In this paper, we explore a richer sense of finger gnosis (finger knowledge) with respect to three- and four-year-olds’ interactions with a novel iPad application (TouchCounts), focusing on their responses to an “inverse subitising” task. The direct and tactile nature of their engagement with TouchCounts leads to a striking shift from incrementing using the index finger to deployment of several fingers all-at-once (in a cardinal touch gesture) to achieve a given target number that is then...

A developmental view of child development with its biological imperatives has been extensively critiqued over the years and found to be wanting from a range of cultural (Rogoff, 2003; Howes, 2010), social (Qvortrup, Corsaro & Honig, 2009) and even health (Bendelow, 2009; Rogoff, 2011) reasons. But what has been missing from these debates has been a theoretically robust presentation of another way of conceptualizing children’s development (Hedegaard & Fleer, 2013). In drawing upon...

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...

본 연구의 목적은 그간 혼용되어 왔던 commitment와 flow, 운동중독과의 관계를 정량화된 방법으로 규명하는데 그 목적이 있다. 이를 위하여 서울, 인천, 경기지 역에 소재한 334명을 대상으로 SPSS 18.0과 AMOS 18.0 프로그램을 활용하여 구 조방정식 모형분석을 실시하였으며, 다음과 같은 결론을 얻었다. 첫째, 스포츠 commitment 수준이 높아질수록 스포츠 flow 수준이 높아진다. 둘째, 스포츠 commitment 수준이 높아질수록 운동중독 수준이 높아진다. 셋째, 스포츠 flow는 운동중독에 유의미한 영향을 미치지 못한다. 이러한...

지금까지 청소년 혹은 청소년기를 대상으로 하는 이론이나 연구들에서의 공통된 주장은 아동기로부터 성인기로 넘어가기 위한 과도기로서 불안정성과 미성숙성 더 나아가 혼란성 등으로 특징지우고 있다. 이러한 주장은 청소년기를 크게 두 가지 측면에서 설명을 가능하게 한다. 하나는 청소년기가 안고 있는 그러한 특징들이 전반적인 생활 장면에서의 부적응을 초래하고 갈등이나 문제를 야기 시킬 수 있다고 하는 부정적 측면으로 설명하는 방식이다. 이 경우 청소년들은 사회가 추구하는 가치관이나 규범에 부합될 수 있게 하기 위한...

The purpose of this study is to develop a teaching and learning model for collaborative learning in mobile learning (m-learning) environments. For this purpose, this study utilized a literature review and a three-round Delphi method that employed three expert panels to develop the teaching and learning model. The teaching and learning model developed in this study includes six primary phases: (1) providing orientation of mobile-based collaborative learning, (2) guiding strategies for improving...

We demonstrated an effective way of preparing melt spinnable mesophase pitches via catalytic hydrogenation of petroleum residue (fluidized catalytic cracking-decant oil) and their subsequent thermal soaking. The mesophase pitches thus obtained were analyzed in terms of their viscosity, elemental composition, solubility, molecular weight, softening point and optical texture. We found that zeolite-induced catalytic hydrogenation under high hydrogen pressure contributed to a large variation in the...

In this study, magnetite (Fe3O4) nanoparticles were electrochemically synthesized in an aqueous electrolyte at a given potential of -1.3 V for 180 s. Scanning electron microscopy revealed that dendrite-like Fe3O4 nanoparticles with a mean size of < 80 nm were electrodeposited on a glassy carbon electrode (GCE). The Fe3O4/GCE was utilized for sensing chloramphenicol (CAP) by cyclic voltammetry and square wave voltammetry. A reduction peak of CAP at the Fe3O4/GCE was observed at 0.62 V, whereas...

In this study, Fe-Ni bimetallic catalyst supported on kaolin is prepared by a wet impregnation method. The effects of mass of kaolin support, pre-calcination time, pre-calcination temperature and stirring speed on catalyst yields are examined. Then, the optimal supported Fe-Ni catalyst is utilised to produce multi-walled carbon nanotubes (MWCNTs) using catalytic chemical vapour deposition (CCVD) method. The catalysts and MWCNTs prepared using the optimal conditions are characterized using high...

Taguchi’s experimental design was employed in the melt spinning of molten mesophase pitch to produce carbon fibers. The textures of the obtained carbon fibers were radial with varied crack angles, as observed by scanning electron microscopy and polarized optical imaging. The diameter, crack angle, preferred orientation, and tensile modulus of the produced samples were examined to investigate the influence of four spinning variables. The relative importance of the variables has been emphasized...
