Objectives: Self-rated health is a measure of perceived health widely used in epidemiological studies. Our study investigated the determinants of poor self-rated health in middle-aged Korean adults with diabetes. Methods: A cross-sectional study was conducted based on the Health Examinees Study. A total of 9759 adults aged 40 to 69 years who reported having physician-diagnosed diabetes were analyzed with regard to a range of health determinants, including sociodemographic, lifestyle, psychosocial, and physical variables, in association with self-rated health status using multivariate logistic regression models. A p-value <0.05 was considered to indicate statistical significance. Results: We found that negative psychosocial conditions, including frequent stress events and severe distress according to the psychosocial well-being index, were most strongly associated with poor self-rated health (odds ratio $[OR]_{\text{Frequent stress events}}$, 5.40; 95% confidence interval [CI], 4.63 to 6.29; $OR_{\text{Severe distress}}$, 11.08; 95% CI, 8.77 to 14.00). Moreover, younger age and being underweight or obese were shown to be associated with poor self-rated health. Physical factors relating to participants' medical history of diabetes, such as a younger age at diagnosis, a longer duration of diabetes, insulin therapy, hemoglobin A1c levels of 6.5% or more, and comorbidities, were other correlates of poor reported health. Conclusions: Our findings suggest that, in addition to medical variables, unfavorable socioeconomic factors, and adverse lifestyle behaviors, younger age, being underweight or obese, and psychosocial stress could be distinc factors in predicting negative perceived health status in Korean adults with diabetes.

Purpose : Obesity indices are major predictive markers for coronary artery stenosis, but there are few studies about the relationship between obesity indices and coronary artery stenosis in the Korean population. Therefore, we analyzed the association between obesity indices and coronary artery stenosis among health-screen examinees. Methods : This study included 99 males and females who visited a health-examination center. The obesity indices included body mass index (BMI), waist circumference (WC), visceral adipose tissue (VAT), visceral adipose tissue/subcutaneous adipose tissue ratio (V/S ratio). All subjects had their degree of coronary artery stenosis measured using coronary computed tomography angiography (CCTA). A multiple logistic regression test was conducted to analyze the association between obesity indices and coronary artery stenosis. Results : This study was taken by multiple logistic regression test adjusted by age, sex, smoking status, frequency of alcohol drinking/week and frequency of exercise/week. The adjusted odds ratio for the presence of coronary artery stenosis for subjects with abdominal obesity (abdominal obesity defined as a waist circumference ≥ 90 cm in males; ≥ 85 cm in females) was 6.263 (95 % confidence interval (CI) 1.974-19.869), for subjects with visceral obesity by visceral adipose tissue (visceral obesity defined as a visceral adipose tissue ≥ 100) was 11.430 (95 % CI 3.044-42.928). Conclusion : In this study of adults, WC and VAT were independent predictors of coronary artery stenosis. These results suggest that WC and VAT may be useful markers of coronary artery stenosis.

This study aimed to analyze the occurrence of colon polyps and also risk factors of colon polyps. Among health examination examinees, 508 people were included who underwent colonoscopy and abdominal ultrasonography at the same time. Physical measurements also performed such as height, weight, blood pressure, waist measurement and BMI. General characteristics including age, sex, smoking, drinking and exercise as a risk factors were checked. At the same time, we analyzed various blood tests and fasting blood sugar through blood-gathering. In the results, regarding risk factors of colon polyps, AST, ALT, TC, fatty liver, obesity and smoking were shown significantly high. As a dependent variable with colon polyps, the highest relation was fatty liver(3.4 times), and then T-C(2.3 times). Smoking factor showed 2.3 times higher relation than non-smokers.

The Judgement on a certain maritime accident accompany with punishment or recommendation to the examinee who was connected with that accident. It also gives quite a consequence to the Civil Trial relating with the maritime accident. In the Maritime Safety Tribunal System, the examinees can get assistance from Maritime Counselor. As it requires a lot of costs, it should be limited by economic condition of the examinees. In this Paper, with the consideration of the several kinds of Free Counsel System, Free Counsel System for Maritime Safety Tribunal was studied. The proposals are as follows; 1. To introduce the Mandatory Counselling and Court-designated Counselor System. The costs to be paid by government. 2. The same as above but the counselor to be designated among the staffs of the maritime organizations, then the costs to be paid by the organization which they belonged. 3. To establish Maritime Safety Tribunal Association which performs Monetary Assistance same as Korean Legal Aid Corporation.

The purpose of this study was to investigate the association of blood pressures, hematological and blood biochemical properties according to the degree of obesity based on differential combinations of BMI in health checkup examinees. Study subjects were 3,731 adults of 20 years and over (2,312 males, 1,419 females), not recognized as taking medicines for or having cardiovascular diseases, who underwent health package check-up at the Korea Association of Health Promotion, Daejeon Branch from Jan. 2007 to Dec. 2009. As a results, the mean values of SBP, DBP, TG, TC, LDL-C, ALT, AST, GGT, ALP were significantly increased with higher level of BMI, but the HDL-C was significantly decreased with higher level of BMI. On correlation of BMI with various factors, the BMI was positively correlated with SBP, DBP, TG, TC, LDL-C and GGT, while the HDL-C was negatively correlated. Based on the result of ordinal logistic regression analysis, the risk ratio to the abnormal level of SBP, DBP, TG, ALT and GGT were significantly increased as BMI increased.

To determine the status of infection caused by intestinal parasites among children and adolescents living in Legaspi city, the Philippines, we performed a small survey by fecal examination for helminth ova and protozoan cysts with formalin-ether concentration method. Of the 64 examinees, the infection rate was 78.1%. The infection rates of primary school children, preschool children and adolescents were 95.5%, 64.7% and 87.5%, respectively. The infection rate in urban areas was 56%, and 92.3% in rural areas. The infection rates were 51% with Trichuris trichiura, 40% with Ascaris lumbricoides, 23.4% with hookworm, 15.6% with Iodamoeba butschlii, 14.1% with Endolinax nana, 9.4% with Entamoeba coli and 7.8% with Giardia lamblia. There were 33 cases with multiple infection (51.6%). Mixed infection with more than 3 parasites was observed in 15 cases, all of them being children and adolescents living in rural areas. By this survey, it was conjectured that helminthic infection is prevalent among children and adolescents in Legaspi, Philippines.

This study was conducted to assess the distribution of coronary risk factors(CRF) and evaluate the risk profile of coronary heart disease by the clustering of the CRF in health checkup examinees. The study sample consists of 3,345 adults aged 30s-60s years(1,917 males, 1,428 females), not recognized as taking medicines for or having cardiovascular diseases, who underwent health package check-up at the health examination center of a university-affliated hospital in Daejon City. The proportion of subjects with 1, 2, 3, 4 and or more risk factors were 27.6%, 26.5%, 16.9% and 9.1%, respectively, therefore, the 80.0% of total subjects had at least one more risk factor. From these findings, this study concluded that the prevalence rates of CRF were relatively high. These data provide further evidence that the early intervention for coronary health prevention and promotion in general adult population is necessary at the population level.

Objectives: Self-reported disease history is often used in epidemiological studies. In this study, we acquired the hospital records of subjects who self-reported stroke or myocardial infarction (MI) and evaluated the validity of the participants' self-reported disease history. We also determined the level of agreement between specialists and non-specialists. Methods: Among the participants in the Health Examinees study, 1488 subjects self-reported stroke or MI during 2012-2017, and medical records were acquired for the 429 subjects (28.8%) who agreed to share their medical information. Each record was independently assigned to 2 medical doctors for review. The records were classified as 'definite,' 'possible,' or 'not' stroke or MI. If the doctors did not agree, a third doctor made the final decision. The positive predictive value (PPV) of self-reporting was calculated with the doctors' review as the gold standard. Kappa statistics were used to compare the results between general doctors and neurologists or cardiologists. Results: Medical records from 208 patients with self-reported stroke and 221 patients with self-reported MI were reviewed. The PPV of self-reported disease history was 51.4% for stroke and 32.6% for MI. If cases classified as 'possible' were counted as positive diagnoses, the PPV was 59.1% for stroke and 33.5% for MI. Kappa statistics showed moderate levels of agreement between specialists and nonspecialists for both stroke and MI. Conclusions: The validity of self-reported disease was lower than expected, especially in those who reported having been diagnosed with MI. Proper consideration is needed when using these self-reported data in further studies.

Purpose: The purpose of this study is to classify space types according to the operating system of health examination centers and compare and analyze their sizes. Methods: Seven examination centers under the K Medical Research Institute with the same operating system and similar examination types and functional spaces are the subject of the investigation. Research is conducted through field investigation, user surveys, and drawing analysis. Results: The operating method of the health examination center can be largely divided into the function dispersed type and the function central type. The function dispersed type was planned as a vertical type, and the function central type was planned as a horizontal type. In the case of the function dispersed type, since the examinees move vertically to use the endoscope center and special examination center, the efficiency of the vertical movement must be considered when planning the function dispersed type of facility. The function dispersed type plans to increase work and manpower efficiency by arranging the areas used at the start and end of the examination. Because the function central type horizontally arranges related functions by area, it should be planned in a structure that makes it easy for examinees to find their way. Implications: Through this study, it is judged that it is possible to suggest architectural planning considerations that vary depending on the operation system of the examination center.

Objectives: The association between long sleep duration and mortality is frequently attributed to the confounding influence of comorbidities. Nevertheless, past efforts to account for comorbidities have yielded inconsistent outcomes. The objective of this study was to evaluate this relationship using a large prospective cohort in Korea. Methods: The study included 114 205 participants from the Health Examinees Study, who were followed for a median of 9.1 years. A composite comorbidity score was developed to summarize the effects of 21 diseases. Using Cox proportional hazards regression, hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause, cancer, and cardiovascular mortality associated with sleep duration were estimated. These estimates were adjusted for socio-demographic factors, lifestyle factors, body mass index, and comorbidity score. Additionally, a stratified analysis by subgroups with and without comorbidities was conducted. Results: Throughout the follow-up period, 2675 deaths were recorded. After all adjustments, an association was observed between a sleep duration of 8 hours or more and all-cause mortality (HR, 1.10; 95% CI, 1.01 to 1.20). However, no such association was detected in the stratified analysis for the subgroups based on comorbidity status. Conclusions: Long sleep duration was found to be associated with all-cause mortality among Koreans, even after adjusting for comorbidities. Additional studies are required to explore the mechanism underlying the association between sleep duration and major causes of mortality.
