  • The article demonstrates a method of studying human health and nutrition by applying a multi-disciplinary approach and examines how humans developed and survived by adjusting to their environment. This process involves physiological, cultural and genetic adaptation both independently and interactively. This study postulates that a sound human health may be the result of balance between nutrition and environmental conditions. It is noted that there is a positive correlation between malaria and fava bean intake, and sickle cell anemia and cassava intake. It is also suggested that the difference in disease structure in soybean and non-soybean consumption cultures can be explained by an ecological approach to studying nutrition. This study further suggest that the relationship between nutrition and socio-cultural system. epidmiological study of nutrition and cultural environment nutrition and conceptual characteristics, nutrition and food intake pattern, nutrition and health sociological functions and the physioloical, cultural and genetic adaptation can all be stimulating research subjects to be studied form and ecological point of view. This article also includes the results from a series of ecological studies conducted by the author investigating the relationship between nutritional status of Korean breast-feeding mothers and the composition of the human milk and also the Vitamin D status of Korean and their lifestyle.

  • This study investigated a long-term variation trend of water quality, fish compositions, and ecological health conditions in the Gwanpyeong stream located in the nearby Daejeon metropolitan city to understand the impact of urban development projects on the aquatic ecosystem. The sampling was made in four surveys (2009, 2010, 2016, 2019) before and after urbanization. The urban development was conducted in 2008, resulting in the stream's ecological disturbance, and the stream restoration was conducted in 2012. Thus, stream monitoring was conducted to analyze the ecological trends before and after the restoration. The multi-metric models for Fish Assessment Index(FAI) and necropsy-based Health Assessment Index(HAI) were applied in the fish community and organ-level, respectively, to assess the ecological health of the stream. Minimum turbidity and chlorophyll-a(Chl-a) occurred in the mid-stream(St. 2), and this was probably due to rapid current velocity in the riffle zone. We collected 18 fish species, and the dominant species was Zacco platypus (40.6%). In 2016 immediately after the stream restoration, the relative proportions of sensitive species and insectivore species were the highest along with highest values in the species diversity and species richness index, resulting in the best condition in the ecological health, based on FAI model values. However, the ecological health, based on the FAI, became worse in the latest survey conducted in 2019. The analysis of the HAI model based on the organ-level approach showed skin erosion in the fish of upper stream, kidney defects in downstream, and the liver and gill defects observed in all sites, indicating that the anatomical health was also affected.

  • This paper describes progress on formulating a national asbestos profile for the country of Vietnam. The Center of Asbestos Resource, Vietnam, formulated a National Profile on Asbestos-related Occupational Health, with due reference to the International Labor Organization/World Health Organization National Asbestos Profile. The Center of Asbestos Resource was established by the Vietnamese Health Environment Management Agency and the National Institute of Labor Protection, with the support of the Australian Agency for International Development, as a coordinating point for asbestos-related issues in Vietnam. Under the National Profile on Asbestos-related Occupational Health framework, the Center of Asbestos Resource succeeded in compiling relevant information for 15 of the 18 designated items outlined in the International Labor Organization/World Health Organization National Asbestos Profile, some overlaps of the information items notwithstanding. Today, Vietnam continues to import and use an average of more than 60,000 metric tons of raw asbestos per year. Information on asbestos-related diseases is limited, but the country has begun to diagnose mesothelioma cases, with the technical cooperation of Japan. As it stands, the National Profile on Asbestos-related Occupational Health needs further work and updating. However, we envisage that the National Profile on Asbestos-related Occupational Health will ultimately facilitate the smooth transition to an asbestos-free Vietnam.

  • This study assessed the ecological health of border areas using the ecological health index and suggested Indicators for maintaining and promoting ecological values. We analyzed the change trends, pressures, and resilience of ecosystems and services in border areas, and identified their current status and sustainability. The main findings were: (1) ecological assets and ecosystem services in border areas could be compared through ecosystem health assessment; (2) it can be used to set priorities for management and conservation by identifying the relative importance and vulnerability of ecosystems and ecosystem services in each border area; and (3) the index presented in this study can be judged to have explanatory power for the characteristics of border areas and ecosystem health when compared to previous studies. Limitations of this study include the lack of literature and statistical data at the local government level and the resulting limited application of evaluation methods, which limited direct regional comparisons. To overcome the research limitations, further studies are needed, such as establishing ecological information in border areas, mapping and assessment of ecosystem services, and developing and applying assessments that reflect the opinions and participation of various stakeholders. This study was the first attempt to assess the health of ecosystems and ecosystem services in border areas and provided an important baseline for future changes in border areas. In the future, it will be helpful in national and local government policies and ecological assetecosystem management by supplementing insufficient information and presenting clear goals.

  • The purpose of this study was to identify the educational and ecological factors (environment and infra-structure) associated with workers' participation to safety and health education at work (SHEW) based on the PRECEDE constructs. A total of 590 workers (484 in manufacturing and 106 in construction companies) finished the self-administered survey. Survey packets were delivered to the safety and health manager (SHM) in survey companies and the SHMs conducted the self-administered survey in their companies. The questionnaire includes demographics, epidemiological constructs, and educational and ecological constructs based on the PRECEDE model. Participation to SHEW was better in the manufacturing sector than in the construction sector (p<.001). Environmental, reinforcing, and enabling factors were better in the manufacturing companies than in the construction companies. Male worker, better perceived efficacy of SHEW, higher social support for SHEW, assignment of SHM at work, and better safety and health management level at work were significantly associated with workers' better participation to SHEW (p<.05). Those factors accounted for 45.9% of total variance of workers' participation to SHEW.

  • This study evaluated ecological health, using various biomarkers and bioindicators, of pale chub (Zacco platypus) as a sentinel species, in Daejeon Stream, South Korea, during AprilMay 2011. The biomarkers and bioindicators were compared among three sites of control: Reference ($C_z$), transition ($T_z$), and the urban zones ($U_z$); and the 7-Ethoxyresorufin-O-deethylase (EROD) activity, DNA damage, acetylcholinesterase (AChE) activity, and vitellogenin (VTG) concentrations were more significantly increased in the $U_z$ than in the $C_z$. Also, physiological markers such as condition factor, liver somatic index, visceral somatic index, and gonad somatic index were significantly increased in the $U_z$ than in the $C_z$. For the health assessments, three categorized parameters of blood chemistry, molecular biomarkers, and physiological bioindicators were standardized and calculated as a star-plot, representing values of Integrated Health Response (IHR). Values of IHR had more significant (P<0.05) increases in the $U_z$ than any other zones, indicating an impairment of ecological health by organic matter, nutrients (N, P), and toxic chemicals. This study is based on low levels of biological organization approach of molecular and physiological biomarkers and bioindicators, so further study of high-levels of biological organization approach such as community and population is required for overall range of health assessments. The approach of IHR values, however, may be useful in providing early warning of future impacts on ecological health.

  • Preliminary ecological environmental assessments including physico-chemical constituents, water quality, fish fauna analysis, physical habitat health, and ecological health assessment were conducted as a primary step for Jeungchon micro-habitat ecosystem restoration in 2012. Water chemistry analysis of conductivity, dissolved oxygen, chlorophyll-a and etc. indicated that there were no significant differences(p < 0.05) among 6 sites between the headwaters and downstream. Multi-metric model analysis of Qualitative Habitat Evaluation Index(QHEI) showed that brooklets were at "good condition" as a mean QHEI of 158.7(n = 6) and the longitudinal differences of the model values between the sites were minor(QHEI range: 153 - 165). Total fish species and the number of individuals were 12 and 481, respectively, and dominant species were Zacco platypus(49.5%) and Zacco koreanus(36.8%). Tolerance guild analysis showed that the proportion of sensitive species($S_S$) had a negative linear function[$S_S=86.35-0.31(D_H)$; $R^2$ = 0.892, p < 0.01] with a distance from the headwaters, while the proportion of tolerant species($T_S$) had a positive linear function($R^2$ = 0.950, F = 90.28, p < 0.001) with the distance. Trophic feeding guild analysis showed that the proportion of insectivore species($I_n$) had a negative linear function($R^2$ = 0.934, p < 0.01) with a distance from the headwaters, while the proportion of omnivore species($O_m$) had a positive linear function($R^2$ = 0.958, p < 0.001) with the distance. Index of Biological Integrity(IBI) model, based on fish assemblages, showed a "fair condition" as a mean IBI of 23(n = 6), and there was a distinct differences of ecological health between the headwaters(S1 = 30; "good condition") and the downstreams(S6 = 14; "poor condition"). Overall, the preliminary environmental impact assessments suggest that water quality, physical habitat conditions(QHEI model), and ecological health(IBI model) were maintained well, even if the state was not an excellent conditions.

  • Objectives: Residents of a single room occupancy (Jjok-bang) in Seoul are at high risk of having mental health issues. The majority of residents live in single households with past traumatic experiences including self-deprivation and social exclusion. This study was to investigate the association between mental health and socio-ecological factors at the intrapersonal and community levels. Methods: We conducted face-to-face surveys in Dongja-dong Jjok-bang area in June, 2014. Of 78 participants, 76% were male and the mean age was 60 years (SD=11.53). A multiple regression was used to analyze the association among depression, a sense of well-being, socio-ecological factors, and perceived empowerment and community solidarity. Results: Perceived empowerment (${\beta}=0.83$; 95% CI=0.40, 1.26) and community solidarity (${\beta}=0.52$; 95% CI=0.04, 1.01) were positively associated with a sense of well-being. Participants with empowerment (${\beta}=-2.55$; 95% CI=-4.86, -0.23) and those with community solidarity (${\beta}=-2.36$; 95% CI=-4.94, 0.21) were negatively associated with being depressed. Conclusion: Mental health of the residents in Jjok-bang was more influenced by empowerment and community solidarity than socio-demographic factors. It is necessary to improve public health infrastructures that can enable the residents to enhance empowerment and community solidarity utilizing socio-ecological perspectives.

  • The ideal housing in the 21st century means that it can provide people with the balanced life between nature and human life, while is possible through the systematic harmony of nature, environment, and human. As our society increasingly pays attention to the importance of environment, environment friendly houses and ecological dwellings are being built. If we add our own cultural environment attribute and historical identity to the ecological housing, we can create the most unique Korean ecological architecture. This study examines ecological interior expression methods from the traditional housing architecture which started out of nature, in order to find out an ecological approach in the interior design of the dwelling space. Based upon this examination, it mainly focuses on how these methods can be applied to a modern housing architecture. From an ecological perspective, the traditional house interior has two distinct characteristics; nature friendly and human friendly, because it considered nature and human harmoniously. The interior of the traditional housing can be divided into three types; nature friendly, health friendly, and human friendly. Finally, this study investigates the ecological value of the three types and application of them to modern housing. It will help to find out the harmonious way of building a house harmonizing both nature and human. Especially, considering that the nature is being destructed and the health of human is deteriorating due to the destruction of the nature, this study will show a feasible alternative to build the most Korean style of environmental architecture.
