Solar radiation induces non-uniform temperature distribution in the bridge structure depending on the shape of the structure and shadows cast on it. Especially in the case of curved steel box girder bridges, non-uniform temperature distribution caused by solar radiation may lead to unusual load effects enough to damage the support or even topple the whole curved bridge structure if not designed properly. At present, it is very difficult to design bridges in relation to solar radiation because it is not known exactly how varying temperature distribution affects bridges; at least not specific enough for adoption in design. Standard regulations related to this matter are likewise not complete. In this study, the thermal behavior of curved steel box girder bridges is analyzed while taking the solar radiation effect into consideration. For the analysis, a method of predicting the 3-dimensional temperature distribution of curved bridges was developed. It uses a theoretical solar radiation energy equation together with a commercial FEM program. The behavior of the curved steel box girder bridges was examined using the developed method, while taking into consideration the diverse range of bridge azimuth angles and radii. This study also provides reference data for the thermal design of curved steel box girder bridges under solar radiation, which can be used to develop design guidelines.

Capacity design is to guarantee ductile failure of whole bridge system by preventing brittle failure of columns and any other structural elements until the columns develope fully enough plastic deformation capacity. This concept has been explicitly regulated in most bridge design specifications of foreign countries except the current Korea Bridge Design Specifications. In the capacity design, the transformed shear force from flexural overstrength of reinforced concrete column is used as the design lateral shear force for shear design of columns and design of footings and piles. Different calculating methods are adopted by the design specifications, since the variability of material strength and construction circumstances of the local regions should be considered. This paper proposed material overstrength factors by investigating 3,407 reinforcing bar data and 5,405 concrete compressive strength data collected in Korean construction sites. It also proposed calculating procedures for flexural overstrength of reinforced concrete columns using the material overstrength. Finally, overstrength factor was proposed as 1.5 by investigating 1,500 column section data from moment-curvature analysis using the material overstrength.

본 연구는 미국과 유럽의 채권 전자거래에 대한 제도를 분석한 후, 우리나라의 채권 전자거래에 대해 시사점을 제시하고자 한다. 본 연구의 결과는 다음과 같이 요약된다. 첫째, 미국과 유럽에선 채권 전자거래 시스템(Electronic Trading System, 이하 ETS)의 영업행위가 원칙적으로 증권 중개업의 관점에서 규제된다. 이러한 방향의 규제 체계는 다양한 형태의 채권 ETS가 등장할 수 있도록 하여 채권시장의 발전에 기여한다. 둘째, 우리나라의 $\ulcorner$한국증권선물거래소법$\lrcorner$ 15조 2항 및 $\ulcorner$증권거래법시행령$\lrcorner$ 84조의27 6항은 다양한 형태의 채권 ETS의 등장을 원천적으로 봉쇄함으로써 채권시장의 발전을 저해하고 있다. 셋째, 현행 $\ulcorner$한국증권선물거래소법$\lrcorner$ 15조 2항은 주식 및 선물거래에 대해서 계속 적용하되 채권거래에 대해서는 그 적용이 유보될 필요가 있다. 이를 통하여 $\ulcorner$한국증권선물거래소법$\lrcorner$은 주식시장을 활성화 시키는 순기능을 유지하면서 채권 ETS의 등장을 원천적으로 봉쇄하는 역기능을 피할 수 있다. 넷째, $\ulcorner$한국증권선물거래소법$\lrcorner$ 15조 2항이 채권거래에 대해서 적용되지 않는다면, $\ulcorner$증권거래법시행령$\lrcorner$ 84조의27 6항은 삭제되어야 하며, 대신에 증권거래법은 채권 ETS의 활동 범위와 요건을 정의해 주어야 한다. 채권 ETS의 활동은 원칙적으로 증권업자의 중개활동으로 간주되어야 한다. 채권 ETS의 중개 규모가 일정 수준을 넘어설 경우 거래소에 준하는 보고, 공시 및 감시 요건이 부과되는 것이 바람직하다. 다섯째, 채권시장의 효율성을 강화하기 위해서 채권 ETS에 대해서 적용되는 투명성 강화, 시장분할 방지, 공정거래 등에 대한 규제는 거래 대상의 특성에 따라서 탄력적으로 조정될 수 있어야 한다.

The object of this research is to develop a computerized algorithm of cost estimation method to forecast the total construction cost in the bidding stage by the historical and elemental work cost data. Traditional cost models to prepare Bill of Quantities in the korea construction industry since 1970 are not helpful to forecast the project total cost in the bidding stage because the BOQ is always constant data according to the design factors of a particular project. On the contrary, statistical models can provide cost quicker and more reliable than traditional ones if the collected cost data are sufficient enough to analyze the trends of the variables. The estimation system considers non-deterministic methods which referred to as the 'Monte Carlo simulation. The method interprets cost data to generate a probabilistic distribution for total costs from the deficient elemental experience cost distribution.

As the law on the private sector investment in social infrastructure was amended in January of 2005, the government is aggressively promoting BTL projects but many trials and errors and problems are occurring. Especially, the Value-For-Money evaluation conducted by the responsible agencies to judge the appropriateness of the project found there was a conspicuous difference between the computed cost and the final contract sum. Accordingly, this study is aimed to grasp the problems in the current Value-For-Money evaluation and to improve it in order to proceed with BTL projects efficiently. To achieve this, through a relative comparison to the final contract sum, a clear standard for the items of Value-For-Money evaluation was presented and thus, a model that can ensure accuracy in computing the Value-For-Money was established so that a delay in negotiations can be avoided. If the Value-For-Money evaluation established in this study is used in assessing the appropriateness of unit prices for BTL projects for education facilities, a reasonable result can be expected to be drawn in selection and negotiations with contractors, and maintenance and Post-Operation-Evaluation(POE) of education facilities as well.

The trust issue on the safety of autonomous vehicle is a very important in regard to the demand generation of relevant industries. To secure the trust, The study of legal liability issue should be prior to an accident of the autonomous vehicle. In civil law, it is possible to make the automobile manufacturer take legal responsibility with the "Product Liability Act". Whereas, in criminal law, it is difficult to make him take legal responsibility since the criminal law holds the actor responsible. To solve these problems, this article proposes the establishment of the "Special Act on Autonomous Vehicle". Also, there is a demand for building infra structures and system to operate the (fully) self-propelled vehicle and establishing "certification" systems.

As a method of providing lifelong educational opportunities to working professionals, some legal provisions allowing for the establishment and management of an entrusted education system linked with college and corporation was duly approved in 1994. According to the recent trend in the military organization, to provide higher educational opportunities to noncommissioned officers and warrant officers with the purpose of inspiring their spirit and improving military capabilities has been much increased. Professional soldiers such as noncommissioned officers and warrant officers have a lot of problems to continue their attendance at school because of regular military maneuvers, constant alert status and long-term outdoor military training. Even more serious problem is that the current curriculums and some departments in college are not concurrent with the present job specifications and the military specialties of the individual soldier as well. The purpose of this paper is, therefore, to introduce a newly revised educational model that provides more viable academic courses and curriculums to military professionals along with a proposal for the establishment and management of long distance educational system within barracks, utilizing the latest information and telecommunication technology.
