the maxillary sinus are essential for diagnosing sinus pathoses and planning a proper dental implant. The topography of the inferior wall with the maxillary root apices varies according to an individural's age, size and the degree of pneumatization of the maxillary sinus and the state of dental retention1). The first and second molar roots are most commonly in close proximity to the inferior wall of the maxillary sinus. Occasionally the projecting roots are usually separated from it by various... -

The edentulous posterior maxillary region presents unique and challenging conditions in implant dentistry compared with other regions of the jaws1,2). The available bone is lost from the inferior expansion of the sinus and residual ridge resorption after tooth loss. These factors increase stress to the implants. However, despite these concerns, treatment methods designed specifically for this area allow it to be as predictable as any other intraoral region. -

Three elementary school students with autism spectrum disorders (ASDs) and their peers in cooperative learning groups participated in lexical and goal inference making in a cooperative story mapping intervention. A multiple-baseline design across participants was implemented to assess the intervention effect on reading comprehension skills of students with ASDs. Generalization of learned skills and social validity of the participants were also examined. Students with ASDs as well as peers... -

As part of a cluster randomized controlled trial (Bundy et al., 2017), the after school-hours activities of 5-7 year old children were recorded by parents and other adult carers on four consecutive weekdays between 3:30pm-7:00pm. Records of time use showed most time was spent indoors in activities involving low levels of physical activity. The most-frequently-recorded activity was screen time, accounting for approximately one quarter of all activities. Higher levels of physical activity were... -

This article explores how children of Latino immigrants responded to a learning environment where they could influence how and what they learned. Using ethnographic data from the much larger Agency and Young Children project in the United States, this article describes how a particular six year old classroom serving mostly children of Latino immigrants responded in ways that not only increased content knowledge in subjects such as science and literacy but also increased the amount of shared or... -

Early Childhood services are becoming an increasingly significant part of children’s lives. As such they offer vital opportunities for children to engage in physically challenging active play in a safe and secure environment. However, in an increasingly ‘risk averse’ society an over-emphasis on safety has seen such play opportunities eroded. This qualitative study explored Early Childhood practitioners’ (n = 17) beliefs about risk-taking and their provision of ‘risky’ play opportunities in... -

본 연구의 목적은 아동 비만의 원인을 평가하고 적절한 해결책을 제안하는데 있다. 비만은 즉각적이고도 장기적인 결과를 가져오며 현재의 비만율 증가는 괄목할만한 주의를 요하고 있다. 과체중 어린이들은 고혈압, 높은 콜레스테롤, 2형 당뇨와 같은 심혈관계의 질병에 노출될 확률이 매우 높다. 더욱이 비만 아동은 비만인 어른이 될 확률이 높으며 어린 시절의 비만은 심리적이며 정서적인 문제를 동반한다. 또한 비만인 아동은 놀림과 왕따의 대상이 되며 낮은 자존감과 자아상을 가질 가능성이 매우 높다. 비만은 유전, 행동, 환경,... -
