Cadernos de Saúde Pública , 1990, DOI: 10.1590/S0102-311X1990000300011
Abstract: this debate was organized at the epidemiology department of the national school of public health (brazil) and took place on june 28, 1989. the main reasons and factors which led the world health assembly resolution to eradicate poliomyelitis from the globe were discussed. first, it was discussed the tremendous decline in roparalytic cases due to wild poliovirus infections as a result of the immunization coverage acceleration in the americas through the national immunization days strategy as complementary to routine immunizations. second, epidemiological surveillance improvements in the opv and in the social mobilization methods were considered to be key factors for the eradication to be achieved. third, it was also discussed the impacts of immunizations on the nutritional status of children in some brazilian areas. the discussion also considered the situation of the epi and the perspectives for polio eradication in various regions of the globe. the main issues raised at the debate were discussed under the lights of the experience learned from the global smallpox eradication program. finally, a discussion was held on the importance of disease eradication and its impacts on people's health conditions.
Mechanization in firewood harvesting in southern Italy
Verani S,Sperandio G
Forest@ , 2005,
Abstract: The aim of this research was to survey current mechanization level of coppice harvesting in Southern Italy. The cooperation of the General Direction of the National Forest Service (NFS) has been a basic tool of survey. A questionnaire compiled on purpose was sent to each Forest Station (hereinafter referred to as CS) in the following regions: Basilicata, Campania and Calabria. A high percentage (80%) of the CSs did fulfill the questionnaire. The answers highlight that: i) the main assortment currently produced is firewood; ii) the level of harvesting mechanization is rather low, equipment being quite obsolete: indeed, the most widely used machineries are farm tractors partly adapted to forest harvesting and equipped with cages or back winch; iii) the use of animals for hauling (mules and oxen, the latter in Calabria) is still quite frequent, while forest tractors, polyethylene chutes and cable cranes are almost absent; iv) the use of individual protection (DPI) and machinery protection devices (DPM) is on average quite low.

Forest@ , 2012, DOI: 10.3832/efor0707-009
Abstract: Poplar stump grinding: analysis of work time and costs. After harvesting and extracting poplar trees, the agricultural land should be restored for further cultivation by removing the root systems. This operation is done with extraction or stumps grinding using special machines. In Italy, the stumps grinding is actually the operation more practiced. This paper deals with an analysis of work time, productivity and costs of the poplar stumps grinding, performed by two different operators. The poplar plantation was established with Neva (Populus x euramericana) clone and was harvested in march 2012. The plantation was located in Monterotondo (Rome), inside the farm of the Agricultural Engineering Research Unit (CRA-ING). Inside of two experimental plots, of the unit surface area of 0.66 ha, the diameters of all the stumps (220) has been measured in order to establish a correlation between the gross grinding time and the diameter of the grinded stump. The influence of diameter of stump on the grinding cycle time was assessed by a regression of the type T = A + Bx, where T is the gross time of grinding, A and B coefficients to be determined and x is the diameter of the stump. The resulted regressions were subjected to ANOVA test. The results showed an average work productivity of 111 stumps h-1, with significant differences between operators that underlines the importance of experience and competence of the operator. The productivity obtained on stumps with small diameters (23 cm) can reach 157 stumps h-1 for the expert operator, against 106 stumps h-1 of a less expert operator. The economic analysis was assessed on a cost per stump and per hectare. In referring to the average of the stumps diameters in the experimental plots (30 cm), an average cost of 1.57 € stump-1 was calculated, corresponding to 522 € ha-1, with a lower cost for expert operator corresponding to 424 € ha-1 (1.27 € stump-1), and a higher cost for the other operator of € 620 ha-1 (1.86 € stump-1).
Fatores culturais associados à doen?a da reclus?o do alto Xingu (Brasil Central)

Cadernos de Saúde Pública , 1991, DOI: 10.1590/S0102-311X1991000400005
Abstract: this article presents an anthropological approach to the symbolic aspects of the disease, considering traditional representations about the puberty seclusion syndrome which affects adolescent indians from the upper xingu region (central brazil), in a comparative perspective with the clinical-epidemiological approach. the traditional nosological category and its etiological implications in indigenous medicine and culture are contrasted with the western medical category - a peripheral neuropathy, possibly of toxic origin - identified in some cases of the syndrome. an epidemiological analysis of the data collected from the traditional point of view shows relations with events of cultural origin, associated with social and political contexts and with the nature of cross-cultural relations. moreover, this culture-bound syndrome presents some methological issues for western medicine, particularly for biomedical and social-epidemiological approaches. finally, the authors make explicit some cultural assumptions characteristic of modern western society, underlying the procedures used by the scientific disciplines involved.
Evaluation and management of blue crab Callinectes sapidus (Rathbun, 1896) (Decapoda - Portunidae) fishery in the Estuary of Cananéia, Iguape and Ilha Comprida, S?o Paulo, Brazil

Abstract: the estuary of cananéia, iguape and ilha comprida is a part of the estuarine lagoon system of cananéia, iguape and paranaguá , on the south coast of s?o paulo state, brazil. it has been recognised for its high standards of environmental conservation. the objective of this paper was to assess the blue crab (callinectes sapidus) fishing in the region, from january 1998 to december 2006, and obtain supportive data to implement technical rules for the rational exploitation and resulting conservation of this resource. the results show a remarkable decrease in the fisheries' abundance index (cpue) up to 2005, from 9.4 to 4.0 kg/hour, mainly caused by an increase in fishing effort, from 1,960 to 13,776 hours on a yearly basis. with the decrease in the fishing effort in 2005 and 2006, the abundance index reacted positively, indicating a recovery of the exploited population. due to the lack of appropriate regulation limiting the fishing effort and organising the fluctuating admission rates of new fishermen, there is a noticeable increase of the effort, above the sustainable level. therefore, there is a need for measures to limit and control the admission of fishermen in this activity. one of the measures to be considered is the establishment of regular periods where fishing the species is prohibited (called "defeso"), each year, especially from september to january. another measure is to create a fishermen registry and special licenses, to limit the number of new entrants. such actions require, for their implementation, a co-managed initiative, involving the blue crab fishermen themselves, governmental agencies and resource management researchers, and the integration of ecological, socioeconomic and cultural dimensions.

Forest@ , 2010, DOI: 10.3832/efor0605-007
Abstract: Working times observed during different harvesting phases in a poplar short rotation coppice (second rotation) were calculated. The main objective of the work was to evaluate the yard productivity and the economic gain in order to furnish good indications to the field operators about the harvesting planning. A comparisons between productivity and economic features was carried out on observed (experimental yard) and optimized data (optimized yard), the latter characterized by the absence of the inproductive times due to suboptimal yard organization. The harvested gross time as a function of distance covered by machine was assessed using linear regressions methods. The observed average biomass in plantation was 47.32 t ha-1. The harvesting gross average productivity observed in experimental yard was 34.20 t h-1 and the optimized was 54.16 t h-1. The working ability was 0.76 and 1.18 ha h-1 for experimental and optimized yard, respectively. The final product (chips) costs estimated was 9.81 euro t-1 and 444.46 euro ha-1 in the experimental yard. The optimized yard was 22-24% more efficient. This paper demonstrates the feasibilty to estimate harvesting times and costs per hectare using linear regressions with good approximation when the standing biomass in plantation is known.
