The effects of coping on physical and psychosocial adaptation in the 297 patients with rheumatoid arthritis were investigated. The coping methods were divided into compliance of medical regimens, self-control activities, and cognitive control. The effects of these coping methods was analyzed with stepwise regression. The physical adaptation is found to be significantly affected by cognitive control, self-control activities, and compliance of medical regimens in order Compliance of the medical regimens affects negatively the physical adaptation. And psychosocial adaptation is significantly affected by the cognitive control. The analysis of these results by illness duration showed the distinct differences. That is in the patients who experienced the disease less than 48 months, the physical and the psychosocial adaptation were significantly affected only by the cognitive control. But in the patients who experienced the disease more than 96 months, the physical and the psychosocial adaptation were significantly affected by self-control activities. Based upon these results, it is recommended that the nurses who care the newly diagnosed patients emphasize on the positive side of the state. And the patients who are diagnosed long ago need the nursing programs which teach and promote self-control activities. Also it is suggested that the results of compliance must be considered rather than as the result variable.

The purpose of this study is to investigate the effect of computerized cognitive therapy on cognitive function and Instrumental Activities of Daily Living for elderly people with mild cognitive impairment living in the community. 22 MCI elderly people were randomly assigned to 11 experimental group and 11 control group. For a total of 10 weeks, 3 times a week, 30 minutes per session, the experimental group received CoTras and the control group received traditional cognitive rehabilitation. Neurobehavioral Cognitive Status Examination(NCSE) and Korean Instrumental Activities of Daily Living(K-IADL) were used to investigate the changes in cognitive function and performance of instrumental activities of daily living before and after the intervention. As a result of the study, the experimental group showed improvement in overall cognitive function, including attention and memory, and performance in IADL. The use of CoTras may be considered to improve cognitive function and performance of instrumental activities of daily living for the elderly with mild cognitive impairment in the community.

Power allocation is an important factor for cognitive radio networks to achieve higher communication capacity and faster equilibrium. This paper considers power allocation problem to each cognitive user to maximize capacity of the cognitive systems subject to the constraints on the total power of each cognitive user and the interference levels of the primary user. Since this power control problem can be formulated as a mixed-integer nonlinear programming (NP) equivalent to variational inequality (VI) problem in convex polyhedron which can be transformed into complementary problem (CP), we utilize modified projection method to solve this CP problem instead of finding NP solution and give a power control allocation algorithm with a subcarrier allocation scheme. Simulation results show that the proposed algorithm performs well and effectively reduces the system power consumption with almost maximum capacity while achieve Nash equilibrium.

This study is a randomized pretest-posttest design that aims to investigate the effect of early entrepreneurship education on cognitive and non- early entrepreneurship education, non-cognitive skills, creativity, self-efficacy, Bizworld cognitive skills of male sixth-grade primary school students. A total of 45 students were selected by multi-stage random sampling method and were assigned randomly to experimental, active-control and control groups. The experimental group received entrepreneurship education based on the Bizworld entrepreneurship program. The results indicate that early entrepreneurship education had an effect on non-cognitive skills (such as risk taking propensity, creativity, self-efficacy, persistence and need for achievement. It seems that early entrepreneurship education is a proper strategy to develop children's non-cognitive skills in late years of primary school. These skills will affect children's individual, educational, social and occupational future and can have long term benefits for students, families and society.

Recently effective spectrum resource technologies have been studied using a game theorectical approach for cognitive radio networks. Radio resource management is required an effective scheme because the performance of a radio communication system much depends on it's effectiveness. In this paper, we suggest a game theoretical algorithm for adaptive power control which is required an effect scheme in cognitive radio networks. It will be a distributed network. In the network distributed cognitive radio secondary users require an adaptive power control. There are many results which are suggested some possibility of game theoretical approaches for communication resource sharing. However, we suggest a practical game algorithm to achieve Nash equilibrium of all secondary users using a Nash equilibrium theorem in this paper. Particularly, a game model was analyzed for adaptive power control of a cognitive radio network, which is involved in DSSS (Direct Sequence Spread Spectrum) techniques. In case of K=63 and N=12 in the DSSS network, the number of iteration was less than maximum 200 using the suggested algorithm.

This study purposed to examine the effects of the Feuerstein's cognitive mediated learning for gifted children on attention control and attention shift. For the study, 40 gifted students were chosen from the 3rd graders in elementary schools and divided into test and control groups using K-WISC-III and Torrance Tests of Creative Thinking. The mediated learning program that is targeted to improve the executive functions of gifted children has used the tools of Organization of Dots, Analytic Perception and Comparisons among Feuerstein's Instrumental Enrichment(FIE). According to the results of this study, a significant improvement has been observed in selective attention, self-control, sustained attention, and attention shift through cognitive mediated learning. Therefore, it has been proven that the cognitive mediated learning is effective in reducing gifted children's problematic behaviors that are caused by a lack of attention control and attention shift and improving their cognitive functions and potentials.
