The purpose of this study was to investigate the effect of fast food intake, choice, and satisfaction on age among 311 people living in the metropolitan area. The frequency of fast food intake was high in the 20s and 30s, and those in the 40s and over 50s were low, showing a significant difference according to age. Costs for fast food purchases mainly ranged from 5,000 won to 7,000 won. Major sources of information on choosing fast food were mainly from friends and the internet in 20s, and mass media from over 30s. Thirty-nine percent of subjects responded that their dietary habits changed after fast food intake, and the most changes was to like spicy food, followed by eating-out times increased. The factors affecting the choice of fast food were mainly easy to eat, followed by time was not influenced and taste, and taste showed significant difference according to age. Among the subjects who were worried about fast food, 30s showed mainly increase in body weight and over 50s had health problem, and a significant difference was observed according to age. For the improvements in fast food intake, subjects answered in nutrition, hygiene and price in order. Fast food brands, services, menus were the most satisfied in 30s, and 40s were the most unsatisfied, and there was a significant difference. In conclusion, the frequency of fast food intake was higher in young people, and the choice of fast food and satisfaction appeared to be significantly influenced by age. Therefore, data are required to recognize and practice a balanced diet by activating studies on the fast food intake of middle-aged and elderly people and understanding consumer changes.

Background: Normal renal function and health have been recognized as important factors in living donors after kidney donation. The purpose of this study was to evaluate the health status and health-promoting lifestyle in living donors after kidney donation. Methods: A total of 678 living-kidney donors were counted in our center from January 1990 to December 2011. Only 84 donors agreed to participate in the survey by telephone. We received consent for participation in our survey from 48 donors (57.1%). Data were collected from May to August 2013 using donor characteristics, health status, and Health Promoting Lifestyle Profile I (HPLP-I). Results: The donors were predominantly female (62.5%) and the average age was 48.9±11.8 years, and the average period after nephrectomy was 9.7±5.7 years. The characteristics of donors included ideal body weight (37.5%), overweight (37.5%) in body mass index, and good health status (81.3%). Most donors underwent an annual medical check-up (56.2%), no health problem (81.3%), and no disease (64.6%). However, one patient was treated with dialysis for renal failure due to diabetes. The total average score for HPLP-I was 128.3±13.9. Higher than average scores (116.3±19.1) were observed for the general middle-aged woman. There were statistically significant differences in self-realization and nutrition in subsection of HPLP-I. Self-realization showed a higher score for Christian (F=2.743, P=0.041) and good health (F=3.389, P=0.017). Nutrition showed a higher score for overweight, obesity (F=6.783, P=0.000), and older than 60 (F=3.854, P=0.009). Conclusions: Most living kidney donors were healthy after their donation and had relatively high scores for health-promoting lifestyle. However, one patient had a serious health problem. In addition, younger, longer period after donation, and the rare health examination of donors showed a lower health-promoting lifestyle. Designed and continuous health-care management after transplantation is needed for kidney donors.

This study aimed to analyze patients hospitalized for injuries who fell using the data from 2020 to 2021 at institution A located in Gangneung-si, Gangwon-do, using codes for causes of injury. After classifying 20 codes from W00 to W19, which are external cause codes for fall patients, the most frequently occurring W18, W01, W10, and W13 were analyzed. The external cause of injury code W18 was other falls on the same plane, with the highest frequency of S72 and Z47, S72 being a fracture of the femur, and Z47 being orthopedic follow-up treatment. The external injury code W01 was determined to be a fall on the same plane due to slipping, tripping, and tripping, and like W18, S72, a fracture of the femur, and Z47, orthopedic follow-up treatment, were frequently reported. In W10, intracranial injuries such as concussion and epidural hemorrhage due to a fall on the stairs, S06, were common. Lastly, in W13, 91% of cases occurred in people in their 40s to 70s due to falls from buildings or structures, confirming that they occur frequently in middle-aged people, Z47 had the most frequent orthopedic follow-up treatment, and S72 had a fracture of the femur. It was found to be the second most common. In this way, the frequency of falling patients was analyzed, and the age and main diagnosis code at which most falls occurred were analyzed.

Purpose: Since the start of the coronavirus disease 2019 (COVID-19) pandemic, various variants of concern have emerged. We divided the representative COVID-19 mutation period into four waves and aimed to analyze the clinical and laboratory features of children with COVID-19 from pre-mutation wave to the middle of omicron wave. Methods: We retrospectively reviewed the medical records of hospitalized patients aged ≤19 years with laboratory confirmed COVID-19. Clinical and laboratory findings during pre-mutation (February 1st 2020 to September 30th 2020), alpha/beta (October 1st 2020 to May 31st 2021), delta (June 1st 2021 to October 31st 2021), and omicron (November 1st 2021 to May 31st 2022) waves were compared. Results: Among total 827 patients, 163 (19.7%) were asymptomatic, and the frequency of fever and cough was 320 (38.7%) and 399 (48.2%), respectively. The proportion of fever ≥38.5℃ was observed to be high during the omicron wave in the age group under 12 years. Lymphopenia was observed highly in the omicron wave in the age group under 12 years, and in the delta wave in the age group older than 12 years. Neutropenia was highly observed in the delta wave in the 0-4 years age group. Conclusions: There were distinct characteristics during all epidemic waves of COVID-19. Children with COVID-19 had more frequent persistent fever during delta wave and children during the omicron wave had a higher peak fever.

This study examines the factors contributing to waterfront satisfaction among different generations, utilizing a survey on the use and perception of waterfront areas by residents of apartment houses in Tokyo's coastal region. The variables used in this study are developed through a review of existing literature, focusing on factors related to waterfront usage. Specifically, we select the proximity to the waterfront, duration of stay at the waterfront, and frequency of visits to the waterfront as key variables for investigation. In addition, the study further incorporates aspects related to waterfront recognition, such as the space, user behavior, and management status of the waterfront. Utilizing these variables, we carry out a correlation analysis to investigate the association between generational use and perception of the waterfront and their satisfaction with water-related experiences. The results identify three key factors to enhance waterfront satisfaction: First, to increase visits from both younger and older generations, improving pedestrian access to the waterfront is essential. Second, for middle-aged and older generations, creating waterfront areas closer to their residences can reduce travel distance and time, encouraging more frequent use. Third, maintaining clean and well-kept waterfront spaces is fundamental for all generations to enjoy relaxing experiences, thereby improving overall satisfaction.

Around the world, many countries experiencing the issue of shrinking cities are continually expanding high-speed rail networks to enhance regional accessibility and address imbalances. This study analyzed the effects of high-speed train operations on the age-specific population migration in South Korean municipalities from 2012 to 2019, taking into account the risk levels of shrinking cities. For this purpose, an analysis was conducted using age-specific net in-migration population as the dependent variable, employing the spatial panel autoregressive model. The research results indicated that the influence of high-speed rail on regional population inflow varies depending on the risk level of shrinking city. In other words, high-speed railway operations had positive effects on population inflow in the capital areas and some major cities, while explained population outflow in the other regions. High-speed railways particularly exerted a significant impact on the inflow of the young and middle-aged population, representing the working age, but this effect was also limited to regions with a low risk of shrinkage. The findings of this study emphasize the importance of considering planned population and industrial attraction when installing high-speed rail with the goal of achieving regional balanced development and mitigating shrinkage. The results of this study also suggest the need for subsequent research to explore factors that positively influence population structure and inflow based on the level of shrinkage risk in each region, as well as the introduction of new policies tailored to the specific situations of each local government.

Lipid metabolic disorders are commonly encountered in clinical practice. Dyslipidemia and its prevalence rate are strongly associated with the morbidity and mortality of cardiovascular disease worldwide. We conducted a genetic analysis to determine the association between genetic polymorphisms of the ABO gene in adults middle-aged (40~69 years) with dyslipidemia in the Korean population. A total of 6,750 subjects from the Korea Association REsource (KARE) were selected for this study. Using the genetic and epidemiologic data of 4,403 dyslipidemia cases and 2,347 normal controls from the KARE, single nucleotide polymorphisms (SNPs) in ABO gene were analyzed for their genetic correlation. Eleven SNPs out of the ABO gene demonstrated a statistically significant association with dyslipidemia. Among them, rs8176707 in ABO gene statistically showed the most significant correlation with dyslipidemia (P-value=0.002, odds ratio=0.82, 95% confidence interval=0.78~0.86). The minor allele of T polymorphism within the ABO intron genetic region was associated with a decreased risk of dyslipidemia. This study uncovered a significant association between genetic polymorphism in the ABO gene and dyslipidemia. This finding suggest that ABO SNPs markers have a genetic correlation with the etiology of dyslipidemia.

Introduction: Seaweed is a sustainable and underexplored source of bioactive compounds with potent anti-inflammatory activities. However, studies on the interaction between seaweed and genes on inflammation are limited. Purpose: We aimed to evaluate the relationships between seaweed consumption and the polygenic risk scores (PRS) and their interactions with high-sensitivity C-reactive protein (hs-CRP) levels. Methods: Information on seaweed consumption was collected using a food frequency questionnaire, which included laver, kelp, and sea mustard among the items consumed. A total of 31 hs-CRP-related single nucleotide polymorphisms (SNPs) were selected using genome-wide association studies and clumping analysis, and the individual PRS were calculated by weighting the effect size of each allele in the selected SNPs of 39,369 middle-aged (≥40 years) Koreans using the Korean Genome and Epidemiology Study (KoGES)-Health Examinees (HEXA) cohort data. To investigate the interaction between seaweed intake and the PRS on hs-CRP levels >1 mg/L, hazard ratios (HRs) and 95% confidence intervals (CIs) were assessed using multivariable Cox proportional hazards models. Results: During a mean follow-up period of 4.8 years, we recorded 436 patients with elevated hs-CRP levels. Women in the highest tertile of the PRS with the lowest quartile of seaweed intake had an increased incidence of elevated hs-CRP levels compared with women in the lowest tertile of the PRS with the lowest seaweed intake quartile (HR 2.34, 95% CI 1.23-4.45). No significant association was observed among the men. Conclusion: In conclusion, we identified a new interaction between the PRS, seaweed intake, and inflammation in Korean women, and this study suggests that the interaction between the identification of genetic predisposition and dietary seaweed intake may have an impact on determining the risk of developing hyperinflammation in the future.

Objective : This study aimed to categorize the lifestyles of older adults into two types - healthy and unhealthy, and use machine learning to identify the personal values that influence these lifestyles. Methods : This cross-sectional study targeting middle-aged and older adults (55 years and above) living in local communities in South Korea. Data were collected from 300 participants through online surveys. Lifestyle types were dichotomized by the Yonsei Lifestyle Profile (YLP)-Active, Balanced, Connected, and Diverse (ABCD) responses using latent profile analysis. Personal value information was collected using YLP-Values (YLP-V) and analyzed using machine learning to identify the relative importance of personal values on lifestyle types. Results : The lifestyle of older adults was categorized into healthy (48.87%) and unhealthy (51.13%). These two types showed the most significant difference in social relationship characteristics. Among the machine learning models used in this study, the support vector machine showed the highest classification performance, achieving 96% accuracy and 95% area under the receiver operating characteristic (ROC) curve. The model indicated that individuals who prioritized a healthy diet, sought health information, and engaged in hobbies or cultural activities were more likely to have a healthy lifestyle. Conclusion : This study suggests the need to encourage the expansion of social networks among older adults. Furthermore, it highlights the necessity to comprehensively intervene in individuals' perceptions and values that primarily influence lifestyle adherence.
