Tankers have somewhat different shapes in construction and working condition compared with normal merchant ship. If an accident occurs, normal merchant ship's damages will mostly be confined to ship and cargo, but those of tankers will result in oil spills and catastrophic loss beyond our imagination. So, first we must understand risk factors, pre-loss control and post-loss control, legal regulations about its indemnification and marine insurance for oil tanker operation. When unexpected accidents happen, despite pre-loss control, it is possible to cover those kinds of losses by insurance. To control these losses, however, it is important to establish compensation for oil pollution and arrange for oil pollution preventing system. In spite of these oil pollution preventing systems, we have rarely seen that pollution from oil tankers could be solved. So this paper was studied more fundamental and overall control measures for the risk management of oil tanker operation.

공동구는 도시생활을 영위하는 데 필요한 전기, 가스, 상 하수도, 전화, 통신 등의 공공시설물을 지하매설물 형태로 설치하여 시민들의 일상생활 및 사회 경제활동의 편의성을 제공하고 안전하고 안락한 도시환경을 유지시키며, 효율적인 도시운영이 가능케 하는 공공시설물이다. 그러나, 최근 들어 여의도 공동구 화재(2000년), 여수 공동구 침수(2003년), 구리시 전력구 화재(2006)등과 같이 공동구 및 전력구에서의 화재, 혹은 침수 등에 의해 재해가 발생하여 이로 인한 국가적 경제적, 사회적 손실이 늘어가고 있다. 하지만 국내에서는 공동구내 설비를 화재 및 재해로부터 보호하기 위한 법적 장치가 미비한 실정이며, 현재 운영되고 있는 공동구의 관리 또한 시설관리공단이나 위탁관리기관 등으로 분산되어 있어 일정한 시설물 설치기준이나 유지관리제도가 정립되지 못하여 효율적인 운영이 이루어지지 않다고 판단된다. 본 연구에서는 근래 국내에서 발생한 공동구 재해사례와 공동구 관련 법규를 검토 분석하였으며, 다양화되어 가는 공동구 수용시설 조건에 부합하고 체계적이고 효율적인 공동구의 시공을 위한 공동구 건설기준 제정방안을 도출하였다.

The number of cyclists is on the steady growing for leisure, sports and transportation with the increasing interest in health and environment. However, the number of cycling accidents is also increasing steadily due to the lack of safety awareness and regulations. Focusing on these issues, we propose and develop the smart LED cycling helmet in order to reduce a risk of cycling accident. To provide the motion information of the bicycle for others, we attach the LEDs on the helmet and control the LED lights using Arduino. The motion information is displayed on the LED helmet by using sensors of the smartphone. Communication between Arduino and the smartphone is performed through Bluetooth.

Attempts were made to increase an efficiency of soil contamination investigation systems(SCISs) including Soil Contamination Fact-Finding Investigation Sites and Special Soil Contamination Management Facility Sites in Korea. In order to increase low efficiencies resulting from inappropriate SCISs, possible policy suggestions are driven based on the results from problem findings of Korean policy and comparisons of policies in industrialized countries including United States, United Kingdom, Germany, the Netherlands and Japan. First, functions of Soil Environment Conservation Act(SECA) on liability should be updated and reinforced to initiate a soil contamination investigation process for stakeholders including an owner(s) or a responsible party(ies) of the potentially soil contamination sites positively. Second, appropriate SCISs should be emerged for implementing the Soil Contamination Fact-Finding Investigation Sites and Special Soil Contamination Management Facility Sites properly. Stakeholders for the potentially contaminated sites should easily access and raise the soil contamination issues, and soil contamination investigation implemented by liable and profit environment (consulting) companies should be encouraged. Third, the soil contamination reporting system of SECA needs to change legally responsible. Further more, public announcement system showing soil quality of a site which exceeds a certain scale would be considerable. Fourth, liable environment (consulting) companies should legally execute Soil Environment Assessment of SECA.

A plant layout problem has a large impact on the overall construction cost of a plant. When determining a plant layout, various constraints associating with safety, environment, sufficient maintenance area, passages for workers, etc have to be considered together. In general plant layout problems, the main goal is to minimize the length of piping connecting equipments as satisfying various constraints. Since the process may suffer from the heat and friction loss, the piping length between equipments should be shorter. This problem can be represented by the mathematical formulation and the optimal solutions can be investigated by an optimization solver. General researches have overlooked many constraints such as maintenance spaces and safety distances between equipments. And, previous researches have tested benchmark processes. What the lack of general researches is that there is no realistic comparison. In this study, the plant layout of a real industrial C3MR (Propane precooling Mixed Refrigerant) process is studied. A MILP (Mixed Integer Linear Programming) including various constraints is developed. To avoid the violation of constraints, penalty functions are introduced. However, conventional optimization solvers handling the derivatives of an objective functions can not solve this problem due to the complexities of equations. Therefore, the PSO (Particle Swarm Optimization), which investigate an optimal solutions without differential equations, is selected to solve this problem. The results show that a proposed method contributes to saving the capital expenditures.

In order to develop technology for an equipment qualification (EQ) test, which is an important process in localizing solenoid-operated valves used in nuclear power plants, we analyzed related regulations, test procedures, conditions, equipment, and acceptance criteria. EQ regulations for the solenoid-operated valve are classified as law, guide, and standard, and are subdivided according to test specimens and contents. The EQ test is composed of functional, normal-, and accident- condition tests. The solenoid-operated valve is aged under normal and accident conditions, which are predicted in the design conditions of a nuclear power plant, and the performance of the valve is measured by a functional test. The test method and procedure analyzed in this paper might be very useful for manufacturers as well as EQ testers.

As many countries have been raising awareness of environmental issues, greater efforts for eco-friendly construction have been made in both governmental and private sectors. However, assessment circumstances for building energy performance and green building standard of legislation are still based on two dimension and handwork. This takes time, cost and labor, and makes assessment inaccurate and inefficient. Therefore, this study suggests methods to improve eco-friendly construction permission process and to automatize open BIM-based assessment of Energy Performance Index (EPI) among several eco-friendly construction certification standards. First, it analyzes the relations between assessment criteria and IFC data, and provides solutions to problems and limitations. Second, it applies the solutions to assessment program in order to automatize open BIM-based assessment for EPI. The eco-friendly construction permission process with these solutions applied will reduce time, cost, and labor by simplifying and automatizing the tasks. Also, the simplified process of design revision will improve not only productivity and efficiency but also accuracy and reliability.
