Background: Long-term levodopa therapy relieves the motor dysfunction associated with Parkinson's disease (PD), but has various effects on non-motor symptoms, including cognitive dysfunction, hallucinations, and affective disorders, and can exacerbate certain aspects of dementia-like cognitive dysfunction. Here, we investigated the relationship between levodopa treatment and development of dementia in patients with PD. Methods: This retrospective study analyzed 76 consecutive patients with PD who had taken levodopa between 2011 and 2015. The participants were initially free of dementia and had initial daily levodopa doses of below 600 mg. Patients who did and did not develop comorbid dementia were compared in terms of potential predictor variables, including PD onset age, sex, levodopa doses, and non-dementia comorbidities. Results: Of the 76 patients, 21 (27.6%) developed dementia, which was followed by hallucinations and insomnia. The independent predictors of incident dementia were PD onset age and second-year and third-year average levodopa doses that were higher than the first-year average levodopa dose. Patients who developed dementia had significantly higher average daily levodopa doses and levodopa dose increases over the 6-year treatment period than those who did not develop dementia. In addition, patients with higher levodopa doses were more likely to experience hallucinations. Conclusion: These results suggest that increases in levodopa doses may be associated with a greater risk of cognitive impairment in patients with PD. Therefore, motor and cognitive functions and levodopa dose increases should be evaluated regularly during long-term levodopa therapy in patients with PD.

Background: Correctional officers (COs) experience elevated rates of mental and physical ill-health as compared with other general industry and public safety occupations. The purpose of this study was to investigate demographic, mental health, job tenure, and work-family characteristics and their prospective association to burnout within and between jail officers during one year of new employment. Methods: In 2016, newly hired jail officers (N = 144) completed self-reported surveys across four time points in a one-year prospective study at a Midwestern United States urban jail. Linear mixed-effects and growth modeling examined how work-family conflict (W-FC) and depressive symptoms relate to perceptions of burnout over time. Results: Jail officer burnout increased and was related to rises in W-FC and depression symptoms. Within-person variance for W-FC (B_pooled = .52, p < .001) and depression symptoms (B_pooled = .06, p < .01) were significant predictors of burnout. Less time on the job remained a significant predictor of burnout across all analyses (B_pooled = .03, p < .001). Conclusions: Results from this study indicate that burnout increased during the first year of new employment; and increased W-FC, higher depression, and brief tenure were associated with burnout among jail COs. Future study of correctional workplace health is needed to identify tailored, multilevel interventions that address burnout and W-FC prevention and early intervention among COs.

Purpose: This study was conducted to examine the effects of a strength coaching program on nursing students' clinical competence, self esteem, and practice satisfaction. The study was designed using a nonequivalent control group pretest-post test design, and data were collected between January 7 and February 1, 2019. The participants consisted of 41, 3-year nursing students in G City who were assigned to an experimental group (n=21) or a control group (n=20). The data were analyzed using descriptive analysis, a t-test, χ² test, and paired t-test with the SPSS/WIN 21.0 program. After receiving the strength coaching program, a difference was observed in self esteem(t=5.53, p<0.038), and practice satisfaction (t=7.66, p<0.019) of the experimental group. The results of this study indicate that the strength coaching program was effective at increasing self esteem and practice satisfaction in nursing students.

This study was aimed to investigate the actual condition of the performance of the occupational health nursing services, and to analyze a main cause which affects on the execution of its duties for occupational health nurses in occupational group health service. It had been surveyed by responsed data from the 105 respondents out of 180 persons. The results were as follows : 1. In performance of occupational health nursing services by the number of assigned plant, participation rate of health examination tended to significantly increase with decreasing the number of assigned and it was observed that the visiting rate of every month was also significantly higher on touring inspection of work plant, recommendation of facility improvement for work environment, understanding the modification of manufacturing process, and inspection of welfare and sanitation facilities. 2. While they executed their nursing services according to duration of service, the more, their duration of service was, the higher, participation rate of health examination, health check in returning to work for injured workers, talk with other health managers on promoting welfare, service evaluation for a year plan, record of health statistic, and experience of first aid service were. And it was found out that the visiting rate of every month was also significantly higher on touring inspection of work plant. 3. In regard to occupational health nursing services by age, the participation rate of health examination and the experience of first aid service were significantly higher as the age increased. And also the visiting rate of every month was significantly higher on touring inspection of work plant, compared with young ones. 4. In performance of occupational health nursing services by the time required visiting plant, The shorter, the time required visiting plant was, the higher, the visiting rate of every month was, on time of health consultation for diseased workers, and inspection of welfare and sanitation facilities. 5. The subjects of health education were mostly liver disease and occupational hearing loss and video tape was used mostly in health education, monthly health education was the highest in 1-3 times(74.5%) and its duration was the highest in about 60 minutes(33.3%). 6. Vaccination of hepatitis among the specific health services was the highest accounting for 64.7%.

In a basic engineering design class, first year engineering department students learn about engineering design relevant theories and carry out simple projects in teams. By doing a group project in this subject, students develop basic skills such as creativity, teamwork, communication, and problem solving. Before, class proceeded in a way where teams were randomly configured in the beginning of semester and students began working on their project immediately. However, this research introduces a new method where at the beginning of the semester, students are assigned group assignments. Teammates are randomly chosen and constantly switched so that students get a chance to work with different people and experience diverse styles and characteristics. Then, they autonomously form into teams with people they work best and carry out their project. We present the behavior of a monkey robot that recognizes emotions as a case of applying the proposed method. The feedback from the students suggest that this proposed team forming method serves to be effective especially since students who were not aware of other students' characteristics can get to know one another better and form a productive team.

Ebstein's anomaly is a complex congenital defect of the tricuspid valve and right ventricle. Various surgical methods to repair the regurgitant tricuspid valve have been reported, and most of them depend on monocuspidalization with using the anterior leaflet. We report here on our first experience with Ebstein's anomaly in a 31-year-old female patient who underwent cone reconstruction of the tricuspid valve with using three leaflets.

This study provided longitudinal examination of the Chinese learners' acquisition of the Korean vowels. Specifically the author examined whether Korean monophthongs are acquired rapidly in early stages of learning (Flege, Munro and Skelton, 1992; Munro and Derwing, 2008) or they develop rather gradually in proportion to the learners' experience (Byee, 2001; Ellis, 2006). This study collected the Korean vowel production by 23 Chinese learners for a year, and then analysed F1 and F2 of each Korean vowel. The results showed that 1) Most of the second language (L2) vowels were rapidly improved during the first six or nine months of Korean learning before reaching the constant stage; and 2) The exact acquisition trajectories varied across the seven vowels. Specifically the vowels which were acquired in the early stage of learning were /i, e, ɨ/ for F1 and /ʌ, e, o, u/ for F2. Thus this study supports the hypothesis of Flege et al. (1992) and Munro and Derwing (2008) except the fact that each vowel showed the different learning route.

Purpose: The purpose of this study was to explore the lived experiences of new graduate nurses in personal life and in clinical setting during their first year. Methods: Eleven new graduate nurses were interviewed and the data were analyzed using the Giorgi's phenomenological method. Results: The main results of this research were negative experiences such as poor nursing skills, inability to enjoy personal life, physical exhaustion and health problems, and uncertainty of nursing values. On the other hand, there were some positive aspects on their minds: adjustmental/developmental needs, sense of responsibility, receptive capability, and proficiency with their work. They gradually found themselves being endured and changing to adapt. Conclusion: Transition from students to staff nurses is a very stressful experience for new graduate nurses. It may negatively affect their personal lives as well. However they tried to keep themselves positive to overcome their difficulties. It is necessary for them to be given time, a systematic program, and a supportive environment to adapt.
