Health impact assessment is implemented within the Environmental impact assessment for the purpose of minimizing health damage by predicting the impact on human health following implementation of the development project. In health impact assessment, manual revision is required due to the lack of consistency in the method of estimating hazardous air pollutants emissions. This study estimated the emissions by calculating the emissions of hazardous air pollutants based on the actual industrial complex development cases and completed health impact assessments. As a result of risk assessment based on exposure concentration using CALPUFF model, the risk assessment results were different for each of the emission estimation methods, and manual improvement on the emission estimation method is needed.

Complementary and alternative medicine (CAM) has gained in popularity among cancer patients in recent years. The use of CAM in cancer patients is common with about one third of patients using some form of CAM in Western countries. The purpose of this study was to analyze the use of CAM and determine what factors affect to use CAM among cancer patients to provide CAM therapy information and assist therapy selection among various CAM therapies to cancer patients. The design of the study was descriptive cross-sectional, and data were collected using a 16-item questionnaire. This study was conducted in subjects with confirmed diagnosis of stomach, colon, liver, or pancreas cancer, in both out-patients clinics and inpatients setting in a tertiary hospital in Seoul Korea. As a result, among the participants, past or current CAM use was reported by 75%, which shows a statistically significant difference in income groups(P<0.05), but no difference in age and religion groups. The most common therapies use by cancer patients included traditional Korean medicine (32.1%), folk remedies (26.6%), exercise (14%), dietary supplements (11.6%), physical therapy (9.9%), diet therapy (5%), and meditation (4%). 77.8% of patients show satisfaction and 64.4% shows perceived effectiveness of CAM. Male patients with higher income, and previous treatment were more likely to use CAM. The main benefits from CAM reported by cancer patients were psychological improvement and symptom improvement. Of the cancer patients used CAM, 30.9% were dissatisfied, 25.8% did not have benefits from the use, and 7.6% experience side effects. Cancer patients who prefer CAM (more than 3 kinds) used it to cure cancer, on the contrary, the one who do not prefer CAM used to improve symptoms and psychological stability. The main sources of information about CAM were family and friends(54.4%), and media(24.5%), doctor and nurse(18.3%), and religion group(2.6%). Findings suggest that due to the relatively high use of CAM among cancer patients in Korea, this topic should be taken into account in the development of a holistic approach to cancer patients and efficient cancer patients management system and proactive and consistent management of CAM is necessary in the health care system in Korea.

Purpose: The purpose of this study was to evaluate severe periodontitis with tooth loss as a modifiable risk factor for Alzheimer dementia (AD), vascular dementia (VaD), and mixed dementia (MD) using the National Health Insurance Service-National Health Screening Retrospective Cohort database with long-term follow-up over 14 years. Methods: Multivariate Cox hazards regression analysis was applied to a longitudinal retrospective database, which was updated in 2018, to evaluate the association between severe periodontitis with few remaining teeth and dementia after adjusting for potential risk factors, including sociodemographic factors and comorbid diseases. Results: Among 514,866 individuals in South Korea, 237,940 (46.2%) participants satisfying the inclusion criteria were selected. A total of 10,115 age- and sex-matched participants with severe periodontitis and 10,115 periodontally healthy participants were randomly selected and evenly assigned. The results showed that the risks of AD (hazard ratio [HR], 1.08), VaD (HR, 1.24), and MD (HR, 1.16) were significantly higher in patients with severe periodontitis with 1-9 remaining teeth after adjustment for sociodemographic factors, anthropomorphic measurements, lifestyle factors, and comorbidities. Conclusions: Severe periodontitis with few remaining teeth (1-9) may be considered a modifiable risk factor for the development of AD, VaD, and MD in Korean adults.

Purpose: To identify the compliance level with therapeutic regimen among patients with hypertension residing in rural communities. Method: A descriptive-retrospective research design was employed. One hundred patients with hypertension using 8 Primary Health Care Posts under W Public Health Center were randomly recruited on the basis of being over 35 years of age. After obtaining written consent, the patients underwent direct interviews with a structured questionnaire carried out by 8 public health practitioners. Descriptive statistics and binary logistic regression were utilized. Results: In a binary logistic regression model adjusted for age, sex, education, income, and occupation, those who were receiving medication (OR=5.34), were undergoing a weight control program (OR=4.45), restricted alcohol (OR=9.93), or smoking cessation (OR=25.59) as recommended by medical or health professionals were more compliant (p<.05) while those under a low salt diet, exercise, and stress management were not significant statistically (p>.05). Conclusions: Further research should be conducted to validate these findings so as to facilitate the development of nursing intervention strategies for improving the compliance of hypertensive patients in respect to medication and life style modification.

Soil health can deteriorate through both contamination and remediation. Accordingly, revitalization processes are needed to reuse or recycle the remediated soil. The study was conducted to assess the changes in soil health parameters of heavy metals-contaminated soil during soil washing process. In addition, unit processes were proposed to improve the quality of the remediated soil relevant to its reclamation purposes, such as agricultural and forest lands. A total of 21 indicators were used to determine whether the soil health was degraded or recovered. The performance of 6 amendments in improving soil health was quantitatively evaluated according to their dosage and application duration. Finally, the experimental results were assessed by simple regression analyses to determine the statistical significance and relative performance of each amendment. The results indicated that 18 health indicators out of 21 deteriorated through the soil washing process. Based on the results, it is recommended that several effective amendments be complementarily combined and applied in real applications because use of single amendment does not likely improve the quality of remediated soils.

Background: This study aims to allow the development of efficient measures to improve occupational health of shift-working nurses focusing on job stress, health promotion behavior, resilience, and sleep disturbance. Methods: It was conducted on a subject panel of 137 nurses who were aware of the purpose of the study and agreed to participate. They worked three shifts at a tertiary hospital or a general hospital located in metropolitan city B. The collected data were analyzed by the independent t test and one-way analysis of variance and post-tested by Scheffe's test, Pearson's correlation coefficients, and multiple linear regression analysis using SPSS/WIN 25.0. Results: The significant influencing factors on sleep disturbance were of those whose subjective health status was 'normal' (b = 0.29, p < .001), 'not healthy' (β = .40, p < .001), who have job stress (β = .22, p = .003), and who have health promotion behavior (β = -0.17, p = .023). The overall explanatory power was 31.1% (F = 16.31, p < .001). Conclusion: Through this study, nurses' subjective health status and job stress of working shifts were found to be important factors influencing the sleep disturbance level, and the most influencing factor was identified as the subjective health status.
