코칭에 대한 실무적 관심이 높아졌음에도 불구하고 이에 대한 학문적 정의와 발전은 아직 미약한 실정이다. 본 연구의 목적은 기업현장에서 이미 광범위하게 수용된 코칭이 직무성과에 기여하는 실제적 영향과 메커니즘을 밝히는 것이다. 대다수 선행연구들은 코칭교육의 우수성이나 효과성에 대한 선언적 평가에 그쳤다는 한계가 있었다. 이를 극복하고자 코칭 리더십(managerial coaching)이 직무특성이론의 동기부여과정에 개입하는 영향을 실증하고, 코칭교육이 아니라 관리자의 코칭활동에 집중하는 행동주의적 접근을 시도하였다. 연구모형을 검증하기 위하여 국내 금융기업의 조직구성원 453명에 대한 설문자료를 바탕으로 다수준 분석을 실시하였다. 분석 결과, 코칭 리더십이 조직구성원의 직무성과에 미치는 긍정적인 직접효과를 확인할 수 있었다. 또한 핵심직무특성 중에서 직무유의성(job meaningfulness) 및 자율성(autonomy)과 직무성과의 관계를 코칭리더십이 긍정적으로 조절하는 수준 간 영향(cross-level moderating effect)이 유의하게 나타났다. 직무특성의 요건에 따라 집중해야 할 코칭의 기술과 방향이 최적화 관점에서 모색되어야 한다는 본 연구의 시사점은, 기업현장에서 광범위하게 수행된 코칭교육이 간과했던 실천적 공백을 메우는 데 기여할 것으로 기대한다.

지금까지 건설산업은 재무 중심의 성과측정에 주로 의존하여 왔다. 또한 성과측정시스템에 관한 연구는 대부분 프로젝트 레벨에서 이루어졌다. 그러나 최근 들어 산업 또는 기업 레벨의 성과측정 및 관리에 대한 요구가 높아지고 있다. 최근의 몇몇 선행연구들은 기업 레벨의 성과측정을 위한 지표, 측정방법, 개념적 모델 등을 제시한 바 있다. 본 연구는 이러한 연구 결과들을 활용하여 건설산업 참여기업들(발주기업, 건설회사, 설계 ${\cdot}$ 엔지니어링회사)을 위한 web 기반의 성과 및 정보화수준 측정 시스템을 개발하였다. 또한 국내의 78개 기업들로부터 수집한 성과 데이터를 이용한 시스템 테스트 및 성과분석을 수행하였으며, 마지막으로 시스템의 개선 및 효과적 활용을 위한 이슈들을 제시하였다.

Prior studies were limited in the comparison of false belief tasks with desire tasks due to lack of consideration of level of executive functions. To compensate for this, executive functions were included in new preference-related and game-related tasks of conflicting desire. These tasks were administered to 246 preschoolers ranging from 2.5 to 4 years of age. Statistical analysis was by one-way ANOVA and repeated measures ANOVA. Results showed significant main effects depending on age and task type. Younger children lacked ability of executive function, such as inhibition and working memory. Older preschoolers averaged better scores on task performance, showing that it is difficult for younger children to control their own desires and select the contradicted view.

In modern computer architectures, caches are widely used to shorten the gap between processor speed and memory access time. However, caches are time-unpredictable, and thus can significantly increase the complexity of worst-case execution time (WCET) analysis, which is crucial for real-time systems. This paper proposes a time-predictable two-level scratchpad-based architecture and an ILP-based static memory objects assignment algorithm to support real-time computing. Moreover, to exploit the load/store latencies that are known statically in this architecture, we study a Scratch-pad Sensitive Scheduling method to further improve the performance. Our experimental results indicate that the performance and energy consumption of the two-level scratchpad-based architecture are superior to the similar cache based architecture for most of the benchmarks we studied.

There have been a lot of researches about KM(knowledge management) in domestic and foreign countries since 1990. Especially, there have been a lot of researches about enabler of KM, knowledge asset etc. but these are insufficient researches about performance measure of knowledge management considering maturity of KM. In addition, performance measure and maturity considering enabler to manage successful knowledge as well as knowledge asset which can be the following result are not the sufficient situation. Therefore, this study makes developmental levels of the inside and outside of the corporate by observing previous studies about the maturity of knowledge management and classifies enabler of knowledge management and measure item about knowledge asset by level, considering the features of each developmental level. And it is designed to propose maturity measure methods considering maturity level of actual knowledge management item by drawing indicator to measure classified items.

The study investigated pre-service teachers' knowledge and computational skills by using Triangular Arithmagon. Participants included 90 pre-service teachers from two schools in the United States and Taiwan. The Triangular Arithmagons Test (TAT) was used to measure pre-service teachers' performance in whole number, fractions, and decimals operations (i.e., addition, subtraction, multiplication, and division), each of which included level-1 (basic) and level-2 (advanced) tests. MANOVA analysis was performed to compare the performance between teachers from the United States and Taiwan. Results indicated that overall, pre-service teachers in Taiwan outperformed those in the United States, especially on the advanced-level tests. Pre-service teachers in the United States were found to have poor ability of solving complex operation problems. Different curriculum plans and teaching methods may lead to the performance gap between the two countries.

An efficient two-level domain decomposition parallel algorithm is suggested to solve large-DOF structural problems with nonlinear material models generating unsymmetric tangent matrices, such as a group of plastic-damage material models. The parallel version of the stabilized bi-conjugate gradient method is developed to solve unsymmetric coarse problems iteratively. In the present approach the coarse DOF system is solved parallelly on each processor rather than the whole system equation to minimize the data communication between processors, which is appropriate to maintain the computing performance on a non-supercomputer level cluster system. The performance test results show that the suggested algorithm provides scalability on computing performance and an efficient approach to solve large-DOF nonlinear structural problems on a cluster system.

Company Social Networks (CSN) has emerged as a commonly used marketing channel. One of the most important advantages in CSN is the user's voluntary behavior as a relational performance. We classified level of voluntary behavior, as 'consumption', 'active participation', and 'creative contribution' to comprehend different relational performance of CSN. Moreover, we proposed research model to compare positive attitude and negative attitude. This study aims to investigate 'the process of user's voluntary behavior in CSN' which is causal relationship between benefits of CSN, user's attitude and voluntary behavior. Empirical results with 175 valid questionnaire data revealed that CSN benefit factors played a significant role in trust and distrust. Based on these effects, trust and distrust have different influences as level of voluntary behavior, just as proposed. For practitioners, it is crucial finding that users are more active behavior based on strong trust.

The present study analyzed data from 417 grandchildren in the fifth grade of the elementary school with regard to patterns of contact and the content and the level of grandmothers role performance. Major findings were as follows; 1) The most frequent of association occuring between grandmothers and grandchildren was telephoning, next visiting and writing. The mothers, attitude and geographical proximity were consistently related to the level of the contact between grandmothers and grandchildren. 2) The family type, the attitude of the mothers and the health condition of grandmothers were related to the level of the grandmothers role performance. The role of the grandmothers consists with six dimensions of discipliner, surrogate parenting, interference, historical and sex role adviser, confidant and material provider.

Developed is a computer program for the prediction of the aero-acoustic performance characteristics such as discharge pressure, efficiency, power and noise level in the basic design step of axial flow fan. The flow field and the aerodynamic performance of fan are analyzed by using the streamline curvature computing scheme with total pressure loss and flow deviation models. Fan noise is assumed to be generated due to the pressure fluctuations induced by wake vortices of fan blades and to radiate via dipole distribution. The vortex-induced fluctuating pressure on blade surface is calculated by combining thin airfoil theory and the predicted flow field data. The predicted aerodynamic performances, sound pressure level and noise directivity patterns of fan by the present computer program are favorably compared with the test data of actual fan. Furthermore, the present computer program is shown to be very useful in optimizing design variables of fan with high efficiency and low noise level and in analyzing their design sensitivities.
