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.

Using the 2001 Family Income and Expenditure Survey micro-data, this study analyses the anti-poverty effectiveness of public and private income transfers. In this study, the anti-poverty effectiveness of income transfers is summarized in two ways; 1) the poverty reduction effect of the income transfers, and 2) the poverty reduction efficiency of the income transfers. The poverty reduction effects are measured with several poverty indices including the head-count ratio, poverty gap, and Sen index. Using Beckerman's model, this study also analyses the poverty reduction efficiency of income transfers. This analysis documents substantial differences in the anti-poverty effectiveness of public and private income transfers. Although the private income transfers contribute more to reduce the head-count poverty ratio and Sen index than public income transfers, their differences are significantly reduced after the enactment of National Basic Livelihood Security Act. The results also reveal that the anti-poverty effectiveness of public and private income transfers vary by the types of families. In families headed by elderly and working aged, private income transfers have more anti-poverty effectiveness. But, public income transfers contribute more to reduce poverty than private income transfers among families headed by single adults with children. The results of this study suggest that recent changes in anti-poverty policies in Korea have been strengthened the Government's responsibility. And more importantly, to effectively reduce poverty among the poor families, anti-poverty polices must be designed to consider different family types.

The purpose of this study is to analyze the effectiveness and efficiency of social security benefits to poverty alleviation. To this end, this study analyzed the poverty alleviation effect of public pension, basic pension, child-rearing allowance, disability allowance, basic living security subsidy, EITC, and other government subsidies using 2019 Household Financial Welfare Survey. The analysis results are as follows. First, social security benefits lowered the poverty rate by 6.8%p. Second, in terms of the poverty gap reduction effect, the public pension for the elderly male households, the basic pension for the elderly female householder, and the basic guarantee for the working female householder contributed the most. Finally, in terms of poverty alleviation efficiency, about 33% of social security benefits contribute to narrowing the poverty gap. Social security benefits for female heads of households were found to serve as a function of alleviating poverty gap and for male heads of households to supplement household income. Based on these results, this study suggested the discovery of various poverty states, expansion of basic security for the female elderly, and the connection between the purpose of social security benefits and key targets.

Urban Informatics, the application of data science methodologies to the urban development and planning domain, has been increasingly adopted to improve the management and efficiency of cities. This paper introduces state of the art use cases in major cities including New York, London, Seoul and Amsterdam. It also introduces recent advances in using Big Data by multi-lateral institutions for poverty reduction, and startups utilizing open data initiatives to create new value and insights. Preliminary research performed on using Seoul's open data such as building permit data and health code violations are also introduced to demonstrate opportunities in this relatively new but promising area of research.

Agricultural water management has gained enormous attention in the developing world to alleviate poverty, reduce hunger and conserve ecosystems in small-scale production systems of resource-poor farmers. The story of food security in the $21^{st}$ century in India is likely t o be closely linked to the story of water security. Today, the water resource is under severe threat. The past experiences in India in general and in Andhra Pradesh in particular, indicated inappropriate management of irrigation has led to severe problems like excessive water depletion, reduction in water quality, water logging, salinization, marked reduction in the annual discharge of some of the rivers, lowering of ground water tables due to pumping at unsustainable rates, intrusion of salt water in some coastal areas etc. Considering the importance of irrigation water resource efficiency, Krishna Western Delta (KWD) of Andhra Pradesh was purposively selected for this in depth study, as the farming community in this area are severely affected due to severe soil salinity and water logging problems and hence, adoption of different water saving crop production technologies deserve special mention. It is quite disappointing that, canals, tube wells and filter points and other wells could not contribute much to the irrigated area in KWD. Due to less contribution from these sources, the net area irrigated also showed declining growth at a rate of -6.15 per cent. Regarding paddy production, both SRI and semi-dry cultivation technologies involves less irrigation cost (Rs. 2475.21/ha and Rs. 3248.15/ha respectively) when compared to transplanted technology (Rs. 4321.58/ha). The share of irrigation cost in Total Operational Cost (TOC) was highest for transplanted technology of paddy (11.06%) followed by semi-dry technology (10.85%) and SRI technology (6.21%). The increased yield and declined cost of cultivation of paddy in SRI and semi-dry production technologies respectively were mainly responsible for the low cost of production of paddy in SRI (Rs. 495.22/qtl) and semi-dry (Rs. 532.81/qtl) technologies over transplanted technology (Rs. 574.93/qtl). This clearly indicates that, by less water usage, paddy returns can be boosted by adopting SRI and semi-dry production technologies. Both the system-level and field-level interventions should be addressed to solve the issues/problems of water management. The enabling environment, institutional roles and functions and management instruments are posing favourable picture for executing the water management interventions in the State of Andhra Pradesh in general and in KWD in particular. This facilitates the farming community to harvest good crop per unit of water resource used in the production programme. To achieve better results, the Farmers' Organizations, Water Users Associations, Department of Irrigation etc., will have to aim at improving productivity per unit of water drop used and this must be supported through system-wide enhancement of water delivery systems and decision support tools to assist farmers in optimizing the allocation of limited water among crops, selection of crops based on farming situations, and adoption of appropriate alternative crops in drought years.

According to the National Statistical Office, the number of senior citizens aged 65 or over has exceeded 7 million as of 2017, and the number of senior citizens who live alone among them exceeded 1.3 million. Most of the senior citizens who live alone suffer from absolute poverty (68.5% of them has monthly income less than 500,000 won) and they have difficulties for basic living in the blind spot of our society. In particular, the heating is quite a serious issue for the senior citizens who live alone and belong to vulnerable social group in the winter, and to make it worse, they are exposed to frequent fire accidents due to the negligence in handling electric appliances such as electric heaters and electric pads. The main reason the indoor tent products are being used by senior citizens who live alone is that it saves energy, ensures warm sleep, and improves fire safety. Following the expansion of the indoor tent market, this study focused on the idea that there is a need for an in door tent suitable for senior citizens who live alone and belong to low income bracket and intended to improve its efficiency in relation to use, resting, and storage. For this, a basic survey was conducted on the products of existing brands to analyze advantages and disadvantages and it was possible to understand the demands that consumers have for existing products. Accordingly, a survey on consumer preference was conducted using a designed model and the Zabara typp, which demonstrated the best efficiency in terms of installation convenience, space usability, and appearance design was selected. Based on the results of selection, the product design and final prototype were completed. The results and details of the study are as follows; First, factors that were not recognized in product development phase could be identified through usability survey and interview with actual users. Second, for the effective aspect of the prototype, senior citizens could install and fold the tend more easily and quickly than expected. Based on these results of this study, it is expected that not only senior citizens who live alone but also various other users can use the tent to create another comfortable private space indoors.
