연구는 Random Matrix Theory(RMT)방법에 의하여 분해된 상관행렬이 원래 주식간 상호작용을 충분히 반영하고 있는지 여부를 Mantegna(1999)에 의하여 제안된 주식 네트워크와 실증적으로 결합 검증하였다. 분석결과에 의하면, RMT 방법으로 분해된 상관행렬을 주식 네트워크와 결합하였을 때, 분해된 상관행렬은 주식간 상호작용에서 의미 있는 요인들의 속성을 적절히 반영하고 있다는 것을 실증적으로 확인할 수 있었다. 이러한 결과를 통하여, 주식간 상호작용을 계량화한 상관행렬을 RMT방법에 의하여 특정 속성을 갖는 상관행렬로...

self-efficacy with the commitment of preschool teachers in the state of Selangor in addition to testing emotional competence and self-efficacy as predictor factors to teacher commitment. This study is based on the Emotional Competence Theory developed by Goleman (2001), the Self-efficacy Model by Tschannen-Moran & Hoy (2001) and Teacher Commitment Model by Thien et al. (2014). This is a survey study involved 428 samples in Selangor through cluster and systematic random sampling method to answer...

a questionnaire was developed based on the established transition theory. The validation of the theory was analyzed through structural equation modeling (SEM), and a multi-group analysis was conducted to find out what differences existed in the structural model for dormitory, self-catering, and commuting to school. As a result of the qualitative study, 112 concepts, 34 subcategories, and 9 categories were derived from open coding. As a result of the quantitative analysis through SEM, first, the...

In this work, the effects of maleic anhydride (MA) content on mechanical properties of chopped carbon fibers (CFs)-reinforced MA-grafted-polypropylene (MAPP) matrix composites. A direct oxyfluorination on CF surfaces was applied to increase the interfacial strength between the CFs and MAPP matrix. The mechanical properties of the CFs/MAPP composites are likely to be different in terms of MA content. Surface characteristics were observed by scanning electron microscope, Fourier transform infrared...

with continuous carbon fibers for two levels of fiber-matrix adhesion was performed. A carbon fiber with commercial sizing was used and also treated with a known silane, (3-glycidoxy propyl trimethoxysilane) coupling agent. Toughness was determined using the double cantilever test, together with surface analysis after failure using scanning electron microscope. The presence of polysulfone particles improved the fracture behavior of the composite, but fiber-matrix adhesion seemed to play a very...

by optical and scanning electron microscopic observations. The results were compared with a phenolic matrix composite counterpart prepared without xGnP. The flexural properties and interlaminar shear strength of the xGnP-coated carbon fiber/phenolic matrix composites were found to be higher than those of the uncoated composite. The flexural and interlaminar shear strengths were affected by the particle size of the xGnP, while the particle size had no significant effect on the flexural modulus. I...

Second, it can be seen that the network structure for each period gradually changes from the first to the third periods. This demonstrated that while the research of theory of mind was somewhat slow but steadily active, the keywords identified in the early childhood theory of mind study evolved into a broad and rich array. Based on the results of this study, this study suggests diversification of the theory of mind research to perspectives of social cognition development of young children.
