Earth science is the study to explore the planet in which we live. Among these earth science geology of the area it can be the most critical and important study. However, because of the size and scope is too broad temporal spatial eurona covered in geology is true that many students find difficult about the geology field. In this study, in conjunction with landscape formation of geologic time for the concept to be among the core areas of Geology examined the concept and recognize it as the destination for high school students. Is a test tool for the analysis was adapted for use by Jolley (2010) has developed LIFT (The Landscape Identification and Formation Test). Currently we fix the strip to match the country through a validity check of the curriculum. Results of the study were as follows: First, the ability to check the landscape and formation is expected to estimate the time and the liberal arts students was higher than the natural science students. The reason for this seems to be the influence of learning geographical subjects. Second, the concept of geological time was found to lack both natural science and liberal arts students. The reason is that the students in the previous process because it deals with the concept of geologic time from the top of Earth Science Education II seems to be because there was no chance of learning about geological time. Third, the results confirm the confidence of the students surveyed in the landscape formation time natural science students was higher than liberal arts students. The research measured gender boys higher than girls. Fourth, the students on the landscape and geological time was found to have a number of misconceptions. This appears to be due to the students to feel difficulty in thinking of the concept because the need to understand the abstract geologic time. Therefore, it is necessary just to hold misconceptions about the concept of geology students have through the study of the landscape and geological time.

Undifferentiated (embryonal) sarcoma is a rare malignancy of the liver in children and young adults. Seven cases of undifferentiated (embryonal) sarcoma of the liver pathologically verified at Seoul National University Children's Hospital between 1986 and 1999 were retrospectively analyzed. There were three girls and four boys, and their mean age at diagnosis was 12.1 years (range 7-13 years). Six patients presented with an abdominal mass or pain, and one with weight loss. Tumor size ranged from $8.0{\times}8.0$ cm to $15.0{\times}15.0$ cm. Four tumors were located in the right lobe, two in the left lobe and one in both. One patient died during chemotherapy. Initial complete resection was accomplished in three patients. Two patients underwent complete resection after chemotherapy. Five patients with complete resection survived without evidence of disease for 8, 11, 13, 28, and 84 months. A patient with partial resection and chemotherapy died of sepsis during chemotherapy 19 months after complete surgical resection. Adjuvant chemotherapy and radiotherapy were performed in all patients after complete surgical resection. In conclusion, though undifferntiated (embryonal) sarcoma of the liver is highly malignant, the combination therapy of surgery, chemotherapy and radiotherapy appears to result in a favorable prognosis.

Objectives : A substantial number of craniopharyngiomas recur despite gross total excision. The purpose of our study was to investigate pattern of recurrence and to verify prognostic factors for recurrence after gross total excision of craniopharyngiomas in children. Methods : A series of 36 patients with craniopharyngiomas were reviewed. All patients had undergone gross total excision and none of them received radiotherapy after initial surgery. Fifteen were girls and twenty-one were boys, with a mean age of 7.3 years(range, one to 15 years). The mean follow-up period was 52 months(range, one to 149 months). Recurrence was noted in 14 patients within 83 months(mean 31.4 months). Results : The overall three-year recurrence free survival rate was 65%, and the five-year recurrence-free survival rate was 55%. Regular neuroimaging follow-up at six to 12-month intervals detected tumor recurrence of a smaller size before symptoms developed(p<0.05). At the first surgical procedure, the optic nerve/chiasm(n=23) was the most common adhesion site. The most frequent sites of recurrence were the optic nerve/chiasm(n=6) and the pitiutary fossa(n=6). Tumor location was the single significant clinical predictor of recurrence. The five-year recurrence-free survival rate was 39% for those who had an intrasellar tumor component and 81% for those who did not (p<0.05). Conclusion : Craniopharyngiomas with intrasellar components should be followed cautiously and regular followup of patients should be emphasized, even when the tumors are totally resected.

Purpose: We investigated the clinical features and factors affecting the choice of treatment modality and the course of pediatric gallstone (GS) disease. Methods: We retrospectively analyzed the medical records of 65 patients diagnosed with GS using imaging studies between January 2009 and December 2017 were included. Results: This study included 65 patients (33 boys and 32 girls; mean age, 8.5±5.3 years; range, 0.2-18 years) who primarily presented with abdominal pain (34%), jaundice (18%), and vomiting (8%). Idiopathic GS occurred in 36 patients (55.4%). The risk factors for GS included antibiotic use, obesity, hemolytic disease, and chemotherapy in 8 (12.3%), 7 (10.8%), 6 (9.2%), and 4 patients (6.2%), respectively. We observed multiple stones (including sandy stones) in 31 patients (47.7%), a single stone in 17 (26.2%), and several stones in 17 (26.2%). GS with a diameter of <5 mm occurred in 45 patients (69.2%). Comorbidities included hepatitis, choledocholithiasis, cholecystitis, and acute pancreatitis in 20 (30.8%), 11 (16.9%), 11 (16.9%), and 4 patients (6.2%), respectively. Ursodeoxycholic acid (UDCA) was administered to 54 patients (83.1%), leading to stone dissolution in 22 patients (33.8%) within 6 months. Cholecystectomy was performed in 18 patients (27.7%) (mean age, 11.9±5.1 years). Most patients treated surgically had multiple stones (83%) and stones measuring <5 mm in size (89%), and 66.7% of patients had cholesterol stones. Conclusion: Cholecystectomy is feasible in patients with small-sized or large numbers of GS and those with persistent abdominal pain and/or jaundice. UDCA administration with close follow-up is recommended in patients with uncomplicated GS.

Objective : Life-threatening hemispheric stroke is associated with a high mortality and morbidity. Decompressive hemicraniectomy has been regarded as an effective treatment option for refractory intracranial hypertension. Here, we reported the clinical course of 5 children with decompressive craniectomy and duroplasty after non-traumatic refractory intracranial hypertension. Methods : Four toddlers and one preschool-girl were included in this study; there were 3 boys and 2 girls with a mean age of 34.6 months (range 17-80). Decompressive craniectomy including duroplasty was performed in cases of dilatation of pupil size after intensified standard medical therapy had proven insufficient. All children had a Pediatric Glasgow Coma Scale score <8 at pre-operation state. The mean time-point of craniectomy after stroke attack was 12 hours (range 4-19). Results : During the long-term follow-up period (mean 47.6 months), no children died. One year later, when we checked their Glasgow Outcome Scale scores, only one toddler received a score of 4 (moderate disability). But the others had good recoveries although they had minor physical or mental deficits. According to the Pediatric Cerebral Performance Category Scale, 4 children received a score of 2 (mild disability). Conclusion : Despite our small cases, we suggest that decompressive hemicraniectomy and duroplasty is an acceptable and life-saving treatment for refractory intracranial hypertension after unilateral hemispheric stroke in toddlers and preschool children.

Background: Vitamin D receptor (VDR) gene has been a subject of extensive pharmacogenetic research recently. Association studies between different types of cancers including prostate cancer (PCa) and VDR gene polymorphism have also been conducted. The objective of this study was to find possible associations between PCa and VDR gene polymorphisms in the Pakistani population. Materials and Methods: A total of 162 subjects, including prostate cancer patients and controls, were genotyped for Apa I, Taq I and Fok I polymorphisms in the VDR gene using allele specific PCR, PCR-RFLP and direct DNA sequencing. Allelic frequencies were tested for Hardy-Weinberg equilibrium and associations between the genetic markers and PCa were calculated using logistic regression. Results: Apa I CC genotype was found to have strongest association with PCa risk, and "A" genotype was found to have protective effect. Fok I and Taq I did not have appreciable levels of association with PCa, although Taq I "TC" heterozygotes seemed to have some protective effect. Similarly the "C" allele of Fok I also seemed to have protective effect. Conclusions: To our knowledge, this is the first report showing association between VDR gene polymorphisms and PCa in Pakistan. Our findings may be somewhat skewed because of small sample size and tendency of consanguineous marriages in Pakistani society; nevertheless, it shows the trend of association and protective effects of certain VDR gene polymorphisms against PCa.
