In general, Reinforced Slopes by Shotcrete are difficult to inspect because of stiff Slope and highly Working Area. So the Inspection Techniques are needed by the Non-contact and Non-destructive. On this Study, Appling the safety method to finding the weak zones(cavity area, dampness area, etc.) by using the Infrared Thermal Technique That is detecting the Detail Thermal Difference on the Surface of Reinforced Slopes by Shotcrete.

최근 용지보상이나 환경문제 및 도로선형 등으로 인해 도로건설 중 터널구간이 늘어나고 있으며, 이로 인해 터널시공 중 크고 작은 붕괴 및 이에 대한 보강이 빈번히 발생하고 있다. 대부분의 터널이 지표하 수십 m에서 깊게는 100m 이상에서 건설되고 있어 지표에서 붕괴의 원인 및 보강결과에 대한 확인이 결코 쉽지만은 않은 상황이다. 본 사례에서는 지표하 약 130m에 위치한 터널붕락 구간에 대하여 터널내에서 비파괴검사인 3차원 전기비저항탐사를 실시하여 보강결과를 확인하였다.

Motion generation of a four-bar linkage is a type of mechanism synthesis that has a wide range of applications such as a pick-and-place operation in manufacturing. In this research, the use of meta-heuristics for motion generation of a four-bar linkage is demonstrated. Three problems of motion generation were posed as a constrained optimization probably using the weighted sum technique to handle two types of tracking errors. A simple penalty function technique was used to deal with design constraints while three meta-heuristics including differential evolution (DE), self-adaptive differential evolution (JADE) and teaching learning based optimization (TLBO) were employed to solve the problems. Comparative results and the effect of the constraint handling technique are illustrated and discussed.

After participation in the Colombo Plan in 1954, Japan has provided Official Development Assistance (ODA) to 185 countries and areas, and the accumulated amount of Japan's ODA is approximately US$ 221 billion for 50 years. Japan is the second largest ODA donor country in the world now. The country is contributing to the peace and development of the international community. However, the recipient government and the parties concerned are not always satisfied with the Japan's ODA system.. Especially the grant aid system is strongly based on the domestic public work system. This paper analyzes the problems and figures out solutions from the viewpoint of donor and the participant.

The Republic of Korea developed a national project to construct a new administrative capital, Sejong city and to relocate administrative organizations of the central government for improvement of overpopulated capital, Seoul and regional balanced development. By the way, to relocate the central administrative organizations was not a sufficient condition for the sustainable development of the city. An industrial infrastructure development has been tried to attract universities, enterprises and research institutions in the region as a demand for internal growth power of the city was increased. In addtion, a basis for regional endogenous growth through projects to establish innovation system based on industry-academia cooperation was prepared as well. This paper reviews the major contents of the development plans for Tech-Valley project and looks into major introductory functions, characterization plans, strategies for fostering strategic industry, cooperation system of the inside and outside the region, and a strategy for building innovation platform. This case can be regarded as a significance of constructing technology infrastructure for the sustainable growth by preparing foundation for establishing innovation system and a cluster based on this system in the process of building and developing new city which did not have any industrial platform in the region.

The purpose of this dissertation is to build a development density control model and estimate optimum developmental density level for a sustainable urban growth management. To develop the model, system dynamics modeling approach was used. The model was developed to analyze how urban growth, transition, and decay occur depending on the interaction among population, houses, industry structure, land and urban infrastructure such as road, water supply, and sewage treatment facilities. The model was applied to Anyang city to estimate optimum density level. Extensive computer simulation was conducted to find out the maximum numbers of population, industry structure, houses, and cars that can be adequately sustained with the current Anyang city's infrastructure capacity. The computer simulation result shows that the city is overpopulated by some 90,000 people. It nab analyzed that 20％ increase of existing capacity of urban infrastructure is necessary to support current population of Anyang city. To reduce the population to the adequate level whereby the current urban infrastructure can sustain, the current city regulation on floor area ratio needs be strengthened at least 20％ to 35%.

The purpose of this paper is to examine the impact of consumer price index, infrastructure, human resources, trade openness, and private credit on the attraction of foreign direct investment (FDI) in Tay Ninh province as well as to emphasize the important role of FDI in economic growth of developing areas. The research data was collected from Tay Ninh Statistical Office with 80 samples of a 20-year period from 2000 to 2019. Also, OLS regression method using Eviews software was employed to analyze the data obtained. The findings revealed that human resources, infrastructure and private credit have a positive and significant impact on FDI attraction in Tay Ninh province, while consumer price index was proven to affect FDI attraction negatively. Accordingly, competent authorities of Tay Ninh province should focus on stabilizing prices as well as implementing policies for developing local human resources and attracting high-quality personnel from foreign countries. Tay Ninh province also needs to pay more attention to information technology investment for synchronous development of infrastructure. Moreover, the State Bank of Tay Ninh branch needs to consider more credit sources to provide support packages for businesses, creating a strong basis for establishments to attract FDI for the province's economic development.

The advanced infrastructure for accelerating the development of personal robots is presented. Based on this structure, effective ways for integrating the various commercial components and interfacing among them are studied. The infrastructure includes the technology such as modularization based on independent processing and standardization open to other developers. The infrastructure supports not only that each hardware component of a personal robot can be easily attached to and detached from the whole system mechanically but also that each software of the components can be functionally distributed. As a result, we developed the fully modularized personal robots mechanically, and a virtual machine for the control of these robots. In this paper the proposed infrastructure and its implementations are described.

Since the industrial revolution in 19 century, there had been a pro and con argument on which is better solution between privatization and nationalization in developing the infrastructure projects and in maintaining the infrastructure facilities worldwide. This paper introduces the privatization-nationalization wheel along with its advantage and disadvantage. At this stage according to the global trend, it is the time that the most of infrastructure projects are being developed by the private sector in the industrialized countries. It is mainly because the product or the services produced by the facilities of the infrastructure should be fully paid back by the end users according to the mechanism of the market economy. Some solutions have been suggested for the future development of infrastructure projects in S-N Korea.

This article studied French case, German case, and England case of rail reform in terms of the relationship between rail infrastructure operator and train operator. Among these three cases there are tie relationship between two different operators backed up by laws. In France the relation between RFF, infrastructure operator, and SNCF, train operator is set up by laws. In Germany the infrastructure operator and train operator form a Konzern and two different operators work with close cooperation. In England SRA, a government authority, plans both infrastructure development and rolling stock demand. From these case studies a conclusion results that there should be a institutional device to maintain close relationship between infrastructure operator and train operator.
