It was shown in speech production studies that the preparation unit of spoken word production is language particular, such as onset phonemes for English and Dutch, syllables for Mandarin Chinese, and morae for Japanese. However, there have been inconsistent results on whether the onset phoneme is a planning unit of spoken word production in Korean. In this study, two sets of experiments investigated possible influences of task demands on the phonological preparation in native Korean adults, namely, implicit priming and word naming with the form preparation paradigm. Only the word naming task, but not the implicit priming task, showed a significant onset priming effect, even though there were significant syllable priming effects in both tasks. Following the attentional theory ($O^{\prime}S{\acute{e}}aghdha$ & Frazer, 2014), these results suggest that task demands might play a role in the absence/presence of onset priming effects in Korean. Native Korean speakers could maintain their attention to the shared onset phonemes in word naming, which is not very demanding, while they have difficulties in allocating their attention to such units in a more cognitive-demanding implicit priming, even though both tasks involve accessing phonological codes. These findings demonstrate that there are cross-linguistic differences in the first selectable unit in preparation of spoken word production, but within a single language, the preparation unit might not be immutable.

수학 수업에서 핵심적인 역할을 하는 과제의 인지적 수준은 교수${\cdot}$학습 과정 동안 다양하게 변할 수 있다. 이에 본 연구는 4개의 6학년 수학교실에서 '비와 비율' 단원에 제시된 주요 과제들을 대상으로 우리나라 수학교실에서 나타나는 과제 설정과 실행 패턴은 어떠한지, 그리고 그 패턴에 영향을 미치는 교실 요인은 무엇인지 면밀하게 살펴보았다. 분석 결과 초기의 높은 수준의 인지적 과제가 수업 내내 전반적으로 유지되는 경우도 있었으나, 여러 가지 요인에 의해서 의미와 연계되지 않은 절차, 비체계적인 탐구, 불충분한 탐구로 쇠퇴하는 경우도 있었다. 이에 본 연구는 수학 시간에 교사가 특히 주의해야 할 요인을 밝히고, 전반적으로 정적인 의미의 분석보다는 수학적 과제의 인지적 수준이 변화하는 과정에 대한 이해 및 분석의 중요성을 강조한다.

In current study on 8 college students there was examined modulation of eyeblink (as measured by integrated EMG of m.orbicularis oculi) and skin conductance response (SCR) to an acoustic startle probe (85 dB[A] white noise) by attending to task presented in auditory modality (to memorize words for further recognition) and entire performance of the word recognition test. Both eyeblink magnitude and SCR amplitude and rise time to startle probes were modified (larger magnitude of EMG peak, lower amplitude and shorter rise time of SCR) during attending to task as compared to performance on test. Results are interpreted n terms of modification of electrodermal and eyeblink components of startle and orienting reflexes by task characteristics (passive versus active efforts), attentional demands and aversiveness of experimental situation. However, eyeblink startle response manifested potentiation during attending to task, while SCR demonstrated attenuation. There are discussed implications of startle modulatioas a potentially sensitive probe of situational demands in stress research and also are considered prospects for further studies.

It is an important issue to explore classroom environments which are conducive to developing students' mathematical performance. This study explores the effects of different classroom environments (solution-demand and corresponding-time setting) on mathematical performances. Fourteen and eighteen prospective teachers were required to prove a task under different conditions respectively: a) Cognitive demand of multiple-solution corresponding time of three hours, and b) Cognitive demand of a right solution corresponding time of 20 minutes. We used SOLO as the assessment tool for mathematical performance from quality perspective. Significant differences were found in the quantity and quality of mathematical performance. The regular environment focusing on speed and accuracy were found to be directly linked to low levels of performance. The findings above provide implications to the cognitive benefits of multiple-solution demand and corresponding time setting.

본 연구의 목적은 스토리텔링 수학 교과서 개발과 학교 현장에서 스토리텔링 교과서 활용의 방향성을 제시하기 위해, 2009 개정 교육과정에 따른 중학교 2학년 수학 교과서 5종을 연구 대상으로 수학 과제 유형에 따른 인지적 노력 수준, 답안 유형, 스토리텔링 유형을 분석하였다. 연구 결과, 첫째, 수학 과제의 인지적 노력 수준은 공통적으로 모든 교과 내용 영역에서 PNC(Procedures without Connections) 과제가 가장 많은 비중을 차지하였고, 수학적 내용 과제에서는 인지적 노력이 낮은 수준의 과제(Low-Level)가 많았고, 수학적 활동 과제에서는 인지적 노력이 높은 수준의 과제(High-Level)가 더 많았다. 둘째, 학생들에게 요구하는 답안 유형은 모든 영역에서 단답형이 가장 많았고, 수학적 내용 과제의 대부분은 단답형, 수학적 활동 과제는 단답형과 설명형이 많았다. 마지막으로 스토리텔링의 유형은 실생활 연계형이 가장 많은 비중을 차지하고 있었고, 수학적 활동 과제의 수가 수학적 내용 과제의 수보다 휠씬 적었다. 그러나 스토리텔링 유형이 반영된 과제에서는 수학적 활동 과제의 비율이 수학적 내용 과제의 비율보다 더 높았다. 이러한 연구 결과를 바탕으로 향후 다른 학년의 스토리텔링 수학 교과서를 개발하고 학교 현장에 적용할 때, 수학 과제 유형에 따른 인지적 노력 수준, 답안 유형, 스토리텔링 유형에 대해서 균형성과 다양성을 고려해야할 필요성을 제시할 수 있다.

For information processing tasks, it is an important cognitive skill to manipulate and store information, which is known as information intake. One of the tasks which greatly involve this skill would be a spreadsheet calculation task. In this study, a spreadsheet calculation task is analyzed by the cognitive task analysis based on the cognitive factors having been usef for a model of human information processing. By the results of the cognitive task analysis, the spreadsheet calculation tasks to be used in the experiments are designed and the testbattery of cognitive abilities assessment (CCAB ; complex cognitive asssessment battery) are selected. Then, the features of cognitive demands and a human performance model of the spreadsheet calculation task are suggested by means of correlation analysis, principal component factor analysis, and regression analysis of the results of the experiments on task performances and the assessment of cognitive abilities. Also, the application of the results of the study to job placement and further research issues are described.

Apart from the customer demands themselves, the weightings of the customer demands are one of the main input data of a QFD (Quality Function Deployment) and furthermore of the actual construction process of products. Up to now, most interviews with stakeholders have been carried out with questionnaires and then absolute weightings have been used. Now it has been analysed if the use of other interview and evaluation techniques, e.g. relative weightings and Analytic Hierarchy Process (AHP), can improve the precision of the demands and wishes of the stakeholders. Now the task was to analyse if the use of relative weightings as input of a QFD is possible at all, how they have to be adapted and if an increase in precision compared to the use of absolute weightings is reached. When using AHP during the product development it has become clear that only up to seven demands can be rated at the same time by customers. That means that a kind of hierarchy has to be developed to correctly transfer the demands and their weightings into the QFD.

According to software growth, also software maintenance has been continuously improving. In addition, the existing concept of software maintenance process demands operational management and improvement of service task. However, when we perform maintenance task, we have several constraints about applying service based requirement to system. Therefore, in order to solve these problems, we need a study of task of process for service based maintenance. In this paper, we propose a Service based Software Maintenance Process. Proposed process based on MaRMI-RE standard for software development and maintenance and compares it with the service based representative standards. In a related works, we study activity of ITIL and identify activities and tasks for maintenance. After this, identified activities and tasks compare with activities of MaRMI-RE. And then, we derive activities and tasks of a Service based Software Maintenance Process. Finally, we validate a result by comparing the proposed process with a general service operational process.

This study proposed task-based teaming strategies as a means of fulfilling the demands and goals of the 7th national science curriculum. Task-based learning is based on the use of a series of activities whereby a teacher presents students with tasks related to daily lift and the students solve the tasks by themselves using various methods and thought processes and then present and discuss their results with each other. The tasks are selected from the 6-grade science textbook, are reconstructed and are then given to the classes. The tasks include whole class activities as well as individual activities related to the interests, abilities, and concerns of the students. The purpose of this study was to verify the effects of task-based learning classes on the science process skills and the scientific attitudes of elementary school students, when applied to 6th grade students. For this, the task-based learning activities were applied to an experimental group and expository teaching was applied to the comparison group. Both groups were given a pre-post test on science process skills and scientific attitudes. The results indicate that task-based loaming is very effective in the development of science process skills and scientific attitudes.
