The purpose of this study was to examine the relationship between high-intensity physical activity (work) and beverage intake frequency among Koreans. The data used in this study were obtained from the 8th Korea National Health and Nutrition Examination Survey(KNHANES) conducted in 2021. Statistical analyses, including χ²-test, and binary logistic regression, were conducted to examine group differences(p<0.05). It was found that 63.6% of the group consumed carbonated water once a week or less, and 68.6% consumed energy drinks once a week or less. These results indicated that carbonated water and energy drinks were more frequently consumed among individuals engaging in high-intensity physical activity(work), and that the majority of beverages were consumed once a week or less. Based on the findings of this study, it was hoped that the results can serve as a basis for the development of healthier alternative beverages to replace carbonated water and energy drinks during high-intensity physical activity(work). Additionally, it highlights the importance of exploring new approaches that promote health and the need for intervention programs aimed at improving health.

Objectives: This study aimed to map the incidence of acute respiratory infections (ARIs) among under-5 children in Indonesia, address the triple burden of malnutrition, and analyze the impact of malnutrition on ARIs, taking into account the environmental and wealth disparities in Indonesia. Methods: This study utilized an ecological design, analyzing aggregate data from the Indonesia Nutrition Survey, 2022. It encompassed 33 provinces and 486 districts/cities, involving a total of 334 878 children under 5 years of age. Partial least squares structural equation modeling was employed to investigate the relationships among wealth, environment, malnutrition (stunting, wasting, and underweight), and ARIs. Results: The proportion of ARI cases in Indonesia was generally concentrated in central Sumatra, the western and eastern parts of Java, and eastern Papua. In contrast, the northern part of Sumatra, central Kalimantan, central Sulawesi, and central Papua had a higher proportion of malnutrition cases compared to other regions. Negative associations were found between malnutrition and ARIs (path coefficient=-0.072; p<0.01) and between wealth and environment (path coefficient=-0.633; p<0.001), malnutrition (path coefficient=-0.399; p<0.001), and ARIs (path coefficient=-0.918; p<0.001). Conclusions: An increasing wealth index is expected to contribute to reducing ARIs, malnutrition and environmental burdens in the future. This study emphasizes the necessity for focused strategies that address both immediate health challenges and the underlying socioeconomic determinants to improve child health outcomes in the Indonesian context.

To identify daily and annual changes in outdoor airborne fungi, it is necessary to shorten the collection cycle and increase the number of measurements. In this study, measurements were performed by employing an air sampler and potato dextrose agar media on the rooftop of National Research Institute of Cultural Heritage during a period of one year (August 2018 to July 2019). The collection cycle spanned the twenty-four seasonal divisions and the collection time was 2 p.m. and 11 p.m.. Meteorological elements were collected at intervals of one hour. Furthermore, the concentration of airborne fungi was monitored and correlation analysis with meteorological elements was subsequently conducted. Obtained results indicate that the concentration of airborne fungi is found to be highest in November, autumn, night, followed by autumn, summer, winter, and spring. The concentration, type, and dominant species of airborne fungi can vary depending on factors such as rainfall, typhoons, and yellow dust (fine dust). The concentration of airborne fungi indicates a strong positive linear relationship between precipitation, number of precipitation days, and relative humidity. The concentration of airborne fungi was related to the period of increase of dead plants in terms of nutrition source, and to the high relative humidity conditions including rainfall in terms of meteorological elements.

Food irradiation is an emerging technology which offers many advantages such as reduction of microorganisms, extension of shelf-life of foods, reduction in the use of post-harvest chemicals, and destruction of insects and parasites. The commercial utilization of food irradiation, however, has been restricted because of the uncertainty of consumers' responses to it. Because success of food irradiation in the marketplace will depend upon their acceptability by consumers, this study focused on the consumers' perception and acceptance toward food irradiation in order to get basic data for commercial utilization of food irradiation and give information to consumers to help rational consumption behavior. The survey with 411 respondents living in Youngnam area was conducted during the spring of 1997 by the questionnaires. The results and implications from this study are as follows. First, consumers' knowledge about food irradiation is scanty. Two-thirds of respondents in the survey had not heard of irradiated foods and many people confused irradiation with radioactivity. In the willingness to accept food irradiation, one-third of respondents showed a wait-and-see attitude. This result indicated consumers had insufficient information about the irradiation process and nationwide education of food irradiation technology should be undertaken. Second, although the purchase and use of food are very important consumption behaviors, consumer education by mass communication has been rarely done. For the successful commercialization of food irradiation, the information provision by mass communication for the consumers should be made. Third, consumers generally worried about residual pesticide and intended to purchase irradiated foods if radioactivity was not retained in the foods. Therefore, food irradiation could be an alternative method to the use of pesticide Fourth, consumers pointed out that they wanted to extend shelf-life of milk and dairy foods, fish and seafood and to irradiate these foods. Therefore, research for the safety of irradiated foods should be continually conducted. finally, labeling for irradiated foods is needed to provide the information and to further increase public understanding. Especially, the labeling should show the definite reason why irradiation is being used. In conclusion, recently, under the circumstances that the commercial utilization of food irradiation and irradiation for the import and export products have been increased in many countries, many efforts are needed to improve the quality of irradiated foods, and prove the safety of them in Korea. In addition, consumer education for food irradiation should be given to help consumers to make decision for food purchase and use.

Purpose: In this study, eye-health inequity was investigated by analyzing the relationship between household incomes and eye-health of senior citizens. Further, this study suggested the preliminary data for establishment of public eye-health policy in order to improve low income senior citizens' life quality. Methods: The data from the 2009 Survey of Korea National Health and Nutrition Examination were analyzed in this study. The objectives of the KNHNE survey were over 65 year old group (1,668 people). Main factors of eye-health (visual acuity, cataract, pterygium, intraocular pressure, retinophathy, age-related macular degeneration, diabetic retinophathy, myopia, hyperopia, astigmatism, and anisometropia prevalence) were analyzed with t-test and chi square test. Results: Low income group revealed that refractive error rate and intraocular pressure were low, however, naked eye visual acuity and corrected visual acuity were high at 0.1 to less than 0.5. On the other hands, in the high income group, there was high prevalence of hyperopia. Cataract mainly occurred at low income group besides group which maximum corrected visual acuity was below 0.8 also highly showed cataract. Moreover, the prevalence of cataract showed that it related with smoking, drinking, occupation, and education level. Conclusions: Results revealed that there was inequity of eye-health which related with socioeconomic status of the elderly. Especially, the prevalence of cataract was correlated with life quality. Consequently, establishment of public eye-health policy seems to be required for eye-health inequity of low income senior citizens.

The purpose of this study is to compare the dental health capacity of smokers and nonsmokers. This study included 9,856 adults aged 19 years or older. The data used for analysis were obtained from the Korean National Health and Nutrition Survey for the 6th round, 1st (2013), and 2nd round (2014). Statistical analysis was performed by analysis of complex sample survey data. The demographic characteristics and results of the comparison of the dental health capacity between smokers and nonsmokers were as follows: with regard to the tissue health (T-health) index, the sex, age, and education level were statistically significant in smokers and nonsmokers. For the functioning teeth (FS-T) index, age, income, and education levels were statistically significant in smokers, while sex, age, and education level were statistically significant in nonsmokers. In smokers, the age and education level were statistically significant for present teeth (PT), sound teeth (ST), and missing teeth (MT), while in nonsmokers, the sex, age, and education level were statistically significant for the same parameters (p<0.05). A comparison of the dental health capacity between smokers and nonsmokers yielded the following findings: the T-health index was higher in smokers, while the FS-T index was higher in nonsmokers. PT and ST were higher in nonsmokers (p<0.05). The results of this study show that the dental health capacity of nonsmokers was higher than that of smokers. Therefore, a clear difference was observed in the dental health capacity of smokers and nonsmokers. The results of this study can provide objective data for nonsmoking treatment.

We conducted a survey of actual using conditions of farm-made liquid fertilizers by investigating their formulation types, materials, making processes, using methods and various beneficial effects on 29 farms certified by National Agricultural Products Quality Management Service to produce environment-friendly agricultural products in 2009. Most of the materials used to make liquid fertilizers are those that can be easily obtained around the farms. Molasses or black sugar are added as an energy source of microorganism. And leaf mold, bacterial cultures supplied by agricultural extension centers of local governments, and cultures of native microorganisms were used as microbial sources for fermenting effective microorganisms. Types of the farm-made liquid fertilizers were fermented liquid fertilizers, fermented plant juices, amino acid liquid fertilizers, calcium-liquid fertilizers, and phosphoric acid liquid fertilizers. Effects of liquid fertilizers used by the farms were found to promote plant growth by supplying nutrition, to accelerate blooming and flower bud formation, to enhance the quality of agricultural products such as increase of sugar contents and improvement of storing conditions, to induce resistance against diseases and insect pests, and to cause endurance to high temperature stress. Chemical properties of the liquid fertilizers collected were analyzed. As a result, pH and EC range showed differences according to kinds of the liquid fertilizers. Amount of macro-nutrients, such as nitrogen and phosphoric acid, in most of the collected liquid fertilizers, was found to be low. Even though the liquid fertilizers were made from same materials, their contents was found to be different depending on the making process.

Objective : The main purpose of this study was to analyze factors affecting a health related quality of life(HRQOL) in the elderly stroke patients with(Group 1) or without(Group 2) sequela. Methods : This survey performed secondary analysis with 'the fifth korea national health and nutrition examination survey', and investigated 91 elderly stroke patients over 65 years. Results : The results were as followed: HRQOL and self rated health had a significantly lower in Group 1(p<.05). In all groups, HRQOL was affected by self rated health(${\beta}=0.39$), mental health, and medical health significantly(p<.05). In group 1, HRQOL was affected by mental health(${\beta}=0.45$), self rated health significantly(p<.05). In group 2, HRQOL was affected by medical health(${\beta}=0.45$), functional health, mental health significantly(p<.05). Conclusion : In order to improve the HRQOL of stroke patients during rehabilitative therapy, it is important that early detection and early intervention of depression and suicide, which affect mental health status, are important in the case of severe aftereffects. If the patient continues to support his/her current status regardless of aftereffects, he/she can improve the HRQOL with functional recovery of the stroke patient, and finally have a positive effect on the independence of the stroke patients.
