In this paper, CPLD low power technology mapping for reuse module design under the time constraint is proposed. Traditional high-level synthesis do not allow reuse of complex, realistic datapath component during the task of scheduling. On the other hand, the proposed algorithm is able to approach a productivity of the design the low power to reuse which given a library of user-defined datapath component and to share of resource sharing on the switching activity in a shared resource. Also, we are obtainable the optimal the scheduling result in experimental results of our using chaining and multi-cycling in the scheduling techniques. Low power circuit make using CPLD technology mapping algorithm for selection reuse module by scheduling.

본 논문은 시간 제약 조건하에서의 모듈 선택 재사용을 이용한 CPLD 저전력 기술 매핑을 제안한다. 일반적인 상위 수준 합성에서의 스케줄링은 실제적인 라이브러리의 복잡한 재사용을 허용하지 않는다. 반면 제안한 알고리즘은 주어진 사용자 정의 모듈을 실제적인 RT 라이브러리 모듈 재사용과 공유된 자원에서의 스위치 활동의 자원 공유하여 스케줄링을 수행한다. 스케줄링은 체이닝과 멀티사이클링을 이용해 다양한 상위 레벨 벤치마크의 환경에서 최적의 스케줄링의 결과를 얻는다. 스케쥴링의 결과 재사용된 자원은 CPLD 저전력 기술 매핑 알고리즘을 이용하여 저전력으로 회로를 구현한다.

The adaptive reuse of 20th-century high-rise architecture poses important questions about the prevalence of authorized discourses in the heritage conservation field. Based on a two-year teaching experience at Tongji University about the adaptive reuse of the Metropolo Hotel (Palmer and Turner, 1934), an iconic historic high-rise building in the Shanghai Bund area, this paper will show the extent to which disciplinary and urban authorized heritage discourses are present in the development of design and representation strategies in adaptive reuse. Using discourse analysis as a method, this paper will make the argument that disciplinary discourses have a limited effect in the practice of adaptive reuse, which is perceived as a fundamentally creative activity. At the same time, the paper reveals how urban discourses have a much more lasting effect, confirming the intimate links between adaptive reuse and the wider phenomena of beautification and gentrification of high-rise listed areas.

Photoreactivation of microorganism following UV-disinfection is one of the research topics of interest in assessing the UV-disinfection performance. Apparent photoreactivation was examined under fluorescent lamp and solar radiation as well as in darkness. Total coliform, fecal coliform, and Escherichia coli were used as indicator microorganisms, and their concentration was monitored with time after UV-disinfection. Under the darkness, their initial concentration of 10∼30 MPN/100 mL increased to the level of 100 MPN/100 mL after 24 hours, which implied that part of damaged microorganisms by UV-disinfection might be repairable with time. Under the fluorescent lamp, photoreactivation was more apparent that their concentration increased up to 1,000 MPN/100 mL which might significantly impair the water uses specially in reuse of reclaimed wastewater. However, their concentration further decreased down to below 2 MPN/100 mL under the solar radiation primarily due to additional disinfection by solar radiation rather than photoreactivation. Samples not disinfected by UV-disinfection also demonstrated substantial decrease of their concentration under solar radiation from about 5,000 MPN/100 mL to less than 30 MPN/100 mL in 24 hours. But direct reuse of effluent without disinfection is not recommended because natural decay by solar radiation may take time and be affected by climatic conditions. The result suggests that photoreactivation of pathogenic microorganisms may not be concerned in agricultural reuse of reclaimed wastewater because solar radiation may provide further disinfection after UV-disinfection.

With the widespread use of smartphones and IoT (Internet of Things), data are being generated on a large scale, and there is increased for the analysis of such data. Hence, distributed processing systems have gained much attention. Hadoop, which is a distributed processing system, saves the metadata of stored files in name nodes; in this case, the main problems are as follows: the memory becomes insufficient; load occurs because of massive small files; scheduling and file processing time increases because of the increased number of small files. In this paper, we propose a solution to address the increase in processing time because of massive small files, and thus improve the processing performance, using the Reuse JVM method provided by Hadoop. Through environment setting, the Reuse JVM method modifies the JVM produced conventionally for every task, so that multiple tasks are reused sequentially in one JVM. As a final outcome, the Reuse JVM method showed the best processing performance when used together with CombineFileInputFormat.

This paper searches Internet auction sites to study consumer willingness to reuse and consumer satisfaction, along with its frequency of usage and evaluation. This study also examines the differency in the frequency of usage, the number of products purchased, consumer satisfaction and willingness to reuse, and evaluation of the auction sites according to the characteristics of consumers' socio-economic factors and the auction site itself. Determinant variables is investigated in the level of consumer satisfaction. The results of this study are as below: First, consumers used auction sites frequently, especially when they were in their 20s, intended to purchase clothes, and thought the delivery time would be short. In addition, consumers were more likely to purchase products, with low income buy first pay later, and short deliberation. Second, consumers, unemployed and in their 50s, sell-purchase among consumers were less likely to have a willingness to reuse the auction site. However, consumers with an experience to buy clothes or products with a price between 50,000 and 100,000 won were more likely to have a willingness to reuse the site. Third, consumer satisfaction with auction sites were higher among those who were females; responsible as a consumer; full of experiences; and received the product within a short period of time. Lastly, the willingness to reuse auction sites was positively related to the following type of consumers: single, employed, and responsible as a consumer.

Objectives : The purpose of this paper was to examine quantitative methods for estimating and detecting local text reuse in the texts of East Asian Traditional Medicine. Methods : We introduce techniques that estimate the volume of local text reuse with n-gram and those that directly detect the reuse with the Smith-Waterman algorithm (SW algorithm). Based on this, the estimation and detection of local text reuse were carried out for 『Donguibogam』 and 『Huangdineijing·Suwen』. Results : Estimates with n-gram had more errors than methods with SW algorithms. SW algorithms detected suspected strings directly with local text reuse, resulting in more accurate results. Conclusions : Although n-gram does not accurately find local text reuse, its high speed makes it a preferable method for certain purposes, such as screening similar documents. On the other hand, SW algorithms have the advantage of being relatively good at finding similar phrases suspected as local text reuse even if the strings do not completely match. However, due to its excessive consumption of time and computing resources, its benefits are limited to cases where precise results are required.

This paper proposes a graph-theatrical approach to optimize spatial reuse by adopting a technique that quantizes the channel information into single bit sub-messages. First, we introduce an interference graph to model the network topology. Based on the interference graph, the computational requirements of the algorithm that computes the optimal spatial reuse factor of each user are reduced to quasilinear time complexity, ideal for practical implementation. We perform a resource allocation procedure that can maximize the efficiency of spatial reuse. The proposed spatial reuse scheme provides advantages in beamforming systems, where in the interference with neighbor nodes can be mitigated by using directional beams. Based on results of system level measurements performed to illustrate the physical interference from practical millimeter wave wireless links, we conclude that the potential of the proposed algorithm is both feasible and promising.
