  • Construction space of Japan suggests the factor of speculation to human and reveals tradition. The speculation can be embodied in the aspect of space and human's mental aspect is expressed as a main factor of tradition space of Japan. The purpose of this study is to research expression characteristic of speculation space, shown in the architecture of modem architect, Tadao Ando, who succeeds the concept. His works surveyed through research contain the emotion of nature and human, which are traditional factors of Japan. Moreover, it is reinterpreted by modem space, delivers its function of space and physical factor to user and grants value to activity and behavior of user residing in the space. Users recognize movement, create new meaning of space and accept physical barrier in the space. In conclusion, it can be said that the space of speculation is not a simple visual thing but a frame of visual structure, which is invented for embodiment. The factors show the Japanese architecture, real and contemplating one, which is positive in real life and allows experience. Through the conditions above, the researcher can find the meaning from the aspect that modem architecture of Japan is planned on the basis of concept of speculation.

  • Purpose - The postponement strategy, which delays the form, place, and production of products as late as possible, has been widely considered as a competitive supply chain management scheme in an era of mass customization and modular manufacturing. An interesting business phenomenon is that not all manufacturing/logistics firms choose the postponement strategy. Given that postponement is a counter-measure to speculation, which has some advantages under certain environments, the current imprudent inclination toward the postponement strategy may cause firms to lose the potential of the speculation strategy, an alternative strategy in supply chain management. Building on the logistics and manufacturing literature, this study examines characteristics of two contrasting strategies, postponement and speculation, and major factors favoring each strategy. Research design, data, and methodology - We apply the profiling approach to two business cases, HP printer and LG mobile phone. The profiling approach is a method of choosing a particular strategy aligned with environmental factors. While various approaches have been used to check the fit between a business strategy and environmental factors, the literature on manufacturing strategy and logistics has commonly adopted the profiling approach. Major factors used in profiling variables are derived from the literature. Two samples, HP printer and LG mobile phone, are selected, because they represent major characteristics appropriate for each strategy. The profiling is based on data from semi-organized interviews with managers. Results - The profiling approach shows that the postponement strategy is a suitable one for HP printers. Most factors, such as product life cycle, large production volume, low-price, product value, and monetary density, support delaying end products until as late as possible. Despite some exceptions, such as delivery time and economy of scale, our analysis states that the overall profile of HP printer is favorable for the postponement strategy. On the other hand, LG mobile phone may adapt the speculation strategy. Although it has large production volume and low delivery frequency, most characteristics support the speculation strategy for this product. An interesting finding is that, despite common perception that advanced technology products such as mobile telephones favor the postponement strategy, profiling proposes the speculation strategy for this product. Conclusions - Our analysis shows that speculation is not the universal option for supply chain management, and that, when choosing a specific strategy, one should consider many factors simultaneously. A major implication of our work is to emphasize the role of environmental factors such as supply chain variables in choosing an inventory strategy, and the importance of fit rather than solely strategic orientation. A theoretical contribution is to demonstrate the benefit of the simultaneous consideration of business variables in choosing specific strategies. For practitioners, our work leads us to consider the existence and the potential of speculation as a counter-measure to postponement. In addition, the comprehensive framework in this research may be instantly used in examining a practical strategy.

  • 토지 투기는 공간상에서 발생하는 것이며, 본 연구의 목적은 공간적 시각에서 토지투기를 해석하여 토지 투기 발생 가능 지역들에 대한 효과적인 의사결정을 수행하고자 하는 데에 있다 이 때, 공간적 해석의 초점은 공간 연속성의 인식과 공간 상관성의 고려라는 2가지 측면에 두었다. 먼저, 공간 연속성을 인식하기 위해 퍼지 집합을 사용하여 모든 지역에 0-1사이의 값을 부여하였고. 공간 상관성을 고려하기 위해 국지적 상관관계 분석을 수행하였다. 또한 이 두 가지 방법을 효율적으로 통합하여 대상 지역 내에서 토지 투기에 대한 효율적인 의사결정들 하기 위한 방안으로 컴퓨터 기반의 의사결정지원 도구 중 하나인 공간 전문가지원 시스템을 도입하였다. 이 후, 사례 분석으로 서울ㆍ경기 지역의 2001년 토지 투기 발생에 대한 의사 결정을 수행하였다.

  • 투기과열지역은 투기의 발생 가능성이 높은 지역으로, 각종 부동산대책의 주요 대상이 된다. 본 연구에서는 부동산 가격변동의 공간패턴을 모형화함으로써 투기과열지역의 공간패턴을 제안하고자 한다. 부동산 가격은 합리적 또는 적응적 소유자 수요자의 경계행위에 의해서 결정되고, 가격변동의 공간패턴은 이들의 경제행위 경향에 의해서 형성된다고 모형화하였다. 일정 지역에 적응적 소유자와 수요자가 다수인 경우, 이 지역은 타 지역에 비해 가격상승 폭이 높고 주변 부동산과 가격상승이 동시에 일어나는 가격변동 핫스팟 패턴으로 정의하였다. 투기과열지역은 최대의 미래 기대이익을 얻고자하는 적응적 소유자와 수요자에 의해서 형성되기 때문에 이 지역의 공간패턴은 가격변동 핫스팟 패턴으로 정의할 수 있었다.

  • 이 논문은 헤지펀드 등 금융기관들의 금융적 투기가 효율시장가설의 주장과 달리 상품시장의 가격변동과 왜곡을 발생시킬 수 있고, 따라서 이러한 시장에 대한 엄격한 규제가 필요하다는 것을 주장한다. 효율시장가설은 헤지펀드가 가격위험을 헤징하고 정확한 가격을 발견하는데 중요한 역할을 한다고 주장하지만, 이 글은 이와 반대로 선물시장에서 헤지펀드의 거래가 증가할수록 가격이 장기균형가격으로 수렴하는 속도가저하되는 등의 왜곡현상이 나타난다고 주장한다. 또한 선물시장에서의 투기적 거래가 역사적인 수준으로부터 크게 벗어나지 않았다는 주장과달리, 과잉투기(excessive speculation)가 존재하였으며 과잉투기를 이끈 헤지펀드 등에 의해 선물가격이 비정상적으로 폭등하였다. 선물시장에서의 가격폭등은 현물-선물등가법칙에 의해 곧바로 현물시장의 가격폭등을 유발시키고, 그 결과 경제 전체적으로 나쁜 영향을 주게 된다.

  • Microprocessors are becoming increasingly vulnerable to soft errors due to the current trends of semiconductor technology scaling. Traditional redundant multi-threading architectures provide perfect fault tolerance by re-executing all the computations. However, such a full re-execution technique significantly increases the verification workload on the processor resources, resulting in severe performance degradation. This paper presents a pro-active verification management approach to mitigate the verification workload to increase its performance with a minimal effect on overall reliability. An anomaly-speculation-based filter checker is proposed to guide a verification priority before the re-execution process starts. This technique is accomplished by exploiting a value similarity property, which is defined by a frequent occurrence of partially identical values. Based on the biased distribution of similarity distance measure, this paper investigates further application to exploit similar values for soft error tolerance with anomaly speculation. Extensive measurements prove that the majority of instructions produce values, which are different from the previous result value, only in a few bits. Experimental results show that the proposed scheme accelerates the processor to be 180% faster than traditional fully-fault-tolerant processor with a minimal impact on overall soft error rate.

  • General purpose computing applications have not yet been thoroughly explored in procedure level speculation, especially in the light-weighted profiling way. This paper proposes a light-weighted profiling mechanism to analyze speculative parallelism characterization in several classic general purpose computing applications from SPEC CPU2000 benchmark. By comparing the key performance factors in loop and procedure-level speculation, it includes new findings on the behaviors of loop and procedure-level parallelism under these applications. The experimental results are as follows. The best gzip application can only achieve a 2.4X speedup in loop level speculation, while the best mcf application can achieve almost 3.5X speedup in procedure level. It proves that our light-weighted profiling method is also effective. It is found that between the loop-level and procedure-level TLS, the latter is better on several cases, which is against the conventional perception. It is especially shown in the applications where their 'hot' procedure body is concluded as 'hot' loops.

  • The major purpose of this paper is to examine two closely related issues. An attempt is made here to examine internationally high land price in Korea from the perspectives of market fundamentals (MF) and bubble theory, respectively. Another theoretical issue, whether land speculation can result in market failure, is also examined. It has been concluded that the primary causes for the rapid increases in land prices in Korea, could be found in the perspective of MF. (1) The financial intermediaries has been controlled by the government since 1960s. Real Interest rates in the commercial banks has been controlled at the level of zero or sometimes negative; scarce financial resources has been rationed by the government. The governmental control of the bands has also resirained the development of securities market. Money, which can not find the appropri opportunity for saving in financial market, moves to land market. (2) Socially created land value, based on rapid economic gorwth and big public investment, has been appropriated mainly by the private: The effective tax rate of land holding tax has been under 0.02 percent; Real Estate Capital Galns Tax has, in fact, affected few persons, mainly because examptions and preferential taxation have been widely permitted. (3) The government has ploaced severe limitations on rural-to-urban land conversion, although the demand for urban uses has repidly grown. All factors above caused the cyclical land speculation. This, in turn, created the myth that land prices will inevitably continue to rise. Based on the myth, the growing bubble in land price has been created. This is the secondary reason for high land price relative to income in Korea. It is also shown that it is possible that speculation in land results in market failure because land is fixed in quantity and can be used for production and speculation purposes simultaneously.
