This study examines how individual, familial, and social factors are associated with persistent very low fertility in Busan Metropolitan City and contemplates family-friendly environments and social strategies for fertility increase. Fertility decline in Busan Metropolitan City recorded the lowest birth rate nationwide recent years among metropolitan cities and provinces in Korea. Birthrates are low partly because of multiple factors such as high age at childbearing and at marriage, decline in marriage, high divorce rate, the phenomena of marriage avoidance among unmarried women, traditional gender role attitude of men, low domestic work participation of husbands among dual career couples, low marital satisfaction and family life satisfaction, abortion, and more broader attiributes such as family policy, availability of childcare, education expenses, and family-friendlyness of a society. In addition, women of dual career couples in Busan strained from domestic work overload under traditional norms of gender role, and marital satisfaction recorded below average nationwide along with espeacially low marital satisfaction of wives compared to that of husbands. Major aspects of implications and considerations for higher birth rate and family friendly policy in Busan are discussed.

Urban densification has necessitated the development of subterranean spaces such as subway networks and underground tunnels to facilitate the dispersal and movement of populations. Development of these underground spaces requires excavation from the ground surface, which can induce groundwater flow and potentially lead to ground subsidence and sinkholes, damaging structures. To mitigate these risks, it is essential to model groundwater flow prior to construction, analyze its characteristics, and predict potential groundwater discharge during excavation. In this study, we collected meteorological, topographical, and soil conditions data for the city of ○○, where tunnel construction was planned. Using the Visual MODFLOW program, we modeled the groundwater flow. Excavation sections were set as drainage points to monitor groundwater discharge during the excavation process, and the effectiveness of seepage control measures was assessed. The model was validated by comparing measured groundwater levels with those predicted by the model, yielding a coefficient of determination of 0.87. Our findings indicate that groundwater discharge is most significant at the beginning of the excavation. Additionally, the presence of seepage barriers was found to reduce groundwater discharge by approximately 59%.

Recently, the rapid increase in vacant houses in urban areas has caused various problems such as worsening urban landscape, causing safety accidents, crime accidents, and hygiene problems. According to the Statistics Korea Future Population Estimation results, the growth rate of Korean population and households is expected to continue to decrease, which is likely to lead to an increase in the occurrence of vacant houses. If the problem caused by the occurrence of vacant houses is neglected, it causes not only a physical decline such as a deterioration of the residential environment but also a social and economic decline. In order to solve this problem, it is necessary to grasp the spatial distribution characteristics of vacant houses at the local level considering the existence of regional characteristics and spatial influence. Therefore, in this study, in order to measure global spatial autocorrelation, the analysis was conducted centering on the old downtown area of Busan, where there are many vacant houses through Moran's I and Geographically Weighted Regression(GWR). In addition, the distribution of vacant houses in different spatial units in Eup_Myeon_Dong and Census was analyzed to evaluate the possibility of Modifiable Areal Unit Problem(MAUP), which differ in the results of spatial analysis as the spatial analysis units change. As a result of the analysis, the occurrence of vacant houses by Eup_Myeon_Dong in the old downtown area of Busan had spatial heterogeneity, and the spatial analysis results of vacant houses were different as the spatial analysis units were different. Accordingly, in order to understand the exact distribution characteristics of vacant house occurrence, spatial dimensions using the GWR model should be considered, and it is suggested that consideration of the MAUP is necessary.

Purpose: This study used a nonequivalent control group pre-post test design to analyze how a death preparation education program helps middle-aged adults deal with life and death anxiety. Methods: We studied 83 adults at the age of 40 to 65 years. An experimental group of 38 people participated in the death preparation education, and a control group of 45 people did not. The death preparation program comprising four sections was given for four hours per week, and the program ran for 11 weeks. Data were analyzed by descriptive statistics, t-test, ${\chi}^2$ test, Fisher's exact test, and ANCOVA using SPSS version 17.0. Results: The death anxiety score of the experimental group was significantly lower than that of the control group (P<0.000). The quality of life did not show significant difference between the experimental and control groups (P=0.188). Conclusion: It was confirmed that the death preparation education program is effective in alleviating death anxiety. Although the program was confirmed as a necessity for the middle-aged adults, repeated observations with a wider range of experimental group is needed to collect objective and solid data. Death preparation education for middle-aged adults is expected to be more widely provided, starting from local health facilities.

The purpose of this study is to investigate factors that affect the suicidal ideation of the people with mental disabilities. To this end, the independent variables were analyzed by categorizing them into individual psychological factors, social factors, and demographic characteristics. The analysis data include 969 people with mental disabilities who participated in the 2017 Ministry of Health and Welfare's Research, 'Survey on the Current Status of Mental Disabilities in Community'. The analysis method was frequency analysis, descriptive statistics, and hierarchical multiple regression analysis with SPSS 23.0. As a result of the study, in terms of individual psychological factors, the higher the depression and the lower the mental health confidence, the more suicidal ideation increase. In terms of social factors, the more unregistered disabled groups, the more exposure to violence and discrimination, and the more they live in large cities, the higher their ideation of suicidal. The regression model explained 26.9% of suicidal ideation. The practical and policy implications for the prevention of suicide of the people with mental disabilities based on these results are as follows: First, social factors should be evaluated and considered together, rather than focusing only on individual psychological factors, in seeking policies and intervention programs that reduce suicidal ideation in the people with mental disabilities. Second, in seeking suicide prevention policies for the people with mental disabilities, Protection & Advocacy services should be provided to reduce violence and discrimination experiences. Third, in order to reduce the suicidal ideation of the people with mental disabilities, the mental disability registration system should be reorganized, and policy alternatives should be devised so that those experiencing mental distress can be included into the system.

Using the 2021 Korea Housing Survey Data, this study compared and analyzed the factors influencing the residential mobility of residents in public and private rental housing by population and social characteristics, economic characteristics, and housing characteristics. The analysis results are as follows. As a result of descriptive statistics analysis, it was found that private rental households were young and economically active. While the proportion of apartment residents and new housing, and the level of housing satisfaction were low, the level of housing insecurity was high. Through logistic regression analysis, significant factors influencing the residential mobility of private and public leases were analyzed. In terms of demographic and social characteristics, private leases were affected by marital status, the number of household members, the age of the household head, and the residential area, while public leases were affected by marital status and the age of the household head. In terms of economic characteristics, private leases were affected by assets, debt, and housing management costs, while public leases were affected only by debt. In terms of residential characteristics, private leases were affected by periods of homelessness, housing satisfaction, housing insecurity, and a sense of homeownership, while public leases were affected by housing type, years of construction, housing satisfaction, housing insecurity, and a sense of homeownership.

The purpose of this study was to examine the differences in the direct medical expenditure of community residents according to their physical activity level. The quota sampling method was used to select samples from a youth community center, senior center, community cultural center, and community recreational sports center in G city in Gyeongbuk-do. Of the 773 questionnaires distributed, 716 were completed. The questionnaires consisted of the demographic characteristics, regular exercise and physical activity levels, health status and medical costs. While the beneficial effect of regular exercise and physical activity on dental costs was not (significant), its effect on the costs of visiting hospital services was (significant). The mean differences in the total monthly direct medical expenditures on outpatient services and medicine for those with very high, high, moderate, low, and very low levels of physical activity were 7,500, 26,299, 47,517, 9,314, and 9,9978 won, respectively. The result of this study supported the findings of previous studies that regular exercise and physical activity. are not associated with the reduction of medical expenditure.

The necessity of aggregate resources in Korea has been increased with a rapid economic growth since the 1990s. Construction activities have been increased drastically for last two decades. Such economic activities are much concentrated at big cities in Korea, and recently new neighbouring cities, such as multifunctional administrative city, enterprise city and innocity, are under construction at the surroundings of the cities. This new urbanization asked for an appropriate supply of raw construction materials such as cement, sands and gravels. The aim of this study is to understand and discuss the analysis and prospect of supply and demand of domestic sand and gravel. On the early years, 1990s, about 25% of the total consumption of these sands and gravels comes from riverine deposits; 20% to 25% from marine sands, 40% to 45% from forest rocks and the rest 5% to 15% from old fluvial deposits and crushed rocks. But nowaday the river aggregate, including both sands and gravels of a present river channel and those of the old fluviatile system are decreasing, while the crushed and forest aggregates and marine sand are now the main source of infrastructure resources. Thus it is increasingly necessary to investigate the forest and crushed aggregate resources potential in Korea where a current analysis indicate that the supply of riverine aggregates gradually decreases.

This study explores school location, school environment, educational conditions, and appropriate scale of schools in the context of Sejong City's development area and identifies effective school establishment plans based on the analysis of the needs of the educational community. The research questions for this study include, first, what is the change trend in the number of students as a result of the opening of schools in the development area of Sejong City to the present, and what differences are there between Sejong and other new cities? Second, what challenges arise in school location due to the occurrence of oversized schools and undergraduate institutions? Third, what challenges arise in school location that would limit the ability to create a safe school environment? Fourth, what aspects need to be improved in school location decisions to promote proper placement? A survey was conducted among parents and faculty members to collect data. The findings revealed that first, when establishing a school, identifying an appropriate location for the school was the top priority of the respondents. The second was the proximity of the school to dense housing, with a parent drop zone next to the school site. Third, to address the issue of lack of playgrounds and special class and care classes, respondents called for various measures such as securing school sites within a certain area. Finally, integrated operation schools and school facilities are required in preparation for decreasing school-age populations due to low birth rates.

Objectives: We aim to identify factors associated with unmet dental care needs in older adults and explore the impact of time, economic and physical constraints on each. Methods: The analysis was based on the 2023 Community Health Survey. Statistical analyses were conducted using chi-square test and multinomial logistic regression for 65,952 people aged 65 years and older. Results: First, we looked whether subjects experienced unmet dental care needs and found that 8.4% did. Second, according to the type of unmet dental care needs, 54.1% of the time, economic, and physical constraints were economic constraints. Analyzing each of the time, economic, and physical constraints, we found that time constraints were associated with younger age. For economic constraints, lower education level and health security type of recipients in medical aid program were more likely to experience unmet dental care needs. In terms of physical constraints, those living in rural areas were more than three times more likely to experience unmet dental care needs than those living in urban areas. Conclusions: The results showed that time constraints were related to age, economic constraints were related to household income level, and physical constraints were related to residential area.
