This study examines fourth graders engaged in three concrete activities involving sampling from finite populations. The first included a survey of popular foods for school meals. The second had them take samples from a box containing white and black marbles to predict how many white and black marbles were in the box. The final activity required them to predict how many times the Korean letter '가' would appear in a Korean story book. The results show that the participants can experience and notice different ideas related to samples and sampling in different activities. In the first activity, they acknowledged that samples are useful for obtaining the information about populations. A population survey is difficult and is not overly useful. In the second activity, they recognized that samples cannot be identical to their population but that the information from a group of samples is similar to the information of the population. In the last activity, they devised some ideas about random sampling even though the ideas were immature.

Background: Major questions remain regarding the agestratified trends of allergic diseases and asthma in Korea. Purpose: To identify the estimated recent prevalence and 10-year trends in asthma, allergic rhinitis, and atopic dermatitis among the Korean population from 2008 to 2017. Methods: This nationwide cross-sectional survey (Korean National Health and Nutrition Examination Survey) over 10 years (2008-2017) examined representative samples of the Korean population (n=85,006) including 2,131 infants, 4,352 preschool children, 12,919 school-age children, 44,200 adults, and 21,404 elderly adults. Results: In the 2016 to 2017 population, the estimated prevalence of asthma was 0.9% in infants, 2.3% in preschool children, 4.1% in school-age children, 2.3% in adults, and 4.1% in the elderly. The estimated prevalence of allergic rhinitis was 9.0%, 20.2%, 27.6%, 17.1%, and 6.9%, respectively. The estimated prevalence of atopic dermatitis was 5.9%, 11.3%, 14.6%, 3.9%, and 1.6%, respectively. Ten-year trends revealed a significant decrease in asthma prevalence in infants, preschool children, and the elderly. and in atopic dermatitis prevalence in infants and preschool children (P<0.05 for all trends). Furthermore, 10-year trends demonstrated a significant increase in allergic rhinitis prevalence in school-age children, adults, and the elderly, and in atopic dermatitis prevalence in school-age children and the elderly (P<0.05 for all trends). Conclusion: These results improve our understanding of the age-stratified epidemiology of allergic diseases in Korea and suggest the need for the development of tailored and precise strategies to prevent allergic diseases in different age groups.

Summary measures of population health or SMPH is an index which can describe morbidity as well as mortality. Summary measures of population health can be divided into health-adjusted life years which is a life expectancy measure and disability-adjusted life years which represents the gap between the ideal health status and the current health status. This study aims at estimating health-adjusted life expectancy(HALE) which is a measure of health-adjusted life years, by calculating life expectancy adjusted by health status using EQ-5D. The mortality data was obtained from the life table of 2005 which was published by the National Statistical Office and the health status by sex and age was obtained from the EQ-5D scores using the third National Health and Nutrition and Examination Survey in 2005. With these mortality and morbidity data, health-adjusted life expectancy was calculated using Sullivan's method. The study results showed that the health-adjusted life expectancy of males and females was 67.49 and 69.61, respectively, while the life expectancy of males and females was 75.14 and 81.89. In other words, Korean males and females lose 7.65 and 12.28, respectively, from the decrease of quality of life due to diseases and/or injuries. These results can further be interpreted that males lose 10.2% of their life expectancy and females 15.0%. This study suggests that it may be possible to monitor population's health-adjusted life expectancy by continuing to include health-related quality of life measures such as EQ-5D in national health surveys like the National Health and Nutrition and Examination Survey.

A dramatic decline in the abundance of the scaled quail (Callipepla squamata) has been observed across most of its geographic range. In order to evaluate the influence of land cover patterns and their changes on scaled quail abundance, we examined landscape patterns and their changes from the 1970s to the1990s in two large ecoregions with contrasting population trends: (1) the Rolling Plains ecoregion with a significantly decreased scaled quail population and (2) the South Texas Plains ecoregion with a relatively stable scaled quail population. The National Land Cover Database (NLCD) and the U.S. Geological Survey's (USGS) Land Use/Land Cover data were used to quantify landscape patterns and their changes based on 80 randomly located $20{\times}20km^2$ windows in each of the ecoregions. We found that landscapes in the Rolling Plains and the South Texas Plains were considerably different in composition and spatial characteristics related to scaled quail habitats. The landscapes in the South Texas Plains had significantly more shrubland and less grassland-herbaceous rangeland; and except for shrublands, they were more fragmented, with greater interspersion among land cover classes. Correlation analysis between the landscape metrics and the quail-abundance-survey data showed that shrublands appeared to be more important for scaled quail in the South Texas Plains, while grassland-herbaceous rangelands and pasture-croplands were essential to scaled quail habitats in the Rolling Plains. The decrease in the amount of grassland-herbaceous rangeland and spatial aggregation of pasture-croplands has likely contributed to the population decline of scaled quails in the Rolling Plains ecoregion.

Background & Objectives: The most northern and northwestern regions of Iran are at a high risk for gastric cancer. The aim of this study was to assess the general population's awareness about risk factors, symptoms and signs, preventive methods and management of gastric carcinoma in a high prevalence city in the North of Iran. Methods: A cross-sectional population-based telephone survey which was conducted on 3,457 residents of Rasht, the capital city of Guilan Province, to assess their awareness regarding gastric carcinoma. The questionnaires contained demographic data and statements on respondents' knowledge about risk factors, symptoms and signs, prevention and management of gastric cancer which were filled by general practitioners after asking the subjects. Data were analyzed in SPSS14. P<0.05 was considered significant. Results: The mean knowledge score of the respondents was $5.05{\pm}1.37$ regarding risk factors of gastric carcinoma, $4.39{\pm}1.99$ regarding symptoms and signs, $6.0{\pm}1.22$ regarding preventive strategies, and $1.6{\pm}1.16$ regarding management. Totally the mean knowledge level of the respondents toward gastric carcinoma would be $17.1{\pm}3.97$ from the maximum grade of 29. The age group of 45-55 y/o, bachelor degree and higher, physicians and nurses, those who had cancer history in friends or had the history of gastrointestinal diseases showed significantly higher knowledge scores (P=0.001). Conclusion: There is a general lack of awareness of cancer risk factors, symptoms and signs, methods of prevention, and importance of early diagnosis and treatment. Educational programs should be developed to promote adherence to recommended screening guidelines.

According to data from the national office of Statistics Korea and Ministry of Health and Welfare, as the elderly population increases, the dementia elderly population continues to increase and its future population growth rate is expected to be even faster. In particular, the Dementia Management Act has been in effect since February 2012, and active efforts has been made for a policy for the dementia management. The purpose of this study is to establish standards on building plans based on the appropriate scale and spatial configuration on facilities planning for the elderly with dementia. Specifically, the basic data were collected with a request for a total of 103 points on the basis of a database of group homes in the survey managed by the Japan Association of Group Homes. Specific information of the research includes the management body of facilities operation, scale of the facilities, number of units and configuration of personal living space, and the collected survey data and drawings were statistically proceed and analyzed using the SPSS WIN 20.0. analysis results are summarized as follows. first, most of the group homes come to the small size of the 1-2 story home ; the approximate number of units is one or two per home, and each unit consists of nine rooms. second, a number of group homes with the building area of $300m^2$ have the U-shaped arrangement which is advantageous in the extension and facilities maintenance. In conclusion, this study is to be the fundamental data for judgments that can be used to establish standards for the facilities for the dementia elderly whose population continues to increase. In addition, further study is necessary to establish suitable design conditions of our country.

Objectives: Chronic anaemia is a significant health concern, particularly among women of childbearing age. Factors such as menstrual blood loss, childbirth, inadequate nutrition, closely spaced pregnancies, and recurrent gastrointestinal bleeding increase the risk of anaemia. This study investigated whether current contraceptive methods are associated with anaemia in Indian women of reproductive age. Methods: Cross-sectional data from the fifth round of the National Family Health Survey, conducted in 2019-2021, were used for this investigation. We included only non-pregnant and non-amenorrhoeic women in our analysis, resulting in a final analytical sample of 673 094 women aged 15-49. Bivariate cross-tabulations and multivariable logistic regression were employed to analyse the data. Results: The prevalence of anaemia was 57%, and the adjusted regression models found no significant association between the use of any contraceptive methods and women's haemoglobin status. Women using traditional contraceptive methods had 1.08 (95% confidence interval, 1.05 to 1.11) times higher odds of having anaemia. Among the modern methods, other than injectables, all other methods-such as an intrauterine device, barrier use, and sterilisation-were associated with higher odds of anaemia compared to women who used contraceptive pills. Conclusions: This study explored the relationship between modern contraceptives and haemoglobin levels in India, revealing that injectables were associated with a notable reduction in the odds of anaemia, whereas traditional contraceptives and other modern methods exhibited positive associations with anaemia. These findings prompt policymakers to focus on anaemia reduction and safe contraceptives. More research is needed to inform decisions, given the scant literature.

This paper deals with the use of the separate ratio estimator in the survey of cultivated land area. As a kind of repeated survey conducted every year, this survey estimates the total cultivated land area by using the separate ratio estimator. When using the separate ratio estimation in the survey, we may face with some practical problems such as (i) changing population size over time, (ii) auxiliary variables taken zero values in some strata and (iii) changing stratification criteria due to sample redesign. In this paper, after investigating practical problems occurred in the survey we presented some adjusted separate ratio estimators to tackle such problems.

An empirical Bayesian approach is discussed for estimation of characteristics from the two-way balanced rotation sampling design which includes U.S. Current Population Survey and Canadian Labor Force Survey as special cases. An empirical Bayesian estimator is derived for monthly effect under presence of two types of biases and correlations It is shown that the marginal distribution of observation provides more general correlation structure than that frequentist has assumed. Consistent estimators are derived for hyper-parameters in Normal priors.
