Underground infrastructure systems provide essential public services and goods through buried structures including water and sewer, gas and petroleum, power and communication pipelines. The majority of existing underground infrastructure systems was installed in green field areas prior to development of complex urban built environments. Currently, there is a global trend to escalate major demand for underground infrastructure system renewal and new installation while minimizing disruption and maintaining functions of existing superstructures. Therefore, Engineers and utility owners are rigorously seeking technologies that minimize environmental, social, and economic impact during the renewal and installation process. Trenchless technologies have proven to be socially less disruptive, more environmentally friendly, energy conservative and economically viable alternative methods. All of those benefits are adequate to enhance overall sustainability. This paper describes effective sustainable solutions using trenchless technologies. Sustainability is assessed by a comparison between conventional open cut and trenchless technology methods. Sustainability analysis is based on a broad perspective combining the three main aspects of sustainability: economic; environmental; and social. Economic includes construction cost, benefit, and social cost analysis. Environmental includes emission estimation and environmental quality impact study. Social includes various social impacts on an urban area. This paper summarizes sustainable trenchless technology solutions and presents a sustainable construction method selection process in a proposed framework to be used in urban underground infrastructure capital improvement projects.

For the problems in executing rural development, recent recognitions are that discovery, preservation, and utilization of area-unique resource are unsatisfactory, that participation of local residents was neglected, and that approach to gradual refurbishment of houses and common space of town in consideration of existing spatial pattern of the town was not adequate. Especially, neglect for exact investigation, analysis and evaluation on rural local resources is bringing about social problems such as mass production of uniform rural area and loss of local identity. In this study, rural resources were listed and resource evaluation items was designed in order to establish development direction of rural village. According to these results, for the efficient and reasonable drive of the resource evaluation system, following items are required; A premise of local development by participation of local people, Development of diversely appliable resource evaluation clauses, Establishment of development type in connection with resource evaluation clauses, Systematic management of local resource through spreading DB resource. This research was loused on unearthing direction development of rural village and theme. However, what should be reconsidered through continuous study is that resource evaluation clauses are somewhat general and not concretely illustrated. Therefore establishment of characterized development is expected through clarifying local identity and presenting direction of local development, with the importance of resource and systematic analysis in planning on rural village in the future.

The key challenges and problematic aspects of the formation of intellectually and innovation-oriented strategies of regional entities at the present stage of their development are considered. The main tasks that arise in the process of strategizing the potential-forming development of regional economic systems in the context of digitalization are identified. The list of key organizational and economic directions of strategic character of providing intellectual and innovative development of regional economic systems is formed, which includes clustering of centers of high-tech development of regions, creation of creative hubs, development of knowledge infrastructure and improvement of interregional cooperation; a brief description of each of the presented strategic organizational and economic directions is given. Based on the analysis, the key strategic guidelines for the development of regional economic entities in the context of digitalization under the influence of potential-forming determinants, which form the content basis for further processes of strategizing qualitative aspects of development of specific regional entities.

This paper briefly presents the AIS land infrastructure in Sweden and how it is used as a common resource by multiple users. Some of the applications for the AIS information within the Maritime Administration are presented. It also discuss international co-operation concerning AIS land infrastructure, exchange of AIS information and possible future development. Existing and expected problems with AIS are shown and mitigation measures presented.

This paper focuses on the Japannese policies on infrastructure investment. Generally such issue is considered with respect to the three points: the body who is in charge of the development, maintemance and ownership of a particular infrastructure: financial resources required for investment: and the amount of charge imposed on users. These points are closely related to each other, and are essential for the effective supply of infrastructure. Therefore, this paper reviews the case in Japan and get some insight for solving the problem faced by Korea.

This study was tried for the improvement of software process ability of the software firms, and analyzed empirically the impact that a software process infrastructure level influences on the software process level and process performance. The questionnaire were developed and data were collected from the process improvement correspondences or project quality managers of the 78 software firms. The result was shown that management-organization infrastructure was composed of software process improvement organization's role and activity, process standard and education, management system and supporting, management guides and procedures. And organization's standard development procedure or criteria, process asset, process support tools were included in technical infrastructure. This study provides that some components of software process infrastructure had an significant influence on the process level, process infrastructure management level, and software process performance.

As demands and interests in visiting rural village increases, government authorities are promoting eco and green tour village development project through plural functions of rural village. The purpose of this study is to understand infrastructure improvement direction by researching the case study of general rural villages' changing to eco and green tourism villages. As for the research method, the character of each village was verified, then the case studies of improvement by life infrastructure using the identity of villages were analyzed. Finally, it was found that infrastructure through public facilities improvement and environment improvement project was expanded and relaxative and experiential space was offered by creating tour infrastructure using the identity of villages. Also, it was shown that farming infrastructure creating project was executed to promote the income base of locals.

With due to the recent development of USN (Ubiquitous Sensor Network) technology, a monitoring system has been developing for assuring the structural integrity of infrastructure through normal or long term measurements during their lifetime. An accident such as a collapse of infrastructure may cause not only loss of life but also damage to the economy of the nation. In order to enhance the availability of infrastructure and to be able to maintain their lifetime, it is necessary to monitor and to evaluate continuously the structural integrity throughout their entire lifetime. The purpose of this paper is to develop a monitoring system integrated with evaluation function based on the ubiquitous technology. The most essential part of this study is focusing more on developing a specific module convertible to A/D, which is to enhance the applicability of sensors that had not been applied to existing monitoring systems. Conclusively it has been successfully enhanced to make more diverse the number of sensors and measuring techniques for the monitoring system.
