Purpose: This study aimed to explore ecological factors and strategies for childhood obesity prevention targeting vulnerable children using a community-based participatory research (CBPR) methodology. Methods: The CBPR was conducted by following basic process steps. Participants were 12 community stakeholders such as community child center directors (n=4), vulnerable children's mothers (n=3), community health center officials (n=2), and lay health advisors (n=4); they were purposively sampled from K municipal county in Seoul, South Korea. The qualitative content analysis was performed to explore main themes of the ecological factors and strategies by using data obtained from 5 times of focus group interview. Results: Twelve ecological factors associated with childhood obesity prevention were identified: Intrapersonal factors including emotional overeating; interpersonal factors including permissive parenting style of children's eating behaviors; organizational factors including social workers' less educational opportunities; and community/policy factors including less government financial support. Four ecological strategies for childhood obesity prevention were addressed: Developing obesity prevention programs targeting vulnerable children' lifestyles; promoting parents' active participation in education; building healthy meal service environments through empowering social workers; and building supportive community environment and securing community resources for child obesity prevention. Conclusion: Our findings may be informative in terms of providing a comprehensive understanding of multi-level ecological barriers against vulnerable children' obesity prevention and, moreover, guiding multi-level strategies for preventing childhood obesity targeting children enrolled in community child centers.

The guarantee of transportation for elderly and handicapped people is increasingly necessary owing to their growing social and economic activity. In March of 2013, a partial amendment to the law for transportation of the vulnerable was made by the government, to make more convenient transport a legal requirement. The amendment describes standards for the installation of transport facilities, and its support available. However, the adjustment of low-floor bus routes is not included. Therefore, low-floor buses are operating without consideration for the handicapped. This study evaluates the current low-floor bus system user experience by considering the residential distribution of vulnerable customers and analyzing their reasons for using public transport. As a result of this work, adjustments to current bus routes are proposed. The residential distribution of vulnerable people has been assessed using the supporting materials of the urban renewal project in Busan City, and their reasons for using public transport have been collected by a survey of the target user groups. The results show that group A, which has good accessibility, was in high demand, but provided the most limited service. Whereas group C, which also has good accessibility but was in low demand, provided its service most frequently. The data show the supply and demand inconsistencies of low-floor buses, and the inefficiency of bus route allocation. Therefore, this study proposes improvements to current methods for the effective operation of low-floor buses.

Background: Few studies have assessed exposure to chemicals in the context of environmental vulnerability with a focus on exposure among populations living in certain geographical areas. Objectives: This study aimed to investigate cadmium exposure levels and kidney damage indices in environmentally and socioeconomically vulnerable populations, with further subgrouping according to economic status. Methods: Four areas were selected to represent geographical vulnerability (two environmentally vulnerable populations and two socioeconomically vulnerable populations). Among them, population groups with lower socioeconomic status (SES) were separately classified. Urinary cadmium (UCd), beta2-microglobulin (β2-MG), and N-acetyl-β-D-glucosaminidase (NAG) levels were analyzed in samples from 245 residents of these four areas. Results: Geometric means of concentrations of UCd (0.97~2.02 ㎍/g creatinine) in all selected populations (N, 245; mean age, 67.8~70.9 years old) were higher than the national reference values (0.39 for adults and 0.78 ㎍/g creatinine for people in their 60s). Participants with a lower SES had higher UCd and NAG concentrations than did non-low SES participants. In the lower SES group, there was a significant association between UCd and NAG concentrations; however, there was no such correlation in the non-low SES group. Conclusions: Consistent with the findings of previous studies evaluating chemical exposure and associated health effects in specific populations, the findings of this study suggest that individuals with a low SES may be more vulnerable to exposure and related health effects.

This study aims to study non-rechargeable wrist-type smart bands for those vulnerable to the digital environment. The transition to the digital age means improving the efficiency of human life and the convenience of management. In the digital age, it can be a very convenient infrastructure for the digital generation, but otherwise, it can cause inconvenience. COVID-19 is spreading non-face-to-face culture. The reality is that the vulnerable are complaining of discomfort in non-face-to-face culture. The core of the digital environment is smartphones. Digital life is spreading around smartphones. Technology that drives the digital environment is the core technology of the Fourth Industrial Revolution. The technologies are lot, big data, Blockchain, Smart Mobility, and AI. Related technologies based on these technologies include digital ID cards, digital keys, and nfc technologies. Non-rechargeable wrist-type smart bands based on related technologies can be conceptualized. Through these technologies, blind people can easily access books and manage their ID cards conveniently and efficiently. In particular, access authentication is required wherever you go due to COVID-19, which can be used as a useful tool for the elderly who feel uncomfortable using smartphones. It can also eliminate the inconvenience of the elderly finding or losing their keys.

This study aimed to identify a nutritionally vulnerable group and to examine their nutritional problems based on a relationship between socioeconomic position and nutritional status through life-course. A cross-sectional nationwide survey of 2005 Korean National Health and Nutrition Examination Survey (KNHANES) was used. A total of 8,930 participants aged $\geq$ 1 year were included. The socioeconomic position indicator was education level. Nutritional status was assessed by the percentage attainment of a dietary reference intake (DRI) and dietary quality based on nutrient intakes estimated by a 24 hour-recall data. Food insufficiency was examined by one-item food insufficiency questionnaire. The difference in nutritional status and food insufficiency according to educational level was tested by General Linear Model and Chi-square test, respectively. The nutritional status and food insufficiency was the worst during adolescence and older age than other period. Both quantity and quality of nutrient intakes was poorer in low education group than high education group. The prevalence of food insufficiency also was higher in low education group. The results were consistent across the life-course and sex. Based on these findings, we suggest that the development of various policy and strategies targeted to nutritionally vulnerable group is necessary to reduce nutritional inequality by socioeconomic position.

Purpose: The purpose of this study is to present an evacuation performance analysis model that can derive vulnerable evacuation spaces with considering the movement behavior as per the elderly groups in the event of a fire in a geriatric hospital. Methods: The evacuation characteristics of geriatric hospital users were investigated through the review of precedent studies. First, the occupant conditions and the evacuation scenario were set to analyze a study target hospital. Then, the evacuation simulation was carried out considering the group types and the density of each group. Finally, an evacuation performance analysis model according to the group type was presented based on the simulation results. Results: The results of this study are as follows: (1) The evacuation performance according to the group type is to be clarified through the suggested study model. (2) It is necessary to secure a ramp or an emergency elevator to distribute the evacuation personnel at the design stage because congestion occurs due to collisions between evacuees on the stairs and delays the evacuation time. (3) It is necessary to consider the evacuation stairs and openings of sufficient size by analyzing the frequency of congestion occurrence and the escape routes of occupants in advance to identify the space where the evacuation flow overlaps. Implications: It is expected that the study result is to be used as primary data for studies that consider the elderly and clustering evacuation behavior in the event of a fire in a geriatric hospital.

The purpose of this study is to examine the experience of case management practice for residents of low - income housing. The importance of the house for the vulnerable residents with homelessness is absolute, and case management that supports them to live as residents in the community is also very important. Nevertheless, the research so far has focused on the supply of affordable housing, the residential environment, the quality of life of the tenants, and the health, but there was a lack of interest in case management practices. In this study, we investigated the experience of case management practice by listening 10 case managers's experiences through FGI interview. As a result of the study, the case manager's experience is divided into four themes: 'Dilemma of support for the independent housing life after the facilities', 'Role competition between rent management and case management', 'Lonely practice for linkage and cooperation with the mainstream community support system', 'Double employment relationship and poor working environment' respectively. Based on their experiences, this study suggests practical and practical suggestions for case management of rental housing.

In the modern society, the number of people in disaster vulnerable groups is rapidly increasing such as the elderly, the disabled, foreigners, and children. The common characteristics of the groups vulnerable to disasters are that they live in residence types that are exposed to disasters because they are impoverished and if they are exposed to disasters, recovery is a slow process. The purpose of this study is to identify the new risk issues by performing risk issue analysis on the targets of disaster vulnerable group and provide base data for the development of the policies. For the research method, this study centered on the cases of children and pregnant women out of the disaster vulnerable groups and focused on the issue data of social media throughout the past 10 years ('10~'19) and performed social network analysis. As a result, first, the development of the issue showed relevance in the occurrence of specific cases. Second, the awareness about the types, targets, and management method of crisis management was analyzed. Third, an analysis was performed on the sentiment words that considered the solution measures of risk issues or the characteristics of the targets and it was analyzed that there were word that triggered negative emotions. Therefore, it is anticipated for the base data to be used for the government and also for the local government to build an effective crisis management system of the rapidly changing disaster environment on the basis of the sentiment analysis performed on the people of the nation as well as public awareness.
