Sleeping is one of the most important factors that influence the quality of human life, and this state of existence should be thoroughly investigated to improve the quality of the life. The mechanical design of bedding has great influence on the comfort of a mattress. Thus, objective and conventional techniques to evaluate the mechanics of mattress comfort could help improve the quality of sleep. In this report, an analysis technique for the assessment of the sleeping posture of humans is presented to facilitate the development of mattress design technology. Herein, an analytical model which imitates the human body has been formulated to determine the design parameters of a mass-spring-joint system on a soft underlay. The physical model is composed of five components that represent the head, chest, hip, femur, and calf, with each body part being represented by a simple ball model. The spring joint connecting the five parts reflects the neck, lumbar, hip, and knee joints. The specifications of the body model are determined by actual measurements and previous studies. In order to determine the physical properties of the mattress, two types of mattress urethane foam material are tested using the ball indenter method. The parameters include Young’s modulus, plateau stress, and other physical parameters. Variation due to the type of mattress has been observed in the laying test using a pressure distribution sensor sheet. In the analysis performed using the physical model, the variation in the lying posture and the extent of body sinking are observed to be the same during experiments. Both variations are compared using the change in force distribution in each body part. In conclusion, it was found that the observed changes in distribution are the same in the experimental and physical models. Therefore, the proposed model reliably reflects the design characteristics of the mattress.

The representation of the process of human life is at the heart of questions about longevity, rejuvenation practices and possibly those which aim at immortality. The key term for “age” in medieval India is vayas, which means “vigour”, “youth” or even  “any period of life”, that is to say  exactly the same meaning as ours (duration of life). As a criterion for the examination of the patient, vayas is invariably divided into three periods: childhood, intermediate age and old age, precisely defined in the ayurvedic saṃhitās. It seems that vayas might be a relevant gateway to the cross-disciplinary understandings of age in medieval India, and therefore to the conditions of its (relative) mastery.

Technical systems must be continuously improved so that they can remain competitive on the market. Also, the time-to-market is an important factor for the success of a product. To achieve this goal, new methods and processes are needed. Especially the testing and calibration are important phases in the development process. This paper introduces a method, which helps to reduce the time effort while increasing the quality of the calibration process. The basic idea is to use measured test data to parameterize a physical (or mostly physical) model structure to create adequate models for the optimization. The main advantage of the method is the reduction of test effort because the number of variations of the design parameter is one, or extremely decreased (depending on the system). Another advantage is that the uncertainty and the limit of the model can be quantified more accurately compared to common approaches based on non-physical model structures. These normally use artificial neuronal networks (ANN) or polynomial approaches for the test-based optimization. This contribution illustrates the method by using the example of the calibration process of a double clutch gearbox (DCT) regarding energy efficiency and drivability on a roller test bench. First step is the test planning and test execution. In this step the method calculates the optimal execution order of the measuring points. In this example 81% timesaving can be achieved compared to the equivalent on the test track. The second step is the automated generation of the simulation model. In this step the unknown parameters of the model structure are calculated. The contribution shows different approaches for the identification of non-linear systems. In the last step the model is used to perform the optimization of the design parameters.

Human Social Life

Activity of human social life is currently mediated by internet technology. Mediation has created space in the activities of social life which previously had an activity in the body replaced by activities in cyberspace. Instagram is a technological social space in the posfenomenological dimension of cyber space. Instagram as social media mediates its user body to be shared with other users. Instagram is a mode of reduced social interaction and transcends bodily space, programmed body, identity constructed in digital form. The metrosexual man enters the Instagram room to image himself and share it with other users. This research analyzes how metrosexual man activities in consumption and presents his identity in cyberspace. This study uses a virtual ethnographic method by tracing metrosexual male Instagram accounts through the hashtag #priadewasa #ganteng. This method can explore deeper about subject interactions on Instagram. The result is identity and consumption activities in the form of fashion, the places they visit are presented making it their class that has their own tastes in activities shared on Instagram. The liquid space provided by Instagram renders de-identification. Instagram space gives a different space unlike theworld off-line. Human life is never static, the dynamics of human life are changes that can never be avoided. These changes are a process of human adaptation to the movement of the surrounding environment. One form of human adaptation is to create technology that aims to simplify and improve the quality of life. Keywords: Instagram, Metrosexual, Identity, Consumption ABSTRAKAktivitas kehidupan sosial manusia saat ini termediasi teknologi internet.

Thermal deformation is a common phenomenon of thermal effect which has great influence to the accuracy of measurement. It is well-known that the dimension of components changes in corresponding to the variation of physical temperature. Traditional thermal deformation theory and calculating formulas are approximately applicable to the components of low or general precision requirement, but not to the requirement of high precision or modern nano-scale field. Traditional linearity formulas of thermal deformation only correlate to their own dimensions, which offers no enough accuracy. In real world situation, thermal deformation of any dimension is the function of interrelated dimensions. To correctly constitute mathematic model which reflects the effects of the body parameter to the thermal deformation has great significance in both research and application communities. In this paper, by constituting GM(1,1) of linear thermal expansion and putting in GM(1,2) of the effects of the parameters of the components, we can prove the effectiveness and the feasibility of gray model in treating the thermal deformation of body physical parameters.

Transtibial and transfemoral amputations are the most common amputations in the world, loss of lower extremity result in impaired function extremities and also body balance. A prosthesis is a medical device designed to replace a specific body part to restore function to a body part lost due to an accident or disease. Most doctors strongly recommend the use of a prosthesis so that patients can return to normal activities after undergoing an amputation. Besides functioning to support beauty, the use of prostheses is also to restore the quality of life of prosthetic users, the issue of metabolic energy consumption when walking is also very important in designing transtibial bionic prosthesis because it involves the comfort of the user transtibial prosthesis. Most of the existing transtibial prosthesis products in Indonesia are conventional passive transtibial foot products, and passive prosthesis users show a limp or asymmetrical gait pattern so that conventional passive prosthesis users experience discomfort when walking in the form of pain in the amputated leg and normal foot, which can cause secondary musculoskeletal injuries such as joint disorders. Passive prostheses cannot generate propulsive force during push-off phase (terminal stance and preswing) of the human gait cycle. The use of passive prostheses can also consume 20-30% more metabolic energy while walking so that it can cause fatigue for the user. Transtibial bionic prosthesis research is growing, transtibial bionic prosthesis can overcome the weakness of passive prosthesis because it can produce push-off during gait cycle and several researchers have shown that bionic prostheses are capable of mimicking the human gait, as well as improve the  performance in a more natural gait and normal walking. This study aims to study the existing transtibial bionic prosthesis by comparing between 6 existing designs of powered ankle or transtibial bionic prosthesis that have been published in several publications. The discussion focuses on the design and mechanical systems, actuators related to the selection of motors and drive mechanisms as well as power transmission from actuators to moving components.

As far as the human mind is developed, the area of ​​the miraculous and supernatural is wider and immense for it; therefore, all the incomprehensible and striking phenomena of him belong to him to the action of a higher, mysterious power. This is the origin of the world outlook of primitive peoples, in whom, over the course of time, invisible abstract forces were recognized as deities governing the fate of people, at which there usually arose the influence of deities on good and evil, clean and unclean. Deities have their servants angels and gods. Evil spirits and their incarnations in the image of bots, according to the primitive peoples and uncultured popular masses, have great influence on human life; unhappiness, death and illness depend on them. Sumtsov) says that diseases have long been among different peoples in the form of demonic beings. The spirits of darkness are doctors of health and life; they penetrate into the body of a person and serve as a source of illnesses, they darken the mind and torment the body. Already in the brick books of the ancient Chaldeans, there are conspiracies against diseases, like demonic beings. Among the Iranians, magic spells and cleansing from illnesses were widespread, like unclean demonic creatures. Among the Greeks and Romans, illnesses also had a demonic meaning, In the ancient Scandinavians, internal illnesses were attributed to the action of evil spirits and treated them with conspiracies and sympathetic means. In England in the X and XI centuries and later internal illnesses were considered directly caused by evil spirits, elves, demons, spells of sorcerers or the pernicious influence of the evil eye. The Slavs, in particular the Russians, share the demonic origin of illnesses with all other peoples.
