Objectives: This study validated the Vietnamese version of the Disaster Adaptation and Resilience Scale (DARS) for use in vulnerable communities in Vietnam. Methods: This was a cross-sectional study involving 595 adults from 2 identified communities. The original DARS assessment tool was translated, and the validity and reliability of the Vietnamese version of DARS (V-DARS) were assessed. The internal consistency of the overall scale and its subscales was evaluated using Cronbach's alpha and McDonald's omega reliability coefficients. Confirmatory factor analysis (CFA) was employed to evaluate its construct validity, building upon the factor structure identified in exploratory factor analysis (EFA). Construct validity was assessed based on convergent and discriminant validity. Results: Following the established criteria for EFA, 8 items were removed, resulting in a refined V-DARS structure comprising 35 items distributed across 5 distinct factors. Both alpha and omega reliability coefficients indicated strong internal consistency for the overall scale (α=0.963, ω=0.963) and for each of the 5 sub-scales (all>0.80). The CFA model also retained the 5-factor structure with 35 items. The model fit indices showed acceptable values (RMSEA: 0.072; CFI: 0.912; TLI: 0.904; chi-square test: <0.01). Additionally, the convergent and discriminant validity of the V-DARS were deemed appropriate and satisfactory for explaining the measurement structure. Conclusions: Our findings suggest that the V-DARS is a valid and reliable scale for use within vulnerable communities in Vietnam to assess adaptive responses to natural disasters. It may also be considered for use in other populations.

Purpose: This study aimed to investigate the current status of effective folic acid intake and the level of folic acid knowledge of Chinese pregnant women and to analyze the relationship between effective folic acid intake and folic acid knowledge. Methods: From November 2021 to May 2022, 140 pregnant women at Yantai Yuhuangding Hospital in the Chinese province of Shandong, answered questions about their general characteristics, folic acid intake, and folic acid knowledge. The data were analyzed using the t-test, chi-square test, and logistic regression analysis, and were presented with frequency with percentage or mean±standard deviation. Results: Only 16.4% of the pregnant women (n=23) took folic acid effectively, using the following four criteria. Of all pregnant women who took folic acid, 72.2% took folic acid starting 1 month before pregnancy, 70.8% took folic acid up to 3 months after pregnancy, 36.8% took 400 ㎍ every time, and 78.6% took folic acid more than 24 days every month. The score for folic acid knowledge was relatively high (5.61±2.18 on a scale of 0-9). A higher folic acid knowledge score correlated with more effective folic acid intake (t=4.10, p<.001). Conclusions: Our study shows that the current recommendations to prevent neural tube defects through effective folic acid intake supplementation are not being fully implemented in China. Furthermore, folic acid knowledge was positively correlated with the effectiveness of its intake. Future education related to effective folic acid intake should emphasize the four methods of effective folic acid intake, especially regarding the recommended dose of 400 ㎍ every time.

Objectives: This study investigated the association between eating habits and the utilization of dietary supplements (DSs) according to food-related lifestyle (FRL) among Korean adults. Methods: This study included a total of 300 participants (150 men and 150 women) in their 20s to 60s living in Seoul and Gyeonggi Province. We identified two groups by factor and cluster analysis: an 'active pursuit' group and a 'passive pursuit' group. Differences in eating habits and DS utilization between the two groups were analyzed by chi-square test and t-test. Logistic regression analysis was used to analyze the effect of variables on DS consumption according to FRL. Results: There were significant differences between the two groups in terms of age, alcohol drinking frequency, total dietary score, change in DS consumption after coronavirus disease 2019, and current DS consumption (P < 0.05). The proportion who perceived many health benefits of DSs was higher in the 'active pursuit' group than in the 'passive pursuit' group (P = 0.003). The most commonly consumed type of DSs was multivitamins & minerals for the 'active pursuit' group, and omega-3 fatty acids for the 'passive pursuit' group. The 'an active pursuit' group consumed DSs 2.93 times more (95% confidence interval [CI]: 1.44-5.97) compared to the 'passive pursuit' group, after adjusting for confounders. In the 'active pursuit' group, the health pursuit (odds ratio [OR] = 6.54, 95% CI: 1.44-29.61) and rational consumption pursuit factors (OR = 0.26, 95% CI: 0.08-0.83) were associated with DS consumption, whereas only the health pursuit factor had a significant association (OR = 5.37, 95% CI: 2.08-13.88) within the 'passive pursuit' group. However, total dietary score and DSs consumption did not show a relationship. Conclusions: By understanding the consumption characteristics of DSs according to FRL, this can serve as basic data necessary for promoting health through the utilization of DSs and healthy behaviors.

Purpose: This study investigated the association between dietary quality and the prevalence of periodontitis in older Korean adults (≥60 years of age) using data from the seventh Korea National Health and Nutrition Examination Survey (KNHANES VII, 2016-2018). Methods: Among the 16,489 KNHANES participants from 2016-2018, those aged ≥60 years were selected as the eligible population. After applying our exclusion criteria, 3,527 participants were included in the final study population. Periodontal status was measured using the Community Periodontal Index (CPI). To determine the association between dietary quality and the prevalence of periodontitis, analysis of variance, the chi-square (χ²) test, and logistic regression analysis were performed. Results: The population was divided into quartile groups and stratified by sex. The percentage of men and women with periodontitis was 54.34% and 42.74%, respectively. The quartile with higher Korean Healthy Eating Index scores had a lower percentage of people with periodontitis in both sexes. For men, only vegetable intake showed a significant difference between sub-groups with or without periodontitis, whereas, for women, the intake of fruits, milk, sweets, carbohydrates, and fats showed significant differences. There was a strong positive association between vegetable intake and periodontitis in men in the 3 models used in this study; model 3 had an adjusted odds ratio (aOR) of 1.367 (95% confidence interval [CI], 1.091-1.712). In women, a strong positive association with periodontitis was shown for sweets in all 3 models, with an aOR of 1.477 in model 3 (95% CI, 1.125-1.939). Conclusions: Dietary quality was inversely associated with the prevalence of periodontitis in Korean adults aged ≥60 years. Further comprehensive studies are needed to help establish nutrition and health policies for older adults in Korea.

Background: China carries a heavy burden of cervical cancer (CC) and substantial disparities exist across regions within the country. In order to reduce regional disparities in CC, the government of China launched the National Cervical Cancer Screening Program in Rural Areas (NCCSPRA) in 2009. Critical to the success of the program are the health care workers who play a pivotal role in preventing and managing CC by encouraging and motivating women to use screening services and by providing identification and treatment services. This study aimed to assess cervical cancer knowledge among these health care workers at the county level in maternal and child health (MCH) hospitals across different socio-economic regions of China. Materials and Methods: A cross-sectional survey was conducted and self-administered questionnaires were sent to all health care workers (a total of 66) providing cervical cancer screening services in 6 county level MCH hospitals in Liaoning, Hubei and Shaanxi provinces, representing eastern, central and western regions of China; 64 (97.0%, 64/66) of the workers responded. ANOVA and Chi-square test were used to compare the knowledge rate and scores in subgroups. Results: The knowledge level of the respondents was generally low. The overall combined knowledge rate was 46.9%. The knowledge rates for risk factors, prevention, clinical symptoms, screening and diagnostic tests and understanding of positive results were 31.3%, 37.5%, 18.1%, 56.3% and 84.4%, respectively. Statistically significant differences in scores or rates of CC knowledge were seen across the different regions. The total and sectional scores in the less developed regions were statistically significantly lower than in the other regions. Conclusions: The majority of the health care workers who provide CC screening service in NCCSPRA at county level MCH hospitals do not have adequately equipped with knowledge about CC. Given the importance of knowledge to the program's success in reducing CC burden in rural women in China, efforts are needed to improve the knowledge of health care workers, especially in less developed regions.

본 연구는 반복 수평 하중을 받는 외부 보-기둥 접합부에서 작은 헤드를 사용한 headed bar의 사용성을 검증하기 위해 $90^{\circ}$ 표준갈고리로 정착한 실험체와 headed bar로 정착한 접합부 실험체를 제작하여 각각의 실험 결과를 비교하였다. 또한, headed bar 정착 성능에 영향을 주는 헤드 단면적, 단조 및 반복 가력 여부, 헤드와 보강근의 용접 여부등의 headed bar 인발 성능에 관한 영향을 구명하기 위한 인발실험을 병행하였다. 인발실험의 결과, headed bar의 인발강도는 헤드 면적 증가에 따라 증가하였고, 헤드와 보강근의 용접 유무, 가력 조건 (단조하중 및 반복하중)은 실험 결과에 큰 영향을 미치지 않는 것으로 나타났다. 외부 보-기둥 접합부 실험의 결과, $90^{\circ}$ 표준갈고리로 정착한 실험체와 headed bar로 정착한 실험체가 초기 균열, 균열의 발생 등 모두 거의 비슷한 양상이었으나, 최종 파괴 시에는 headed bar로 정착된 실험체가 $90^{\circ}$ 표준갈고리로 정착된 실험체에 비해 최대 강도 도달 이후 연성 거동, 연성비 및 변형 성능, 에너지소산 면적 등에서 우수한 거동을 보여주었다. 따라서 ACI 352 위원회의 설계지침을 따라서 제작된 접합부 상세와 동일한 조건으로 표준갈고리 대신 상대적으로 작은 headed bar를 사용할 수 있을 것으로 판단된다.

Quantile regression is an efficient method for predicting and estimating the relationship between explanatory variables and percentile points of the response distribution, particularly for extreme percentiles of the distribution. To study the relationship between urbanization and cancer morbidity, we here applied quantile regression. This cross-sectional study was conducted for 9 cancers in 345 cities in 2007 in Iran. Data were obtained from the Ministry of Health and Medical Education and the relationship between urbanization and cancer morbidity was investigated using quantile regression and least square regression. Fitting models were compared using AIC criteria. R (3.0.1) software and the Quantreg package were used for statistical analysis. With the quantile regression model all percentiles for breast, colorectal, prostate, lung and pancreas cancers demonstrated increasing incidence rate with urbanization. The maximum increase for breast cancer was in the 90th percentile (${\beta}$=0.13, p-value<0.001), for colorectal cancer was in the 75th percentile (${\beta}$=0.048, p-value<0.001), for prostate cancer the 95th percentile (${\beta}$=0.55, p-value<0.001), for lung cancer was in 95th percentile (${\beta}$=0.52, p-value=0.006), for pancreas cancer was in 10th percentile (${\beta}$=0.011, p-value<0.001). For gastric, esophageal and skin cancers, with increasing urbanization, the incidence rate was decreased. The maximum decrease for gastric cancer was in the 90th percentile(${\beta}$=0.003, p-value<0.001), for esophageal cancer the 95th (${\beta}$=0.04, p-value=0.4) and for skin cancer also the 95th (${\beta}$=0.145, p-value=0.071). The AIC showed that for upper percentiles, the fitting of quantile regression was better than least square regression. According to the results of this study, the significant impact of urbanization on cancer morbidity requirs more effort and planning by policymakers and administrators in order to reduce risk factors such as pollution in urban areas and ensure proper nutrition recommendations are made.

이 연구에서 격막이 설치된 각형 CFT 기둥의 장기거동에 관한 실험과 해석을 수행하였으며, 이를 통해 각형 CFT 기둥의 장기거동에 미치는 격막의 영향을 파악해 보고자 하였다. 격막의 크기에 따라 두 가지, 기둥 길이에 따라 세 가지 변수를 두어 총 6가지의 변수에 대한 실험과 각 실험체에 대한 3차원 유한요소 해석을 수행하였다. 강관과 콘크리트의 계면 거동을 고려한 유한요소 해석은 격막이 설치된 CFT 기둥의 실제 거동을 정확히 모사하였으며, 이를 통해 유한요소 모델링의 정확성이 검증되었다. 실험과 해석 결과로부터 다음과 같은 결론을 얻었다. 격막에 의한 기둥 단부의 구속 효과는 기둥의 길이에 상관없이 CFT 기둥의 단부에서 기둥의 폭만큼 내려간 위치까지이며, 이외의 부분에서 격막 또는 강관에 의한 구속 효과는 나타나지 않았다. 또한 내부 콘크리트 면적의 1/2 이상을 가압할 수 있는 격막이 설치된 각형 CFT 기둥의 장기변형에 의한 축소량은 강관과 콘크리트의 전체 면적을 동시에 가압한 경우의 축소량과 동일하다.
