대한치과교정학회 The Korean Journal of Orthodontics 2018, 제 48권 제 5호 6 326-332 (7 pages)
Objective: This study was performed to compare the perception of pain between patients treated with passive self-ligating fixed appliances and those treated with Invisalign aligners. Methods: This prospective study conducted in Saudi Arabia used an estimated sample of 64 patients from a private dental clinic. After obtaining written informed consent, the patients were divided into two groups; one group (n = 32) was treated using passive self-ligating fixed appliances and the other group (n = 32)... -

Although 3D-complex fractionated atrial electrogram (CFAE) mapping is useful in radiofrequency catheter ablation for persistent atrial fibrillation (AF), the directions and configuration of the bipolar electrodes may affect the electrogram. This study aimed to compare the spatial reproducibility of CFAE by changing the catheter orientations and electrode distance in an in -silico left atrium (LA). We conducted this study by importing the heart CT image of a patient with AF into a 3D-homogeneous... -
A Study on the Effects of Parental Involvement on Academic Achievement
Eom Moonyoung, Jung Sungsoo, Son Eunae 경인교육대학교 교육연구원 교육논총 19 Pages
경인교육대학교 교육연구원 교육논총 제 41권 특별호 5 83-101 (19 pages)
This study analyzes the effects of the type of parental involvement on students academic achievement based on the Asian culture of education, which is widely recognized as being different to the Western culture of education. Based on the research assumption, Progress in International Reading Literacy Study (PIRLS) 2006 data are utilized for the analysis. Using two-level hierarchical linear modeling (HLM), this study s three main results related to the research questions are: First, home-based... -

수중에서 음원까지의 거리를 추정하는 방법들이 연구되어 왔다. 그 가운데 초점 빔 형성기를 사용한 거리 추정 기법은 낮은 신호대 잡음비를 갖는 환경에서 우수한 성능을 갖는 것으고 알려져 있으나 다중 음원 환경에서는 성능 저하가 초래된다. 이에 본 논문에서는 두 개의 초점 빔 형성기를 사용하여 거리를 추정하는 방법을 제안하였다. 또한 표본화 주파수가 낮으면 초점 빔 형성기를 정확하게 원하는 위치로 지향할 수 없기 때문에 빔 패턴의 왜곡이 발생하게 되고, 그 결과 거리 추정 기법의 성능 저하를 초래한다. 그리고 이... -

한국청각언어재활학회 Audiology and Speech Research 2017, 제 13권 제 2호 1 95-100 (6 pages)
Purpose: Although many previous literatures investigated various outcomes of hearing aid fitting, a few studies explored the cost-effectiveness of hearing aid fitting and its underlying model. Examining cost effectiveness of hearing aid fitting provides comparative values of hearing aid fitting by measuring the economic gains of hearing aid interventions. The purpose of present study is to understand the cost-related outcomes and benefits of hearing aid uses and provide economic insights of...
