  • Network-on-chip (NoC) has evolved to overcome the issues of traditional bus-based on-chip interconnect. In NoC-reuse as TAM, the test schedulers are constrained with the topological position of cores and test access points, which may negatively affect the test time. This paper presents a scalable hybrid test data transportation scheme that allows to simultaneously test multiple heterogeneous cores of NoC-based SoCs, while reusing NoC as TAM. In the proposed test scheme, single test stimuli set of multiple CUTs is embedded into each flit of the test stimuli packets and those packets are multicast to the targeted CUTs. However, the test response packets of each CUT are unicast towards the tester. To reduce network load, a flit is filled with maximum possible test response sets before unicasting towards the tester. With the aid of Verilog and analytical simulations, the proposed scheme is proved effective and the results are compared with some recent techniques.

  • The purpose of this study was to examine the effect of parenting behavior and parent-child communication on elementary school children's multiple intelligence. 321 children selected from two elementary schools and their mothers participated in the study. Data were collected using the multiple intelligence index, parenting behavior inventory and parent-child communication index. The data were statistically analyzed using the t-test, one-way ANOVA(Duncan test), and multiple regression analysis. The study showed that there were some significant differences in children's multiple intelligence according to the children's gender, income, mother and father's educational background. There were some significant differences in children's multiple intelligence according to the parenting behavior, warmth acceptance and permissiveness nonintervention behaviors, and to the parent-child open communication and problematic communication. It was also found that children's gender, family income, warmth acceptance behavior, permissiveness nonintervention behavior, open communication and problematic communication were all significant predictors of the children's multiple intelligence. Implications based on this study are as follows; in order to increase the children' multiple intelligence, parents should be warmer and more accepting and have open communication with their children.

  • Objectives: The purpose of the study is to investigate the relationships between multiple intelligence, academic self-efficacy, satisfaction with major in dental hygiene students. Methods: A self-reported questionnaire was filled out by 490 dental hygiene students in Jeonbuk from March to April, 2015. The questionnaire consisted of 119 questions of multiple intelligences, 28 questions of academic self-efficacy, 5 questions of satisfaction with major by Likert 5 scale. Data were analyzed by descriptive statistics, Pearson's correlation test, and stepwise multiple regression test using SPSS 18.0 program. Results: The students had the highest score in interpersonal intelligence(3.57) and the lowest in naturalist intelligence(2.66). There was a positive correlation between the multiple intelligences, academic self-efficacy and satisfaction with major(p<0.05). The impact of multiple intelligences on academic self-efficacy was influenced by logical-mathematical intelligence, intrapersonal intelligence, musical intelligence, bodily-kinesthetic intelligence, and linguistic intelligence(p<0.05). The variables that had an impact on multiple intelligences and satisfaction with major were interpersonal intelligence and intrapersonal intelligence(p<0.01). Conclusions: The development of multiple intelligences can enhance the satisfaction with the major, quality of education, academic self-efficacy in the dental hygiene students.

  • This study examines the relationships between elementary school students' multiple intelligences, prosocial behaviors, and school adjustments. The sample included 367 students from two elementary schools, and data were collected using the multiple-intelligence index, the prosocial behavior inventory, and the school adjustment index. A statistical analysis was conducted using t-test, a one-way ANOVA (Duncan's test), and a multiple regression analysis. According to the results, there were significant differences in the students' prosocial behaviors according to their multiple intelligences in terms of their sharing, kindness, cooperation, help, sympathy, and protection. In addition, there were significant differences in their school adjustments according to their multiple intelligence in terms of their adjustments to their teachers, friends, studies, and rules and events. The students' multiple intelligence was a significant predictors of their prosocial behaviors and school adjustments. In particular, their interpersonal intelligences, intrapersonal intelligences, and linguistic intelligences were significant predictors of their prosocial behaviors and school adjustments. These results suggest that elementary school students should be encouraged to develop their multiple intelligence to facilitate their prosocial behaviors and school adjustments.

  • 이 연구는 과잉효능감과 과잉확신이 선다형과 서답형 평가에서 어떻게 나타나는지에 조사하였다. 이 연구를 위하여 204명의 여자중학교 학생들이 참여하였다. 선다형과 서답형으로 된 광합성 개념에 대한 검사도구를 사용하였으며, 각 문항마다 자신의 효능감과 확신을 척도로 나타나게 하였다. 연구결과 선다형과 서답형의 상관관계는 0.5가 채 되지 않았으며, 학생들이 생각하는 자신의 문제 해결 능력(효능감)과 실제 능력 간의 상관관계 역시 0.45가 되지 않았다. 학생들은 선다형 문제 해결 과정에서 지식에 대한 확신을 높이는 경향을 보였다. 선다형 문항을 먼저 수행한 집단에서는 그렇지 않은 집단에 비하여 과잉효능감과 과잉확신의 비율이 더 높게 나타났다. 이 연구 결과는 학생들을 평가하는 과정에서 서답형의 사용을 늘릴 것을 제언한다. 또한 두 형태의 검사도구를 동시에 사용하게 될 경우 선다형 검사도구를 사후에 사용하여 학생들이 적절한 수준의 효능감과 확신을 유지할 수 있도록 해야 될 것이다.

  • 이 연구는 기존의 다중지능 검사의 문제점을 극복하고, H. Gardner의 다중지능에 관한 심리측정 원리들을 반영하여 개발한 한국형 다중지능 진단도구의 타당화 연구이다. 검사는 유아용, 초등학교 저학년용, 초등학교 고학년용, 중학생용, 고등학생용, 총 5종의 검사로 구성되었고, 검사의 형식은 검사시행 시점까지의 성취를 재는 선택형 문항, 능력을 재는 진위문항, 능력과 흥미를 재는 자기보고식 리커르트 척도 문항의 3가지 형식으로 구성하였다. H. Gardner의 심리측정에 대한 제언에 따라, 지능의 핵심요소에 대한 재검토, 지능들 간의 중복성 및 위계성 여부에 대한 검토, 지능 간 편파적이지 않은 문항 구성, 검사형식의 다양화 등을 지향했고, 특히 본 검사에서는 능력과 흥미와 성취를 포괄적으로 측정하고자 했다. 1, 2차 예비검사와 본검사를 통해 최종 표준화검사를 제작했고, 총 5585명의 연구대상을 연령별, 성별, 지역별로 구분하여 표집하고, 이를 통해 규준점수를 추출하여, 연령별 상대적 비교를 할 수 있도록 하였다. 검사의 타당화를 위하여, 수검행동 관찰, 평균, 표준편차, 정답률, 신뢰도, 하위지능검사들 간의 상관, 지능별 진로선택의 평균순위에 대한 Kruskal-Wallis 검증 등의 분석을 하였다. 하위지능 간 상관분석 결과, 본 검사는 지능 간 독립성 가정을 지지했고, 지능별 진로선택에 관한 비모수 통계검증 결과, 다중지능이 진로선택의 계열과 대체로 관련이 있음을 확인할 수 있었다. 본 연구는 언어와 논리수학 능력에 유리하던 종래의 검사들과 달리, 지능별로 문항이 공평하도록 노력했고, 객관화할 수 있는 능력문항과 규준점수를 개발한 것, 능력과 흥미와 성취 점수들 간의 비교를 통한 교육적 처방 및 상담을 위한 방편을 마련한 것에서 시사점을 찾을 수 있다. 그러나 검사시행의 현실적인 제약으로 문항수가 적게 개발되어, 요인분석이나 서로 다른 형식의 검사간의 상관분석 등을 하지 못한 데에는 한계가 있다. 따라서 향후 문항 수를 늘려 전체 검사를 두 차례로 나누어 시행하는 연구를 하면 요인분석 및 기타 여러 타당화 증거들을 보완할 수 있을 것이다.

  • In genetic association studies with high-dimensional genomic data, multiple group testing procedures are often required in order to identify disease/trait-related genes or genetic regions, where multiple genetic sites or variants are located within the same gene or genetic region. However, statistical testing procedures based on an individual test suffer from multiple testing issues such as the control of family-wise error rate and dependent tests. Moreover, detecting only a few of genes associated with a phenotype outcome among tens of thousands of genes is of main interest in genetic association studies. In this reason regularization procedures, where a phenotype outcome regresses on all genomic markers and then regression coefficients are estimated based on a penalized likelihood, have been considered as a good alternative approach to analysis of high-dimensional genomic data. But, selection performance of regularization procedures has been rarely compared with that of statistical group testing procedures. In this article, we performed extensive simulation studies where commonly used group testing procedures such as principal component analysis, Hotelling's $T^2$ test, and permutation test are compared with group lasso (least absolute selection and shrinkage operator) in terms of true positive selection. Also, we applied all methods considered in simulation studies to identify genes associated with ovarian cancer from over 20,000 genetic sites generated from Illumina Infinium HumanMethylation27K Beadchip. We found a big discrepancy of selected genes between multiple group testing procedures and group lasso.

  • The cental magnetic field of an HTS magnet consisting of pancake windings can be increased if the magnet is excited by multiple power sources. Multiple power sources enable all pancake windings to conduct their critical currents. The HTS magnet consisting of pancake windings was excited by separate power sources in this paper. Critical currents of each pancake winding were determined by using optimization technique. Fabrication of the BSCCO magnet consisting of 10 pancake windings is described and test results of the BSCCO magnet are given. Central magnetic field and perpendicular magnetic field of the magnet excited by multiple power sources were compared with those of the magnet excited by a single power source.
