In developing countries, more people have to go through amputation as the number of limb losses due to accidents or diseases is increasing. In most cases, patients are unable to bear the cost of a functional prosthetic hand as the overall price surpasses their affordability. In this paper, we have proposed a cost-effective, affordable prosthetic hand that will use the Electromyography (EMG) signal from the residual part of the amputated limb of the patient. For controlling the prosthetic hand with residual EMG signals from the amputated limb, we have used an EMG extraction circuit which can be developed using simple electrical components. This result was later compared with the movement of the hand controlled by a commercially available EMG sensor. The prosthetic hand that we used in this research was designed in SOLIDWORKS and printed using a 3D printer. The developed hand can grab and grasp objects according to the will of its user.","PeriodicalId":380002,"journal":{"name":"2021 13th Biomedical Engineering International Conference (BMEiCON)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128998560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper will introduce a novel solution, called Shield, that aids in the prevention of most acts of sexual abuse or assault against children. The system is cost efficient, compatible with children’s day-to-day life and can keep parents connected and, aware of their child’s situation at all times. Shield is a smart system that detects child sexual abuse occurrence using a set of vital signs obtained by a smartwatch worn by the child. Additionally, it uses pressure sensors attached close to the child’s private areas in case they were violated. After the indication of a sexual abuse, the system produces an alarm to deter and stop the assaulter, it also takes a picture of the abuser using a hidden camera and sends it to the parents’ smart phone along with the location of the child.","PeriodicalId":380002,"journal":{"name":"2021 13th Biomedical Engineering International Conference (BMEiCON)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114641230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, failures including tunnel widening and loss of reduction are presented due to the use of this treatment technique. Previous studies reported that some fixation methods might potentially be a cause of failure in dislocation treatment. Therefore, this study aimed to investigate the fixation stability and effect of four different fixation methods in two-tunnel CC ligament reconstruction technique using finite element analysis. The simplified constructs of various surgical procedures were divided into four models, which were different in tunnel location and fixation method. 70 N loads in three different directions were applied on all models. Displacement and peak von Mises stress output parameters were evaluated. The magnitude of maximum stress occurred on clavicle in all models showed lower values than the average yield strength of that bone (114 MPa). Interestingly, the perpendicular tunnel position with O-loop fixation method generated stress value lower than other models. This type of fixation also exhibited the lowest displacement value in superior direction, which could be used to determine a good fixation stability. Therefore, the perpendicular tunnel position with O-loop fixation method may help to decrease risk of failure after treatment due to a criterion of cumulative stress on the construct.","PeriodicalId":380002,"journal":{"name":"2021 13th Biomedical Engineering International Conference (BMEiCON)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123908751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ASTM D412-06ae2 standard test showed that the natural rubber had higher tensile strength than PVC about 1.2 MPa. Rating of sixty-one evaluators showed the overall appearance of the natural rubber prosthetic fingers was good/ fair, especially for the dark tone color in all aspects evaluated (skin tone, outward appearance, detail of fingers, shape and contour).

An impedance analyzer chip AD5933, driven by an Arduino Nano, is utilized for measurements of the electrical impedance. The electrodes interfacing the tissue consist of two concentric standard hypodermic needles, separated by an insulating layer of PTFE. The electrical contact is established by two-pole splicing connectors. By a prior determination of the cell constant, the conductivity of the penetrated tissue type can be inferred from impedance values. The cell constant determined for the self-fabricated needle electrode is 3.72.10-3 m. For NaC1 solutions, percental differences between the conductivities found in this work and literature values are between 0.8 % and 37.7 %. For a test frequency of 100 kHz, only small differences from expected conductivity values (2.1 % for muscle, and 5.8 % for fat) are found in porcine tissue samples, demonstrating the ability to identify unknown tissue types. However, miniaturization of the needle as well as the consideration of the tissue’s permittivity is desired to increase detection quality.","PeriodicalId":380002,"journal":{"name":"2021 13th Biomedical Engineering International Conference (BMEiCON)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115068276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the effects of working memory training, three assessment tasks were used: mental arithmetic, writing English sentences, and backward digit reciting. The results showed that there was no significant difference in the effectiveness of training between the training and control groups. However, there was a little tendency of the effects of the training when it came to memorizing multiplication and reciting many numbers in reverse, which consume a large amount of working memory capacity.These results seemed to be thought to be due to the short training program period and short time of training in each session.","PeriodicalId":380002,"journal":{"name":"2021 13th Biomedical Engineering International Conference (BMEiCON)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115500796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
