Recently, ground subsidence has been continuously occurring in downtown areas, threatening the safety of citizens. Various underground facilities such as water and sewage pipelines and communication pipelines are buried under the road. It is reported that the cause of ground subsidence is the deterioration of various facilities and the reckless development of the underground. In particular, it is known that the biggest cause of ground subsidence is the aging of sewage pipelines. As an existing study related to this, several representative factors of sewage pipelines were selected and a study to predict the risk of ground subsidence through statistical analysis has been conducted. In this study, a data SET was constructed using the characteristics of OO city's sewage pipe characteristics and ground subsidence data, The data set constructed from the characteristics of the sewage pipe of OO city and the location of the ground subsidence was used. The goal of this study was to present a classification model for the occurrence of ground subsidence according to the characteristics of sewage pipes through machine learning. In addition, the importance of each sewage pipe characteristic affecting the ground subsidence was calculated.

The retirement of the Korean baby boomer generation has become a major factor in an aging society as a large proportion of the population has moved from the middle-aged to the elderly. In addition, after being busy working at a structured workplace for over 30 years, after retirement, they could not adapt to the unstructured environment, causing depression and leading to social problems such as the risk of suicide. research was needed. This study uses photovoice to in-depth research on the research question of how retirees' perception of death preparation, who wants to live a life prepared until death, is used. This is the purpose of this study. The study participants were 7 baby boomer retirees, the data were collected for 2 months, and the perception derived as a result of analyzing the photos, explanations, and in-depth interviews taken by the subject analysis method was used to prepare It was a necessity for education. In the discussion of this study, it is urgent to develop a death preparation education program that can help the baby boomer retirees, and I would like to suggest that the cooperation of local organizations in charge of the program is necessary. This study is meaningful in that it presents basic data in preparing social welfare policy measures for the elderly after retirement through the awareness of death preparations of baby boomer retirees.

The purpose of this study was to investigate biomechanical differences between young and old adults during downhill walking on a treadmill in order to understand the mechanisms of elderly falls. Eighteen healthy young females(YG: yrs: 21.17±1.5) and eighteen healthy old females(OG: yrs: 66.67±1.33) participated in this study. They were asked to walk at their preferred speed on a treadmill at level, 7.5° and 15° decline. OG walked more wobbly in the medial and lateral directions than YG(p<.05). As slope got steeper, OG had smaller ROM(range of motion) of ankle and knee joints compared with YG. However, there was no difference in ROM of the hip between OG and YG, but maximum extension angle of OG was smaller compared with YG(p<.05). Smaller extensor moment was generated on OG during downhill walking(p<.05). It was hypothesized that more risk factors would be found on older people compared to young people during downhill. However, older people actually walks with a safer strategy compared to young people during downhill. Finally, current findings about biomechanical characteristics of elderly walking would provide useful fundamental information for a follow-up study regarding the prevention of elderly fall during their daily life.

Due to the lack of judgement in an information processing on road sign, older drivers usually are having a hard time driving than young group. Furthermore, according to increasing in aging population, older drivers in Korea have been growing much faster. That means research for older drivers' characteristics and the number of guide name for road sign should be needed. In accordance with suggestions, this study was carried out the number of guide names for road sign with a variety of ages from the twenties to the seventies. For the sake of this study, statistical verification was conducted to confirm a change of speed, a reading time and a misreading rate with Driving Simulator and Electrooculogram tool. As the results of study, change of speed in the age range has shown that the higher the proportion of age, the lower the rate of velocity. Also reading time in the age range with regression analysis found that the higher the proportion of age, the higher the rate of reading time by 0.106sec. Finally, a binary logistic model was used to find the main factors. As the results, 4 number of guide names for road sign have been the best of them for older driver. The result of this study verified the importance of ideal guide numbers on road sign for older driver and proved itself to be an effective method to determine the road safety for the road signs.

Today, fishing villages are on the verge of extinction due to severe aging within the population and outward migration. Recent projects and studies targeting fishing villages viewed the fishing villages from an outsider-centered perspective, without a local-centered understanding of the village as a daily living space. Therefore, to understand the settlement environment of fishing villages, this study analyzed empirical data on the usage behavior of fishing village residents to gain insight into the characteristics of the outdoor space uses of residents in fishing villages. In this regard, a face-to-face survey was conducted among residents, and a village map drawn by the villagers showedthe spatial perception of the villagers. Empirical data on the behavior of fishing villagers using the village space was collected and analyzed through GPS. The study results suggested that residents of fishing villages tend to focus on productive activities, such as fishing, leading to a lack of awareness of other leisure activities and spaces. This monotonous pattern of space utilization within the village appears to stem from an absolute lack of available facilities within the target area. Therefore, in future village regeneration projects aimed at improving the quality of life for residents in fishing villages, it is essential to consider the residents' perception and utilization of space as a priority. The results of this study can be considered valuable foundational data for understanding the utilization of spaces within fishing villages and can be effectively utilized in planning initiatives to enhance quality of life.

The purpose of this study is to find out the degree of powerlessness factors among elderly and by examining the variables(perceived health status, ability of daily living activity, self-esteem, depression, family support, loneliness) which affect such factors. By searching for methods to improve the quality of life for the elderly, efficient nursing procedures can be developed, thereby leading to successful aging. For the study, we purposively collected 300 elderly above the age of 65, residing in the areas of Seoul, Inchon, and Daejeon. 266 samples, survived the data screening, were analyzed by reliability analysis, Spearman correlation, and a multiple regression. As the results, first, the correlated factors of the elderly's powerlessness included depression(r=.597, p<.01), loneliness (r=.423, p<.01), ability of daily living activity(r=.374, p<.01), perceived health status(r=-.304, p<.01), family support(r=-.384, p<.01), and self-esteem(r=-.420, p<.01). Second, factors influencing of powerlessness of them were to show in order of depression(β=.373), loneliness(β=.265), spouse(β=.099), family support(β=.090), monthly allowances(β=.013), these variables accounted for 45.7% of the variance of the elderly's powerlessness. Depression showed to be the most important of the powerlessness factors for the elderly. These findings suggest that nursing researchers need to consider important factors affecting the elderly's powerlessness and nursing interventions focusing on the issues need to be developed.

The purpose of study is to compare the level of participation of the elderly people in the activity of production between Korea and Canada and to identify the factors related to the participation of the elderly people in the activity of production between Korea and Canada. In order to conduct a comparative culture study two data sets were used; one was the 1999 Survey of Time Use collected by Korean Statistics Office and the other was 1998 Survey of Time Use collected by Canadian Statistics Office. Many countries have been collected a time use survey and used to study labor, welfare, and culture. Total number of 17,730 Korean and 2,729 Canadian between 55 and 84 were included to analyze the data. It is clear from the results that older people engage in various productive behaviors, particularly when the definition of activities is broadened to include unpaid work. It is also clear the overall productive contributions are higher among older Koreans than among older Canadians. While the focus in this study has been strictly on productive activities, the aging well literature suggests that the ability to remain independent in later life is enhanced through continued engagement in productive activities. It is thus critical that we better understand the nature of later-life activities and in particular the wide-ranging contributions made by older people. This is an important area of further exploration.

The purpose of this study was to explore the factors related to social participation of Korean young-old adults residing in urban area with a focus on the effects of various motivations. In addition, this study examined gender differences in the relationships between social participation and motivations of social participation. Self-oriented motivation, network-oriented motivation, and society-oriented motivation were considered as motivations of social participation. The study subjects were 836 men and 877 women aged 50-69. The data were collected through face-to-face interviews using structured questionnaires in 2009. Hierarchical regression analysis was conducted to examine the relationships between motivations and the level of social participation using the SAS program. Main results were as follows: 1) The network-oriented motivation and society-oriented motivations were significantly related to the level of social participation; 2) Although men and women significantly differed in the patterns of social participation, gender differences were not found in the relationships between the social participation and motivations. These findings imply that network-oriented motivation and society-oriented motivation are important for facilitating the social participation of Korean young elderly. Further implications were discussed.

The purpose of this study was to empirically verify the effects of spousal bereavement and complicated grief level on death anxiety of the elderly. The sample consisted of 1,998 adults who were aged 65 or older. Dependent variable was measured with the Death Anxiety Scale-Korean version (DAS-K). Independent variable was measured with both spousal bereavement and the Inventory of Complicated Grief-Korean version (ICG-K). Multiple regression analysis was performed using SPSS 23.0, adjusting for demographics, psycho-social and health variables. The results indicated that death anxiety level was lower among the bereaved with normal grief (p<.01) than non-bereaved. In contrast, death anxiety level was higher among the bereaved with complicated grief than non-bereaved (p<.01). The study result suggests that the most risky factor for death anxiety is complicated grief rather than the bereavement. Although the bereavement can be a universal experience, the severity and duration of symptoms after the bereavement may not be general. The unhealed emotional and physical pain after the bereavement stimulates death anxiety, and senior citizens who suffer from complicated grief often fail to integrate the bereavement and loss into reality, therefore, may not accept the death phenomenon itself. Anxiety and fear of death can emerge when they cannot acknowledge the bereavement. To manage complex sorrows and mitigate death anxiety, intervention programs should be provided to increase adaptability to the bereavement.

The purposes of this study are to examine the factors affecting retirement satisfaction, focusing on health, social activity and social security anticipation, and to compare the results between young-old and middle-old. A total of 860 retired people who live alone or live with their spouses were selected from 6th Korean Longitudinal Study of Aging, and binomial logistic regression analysis was used to analyze 416 young-old(aged from 65 to 74) and 444 middle-old(aged from 75 to 83). The results are as follows. First, there was no significant difference in retirement satisfaction between young-old and middle-old. Second, when factors affecting retirement satisfaction was examined, young-olds showed hgher retirement satisfaction with higher perception of health condition and mental health condition, and showed lower retirement satisfaction with higher expectation of long-term care insurance. Middle-old was likely to show higher retirement satisfaction when they had better perspective on physical and mental health condition. The results of the study show that health condition of elderly is an important contributing factor in determining retirement satisfaction of the elderly. Based on the results of the study, political and practical suggestions were proposed to improve retirement satisfaction.
