While 'Computer self-efficacy' is widely studied In the social science field with regard to the training effectiveness, little research has focused on clarifying the role of 'needs' in relation to self-efficacy and outcome expectations. in this regard, this study investigated the effects of 'needs to learn computer shills,' extending the social cognitive theory. A survey instrument was adopted and modified from previous studies to measure behavioral modeling, prior experience, Perceived computer self-efficacy, Perceived needs to learn computer skills and outcome expectations. A total of 209 practitioners were surveyed in this study. As a result, most part of the social cognitive theory was again Proven to be effective, and the 'needs to learn computer skills' was proven to be significant as a moderating variable between computer self-efficacy and outcome expectations. Implications of the research were discussed, and further studies were suggested at the end.

Now a days many industries and bigger organisation (Indian Railways, Bharat Heavy Electricals Ltd.) are facing difficulties in implementing the new technology because of non-availability of fully trained staff. Also for the employed technical and other staff lot of resistance management has to face to get them trained for adoption of new technology. There are also very less organisations who can design effective training programmes and at the same time develop course material specially multimedia packages and computer base training (CBT) which can satisfy the need of different target groups of industries. Indian Railways was also facing similar situation while implementing the Air Brake System technology In Indian Railways. TTTI Bhopal took that challenge and designed, developed and trained Indian Railways trainer for implementation of the package on different target group. The present paper offers a case study on the same.

EEG-based brain-computer interfaces has focused on explicitly expressed intentions to assist physically impaired patients. For EEG-based-computer interfaces to function effectively, it should be able to understand users' implicit information. Since it is hard to gather EEG signals of human brains, we do not have enough training data which are essential for proper classification performance of implicit intention. In this paper, we improve the subject independent classification of implicit intention through the generation of additional training data. In the first stage, we perform the PCA (principal component analysis) of training data in a bid to remove redundant components in the components within the input data. After the dimension reduction by PCA, we train ICA (independent component analysis) network whose outputs are statistically independent. We can get additional training data by adding Gaussian noises to ICA outputs and projecting them to input data domain. Through simulations with EEG data provided by CNSL, KAIST, we improve the classification performance from 65.05% to 66.69% with Gamma components. The proposed sample generation method can be applied to any machine learning problem with fewer samples.

Existing LDA uses the transform matrix that maximizes distance between classes. So we have to convert from an image to one-dimensional vector as training vector. However, in 2D-LDA, we can directly use two-dimensional image itself as training matrix, so that the classification performance can be enhanced about 20% comparing LDA, since the training matrix preserves the spatial information of two-dimensional image. However 2D-LDA uses same calculation schema for transformation matrix and therefore both LDA and 2D-LDA has the heteroscedastic problem which means that the class classification cannot obtain beneficial information of spatial distances of class clusters since LDA uses only data correlation-based covariance matrix of the training data without any reference to distances between classes. In this paper, we propose a new method to apply training matrix of 2D-LDA by using WPS-LDA idea that calculates the reciprocal of distance between classes and apply this weight to between class scatter matrix. The experimental result shows that the discriminating power of proposed 2D-LDA with weighted between class scatter has been improved up to 2% than original 2D-LDA. This method has good performance, especially when the distance between two classes is very close and the dimension of projection axis is low.

PURPOSE: The purpose of the present study is to investigate the changes in the cognitive function of elderly dementia patients residing in a residential care facility, following six weeks of brain-computer interface (BCI)-based cognitive training and to determine whether BCI-based cognitive training effectively improves their cognitive functions. METHODS: Thirty subjects diagnosed with dementia were randomly assigned to either the experimental or control group. Pre- and post-test cognitive function assessments were conducted using the mini mental state examination-Korean (MMSE-K) and Korean-dementia rating scale (K-DRS). The experimental group received BCI-based cognitive training, which consisted of games such as flying a ball and exploding a bomb, while the control group participated in music listening activities and National Health Gymnastics. Both groups engaged in a total of 18 sessions (3 times per week for 6 weeks, for 40 minutes per session). RESULTS: After 6 weeks of intervention, the experimental group had significantly increased MMSE-K scores ($19.53{\pm}1.30$ to $22.20{\pm}1.15$; p<.0011) and total K-DRS scores ($87.20{\pm}4.16$ to $99.33{\pm}1.15$; p<.0011). In addition, the experimental group showed greater cognitive improvements than the control group. CONCLUSION: The results of this study suggest that BCI-based cognitive training is a positive intervention tool for improving the cognitive function of dementia patients.

Purpose The purpose of this study is to investigate the factors that affect the user satisfaction and continuous use intention of the improved ATCIS in the Korean Army. Design/methodology/approach Based on the various theories in relation to IT continuance, user satisfaction was identified as the main factor with regard to the continuous use intention of the improved ATCIS. In addition, computer self-efficacy, education-training, and system quality were hypothesized as antecedent variables to user satisfaction, and information security stress was set as a moderating variable for these relationships. Findings Survey results show that computer self-efficacy, education and training, and system quality had a positive effect on user satisfaction, and information security stress was found to moderate these relationships. The effects of computer self-efficacy and education-training on user satisfaction were higher in the group with low information security stress. However, the relationship between system quality and user satisfaction was higher in the group with high information security stress. User satisfaction is found to have a positive effect on the continuous use intention even with habit considered as a control variable.

이 연구는 교원 정보화 역량강화 연수과정 내용 및 운영에 대한 현황조사 및 연수과정에 대한 온라인 설문조사, 연수과정 운영자 심층면담 등을 토대로 기존 교원 정보화 역량강화 연수의 운영 성과를 분석한 것이다. 이 연구를 바탕으로 차세대 교원 정보화 연수개발을 위한 현 연수과정의 개선방안을 제시하였다. 온라인 설문조사 결과에 따르면, 현행 교원 정보화 역량강화 연수과정은 전체적으로 바람직하게 운영되고 있다고 볼 수 있다. 다만, '사고력 신장을 위한 ICT활용 교육 과정', '미래로 가는 교육 과정', 'ICT활용 문제중심학습 과정'과 같이 보통수준이라고 응답한 비율이 비교적 높은 과정에 대해서는 운영과정의 효과성과 효율성 제고를 위한 노력이 요구된다. 특히 목표의 실천가능성, 수준별 고려여부, 연수 장소 및 교통편 등의 접근성, 맞춤형 수준별 전략 등의 하위평가영역은 타 영역에 비해 낮게 평가되었다. 또한 교원 정보화 역량강화 연수운영자에 대한 심층면담 결과, 이들은 교육현장 요구반영에의 필요성, 강사 재훈련 및 자기계발기회 제공, 지역 전달 연수의 질 관리, 해외 연수사례 국내화 과정에서 특성화, 연수기간의 확대, 연수 후 후속지원의 필요성 등을 제안하였다.
