PURPOSE: This study was designed to examine the relation of trait anger and anger expression to blood pressure, cholesterol, and depression in middle-aged Korean women. METHODS: This descriptive correlational design was conducted using a convenient sample taken from the health center of K University Hospital located in Kyungki province, Korea. The subjects were 252 women aged 40 to 64 years. Spielberger's state trait anger expression inventory - Korean version and Beck's depression inventory were used for measuring trait anger, state anger, anger expression and depression. Data was analyzed by descriptive statistics, t-test, Pearson correlation, two-way ANOVA, and cluster analysis using a pc-SAS program. RESULTS: The anger expression types by cluster analysis were Anger out/in type, Low anger expression type, and Anger control type. The level of cholesterol and depression were significantly higher in women with high anger in and high trait anger. In addition, the level of depression was significantly higher in women with a high anger temperament. CONCLUSIONS: Trait anger and anger in might be related to cholesterol and depression in women. However, this study does not reveal the relation between blood pressure and trait anger and anger expression.

OBJECTIVE: A radial arm maze (RAM) is an essential tool for assessing spatial learning and memory. Although this tool is widely used to study deficits in spatial memory in animal models, it has several restrictions that prevent its adaptation to human research and training. Therefore, we developed a head-mounted-display RAM (HMD-RAM) program for humans and verified its validity by comparing it to the results obtained by previous RAM studies. We also compared the HMD and a flat monitor as experimental devices. METHODS: Forty participants were recruited for the current study (Study 1: 20 participants with the HMD device; Study 2: 20 participants with the flat monitor). They navigated a virtual room as a first-person viewer and used environmental landmarks to remember their spatial position and orientation. The main dependent measures were working memory error, reference memory error, detection time, travel distance, and participant’s head movements. To validate the program, participants also conducted neuropsychological assessments and self-reported measures. RESULTS: The results for HMD-RAM tasks were consistent with the results of previous research conducted on animals, and the HMD elicited a higher sense of presence, immersion, and simulator sickness than the flat monitor. According to post-experiment questions on navigation strategy, creating landmarks was important when people were discovering locations in their environment, and an HMD was beneficial for better navigation strategy. CONCLUSION: These results suggest that the HMD-RAM is valuable for estimating spatial learning and memory in humans and may be a useful tool for early diagnosis of deficits in spatial learning and memory, including amnestic mild cognitive impairment and Alzheimer’s disease.

BACKGROUND/OBJECTIVES: This study examined the socio-demographic and dietary characteristics of the elderly in Seoul according to their food insecurity status and analyzed the characteristics associated with food insecurity. SUBJECTS/METHODS: The data from 513 elderly individuals aged 65 or older were analyzed using the raw data from the Seoul Food Survey 2023. The subjects were classified into food-secure or food-insecure groups. The socio-demographic and dietary characteristics of each group were analyzed. Logistic regression analysis was conducted to identify the characteristics associated with food insecurity among the elderly in Seoul. RESULTS: The proportion of the food-insecure group was 56.9% among the total elderly in Seoul. The main reasons for experiencing food insecurity were environmental (38.0%), followed by physical (37.5%) and financial (24.5%). The food-insecure group had a higher frequency of skipping breakfast and eating alone than the food-secure group while having lower dietary literacy and food environment satisfaction. Logistic regression analysis showed that the elderly living alone were approximately four times (odds ratio [OR], 3.59; 95% confidence interval [CI], 1.52–8.51) more likely to suffer food insecurity than those living with others. Higher digital food literacy (OR, 0.63; 95% CI, 0.41–0.97) and food environment satisfaction (OR, 0.38; 95% CI, 0.20–0.74) were associated with a lower likelihood of food insecurity. CONCLUSION These results suggest that policies aimed at improving food security for the elderly in Seoul should prioritize those living alone. Educational programs designed to enhance the ability to purchase online food, use self-service kiosks in restaurants, and use food delivery apps would effectively decrease food insecurity among the elderly in Seoul.Furthermore, policies aimed at improving the food environment may also help reduce food insecurity among this population.

Purpose: This study aimed to analyze nationwide trends and regional disparities in inguinal hernia surgeries in South Korea between 2016 and 2022. Additionally, we aimed to evaluate changes in surgery frequency, including urban concentration and the introduction of robotic surgery. Methods: This retrospective review used nationwide data on inguinal hernia surgeries from the Health Insurance Review and Assessment Service database. Results: From 2016 to 2022, 254,367 inguinal hernia surgeries were performed in South Korea, with males accounting for 88.9% of cases. The annual number of surgeries fluctuated, particularly in 2020, owing to the coronavirus disease 2019 pandemic. Medical costs increased from $1,218.4 to $1,970 on average, whereas patient copayments rose from $180.2 to $293.3. Robotic inguinal hernia surgeries, introduced in 2019, increased to 226 cases in 2022. Pediatric surgeries steadily declined, whereas adult surgeries remained stable, with a slight increase in 2022. The average hospital stay did not change significantly but varied between pediatric and adult patients. Regional disparities were notable, especially in pediatric surgery rates between metropolitan areas, such as Seoul and the surrounding provinces. Conclusion This study highlights stable overall surgery rates, a decline in pediatric cases, and an increase in robotic inguinal hernia surgeries. The persistent concentration of healthcare services in metropolitan areas suggests a need for policy interventions to address regional disparities and ensure equitable healthcare access. The findings underscore the importance of ongoing efforts to improve healthcare distribution and the need for long-term strategies to address changing surgical trends.
