FATORES DETERMINANTES DA MORTALIDADE DE MICRO E PEQUENAS FARMÁCIAS DA BAIXADA SANTISTA: sob o olhar do farmacista

Esse trabalho estudou o segmento farmacêutico de micro e pequenas farmácias da região da Baixada Santista, em relação aos fatores determinantes da mortalidade no segmento, sob o olhar dos proprietários e gestores das farmácias, visto que nos últimos anos o segmento vêm sofrendo um encolhimento, além da migração das farmácias de micro e pequeno porte para as zonas mais periféricas das cidades da região da Baixada Santista. A metodologia utilizada para a pesquisa foi qualitativa, através de uma pesquisa exploratória e bibliográfica, tendo como instrumento de coleta de dados entrevistas, com roteiro semi-estruturado, aplicado a gestores e proprietários de sete farmácias na região da Baixada Santista. Cinco delas em atividade e duas fechadas, nos municípios de Santos, São Vicente, Guarujá e Praia grande. A análise dos dados foi feita com base em categorias analíticas criadas a partir da literatura que embasa esse estudo, chegando a dois blocos de análise: um relacionado diretamente aos fatores mercadológicos das farmácias, e outro relacionado a fatores administrativos e de custo. A análise dos dados comprovou existir fatores determinantes para a mortalidade das micro e pequenas farmácias da região, separados em dois blocos. No bloco mercadológico, estão relacionados os fatores determinantes que afetam diretamente a parte comercial das micro e pequenas farmácias, como o crescimento das grandes redes de farmácias, programa Farmácia Popular e falta de poder de compra por parte das farmácias. No bloco administrativo e de custos, estão relacionados a deficiência na gestão empresarial, custos operacionais, tributação e problemas pessoais. Através dessa pesquisa se conclui que esses fatores determinantes têm enfraquecido o segmento de micro e pequenas farmácias, ocasionando a mortalidade de diversas farmácias, não poupando nem mesmo as tradicionais da região da Baixada Santista.

IT support for managing aircraft spares in a closed-loop supply chain

This paper reports on the development of elements of an e-supply chain management system for managing maintenance, repair and overhaul (MRO) relationships in the aerospace industry. A standard systems development methodology has been followed to produce a process model (i.e. the AMSCR model); an information model (i.e. business rules) and a computerised information management capability (i.e. automated optimisation). The proof of concept for this web-based MRO supply chain system has been established through the collaboration with a sample of the different types of supply chain members. The proven benefit is a reduction in the stock-holding costs for the whole supply chain whilst also minimising non-flying time of the aircraft that the supply chain supports. This type of system is now vital in an industry that has continuously decreasing profit margins, which in turn means pressure to reduce servicing times and increase the interval between maintenance actions.

Ultrashort pulse generation from diode laser devices

This thesis presents a detailed, experiment-based study of generation of ultrashort optical pulses from diode lasers. Simple and cost-effective techniques were used to generate high power, high quality optical short pulses at various wavelength windows. The major achievements presented in the thesis is summarised as follows. High power pulses generation is one of the major topics discussed in the thesis. Although gain switching is the simplest way for ultrashort pulse generation, it proves to be quite effective to deliver high energy pulses on condition that the pumping pulses with extremely fast rising time and high enough amplitude are applied on specially designed pulse generators. In the experiment on a grating-coupled surface emitting laser (GCSEL), peak power as high as 1W was achieved even when its spectral bandwidth was controlled within 0.2nm. Another experiment shows violet picosecond pulses with peak power as high as 7W was achieved when the intensive electrical pulses were applied on optimised DC bias to pump on InGaN violet diode laser. The physical mechanism of this phenomenon, as we considered, may attributed to the self-organised quantum dots structure in the laser. Control of pulse quality, including spectral quality and temporal profile, is an important issue for high power pulse generation. The ways to control pulse quality described in the thesis are also based on simple and effective techniques. For instance, GCSEL used in our experiment has a specially designed air-grating structure for out-coupling of optical signals; hence, a tiny flat aluminium mirror was placed closed to the grating section and resulted in a wavelength tuning range over 100nm and the best side band suppression ratio of 40dB. Self-seeding, as an effective technique for spectral control of pulsed lasers, was demonstrated for the first time in a violet diode laser. In addition, control of temporal profile of the pulse is demonstrated in an overdriven DFB laser. Wavelength tuneable fibre Bragg gratings were used to tailor the huge energy tail of the high power pulse. The whole system was compact and robust. The ultimate purpose of our study is to design a new family of compact ultrafast diode lasers. Some practical ideas of laser design based on gain-switched and Q-switched devices are also provided in the end.

Infection risk associated with a closed luer access device

The potential for microbial contamination associated with a recently developed needleless closed luer access device (CLAD) (Q-Syte™ Becton Dickinson, Sandy, UT, USA) was evaluated in vitro. Compression seals of 50 multiply activated Q-Syte devices were inoculated with Staphylococcus epidermidis NCTC 9865 in 25% (v/v) human blood and then disinfected with 70% (v/v) isopropyl alcohol followed by flushing with 0.9% (w/v) sterile saline. Forty-eight of 50 (96%) saline flushes passed through devices that had been activated up to a maximum of 70 times remained sterile. A further 25 Q-Syte CLADs that had undergone multiple activations were challenged with prefilled 0.9% (w/v) sterile saline syringes, the external luer tips of which had been inoculated with S. epidermidis NCTC 9865 prior to accessing the devices. None of the devices that had been accessed up to 70 times allowed passage of micro-organisms, despite challenge micro-organisms being detected on both the syringe tip after activation and the compression seals before decontamination. These findings suggest that the Q-Syte CLAD may be activated up to 70 times with no increased risk of microbial contamination within the fluid pathway. The device may also offer protection from the external surface of syringe tips contaminated with micro-organisms. © 2005 Hospital Infection Society. Published by Elsevier Ltd. All rights reserved.

Color categories: confirmation of the relativity hypothesis

The question of whether language affects our categorization of perceptual continua is of particular interest for the domain of color where constraints on categorization have been proposed both within the visual system and in the visual environment. Recent research (Roberson, Davies, & Davidoff, 2000; Roberson et al., in press) found substantial evidence of cognitive color differences between different language communities, but concerns remained as to how representative might be a tiny, extremely remote community. The present study replicates and extends previous findings using additional paradigms among a larger community in a different visual environment. Adult semi-nomadic tribesmen in Southern Africa carried out similarity judgments, short-term memory and long-term learning tasks. They showed different cognitive organization of color to both English and another language with the five color terms. Moreover, Categorical Perception effects were found to differ even between languages with broadly similar color categories. The results provide further evidence of the tight relationship between language and cognition.

The development of color categories in two languages: a longitudinal study

This study unites investigations into the linguistic relativity of color categories with research on children's category acquisition. Naming, comprehension, and memory for colors were tracked in 2 populations over a 3-year period. Children from a seminomadic equatorial African culture, whose language contains 5 color terms, were compared with a group of English children. Despite differences in visual environment, language, and education, they showed similar patterns of term acquisition. Both groups acquired color vocabulary slowly and with great individual variation. Those knowing no color terms made recognition errors based on perceptual distance, and the influence of naming on memory increased with age. An initial perceptually driven color continuum appears to be progressively organized into sets appropriate to each culture and language. PsycINFO Database Record (c) 2009 APA, all rights reserved
