The purpose of this study was to elucidate the relationship between the energy expenditure and the level of physical performance in preschool-age children. Seventy-six boys (5-6 years of age) had motor performance tests (25 m run, soft-ball throw, standing-long-jump, Zig-Zag run, upright handstand jog time, sit-and-reach, one-leg-balance) . Twenty boys were divided into two groups. One consisted of ten boys as the superior group and the other ten boys as the inferior group in results of the motor performance tests.
Energy expenditure was calculated from oxygen intake measured by each child's HR-VO₂ regression equation in a treadmill running test and 24-hour heart rate measurement by monitoring recorder. Daily energy uptake was estimated from the weight and kind of food recorded by their parents.
Energy expenditure in kindergarten, at home and in one day for the superior group were found to be higher than those for the inferior group. Energy uptake in the superior group showed a significant-ly higher value than that in the inferior group. It can be concluded that the children of the superior group appeared to be more active, since test and monitoring measurements showed they had more energy expenditure and energy uptake.

Placenta previa presents a highest risk to pregnancy, and placenta accreta is the most serious. Placenta accreta requires cesarean delivery and often results in massive obstetric hemorrhage and higher maternal morbidity. Challenges associated with cesarean delivery techniques may contribute to increased maternal blood loss and morbidity rates. Several recent obstetric studies reported the usefulness of transverse uterine fundal incision for managing placenta accreta. We present a case of placenta percreta that was treated by a transverse fundal incision. We successfully avoided cutting through the placenta and helped decrease maternal blood loss. After delivery, the patient underwent a cesarean hysterectomy. Postoperative day 48, she experienced watery discharge and was diagnosed with vaginal fistula. We present our case and review the literature.
