Port terminals, as the starting and ending points of the technological process in the transport of goods, are also logistic centers for the provision of services of loading/unloading and storage of goods. Improving the process of transporting goods and achieving competitiveness is not possible without quality port service and customer satisfaction with the service provided, and reduction of traffic congestion and environmental pollution within the guards in which the ports are positioned.This scientific research aimed to analyze, using scientific methodology, the factors influencing the assessment of port service quality and intermodality in the Port of Rijeka and to develop a model for port service quality assessment by implementing fuzzy logic. The model was tested by simulation based on the evaluation of the criteria of influential parameters with inaccurate and indeterminate input data. The test results provide an assessment of the quality provided by port service and intermodality. The results of the research will be used to improve the transport service planning process to achieve greater competitiveness for the port.
港口码头作为货物运输技术过程的起点和终点,同时也是提供货物装卸和仓储服务的物流中心。如果没有优质的港口服务和客户对所提供服务的满意度,以及减少港口所处守卫区内的交通拥堵和环境污染,就不可能改善货物运输过程并实现竞争力。本科学研究旨在运用科学的方法分析影响里耶卡港港口服务质量和多式联运评价的因素,并运用模糊逻辑建立港口服务质量评价模型。在输入数据不准确和不确定的情况下,通过对影响参数准则的评估,对模型进行了仿真验证。测试结果对港口服务和多式联运提供的质量进行了评估。研究结果将用于改善运输服务规划过程,以提高港口的竞争力。

This paper reflects upon the concept of social innovation and its role in islands’ energy transition. As isolated energy systems, islands typically depend on energy imports from the mainland and mostly use fossil fuels for electricity, heating, and transport, which are significant sources of carbon emissions. At the same time, islands have an abundance of locally available renewable energy sources (RES) at their disposal, which makes them ideal test-beds for energy transition, or the technology-based switch of the energy system, from fossil-based to renewable energy. However, new RES technologies must be incorporated into society and, thus, to enable successful decarbonisation, technological innovations must be coupled with social innovations. Different authors stress that energy transitions are not strictly technical but socio-technical since they are also comprised of policies, politics and other artefacts, not just technological. Nevertheless, the role of social innovation in local energy transitions is still under-studied, and this paper aimed to contribute to this lack of literature, focusing on the local energy transitions of islands.By combining theoretical and empirical research, this paper aims to explore the role of social innovation in energy transition and analyse whether social innovation can be considered a success factor in the energy transition process of the case-study island, the small Croatian island of Unije.
本文对社会创新的概念及其在海岛能源转型中的作用进行了反思。作为孤立的能源系统,岛屿通常依赖从大陆进口的能源,主要使用化石燃料发电、供暖和运输,这些都是碳排放的重要来源。与此同时,岛屿拥有丰富的本地可再生能源,这使它们成为能源转型或能源系统从化石能源向可再生能源的技术转换的理想试验台。然而,新的可再生能源技术必须融入社会,因此,为了实现成功的脱碳,技术创新必须与社会创新相结合。不同的作者强调,能源转型不是严格意义上的技术转型,而是社会技术转型,因为它们也包括政策、政治和其他人工制品,而不仅仅是技术。然而,社会创新在地方能源转型中的作用仍在研究中,本文旨在弥补文献的不足,重点关注岛屿的地方能源转型。本文将理论研究与实证研究相结合,旨在探讨社会创新在能源转型中的作用,并分析社会创新是否可以被视为克罗地亚小岛乌尼耶能源转型过程中的成功因素。

Shipping containers are known as a crucial equipment for global trade. Most of their lifespan containers are spending empty, being in process of repositioning or sitting in a yard. Increasing trade imbalances globally set up empty container logistics as one of the main concerns in container shipping industry. In line with that issue, this paper will analyse the roots of empty container imbalance and port congestion, emphasizing the importance of proper empty container management and challanges which appear along the way. Results of the research show that there is room for improvement while dealing with management of empty containers which primarly implies a cognition of the imbalance problem and long-term predictions as well as mutual cooperation of all parties involved. Furthermore, new solutions and higher level of digitalization will be required to succesully and efficiently handle today’s challanging situations. Reducing empty container transport to a minimum is the key point, where foldable containers and container interchange between carriers can greatly contribute. Efficiency of empty container management must be reflected in increased environmental sustainability throughout the shipping process.
众所周知,集装箱是全球贸易的重要设备。它们使用寿命的大部分容器都是空的,正在重新定位或放在院子里。全球贸易失衡加剧,使得空箱物流成为集装箱运输业的主要问题之一。针对这一问题,本文将分析空箱不平衡和港口拥堵的根源,强调妥善管理空箱的重要性以及随之而来的挑战。研究结果表明,在处理空集装箱管理方面还有改进的空间,这主要意味着对不平衡问题的认识和长期预测,以及相关各方的相互合作。此外,还需要新的解决方案和更高水平的数字化,才能成功有效地应对当今的挑战。将空集装箱运输减少到最低限度是关键,可折叠集装箱和承运人之间的集装箱交换可以在很大程度上发挥作用。空集装箱管理的效率必须反映在整个运输过程中环境可持续性的提高上。

In this study, the environmental footprint within a designated area is determined by an inventory of air pollutants (including toxic and greenhouse gases) emissions generated. The designated area of concern is the port of Dubrovnik, a well-known cruise ship destination, where a major source of pollutant emissions is the diesel engines of the ships operating in the port. This research was undertaken for the port of Dubrovnik in connection with the development of the national strategy and the need for determining the inventory of air pollutants. It was conducted for the last pre – COVID- 19 year, 2019. In this paper, after a short introduction, the basic data of the port of Dubrovnik and the marine traffic (predominantly cruisers) in 2019 are provided, obtained from publicly available data. Next, the emission estimate methodology based on a bottom-up approach is described. The inventory analysis was undertaken from the port boundary to the PWD (pier/wharf/dock) and back. The basic equations for evaluation during cruising, maneuvering, and hoteling are given along with the corresponding data. The aggregated results are presented in the form of tables and column charts. These results show that the generation of CO2 highly dominates. Regarding the pollution analyzed NOx dominates. The results of this study could be of interest for later studies on environmental pollution in the region of Dubrovnik-Neretva County and the Croatian coast.
在本研究中,指定区域内的环境足迹是由产生的空气污染物(包括有毒气体和温室气体)排放清单确定的。指定的关注区域是杜布罗夫尼克港,这是一个著名的游轮目的地,在该港口运营的船舶的柴油发动机是污染物排放的主要来源。这项研究是为杜布罗夫尼克港进行的,与制定国家战略和确定空气污染物清单的需要有关。该调查是在2019年COVID- 19前的最后一年进行的。在本文中,经过简短的介绍,提供了2019年杜布罗夫尼克港和海上交通(主要是巡洋舰)的基本数据,这些数据来自公开数据。其次,介绍了基于自底向上方法的排放估算方法。清单分析是从港口边界至PWD(码头/码头/码头),然后返回。给出了巡航、机动和停留时的基本评价方程和相应的数据。汇总结果以表格和柱状图的形式呈现。这些结果表明,CO2的生成占主导地位。在污染分析中,氮氧化物占主导地位。这项研究的结果可能对以后关于杜布罗夫尼克-内雷特瓦县区域和克罗地亚海岸的环境污染的研究有意义。

The hazards that particularly affect local coastal communities require education that is conducive to the development within planetary boundaries. The paper analyses the features of education for resilience and sustainability based on good practice and the principles stipulated in strategic documents on sustainable development issued by international organizations and professional associations. In developing the curricula for strengthening resilience, focus should be placed on deeper learning about local knowledge, on stimulating local sustainability, systems thinking, integrating teaching about the environment and responsible citizenship into all school subjects. To achieve the objectives proposed it is necessary to enhance whole-institution approach and bridge the divide between the subjects in humanities and STEM areas by providing courses which afford insights into connections between various disciplines required for perceiving local and global issues and the solutions thereto, and to implement citizen science. Resilience thinking should be embedded in planning and strategic environmental assessment procedures for a wide range of themes and activities affecting coastal area environment and its communities.
特别影响当地沿海社区的灾害需要有利于在地球范围内发展的教育。本文根据良好实践和国际组织和专业协会发布的可持续发展战略文件规定的原则,分析了韧性和可持续教育的特点。在制定加强复原力的课程时,重点应放在更深入地学习当地知识、促进当地的可持续性、系统思考、将有关环境和负责任的公民身份的教学纳入所有学校科目。为达致上述目标,我们有必要加强全院合作,并透过提供课程,让学生了解不同学科之间的联系,以了解本地和全球问题及其解决方案,从而弥合人文学科与STEM学科之间的鸿沟,并推行公民科学。对影响沿海地区环境及其社区的各种主题和活动的规划和战略环境评估程序应纳入复原力思想。

As an archipelagic country, Indonesia has a concentrated deposit of salt in Java and Madura Island. Furthermore, the total demand for the mineral in 2017, 2018, and 2019 were 3.9, 4, and 4.2 million tons, respectively. This study was carried out in 4 stages, namely identification of raw materials, crystallization, mechanical, and re-crystallization. The salt crystallization and purification process is beneficial to the aquaculture, fishery, and health sectors. The results showed that the raw materials obtained from the coastal areas of East Java and Bali Island have an average NaCl interval estimation range of 80.31% to 92.37%, which indicates that they are suitable for salt production. The product obtained from the processes have the potential to initiate diversification of business development in the country with an estimation range of 95.38% to 97.25%.

The enhancement of world maritime shipping leads to increasing of the time required for transit passage and impossibility of old locks in Panama Canal to serve the newest vessel’s generation. Many states in east and south-eastern part of the country, as Florida, Georgia, Virginia and South Carolina, are becoming attractive for business. They have made various investments and improvements in regional transport infrastructure to dominate over freight traffic in the region, such as dredging of port entrances and port basins, expansion of container terminals, and improving inland transport connections to the port. The goal of this article is to study how the design and construction of new set of locks on the Panama Canal affects to the global trade and further to the multimodal chains, transport infrastructure and ports along the East American Coast.

Compliance with modern environmental norms and regulations is an increasingly important requirement in the shipbuilding process of ship design and construction. Related to the ship production process, volatile organic compounds (VOCs), nitric oxides and particulate matter are the main emissions of harmful gases in the shipyard. This paper analyzes air emissions from the ship production process in a shipyard. Air emissions are quantified from either in-situ measurements from emission sources, or by materials that are used in the shipbuilding process, and the acquired data from those measurements is calculated as yearly emissions. Emission quantities of VOCs, nitric oxides, carbon dioxide, carbon monoxide and particulates are analyzed regarding possible reduction techniques considering efficiency and investment costs for using these methods. In conclusion, the best available and feasible emission reduction methods are suggested, and a suggestion for achieving the goal of a net zero emission shipyard.
在船舶设计和建造过程中,符合现代环境规范和法规是一项越来越重要的要求。在船舶生产过程中,挥发性有机化合物(VOCs)、一氧化氮和颗粒物是船厂排放的主要有害气体。本文对某船厂船舶生产过程中的大气排放进行了分析。通过对排放源的现场测量或造船过程中使用的材料对空气排放进行量化,并从这些测量中获得的数据计算为年排放量。考虑到使用这些方法的效率和投资成本,就可能的减排技术分析了挥发性有机化合物、一氧化氮、二氧化碳、一氧化碳和颗粒物的排放量。最后,提出了可行的最佳减排方法,并对实现船厂净零排放的目标提出了建议。

During the last decades, the international practice has indicated that maritime disputes among coastal states have erupted as a result of direct infringements of maritime jurisdiction and rights of one coastal state towards another. These maritime disputes involve many aggravated issues and problems reflecting often conflicts of international nature which have to be tackled and given an appropriate resolution to avoid a possible escalation of a maritime conflict or crisis. The most problematic and dangerous cases related to these maritime conflicts are the maritime zones’ delimitation among coastal states which as their mechanism of sovereignty may utilize their armed forces to resolve the relevant disputes, considered very sensitive and paramount matters of national interests. The maritime dispute between Albania and Great Britain in the Corfu Channel incident is considered an aggravated interstate conflict where the armed forces of both coastal states confronted each other with lethal and extreme use of force. To avoid such a dangerous confrontation of maritime interests which can have dire consequences for international or regional peace and stability, the international organization such as the United Nations has adopted legal instruments for the resolution of maritime disputes through peaceful mechanisms and legal approaches such as international tribunals, international maritime conventions as well as diplomatic channels and political negotiations. It is the main objective of this article to examine these legal approaches and instruments to identify the legislative advantages and legal issues which may influence possible future maritime disputes among states.
在过去几十年中,国际惯例表明,沿海国之间的海事争端是一个沿海国对另一沿海国的海事管辖权和权利受到直接侵犯的结果。这些海事争端涉及许多严重的问题和问题,这些问题往往反映出国际性质的冲突,必须加以解决并给予适当的解决,以避免海事冲突或危机可能升级。与这些海上冲突有关的最有问题和最危险的案例是沿海国之间的海域划界,作为其主权机制,沿海国可以利用其武装力量解决相关争端,这些争端被认为是非常敏感和最重要的国家利益问题。阿尔巴尼亚和英国在科孚海峡事件中的海上争端被认为是一场加剧的州际冲突,两个沿海国家的武装部队以致命和极端的武力对抗。为了避免这种可能对国际或区域和平与稳定造成可怕后果的危险的海洋利益对抗,联合国等国际组织通过了通过和平机制和国际法庭等法律途径解决海洋争端的法律文书,国际海事公约以及外交渠道和政治谈判。本文的主要目的是审查这些法律方法和文书,以确定可能影响国家间未来可能发生的海事争端的立法优势和法律问题。

The aim of this paper is to evaluate development partnership scenarios of the seaports in the Republic of Croatia using the Multi-Actor Multi-Criteria Analysis (MAMCA). Previous author’s research indicated a number of effects and criteria that PPPs need to achieve in order to ensure sustainable port development. However, implementation of partnership models in seaports in the Republic of Croatia has not reached its full potential although there has been significant progress over the last ten years. For that reason, the evaluation of the partnership models in Croatian seaports is a poorly researched issue. The author has defined three models of port development according to the degree of private investors’ involvement in Croatian ports (status quo, minimal participation and maximal participation of private sector). The author uses MAMCA as a tool to evaluate the PPP model, using relevant criteria for the evaluation of public-private partnerships (economical-financial, organizational, technical-technological, social criteria and the criteria aiming at harmonization with the policies of the European Union), from relevant stakeholders’ point of view (public interest, private interest and the interest of the wider community). The research results show that the best-evaluated model is maximal participation of private sector. It has positive influence on port development from economic and technological side, it directly contributes to different stakeholder’s interests, and in the long term, it contributes to the local community development.
本文的目的是利用多参与者多标准分析(MAMCA)来评估克罗地亚共和国海港的发展伙伴关系方案。前作者的研究表明,为了确保港口的可持续发展,ppp需要达到一些效果和标准。然而,在克罗地亚共和国的海港实施伙伴关系模式尚未充分发挥其潜力,尽管在过去十年中取得了重大进展。因此,对克罗地亚海港的伙伴关系模式的评价是一个缺乏研究的问题。作者根据私人投资者参与克罗地亚港口的程度确定了三种港口发展模式(现状、最低参与和私营部门最大参与)。作者使用MAMCA作为评估PPP模式的工具,从相关利益相关者的角度(公共利益、私人利益和更广泛的社区利益),使用评估公私伙伴关系的相关标准(经济-金融、组织、技术-技术、社会标准和旨在与欧盟政策协调一致的标准)。研究结果表明,最优评价模式是民营企业最大参与。它从经济和技术方面对港口发展有积极的影响,它直接有助于不同利益相关者的利益,从长远来看,它有助于当地社区的发展。
