In this study, we compared the perception of absolute purchase of equipment for broadcasting equipment purchasing demand according to the rapid change of domestic content production and distribution method, and the degree of information such as technical reliability and system stability of domestic broadcasting equipment perceived by consumer The effects were analyzed through a research model. Due to the lack of existing research data on broadcasting equipment demand, we conducted in depth interviews with surveys of broadcasting equipment and surveys. As a result of analysis, compared to foreign equipments, there are many cases of purchase of domestic equipments, systems, and block purchases. To improve the preference and satisfaction of Korean broadcasting equipment, which is recognized by domestic demand for broadcasting equipment, it is urgent to improve the technical reliability and to develop core key equipment and to expand the demand of domestic equipment limited to small power transmitter antenna and monitor equipment. It is urgent to develop in order to develop overseas and to support the domestic market to secure the domestic market.

This study verifies effects of the distribution of fire fighting equipment on the satisfaction of fire fight equipment among fire officers and the mediating effect of the reliability of fire fighting equipment on the relationship between the two variables in order to provide preliminary data on the development of fire fighting equipments. Fire officers from the seven fire stations located in Gyeonggi-do province were selected and surveyed to achieve the purposes of the study. Using AMOS 18.0, structural equation modeling were applied to analyze the data. Major findings are as follows. First, the propriety of the amount of distribution of fire fighting equipment and the timeliness of distribution have positive effects on the reliability of fire fighting equipment. Second, the reliability of fire fighting equipment has a positive effect on the satisfaction of fire fighting equipment. Third, the propriety of the amount of distribution of fire fighting equipment has a positive effect on the satisfaction of fire fighting equipment. It was found that the reliability of fire fighting equipment has a partial mediating effect on the relationship between the propriety of the amount of distribution of fire fighting equipment and the satisfaction of fire fighting equipment.

Weapon systems have been developed with high technology electronic equipment due to technology growth. In addition, the capital, operational and maintenance costs of weapon systems have all increased. However, cost of operation and maintenance for weapon systems has been decreased relatively compared to the increased capital cost of weapon systems. Therefore, the defense industry needs to research the life cycle cost of weapon systems that have high operational and maintenance costs. This paper focuses on maintenance equipment for the operation and maintenance of weapon systems. Recently, it seems that the weapon systems that have periodic calibration with maintenance equipment are valid. The equipment requires periodic calibration by the manufacturer to check its own validation. Basically, customers demand high reliability devices from foreign companies that have qualified in the global market. Therefore, the tools need to be calibrated overseas. In other words, weapon systems are not available when the equipment has to be calibrated overseas because the systems require validation with valid maintenance equipment. A purpose of this paper is to compare the loss costs that arise from the calibration of the equipment overseas and the purchasing cost of the tools. Finally, the research shows the number of equipment that customers need to minimize the cost. This research will help to improve the efficiency of operation of weapon systems and solve the problems associated with the need for maintenance overseas.

해외로 부터 대량의 방위장비 조달이라는 발상은 일본의 주식인 쌀의 수입 이상으로 약간은 당돌하게 느껴지는 사람도 있을 것이다. 그러나 일본으로서는 군사침략을 받는다고 가상한 최악의 사태에, 필요하고도 충분한 방위장비품이 자연스럽게 확보될수 있는 방안을 확립해두는 조치가 바람직하다. 그 구체적이고 실현가능한 처방전으로서 방위장비품을 해외에서 생산하는 구상은 그 의의를 평가받아야 한다. 또한 방위장비품을 국제조달함으로써 우호국간에 강력한 연대관계가 빚어지는 점에도 착안하여야 한다.

The SOLAS ship should carry at least 83 different types of equipment based on the SFI group codes and each of which consists of several to dozens of components. During ship operation, it is necessary to ensure the normal operation of such equipment, and remote maintenance is highly demanded for immediate repair in the event of a equipment fault. This study proposes to find suitable classification system and to derive database structure for remote maintenance of navigation and communication equipment. As a result of this study, the classification system of equipment should be layered into equipment type, model, and component, and main table in the database consists of FMEA, service history, case data through Q&A, Preventive Maintenance. A database was constructed for 140 navigation and communication equipment models and 750 components. In order to evaluate the practical effects, service engineer evaluated the usefulness using the cloud app.

Magnetic separators has been used in the mining and the recycling fields in general, and is still applied in wide variety of fields. It is classified into the equipments for separating coarse ferrous scrap from non-ferrous materials and the equipments for concentrating fine ferromagnetic particles below 3mm. Magnetic separation equipments for concentrating fine materials also falls into two categories of low intensity and high intensity magnetic separators. The former is used for ferromagnetic materials but also paramagnetic materials of high magnetic susceptibility, and the latter for paramagnetic materials of lower magnetic susceptibility. Both low and high intensity magnetic separators could be utilized either dry and wet. Recently, the High gradient magnetic separators(HGMS) used in the range of less than 0.7 tesla has been gradually replaced by the magnetic separator made of rare earth permanent magnets commercialized in the 1980s. In addition, the expansion of nanotechnology in terms of synthetic magnetic materials in the environmental and biological fields is expected to contribute positively to the development of magnetic separation technology.
