이 논문에서는 Best Imaginary Level-Iterative(BILI) 분할 방법이라 부르는 새로운 하드웨어/소프트웨어 분할 알고리즘을 제안하다. 이 분할 알고리즘은 여러 개의 하드웨어와 소프트웨어로 이루어진 시스템에 대해서 분할을 할 수 있을 뿐만 아니라, 여러 가지의 구현 가능성 중에서 적은 비용의 구현을 선택하는 문제까지 해결한다. 이 분할 알고리즘은 기존의 분할 알고리즘인 GCLP와 비교하여 약 15%의 비용 감소를 가지고, 항상 최적의 해를 찾는 장수 선형 프로그래밍과 비교하여 약 5%정도의 비용 증가를 가진다. This paper presents a fast partitioning heuristic for hardware/software codesign called Best Imaginary Level-Iterative(BILI) partitioning which iteratively applies BIL heterogeneous multiprocessor scheduling heuristic to minimize the cost within the given time constraint. The proposed algorithm solves the partitioning problem with the implementation bin selection problem as well as architectures with multiple software modules. It costs about 15% less than the GCLP and at most about 5% more than the optimal solution obtained by the Integer Linear Programming(ILP) algorithm.

이종 프로세서를 위한 정적인 스케줄링 휴리스틱

오현옥(Hyunok Oh),하순회(Soonhoi Ha) 한국정보과학회 1998 정보과학회논문지 : 시스템 및 이론 Vol.25 No.12

본 논문에서는 서로 다른 수행 시간을 가지는 다중 프로세서를 대상으로 한 Best Imaginary Level (BIL) 스케줄링이라는 정적인 비선점 스케줄링 휴리스틱을 제안하였다. 스케줄링의 대상이 되는 입력 그래프는 선후 관계의 제약 조건을 가지는 비순환 그래프이며, 그래프 상의 각 노드는 각각의 프로세서에서 다른 수행 시간을 가진다. 노드의 정적인 레벨(BIL)은 프로세서간의 통신(IPC)을 고려하고 프로세서의 이종성도 고려한다. 제안된 스케줄링 기법이 입력 그래프의 모양이 선형인 경우 최적의 스케줄링 결과를 생성해 내는 것을 증명하였다. BIL 스케줄링은 현존하는 스케줄링 기법인 general dynamic level (GDL) 스케줄링 기법과 비교해서 다양한 형태의 무작위로 만들어낸 입력 그래프에 대해 약 20%의 성능 향상을 가져왔다. This paper presents a static scheduling heuristic called Best Imaginary Level (BIL) scheduling for heterogeneous processors. The input graph is an acyclic precedence graph, where a node has different execution times on different processors. The static level of a node, or BIL, incorporates the effect of interprocessor communication (IPC) overhead and processor heterogeneity. The proposed scheduling technique is proven to produce the optimal scheduling result if the topology of the input task graph is linear. The performance of the BIL scheduling is compared with an existing technique called the general dynamic level (GDL) scheduling with various classes of randomly.

The purpose of this study was to examine how the participation period and level of satisfaction on leisure sports activity impact multidimensional perfectionism. Data sources for the research were multidimensional perfectionism scale. The researcher took 224 participants of leisure sports activity and used multidimensional perfectionism scale test to measure multidimensional perfectionism. Used SPSS 11.0 and AMOS 7.0, Data were analyzed by exploratory factor analysis and confirmatory factor analysis, reliability test, correlation analysis, and MANOVA. Through this method of research results were as follows. First, multidimensional perfectionism were categorized into 3 factor: self-oriented perfectionism, other oriented perfectionism, social prescribed perfectionism. Second, multidimensional perfectionism was not influenced by participation period sports activity. Third, multidimensional perfectionism was influenced by level of satisfaction sports activity. Fourth, social prescribed perfectionism among multidimensional perfectionism was influenced by participation period and level of satisfaction on sports activity.

The purpose of this study is to investigate the effect of the emotional dissonance on emotional exhaustion and customer orientation of golf course caddies. A total of 240 questionnaires were distributed using convenience sampling method to golf course caddies who are working 10 golf places. The results analyzed with frequency analysis, factorial analysis, reliability, correlation, single regression analysis using SPSS(Window ver. 18.0). The results were as follow. First, golf course caddies of emotional dissonance significantly influenced on the emotional exhaustion. Second, emotional dissonance significantly influenced on the customer orientation. Finally emotional exhaustion significantly influenced on the customer orientation.

The purpose of this study is to understand the relations of influence of a college student’s self-identity on career decision-making, and to provide basic materials necessary for career decision-making through the effect of Pilates program satisfaction; accordingly, this study deducted the results as follows with the survey, to which 336 college students replied, as the center, through the Smart PLS 2.0 M3 program. First, a college student’s self-identity was found to have the positive relations of influence on career decision-making. Second, a college student’s self-identity was found to have the positive relations of influence on the Pilates program. Third, it was found that Pilates program satisfaction had the positive relation of influence on career decision-making. Putting together the results as above, this study confirmed that the Pilates program is an exercise program having a positive interaction on a college student’s self-identity level. Particularly, this study also confirmed that the strength of the Pilates program in having a positive effect on a college student’s psychological, physical aspects was positively conveyed to a college student.
