In this study, in order to derive the priority of indicators and sustainability areas of smart ports, which means ports in the digital era, previous studies and ESG, which have recently been indispensably introduced in all industries worldwide, were studied together. A hierarchical structure was established with upper evaluation items and 20 lower evaluation items in four areas (operational, environmental, social, and governance), and a relative evaluation method of weighting items among the AHP techniques was applied. The pairwise comparison questionnaire consisted of a 9-point scale proposed by Satty (1980). A survey was conducted targeting working-level workers who perform sustainability or ESG(Environmental, Social, Governance)-related work at four representative port authorities in Korea (Busan, Incheon, Ulsan, Yeosu Gwangyang). In order to increase the accuracy of the analysis results, AHP analysis was conducted on 17 questionnaires with a consistency ratio of 0.1 or less. As a result of the analysis, it was confirmed that among the four areas representing the sustainability of domestic smart ports, the operation area had the highest priority, followed by the environment area. In addition, looking at the overall priorities for the 20 detailed indicators, indicators such as operational efficiency, operational planning, energy management, and pollution measurement and management system were found to have high priority. On the other hand, it was confirmed that the social and the governance areas had relatively low importance compared to other areas.

기후변화에 대비하여 한정된 수자원을 효율적으로 사용하기 위한 제도적 규제는 앞으로 기업의 제품 생산에서 발생하는 오염까지 확대될 전망이다. 기관투자가 등이 지원하는 영국의 NPO인 탄소정보공개프로젝트(CDP)는 2010년부터 온실가스배출량과 함께 물 사용 상황을 공개할 것을 전 세계 기업에 요구했다. 이에 따라 전 세계에서 탄소발자국과 물발자국에 대한 연구가 활발하게 진행 중에 있다. 우선 본 연구는 선진국을 중심으로 진행되고 있는 물발자국 개념의 활용현황을 분석하였다. 호주와 미국을 비롯한 일부 국가에서는 물발자국의 라벨 제도를 도입하여 기업의 제품에 대한 등급을 구분하고 있다. 라벨의 부착은 인증기관의 검토를 통하여 기존 제품보다 물 사용 효율이 높다는 것을 의미하며, 물발자국 라벨제도는 제품 생산의 전 과정 환경성 평가를 통하여 기업이나 제품의 물발자국 관련 영향을 줄이는 것을 목표로 하고 있다. 또한 스페인에서는 물발자국을 물의 효율적인 분배와 사용을 위한 정책적 요소로 도입하였다. 이상의 분석을 바탕으로 물발자국의 기술적 활용 및 효과를 도출하기 위하여 법과 제도적 측면, 기술적 측면에서 살펴보았으며, 우리나라의 현황과 비교를 진행하였다. 이와 관련하여 분야별 기술 사업에 대한 목표와 최종성과물, 활용방안을 정리하여 해당 개념의 주요쟁점사항에 대해 기술적, 정책적으로 타당한지를 지표를 설정하여 분석하였다. 물발자국의 활용에서 기술적 타당성에 대한 지표는 적절성, 성공가능성, 우수성, 경제성 측면에서 제시가 되었으며, 정책적 타당성은 해당계획 및 기업 및 지자체의 추진의지, 위험요인, 특수평가 항목을 통해 개업 및 지자체의 물발자국 활용 타당성을 분석하였다. 이상을 바탕으로 본 연구에서는, 물발자국 도입을 위한 종합평가로서 AHP 분석을 실시하여 물발자국 도입을 위한 중요도와 종합목적 및 위기상황에 따른 대체안을 설정할 수 있도록 우선순위를 도출하였다. 현재 우리나라는 본격적인 정책적 도입에 앞서 개념의 정의, 정책 공감대의 확대, 한국형 데이터베이스를 구축하는 시범단계에 있다. 물 산업의 확대와 우리 기업들의 해외진출은 가상수와 물발자국의 데이터베이스의 구축이 시급하다는 것을 보여준다. 따라서 본 연구는 앞으로 우리나라의 물발자국 도입을 위한 방향을 설정할 수 있는 기초연구로서 큰 의미를 지니며, 기업의 물산업 전략을 수립을 위한 지표 설정에 있어서도 기초자료를 제공할 수 있을 것으로 기대된다.

21세기에 들어 홍수의 규모가 대형화 되었고, 그 발생빈도 및 강도도 증가하고 있다. 최근에는 지구온난화가 지속화되면서 전 세계적으로 높은 강도의 기상이변들이 속출하고 있고, 이러한 이상기후에 따른 태풍, 집중호우 등의 대규모 호우로 인해 댐 및 제방 등의 수공구조물 붕괴와 같은 비상상황이 초래 될 수 있다. 이와 같은 피해들을 통해 홍수 침수 범위의 예측, 분석을 통한 홍수위험 및 다양한 홍수위험지도 작성의 필요성이 대두되었고, 실제로 국가 차원의 홍수위 험지도가 제작되고 있다. 특히, 홍수 위험도 분석에 있어서 홍수에 노출된 지역의 인구수, 홍수에 노출된 지역에서의 경제적 활동의 형태, 홍수가 발생했을 때 2차적 피해를 불러올 수 있는 설비 등을 나타내는 홍수 취약도(Flood Vulnerability)에 대한 정량적 평가는 홍수위험지표 및 홍수위험강도 등에 의한 Flood Risk 개념을 기반으로 한 홍수위험지도 제작을 위해 매우 중요한 사항이라 할 수 있다. 그러나 현재까지의 홍수취약도 산정방법은 방법론적인 면에 있어 다소 단순하고, 직관에 의한 위험도의 분류가 이루어지고 있는 실정이다. 또한 취약도 지표의 산정과정이 전문가의 의견에 의존하는 경우가 많아 홍수 취약도 선정과정과 가중치 결정과정에 전문가들의 주관이 개입되는 등 홍수위험지표의 정량화에 어려움을 겪는 경우가 많다. 본 연구에서는 위와 같은 문제를 극복하기 위해 Flood Risk Mapping 기술의 적용에 있어 중요한 요소인 홍수취약도를 다기준의사결정법에 의해 산정하고, 국내 낙동강 유역에 대해 행정구역별로 세분화된 홍수위험지도 제작을 위한 취약도 지표를 산정하고자 하였다. 이를 위해 다기준의사결정법중의 하나 인 PROMEETEE와 ELECTRE를 이용하여 민감도, 노출도, 저감성 지표를 낙동강 유역에 대해 정량화하여 도시하였다. 본 연구결과를 통해 홍수위험지표 및 지수들의 결합에 대한새로운 방법론을 제시하고, 그에 따른 지도화 기법을 확립할 수 있을 것으로 기대된다.

PMS (Pavement Management System) of National highways in Korea has used HDM (Highway Development and Management)-4 developed by World Bank for decision-making for maintenance and rehabilitation of pavements. However using HDM-4 is not appropriate in Korea because HDM-4 requires excessive input factors for analysis and economic analysis models loaded in HDM-4 are not suitable for Korean circumstances. Thus this study aims development of decision-making system for effective pavement management with reflecting Korean circumstances. Moreover this study proposed to define component of system, deterioration models, and basic units for component, and to analyze characteristics of component of system, and also to develop optimal decision-making system. The decision-making system for PMS mainly consists of 1) DB of highways, traffics, and socio-economic index, 2) pavement deterioration model, 3) speed prediction models by pavement conditions, 4) economic evaluation models, and 5) decision-making supporting system. Also this study provided analysis results in case studies for system verifications. However pavement deterioration models considering future probabilistic characteristic and index of decision-making are needed to develop for a further study.

This study was to analyze dynamics of host regional effect in accordance with Mega-events. Yeosu Expo, 2012 was the Mega-event, and dynamic changes in economic indicators such as number of tourists, GRDP, employment rate, and real estate price were analyzed before and after the event. The Mega-event affected positively and increased on the number of tourists. While GRDP affected positively only right before the event, and the employment rate was not significantly affected by the event. The real estate price was increased from the announced time of hosting to the event held, but later decreased. This study suggested the comprehensive method for analyzing the effect of Mega-event and there was a cyclical causality among the result variables.

This paper examines Korea's top 30 authors, in the maritime transportation field to compare their world ranking. The analysis covers the affiliation of the authors and their articles published in 65 SSCI and SCI journals on maritime and transportation over a 16-year period (2000-2015). The following three indicators are used for ranking: number of papers; the weighted score that reflects the contribution of the authors; and the impact score, which considers the impact factor. The two most active two schools are Pusan National University and Inha University. Star players are deemed to have contributed greatly to boosting the ranking of their affiliated institution. The institutions that are located in a city that is a seaport show higher research outcomes. Because of the fall in the proportion of Korean papers in the total papers published globally on maritime transportation, the country's future rankings are likely to suffer.

As country try expand R&D investment and enhance its efficiency to improve the national competitiveness, research is needed to conduct qualitative enhancement and derive progressive future strategy in relation to the academic information distribution project in scientific technology field. In this study, BSC-based performance indicators were applied to an institute that is the representative of domestic academic information distribution institutes in the field of scientific technology to evaluate project performance, and then to analyze portfolio of using such evaluation results. As for the items of evaluation for the performance indicators of academic information distribution project in the scientific technology field, 12 items that includes information resource quality, information service quality, user satisfaction and economically useful value of academic information from four(4) viewpoints such as information resource, information service, user and economic viewpoints. In the portfolio analysis, it was conducted by performance indicators and by elements of the individual performance indicators as well. Based on the results of performance evaluation and portfolio analysis, the improvement method by viewpoints on academic information distribution project of an institute was suggested.

Recent migration is led by skilled labor, This paper performes a cross-country analysis to find the determinants of skilled migration using recently released Doquier and Marfouk(2005) data as dependent variable and economic indicators of nations as independent variables. Regression results show that the skilled migration to OECD countries are driven not only by income motive but also by structural factors, such as industrial structure and life expectancy, which have broader meanings in development. It is noteworthy that structural factors of a nation become more important as its income level rises. English seems to have positive effect on skilled migration. Some region-specific factors, proximity to USA of Caribbean countries and political instability of Gold Coast countreis, for example, are found. Middle-income countries seem to be the most vulnerable to the possible risk of brain drain.
