PURPOSE: The purpose of this study was to construct and test a structural equation model on nursing work outcomes based on Youssef and Luthans' positive psychological capital and integrated conceptual framework of work performance.METHODS: This study used a structured questionnaire administered to 340 nurses. Data were analyzed using structural equation modeling.RESULTS: Positive psychological capital showed indirect and direct effects on job satisfaction, retention intention, organizational citizenship behavior, and nursing performance. While, the nursing work environment had direct and indirect effects on job satisfaction and nursing performance, it only had indirect effects on intention to work and organizational citizenship behavior. Additionally, a mediating effect on retention intention and organizational citizenship behavior was found between job satisfaction and nursing performance variables.CONCLUSION: The nursing organization needs to build a supportive work environment and reinforce positive psychological capital to improve nursing performance. Additionally, it needs to actively manage the necessary parameters involved in the stages of job satisfaction, retention intention, nursing performance, and organizational citizenship behavior of nurses. The findings propose the continuous management of nursing personnel based on nurses' attitude outcome, behavioral intention, behavioral outcome, and stage of role performance.

PURPOSE: To analyze the job of nursing unit managers working at women's hospital, using DACUM (developing a curriculum), DACUM is a method for analyzing job-focused competency. METHODS: This study involved a descriptive survey. A DACUM workshop was held to define women's hospital nursing unit managers' role and identify their duties and tasks. For the workshop, a committee was formed consisting of 5 women's hospital nursing unit managers. Finally, after validation, the developed contents were made into a survey asking about nursing unit manager's duties and tasks. RESULTS: Sixteen duties and 83 tasks were identified on the DACUM chart. The importance, difficulty, and frequency of the tasks were ranked in terms of A, B, and C, with A being the highest degree. Eight tasks received A's all in importance, difficulty, and frequency of performance. The 8 tasks were: ‘taking over’, ‘taking care of seriously ill patients on handover’, ‘ward rounding’, ‘analyzing and resolving demands identified during handover and patient tour’, ‘reporting patient status during rounding’, ‘promoting breast-feeding’, ‘uterine contraction, and training for breast-feeding’. The duty with the biggest determinant coefficient (DC) was ‘patients complaint management’ (DC=7.09). Based on tasks, the one with the biggest DC was ‘solving patient and patient guardian's complaints’ (DC=7.53), followed by ‘making infection control guidelines’ (DC=7.5). CONCLUSION: When expanding the nursing staff of the hospital, women's hospitals nursing unit managers also need to use administrative functions as intermediaries to focus on the operation management of the entire hospital rather than direct nursing to suit their role.

OBJECTIVE: To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) on neurological and functional recovery in patients with central cord syndrome (CCS) involving the upper extremities between the treated and non-treated sides of the treated group and whether the outcomes are comparable to that of the untreated control group. METHODS: Nineteen CCS patients were treated with high-frequency (20 Hz) rTMS over the motor cortex for 5 days. The stimulation side was randomly selected, and all the subjects received conventional occupational therapy during the rTMS-treatment period. Twenty CCS patients who did not receive rTMS were considered as controls. Clinical assessments, including those by the International Standard for Neurological Classification of Spinal Cord Injury, the Jebsen-Taylor Hand Function Test, and the O'Connor Finger Dexterity Test were performed initially and followed up for 1 month after rTMS treatment or 5 weeks after initial assessments. RESULTS: The motor scores for upper extremities were increased and the number of improved cases was greater for the treated side in rTMS-treated patients than for the non-treated side in rTMS-treated patients or controls. The improved cases for writing time and score measured on the Jebsen-Taylor Hand Function Test were also significantly greater in number on the rTMS-treated side compared with the non-treated side and controls. There were no adverse effects during rTMS therapy or the follow-up period. CONCLUSION: The results of the application of high-frequency rTMS treatment to CCS patients suggest that rTMS can enhance the motor recovery and functional fine motor task performance of the upper extremities in such individuals.

PURPOSE: This study aimed to investigate whether birth experience affects short-term memory (1,2-back task) by examining parturient and non-parturient women. METHODS: A total of 31 women were enrolled in this study, of which 16 were parturient women who had given birth within the past 2 years (mean age: 33.9±2.2 years) and 15 were non-parturient (mean age: 31.4±2.1 years). The mean age did not significantly differ between the two groups, so the effects of age were eliminated. To match the level of education between the two groups, college graduation was an inclusion criterion. A 1,2-back task consisting of six alphabets from A–F was created using the SuperLab software. For each task, there were 100 stimuli (alphabets) and 30 answers. The participants practiced the task prior to the main experiment to ensure that they adequately understood the procedure. RESULTS: The correct answer rates in the 1-back and 2-back tasks were 93.56±22.23% and 76.89±21.98%, respectively, in the non-parturient group and 95±10.04% and 80.83±13.67%, respectively, in the parturient group. The reaction time in the 1-back and 2-back tasks were 650.57±173.77 ms and 736.77±138.35 ms, respectively, in the non-parturient group and 621.91±81.90 ms and 737.5±195.99 ms, respectively, in the parturient group. There were no significant differences in the answer rates between the two groups, suggesting that parturition did not have a significant impact on the 1,2-back task performance. CONCLUSION: Birth experience does not significantly impair cognitive function. However, the findings of this pilot study are not highly reliable because of the limitations of the small sample size, degree of load, various types of working memory, and impact of hormones.

PURPOSE: In this study, effects of positive, negative, and mixed verbal feedback were examined for accuracy of self-assessment, emotional responses, self-efficacy, and perceived quality of feedback in skill performance assessment. METHODS: Participants were a convenience sample of 104 second-year nursing students who had completed their fundamentals of nursing class. Participants were assigned randomly to a positive, a negative or a mixed feedback group. All participants completed the performance measure and then received the assigned the type of feedback from an evaluator. After delivery of feedback, they assessed their own performance using the same sheet as the evaluator and completed the survey for emotional response, self-efficacy for learning, and quality of feedback. RESULTS: There were no significant differences in accuracy of self-assessment and perceived quality of feedback among the three groups (χ²=4.74, p=.094; χ²=3.30, p=.192, respectively). The negative feedback group had significantly lower self-efficacy and positive emotions and more negative emotions than the other two groups (F=9.43, p=.009; χ²=16.29, p < .001; χ²=5.69, p=.005, respectively). CONCLUSION: Negative feedback can affect emotions and motivations for learning in nursing students and may interfere with the effectiveness of feedback, so instructors should pay more attention when providing negative feedback. Mixed feedback with an effect similar to positive feedback could be an alternative.

PURPOSE: This study aimed to identify the effect of role conflict, self-efficacy, and resilience on the nursing task performance of emergency department (ED) nurses. METHODS: Data were collected from 140 ED nurses working in 6 general hospitals, using self-reporting questionnaires. Data were analyzed using SPSS 23.0, and the analyses included descriptive statistics, a t-test, an ANOVA, the Pearson's correlation coefficient test, and a stepwise multiple regression. RESULTS: Nursing task performance differed significantly in terms of the following general characteristics of the participants: age, marital status, total clinical experience, clinical experience in the ED, and position at the hospital. Nursing task performance was positively correlated with role conflict, self-efficacy, and resilience. Self-efficacy, role conflict, clinical experience in the ED, and resilience were significant predictors of nursing performance, and they accounted for 36.9% of the variance. CONCLUSION: Self-efficacy was identified as the most significant factor affecting the nursing task performance of ED nurses. Therefore, it is necessary to develop programs to improve the self-efficacy of ED nurses.

PURPOSE: This study was performed to measure the level of nursing tasks and practice environment of nursing work (PENW) perceived by nurses working on comprehensive wards or general wards, and to investigate the relationship between these two variables. METHODS: This study was a cross-sectional survey. Participants were 97 nurses working on comprehensive or general wards of one general hospital in Gyeonggido, Korea. Data were collected from October 17 to 21, 2016 using the structured questionnaires and analyzed with SPSS/PC ver 18.0 programs. RESULTS: The scores for nursing tasks (performance, importance, and knowledge) perceived by nurses working on comprehensive wards were higher than nurses on general wards. The score for PENW perceived by nurses working on comprehensive wards was significantly higher than that of nurses on general wards. For comprehensive ward nurses, there was a relationship between nursing tasks and PENW, but no relationship was found for general ward nurses. CONCLUSION: This findings show that nurses working on comprehensive wards evaluate nursing tasks and PENW higher than nurses working on general wards indicating that nursing managers should work to raise the perception of general ward nursing tasks and PENW.

OBJECTIVE: Executive dysfunction might be an important determinant for response to pharmacotherapy in obsessive-compulsive disorder (OCD), and could be sustained independently of symptom relief. The anterior cingulate cortex (ACC) has been indicated as a potential neural correlate of executive functioning in OCD. The present study examined the brain-executive function relationships in OCD from the ACC-based resting state functional connectivity networks (rs-FCNs), which reflect information processing mechanisms during task performance. METHODS: For a total of 58 subjects [OCD, n=24; healthy controls (HCs), n=34], four subdomains of executive functioning were measured using the Rey-Osterrieth Complex Figure Test (RCFT), the Stroop Color-Word Test (SCWT), the Wisconsin Card Sorting Test (WCST), and the Trail Making Test part B (TMT-B). To probe for differential patterns of the brain-cognition relationship in OCD compared to HC, the ACC-centered rs-FCN were calculated using five seed regions systemically placed throughout the ACC. RESULTS: Significant differences between the OCD group and the HCs with respect to the WCST perseverative errors, SCWT interference scores, and TMT-B reaction times (p<0.05) were observed. Moreover, significant interactions between diagnosis×dorsal ACC [S3]-based rs-FCN strength in the right dorsolateral prefrontal cortex for RCFT organization summary scores as well as between diagnosis×perigenual ACC [S7]-based rs-FCN strength in the left frontal eye field for SCWT color-word interference scores were unveiled. CONCLUSION: These network-based neural foundations for executive dysfunction in OCD could become a potential target of future treatment, which could improve global domains of functioning broader than symptomatic relief.

BACKGROUND: The law enforcement officer profession requires performance of arduous occupational tasks while carrying an external load, consisting of, at minimum, a chest rig, a communication system, weaponry, handcuffs, personal protective equipment and a torch. The aim of this systematic review of the literature was to identify and critically appraise the methodological quality of published studies that have investigated the impacts of body armour on task performance and to synthesize and report key findings from these studies to inform law enforcement organizations. METHODS: Several literature databases (Medline, CINAHL, SPORTDiscus, EMBAS) were searched using key search words and terms to identify appropriate studies. Studies meeting the inclusion criteria were critically evaluated using the Downs and Black protocol with inter-rater agreement determined by Cohen's Kappa. RESULTS: Sixteen articles were retained for evaluation with a mean Downs and Black score of 73.2 ± 6.8% (k = 0.841). Based on the research quality and findings across the included studies, this review determined that while effects of body armour on marksmanship and physiological responses have not yet been adequately ascertained, body armour does have significant physical performance and biomechanical impacts on the wearer, including: a) increased ratings of perceived exertion and increased time to complete functional tasks, b) decreased work capability (indicated by deterioration in fitness test scores), c) decreased balance and stability, and d) increased ground reaction forces. CONCLUSIONS: Given the physical performance and biomechanical impacts on the wearer, body armour should be carefully selected, with consideration of the physical fitness of the wearers and the degree to which the armour systems can be ergonomically optimized for the specific population in question.

BACKGROUND: Recently, noise coming from the neighborhood via floor wall has become a great social problem. The noise between the floors can be a cause of physical and psychological problems, and the different types of floor impact sound (FIS) may have the different effects on the human's body and mind. The purpose of this study is to assess the responses of subjective feeling, task performance ability, cortisol and HRV for the various types of floor impact. METHODS: Ten men and 5 women were enrolled in our study, and the English listening test was performed under the twelve different types of FIS, which were made by the combinations of bang machine (B), tapping machine (T), impact ball (I) and sound-proof mattress (M). The 15 subjects were exposed to each FIS for about 3 min, and the subjective annoyance, performance ability (English listening test), cortisol level of urine/saliva and heart rate variability (HRV) were examined. The sound pressure level (SPL) and frequency of FIS were analyzed. Repeated-measures ANOVA, paired t-test, Wilcoxon signed rank test were performed for data analysis. RESULTS: The SPL of tapping machine (T) was reduced with the soundproof mattress (M) by 3.9–7.3 dBA. Impact ball (I) was higher than other FIS in low frequency (31.5–125 Hz) by 10 dBA, and tapping machine (T) was higher than other FIS in high frequency (2–4 k Hz) by 10 dBA. The subjective annoyance is highest in the combination of bang machine and tapping machine (BT), and next in the tapping machine (T). The English listening score was also lowest in the BT, and next in T. The difference of salivary cortisol levels between various types of FIS was significant (p = 0.003). The change of HRV parameters by the change of FIS types was significant in some parameters, which were total power (TP) (p = 0.004), low frequency (LF) (p = 0.002) and high frequency (HF) (p = 0.011). CONCLUSIONS: These results suggest that the human's subjective and objective responses were different according to FIS types and those combinations.
