Abstract	The present study investigates whether directing five- to six-year-old children's attention to hypothetical resource recipients that included familiar and non-familiar people would affect their favoritism toward a familiar person, as reflected in how they allocated resources. In Experiment 1, we instructed participants to give one of several stickers to another person or keep all the stickers for themselves. Under the control conditions, participants more frequently gave stickers to friends than to non-friends. However, when asked about others' emotions, they distributed stickers equally among friends and non-friends. Therefore, focusing on others' thoughts reduced participants' favoritism toward friends. Experiment 2 tested whether focusing on both emotional valences would affect favoritism toward a familiar person, as reflected in children's resource distribution choices. Experiment 2 was identical to Experiment 1, except we asked participants about the other person's emotional valence. When asked about others' negative emotions, participants distributed the stickers equally between themselves and others. However, when asked about others' positive emotions, they distributed more stickers to friends than to non-friends. Neither others' emotional valence nor group status affected the perceived intensity of their emotion or the participant's emotional state. These results suggest that children's favoritism toward friends can be reduced by encouraging them to think about others' negative emotional states.

Abstract	For improved examination of video capsule endoscopy (VCE) and device-assisted enteroscopy (DAE), bowel preparation is an essential issue. Multiple factors like air bubbles, food material in the small bowel, and gastric and small bowel transit time affect the small bowel visualization quality (SBVQ), diagnostic yield (DY) and cecal completion rate (CR). Bowel preparation with polyethylene glycol (PEG) solution enhances SBVQ and DY, but it has no effect on CR. Bowel preparation with PEG solution 2 L is similar to PEG 4 L in SBVQ, DY, and CR. Bowel preparation with fasting or PEG solution combined with anti-foaming agents like simethicone enhance SBVQ, but it has no effect on CR. Bowel preparation with prokinetics is not commonly recommended. Optimal timing for purgative bowel preparation has yet to be established. However, the studies regarding bowel preparation for DAE are not sufficient. European Society of Gastrointestinal Endoscopy (ESGE) recommends 8-12 hours fasting from solid food and 4-6 hours fasting from liquids prior to the antegrade DAE. For retrograde DAE, colonoscopy preparation regimen is recommended. This article reviews the literature and ESGE, 2013 Korean published guidelines regarding bowel preparation for VCE and DAE, following suggestion for optimal bowel preparation for VCE and balloon enteroscopy.

Abstract	The current research examined whether children's expectations about labeling conventions can be influenced by limited exposure to a foreign language. Three- to four-year-old Korean children were presented with two speakers who each assigned a novel label either in Korean or Spanish to a novel object. Children were asked whether both labels were acceptable for the object. Children who had more exposure to a foreign language through live social interaction, but not through media, were more likely to accept both Korean and Spanish labels. These findings indicate the influence of social interaction in foreign language exposure on children's understanding of different labeling conventions.

Abstract	Although it is well known that children of East Asian immigrants show higher academic achievement than native-born North American children, the social-cognitive determinants of this difference remain poorly understood. Given the importance of executive functions (EF) for academic achievement, and evidence that EF develops more quickly in East Asian compared to North American cultures, it is conceivable that differences in academic achievement might be rooted in EF differences between these groups. We examine this possibility by reviewing evidence of cross-cultural differences in EF development but find core concepts and findings limited in several key respects. To address these limitations, we propose a framework for relating EF, culture, and academic achievement that draws on new theoretical ideas about the nature of EF and its relation to social context. We conclude by discussing avenues for future research on the relations between culture, executive functions, and academic achievement.

Abstract	To learn new words, particularly verbs, child learners have been shown to benefit from the linguistic contexts in which the words appear. However, cross-linguistic differences affect how this process unfolds. One previous study found that children's abilities to learn a new verb differed across Korean and English as a function of the sentence in which the verb occurred (Arunachalam et al., 2013). The authors hypothesized that the properties of word order and argument drop, which vary systematically in these two languages, were driving the differences. In the current study, we pursued this finding to ask if the difference persists later in development, or if children acquiring different languages come to appear more similar as their linguistic knowledge and learning capacities increase. Preschool-aged monolingual English learners (N = 80) and monolingual Korean learners (N = 64) were presented with novel verbs in contexts that varied in word order and argument drop and accompanying visual stimuli. We assessed their learning by measuring accuracy in a forced-choice pointing task, and we measured eye gaze during the learning phase as an indicator of the processes by which they mapped the novel verbs to meaning. Unlike previous studies which identified differences between English and Korean learning 2-year-olds in a similar task, our results revealed similarities between the two language groups with these older preschoolers. We interpret our results as evidence that over the course of early childhood, children become adept at learning from a larger variety of contexts, such that differences between learners of different languages are attenuated.

Abstract	Vitamin D is considered to be the main mediator of the beneficial effects of sun exposure. In humans, highest expression of Vitamin D receptors is found in the intestinal tract. In addition, 1α,25-dihydroxyvitamin D3 (or calcitriol), the most active Vitamin D metabolite, plays important homeostatic roles in the intestine, particularly calcium absorption. Vitamin D deficiency is defined as a serum 25-hydroxyvitamin D [25(OH)D] level of < 20 ng/mL. Previous studies show that higher circulating 25(OH)D levels are associated with reduced risk of colorectal cancer (CRC) and improved survival. Most research to date has been conducted in animals, specifically mice. Although human studies have a limited number of participants, one study recruiting a large cohort of patients with advanced or metastatic CRC revealed that higher plasma 25(OH)D levels are associated with improved overall and progression-free survival. However, the effects of Vitamin D supplementation on incidence and mortality of CRC remain inconclusive. Although Vitamin D may help to prevent cancer, there is a paucity of research demonstrating conclusively that Vitamin D alters prognosis after chemotherapy. Here, we review the mechanisms by which Vitamin D affects CRC, as well as the results of clinical, epidemiological, and human intervention studies. We also discuss current perspectives and future directions regarding Vitamin D and CRC.

Abstract	The present research investigated whether six-month-olds who rarely produce pointing actions can detect the object-directedness and communicative function of others' pointing actions when linguistic information is provided. In Experiment 1, infants were randomly assigned to either a novel-word or emotional-vocalization condition. They were first familiarized with an event in which an actor uttered either a novel label (novel-word condition) or exclamatory expression (emotional-vocalization condition) and then pointed to one of two objects. Next, the positions of the objects were switched. During test trials, each infant watched the new-referent event where the actor pointed to the object to which the actor had not pointed before or the old-referent event where the actor pointed to the old object in its new location. Infants in the novel-word condition looked reliably longer at the new-referent event than at the old-referent event, suggesting that they encoded the object-directedness of the actor's point. In contrast, infants in the emotional-vocalization condition showed roughly equal looking times to the two events. To further examine infants' understanding of the communicative aspect of an actor's point using a different communicative context, Experiment 2 used an identical procedure to the novel-word condition in Experiment 1, except there was only one object present during the familiarization trials. When the familiarization trials did not include a contrasting object, we found that the communicative intention of the actor's point could be ambiguous. The infants showed roughly equal looking times during the two test events. The current research suggests that six-month-olds understand the object-directedness and communicative intention of others' pointing when presented with a label, but not when presented with an emotional non-speech vocalization.

Abstract	This study examined whether infants assume that people will help others to achieve specific goals. Seventeen-month-old infants watched familiarization events in which a competent agent succeeded in climbing hills while an incompetent agent failed to do so. In subsequent test events, the competent agent either helped the incompetent agent reach the top of the hill (helping event) or simply passed the incompetent agent and reached the top of the hill alone (ignoring event). The infants looked reliably longer at the ignoring event than at the helping event. These findings suggest that, by at least the age of 17 months, infants expect a competent agent to help an incompetent agent. Our findings provide evidence that infants in their second year of life possess some expectations of others' prosociality. Statement of contribution What is already known? Infants begin to reliably produce helping behaviours during their second year of life. Infants expect others to help an agent who is in need, not one who is not in need. Infants expect others to help, not ignore, another in need when linguistic information explicitly signals that the agent and the recipient belong to the same social group. What the present study adds? Infants expect someone to provide help rather than to ignore another in need under some circumstances with no linguistic information about their social group membership. Infants expect an agent to be a helper, not a bystander, even when they lack information about the agent's moral characteristics.
