The goal of this study is to explore different risk factors for smoking and look at the relationships between knowledge, attitudes, and behavioral intentions regarding smoking among schoolchildren, in order to reduce teenage smoking. To achieve this goal a self-administered questionaire regarding smoking was provided to schoolchildren in the 7th and 8th grades in one junior high school in Jerusalem. The schoolchildren were exposed to 10-12 hours of a smoking prevention intervention program. The questionaire focused primarily on the personal characteristics, social environment, knowledge, attitudes, practices, and behavioral intentions of the children. Crosstabs were performed on each variable to determine if significant associations exist among the different variables. The statistical computer, package, SPSS PC, was used to manipulate the data along with Chi-square test. The findings were as follows : About 11% of the children aged 12-14 have ever smoked or are smoking currently, and about 24.0% of those who ever smoked started smoking at the age of 10. Boys smoke more(p<.01), poorer students(by self-perception of school performance) smoke more, and those who had peers who were smokers were more likely to smoke(p<.05). The percentage of the children who reported that either father or mother smoked was about 30%, but no statistical association was found between parental smoking and children's smoking, although trends were noted in the expected direction, i.e. more smokers among children of smokers. Only 1.1% of the children intended to smoke in the future, and 98.0% of the children indicated that they can or they might be able to withstand social pressure. Seventy percent of the children demonstrated medium to high knowledge about smoking, Males, 8th graders, better students, and those without friends who smoke had higher social pressure showed more negative attitudes(p<.01). Those with non-smoking siblings showed more negative behavioral intentions regarding smoking(p<.01), and better students showed more negative behavioral intentions. Those who had higher knowledge scores showed more negative attitudes towards smoking, but not significantly so. Those who had very negative behavioral intentions showed highly significant negative attitudes towards smoking(p<.01).

This study was conducted to abbess dietary intake and eating habits of low-income persons aged 60 years or elder. 212 persons were surveyed between July 10 and August 17, 1978 ; 105 from the farming village of Yang-ju, Kyunggi province; and 107 from Karakdong, an area of redevlopment in the suburbs of Seoul. Results were as follows : 1 ) Family environment 84% of elderly persons surveyed, lived with their children; 13.2%, together as a couple; and 1.9%, widowed, lived alone. More than half on the households had an average monthly income of \50,000 to \30,000. The average Engel index was 61.2%. As for pocket money, 56.4% of male subjects had \l,000 to \7,000 per month, whereas 74% of female had less than \1,000. 2) Anthropometric measurements 59.9% of subjects were $70{\sim}90%$ of standard weight, 93% had an arm circumference only $60{\sim}80%$ of the standard. 3) Food and nutrient intake Carbohydrate provided 73.4 to 79.4% of total energy intake, whereas protein and fat accounted for 10.4 to 10.5% and 8.3 to 7.8%, respectively. Those over 65 years of age showed a somewhat greater dependence on carbohydrates for energy, than those under 65. Protein intake was only $42{\sim}52%$ of the recommended allowance. and the proportion of animal protein to total protein was only $2.1{\sim}9.3%$ far below the recommended allowance. Thus the protein nutrition of the subjects was proven to be inadequate qualitatively as well as quantitatively. Intake of energy and of all nutrients except vitamin A and ascorbic acid, were lower than recommended. 4) Correlational assessment The correlation coefficient between poor dental health, clinical sign score, appetite index, dietary balance and nutrient intake, was significant (0<0.01). Poor teeth, illness, and poor appetite were always associated with inadequate intake of energy and nutrients. The results of this survey reveal that many of elderly of the rural and urban poor show evidence of general malnutrition, The authours hope that this study will provide a back. ground and indicate the direction that community health and welfare programs may take to assure proper nutrition for the elderly.

Geriatric illness is increasing with aged population ratio due to a prolonged average life span. Research studies with therapeutic approach using oriental herbs have been attempted, but the very few studies of oriental herbal tea as a healthy drink have done as a health care. This study was performed to identify the effects of oriental herbal tea on the physiological function and behavioral change of elders at geriatric facility. A quasi-experimental design using a nonequivalent control group, pre-post test was used. Total 38 of elderly population (20 of experimental group and 18 of control group) was recruited. 100mL of a type of oriental herbal tea developed for this study was given to each subject 3 times a day for 30 days (from May to June 2013). The health scan analyzer and questionnaire for behavioral change were used to measure dependent variables. The data was analyzed by SPSS/WIN 18.0. After drinking the oriental herbal tea, more significant improvement on blood circulation (t=-4.466, p<.001), liver function (t=-2.855, p=.007), brain function (t=-2.545, p=.015), bone density (t=-6.125, p<.001), blood sugar (t=-4.180, p=<.001) and emotional factor (t=2.389, p=.023) as the sub-variable of behavioral change were found in the experimental group than control group. This study shows that oriental herbal tea can be effective on the physiological function and emotional relief of the elders. Therefore the tea can be utilized as an effective intervention for the health of elders in geriatric facility.

Purpose: This study aimed to identify the etiology and risk factors of community-acquired pneumonia (CAP) requiring hospitalization in Korean children during the coronavirus disease 2019 (COVID-19) pandemic. Methods: Clinical information of children admitted with CAP to Seoul National University Children's Hospital (SNUCH) between January 1, 2021, and February 28, 2022, was retrospectively collected and analyzed. In addition, the etiologic diagnosis and demographic data of children with CAP who were discharged at the other seven hospitals between January and February 2022 were collected. Pneumonia was diagnosed using strict criteria comprising clinical symptoms, physical examination findings, and chest radiographic findings. Results: Among 91 children hospitalized with CAP at SNUCH during the 14-month period, 68.4% were aged <5 years and 79.1% had underlying diseases. Among the 95 CAP cases, respiratory assistance was required in 70.5%, and the use of a ventilator was required in 20.0%. A total of five patients expired, all of whom were either immunocompromised or had underlying neurological diseases. Neurological diseases and immunosuppression were significantly correlated with respiratory assistance (P=0.003) and death (P=0.014). A total of 55% of the detected respiratory pathogens were viruses, the most common of which was rhinovirus at 35.9%. Among the 169 children hospitalized for CAP at the eight institutions, ≥1 respiratory virus was detected in 92.3%, among which respiratory syncytial virus (79.8%) was the most prevalent. Conclusions: Even during the COVID-19 pandemic, Korean children were hospitalized with CAP caused by seasonal respiratory viral pathogens. Although atypical and pyogenic bacteria were not detected, continuous clinical monitoring and further prospective studies should be conducted.

The purpose of this study was to examine the predictive factors for health promotion behaviors of older adults in rural areas. A theoretical substruction was constructed to test hypothetical models based on Pender's health promotion model. The data was collected from 199 older adults aged 65 years or older, who resided in G city, by using a structured questionnaire. The questionnaires contained items on individual characteristics, health literacy, self efficacy and health promoting behavior. The data was analyzed with a t-test, ANOVA, Pearson's correlation coefficients and hierarchical multiple regression analysis using SPSS 20.0 for Windows. The predictive factors for the health promotion behavior were the number of health information channels (β=.16, p=.031) and self efficacy (β=.53, p<.001). The total explanatory power of these factors was 30.8%. A nursing intervention plan for improving health promoting behaviors of older adults should be developed and applied, with a focus on self-efficacy and health information channels. Further longitudinal studies are needed to help confirm relevant measurement of the level of health promoting behaviors of older adults.

Objective: This study was to evaluate the health-related quality of life (HRQoL) among patients with diabetes in Korea and to compare them with the HRQoL of individuals without diabetes history. Methods: The study subjects were 17,655 adults aged over 19 who participated in the 5th Korea National Health and Nutrition Examination Survey (2010-2012). The EuroQoL-5Dimension was used to evaluate HRQoL. Chi-square test, t-test, ANOVA and multiple regression analysis were performed to test the difference of HRQoL in diabetic subjects and controls. Results: The mobility dimension was the highest reported problem: 36.4% for diabetic subjects. The proportion of any reported problem was significantly high among diabetic subjects compared with two controls in terms of mobility [reference group: diabetic subjects, chronic controls: adjusted odds ratio (aOR)=0.77, 95% confidence interval (95% CI)=0.66-0.91, healthy controls: aOR=0.61, 95% CI=0.50-0.75], self-care [reference group: diabetic subjects, chronic controls: aOR=0.68, 95% CI=0.55-0.83, healthy controls: OR=0.69, 95% CI=0.51-0.94]. and usual activities [reference group: diabetic subjects, chronic controls: aOR=0.85, 95% CI=0.72-0.99, healthy controls: OR=0.79, 95% CI=0.62-0.98]. Also, EQ-5D index were significantly low in subjects with diabetes compared to two controls. Conclusions: Subjects with diabetes had a significantly lower HRQoL compared with two controls. To improve the quality of life of diabetics, it is necessary to study various variables related to the quality of life, and develop and manage various health programs or welfare policies reflecting socio-demographic characteristics and health related features that affect the quality of life.

This study was conducted to develop and validate the social media anxiety and anger scale(SAACS), which measures emotions, especially anxiety and anger that can be contagioned to individuals, through posts and comments on social conflicts in social media. A literature search was conducted on social conflicts in social media, 12 factors(anxiety and anger about gender, crime, generation, wealth gap, politics, region) were selected. Then questions were developed after looking into previous literature and reviewing community posts and comments, and 105 preliminary questions were selected. Following the results of exploratory and confirmatory factor analysis for people aged 20 to 39 age group, SAACS was revised to 12 factors(anxiety and anger about gender, crime, generation, wealth gap, politics, and region) and 48 questions. When verifying the validity, the SAACS had a significant level of correlation with the SNS addiction tendency scale, Rosenberg self-esteem scale, Korean aggression questionnaire(K-AQ), and the state-trait anxiety inventory(STAI-X). SAACS showed no significant correlation with Korean emotional contagion scale(K-ECS). Finally, based on the results, the implications of this study and suggestions for future studies were discussed.

Purpose: The aim of the current study was to compare body mass index (BMI) with waist circumference (WC) as a predictor of elevated intraocular pressure (IOP). Methods: The subjects were consisted of 458 adults, aged 20 year or above, of one community in Kyunggi-do. Mean IOPs were stratified jointly for BMI and WC tertiles. Multi-variate linear regression analysis was also used to compare between BMI and WC. Results: Although any BMI tertiles were not associated with IOP within each tertile of WC, WC tertiles was significantly related to elevation of IOP within the third BMI tertile (${\geq}24.9kg/m^2$). After adjusting for age and sex, only WC showed significant association with IOP. In additional adjustment for lifestyle variables, both BMI and WC were significantly associated with elevation of IOP. However, the results showed the stronger association of IOP with WC than BMI, whether they were adjusted by age and sex or additionally lifestyle variables. Conclusions: These data showed that BMI and WC were positively associated with IOP. However, WC appeared to be a better indicator for higher IOP than BMI.

Objectives: This study evaluated the nutritional status and prevalence of metabolic syndrome of the people who participated in the KNHANES according to the number of household members. They were assessed by using information from the 2013~2014 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 6,088 persons aged 19 years and over participated in 2013~2014 KNHANES, and they were classified into three groups according to the number of household members (single-person, two-person, three-person & over). The dietary behavior, nutritional status, health-related factors and the prevalence of metabolic syndrome of the subjects were investigated with using information from the survey questionnaires of KNHANES. The nutrient intake data of the subjects were obtained by the 24-hour recall method and this was analyzed for evaluating the nutrition adequacy ratio and the index of nutritional quality. The prevalence of metabolic syndrome among the subjects, and according to the study groups, was estimated using the blood and physical measurement data of the subjects. Results: As for EQ-5D index available for all the health states generated by the EQ-5D descriptive system, the single-person household member was the lowest among all the household types. The index of nutrition quality for protein, crude fiber, calcium, phosphorus, potassium, riboflavin and vitamin C in the single-person household was lower than that of the two-person or the three-person and over households (p<0.001). The mean adequacy ratio of single-person households was significantly decreased compared with that of the other types of households (p<0.001). The prevalence of metabolic syndrome was higher in the single-person households than that in the multiple-person households (p<0.001). Conclusions: These results showed that dietary behaviors, nutrition status and health status might be influenced by the number of household members. The results from this study would be useful for improving Korean people's dietary life and health status by implementing evidence-based, specialized intervention for the members of diverse types of households.

Gul jeotgals (GJs) were prepared using solar salt aged for 3 years. One sample was fermented using starters, such as Bacillus subtilis JS2 and Tetragenococcus halophilus BS2-36 (each $10^6CFU/g$), and another sample was fermented without starters for 49 days at $10^{\circ}C$. Initial counts of bacilli and lactic acid bacteria (LAB) in non-starter GJ were found to be $3.20{\times}10^2$ and $7.67{\times}10^1CFU/g$ on day 0, and increased to $1.37{\times}10^3$ and $1.64{\times}10^6CFU/g$ on day 49. Those of starter GJ were found to be $2.10{\times}10^5$ and $3.30{\times}10^7CFU/g$ on day 49, indicating the growth of starters. The pH values of GJ were $5.93{\pm}0.01$ (non-starter) and $5.92{\pm}0.01$ (starter) on day 0 and decreased to $5.78{\pm}0.01$ (non-starter) and $5.75{\pm}0.01$ (starter) on day 49. Amino-type nitrogen (ANN) production increased continuously during fermentation, and $407.19{\pm}15.85$ (non-starter) and $398.04{\pm}13.73$ (starter) mg% on day 49. Clone libraries of 16S rRNA genes were constructed from total DNA extracted from non-starter GJ on days 7, 21, and 42. Nucleotide sequences of Escherichia coli transformants harboring recombinant pGEM-T easy plasmid containing 16S rRNA gene inserts from different bacterial species were analyzed using BLAST. Uncultured bacterium was the most dominant group and Gram - bacteria such as Acidovorax sp., Afipia sp., and Variovorax sp. were the second dominant group. Bacillus amyloliquefaciens (day 7), Bacillus velezensis (day 21 and 42), and Bacillus subtilis (day 42) were observed, but no lactic acid bacteria were detected. Acidovorax and Variovorax species might play some role in GJ fermentation. Further studies on these bacteria are necessary.
