The purpose of this study was to gain insight into how preschool-age children used gestures and body movement for understanding of science concepts during embodied play. Using a theoretical perspective on embodied cognition as considering gestures and body movements, we analyzed video data of embodied play science activity for 3-to-5-year-old children. Findings suggest that children’s gesture use and/or body movements varied in conjunction with verbal description. We also found that children often used their gestures and/or body movements independently as they developed and communicate their ideas. An important factor in how children use their gestures and body movements to shape and represent their ideas during embodied play of scientific concept, which they used their gestures following the teacher’s guidance and support to investigate science phenomenon. Our findings provide evidence for young children’s gestures and body movements for understanding science concepts as they showed through interactions with the teacher’s supports and guidance.

Purpose: To report the clinical outcomes of 360-degree keratolimbal allograft in 2 patients. Case summary: An 83-year-old female who had uncontrolled Mooren’s ulcer invading 360 degrees of the limbus with corneal opacity received a 360-degree keratolimbal allograft (KLAL). Another 63-year-old female who had central corneal opacity and corneal neovascularization due to severe limbal cell deficiency with chemical injury received a 360-degree KLAL. During the average 17.5 months of follow-up, both eyes were tectonically maintained without severe graft rejection. Conclusions: A 360-degree KLAL may be an effective tectonic procedure for corneal opacity caused by limbal stem cell deficiency. Herein, we report 2 cases of successfully performed 360-degree KLAL with a literature review. 목적: 360도에 걸쳐 시행한 동종각막윤부 이식술 2예의 임상경과를 보고하고자 한다. 증례요약: 9년 전부터 발생한 조절되지 않는 무렌각막궤양이 심해져 360도에 걸처 각막윤부를 침범하여, 각막의 얇아진 소견과 각막혼탁소견이 보이는 83세 여자환자와 화학화상 후에 발생한 심한 윤부결핍으로 각막신생혈관과 중심부 각막혼탁 소견이 보이는 63세여자환자에서 360도 동종각막윤부 이식술을 시행하였다. 평균 17.5개월의 경과관찰 동안 두 환자에서 심한 거부반응은 발생하지 않았고, 정상적인 각막상피가 재생되어 시력이 개선되었으며 안정적인 안구표면상태를 보여주었다. 결론: 360도 동종각막윤부 이식술은 윤부조직 손상으로 인한 난치성 안구표면 질환에서 효과적인 안구표면 재건술로 이용될 수 있다.

Pleurotus eryngii var. ferulae (PEF) is traditionally used in the prevention and treatment of lifestyle-related diseases. In this study, we investigated the ability of PEF extract to prevent obesity and metabolic diseases and explored the underlying mechanism. Mice were fed a high-fat diet (HFD) containing PEF extract for 12 weeks, and their body weight, adipose tissue and liver weights, and lipid profiles and blood glucose levels, were monitored. Fecal triglyceride (TG) levels were also measured and olive oil-loading tests were performed. Furthermore, the effect of PEF extract on pancreatic lipase (PL) activity was examined in vitro. Treatment with PEF extract for 12 weeks resulted in a significant decrease in the HFD-induced increases in body weight, white adipose tissue weight, liver weights, and lipid profiles, and improved glucose tolerance and insulin sensitivity. To assess the mechanism underlying the effect of PEF extract on obesity and diabetes, we investigated its role in inhibiting lipid absorption. Consumption of an HFD containing PEF extract significantly increased the TG level in feces compared with the controls, suggesting inhibition of TG absorption in the digestive tract. Furthermore, PEF extract suppressed the increase in serum TG levels resulting from oral administration of a lipid emulsion to mice, confirming inhibition of TG absorption. Moreover, PEF extract inhibited PL activity in vitro. Our combined results indicate that the anti-obesity and antidiabetic effect of PEF extract in mice fed an HFD may be caused by inhibition of lipid absorption as a result of reduced PL activity.
