본 연구는 오타고 운동프로그램이 낙상 경험 노인의 신체기능 및 낙상 위험도에 미치는 영향을 알아보고자 실시하였다. 낙상을 1회 이상 경험한 노인 36명을 대상으로 각각 오타고 운동프로그램 집단(실험군)과 일반적인 균형훈련집단(대조군)으로 무작위 분류하였다. 각 집단은 30분씩 주 3회, 총 8주 동안 운동을 실시하였다. 낙상의 위험성을 평가하기 위해 Tetrax를 사용하여 측정하였다. 또한, 신체기능의 측정을 위해 정적균형은 Biorescue, 동적균형은 TUG, 보행능력은 10MWT, 하지근력은 FTSST를 이용하여 측정하였다. 각 그룹 내 운동 전·후 차이를 검증하기 위하여 대응표본 t-검정(Paired T-test)을 실시하였고, 그룹 간의 비교를 위하여 독립표본 t-검정(Independent Sample T-test)을 실시하였다. 실험결과, 실험군, 대조군 모두 정적균형능력 및 동적균형능력은 운동 후 유의하게 증가하였으며, 낙상의 위험성은 감소하였다(p<.05). 하지근력 및 보행능력은 실험군에서만 운동 후 유의하게 증가하였다(p<.05). 본 연구의 결과를 종합해보면, 오타고 운동프로그램은 낙상 경험 노인의 신체기능 증진 및 낙상의 위험성이 감소에 효과적이라는 것을 알 수 있었다.

BACKGROUND/OBJECTIVES: This study aimed to examine whether the tailored home-delivered meal (HDM) services included nutrition counseling impacts alleviating self-rated frailty among low-income older adults in Korea. SUBJECTS/METHODS: Pre- and post-test were implemented on May 27 and on November 25 in 2019 during 3 weeks, respectively, before and after the 6 months intervention program. Participants completed a questionnaire measuring frailty, malnutrition, food security, depression, and underlying diseases. Initially, 136 older adults were selected as participants for this study, they were recipients of a free meal program from 2 senior welfare centers in Seoul, the final sample size of those who completed the intervention program was 117 (female 70.9%, male 29.1%). Statistical analyses were conducted with IBM SPSS package program, paired t-test and χ² test to validate the test. RESULTS: There were statistically significant differences in the score of the Tilburg Frailty Indicator (TFI) before and after receiving the tailored HDM services (pre-test 9.46, post-test 2.8, P < 0.01). The differences in the score of TFI by 3 risk groups at the pre-test decreased as a result of receiving these services. CONCLUSIONS: The tailored HDM services alleviated the self-rated frailty of low-income older adults with limited mobility in a community setting. Based on the positive outcomes this study could be applied to developing social services for aging in place.

Purpose: This study was done to examine the effects and retention of the American Heart Association (AHA)'s basic cardiac life support (BLS) training on knowledge and skills of nursing college students. Method: The study was a one group pretest-posttest experimental design. The sample included 41 junior nursing students from D college who participated in an AHA BLS course for healthcare providers in K hospital from January 18 to June 7, 2010. The instruction was based on ‘BLS knowledge and skills'. The data were analyzed with paired t-test using the SPSS/PC 12.0 win. Result: First, knowledge (t=-7.648, p=.000) and skills (t=-12.988, p=.000) were significantly increased immediately after BLS training. Second, knowledge (t=4.098, p=.000) and skills (t=50.350, p=.000) of BLS after 4 months was significantly decreased compared to right after BLS training. Conclusion: Knowledge and skills were decreased 4 months after BLS training. Therefore, retraining in BLS is required within 4 months. To maintain the knowledge and skills of BLS, appropriate renewal time and retraining programs are needed.

Objective: The Star Excursion Balance Test (SEBT) and Y-Balance Test (YBT) have been commonly applied to measure dynamic postural stability ability. These two tests are utilized interchangeably in various settings. However, they could in fact require different movements to assess dynamic postural stability, as one uses a platform and different measuring techniques than the other. The purpose of this study was to determine if there was a significant difference in the kinematic patterns in physically active population while performing the SEBT and the YBT. Method: Seventy participants performed in the Anterior (AN), Posteromedial (PM), and Posterolateral (PL) directions of the SEBT and the YBT. The kinematics of hip, knee, and ankle in sagittal plane was calculated and analyzed. Paired-sample t-tests were performed to compare joint angular displacement in the ankle, knee, and hip between the SEBT and the YBT. Results: Significant differences in angular displacement at the hip, knee, and ankle joints in the sagittal plane between performance on the SEBT and on the YBT were observed. Conclusion: Clinicians and researchers should not apply these dynamic postural control tasks interchangeably from one task to another. There appear to be kinematic pattern differences between tests in healthy physical active population.

This study investigated consumers' multi-channel behavior for fashion product purchases and compared perceived risks by channel type. A survey involving male and female college students was conducted in the Daegu and Gyungbuk area in December 2013. A total of 400 responses were analyzed using descriptive statistics, chi-square analysis, independent sample t-test, paired t-test, factor analysis, and reliability analysis. An internet shopping mall was the most frequently chosen retailer type for fashion product purchases and information searches. In addition, respondents also preferred independent branded stores, department stores, and non-branded stores. The number of retailer types for clothing item purchases ranged from 1 to 6 and the average was 3.06. The number of retailer types was significantly higher in women groups according to gender variables. Perceived risk had the highest evaluation score for internet shopping malls. Department stores were recognized as a reliable retailer type. The construct of perceived risk was shown as similar in off-line stores such as department stores, independent branded stores, and non-branded stores. Instead, the construct was differentiated from the case of internet shopping malls. Some insightful suggestions were suggested for future research and industrial marketing plans based on the results.

Background: This study examined the effects of the bridge exercise with trunk rotation on the thickness of body trunk muscles, including external oblique, internal oblique, and transverse abdominis in healthy male adults. Design: Randomized controlled trial Methods: Twenty-four men were evenly divided into a trunk rotation bridge exercise group and a basic bridge exercise group by drawing lots. The two groups performed the respective exercise for thirty minutes, three times a week for six weeks. repeated measure analysis of variance (ANOVA) was used after distinguishing between three different time points before the experiment, three weeks after the experiment, and six weeks after the experiment. The significance level was set at 0.05. In case an interaction between time and group existed, the paired t-test was used to examine the within-group difference. The independent-sample t-test was used to check the between-group difference. The significance level was set at 0.05. Results: All the men showed a significant change over time in their external oblique, internal oblique, and transverse abdominis muscles. An interaction between time and group was also found (p<0.05). Conclusion: The bridge exercise with trunk rotation causes a meaningful difference in the thickness of external oblique, internal oblique, and transverse abdominis muscles. Therefore, this study proposes the use of this exercise for lower-back stabilization in future research and clinical settings.

Purpose: This study conducted an empirical study to estimate the loss aversion rate of individual investors in the Seoul condominium market. Research design, data and methodology: A survey was conducted with Seoul residents ranging from 30's to 60's with various backgrounds. Descriptive statistical analysis and a paired sample t-test were conducted using SPSS 27.0 statistical package. Results: The results of the t-test showed that Seoul residents are indeed more sensitive to loss than gains, as pointed out in various researches related to behavioral economics. Also, the loss aversion rate associated with KRW 50 million risk was found to be 2.14. Finally, the same question was asked with KRW 100 million risk, doubled associated risk of previous question, using the same scenario, and it's been verified that the loss aversion rate increases as the associated risk or stake increases. The loss aversion rate with double risk is 2.26 which is about 5% higher than the one with KRW 50 million risk. Conclusions: This study can help many groups of people in society who need to establish rewards and punishment policies within any organization. In particular, incorporating human cognitive biases, such as loss aversion can help the South Korean government shape more effective reward and punishment policies when building rewards and punishments using taxes.
