The rapid development and diversification of technology require that firms should adjust and cope with a high degree of uncertainty regarding independent efforts in technology development. An alternative to these strategic responses is the R&D or technological collaborations among firms. There have been many researches on the reasons for and effects of these collaborative relationships; however, research examining the risks involved in the process of collaboration is lacking. The researches into essential prerequisites for successful technological collaborations have remained more or less premature despite of the increasing demand for interfirm R&D collaborations. In other words, the existing literature has mainly focused on the choice of collaborations, but has paid little attention to the processes of collaborations. This study tries to identify and integrate both success and risk factors affecting the decision making of whether collaborations are attempted or not and R&D collaboration processes. Finally, a model of interfirm collaborations is suggested and also practical implications for the firms which consider R&D collaboration with other firms are provided.

The political and technological countermeasures to cope with the UR problems are under studying at present or some of them are already applied to increas farm household income. It is evident that the leisture farm development is considered the best alternative among the countermeasures. On account of mitigating labour shortage, a most difficult problem encountered by agriculture, and of promoting consumption of farm products, the leisure farm development could increase farm household incomes accoringly. This study is ultimately aimed at identifing the countermeasures to increase farm household incomes by suggestion of the improvement of leisure farm management thorough survey of the present leisure farm management status. The leisure farm. management survey was carried out based on the seven leisure farms such as Songnam, Cheongrock, Yusung, Duryong, Hwachun, Maesan and Sinhuck which are saperately located in Chungnam Province.

Nowadays, global warming and high oil prices were a threat to the survival of the whole human race. One of a solution to respond to these problems is to reduce energy consumption of building. By adopting energy-saving design, the dissemination of low energy building is required. Therefore, to improve energy efficiency while reducing the usage of the design method is necessary to study actively. BIM-based systems applied to buildings, scheduled to be built by reducing the amount of energy reduction technologies can be analyzed. Depending on various design and equipment to set energy savings goals, you can select an alternative. If it is possible to predict the energy efficiency from the initial stage of design and support designing low energy building, we would be able to expect improvement in the economics of housing due to the reduction of energy consumption.

The market for a payday advance, regarded as both a convenient and short term-loan for immediate financial help, has grown incredibly since the 1990's. Despite its popularity by borrowers and the possible benefits, it has received negative publicity. Some borrowers have been caught in a debt trap for a long-term period and at tripledigit interest rates. The objective of this study is to shed light on the borrowers' profiles and their demand for a payday advance. Based on the 2010 household level data from the U.S. Federal Reserve Board, this study finds that payday advance users are pronounced as seemingly risky people. Payday advance users tend to be college drop-outs, African Americans, and non-homeowners compared to non-payday advance users. They are more likely to overspend above their income and have a favorable attitude toward conspicuous spending than non-payday advance users. They tend not to shop at all nor perform even moderate shopping for credit before using a payday advance service as opposed to non-payday advance users.

The aim of this paper is to investigate how the public procurement policy exerts an effect upon the technology innovation of the firm and to make alternative proposals how to reinforce the effect. Although the pubic procurement process based on its monopsonic idiosyncrasy implies the means to lead the firms' supply function, the present system has contributed a little to accelerate the technology innovation. In fact, the system is lacking of the evaluation capability referring to the technological computer among the bidding films. So as to reinforce the function of technology innovation of the public procurement policy, it is necessary to improve the procurement institutions, in particular bidding and contract system. Finally, the paper propose, on the on hand, to enlarge the application range of the total bidding system in order to apply more strictly the technology evaluation standards on bidding, and on the other hand, to multiply the competitive proposal and the incentive contract type.

In order to considerably reduce the ambiguity rate, we propose in this article a disambiguation approach that is based on the selection of the right diacritics at different analysis levels. This hybrid approach combines a linguistic approach with a multi-criteria decision one and could be considered as an alternative choice to solve the morpho-lexical ambiguity problem regardless of the diacritics rate of the processed text. As to its evaluation, we tried the disambiguation on the online Alkhalil morphological analyzer (the proposed approach can be used on any morphological analyzer of the Arabic language) and obtained encouraging results with an F-measure of more than 80%.

In order to examine whether the difference between two point estimates of population proportions is statistically significant, data analysts use two techniques. The first is to explore the overlap between two associated confidence intervals. Second method is to test the significance which is introduced at most statistical textbooks under the common assumptions of consistency, asymptotic normality, and asymptotic independence of the estimates. Under the null hypothesis which is two population proportions are equal, the pooled estimator of population proportion is preferred as a point estimator since two independent random samples are considered to be collected from one population. Hence as an alternative method, we could obtain another confidence interval of the difference of the population proportions with using the pooled estimate. We conclude that, among three methods, the overlapped method is under-estimated, and the difference of the population proportions method is over-estimated on the basis of the proposed method.

The rapid development and diversification of technology require that firms should adjust and cope with a high degree of uncertainty. An alternative to these strategic responses is the recent increase in the number of R&D or technological collaborations among firms. There have been continuous researches into the causes and effects of these collaborative relationships, but there is a lack of research that examines the risks involved in the process of collaboration. The researches into essential prerequisites for a successful technological collaboration have remained at the superficial level despite the surge in demand of R&D collaboration. Therefore, this study proposes positive & negative factors affecting the R&D collaboration process and selection point. In addition, a further step in analysis is taken by integrating both the positive & negative factors. This study emphasizes the importance of inter-trust in activating the process factors within the success factors and reducing the possibility of risk factors.

Under circumstances with increasing uncertainty, strategic flexibility has become an essential point on which my R&D management system should be based. Unfortunately the present R&D management system for government sponsored R&D programs cannot be said to be so flexible to adapt appropriately to various threatens such as technological failure, a severe change in competition environment, and so on. In this paper a new scheme for R&D planning and economic assessment with strategic flexibility is suggested and applied to a real R&D program. In the newly suggested R&D management system, economic valuation based on real option theory is performed for various alternative scenarios which have different strategic scheme for R&D process each and the result of the assessment is fed back to R&D planning to choose more superior strategic scheme. Introducing strategic flexibility into R&D planning and economic assessment, the value of R&D project could be remarkably enhanced.

A reliability-based cost-benefit model for the risk management of oil platforms in the formulation of optimal decisions based on life-cycle consideration is proposed. The model is based on structural risk assessments and the integration of social issues and economics into the management decision process. Structural risks result from the platform's exposure to the random environmental loading associated with the offshore site where it is located. Several alternative designs of a typical platform are proposed and assessed from the cost-effectiveness viewpoint. This assessment is performed through the generation of cost/benefit relationships that are used, later on, to select the optimal design.
