Drought is a disaster that causes prolonged and wide scale damage. Recently, the severity and frequency of drought occurrences, and drought damage have been increased significantly due to climate change. As a result, a quantitative study of drought factors is needed to better understand and prevent future droughts. In the case of agricultural drought, several existing studies examine the economic damage caused by droughts and their causes, but these studies are not well suited to estimating crop-oriented agricultural drought damage and the factors that absolutely affect agricultural drought. This study determines which factors most affect agricultural drought. It examines meteorological factors and those related to agricultural water supplied by irrigation facilities. Rice paddy production per unit area is lower than the average from the last two years where agricultural drought occurred. We compare the relative frequency of agricultural drought impacts with irrigation facilities, effective reservoir storage, the number of water supply facilities, and the meteorological drought index such as Standardized Precipitation Index (SPI). To identify factors that affect agricultural drought, we correlate rice paddy production anomalies with irrigation water supply for the past two years. There was a high positive correlation between rice paddy production and irrigation water usage, and there was a low or moderate negative correlation between rice paddy production anomalies compared to the average of the past two years and SPI. As a result, agricultural water supply by irrigation facilities was judged to be more influential than meteorological factors in rice paddy production. This study is expected to help local governments establish policies related to agricultural drought response.

This study was conducted to investigate the stress and temporomandibular joint disorders that can affect the oral health level of college students and to identify the relationship between oral health-related quality of life. Data survey was conducted from June 3, 2021 to July 8, 2021, targeting 227 college students in some areas of Daejeon, and was analyzed using independent sample t-test, one-way ANOVA, Pearson correlation analysis, and multiple regression analysis. As a result, temporomandibular joint disorder showed a positive correlation with all stress sub-factors, and oral health-related quality of life showed a negative correlation with all stress sub-factors and temporomandibular joint disorder. Also, it was found that temporomandibular joint disorder, interpersonal stress, and values stress had an effect on oral health-related quality of life. Based on the above results, it is required to find a systematic way to improve the quality of life related to oral health by preventing stress and temporomandibular joint disorder among college students.

This study is a descriptive research study for the elderly who participated in the community's fair to identify the factors of the convergent impact of perceived health conditions, health promotion activities and dementia anxiety on the quality of health-related life. The research subjects were surveyed on 435 senior citizens aged 65 or older among the participants in the 2019 Regional Exposition, and analyzed using statistics, ANOVA, Pearson's correlation and multiple regression analysis using the SPSS 21.0 program. According to the study, the quality of life related to health affects 53.0% of the convergence factors such as perceived health conditions, health promotion activities, monthly income, and economic conditions. Therefore, various community events or programs that can lead to the reduction of dementia anxiety and the improvement of health promotion activities will have to be developed to motivate or make promotional efforts for senior citizens to participate in community events or programs, which will enable senior citizens to build social networks through the participation of various programs in the community, thereby improving health promotion activities and reducing dementia anxiety, which will improve the quality of life for senior citizens.

This study utilized data from 1,068 women aged 40-59, drawn from the 8th Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 2020, to investigate factors impacting subjective health perception and health-related quality of life. Methodologically, STATA 15.0 was employed for complex sample mean and standard deviation calculations, complex sample weighted percentages, complex sample t-tests, and multiple regression analyses. Common factors influencing both subjective health and health-related quality of life included education level, household size, depression, and stress. Age, binge drinking, and physical activity were identified as factors influencing subjective health perception. Insurance type, employment status, and sleep disorders emerged as factors impacting health-related quality of life. Recognizing middle age as a crucial transitional phase into old age, the development of health policy programs aimed at enhancing subjective health and health-related quality of life during this period is deemed essential.

This study data were collected by means of retrospective chart reviews for 111 kidney recipients at an organ transplantation center in South Korea. Data were analyzed using descriptive statistics, t-test or chi-squared test, and Pearson's correlation or Point biserial correlation. The prevalence of metabolic syndrome in our subjects was 65.8%. Metabolic syndrome was related with age, body mass index of before and after Kidney transplantation, and smoking. Study results indicate that intervention for modifying individual lifestyle behaviors is required to prevent and reduce their prevalence of metabolic syndrome after kidney transplantation.

This paper examines the changed consumer perception to internet based channel. Internet based channel has time merit, place merit, assortment merit, compatibility merit, and so on. For seller, in the mean while, it has merits in the way of diminishing physical distribution cost, promotion cost, and reaching globally in the same time. In spite of so many merits of internet based channel, there were many types complain in past. Most of all, consumers expect that it will provide low-price merit to consumer, because it doesn't need shop, warehouse, stock, etc. Based on the empirical analyses in past, it didn't work, especially to price oriented consumer's perception. But in this research, it shows changing consumer's perception. Comparing past data with current data, we found outstanding gross in price related variables figure. But, in goods delivery related factors and personal credit information related factor, consumer recognized much more negatively yet. So, we conclude that even though some factors show improved perception, there are tasks to solve. We will observe the tuning point at that time.

This study utilized the raw data from the Community Health Survey (2023) to compare differences in body function, activity, participation, environment, personal factors, and suicidal ideations between elderly individuals aged 65 and older living alone and those living with families in Korea. The study subjects consisted of 80,618 elderly individuals aged 65 and older. Cross-tabulation analysis χ²-test), independent sample t-test, and logistic regression analysis were conducted. The results indicated that for both elderly individuals living alone and those living with families, age(p<.001), smoking(p<.001), stress(p<.001), depression experience(p<.001), and falls experiences(p<.001) were risk factors that increased suicidal ideations. Conversely, educational level(p<.05), income level(p<.001), subjective health status(p<.001), social participation(p<.001), economic activity(p<.001), community environment(p<.001), and social relationships were protective factors that reduced suicidal ideations. These findings demonstrate that demographic characteristics and individual health status significantly influence suicidal ideation in the elderly, while social factors contribute to a decrease in suicidal ideation. Furthermore, considering the differences found between elderly individuals living alone and those living with families regarding hypertension and gender, differentiated interventions for suicide prevention are necessary.
