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.

OBJECTIVE: To compare the differences in the clinical effect on post-stroke hand spasm among the combined treatment of penetrating acupuncture and kinesiotherapy, the simple application of penetrating acupuncture and the simple application of kinesiotherapy. METHODS: A total of 105 patients with post-stroke hand spasm were randomized into a penetrating acupuncture group, a kinesiotherapy group and a combined treatment group, 35 cases in each one, of which, 2 cases were dropped out in either the combined treatment group and the penetrating acupuncture group, and 1 case dropped out in the kinesiotherapy group. The routine rehabilitation training, e.g. occupational therapy and Bobath exercise and medication were adopted in all of the three groups. In the penetrating acupuncture group, the penetrating needling technique was exerted from Hegu (LI 4) to Houxi (SI 3) and from Waiguan (TE 5) to Sidu (TE 9) on the affected side. In the kinesiotherapy group, the persistent movement or passive movement was exerted on the wrist joint, the metacarpophalangeal joints and the interphalangeal joints. In the combined treatment group, the penetrating acupuncture (the same as the penetrating acupuncture group) was exerted combined with kinesiotherapy (the same as the kinesiotherapy group). In each group, the treatment was given once a day, 30 min in each time, 6 treatments a week in total, with the interval of 1 day between the courses. The treatment for 2 weeks was as one course and 2 courses were required totally. Before and after treatment, the scores of hand spasm index, hand-wrist motor function and the activity of daily living (ADL) were compared in each group. RESULTS: After treatment, the scores of hand spasm index were reduced as compared with those before treatment in each group (<0.05) and the scores of hand-wrist motor function and ADL were increased significantly as compared with those before treatment in each group (<0.05). After treatment, the reducing degree of the score of hand spasm index in the combined treatment group was greater than the penetrating acupuncture group and the kinesiotherapy group (<0.01), and the increasing degree of the scores of hand-wrist motor function and ADL were higher than either the penetrating acupuncture group or the kinesiotherapy group (<0.01). The improvements in each index were not different statistically between the kinesiotherapy group and the penetrating acupuncture group (>0.05). CONCLUSION Compared with the simple application of either penetrating acupuncture or kinesiotherapy, the combined treatment of them achieves the significant improvements in hand spasm degree, hand wrist motor function and ADL in patients with stroke.

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.

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.

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.

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.

Testosterone is important in the physiology of various organs and tissues. The serum testosterone concentration gradually declines as one of the processes of aging. Thus, the concept of late-onset hypogonadism has gained increasing attention in the last few years. Reported symptoms of late-onset hypogonadism are easily recognized and include diminished sexual desire and erectile quality, particularly in nocturnal erections, changes in mood with concomitant decreases in intellectual activity and spatial orientation, fatigue, depression and anger, a decrease in lean body mass with associated decreases in muscle volume and strength, a decrease in body hair and skin alterations, and decreased bone mineral density resulting in osteoporosis. Among these various symptoms, sexual dysfunction has been the most common and necessary to treat in the field of urology. It is well known that a low serum testosterone level is associated with erectile dysfunction and hypoactive sexual libido and that testosterone replacement treatment can improve these symptoms in patients with hypogonadism. Recently, in addition to sexual dysfunction, a close relationship between metabolic syndrome, characterized by central obesity, insulin resistance, dyslipidemia, and hypertension, and late-onset hypogonadism has been highlighted by several epidemiologic studies. Several randomized control trials have shown that testosterone replacement treatment significantly decreases insulin resistance in addition to its advantage for obesity. Furthermore, metabolic syndrome is one of the major risk factors for cardiovascular disease, and a low serum testosterone level is closely related to the development of atherosclerosis. Presently, it is speculated that a low serum testosterone level may increase the risk for cardiovascular disease. Thus, testosterone is a key molecule in men's health, especially that of elderly men.

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 present study evaluated cognitive functions of Korean patients with essential blepharospasm by the Mini Mental State Examination - Korea (MMSE-K). METHODS: Atotal of 33 patients diagnosedwith essential blepharospasm were evaluated. Using the K-MMSEcognitive functions such as orientation, registration and recall, attention and calculation, language, comprehension, and decision were evaluated. RESULTS: All patients were alert and orientedwith an average K-MMSEscore of 25.2 +/- 4.0 points. The normal group scores were above 24 points in 25 patients (75%), suspected dementia scores were from 20 to 23 points in 5 patients (15%), and definite dementia scores were from 15 to 19 points in 3 patients (9%). Neurologic and brain imaging evaluation was performed in the 8 patients with suspected dementia or definite dementia. Among these patients, 2 were diagnosed with Parkinson's disease, 2 were shown to have a specific brain lesion on magnetic resonance imaging, and 1 was diagnosed with a stroke and treated with antiplatelet therapy. CONCLUSIONS: The K-MMSE can be a helpful tool for the early detection of cognitive dysfunction in outpatients with essential blepharospasm.
