Offshore wind power generation has significant advantages, including enhanced energy security and job creation. However, despite these benefits, South Korea has not fully utilized its potential in this sector. In contrast, offshore wind power industry development in Europe has been driven by government leadership. Drawing from this experience, South Korea also needs to relax regulations, strengthen necessary infrastructure, and enhance financial support systems to activate the offshore wind power industry. For this, sustained government leadership is absolutely essential. Without addressing the capacity issues in the power grid, we cannot expect offshore wind power generation to succeed. To address grid issues, we propose the enactment of a special law called the "Special Act on Grid Expansion." Considering KEPCO's financial situation, private investment should be encouraged for grid construction. The role of developers is crucial for the successful development and operation of offshore wind power. They manage risks throughout various stages, from site acquisition to construction and operation, which have a significant impact on the success or failure of projects. Since domestic developers currently lack experience in offshore wind power, a cooperative strategy that leverages the experience and technology of advanced countries is necessary. Energy issues should be recognized as important tasks beyond mere political ideologies, as they are crucial for the survival of the nation and its development. It is essential to form a public consensus and implement ways for residents to coexist with offshore wind power, along with the conservation of marine ecosystems and effective communication with stakeholders. Expansion of the offshore wind power industry requires support in various areas, including financial and tax incentives, technology research investment, and workforce development. In particular, achieving carbon neutrality by 2050 necessitates the activation of offshore wind power alongside efforts by major corporations to transition to renewable energy. South Korea, surrounded by the sea, holds significant offshore wind power potential, and it is our responsibility to harness it as a sustainable energy source for future generations. To activate the offshore wind power market, we need to provide financial and tax support, develop infrastructure and research, and foster a skilled workforce. As major corporations transition to renewable energy to achieve carbon neutrality by 2050, offshore wind power must play a significant role. It is our responsibility to fully utilize South Korea's potential and make offshore wind power a new driver of growth.

Providing safety training to construction workers is essential to reduce safety accidents at the construction site. With the prosperity of visualization technologies, Immersive Virtual Reality (IVR) has been adopted for construction safety training by providing interactive learning experiences in a virtual environment. Previous research efforts on IVR-based training have found that the level of fidelity of interaction between real and virtual worlds is one of the important factors contributing to the sense of presence that would affect training performance. Various interactive devices that link activities between real and virtual worlds have been applied in IVR-based training, ranging from existing computer input devices (e.g., keyboard, mouse, joystick, etc.) to specially designed devices such as high-end VR simulators. However, the need for high-fidelity interactive devices may hinder the applicability of IVR-based training as they would be more expensive than IVR headsets. In this regard, this study aims to understand the impact of the level of fidelity of interactive devices in the sense of presence in a virtual environment and the training performance during IVR-based forklift safety training. We conducted a comparative study by recruiting sixty participants, splitting them into two groups, and then providing different interactive devices such as a keyboard for a low fidelity group and a steering wheel and pedals for a high-fidelity group. The results showed that there was no significant difference between the two groups in terms of the sense of presence and task performance. These results indicate that the use of low-fidelity interactive devices would be acceptable for IVR-based safety training as safety training focuses on delivering safety knowledge, and thus would be different from skill transferring training that may need more realistic interaction between real and virtual worlds.

본 연구에서는 우리나라 생태숲조성 기본계획 수립의 실태를 파악하고, 문제점 및 개선방향을 제시 하였다. 우리나라 생태숲조성 계획의 제한요소로는 입지여건, 지형적 측면, 기존식생 등의 문제가 높은 빈도로 나타났다. 토지이용현황은 사유지의 평균 비율이 29.7% 이었으나 실질적인 사업비의 투자는 되지 않은 것으로 나타났다. 도입빈도가 높은 시설은 기반시설, 건축시설, 휴게시설, 편익시설, 안내시설 등 이었으며, 도입빈도가 낮은 시설은 식물재배시설, 생태시설, 상징시설 등으로 나타났다. 식물 종 보유현황은 500종류 이상을 보유한 곳이 1개소이었고, 산림청이 제시한 생태숲조성 기준의 식물종다양성 기준 이하는 11개소 이었다. 사업비는 시설투자비가 식재비보다 매우 높았으며, 후기투자사업비 보다 초기투자사업비 월등히 많았고, 조성 이후의 유지관리에 대한 예산 계획 수립이 거의 없었다. 산림청이 제시한 생태숲조성의 기본 개념은 충실하게 계획 하고 있었으나 세부적인 도입 계획에서는 이용자 중심 위주로 계획 되어져 생태숲조성 기본 취지에 어긋나고 있었다. 이러한 현상은 생태숲조성을 주관하는 지방자치단체가 사업추진을 위한 과정에서는 산림청이 제시한 내용을 제안하고, 사업이 확정된 이후에는 산림청이 제시한 내용을 대부분 무시하여 전시효과를 위한 생태숲조성 방식으로 변화하기 때문이다. 산림청에서 제시하는 생태숲조성을 위해서는 산림청의 감독이 강화되어야 하고, 지방 자치 단체장, 감독부서, 계획 및 설계자 등 담당자들이 생태숲에 대한 명확한 개념 정립을 하여야 할 것이다.

A phase II site investigation and feasibility study was conducted at a military mortar shooting range near the demilitarized zone (Kyunggi, South Korea) to assess the extent of contaminants migration to the nearby Imjin river in which a flood control dam is under construction. The results showed that silty-clay soils around target areas were co-contaminated with heavy metals (Cd, Cu, and Pb) and explosives (HMX, RDX, and TNT). The total amount of contaminant was estimated to be 497.1 kg-RDX, 20.6 kg-HMX, 1.4 kg-TNT, 35.2 kg-Cd, 4,331 kg-Cu, and 5,115 kg-Pb, respectively. Both heavy metals and explosives were almost equally distributed on each soil particle size fraction. Neither subsurface soil samples nor ground water samples showed signs of contamination above the environmental criteria. The major migration route of contaminants was soil particles in surface run-off during rain at which a mass discharge rate of 30.0 mg-RDX/hour was observed.

The purpose of the present study is to analyze and evaluate the performance of a small Darrieus wind turbine installed at the Urumsil region of Deokjeok-do Island in the west of South Korea 50 km away from Incheon. This place has no government electricity so alternate resources of energy needed to be installed there. For this purpose a small Darrieus wind turbine with the capacity of 1.5 kW was developed and installed at the site. The experimental power output of the wind turbine is less than the designed power at the same values of wind speed. This power loss is mainly due to the highly unsteady nature wind of sudden changes in magnitude of wind speed and wind angle. The results of current study can be used to make a future power generation plan for Deokjeok-do and other nearby small islands.

Since the hydraulic fracturing field testing method was introduced first to Korean geotechnical engineers in 1994, there have been lots of progresses in a hardware system as well as an interpretation tool. The hydrofracturing system of first generation was the pipe-line type, and it has been developed to a wire-line system at their second generation. The current up-to-date system is more compact and is able to be operated by all-in-one system. With a progress in a hardware system, the software for analyzing in-situ stress regime has also been progressed. The shut-in pressure, which is the most ambiguous parameter to be obtained from hydrofracturing pressure curves, can now be acquired automatically from the various methods. While the hardware and software for hydrofracturing tests are being developed during the last decade, the author could accumulate the field test results which can cover the almost whole area of South Korea. Currently these field data are used widely in a feasibility study or a preliminary design step for tunnel construction in Korea. Regarding the difficulties in a site selection and a test performance for the in-situ stress measurement at an off-shore area, the in-situ stress regime obtained from the field experiences in the land area can be used indirectly for the design of a sub-sea tunnel. From the hydrofracturing stress measurements, the trend of magnitude and direction of in-situ stress field was shown identically with the geological information in Korea.

대정공원은 운동장과 휴양 위락 시설을 겸비한 운동공원이다. 1910년 당시 부산 이사관 카메야마가 대만으로 이동할 때 그를 기념하기 위한 도시 시설로써 운동장의 건립에 관한 최초의 발의자는 당시 경제인들이었다. 하지만 운동장 건립은 카메야마의 죽음 이후인 1915년 무렵부터는 타이쇼 천황의 즉위 기념사업으로 진행하게 된다. 1917년 부산 부윤의 제안으로 운동장 건립이 본격화하고, 부지 선정 작업에 들어간다. 부지 선정지 후보를 두고 논의되는 과정을 살펴보면 운동장 부지 선정의 조건으로 먼저 운동장에 합당한 유효 부지 면적, 시가지와의 거리 다시 말해서 접근성, 그리고 예산이었다. 수차례의 논의와 실제 부지 조사의 결과, 전염병원이 이전하고 난 뒤 소학교가 들어오기로 한 부지를 공원 부지로 선정한다. 대정공원의 공사비는 모두 부산부민들의 기부금으로 마련하게 된다. 지역 상공인과 회사, 관공서, 지역별로 기부금 모금 위원회를 구성하여 조직적으로 모금하였다. 그 결과, 공사비 전액을 부민의 기부금으로 조성하게 된다. 대정공원은 크게 운동공간과 휴양, 위락 공간으로 구성되어 있었다. 공원의 세 방향에 입구를 두고, 외주는 식재를 하였다. 야구장은 공원의 중앙부에 자리 잡았고, 테니스 코트 2곳도 마련하였다. 일본 스모장도 공원의 북쪽에 마련하였다. 대정공원은 한국 근대 최초의 체육공원이었다. 그리고 공사비 전액을 주민의 모금으로 조성한 것이 특징이다. 1910년 당시 부산에서 운동장을 건립해야만 했던 이유를 밝히는 것이 남은 연구 과제다.
