Because people are gradually interested in bicycles, central and local governments provide many efforts for expanding bikeway plans and utilization. However, most domestic bicycle plans have been established for the urban and leisure. This research is focused on developing the evaluation method to give the priority order for the investment of rural community bicycle roads. For the methodology development, the planning hierarchy and indicator framework are proposed in this paper. In order to decide the weighting value for indicators, a questionnaire survey to transportation experts was conducted. Moreover, the coefficient for social and spatial equity was applied to consider the balance of regional development. The evaluation was applied to a pilot corridor comprised of a 160km section of national highway in korea. This methodology provides a new tool to decide priority order for the investment of bicycle facilities.

The vulnerability analysis of climate change driven disaster has been used as institutional framework for the urban policies of disaster prevention since 2012. However, some problems have occurred due to the structure of vulnerability analysis, such as overweighted variables and duplicated application of variables of similar meaning. The goal of this study is to examine the differences of results between the method of current guideline and the method of weight equalization. For this, we examines the current structural framework of the vulnerability analysis, and performs empirical analysis. As a result, the extent and magnitude of vulnerability showed different spatial patterns depending on the weighting methods. Standardized weighting method relatively represented wider vulnerable areas compared to the pre-existing method which follows the current instruction manual. To apply the results of vulnerability analysis to urban planning process for disaster prevention, this study suggests that the reliability of the results should be ensured by improving analytical framework and detailed review of the results.

Recently, as part of the crime prevention measures that focus on spatial characteristics on the determinants of crime-causing, interest in crime prevention (CPTED) through environmental design has been increasing. This study analyzed crime vulnerabilities in Ulju-gun for the purpose of establishing a master plan for crime prevention urban design (CPTED). The 12 indicators, including demographic, socioeconomic, and physical factors, were sampled from prior studies. As a next step, statistical analysis resulted in criminal vulnerability indexes. According to the analysis, districts with a high demographic crime vulnerability indexes were concentrated on apartment complexes, while districts with high socio-economic crime vulnerability indexes have low land prices and high proportion of female population. Also, the districts with high physical crime vulnerability indexes were found to be heavily distributed commercial ones with a large number of entertainment places. However, there was a limit to generalizing the indicators of previous studies to local governments with different regional characteristics. Therefore, further studies should be carried out by establishing additional indicators considering regional characteristics in the future.

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.

정부는 지구온난화로 인해 기후변화에 대응하고 세계적 경제위기를 극복하기 위해, 저탄소녹색성장기본법(2010년 1월)을 제정하여 저탄소 녹색성장을 추진하고 있다. 저탄소 녹색성장은 신재생에너지, 탄소배출권 거래제도, 5+2 광역권개발정책, 저탄소 녹색도시 등으로 요약할 수 있다. 본 연구의 목적은 저탄소 녹색도시계획 및 이에 대한 전략환경평가의 동향을 고찰하고, 저탄소 녹색도시계획에 대한 전략환경평가의 방향을 제시하는 데 있다. 저탄소 녹색도시 조성 관련 연구를 고찰한 후, 환경부의 사전환경성검토 업무매뉴얼의 도시계획의 환경성제고 방안과 국토해양부의 전략환경평가 업무처리규정, 도시계획수립지침, 저탄소 녹색도시 조성을 위한 도시계획수립지침(2009), 저탄소 녹색도시계획 표준모델(2010), 녹색도시개발계획 등을 포함하면서 개정된 도시개발업무지침(2011)이 도시계획에 제대로 반영되는지를 검토하고, 외국의 기후변화에 대응하는 전략환경평가를 고찰한 결과는 다음과 같다. 첫째, 기후변화 대응 도시계획의 내용은 저감방안과 적응방안 두 가지로 나눌 수 있는 데, 저감방안은 경제적 및 기술적으로 한계가 있으므로, 향후 전략환경평가는 저감방안과 함께 적응방안을 강조할 필요가 있다. 둘째, 기후변화 대응(저감과 적응)을 위해 전략환경평가의 목표와 지표를 설정한다. 셋째, 국토해양부의 상위계획(광역도시계획과 도시기본계획)에 대한 전략환경평가와 환경부의 하위계획(도시관리계획)에 대한 전략환경평가의 긴밀한 연계가 필수적이다. 넷째, 전략환경평가는 도시기본계획 수립 후에 이뤄지는 독립된 과정이라기보다는 도시기본계획 수립과정에서 중요한 부분으로 인식하는 것이 중요하다. 장기적으로는 도시기본계획과 도시환경계획을 연계시키는 것이 바람직하다.

As a follow up to the Agenda 21's policy statement for safe management of radioactive waste adopted at Rio Conference held in 1992, the UN invited the LAEA to develop and implement indicators of sustainable development for the management of radioactive waste. The IAEA finalized the indicators in 2002, and is planning to calculate the member states' values of indicators in connection with operation of its Net-Enabled Waste Management Database system. In this paper, the basis for introducing the indicators into the radioactive waste management was analyzed, and calculation methodology and standard assessment procedure were simply depicted. In addition, a series of innate limitations in calculation and comparison of the indicators was analyzed. According to the proposed standard procedure, the indicators for a few major countries including Korea were calculated and compared, by use of each country's radioactive waste management framework and its practices. In addition, a series of measures increasing the values of the indicators was derived so as to enhance the sustainability of domestic radioactive waste management program.

The purpose of this study is to provide implications for fiscal policy by comprehensively examining the relationship between the on-campus retention and university soundness items of four-year private universities in the context of financial contraction of private universities due to suppression of tuition increase. Multiple regression analysis was performed to analyze the correlation of variables and the effect of financial soundness items on accounting indicators using SPSS 25. First, private university's on-campus reservations had an effect on accounting index items. Second, financial soundness items had an effect on accounting index items. Third, the financial condition factors influenced the change of accounting index by the location of the university. Fourth, according to the size of students, financial conditions had an effect on the change in accounting indicators. Government investment and support for private universities should be changed to a paradigm of securing finance through establishment of a development plan, rather than financial support through reduction of quota, and survival should be sought through income diversification policy strategies.

홍수(floods)는 인간의 생명과 재산에 큰 피해를 발생시키는 자연재해 중 하나로 최근 지구 온난화와 기후 변화로 인하여 홍수 발생 빈도와 강도가 증가하고 있다. 때문에, 홍수 발생 시 정확한 홍수량 산정을 위하여 유역 내 지표수 및 지하수 흐름 분석을 통하여 전반적인 물 순환의 이해가 필수적이다. 이에 본 연구는 지표수-지하수 연계 모형을 활용하여 홍수 발생 시 미호천 유역에서 지하수가 하천 유량에 미치는 영향을 분석한다. 본 연구는 Hydrological-Ecological Integrated watershed-scale Flow (HEIFLOW) 모형을 적용하여, 국내 유역 특성을 고려하여 시간단위 홍수 사상 분석을 수행한다. 모형 구축을 위하여 2013년과 2014년도의 미호천내의 7개 기상 및 강우관측소, 1개의 수위 관측소의 정보를 활용하여 지표수 모형을 구축하며, 같은 기간의 지하수 모형 구축을 위해 7개의 국가 지하수 관측망의 지하수 수위 자료와 유역의 수문지질도(Hydrogeological map)의 정보를 활용한다. 미호천 유역 내 HEIFLOW 모형의 홍수 모의 결과 산정된 하천 유량은 관측 유량과 0.79 R²의 우수한 모의 성능을 나타내고 있으며, 지하 수위 모의 역시 지하수 수위 변동을 적절하게 모의한다. 또한, 미호천 유역의 하류 지역은 하천으로 유출되는 지하수가 하천의 기저 유량에 상당한 영향을 미치는 것으로 나타나며 홍수 시에는 지하수 유출의 증가로 인한 급격한 첨두 홍수량의 상승을 보인다. 이와 같은 결과는 홍수 모의 시 지표면 유출 분석에 초점을 두고 있는 홍수 국내의 홍수량 산정 방법에 지하수의 거동 및 하천 유량에 미치는 영향을 정량적인 정보를 제공할 수 있을 것으로 판단되며, 추후 국내 홍수량 산정의 새로운 방법의 하나로 활용될 가능성을 보여준다.
