지구 온난화와 무분별한 도시 개발은 농촌 및 자연 지역에 비해 도시에서의 수문 피해를 야기하고 있는 현실이다. 특히 우리나라의 6~8월에는 태풍과 강우가 집중적으로 발생하여 도시 지역에서의 위험성이 증가하고 있다. 1990년대 이전과 달리, 2000년대 이후에는 태풍과 강우로 인한 집중적인 호우가 도시 지역의 잠재적 내수침수 위험을 높이고 있는 실정이며 이에 대한 대책이 중요하다는 것은 현실로 다가왔다. 국지적인 호우는 최근 우리나라에 자주 발생하고 있어, 도시지역의 홍수 피해가 증가하고 있으며, 특히, 서울은 급속히 발전한 도시 중 하나로 2010년, 2011년, 2012년, 2022년에 홍수로 인한 도시 침수로 인명과 재산 피해가 크게 발생했다. 현재 우리나라는 도시 지역을 대상으로 개별 시설물에 대한 방재성능평가를 수행하고 있으나, 방재성능평가 기법 미흡에 따른 평가 결과의 신뢰성 부족으로 방재성능평가 수행에 어려움이 있다. 시설물뿐만 아니라 유역에 대한 방재성능평가 및 도시 통합적인 면적 개념의 방재성능평가 기법 개발이 필요하다. 도시 지역은 인구와 재산이 밀집되어 있어, 집중적인 호우에 의한 피해 노출 및 홍수에 대한 취약성이 증가하고 있어 지자체별 방재성능목표 강우량 설정에 대한 문제점을 검토하고, 지역 특성을 반영한 방재성능목표 설정 및 활용 개선을 위한 방안이 필요하다. 따라서, 각 시·군에 적용되고 있는 도시 방재 시설물의 평가에 대한 현재의 운영 상황과 문제점을 검토하고 이를 바탕으로 방재성능평가를 향상시키기 위한 개선 방안을 제시하였다.

During the transportation of chemicals, quantitative risk assessment for chemical leakage accidents caused by traffic accidents was carried out and the appropriateness of chemical transportation route was evaluated. The quantitative risk assessment method applied to the chemical leakage accidents that may occur in the chemical handling equipments installed in the workplace was presented and applied to the chemical transportation. By analyzing the number of traffic accidents in transportation vehicles, the probability of chemical leakage accidents during chemical transportation was predicted and applied to the quantitative risk assessment of chlorine gas leakage accidents that may occur when transporting liquified chlorine bombe using vehicles. As a result, the most appropriate route of transporting the liquefied chlorine bombe was suggested on the basis of risk.

선박조종시뮬레이션의 평가항목 중 운항자[주관적] 평가는 선박조종 시뮬레이션을 선박운항자가 안전진단대상사업으로 인하여 느끼는 심리적 부담 또는 위험도를 평가하는 것이다. 해상교통안전진단 시행지침 상 운항자[주관적] 평가의 결과가 평균-2.0이상인 경우 해상교통환경 변화에 따른 통항 및 접이안 안전성 확보가 가능하다고 평가하고 있으나 정성적인 평가기준 -2.0에 대한 명확한 근거가 부족하였다. 이에 본 연구에서는 현재까지 제출된 진단보고서 중 116건의 시뮬레이션 결과 나타난 운항자[주관적] 평가값을 사업대상별로 분류하여 톤수, 선종, 입출항별 분석을 통한 문제점을 도출하고 이에 대한 기술기준 개선(안)을 제시하였다.

This study was carried out in order to verity the usefulness of FSA(Formal Safety Assessment) methods as a tool to conduct a safety assessment of general cargo ships flying the Korean flag, and to provide useful information on 'the Safety of General Cargo Ships' for IMO committee's discussion on the matter at a future session. In the previous paper, "A Study on High-level FSA for Korean-flagged General Cargo Ships(1)", the concepts of the FSA methodology and its five steps were described and the results of Hazard Identification(Step 1) and Risk Analysis(Step 2) from the FSA study for the Korean-flagged general cargo ships were discussed. Subsequent to the Steps 1 & 2, the identification of Risk Control Options(RCOs-Step 3) for eliminating or reducing either the frequency or the severity of the risks identified and their Cost-Benefit Assessment(CBA-Step 4) were undertaken. In this paper, the results of the Steps 3 & 4 are discussed, and some recommendations are made.

This study analyzed the state of the vessels which were using the berth for dangerous goods more than its carrying capacity in the major dangerous cargo handling port of Ulsan in Korea, The result of the analysis showed that a ship which has 3 times more than the maximum berthing capacity was moored at berth. Accordingly, a simulation model for 50,000 DWT berth was built and carried out the mooring safety analysis with 50,000 DWT, 70,000 DWT and 100,000 DWT vessels by mooring assessment program. The evaluation was carried out according to the standard environment presented in OCIMF standards. 50,000 DWT vessel was evaluated to meet the acceptable criteria but, 70,000 DWT and 100,000 DWT vessels exceeded the acceptable limit as per external conditions. Consequently, safe mooring guidelines were suggested and also proposed the building of common 'Mooring safety guideline' for port with assessment of different cases.

Recently, forest soil sediment disasters resulting from locally concentrated heavy rainfall have been occurring frequently in steep slope areas. The importance of landslide hazard map is emerging to analyze landslide vulnerable areas. This study was carried out to develop HyGIS-Landslide based on Hydro Geographic Information System in order to analyze forest soil sediment disaster in the mountainous river basin. HyGIS-Landslide is one of HyGIS components designed by considering the landslide hazard criteria of Korea Forest Service. It could show the distribution of landslide hazard areas after calculating the spatial data. In this system, the user could reset the weight of hazard criteria to reflect the regional characteristics of the landslide area. This component provided user interface that could make the latest spatial data available in the area of interest. HyGIS-Landslide could be applied to the surveyor's compensation score and it was possible to reflect the landslide risk exactly through it. Also, it could be used in topographic analysis techniques providing spatial analysis and making topographical parameters in HyGIS. Finally the accuracy could be acquired by calculating the landslide hazard grade map and landslide mapping data. This study applied HyGIS-Landslide at the Gangwon-do province sample site. As a result, HyGIS-Landslide could be applied to a decision support system searching for mountainous disaster risk region; it could be classified more effectively by re-weighting the landslide hazard criteria.
