A gestão pedagógica no seio de uma instituição o caso do CAUÉ – Coral Alentejana da Universidade de Évora

Da criação, em 2004, da Secção Pedagógica do Coral Alentejano da Universidade de Évora, resultou a necessidade de encontrar um quadro organizacional que articulasse a participação dos(as) estudantes Universitários(as) (coralistas ou não), com as atividades próprias de um coral e com a extensão destas às escolas básicas. Desta forma, pretende-se promover o cante alentejano como ponto de partida e de chegada, no desenho e concretização curricular dos projetos educacionais. Assim sendo, surgiu a figura do Gestor Pedagógico concretizada, formalizada e legitimada, através da aprovação de um projeto de Estágio profissional, por parte do Instituto de Emprego e Formação Profissional. A comunicação que se apresenta descreve a atividade desenvolvida pela Gestora Pedagógica do Coral Alentejano da Universidade de Évora.

International workshop on "Different survey methods for coral reef fish, including methods based on underwater video"

In September 2013, staff from the University of the South Pacific (USP) Honiara campus, the Secretariat of the Pacific Community (SPC) and IFREMER (UR LEADNC, AMBIO project) in New Caledonia, and the French Institute for Pacific Coral Reefs (IRCP) in Moorea, French Polynesia, co-facilitated a workshop entitled “Different survey methods of coral reef fish, including the methods based on underwater video”. The workshop was attended by students from USP, NGO and fisheries officers. They were trained to several underwater visual census techniques and to the STAVIRO video-based technique, including both field work and data analysis.

Auditoría de sistemas al cumplimiento de los requerimientos 7, 8, 9 de la norma PCIDSS aplicada a Coral Hipermercado, Racar plaza con corte a Junio de 2015

Coral Hipermercado GO es una empresa dedicada a la comercialización de diversos productos de consumo masivo. Debido a la demanda que mantienen y el nivel de transacciones que realizan en ventas diariamente, de sus clientes ofrece diversas formas de pago entre ellas las tarjetas de pago, mismas que por la actual situación del auge de los sistemas informáticos y de la necesidad de la seguridad de los datos ante actos maliciosos las marcas de tarjetas de crédito han visto necesaria la implementación obligatoria (tanto en comercios como en las entidades intermediarias) de la Normativa PCI DSS. De esta manera, el servicio que brindan a los tarjetahabientes a más de ser mejorado, sea seguro en todas sus instancias. A través de nuestra investigación se obtuvo conocimiento de que la empresa Coral Hipermercado GO no ha realizado anteriormente una auditoria de la Normativa PCI DSS, por lo que la implementación de la Normativa podría no ser completa o apropiada, las políticas de la empresa pueden no contener los procesos y procedimientos que se deben llevar a cabo, haciendo que la seguridad de accesos a los datos de los titulares de tarjetas se vean vulnerables, de igual manera el manejo de las autenticaciones y la infraestructura de la seguridad física, misma que permite el resguardo de los equipos y por ende de la información. Se observó en la auditoría realizada a los requerimientos 7, 8, 9 de la Normativa PCI DSS que la misma no ha sido socializada en su totalidad, existen falencias en su implementación ya que el uso de las autenticaciones, accesos a los datos y seguridad física no son correctos, viéndose expuesta la información de los datos de los titulares de tarjetas de pago y la posibilidad de incurrir en pérdidas debido a probables actos maliciosos que se podrían encontrar expuestos en un futuro. Es imperativo mencionar que la norma ayudara al cumplimiento de los objetivos siempre y cuando se logren disminuir las falencias de su implementación o caso contrario se procederá a dar las recomendaciones necesarias respecto a los problemas encontrados para posteriores correcciones de forma que se mejore la gestión de la empresa.

Antibacterial and cytotoxic properties of isoprenoids from the red sea soft coral, Lobophytum sp

Purpose: To evaluate the antibacterial and cytotoxic activities of the secondary metabolites of Lobophytum sp. Methods: Maceration with methanol: chloroform (1:1) was applied to extract the coral material. Chromatographic and spectroscopic techniques were employed for fractionation, isolation and elucidation of pure compounds. Antibacterial activities were performed by well diffusion method against three Gram-positive and four Gram-negative bacteria. Brine shrimp lethality test was employed to predict toxicity, while antitumor activity were tested by 3-(4, 5-dimethylthiazol-2-yl)-2, 5- diphenyltetrazolium bromide (MTT) method against Ehrlich carcinoma cells. Results: Four sesquiterpenes, one cembranoid type diterpenes and two steroids were isolated. 1 exhibited significant antibacterial activity against four tested bacteria (P. aeruginosa, S. aureus, S. epidermis, and S. pneumonia) with MIC value of 15 μg/mL. Moreover, 1 showed high diameter zone of inhibition ranging from 16 - 18 mm against test bacteria. Compounds 4 and 5 displayed moderate antibacterial activity against all test bacteria with inhibition zone diameter (IZD) ranging from 11 – 15 mm and MIC values of 30 μg/mL. 2, 3, 6 and 7 exhibited weak antibacterial activity (IZD, 7 - 11 mm; MIC ≥ 30 μg/mL). In addition, only diterpene compound (4) showed high toxicity against A. Salina and antitumor activity against Erhlich carcinoma cells with the LD50 of 25 and 50 μg/mL, respectively. Conclusion: This study reveals the strong antibacterial activity of sesquiterpene alismol (1) and the potential antibacterial and antitumor activity of cembranoid type diterpene, cembrene A (4).

Ecologia reprodutiva do peixe-donzela, Stegastes fuscus cuvier, 1830 (osteichthyes: pomacentridae) em arrecifes rochosos da praia de Búzios, Rio Grande do Norte, Brasil

The reproductive ecology of fish plays a key role both for rational exploitation methods and for protective measures of natural stocks. The purpose of this study was to analyze the reproductive aspects of the damsel-fish, Stegastes fuscus, during October 2004 to September 2005, in the coastal rocky reefs of Búzios Beach, Nísia Floresta, RN. Fish were captured using hooks and hand nets, during low tide. Reproduction was determined using sexual ratio, mean length of first maturation (L50), absolute fecundity and macroscopic characteristics of gonads. The following parameters were related to gonadosomatic index (GSI): condition factor (CF), hepatosomatic index (HSI), rain fall and temperature. In relation to sex distribution, it was observed that 78% were females and 22% were males. The L50 was 6.2 cm for females and 7.0 for males. Average fecundity was 6832 oocytes. Results showed that S. fuscus had better body condition in the months prior to spawning, particularly during initial and intermediate stages of maturation. Five stages of gonadal maturation were identified through macroscopic analysis: immature, in maturation, mature, spent and resting. The HSI was inversely related to the GSI. This was possibly due to the reproductive cycle of this species which was associated to the dry period of this region. During this period, low rain fall and high temperatures provide an propitious reproductive condition for the study species

Investigating Stakeholders’ Preferences for Coral Reef Research Funding in Florida

Abstract: Heavily used and highly valuable, the Florida Reef is one of the world's most threatened ecosystems. Stakeholders from a densely urbanized coastal region in proximity to the reef system recognize its degradation, but their comprehension of climate change and commitment to pay for sustainable management and research funding have been opaque. With an emphasis on recreational anglers, residential stakeholders were surveyed online about their marine activities, perceptions of resources and threats, and willingness to pay (WTP) for dedicated coral reef research funding in Florida. The majority of stakeholders are wealthy, well educated, and politically independent. Supermajorities favored the two scenarios of taxation for a Florida Coral Reef Research Fund, and the scenario with matching federal funds earned higher support. In regression analyses, several factors emerged as significant contributors to stakeholders’ preferences, and the four recurring factors in extended models were prioritizing the environment over the economy, donating to environmental causes, concern about coral reefs, and concern about climate change, with the latter indicating a recent shift of opinion. Status in terms of income and education were found insignificant, and surprisingly income was negatively correlated with WTP. Perceptions through lenses of environmental and emotional attachments appear to overwhelm conventional status-based factors. Applied statewide, the first scenario's extrapolated WTP (based on a sales tax rate of 2.9%) would generate $675 million annually, and the extrapolated WTP under the second scenario, with matching federal funds (based on a sales tax rate of 3.0%) would generate $1.4 billion. Keywords: willingness to pay, coral reef research, taxation, climate change, stakeholder, perceptions, Florida Reef, recreational fishing, anglers

Quorum Sensing and Microbial Interactions in Coral Black Band Disease and Coral-Associated Bacteria

The black band disease (BBD) microbial consortium often causes mortality of reef-building corals. Microbial chemical interactions (i.e., quorum sensing (QS) and antimicrobial production) may be involved in the BBD disease process. Culture filtrates (CFs) from over 150 bacterial isolates from BBD and the surface mucopolysaccharide layer (SML) of healthy and diseased corals were screened for acyl homoserine lactone (AHL) and Autoinducer-2 (AI-2) QS signals using bacterial reporter strains. AHLs were detected in all BBD mat samples and nine CFs. More than half of the CFs (~55%) tested positive for AI-2. Approximately 27% of growth challenges conducted among 19 isolates showed significant growth inhibition. These findings demonstrate that QS is actively occurring within the BBD microbial mat and that culturable bacteria from BBD and the coral SML are able to produce QS signals and antimicrobial compounds. This is the first study to identify AHL production in association with active coral disease.

Effects of Multiple Ecological Drivers on Recruitment and Succession of Coral Reef Macroalgal Communities

The study evaluated the effects of herbivory pressure, nutrient availability and potential propagule supply on recruitment and succession of coral reef macroalgal communities. Recruitment and succession tiles were placed in a nutrient-herbivory factorial experiment and macroalgal abundances were evaluated through time. Proportional abundances of macroalgal form-functional groups on recruitment and succession tiles were similar to field established communities within treatments, evidencing possible effects of adult macroalgae as propagule supply. Macroalgal abundance of recruitment tiles increased with nutrient loading and herbivory reduction combined whereas on succession tiles nutrient loading increased abundance of articulated-calcareous only when herbivores were excluded. Macroalgal field established communities were only affected by herbivory reduction.

Herbivores strongly influence algal recruitment in both coral- and algal-dominated coral reef habitats

Coral reefs can exist as coral- and macroalgae-dominated habitats often separated by only a few hundred metres. While herbivorous fish are known to depress the abundance of algae and help maintain the function of coral-dominated habitats, less is known about their influence in algae-dominated habitats. Here, we quantified herbivorous fish and benthic algal communities over a 6 mo period in coral-dominated (back-reef) and algal-dominated (lagoon) habitats in a relatively undisturbed fringing coral reef (Ningaloo, Western Australia). Simulta - neously, we tested the effects of herbivorous fish on algal recruitment in both habitats using recruitment tiles and fish exclusion cages. The composition of established algal communities differed consistently between habitats, with the back-reef hosting a more diverse community than the Sargassum-dominated lagoon. However, total algal biomass and cover only differed between habitats in autumn, coinciding with maximum Sargassum biomass. The back-reef hosted high coral cover and a diverse herbivorous fish community, with herbivore biomass an order of magnitude greater than the lagoon. Despite these differences in herbivore composition, exclusion of large herbivores had a similar positive effect to foliose macroalgae recruitment on experimental tiles in both back-reef and lagoon habitats. Additionally, territorial damselfish found in the backreef increased turf algae cover and decreased crustose coralline algae cover on recruitment tiles. Collectively, our results show that disparate herbivorous fish communities in coral- and algaedominated habitats are similarly able to limit the recruitment of foliose macroalgae, but suggest that when herbivorous fish biomass and diversity are relatively low, macroalgal communities are able to escape herbivore control through increased growth.

Comparação da eficácia da ropivacaína 1% quando associada ou não à hialuronidase na anestesia peribulbar para cirurgia de catarata

Purpose: To evaluate the onset time and quality of peribulbar anesthesia with 1% ropivacaine associated or not with hyaluronidase 100 tru/ml for cataract extraction. Methods: Prospective, randomized, double-blind and controlled study including fifty-seven patients, scheduled to undergo peribulbar anesthesia for cataract extraction, allocated to two groups. Group C: 1% ropivacaine with addition of 100 tru/ml hyaluronidase, and Group S 1% ropivacaine, without hyaluronidase. The onset time for globe akinesia was studied at intervals of 2 minutes, using Nicoll's score. We evaluated pain by analogic score during the surgery and the necessity of complementing the anaesthesia. The peribulbar block was considered satisfactory when the Nicoll's score was less than 4. Results: The mean time of onset of block in group C was 4.07 minutes (± 3.24), and in group S 5.03 (± 3.28). There was no statistically significant difference between the groups. Both were similar regarding pain score, no pain was observed in 57.14% of group C, and in 68.97% of group S. The supplementary anesthetic was necessary in 2 cases of group C and in 3 cases of group S. Two cases of bradycardia (heart rate < 50 bpm) were observed during the surgery, and in one case administration of atropine IV was necessary. Conclusion: 1% ropivacaine provided a good quality of anesthesia for cataract extraction, with a faster onset of action in the group with hyaluronidase 100 iu/ml, although without significant difference.

Eficácia na utilização de córneas no transplante penetrante

PURPOSES: 1) To verify the impact of the creation of the Single Technical Record (STR) at the University of Campinas (Unicamp) Hospital das Clínicas, on the preservation period of corneas which were used in elective penetrating keratoplasties, and 2) to compare the primary failure incidence in cornea penetrating keratoplasties regarding the periods before and after the creation of STR. METHODS: A retrospective study was conducted at the Unicamp Hospital, which evaluated 15 consecutive cornea penetrating keratoplasties between January 1st and April 30th, 2000 and 24 consecutive penetrating keratoplasties between May 1st and September 20th of the same year (corneas under the control of the STR), totaling 39 keratoplasties. RESULTS: The mean time between cornea preparation and transplantation was 3.8 days (±1.78) in the period before STR creation, and 6.0 days (±2.97) after STR creation, representing a 36.7% increase in the preservation time. There was a statistically significant difference (p=0.02) between the two groups. No corneal primary failure was observed among the 39 transplanted patients in both groups. CONCLUSION: Based on the results of this study, it can be concluded that this new concept of the State Transplantation System has caused a statistically significant increase in the conservation period of corneas, which may reduce the period of a clear transplant due to an increased loss of endothelial cells, as well as increase the primary failure incidence or result in a high number of corneas that cannot be used due to having exceeded the preservation time recommended by the literature.
