  • The purpose of this stud)r was to critically review the trends of research methodologies of environmental education. We analyzed Journal of Korean Society for Environmental Education (vol. 1 ∼vol. 14(1)) and The Journal of Environmental Education(vol. 25∼vol. 31) to investigate the trends of methodology in EE research of Korean and other countries and to explore the tasks of it. The findings were as follows, 1) More than half of the character of the papers in Korea were actual condition (54.38%), substitute proposal (32.12%), and the papers in others countries were actual condition (39.35%), substitute proposal (33.55%). 2) The major parts of the method of the papers in Korea were literature review (26.05%), survey research (23.79%), on the other hand the papers in other counties were survey research (42.70%), literature review (25.84%). The results indicated that the research methodologies of environmental education in Korea were needed to be reinforced in the field of qualitative and quantitative research methods.

  • 담화분석은 치매환자의 발화특성을 알아보거나, 환자군을 변별하는 데 있어서 그 효용성이 입증되었다. 그러나 기존의 담화연구들에서 활용된 과제, 전사법, 측정요인들이 서로 상이하므로, 체계적이고 일관적인 분석이 이루어지지 않아 해석을 도출하는데 어려움이 있다. 본 연구는 치매환자의 담화과제, 전사법, 측정요인들을 조사하여 향후 담화분석에 도움이 되고자 하는 목적으로 수행되었다. 이에, 스코퍼스(Scopus) 데이터베이스를 통해 2005년부터 2014년도까지 치매 환자의 담화를 분석한 연구들이 조사되었다. 그 결과, 첫째, 치매환자를 대상으로 가장 많이 쓰인 담화과제는 '주제에 대해 이야기하기'이었다. 둘째, 전사과정에서 일관된 전사규약(transcription conventions)을 적용하는 경우, 좀 더 신뢰성 있는 전사자료를 얻을 수 있었다. 셋째, 담화측정요인들은 담화처리모델에 따라 통일성, 응집성, 생산성, 명제 통사 사전분석, 유창성의 영역들로 범주화되며, 각 범주는 담화처리단계(즉, 개념형성단계, 명제처리단계, 자연언어단계)에 속하였다. 결론적으로, 향후의 담화연구는 치매유형 및 특징에 따라 담화과제를 선정하고, 분석의 신뢰성을 위해 일관된 전사규약을 적용해야 할 것이다. 또한, 담화처리이론에 바탕을 둔 측정을 통해, 담화연구의 해석이 체계적으로 이루어지는 것이 바람직하다고 할 수 있다.

  • This study aimed to investigate the effect of differing heel heights on the electromyographic (EMG) activity in vastus medialis (VM) and vastus lateralis (VL) during stair ascending and descending activities. A total of 26 healthy women volunteered to perform stair-ascending and stair-descending tasks with 3 heel heights: barefoot, 3 cm, and 7 cm. The EMG activities of the VM and VL were recorded during the tasks. During the stair ascending and descending tasks, the EMG activities of both VM and VL significantly changed with differing the heel heights (p<.05). Moreover, the EMG activities of VM and VL during the stair ascending task were significantly higher than the corresponding values during the stair-descending task (p<.05). However, there were no significant differences between the VM:VL EMG ratios for the 3 heel heights (p>.05). The VM:VL EMG ratios between the 2 tasks differed significantly in the 7 cm high heel condition (p<.05). Despite an increase in the EMG activities in both VM and VL during stair ascending and descending tasks, there was no change in the relative EMG intensities of VM and VL, which was measured by calculating the VM:VL ratio this result indicates that no VM:VL imbalances were elicited. The relative EMG intensities of VM and VL during stair descent were lower than the corresponding values during the ascent, suggesting that VM and VL may show an imbalance in the eccentric activation during the weight-acceptance phase. This study provides useful information that will facilitate future research on how heel height affects muscle activity around the knee joint.

  • Textbooks play a very important role as a medium for implementing curriculum in the school. This study aims to analyze tasks for mathematical competencies in the high school 'mathematics' textbooks based on the 2015 revised mathematics curriculum emphasizing competencies. And our study is based on the following two research question. 1. What is the relationship between core competencies and mathematical competencies? 2. What is the distribution of competencies of tasks for mathematical competencies presented in the textbooks? 3. How does the tasks for mathematical competencies reflect the meaning of the mathematical competencies? For this study, the tasks, marked mathematical competencies, were analyzed by elements of each mathematical competencies based on those concept proposed by basic research for the development of the latest mathematics curriculum. The implications of the study are as follows. First, it is necessary to make efforts to strengthen the connection with core competencies while making the most of characteristics of subject(mathematics). Second, it needs to refine the textbook authorization standards, and it should be utilized as an opportunity to improve the textbook. Third, in order to realize competencies-centered education in the school, there should be development of teaching and learning materials that can be used directly.

  • IT outsourcing providers has been expanded from a single functional system to the entire IT service to gain sustainable competitiveness. This new trend of IT outsourcing need outsourcing management capability based on a firm's core capacity. Hiring external IT service providers to manage part or all of its information-related services helps a firm focus on its core business and provides better services to its clients, thus obtaining sustainable competitive advantage. This research investigates the major factors that determine the level of a particular firm's success at IT outsourcing. Based on process innovation and core-competency theories, we identify three significant components of a firm's IT outsourcing management method (ITOMM): level of core-competency-based management, maturity of outsourced tasks, and maturity of outsourcing management. Comprehensive data collection was conducted through an outsourcing association. The survey data were analyzed using a structural analysis method. Maturity of outsourced tasks and maturity of outsourcing management were found to affect project performance directly, while level of core-competency-based management only indirectly impacted project performance through its positive impact on the other two ITOMM components.

  • This paper explores new techniques that are based on a hidden-layer linear transformation for fast speaker adaptation used in deep neural networks (DNNs). Conventional methods using affine transformations are ineffective because they require a relatively large number of parameters to perform. Meanwhile, methods that employ singular-value decomposition (SVD) are utilized because they are effective at reducing adaptive parameters. However, a matrix decomposition is computationally expensive when using online services. We propose the use of an extended diagonal linear transformation method to minimize adaptation parameters without SVD to increase the performance level for tasks that require smaller degrees of adaptation. In Korean large vocabulary continuous speech recognition (LVCSR) tasks, the proposed method shows significant improvements with error-reduction rates of 8.4% and 17.1% in five and 50 conversational sentence adaptations, respectively. Compared with the adaptation methods using SVD, there is an increased recognition performance with fewer parameters.

  • 본 연구의 목적은 초등학교 수학과 교수학습에서 창의성 신장을 위하여 초등학교 교실에서 활용이 가능한 수학 과제의 유형을 분류하여 제시하는 것이다. 본 연구에서는 창의성이 풍부한 과제의 제시를 학생들의 창의적 사고를 신장시키는데 가장 중요한 부분의 하나로 보고 창의성 신장을 위한 과제의 특성과 이들을 유형별로 분류하였다. 이를 위해 그 동안 창의성과 관련하여 연구되어 온 논문과 자료들을 분석하기 위하여 미국 조지아대학의 GIL과 국내의 논문 탐색을 통하여 창의성 관련 자료를 추출하여 분석하였다. 분석 결과 수학 과제를 창의성의 요소인 독창성, 융통성, 유창성, 정교성, 민감성의 5가지의 속성을 포함하는 4가지 표현 방식에 16과제의 유형으로 분류할 수 있었다. 그리고 과제 유형과 함께 학생들의 창의성 신장을 효과적으로 돕기 위해 고려해야 할 사항들을 제안을 하였다.
