Seoul public bike program facilitates access to bicycles and offers potential for greater mobility and health for users. Furthermore, it would have positive impacts on transport congestion, energy use, and the environment. Hence, it is important to find future rental locations by taking to account both bike-demand and regional imbalance. This paper first finds eligible candidates of rental locations with the required spatial conditions such as a sufficient sidewalk width and accessibility of bike pick-up vehicles. And then, estimates public bike daily usage for each selected location via random forest based on Seoul public bike historical usage, Seoul geographical features, regional characteristics, and populations. This study contributes to a better comprehension of the Seoul public bike program, and would be useful in determining new public bike rental locations.

Smart TV is rapidly growing with the provision of OTT services, and has become an alternative to pay-TV services. Yet smart TV in Korea has been diffused slowly, and thus few research has paid attention to smart TV. With the global growth trend of smart TV, research on smartTV, focusing on users' characteristic and their behaviors, is critical to explain smart TV's usage. To employ the Mediapanel dataset, this study explores the impact of smart TV users' demographic factors and their pay-tv usage on smart TV usage. The results suggested that age, the type of household, household income, and market size are associated with smart TV usage. Pay-TV usage, specifically IPTV subscription and VOD expenses, have impacts on smart TV usage. Lastly the interaction effect between IPTV subscription and movie VOD expenses, has negatively associated with smart TV usage. This study may bring to re-attention to smart TV and to give insights into the industry field.

In recent years, many people are living in a space limited by rapid global industrial development and economic growth, and rapid urbanization is underway, with the global urban population estimated to be more than 70 percent in 2050. Due to rapid urbanization, government-led smart city models are being developed and introduced to solve various urban problems such as disaster safety, air pollution, water pollution, energy shortage, disease, crime and transportation. However, since ICT technology of public housing is being developed as a type of social overhead capital project, it is necessary to develop micro-smart city projects that residents can feel by developing services such as public safety, living environment, living welfare, and energy management for public housing residents. Therefore, in this paper, the smart platform model of public housing for smart city in the era of the Fourth Industrial Revolution is planned and presented.

Recently, shared dockless e-scooter usage has rapidly increased, rather than the station-based shared mobility service, because of convenience. This transition leads to new social problems in urban areas such as increased traffic accidents and hindrance of pedestrian environments. In this study, we analyze the usage characteristics of shared e-scooters in Seoul, and identify factors influencing demand for shared e-scooters by developing a negative binomial regression model. As a result, the usage characteristics show that the average trip distance, the average trip duration, and the average trip speed were 1.5km, 9.4min, and 10.3km/h, respectively. Demographic factor, transport facility factors, land use factors, and weather factors have statistically significant impacts on demand for shared e-scooters. The results of this study will be used as basic data for suggesting effective operation strategies for areas with higher shared e-scooter demand and for establishing transport policies for facilitating shared e-scooter usage.

Large-scale urban concentration of population and vehicles due to economic growth in Korea has been causing serious urban transport problems. Although the collection of congestion pricing has been evaluated as the most effective transportation policy to alleviate traffic demand, its effectiveness is very limited as it was just executed around congested points or along main arterial roads. This study derived dynamic congestion zones with the average travel speed of 206 traffic analysis zones in Busan Metropolitan City to propose a dynamic congestion pricing collection system by employing Space-Time Cube Analysis and Emerging Hot Spot Analysis. As a result, dynamic hot spots were formed from 7h to 24h and particularly, traffic congestion was severely deteriorated from 18h to 20h around Seomyeon and Gwangbok-dong. Therefore, it is expected that the effect of dynamic congestion pricing will be maximized in managing traffic demand in the city center.

저출산으로 경제활동인구가 감소했는데도 청년실업자가 늘어난 나라는 한국, 이탈리아, 그리스인데 이는 OECD국가 중 유일하다. OECD 청년고용률은 2009년 40.5%에서 2019년 43.5%로 증가했지만 순위는 30위에서 32위로 하락했다. 코로나19사태로 매출이 감소한 국내 301개사는 채용을 미루거나 포기한 비율이 전체 50.5%애 이르면서 앞으로 청년 취업 상황을 악화시킬 것으로 보인다. 양질의 일자리가 증가하면 이를 통해 개인은 경쟁력을 확보하게 되고 산업은 고급 인력을 바탕으로 성장구조를 만든다. 따라서 민간과 정부는 창업을 적극적으로 독려하고 활성화 시킬 필요가 있다. 청년창업대상자를 중심으로 진행하는 사업은 중소벤처기업부의 청소년 비즈쿨 사업과 창업에듀, K-스타트업, 청년창업사관학교, 학생창업유망팀 300등이 있다. 그러나 대부분의 지원 사업이 초기창업단계에 지원역량이 강화되어 있고 공급자 위주로 창업지원 사업을 운영하다보니 창업 성과는 미미하다. 통계청 자료에 의하면 20대는 생계유지에 대한 문제와 창업자금으로 인해 창업을 망설이고 30대는 가족을 돌보는 것에 대한 부담감과 기업가에 대한 부정적인 인식으로 창업을 기피 하는데 이는 40대이상 다른 연령층보다 높게 나타났다. 본 연구는 개인적, 환경적 요인이 연령에 따라 창업의지에 어떤 영향을 미치는지 비교분석하여 일자리 활성화를 위한 정부의 청년창업지원대책 기초자료에 도움이 되고자 한다. 청년창업대상자의 금전에 대한 태도, 창업역량, 성공한 롤모델, SNS 활용능력, 창업지원정책, 사회적지지, 인적네트워크, 해외시장 관심도가 창업의지에 어떤 상관 관계를 갖는지 비교연구를 진행하고자 한다. 10대의 경우 취업과 창업을 고민하는 특성화고등학생 150명, 20대 150명, 30대 150명으로 총 450명의 데이터를 가지고 SPSS 23을 통해 다중회귀분석을 진행하고 원인을 비교해 앞으로의 정책이 창업을 독려하고 지속력을 갖기 위한 방향으로 시사점을 제안한다.

The Investment to road projects has been a hot issue in the aspect of its possible overlapping or overinvestment in Korea. Therefore, additional road construction is not always accepted in these days. This paper investigated several indices including the country index and the road-extension rate index as well as a newly developed index for identifying and comparing road stocks among the OECD countries. Furthermore, the study has estimated some reasonable amount of additional road stocks of Korea when its GDP becomes twenty thousands per capita to forty thousands per capita in future by comparing the amount of stacks of OECD countries at those times. The result can be used for setting the target of road stocks in practical manner in the absence of the universally accepted theory in the road stock provision arena.

Regional migration is a problem faced by all non-metropolitan areas in Korea, but the extent of migration varies depending on regional economic conditions. This study examines how the extent of youth migration varies depending on the economic conditions of their birthplaces. The results showed that youth migration was more severe in areas suffering from population decline and aging problems. The smaller the economy and the weaker the financial independence of the region, the more severe the youth migration. In particular, commercial, educational, and cultural facilities, except for medical facilities, were not able to curb youth migration. In addition, there was a significant wage gap between those employed in the metropolitan area and those employed in the regions, regardless of their origin. This suggests that non-metropolitan areas are caught in a vicious cycle of regional economic deterioration and youth migration.

The aim of this study is to conduct a comparative study on the sustainability of the public pension. While the mainstream view on the sustainability of the public pension presupposes financial sustainability, the original purpose of guaranteeing retirement income has been overlooked. The sustainability of the public pension needs to consider not only financial sustainability, but also various factors such as demographic structure, labor productivity, industrial structure, life cycle of working households, government spending on public pensions, economic growth, and social consensus. With this awareness of the problem, this study conducted a fuzzy set qualitative comparative study in 44 countries, including Korea. As a result of the analysis, it was found that Korea had high financial sustainability for a single year, but relatively low integration related to social consultation and public pension operation, and adequacy such as the degree of guarantee and linkage with other pension systems was also relatively low. The sustainability of the broader public pension should be emphasized not only for financial sustainability, but also for adequacy and integration.
