A vulnerability assessment is essential for the efficient operation of a physical protection system (PPS). Previous assessment codes have used a simple model called an adversary sequence diagram. In this study, the use of a two-dimensional (2D) map of a facility as a model for a PPS is suggested as an alternative approach. The analysis of a 2D model, however, consumes a lot of time. Accordingly, a generalized heuristic algorithm has been applied to address this issue. The proposed assessment method was implemented to a computer code; Systematic Analysis of physical Protection Effectiveness (SAPE). This code was applied to a variety of facilities and evaluated for feasibility by applying it to various facilities. To help upgrade a PPS, a sensitivity analysis of all protection elements along a chosen path is proposed. SAPE will help to accurately and intuitively assess a PPS.

The Ministry of Trade, Industry and Energy is now placing emphasis on the importance of a new and renewable energy resource map service as an essential means of promoting the dissemination and adoption of renewable energy and other related industrial activities. To raise satisfaction with the new and renewable energy resource map service and promote its utilization, a survey was conducted on a sample group with an academic research background, i.e. employees of the Korea Institute of Energy Research (KIER) who have a thorough understanding of the technological concepts behind the new and renewable energy resource map. Statistical analysis of the survey results showed a high level of overall satisfaction with the web service for the new and renewable energy resource map. Therefore, it was concluded that the development of practical contents rather than the enhancement of web service convenience is required. A statistically significant trend was also observed whereby, the longer the professional career of the survey respondents, the greater their perception and utilization of, and satisfaction with, the enhanced service, which indicates that their level of understanding and utilization of technological concepts corresponds to their research experience record. In addition, the results obtained from the questionnaires regarding the evaluation of the utilization value of the resource map service indicated that use of the service was equally high in terms of political, business and academic applications. The results confirmed the need to develop multidimensional resource map contents that can be applied to as many fields as possible, rather than focusing on a specific terrain.

The fulcrum of economic development is a sustainable supply of electricity. Nigeria is plagued with blackouts, with one of the lowest per capita electricity consumption in the world (circa. 120 kWh per capita). Hence, policies have been instigated to integrate electricity generation from nuclear power plants (NPP) on or before 2027. However, a critical requirement for NPP generation is the implementation of robust human resource development (HRD) programs. This paper presents the perspective of Nigeria in assessing human resources needs over the entire NPP lifecycle following the milestone approach and employing the IAEA's Nuclear Power Human Resource (NPHR) modeling tool. Three workforce organizations are in focus including the owner/operator, regulators, and construction workers following three decades timeframe (2015-2045). The results indicate that for the study period, a maximum of approximately 9045 personnel (73% construction workers, 24% owner/operator, and 3% regulators) should be directly involved in the NPP program just before the commissioning of the third NPP in 2033. However, this number decreases by about 73% (2465 personnel including 94% operator and 6% regulator) at the end of the study timeframe. The results can potentially provide clarity and guidance in HRD decision-making programs.

In this study, the development and production of electric vehicles and hydrogen vehicles are presented as a method for realizing carbon-neutral. Accordingly, the demand and need for development of underground metal mineral resources such as copper and nickel has increased. The research was carried out using MT survey, which is very useful for deep exploration such as mineral resources and oil exploration because of it's low cost and explorable depth. In Korea, there are very few cases of MT exploration in terms of mineral development, so the study was conducted based on the MT exploration conducted previously in AusLAMP, Australia. Through comparative analysis of the MT exploration data conducted to identify the ore body in the deep area of the Olympic Dam in Australia, with the data directly calculated in 2D inversion, it was confirmed that it can have a positive effect on the possibility of resource development and carbon neutrality using MT exploration in Korea.

Comparative evaluation of offshore wind retreival software, which use the satellite images taken by Synthetic Aperture Radar sensor; SARTools of CLS-SOPRONO, France and SpaceEye of London Research and Development Corporation, Canada is carried out. For a reference satellite image, ENVISAT ASAR imagery of Jeollanam-do Wan-do area when the winter-time northwestern wind prevails is processed by CMOD_IFR2, CMOD4, CMOD5 algorithms. Wind speed difference and its relative ratio are calculated to evaluate uncertainty of software selection.

환경영향평가 연구의 목표(국가환경정책법에 명시)는 개발사업에 대한 여러가지 인자들(생태적, 경제적, 사회적)을 사업이 결정되기 전에 고려하여 사업이 진행되도록 허용하는 것을 확보하는데 있다. 말하자면, 목표는 환경영향평가를 계획과 정책과정에 통합하는데 있다. 국가환경정책법이 시행된 지 25년이 된 오늘날에 그러한 통합의 방향으로 진행의 정도에 관해서 문의하는 것은 적절하다. 이글은 미국의 대평원지역에서의 자원개발사업과 관련하여 계획과 정책과정에서의 환경영향평가에 대한 역할을 검토한다. 특히 에너지 추출 및 변환사업과 관련한 사회경계적 영향과 사업평가, 지방과 지역계획, 주정책개발에서의 환경영향평가에 대한 역할을 설명한다.

최근 글로벌 에너지 공급 위기로 인해 국제 에너지 시장에서 불확실성이 증가되고 있다. 이러한 시장 변화로 에너지 가격이 상승하고 있으며, 미개발된 에너지 자원이 풍부하게 저장된 극한지(북극권)까지 개발 대상 지역이 확대되고 있다. 북극권은 기존 에너지 플랜트 사업을 수행하던 지역과 차별되는 자연환경, 법, 제도, 문화, 이해관계자 등 특수한 건설 환경을 가지고 있기 때문에 사전에 개발지역에 대한 다양한 검토가 필요하다. 본 논문에서는 최근 비전통 에너지 자원개발이 활발히 이루어지고 있는 캐나다 앨버타(Alberta)주를 대상으로 건설 환경 관련 공간정보를 수집하고 구축하였다. 또한, 건설 환경 공간정보 데이터를 활용하여 자원개발을 위한 최적 입지 평가 모델을 개발하고, 기존 자원개발 지역과 비교·분석하여 신뢰도를 검증하였다.
