Recently the Ministry of Health and Welfare, Republic of Korea, announced the “Dietary Guidelines for Korean Adults (DGKA)”, which includes ten Dietary Goals, six Dietary Guidelines, and twenty-three Action Guidelines. DGKA are developed as the revision of the 2003 Dietary Guidelines for Koreans, targeting adult population. Dietary Guidelines are developed for general purpose as well as for different age groups. They are revised periodically to accommodate changes in diet and health problems of the population. The process of developing new DGKA can be summarized as 1) selection of focus areas, 2) analysis and review of available data for each area selected, and 3) derivation of guidelines based on the analyzed data, and 4) finalizing the guidelines after open discussions among the experts and general public. Five focus areas were selected by examining the Nutrition Goals of the Health Plan 2010 of Korea, soliciting proposals from the experts in the related fields, and reviewing existing and international guidelines. Five areas selected were 1) adequate intake of nutrients and foods, 2) balance of energy intake and physical activities, 3) alcohol intake, 4) food security and nutrition service, and 5) food safety. Adequacy of nutrient and food intakes of the Korean adult population was assessed using 2005 Korea National Health and Nutrition Examination Survey (KNHANES) data. Newly developed Dietary Reference Intakes for Koreans were used as reference values to assess the prevalence of inadequacies and excesses in nutrient intakes. Energy balance was examined with energy intake of 2005 KNHANES survey and results of physical activity questionnaire in the survey. Alcohol intake was also examined using 2005 KNHANES results of dietary intakes as well as the results of questionnaire survey on alcohol intakes. Food security, nutrition services, and food safety were analyzed using various government data and published results on the issues. Ten Dietary Goals and six Dietary Guidelines were developed after data analysis and were subjected to reviews of experts and general public. The final DGKA are: 1) Eat a variety of foods from each food group, 2) Increase physical activity and maintain healthy weight, 3) Eat proper amount of clean foods, 4) Avoid salty foods and try to eat foods with bland taste, 5) Avoid foods with high fat contents and deep-fried foods, and 6) When you drink alcohol, limit the amount. Twenty-three action guidelines are developed in order to achieve these guidelines in actual diet and life among the population. The government is disseminating the guidelines with “337” slogan and emblem. “337” indicates everyone should practice “3” guidelines of promoting good eating practice, “3” guidelines to limit or decrease in your diet, and you should practice them for “7” days a week. The guidelines will be useful in promoting healthy food habits and good nutritional status which will result in decrease nutrition related health problems in Korea.

The marine ecosystem survey investigates and analyzes multi-parameters at various times from various sites. Therefore, it is very difficult to analyze the complex ecological data of multi-items effectively, and it is more difficult to identify the current status and diagnose the problems of ecosystem through data analysis. Therefore, this paper aims to provide an example of interpretation of complex ecological data through analysis of distribution characteristics and outliers of ecological survey data. The main contents of the study are to elucidate the background levels of coastal ecosystem parameters considering the distribution characteristics of data, and to establish ecosystem monitoring indicators and an adaptive management system for the coastal waters in Korean Peninsula. The data used in this paper are based on the coastal ecosystem survey of the National Marine Ecosystem Monitoring Program conducted by the Ministry of Oceans and Fisheries (MOF) and the Korea Marine Environment Management Corporation (KOEM), and the major citations are from year 2015 to 2017. This article is a preliminary study to establish the above processes and the final result will be derived in 2020 when the coastal ecosystem survey is completed three times along the Korean coast.

This study was designed to examine the depressive symptoms of individuals who became visually impaired and identify factors associated with the symptom. For the analysis, data from the Korean National Survey of Individuals with Disability 2014 was used. Adults between the ages of 20 and 60 years who became visually impaired after the first year of birth were included with a total of 235 individuals in the final sample. To identify the determinants of their depressive symptoms, a multivariate logistic regression analysis was conducted. The results showed that about twenty percent of the respondents reported having depressive symptoms in the past year. Among the sociodemographic factors, age, gender, and marital status were identified as significant predictors, while smoking status, stress level, and self-reported health status were identified as important health-related predictors. Among the disability-related factors, the length of disability and activities of daily living level were found to be significantly associated with the likelihood of experiencing the symptom. The results indicate the need for practitioners working with visually impaired populations to be better aware of the risks of depression and develop a wide array of preventive measures and techniques to work with individuals suffering from depression.

This study was conducted to evaluate the association between periodontal disease and diabetes mellitus. The final analysis population of this study was composed of 4,830 adults with diabetes mellitus or periodontal disease and aged 19 years or older, based on the third-edition data of the 4th Korea National Health and Nutrition Examination Survey (KNHANES) (in 2009). Diabetic status and potential confounders were used in questionnaire materials and physical examination materials, and the presence of periodontal disease was used in the materials for oral health examination by a dentist. For diabetic status, fasting plasma glucose (FPG) levels <100 mg/dl were subcategorized into normal group and FPG levels ${\geq}100mg/dl$ into impaired fasting glucose group; glycosylated hemoglobin (HbA1c) levels <7% into normal group and HbA1c ${\geq}7%$ into diabetes group, on the basis of the American Diabetes Association. According to the 2009 Korea Health Statistics, the case where the pocket depth is 3 mm or more was defined as periodontal disease. The association between the two diseases was evaluated through $x^2$-test and logistic regression analysis using R-commander 2.14. In impaired fasting glucose group, community periodontal index (CPI) groups 3 to 4 had higher risks for periodontal disease 1.23 times (95% confidence interval, 1.07~1.42) than those of CPI groups CPI 0~2, even after adjustment for several confounders. In addition, periodontal disease and diabetes mellitus showed statistically significant differences depending on age, sex, income level, educational background, smoking status, alcohol consumption, and snack intake. The analyses of the third-edition data of the 4th KNHANES showed that there was a statistically significant association between periodontal disease and diabetes mellitus as examined by means of CPI in this study.

This study aims to design a Severity-Adjusted LOS(Length of Stay) Model in order to efficiently manage LOS of AMI(Acute Myocardial Infarction) patients. We designed a Severity-Adjusted LOS Model with using data-mining methods(multiple regression analysis, decision trees, and neural network) which covered 6,074 AMI patients who showed the diagnosis of I21 from 2004-2009 Korean National Hospital Discharge in-depth Injury Survey. A decision tree model was chosen for the final model that produced superior results. This study discovered that the execution of CABG, status at discharge(alive or dead), comorbidity index, etc. were major factors affecting a Sevirity-Adjustment of LOS of AMI patients. The difference between real LOS and adjusted LOS resulted from hospital location and bed size. The efficient management of LOS of AMI patients requires that we need to perform various activities after identifying differentiating factors. These factors can be specified by applying each hospital's data into this newly designed Severity-Adjusted LOS Model.

This descriptive research investigates the knowledge of and attitude toward HIV/AIDS among individuals in their 20s to 40s. This study also analyzes the results of the 2011 and 2013 community health surveys to identify the factors influencing their knowledge and attitude. The study subjects were 20 to 49 years old, and the final analysis included 182,315 subjects. The collected data were analyzed through t-tests, ANOVA, correlational analysis, and multiple regression analysis. The survey results showed a high level of knowledge of HIV/AIDS, with 69.4% correct answers. Most individuals lacked knowledge regarding routes of infection, and those in their 20s had the lowest percentage of correct answers. As for attitude toward HIV/AIDS, 44.3% showed a negative attitude. The scores for knowledge and attitude toward HIV/AIDS were higher among males, unmarried individuals, individuals with a higher income, individuals with a higher level of education, individuals working in agriculture, forestry, or fishery, managers, professions that were not homemakers/unemployed, and professional soldiers. A positive correlation (r=0.27, p<0.001) was observed between knowledge and attitude. The factors influencing AIDS knowledge and attitude were gender, marital status, income level, occupation, and education level. This study confirmed that there is a difference by age group. As such, educational programs customized by age and other characteristics are expected to be more effective in enhancing knowledge and in developing a more positive attitude towards HIV/AIDS.

Purpose : The objective of this study was to determine the major factors influencing the onset of diabetes and prediabetes and for collection of the basic data required to reduce the prevalence of diabetes and plan for administration of an effective health care system. By classifying the level of blood sugar management according to three categories: normal, prediabetes, and diabetes diagnosis, and determining the causes of diabetes in consideration of various variables, we will conduct an analysis of the main factors to be addressed for effective management of blood sugar and for preparation of basic data for use in early management. Methods : In this study, an analysis of raw data from the 8th National Health and Nutrition Examination Survey collected over a period of three years from 2019 to 2021, including 8,110 subjects in 2019, 7,359 subjects in 2020, and 7,090 subjects in 2021 was performed. A total of 22,559 subjects were aged 19 years or older, and 15,821 subjects were classified as subjects for inclusion in the final analysis. In the analysis, categorical variables were tested for difference, analysis of continuous variables using regression was performed, and analysis of influencing factors was performed using multinomial logistic analysis. Result : Significant factors related to the onset of diabetes and prediabetes included age (p<.001), marital status (p<.001), occupation (p<.001), hypertension (p<.001), dyslipidemia (p<.001), cardiovascular disease (p=.008), alcohol (p=.030) smoking (p=.005), systolic blood pressure (p<.001), diastolic blood pressure (p<.001), body mass index (p<.001) and waist circumference (p=.037), blood triglycerides (p<.001), and blood cholesterol (p<.001). Conclusion : Diabetes, a complex disease affected by a variety of diseases, requires active management from the prediabetes stage, and providing an appropriate level of medical information and services to elderly individuals without family support is considered a long-term health care system requirement in Korean society where the demographic structure is changing. In particular, determining the causes of prediabetes and development of a preventive approach to administering the health care system will be important for efficient management of diabetic patients.

Purpose: This study was conducted to identify unmet healthcare needs among man and woman one-person households and to explore related factors by gender. Methods: Data were drawn from the 2017 Korea National Health and Nutrition Examination Survey. The final sample consisted of 820 one-person households. The statistical analysis, conducted in SPSS version 20.1, included complex sampling analysis; descriptive statistics, the chi-square test, and logistic regression. Results: The demographic and socioeconomic characteristics of women in one-person households were significantly different from those of men in one-person households. Women in single-person households were mainly in their 70s or older and married, and they tended to have a low education level, low income, and no formal occupation. Unmet healthcare needs were experienced by 17.3% of women in one-person households and 13.5% of men in one-person households, which was not a statistically significant difference (χ²=2.17, p=.139). Factors related to unmet healthcare needs were subjective health status and unmet dental care needs in single-person-household men. By contrast, having experienced impairment within the past year, stress, and unmet dental care needs were factors related to unmet healthcare needs in single-person-household women. Conclusion: As one-person households become increasingly common, more attention needs to be paid to them and our understanding of them needs to be improved. Women in one-person households, in particular, are especially vulnerable, as they experience more unmet healthcare needs.
