  • 우주전파환경이란 지구 전리층, 열권, 자기권 및 행성간의 공간 등 통칭한 전파 전달 환경을 말하며 주로 태양의 활동에 영향을 받는다. 태양은 막대한 복사 및 입자 에너지를 방출하여 지구의 자기권과 전리층에 영향을 주어 방송 통신, 전력, 항법, 위성 등 여러 분야에 걸쳐 피해를 줄 수 있다. 그러므로 우주전파에 취약한 국가주요시설을 분류하여 따로 지정하고 관리해야 한다. 본 논문에서 우리나라의 국가 주요시설은 "국가기반시설", "국가주요시설", "국가보안목표 시설"로 크게 3가지로 조사하였다. 국가중요시설은 "적"이라는 위기요인으로부터 보호해야할 대상이며, 보안 목표시설은 "파괴/태업/비밀누설"이라는 위기요인으로부터 보호해야 할 대상이다. 즉, 국가주요시설과 보안목표시설은 위기요인에 의해 정의된 시설이다. 하지만 국가기반시설은 위기요인이 아니라 r 피해가 국가적으로 핵심적인 시설들로 정의된다. 따라서 우주전파재난을 위한 보호체계는 가장 포괄적인 국가기반시설의 테두리에서 다루어야 한다.

  • Despite the continuous installation and regular inspection of waste treatment facilities, complaints about excessive incineration and illegal dumping stench continue to occur at on-site treatment facilities. In addition, field surveys were conducted on the waste treatment facilities currently in operation (6 type) to understand the waste treatment process for each field, to grasp the main operating factors applied to the inspection. In addition, we calculated the material·energy balance for each main process and confirmed the proper operation of the waste disposal facility. As a result of the site survey, in the case of heat treatment facilities such as incineration, cement kilns, and incineration heat recovery facilities, the main factors are maintenance of the temperature of the incinerator required for incineration and treatment of the generated air pollutants, and in the case of landfill facilities Retaining wall stability, closed landfill leachate and emission control emerged as major factors. In the case of sterilization and crushing facilities, the most important factor is whether or not sterilization is possible (apobacterium inspection).In the case of food distribution waste treatment facilities, retention time and odor control during fermentation (digestion, decomposed) are major factors. Calculation results of material balance and energy resin for each waste treatment facility In the case of incineration facilities, it was confirmed that the amount of flooring materials generated is about 14 % and the amount of scattering materials is about 3 % of the amount of waste input, and that the facility is being operated properly. In addition, among foodwaste facilities, in the case of an anaerobic digestion facility, the amount of biogas generated relative to the amount of inflow is about 17 %, and the biogas conversion efficiency is about 81 %, in the case of composting facility, about 11 % composting of the inflow waste was produced, and it was comfirmend that all were properly operated. As a result, in order to improve the inspection method for waste treatment facilities, it is necessary not only to accumulate quantitative standards for detailed inspection methods, but also to collect operational data for one year at the time of regular inspections of each facility, Grasping the flow and judging whether or not the treatment facility is properly operated. It is then determined that the operation and management efficiency of the treatment facility will increase.

  • This study shows the result of the security assessment of the nationwide key energy facilities and suggests the ways of improving the security level. According to the study, most of the energy facilities are adequately equipped with physical security factors such as security personnel, security systems, fences, and guard posts, but lack of awareness is pervasive among those concerned, so the security operation is inefficient. In other words, inefficient deployment of security personnel, lack of the fundamental knowledge of the security systems, excessive dependence on surveillance cameras' functions such as Pan/Tilt/Zoom, misplaced cameras, low efficiency of monitoring, and irrelevant security plans. To solve these problems, above all, the authority concerned need to develop professional training programs to secure certified security mangers, and need to standardize security process to ensure consistency and to harness the standardization as a source of self assessment to improve security level.

  • A heat pump system using the thermal effluent from the Jeju thermal power plant of KOMIPO was constructed with the capacity of 300 RT to supply cool or hot water to greenhouse facilities located 3 km from the power station. The way of transporting heat from the thermal effluent to greenhouses at a long distance was optimized, and a monitoring system to measure the water temperature and detect a leakage in a pipe conduit was also installed. This paper presents the system configuration of the constructed heat pump system for air conditioning and heating of greenhouse facilities in Jeju, and the characteristics of major components deployed in the system. The preoperational tests of the heat pump system were conducted during the summer season in 2018 for evaluation of its cooling performance. The operational stability and cooling performance of the heat pump system were confirmed by investigating the measured fluid temperature and flow rate, and COP of the heat pump in a cooling mode.

  • With the enactment of the "Framework Act on Carbon Neutrality and Green Growth to Cope with Climate Crisis," various sector-specific plans are being implemented to achieve carbon neutrality. School facilities are mandatory buildings for the "Zero Energy Building Certification" and are the buildings that account for the highest proportion among public institution buildings. Therefore, they play a major role in achieving carbon neutrality in the construction sector. This study analyzed the recent energy use trends and zero energy levels in varied ways to promote the spread of building energy management systems and to provide basic data for efficient operation management and investigated the effectiveness and user opinions of the Building Energy Management System (BEMS) applied to school facilities.

  • The increase in the amount of energy used in the agricultural sector due to the expansion of agricultural machinery and greenhouse horticulture has caused a range of problems, such as an increase in the cost of input, such as heating costs and greenhouse gas emission. To overcome these problems, this study examined the current status of energy use in greenhouse horticulture as well as the change patterns of non-taxable oil and agricultural electricity, and reviewed the current status of the supply of renewable energy and energy saving facilities for agriculture. This study investigated the area of advanced and renewable energy and energy saving facilities implemented, applied the energy saving ratio of advanced and renewable energy and energy saving facilities, and determined the effects of renewable energy in the agricultural sector, such as increase in production, decrease in heating cost, reduction in Government financial expenditure, reduction in greenhouse gas emission, and oil substitution effect.
