사회과학분야 : 중학생의 학교 무용수업 참여경험이 자신감과 사회성 및 자아실현 형성에 미치는 영향

본 연구는 중학생의 학교 무용수업 참여경험이 자신감과 사회성 및 자아실현 형성에 미치는 영향을 규명하여, 청소년기 학생들의 학교 무용교육의 중요성을 재인식시키고 무용교육의 활성화를 위한 방안을 제시하는데 목적이 있다. 이에 충북지역의 2개 학교를 선정하여 주 1회, 1차시씩 무용수업에 참여한 학생들을 대상으로 설문지를 사용하여 총 311부를 최종 분석하였다. 연구문제 해결을 위해 SPSS 18.0 프로그램을 이용하여 t-test, ANOVA, 상관분석, 중다회귀분석을 실시하였으며, 그 결과 다음과 같은 결론이 도출되었다. 첫째, 개인적 특성에 따라 자신감, 사회성 및 자아실현에 차이가 있었다. 둘째, 학교 무용수업 경험특성에 따라 자신감, 사회성 및 자아실현에 차이가 있었다. 셋째, 학교 무용수업에서 자신감은 사회성에 유의한 영향을 미치는 것으로 나타났다. 넷째, 학교 무용수업에서 자신감은 자아실현에 유의한 영향을 미치는 것으로 나타났다. 이상의 연구 결과를 토대로 중학생의 학교 무용수업이 자신감과 사회성 및 자아실현에 다각적인 영향을 미치는 것을 알 수 있었다. The purpose of this study was to examine the influence of school dance instruction on the self-confidence, sociability and self-realization of middle school students in an effort to raise awareness of the importance of school dance education for adolescent students and seek ways of revitalizing dance education. The subjects in this study were the students who took a dance class on a weekly basis at two selected schools in North Chungcheong Province. After a survey was conducted, the answer sheets from 311 respondents were analyzed. To address the research questions of the study, the statistical package SPSS 18.0 was employed, and t-test, ANOVA, correlation analysis and multiple regression analysis were carried out. The findings of the study were as follows: First, there were differences among the students in self- confidence, sociability and self-realization according to their personal characteristics. Second, there were differences in self-confidence, sociability and self-realization according to the characteristics of their experiences of taking dance classes. Third, self-confidence exerted a significant influence on sociability in school dance instruction. Fourth, self-confidence had a significant impact on self-realization in school dance instruction.
PTEN Mutation Identified in Patient Diagnosed with Simultaneous Multiple Cancers

PTEN hamartoma tumor syndrome is a spectrum of disorders characterized by unique phenotypic features including multiple hamartomas caused by mutations of the tumor suppressor gene PTEN. Cowden syndrome and Bannayan–Riley–Ruvalcaba syndrome are representative diseases, and both have several common clinical features and differences. Because PTEN mutations are associated with an increased risk of malignancy including breast, thyroid, endometrial, and renal cancers, cancer surveillance is an important element of disease management. We report a germline mutation of the PTEN (c.723dupT, exon 7) identified in a young woman with a simultaneous occurrence of breast cancer, dermatofibrosarcoma protuberans, and follicular neoplasm. This case suggests that it is critical for clinicians to recognize the phenotypic features associated with these syndromes to accurately diagnose them and provide preventive care.

Pseudocirrhosis refers to a condition that shows changes in hepatic contour thatmimic cirrhosis radiographically in the absence of the typical histopathologicalfindings of cirrhosis. This condition has been observed in patients with cancermetastatic to the liver, both in those who have undergone prior systemic chemotherapyand those who have not. Pseudocirrhosis may cause difficulty in interpretationof the response to chemotherapy and hepatic decompression and complication ofportal hypertension have a negative effect on the prognosis. We report on a case ofbreast cancer with liver metastases that showed cirrhotic changes during diseaseprogression. Progression of liver metastases was confirmed by F18 fluorodeoxyglucosepositron emission tomography/computed tomography (PET-CT). We alsoperformed ultrasound-guided liver biopsy and confirmed tumor infiltration with severedesmoplastic fibrosis. This case suggests the pathogenesis of pseudocirrhosisthrough histopathological findings and the role of PET-CT in evaluation of the responseto chemotherapy in patients with pseudocirrhosis.

Graphene is a fascinating material for fabricating flexible and transparent devices owing to its thickness and mechanical properties. To utilize graphene as a core material for devices, the transfer process of graphene is an inevitable step. The transfer process can be classified into wet and dry methods depending on the surrounding environment. The adhesion between graphene and a target substrate determines the success or failure of the transfer process. As the surface energy of graphene is an important parameter that provides adhesion, it is useful to estimate the surface energy to understand the mechanisms of the transfer process. However, the exact surface energy of graphene is still disputed because the wetting transparency of graphene depends on the polarity of the liquid and target substrate. Previously reported results use graphene transferred by the wet method. However, there are few reports on the surface energy of graphene transferred by the dry method. In this study, the surface energy of graphene transferred by the wet and dry methods is estimated. Wetting transparency occurs for certain combinations of liquids and substrates. For graphene on a polar substrate, the surface energy decreases by 25 and 35% for the wet and dry transfer methods, respectively. However, the surface energy of graphene on dispersive substrates decreases by ~10% regardless of the transfer method. In conclusion, the surface energy of graphene is 36~38 mJ/m2, and differs depending on the transfer method and polarity of the substrate.
