Esta tese tem como ampla proposta apresentar evidências a respeito da situação de segurança alimentar mundial, já que o mundo enfrenta problemas graves e urgentes relacionados à insegurança alimentar. Para tanto, são apresentados cinco estudos que abordam tal temática. O primeiro estudo se propõe a investigar as exportações de feijão brasileiro, observando as condições de segurança alimentar de seus compradores. O segundo estudo busca discutir os perfis agrícolas das principais regiões da África, bem como a parceria estabelecida entre a África e o Brasil com intuído de fomentar a inovação na agricultura e o desenvolvimento econômico. O terceiro estudo busca identificar e analisar os principais padrões de abastecimento alimentar da população mundial, e, em seguida, relacioná-los com as respectivas condições de desnutrição de suas localidades. A hipótese é que existem padrões de suprimento específicos, geograficamente identificáveis, que estão associados com o desalinhamento nutricional de certas populações em maior grau do que outras. O quarto estudo investiga a situação e a tendência de insegurança alimentar em todo o mundo considerando suas principais regiões geográficas. O quinto estudo objetivou analisar o impacto de fatores sócio-econômicos e comportamentais sobre a situação obesogênica em todo o mundo. Para tanto, os estudos se baseiam em dados disponibilizados por entidades e órgão oficiais como FAO, WHO, UNSD, IBGE e Banco Mundial. Além disso, para a análise dos dados foram empregadas técnicas de estatísticas descritivas, análise do coeficiente de correlação (Pearson e Spearman), regressão linear (múltipla e simples), análise de cluster e análise fatorial. Também foram elaborados diagramas de dispersão e gráficos de séries temporais. Os resultados sugerem que os modelos de suprimento alimentar estão significativamente relacionados aos problemas de insegurança alimentar mundial. Também ficou evidenciado que algumas nações e regiões mundiais enfrentam gravidades severas de segurança alimentar, com tendências alarmantes de agravamento. Especificamente a região do sul da África apresenta aumento tanto de sobrepeso quando baixo peso infantil. Já os países do leste asiático apresentam os melhores indicadores de segurança alimentar. Também o estudo sugere que o Brasil tem potencial de auxiliar na promoção da segurança alimentar, tanto por meio da produção e suprimento de alimentos, como por meio de parcerias inovativas com regiões mais desfavorecidas como a África subsaariana. As implicações deste estudo abrangem o âmbito das políticas públicas, práticas privadas e elementos econômico-sociais. As evidências aqui apresentadas poderão auxiliar no desenvolvimento de iniciativas em prol da promoção da segurança alimentar mundial. Além disso, o papel do agronegócio Brasileiro como potencial atenuador da insegurança alimentar mundial é destacado, necessitando de uma articulação política e privada para seu desenvolvimento sustentável. / The wide proposal of this thesis is to present evidence about the situation of food security worldwide, since the world is facing severe and urgent problems related to this issue. Considering this finality, this thesis is composed by five studies addressing the food security worldwide issue. The first study aims to investigate the export of Brazilian dry-beans, observing the conditions of food security of importers. The second study aims to discuss the agricultural profiles of the main regions of Africa, as well as the partnership between Africa and Brazil established to foster innovation in agriculture and economic development. The third study seeks to identify and analyze the main food supply patterns of the world's population, and then relate them to their conditions of malnutrition in their localities. The hypothesis is that there are specific supply patterns, geographically identifiable, which are associated with nutritional misalignment of certain populations to a greater degree than others. The fourth study investigates the status and trend of food insecurity around the world considering its major geographic regions. The fifth study aimed to analyze the impact of socio-economic and behavioral factors on obesogenic situation worldwide. All five studies are based on data available at official organizations and institutions as FAO, WHO, UNSD, World Bank and IBGE. In addition, data analysis techniques complies descriptive statistics, correlation analysis (Pearson and Spearman), linear regression (simple and multiple), cluster analysis and factor analysis. Scatterplots and time series graphs were also elaborated. The main results suggest that food supply patterns are significantly related to the problems of global food insecurity. It was also found that some nations and world regions face severe severities of food security, with alarming trends of worsening. Specifically, Southern Africa region has increased prevalence of overweight and underweight children. The countries of Eastern Asia have the best indicators of food security, considering anthropometric indicators. The study also suggests that Brazil has the potential to assist the promotion of food security worldwide through the production and supply of food, and through innovative partnerships with poorer regions like sub-Saharan Africa. The implications of this study include the realm of public policy, private practices and economic-social elements. The evidence presented here may assist in developing initiatives for the promotion of world food security. Furthermore, the role of the Brazilian agribusiness as potential attenuator of food insecurity worldwide is highlighted, requiring political and private articulation for the sustainable development.

This is a study of how industries develop in regions that are industrially weak, exemplified by Norrbotten, the northernmost province of Sweden. Developing industries are represented by three companies manufacturing prefabricated wooden houses, situated in the municipalities Övertorneå, Kalix (Morjärv) and Älvsbyn in the interior of Norrbotten.For the period ending in 1918, the economy of Norrbotten is analysed in terms of staple theory. Thereafter, an analysis in dependency theoretic terms is judged to be more relevant. The communities in which the house factories are located are described similarly.Övertorneåand Mor j ärv are in the periphery of a peripheral region. There has never been any locally generated economic life of any importance. The house factory in the community first mentioned was established there in 1970 by AMS (The Swedish Labour Market Board). The other one was started by a local entrepreneur in the 1930's. It has changed hands several times, being incorporated into ever larger conglomerates. The third company studied was started by a local carpenter who still controls it. The factory is located in Älvsbyn, near Piteå, which has to be considered the center of the periphery.The integration of these three companies with other local firms, and their economic importance was studied in terms of their buying behavior. The method of investigation was a study of the internal records of the firms.All three of the companies showed that a decrease in the local and regional shares of their total purchases took place between the sample years studied. A comparison of the companies showed the Älvsby factory, the one locally initiated and controlled, to have by far more solid local and regional foundations than the other two. This could partly be explained by firm-related theories but the most important factor seemed to be the industrial tradition in the communities. Industrial tradition is a factor mostly determined by the position of a community in a dependency hierarchy, in part however, it is controllable by local decision-makers and individual entrepreneurs.Even for the company with the best local foundations, there was a drop in local and regional shares of purchases. The reason for this is the size of the company in relation to other local industries. The company has reached the limits of the capacity of the local community to support it. Such limits exist everywhere but their exact level depends on the status of the community and region they are in, the line of industry, the nature of ownership, etc.A series of implications for regional politics can be derived from the present study. Economic measures designed to improve weak industrial areas should be undertaken with utmost care in order not to damage existing local economy. Much greater efforts should be made to study the conditions of existing economic life and its potential for change, i.e. to study the historical development. / digitalisering@umu

As the demand for energy continues to increase around the world, more vessels used in the transport of energy, such as Liquid Natural Gas (LNG) and crude oil tankers are being built to transport energy to market overseas. The escort tug has been developed in order to assist in the safe transit of such vessels in confined waterways. Designed to apply emergency braking and steering forces to the stern of a tanker while underway, an escort tug features a hull shape that generates large hydrodynamic lift and drag forces when operating at high angles of attack, this is known as indirect mode. This escorting mode is highly effective at speeds 8 knots and above, often generating towline forces well in excess of bollard pull. Escort performance prediction is a vital aspect of the design of escort tugs. It is important to know a priori if a design will meet the necessary performance criteria. In the past, performance predictions have relied heavily on model testing and empirical methods. With the recent emergence of Computational Fluid Dynamics (CFD) as a commercially viable design tool for naval architects, extensive escort performance predictions can now be carried out more accurately in less time and at less cost than was previously possible. This thesis describes the methodology of a CFD based escort performance prediction method that is accurate and cost effective. / Graduate

1933年(昭和8年)日本因全球經濟大蕭條引發「昭和農業恐慌」，加上帝國內部米穀供應嚴重過剩，米價大幅滑落，促使日本政府加強米榖方面的各項統制措施。本文試圖由1933年開始至1945年日本戰敗為止，日本政府為因應米穀供應過剩或者不足所採取的各項統制措施，及其對殖民地臺灣所產生的影響。日本政府實施之米穀統制政策，對臺灣米穀生產造成影響者，如1933年實施的「米穀統制法」、1936年的「米穀自治管理法」、1939年於臺灣內部實施的「臺灣米穀移出管理令」、1942年7月1日施行的「食糧管理法臺灣施行令」、1943年底的「臺灣食糧管理令」、還有1944年年中推行的「米穀增產及供出獎勵相關特別措施」等。由這些米穀統制法令及措施，可以了解日本的臺灣總督府用盡一切方法，就是為了使其最重要的民生主食「稻米」的生產及供應，能達到「自給自足」的目標。臺灣，作為日本殖民帝國下的一員，為配合帝國整體米穀供需穩定，對於「看天吃飯」的米穀生產，悲願地追求其自足目標。臺灣蓬萊米生產的擴大與臺日米價間的互動，連帶影響臺灣糖價及其他農作物的生產，並可藉此了解日本與臺灣之間，因稻米生產而衍生出的統制生產架構。 / In 1933, the world economic recession (the Great Depression) caused the imperial Japan into the so called 「Showa Agricultural Panic」 and made the imperial internal rice supply overwhelmingly surplus. Those　made the price of rice in Japan at that time fallen considerably, prompting the Japanese government to strengthen the rice control policies.This article, from 1933 to 1945, tries to explain the impacts of the Japanese government's various rice control policies which responded to the rice oversupply or insufficient upon the colonial Taiwan. The rice control policies Japanese government implemented made great influence upon Taiwan's rice production, such as in 1933, the enactment of the "Rice Control Law" ; in 1936, the enactment of the " Rice Self-management Law " ; in 1939, only in Taiwan enacted, the" Taiwan Rice Shipment Administration Order " ; in July 1 1942," The Staple Food Control Act's Taiwan Enforcement Order ” ; the end of 1943, “ Taiwan's Staple Food Control Administration Order ”; and promulgated in mid-1944 “Special Measures on Enhancing Rice Production and Awarding Shipment ",etc.Through those rice control laws and measures, we can understand the Japanese rulers exhausted to make people's livelihood, the production and supply of the most important staple food "rice", could achieve the goal of “self-sufficiency ".Taiwan, as one part of the Japanese colonial Empire, had to cooperate with the whole Empire’s rice supply and demand as stable as possible. Regarding the rice production which depends on the weather, Taiwan like Japan vows to pursue the goal of “self-sufficiency” with the earnest wish. The expansion of production of the Taiwan Formosan rice (Penglai rice) and the interaction of rice prices between the Taiwan and Japan influenced the Taiwan's sugar price and the production of other crops. Therefore, we can understand the control production structure caused by the rice production between Japan and Taiwan.
