In this paper, we propose a new Intra-body communication system for bio-sensor which is one of applications in PAN(Personal Area Network) using body channel. The communication systems for bio-sensor network usually transmits a lot of data acquired in sensor to the receiver in wrist or waist. So we deign the intra-body modem with high data rate, low power, and small size which are achieved by baseband communication techniques. It is noted that the baseband transmission does not requires any analog IF and RF frontends, and can be operated in lower frequency than bandpass transmission. The proposed modem operates at 10MHz band according to the characteristics of intra-body channel, and shows the capability of 5Mbps data rate at distance of 20cm, with $BER=10^{-5}$. In addition, we implement the modem within $2{\times}2cm$ area.

This study was done to explore the relationship alcoholcs' body image, belief emotion expression, communication competence and related factors. Alcoholcs' body image, belief emotion expression, communication competence level scales were used as the measurement tools with a sample of 151 students from 2 hospitals in J-city and S-city. T-test, ANOVA, Pearson correlation and stepwise multiple regression with SPSS/WIN 21.0 version were used to analyze the data. Alcoholcs' body-image was negatively correlated with belief emotion expression but was negatively correlated with communication competence. Belief emotion expression was negatively correlated with communication competence. Hierarchical regression analysis showed that body-image, education degree, and belief emotion expression explained 24.9 % of communication competence. The results of this study can be used as basic data to improve the communication competence of alcoholics.

The major challenge in wireless body area networks (WBAN) is setting up a protected communication between data consumers and a body area network controller while meeting the security and privacy requirements. This paper proposes efficient and secure data communication in WBANs using a Twofish symmetric algorithm and ciphertext-policy attribute-based encryption with constant size ciphertext; in addition, the proposed scheme incorporates policy updating to update access policies. To the best of the author's knowledge, policy updating in WBAN has not been studied in earlier works. The proposed scheme is evaluated in terms of message size, energy consumption, and computation cost, and the results are compared with those of existing schemes. The result shows that the proposed method can achieve higher efficiency than conventional methods.

The basic equation of body and mind that can be represented as body and mind based on love model of Romeo and Juliet is presented in this paper. In order verify validity for physical idea of unification for body and mind when the external force is applied in the basic equation. We display the time series and phase portrait for nonlinear behavior, and this paper confirms the point of difference between body-mind neutral monism and body-mind dualism.

This paper aims to look into various symbolic meanings of the body shown in the film, Avatar (2009, James Cameron), and to ponder over a variety of media strategies carried by the pursuit of the corporality shown in this film. In a nutshell, the body in Avatar is a symbol of primitiveness rather than civilization, and the body language is a fundamental and effective means of communication much better than verbal language. A variety of physical contacts that appeared in many scenes of the movie emphasizes the role of the body as a means of real communication. Also, in the composition of the film dominated by the confrontation of civilization, numerous creatures in the planet Pandora with a variety of colors as well as a number of agencies and large body sizes express primitive richness. The narrative of the film telling the story of a 'moving' body ultimately emphasizes the superiority of the body with respect to consciousness, unlike the narrative of conventional movies dealing with the problems of the body. In addition, the corporality pursued by this film implies several important media strategies. It may reveal a self-reflection of the material civilization and the imperialism, or, on the contrary, an attempt to conceal or dilute them. It may also represent a self-reflection of the overdeveloped media technology, or simply the dilution of it. Finally, it may be an attempt to recover the feeling of "presence", not fully supported by the 3D technology, by the identification of the spectator's body and the character's body.

The purpose of this study was to investigate the influences of adolescents' body image and communication with their parents on the alienation of male and female middle school students. The subjects were 253 middle school students. The data were analyzed with SPSS win 18.0 using Cronbach's ${\alpha}$, t-test, one-way ANOVA, Scheff$\acute{e}$ test and stepwise regression. The findings showed that problematic communication with the father was the strongest factor in explaining the alienation of male middle school students. The second strongest factor was the middles school student's open communication with the mother, and the third strongest factor was the middle school student's perception of physical health. Unlike male students, open communication with the father was the strongest factor in explaining the alienation of female middle school students. Problematic communication with the mother was the second strongest factor. Perception of physical appearance was the third strongest, and perception of physical health was the fourth strongest factor. Based on the results of the study, implications were discussed in terms of the alienation of male and female middle school students.

This study aimed to systematically review the available body awareness interventions in patients with musculoskeletal disorders. A total of 3,462 studies were searched in relevant databases using the search keywords, and six studies that met the selection criteria after review were included in the final analysis. The qualitative level of the studies was classified using the five levels of evidence-based classification, and systematic analysis was conducted according to PICO model (patient/population, intervention, comparison and outcomes). Of the six studies included in the final analysis, there were one, three, and two randomized controlled trials, non-randomized two-group studies, and case reports, respectively. Body awareness therapy was applied to patients with idiopathic scoliosis, non-specific musculoskeletal disorder, hip osteoarthritis, and amputation, who showed positive improvements after the interventions. Our results suggested that body awareness therapy is an important intervention with positive effects on the recovery of patients with musculoskeletal disorders.

Body temperature plays an important role in medicine, some diseases are characterized by changes in human body temperature. Monitoring body temperature also allows doctors to monitor the effectiveness of medical treatments. Accurate body temperature measurement is key to detecting fevers, especially fevers related to infection with the SARS-CoV-2 virus that caused the recent Covid-19 pandemic in the world. The solution of measuring body temperature using a thermal camera is fast but has a high cost and is not suitable for some organizations with difficult economic conditions today. Use a medical thermometer to measure body temperature directly for a slow rate, making it easier to spread disease from person to person. In this paper, we propose a completely automatic body temperature measurement system that can adjust the height according to the person taking the measurement, has a measurement logging system and is monitored via the internet. Experimental results show that the proposed method has successfully created a fully automatic human body measurement system. Furthermore, this research also helps the school's scientists and students gain more knowledge and experience to apply Internet of Things technology in real life.

Intra-body communication' is a wireless communication technology that uses a body as a transmission medium for electrical signals. Generally, an 'earth ground' is used to create an electric field for operating the system; however this operating method could not apply to telemetry for implanted neural prosthetic devices. So this paper suggests a newly designed intra-body communication for neural prosthetic devices. A floating system which has a couple of electrodes with body was studied to remove an influence of the 'earth ground'. We found that 10MHz is the most suitable carrier frequency in skin experiments and over 3MHz in subcutaneous experiments. The system has been applied to a current stimulator circuit for cochlear implant that uses pulse width modulation (PWM) method at 480kbps rate successfully.
