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.

The purpose of this study was to examine and compare factors affecting the subjective life expectancy among the elderly, and to suggest health practice and social welfare service implications for later life. A total of 4,483 seniors from the 6th wave(2016) of the Korean Longitudinal Study on Aging (KLoSA) were used for analysis. The subjects were divided into three age groups: the young-old (n=2,106, 65~74 years), middle-old (n=1,803, 75~84 years), and oldest-old (n=574, 85 years and older). Control variables were sociodemographic factors and health status factors. Independent variables were health promotion behavior, cognition of public care, participating social activity, economic activity, and receiving basic pension. The data were analyzed using hierarchical multiple regression. The main results were as follows. Health promotion behavior was associated with the young-old. Social activities and economic activity were associated with the young-old and middle-old. Receiving basic pension had a significant impact on all age groups. In the middle-old, significant results were focused on socio-demographic and health status factors compared to other groups. The results of this study will provide basic data for the elderly policy and welfare service and will help to find and improve the important factors for the life of the elderly.

Korea's port development adjusts the completion time and size of port facilities according to the future port throughput. The current port development system, which is referred to as "throughput-linked port development (Trigger Rule)", has received positive evaluation for efficiently executing the limited port development budget. Recently concerns have been growing over deteriorating service levels in port facilities in Korea due to accelerated aging of terminal facilities. However, the current port development system does not possess any standard for assessing the level of service and utilizing development indicators. The purpose of this paper is to calculate the Port Service Index (PSI) by selecting indicators to measure the Level of Service (LOS) of ports and deriving weights between the indicators, so that the current "throughput-linked port development (Trigger Rule)" can be linked with the level of service. Based on the result of analysis on a variety of preceding studies, the ship waiting rate, berth productivity, ship turnaround time and ship productivity were selected as four indicators to constitute the Port Service Index. The AHP and entropy methodologies were used to derive weights for each of four indicators which were later combined to calculate the comprehensive weight. The calculation formula of the Port Service Index (PSI) was derived by using the aggregated weights of each indicator, based on which the LOS of domestic container and bulk terminals were evaluated and this measurement result was divided into 6 classes to define each LOS. This paper contributes to draw the improvement measures for port development system that are able to connect the quantitative indicator of throughput, as well as a qualitative indicator of the level of "service".

The word "Loss" means being deprived a person's meaningful property, people or idea by irresistible force, and it is not avoidable in one's life. Especially, the elderly have higher possibility to experience this "Loss" than any other age groups on account of their characteristics. Feeling grief of loss after going through any kind of loss is natural and normal. However, if someone has severe trouble with overcoming this grief, it would affect negatively to his/her psychological or social inelastic. Therefore, we tried to find out which factors consists the "Grief of loss" and how it affects on the elderly's quality of life, especially on the sense of ego-integrity through this study. 97 of the elderly over age 65 participated in the survey and the results as follow; grief of loss is classified into four factors, 'economical loss', 'loss from being parted by death', 'loss of physical functions' and 'loss of relations'. These four factors of "Grief of loss" showed negative correlations with the scores of the sense of ego-integrity factors except 'acceptance of death'. Especially, the 'economical loss' affects on every factor of the sense of ego-integrity negatively except 'acceptance of death' and 'acceptance of aging'. Moreover, 'loss of physical functions' and 'loss of relations' affect negatively on elderly's satisfaction to their lives. On the other hand, the 'loss from being parted by death' of "Grief of loss" and 'acceptance of death' of the sense of ego-integrity showed no statistically significant effect in every process of analysis.

The aging of plant structures due to industrialization in the 1970s has increased the demand for blast demolition. While blasting can reduce exposure to environmental pollution by shortening the demolition period, improper blasting design and construction plans pose significant safety risks. Thus, it is vital to consider optimal blasting demolition conditions and other factors through collapse behavior simulation. This study utilizes a 3-D combined finite-discrete element method (FDEM) code-based 3-D DFPA to simulate the collapse of a chimney structure in a thermal power plant in Seocheon, South Korea. The collapse behavior from the numerical simulation is compared to the actual structure collapse, and the numerical simulation result presents good agreement with the actual building demolition. Additionally, various numerical simulations have been conducted on the chimney models to analyze the impact of the duct size in the pre-weakening area. The no-duct, duct, and double-area duct models were compared in terms of crack pattern and history of Z-axis displacement. The findings show that the elapse-time for demolition decreases as the area of the duct increases, causing collapse to occur quickly by increasing the load-bearing area.

South Korea faces a declining population and rural areas vanishing due to urbanization. Infrastructure, especially medical facilities, may not be sustainable for a long-term. This may impact vulnerable groups like children, teens, and the elderly, worsened by an aging population and low birth rates. Gangwon-do, notably Chuncheon-si, suffers from rural depopulation and poor healthcare self-sufficiency. In this paper, using 2SFCA(Two-Step Floating Catchment Area), we analyze healthcare access in Chuncheon-si, identifying gaps and vulnerable areas. LISA analysis helps map medical vulnerability, considering patient demand and supply. The Gini coefficient assesses spatial inequality. We propose distributing healthcare services and personnel based on age and region. The aim is to identify locations for additional hospitals catering to the elders, Infants, Children, and Adolescents,considering spatial accessibility.
