Purpose: This study extends previous empirical work on the threshold effects of institutions on the relationship between infrastructure and economic growth. It does so by using three sub-indices of institutions as the threshold variable in place of aggregate index. This is with a view to determining the roles of the sub-indices in the nexus between infrastructure and economic growth. Research design, data and methodology: The analysis is based on a dynamic panel threshold regression model using a panel data set comprising 41 countries in Sub-Saharan Africa over the sample period of 1996-2015. Data are obtained from Ogbaro (2019). Results: The study finds that infrastructure exerts significant positive effects on economic growth below and above the threshold values of the three sub-indices, with higher effects above the threshold values. Results also show that on average, the Sub-Saharan African countries are not able to satisfy any of the threshold conditions, which accounts for their poor growth experience. Conclusion: The study concludes that countries with weak institutions do not benefit maximally from infrastructure development policies. The paper, therefore, recommends that countries in Sub-Saharan Africa need to focus on improving their institutional patterns if they are to reap the optimum benefits from their infrastructure development efforts.

본 연구에서는 지구단위 내 교통부문에서 다양한 도시설계 및 교통정책의 적용에 따른 $CO_2$의 배출량 효과를 분석해보고자 하였다. 이를 위해 가상네트워크(Toy Network)를 설정하고 토지이용패턴과 교통정책을 접목한 19개의 시나리오를 가정한 후 교통수요 예측 프로그램인 EMME3를 이용하여 $CO_2$ 발생량을 산정하고 비교하였다. 그 결과 총 $CO_2$ 배출량이 가장 많이 감소한 정책은 지구의 중간부를 개발하면서 동시에 내부의 2차로 도로는 차량 통행을 금지시키고 보행자 천국을 만드는 것이었다. 총 $CO_2$량이 가장 많이 발생된 그룹은 교통공학에서 일반적으로 인식되어 왔던 적절한 도로위계에 따른 도로망 구성 및 접근통제 조절 정책이었다. 따라서 지구설계시 도로망 구성 및 접근통제는 세밀한 연구를 통해 실행되어야 할 것임을 알게 되었다.

국내외 도서관에서는 3D 프린터와 관련 서비스 도입을 확대하고 있다. 이에 따라 각 도서관은 원활한 서비스 운영을 위해 3D 프린터 이용정책을 수립할 필요가 있다. 본 연구에서는 국내 도서관의 3D 프린터 이용정책 보유 여부와 내용을 확인하고, 미국 도서관의 우수한 3D 프린터 이용정책 사례의 내용을 분석하여 국내 도서관을 위한 3D 프린터 이용정책 내용을 제안하였다. 연구 결과, 국내의 3D 프린터 보유 도서관은 성문화된 이용정책을 보유한 곳이 거의 없었다. 따라서 미국 소재 16개 도서관(공공 10개관 및 대학 6개관)의 3D 프린터 이용정책 우수사례를 내용 분석하여, 이를 바탕으로 다섯 개의 상위주제(목적, 이용자, 이용방법, 이용제한, 도서관 면책)와 21개의 하위주제를 도출하였다. 본 연구결과는 3D 프린터 이용정책 수립을 위한 기초자료로 활용될 수 있을 것이며, 나아가 3D 프린터를 활용한 이용자 서비스를 위한 고려사항을 제시하는데 의의가 있다.

이 연구는 윤석열정부의 복지정책을 정책적 및 이론적 측면에서 분석한다. 이론적 측면에서 이 연구는 윤석열정부가 이전 정부와는 확연히 다른 복지제도 모델을 구축하고 실행하고자 했음을 보여준다. 새 정부는 한국 보수 정당의 복지이념인 자생복지에 바탕을 둔 약자복지모델을 제시하였다. 윤석렬정부가 직전 문재인정부의 정책을 계승한 것은 취약계층을 위한 복지 확대와 가족지원의 확대 분야에 국한되었고, 나머지 정책에서 이전 정부와 뚜렷이 다른 방향을 추구하였다. 정책적으로 이 연구는 윤석열정부의 복지정책이 한국 복지체제에 광범위하게 걸쳐있는 복지 사각지대 문제를 해결하기에 불충분하다는 것을 보여준다. 윤석렬정부의 정책에서 복지 사각지대 해소에 기여할 수 있는 정책은 기초보장 개선, 부모수당 도입, 상병수당 도입 추진과 같이 소수의 분야에 제한된다.

국제해사기구의 해양환경보호위원회에서 CO₂ 배출량 감축의 지구적 노력에 동참하기 위해 최근 선박에서 대기로 방출하는 CO₂의 양을 지수화 하고자 하는 논의가 활발히 진행중이다. 그 대표적인 지수로서 신조선 설계 건조시에 적용하는 에너지 효율지수(EEDI : Energy Efficiency Design Index for new ships)와 현재 또는 건조 후 항행시에 운항선에 적용되는 에너지 효율지표(EEOI : Energy Efficiency Operational Indicator), 그리고 운항선의 에너지 효율관리 계획(SEEMP : Ship Energy Efficiency Management Plan)등이다. 본 지수는 선박을 설계 건조시부터 각 선박당 CO₂의 배출값을 산정하고 운항시에도 CO₂배출을 개량하고 이를 감축하는 방안을 모색하도록 유도하는 조치가 될 것이다. 향후 3년내에 발효될 수 있는 임박한 CO₂선박 배출 규제를 조사 분석하고 향후 발전방향을 모색해 보고자 한다.

This study aims to investigate the relationship between urbanization, economic growth, energy consumption, and CO2 emissions in Indonesia. The data used in the study are time-series data for the period 1985-2017; the data utilized are sourced from World Development Indicators obtained on the World Bank database. The method uses a quantitative approach that applies the vector error correction model based on the Granger causality test. The empirical results reveal that, in the short run, there is evidence that urbanization and energy consumption can causes CO2 emissions, and they also prove that urbanization can cause energy consumption. Also, other findings prove the existence of long-run relationships flowing from energy consumption, economic growth, and CO2 emissions toward urbanization, as well as the existence of the relationship flowing from urbanization, economic growth, and CO2 emissions towards energy consumption. The results of testing the relationship between economic growth and CO2 emissions reveal that the environmental Kuznets curve hypothesis is proven in Indonesia. Thus, policies are needed to limit the impact of urbanization through high awareness-raising to maintain environmental quality and greater use of energy. Also, energy conservation policies are needed in all sectors, especially the electricity, industry, and transportation sectors.

The issue of the relationship between environmental degradation and human health has been widely addressed by medical doctors. However, economists have sparsely debated it. The release of carbon dioxide (CO2) into the air can cause several environmental problems and, thus, it can affect human health. Therefore, it is imperative to examine the effect of CO2 emissions on life expectancy in the D-8 countries (Malaysia, Indonesia, Bangladesh, Nigeria, Egypt, Iran, Pakistan, and Turkey) from 1992 to 2017. The panel ARDL method is employed and, then, the PMG estimator is selected. The results show that economic growth, population growth and health expenditure can significantly and positively affect life expectancy, but CO2 emissions can have a significant and negative effect on life expectancy. Since, the major findings reveal that life expectancy can be explained by CO2 emissions. Hence, it is important to formulate policies on reducing CO2 emissions so that life expectancy will not be affected. Energy diversification policies should be formulated or improved in some countries. This is to ensure that the countries are not highly dependent on non-renewable energy that can harm the environment. The government should increase its expenditure on the health sector to save more lives by extend human lifespan.

Land utilisation for various production practices in rural communities in Nigeria is marked with copious challenges and the management has become unsustainable among the local population. Therefore, the study was conducted to analyse factors influencing land use typologies, LUT among farming households in Akinyele Municipality of Oyo State, Nigeria. The employed a 3-stage sampling procedure for selection of 50 respondents from the study area. Information on demographic characteristics of the respondents, typologies of land use and factors impacting was collected with a structured questionnaire. The analyses of data collected was carried out was with frequencies, percentages and logit regression. The study showed majority (78.0%) were male, aged between 40 and 49 years, married (86.0%) and had secondary education (56.0%). The majority (78.0%) had household size ranging from 4-6 members, engaged in farming (80.0%). Furthermore, the result revealed that 94.0% of respondents conserve existing trees on their farmland, and about 56.0% of them were practicing agroforestry. The major factors affecting land use typologies were outcomes of climate change. The determining factors influencing LUT among farming households were occupation (β=1.829^*), irregular rainfall (β=1.436^*), depleted fruiting (β=1.438^*), poor weather condition/drought (β=1.020^*), and farmers' indigene (β=3.247^*) at α_0.05. The study recommends strengthening of land management policies and stakeholders' engagement in decision making as regards policies actualization to make land use typologies noticeable, effective and pronounce among farming households.

The transition toward clean energy is an issue of great importance with growing debate in climate change mitigation. The complex nature of nuclear energy-CO₂ emissions nexus makes it difficult to predict whether or not nuclear acts as a clean energy source. Hence, we examined the relationship between nuclear energy consumption and CO₂ emissions in the context of the IPAT and Environmental Kuznets Curve (EKC) framework. Dynamic Auto-regressive Distributive Lag (DARDL), a newly modified econometric tool, is employed for estimation of long- and short-run dynamics by using yearly data spanning from 1971 to 2018. The empirical findings of the study revealed an instantaneous increase in nuclear energy reduces environmental pollution, which highlights that more nuclear energy power in the Indian energy system would be beneficial for climate change mitigation. The results further demonstrate that the overarching effect of population density in the IPAT equation stimulates carbon emissions. Finally, nuclear energy and population density contribute to form the EKC curve. To achieving a cleaner environment, results point out governmental policies toward the transition of nuclear energy that favours environmental sustainability.
