This study was conducted to investigate the relationship between life satisfaction of the elderly and their transfer income (public transfer and private transfer income) using the 11th data of the Korea welfare panel study. In the analysis results, the public transfer income was analyzed to have a significantly positive (+) effect on the life satisfaction in the case of the elderly in general households while in the case of the elderly in low income households, private transfer income was analyzed to have a significantly positive (+) effect on life satisfaction. These results suggest that the public transfer income is 1,019,200 won (monthly average 849,000 won) in the case of the elderly in general households, and the public transfer income is found to have an effect to stabilize the income, which can be expected to increase the life satisfaction. However, in the case of the elderly in low income households, it was found to be 5,080,500 won (monthly average 424,000 won), half of the public transfer income of the elderly in general households. In the case of the elderly of low income households, it can be assumed that the private transfer income, which is the "uncomfortable" income source, fills up the unstable income stabilization gap and raises the life satisfaction. As a policy suggestion, first, by supplementing the basic pension system, which is an irrational part of public transfer income for the elderly with low income, it is necessary to design policy alternatives to enable economic stabilization of the elderly in low income households. Second, it is also necessary to actively review the introduction of income deduction plans for the transfer income of family members for the low income elderly households.

The purpose of this study is to explore factors influencing the poverty of the elderly in Korea. In spite the fact that poverty of the elderly is more serious than any other demographic group, this important issue is rarely studied. Using the 7-year accumulated data from the KLIPS(Korean Labor and Income Study), I combined the work history of the elders, their demographic characteristics and residence to estimate pooled data analysis of the elderly after reaching age 55 and who are also only living by themselves(only the elders). The results of this study are as followed: first of all, age, education, marital status, wealth, residence and work history are shown to be significant predictors for the poverty of elderly. Second, the results show that factors influencing the poverty is different depending on the elder's (demographic) characteristics. For example, age and marital status is a more important predictor in female than in male, and wealth and health status is a more important predictor in elders who do not have a spouse than in elders who do. Such results suggest that the policy of the poverty of the elderly which is only focused on elder's characteristic is limited. Therefore we can suggest that a policy which workable people can earn decent income and saving wealth for their elderly in job is needed. Especially, policies on the 'Working Poor' and reconstruct the current public pension system is very much needed.

Using 2006~2015 Korean Welfare Panel Survey data, this study analyzed the poverty reduction effects of social security benefits. The results show that social security benefits have substantial impacts on reducing the poverty gap. National Basic Livelihood Security, public pensions, and Basic Pension have relatively larger poverty reduction effects. Other benefits such as disability benefits, workers' compensation unemployment insurance, and childcare subsidies have much smaller poverty impacts. Two determining factors of the poverty reduction effect are (1)the amount and (2)the poverty reduction efficiency of social security benefits. With the expansion of the social security system in recent years, the poverty reduction efficiency has decreased in general. Due to a greater increase in the amount of benefits, however, the poverty reduction effect has gradually increased. In order to increase the anti-poverty effect of social security, it is important to find ways to improve efficiency while minimizing the disadvantages of the selectivistic welfare benefits.

This study was conducted on 1,174 retirees in their 50s and 60s nationwide using the 7th data of the National Pension Service's National Elderly Security Panel Survey. We were able to confirm the following results through the SPSS WIN 18.0 program.. First, men showed a higher level of education than women. From these results, it is expected that men will be better prepared for retirement. Second, men had spouses and two or more household members than women. According to previous studies showing that men are better prepared for retirement if they have a spouse, it is expected that men are better prepared for retirement. Second, 38% of men and 62% of women were voluntary retirees. Third, both men and women responded that their own and spouses should play the main role in preparing for retirement. Fourth, both men and women had very low rates of preparation for old age, economic independence, and public and private pensions. Among them, women were lower than men. Fifth, economic problem solving, health, and medical care were the priority as parts to be done for retirement in oneself and society. Based on these results, the directions for preparing retirees for retirement are as follows. First, education on wage peak system, retirement age extension and financial management for involuntary retirees is required, and guidance and management methods on health care and disease should be provided to address needs for health and health care. Women had more voluntary retirees than men, and they need to know why. Second, when both men and women are very poor at preparing for retirement, there should be job creation measures to ensure that they and their spouses are fully prepared for retirement.

The advantage of big data is to collect a large amount of data on the Internet and refine and use valuable data. That is, the unstructured data is processed so that the user can analyze and utilize it from a necessary point of view. This paper is a relatively small project and is based on unstructured data that can be closely applied to real life and used for marketing. The subjects of the experiment were modeled on lodging companies in the Seoul metropolitan area an hour away from Seoul, and analyzed for the increase in lodging rates before and after marketing using big data. As an experiment that shows the effects of increasing sales, reducing costs, and increasing returns by users, we propose a system to determine and filter whether data input in the process of analyzing big data such as social networks can be used as accommodation-related information.

This study predicts the economic activity level of the elderly in Korea using various machine learning methods. While the previous studies mainly focused on testing the relationship between the economic activity level and the life satisfaction or the social security system, this study aims at the accurate prediction on the economic activity level of the elderly using various machine learning methods and the forecast combination. Dependent variables such as the activity rate, employment rate, etc and independent variables such as the income, average wage, etc compose the dataset in this study. Five different machine learning methods and two forecast combinations are applied to the given dataset. The prediction performances of the machine learning method and the forecast combination varied across the dependent variables and prediction intervals, but it was found that the forecast combination was relatively superior to other methods in terms of the stability of prediction. This study has significance in that it accurately predicted the economic activity level of the elderly and achieved the stability of the prediction, raising practicality from a policy perspective.

In order to identify the factors and problems in which military sexual violence is a continuous and repeated blind spot, this study conducted a content analysis focusing on articles of military sexual violence incidents covered in Internet news from January 2010 to June 15, 2021. carried out. As a result of the study, structurally unequal power relations, authoritarian and closed military organizational culture, internal military response system that is distrustful of passive responses to sexual violence, and enveloping family-friendly investigations and tolerant punishment of perpetrators are blind spots despite the Ministry of National Defense's efforts to improve. factors that exist. Underlying this, the compensatory spirit caused by the conscription system and the negative effects of the patriarchal system are embodied in the national sentiment, suggesting that the sense of crisis of division and an overly permissive attitude toward the military act as a factor that slows change. As an improvement plan according to the results, it is necessary to entail the establishment of a civilian-centered judicial institution, strong punishment of perpetrators, and limited pension payment, as well as honorable punishment such as 'class demotion' in the military culture with a clear hierarchical relationship. Taken together, we can see that most military sexual violence is caused by a hierarchy, and it strongly suggests that the main cause of sexual violence is unequal power relations.

The burden of injury is widely considered to be very severe in our society. Nonetheless, we don't have enough data for injury surveillance. The objective of this research is to select and supplement CORE DATA for injury surveillance. For this purpose, this study had analyzed the literature such as the Quality Assessment Report about 'Causes of Death Statistics', 'Health Insurance Statistics' and 'Hospital Discharge Injury Surveillance' according to the six dimension of Statistics Quality. The analysis result is that 'Cause of Death Statistics' and 'Health Insurance Statistics' have the usefulness as the CORE DATA for injury surveillance. But there is a significant shortcoming in the Health Insurance Statistics, which is that there is a lack of the data about the external causes of injury. For supplementing the defect, this study proposes the system that the medical institutions should obligatorily report the external causes of injury when claim National Health Insurance Medical Care Expenses. As the results of this system, we can expect 'Establishing of Injury pyramid', 'Data Connecting with the National Pension' and 'Improving the Promptness of Injury Data'. And we expect the follow-up study for the realization of this system.

The permanent disability benefit(PDB) system whose purpose lies in helping affected workers with their self-realization through compensating them for their work-related injury or disease and facilitating their timely return to work is very important in terms of social welfare. Actually, the portions of PDB's in all WCI expenditures have been on the sharp increase. In spite of its positive aspects like this, however, an excessive amount of PDB's may have negative impacts on the affected workers' will to work or return to work, and increasing trends in the amount of PDB's payable in annuity will remain in an aging or aged society a potentially risky factor posing a threat to the soundness of WCI budgets. In this respect, the author attempted herein to identify the long-term reality of trends in the number of claimants entitled to PDB's and the amount of PDB's payable to them through making the long-term budget projections of PDB's; address problems with PDB's payable in annuity, which are or will potentially be one of the gravest burdens in securing the soundness of WCI budgets; and discuss how to optimize the amount of PDB's through studying & analyzing overseas cases and income replacement rates and what kinds of improvements are thinkable. It's recommended to reduce the absolute amount of benefits payable in annuity in a phased way considering claimants' life-cycle instead of sticking to the current system, which takes the form of lifelong pension plan.

Seafarers are exposed to various unpredictable maritime risks due to the spatial specificity of the working environment of the sea; thus, sufficient compensation for injured crewmembers is needed. However, Korea does not provide such compensation. Therefore, this study attempted to examine the Maritime Labor Act and the Industrial Accident Insurance Act of Germany, an advanced European social insurance country, and derive implications compared to Korea. First, we investigated how compensations are managed by a public institution in Germany and by shipowners in Korea. Second, regarding the contents of accident compensation, Germany does not only provide continuous treatment and care through various support systems, but also operates various programs to enable a return to ship work. In contrast, Korea has a temporary compensation system that allows shipowners to avoid liability for accident compensation, which is disadvantageous to shipwrecked seafarers. Finally, in Germany, workers' compensation insurance is public, judged considering the origin of work, whereas in Korea, it is determined by shipowners or insurance companies. Therefore, it is necessary to establish a public institution in charge of crew accident compensation to ensure proper compensation for crewmembers in Korea and to improve the Seafarers Act or system to provide compensation for additional medical care, disability pension, and rehabilitation benefits.
