Student contributions to research have been shown to effectively reflect on their communication and critical thinking skills. Short-term research courses offer opportunities for medical students to advance their research experience in subsequent high-demanding long-term research opportunities. The purpose of the present study was to describe the development, implementation, and evaluation of a ...
BACKGROUND Publication of scientific research papers is important for professionals working in academic medical centres. Quantitative measures of scientific output determine status and prestige, and serve to rank universities as well as individuals. The pressure to generate maximum scientific output is high, and quantitative aspects may tend to dominate over qualitative ones. How this pressure ...
INTRODUCTION The Lao People's Democratic Republic (PDR), like almost all countries, is faced with a shortage of qualified health workers in rural and remote areas. The situation has worsened due to the unbalanced distribution of the health workforce, resulting from a tendency to gravitate to more central areas. METHODS This cross-sectional study aimed to assess the proportion and associated f...
BACKGROUND A child's sleep pattern is important in defining his or her mental and physical well-being. Although we have reported previously on the utility of collecting 2 weeks of daily sleep logs, this type of record keeping is often onerous for the parents. Therefore, we established a new questionnaire, called the Japan Children's Study Sleep Questionnaire (JCSSQ), which is used to collect sl...
The Minabe-Tanabe Ume System in central Japan is defined as a Globally Important Agricultural Heritage (GIAHS) by the United Nations Food and Agriculture Organization. This study examined relationships between parcel-level plant diversity land use, management, development traditional sloped (Japanese apricot; Prunus mume) orchards adjoining level recently developed through large-scale cut-fill ...
A laboratory evaluation of bulk-fill versus traditional multi-increment-fill resin-based composites.
Some concerns exist, however, regarding bulk-fill composites. One proposed rationale for limiting composite increments to 2 mm is to allow the curing light to penetrate to the resin farthest away from the light source.1,2 A second reason for using 2-mm increments is to minimize the shrinkage and shrinkageinduced stress associated with composite polymerization. Contraction stresses that exceed t...
Sonication technology has recently been touted to decrease composite viscosity during delivery and may allow better cavity preparation adaptation and minimize voids. The purpose of this investigation was to evaluate the difference between conventional, hand-placed, incremental application of a standard hybrid resin-based composite (RBC) and sonicated application of a bulk-fill RBC in box-type a...
Introduction and aim: Bulk Fill composites have increased polymerization depth and their contraction stress, and cuspal deflection are reduced in comparison with conventional composites. Therefore, it is claimed that their microleakage is reduced. The aim of this study was to compare microleakage of (flowable and packable) Bulk Fill and conventional resin composites. Materials and Methods: Thi...
