The purpose of this study was to examine nutrition teachers' workload, job tension, and job satisfaction. Specifically, this study investigated the influence of nutrition teachers' workload and job tension on job satisfaction. A self-administered survey was distributed via online to 240 school nutrition teachers, in Korea, from July 16 to September 5, 2016. A total of 132 respondents completed the survey. The survey asked respondents for the time required for each task, job tension, job satisfaction, and demographic information. The findings of the study indicated that nutrition teachers spent most of their time on foodservice operation/ management. Among factors affecting job satisfaction, amount of work showed the lowest score. Job tension (P<0.001) of school nutrition teachers and amount of work (P<0.01) negatively affected their job satisfaction. Moreover 'kind of work' (P<0.001), 'future of career' (0.01), and 'amount of work' (0.05) were the factors significantly affecting job satisfaction. The study offers implications for governmental policies which can improve school nutrition teachers' satisfaction with their job duties.

Stereotactic cardiac radiation for ablation (radioablation) of life-threatening ventricular arrhythmia was recently introduced into clinical practice. A 76-year-old male patient with apical hypertrophic cardiomyopathy at burnout stage, who received defibrillator implantation for the secondary prevention of sudden arrhythmic death, was admitted for repeated defibrillator therapy. Radiofrequency catheter ablation was unsuccessful due to the induction of ventricular fibrillation (VF) and hemodynamically unstable sustained monomorphic ventricular tachycardia (VT). However, intracardiac activation mapping for the induced VT revealed the earliest ventricular activation at the apical aneurysm. Radioablation was performed to control VT and VF storm refractory to antiarrhythmic drug therapy. A total of 24 Gray was radiated, divided into three fractions around the apical aneurysm. The onset of electrical modulation was instantaneous and the antiarrhythmic effect was maintained for at least 6 months without significant radiation toxicities. This case suggests that radioablation may be considered as a rescue therapy for VT and VF storm refractory to other treatment modalities.

The purpose of this study was to examine restaurant customers' use of menu labeling and their perception of menu labeling attributes. Further, the study investigated relations of menu labeling use behavior, and perception of menu labeling attributes with behavioral intentions toward menu labeling. Using a self-administered survey conducted for 2 weeks from the 2nd week of October, 2015, data were collected from restaurant customers who were exposed to menu labeling over 3 months at the time of the survey. A total of 426 respondents completed the survey. Respondents were asked about use of menu labeling, usefulness, ease of understanding, accuracy, and demographic information. There was a difference in menu labeling use behavior according to age, whereas respondents aged 50 years or over showed significantly higher use of menu labeling than those in 20s (P<0.001). Perceptions of menu labeling attributes positively affected behavioral intentions towards menu labeling. While all three menu labeling attributes, ‘usefulness’, ‘ease of understanding’, and ‘accuracy’, were positive factors for behavioral intentions towards menu labeling, usefulness was the biggest attribute explaining behavioral intentions (P<0.001). The study findings offer implications that can be applied to academics, the foodservice industry, and government in an attempt to nurture a healthy eating environment through provision of nutritional information at restaurants.

BACKGROUND: Body mass index (BMI) and waist circumference (WC) are associated with cardiovascular (CV) risk factors. The aim of this study was to investigate the correlation of CV risk factors by cross-tabulating central obesity with multiple BMI categories in Korea. METHODS: A total of 328,789 adults aged 30–84 years who completed health assessments for National Health Insurance in 2012–2013 in Korea were examined. The participants were divided into two WC and five BMI groups to investigate CV risk factors, including metabolic syndrome (MetS), hypertension, diabetes, and dyslipidemia. RESULTS: The proportions of central obesity and obesity were 24.2% and 39.5% in men and 19.4% and 28.1% in women, respectively, according to the Korean Society for the Study of Obesity and World Health Organization Asia-Pacific Guideline criteria. The odds ratios (ORs) of CV risk factors in all sexes increased with increases in BMI and WC. Compared to the group with a normal WC and BMI, the adjusted ORs (95% confidence intervals) for having MetS and diabetes in the centrally obese and highest BMI group (BMI ≥30.0 kg/m²) were 35.95 (33.75–38.30) and 3.51 (3.26–3.77) in men and 29.22 (27.36–31.20) and 4.35 (4.02–4.70) in women, respectively. Participants who were centrally obese and obese (BMI ≥25.0 kg/m²) had the strongest correlation with all CV risk factors compared with those who were not centrally obese or obese. CONCLUSION: The presence of central obesity in multiple BMI categories may significantly identify individuals at increased risk of CV risk factors.

Acute appendicitis is very rare in premature neonates. Preoperative diagnosis of this condition is difficult, and then it leads to high morbidity and mortality. We report 9-day-old premature male with ruptured acute appendicitis presented with pneumoperitoneum on plain films of the abdomen. Awareness of this rare condition and possible differential diagnosis in this age group is also discussed.

PURPOSE: The purpose of this study was to identify the influences of recognition on low fertility and views of marriage on childbirth will in university students. METHODS: Participants were 190 university students in Chungchungnamdo province, Korea. The data were collected from May to October 2018 and examined using descriptive statistics, t-test, analysis of variance, Pearson correlation and multiple regression with IBM SPSS Statistics ver. 24.0. RESULTS: Childbirth will was significantly correlated with recognition on low fertility (r=0.20, p=0.002) and views on marriage (r=0.53, p<0.001). Factors associated with childbirth will were views on marriage (β=0.24, p<0.001). CONCLUSION Theses results suggests that views on marriage have important influences on childbirth will in university students. To improve childbirth will, the positive views on marriage need to be formulated in university students.

Purpose: This study aimed to examine the clinical features and determinants of macrolideunresponsive Mycoplasma pneumoniae pneumonia (MUMP) and to assess the differences in the time to fever resolution between doxycycline (DXC), tosufloxacin (TFX) and corticosteroid (CST) as second-line treatment. Methods: We retrospectively analyzed the medical records of patients under the age of 18 who were admitted to Nowon Eulji University Hospital between July 2018 and February 2020, diagnosed with mycoplasma pneumonia. Macrolide resistance was confirmed by detecting point mutations in the 23S rRNA gene. MUMP was clinically defined by persistent fever (≥38.0°C) lasting for 72 hours or more after the initiation of macrolide treatment. In cases of MUMP, patients were treated with an addition of CST, or the initial macrolide was replaced either DXC or TFX. Results: Out of 157 cases of mycoplasma pneumonia, 83 cases (52.9%) did not respond to macrolides. Patients with MUMP exhibited significantly higher C-reactive protein (CRP) levels (3.2±3.0 vs. 2.4±2.2 mg/dL, P=0.047), more frequent lobar/segmental infiltrations or pleural effusions (56.6% vs. 27.0%, P<0.001; 6.0% vs. 0.0%, P=0.032), and a higher prevalence of 23S rRNA gene mutations (96.4% vs. 64.6%, P<0.001) when compared to those with macrolide-susceptible M. pneumoniae pneumonia. In terms of second-line treatment, 15 patients (18.1%) responded to CST, 30 (36.1%) to DXC, and 38 (45.8%) to TFX. The time to defervescence (TTD) after initiation second-line treatment was significantly shorter in the CST group compared to the DXC (10.3±12.7 vs. 19.4±17.2 hours, P=0.003) and TFX groups (10.3±12.7 vs. 25.0±20.1 hours, P=0.043), with no significant difference observed between the DXC and TFX groups (19.4±17.2 vs. 25.0±20.1 hours, P=0.262). Conclusions High CRP levels, the presence of positive 23S rRNA gene mutation, lobar or segmental lung infiltration, and pleural effusion observed in chest X-ray findings were significant factors associated with macrolide unresponsiveness. In this study, CST demonstrated a shorter TTD compared to DXC or TFX. Further, larger-scale prospective studies are needed to determine the optimal second-line treatment for MUMP.

This study aimed to investigate the anti-inflammatory and wound healing effects of Corchorus olitorius cultivated in smart farms. In current study, component analysis, cell viability, anti-inflammatory activity and wound healing assay were conducted with 70% ethanol extracts of C. olitorius (ECS) grown in smart farms.Chlorogenic acid that is an indicator for C. olitorius was analyzed by high performance liquid chromatography (HPLC) and, as a result, ECS had 23.52 mg/g of chlorogenic acid. The expression of inflammatory mediators such as nitric oxide (NO) and pro-inflammatory cytokines was measured using griess reaction, enzyme-linked immunosorbent assay (ELISA) and reverse transcription polymerase chain reaction (RT-PCR). The results showed that NO, TNF-α, and IL-6 production levels were inhibited by ECS at a dose dependent manner in LPSstimulated RAW 264.7 cells. Additionally, the expression of mRNA was also suppressed by ECS at a dose dependent manner in LPS-stimulated RAW 264.7 cells. To confirm the effect of wound healing of ECS, cell proliferation and migration were examined in fibroblasts and keratinocytes. Consequently, it was confirmed that ECS showed the wound healing effect by promoting cell migration in fibroblasts and keratinocytes. These results suggested that ECS can prevent chronic wound by regulating chronic inflammation with anti-inflammatory activities and can be a new candidate material for treatment of skin wound.
