Повний текст джерелаGlobaliseringen och det industriella jordbruket har möjliggjort för konsumenter i Sverige och andra västländer att få tillgång till matvaror till låga priser och från många olika delar av världen. Samtidigt har detta medfört ett högt pris i form av miljöförsämringar och ett stort beroende av utländsk jordbruksproduktion, samt av olja och andra råvaror som inte är förnybara. Resultatet har blivit ett livsmedelssystem med urholkad hållbarhet och ökad sårbarhet. Accelererande klimatförändringar och den kommande krisen i samband med oljetoppen manar till nyorientering och en övergång till ett mer lokalbaserat system. Denna fallstudie av Uppsala kommun har undersökt utsikterna att återknyta matproduktionen till lokala system. Resultaten omfattar både en studie av den nuvarande matproduktionen i Uppsala, vilken även inkluderade en enkätundersökning av kolonilotter, en studie av potentialen att öka matproduktionen på mark som idag inte används aktivt för det ändamålet, samt en analys av möjligheter och utmaningar för en lokal matproduktion i Uppsala. Enkätundersökningen visade att på kolonilotter med stugor användes ca tio procent av den totala ytan för matproduktion, medan motsvarande siffra för kolonilotter utan stugor var flera gånger högre, ca 65 procent. Den totala skörden för alla kommunala kolonilotter i Uppsala uppskattades till 90 ton grönsaker och 48 ton frukt och bär. För den totala matproduktionen från jordbruket, trädgårdsnäringen och fritidsodlingen gjordes beräkningar för fem olika kategorier: Spannmål, mejeriprodukter, ägg, kött samt grönsaker, frukt och bär, som tillsammans utgör ca 85 procent av den totala svenska matkonsumtionen. Den uppskattade försörjningsbalansen varierade starkt mellan olika kategorier, från 400 procent för spannmål till 20 procent för kött samt för grönsaker, frukt och bär. Osäkerheten kring det vetenskapliga underlaget gällande fritidsodlingen är dock stort, vilket gör att siffrorna för grönsaker, frukt och bär bör tolkas försiktigt. För ägg och mejeriprodukter var försörjningsbalansen 67 procent respektive 50 procent. Studien av obrukad mark visade att den största potentialen för en ökad matproduktion finns inom fritidsodlingen, som beräknades skulle kunna öka med 3.5 till 6 gånger. En övergång till full självförsörjning skulle dock kräva drastiska förändringar i konsumtionsvanorna mot säsongsbetonade grönsaker och frukt samt mindre nötkött till förmån för mer vegetabiliskt protein. Analysen av möjligheter och utmaningar för en återgång till en mer lokal matproduktion pekade på att de största fördelarna är den stora produktionskapaciteten inom jordbruket, den stora sammanlagda arealen privat trädgårdsmark som till stor del är outnyttjad för matproduktion, det ökande intresset för stadsodling bland befolkningen, positiva attityder till lokal mat bland konsumenter, och en relativt hög medvetenhet kring klimatförändringar och behovet av ett mer hållbart samhälle. Bland de viktigaste utmaningarna fanns den bristande ekonomiska lönsamheten inom yrkesodlingen, den centraliserade livsmedelsindustrin, obalansen inom jordbruksproduktionen, med överskott på spannmål och underskott på andra livsmedelsråvaror, ohållbara konsumtionsvanor, tendenser hos svenska kommunala tjänstemän att stödja exploatering av bördig mark, samt den låga graden av medvetenhet hos både befolkningen och beslutsfattarna kring oljetoppen och samhällets sårbarhet generellt.

Повний текст джерелаExcept in Stockholm, local public transport shows a declining trend in spite of an annual total subsidy from the County councils of 10 billion SEK. This is fair enough. Running local bus services in small and medium sized towns in accordance with welfare economic criteria implies among other things a pricing policy which requires subsidization just above 50%, which happens to be the same as the present degree of tax-financing. However, this is just a coincidence, and not a mark of optimality, because it is found that the structure of fares is clearly suboptimal. As regards investment policy it is furthermore confirmed by a questionnaire survey that neither the principals (the County councils) nor their agents (bus companies) use cost-benefit analysis (CBA) for the design of local public transport systems, so the purpose of the thesis is to demonstrate the potential improvements of public transport in small and medium sized towns run on the basis of welfare economics. The operationalization of the welfare economic foundations requires some theoretical reorientation in the particular case of local public transport. A fundamental division of the supply is made between the “merit goods” part of total supply and the “normal goods” part, where benefit is measured by the individual willingness-to-pay. In a case study of the bus transport system of Linköping a number of generally applicable minor improvements are found by the welfare economic approach, which aggregated to the national level would imply a total net benefit which more spectacular projects in the public transport sector rarely can present.

Повний текст джерелаThe aim of this work was to increase the damping in a high performance thermoplastic composite with the poly(ether ketone ketone) (PEKK) as polymer matrix. The passive vibration damping concept based on piezoelectric particles (sodium niobate, NaNbO3) and conductive particles (graphene and carbon black) was studied. Piezoelectric particles ensure the mechanic-electric transduction of the vibration. Conductive particles dissipate by Joule effect the electric charges generated by the piezoelectric particles within the polymer matrix. Presence of these two kinds of particles improves the dissipation of the mechanical energy by the local transduction-dissipation phenomena. This damping film was visco-constrained between composites plies. The different contributions of energy dissipation have been identified: the polymer viscoelasticity, the stick-slip at the particle/matrix interface, the shear induced by carbon fibers and the local transduction-dissipation. The latter phenomena has been demonstrated significantly through the study of mechanical behavior and dynamic response of the laminate composites. After the polarization step, the area under the dissipative shear modulus G'' of the mechanical relaxation mode α is increased by 18%, the hysteresis loop area from 16% to 34% and resonance mode amplitudes are decreased, up to 54% for the 2nd mode

Повний текст джерелаOver the past few years, the development of functional surfaces by chemical and/or topographical ways has shown an increasing interest. Significant advances have been made to optimize surface properties, including tribological properties, through the introduction of processes for the surface texturing at micro and nano scales. Chemical, mechanical and energetic approaches can be used to improve or control the friction and the wear of materials. The femtosecond laser stands out as one of the best methods for ablation, being able, under certain conditions, to generate periodic self-organized surface morphologies (sometimes multiscales) and called ripples. This technique known as laser surface texturing (LST), nowadays commonly used in tribology and applicable to a wide variety of materials, has many advantages including the texturing speeds and the quality of surface structures obtained. Currently, many fields such as the automobile industry and the biomedical sector use the laser surface texturing as a means of improving the tribological properties. Recently, a new generation of poly(ether ether ketone) (PEEK) polymer prostheses has emerged, arousing interest for tribological studies. The surface texturing of PEEK, as a biomedical material, by femtosecond laser, in order to improve its tribological performance, provides the general context of this thesis. This thesis first deals with the laser-PEEK interaction at the scale of a laser impact and then it focuses on the optimization of the surface texturing in order to control friction and reduce wear of a PEEK/PEEK tribosystem

Повний текст джерелаO modelo de desenvolvimento adotado no Brasil, e em especial no Estado do CearÃ, ainda està longe de ser a efetiva soluÃÃo dos problemas acumulados ao longo de sÃculos de colonizaÃÃo sÃcio-econÃmico-polÃtico-cultural. Ao contrÃrio, à ele a origem principal da pÃssima distribuiÃÃo de renda vigente em nosso paÃs, regiÃes e estados. Assim, faz-se necessÃrio uma nova reflexÃo sobre o real significado do desenvolvimento, partindo inicialmente do entendimento das potencialidades e necessidades locais de uma determinada regiÃo. Este à o conceito de desenvolvimento local integrado e sustentÃvel. Onde para a sua aplicaÃÃo à preciso mudar o foco do olhar econÃmico vigente, da visÃo tradicional capitalista, cujo cerne à o mero crescimento econÃmico, para uma nova visÃo humanitÃria, da atividade econÃmica: a economia solidÃria, onde o foco à o desenvolvimento humano. Conceito ainda em construÃÃo a economia solidÃria reflete, atravÃs dos seus princÃpios, a necessidade de uniÃo de esforÃos numa perspectiva oposta à concorrÃncia entre seres humanos. Utopia? Alguns assim a julgarÃo. Outros nela acreditarÃo e nela se engajarÃo, crendo ser possÃvel a construÃÃo de uma nova sociedade - mais justa e fraterna, superando o atual contexto sÃcioeconÃmico-polÃtico-cultural do Brasil. Uma das formas de operacionalizar o desenvolvimento local endÃgeno à organizar a atividade econÃmica de pequenos produtores rurais atravÃs de sistemas produtivos locais de modo a tornÃ-los sujeitos de suas prÃprias HistÃrias. Partindo deste princÃpio o presente trabalho contÃm um estudo de caso no municÃpio de Quixadà na regiÃo do sertÃo central do CearÃ. Teve-se como intuito elaborar uma estratÃgia de desenvolvimento com base em polÃticas que contribuam para o desenvolvimento de regiÃes precÃrias e subdesenvolvidas, utilizando-se como estratÃgia o desenvolvimento os sistemas produtivos locais solidÃrios, formados pelos atores locais a partir das suas potencialidades e dos recursos locais.
The development model adopted in Brazil, and especially in the State of CearÃ, is still far from being the effective solution to the problems accumulated along centuries of social, economical, political and cultural colonization. Instead, it is the main cause of the bad income distribution occurring in our country. Therefore, it is necessary to make a new reflection on the real meaning of development, by starting with the understanding of the local potentialities and needs of a certain region. This is the concept of integrated and sustainable local development. To apply that concept, it is necessary to change the focus of the current economical approach from the capitalist traditional vision, whose essence is only the economic growth, to a new humanitarian vision concerning the economic activity. That is the solidarity economy, in which the focus is the human development. Being a concept still under construction, the solidarity economy reflects, through its principles, the need for combining efforts in a view opposite to the competition among human beings. Is it a utopia? Some will judge it like that. Others will believe and engage in it, believing that it is possible to construct a new society, a fairer and fraternal one, overcoming the current socio, economical, political and cultural context of Brazil. One the ways to operationalize the endogenous local development is to organize the economic activity of small rural producers through local production systems so as to make them subject of their own histories. Based on that principle, the present work consists of a case study in the municipal district of QuixadÃ, in the central countryside of Cearà State. The objective was to formulate a development strategy based on policies that contribute to the development of precarious and underdeveloped areas, using as strategy the development of local solidarity production systems formed of local actors based on their potentialities and the local resources.

Повний текст джерелаNelle megastrutture in acciaio la saldatura è una tecnica di giunzione ampiamente utilizzata. Tuttavia, le saldature rappresentano delle discontinuità geometriche e introducono elevati gradienti tensionali locali che influiscono negativamente sulla resistenza a fatica dei componenti. Secondo la letteratura scientifica recente, le analisi di resistenza a fatica più avanzate si basano sugli stati di tensione o deformazione locali calcolati in prossimità dei punti singolari. Ciononostante, le normative vigenti mancano di fornire una guida reale su come eseguire tali stime della resistenza fatica: la maggior parte di esse non fa riferimento agli approcci locali e prevede l'impiego del metodo della tensione nominale. Tuttavia, non esistono raccomandazioni su come ottenere la tensione nominale mediante un modello agli elementi finiti ed è demandato alla capacità ingegneristica del progettista stabilire quale sia quella adeguata. In questo contesto, la presente tesi di dottorato, focalizzata sul rendere possibile la stima della resistenza a fatica delle grandi strutture in acciaio, è divisa in dieci capitoli. Scopo della tesi è sia fornire un contributo scientifico ad alcuni tra i più avanzati approcci locali per la stima della resistenza fatica, che sviluppare un metodo pienamente conforme alle normative vigenti, al fine di poter essere impiegato nel contesto industriale. Il primo capitolo rappresenta l'introduzione generale sul tema trattato, lo stato dell'arte in materia di progettazione a fatica delle strutture saldate e le motivazioni della presente ricerca. Nel secondo capitolo vengono introdotti gli approcci locali adottati e le loro basi teoriche: l'approccio basato sui fattori di intensificazione delle tensioni (NSIF), il criterio della densità di energia di deformazione (SED) e il metodo della tensione di picco (PSM). Il terzo capitolo riguarda la caratterizzazione a fatica dei coprigiunti saldati, tipicamente impiegati come rinforzo nelle travi da ponte, per i quali è stata evidenziata una non uniforme classificazione a fatica a livello normativo. Mediante l'impiego dell'approccio locale SED e adottando modelli agli elementi finiti sia bidimensionali che tridimensionali, sono stati isolati i parametri che influiscono sensibilmente la resistenza e proposte soluzioni ottimizzate rispetto a quelle fornite dalle normative. I dati sperimentali ottenuti testando a fatica quattro differenti soluzioni geometriche sono sintetizzati con successo in un'unica banda di dispersione in termini di SED, indipendentemente dalla geometria della saldatura. L'approccio locale SED e la relativa curva di progettazione si sono dimostrati quindi adatti a stimare la resistenza a fatica dei coprigiunti saldati in acciaio. Il quarto capitolo è incentrato sul calcolo numerico del SED. La principale criticità dell'approccio, rappresentata dalla necessità di uno specifico il volume di controllo localizzato all'apice di un intaglio strutturale (al piede e alla radice dei cordoni di saldatura, nel caso dei giunti saldati), entro il quale l'energia di deformazione deve essere calcolata e mediata, è superata mediante l'utilizzo di maglie di calcolo (mesh) rade e generate in maniera completamente automatica da un generico algoritmo di meshatura. La soluzione proposta e le relative limitazioni di applicabilità sono stati formalizzati. La robustezza in termini di insensibilità alla tipologia di mesh, alla sua raffinatezza e alla formulazione degli elementi finiti sono alcuni dei vantaggi provati. La generalità del metodo è dimostrata anche mediante alcune applicazioni pratiche con l'impiego di differenti software agli elementi finiti. Il quinto capitolo stabilisce un collegamento tra i campi di tensione locali, in prossimità del piede e della radice dei cordoni di saldatura, e le componenti di tensione nominale valutate ad una adeguata distanza dalla saldatura stessa. Nel capitolo viene fornita una relazione analitica tra tale distanza e lo spessore della piastra caricata; inoltre, viene presentato un criterio per stimare il valore del SED, sia al piede che alla radice dei cordoni di saldatura, e, a posteriori, i relativi NSIFs, come esplicita funzione delle componenti di tensione nominale (sollecitazione membranale, flessionale e tagliante). Tale metodo si presta all'automatizzazione e, quindi, a condurre l'enorme quantità di verifiche a fatica richieste per una complessa struttura saldata in acciaio. Tuttavia, l'attuale mancanza di conformità normativa degli approcci locali SED e NSIF rappresenta un possibile ostacolo nelle applicazioni industriali. Per questo motivo nel sesto capitolo viene proposto un metodo, conforme alle normative vigenti e alla letteratura scientifica, per modificare il classico approccio nominale, che tuttora è il metodo di riferimento ampiamente accettato e riconosciuto. Il problema metodologico della definizione di tensione nominale in un modello agli elementi finiti viene superato attraverso un approccio originale che tiene conto sia degli effetti membranali che di quelli di flessionali. Viene presentata una validazione sperimentale e vengono discusse le implicazioni nella progettazione a fatica delle grandi strutture in acciaio. I capitoli settimo e ottavo presentano un post-processore ad elementi finiti, sviluppato per automatizzare l'analisi della resistenza a fatica di una struttura di grandi dimensioni. Il post-processore è basato sul solutore ad elementi finiti Straus7® ed è compatibile con modelli di tipo shell per essere adatto ai grandi assiemi strutturali. Molte delle proposte illustrate nella presente tesi sono state quindi automatizzate: gli approcci locali SED e NSIF, il metodo della tensione nominale modificato e, infine, gli approcci classici basati sulla tensione nominale e di hot spot. È inoltre mostrato un ottimo accordo tra le analisi condotte "manualmente", sia attraverso approcci globali che locali, e quelle eseguite rapidamente utilizzando il post-processore, riscontrando generalmente un ottimo accordo tra la vita a fatica stimata mediante l'approccio locale SED e quella stimata attraverso il metodo della tensione nominale modificata. Il nono capitolo tratta la stima rapida dei fattori di intensificazione delle tensioni residue (R-NSIFs), conseguenti al processo di saldatura, utilizzando il PSM e il software agli elementi finiti dedicato Sysweld®. Innanzitutto, viene presentata la calibrazione del PSM in ambiente Sysweld®; quindi vengono illustrate alcune applicazioni pratiche. Infine, il decimo capitolo riporta alcune osservazioni conclusive di carattere generale e la discussione dei principali risultati ottenuti.

Повний текст джерелаIn this study correlations between Rocha pear quality attributes and the incidence of internal browning (IB) were performed in order to know the major factors which determine different susceptibility of the fruit. Fruits under study were previously stored in dynamic controlled atmosphere (four months) and from three geographical origins (west region). The fruit incidence of IB showed to be dependent on geographical production localization. Fruits from Mafra and Lourinhã with 28 and 43% of IB, respectively, versus Alcobaça, where no symptoms were detected (0% IB). Fruits from Alcobaça showed the highest contents of ascorbic acid (AA) (4,8 mg/100 g) and of total phenolic compounds (CFT) (111,0 mg CAE/100 g), with increases of 20% and 40%, respectively, in comparison to the others, representing these the most distinctive quality factors. It was found that fruits with more calcium content, lesser potassium content and higher antioxidant capacity are more resistant to IB. By other side, the symptoms incidence is bigger in advanced post-harvest ripeness stages and minor AA content. The effects of AA content of the fruit on IB incidence were inconclusive. However, in the fruit core tissues the presence of similar AA contents between fruits, with and without IB, along with significant differences in CFT, could suggest that phenolic compounds are involved as a stress response to internal browning disorders mechanisms. Full ripening capacity was achieved in 4 days (room temperature) regardless fruits origin. However, fruits with higher internal browning incidence showed lesser storage ability (5 C), as a fresh-cut product

Повний текст джерелаIn vivo electroporation (EP) is used as a strategy to improve the immune response induced by DNA vaccines. However, its local effect on the innate immune cells has not been fully described. We developed in vivo fluorescence imaging approaches to highlight the cell behavior in the site of vaccination in macaques. Our results show that the local EP not only increases the amount and the distribution of the vaccine antigen, but also induces the mobilization and migration of Langerhans cells. Furthermore, EP causes the recruitment of leukocytes into the skin and subcutaneous tissue and promotes the production of pro-inflammatory cytokines. These early events that result from the use of the EP as a delivery system for DNA vaccines, highlight its potential as a vaccine adjuvant

Повний текст джерелаConsidering two global observations in Central Europe of, firstly, the need for, and development of, sustainable and biological conservation practices for forest and/or woodland areas and, secondly, the lack of long-term fire history, an attempt has been made to reconstruct the fire and the forest history at several investigation sites in Germany. The overall data set gathered and analyzed has been used for on-site naturalness assessment. This latter notion is crucial for forest system conservation/restoration planning, considering the past human impact on forest dynamics. Also, in view of this past human impact on forest systems, which is well-documented for Central Europe, as occurring on a multi-millennium scale, an historical perspective perceptive that combined a long and short temporal scale of investigation was used.Nine investigation sites were selected, in order to include various and representative types of Central European forest. Therefore, the investigation sites were located in two main investigation areas. One is in Northern Germany (Schleswig-Holstein) and includes four investigation sites. The other is in Central Germany (Harz Mountains) and includes five investigation sites. Four main approaches were used. To assess the current state of the investigated site, forest stand characterization was undertaken (i.e. based on various forest attributes that concern stand structure and composition). Tree ring series were analyzed to provide insights about short-term forest tree population dynamics. Then, charcoal records from soil (combined with soil analysis) and peat sequences were qualitatively and quantitatively analyzed. These last two approaches also provide information about the past fire history. Forest current and short-term dynamics illustrated various levels of stand complexity, often corresponding to various levels of human impact that had been postulated. Eight mean site tree-ring chronologies, standardized in high and mid-frequency signal, spanning at a maximum of up to AD 1744 and at a minimum of up to AD 1923, were obtained. The insight, about the identification of events of growing changes and the correlated temporal and, if possible, spatial patterns, was discussed. Charcoal analysis provided a long-term insight about fire history. Based on 71 charcoal radiocarbon dates, it was shown on a macro-scale that there were two phases that had a greater frequency of fire - one during the transition from the late Pleistocene to the early Holocene, and one during the mid- and late Holocene. A strong human control during the most recent fire phase has been postulated. This is supported by on-site soil and peat charcoal record analysis, allowing one to point out the event of environmental changes (disturbances), at local scales. In the end, the on-site data from the various indicators were combined to assess the fire and forest history and the naturalness level of the investigated sites, based on past insights, thereby contributing to a better understanding of the present and helping to anticipate the future

Повний текст джерелаThe transport sector is facing a transition from combustion engine vehicles to electric vehicles. Through this action the carbon dioxide emissions in the transport sector can be reduced. The purpose of this study is to observe how an increased power use from electric vehicle charging (EVC) affects the local electricity grid in Gävle. The study also addresses how different charging techniques affect the electricity grid. The background of this study is to the increase awareness of the capacity of the electricity grid. There is a need from the electricity grid company to look over the impact on the grid from EVC. This could also be useful for others looking over the impact on the electricity grid from EVC. This is a hot topic and lots of other studies look over the different aspects of EVC. Previous studies also examine different types of charging techniques and how smart charging reduces the negative impact on the electricity grid. Smart charging is a way to adjust the EVC by regulating it after different parameters and connecting the entire electrical grid. This study simulates existing measured values of the low-voltage grid in Gävle and various types of EVC. This study examines the power use of existing measurement data as well as load current and voltage drops in the electricity grid with different load profiles in four different areas. Results from this study shot that EVC affects the electricity grid, to what extent depends on the type of charging technology used and the dimensions of the electricity grid. The study shows that electricity use in the area has power peaks in the afternoon and evening with residential customers, but power peaks tend to be in the middle of the day if there are industries in the area. EVC increase the load on the electricity grid, causes voltage drops and a few fuses in the grid to be triggered. Charging with 11 kW between 16:00-19:00 and charging with a power monitor of 13.8 kW create the greatest voltage drops and highest load on the grid. Charging without means of control affects the electricity grid the most but charging with a power monitor also creates problems. Charging with 5.5 kW between 23:00-06:00 as well as when only 50 % of all customers charge with 11 kW between 16:00-19:00 impacts the grid the least. Charging with low power during the night when the base load is at its lowest is the charging technology that is most favorable for the electricity grid. Results also show that the grid can handle a higher load of EVC in the near future if only some of the customers in the network start using electric vehicles.

In today''s developed society, the explosion in population accelerates the growth of high-rise buildings in urban terrains. However, limited by land resource, high-rise buildings tend to be constructed by means of lighter material and higher levels, which inevitably results in a sensitive feature to wind-excited response rather than earthquake. Therefore, to understand the dynamic behavior of a tall building under wind loadings is attracting more and more concerns. Interference effect between any two neighboring buildings is especially focused in an urban area. The complex phenomenon may be triggered by many factors, such as surrounding flow characteristics, geometric appearance of buildings, relative positions of neighboring buildings, wind attack angles, etc. Many publications regarding this phenomenon have been carried out in domestic or overseas journals and reports. Generally speaking from the literature, such complicated phenomenon cannot be simply linearly superposed one by one. The present study was conducted to idealize the sources of interference effect and easy to investigate. By means of wind pressure measurement, a square prism model with aspect ratio 6 in a suburban turbulent boundary layer flow (α=0.24) was utilized as a principal building. Meanwhile another identical square prism model made by Balsa wood was utilized as interfering building and installed in several interfering positions. Instantaneous pressures over the principal building''s surface were recorded by at least 90 runs. Each run represents a 10-minute record in full scale. By normalized to velocity pressure at roof top, pressure coefficients were calculated and the maximum and minimum values were found. Based on extreme value theory, the Gumbel and Weibull distribution types were identified for different pressure tap positions due to different flow conditions. Then the design for cladding was briefly introduced. Experiment results showed that the maximum wind pressure coefficient was occurred in (x/B,y/B) = (3,3) position, representing that significant interference effects in the oblique configuration. The minimum pressure coefficient was found when the interfering building is in the upstream (y/B = 0). However, in this research, only the range between x/B = -3 ~ 3 and y/B = 0 ~ 3 were examined, the discussion on extreme values may be limited and the greater effect could occur outside the experiment range.

The Executive Yuan has organized a one-of-a-kind and value-added cultural creative industry with such local features as OTOP (one town one product program) in various parts of Taiwan to train local talents and develop industries of local specialties in the hopes of driving business and employment opportunities. For example, Changhua County features small and medium-sized enterprises that play an important role in the developing the regional economy. While the coastal areas of Xianxi primarily features oyster farmers who raise and sell their own products, the cultivation of pearls has gradually declined due to competition of other products from other townships, and the lack of funding and sales platforms have resulted in a non-benign cycle. This study focuses on creative packaging design that integrates the culture and humanity of Xianxi Township in Changhua County, with the theme of the oyster pearl. Then, we adopt the evaluation grid method (EGM) to explore the local style of the theme-based oyster-raising industry in order to analyze and encourage the four major primal attractive factors of packaging design, local specialties, local association, and fresh ingredients, as well as six specific attractive factors and nine abstract attractive factors. In this study, we used figurative graphics to compare old oyster farmers at the production end and fresh oysters at the consumption end as the primary vision, using such abstract graphics as totemized waves and windmill backgrounds as the creative theme. Doing so has rendered a new artistic sentiment from the perspective of this research, helping to demonstrate oyster pearl packaging in another way. Since the scene of thee two pictures, which greatly differ from each other as realism versus totem, we expect to establish a new creative concept. Furthermore, appreciating consumer preferences and satisfaction can help graphic designers integrate such consumer opinions and references in their creations with regard to the styles for local industry.

Повний текст джерелаWithin the current cultural and social context in which the economic and financial crisis of public administration is firmly rooted in the effects of climate change, international environmental policies and the emergence of new technologies, an innovative methodology, that analyzes energy planning (regional, district, and urban) at different scales, has been investigated. Regional (Regional Energy and Environmental Plans - PEAR), district (Pact of Islands) and urban/metropolitan (Sustainable Energy and Climate Action Plans - SECAP) energy plans have been analyzed by identifying opportunities and critical issues. The methodology identified has allowed to introduce and coordinate the proper integration of renewable sources (RES) and emission (GHG) reduction policies in the transport sector. In this context, a territorial planning and management effort, starting from the regional and national planning (PEAR), will have to relate more to the participatory push, which in the footsteps of Community policies is animating the energy discipline of the communities in particular through the instrument of the Action Plan for Sustainable Energy and Climate. The opportunity offered will enable the development of multi-level instruments (regional but declinable at the district and urban level), SECAPs to improve and adapt to each other through a comprehensive policy on energy planning . The vehicle will be to develop an integrated tool able to harmonize the SACAPs to promote distributed RES based generation at multi-scalar level.
