고성능 슈퍼스칼라 프로세서에서 값 예측 실패 시에 잘못 예측된 값을 사용하여 모험적으로 수행된 명령들만을 순차적으로 취소하고 복구한 후에 재이슈하는 값 예측 실패 복구 메커니즘을 제안한다. 제안된 복구 방식은 값 예측이 틀린 종속명령만을 선택적으로 재이슈하여 불필요한 재이슈를 줄임으로써 값 예측 실패 시에 손실을 줄인다. 또한 기존의 방식들처럼 잘못 예측된 명령에 종속적인 명령들의 한번에 병렬로 검색하지 않고 명령들의 종속체인을 따라 순차적으로 검색함으로써 프로세서의 클럭 사이클에 영향을 미치지 않으면서 하드웨어의 구현의 복잡성을 줄인다.

Recently, failure rates of Kosdaq IPO firms are increasing and their survival rates tend to be very low, and when these firms do fail, often times backed by a number of governmental financial supports, they may inflict severe financial damage to investors, let alone economy as a whole. To ensure investors' confidence in Kosdaq and foster promising and healthy businesses, it is necessary to precisely assess their intrinsic values and survivability. This study investigates what contributed to the failure of IPO firms and analyzed how these elements are factored into corresponding firms' stock returns. Failure risks are assessed at the time of IPO. This paper considers factors reflecting IPO characteristics, a firm's underwriter prestige, auditor's quality, IPO offer price, firm's age, and IPO proceeds. The study further went on to examine how, if at all, these failure risks involved during IPO led to post-IPO stock prices. Sample firms used in this study include 98 Kosdaq firms that have failed and 569 healthy firms that are classified into the same business categories, and Logit models are used in estimate the probability of failure. Empirical results indicate that auditor's quality, IPO offer price, firm's age, and IPO proceeds shown significant relevance to failure risks at the time of IPO. Of other variables, firm's size and ROA, previously deemed significantly related to failure risks, in fact do not show significant relevance to those risks, whereas financial leverage does. This illustrates the efficacy of a model that appropriately reflects the attributes of IPO firms. Also, even though R&D expenditures were believed to be value relevant by previous studies, this study reveals that R&D is not a significant factor related to failure risks. In examing the relation between failure risks and stock prices, this study finds that failure risks are negatively related to 1 or 2 year size-adjusted abnormal returns after IPO. The results of this study may provide useful knowledge for government regulatory officials in contemplating pertinent policy and for credit analysts in their proper evaluation of a firm's credit standing.

This study investigates the relationship between fear of failure of potential entrepreneur's psychological characteristics and entrepreneurial intentions using the mediation variables of planned behavior model. There are many existing prior research related to the entrepreneurial intentions, but they were mostly focused only entrepreneurial success factors. So in this study we focused on fear of failure of potential entrepreneur. To know the influence of the fear of failure related to entrepreneurial intention, we using the scale of PFAI (Performances Failure Appraisal Inventory). The purpose of this study is to examine an impact of fear of failure on entrepreneurial intention and add to mediating factors - attitude toward the acts, subjective norm, perceived behavior control - on the relationship between fear of failure and entrepreneurial intention. Also we examined entrepreneurial education as moderating effect in order to offset the fear of failure. In order to test research model, we collected data from 321 undergraduate students. To test the research questions and hypotheses, we employed SPSS 21.0 anf AMOS 18.0 for validity, reliability, confirmatory factor analysis, and structural model analysis. The results were as follows. First, the fear of failure negatively related to attitude toward the behavior and subjective norm. Second, attitude toward the behavior and subjective norm positively related to entrepreneurial intention in consistent with previous studies. Third, attitude toward the acts and subjective norm in TPB variables have full-mediation effects between fear of failure and intrepreneurial intention. Fourth, The moderating effects of entrepreneurial effect was not significant. The negative relationship between fear of failure and attitude toward the acts and subjective norm was even slightly stronger who have taken the entrepreneurial class group. We discuss the theoretical and managerial implications, and provide suggestions for future research.

While venture creation is considered to be of high social and economic importance, entrepreneurial outcomes are inherently uncertain and that failure is thus a central feature of entrepreneurship. Although failure in entrepreneurship is pervasive and critical, the impact of prior failure on future entrepreneurship has not received significant attention in the literature. Although failure is a painful and costly experience for entrepreneurs, it can also provide a powerful learning opportunity for those experiencing it. It has been argued that entrepreneurial failure is not just a individual problem but a matter of social concern. As part of the restarting business support system, entrepreneurial re-education program is provided to support failed entrepreneurs. The aim of this study is to examine the effects of failed entrepreneurs' prior entrepreneurial experience and re-education on subsequent venture creation. Moreover, this study also examined the moderating effects of entrepreneurial motivation. For the analyses, we surveyed the entrepreneurs who tried to re-start the subsequent business after the entrepreneurial failure through the "Revitalization Center for Strained Entrepreneur". The result found that failed entrepreneurs who learned a lot from their previous founding experience were more likely to re-start their subsequent business. The failed entrepreneurs who learned a lot from entrepreneurial re-education program were more likely to re-start their subsequent business. Moreover, the positive effect of failed entrepreneurs' previous founding experience and entrepreneurial re-education program on re-starting subsequent business was found to be weaker when entrepreneurial extrinsic motivation was high.

Start up a company is critical to the regional economy and job creation and so get support from government and other organizations, but there are still exist of high rate of failure and CEO's stressful fear of failure. New firms are of utmost importance for the vitality of national economic driving forces but for those failed firms, they caused social and economic problems directly and indirectly, and brought frustration to the founders. The many education and research programs about entrepreneurship and venture creation were undertaken by the country and organizations, but the education and research about the vigilance of failed to start up company were almost ignored. If the attention can be put into the research about failed companies and the research can make the founders and pre-CEOs aware the failure of establishing a company, that would be very valuable as scenarios to see the company risks. This case study shows the finding the reasons which caused the failure of small venture companies and it's implications in the filed of establishing companies. The technology based venture company which had run 10 years in Daedeok's IT field was selected as the research object. The results show that the important factors such as entrepreneur characteristics(lack of communication and management knowledge), business management(lack of business expertise) and technology(loss of unique feature of product and lack of product extension) were the root cause of failures.

The Korean government is building a virtuous cycle of startups and venture businesses for a dynamic, innovative economy. This ecosystem is made possible when a social environment that embraces tolerance and turn business failure into re-startups and challenging venture startups by outstanding entrepreneurs are present. Due to the government's efforts to promote start-ups and venture businesses, their number has been increasing annually, but the efforts to create a social environment for re-startups and establish a relevant institution have recently started. This study is aimed at providing policy direction for re-startups by getting policy implications after identifying the current status of domestic failed businessmen' re-startups based on previous researches on failed businessmen. This study also reviewed advanced nations' cases and made international comparison of re-startup policies. Before the startup culture that recognizes failure as the stage for success is formed as in the U.S., it is necessary to create a legal basis for continuously pushing for the rechallenge policy of EU's Small Business Act and establish and operate the private sector-driven revitalization council of SMEs in Japan. It is also necessary to consider the guarantee of failed businessmen' livelihood. If additional research and government policies are added to the conclusions made on the policy implications, this research will provide an in-depth insight for revitalizing domestic re-startup.

An overlay network is a virtual network which is constructed on top of a physical computer network. A node in the overlay network is connected through virtual or logical links, where each link corresponds to a path of the links in the underlying physical network. Overlay networks are suitable for sharing heterogeneous resources in distributed environments, However, overlay networks are limited for achieving reliable communication that failure detection in overlay networks is a very important issue. In this paper, we review conditions of conventional failure detection and propose a new approach to failure detection and resilience which can be applied to HRing (Hierarchical Ring) overlay networks. The proposed method consists of the failure detection and the failure resilience phases. Because it utilizes the characteristics of the HRing overlay network for failure detection, it can reduce unnecessary network traffic and provide better scalability and flexibility. We also analyzed and evaluated the performance of the proposed approach through simulations.
