본 연구에서는 도로법과 건설기술진흥법을 근간으로 하는 두 가지 기준체계를 가지고 있는 우리나라의 도로분야 건설 기준에 대해 조사하고, 이를 통합하여 체계적이고, 합리적으로 관리하기 위한 방안으로, 도로법에서 직접 위임하고 있는 도로의 구조ㆍ시설 기준에 관한 규칙에서 원칙과 기본사항을 정의하고, 계획, 설계, 시공 등 단계별로 요구되는 기술적인 사항은 건설기술진흥법에서 정하는 건설기준에서 정하고, 이를 적용하기 위한 대한 세부사항과 필요한 해설 등은 표준 도, 지침, 편람, 기술지도서, 업무요령 등 국토교통부 훈령인 건설기술진흥업무 운영규정에서 정하는 하위기술기준에서 정하도록 하는 체계를 제안하였다. 이를 위해, 현장에서 실효적인 기준처럼 활용되고 있으나, 건설기준 및 하위기술기준 들과 중복적인 위치를 가지며, 법적 근거 없이 국토교통부 일반 간행물로 발간되고 있는 도로의 구조ㆍ시설 기준에 관한 규칙 해설을 국토교통부 발간물에서 제외하고, 주요 내용을 건설기준과 하위기술기준에 통합하고 폐지 또는 민간 발간물 로 변경하는 방안을 제시하였다. 이를 통해 현장에서의 건설기준 활용도를 제고하고, 하위기술기준들과의 적용에서 사용 자 혼동을 방지할 수 있을 것으로 기대된다. 또한, 본 연구를 통해 제안하는 기준 체계상의 기준은 최소한 건설기준위원 회의 검토를 통해 제정 및 개정할 수 있도록 하는 근거를 마련하여 위계별 기준들의 체계적인 연계와 역할분담을 통해 국가 건설기준 체계를 보다 합리적으로 관리할 수 있을 것으로 기대한다.

Deep geological disposal (DGD) of spent nuclear fuels (SNF) at 500 m–1 km depth has been the mainly researched as SNF disposal method, but with the recent drilling technology development, interest in deep borehole disposal (DBD) at 5 km depth is increasing. In DBD, up to 40SNF canisters are disposed of in a borehole with a diameter of about 50 cm, and SNF is disposed of at a depth of 2–5 km underground. DBD has the advantage of minimizing the disposal area and safely isolating highlevel waste from the ecosystem. Recently, due to an increasing necessity of developing an efficient alternative disposal system compared to DGD domestically, technological development for DBD has begun. In this paper, the research status of canister operation technology and plans for DBD demonstration tests, which subjects are being studied in the project of developing a safety-enhancing high-efficiency disposal system, are introduced. The canister operation technology for DBD can be divided into connection device development and operation technology. The developing connection device, emplacing and retrieving canisters in borehole, adopted the concept of a wedge thus making replacement equipment at the surface unnecessary. The new connection device has the advantage of being well applied with emplacement facilities only by simple mechanical operation. The technology of operating a connection device in DBD can be divided into drill pipe, coiled tubing, free-drop, and wireline. The drill pipe is a proven method in the oil industry, but requiring huge surface equipment. The coiled tubing method uses a flexible tube and shares disadvantages as the drill pipe. The free-drop is a convenient method of dropping canister into a borehole, but has a weakness in irretrievability in an accident. Finally, the wireline method can be operational on a small scale using hydraulic cranes, but the number of operated canisters at once is limited. The test facility through which the connection device is to be tested consists of dummy canister, borehole, lifting part, monitoring part, and connecting device. The canister weight is determined according to the emplacement operation unit. The lifting part will be composed following wireline consisting of a crane, a wire and a winding system. The monitoring part will consist of an external monitoring system for hoists and trolleys, and an internal monitoring system for the connection device’s location, pressure, and speed. In this project, a demonstration test will be conducted in a borehole with 1km depth, 10 cm diameter provided by KAERI to verify operation in the actual drilling environment after design improvement of the connecting device. If a problem is found through the demonstration test, the problem will be improved, and an improved connection device will be tested to an extended borehole with a 2 km depth, 40 cm diameter.

When the foundation work of the underground part of the building structure or the excavation work of the civil engineering structure is carried out, there is the earthwork work by the inevitable process. As the economic situation continues to develop, construction in urban areas is becoming bigger and higher in scale due to the expansion of infrastructure and the rescue of urban dwellings in urban areas, and excavation of underground roads is inevitable. Excavation of the underground part may cause problems in the process difficulty and safety of the earthworks due to the complexity and various characteristics of the ground selected without consideration of the ground characteristics and site conditions. In order to complete the required facilities, it is necessary to secure the design and construction of the retaining walls. In order to complete the required construction, It is an important factor satisfying construction period and economical efficiency.

공공계약의 기본법 역할을 하는 ｢국가계약법｣에는 공사, 물품, 용역에 대한 정의규정이 없어 공공발주기관의 자의적 판단에 따라 다수의 계약 제도가 불합리하게 운용되는 측면이 있다. 특히 ｢정보통신공사업법｣등 공사 관련 법령에서 정의하고 있는 공사의 경우 ｢국가계약법｣에 따른 공사 규정을 적용하여 입찰 및 계약 집행하여야 하나, 조달청 등 대부분의 공공발주기관은 계약목적물의 원가상 재료비와 노무비가 차지하는 비율을 따져 재료비가 노무비보다 많은 경우 전체 계약목적물을 물품으로 발주하는 관행을 보인다. 하지만 이러한 발주 관행을 뒷받침할 법적 근거는 없으며, 공사 관련 법령이 존재하는 한 계약목적물의 원가상 재료비와 노무비의 비율로 발주형태를 결정하는 것은 법적타당성이 인정될 수 없다. 이에 본 연구는 ｢정보통신공사업법｣상의 정보통신공사를 중심으로 ‘설치를 수반하는 계약목적물’이 ｢국가계약법｣상의 공사에 해당함에 관한 법적타당성을 밝히고, 물품으로 발주 시 문제점과 이를 해결하기 위한 개선방안을 제시하고자 한다.

오늘날 기성고 산정에 따른 완성공사비 대금지급의 산정에 대한 기준이 미흡하여 적정한 기성대금 산출이 이루어지지 않고 있어 분쟁이 많이 발생되고 있는 것이 현실이다. 선행논문은 기성고 해지비용, 건설 분쟁 예방 및 해결방안, 분쟁조정제도, 재판 외 분쟁해결방식 ADR(Alternation Dispute Resolution) 등으로 제도개선 이전에 단순한 여론조사 수준으로 시장분석을 기본으로 하는 연구가 진행되었다. 본 연구는 선행논문 검토와 문헌 조사, 전문가들의 실증적 분석, 본인 연구자의 실무 경험을 통해 국내ㆍ외 건설공사 기성고 산정에 대한 자료를 수집하고 분석하여 현행 건설공사 기성고 산정제도의 현황과 문제점을 검토하고 담론적ㆍ실증적으로 병행 분석하였다. 또한 실증적 분석에서 552명 중 33.10%가 내역서가 있는 경우 완성된 기성금액은 계약 수량에 완성된 수량을 곱하여 산정하는 것으로 조사되어 별도의 미완성공사비를 산정하지 않는 것으로 분석하였다.

Abstract It has come to attention that a risk-assessing organization, that will benchmark a company’s safety department, is imperative, following an increase in large-scale SOC-business project, construction of higher-raised buildings, development of underground space; all that have increase accident rates. Having faced problems that arise in firms that demand diversity, complexity and instantaneity, the purpose of the thesis is to arrive at efficient and practical problem-solving means. In order to solve the problems that would surface theoretically during an actual risk assessment, the state of the operation systems of the top five national construction firms having a hazard rate of 0.25 times less than the average rate have been analyzed, while a hierarchal recognition research of the employees who not only function at the operating level but are the practice subjects of a firm, has also been conducted, bringing the main text.

Domestic plant construction sites have a tendency to become bigger, more various and complicated. Moreover frequency of industrial incident is increasing due to short project period, coexistence work condition and using heavy construction equipment. Installing safety facilities and safety training contribute to prevent incident. But mostly incident happens due to workers’ unsafe action and wrong work method. Technically, it is very difficult for us to closely manage workers preventing incident. Therefore, the role of foreman who ordinarily works together with his workers is considered more important. Specific execution plan was drawn through industrial incident statistics from Ministry of Labor and questionnaire survey to interest parties(supervisor, safety staff and foreman). If foreman has raised sense of belonging and responsibility by conducting practical safety training for his workers, manages job site and receives proper compensation for these roles, it will be expected that it fully influences incident decrease.

The result of this paper will be well used as a basic data in establishing the manual necessary for executing the construction of skyscrapers more safely than the present where there is no specific direction for the safe management of skyscraper construction yet.

There is a considerable amount of research on ship worker’s hearing loss caused by vibration and noise that comes from the ship’s construction. A further investigation that characterizes the sound that comes from building or repairing a ship is nonexistent or insufficient, however. To do this, a noise management plan is needed. It should include a generated sound process from the main sources of disturbance in the ship- building areas. And a soundproof measurement will identify the amount of noise reduction needed for a hearing- safe working environment. Finally, researchers in this study measured tests on the noise and the vibration process, and the noise caused by operations allowed for an investigation on the suitability of certain environmental conditions. Noise-related programs can be used to predict the noise distribution of the noise level characteristic. This can help identify and reduce the presence of sound interference through sound proofing measures.

In rapidly changing circumstances, the construction industry shows tendency to be more complicated and expanded and these changes are becoming the main factors aggravating uncertainty in straightening construction costs in the industry. The most important process in preliminary phase is calculation of appropriate construction sum and accurate estimation is required to accomplish it. Currently, local constructors draw up estimates by using the ‘per square meter’ calculation method or by applying of previous cases as they are. These methods become suppressive cause for making clear decisions by occurring errors in quantity survey in a way of data emission, replication and so on. Therefore, in this study, approximate estimation model of finishing construction shall be proposed to assist people to make prompt decisions in initial design stage. To develop this research, the existing quoting practices shall be presented and categorized by usage of space. To achieve this, information on performance, furnishings and unit price according to space definition has been collected in advance, which again enable ontology knowledge classification scheming database of space unit to be utilized and presented as knowledge information.
