Leiomyoma is a common benign tumor from smooth muscle cells, mostly in the uterus. Peritoneal leiomyomas (PLs) are extremely rare and mostly reported as disseminated peritoneal leiomyomatosis. However, to the best of out knowledge, radiologic findings of isolated PL are not reported in English literature. Herein, we introduce the radiologic findings of PL mimicking hepatic mass in a 34-year-old female. CT showed a mass with curvilinear heterogeneous enhancement at the liver's peripheral area. On MRI, the mass showed gradual and heterogeneous enhancement on gadoxetic acid-enhanced MRI and diffusion restriction. The radiologic diagnosis was a benign hepatic tumor, such as degenerated hemangioma, adenoma, and inflammatory myofibroblastic tumor; however, the mass was diagnosed as PL pathologically.

The purpose of this study was to examine the characteristics of observation and measurement inquiry process in the Korean science textbooks. For the inquiry process of observation, the higher grade textbooks contained more 'comparative observation' rather than 'simple observation'. Students should express their observation results in written words rather than verbal descriptions in the higher grade. For the inquiry process of measurement, the temperature measurement was the most frequent measurement activity. 'Measurement design' was found more frequently in the lower grade textbooks. The uses of measurement tools were not presented systematically and were presented restrictively when the relevant experiment wanted to use these tools. The higher grade textbooks include 'quantitative measurements' rather than 'qualitative measurements' and 'operation measurement' rather than 'simple measurement'. In the application of measurement results, we had difficulty in finding the activities related with the usage of unit, unit conversion, significant figure, error and uncertainty.

This study aimed to investigate the current situation of toothbrushing guidance with child care teachers in day care facilities caring and managing infants and young children and to grasp problems neglected in using toothpaste and guiding toothbrushing to provide basic data for measures to cope with them. This study included 165 child care teachers or teachers of the kindergartens who agreed with its purpose. By excluding 10 questionnaires with omitted or conflicting answers, 156 ones were finally analyzed in this study. The correlation between education about oral health and toothbrushing guidance, the subjects with and without the experience of the education did not show any significant difference in time to encourage toothbrushing, behaviors of toothbrushing guidance, guidance on prevention of toothpaste intake and perception of an appropriate amount of toothpaste (p>0.05) while perception of the importance of oral health was significantly related with the education on oral health (p<0.05). Therefore, education system for specialists in oral health to offer a specific and systemic education and oral health education programs for child care teacher, are considered to be necessary.

In this study, we built a thermal model for SNIPE 6U nano-satellite which has scientific mission for measuring science data in near Earth space environment and described thermal design based on the thermal model. And the validity of the thermal design was verified through the on-orbit thermal analysis. The thermal design was carried out mainly on the passive thermal control techniques such as surface finishes, insulators, and thermal conductors in consideration of the characteristics of the nano-satellite. However, the components with narrow operating temperature range and directly exposed to the orbital thermal environments, such as a battery and thrusters, are accomodated with heaters to satisfy the temperature requirements. On-orbit thermal analysis conditions are based on the basic orbital conditions of the satellite, and thermal analysis was performed for Normal mode, Launch & Early Orbit Phase (LEOP), Safehold mode, and Maneuver mode which are classified by the power consumption and the attitude of the satellite according to the mission scenario. The analysis results for each mode confirmed that every component satisfies the temperature requirement. In addition, the heater capacity and duty cycle of the battery and thruster were calculated through the analysis results of the Safehold mode.

The purpose of this study is to compare the amount of dentifrice used in general by the subjects with the amount of dentifrice both by Pea-size and by sideways application(transverse technique) after the subjects of dental hygiene students applied dentifrice on the toothbrushes for kids. The amount of dentifrice was calculated by the weight differences between toothbrush itself and toothbrush with dentifrice on it after toothbrushes for children were allotted to subjects. For the first measurement, the subjects were told to apply out the amount of dentifrice considered proper for children when they brush their teeth. For the second one, they were told to apply out the amount of Pea-size dentifrice recommended to children. Finally, the subjects had to applied dentifrice out on their toothbrush in the sideways or transverse technique after they were taught the way to applied dentifrice out. In this experiment, the average amount of dentifrice per usage when he or she brush his or her teeth as usual was 0.40 g, and the average amount of dentifrice applied to Pea-size application was 0.43 g, and the average amount of dentifrice applied to Transverse technique application was 0.26 g. Transverse technique not only can be easy to show and teach the way to both children and their parents, but also can be recommendable to children because it can minimize fluoride intake carelessly.

Introduction: This study intended to identify the current oral health care status and demand of care workers for oral health education. Methods: A survey was distributed to care workers working in 11 nursing homes for older people located in the Chungcheongdo Province. Of those distributed, 217 questionnaires were collected and analyzed. To analyze the collected data, a frequency analysis, t-test, and one-way analysis of variance(ANOVA) were performed using SPSS version 18.0. Results: The demand for an educational course on the 'Management of Oral Health Care for the Aged People' had a score of 4.22 points(full marks were 5.0 points), whereas the score for the necessity for control of oral health was 4.29 points. The control of oral health for the aged people suffering dysphagia scored 4.27 points, whereas the control of oral health for older people who have dementia was 4.27 points. The score for a course on the nutritional control for aged people having difficulties in masticating foods was 4.27. Conclusion: It is clear that the development of educational courses and standardized manuals for care workers on aspects of oral health care is necessary. Therefore, it would be desirable to develop institutional infrastructure for dental hygienists to educate care workers on oral health.

The purpose of the study is to develop an effective model of a science teachers' professional development program. This study consists of two parts: (1) the theoretical review of science teachers' professional development and (2) a case study of a science teachers' professional development programme in the UK. After reviewing recent research on pedagogical content knowledge and new approaches to educational research, the following suggestions emerged: (1) Continuing Professional Development(CPD) should be embedded in teachers' real practice in the classroom and (2) embedded in the everyday life of learners' within the community. (3) CPD should support the development of teachers' communities of professional practice. The case study of 'CPD through Portfolios of Evidence' in the British programme indicated that collecting explicit evidence of good practice in the classroom and establishing agreement as to what constitutes good practice in a teachers' community helped teachers' professional development. Finally, what emerged from the case study of the CPD programme in the UK and the theoretical review of PCK was the following. An effective CPD model of science teachers should comprise these three stages: (1) providing opportunities of professional development, (2) changing practice in the classroom and research, and (3) spreading and sustaining change. The whole process is circular.

Understanding the students' ability and tendency of self assessment is one of the important factors in helping their learning and in giving the appropriate feedbacks. The purposes of this study is to analyse the coincidency of the students' self-assessment with the teacher assessment, and the tendency of over and under estimation. The students performed open investigations and assessed their process skills by checking their investigation reports with a given checklist. The total mean of the 'Self-Assessment Capability(SAC)' was 0.73 by 1. The SAC was related to the achievement, not to the gender. The correlation between SAC and achievement was significantly positive(r=0.7, p<.01), and for the girls, the tendency was remarkable. Among the five areas of process skills of open investigation, students got the highest SAC score in the managing and interpreting data area, and the lowest SAC in the drawing conclusion area. The mean of 'Self-Assessment Tendency(SAT)' for all items showed that students overestimated their process skills. While the high achievement students underestimated their process skills, the middle and low showed the tendency of overestimation.
