In this paper, we proposed a method using sub-edge information extracted through a hierarchical structure in the process of generating super resolution based on a single image. In order to improve the quality of super resolution, it is necessary to clearly distinguish the shape of each area while clearly expressing the boundary area in the image. The proposed method assists edge information of the image in deep learning based super resolution method to create an improved super resolution result while maintaining the structural shape of the boundary region, which is an important factor determining the quality in the super resolution process. In addition to the group convolution structure for performing deep learning based super resolution, a separate hierarchical edge accumulation extraction process based on high-frequency band information for sub-edge extraction is proposed, and a method of using it as an auxiliary feature is proposed. Experimental results showed about 1% performance improvement in PSNR and SSIM compared to the existing super resolution.

사회복지 분야는 정부가 개입해야 하는 대표적인 정책영역이나, 공공성을 강조하면서, 시장기능을 전혀 고려하지 않는 정부개입은 정부실패라는 왜곡을 발생시킨다. 사회복지 서비스는 공공재라기 보다는 가치재로서, 사유재 성격을 가지므로 정부와 시장역할에 대한 균형된 시각이 필요하다. 시장실패와 함께 정부실패라는 경제적 왜곡현상을 동시에 고려하면서, 정부와 시장의 최적역할분담이 이루어져야 한다. 보육정책의 방향은 공공성이 높으므로, 정부가 주도가 되어 모든 국민들에게 똑같은 보육서비스를 공급하는 것이다. 획일적인 보육서비스 질을 정부재원의 확대로서 높이려는 정책방향은 필연적으로 정부실패라는 왜곡을 발생시킨다. 현재 많은 전문가들이 지적하는 민간부문의 보육서비스 질이 낮은 근본원인은 시장규제에 있다. 즉 영리법인의 시장진입을 금지하고, 가격을 규제하고 있기 때문이다. 따라서 보육서비스 질을 높이기 위해서는 보육시장의 정부규제를 철폐해야 한다. 보육시장에 대한 규제 철폐없이 모든 국민들을 대상으로 한 보육재정의 확대는 재정의 낭비를 초래하게 된다. 보육정책의 바람직한 방향은 정부와 시장의 역할분담을 통해서이다. 보육서비스의 외부 불경제 효과가 높은 만큼, 시장에서 충족시키지 못하는 일정소득 이하 계층에 대한 보육서비스는 정부에서 무상으로 제공해야 한다. 그러나 일정소득 수준이상의 계층에게는 다양한 수요가 시장기능에 의해 해결될 수 있도록 해야 한다. 시장실패의 논리와 함께 정부실패라는 왜곡의 심각성을 인식하고, 정부와 시장기능에 대한 최적의 역할분담이 이루어져야 한다.

This study investigates what influences the 2030 households' intention to utilize housing support policies for the younger generation. Using the logistic regression model, our empirical results show that the 'the recognition of youth housing support projects', 'the housing occupation', 'employment type', 'housing type', and 'age' factors have a significant effect on the intention to use the housing support policies. Specifically, the intention is positively associated with economic activity, one-room residence, monthly rent, employment status during the Covid-19 period, and policy recognition, while negatively related to age. In addition, willingness to use the housing support policies is greater when respondents lived in a studio, lived on a monthly rent, recognized the policy, and improved their employment status. The results suggest that housing support programs need to be expanded and improved. Moreover, information on housing support policies should be efficiently delivered to eligible households, and more sophisticated housing support policies should be provided for young people early in their careers.

This study analyzed the policy of culture welfare in libraries for the information alienated groups. This study suggested several improvements as a conclusion. Research analyzed organizational tasks and policies for Ministry of Culture, Sports and Tourism, Planning Group for Library and Information Policy and the policies for libraries. First, library service for alienated class was centered in short term period projects. Second, it is hardware oriented such as building small libraries, places for disabled person, multi-cultural libraries. Due to the decentralization of policies for the groups with alienated information, and lack of public supportive policies for private library for the disabled, developing cooperative system is difficult. Third, we revealed that policies for quantitative production of alternative material were achieved. So, this study suggested professional policy in integrative cooperation in accordance with each domain and creation of a separate welfare library policy department and its activity.

The aim of this study is to explore key strategy areas for academic library development planning in Korea. This study started with components of an academic library development plan that were identified in a literature review; those components included among others the major roles, functions, resources, and teaching and research support services of academic libraries. Upon interviewing library staff from 14 academic libraries, this study initially categorized those components into 4 overarching strategy areas and further subdivided them into 12 key components and 24 sub-components. That initial categorization was then reviewed by 6 scholars and practitioners, applying the analytic hierarchy process (AHP), by which this study analyzed the level of importance and priority of the strategy areas and various components. Based on the results, this study ultimately outlines 11 key components and 23 sub-components under the 4 strategy areas for academic libraries in Korea to take into consideration in their development planning.

This study will propose the policy priorities of cyber information security by AHP(Analytic Hierarchy Process) survey. The policy categories for AHP survey consist in the foundation of information security and activity of information security(1st hierarchy). In the second hierarchy, the foundation of information security was classified into laws-system, human resources, h/w-s/w technology and sociocultural awareness. And the activity of information security was divided into infrastructure protection, privacy protection, related industry promotion, and national security. Information policy alternatives were composed of 16 categories in the third hierarchy. According to the AHP result, in the perspective of policy importance, the modification of related laws was the first agenda in the policy priority, better treatment of professionals was the second, and the re-establishment of policy system was the third. In the perspective of policy urgency, the re-establishment of policy system was the first item, the modification of related laws was the second, and better treatment of professionals is the third.

There have been a growing number of studies that show huge discrepancies between individuals' perceptions of relative economic position and the economic position based on the reported income in the survey. If this is the case, it is expected that the impact of perceived income status on individual happiness can be different from that of objective income status based on the reported income. The aim of this study is to investigate the factors affecting the discrepancies between perception and reality with respect to relative income status, focusing on the 'Reference group theory'. This study also tries to extend existing knowledge of the relative status on the happiness level of individuals, by examining how individual's happiness can be changed by providing the accurate information about their objective income level. There are systematic biases in perceived income status. A majority of people who actually rank in the lower part of income ladder place themselves in higher positions, while a significant portion of rich individuals underestimate their actual income status. Secondly, the misperception about the income distribution is affected by a variety of individual, household characteristics and reference group income. Thirdly, providing individuals with accurate information has a considerable effect on their happiness level.

In the context of welfare politics, this study tries to examine how interest groups'policy priorities in the child-care policy of Korea were shaped and changed. Based on the already institutionalized child-care services, each beneficiary group-parents, employer and employee of child care center-has its own preference and perception in child-care policy. Futhermore, this difference has produced conflict of interests in the priority of policy options and brought interest group politics to the realm of child-care policy. With regard to interest group politics, this study firstly examines divergence of beneficiary groups'perception about the child-care policy priorities. Meanwhile, discourse politics should be regarded as another dimension of welfare politics because beneficiaries'perception preference in policy could be sometimes changed and converged by communicative policy discourse. By examining convergent aspects of beneficiary groups'perception about policy priority, this study secondly tries to analyze the discourse politics which has been influenced by the free child-care discourse during 2010-12 election period. To investigate these two dimensions of child-care politics, beneficiary groups'policy priority should be systematically and comprehensively classified and quantified. Using Analysis Hierarchy Process(AHP), this study identifies 11 policy issues and determines different ranking priorities of each beneficiary group.

This study analyzes the unequal distributional effect of threesome of family policy(child benefit, childcare services and parental leave) focusing on family income, mother's status in labor market in Korea. To measure the unequal distributional effect of family policies, this study used the quantile analysis. The results of this study are as follows. First, in terms of childcare service and parental leave, there is some difference of the rate of use by family income and mother's status in labor market. Second, total public fund for childcare services, child benefits and parental leave are high in fourth income quintile, and mothers work regularly. Third, public fund is high in fourth income quintile, dual earners, mothers work regularly, the family has many number of child, and is high educational level of parents. Finally, the results of quantile regression show the biggest factors of unequal distribution of family policy are mother's stable work and it deepens the inequalities and differences. Based on these results, this article suggests that more equal right to access and use family policy regardless of the type of employment, adequate minimum income through income transfer, and universal application of the policy.

This study aims to investigate unmet healthcare needs due to economic or non-economic difficulties among the elderly aged 65 or older. Using Korea Health Panel Survey (KHPS) data from 2018, the elderly are classified into one of four groups (health insurance subscribers, non-take-up, lower income relief, and medical aid recipients) based on their level of medical vulnerability. For hospital or dental care, the prevalence rates of unmet healthcare needs due to economic and non-economic difficulties are 12.6% and 10.6%, respectively. The prevalence rate of unmet healthcare needs due to economic difficulty in the medically vulnerable group was much higher than that of the non-vulnerable group-that is, health insurance subscribers. After controlling for other influential factors, medical vulnerability has a great impact on the prevalence rates of unmet healthcare needs due to economic difficulties. Compared to health insurance subscribers, the non-take-up, the lower relief, and the medical aid recipients are 1.4 times, 3.3 times, and 2.4 times more likely to experience unmet healthcare needs due to economic difficulty, respectively. The results of this study can provide important policy implications for securing essential healthcare resources for the elderly.
