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.

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.

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.

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: 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.

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).

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.
