To evaluate the effect of Hydrangea serrata Seringe extract on kakdoogi(Korean radish kimchi), the kakdoogi was prepared, after supplementation, with Hydrangea serrata Seringe extract(0, 1.25, 2.5 and 5%(v/w)). The quality characteristics of the kakdoogi were investigated during 7 days of fermentation at $20^{\circ}C$. The proximate components of the Hydrangea serrata Seringe leaves were 3.48% crude protein, 6.45% crude lipid, 7.98% crude fiber and 9.32% crude ash. The pH values in the samples with the extract were higher than that of both the control group and the sugar group. The total acidity levels in the sugar group was higher than that of other groups. The sugar group showed higher L value(lightness) than that of kakdoogi fermented with the extract. A value(redness) and B value(yellowness) of the supplemented kakdoogi was lower than that of the control and the sugar group on day 7. The hardness of samples with the extract was higher than that of the sugar group. And the hardness of the groups with the extract was not reduced during the fermentation period. The control group showed higher salinity than the other groups by day 4. The samples with the extract were sweeter than the control group on day 0 then the difference disappeared after day 2. Sourness of all the groups increased during the fermentation period. However the extract did not affect the hardness or overall acceptability of the kakdoogi during fermentation.

Objective: Postoperative dynamic cryo-compression (DC) therapy has been proposed as a method of reducing pain and the inflammatory response in the early postoperative period after orthopedic joint reconstruction surgery. Our aim was to analyze the analgesic efficacy of DC therapy after adult lumbar spinal surgery. Methods: DC was applied for 30 minutes every 6 hours after surgery. Pain was measured by a visual analogue scale (VAS) in the preoperative period, immediately after surgery, and every 6 hours postoperatively for the first 72 hours of the hospital stay. Patients' pain medication requirements were monitored using the patient-controlled analgesia system and patient charts. Twenty patients who received DC therapy were compared to 20 historical controls who were matched for demographic and surgical variables. Results: In the postanesthesia care unit, the mean VAS back pain score was $5.87{\pm}0.9$ in the DC group and $6.95{\pm}1.0$ (p=0.001) in the control group. The corresponding mean VAS scores for the DC vs. control groups were $3.8{\pm}1.1$ vs. $5.4{\pm}0.7$ (p < 0.001) at 6 hours postoperatively, and $2.7{\pm}0.7$ vs. $6.25{\pm}0.9$ (p<0.001) at discharge, respectively. The cumulative mean analgesic consumption of paracetamol, tenoxicam, and tramadol in the DC group vs. control group was $3,733.3{\pm}562.7mg$ vs. $4,633.3{\pm}693.5mg$ (p<0.005), $53.3{\pm}19.5mg$ vs. $85.3{\pm}33.4mg$ (p<0.005), and $63.3{\pm}83.4mg$ vs. $393.3{\pm}79.9mg$ (p<0.0001), respectively. Conclusion: The results of this study demonstrated a positive association between the use of DC therapy and accelerated improvement in patients during early rehabilitation after adult spine surgery compared to patients who were treated with painkillers only.

Objective : We attempted to discover that Ankylosing spondylitis (AS) has a comprehensive relationship with congestive heart failure and death. Methods : We used a nationwide database managed by the Korean National Health Insurance Service from 2010 to 2014. Twelve thousand nine hundred eighty-eight patients with a diagnosis of AS and 64940 age- and sex- stratified matching subjects without AS were enrolled in the AS and control groups. Incidence probabilities of 6 years congestive heart failure and death in each group were calculated. The Cox proportional hazard regression analysis was used to estimate the hazard ratio. We divided the AS and control groups into subgroups according to sex, age, income, and comorbidities. Results : During the follow-up period, 102 patients (0.79%) in the AS group and 201 patients (0.32%) in the control group developed congestive heart failure (p<0.0001). In addition, 211 (1.62%) subjects in the AS group died during the follow-up period compared to 639 (0.98%) subjects in the control group (p<0.0001). The adjusted hazard ratio of congestive heart failure and death in the AS group was 2.28 (95% confidence interval [CI], 1.80-2.89) and 1.66 (95% CI, 1.42-1.95), respectively. The hazard ratios of congestive heart failure and death were significantly increased in all of the subgroups. Conclusion : The incidence rates of congestive heart failure and death were increased in AS patients.

Objects: This study is a descriptive study to identify the factors influencing the glycated hemoglobin control in type 2 diabetes patients. Methods: This study used raw data from the third year of the National Health and Nutrition Examination Survey performed from 2015. The subjects were 285 people who were classified as type 2 diabetes patients among the 7,380 participants of the National Health and Nutrition Examination Survey. Findings: The factors influencing the glycated hemoglobin control in type 2 diabetes patients were found to be age, education level, prevalence period and sleeping time. Improvements: In type 2 diabetes patients, it is very important to have appropriate education on diabetes when they discovered the disease morbidity in the middle age rather than in the aged period and to have enough sleeping time. A practical program to help this education and training should be developed.

Purpose: The objectives of this research are to verify the development and effectiveness of a nursing student emotional competency promotion program that is important in professional nursing strategies for strengthening the psychological well-being of patients. Methods: This research was done by developing an emotional competency promotion program for nursing students according to the analysis, design, development, implementation, evaluation (ADDIE) model. Apply the program to students and evaluate their effects on their self-awareness, self-management, social awareness, relationship management and self-efficacy using a nonequivalent control group pretest-posttest design. The subjects of this research were 48 nursing students enrolled in the department of nursing of D College; 24 students were placed in the experimental group and 24 students were in the control group. The experimental group participated in the developed program from December 18, 2017 to January 12, 2018, for a total of 8 sessions. Each session was 120 minutes long. For data collection, a pretest, posttest 1 and 2 were performed using an independent t-test and repeated measure ANOVA using SPSS/WIN 22.0. Results: The experimental group who participated in the emotional competency promotion program showed higher self awareness (F=5.65, p=.005), self management (F=11.12, p<.001), social awareness (F=5.02, p=.009), relationship management (F=11.22, p<.001) and self-efficacy (F=14.24, p<.001) than the control group. These results were supported by a statistically meaningful difference in the time period and the interaction between the time period and the two groups. Conclusion: The study's findings indicate that the emotional competency promotion program developed through this study is effective at increasing the self-awareness, self-management, social awareness, relationship management and self-efficacy of nursing students.

Objectives: This study aimed to identify risk factors associated with coronavirus disease 2019 (COVID-19) mortality in pre-elderly and elderly individuals in Jakarta, Indonesia. Methods: We employed a case-control study design, utilizing secondary data from the Epidemiology Surveillance, Immunization Prevention, and Disease Control Sections of the DKI Jakarta Provincial Health Office, collected from December 2020 to January 2021. The study included 188 cases and an equal number of controls. Cases were COVID-19 patients confirmed to have died, as reported by hospitals and communities and subsequently verified by healthcare workers. Control subjects were patients who completed a 14-day isolation period and had been officially declared recovered by healthcare professionals. The dependent variable was the mortality of COVID-19 patients in the January 2021 period. The independent variables consisted of demographic data (age and sex), clinical symptoms (cough, runny nose, anosmia, diarrhea, headaches, abdominal pain, muscle pain, and nausea/vomiting), and comorbidities (hypertension, heart disease, and diabetes). Multivariate analysis was conducted using multiple logistic regression. Results: The multiple logistic regression analysis revealed several factors associated with COVID-19 fatalities in Jakarta: age of 60 years or older (odds ratio [OR], 4.84; 95% CI, 3.00 to 7.80), male (OR, 2.38; 95% CI, 2.41 to 3.68), dyspnea (OR, 3.93; 95% CI, 2.04 to 7.55), anosmia (OR, 0.13; 95% CI, 0.04 to 0.46), and heart disease (OR, 4.38; 95% CI, 1.04 to 18.46). Conclusions: The control and prevention of COVID-19 among elderly individuals require particular vigilance. When a COVID-19 case is detected within this demographic, prompt treatment and medication administration are crucial to mitigate the presenting symptoms.

Objective: This study was conducted to investigate the effects of rumen-protected biotin (RPB) on growth performance, nutrient digestibility, nitrogen utilization and plasma biochemical parameters of Liaoning cashmere goats during the cashmere fiber growing period. Methods: Sixteen 6-month-old Liaoning cashmere twin-doelings (24.8±1.20 kg) were allocated to 2 diet groups that were individually ad libitum fed 30% concentrate and 70% forage diet (dry matter [DM]) by a paired experimental design. Goats of the control group were fed the basal diet, while goats belonging to the RPB group were fed the basal diet with 10 mg RPB/d per animal. The duration of the experiment was 16 weeks with two 8-week periods. Digestibility was determined at weeks 7 and 15, and other measures were taken every four weeks. Results: Compared with the control group, the average daily gain of the RPB group increased by 10.94% (p<0.05), and the intake of neutral detergent fiber was increased (p = 0.045). There were some increasing tendencies for the intake of DM, acid detergent fiber and ether extract (p = 0.070, 0.088, and 0.070, respectively). The intake and digestibility of N tended to increase (p = 0.062 and 0.093, respectively), while the N fecal excretion percentage of N intake was decreased (p = 0.093) in the RPB compared with the control group. N retention tended to increase (p = 0.084) with the addition of adding RPB to the diet. Plasma total protein was increased (p = 0.037), whereas the urea-N concentration was decreased (p = 0.049) in the RPB diet group compared with the control diet group. The levels of propionyl-CoA carboxylase (p<0.001) and methylmalonyl-CoA (p = 0.013) were increased in the RPB group. Conclusion: Supplementation of rumen-protected biotin in the diet of cashmere goats can enhance the utilization of N and improve daily weight gain during cashmere fiber growing period.

This study investigated the growth of native ferns under indoor light intensities to identify the introduction possibility as in-door ornamental plants. Three evergreen perennial fern species used in this experiment were Coniogramme japonica (Thunb.) Diels, Woodwardia japonica (L. f.) Sm., and Cyclosorus acuminatus (Houtt.) Nakai ex H. Itô. The light intensities were adjusted to 10, 50, 100 and 200 PPFD (µmol·m^-2·s^-1) based on the measurement of the various indoor light quantities. The experiment was conducted for a total of 8 weeks, and the light period (12/12h), temperature (25±1℃), and humidity (55±3%) were maintained during the experiment. The control plant group was grown in glass greenhouse for the same period. As the result of the study, in door C. japonica showed better growth under light intensities of 100, 200 PPFD. However, withering of the plants were observed under all light intensities except the control, which causes an ornamental value decrease. This seems to be related to the increase of DIo/RC value in chlorophyll fluorescence parameters. In the W. japonica growth data, the plant height was not significantly different from the control but, the leaf number decreased more than a two-fold. Also, the formed leaves turned brown and showed a poor growth and SPAD value at 200 PPFD had decreased significantly. Growth data of C. acuminatus was not significantly different with the control at all light intensities however, withering was observed at 100 and 200 PPFD. In chlorophyll fluorescence parameters, significant decrease in Pi_Abs and increase in DIo/RC value at 200 PPFD impose that stress caused by the intense light might be the reason of the withering of the plants.
