Purpose: We investigated the efficacy of electroacupuncture therapy in obese Korean women in order to make basic guidelines for the use of oriental medicine in treating obesity. Methods: Forty women were divided into two groups and each was treated 12 times: 1) one group was treated using electroacupuncture (EA) involving auricular acupuncture and physical treatment, without exercise (EA group, n=10), and 2) the other group was treated using electroacupuncture and exercise (EA plus exercise group, n=30). The EA was applied to subcutaneous fat tissue manually. Body weight was evaluated every visit and body composition was checked at the $1^{st}$ and $12^{th}$ visits. Statistical comparisons were made using SPSS13.0. We compared the weight loss, body mass index (BMI), and body composition before and after treatment using the pairedt-test. The correlations between weight loss and BMI and age were examined. Results: After the $12^{th}$ treatment, both groups showed significant reductions in body weight, BMI, body fat, and body fat percentage. The weight loss averaged 4.58${\pm}$3.87% in the EA group and 4.69${\pm}$3.10% in the EA plus Exercise group. The reduction in skeletal muscle was significant in the EA group, but not significant in the EA plus Exercise group. The speed of the weight loss was correlated with age using Pearson's correlation coefficient. Based on BMI, normal and obese subjects in the EA plus Exercise group had significant reductions in body weight, BMI, body fat, and body fat percentage; the obese subjects also had a significant reduction in skeletal muscle. Conclusion: Combined EA therapy may be effective for weight reduction. Age and BMI were related to weight loss using EA therapy.

This study was conducted to confirm the level of stress and infection prevention behavior of nursing college freshman during the COVID-19 pandemic. 119 nursing college freshmen who took remote classes because face-to-face classes were not possible due to the COVID-19 pandemic. The collected data were analyzed by descriptive statistics, Independent t-test, one-way ANOVA, and Pearson's correlation coefficient using SPSS WIN/PC 26.0 statistics program. As a result of this study, the sensitivity to stress was significantly higher when the attitude towards college life was passive (F=5.92, p=.004), and when people perceived themselves as healthy, their stress was significantly lower (t=-2.22, p=.029). In addition, those who responded that they were very uncomfortable due to activity restrictions due to COVID-19 had a significantly higher level of infection prevention behavior than those who responded that they did not feel any discomfort (F=3.51, p=.018). In a pandemic environment such as COVID-19, efforts to promote a positive attitude and awareness of health conditions are needed to reduce the stress of college freshmen and increase infection prevention behavior.

This paper presents a smartphone-attachable vascular compliance monitoring module. The proposed sensor module measures photoplethysmogram (PPG) and reconstructs an accelerated PPG waveform. The feature points are extracted from the accelerated PPG waves, and vascular compliance is estimated using these extracted features. The module is powered via the smartphone's USB terminal and transmits the acquired waveforms along with vascular compliance values through Bluetooth. The transmitted waveforms and vascular compliance value are displayed through the smartphone application. This work proposes an assessment method for consistency of PPG instrumentation, and it was implemented in a processor of sensor module. The proposed sensor module can be easily attached to smartphone that does not support PPG instrumentation, providing simple measurment and numerical analysis of vascular compliance. To verify the performance of the implemented sensor module, we acquired vascular compliance and pulse pressure data from 29 subjects. Pulse pressure, which serves as a representative indicator of vascular compliance, was obtained using a commercial blood pressure monitor. The analysis results showed that the Pearson coefficient between vascular compliance and pulse pressure was 0.778, confirming a relatively high correlation between two metrics.

In this study, a quantitative risk impact assessment is performed using an ALOHA program to identify the risks when applying ammonia as fuel for combined cycle power plants as one of the solutions of climate change. The worst and the alternative accident scenarios are established for the Sejong combined cycle power plant and the effective ranges are calculated in terms of flammability, thermal radiation, overpressure and toxicity. The analysis results show that the toxic risk is the most critical and the effective distance is highly proportional to the mixing ratio of natural gas and ammonia by showing the Pearson's correlation coefficient over 98% as 0.991, 0.987 and 0.989 for the Level Of Concern(LOC)-1, LOC-2 and LOC-3, respectively. In addition, the coefficients of linearity for LOC-1, LOC-2 and LOC-3 are calculated to 133, 70 and 29, respectively so it can be confirmed that the effective distance increases as the criterion decreases.

The study aimed to develop prediction models of primal cut yield using body measurements of Hanwoo steers in Korea. The progeny of 874 steers at Hanwoo Improvement Main Center from 2008 to 2010 were recorded. Pearson's correlation coefficients for primal cuts and other traits were estimated. Primal cuts were adjusted for slaughter date and age using the SAS GLM procedure. Afterwards, a stepwise regression was performed on each primal cut by fitting body measurement traits. An independent covariable was selected at the highest coefficient of determination with the greater fitness model using Mallows's Cp statistic. Results showed that primal cuts were significantly influenced by slaughter date (P<0.01). The age at slaughter, however, was only significant for the top round (P<0.05). There was a moderate to high correlation between chest girth and tenderloin (0.54), loin (0.74), and rib (0.80). Most primal cut percentages were negatively related to BFT. Similar negative to low positive correlations were observed for primal cut percentage and body size traits. In addition, a correlation of 0.21 was observed between rib percentage and chest girth. The regression of body measurements on the adjusted primal cuts were significant for later traits. Regression estimates revealed that wither height, body length, rump length, hip bone width, and chest girth are important for primal cut weight and percentage determination. In particular, chest girth was always important for primal cut weight estimates.
