The construction industry generates the greatest number of disasters. Laborer injury at construction sites is mostly reported by small and mid-sized construction sites. Moreover, of the injuries, the greatest number is related to formwork. The objective of this study is to propose a checklist of the risk factors of formwork, in which industrial injuries occur most frequently in small and mid-sized construction sites, with which safety management can be done thoroughly. Risk factors and preventive measures are derived by analyzing 9,396 industrial disasters occurring at construction sites in Korea. The checklist drawn in this study was reviewed by five specialists in safety management, and applied to construction sites to verify its applicability. In a result, applying the checklist to the site showed that the safety management system of small and medium-sized construction sites were insufficient. It is expected to contribute to the effective safety management of small and mid-sized construction sites.

오늘날 수자원 관리의 중요성과 관심이 매우 커지는 가운데 신뢰도 높은 수문자료의 생산은 매우 중요하다. 나아가 기후변화에 따른 집중호우 등을 고려했을 때 효율적인 수문자료 확보를 위해 수문관측소에 대한 객관적인 평가지표와 지점 중요도, 현장에서의 측정 및 하천환경 변화 등의 다양한 검토가 선행되어야 한다. 본 논문에서는 환경부 2019년 낙동강 수계 측정지점을 대상으로 관측소의 객관적인 평가지표, 즉 관측소 설치목적에 따른 지점 중요도(하천 대표 유역, 홍수 및 갈수 예 경보, 유지유량, 갈수모니터링 등)를 고려한 관측소 평가를 실시하였다. 아울러 각 지점에 대한 측정경험과 하천환경 변화에 대한 모니터링 자료를 바탕으로 측정 지점의 난이도와 관측소 변화 여부에 대한 평가 항목을 7가지로 분류, 평가하였다. 단순히 현장경험과 실용성에 중점을 둔 평가항목은 다소 주관적인 판단이 들어갈 수 있기 때문에 의사 결정 과정에서 데이터에 대한 가중치를 부여할 수 있는 엔트로피 기법을 적용하여 관측소 평가결과에 반영하였다. 그 결과 관측소 중요도가 높은 필수 지점 뿐 만 아니라 현장 여건이 고려되지 못한 지점들, 지점 특성에 따라 이설 및 관측망 조정이 필요한 지점도 다소 존재하였다. 효율적인 측정지점 선정을 위해서 관측소의 설치목적 뿐 만 아니라 설계홍수량이나 하천설계기준 수립 등의 객관적인 평가지표와 하천환경 변화 나아가 경제성 검토 등 다양한 요소의 추가적인 연구가 필요하다고 판단된다.

As the demand for hydrogen increases, the facilities for storing hydrogen has been important, and a few laws for hydrogen facilities should be complied. According to the Occupational Safety and Health Act in Korea, in case liquid hydrogen with a storage capacity of 5 tons or more is handled, a Process Safety Management (PSM) system should be complied. However, there are some standards which are not proper for flammable low-temperature liquefied substances on the current Occupational Safety and Health Act. In this study, 7 key points in process safey information and safety operation procedures among PSM components are suggested and how these key points should be improved is derived based on scientific analysis.

This study analyzed the 91 cases of the statements for the Sea Area Utilization Consultation according to the developmental projects of ports and fishery harbors for 2012 2014 and the status of the record of document, and suggested the improvement way to go. The marine environmental timpact assessment items both marine chemistry such as water quality, sediment and marine biology such as benthic animal, plankton, and fisheries show highly rate of site survey. But, the utilization of those data through site survey is too low, and it is necessary to adopt the QA/QC for the reliability of survey data. The items of marine physics such as tide, tidal current analyzed based on references not a site survey. However, the simulation performed actively without calibration and verification compared to the result of site survey. When the projects of port and fishery harbor perform, it is necessary to monitor the physical parameter such as wave, tide and tidal current especially. Based on the scale and the type of project, we need introduce the system of scoping for prediagnosis the key assessment items and checklists.

The purpose of this study is to suggest an improvement plan for the waterfront by conducting an empirical analysis of users of the city's waterfront. For this purpose, this study conducted a field investigation and questionnaire survey on the waterfront of Sincheon, Daegu Metropolitan City. Based on this, this study investigated the importance and satisfaction levels of environmental factors according to the purpose of using the waterfront and proposed the improvement plans through an ISA(Importance-Satisfaction Analysis). The analysis results are as follows. In the case of using the waterfront for exercise, 'The division of bicycle trails and promenades' had the highest level of importance, while satisfaction level for items with 'Convenience facilities such as vending machines, toilets and water fountains' was found to be the lowest. In the case of using the waterfront for leisure and relaxation, 'Tree shade' had the highest level of importance, and the satisfaction level of the item on 'Whether to hold events such as exhibitions' was lowest. The ISA results showed that when the waterfront was used for the purpose of exercise, leisure and relaxation, items such as 'Convenience facilities such as vending machines, toilets and water fountains', 'Cleanliness of space and water quality' and 'Water quality management' had a high level of importance, but had a low level of satisfaction, which suggests that they should be improved on a preferential basis. Next, items requiring intensive improvement for exercise purposes were 'Tree shade', 'Rest facilities such as benches and pergolas', 'Width of bicycle trails and promenades' and 'The division of bicycle trails and promenades'. Leisure and relaxation found that 'Lighting facilities' require improvement. It is expected that if a river improvement project is implemented based on the above results, effective financial commitment and investment will be made.

The purpose of this study is to use long-term water quality monitoring data from tributaries of the Nakdong River system to identify problematic substances in tributaries by examining the rate of exceedance and increase in water quality targets. In the Nakdong River system, monitoring is conducted once a month for 38 tributaries that require intensive management, and this data was used to analyze trends in exceeding and increasing target water quality at each point. The analysis items are eight items that can be evaluated based on river water quality standards: DO, BOD, COD, TOC, SS, total phosphorus, fecal coliform, and total coliform. As a result of the analysis, the target water quality exceedance rate was more than 50%, and the items with an increasing trend were TOC, fecal coliform and total E. coli counts, and the items with an exceedance rate of less than 50% but an increasing trend were SS. TOC is believed to be caused by an increase in non-degradable substances, and the continued increase in Total Coliform will require management of Total ColiformTotal Coliform in effluent water from sewage treatment facilities in the future.
