  • In this paper, we propose a two-stage group acceptance sampling plan for generalized inverted exponential distribution under truncated life test. Median life is considered as a quality parameter. Design parameters are obtained to ensure that true median life is longer than a given specified life at certain level of consumer's risk and producer's risk. We also explore situations under which design parameters based on median lifetime can be used for other percentile points. Tables and specific examples are reported to explain the proposed plans. Finally a real data set is analyzed to implement the plans in practical situations and some suggestions are given.

  • Purpose: To examine the effects of Tai Chi exercise (TCE) on muscle strength, flexibility of low extremities, postural balance and cognition in patients with Parkinson disease (PD). Method: A nonequivalent control-group pre and post-test design was used. Of the 30 participants 15 were assigned to the experimental group and 15 to the control group. The experimental group participated in 8 weeks of TCE which included one day of exercise with instructor on site and 3 days of self-exercise at home guided by a videotape. Results: The 8 weeks of TCE were found to be significantly effective in enhancing strength of low extremities, flexibility of ankles and shoulders, time of tandem stand with eye closed and level on the K-MMSE (Korean mini mental state examination). Conclusion: These results suggest that TCE has positive effects on physical fitness and cognition in patients with PD. Research over an extended period with the TCE intervention is recommended to identify further effects.

  • This study experimentally and analytically investigates the shear behavior of corroded reinforced concrete (RC) beams repaired using steel fiber-reinforced concrete (SFRC) in the flexural zone. The experimental parameters are the corrosion degree (0%, 12%, and 17%) and the steel fiber volume in the SFRC (1.0%, 1.5%, and 2.0%). The test results reveal that corrosion degree significantly affects the shear resistance of the beams. The shear capacity of the beam with the corrosion degree of 17% was higher than that of the uncorroded beam, whereas the shear capacity of the beam with the corrosion degree of 12% was lower than that of the uncorroded beam. The shear efficiency of damaged beams can be recovered by repairing them using SFRC that contains a reasonable amount of steel fibers. In addition, two methods to estimate the shear capacity of the repaired beams are developed using the modified truss analogy and strut-and-tie models. The estimated shear capacity of the beam using the modified truss analogy model agrees well with the experimental data.

  • The purpose of this study is to examine the effects of emotional arousals of guilt versus shame on health message compliance. The study also investigates the moderation impact of two individual factors that have not been studied much in health communications, including regulatory focus and self-construal. This study employs a 2 (guilt versus shame appeals/arousals) between-subjects experiment and a survey to test the conceptual model. The context of the study is binge drinking, and the survey respondents (n = 330) are male university students in Ho Chi Minh City, Vietnam. The results confirm the positive effects of guilt and shame arousals on health message compliance. In addition, the results show moderating effects of the two individual characteristics of regulatory focus and self-construal on the relationships between guilt/shame arousals and health message compliance. The findings of this study have not only theoretical implications but also practical implications in the field of health communications. The insights could help health marketers, policymakers, and health promotion agencies to effectively develop health communications campaigns with more appealing message content (guilt versus shame) and relevant media selection (regulatory focus and self-construal).

  • This research is to the selection of optimal probability distribution as well as the estimation for design hourly factor in consideration of traffic characteristic, such as road function, lane number and AADT. To accomplish the objectives, we are applied to various probability distribution using traffic data that observed at permanent traffic count points in 2005. The parameters or the selected 14 probability distribution were estimated based on the method of maximum likelihood and the validity condition of the estimated parameter The goodness-of-fit test, such as chi-square test. was performed as well as the estimation of design hourly factor. As a result, An appropriate distributions of each case were selected : Pearson V for two lane of rural roads, LogLogistic for the four lane of rural roads, LogLogistic for the urban roads, Extreme value for recreation roads. And optimal K factor are as following : $0.1{\sim}0.2 $ for two lane of rural roads, $0.09{\sim}0.14$ for the four lane of rural roads. $0.07{\sim}0.13$ for the urban roads, $0.1{\sim}0.2$ for recreation roads.

  • This study conducted non-equality control post-design similar experimental study in order to investigate the effect of self-directed practice through self-reflection by using videos on the basic nursing performance ability, confidence in performance, learning self-efficacy, and practice satisfaction. The experimental group was 57 students and the control group was 56 students in the Department of Nursing in G region. The data was collected from April 1, 2017 to June 14, 2017. For analyzing data, the SPSS 22.0 program was used and the homogeneity test was analyzed with ${\chi}^2$ test, t-test, and Fisher's exact test. Also, independent-test was used. According to the result, all of the experimental groups including the basic nursing performance ability, confidence in performance, learning self-efficacy(t=15.304, p<.001), and practice satisfaction(t=15.304, p<.001) were improved and showed significant differences compared to the control group. As a result, it is predicted that the practice method has a positive effect on participating in self-study and it contributes to active participation by increasing learning motivation of learners. Thus, it is suggested to be applied to various practical training to improve basic nursing skills.

Method: The subjects were 45 myocardial infarction patients(22 for experimental group and 23 for the control group). Data were collected through questionnaire survey, blood test, and the treadmill test, between October 1, 1999 and December 31, 2000. As for data analyses, paired and unpaired t-test and $\chi^2$ test were adopted using the SAS program. Result: 1. The post-test revealed that increase in compliance score of health behavior was significantly higher in the experimental group than in the control group. 2. The increase in HDL cholesterol was significantly higher in the experimental group than in the control group, in the post-test. 3. The experimental group showed significantly higher duration of exercise time and maximal METs than the control group after the program. Conclusion: The above findings indicate that a cardiac rehabilitation program was effective in increasing compliance of health behaviors, serum HDL cholesterol level, duration of exercise time, and maximal METs in patients with myocardial infarction. Accordingly, we can adopt the individualized cardiac rehabilitation programs as a nursing intervention.

  • This study checks if the PITR (Person in the Rain) test can diagnose the stress caused by school-work for middle school students, in that the PITR responses correlates with the degree of stress. The subjects in the study are 483 middle school thirdgraders from 8 middle schools in Daegu city. Research tools used are an Academic Stress Scale and a PITR test. For data analysis is adopted with t-test and Chi-square test. The results from the study are as follows. First, the stress of middle students scores 2.47/4 that means that the school stress is average, and there is no gender difference in scores. Second, PITR test shows that boys draw more rain than girls, straight rain with stronger wind, hide face more, no good facial expressions more often than girls. Girls on the contrary show more stable lines, bigger puddles, place protections more appropriately. Third, those with higher academic stress use more unstable strokes, less number of or insufficient direct protections than those with less academic stress, and draw indirect protection such as umbrellas before rain or clouds. The study concludes that a PITR test can be useful in diagnosing the academic stress of middle school students.
