지하도로는 주변 도심개발 등으로 수평적 도로용량 확장이 어려운 구간을 대상으로 입체적 활용을 통해 교통혼잡을 해소하기 위한 수단으로써 주목받고 있다. 그러나 지하도로는 공간 특성상 지상에 비해 다양한 불확실성이 수반된다는 면에서 위험요인이 크고 직접 건설비용이 큰 사업으로 인식되기도 하며, 최근 관련 안전·방재 및 설계 요소 관련 법령과 지침이 지속적으로 제·개정됨에 따라 사업 비 변동요인이 증가하고 있다. 따라서 향후 증가할 지하도로 민간투자사업 추진시에 발생하는 다양한 위험요인에 대한 관리방안 마련 이 필요한 시점이다. 이에 본 연구는 지하고속도로 민간투자사업의 특수성을 반영한 기본계획 단계의 기술부문 평가지표에 대한 배점 개선안을 제시하는 것을 목적으로 한다. 이를 위해 현재 제3자 제안 공고상 기술 부문의 평가 배점을 검토하고, 신규 평가항목이 포함 된 후보 평가지표를 제시하였다. 또한 분석적 계층화 기법(AHP) 기반의 전문가 설문조사를 수행하여 평가지표의 우선순위를 도출해 최종적인 지하 고속도로 평가지표의 배점을 도출하였다. 평가항목별 배점 결과 건설계획 분야에는 ‘공사비, 보상비 등 사업비 선정(10 점)’, ‘장대터널계획 종합(25점)’, ‘시·종점부 도로접속 및 교통운영(18점)’ 평가항목이 추가되었다. 사업관리 및 운영계획 분야에는 ‘안 정적 운영을 위한 계획수립(76점)’, ‘운영계획의 창의성(24점)’, ‘재해 및 재난관리계획(21점)’ 등의 순으로 배점이 수정되었으며, 특히 시설 및 장비확보 계획, 유지보수 계획, 교통 및 영업관리 계획 등이 고려되는 ‘안정적 운영을 위한 계획수립’ 평가항목의 배점이 크게 증가하였다. 본 연구에서 제시한 배점 개선안을 통해 기본설계 단계에서부터 지하 고속도로 민간투자사업의 위험요인과 특수성을 고 려하여 사업을 추진할 수 있을 것으로 판단된다.

In this study, the AHP (analytic hierarchy process) technique was used to analyze the risk of expected risk factors and fishing possibilities during gillnet fishing within the floating offshore wind farms (floating OWF). For this purpose, the risks that may occur during gillnet fishing within the floating offshore wind farms were defined as collisions, entanglements, and snags. In addition, the risk factors that cause these risks were classified into three upper risk factors and ten sub risk factors, and the three alternatives to gillnet fishing available within the floating OWF were classified and a hierarchy was established. Lastly, a survey was conducted targeting fisheries and marine experts and the response results were analyzed. As a result of the analysis, among the top risk factors, the risk was the greatest when laying fishing gear. The risk of the sub factors for each upper risk was found to be the highest at the berthing (mooring), the final hauling of fishing net, and the laying of the bottom layer net. Based on the alternatives, the average of the integrated risk rankings showed that allowing full navigation/fisheries had the highest risk. As a result of the final ranking analysis of the integrated risk, the overall ranking of allowing navigation/fisheries in areas where bottom layer nets were laid was ranked the first when moving vessels within the floating OWF was analyzed as the lowest integrated risk ranking of the 30th at the ban on navigation/fisheries. Through this, navigation was analyzed to be possible while it was analyzed that the possibility of gillnet fishing within the floating OWF was not high.

국제해사기구에서는 해상에서의 선박의 충돌방지와 그로 인한 해양환경의 보호를 목적으로 1993년 11월 선박조종성능에 대 한 잠정지침을 채택한 이후, 축적된 데이터를 바탕으로 2002년 12월 선박조종성능에 대한 확정된 지침을 채택하였다. 하지만 채택된 지침은 만재상태, 등흘수 및 선박의 최대 출력(MCR)의 85 %에 해당되는 선속의 최소 90 % 이상에서의 지침으로, 동 지침은 항해사에게 필요한 실 항해조건에서의 조종성능 정보를 제공하는 데 한계가 있다. 따라서 본 연구에서는 항해사, 선장 및 선박조종에 대한 식견을 갖추고 있는 전문가를 대상으로 빈도분석과 AHP 분석기법을 실시하여 현 지침에 대한 활용도 및 실제 선박조종에 필요한 정보가 무 엇인지를 식별하였다. 연구결과 선박을 운항하는 항해사에게 필요한 조종성능 정보는 5~10°의 소각도에서의 선회권 정보, 항해속력(Sea speed)이 아닌 조종속력(Maneuvering speed)에서의 z-test 정보라는 것을 확인하였고, 속도제어 관련하여서는 항해속력 및 만재상태에서의 정지성능에 대한 정보보다 감속타력, 가속타력 등에 대한 정보가 더 필요하다는 것을 확인하였다. 도출된 결과는 선박을 조종하는 항 해사에게 필요한 선박조종성능기준 지침마련에 대한 기초자료로 활용도가 높을 것으로 사료된다.

PURPOSES : The purpose of this study was to investigate directions for future smart city transportation policies and service development by evaluating road service satisfaction levels and predicting future service demand. METHODS : A nationwide survey was conducted in Korea to develop a transportation service evaluation system based on the functions and objects of transportation. The satisfaction level of road service was evaluated using an analytic hierarchy process (AHP), promising service sectors were identified using the revised importance-performance analysis (IPA) technique, and detailed service demands by sector were suggested. RESULTS : The most valuable service value felt by the people was "safety" (weight 0.4), and the overall satisfaction level was 68.9 points, slightly exceeding "normal." As a result of analyzing the promising service sectors by dividing them into urban and rural areas, "handicapped, elderly, and pedestrians" were important in both areas, and "road facility maintenance" was classified as an additional promising sector for rural areas. CONCLUSIONS : People demand that future smart city transportation policies and services should be "people" and "safety" centered. In addition, it is necessary to pay attention not only to the development of new services but also to the improvement of problems with existing services and policies.

Non-face-to-face lectures have become a necessity rather than an option since COVID-19, and in order to improve the quality of university education, it is necessary to explore the properties of non-face-to-face lectures and make active efforts to improve them. This study, focusing on this, aims to provide basic data necessary for decision-making for non-face-to-face lecture design by analyzing the relative importance and execution satisfaction of non-face-to-face lecture attributes for professors and students. Based on previous research, a questionnaire was constructed by deriving 4 factors from 1st layer and 17 from 2nd layer attributes of non-face-to-face lectures. A total of 180 valid samples were used for analysis, including 60 professors and 120 students. The importance of the non-face-to-face lecture properties was calculated by obtaining the weights for each stratified element through AHP(Analytic Hierachy Process) analysis, and performance satisfaction was calculated through statistical analysis based on the Likert 5-point scale. As a result of the AHP analysis, both the professor group and the student group had the same priority for the first tier factors, but there was a difference in the priorities between the second tier factors, so it seems necessary to discuss this. As a result of the IPA(Importance Performance Analysis) analysis, the professor group selected the level of interaction as an area to focus on, and it was confirmed that research and investment in teaching methods for smooth interaction are necessary. The student group was able to confirm that it is urgent to improve and invest in the current situation so that the system can be operated stably by selecting the system stability. This study uses AHP analysis for professors and students groups to derive relative importance and priority, and calculates the IPA matrix using IPA analysis to establish the basis for decision-making on future face-to-face and non-face-to-face lecture design and revision. It is meaningful that it was presented.

PURPOSES : In this study, drone highway route alternatives were evaluated using the analytic hierarchy process (AHP) technique to investigate any difficulties or improvements while designing drone highway routes. METHODS : Based on the literature review and AHP analysis, 39 road and airport experts were surveyed to evaluate two alternate drone highway routes that connect the Seoul train station and Jamsil park near Gangnam business district. RESULTS : The AHP analysis results revealed that the environmental aspect was the most critical factor in designing a drone highway route, followed by social and technological factors. Among the investigated factors, noise and life-environment showed the highest geometric mean value of 0.21. This mean should be considered when developing plans and policies for drone highway design. CONCLUSIONS : Environmental and social agreement is more crucial than the technological and economic aspects when designing drone highway routes. Laws and policies should be updated and followed to support the drone highway system, which is vital in logistics.

Recently the meaning of the road name address is expended as an information through the revision of the Road Name Address Act. As this revision, the address of things (AoT) become more important indicating the possibility for the expansion to the related business. However, recent study about AoT does not concern how the current priority system works from the first research. In this study, we analyze perception about addressable object between AoT experts and public using AHP analysis. We structured the importance of addressable objects as two categories; urgency and value creation. The necessity in emergency or daily, accessibility and welfare conform the urgency index. Meanwhile, public value creation in public domain or profitability in the business area and economics conform value creation index. We conducted survey for total of 89 of experts and public. The results of this study indicate the relative importance of AoT measured by experts and public. Generally, public tend to concern more about accessibility conforming the urgency index than experts. Moreover, the public WiFi and the sports complex scored the high priority among the remain addressable objects, in respect of the urgency and the value creation. This result could be implemented for the activation of the smart city industry base on the geospatial information including AoT.

Recently the concentration of fine dust and ultra fine dust becomes so bad, which seriously threatens the health and even the life of people. So, government started to investigate several ways to reduce the amount of fine dust and ultra fine dust. From a few years ago it has been known that ships anchored at port emit a lot of pollution and seriously affect air quality of neighboring cities. To reduce the pollution emitted by ship AMP (Alternative Maritime Power Supply) has been proposed, which uses the electricity instead of bunker C oil or diesel. Many developed countries already installed AMP to improve air quality in port area. Korea is in the stage of planning to install AMP at port. However, there are many complicated problems to be handled before AMP installation. Due to huge initial cost and long period of construction ship owner and habour operating company are reluctant to AMP installation. And there are serious technological difficulties in constructing AMP in existing harbour. Lack of AMP core technology and operational difficulties of AMP are also big challenges to be conquered. In this study SWOT/AHP method is used to find strategic and efficient ways to handle above complicated challenges and then to vitalize the AMP installation.
