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 was conducted from April 2020 to June of the same year to identify the working skills, quality of life and depression on occupational therapists working at medical institutions in Gwangju, Jeollabuk-do and Jeollanam-do. Each function was evaluated using the WAI(Work Ability Index), the Korean version of WHOQOL and PHQ-9(Patient Health Questionnaire-9 Korean version) to evaluate the working ability, quality of life and depression level of depression. Studies have shown mo statistically significant differences in all areas of work capability, quality of life, or depression, depending on general characteristics. The correlation between work tretment worker's work ability, quality of life and depression showed a positive correlation between work ability and quality of life and a strong nehative correlation between quality of life and depression. This is a tesult of improved working ability, which improves the quality of life and lowers the level of depression if there is a positive change in the quality of life. It is hoped that research will be conducted considering the work ability and quality of life of occupational therapists who play an important role in rehabilitation and ways to reduce depression.

For knowing the effects of aging on conversational skills in daily communication, this paper studied for the conversational turn-taking skills, working memory and naming ability on healthy elderly adults over 65 ages. 85 elderly adults participated in this study, which divided into four groups by ages. Speech samples were collected in natural conversation. Memorization of numbers, mental calculation, repetition of words were administered for working memory test. K-BNT was used for the naming ability. One-way ANOVA analysis was used for the comparison of conversational turn-taking skills among four groups. We analyzed the correlation between conversational skills, working memory and naming ability. The results were as follows: first, there were a significant difference in conversational turn-taking skills by age, but not by gender. There was a significant difference in 'Turn-Taking Frequency' and 'Total Utterance Frequency' among four groups. The same results were shown in the scores of females within three groups(exclude groups over 85D)(p<.01). Second, there was a significant correlation between 'rates of maintenance' and 'naming ability'. In addition, it was found that the naming test predicted 'rates of maintenance' skills. The results of this study suggest that word-retrieval ability will be helpful to enhance functional communication skills in aging old adults.

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.

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.
