This article proposes an example of a multiplatform interactive serious game, which is an additional tool and assistant used in the rehabilitation of patients with musculoskeletal system problems. In medicine, any actions and procedures aimed at helping the rehabilitation of patients should entail the most comfortable, but at the same time, effective approach. Regardless of how these actions are orientated, whether for rehabilitation following surgery, fractures, any problems with the musculoskeletal system, or just support for the elderly, rehabilitation methods undoubtedly have good goals, although often the process itself can cause all kinds of discomfort and aversion among patients. This paper presents an interactive platform which enables a slightly different approach to be applied in terms of routine rehabilitation activities and this will help make the process more exciting. The main feature of the system is that it works in several ways: for normal everyday use at home, or for more in-depth observation of various biological parameters, such as heart rate, temperature, and so on. The basic component of the system is the real-time tracking system of the body position, which constitutes both a way to control the game (controller) and a means to analyze the player’s activity. As for the closer control of rehabilitation, the platform also provides the opportunity for medical personnel to monitor the player in real time, with all the data obtained from the game being used for subsequent analysis and comparison. Following several laboratory tests and feedback analysis, the progress indicators are quite encouraging in terms of greater patient interest in this kind of interaction, and effectiveness of the developed platform is also on average about 30–50% compared to conventional exercises, which makes it more attractive in terms of patient support.

The accidental fall is the major risk for elderly especially under unsupervised states. It is necessary to real-time monitor fall postures for elderly. This paper proposes the fall posture identifying scheme with wearable sensors including MPU6050 and flexible graphene/rubber. MPU6050 is located at the waist to monitor the attitude of the body with triaxial accelerometer and gyroscope. The graphene/rubber sensors are located at the knees to monitor the moving actions of the legs. A real-time fall postures identifying algorithm is proposed by the integration of triaxial accelerometer, tilt angles, and the bending angles from the graphene/rubber sensors. A volunteer is engaged to emulate elderly physical behaviors in performing four activities of daily living and six fall postures. Four basic fall down postures can be identified with MPU6050. Integrated with graphene/rubber sensors, two more fall postures are correctly identified by the proposed scheme. Test results show that the accuracy for activities of daily living detection is 93.5% and that for fall posture identifying is 90%. After the fall postures are identified, the proposed system transmits the fall posture to the smart phone carried by the elderly via Bluetooth. Finally, the posture and location are transmitted to the specified mobile phone by short message.

In the last 4 years, we have developed a partnership between dance and neuroscience to study the relationships between body space in dance and the surrounding space, and the link between movement and audition as experienced by the dancer. The opportunity to work with a dancer/choreographer, an expert in movement, gives neuroscientists better access to the significance of the auditory-motor loop and its role in perception of the surrounding space. Given that a dancer has a very strong sense of body ownership (probably through a very accurate dynamic body schema) ( Walsh et al. 2011 ), she is an ideal subject to investigate the feeling of controlling one's own body movements, and, through them, events in the external environment ( Moore et al. 2009 , Jola et al in press). We conducted several work sessions, which brought together a choreographer/dancer, a neuroscientist, a composer, and two researchers in acoustics and audio signal processing. These sessions were held at IRCAM (Institute for Research and Coordination Acoustic/Music, Paris) in a variable-acoustics concert hall equipped with a Wave Field Synthesis (WFS) sound reproduction system and infrared cameras for motion capture. During these work sessions, we concentrated on two specific questions: 1) is it possible to extend the body space of the dancer through auditory feedback ( Maravita and Iriki 2004 )? and 2) can we alter the dancer's perception of space by altering perceptions associated with movements? We used an interactive setup in which a collection of pre-composed sound events (individual sounds or musical sentences) could be transformed and rendered in real time according to the movements and the position of the dancer, that were sensed by markers on her body and detected by a motion tracking system. The transformations applied to the different sound components through the dancer's movement and position concerned not only musical parameters such as intensity, timbre, etc. but also the spatial parameters of the sounds. The technology we used allowed us to control their trajectory in space, apparent distance and the sound reverberation ambiance. We elaborated a catalogue of interaction modes with auditory settings that changed according to the dancer's movements. An interaction mode is defined by different mappings of position, posture or gesture of the dancer to musical and spatial parameters. For instance, a sound event may be triggered if the dancer is within a certain region or if she performs a predefined gesture. More elaborated modes involved the modulation of musical parameters by continuous movements of the dancer. The pertinence at a perceptive and cognitive level of the catalogue of interactions has been tested throughout the sessions. We observed that the detachable markers could be used to create a perception of extended body space, and that the performer perceived the stage space differently according to the auditory feedback of her action. The dancer reported that each experience with the technology shed light on her need for greater awareness and exploration of her relationships with space. Real-time interactivity with sound heightened her physical awareness – as though the stage itself took on a role and became another character.

The Stability

Nowadays, the objects of forensic handwriting analysis are often become short handwritten records of elderly people and senile. The study of such records is one of the most difficult when conducting handwriting examination. This is due to the nature of this object, which is often subjected to changes due to insufficient written practice, influence of age-related changes in the body or conditions common for the elderly people and senile, frequent execution of short handwritten records in unusual conditions, and sometimes with the help of other people, limitations in the studied graphic material. The article attempts to substantiate and systematize theoretical knowledge on the study of short handwritten records executed by elderly and senile people through analyzing the literature and forensic practice on the study of this type of objects, establishing individual patterns of handwriting, explaining the nature of diagnostic signs occurrence, determining the structure of the process for solving the mentioned tasks. Cases from practice and related problematic aspects of solving identification and diagnostic tasks are considered. The main characteristics of impaired ability (sensory, amnestic and motor aphasia) to write are given. Literature sources are analyzed, which consider the physiological mechanisms of the formation of writing skills and the features of their changes due to various conditions in elderly and senile people. Handwriting can undergo changes owing to aging of the body. Disorder of hand-eye coordination, conditions of the musculoskeletal system, nervous system, circulatory disorders, inherent for elderly and senile people, affect the stability of handwriting features. Testaments, contracts of sale and donation, bank documents are often signed by people of elderly and senile age shortly before death resulting from a serious long illness after experiencing such conditions as stroke or myocardial infarction. It is the aging of the body that is accompanied by deterioration in the state of health, impaired vision, muscle weakness, depletion of the nervous system, decreased mobility of the musculoskeletal system and impaired blood circulation. Features of writing motor skill functioning in the elderly and senile people lead to a slowdown in the tempo of movement, decrease in their amplitude and speed, decrease in the plasticity of movements. The correct ratio of such signs as proficiency and coordination of movements is of great importance. In addition, short handwritten records executed by the elderly and senile people contain a limited amount of graphic material. At the moment of executing a short recording, even under normal conditions, the performer needs a certain adaptation to a situation, which can not be performed while rare or occasional execution of a single short record. Therefore, the stability of a skill while executing short recording has an increased spread, and selective variability has low thresholds.

The number of elderly people worldwide is rigidly increasing due to decrease in birth rates and innovations implemented in medical field. Due to the increase in elderly people population diseases like dementia are also being increased year by year. Having done many kinds of research it is found that there is no permanent treatment for diseases like dementia, even if those patients come in public they look similar to normal people, however, people with dementia have abnormal behaviors like loss of patience, aggression, lack of thinking which in turn causes burden to family members and caretakers. In order to address this issues, this paper demonstrates a follow-up and rescue program for the elderly. The system includes a GPS receiver, a GSM module and a long-distance RF transmitter and receiver, real-time location. Families and care takers can obtain real-time information and history of patient location through GPS to avoid loss of elderly patients. With the help of this system, the number of losing patients will be decreased and the pressure on the caretakers and family people will be cut down to some extent.

Title: Development of Inclusive Hanger Design to Facilitate Clothes Drying Activities Laundry activities, including drying are still recommended to be done by the elderly independently. However, the decline in the physical condition of the elderly, including a decrease in the balance of body position, cannot be avoided. In the observation at the GKJ Gondokusuman nursing home, the drying place is uses a rope on the roof or pole that is quite high from the reach of the elderly hand. When drying clothes, the elderly must stretch their arms and tiptoe because of the differences in height of the clothesline. This condition can increase the risk of accidents for the elderly who lose balance. This study aims to develop a product to dry the laundry and reduce the distance between the users with a high clothesline. This product development was using design research and product design. The research method was based in ergonomics knowledge through an inclusive design approach. The techniques used were behavioral observation, assessment of body activities, like Nordic Body Map (NBM) and Rapid Entire Body Assignment (REBA). The results of the NBM stated that the elderly experienced pain in the right side of the body, while the results of the REBA assessment showed a score of 10. This condition showed that the elderly posture while drying still had a high risk of injury. As the results of these studies, the product is designed with a function to hang laundry that make user's body position more balanced because there is no need to stretch arms and tiptoe too high. Users also easily put clothes on the hanger because there is a grip feature for both hands.

Reduction Of Energy Consumption

In this study, the focus is on reducing the energy that is consumed by a compressor for providing high air pressure in the reservoir. A new air suspension configuration is presented that is titled active interconnected air suspension with outsourced air pressure. In this configuration, a compressor is used to charge the tank; meanwhile, the air springs are connected. For minor excitation, first, the air flows between air springs to control roll angle and height adjustment. If the situation of body position gets worse, the compressed air tank compensates to keep the body not generating roll angle and bounce. This methodology has a benefit. This configuration conserves compressed air in the tank in minor road elevation. The optimized controllers are designed to control roll angle and bounce, but they determine the outsourced air mass flow rate. For switching between interconnection and outsourced mode, there are some rules defined based on game theory for a trade-off between high dynamical performance quality of the vehicle and reduction of energy consumption. The optimization is done on the rules to keep both aspects minimum as much as possible. A three-axle heavy truck is used, and its performance is under discussion on an uneven rough road. Roll angle is improved progressively in novel air suspension configuration, and the energy consumption is reduced. In the default condition, the roll angle is improved 72% from the passive case and 39% from the conventional configuration. Furthermore, the energy consumption optimized version reduces 14% from the non-optimized case and 46% from the outsourced mode. By importing road power spectral density type E and type G, as the short domain and high-frequency vibrations, to two sides of the truck, it is inferred that the vehicle could remain on interconnection mode entirely without using the compressor.

The purpose on the thesis is the analyses to determine the impact of the type of physical activity associated with the selected production process on the size and structure of the static load of the human musculoskeletal system by work. On the basis of a time-lapse analysis postural changes of employee was analyzed. The load on the musculoskeletal system of the employee was determined using the OWAS method. In all the cases of physical work analyzed, the positions of the individual elements of the body were imposed due to the character of the activities performed. The attitude of the employee's body position during the work can qualify for the first and second load categories. There is no need to make sudden changes at the workstation but it may be necessary in the future.
