Mauriac syndrome consists of a triad of poorly controlled diabetes, profound growth retardation and hepatomegaly. We experienced a case of Mauriac syndrome in an 18-year-old girl who had poorly controlled diabetes mellitus, short stature, hepatomegaly and central obesity. Also at the time of examination, she had complications of diabetic cataract and nephropathy. Fourteen years prior to admission, she was diagnosed as diabetes mellitus at a hospital. Thereafter, she had been managed with irregular insulin injection. On physical examination at admission, her height was 135cm(<3 percentile) and her weight was 39kg(<3 percetile). She was short and obese. The liver was 5 cm palpable below the right subcostal margin. Her sexual maturation was Tanner stage I. On ophthalmologic examination, the cataracts were observed on both eyes and diabetic retinopathy was absent. Diabetic nephropathy could not be confirrned by kidney biopsy due to her mother's refusal. We studied the hormonal, radiographic and histological abnormalities. The hormonal study was normal and the bone age was by delayed as much as 10 years. The liver biopsy revealed glycogen accumulation in hepatocyte. She was consistent with Mauriac syndrome. She was managed by strict diabetic control with insulin therapy, diabetic diet and intensive education. She was discharged with well controlled blood glucose. Five months later, growth acceleration and sexual maturation have not been observed, but hepatomegaly subsided. (J Korean Pediatr Soc 2000;43-837-841)

The congenital mesoblastic nephroma is the most common renal neoplasm seen in the first few months of life. This tumor usually benign, but local recurrences and metastases have been reported, and treatment is total nephrectomy. This entity must be differentiated from Wilm's tumor so as to avoid unnecessary postoperative irradiation and chemotherapy. Recently, we experienced a case of congenital mesoblastic nephroma in female newborn infant. Diagnosis was made with physical examination, plain roentgenogram of the abdomen, ultrasonography of the abdomen and I.V.P. and confirmed with microscopic examination. A brief review of the related literature was made on this subject.

Purpose:
It is essential to ensure the readiness for practice among undergraduate nursing students since the purpose of such education is to cultivate competent nurses who deliver high-quality and safe nursing. Astin's theory of student involvement suggests that this is affected by their personal factors and learning environment.
Methods:
We conducted a cross-sectional study between November 16, 2020 and December 21, 2020 which examined personal factors and aspects of the clinical learning environment among senior nursing students (n = 838) enrolled across 54 nursing schools in Korea. The participants were asked to fill out a self-administered online survey, which assessed demographic characteristics, self-esteem, depression, work-life balance, clinical learning environment, anxiety during clinical practicum, and readiness for practice. Readiness for practice was measured using the Casey-Fink Readiness for practice survey. We used structural equational modeling to test our hypothetical model.
Results:
The nursing students' readiness for practice was significantly affected by their self-esteem, work-life balance satisfaction, and clinical learning environment. Anxiety during clinical practicum directly influenced their readiness for practice.
Conclusion
Increasing self-esteem and work-life balance satisfaction, and improving their clinical learning environment by providing sufficient educational and clinical support, could help facilitate the transition from nursing schools to real-world practice for nursing students.

OBJECTIVES: Accurate assessment of energy expenditure is important for estimation of energy requirements in athletic children. The objective of this study was to evaluate the accuracy of accelerometer for prediction of selected activities' energy expenditure and intensity in athletic elementary school children. METHODS: The present study involved 31 soccer players (16 males and 15 females) from an elementary school (9-12 years). During the measurements, children performed eight selected activities while simultaneously wearing the accelerometer and carrying the portable indirect calorimeter. Five equations (Freedson/Trost, Treuth, Pate, Puyau, Mattocks) were assessed for the prediction of energy expenditure from accelerometer counts, while Evenson equation was added for prediction of activity intensity, making msix equations in total. The accuracy of accelerometer for energy prediction was assessed by comparing measured and predicted values, using the paired t-test. The intensity classification accuracy was evaluated with kappa statistics and ROC-Curve. RESULTS: For activities of lying down, television viewing and reading, Freedson/Trost, Treuth were accurate in predicting energy expenditure. Regarding Pate, it was accurate for vacuuming and slow treadmill walking energy prediction. Mattocks was accurate in treadmill running activities. Concerning activity intensity classification accuracy, Pate (kappa=0.72) had the best performance across the four intensities (sedentary, light, moderate, vigorous). In case of the sedentary activities, all equations had a good prediction accuracy, while with light activities and Vigorous activities, Pate had an excellent accuracy (ROC-AUC=0.91, 0.94). For Moderate activities, all equations showed a poor performance. CONCLUSIONS: In conclusion, none of the assessed equations was accurate in predicting energy expenditure across all assessed activities in athletic children. For activity intensity classification, Pate had the best prediction accuracy.

OBJECTIVES: The purpose of this study was to compare the physical activity level (PAL), the physical activity pattern and the energy expenditure in male and female elementary school soccer players using the accelerometer and the physical activity diary. METHODS: Twenty-five (male 11, female 14) elementary school soccer players (9–12 years) participated in this study. During their daily activities, they wore an accelerometer for seven days (five weekdays and two weekend days) and completed the physical activity diary for three days (two weekdays and one weekend day). PAL was calculated by using the physical activity diary and three equations (Pate Preschool, Freedson Children, and Freedson) were used to calculate the intensity of physical activity and energy expenditure from the counts of accelerometer. RESULTS: The average of physical activity by day of the week, CPM (Counts Per Minute) and METs (Metabolic Equivalents) were significantly higher in males (723.3 ± 149.2 CPM, 2.07 ± 0.18 METs) compared to females (505.6 ± 119.9 CPM, 1.79 ± 0.20 METs), but there was no significant difference in PAEE (Physical Activity Energy Expenditure) between the two groups (males: 15.5 ± 9.1 kcal/day, females: 11.5 ± 6.0 kcal/day). During weekdays, physical activity intensity was significantly higher in males compared to females at lunch time and training time than at other times. In both genders, the PAL was higher during weekdays (males 1.98, females 1.89) compared to weekend (males 1.62, females 1.61) (p<0.05). CONCLUSIONS: Our study observations suggest the necessity to develop an accelerometer equation for accurately evaluating the physical activity of elementary school athletes.

Primary leiomyosarcoma of the lung is very uncommon, and fewer than 50 cases now have been reported. Primary leiomyosarcoma of the lung resembles bronchogenic carcinoma in its clinical presentation and radiologic appearance. However, the former has some differences; younger onset than bronchogenic carcinoma, polypoid endobronchial growth, few positive cytologic examination of sputum and unusual lymph node metastasis. We experienced a case of primary leiomyosarcoma of the lung.
