산업재해의 직접적인 원인은 작업자의 불안전한 행동과 작업과정에서의 안전시설 설치미흡으로 인한 불안전한 상태로와 기술적, 교육적, 관리적 원인의 복합적인 형태로 발생되는데 그 가운데 산업안전보건법상의 건설공사 각 공종 별 기술적인 안전시설설치 기준이 건설업 종사자에게 쉽게 적용하기가 현행 법기준에는 문제점이 있으며 이러한 복잡한 법기준을 분석하여 안전사고 예방 기법에 적용하고자 제시하고자하며, 향후에 이를 바탕으로 산업안전보건법상의 안전기준을 체계적으로 분석하여 제시하고자 한다.

We have endured a lot of social and economic loss due to the industrial calamities. A study for the government policies to reduce the loss in the field of industrial safety and health leaves much to be desired. The practical one on the government policies industrial safety and health policies, however, hasn't been accomplished as much expected. The purpose of this study is to suggest a research framework fir the execution process analysis, which is needed to find out the desirable or undesirable elements of industrial safety and health policies. The focus of the analysis lays on a policy problem of the industrial safety and health criteria. And based on this paper, it will proceed to the practical research for the industrial safety and health policies.

산업재해로 인한 개인·사회·국가적 손실이 막대함에도 불구하고, 이러한 산업재해손실을 최소화하기 위한 산업안전보건정책의 결정과 집행과정에 대한 분석·연구는 매우 미흡한 실정이며, 유사한 성격의 사회정책으로서 공정거래제도나 환경분야보다도 훨씬 뒤떨어 져 있다 본 논문은 산업안전보건기준이라는 정책과제를 중심으로 산업안전보건정책의 집행 과정의 성공과 실패요인의 분석에 필요한 연구분석들을 제시하고자 하며, 향후에 이를 바탕으로 실증적인 적용실태연구를 통해 산업안전보건정책방향의 일단을 제시하고자 한다.

일정 규모 이상의 사장교와 현수교에는 자유장, 주탑, 보강거더에 지진가속도계가 부착되어 있다. 이 연구에서는 부착된 센서를 활용하여 지진발생 시에 긴급하게 지진안전성을 평가하는 방법을 제안하였다. 표준화된 시스템으로 긴급한 평가가 이루어지므로 센서 단위의 평가가 효과적이며, 경주, 포항지진에 대한 특수교량의 데이터 분석을 통하여 평가 방안을 도출하였다. 자유장, 교각기초, 앵커리지와 같이 지반 또는 지반과 인접한 위치에 설치된 가속도계는 최대가속도로 평가를 수행하고 주탑상부, 보강거더 등 구조물에 부착된 가속도계는 가속도의 변환을 통한 변위비교로 평가를 수행하는 것을 제안하였다.

This study examined the safety and reliability of code equations for the bond strength of FRP bars with concrete using test data compiled from the different sources. ACI equations have a better agreement with test results, whereas high overestimation is observed in JSCE equations.

In this study, quartile control chart method is tried to apply to determine limit values of existing dams of K-water’s instrumentation data for dam safety, show asymmetric distributed data, and the example of application is presented. The determined limit values of concrete stress meter and concrete non-stress meter by Shewhart method and quartile method show that the determined limit values by Shewhart method indicate that the majority of instrumentation are on abnormal condition, although the measured values are normal behavior. But, in case of the result of quartile method has such an error. Like this, it is judged that the determination of the limit values of dam instrumentation, show asymmetric and abnormal distributed data, by the quartile method is appropriate. Therefor The quartile method is applied to the determination of limit values of existing dam instrumentation of K-water.

In this study, hydrological safety vulnerability assessment on dam facilities was estimated using dams' hydrological safety evaluation result and in-depth inspection assessment score and grade. Multi Criteria Decision Making was used for vulnerability ranking decision on dams', and assessment scores and weights of hydrological safety evaluation were applied as payoff matrix and weight coefficient. It can be available for calculating dam’s vulnerability ranking considered dams' hydrological safety.

Recently, Korea Bridge Design Code(limit state design method) was introduced in 2012.However, Korea Infrastructure’s Safety Inspection Guideline are still following the bridge safety assessment. The assessment methods are classified according to material and bridge superstructure. Steel box girder bridge safety assessment was carried out by the A.S.D. In this study, introduce of steel box girder bridge safety assessment in accordance with the standards change.

Recently, Korea Bridge Design Code(KBDC) adapts to the Limit State Design method(L.S.D) in 2012 according to the liberalization of construction market and the flow of international standardization of the design criteria. However, Korea Infrastructure’s Safety Inspection Guideline(KISIG) are still following the bridge safety evaluation applying the A.S.D and U.S.D methods. In this study, introduction of PSC bridge safety evaluation with L.S.D considered the traditional safety evaluation compared to the ASD and USD methods.

According to the available date sources, 1,814 bridges failures occurred over the past 210 years in the United States. The most frequent cause of bridges failures were attributed to external events such as: floods, collisions, scour, overloading and deterioration. Among these external events, Hydraulic factor caused the maximum number of bridges failures with 54% of the total failures. 20% of hydraulic factor was failed by scour. Thus, base on the result of reviewing design basis and safety assessment practices, criteria for determining safety assessment of bridge foundation scour is proposed. 25 bridges were reviewed for applicability to scour safety assessment of passing bridges in river channels.

최근 공동주택 구조형식이 벽식 구조에서 리모델링이 자유로운 기둥식 구조로 변화고 있으며, 이에 따라 경량벽체의 활용이 점차 늘어나고 있다. 공동주택에 사용이 증가하는 경량벽체는 소비자의 다양한 요구수준에 부합하여야 하나, 국내에서는 경량벽체에 대한 요구 성능별 성능기준이 미비한 실정이다. 국내 현실상 주거문화에서 공동주택이 차지하는 비율이 매우 높은 상황과 공동주택 건설 양식이 기둥식 구조로 전환되는 시점에서 사용이 점차 증가하고 있는 경량벽체의 성능등급 설정은, 향후 더욱 다양해지는 소비자 요구수준의 만족, 화재로부터 안전한 삶을 영위하기 위하여 세대내 벽체의 화재안전성능에 대한 기준을 제시하고 이를 평가하여 소비자가 선택할 수 있게 한다면, 국내 주거환경의 질은 높아질 것으로 사료된다. 본 연구에서는 공동주택 세대내 벽체의 화재안전 성능등급은 총 3개 등급으로 설정하고 30분의 내화성능 또는 총방출열량, 화염전파성능, 열방출률지수를 평가하는 연소성능 기준을 제시하였다. 그리고, 경량벽체 품목중 일반적인 구조에 대한 내화성능 평가 결과 석고보드 칸막이벽은 최소 30분 이상의 내화성능을 만족하였으며, 연소성능은 석고보드 간막이벽과 ALC 벽체 모두 1등급의 성능을 만족하는 것으로 나타났으며, 성능평가를 수행한 4개 구조 모두 실제 건설현장에서 일반적으로 사용되는 세대 내 벽체 구조로서, 모두 1등급의 성능을 만족하는 것으로 나타나 건설 현장에서 제시된 성능기준을 적용하는데 문제가 없을 것으로 사료된다.

In this study, the validity of the current vehicle axle load restrictions, enforcement, and permit criteria established for the safety of the road structure were investigated. improvement of the current criteria based on the results of the review were proposed.

HACCP methodology was applied in the post-harvest processing and storage of domestic medicinal produces. Particularly in terms of mold and mycotoxin contamination, candidate critical control points (CCP) in the conventional practice in Korean farms were selected and monitored by comparing with on the standard guided processing and storage. When each processing of Angelicae Gigantis Radix were assessed for their safety, the drying steps such as the sun drying or the thermal drying depending on each farm made differences in mold contamination. Moreover, the storage conditions before or after the processing were another critical determinant in the fungal contamination. In other words, storage under 4˚C rather than at room temperature was favorable for reducing mold growth in the harvested crops. Occurrence rate of Aflatoxin B1 (AFB1) in Angelicae Gigantis Radix were 12.8%, but amount of AFB1 in all the collected samples were below 10 ppb regulatory limit allowed in Korea. However, for a few samples of Angelicae Gigantis Radix, still relatively high levels of total amount of the major aflatoxins (aflatoxin B1 + B2 + G1 + G2) were observed around 0.18~49.94 ppb, which is not regulated presently in Korea. It thus can be suggested that post-harvest processing and storage of Korean medicinal crops need further investigation and monitoring to establish the Good Agricultural Practice (GAP), particularly to minimize microbial risk including mold and mycotoxin contamination under the changing climate. Additionally, it is also warranted for new enacting of regulatory limits for total aflatoxins in the medicinal crops.
