Object:This study was to investigate the difference of speech perception ability in schizophrenic patients, and depression patients in order to explore trait-dependent speech perception ability of each disorder. Methods:The speech perception ability was assessed with masked speech tracking test(MST) in schizophrenic patients(N=31), depression patients(N=25), and normal controls(N=21). The continuous performance test(CPT) and sentence repetition test(SRT) were also used for assessment of attention and working memory. Results:The schizophrenic patients showed significant impaired MST performance, compared with depressive patients and normal controls. The performances of CPT and SRT were also more impaired in schizophrenic patients. The difference of MST performances between two patient group was cancelled out after consideration of differences in CPT & SRT performances. Conclusions:These results imply that schizophrenic patients have the impaired speech perception ability compared with depressive patients and normal controls. But speech perception ability was significantly influenced with CPT and SRT. For evaluation of pure speech perception ability, the more elaborate controlled study that excluded factors such as attention, working memory and intelligence is needed.

This study investigated the effects on task performance of dyad collaboration based on young children's cognitive and social ability. The 108 5-year-old subjects were assigned to a collaborative experimental group, a comparison group working individually in sorting, writing, and making a puzzle, or a control group. Data from before and after measurements on sorting and perspective taking tasks were analyzed by t-test and ANOVA. Results showed that (1) Children working in dyad collaboration obtained significantly more improvement in their performance on both tasks than those working individually. (2) Dyads composed of a child with high level social skill but low level intelligence and a child with low levels of both showed most improvement in performance on the perspective taking task.

Purpose: The purpose of this study was to test the reliability and the validity of the Practice Environment Scale of Nursing Work Index (PES-NWI) scale when applied to Korean psychiatric nurses working in the psychiatric hospital in Korea. Methods: Data from 224 psychiatric nurses working in the 6 psychiatric hospitals in Korea were analyzed using Cronbach's ${\alpha}$, item total correlation, and exploratory factor analysis. Results: The Cronbach's ${\alpha}$ for the 27 items from the PES-NWI were .93, and the item total correlation coefficients ranged from .38 to .64. Six factors which explained 61.2 of variance in the perception of practice environment, emerged; nurse professional role and development, nurse manager ability, leadership, and support of nurses, staffing and resource adequacy, nursing foundation for quality of care, collegial nurse-physician relations, co-worker's ability and qualification. Five derived factors reconstructed, and two factors were renamed. Conclusion: Findings demonstrate that not all but 27 items from PES-NWI is a reliable and valid scale when applied to Korean psychiatric nurses working in Korea. Also findings indicate that Korean psychiatric nurses perceive practice environment differently than American nurses but have some point of similarities with Asian nurses working in the United States.

In the context of economic growth, the banking system has greatly contributed to a substantial rise in living conditions, connecting savings and investment, and economic growth. Since economic reform in 1986, Vietnam's banking system has increasingly expanded in quality and quantity of banks including state-owned, private-owned, and foreign banks. The aim of this study is to evaluate the main factors affecting employee's performance in the banking system in the case of an emerging economy of Vietnam. Using the pilot study by investigating three experts in a few banks in order to correct the questionnaires, and a mega sample data of 170 observations conducted from bank's staffs, and managers in Hanoi capital of Vietnam, empirical results demonstrate that the independent variables included in the model can explain 67% of the change of the dependent variable of employee's performance, and the rest (31%) can be explained by other reasons. Further, motivation (MO), and working ability (WA) have a positive and insignificant impact on employee's performance, reflecting that motivation, and working ability have insignificantly affected employee's performance. In contrast, four factors, namely, welfare, working environment, cooperation, and education have a positive and significant impact on employee's performance in the case of Hanoi, Vietnam.

Objectives: The purpose of this study is to investigate the knowledge, confidence and coping ability about emergency treatment, and the impact of right knowledge and confidence in practice on coping ability in part of dental hygienists. In addition, we suggest emergency treatment knowledge for develop substantive education program applicable to clinical as required data. Methods: This subjects were 259 dental hygienists working in dental setting Seoul, Gyeonggi-do from June 5 to July 20, 2016. We analyzed the data with frequency analysis, descriptive statistics, t-test, one-way ANOVA, pearson correlation coefficient, regression analysis by using SPSS. Results: Emergencies experienced by a dental hygienist in dental practice were fainting, local anesthetic allergies, and seizures. As a result of comparing the first aid knowledge, self-confidence, coping ability according to general characteristics of the study subjects, university graduation was higher than college and 3~5 years of working experience showed higher self confidence(F=3.837, p=0.023). The performance of self confidence and coping ability according to the characteristics of first aid showed high results in first aid training and dental hygienist having CPR license. Based on multiple regression analysis, confidence about emergency treatment is the biggest impact on coping ability(p<0.05). Conclusions: Dental hygienists need to develop and provide programs that can improve the ability of dental hygienists to respond appropriately and promptly in case of emergencies by recognizing the importance of first aid through conservative education.

Metro subway construction is a field that requires a great deal of professional manpower. The aging of professionals has a negative impact on both productivity and health, owing to poor working environments, heavy lifting, underground work, and other factors. To address this issue, the government is progressively revising and enforcing health management law and regulation in the construction industry. Thus, the job stress and work ability of many professional subway construction workers, who are rapidly aging, are being analyzed to ensure their safety and improve their health. In this study, the Macpa stress index of Busan Metro Subway construction workers from Sasang to Hadan line was measured by using a Macpa measurement machine, and a work ability survey was conducted by using the questionnaire that was developed by the FIOH. The independent variables were age, years of service, job position, employment type, and occupation. While, the dependent variables were the Macpa stress index and work ability. The Kruskal-Wallis test was used because it was difficult to assume that the statistics of this study represented a normal distribution. The results showed that age, job position, and employment type affected Macpa stress index and revealed that as the age of the workers increased, their stress levels increased as well. Additionally, job position and employment type affected the work ability of the metro subway construction workers. In terms of job position, the technical engineers were under a lot of stress, and whereas the managers had the best work ability. The technical engineers were more stressed than the other workers because of a poor working environment. In terms of employment type, daily workers were under more stress and lower work ability than others.
