The questions were classified by indicators and variables selected to generate solutions to reduce social conflicts, which arise due to the emission of the particulate matter generated in the area before hauling tasks. Particulate matter is produced by hydraulic shovels, which load mineralized material and discharge it to a dump truck in mining operations. This survey was conducted among people who are specifically located in the Huari region. A study of the Social Conflict Monitoring Model (MMCS) tool was executed. It is used for recording, monitoring, and controlling this type of social conflicts, so that mining operations will not be affected in the short or long term. In addition, this model will help in discovering the opinions and/or comments when they are informed on a new method, which decreases generated particulate matter.

A terapia do espelho, técnica utilizada no tratamento de pacientes em reabilitação neurológica, tem mostrado bons resultados a um custo relativamente baixo. Nessa terapia, um espelho é colocado ao longo do plano sagital mediano do paciente entre os dois membros, superiores ou inferiores, com o intuito de transmitir estímulos visuais para o cérebro para induzir a ilusão dos membros em questão estarem se deslocando de forma síncrona. Considerando a simplicidade, os resultados obtidos e o baixo custo da terapia do espelho, neste trabalho exploramos recursos tipicamente disponíveis em dispositivos móveis do tipo tablet e smartphones para propor um modelo de acompanhamento remoto baseado na gravação e no compartilhamento de vídeos de sessões de terapia do espelho considerando dois tipos de usuários: terapeutas e pacientes. O modelo é apresentado na forma de um protótipo de um sistema de acompanhamento remoto de pacientes que utilizam a terapia do espelho em sua reabilitação. Especialistas avaliaram que o sistema apresenta grande potencial no auxilio à reabilitação de membros superiores, podendo ser utilizado por qualquer paciente em reabilitação pela terapia do espelho devido à sua facilidade de uso. Entre os trabalhos futuros viabilizados pela versão atual do sistema estão testes com pacientes em tratamento para verificação das implicações resultantes de sua utilização. / The mirror therapy technique used in the treatment of patients in neurological rehabilitation has shown good results in a relatively low cost. In this therapy, a mirror is placed along the median sagittal plane of the patient between the two limbs, higher or lower, in order to transmit visual stimuli to the brain to induce the illusion of the limbs are moving synchronously. Considering the simplicity, the results obtained and the low cost of mirror therapy in this work we explore resources available on mobile devices like tablet and smartphones to propose a remote monitoring model based on recording and sharing videos of mirror therapy sessions considering two types of users: therapists and patients. The model is presented as a prototype of a remote monitoring system of patients that use mirror therapy in their rehabilitation. Experts evaluated that the system presents great potential to aid in the rehabilitation of the upper limbs and may be used by any patient due to its ease of use. Among the future work made possible by the current version of the system are the patients tests verifying the implications of the system in the therapy.

The relationship between post-mortem state and changes of biological tissue impedance has been investigated to serve as a basis for developing an in-vitro measurement method for monitoring the freshness of meat. The main challenges thereby are the reproducible measurement of the impedance of biological tissues and the classification method of their type and state. In order to realize reproducible tissue bio-impedance measurements, a suitable sensor taking into account the anisotropy of the biological tissue has been developed. It consists of cylindrical penetrating multi electrodes realizing good contacts between electrodes and the tissue. Experimental measurements have been carried out with different tissues and for a long period of time in order to monitor the state degradation with time. Measured results have been evaluated by means of the modified Fricke-Cole-Cole model. Results are reproducible and correspond to the expected behavior due to aging. An appropriate method for feature extraction and classification has been proposed using model parameters as features as input for classification using neural networks and fuzzy logic. A Multilayer Perceptron neural network (MLP) has been proposed for muscle type computing and the age computing and respectively freshness state of the meat. The designed neural network is able to generalize and to correctly classify new testing data with a high performance index of recognition. It reaches successful results of test equal to 100% for 972 created inputs for each muscle. An investigation of the influence of noise on the classification algorithm shows, that the MLP neural network has the ability to correctly classify the noisy testing inputs especially when the parameter noise is less than 0.6%. The success of classification is 100% for the muscles Longissimus Dorsi (LD) of beef, Semi-Membraneous (SM) of beef and Longissimus Dorsi (LD) of veal and 92.3% for the muscle Rectus Abdominis (RA) of veal. Fuzzy logic provides a successful alternative for easy classification. Using the Gaussian membership functions for the muscle type detection and trapezoidal member function for the classifiers related to the freshness detection, fuzzy logic realized an easy method of classification and generalizes correctly the inputs to the corresponding classes with a high level of recognition equal to 100% for meat type detection and with high accuracy for freshness computing equal to 84.62% for the muscle LD beef, 92.31 % for the muscle RA beef, 100 % for the muscle SM veal and 61.54% for the muscle LD veal. / Auf der Basis von Impedanzspektroskopie wurde ein neuartiges in-vitro-Messverfahren zur Überwachung der Frische von biologischem Gewebe entwickelt. Die wichtigsten Herausforderungen stellen dabei die Reproduzierbarkeit der Impedanzmessung und die Klassifizierung der Gewebeart sowie dessen Zustands dar. Für die Reproduzierbarkeit von Impedanzmessungen an biologischen Geweben, wurde ein zylindrischer Multielektrodensensor realisiert, der die 2D-Anisotropie des Gewebes berücksichtigt und einen guten Kontakt zum Gewebe realisiert. Experimentelle Untersuchungen wurden an verschiedenen Geweben über einen längeren Zeitraum durchgeführt und mittels eines modifizierten Fricke-Cole-Cole-Modells analysiert. Die Ergebnisse sind reproduzierbar und entsprechen dem physikalisch-basierten erwarteten Verhalten. Als Merkmale für die Klassifikation wurden die Modellparameter genutzt.
