Purpose: Preoperative planning has become essential in performance of total hip arthroplasty (THA). However, data regarding the effect of the planner's experience on the accuracy of digital preoperative planning is limited. The objective of this study was to assess the accuracy of digital templating in THA based on the surgeon's experience. Materials and Methods: A retrospective study was conducted. An analysis of 98 anteroposterior pelvic radiographs, which were individually templated by four surgeons (two hip surgeons and two orthopaedic residents) using TraumaCad^® digital planning, was performed. A comparison of preoperatively planned sizes with implanted sizes was performed to evaluate the accuracy of predicting component size. The results of preoperative planning performed by hip surgeons and orthopaedic residents were compared for testing of the planner's experience. Results: Femoral stem was precisely predicted in 32.4% of cases, acetabular component in 40.3%, and femoral offset in 76.7%. Prediction of cup size showed greater accuracy than femoral size among all observers. No differences in any variable were observed among the four groups (acetabular cup P=0.07, femoral stem P=0.82, femoral offset P=0.06). All measurements showed good reliability (intraclass correlation coefficient [ICC] acetabular cup: 0.76, ICC femoral stem: 0.79). Conclusion: The results of this study might suggest that even though a surgeon's experience supports improved precision during the planning stage, it should not be restricted only to surgeons with a high level of experience. We consider preoperative planning an essential part of the surgery, which should be included in training for orthopaedics residents.

This study investigated whether people experience a correspondence between color hue-tone and the main characters' emotions in the 2012 British musical drama film, Les $Mis\grave{e}rables$ through three practical experiments. Six screen images, which represent the characters' different emotions (Parrot's six primary types including love, joy, surprise, anger, sadness, and fear) were selected. For each screen image, participants were asked to judge the degree of the character's dominant emotions evoked from 17 varied screen images, which consisted of original chromatic and achromatized images as well as 15 color-filtered images (5 hues X 3 tones of the IRI color system). These tasks revealed that a chromatic color scheme is more effective to deliver the characters' positive emotions (i.e. love and joy) than an achromatic one. In addition, they proved that the hue and tone dimensions partially influence the relationships between the character emotions and colors.

By operation in aqueous environment at high temperature and pressure, the structural materials from Primary Heat Transport System (PHTS) cover with protective oxide films, which maintain the corrosion rate in admissible limits. A lot of potential factors exist, which conduct to degradation of the protective films and consequently to intensification of the corrosion processes. The existing experience of different nuclear reactors shows that the water chemistry has an important role in integrity maintaining of the protective oxide films. To investigate the influence of water chemistry (pH, O2 dissolved, $Cl^-$, $F^-$) on corrosion of some structural materials (carbon and martensitic steel, Zr and Ni alloys) and to establish the maximum permissible values, corrosion experiments by static autoclaving and electrochemical methods were performed. The experimental results allowed us to establish the contribution of the water chemistry in initiation and evolution of some accelerated corrosion processes.

The purpose of study was to test the hypothesis that preschool children who experienced nursing caries have high dft index and caries activity in primary dentition. One thousand and seventy-five preschool children from 4 to 6 years old were examined for their caries experience and salivary invertase activity by Resazurin Disc Test. Nursing caries group was identified by the criteria of having more decayed and filled teeth among the upper incisors than among the upper molars. The prevalence of nursing caries was 15.8%. The dft index of nursing caries group was significantly higher than that of the other groups except the rampant caries group(P<0.01). The Resazurin Disc Test score of nursing caries group was significantly higher than that of the other groups(P<0.01) and there was no difference between nursing caries group and rampant caries group. Therefore, it is recommended that children who experienced nursing caries should be incorporated in the caries prevention program through the primary and mixed dentition.

This report is an review of 5 cases of congenital esophageal atresia associated with tracheoesophageal fistula which were treated in the Department of Thoracic and Cardiovascular Surgery, Chonnam University Hospital from January, 1987 to February, 1989. First patient that was associated with VATER’s syndrome and moderate pneumonia, i.e., Waterston Category C was treated by gastrostomy, colostomy and primary anastomosis, but expired. Second patient that was weighed 2.2 Kg, suffered from moderate pneumonia was treated by gastrostomy, but died from asphyxia. The other patients were treated by primary repair. Any anastomotic leakage or gastroesophageal reflux was not found in these cases, but mild anastomotic strictures were found in these patients by postoperative esophagography. However, esophageal dilatation of anastomotic strictures was successful using the Griintzig balloon catheter.

심낭의 원발성 악성 중피종은심종양보다더 드문 질환으로 비록 와그너에 의해 1870년 처음 기술되었지만, 중피종이라는 용어는 아담에 의해 1910년 처음 사용되었다 대부분의 보고된 예들은 부검에 의해 진단 되었다. 생존시 진단은 세계적으로도 단지 40례 정도에 불과하다. 코헨에 의하면 부검한 예 중 500,000례에서 2.2례의 빈도를 보고하였다. 최근의 고찰된 분석을 보면 생존시 진단율은 전체 예 중 19-25%정도이다. 이 보고서는 심낭의 악성 중피종의 본 흉부외과학교실의 경험한 1예이다.

This study in an attempt to analyze the child's readiness for school and to pursue the facts that influence the readiness. the child's readinees for school was analyze on the developmental tasks in terms of physical, intellectual, social and moral development of first graders. On the facts that influence the readiness, age, sex, home environment and preschool experiences were surveyed. Ⅰ. Objectives 1. To survey the actual developmental conditions of physical, intellectual, social, and moral development of first graders. 2. To analyze the differences of school readiness in of sex, age and birth order. 3. To analyze the influence of home environment and preschool experience upon readiness. 4. To survey the differences of evaluation between parents and teachers on achievements of readiness. Ⅱ. Method 1. subjects were 848 mothers of primary school first graders and 20 primary school teachers. By the stratifeed sampling method, Seoul city was divided into three types of districts. 2. measurement tool was the check test for the child's readiness for school.

The primary function of intraoperative frozen consultation is to provide an as accurate and prompt diagnosis as possible during surgery and to guide the surgeon in further management. However, the evaluation of frozen section (FS) is sometimes difficult because of suboptimal tissue quality and frozen artifacts compared with routinely processed tissue section. The pathologist responsible for the FS diagnosis requires experience and good judgment. Ovarian tumors are a heterogeneous group of tumors including primary surface epithelial tumors, germ cell tumors and sex cord-stromal tumors, secondary tumors, and other groups of tumors of uncertain histogenesis or nonspecific stroma. Intraoperative FS is a very important and reliable tool that guides the surgical management of ovarian tumors. In this review, the diagnostic key points for the pathologist and the implication of the FS diagnosis on the operator's decisions are discussed.

The present study aimed to investigate the extent to which ordinary classrooms teachers are informed are familiar with Attention Deficit Hyperactivity Disorder 'ADHD'. The researcher adopted the descriptive approach. The sample of the study consisted of (89) male and female teachers who teach students from grade (1) to grade (6) at public primary schools in Northern Mazar Directorate of Education in Jordan. A questionnaire was employed as the primary tool for collecting the data. The findings of the current study indicated an average level of knowledge of ordinary classroom teachers about ADHD. The findings also indicated that there were no statistically significant differences in the extent of ordinary classroom teachers' knowledge of ADHD due to the variables (gender, qualification, professional experience, grade level being taught).
