Many studies have shown that high-altitude exposure could significantly influence human cognition, and the approaches which could enhance the human cognition in high-altitude hypoxia environment attract great attention. In the present study, we recruited a total of 60 subjects who had been migrated to Tibet University as adults for more than one year. These participants were randomly divided into the experimental group and the control group. The participants in the experimental group were instructed to complete a hyperbaric oxygen treatment, and those in the control group just completed a wait condition. By using the attention network test (ANT), the changes of the attention function before and after a single session of hyperbaric oxygen treatment were explored. The results showed that single hyperbaric oxygen treatment significantly improved the orienting function of attention, with an obvious post-intervention effect, but not the alerting and conflict function of attention. We also found a strong association between alerting function and conflict function after the end of intervention, suggesting the change of the overall performance of attention function. The present findings might suggest that the improvement of attention function by a single session of hyperbaric oxygen intervention is derived from the increase of general cognitive resources, rather than the transfer of cognitive resources within the attention system.

BACKGROUNDSelective attention is considered one of the main components of cognitive functioning. A number of studies have demonstrated gender differences in cognition. This study aimed to investigate the gender differences in selective attention in healthy subjects.

METHODSThe present experiment examined the gender differences associated with the efficiency of three attentional networks: alerting, orienting, and executive control attention in 73 healthy subjects (38 males). All participants performed a modified version of the Attention Network Test (ANT).

RESULTSFemales had higher orienting scores than males (t = 2.172, P < 0.05). Specifically, females were faster at covert orienting of attention to a spatially cued location. There were no gender differences between males and females in alerting (t = 0.813, P > 0.05) and executive control (t = 0.945, P > 0.05) attention networks.

CONCLUSIONSThere was a significant gender difference between males and females associated with the orienting network. Enhanced orienting attention in females may function to motivate females to direct their attention to a spatially cued location.

The purposes of this study were to measure the service mind and customer orientation of employees and to identify the effect of service mind on customer orientation in elementary school foodservices. The questionnaires were distributed to foodservice employees of the 19 elementary schools, but collected from 12 schools in Gwangju, Gyeonggi. The statistical data analysis was completed using SPSS (ver. 18.0) for the independent sample t-test, ANOVA, Cronbach's alpha, principal component analysis, hierarchical & K-means cluster analysis, Pearson' correlation analysis, and multiple regression analysis. Foodservice employees highly rated their service mind (3.94 out of 5 points), especially their perceptions on the importance of service (4.13 points). The effort to provide service was significantly different depending on the serving place (P<0.05). Employees had a high level of customer orientation (4.02 points), which was significantly influenced by age, position, or career (P<0.05), and cook license (P<0.01). As a result of cluster analysis for service mind, employees were divided into two groups: a low-service mind group (cluster 1) and a high-service mind group (cluster 2). Cluster 2 had a significantly higher overall customer orientation than cluster 1 (P<0.001). The pride in providing services (beta=0.390, P<0.01) and the perception of the importance of services (beta=0.297, P<0.05) showed a significant and positive effect on customer orientation.

PURPOSE: The purpose of this study was to identify the relationship among followership, organizational commitment, job satisfaction, turnover intention, and customer orientation in hospital nurses. METHODS: The participants in this study were 210 staff nurses in one university hospital. Data were analyzed using frequency, ANOVA, Pearson correlation analysis, and stepwise multiple regression. RESULTS: Followership had positive correlations with organizational commitment (r=.46, p<.001), job satisfaction (r=.41, p<.001), customer orientation (r=.47, p<.001). Followership had negative correlation with turnover intention (r=-.23, p<.001). The factor of followership influencing organizational commitment was active engagement, and this factor accounted for 23.3% of explanatory power. The factor of followership influencing job satisfaction was active engagement (F=45.00, p<.001), and this factor accounted for 17.8% of explanatory power. The factor of followership influencing turnover intention was active engagement (F=19.69, p<.001), and this factor accounted for 17.0% of explanatory power. The factors of followership influencing customer orientation were active engagement (F=51.38, p=.004) and independent, critical thinking (F=24.55, p=.011), and these factors accounted for 22.1% of explanatory power. CONCLUSION: Findings indicate a need to develop followership to promote organizational commitment, job satisfaction, and customer orientation and to decrease turnover intention in nurses.

PURPOSE: The purpose of this study was to identify the mediating effect of professionalism in the relationship between clinical competence and field adaptation in newly graduated nurses. METHODS: The participants in this study were 213 nurses from four tertiary hospitals who had less than 12 months of nursing experience. Data were collected during January and February, 2013. A structured questionnaire was used for data collection and data were analyzed using descriptive statistics, Pearson correlation coefficients, and path analysis with the SPSS/WIN 21.0 and AMOS 21.0 programs. RESULTS: The mean score for clinical competence was 2.85+/-0.25, for professionalism, 3.10+/-0.30, and for field adaptation, 2.79+/-0.37. There was a significant positive relationship between clinical competence and field adaptation. Also, professionalism was positively correlated with field adaptation. Professionalism showed mediating effects between clinical competence and field adaptation. Improvement of clinical competence increased professionalism and the increased professionalism raised the field adaptation. CONCLUSION: Based on these findings, orientation programs including strategies to increase professionalism, should be established to promote effective field adaptation in newly graduated nurses. These orientation programs can strengthen professionalism, the mediator between clinical competence and field adaptation in newly graduated nurses.

The supinator muscle originates from the annular ligament of the radius, and the muscle fibers and ligament take a similar winding course. Likewise, the coccygeus muscle and the sacrospinous ligament are attached together, and show a similar fiber orientation. During dissection of adult cadavers for our educational curriculum, we had the impression that these ligaments grow in combination with degeneration of parts of the muscles. In histological sections of 25 human fetuses at 10-32 weeks of gestation, we found that the proximal parts of the supinator muscle were embedded in collagenous tissue when the developing annular ligament of the radius joined the thick intermuscular connecting band extending between the extensor carpi radialis and anconeus muscles at 18-22 weeks of gestation, and the anterior parts of the coccygeus muscle were surrounded by collagenous tissue when the intramuscular tendon became the sacrospinous ligament at 28-32 weeks. Parts of these two muscles each seemed to provide a mold for the ligament, and finally became involved with it. This may be the first report to indicate that a growing ligament has potential to injure parts of the "mother muscle," and that this process may be involved in the initial development of the ligament.

PURPOSE: There have been studies on the patient-centeredness of medical students and physicians in South Korea, but no result has presented the patient-centered attitude of patients and doctors. So, this study intended to compare the attitudes of patients and doctors toward the roles that patients and physicians should play in the health care process. METHODS: One hundred and fifteen doctors and 264 patients participated in this survey using a structured questionnaire, including sociodemographic data and Patient Practitioner Orientation Scale (PPOS). The PPOS comprises sharing (sharing information, take part in decision making) and caring (respecting one's feelings, interpersonal relationships) subscales. RESULTS: The PPOS scores of the doctors and patient were 3.02 and 3.20. In detail, the doctors' sharing and caring scores were and 3.02 and 3.48, and the those of patients were 3.14 and 3.12, respectively. This results are enough to demonstrate that patients are likely to be patient-centered with regard to sharing and that doctors tend to be patient-centered in terms of caring. CONCLUSION: The patients' desire to obtain medical information and take part in decision making (sharing) are greater than those of doctors. Doctors had more patient-centered attitude than patients in terms of respects for one's feelings and interpersonal relationships (caring).

The establishment of clinical epidemiology has meant the improvement of the quality and quantity of clinical science because clinical epidemiology has contributed to the process of decision making across the full scope of clinical practice, including diagnosis, treatment, and care, as well as prevention. Epidemiological and statistical methodologies have been used to analyze scientific evidence on clinical problems. The orientation of evidence-based medicine introduced in the mid-1990s is the application of clinical epidemiology to clinical practice for individual patients. The concept of evidence-based medical practice has triggered the expansion of the scope and range of methods of clinical epidemiology. In spite of the global situation, the formal activity in the area of clinical epidemiology in Korean Medical Academic Association is negligible, with few clinical epidemiologists involved. One of several approaches to stimulating the practice of clinical epidemiology in Korea would be to foster clinical epidemiology as a specialization of clinical preventive medicine, which is one of the sub-specialties of preventive medicine in Korea.

PURPOSE: The aim of this study was to identify the effects of change commitment and learning orientation on the innovativeness of clinical nurse. METHODS: The participants in this study were 268 nurses, working in hospitals in Seoul, Gyeonggi and Gangwon Provinces, and Daejeon City. Data were collected from June to August, 2012. A structured questionnaire was used for data collect and data was analyzed using the SPSS/WIN program. RESULTS: The most significant predictors of innovativeness were education, normative commitment, continuance commitment and learning commitment. Continuance commitment negatively correlated with innovativeness. CONCLUSION: These findings suggest that nurses' commitment to change and learning commitment were strongly linked to innovativeness. Management-level workers in these hospitals should have the skills and strategies to promote commitment to change include developing positive expectations about change positive outcomes.

PURPOSE: The purpose of this study was to determine accurately the part of the tragus to be used to form the Ala-Tragal line or Camper's line in orthognathic profile patients. MATERIALS AND METHODS: 150 dentate subjects with age of 18-40 years with orthognathic profile were sampled. Life-size lateral digital photographs of the face with fox plane were taken in natural head position. Different angles between Eye-Ear plane and occlusal plane (OT1-OP), Eye-Ear plane and ala-superior border of tragus (OT1-AT1), Eye-Ear plane and ala-middle border of tragus (OT1-AT2) and Eye-Ear plane and ala-inferior border of tragus (OT1-AT3) were calculated using computer software package, AutoCAD 2004. From the three angles formed by the Eye-ear plane (OT1 or FH plane) and the ala-tragal lines, the one closest to the angle formed between Eye-Ear plane (OT1) and occlusal plane (OP) was used to determine the occlusal plane of orientation. The obtained results were subjected to ANOVA F test, Tukey's Honestly significant difference test, followed by Karl Pearson coefficient of correlation test. P values of less than 0.05 were taken as statistically significant. RESULTS: The mean of base line angle i.e. OT1-OP angle (11.96 +/- 4.36) was found to be close to OT1-AT2 angle (13.67 +/- 1.93) and OT1-AT3 angle (10.31 +/- 2.03), but OT1-OP angle was found to be more closer to OT1-AT3 angle. Comparison of mean angles showed that OT1-OP angle in both males (11.68) and females (12.51) is close to OT1-AT3 angle (males- 11.01, females- 11.95). CONCLUSION: The line joining from ala to the lower border of the tragus was parallel to the occlusal plane in 53.3% of the subjects. There was no influence of the sex on the level of occlusal plane.
