Assessment of the teaching-learning process in students of the health area: cardiopulmonary resuscitation maneuvers

OBJECTIVETo evaluate the skills and knowledge of undergraduate students in the health area on cardiopulmonary resuscitation maneuvers with the use of an automatic external defibrillator.METHODThe evaluation was performed in three different stages of the teaching-learning process. A theoretical and practical course was taught and the theoretical classes included demonstration. The evaluation was performed in three different stages of the teaching-learning process. Two instruments were applied to evaluate the skills (30-items checklist) and knowledge (40-questions written test). The sample comprised 84 students.RESULTSAfter the theoretical and practical course, an increase was observed in the number of correct answers in the 30-items checklist and 40-questions written test.CONCLUSIONAfter the theoretical class (including demonstration), only one of the 30-items checklist for skills achieved an index ≥ 90% of correct answers. On the other hand, an index of correct answers greater than 90% was achieved in 26 (86.7%) of the 30 items after a practical training simulation, evidencing the importance of this training in the defibrillation procedure.

Avaliação do Potencial de Jatropha Curcas L. para Produção de Biodiesel (Santiago - Cabo Verde)

Este estudo teve como principal objectivo contribuir para a avaliação do potencial da espécie Jatropha curcas L. (purgueira) para a produção de biodiesel na ilha de Santiago – Cabo Verde. Foi efectuada uma caracterização de várias populações de plantas espontâneas ou cultivadas em diferentes regiões ecológicas da ilha de Santiago, bem como de 13 ecótipos existentes no banco de germoplasma do INIDA. Essa caracterização incidiu sobre um conjunto de caracteres morfológicos, produção de frutos e sementes, teor em óleo nas sementes e sua composição em ácidos gordos. As produções de frutos e semente foram muito baixas, com excepção da amostra Chã de Vaca, apresentando as populações espontâneas da ilha produções superiores às do banco. O teor em óleo das sementes variou entre 15,6% e 35%, o que foi inferior ao obtido em anteriores estudos. Verificou-se existir uma correlação entre o peso da semente e o teor em óleo apenas para as populações sub espontâneas/cultivadas. A composição em ácidos gordos não apresentou grandes diferenças face a anteriores trabalhos salientando-se os apreciáveis teores de ácido linolénico e linoleico. As amostras da Loura, Chã de Vacas e 17 do banco de germoplasma têm um perfil em ácidos gordos com maior teor de ácido oleico.

Workloads and strain process in Community Health Agents

ABSTRACT OBJECTIVE To identify the workloads present in the work activities of community health agents (CHAs) and the resulting strain processes. METHOD A descriptive, exploratory, cross-sectional and quantitative study conducted with 137 CHAs. Data were collected through a questionnaire and interview guided by the health surveillance software called SIMOSTE (Health Monitoring System of Nursing Workers), following the ethical codes of the current law. RESULTS In total, were identified 140 workloads involved in 122 strain processes, represented by the occurrence of health problems of the CHAs. The mechanical (55.00%) and biological (16.43%) loads stood out. The most common strain processes were the external causes of morbidity and mortality (62.31%) and diseases of the musculoskeletal system and connective tissue (10.66%). CONCLUSION From the identified overloads, it became evident that all workloads are present in the work process of CHAs, highlighting the mechanical load, represented mainly by external causes of morbidity and mortality that are related to occupational accidents.

Validation of the New Mix Design Process for Cold In-Place Rehabilitation Using Foamed Asphalt, 2007

Asphalt pavement recycling has grown dramatically over the last few years as a viable technology to rehabilitate existing asphalt pavements. Iowa's current Cold In-place Recycling (CIR) practice utilizes a generic recipe specification to define the characteristics of the CIR mixture. As CIR continues to evolve, the desire to place CIR mixture with specific engineering properties requires the use of a mix design process. A new mix design procedure was developed for Cold In-place Recycling using foamed asphalt (CIR-foam) in consideration of its predicted field performance. The new laboratory mix design process was validated against various Reclaimed Asphalt Pavement (RAP) materials to determine its consistency over a wide range of RAP materials available throughout Iowa. The performance tests, which include dynamic modulus test, dynamic creep test and raveling test, were conducted to evaluate the consistency of a new CIR-foam mix design process to ensure reliable mixture performance over a wide range of traffic and climatic conditions. The “lab designed” CIR will allow the pavement designer to take the properties of the CIR into account when determining the overlay thickness.

Estudo do Uso de Hidrotalcites de Mg-Al como Catalisadores Heterogéneos para Produção de Biodiesel

A transesterificação de óleos vegetais ou gorduras animais com um álcool de baixo peso molecular é o principal processo utilizado na produção de biodiesel. Actualmente os processos industriais utilizam catalisadores homogéneos para acelerar a reacção. No entanto a utilização de catalisadores heterogéneos, no processo de transesterificação, tem sido sugerido por vários investigadores pois, são amigos do ambiente e podem ser regenerados e reutilizados portanto possibilitam a utilização de processos contínuos. Neste contexto, a utilização de hidrotalcites Mg-Al, como catalisadores heterogéneos para produção de biodiesel foi investigada neste trabalho experimental. As hidrotalcites com diferentes razões molares Mg/Al (Mg/Al=1, 2, 3 e 4) foram preparadas pelo método de co-precipitação. As diversas matrizes catalíticas obtidas, calcinadas a diferentes temperaturas, foram caracterizadas por difracção de raios X (DRX), análise térmica (TG-DSC), espectroscopia de infravermelhos (MIR), microscopia electrónica de varrimento (SEM) e isotérmicas de adsorção com azoto (BET). Estes catalisadores foram testados na metanólise de óleos vegetais para produzir biodiesel. As hidrotalcites Mg/Al=2, HT2A e HT2B (preparada com metade da quantidade de NaOH) calcinadas a 507 ºC e 700 ºC, respectivamente, foram as que apresentaram melhores resultados ao catalisar a reacção com um rendimento em éster superior a 97%, utilizando 2.5% da massa de catalisador, em relação à massa do óleo, razão molar metanol/óleo igual a 12, temperatura reaccional de 65 ºC durante 4h. Foi também investigada a reutilização do catalisador e o efeito da temperatura de calcinação. Constatou-se que o catalisador hidrotalcite HT2B apresentou melhor comportamento catalítico pois permitiu catalisar a reacção de transesterificação até três ciclos reaccionais, convertendo em ésteres 97%, 92% e 34% no primeiro, segundo e terceiro ciclos reaccionais, respectivamente. A análise de, algumas propriedades do biodiesel obtido como, o índice de acidez, a viscosidade e o índice de iodo mostraram que os resultados obtidos estão dentro dos valores limite recomendados pela norma EN 14214. Em anexo apresenta-se uma comunicação à First International Conference on Materials for Energy, Karlsruhe, 2010.

Spinning welfare: The gains from process innovation in cotton and car production

Economists and economic historians want to know how much better life is today than in the past.Fifty years ago economic historians found surprisingly small gains from 19th century US railroads,while more recently economists have found relatively large gains from electricity, computers and cellphones. In each case the implicit or explicit assumption is that researchers were measuring the valueof a new good to society. In this paper we use the same techniques to find the value to society ofmaking existing goods cheaper. Henry Ford did not invent the car, and the inventors of mechanisedcotton spinning in the industrial revolution invented no new product. But both made existing productsdramatically cheaper, bringing them into the reach of many more consumers. That in turn haspotentially large welfare effects. We find that the consumer surplus of Henry Ford s production linewas around 2% by 1923, 15 years after Ford began to implement the moving assembly line, while themechanisation of cotton spinning was worth around 6% by 1820, 34 years after its initial invention.Both are large: of the same order of magnitude as consumer expenditure on these items, and as largeor larger than the value of the internet to consumers. On the social savings measure traditionally usedby economic historians, these process innovations were worth 15% and 18% respectively, makingthem more important than railroads. Our results remind us that process innovations can be at least asimportant for welfare and productivity as the invention of new products.

Introducing systematic dispatcher-assisted cardiopulmonary resuscitation (telephone-CPR) in a non-Advanced Medical Priority Dispatch System (AMPDS): implementation process and costs.

OBJECTIVE: In order to improve the quality of our Emergency Medical Services (EMS), to raise bystander cardiopulmonary resuscitation rates and thereby meet what is becoming a universal standard in terms of quality of emergency services, we decided to implement systematic dispatcher-assisted or telephone-CPR (T-CPR) in our medical dispatch center, a non-Advanced Medical Priority Dispatch System. The aim of this article is to describe the implementation process, costs and results following the introduction of this new "quality" procedure. METHODS: This was a prospective study. Over an 8-week period, our EMS dispatchers were given new procedures to provide T-CPR. We then collected data on all non-traumatic cardiac arrests within our state (Vaud, Switzerland) for the following 12months. For each event, the dispatchers had to record in writing the reason they either ruled out cardiac arrest (CA) or did not propose T-CPR in the event they did suspect CA. All emergency call recordings were reviewed by the medical director of the EMS. The analysis of the recordings and the dispatchers' written explanations were then compared. RESULTS: During the 12-month study period, a total of 497 patients (both adults and children) were identified as having a non-traumatic cardiac arrest. Out of this total, 203 cases were excluded and 294 cases were eligible for T-CPR. Out of these eligible cases, dispatchers proposed T-CPR on 202 occasions (or 69% of eligible cases). They also erroneously proposed T-CPR on 17 occasions when a CA was wrongly identified (false positive). This represents 7.8% of all T-CPR. No costs were incurred to implement our study protocol and procedures. CONCLUSIONS: This study demonstrates it is possible, using a brief campaign of sensitization but without any specific training, to implement systematic dispatcher-assisted cardiopulmonary resuscitation in a non-Advanced Medical Priority Dispatch System such as our EMS that had no prior experience with systematic T-CPR. The results in terms of T-CPR delivery rate and false positive are similar to those found in previous studies. We found our results satisfying the given short time frame of this study. Our results demonstrate that it is possible to improve the quality of emergency services at moderate or even no additional costs and this should be of interest to all EMS that do not presently benefit from using T-CPR procedures. EMS that currently do not offer T-CPR should consider implementing this technique as soon as possible, and we expect our experience may provide answers to those planning to incorporate T-CPR in their daily practice.

FY 2007 Biodiesel Fuel Revolving Fund Expenditures Report

The Seventy-ninth General Assembly of the State of Iowa, 2001 Regular Session, passed Senate File 465 which was signed by the Governor on April 19, 2001. This act created the biodiesel fuel revolving fund (Fund) to be used to purchase biodiesel fuel for use in the Department of Transportation's (DOT) vehicles. The act directed that the Fund receive money from the sale of EPA credits banked by the DOT on the effective date of the act, moneys appropriated by the General Assembly, and any other moneys obtained or accepted by the DOT for deposit in the Fund. The act also directed the DOT to submit an annual report not later than January 31 of the expenditures made from the Fund during the preceding fiscal year. This is the sixth annual report under the act. In FY 2007, the DOT purchased from the Fund 14,958 gallons of neat soy oil for $31,615, or an average of $2.11 per gallon. This yielded 74,791 gallons of B 20, which is 20 percent biodiesel by volume. Since the beginning of FY 2008, the Fund has received deposits totaling $59,000 which are being used for continued biodiesel purchases.

The role of institutions in the contractual process

Human beings increase their productivity by specializingtheir resources and exchanging their products. Theorganization of exchange is costly, however, becausespecialized activities need coordination and incentiveshave to be aligned. This work first describes how theseexchanges are organized in an institutional environment.It then focuses on the dual effect of this environment-as with any other specialized resource, institutions maybe used for expropriation purposes. They enjoyspecialization advantages in safeguarding exchange butthey also make possible new forms of opportunism,causing new costs of exchange. Three perverse tendenciesare identified:In the legal field, there is a surplus ofmandatory rules and, at the same time, a deficit in default rules. Second, courts activity is biased againstthe quasi-judicial role of the parties and the market. Third, Market enforcement is based on reputationalassets that are badly exposed to opportunism.
