Purpose: The purpose of the present study was to examine the causal relationships among hospital nursing organizational characteristics (organizational climate, workload), individual characteristics (experience, education) and outcome variables (job satisfaction, job stress, task performance) by constructing and testing a conceptual framework. Method: Five large general hospitals located in Seoul were selected to participated. The total sample of 245 registered nurses represents a response rate of 94 percent. Data for this study was collected from January to February in 2006 by questionnaire. Path analyses with LISREL program were used to test the fit of the proposed model to the data and to examine the causal relationships among variables. Result: Both the proposed model and the modified model fit the data excellently. The model revealed relatively high explanatory power of work stress (40%), job satisfaction (46%) and task performance (27%) by predicted variables. In predicting work stress, job satisfaction and task performance, the finding of this study clearly demonstrate organizational climate might be the most important variable. Conclusion: Based on the findings of the study, it was suggested that desirable organizational climate was needed to increase the nurses' mental and physical health as well as qualified task performance.

The objectives of this study were to explore the duties and tasks of educational program operation, to develop the performance model including the duties and tasks, and to construct the action manual of the tasks and duties in related with implementing effectively the educational program. The findings of this study were as follows. First, The identifying duties and tasks was 1,942 related with implementing educational program operation based on theoretical job model through activity analysis and experience sampling techniques. Second, the finding duties and tasks was reconstructed through classifying with 9 duties and 88 tasks, and then it was developed as educational program operation model of Korean Rural HRD Center. Finally Third, the implementing manual was constructed including the contents and task-elements.

An action-selection-mechanism(ASM) has been proposed to work as a fully connected finite state machine to deal with sequential behaviors as well as to allow a state in the task program to migrate to any state in the task, in which a primitive node in association with a state and its transitional conditions can be easily inserted/deleted. Also, such a primitive node can be learned by a shortest path-finding-based reinforcement learning technique. Specifically, we define a behavioral motivation as having state-dependent value as a primitive node for action selection, and then sequentially construct a network of behavioral motivations in such a way that the value of a parent node is allowed to flow into a child node by a releasing mechanism. A vertical path in a network represents a behavioral sequence. Here, such a tree for our proposed ASM can be newly generated and/or updated whenever a new behavior sequence is learned. To show the validity of our proposed ASM, experimental results of a mobile robot performing the task of pushing- a- box-in to- a-goal(PBIG) will be illustrated.

태스크내부에서 공급 전압을 조절하는 태스크내 전압 스케쥴링(IntraVS)은 저전력 프로그램을 구현하는 데 효과적인 방법이다. 본 논문에서는 경성 실시간 응용프로그램에서 평균 실행 시간에 대한 정보를 이용하여 전력 소모를 효과적으로 줄이는 새로운 태스크내 전압 스케쥴링 알고리즘을 제시한다. 최악 실행 시간을 사용하여 전압 조절의 결정을 내렸던 기존의 태스크내 전압 스케줄링과는 달리, 제안된 알고리즘은 평균 실행 시간에 바탕을 두고 실행 속도를 조절함으로써 주어진 시간 제약 조건을 만족시키면서도 기존 방법보다 에너지 효율성을 높일 수 있다. MPEG-4 디코더를 이용한 실험 결과, 제안된 알고리즘은 기존의 태스크내 전압 스케줄링에 비해서 전력 소모를 최대 34% 감소시켰다.

As same time of starting on the Korean Long-term Care Insurance System, the government developed a program to train new qualification of long-term care workers. The number of enrolled long-term care workers are 950,000 persons in 2010. Mostly they are working in home based care work places such as home visit care centers and home visit bathing centers covered insurance. The purpose of this study is to understand the difference of task performance requirement according to long-term care workers' responsibilities which divided into home visiting care and home visiting bathing. The comparison analysis was conducted to task performance requirement in basic management, safety management, administration management, practical services. Key result was found that task performance requirement of long-term care workers whose responsibilities are home visiting care were more higher than the home visiting bathing. Finally, To improve quality of home visiting care and home visiting bathing, it is necessary to provide the fields based continuing education and reflect new reimburse system.

The goal of this study is to investigate the course development for the Korean students in the immersion English program. This study describes the detailed curriculum and makes some suggestions to improve the courses for regular, extracurricular, and special activities in the five-week immersion English program managed by KAIST in summer 2001. This immersion English program was designed to develop the students' communicative competence in speaking English with native speakers in the age of globalization, by providing students with the English-speaking immersion setting. The results of the students' tests and the data concerning the program revealed that the program was very significant in improving students' communicative competence focused on communication and presentation and in attaining the high motivation for the natural English communication by performing the student-centered and task-based extracurricular activities and special events.

Task-based programming is becoming the state-of-the-art method of choice for extracting the desired performance from multi-core chips. It expresses a program in terms of lightweight logical tasks rather than heavyweight threads. Intel Threading Building Blocks (TBB) is a task-based parallel programming paradigm for multi-core processors. The performance gain of this paradigm depends to a great extent on the efficiency of its parallel constructs. The parallel overheads incurred by parallel constructs determine the ability for creating large-scale parallel programs, especially in the case of fine-grain parallelism. This paper presents a study of TBB parallelization overheads. For this purpose, a TBB micro-benchmarks suite called TBBench has been developed. We use TBBench to evaluate the parallelization overheads of TBB on different multi-core machines and different compilers. We report in detail in this paper on the relative overheads and analyze the running results.
