This paper attempts to compare and analyze the intensity, trend, and regional gap of income inequality, capitalizing upon the Age-Period-Cohort model which considers age, time and cohort effects, with the 1998-2018 Korea Labor Panel (KLIPS) survey data for respondents living in the Capital and Non-Capital Regions. The main analysis results are as follows. First, in the case of both cohort and age effects, those in their 50~60s, including the so-called baby boomers and '386 generation' living in the Capital Region, have relatively lower income inequality effect compared to that of other age groups and cohorts in the Non-Capital Region. Second, the micro-individual characteristics cannot be ignored to account for a regional gap in income inequality, but rather the effects of structural and institutional omitted variables and the social discrimination effects of individual characteristics variables are more significant in explaining it. Overall, intra-and inter-cohort income inequalities appear to overlap.

This study aimed to assess trends in the prevalence, treatment, and control of diabetes according to the socio-economic level in Korean adults aged ${\geq}30$ years, using the 2007-2017 Korea National Health and Nutrition Examination Survey data. Socio-economic status was assessed based on the household income. Multivariable logistic regression and predictive margins were used to evaluate the adjusted proportion of diabetes prevalence, awareness, treatment, and adequate glycemic control. During 2007-2017, the socio-economic inequalities on diabetes prevalence were observed in both men and women. However, the gradient of inequality increased only in men (p for interaction=0.034). Diabetes awareness, treatment, and control did not show socio-economic inequalities or increasing gradients in both sexes. Monitoring of these trends should be continued, and further research on effective interventions is needed.

우리 국민의 교통수요행태를 분석하기 위하여 준이상수요체계(almost ideal demand system) 함수형태의 집계교통수요모형을 설정하였다. 대중교통수단으로서 시내버스, 시외버스, 택시, 기차, 전철이 그리고 개인교통수단으로서 연료비가 포함되었으며, 기타재화 및 서비스에 대한 소비지출이 함께 추정되었다. 추정에 이용된 자료는 통계청의 "도시가계연보"에 수록된 '전국 도시가구 소비지출'과 "물가통계"에 수록된 '전국 도시소비자 물가'이다. 추정결과 모형의 설명력을 나타내는 수정결정계수(adjusted-$R^2$)는 대부분 0.9 내외에서 높게 나타났다. 추정계수는 총 51개중에서 25개가 5% 수준에서 유의한 것으로 나타났다. 추정된 계수값을 이용하여 가격탄력성과 소득탄력성을 구하였다. 자기가격탄력성과 소득탄력성 추정치는 조금 높기는 하나 부호와 상대적 크기가 모두 예상과 일치하고 다른 연구결과들과 유사한 범위에 있다. 연료비에 대한 소득탄력성은 1.72로 가장 높게 나타났고, 대중교통수단은 0.03~0.49 사이에서 나타나므로 교통수단이 정상재임을 의미한다. 보상수요의 교차가격탄력성은 총 15개의 교차관계에서 12개의 관계가 상식과 일치한다. 다음 연구에서는 더 많은 시계열자료를 발굴하여, 장기간의 교통수요 변화에 대한 분석을 시도할 필요가 있다. 또한 초월대수함수나 동태함수 등 다양한 형태의 수요함수를 시도할 필요가 있다. 여러가지 형태의 교통수요함수추정을 통해서 우리 현실에 적합한 교통수요모형을 발견할 수 있을 것이다. 대도시와 중소도시 등 지역별 지출자료를 발굴하여 지역특성을 반영하는 교통수요함수의 추정도 필요하다.

Changes in the public welfare attitudes are very important to the welfare politics and policy. Considering that variability of public welfare attitudes has been ignored in previous studies, we analyzed welfare attitudes changes at individual level in Korea. Using the longitudinal data from the Additional Survey of 2010/2013/2016 Korea Welfare Panel Survey, we analyzed the changes in public welfare attitudes during 2010th-2016th years. Major findings are as follows. First, one of the findings from analysis is that the public welfare attitudes are very active and dynamic in Korea. This finding is contradiction to the results of the previous researches that are point to the stability or inertia of the public welfare attitudes in western welfare states and also in Korea. Second, occurrences of the welfare attitudes change are related with various individual characteristics; income status, occupation status, age, region, sex, political ideology, etc. These results from this study on the welfare attitudes change suggest that dynamics of the Korea welfare politics in recent years reflected the dynamic changes in public welfare attitudes. And, they suggest that Korea welfare politics are transformed from the traditional classes welfare politics to the new welfare politics which are influenced by various interests of the socio-demographic groups.

본 논문에서는 사진의 태그정보 및 통계정보, 사용자 평점을 이용하여 여행에 앞서 본인의 취향 등에 맞는 개인화 된 여행계획을 생성할 수 있도록 지원하는 연구를 진행하였다. 개인화 된 여행계획의 자동생성을 위하여, 나이, 성별, 직업, 소득, 학력에 따라 선호하는 여행의 태마를 통계자료를 통해 구분하였고, 사진의 태그정보를 이용하여 사용자가 가장 선호하는 테마를 분별하여 개인화 할 수 있도록 하였다. 이렇게 구분된 태마는 다양한 포털사이트에 등록된 사용자 평점 정보를 토대로 하여 여행계획을 생성하여 사용자에게 제공할 수 있도록 하였다.

통신기술의 발전이 가져온 스마트 시대로의 진입은 다양한 스마트 디바이스와 콘텐츠 및 문화를 보급, 창출해내며 우리 사회 전반적인 라이프 스타일의 변화를 선도하고 있다. 특히 국민소득의 증대로 건강에 관한 소비자 욕구가 증대하면서 더 나은 삶의 질을 추구하는 웰니스가 급부상함에 따라, 치료 중심이 아닌 예방과 케어, 힐링을 위한 다양한 서비스를 위한 디바이스와 플랫폼, 분석기술의 개발 및 적용이 요구되고 있다. 또한 단순히 서비스를 제공받던 수동적인 과거 소비자 형태가 스마트 디바이스를 적극적으로 활용해내는 능동적 소비자의 모습으로 변화함에 따라 이러한 움직임은 앞으로 단순히 서비스 제공의 측면이 아닌, 웰니스 증진을 위해 특화된 스마트 디바이스와 컴퓨터, 소비자와의 상호작용에 기반한 기술로 발전되어갈 전망이다. 본 논문에서는 건강은 물론 개인의 라이프 스타일을 포함한 라이프로그 기반의 다차원적인 정보 수집과 체계적 분석, 그를 통한 모니터링과 맞춤형 서비스를 실현하는 개인화웰니스기록을 활용한 개인맞춤형웰니스 관리 시스템을 설계하고자 한다.

This study is a study on the change of life and leisure satisfaction caused by the reduction of working hours of office workers, summarizing the results of the analysis as follows: First, the change in the working hours of office workers was found to be men (42.4 percent), but women (54.7 percent) had a high increase in personal satisfaction, monthly income of 2 to 3 million won 96.1 percent, and personal satisfaction increased in small and medium-sized cities and towns. Second, leisure satisfaction due to shorter working hours was somewhat high in monthly income of 3 million won to 4 million won (43.6%) and more than 6 million won (39.1%), but there was no change in leisure satisfaction by gender, age, academic background, number of family members, marital status, worker status and region. The revitalization of leisure is a very important task in personal life, but it is meaningful in that it provided implications for socializing leisure as leisure satisfaction is positively spreading in life changes.

There has been active discussions on informational view among various privacy perspectives because of Internet usage. Social science research has largely discussed determinants of information privacy concerns (IPC) and its behavioral outcomes. However, the focus of studies was limited to company's practices and existing studies have not reported consistent results. In addition, the relationship between demographic characteristics of user and IPC has not been discussed enough. In this study, we re-investigate the relationship between users' demographic characteristics and IPC with data from a large sample provided by the Korea Information Society Development Institute (KISDI). The results showed that educational background and income level have effects on IPC in line with existing studies. But the effects of gender and age had different impact on IPC compared to previous studies. This study has implications in enabling generalization of empirical findings and confirming the results of previous studies.

필자는 국가 간 국민소득의 차이는 국민 개개인의 자질보다도 그 국가가 보유하고 있는 제도의 품질 차에서 비롯된다고 믿고 있다. 그러므로 이러한 제도들은 정부가 생산하여 국민에게 공급하여야 하는 공공재이고 눈에 보이는 도로, 항만보다도 훨씬 더 중요한 사회간접자본이다. 그래서 지금쯤이면 25년 이전의 공정거래법의 골격을 지금의 발전된 우리 국가와 경제의 수준에 맞추어서 전반적으로 한 단계 업그레이드 할 것을 진지하게 검토할 때가 되었다고 생각하는 것이다.

Since the introduction of the Riester Pension Scheme, the controversy has continued in the policy studies and the political debates. This study evaluates the achievements and limitations of the German Riester pension scheme and tries to derive policy implications for South Korea. As a result of the analysis, the most worthwhile achievement of the Riester Pension is to strengthen the role of the private pension schemes. Unlike other private pension schemes, it included a large part of lower income households. It also opened a new perspective of utilizing private pension schemes to accomplish the goals of the family policy. Despite these attainments, it does not reach the promised coverage rate. It also was revealed that the higher income households have concluded more Riester Pension Contracts than the targeted lower-income households. Due to high administration fee and incomplete information problems, benefit levels are supposed to be much lower than expected. It concludes, above all, despite some achievements, the Riester Pension Scheme will not fill completely the gap of old age income security caused by the reduction of the public pension system. The German case provides fruitful lessons for Korea. The introduction of a subsidized personal pension scheme in South Korea can be realized only when some prerequisites would be satisfied such as the consolidation and maturing of public pension schemes and the strengthening of the transparency in the private pension market.
