Objetivou-se com este estudo caracterizar o perfil e avaliar o nível de satisfação que reflete na qualidade de vida no trabalho (QVT) de trabalhadores da colheita de madeira de duas contratadas (C1 e C2), por duas grandes empresas do setor florestal, sendo uma do segmento de papel e celulose (PC) e, a outra, do segmento de carvão vegetal (CV). A avaliação ocorreu a partir da percepção dos trabalhadores das contratadas em questão, utilizando um modelo pré-concebido que contempla 11 blocos ou dimensões referentes a variáveis intervenientes e definidores da QVT, englobando 48 trabalhadores em três categorias funcionais: operador de motosserra (7 trabalhadores da C1 PC e 10 da C2 CV), ajudante de motosserrista (7 trabalhadores da C1 PC e 8 da C2 CV) e operador de carregador florestal (11 trabalhadores da C1 PC e 5 da C2 CV). Os dados referentes às variáveis intervenientes na QVT foram obtidos a partir de escala fechada do tipo Likert, com os escores variando de 1 a 7, em que 1 correspondeu ao nível "bastante insatisfeito" e 7, ao nível "bastante satisfeito". O perfil dos trabalhadores é de pessoa jovem, baixo nível de escolaridade e pouco tempo de serviço na empresa. Quanto ao nível de satisfação no trabalho, constatou-se que os trabalhadores da C1 PC se encontravam "satisfeitos" e os da C2 CV, "mediamente satisfeitos" com o trabalho e as condições proporcionadas pelas respectivas empresas, apesar de estatisticamente não ter sido detectada diferença entre os valores médios encontrados nas duas situações, pelo teste de Mediana (P>0,01). Os fatores que mais contribuíram para esses resultados favoráveis foram os benefícios extras oferecidos pelas prestadoras de serviços, as condições de segurança no trabalho e o contentamento com o emprego formal.

The objective of this study was to characterize profile and satisfaction level, which reflects the quality of life (QOL) of forest workers of two contracts for harvest activities, one in the pulp and paper industry (PI) and another in charcoal industry (CI). The evaluation of the satisfaction indexes was carried out according to the workers perception by using a model including 11 parameters to reflect these workers QOL. The group study of 48 workers encompassed three functional categories: chainsaw operators (7 from C1 and 10 from C2), chainsaw operator's assistant (7 from C1 and 8 from C2), and log loader operators (11 from C1 and 5 from C2). Data regarding the factors involved in QOL were collected from a closed, Likert-type scale with scores ranging from 1-7, in which level 1 corresponded to "very dissatisfied" and level 7 to "very satisfied". The general profile of the group shows that most of them are young, with low level of education and employed in the companies for a short time. Overall, the employees of contractors of the paper and pulp industry are "satisfied" and those working for the charcoal company are only "moderately satisfied" with the work and policies offered by the respective companies, although no significant statistical difference was detected between the two groups, for the median test (P> 0.01). The main reasons behind these results are the general beneficts offered by the companies, the safety measurements and the overall satisfaction for been employed.

The work was carried out in natural stand of Pinus caribaea var. caribaea located in San Andrés, Forestry enterprise of La Palma in the Pinar del Río province. The objective was determine which method of wood extraction results more efficient and reduce damages to the soil vegetable. Three method were evaluated: 1- the extraction of tree length with oxen to landing; 2 - the extraction of tree length with tractor to landing; 3 - the extraction of tree length with oxen to short distance and using tractor up to landing places. The method the extraction of tree length with oxen to short distance and using tractor up to landing places, resulted the most efficient and the one which fewer damages on the vegetable cover of the soil.

El trabajo se realizó en rodales naturales de Pinus caribaea var. caribaea, ubicados en la unidad silvícola San Andrés, La Palma, provincia Pinar del Río. El objetivo de la investigación fue evaluar la eficiencia y los daños causados a la cubierta vegetal del suelo durante la operación de arrastre de madera. Se evaluaron tres métodos: 1 - el arrastre de fustes enteros con yuntas de bueyes hasta los patios de carga; 2 - el arrastre de fustes enteros con tractor hasta los patios de carga; 3 - el arrastre de fustes enteros con yuntas de bueyes hasta las pistas de arrastre y con tractor hasta los patios de carga. El método de arrastre de madera que consistió en la combinación del empleo de animales y de tractor resultó más eficiente y provocó menos alteraciones a la cubierta vegetal del suelo.

An study was carried out in the natural forests of Pinus caribaea, Pinar del Rio province, Cuba, aiming at the evaluation of the different methods used for clearcuting with chainsaw, using the cut-to-length system conducted in such a way to diminish the risks of the occupational diseases in chainsaw operators, and simultaneously to maintain the productivity levels and work quality. The rotation of the work was tested with an alternation controled method by refueling the chainsaw (MAC), and a free alternation method too (MAL). Both methods used: two chainsaw operators, the lever, and the directional felling in those trees exhibiting more than 40cm diameter. These methods were compared to each other, and to that one traditionally applied on natural forests (T), that consists of one operator and its assistant who besides maintaining their functions during this activity, do not use the lever nor make the directional felling, but rather adopt spontaneous pauses. According to the results, the MAC shows to be more appropriate because: it allows to reduce the risks of accidents and occupational diseases in chainsaw operators; provides the balance of the work physiologic load and the decreases of 13.69% in load and 52.08% in the noxious effects from chainsaw, although the productivity over the effective time showed an increase of 27.32% relative to method (T), so diminishing the operating costs that justify the basic wages corresponding to the operator's level for both integrants of the team.

El presente trabajo fue desarrollado en bosques naturales de Pinus caribaea, en la provincia de Pinar del Río-Cuba, para evaluar diferentes métodos en el corte raso con motosierra, empleando sistema de madera corta. Se experimentó la rotación del trabajo de un método de alternancia controlada de los operadores por el reabastecimiento de combustible de la motosierra (MAC) y un método con alternancia libre (MAL). En ambos métodos se utilizaron dos operadores en parejas, la palanca de empuje y la ejecución de la muesca direccional en árboles con diámetros superiores a 30 cm. Los métodos fueron comparados entre si y a su vez, con el que se aplica tradicionalmente en estas áreas (T), que consta de un operador y un ayudante que mantienen sus funciones durante la jornada, no usan la palanca de empuje, no efectúan la muesca direccional y toman descanso espontáneos. De acuerdo con los resultados el MAC es el más apropiado pues, redujo los riesgos de accidentes y enfermedades ocupacionales en los operadores de motosierras, al equilibrar y disminuir la carga fisiológica de trabajo en un 13,69%, redujo el tiempo de exposición a posturas incomodas, así como los efectos nocivos de la motosierra en un 52,08%, la productividad del tiempo efectivo se elevó en un 27,32% respecto al método (T), con la disminución de los costos de la operación, que justifican salarios básicos correspondiente al nivel del operador para ambos integrantes de las parejas.
