방산물자의 품질 개념에서 강조되어야 할 중요한 관점은 신뢰성 문제이다. 궁극적으로 방산물자의 품질보증은 납품 당시의 품질보다는 요구된 운영기간 중 고장률을 일정 수준 이하로 유지하며 장비를 효율적으로 유지할 수 있는냐하는 신뢰성에 그 초점이 맞추어져 있다고 하겠다. 또한 양산단계의 품질문제와 불가분의 관계를 갖고 있는 개발단계에서의 품질보증 문제와 배치운영단계에서의 사용자 불만처리와 사용자 만족도 제고를 위한 방안을 제시해 보았다.

In or to generate high electric power in increasing demand, power station should operate facilities to meet requirement. The scale of electric power equipment is increasing in both size and complexity. With unexpected accidents at power facilities or power stations happening, substantial socioeconomic losses in an industrial society is caused. A major cause of unexpected accidents is deterioration of dielectrics, isolating two conductors electrically. In order to detect the deterioration processes of power cables, the operation status of power cables should be monitored on a regular basis. We have invented and installed equipment at Korea Western Power Co., Ltd., located in Taean, in order to predict and prevent the deterioration status of dielectrics destruction of power cables. The main line in Y-connection to the secondary coils of transformer delivers electric power to the external devices. The equipment we developed is the one measuring insulation resistance of cables operation in on/off status with respect to the main line. We present the equipment in terms of operation and configuration of hardware side.

Due to economic development and advancement of medical science, an aging society where the proportion of the elderly population increases is coming. Korea's aging speed is growing rapidly compared to that of other developed countries. The physical and mental abilities of elderly people with aging are getting worse more and more. They want a kind of auxiliary system in order to mitigate and prevent their weakness. The supplementary system can greatly contribute to improving the quality of life for elderly people. In particular, some devices that include muscle strengthening and cognitive and balance ability enhancement are useful for the most older people. In this paper, we introduce a development of human care contents based rehabilitation equipment to enhance these functions, and present its usability evaluation. The evaluation is conducted for rehabilitation specialists as well as expected users and their results are analyzed.

Printed circuit boards (PCBs) are a key component widely used in the production of electronic products, and not only quantitative growth but also qualitative developments such as integration cannot be ignored. Wave soldering equipment is commonly used equipment at manufacturing sites, but it is impossible to configure a dedicated equipment environment suitable for each PCB specification during the preliminary research and prototype development stage. It is neither suitable for development within limited time line nor manufacturing various product groups because only equipment setting conditions can be changed within a given time. In this study, we introduce a case of introducing a PCB pallet to enable selection of optimal process conditions within the limited environment described above. In addition, by presenting a discriminant that can determine in advance whether production is possible with current general-purpose equipment, it is expected that problems that may arise due to limitations in the general-purpose wave soldering equipment environment can be identified and resolved in advance. Ultimately, this palette makes it possible to shorten the development period and improve productivity.

Parts obsolescence is a component type, in which raw materials or parts that make up a weapons system, are developed and produced according to demand, but they age due to changes in technology or market conditions. The weapon system equipment currently being used by the military is having difficulty in procurement, maintenance, and operation because of the obsolescence of parts. Parts obsolescence during the life cycle of a weapons system affects not only the combat readiness of the military but also the economic loss of material, parts, and equipment manufacturers and suppliers. On the other hand, advanced technology has reduced the life span of electronic components that make up the weapons system. In addition, because of the nature of the weapons system, the obsolescence of components takes decades from development to disposal, which has a serious adverse effect on equipment readiness and life cycle costs. Therefore, it is necessary to manage systematically the parts obsolescence from development until the disposal of the weapons system equipment. This study examined the system of component control in developed countries to present a proper management plan for local situations and propose development plans for the early settlement of component control.

Applying Visual Art to pop music performance is gradually increasing. A video editor which simply mixes a number of images was mainly used in the past, but now various computer software make it easy to control visual art by development of computer technology, and it became possible for you to express unique and inimitable idea as well. Compare that a complicated equipment which makes them spend much expense and time was only used in the big size of concert hall in early days, a small and simple one now helps you easily apply your idea to Visual art in Pop music performance even in the small club. The technic of Visual art is being developed gradually especially by using computer The point of this study is how to apply real-time interaction between sound and visual image to interactive media art.

The cloud computing industry is regarded as a key element of the ICT industry and an important industry that will be a watershed for the future development of ICT industry. Korea has established the 1st~2nd cloud computing development basic plan to induce the growth of the cloud industry. However, the domestic information security guide provides technical vulnerability analysis criteria for Unix and Windows servers, DBMS, network equipment, and security equipment, but fails to provide vulnerability analysis criteria for hypervisors that are key elements of cloud computing. Organizations that have deployed cloud systems will be able to assist in vulnerability analysis using the criteria presented in this paper.

The development of electronic technology brings the advent of GPS and electronic total station which measures, stores and records automatically angles, distances and 3d coordinates Electronic totalstation is the surveying equipment and system2000 is the supporting program that enables totals tation to get 3d terrain information, construction of the database and automatic drafting of the cartographic map. In this study, we aims at studying the system which can produce automatically the digital cartographic map by using total station and system2000. For this study, cartographic maps of a region are produced by total station and system2000, and then builded digital cartographic map on the autocad2000 environment and also we analysed two digital cartographic maps. As a results of this study, it is found that digital cartographic map by total station and system2000 are much more accurate and efficient than cartographic map by electronic plan table surveying.
