Recently, many research groups have focused on GPGPUs in order to improve the performance of computing systems. GPGPUs can execute general-purpose applications as well as graphics applications by using parallel GPU hardware resources. GPGPUs can process thousands of threads based on warp scheduling and CTA scheduling. In this paper, we utilize the traditional CTA scheduler to assign a various number of CTAs to SMs. According to our simulation results, increasing the number of CTAs assigned to the SM statically does not improve the performance. To solve the problem in traditional CTA scheduling schemes, we propose a new IPC-based dynamic CTA scheduling scheme. Compared to traditional CTA scheduling schemes, the proposed dynamic CTA scheduling scheme can increase the GPU performance by up to 13.1%.

To secure resources, submarine environment should be firstly explored. On that occasion, the withdrawal of the instrument is important and the submarine ultrasonic wave should be stably identified regardless submarine environment and passive factor. In the existing control methods, the control informations, received from an observation instrument, are identified used by hardware and repeatedly compared with standard information. Hereupon, a marine observation instrument remote control system using the combination of FSK and ASK that was improved its controllability and movability was presented in this paper. Likewise, the logicality of communication algorithm were ascertained by experiments.

The speedy advance of network technology with axis internet gives the business opportunities to the today's firms and also makes them apply the intranet and groupware to their management. And, the firms admit these technological changes and expand the investment on the network. But, the firm's plans to cope with the changes which is caused by the appliance of the network technology to their firms are not prepared yet. Especially, the firm's managers are particularly wondering on how to use the already invested network hardware. In this article, we investigated the advance process and direction of the network technology like internet, groupware, and intranet, the firm's efforts to build network system, and the changes of the business process procedures. To apply the new technologies such as intranet and groupware into the business, the firms have to change the function of computer center from the programming to the user training and the management of network and computing resources, and they need to standardize their business process.

This paper presented a FPGA design of SEED, which is the Korea standard 128-bit block cipher. In this work, SEED was designed technology- independently for other applications such as ASIC or core-based designs. Hence in case of changing the target of design, it is not necessary to modify design or need only minor modification to reuse the design. Since SEED algorithm requires a lot of hardware resources, each unit was designed only once and used sequentially. So, the number of gates was minimized and SEED algorithm was fitted in FPGA without additional components. It was confirmed that the rate of resource usage is about 80% in ALTERA 10KE and the SEED design operates in a clock frequency of 131.57 MHz and an encryption rate of 29 Mbps.

The purpose of this study is to examine the preparation of medical institutions for Russian medical tourists. The data for this study include 44 cases which were selected from Korea Health Industry Development Institute list. Data were collected through the e-mail survey from Feb. 24 to Jul. 1 in 2014. The results of the study are as follows. Overall, tertiary hospitals were well prepared in hardware resources and structure(e.g. the number of coordinators and marketers, accreditation)compared to hospitals and clinics. On the other hand, hospitals were well prepared in service process protocol.

The smart media (SM) industry has demonstrated that it has the characteristics to increase user innovative activities, enhance open innovativeness, and increase the segmentation of innovation value. This study introduces and evaluates an innovation system that reflects the characteristics of the SM industry. We categorize the SM industry into hardware, network, platform, and content industries and perform an AHP analysis (based on a survey of 96 experts) to evaluate the relative importance of the factors/factor groups affecting the creation of innovation. The results show that 'collaboration activity" is a more important factor than other innovation factor groups (financial support, R&D, policy environment, human resources) in the SM industry. The results also show that the important factors/factor groups differ by industry.

The WRR scheduling algorithm is widely used in ATM networks due to its simplicity and the low cost of hardware implementation. It guarantees minimum cell rate according to the weight of each queue. The fairness is a important factor for ABR service. That is, Scheduling algorithm allocates network resources fairly to each VC. In this paper, we propose a scheduling algorithm for satisfying the two fairness criteria, MCR plus equal share and Maximum of MCR or Max-Min share, among the six criteria defined by ATM Forum TM 4.1 specification. The WRR, Nabeshima et al, and the proposed scheduling algorithms are compared with respect to fairness and convergence time throughout experimental simulation.

본 논문은 HEVC $4{\times}4$ IDCT/IDST를 위한 통합형 아키텍쳐를 제안하여 면적을 줄이고자 한다. $4{\times}4$ IDCT와 $4{\times}4$ IDST는 일반적으로 따로따로 만들어서 멀티플렉서로 연결하여 사용하나, 제안하는 아키텍쳐 구현에서는 두 블록을 합쳐서 곱셈기 등의 하드웨어 자원을 공유하여 면적을 줄였다. 0.18um 공정에서 합성한 결과 게이트 수가 약 2,795 게이트로 기존 아키텍쳐 대비 9.44% 감소함을 확인하였다.

Under the concept of global economy, the enterprises are assigning design and production environments around the world in different areas. In shipbuilding companies, a serious problem of information exchange emerges as companies use traditional hardware and very distinct softwares appropriate to their field of expertise. To overcome the decreased productivity due to the interruption of information, the concept of simultaneous engineering and concurrent design becomes very significant. In this article, the concept oj collaborative design based on internet environments is described. Especially, the core technologies to achieve collaborative design environments among shipbuilding companies, ship owners, ship classification societies, model basin, and consulting companies are adopted.

Most of us spend the greater part of our lives in the kitchen, but of all the man environments it maybe the least well-explored share commitment to a cleaner and healthier environment. It has long been kitchen system belief that the environment is a precious gift. In case of built in kitchen system, because it depend upon the earth's resources to design and manufacture steel hardware products, human beings feel an abiding responsibility to act wisely in the environmental choices we make, large and small, every day. Built in kitchen system, designed and coordinated by study of designer, represents an open, complete, free and 'focused' way of conceiving, furnishing and organizing one's own kitchen. A space rich in technical values and home warmth, where few, simple and carefully designed components distinguish and characterize the various work spaces, from the area, intended for preparing and washing food, to the cooking area, and to a wide range of multivalent pieces of furniture, wood paneled wall units and shelves.
