  • As the elderly population increases, the prevalence of various geriatric chronic diseases and dementia diseases is also rapidly increasing; accordingly, dementia is becoming a major concern of our society. In this study, 48 elderly patients with mild cognitive impairment located in K district were selected from a group of experimental groups in one building and a control group in one building and evaluated for blood homocysteine levels and cognitive function changes after 4,8, and 12 weeks of taking vitamin supplements. The Chi-squared test, Fisher's Exact test, independent t-test, repeated measures ANOVA, contrast test, repeated measures ANCOVA, and Wilks' lambda test were utilized to analyze the data. The results revealed that the cognitive function of the experimental group was significantly higher than that of the control group at 12 weeks (p<0.05), and so, the experimental group higher than that of the control group (p<0.01), the effect of taking vitamins was significantly increased, indicating that homocysteine was decreased relative to the control group. Therefore, vitamin supplements may prevent decreases in cognitive functions and dementia among elderly patients with mild cognitive impairment.

  • This study was conducted to evaluate the effects of a Motivation Enhancement for Smoking Cessation Program on middle school students' knowledge regarding smoking, self-efficacy, and daily amount of smoking. The study used a nonequivalent control group pre-post-test design and included 47 students who smoke from two middle schools located in city U as subjects. Subjects were separated into two groups, an experimental group with 23 students and a control group with 24 students. Data were collected from February 19, 2018 to May 11, 2018 and analyzed using the IBM SRSS/win 24.0 program to conduct a t-test, ${\chi}^2$-test, Fisher's exact test, and a paired t-test. After subjects went through the Motivation Enhancement for Smoking Cessation Program, their knowledge regarding smoking (t= 3.38, p=0.002), self-efficacy (t= -3.37, p=0.002), and their daily amount of smoking (t=3.38, p=0.002) showed significant changes. The results indicate that the Motivation Enhancement for Smoking Cessation Program is effective at increasing subjects' knowledge regarding smoking and self- efficacy while decreasing their daily amount of smoking. Therefore, to induce cessation of adolescent smoking, Motivation Enhancement for Smoking Cessation Programs tailored to each student should be held.

  • The purpose of this study was to examine the effects of an elderly people's health promotion program performed in a senior center located in J-si. Most interesting were the effects on the physical, physiological, and psychological parameters for senior center participation of the elderly. A nonequivalent control group pre-posttest design was employed. A total of 41 people living in J-si were assigned to either an experimental group (n=21) or control group (n=20). The experimental group was provided with the eight-week elderly people's health promotion program from May 1 to September 2 in 2019. The data were analyzed using SPSS/WIN 24.0 using descriptive statistics, 𝒙2-test, Fisher's exact test, and t-test. The results indicated a significant difference between the experimental group and control group with respect to the scores of the physical parameters, including right grip strength (t=-3.01, p=.004) and flexibility of the waist (t=-2.11, p=.09); the physiological parameters, including the systolic blood pressure (t=-3.02, p=.004); and psychological, including depression (t=2.42, p=.020), hopelessness (t=5.22, p<.001), and quality of life (t=4.28, p<.001). Therefore, the elderly people's health promotion program with senior center participation of the elderly is a useful nursing intervention program that can improve the right grip strength, flexibility waist, reduce the systolic blood pressure, depression and hopelessness, and improve the quality of life.

  • This study was undertaken to examine changes in the performance of nurses before and after initial cardiac arrest, and compare the performance, confidence, and satisfaction between two groups: group 1, Rapid Cycle Deliberate Practice simulation method; group 2, traditional simulation method. The participants were 122 nurses (group 1: 62, group 2: 60). Data were collected from March 18 to 29, 2019 and analyzed using the SPSS Version 23.0 program, by applying descriptive statistics, Fisher's exact test, t-test, Wilcoxon sign rank test, and Mann-Whitney U-test. Comparing the educational effects of the traditional simulation training vs. RCDP simulation training, some items of performance were significantly different (z=-2.02, p=0.044 / z=-2.42, p=0.015 / z=-3.03, p=0.002), but no difference was observed in the levels of confidence (z=0.388, p=0.699) and satisfaction (t=0.72, p=0.476) between the two groups. This study confirms that both training methods are effective teaching modules for enhancing the nurse's ability to perform resuscitation with confidence. Hence, we suggest applying the appropriate simulation method, according to the subjects included during education, and contents in the training of Advanced Life Support for nurses. Effectiveness of the modules can be ascertained by applying the RCDP simulation training method in various fields.

  • In this paper, we have formulated optimum Accelerated Life Test (ALT) plan for a parallel system with two independent components using masked data with ramp-stress loading scheme and Type-I censoring. Consider a system of two independent and non-identical components connected in parallel. Such a system fails whenever all of its components has failed. The exact component that causes the system to fail is often unknown due to cost and time constraint. For each parallel system at test, we observe its system's failure time and a set of component that includes the component actually causing the system to fail. The stress-life relationship is modelled using inverse power law, and cumulative exposure model is assumed to model the effect of changing stress. The optimal plan consists in finding out the optimum stress rate using D-optimality criterion. The method developed has been explained using a numerical example and sensitivity analysis carried out.
