Although lymphoscintigraphy is a useful method of detecting malignancy in a sentinel node, conventional lympho-scintigraphy does not determine the exact anatomical location of that node. Breast cancer has the property of spreading to the whole body through the lymph nodes around the breast. If lymph node metastases are negative, a large lymphadenectomy is generally unnecessary. However, in lymphoscintigraphy with a radiopharmaceutical, the image may be less than ideal. We investigated three methods of image improvement for lympho-scintigraphy of breast cancer. Lymphoscintigraphy was performed 12 hours after injection of 37 MBq of 99mTc-phytate colloid into the peritumoral region. The particle size of 99mTc-phytate was 150-200 nm (labeling after 15 min). Images were obtained with dual-energy windows of 140±10 keV for the primary image and 90±20 keV for the scatter image. Image processing employed the Annular Background Subtraction (ABS) method and logarithmic analysis. In brief, first the dosage site was obliterated automatically, and then the background was removed. Next, the logarithm of each pixel value was taken to improve image contrast. Third, a binarization was employed for the pixels in the scatter image, and an outline was extracted. Three kinds of logarithmic processing were used in the three versions of image processing in attempting to improve the detection of the SLN. In addition, it was not necessary to cover the injection position with lead and metastasis of the injection position neighborhood was detected well.","PeriodicalId":253305,"journal":{"name":"Proceedings of the 2017 4th International Conference on Biomedical and Bioinformatics Engineering","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131266468","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}

A concept and application program for 3D simulation based on personal computer presented, enabling surgeons to relocate fracture fragments onto their original position. This laboratory default software, named PhysiGuide, employed to deal with a comminuted fracture fragments reduction. Four different registration techniques proposed: pairs point, mirrored-bone, anatomy landmarks and fracture line constraints. A proximal femoral fracture generated from CT scans used for evaluating the performance of the proposed registration. Displacements distant of fragments after reduction are calculated and compared to healthy bones as a ground truth. The translation and rotation errors in repositioning calculation and the contact between fracture fragments should be within a clinically acceptable range. The experimental results show the lowest displacement and good stability obtained by using the method of fracture line constraint. The root mean square error is ± 1.097 mm.","PeriodicalId":253305,"journal":{"name":"Proceedings of the 2017 4th International Conference on Biomedical and Bioinformatics Engineering","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121202404","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, literature studies on the organosolv pretreatment process for P. Purpureum were relatively rare. Therefore, in this research, organosolv pretreatment on P. Purpureum was studied and compared with different types of solvent (1-pentanol and ethylene glycol) and homogeneous catalysts (sodium hydroxide and sulfuric acid) in order to provide the feasibility study and filling the current research gap. The chemical composition of P. Purpureum was found to comprise of 21.50% lignin, 54.67% alpha cellulose and 23.83% of beta cellulose and hemicellulose. The substantial composition of cellulose and hemicellulose in P. Purpureum proved its promising potential as a raw material for bioethanol production. Ethylene glycol with concentration of 50.0 v/v% with addition of 2.0 v/v% of sodium hydroxide had proven to be the most effective organosolv pretreatment combination in removal of lignin (83.4%). In terms of lignocellulosic component recovery, this pretreatment solvent achieved up to 70.10% alpha cellulose recovery and 97.90% beta cellulose and hemicellulose recovery.","PeriodicalId":253305,"journal":{"name":"Proceedings of the 2017 4th International Conference on Biomedical and Bioinformatics Engineering","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124881483","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}

One of video games genre that nowadays is popular is Multi Player Online Battle Arena (MOBA). This MOBA games have high complexity and more challenging for player, so this genre is suitable for this research to see what in game events that makes player's stress. This research objective is to evaluate stress when playing video games using cognitive ergonomic approach to see what in-game characteristic that increase stress. Methods for this research are frequency analysis from average power, asymmetry, and alpha/beta ratio also theta/beta ratio. Frequency Analysis is conducted by using electroencephalogram data from respondent while playing DOTA 2.
