Over-expression of epidermal growth factor receptor (EGFR) has been identified as a common feature associated with clinical outcome in many types of cancer, including squamous cell carcinoma of the oesophagus (SCCO). However, the clinical importance of EGFR over-expression in SCCO remains unsettled as conflicting results exist. Therefore we carried out the present meta-analysis of published studies for clarification. A total of 13 studies including 1, 150 patients were enrolled. EGFR over-expression was positive in 722 of these cases. With EGFR over-expression, patients had higher depth of invasion, vascular invasion, and poor prognosis. However, expression had no relation with degree of differentiation, histological grade, lymph node metastasis, clinical stage or lymphatic invasion. EGFR over-expression is probably a valuable predictor for the T stage, vascular invasion and OS, and it could be used as a poor prognosis indicator for the esophageal SCC patients. Targeting therapy to EFGR should be considered to the combined treatment in SCCO.

Background Polydactyly of the foot is one of the most frequent anomalies of the limbs. However, most classification systems are based solely on morphology and tend to be inaccurate and less relevant to surgical methods and results. The purpose of this study is to present our new classification of polydactyly of the foot, which can serve as a predictor of treatment and prognosis. Methods To find a correlation between the various morphologic traits of polydactyly of the foot and the treatment plan and outcomes, we reviewed 532 cases of polydactyly of the foot in 431 patients treated in our hospital, expanding on our previous study that described polydactyly based on the importance of metatarsal bone status and varus deformity. The records of patients were evaluated and compared with previous studies at other centers. Results Unsatisfactory results were seen in 36 cases, which included 5 cases of incomplete separation due to syndactylism, 23 cases of axis deviation, and 8 cases of remnants of extradigit metatarsal bones. The locus of the polydactyly, or the digit which was involved, did not seem to affect the final postoperative outcomes in our study. Three factors-syndactylism, axis deviation, and metatarsal extension-are the major factors related to treatment strategy and prognosis. Therefore, we developed a new classification system using three characters (S, A, M) followed by three groups (0, 1, 2), to describe the complexity of polydactyly of the foot, such as $S_1A_2M_2$. Conclusions Our new classification could provide a communicable description to help determine the surgical plan and predict outcomes.

The purpose of this study was to examine the stressors, coping styles, communication with mother, school adaptation and predictors for school adaptation. The subjects of this study consisted of 354 children. They were 6th grade of elementary school in Taegu city. The periods of study was from march 10, to march 18, 2000. Data were analyzed by SAS computer programme. The results of this study were as follows: 1. The mean score for stressor was 39.91 in children(range 24-72). The higher stressor among three subgroups of stressor was mass media stressor. The degree of stressor revealed to be influenced significantly economic status. 2. The most frequently used coping style was problem-oriented coping style(M=18.94) in children. The degree of emotion-oriented coping style revealed to be influenced significantly family's atmosphere 3. The mean score for communication with mother was 72,44 in children(range 20- 100). The degree of communication with mother revealed to be influenced significantly sex, economic status, family' atmosphere. 4. The mean score for school adaptation was 62.48 in children(range 25-100). The higher school adaptation among five subgroup was rule dimension. The degree of school adaptation revealed to be influenced significantly sex, birth, mother's job, economic status, family's atmosphere. 5. School adaptation were positively correlated with communication with mother, problem- oriented coping style(r=0.40 p<0.001) (r=0.30 p<0.001). 6. School adaptation were negatively correlated with emotion-oriented coping style, stressor (r=-0.16 p<0.01)(r=-0.13 p<0.01). 7. Forward multiple regression analysis revealed that the most powerful predictor was the variable communication with mother accounted for 15.25% in school adaptation. All variables accounted for 25.55% in school adaptation. From the above results, it can be concluded that teaching mother about importance of communication, encouraging to use problem-oriented coping style is necessary to improve school adaptation in 6th grade elementary school children

Objective : Preoperative parameters including the T1 slope (T1S) and C2-C7 sagittal vertical axis (SVA) have been recognized as predictors of kyphosis after laminoplasty, which is accompanied by posterior neck muscle damage. The importance of preoperative parameters has been under-estimated in anterior cervical discectomy and fusion (ACDF) because there is no posterior neck muscle damage. We aimed to determine whether postoperative subsidence and pseudarthrosis could be predicted according to specific parameters on preoperative plain radiographs. Methods : We retrospectively analyzed 41 consecutive patients (male : female, 22 : 19; mean age, $51.15{\pm}9.25years$) who underwent ACDF with a stand-alone polyether-ether-ketone (PEEK) cage (>1 year follow-up). Parameters including SVA, T1S, segmental angle and range of motion (ROM), C2-C7 cervical angle and ROM, and segmental inter-spinous distance were measured on preoperative plain radiographs. Risk factors of subsidence and pseudarthrosis were determined using multivariate logistic regression. Results : Fifty-five segments (27 single-segment and 14 two-segment fusions) were included. The subsidence and pseudarthrosis rates based on the number of segments were 36.4% and 29.1%, respectively. Demographic data and fusion level were unrelated to subsidence. A greater T1S was associated with a lower risk of subsidence (p=0.017, odds ratio=0.206). A cutoff value of T1S<$28^{\circ}$ significantly predicted subsidence (sensitivity : 70%, specificity : 68.6%). There were no preoperative predictors of pseudarthrosis except old age. Conclusion : A lower T1S (T1S<$28^{\circ}$) could be a risk factor of subsidence following ACDF. Surgeons need to be aware of this risk factor and should consider various supportive procedures to reduce the subsidence rates for such cases.

The ADHD, a common condition of childhood onset, is of critical educational and social concern at every level of school. Investigating the determinants of teachers' ADHD coaching and their relative importance is important for improving teaching and counseling practice in inclusive education setting. Based on three hundred and fifty three survey responses from elementary, junior and high school teachers, this research examines the impact of knowledge level, facilitating condition, cooperation with parents, attitude of teachers toward teachers' ADHD coaching. Statistical analysis shows that the knowledge level and facilitating condition influence the level of teachers' attitude, and that attitude has some impact on the cooperation level with parents, at 5% significance level. The cooperation with parent, one of two precedence factors of ADHD coaching, was identified to be significant, but attitude was shown to be nonsignificant predictor of ADHD coaching. A brief discussion concerning the critical needs of teachers is also presented.

This study was conducted to revalidate CQS and to examine the factors influencing cultural intelligence among Korean students studying abroad. 143 Korean students in USA and Canada were participated in the survey. Confirmatory factor analysis identified a model with four factors and CQS has negative correlation with acculturation stress and academic stress but positive correlation with subjective wellbeing. This findings suggest that CQS is a reliable and valid scale. Hierarchical regression analyses confirmed that personality is more significant predictor than cultural experiences for CQS. Discussion focuses on the importance of the findings, limitations and future directions.

The purpose of this study is to find out how work participation of the elderly and their general characteristics - socio-demographic, economic, and health traits - influence on their self-esteem. The data was collected through one on one interviews of 295 elderly. Data on general attributes and the discrepancies in the level of self-esteem between work participants and non-participants were analyzed by using t-test and ANOVA, while the effects of work participation on their self-esteem were analyzed by multiple regression analysis. Results of this study shows us that work participation is the strongest predictor that determine the level of self-esteem for the elderly. In other words, work participation can make the aged better off and give them a sense of security and satisfaction. Finally, these findings may be used for realizing us the importance of the work participation program and developing and designing new promising approaches of work participation program, which meet psychological needs of the elderly as well as their economic needs.
