Public infrastructure is crucial to promote and sustain a sustainable economic growth and a health community. A large amount of capital investment is generally required in infrastructure projects that motivate the involvement of the private sector in the delivery process. Various relationship-based procurement methods have been attempted to maximize value-for-money. In this paper, the problems and challenges that relationship-based procurement methods have been facing are explored. A particular focus is placed on the challenges for the public-private partnership (PPP) model. Possible strategies for adapting the PPP models in the post-Global Financial Crisis era are proposed and discussed. In addition, the challenges facing alliancing, which is one of the other important relationship-based procurement methods, are also examined. Views on infrastructure procurement in the future were sought from industry professionals via interviews and are reported in this paper as well.

With rapid growing of the Northeastern Asia, the interest for the connection of Infrastructure that was behind of interesting until now is getting larger. In a line of same connection, UN-ESCAP are forwarding transcontinental railway project, asian highway project et al.. And this study aimed at analysis on the effect that extended to a space by Korea-Japan undersea tunnel project. In aspect of a national land balanced-development to solve various problems such as overcrowding in capital region, unbalanced state by regions, weak exchange between South and North Korea, and weakness of national land basis to prepare for unification et al., this study consulted the economic potentiality model as a analysis method to examine an effect. In this analysis, I used 24 scenarios including all cases by combination of 3 scenarios for Korea-Japan undersea tunnel, 4 scenarios for transportation modes in the section of undersea tunnel, and 2 scenarios for adjacency infrastructure. Transportation modes in the section of undersea tunnel are railway, car-train, mixing way of railway and car-train, and mixing way of road and railway. Adjacency infrastructure applied railway and road. In all scenarios, Korea showed higher growth potentiality than Japan. Also, proposal plan C route relatively showed better in national land balanced-development than other proposal plans. The growth potentiality relatively appeared higher by buildup of a connection together with non-capital regions from the construction of Korea-Japan undersea tunnel. In aspect of Northeastern Asia, it resulted in a increasing of trade and chance of network formation in the region of Asia through infrastructure connection. But, in considering passenger and various factors that extended to the economic growth, this analysis have some limitation. Therefore, I hope that deep studies will continuously perform with various factors.

The femto fusion technology refers to not only the technology for femtosecond($10^{-15}$ second) laser and but also the fusion technology of its application. This technology is comparable to the nano technology, the extreme technology on the space, and is of extreme time-domain technology. Now, we need to develop the hyperfine and high-precision femto fusion process technology which allows to miniaturize and highly integrate the products of mobile, semiconductor and display industries, the national main focusing growth industries. However, The femtosecond laser fabrication technology is essential in the development of fusion technology, but only a few of domestic researchers can handle the former. Under this condition, our government plans to develop the "femto fusion technology infrastructure project" as one of the ICT research infrastructure. So the purpose of this study is to analyze the feasibility of this project. We applied AHP(analytic hierarchy process) for this study. The final result shows that all the repondent's score is over 0.55 and the aggregated score is 0.846. And as a consequence, we can conclude that to do this project is feasible.

This study investigates the decision criteria used in the context of IT investment decision making and empirically analyzes the impact of IT project size and types on the importance of decision criteria. 5 criteria which have been extracted from the previous studies and industry practices are budget, financial benefits. strategic value. risk, and the degree of proposer's eagerness. Data of 120 IT project proposals have been collected from 5 companies including bank, insurance. and stock trading company. As results of ANOVA test. 7 out of 10 hypothesis have been accepted statistically. That is. the bigger the project size. the higher the evaluation weight of project budget and risk criteria and the lower the weight of proposer's eagerness. And in case of the infrastructure investment type. the emphasis is placed more on strategic value and risk criteria and less on financial benefit and proposer's eagerness. These findings provide insights for both IT practitioners and researchers.

Otemachi(大手町) is the region where it plays a pivotal role in Japanese economy as representative head offices of companies including financial insurance, general trading, information and communication newspaper media are concentrated. However, regenerating the entire region from worn-out infrastructures of buildings and city into the fresh and vibrant foothold in international business was the problem to be solved. In this situation, was examined on the basis of administrative agencies and relevant enterprises to reconstruct office buildings in phases without ceasing business functions and activities by utilizing the large-scale vacant land occurred from the relocation of the national public institutions. The independent administrative institution 'Urban Renaissance Agency(UR)' has completed the examination of industrialization and participation request for the commencement of the project. In this article, The overview of , the new form of project promoted and cooperated by officials and people, is introduced by UR (Urban Renaissance Agency) reorganizing the land exchange and infrastructure through the land readjustment project, and at the same time, procuring capital and building office buildings in solidarity with private development enterprises and financial institutions.

Due to the development of modern technology and the enlargement of industrial scale, the scale of many projects is expanding and the complexity is also increasing. Individual management of existing projects cannot effectively manage projects in this trend, and it is necessary to systematically manage the entire process from initiation to completion. Accordingly, the need for integrated management and life cycle management that can efficiently manage the entire project is emerging, and for this, a systematic project management system is also required. PMS enables efficient project management by linking business processes such as resource, schedule, scope, and output management of a project with separately separated infrastructure accordingly. In this paper, a research model was proposed to manage the project from the perspective of implementing integrated management and life cycle management, especially during R&D project execution, and to prove the mediating role between PMS and R&D project performance for this purpose. The proposed research model will be able to help companies and organizations that feel the need to implement integrated management and life cycle management and are preparing to build a PMS-type system or that have already been established to efficiently perform project management.
