There is a growing interest in the education of gifted children nation-wide. The present study was performed to find out characteristics of students who are receiving special education as gifted using a new psychological inventory which measures the temperament and charcter separately. We compared students who have been selected for their trlent in math and science with students who do well academically. Academic competence was operationally defined by grades or by IQ. Gifted children are usually thought to be characterized by an innate ability, and it was expected that there would be some difference between temperaments of the gifted group and those of the academically competent group. However, there was no significant difference between the two groups not only in their temperaments, but also in other sub-scales of character. This result suggests that in spite of the extensive effort and cost involved in the selection process, the children who are currently selected as gifted show no distinction when compared to academically competent students. Based on the results some practical suggestions were made in order to improve the selection of the gifted children.

This paper aims to develop and validate a situational judgement test to diagnose the Competencey of public ethics for undergraduates. A criterion group composing of high performers was formed. Critical incidents and responses were developed from interviews with members of the criterion group. Also an expert committee was composed of six university members who have professional knowledge and experience on Competencey based selection or education. This committee reviewed all the items developed and selected some of them for the final test. Item validity and reliability were examined through the final test that 519 college students took. The result of the confirmatory as well as exploratory factor analysis showed that the Competencey of public ethics consisted of 2 sub-elements which were work ethics and democratic citizenship. The correlation between results of the test and the HEXACO model was statistically significant. Overall, the findings of the study highlight that a situational judgement test can be developed and utilized to diagnose Competencey levels of public ethics for undergraduates.

In this paper, the educational effects of NETCLASS(network-based collaborative learning system) for EICE(education on information communication ethics) were verified by a non-equivalent control group protest-posttest design. We experimented our system on an experimental group (45 learners) and a comparative group (45 learners) respectively with a defining issues test (DIT). The t-value is 5.108 which shows the difference of the mean value between the experimental group and the comparative group, and their average p-mark shows that the difference is statistically meaningful at p<.001 level. Thus, the experiment using NETCLASS and DIT suggests that the morality of the experimental group is higher than that of the comparative group(t(88)=+5.108, p<.001). This paper suggests very strong possibility that the abilities such as creativity, sociality, morality and emotivity can be improved by utilizing ICT(Information and Communication Technology).

Objective : The purpose of this study was to analyze the effects of simultaneous dual-task training to assess executive function in older adults. Methods : We searched the PubMed, EMBASE, Cochrane, Web of Science, and RISS databases of publicated studies in the past decade. Seven studies were selected based on the inclusion and exclusion criteria. Qualitative assessment and meta-analysis were performed for the seven studies. Results : A randomized controlled trial design was used in the selected studies, and PEDro Scores above seven were obtained. The Trial Making Test (TMT) evaluated the effects of dual-task training on executive function in four studies. The Color Trail Test (CTT) was used in two studies, and Stroop test was used in three studies. The effect size for total executive function was 0.38, which was small. The effect sizes for TMT and CTT were 0.37. Stroop Test was 0.34, demonstrating that their effect sizes were also small. Only significant effects in total executive function, TMT, and CTT showed significant effects (all p<0.05). Conclusion : This study confirmed that dual-task training was effective in improving executive function in older adults. To improve the effectiveness of dual-task training, the difficulty of the dual-task training should be considered. It is also necessary to implement assessments that can evaluate performance under dual-task conditions as well as conventional test tools for executive function. In the future, dual-task training could be used as an appropriate intervention for executive function in older adults to delay the onset of dementia.

Objective : The purpose of this study was to identify Effects of the ROM dance on cognitive function, neuropsychiatric in using wheelchair senior in nursing home. Methods : The subjects of the experimental group were 15 seniors using wheelchair who attended an ROM dance program in a nursing home. It was carried out for 18 weeks from Mar. 2010. to August. 2010. The evaluation tools used for the presented study were the Mini-Mental Status Exam-Korean(MMSE-K) and Neuropsychiatric Inventory-Questionaire (NPI-Q). Results : In the terms of cognitive function there was no significant defference between the mean pre/post test. but the factor(orientation of time) of MMSE-K and the factors 2 (sleep/nighttime behavios, apathy/indefference) of NPI-Q was significant improvement. Conclusion : In this study, the ROM dance program was effective in improving cognitive function and neuropsychiatric in seniors using wheelchair. also ROM dance program was decreasing and regression delay effect in cognitive and neuropsychiatric.

This paper solves Push-Push game with the model checker NuSMY which exhaustively explores all search space to determine whether a model satisfies a property. In case a model doesn't satisfy properties to be checked, NuSMV generates a counterexample which tells where this unsatisfaction occurs. However, the algorithm for generating counterexample in NuSMV traverses a search space twice so that it is inefficient for solving the game we consider here. To save the time to be required to complete the game, we revise the part of counterexample generation so that it traverses a search space once. As a result, we obtain 62% time improvement and 11% space improvement in solving the game with modified NuSMV.

영상으로 콘텐츠를 개발하는 사람들을 '크리에이터'라 칭한다. 이들이 사람들에게 재미를 주고 이목을 끌기 위해 표준어 이외에 다양한 유행어와 신조어들을 만들어내며 이들을 영상뿐만 아니라 자막으로 활용하게 된다. 이러한 자막이 있는 영상 제작시 대본을 제작하는데 있어 자유도가 높은 크리에이터들의 특징상 맞춤법 오류 및 오타의 문제가 생긴다. 하지만 영상제작 도구에는 맞춤법 검사 기능이 없어 검사를 미리 하기에는 어려운 점이 있다. 우리는 이 문제점을 해결하기 위해 영상을 완성 하고 최종 검토를 할 때 맞춤법 검사를 하기 쉽도록 프로그램을 개발한다. OpenCV를 통해 영상의 자막을 글자로써 인식을 하고, fastText 모델을 통해 인식된 글자가 맞춤법에 맞는지 크리에이터에게 제안해주는 맞춤형 프로그램을 개발하고자 한다.

Objective : This study aimed to develop a Comprehensive Oro-Facial Function Scale (COFFS) that can evaluate oro-facial function in patients with dysphagia. Methods : To verify the item composition and reliability of the COFFS, preliminary items were collected by selecting and analyzing four previous studies, and the Content Validity Ratio (CVR) was derived through a second survey of experts. Cronbach's 𝛼 was calculated for the internal validity of the evaluation items, and the test-retest reliability and inter-rater reliability were calculated using the internal classification coefficients (ICC). Results : The content validity ratio of all items was 0.67; in the case of Cronbach's 𝛼 value for each domain, 0.849 for communication domain, -0.224 for the oro-facial structure and shape, 0.831 for the ability to perform orofacial movements, and 0.946 for mastication and swallowing function. The test-retest reliability was 0.974 and the inter-rater reliability was 0.937, showing high reliability. Conclusion : In this study, the evaluation tool of COFFS was finally selected from 34 items in four areas and developed on a 3-5 point scale according to the evaluation items. In future studies, additional research is needed to prove its validity through correlation with other evaluation tools that measure oro-facial function.
