Daegu (the city in South Korea) who visited a medical institution for medical checkup in 2016. The urine cotinine test strip (DCT-102; CLIAwaived Inc., cut-off value = 200 ng/mL) was used to classify the actual smoking status and to assess the validity of self-reported smoking status on questionnaires. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the smoking questionnaires were analyzed. Subjects testing positive in the urine cotinine test (assumed the actual current smokers) were selected. The frequency at which actual current smokers were misclassified as current non-smokers by the questionnaire was calculated. Subjects' characteristics were analyzed for possible association with any discrepancy between self-reported smoking status and urine cotinine test results.RESULTS: The smoking rates among firefighters surveyed using the smoking questionnaire and the urine cotinine test were 22.47% and 51.24%, respectively. Of the all subjects, 29.66% (n = 132) were misclassified. The sensitivity of the smoking questionnaire was 42.98%, the specificity was 99.08%, the PPV was 98.00%, and the NPV was 62.32%. In the 228 subjects classified as current actual smokers by the urine cotinine test, 57.02% (n = 130) were misclassified on the questionnaire. The misclassification rate increased with age. The degree of misclassification also increased when subjects had a history of disease.CONCLUSIONS: In present study, the validity of the smoking questionnaire for firefighters was not suitable for investigating smoking status due to low sensitivity. To increase the validity of smoking status monitoring in firefighters, consideration of the various factors like survey environment, subjects' characteristics, and occupational factors is needed.]]>

OBJECTIVES: This study examined the salinity of soups provided at childcare centers by measuring the salinity for three years and providing basic data for sodium reduction.METHODS: The soup salinity was measured using a Bluetooth salinity meter from January 2015 to December 2017 at 80 childcare foodservice establishments enrolled in the Suseong Center for Children's Foodservice Management in Daegu.RESULTS: An analysis of the soup salinity each year showed that the salinity decreased significantly from 0.48% in 2015 to 0.41% in 2017, particularly in clear soups and soybean soups compared to other soups (P < 0.05). The salinity and sodium content in seafood soups (0.45% and 179.1 mg/100 g, respectively) were highest, followed by soybean soups (0.44%, 175.2 mg/100 g), with perilla seed soups containing the lowest (0.42%, 167.2 mg/100 g) (P < 0.05). The salinity was significantly higher in institutional foodservice establishments than small foodservice establishments (P < 0.001). The salinity and sodium content were the highest in foodservice establishments with a small number of measurements, and the salinity was the lowest in foodservice establishments with salinity measurements performed an average of 151 times each year (three times a week) or more (P < 0.05). The soup salinity was low in the order of winter, spring, summer, and autumn, and the salinity decreased significantly year by year in all seasons. (P < 0.05).CONCLUSIONS: The soup salinity was significantly lower in foodservice establishments where the salinity was measured more than three times a week, indicating that continuous salinity management is effective.

PURPOSE: This study aimed to develop a model for estimating the quality of life mediated by adaptation to changes experienced after stomach cancer diagnosis and surgery in patients with gastrectomy and to verify the model based on the Cancer Survivor Adaptation Model by Naus et al. (2009) and literature reviews. METHODS: Data was collected from 297 gastric cancer patients who underwent a gastrectomy at an outpatient clinic of two university hospitals in Daegu city from May to August, 2016. The exogenous variableswere perceived gastrointestinal symptoms, self-efficacy, anxiety, social support, and spiritual well-being. The endogenous variableswere adaptation and quality of life, and adaptationwas themediating variable. For data analysis, structural equation modeling was performed using IBM SPSS 21.0 and AMOS 18.0. RESULTS: The fitness parameters of the final model showed a reasonable fit to the data. Based on R², the exogenous variables explained 73.9% of the quality of life of stomach cancer patients who underwent surgery, through the mediation of adaptation; adaptation alone explained 73.5% of quality of life. Adaptation of stomach cancer patients with gastrectomy was a factor that strongly influenced their quality of life. CONCLUSION: It is important for gastric cancer patients with gastrectomy to adapt well to changes after surgery in order to improve the quality of life. Nursing interventions to aid successful adaptation would ultimately exert positive influences and improve the patients' quality of life.

This study examined the microbiological quality of daycare center meals. Six menu items from five daycare centers in Daegu included uncooked processed foods (seasoned cucumber and lettuce salad), post-preparation after cooking processed foods (rolled omelet and seasoned soybean sprout), and cooking processed foods (panbroiled beef with oyster sauce and seasoned pork roast). Microbiological analyses were performed for the aerobic plate counts (APC), coliforms, and Escherichia coli. The analyses were conducted in July and November 2017. The mean APC and coliform count of seasoned cucumber decreased significantly from 4.71 log colony forming units (CFU)/g and 2.50 log CFU/g in July to 4.07 log CFU/g and 1.78 log CFU/g in November, respectively (P < 0.01 and P < 0.001). The APC of panbroiled beef with oyster sauce and seasoned pork roast were significantly lower in July (1.84 and 1.79 log CFU/g) than in November (2.41 and 2.28 log CFU/g) (P < 0.001). The coliform counts of panbroiled beef with oyster sauce and seasoned pork roast were significantly greater in November (2.11 and 1.62 log CFU/g) (P < 0.001). E. coli was not detected. Among the foods prepared using the three preparation processes, the post-preparation after cooking processed foods had the lowest microbial quality. The APC and coliform counts of cooking processed foods were satisfactory in July, with an acceptable rating for pan-broiled beef with oyster sauce in November. Time-temperature control and the prevention of cross-contamination are essential during meal production for food safety, regardless of the season.

BACKGROUND/AIMS: School nurses’ knowledge of inflammatory bowel disease (IBD) has not been evaluated. We aimed to investigate school nurses’ knowledge of IBD and determine whether education could improve this knowledge. METHODS: School nurses were invited to complete self-reported questionnaires on IBD. Then, IBD specialists from tertiary referral hospitals provided a 60-minute lecture with educational brochures on two occasions, with a 3-month interval. Within 6 months after the educational interventions, school nurses were asked to complete the same IBD questionnaire via e-mail. RESULTS: Among 101 school nurses who were invited to participate, 54 nurses (53.5%) who completed two consecutive questionnaires were included in this study (median age, 45 years; range, 25 to 59 years; 100% female); 11.1% and 7.4% of the study participants had no knowledge regarding ulcerative colitis and Crohn’s disease, respectively. They had heard of IBD most frequently from doctors (33.3%), followed by internet sources (25.9%). After 6 months, the number of nurses who could explain IBD to students with over 30% confidence increased from 24 (44.5%) to 42 (77.8%) (p < 0.001). Most nurses (81.5%) reported that the educational intervention was helpful for managing students with abdominal pain or diarrhea. The number of students who received IBD-related welfare services from the Daegu Metropolitan Office of Education doubled when compared with the corresponding number during the prior educational year. CONCLUSIONS: There is room for improvement in school nurses’ knowledge of IBD. A systematic educational program on IBD should be implemented for these nurses.

OBJECTIVES: This study was conducted to analyze the effect that oral health literacy of adults has on perceived oral health state and to identify the factors that affect perceived oral health status. METHODS: A self-administered questionnaire survey was distributed to 554 adults who lived in the Daegu or Gyeongbuk areas and visited dental institutions located in the Daegu area. For adults who were 60 years old or older, direct interviews were conducted. Statistical analysis was performed with t-tests, analysis of variance, and multiple regression using SPSS RESULTS: Between oral health literacy and perceived oral health status, a significant positive correlation was revealed (r=0.142, P<0.01). A significant positive correlation was revealed between oral health literacy and knowledge (r=0.397, P<0.01). A significant but weakly positive correlation was revealed between oral health knowledge and perceived oral health status (r=0.086, P<0.05). To identify factors affecting perceived oral health status, multiple regression analysis was conducted, and the result showed that oral health literacy was a statistically significant factor (β=0.105, p<0.05). Among general characteristics, age was a statistically significant negatively affecting factor, as it showed a negative relationship with perceived oral health status (β=−0.140, P=0.001, adjusted R2=0.049). CONCLUSIONS: When these study results are taken into consideration, oral health literacy is a factor affecting perceived oral health status, and as such, oral health literacy of the research targets should be taken into consideration when implementing oral health education to promote oral health.

Hesitation wounds are tentative, superficial incised wounds around the fatal wound(s). This study aimed to investigate the frequency and characteristic features of hesitation wounds including ordinary incised wounds and knife tip injuries as hesitation marks from the autopsy cases of suicides using sharp force instruments. The subjects were 478 cases out of 3,131 suicide cases autopsied at the Department of Forensic Medicine, School of Medicine, Kyungpook National University in Daegu, from August, 2001 to 2013. 48 cases (approximately 10%) were suicides using sharp force instruments. In 27 cases (56.3%), the sharp force was successfully applied causing suicide; 17 cases (35.4%) were so called complex suicide cases, in which two or more different methods including sharp force injury were used; and the 4 remaining cases were suicides caused by other reasons. Overall hesitation wounds had a high frequency of 33/48 cases (68.8%). The frequency of cases in which knife tip injuries were found was lower, appearing in 13/33 cases (39.3%). The most preferred sites of knife tip injuries were the abdomen (9 cases), neck (4 cases), chest (3 cases), and face (1 case) in these 13 cases, including several overlapped cases. The average number of knife tip injuries was 14.6. A total of 88.2% of knife tip injuries was found near the incised hesitation wounds or fatal wounds. In conclusion, knife tip injuries may be a significant factor in identifying hesitation wounds, and they should be precisely examined and evaluated during autopsies to determine the manner of death.

OBJECTIVES: This study examined the status of children's favorite foods intake and the relationship with the policy environment based on the Special Act on Safety Control of Children's Dietary Life for suggesting a supportive policy strategy. METHODS: The subjects were 4th grade students (n=1,638) in elementary school from 45 schools collected from seven areas (Seoul, Daegu, Daejeon, Gyeonggi, Chungnam, Jeonbuk, and Gyeongnam). The children participated in a self-administered questionnaire survey in class under the supervision of the teacher. The questionnaire consisted of items, such as social demographic characteristics, frequency of intake of the children's favorite foods, and policy cognition. A t-test and ANOVA were applied to explore the relationship between the frequency of children's favorite foods intake and policy cognition. The survey was implemented from August 2016 to September 2016. RESULTS: For the boys, the frequency of ‘high-calorie low nutrient foods intake’ (HCLN) was significantly higher than that of the girls (p<0.01). For the children who received information on their favorite foods from the internet, the frequency of HCLN was higher than the other sources (p<0.01). The time of TV viewing and computer usage, and smartphone usage was associated with a higher frequency of HCLN, and a lower healthy favorite food intake (all p<0.001). The intake frequency of healthy favorite foods indicated a positive correlation with the policy cognition, including policy perception, usefulness, necessity and buying intention, and educational experience. CONCLUSIONS: This study showed a correlation with the frequency of children's favorite foods intake and policy. In particular, the frequency of children's healthy favorite foods intake indicated a meaningful relationship with the policy than the frequency of HCLN. This study also found that the consumption of children's healthy favorite foods was positively correlated with the educational experience. To develop a supportive policy for a good dietary environment for children, there is a need to focus on how to collaborate with multiple levels of influences, such as the national level, school level, and family.
