Health Impact Assessment based on municipal law is performed and written in the sanitary and public health part in the current environmental impact assessment. Residential development projects such as housing site development etc., are not subject to health impact assessment under Article 13 of the Environmental Health Act. However, health impact assessment is conducted partially based on the review that health impact assessment targets which are identified among substances emitted from pollutants nearby industrial complexes should be assessed risk (including carcinogenic and non-carcinogenic) at the stage of the environmental impact assessment consultation. Although residential development projects do not have plans for pollutant emitting facilities that emit hazardous air pollutants, there is a possibility that residents might be affected by pollutants from industrial complex near residential area in the future. In this study, Health impact assessment was conducted to examine the impact on residents in planned areas by analyzing previous residential development projects. We predicted future impact by using the literature survey results on surrounding area (case1) and conducting contribution analysis (case2) and predicting exposure concentration of carcinogenic substances applying Atmospheric Diffusion Model (AERMOD). By this study, we concluded that applying on-site survey, contribution analysis and prediction of exposure concentration by using AERMOD complementarily will be effective to assess the health impact to the receptors by pollutants from industrial complexes near the planned zone.

This study evaluated the screening level assessment of ecological health using four biomarkers and four bioindicators of Misgurnus anguillicaudatus as a indicator species in agricultural area of South Korea during May-June 2011. The endocrine disrupting chemical (EDC) indicators, such as vitellogenin (VTG) and gonado-somatic index (GSI), were not significantly changed in the agricultural site (p>0.05), indicating no effects. The biomarkers and bioindicators were compared between two sites of reference site (RS) and the agricultural site (AS) for screening assessment of ecological health. The ethoxyresorufin-O-deethylase (EROD) activity, acetylcholinesterase (AChE) activity, and DNA damage were significantly changed in the AS compared with the RS (p<0.05). But the individual level bioindicators such as condition factor (CF), hepato-somatic index (HSI), and gonado-somatic index (GSI) were not significantly different from reference site (RS). These results may indicate impairments of ecological health by toxic chemicals and environmental conditions. Current this study is based on screening assessment of biochemical and individual level biomarkers and bioindicators, so further study is required additional biomarkers and population or community level bioindicators for more specific health assessments in agricultural areas.

Health impact assessment in the environmental impact assessment is conducted to determine whether to exceed the standard of each single substance and to establish appropriate reduction measures. In some development projects, although all substances in risk assessment meet the standard, exposure concentration is very close to it. However, considering the cumulative exposure of all substances, health effects are likely to occur considerably severer than those of individual substances, so it is necessary to prepare a concrete and improved methodology for integrating evaluation of emissions to identify the health effects actually exposed to receptors of living things. This study established the definition of cumulative risk assessment through overseas advanced cases and domestic and foreign literature reviews, and proposed a methodology for utilizing cumulative risk assessment considering health effects on multiple substances when developing industrial complexes. Applied by the proposed methodology, integrated indicators forfourtypes of hazardous heavy metals (Ni, Cr⁶⁺, Cd, As) emitted from industrial complexes were calculated, and applicability was tested with case of the industrial complex development projects conducted over the last decade (2011-2020).

The purpose of this study was to investigate the effect of oral health status on daily life of elderly women. The subjects of this study were 142 elderly women aged 60 years or older who were surveyed through questionnaires, interviews, counseling, and oral examinations. The SPSS program was used for frequency analysis, descriptive statistics and regression analysis. The results of the study showed that the number affected on daily life were 1.4 in average and the oral health condition was the highest at scaling (59.4%). When the oral status was unsatisfactory, it was found to be uncomfortable in daily life. In case of oral pain, oral status and poor removal of calculus, the number and frequency in daily life were increased. In conclusion, the oral health of elderly women can improve their daily life ability and affect the quality of life. Therefore, a systematic oral care plan is needed through the expansion of oral health promotion education for elderly women and the development of continuous preventive programs.

Health impact assessment in South Korea is carried out within the framework of Environmental Impact Assessment (EIA). And, public health and hygiene items in EIA as an evaluation of health impact items were designed to calculate the emission level of hazardous air pollutants from specific development projects, and the exposure concentration at major sites, and to assess the health risk associated with these projects. But, the assessment of the receptor characteristics around the development project is limitedly considered. The purpose of this study is to propose the method of calculation of potential exposed population and the use of it for public health and hygiene items in EIA. The data for the calculation of potential exposed population in South Korea were identified. And the calculation algorithm based on them was proposed. After that, in a development of industrial complex, a case analysis was carried out assuming the release of hazardous air pollutants. This study suggested that the concept of population risk should be applied in risk assessment utilizing the potential exposed population and as a future study, a standard of assessment of health effects for population risk should be established. Finally, the possibility of using this study as a location-limiting tool for the development project was presented through the method of calculating the potential exposed population. It is meaningful that this study presented a method for performing risk assessment from the perspective of receptors around a development project.

The Ministry of Environment(MoE) of Korea has recently established the Environmental Health Act. This Act contains a clause related to implementation of Health Impact Assessment(HIA). So, selecting a landfill which was expected to have an influence on human health among major development projects, this study carried out the human risk assessment due to inhalation exposure to landfill gas emission and attempted to measure the possibility of domestic application of HIA in the future. The process for HIA on landfill site extension focusing on human risk assessment is as follows: The first step is to presume and calculate the amount of landfill gas emissions using LandGEM, The second step is to carry out exposure assessment using K-SCREEN Model which is used for predicting the concentration in a conservative method. The last step is to carry out human risk assessment of carcinogenic and non-carcinogenic substances. It is considered that it is likely to apply a technique for human risk assessment due to inhalation exposure to landfill gas emission performed here more specifically in the case of implementing HIA. In addition, it is also believed that more systematic studies are needed to overcome some weak points and limits found in this study and if these weak points and limits are improved more reliable outcomes will be produced.

The development projects subject to health impact assessment (HIA) in the current environmental impact assessment (EIA) system are limited to some projects under Article 12 of the Enforcement Decree of the Environmental Health Act (Additional Assessment Objects Subject to Health Impact Assessment Items), but health impact-related matters are being evaluated and reviewed during consultation. In particular, when a development site is planned around some pollutant sources in a residential development plan, it is evaluated and reviewed whether the site meets the risk criteria through a current concentration survey of major hazardous air pollutants. This study prepared a quantitative method to confirm the validity of the location of the residential area to be developed in the residential development plan and proposed a plan to expand the project subject to HIA within the EIA procedure. A detailed methodology was proposed by reviewing the screening and scoping procedures of the EIA system, and a case analysis of the urban development plan discussed in the past was conducted to verify the methodology.

The purpose of this study was to examine the cognition-perception factors and oral health promotion behavior of dental hygiene and non-dental hygiene students in an effort to find out factors affecting their oral health promotion behavior. After a survey was conducted, the collected data were analyzed. The findings of the study were as follows: 1. In regard to cognition-perception factors of oral health, the dental hygiene students were ahead of the others in self-efficacy, control of oral health and benefits of oral health behavior. The latter felt there were more barriers to their oral health behavior than the former. 2. As to the practice of oral health promotion behavior, that behavior was more prevailing among the dental hygiene students than the others. Both groups restrained themselves from liquor and cigarettes. 3. Concerning the correlation between oral health promotion behavior and related variables, self-efficacy and control of oral health had a significant correlation to oral health promotion behavior. Better self-efficacy and better control of oral health led to better oral health promotion behavior and better practice of its subfactors 1, 2 and 3. 4. As a result of checking the variables affecting oral health promotion behavior and the subfactors of the variables, self-efficacy had the largest impact on factor 1, factor 2, factor 3 and oral health promotion behavior, and factor 2 was under the greatest influence of control of oral health. Based on above-mentioned findings, self-efficacy was identified as the cognition-perception factor that had the largest impact on oral health behavior. Therefore how to boost self-efficacy should be considered when oral health promotion programs are developed, and research efforts should be channeled into finding out in which way self-efficacy could be bolstered in association with each kind of oral health promotion behavior.
