Analýza CSR problematiky vo vybranej firme / CSR Analysis in a Specific Company

Orlovská, Jana January 2012 (has links)
Today, globalization, new technologies and modernization bring a lot of negative influences on our environment and society we live in, compared to the positive effects they create. And that is the reason why so many companies are embarking on socially beneficial goals, rather than profit. The aim of the diploma thesis is to explore and evaluate a concept of corporate social responsibility at Rossmann. In the theoretical part of the thesis I familiarize the reader with corporate social responsibility, dealing with the main characteristics of the concept and actual situation in the Czech republic. The second chapter deals with the characteristics of Rossmann and its activities in the CSR field. The practical part consists of two parts. The first one focuses on internal and external analysis of the company`s environment with regards to CSR. The second practical part is concerned with the empirical research, that was realized by the questionnaire investigation. Following the gained knowledge I will answer the fundamental question: How is the corporate social responsibility part of the company strategy? I will propose measures that will lead to increasing awareness of CSR and the advantages that using CSR brings to the company more effectively.

Ekonomické dopady penzijních fondových pilířů - mezinárodní zkušenosti / The global reflection of private pension pillars and its economic impacts

Červenka, Michal January 2012 (has links)
The main addressed question of this thesis is whether international experiences indicate that private pension pillar contributes to the profitability and stability of pension system and economic development. Firstly, global private pension pillar is characterized. Its long term return is estimated from derived virtual portfolio. Following Aaron-Samuelson principle, it is calculated notional return of global public pension pillar. Comparing returns of both pillars, there is slightly higher return of private pension pillar, but considering variability, entailing risk, the public pension pillar becomes favorable. Moreover, combination of both pillar doesn't seem to be effective since both returns are well correlated. Next section of the thesis deals with economic effects of private pension pillar on labor market. Simple correlation doesn't proof a positive linking of private pension pillar's contribution magnitude and labor activity, expressed as an average annual working time of population in productivity age. Subsequent analysis of private pension pillar's outlook in selected countries illustrates unfulfilled expectations of participants in private pension pillars. Reflecting all particular findings, it wasn't confirmed that private pension pillars substantially contribute to profitability and stability of pension system and performance of economy.

Důchodová reforma v ČR a její pojetí se zaměřením na druhý pilíř / Pension reform in the Czech republic and its approach focused on second pillar

Dvořáková, Monika January 2013 (has links)
My diploma dissertation concerns the theoretical introduction of the retirement system, economic theories and the cause of the retirement reform in the first part. The second part represents the analysis of so-called small retirement reform and is focused on the retirement system since the beginning in 2013 with the accent to newly established retirement saving. The aim of my diploma dissertation is the evaluation of the existing functioning of the second pillar and the reasons of the low interest of the inhabitants. The comparison with the chosen states where the retirement saving already operates is a part of the second pillar analysis. Slovakia and Hungary are the European representatives with the similar schema of the retirement system and Chilean system is based on the fund financing. The opinion of the population was checked with the questioning. The pivotal part of my diploma dissertation and its main goal is the analysis of the second pillar accession availability from the age, income, family situation, investment strategy point of view and other criteria. The strategy with the low earning is suitable for the higher incomes only as resulted from the calculation. The more aggressive investment strategy with higher earning is convenient for the younger people with lower income and the older the more suitable access contingent on the higher income. As there is no interest in the second pillar participation the goal of my diploma dissertation is the proposal of alternative methods as investment or saving products of the bank institution for the old age security.

Komparace penzijních systémů visegrádské čtyřky se zaměřením na ČR / The comparison of pension systems in the Visegrád Group focused on the Czech Republic

Hlavová, Kristýna January 2013 (has links)
Visegrád countries were forced to adopt a widespread pension reform due to demographic facts. This reform led to the creation of the 2nd pillar. This thesis deals with this new funded pillar, which should facilitate the financing of the PAYG system (1st pillar). Using comparative analysis I reveal why all of Visegrád countries reduce 2nd pillar after several years of its functioning. The most common reason for this reducing was an effort to improve the unsatisfactory situation of public finances. The abolition of 2nd pillar actually leads to a certain improvement of public debt and deficit, but this positive effect is only short-term. More specifically I focus on the arguments of the Government for the abolition of the funded pillar in the Czech Republic, which I consider largely baseless. I also discuss the possible impacts of the reducing of the 2nd pillar. Currently, the countries of V4 try to save their pension systems using the 3rd pillars, however the current form of this supplementary pillar cannot provide a sufficient financing of the PAYG system.

No. of bitstreams: 1 caiomarceluspaislevasseur.pdf: 4546598 bytes, checksum: be57e1ab62ac45ae2f9ffe3e165c9e75 (MD5) Previous issue date: 2015-04-30 / CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Os sistemas de implantes osseointegráveis se apresentam em um ou mais componentes, e a correta inter-relação, passividade de assentamento e resistência biomecânica, definem a resistência / vulnerabilidade do mesmo frente aos fatores bacterianos e oclusais. Objetivo: Avaliar as deformações inerentes ao processamento laboratorial dos pilares calcináveis de corpo único para o sistema de implantes Cone Morse. Materiais e métodos: Utilizou-se 20 implantes Cone Morse da marca SIN, 10 componentes protéticos calcináveis e 10 não calcináveis. Após os processos laboratoriais, os conjuntos foram submetidos à Microscopia eletrônica de varredura (MEV) da interface pilar/implante, para análise qualitativa e quantitativa da desadaptação gerada. Os conjuntos foram levados a ciclos térmicos (1.000 ciclos) e de fadiga mecânica (500.000 ciclos) e novamente foi realizada a MEV. Os resultados foram comparados através de análise estatística de Mean-Whitmann. Resultados: O grupo de teste (G1) apresentou os maiores valores iniciais, com média de 34, 55 μm e 11,17 μm, para a subdivisões A (fundição) e B (aplicação de porcelana) respectivamente. A subdivisão B do grupo teste apresentou a maior alteração pós testes, com média de 19,28 μm de aumento da desadaptação protética. As subdivisões G1.A, G2.A, G2.B mostraram tendência à diminuição da desadaptação de -1,03 μm, - 1,64 μm, e -0,49 μm, respectivamente. Pilares Cone Morse não calcináveis apresentam-se com alta estabilidade e baixa taxa de desadaptações. Para o grupo teste pode-se afirmar que o processo de fundição nitidamente criou as maiores dilatações e desadaptações das estruturas. O processo de sinterização da porcelana em teste, criou uma redução da desadaptação medida, porém esta voltou a aumentar após os testes em laboratório. Para o grupo controle, houve a manutenção das taxas de desadaptações menores ao limite de 10 μm, e com tendência de redução após os testes. Conclusão: O pilar calcinável Cone Morse de corpo único mostrou-se como desfavorável quanto à biomecânica, e o processo de fundição gerou as maiores desadaptações. / The system of dental implants present in one or more components, and the correct interrelationship, settling and passive biomechanical strength, defining the strength / vulnerability of the same to the forward occlusal and bacterial factors.Objective: To evaluate the defects associated to laboratory processing of abutments of unique body to the system of Cone Morse implants. Methods: We used 20 Cone Morse implants SIN brand, prosthetic components 10 and 10 calcinable not calcinable. After the laboratory processes the sets were subjected to scanning electron microscopy (SEM) of the pillar / implant interface, for qualitative and quantitative analysis of the generated misfit. The samples were taken to alternated thermal cycles (1000 – 50 and 550) and mechanical fatigue (500,000 - 120 N/cm2) and again was carried out by SEM. The results were compared by statistical analysis Mean-Whitmann (P>0,05). Results: The test group (G1) showed the highest initial values, averaging 34.55 and 11.17 micrometres for subdivisions A (casting) and B (porcelain application) respectively. The B subdivision of the test group showed the greatest change after tests, averaging 19.28 mm of increasing prosthetic misfit. The G1.A subdivisions, G2.A, G2.B showed a tendency to decrease the mismatch of -1.03 micrometres - 1.64 micrometres and -0.49 micrometres respectively. Pillars Cone Morse calcinable not present with high stability and low rate misfits. For the test group it can be said that the casting process clearly created the largest expansion and mismatches of structures. The porcelain sintering process under test, created a reduction of the mismatch measure, however this increased again after the tests in the laboratory. For the control group, there was the maintenance of rates of minor mismatches to 10 micrometres limit, and with downward trend after the tests. Conclusion: Cone Morse castable pillars proved to be unfavorable on the biomechanics, and the casting process generated the biggest misfits.

Pillar[n]arene-based Porous and Smart Materials

Khalil Cruz, Laila Elizabeth 26 April 2022 (has links)
Pillar[n]arenes are a class of macrocycles with outstanding properties given by its electron rich and symmetric cavity, and facile functionalization that allows to tune its solubility and host-guest properties. In this work, the versatility of pillar[n]arenes for the design of porous materials is studied. Pillar[n]arenes are stable to guest removal, giving solvent-free phases and thus resulting in permanent porous structures. From simple ethyl pillar[5,6]arenes, nonporous adaptive crystals are obtained and studied for the recognition and separation of butanol isomers. The cavity size of the pillar[n]arene hosts and the linear or branched characteristic of the butanol isomers influences the assembly of the pillararene to selectively adsorb an isomer. Then, an A1/A2 benzaldehyde-functionalized pillar[5]arene is used as a building block for the synthesis of an imine porous organic cage, which would result in material with intrinsic and extrinsic porosity. Finally, a lipoic acid modified pillar[5]arene is implemented as ligand for nanoclusters, improving their stability. Taking advantage of the cavity of the pillar[5]arene, a host-guest complex is formed, enhancing the optical properties of nanoclusters.

Comparison of load-bearing system in steel / Jämförelse av stålstommar

Svensson, Simon January 2022 (has links)
In single storey industrial buildings, the most common material used for the load-bearingsystem is steel. The load bearing system can be designed in different ways. The two mostcommon load-bearing systems of steel industrial buildings are portal frame and thetruss/pillar-system. The benefit of using these systems is the possibility of having largespan structures. These systems have also a high load capacity in function of its weight.Geometrical parameters like width, height, length, and roof slope of the building effectsthe design and the selection of which load-bearing system will be more suitable.The purpose of this thesis is to compare the two systems in terms of weight of steel, priceand global warming potential (GWP) and to see how the load-bearing systems differ. Tofulfil the purpose, it is necessary to find the geometrical parameters to design an optimalportal frame system and use the same parameters in order to design the truss/pillarsystem. By using the same geometrical parameters, the two systems can be comparable.The results of this thesis show that the truss/pillar system has less weight, lower price andlower global warming potential than the portal frame.As conclusions of this parametrical study, it was seen that the truss/pillar system isperforming better than the portal frame system. In general, it is not possible to say that thetruss/pillar-system is better. This is because this thesis work did not consider amongstithers the bracing system, foundation, connections, mounting or fabrication. But it ispossible to say that the differences between the two systems are not major.

Sanctuary of the Man-made

Jönsson, Fredrik January 2018 (has links)
They seek to embrace and understand the complexity of the man-made. They live alongside one another in a cluster - reflecting, synthesizing, producing and celebrating. They created their spaces and hierarchies through the basic principles of the wall and the column. The Sanctuary of the Man-made is an exploration of elements through a narrative that aims for a deeper understanding of human built complexity.

A New Style of Simulation Model for Mining Systems

Schafrik, Steven J. 05 October 2001 (has links)
The algorithms for the mathematical modeling to predict productivity of underground room-and-pillar mining systems are well-known and documented. These algorithms consider the time-varying relationships between mining equipment for a given geometry of operations as well as other constraints. This study presents a newly developed, user-friendly visual simulation computer tool for the Windows environment. This tool can be easily customized and utilized by field engineers and will help mine operators plan the optimum mining sequence for different mine geometries and equipment layouts. Program output includes monitoring of shift data, equipment utilization indices, and so forth. The simulation technique can be used with any environment. Use of the system is demonstrated in different mining equipment configurations. Development and validation of the system was aided by the Peabody Group. / Master of Science
