BackgroundHealth conservation enables elderly hemodialysis patients to maintain a positive state of well-being while undergoing treatment and maintenance of disease. This study was to identify the type of perceptions on health conservation of elderly hemodialysis patients and compare the characteristics of perceptions.MethodsThis study used an exploratory study design applying Q methodology, which is designed to research subjectivity. The study determined a population of subjective statements, the concourse, based on the preceding literature and interviews with twenty-five elderly patients over 65 years of age with hemodialysis. We chose a total of 50 statements considered to be representative of the concourse for the Q-sample. The study selected 50 elderly patients over 65 years of age with hemodialysis as the P-set. The participants provided their internal viewpoints by sorting the Q-sample items into a grid. The researchers performed an analysis using PC-QUANL program. Data were collected from June to November, 2019.ResultsType I, ‘support system-based effort’ focused on one’s own effort, positive and proactive attitude, family support, medical instructions, information, and medications. Type II, ‘skeptical life maintaining’ expressed a pessimistic future without hope, strongly negative perception on preserving health, and thus minimal effort and motivation to continue life. Type III, ‘treatment process interest’ is based on an interest in the hemodialysis process; for them, it is important to follow medical staff’s instructions, take regular medications precisely, pay attention to the results of regular monthly blood tests, and control their health. Type IV, ‘positive effort’ accepts hemodialysis positively, lives with hemodialysis, and carries out all daily life activities.ConclusionIn nursing practice, nurses need to pay attention to the perceptions on health conservation of elderly hemodialysis patients. This study can be implied as the evidence of nursing practice based on the perception on health conservation of elderly hemodialysis patients.

This study was conducted to investigate the effect of recycled paper mulching on weed occurrence, growth and yield of rice. To obtain this, a single fold of newspaper or two folds of newspaper is used. Recycled papers with basis weight of 120, 180, 250g/m2 were fabricated from recycled corrugate container. It took about from 27 to 70 days for the mulch paper to reach 50% decomposition according to type of mulch paper. Paper mulching was more effective in controlling the weed than non-mulch. The plant height and leaf area was more or less high at the control, and is similar to in that of the paper mulch treatment. The number of tiller is high at the control in the comparison with non-mulch treatment. The number of panicle for plant is similar to the control in the case of recycled paper mulch treatment too. However, but it show decreasing tendency above 50% in both the non-mulch and newspaper mulch. Newspaper give the yield of 243-305Kg/10a while, recycled paper mulch and control give yields of 448-459Kg/10a and 468Kg/10a respectively. Therefore, it could be concluded that paper mulching can not only be used as an alternative for non-herbicidal weed control but only ensure as high yield as the conventional weed control method by herbicide in transplanting rice field.

This study aimed to identify smartphone overdependency and stress’ combined effects on depression and suicide-related behaviors, such as suicidal ideation, plans, and attempts, among Korean high school students. Cross-sectional secondary data analysis was conducted using data from the 2020 Korea Youth Risk Behavior Web-based Survey. This study included 25,987 high school students. Data were analyzed using descriptive analysis, Rao-Scott chi-square test, and logistic regression based on a complex sample design. Regardless of smartphone overdependence, some stress and high stress were associated with higher depression than no stress and no smartphone overdependence. Furthermore, regardless of smartphone overdependence, some stress and high stress were associated with greater depression and suicidal ideation than no stress and no smartphone overdependence. However, only high stress was associated with suicide plans and attempts. Additionally, stress with smartphone overdependence increased the risk of depression and suicide-related behaviors, whereas the absence of stress did not significantly affect depression and suicide-related behaviors. Therefore, to prevent depression and suicide-related behaviors among high school students, continuous monitoring of and interventions to reduce stress levels should be prioritized. Moreover, as stress combined with smartphone overdependence increases the likelihood of depression and suicide-related behaviors, educational programs to prevent smartphone overdependence should be developed.

Background: This study was conducted to assess the association of pulse pressure (PP) and visceral adiposity index (VAI) by gender in Korean adults. Methods: This study used the data of 4960 adults at age ≥20 years, from the 2015 Korean National Health and Nutrition Examination Survey. Results: In the overall population (n = 4960), after adjustment for related variables and with quartile 1 of VAI as a reference, the odds ratios of high PP (PP >60 mmHg) was significantly higher in quartile 3 [1.32 (95% confidence interval [CI], 1.02-1.71)] and quartile 4 of VAI [1.40 (95% CI, 1.07-1.83)]. In women (n = 2784), the OR of high PP, with quartile 1 of VAI as a reference, was significantly higher in quartile 3 [2.36 (95% CI, 1.55-3.61)] and quartile 4 of VAI [2.70 (95% CI, 1.77-4.12)]. In men (n = 2176), high PP was not associated with the quartiles of VAI. In addition, after adjustment for related variables, the PP level was positively associated with the quartiles of VAI in the overall population (P < 0.001) and women (P < 0.001), but not in men (P = 0.316). Conclusions: VAI was positively associated with PP in Korean women, but not in Korean men.

Wearable devices such as smart glasses are considered promising assistive tools for information exchange in healthcare settings. We aimed to evaluate the usability and feasibility of smart glasses for team-based simulations constructed using a high-fidelity simulator. Two scenarios of patients with arrhythmia were developed to establish a procedure for interprofessional interactions via smart glasses using 15-h simulation training. Three to four participants formed a team and played the roles of remote supporter or bed-side trainee with smart glasses. Usability, attitudes towards the interprofessional health care team and learning satisfaction were assessed. Using a 5-point Likert scale, from 1 (strongly disagree) to 5 (strongly agree), 31 participants reported that the smart glasses were easy to use (3.61 ± 0.95), that they felt confident during use (3.90 ± 0.87), and that that responded positively to long-term use (3.26 ± 0.89) and low levels of physical discomfort (1.96 ± 1.06). The learning satisfaction was high (4.65 ± 0.55), and most (84%) participants found the experience favorable. Key challenges included an unstable internet connection, poor resolution and display, and physical discomfort while using the smart glasses with accessories. We determined the feasibility and acceptability of smart glasses for interprofessional interactions within a team-based simulation. Participants responded favorably toward a smart glass-based simulation learning environment that would be applicable in clinical settings.

Taurine has been reported to prevent cardiovascular disease and improve liver function, diabetes, and platelet function. However, there are few studies on the effects of taurine in Koreans. The purpose of this study was to investigate the effect of basal doses of taurine on blood glucose, liver disease, and lipid diseases among Korean college students. The study included a taurine intake group and a control group; each group consisted of 15 students. Taurine was administered at a standard dose of 1,000 mg for 2 weeks postprandial. All subjects were excluded from medication or other food besides meals provided by the dormitory. The liver test gamma-glutamyl transferase (GGT) in the taurine group decreased to 23.53±25.73 IU/L before intake and to 15.15±4.91 IU/L after intake (P=0.186). Lipid metabolite triglyceride (TG) was 100.42±28.33 mg/dL before intake and 80.22±17.08 mg/dL after intake (P<0.05). Total cholesterol (T-Cho), low density cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C). Consequently, taurine improved liver function and lipid metabolism. Hematologic tests showed a decrease in segmented neutrophil percentage and an increase in lymphocyte percentage. Thus, taurine also seems to be related to immunological function.
