Active Harbor City revitalization: stitching existing urban fabric and port redevelopments in Busan, Korea

Lee, JinAh 11 July 2013 (has links)
This study is to propose spatial interventions to activate port areas in the harbor city, Busan. Many ports including Busan North Port redevelopment are expected to redevelop soon. Most of them will be changed existing industrial ports to waterfront facility. However, these developments do not consider existing urban context. To resolve this problem, I suggest infrastructures and public spaces between existing urban structure and expected developments. This plan will increase accessibility to waterfront area and provide active public spaces. Especially, this study focuses on Busan North Port area. I propose an athletic park for local people and four pedestrian bridges to connect between city downtown and Busan North Port. / text

Socioeconomic Impacts of Transitioning to Collaborative Port Operations - A case study of the Port of Gothenburg

Merkel, Axel January 2015 (has links)
The purpose of this study is to derive a method for estimation of costs and benefits of implementing Port Collaborative Decision Making (Port CDM), and to apply this method to the Port of Gothenburg. By using the Port of Gothenburg as a case study, conclusions can be drawn regarding the economic viability of Port CDM in one of Scandinavia‟s largest ports. This study considers two major sources of benefits that are hypothesized to result from transitioning to collaborative port operations: improved possibilities for speed optimization prior to arrival in port due to increased predictability in estimated berthing times, and shortened service times due to increased possibility for planning and resource optimization by port service providers.The estimation of impacts is based on one month‟s traffic data in the Port of Gothenburg. Predictability of estimations is analyzed to determine the benefit potential of Port CDM. The estimated cost savings for cargo vessels can be divided into 5 categories: bunker, emission, time, manning and capital cost savings. The costs of implementing and maintaining Port CDM are estimated with values from relevant previous research.The results of this study indicate that the implementation of Port CDM in the Port of Gothenburg is a profitable investment, for the shipping industry and for society as a whole. The estimated annual net benefit is 27.3 million euros. A sensitivity analysis using alternative unit valuations for emissions, as well as low and high estimations of the effectiveness of Port CDM, indicates that the economic viability of the project is robust under all assumptions considered.

Awareness and importance of CentrePort’s features and possible links to lean logistics

Adelman, Matthew 12 September 2015 (has links)
This study investigates awareness and importance of, and knowledge about, features of CentrePort Canada, in the eyes of the Winnipeg supply chain community. CentrePort is the inland port located in Winnipeg, Manitoba. A questionnaire focused on features of CentrePort was sent via e-mail to supply chain professionals in the Winnipeg area. This was done through the cooperation of two supply chain organizations and their chapters in Winnipeg. Respondents are aware of certain more heavily advertised aspects of CentrePort. Most of the features are rated relatively important by the respondents. However, the lean alignment of an organization seems to have little impact on the importance of CentrePort’s features, and the respondents are ultimately not confident in their knowledge about CentrePort. While respondents are aware of the physical space that CentrePort occupies, they are very much unaware and uninformed of CentrePort’s nuances. / October 2015

A Port and Its Hinterland: An Environmental History of Izmir in the Late-Ottoman Period

Inal, Onur January 2015 (has links)
This dissertation, based on Ottoman, Turkish, British, French, American, German, and Italian archival and published primary sources, tells the story of transformation of Izmir and its surrounding area in the late Ottoman period through the perspective of environmental history. In this period, roughly in the decades between the 1840s and 1890s, Izmir, thanks to the human and natural resources in its hinterland, grew rapidly in export trade and evolved into a gateway city, linking the fertile Western Anatolian valleys to world markets. By discussing the economic and ecological transformations in the Western Anatolian countryside, this dissertation aims to show that nature was a historical actor and an active factor in the social, economic, and environmental changes in Izmir and its hinterland in the late Ottoman Empire. In other words, by using the lens of environmental history, this dissertation seeks to document and analyze the interplay between the city and countryside and produce a unified history of Izmir and its hinterland in the late Ottoman period.

The Other 90%: Infrastructural Components for the Masses, Port-au-Prince, Haiti

Towell, Jessie 10 January 2013 (has links)
Port-au-Prince, Haiti, along with many dense cities in developing countries, are stifled by their rudimentary, undersized and poorly maintained waste, water and sanitation infrastructural systems. Port-au-Prince is a city already plagued by poverty and overpopulation, and suffered a magnitude 7.0 earthquake in 2010 that devastated the already fragile republic. Flooded with Not-for-Profit and Non-Government Organizations (NFPs and NGOs) and billions of dollars of aid money following the earthquake, a new challenge arose in finding ways to utilize these new, uncoordinated resources efficiently without falling victim to dependency on aid money and other fleeting, external resources. The thesis proposes a series of infrastructural components for decentralized waste, water and sanitation that can address the cultural and infrastructural challenges of diverse sites within city, as city-wide systems have proved unsuitable and have not been maintained. The proposal deals with resources and wastes on-site, in order to reduce dependence on often expensive methods of waste collection and water provision. It diverts waste and excess water from ravines; reduces waste strewn throughout the city; creates community accountability and engagement, and in doing so, strives to improve quality of life. Waste is furthermore utilized in fueling other complementary processes, generating a micro-scale waste economy. The solution to making Port-au-Prince’s infrastructural systems viable and self-sustaining is to turn them into economic drivers that produce businesses and jobs through the collection, sorting, processing and re-use of wastes and water that in turn result in safer and more sanitary living conditions, as well as helping to re-organize a city destroyed by the earthquake into productive neighbourhoods with local community nodes.

Age and growth estimates for the Port Jackson shark, Heterodontus portusjacksoni, (Meyer, 1793) from New South Wales, Australia

Ramos, Robert January 2007 (has links)
Research Doctorate - Doctor of Philosophy (PhD) / World shark populations are declining rapidly from the increased demand for shark meat and fins and from their capture as by-catch. Techniques to accurately and reliably estimate the age of elasmobranchs are required to understand life history and develop management strategies. Although some biological information exists for the harvested species, few of the many shark species caught as by-catch have been investigated. In the waters of New South Wales, Australia, the Port Jackson shark (Heterodontus portusjacksoni) is a non-targeted species, however it is a major contributor to the elasmobranch by-catch in the bottom trawl and prawn fisheries. Although some biological and ecological information exists on Port Jackson sharks from New South Wales, there is no understanding of suitable techniques to age this species and of the age structure of the New South Wales’ population. Hence, the main purpose for the present study was to determine a suitable technique to age Port Jackson sharks and thereby provide essential age and growth data for its future management, sustainable use and conservation. This study consisted of research into: (1) the macroscopic anatomy of the vertebral centra and dorsal spines from 652 H. portusjacksoni to explore their suitability as ageing structures; (2) a comparison of whole and sectioned vertebral centra and of whole and sectioned dorsal spines for ageing; (3) validation of the annual formation of growth bands; (4) a comparison of the effect of prior experience on readers’ ability to count annual growth bands in vertebral centra; and (5) the development of age-growth models for the New South Wales’ population of H. portusjacksoni. Two types of vertebral centra (trunk and caudal vertebrae) were found in the vertebral column. Both vertebrae consisted of a centrum, 2 ribs, 4 neural arches, basiopophyses and neural foramen and decreased in size from anterior to posterior. A strong linear relationship was identified between vertebral diameter (VD) and fork length (FL). Each dorsal spine was positioned anterior to the dorsal fin and consisted of a stem and the cap. A strong linear relationships were identified between spine base width (SBW) and FL. The existence of alternating opaque and translucent band pairs in both structures further suggested they may be suitable for ageing purposes. Validation (calcein and oxytetracycline injections, marginal increment analysis, and centrum edge analysis) confirmed that translucent band pairs were formed during the winter (September-November) and were annual in both vertebral centra and dorsal spines. Whole and sectioned vertebral centra and dorsal spines were individually examined to determine which method best estimated the age. Although both methods had individual low reading bias and high precision, there was a difference between the two methods. The average bias between the two methods using vertebral centra was -0.158 ±0.05 and the coefficient of variance (CV) was 92.32% for females and -0.157 ±0.03 and CV was 56.95% for males. This indicated that sectioned vertebral centra returned higher ages than whole vertebral centra. When comparing whole dorsal spine age estimates to sectioned dorsal spines, there was an average bias between methods of -0.22 ±0.026 and a low precision 73.09%. Again indicating that sectioned dorsal spines returned higher ages than whole dorsal spines. A comparison of ages estimated from sectioned vertebral centra and sectioned dorsal spines showed that vertebral centra aged older than dorsal spines. Although the two structures each had low reading bias and high reading precision, there were differences between the two structures. The average bias between the two structures was -0.4 ±0.03 and the CV was low (74.7%), indicating that there was a significant difference in age derived from the two structures. Therefore, great caution should be taken when choosing which structure to use for age estimation. Ages of sharks estimated from the recommended sectioned vertebral centra ranged from 0.2 to 32.5 years for females and 0.2 to 23.8 years for males. Four different growth models were compared using both sectioned vertebral centra and sectioned dorsal spines to estimate the best suitable growth curve. Out of the 4 growth models the Gompertz Growth Function (GGF) best described the growth of H. portusjacksoni. von Bertalanffy growth parameters estimated from ageing data using the GGF for females were t0 = 2.584 yr, k = 0.111, L∞ = 1134.1 mm FL, and for males t0 = 1.629 yr, k = 0.131, L∞ = 1012.9 mm FL. This indicates that H. portusjacksoni has a slow growth rate and a longer life span than most other elasmobranch species. The effect of reader’s experience on the bias and precision of age estimates of sectioned vertebral centra was determined in an experiment that compared the author (an experienced vertebral centra reader) with an experienced fish otolith reader, two readers recently trained in reading vertebral centra (but lacking experience), and two untrained and inexperienced readers. Bias and precision were determined for each reader from two ageing trials with the same structure three months apart. Between-trials bias for each reader (except the author)ranged from 0.033 to 0.13 and precision ranged from 8.2 to 19.5%, while the author had low bias 0.006 and high precision 1.1%. When comparing all the readers with the author, bias ranged from 0.033 to 0.13 with an 8.2 to 19.5% precision for trial one, and 0.017 to 0.5 with precision between 2.5 to 5.4% in trial two. The age-bias plots comparing the two trials all indicated that only the author was consistent. And the age-bias plots between the author and the other readers all indicated that neither experience in ageing teleost otoliths or limited training in ageing enhanced the bias or precision compared to inexperienced elasmobranch agers.

Stormwater heavy metal loadings to Port Jackson estuary NSW, Australia

Rochford, Louisa January 2008 (has links)
Master of Science / Investigations of fluvial and estuarine sediments have indicated stormwater is an important source of heavy metals to Port Jackson estuary and high concentrations of these sedimentary contaminants are a threat to the healthy functioning of the estuarine ecosystem. Stormwater remediation devices have been installed in stormwater channels entering the estuary, however these devices are mainly for removing gross pollutants and are ineffective in removing heavy metals from stormwater. A thorough characterisation of heavy metal inputs and behaviour has been undertaken by sampling, analysing and modelling heavy metals in stormwater entering Port Jackson estuary to provide a rigorous data base for future remediation efforts. A conceptual model of transport and fate of heavy metals in stormwater entering Port Jackson estuary has also been developed to identify heavy metals, subcatchments and flow regimes requiring remediation, and to assist in designing remediation devices for optimum removal of heavy metals from stormwater. Modelling of stormwater using the Model for Urban Stormwater Improvement Conceptualisation (MUSIC) indicated that the average annual discharge of stormwater from the Port Jackson catchment was 215,307 ML. Average annual loadings of arsenic, cadmium, chromium, copper, nickel, lead and zinc in stormwater discharging to Port Jackson estuary were 0.8, 0.5, 1.7, 3.2, 1.1, 3.6 and 17.7 tonnes per year, although comparison to other studies in the catchment suggests these values may be underestimations of actual loadings by 1.3 to 10 times. The proportion of heavy metals discharged under low-flow conditions (<5mm of rainfall in 24 hours), medium-flow conditions (between 5 and 50mm in 24 hours), and high-flow conditions (>50 mm of rainfall in 24 hours) was 6.5%, 62.5% and 31%, respectively. The conceptual model indicates stormwater loadings of copper, lead and zinc pose a risk to the health of riverine and estuarine ecosystems in the catchment and these metals should be targeted for remediation. Stormwater channels which should be prioritised for remediation include the channels entering southern embayments west of Darling Harbour; Duck, Parramatta and Lane Cove Rivers; and the channels and rivers entering Neutral, Long and Sugarloaf Bays. Stormwater loadings of lead are predominantly associated with suspended particulates, whereas loadings of copper and zinc are equally partitioned between dissolved and particulate phases. Stormwater remediation strategies should target both dissolved and particulate phases to ensure effective removal of copper, lead and zinc. Research suggests heavy metals in stormwater discharged to the estuary under high-flow conditions are rapidly exported seaward and bypass the estuary. Preliminary research also suggests that under medium-flow conditions, particulate heavy metals bypass the embayments of Port Jackson and are deposited in the main channel. Once deposited in the main channel, particulate heavy metals are likely to be remobilised and removed from the estuary through multiple phases of resuspension. Although further research is required in this area, this preliminary research suggests remediation should target low-flow conditions. The findings of the current research could be used to identify appropriate remediation strategies for dissolved and particulate phase heavy metals in stormwater discharging to Port Jackson estuary. However, in designing stormwater remediation devices, consideration should also be given to the range of contaminants that may be present in stormwater entering Port Jackson estuary (including suspended solids, nutrients, pesticides and organics).
