This study was conducted to identify anxiety, knowledge, possibility of infection, possibility of prevention and performance level for infection prevention among the general public according to the spread of COVID-19. Data were collected from 208 adults in their 20s and 50s from April 6th to 10th in 2020 using questionnaire. Characteristics relative to variables were measured, and analyzed using SPSS 23.0 program for technical statistics, t-test, ANOVA, and correlation. The anxiety level differed according to gender, age, marital status, and live-in partner. The Knowledge score was significantly different according to age and marital status. Possibility of infection was significantly different according to age and residential area. Performance level for infection prevention was significantly different according to gender, age, marital status, and live-in partner. However, preventive possibility was not significantly different regardless of characteristics. These findings may have implications for establishing policies that work well in preventing infectious disease. It is necessary to conduct further research comparing responses of subjects by the stages of infectious disease outbreaks. Further extended studies that include more regions and larger sample sizes are required.

Ostrinia scapulalis is one of important pests in leguminous crops, especially red bean. In order to understand the biological characteristics of the insect, we investigated the effects of temperature on development of each life stage, adult longevity and fecundity of O. scapulalis at eleven constant temperatures of 7, 10, 13, 16, 19, 22, 25, 28, 31, 34, and 36℃. Eggs and larvae successfully developed next life stage at most temperature subjected except 7, 10 and 13℃. The developmental period of egg, larva and pupa decreased as temperature increased. Lower and higher threshold temperature (TL and TH) were calculated by the Lobry-Rosso-Flandrois (LRF) and Sharpe-Schoolfield-Ikemoto (SSI) models. The lower developmental threshold (LDT) and thermal constant (K) from egg hatching to adult emergence of O. scapulalis were estimated by linear regression as 13.5℃ and 384.5DD, respectively. TL and TH from egg hatching to adult emergence using SSI model were 19.4℃ and 39.8℃. Thermal windows, i.e., the range in temperature between the minimum and maximum rate of development, of O. scapulalis was 20.4℃. Adults produced viable eggs at the temperature range between 16℃ and 34℃, and showed a maximum number, ca. 416 offsprings, at 25℃. Adult models including aging rate, age-specific survival rate, age-specific cumulative oviposition, and temperature-dependent fecundity were constructed, using the temperature-dependent adult traits. Temperature-dependent development models and adult oviposition models will be useful components to understand the population dynamics of O. scapulalis and will be expected using a basic data for establishing the strategy of integrated pest management in leguminous crops.

Objectives: This study investigates the prevalence of suicide ideation and its the related factors by gender among Korean adults. Methods: National cross-sectional data from the database of the first and second year of $5^{th}$ Korean National Health and Nutritional Examination Survey (KNHANES V-1, V-2) were used for this study. 13,165 adults (${\geq}20$ years) were included in this analysis. Results: The prevalence of suicide ideation was 9.8% for men, 18.9% for women. Renal failure, depression, melancholy, stress, perceived health status, and smoking were significant risk factors among both men and women for suicide ideation. Divorced, separated or widowed of marital status and severe physical activity were related factors of suicide ideation for men. Low educational attainment, and alcohol dependency were associated factors of suicide ideation for women. Conclusions: There was gender difference of prevalence and risk factors of suicide ideation. These gender differences should be considered for planning and implementing suicide prevention program.

This study was conducted to investigate the cross-sectional associations between dietary factors and the risk of metabolic syndrome (MetS) in 12,755 subjects (males 5,146, females 7,609) aged 19 years or above using data from the 4th (2007-2009) Korea National Health and Nutrition Examination Survey (KNHANES). The prevalence of MetS in Korean adults was 23.6% (males 26.1%, females 20.9%) with the criteria for modified National Cholesterol Education Program Adult Treatment Panel III. While males had a higher prevalence of abdominal obesity, hyperglycemia, hypertriglyceridemia, and high blood pressure than females, the prevalence of low HDL-cholesterol level was higher in females than in males. Among dietary guidelines, the response of 'yes' for asking practice of 'avoiding salty foods', and 'eating moderately and increasing physical activity for healthy weight' were significantly associated with the decreased risk of MetS in both males and in females. Especially, the risk of MetS was significantly lower in the subjects that responded the practice of all items of Korean Dietary Guidelines. Significantly negative associations with MetS were also found in the responding for practice of 'limiting consumption of alcoholic beverages' in males, and taking dietary supplements in females. Skipping breakfast was positively associated with the risk of MetS. In conclusion, dietary behaviors such as having breakfast, practice of dietary guidelines, and food consumption in moderation could modify the prevalence of MetS, and our findings could be useful for establishing guidelines for preventing MetS.

Objectives: The aim of this study was to confirm the association among the health status, health behaviors, and periodontitis according to total, age and sex in cases of adult metabolic syndrome(MetS). Methods: This cross-sectional study used collected data from the 7^th Korea National Health and Nutrition Examination Survey (KNHANES) conducted from 2016 to 2018 with 3,394 adults with MetS aged 19-79 years. The complex samples logistic regression analysis confirmed the relevant factors for periodontitis. Results:Periodontitis was diagnosed in 43.6% of all MetS cases. Diabetes (Odds Ratio [OR]=1.554), abdominal obesity (OR=1.336), current smoking (OR=2.465), past smoking (OR=1.379), and not-using oral care products (OR=1.414) were associated with periodontitis in MetS. In the age of 19-39 years with MetS group, diabetes (OR=5.379), elevated blood pressure (OR=3.975), current smoking (OR=7.430), and not using oral care products (OR=3.356) were associated with periodontitis. In the 40-79 age group, diabetes (OR=1.398), abdominal obesity (OR=1.360), current smoking (OR=2.022), and not using oral care products (OR=1.416) were associated with periodontitis. In the male MetS group, current smoking (OR=3.119), past smoking (OR=1.625), and brushing teeth more than three times (OR=0.743) were associated with periodontitis. In the female MetS group, diabetes (OR=1.733), impaired fasting glucose (OR=1.434), abdominal obesity (OR=1.479), and not using oral care products (OR=1.992) were associated with periodontitis. Conclusions: Improvement in blood sugar control, obesity, smoking cessation, and oral health education, including how to use oral care products in all individuals with MetS may result in improved oral health. In addition, improvement in elevated blood pressure in the MetS group aged under 40 years, and brushing teeth more than three times a day in the male MetS group can reduce the risk of periodontitis. Therefore, public and oral health professionals should emphasize on the relationship between age and sex during the metabolic syndrome management program and share relevant information with patients.

Reproductive behavior of the red-striped golden stink-bug, Poecilocoris lewisi Distant, was investigated in a room at 25${\pm}$1$^{\circ}C$, 60${\pm}$5％ R.H. and the 16L：8D photo regimen. Mating of adults started on the 9th day after emergence, peaked 84.5％ on the 21st day. Mating behavior of this insect was observed as follows : approach, antennal contact, mount, abdominal approach and copulation (end-to-end position). Males were quite active and produced by rubbing their body with the cages while searching for the females. However, the females responded passively during mating. Studios were further carried to see the response of virgin pairs under controlled conditions. It was observed that 69％ of pairs succeeded in mating within one hour after the lights were switched on. Females remained unreceptive for 7 days of first mating, however, males were very much positive subject to the availability of virgin females. Although the remating frequency of female was positively correlated with fertility, but a male showed lower fertility as its frequency increased.

Purpose. The purpose of this study is to analyze difference in quality of life related to health according to our country's social stratification. Methods. This study had analytical subjects as 7,992 adults(4,557 men, 3,435 women), who are included in a variable by social stratification among 15,691 people in the age group of 20~69 years old as examinees, based on the 4th Korea National Health and Nutrition Examination Survey. Results. This study obtained the following results. First, seeing the score of health-related life quality by social stratification, namely, the distribution of EQ-5D index, the new middle class(class II) was the highest(men with 0.966 point, women with 0.955 point). The agricultural self-employed class(class V) was indicated to be the lowest(men with 0.918 point, women with 0.866 point). In general, the more belonging to low social stratification led to having shown the lower aspect in EQ-5D index value. Second, as for the results of the hierarchical regression analysis, the factors of contributing to difference by social stratification in health-related quality of life were chronic disease, job stress, education, and income level in both men and women. The health behavior was grasped to be a factor of contributing only to women. Conclusions. To reduce difference in health-related quality of life according to social stratification in the future, the continuous investment is needed for supporting socially high-quality education and economic stability. The sphere of health will need to be given priority to the prevention of chronic disease and the development in effective management policy for the lower classes.

A 3D body scan measurement (SM) is used as an alternative to physical measurements (PM) as the information for designing industrial products. This study compared the mean difference (MD) between SM and PM by gender and analyzed the causes of the difference. The data used in this study were the scan measurements and physical measurements of adults aged twenty to seventy years old of the fifth Size Korea survey. The results of this study are as follows: 1. The comparison of MD between men and women for all subjects: The measurement of the significant differences between men and women were height, neck base girth, chest girth, under-bust girth, waist girth, armscye girth, back length, and foot length. The causes of difference are the difference of body shape. 2. The comparison of MD between men and women by BMI groups: Many measurements had significant differences between men and women at normal weight and overweight but underweight. Some measurements had significant differences only at a specific BMI group because the body shape difference between men and women is revealed clearly in the group. The comparison of MD between men and women by age groups: The measurements that show significant difference at more than four age groups were neck girth, chest girth, under-bust girth, waist girth, armscye girth, and foot length. The height and abdomen girth had a significant difference in the age range of 20's and 30's. There were measurements that increase MD with an increase in age; under-bust girth and lateral shoulder length for women and lateral shoulder length for men. This comparison of MD between men and women provide the correct guidelines for the use of SM.

Background: The incidence rate of brain tumors has increased more than 40% in the past 20 years, especially in adults. We aimed to study the clinical and pathological findings of central nervous system (CNS) tumor patients and to evaluate their 5 year survival rates. Materials and Methods: The archives of all patients with CNS tumors in 6 health care centers in Yazd, Iran, from 2006 to 2013, were studied. Patients data were extracted using a checklist which included age, sex, date of reference and diagnosis, date of death, clinical signs, radiography findings, pathology report, size and location of tumor, patient treatment and grade of tumor. Results: A total of 306 patient records were studied in the 8 year period. The most prevalent type of tumor was astrocytoma (n=113, 36.9%). The frequency of almost all tumor types was statistically higher in male patients (p=0.025). In most cases surgery with radiotherapy was the treatment of choice (49.3%). The most frequent symptom reported was headache (in 60.8% of patients) followed by convulsions (15.7%). Most of the tumors were located in the right hemisphere (46.1%) and the frontal and parietal lobe (26% and 12%, respectively). Radiography findings displayed edema with a nonhomogeneous lesion in majority of the patients (87%). The survival fraction of the patients with malignant tumors decreased over time (0.807 in the first year and 0.358 at the end of the $5^{th}$ year). Conclusions: Astrocytoma was the more common CNS tumor with male predominance. Overall survival rates of malignant tumors decreased over time and this was in relation with tumor grade.

This study was done to analyze the chronic diseases prevalence and dietary intake status according to the health related quality of life and to identify its significant properties. This study was conducted based on 2906 subjects ranging from 20~64 years old, out of 9704 total subjects from the 4th Korean National Health and Nutrition Survey in 2008. The average quality of life (QL) score was 0.915, where 983 subjects were below the average (low QL group) and 1923 subjects were above (high QL group). In the high QL group, there was more likely to be young, male, and with higher income and education. For high QL group, the self-related health score was high, and the subjective stress level was low. The prevalence of diabetes was significantly higher in the low QL group and anthropometric and biochemical measures were not shown differences between the two groups but waist circumference was significantly higher in the low QL group. The QL score was significantly negative correlated with the waist circumference and the body mass index. As for the recognition rate of Nutrition Guideline, there were no significant differences but high QL group had higher scores in "Eat a variety of foods", "Avoid too much Sodium", and "Enjoy meals and Eating a breakfast". Carbohydrate intake was significantly lower in the high QL group than in low QL group and the high QL group showed higher intake in legumes, meat and poultry, fruits, daily products and beverages. Overall results suggest that increased diabetes prevalence in people with low quality of life might be affected by the diets based on high carbohydrate, increased waist circumference, and lower rate of practice nutritional guideline.
