Industrial practice in technology planning - Implications for a useful tool catalogue for technology management

A survey on technology planning and its implications for a useful tool catalogue for technology management was conducted. The survey provided a picture of technology planning, across a broad range of company size, manufacturing type and sector. It was concluded from the findings that technology planning is an important business activity across industry sectors and company types, driven increasing competition, market requirements and regulation technology change. The process technology roadmapping was used to support technology strategy and planning and could be useful way of structuring both the use of tools in a company and a tool catalogue.

沈阳城市森林生态系统健康与管理研究

本文系统研究了沈阳城市森林的布局与结构、城市森林功能、城市森林病虫害发生与树木健康状况和城市自然资源与社会经济状况等指标对沈阳城市森林生态系统健康与管理的影响。同时一，采用2种生态系统健康评价方法对沈阳城市森林生态系统健康状况进行了评价，并提出了沈阳城市森林生态系统健康管理的对策。研究结果如下：1、截至2004年末，沈阳城市森林植被覆盖率已经达到35％，城市森林林地分布基本合理，但需要进一步加强道路林地、居住区林地和城郊大面积生态林建设。2、沈阳城市森林以乔木为主，乔灌株数比为1.7：1，乔灌的覆盖度比约为7:1。3、沈阳城市森林不同类型林地中植物组成不同。公园林地中有74个属，137个种（变种）；庭院林地中有53个属，104个种（变种）；居住区林地中有45个属，81个种（变种）；道路林地中有43个属，94个种（变种）；运河风景林地中有75个属，142个种（变种）；棋盘山风景林地中有48个属，118个种（变种）。4、公园林地、庭院林地、居住区林地、道路林地和运河风景林地的Shannon一Wiener多样性指数分别为2.78、3.05、3.15、3.18和3.18，均匀度指数分别为0.56、0.66、0.72、0.70和0.64。除了棋盘山风景林地外，沈阳城市森林中栽植总量超过乔木总量5％的乔木树种有7个属，分别为李、柳树、杨树、桧柏、榆树、槐树和银杏，7种树木总量达到了全部乔木总量的82.09％；栽植总量超过灌木总量5％的灌木树种也有7个属，分别为水腊、丁香、李属，小聚、玫瑰、忍冬和连翘，7个属灌木总量达到了全部灌木总量的87.92％。5、公园林地、庭院林地、道路林地和防护林地中OBH＜20cm、20cm＜DBH＜60cm和DBH＞60cm树木的比例分别为：57.9％、40.0％、2.1％，49.2％、47.8％、3.0％，65.3％、33.1％、1.6％和64.6％、34.9％、0.5％，表明沈阳城市森林树木的规格总体上偏小。6、经样方调查和CITYgreen模型计算，沈阳城市森林的生态效益约2.0亿USD／yr.。公园林地、庭院林地和风景林地的景观指标相对较高；道路林地和居住区林地的景观效果一般；防护林地的景观效果较差。7、目前已经发现的沈阳城市森林病害约600余种，虫害约700余种，其中杨树主要病虫害39种，柳树的主要病虫害有33种，榆树和槐树的主要病虫害均为，1种。杨柳树腐烂病、光肩星天牛、天幕毛虫、桃红颈天牛和美国白蛾等是近10年来沈阳城市森林中普遍发生和造成严重危害的主要病虫害。沈阳城市森林主要树木的平均健康指数为2.68，处于一般健康状态。8、沈阳城市森林的土壤和水资源状况均不利于树木的健康生长，沈阳的社会经济发展也有待于进一步提高。9、经过生物指示物法（光肩星天牛为生物指示物）、专家权重法、公众问卷调查和对比研究，沈阳城市森林生态系统总体上处于亚健康状态。10、通过对沈阳城市森林资源、管理状况的调查研究和健康状况的评价，本文提出了沈阳城市森林生态系统健康管理的对策，包括合理规划沈阳城市森林林地布局，增加道路林地、居住区林地和城郊林地的面积和植被覆盖率；调整树木种类组成，避免单一或少数树种的大量栽植，提高生物多样性水平；保护大树和古树；增加城市森林管理资金的投入；应用先进技术，采取科学的病虫害防治和植物养护方法，促进树木的健康生长等。This project systematically studied the urban forest ecosystem health and management in Shenyang. The study explored factors, such as urban forest structure, distribution, pests, aesthetic value, ecological benefit, natural resources and socieo-economic status, that affecting the urban forest ecosystem health and management. Two methods were used to evaluate the ecosystem health. This project also proposed Shenyang's urban forest ecosystem health management strategies. The research results can be summarized as follows: 1. As of the end of 2004, urban forest coverage in Shenyang is about 35%, and is in relatively even patch distribution pattern. However, the street trees and roadside forest patches, residential block forest patches should be enhanced. 2. Trees are the major component of the Shenyang s urban forest, followed by shrubs. The quantity ratio of tree to shrub is about 1.7:1, and the coverage ratio of trees to shrub is about 7:1. 3. Species composition varies by location. There are 74 genera, 137 species (including varieties) in the public parks; 53 genera, 104 species (and var.) in the green spaces of the institution (including school), factory, and company; 45 genera, 81 species (var.) in residential blocks; 43 genera, 94 species (var.) in streets and roadside forest patches; 75 genera, 142 species (var.) in the Canal landscape forest patches; 48 genera, 118 species (var.) in the Qipan Mountain recreation forest. 4. The Shannon-Woener indices varies in parks, in institution, factory, and company yards, in streets and roadside forest patches, in residential blocks.there are 2.78, 3.05, 3.18, 3.15, 3.18, respectively; and the evenness indices are 0.56, 0.66, 0.70, 0.72, 0.64, respectively. Besides the Qipan Mountain forest patches, trees of 7 genera, Prunus spp., Salix spp., Populus spp., Sabina spp., Ulmus spp., Robinia spp. and Ginkgo biloba are of more than 5% the total urban trees, respectively. In fact, trees from these 7 genera are about 82% of all trees in Shenyang's urban forests. In terms of shrubs, species of 7 genera, Ligustrum spp., Syringa spp., Prunus spp., Berberis spp., Rosa spp., Lonicera spp., and Forsythia spp. are more than 5% the total urban shrubs, respectively. 88% of all the shrubs in Shenyang s urban forest are from these 7 genera. 5. The diameter class of DBH<20cm, 20cmand DBH>60cm of trees in parks, in institution, factory, and company yards, in in streets and roadside forests, and in protective forests are 57.9%, 40.0%, 2.1%; 49.2%, 47.8%, 3.0%; 65.3%, 33.1%, 1.6%; and 64.6%, 34.9%, 0.5%, respectively. The result indicated that the DBH is relatively small in Shenyang s urban forests. 6. Using random plots sampling and CITYgreen model calculation, the ecological benefit of Shenyang's urban is about 0.2 billion US dollars per year. The aesthetic value of parks, institution and company yards, and scenary forest patches is relative high; however, the aesthetic value of protective forest patches is low. 7. There are more than 600 types of diseases and more than 700 kinds of insects in Shenyang's urban forest. Among them, Populus spp., Salix spp., Ulmus spp. and Robinia spp., are attached mainly by 39, 33, 11, and 11, difference types of pests respectively. The rot disease of the Populus spp. and Salix spp., and the insects such as, Anoplophora glabripennis, Malacosoma neustria, Aromia bungii, and Hyphantria cunea are major pests in Shenyang s urban forest for the past 10 years. The trees health condition is relatively poor by having the average health index of 2.68 for major species. 8. The urban soil and water resource are not favorable to tree's growth in Shenyang, and so is the socieo-economic status. 9. Through using bio-indicator, professional and public evaluation, and comparision with other urban forests, it can be concluded that the status of Shenyang s urban forest is not very healthy in general. 10. To improve the urban forest ecosystem health in Shenyang, a better urban forest design need to be implemented to enhance the area and vegetation coverage of the street and roadside forests, the residential block forests, and the surburb forest Species biodiversity need to be enhanced by adjust the species composition of urban forest trees to reduce the single or several tree species populations and to plant more varieties. A better fundings for urban forest health management need to be budgeted. Advanced technologies in tree care and scientific measures to control pests need to be adopted to prove better care for plants and to keep trees grow healthfully.

制造系统控制结构现状和发展——从集中结构到动态结构

系统的决策控制活动依赖于系统内部的控制结构，制造系统的控制结构是先进制造与自动化领域的重要研究课题。制造系统的控制结构与计算机技术、生产设备自动化水平及制造模式等因素有关。早期的制造系统采用集中控制结构，而柔性制造系统和计算机集成制造系统多采用递阶控制结构。目前制造业已进入一个新时代，传统生产模式和企业结构无法适应不可预测的激烈的环境变化。因此，未来制造系统需要具备快速变化能力的动态控制结构

Creating advantage in peripheral regions: The role of publicly funded R&D centres

Regional investment in R&D, technological development and innovation is perceived as being strongly associated with productivity, growth and sustained international competitiveness. One policy instrument by which policy makers have attempted to create regional advantage has been the establishment of publicly funded research centres (PRCs). In this paper we develop a logic model for this type of regional intervention and examine the outputs and longer-term outcomes from a group of (18) publicly funded R&D centres. Our results suggest some positive regional impacts but also identify significant differences in terms of innovation, additionality and sustainability between university-based and company-based PRCs. University-based PRCs have higher levels of short-term additionality, demonstrate higher levels of organisational innovation but prove less sustainable. Company-based PRCs demonstrate more partial additionality in the short-term but ultimately prove more sustainable.

Government Influence on the Construction Industry during the Economic Recession 2007 - 2013

Due to the high degree of international and economic integration across the globe, the 2007 global financial crisis quickly spread, causing recessions and widespread credit restrictions in advanced nations. During recessions, economic fluctuations cause dramatic changes to the market structure of industries, in particular, that of the construction sector. These structural changes can be further influenced by government strategies and policies; which if used incorrectly, can serve to fuel and exacerbate downturns. In contrasting form, during an economic recession, government strategies and policies can also be used to aid in exiting such economic turbulence. From an extensive review of literature it became apparent that very little research offered a comprehensive and systematic overview of Irish and UK construction related government policies and strategies adopted during recessions; hence the emergence of this topic. As part of an ongoing research PhD, the purpose of this paper is to collate and group Irish and UK Government strategies and policies adopted for the construction sector during the recession period 2007-2013; resulting in the establishment of a construction industry development framework and a taxonomic framework. The results reveal serious problems with the national strategic plan for the Irish construction industry, given that there is no overseeing body or target dates for implementation of the proposed actions. Furthermore, both countries failed to prioritize the proposed key actions within their strategic plans. The findings of this paper can be applied in the context of the construction sector to address shortcomings in the respective sub-sectors, while also aiding policy makers and company executives in mapping out future strategic milestones.

Application of disturbance management principles in fresh food supply chains

The desire for more robust supply chains has led to a growth in theoretical and practical interest in the application of both preventive and impact reductive disturbance management principles. This application should ultimately lead to less vulnerable and more competitive supply chains. Based on the extant literature we identify fresh food supply chain's contextual factors (products, processes, supply chain networks and supply chain business environment) and their corresponding characteristics, as well as the main disturbance management principles used. To analyse their influence on the selection and application of disturbance management principles in fresh food supply chains we conducted three case studies. In each case we collected data on the relevant contextual factors, disturbance management principles applied and company background. As an underlying methodology, we first conduct within-case analysis and then expand the analyses to a cross-case context. Based on the findings from these case studies, propositions are built concerning the nature of contextual factors and their characteristics, and their influence on the selection and application of disturbance management principles in fresh food supply chains. Our main findings are related to the identification of contextual characteristics of fresh food supply chains that are either critical vulnerability sources, critical enablers or conditionals and as such require, facilitate or condition selection and application of disturbance management principles.

Relatório de estágio realizado por: Tiago André Nogueira da Cruz Trabalho orientado pela Mestre Célia Sousa

Estudo e Acompanhamento de Projeto de Estabilidade

O trabalho foi desenvolvido na empresa Masterprojetos – soluções integradas, através da elaboração e desenvolvimento do projeto de estabilidade de um edifício de cinco pisos, em que um deles se encontra enterrado. Este edifício incorpora um bloco de habitação multifamiliar e um bloco de habitação unifamiliar e comércio. Tanto o edifício como a empresa estão localizados no Peso da Régua. O trabalho pode-se dividir em duas partes: Numa primeira parte estão descritas as funções desempenhadas e contextualizada a metodologia de trabalho. Nesta parte está ainda descrita a ferramenta de trabalho Cypecad, a qual não houve oportunidade de aprender a usar durante o meu percurso académico e desenvolveu-se capacidades de maneira autodidata. São ainda referidos alguns softwares disponíveis no mercado, para o mesmo ramo de atividade. Numa segunda parte encontram-se descritos os pressupostos considerados no pré-dimensionamento do edifício assim como os elementos utilizados para a formulação do modelo de cálculo. Estão ainda feitas algumas verificações analíticas para a validação do modelo tido em conta para o dimensionamento. Estabeleceu-se também uma comparação entre as soluções obtidas através do software Cypecad e através do cálculo analítico para uma laje maciça. No final estão descritas as conclusões que foram obtidas, das quais se salientam a atenção que é necessário ter, quando se utiliza softwares de cálculo automático, quanto à introdução de dados e soluções que se obtêm , assim como a poupança de tempo que este tipo de ferramenta proporciona. É de referir também neste ponto as oportunidades que o estágio me proporcionou, como a visita de alguns locais de obras, as atividades de medição e orçamento de obra e acompanhamento de projetos de outras especialidades como redes prediais, térmica, acústica e ITED (infra-estruturas de Telecomunicações em Edifícios).
