRS>both fountains sound and sound produced by SAFRS>fountains sound>existing sounds and these results pointed out that sounds environment produced by the system was highly evaluated due to less background sounds.

  • This paper presents an evaluation of the interruption costs for commercial customers in Korea using customer survey methodology. When various research results are examined, the evaluation of direct interruption costs becomes much more simplified. Especially, in the case of commercial customers, it is known that the evaluation of direct interruption costs is more useful. Accordingly, this paper selected the customer survey method to evaluate the interruption costs for commercial customers in Korea considering interruption and customer characteristics.

  • As Cyber threats are rising, the scope of information Security (IS) is extending from technical protection of a single information system to organizational comprehensive IS capability. The ministry of National Defense (MND) has established the IS evaluation for defense organization in 'the Directive for Defense Informatization Affairs.' However, no information about an evaluation method, process and organization is provided. We surveyed information security management system (ISMS) and related best practices in public sector and other countries, and analysed the military information security affairs. Thus, this paper recommends the IS evaluation method and process. The trial IS evaluation is in progress this year and the MND will expand this IS evaluation to the entire organization.

  • In this study, evaluation system of the thermal properties of the exothermic agents was investigated. Exothermic agents property evaluation system was developed by metering variation of power supply. Thermal properties of exothermic agents was affected by material mixture condition of exothermic agents, however, it was not affected by temperature. It is possible to make various exothermic agents by means of regulating thermal properties which is based on property evaluation system of exothermic agents.

  • Purpose: Test & Evaluation items are main contents which verify performance of the development system and they are deduced going through project management system stages. However, there is no systematic or standardized framework for Test & Evaluation items, so a lot of differences occur between projects and people are questioning whether verification items are selected for the optimization of the development system. In this regard, this research proposes the process of deducing Test & Evaluation items in a systematic way during a development stage by applying QFD (Quality Function Deployment) technique which reflects customers' requirements. Methods: Test & Evaluation items are recognized as customers' requirements, and QFD technique which refines and gathers various requirements of customers effectively during general products' development stage is applied to complete HOQ (House of Quality) Conclusion: There is no specific methodology for Test & Evaluation items, so currently, they are selected by including items which are given by similar projects or higher authorities. However, by utilizing QFD technique, selection of evaluation items which goes through more systematic process is expected to be possible.

  • In this study, the evaluation items related to the effectiveness evaluation of the LVC (Live, Virtual, Constructive) training system of the Air Force were derived and the weights of each item were analyzed. The LVC training system evaluation items for AHP (Analytic Hierarchy Process) analysis were divided into three layers, and according to the level, 3 items were derived at level 1, 11 items at level 2, and 33 items at level 3. For weight analysis of evaluation items, an AHP-based pairwise comparison questionnaire was conducted for Air Force experts related to the LVC training system. As a result of the survey, related items such as (1) Achievement of education and training goals (53.8%), (1.2) Large-scale mission and operational performance (25.5%), and (1.2.1) Teamwork among training participants (19.4%) was highly rated. Also, it was confirmed that the weights of evaluation items were not different for each expert group, that is, the priority for importance was evaluated in the same order between the policy department and the working department. Through these analysis results, it will be possible to use them as evaluation criteria for new LVC-related projects of the Air Force and selection of introduction systems.

  • In this paper, we have proposed a methodology which can test and evaluate on system level in development phase of command guided missile system. Test and evaluation play a significant role in the development of weapon system, providing the means for determining to what extent the weapon system satisfies its requirements, whether it functions normally in the operational environment. In case of command guided missile having seeker, the missile communications link provides data to allow the missile to fly an efficient trajectory toward target. Therefore, it is very important to test and evaluate for data link between missile and radar on whole system aspect. we introduce the concept and devices for system level test and evaluation of command guided missile system.

  • For university facility and space management to be public, and to increase the administrational efficiency, this research suggests an efficient as well as an objective evaluation system/index to allow national and university finances to contribute towards higher education. According to the result of this study, evaluation system for university facility can be widely divided into two categories; quality and space management. First, quality management is subdivided into three groups in order for quantitative management, school site and building area, secured building, and financial affairs and expense management. In order for an effective and appropriate space management, the second category of space management proposes seven subdivisions. Based on these subdivisions, quality management on university facility contains 10 evaluation items with marking system which allows perfect score of 50 points. The space management category contains 19 evaluation items and the marking system allows perfect score of 100 points. Therefore, this study developed total of 29 evaluation items for university facility management with marking system that allows perfect score of 150 points. The suggested evaluation system and items will be used as a valuable foundation for efficient and objective university facility management.

  • Variable Message Sign(VMS) is one of the most popular travel information system. In this study, the evaluation categories, each category's datum value and evaluation procedure for enhancing the visibility of VMS are studied and the physical evaluation system is developed. The evaluation categories have been developed based on the analysis of previous guidelines used in Korea, Europe and the United States. The evaluation categories include luminance, luminance ratio, beam width, color, and uniformity. The physical evaluation system consists of goniometer, solar simulator, luminance meter, sensor and rack system. As a result of this study, the quantitative and effective evaluation of VMS visibility would become possible.
