오염물질을 실시간으로 측정해 배출사고를 예방할 수 있는 원격측정시스템(TMS : Tele-metering System)이 폐수 배출사업장에도 도입된다. 환경부는 오는 2007년까지 1~3종 배출업소와 하$\cdot$폐수종말처리시설 등 2,443개 폐수배출사업장에 오염물질 측정기기를 부착해 환경관리공단에 설치될 관제센터에 연결한다고 밝혔다. 이를 통해 한해 동안 배출되는 폐수의 86.2%가 실시간으로 관리될 전망이다. 배출사업장은 폐수의 특성에 따라 유량계, 자동시료채취기, 생물학적산소요구량(BOD)$\cdot$화학적산소요구량(COD),$\cdot$총질소(T-N)$\cdot$총인(T-P)$\cdot$부유물질(SS)측정기기 등을 최소 1종부터 최대 7종까지 설치해야 한다. 그러나 자동측정이 어려운 총대장균군수$\cdot$색도$\cdot$노르말헥산 등은 수동측정법을 유지키로 했다. 업체별로 최대 1억7천~2억원까지 예상되는 설치비는 사업자의 부담을 덜기 위해 융자 지원할 계획이다. 이에 본지에서는 그 내용을 간략히 파악해 보고자 한다.

The purpose of this study is concerned with the development of production for heavy industrial and militaries weapon systems in the field of industries and militaries in Korea. In managing the discontinuance and obsolescence of components and systems. Particularly, defense heavy industries are supporting the designs and production of heavy and weapon systems. Therefore, it is more realistic to manage the discontinues of components and systems, but Heavy and Militaries supports the maintenance of the weapon systems from the maintenance and repairs stage, Discontinued management are imperturbable reality and are moving to be reactive. In order to maintain and operate expensive heavy and weapon systems, it is necessary to manage the Total Life Cycle supportability of the components and systems. Proactive management should be preceded by active management rather than reactive management. In addition, the Information Systems will make you suitable management systems.

Although the weapon systems are becoming more diverse and complex, they are progressing in a short development period and a longer test and evaluation period. The more difficult the given environment is, the more efforts and performance of quantitative target values can be made by development agencies to carry out stable projects. However, these target values of the Integrated Logistics Support are not specified in the requirements and being set during the system development phase. In this paper, application of MOEs, MOPs and TPMs for ILS are presented and provided the basis for carrying out systematic Verification & Validation activities. As a result that MOEs of the ILS were chosen as Availability and MOPs as Mission Reliability, Logistics Reliability, Maintainability and Supportability and TPMs as MTBF, MTBCF, MTTR and so on. In particular, it is appropriate tailoring and apply the TPMs considering the cost, schedule, scope of work and characteristics of the project.

The South Korean Navy has operated Harpoon guided missiles through step-by-step acquisition after adopting them for the first time in 1978. As Harpoon guided missiles have been operated for a long time, it is necessary to make an active follow-up logistics support to guarantee their performance. Inspection of guided missiles is a basic activity to check the status of missiles. This study was conducted to check if the existing inspection interval of Harpoon guided missiles that have been operated for a long time was appropriate. Regarding research methods, based on the Navy's field operation materials, this study analyzed and presented inspection interval by section according to the period of operation, utilizing the Martinez's theory and a non-parametric MCF technique.

ROK Navy Landing Ship Fast(LSF-II) is equipped with special equipment that is not compatible with other combat ships due to special missions. So there are almost no maintenance capabilities except for simple repair parts replacement and maintenance parts. The researcher determined that the way to solve these problems was to apply Performance Based Logistics (PBL), and reviewed the cases of PBL applications abroad and domestically. To confirm the current maintenance capability, we visited LSF-II operation unit to identify maintenance capabilities for each mounted equipment, and interviews with operators and maintenance practitioners confirmed the limitations of outsourcing maintenance and the need to apply PBL. In order to analyze the effect of PBL application, the measure of effectiveness and measure of performance were selected based on the opinions of LSF-II operation/maintenance practitioners and PBL experts and the practical experience of this researcher. A survey was conducted on operation/maintenance practitioners and professional personnel. Based on the survey results, the effect of applying PBL was analyzed using the AHP technique, and an efficient PBL application plan was proposed for LSF-II.

The thermal image system was widely used in the defence-related industry because of detect infrared light from the object without light. but, as the demand in the security system and automobile market increases, the civilian industry are expanding to the private sector. There are difficult to apply various requirement because of previous systems are based by FPGA, so it need new system that apply to various requirement. The proposed paper is thermal image processing system using common image processor. It has various requirement and scalable to support image input/output interface and device driver. If it is used to proposed system, it reduce development cost and period than previous system based FPGA. Because there has very high accessibility. In addition, it expect to have satisfaction of customer requirements, development cost, development period, release date of product.

The primary aim for using a Korean Condition Based Maintenance (CBM) system is to maintain military operational readiness using Interactive Collection Analysis Systems (ICAS) installed on naval vessels. Other aims are to preemptively provision maintenance and supply functions, to guarantee economical management of logistical assets, and to implement data driven equipment life cycle management. In order to accomplish these aims, it is necessary to establish standard system conditions. However, because manufacturers do not provide the technology necessary for maintenance management, it is required to retain component performance maps for each piece of equipment, and to accumulate data about frequently occurring fault patterns. This study confirms the validity of component performance maps using micro gas turbines and provides accumulated data on machine break downs. This would allow real time equipment performance checks and present performance trends. Then analysis would provide solutions for maintaining the best machine operating conditions with detailed maintenance manuals for operators. This study is a basis for further research to investigate additional ways to develop CBM using data obtained from naval vessels used in actual military operations.

The structure of the fire control system(FCS) of a light armed helicopter and effective logistics support was taken into account in the proposed common weapon interface module(CWIM) for a distributed FCS. The pros and cons of a distributed FCS and a centralized FCS were analyzed, then a CWIM which can be applied to the weapon interface module of a distributed FCS was designed and fabricated. Integration tests between the proposed CWIM and a weapon simulator were conducted to ascertain whether or not the proposed CWIM could be applicable to a distributed FCS. We expect that the CWIM design approach method secured through this study will be helpful in mitigating cable work of the FCS which will be applied to a Light Armed Helicopter and controlling various weapons.

In this paper, the development of an automotive thermal imaging camera providing image information for ADAS (Advanced Driver Assist System) and autonomous vehicles is described and an improved technique to enhance the details of the image is proposed. Thermal imaging cameras are used in various fields, such as the medical, industrial and military fields, for the purpose of temperature measurement and night vision. In automobiles, they are utilized for night vision systems. For their utilization in ADAS and autonomous vehicles, appropriate image resolution and enhanced detail are required for object recognition. In this study, a $640{\times}480$ resolution thermal imaging camera that can be applied to automobiles is developed and the BDE (Block-Range Detail Enhancement) technique is applied to improve the details of the image. In order to improve the image detail obtained in various driving environments, the block-range values between the target pixel and the surrounding 8 pixels are calculated and classified into 5 levels. Then, different factors are added or subtracted to obtain images with high utilization. The improved technique distinguishes the dark part of the image by the resulting temperature difference of 130mK and shows an improvement in the fine detail in both the bright and dark parts of the image. The developed thermal imaging camera using the improved detail enhancement technique is applied to a test vehicle and the results are presented.
