Mechanical Design of Robot Head with Human-like Emotions
Nguyen Khac Toan,Le Duc Thuan,Le Bao Long,Nguyen Truong Thinh 제어로봇시스템학회 2021 제어로봇시스템학회 국제학술대회 논문집 Vol.2021 No.10
One of the fields that has detonated lately dependent on the AI platform is humanoid robots. The facial expressions of robots, then again, are getting less and less attention. The design of a robot head that communicates a wide range of human-like expressions is described in this paper. The eye-eyelid, lip-jaw, and neck were the three main parts of the robot head under investigation. Mechanical structure of human head such as number of degrees of freedom, size, ability of joints, and major muscle groups to create movements in each part are determined based on anatomy. Then, facial expressions are analyzed dependent on AUs to find out reasonable control points. The mechanical structures of each part were designed to try to replicate the movement and expression as closely as expected. Additionally, proportions, sizes, distances of the designs, such as CoP-CoP, tr-n, n-sn, and so on, must closely resemble those of a human head. The robot head in this article is designed and modeled on an Asian human head. The result of the design, the head section is made up of three mechanisms connected by a shaft that runs through the entire head. Through the experimental process, the robot head can perform 6 of the basic expressions and movements like a real human head.

Breeding for Heat Tolerance Rice Based on Marker-Assisted Backcrosing in Vietnam
Nguyen Thi Lang,Pham Thi Thu Ha,Pham Cong Tru,Tran Bao Toan,Bui Chi Buu,조영찬 한국육종학회 2015 Plant Breeding and Biotechnology Vol.3 No.3
A total of six markers RM3586 and RM160 on chromosome 3 and RM3735, RM3471, RM3687 and RM3536 on chromosome 4 were used to select promising lines in backcrossing populations for heat tolerance at flowering stage in rice. Fifty lines selected in BC3F2, BC4F1, and BC4F2 and parents were planted in 2013, and 2014 dry seasons at the CLRRI field under natural heat stress and greenhouse to evaluate heat tolerance at the reproductive period. Heat tolerance scoring under field condition was based on percentage of unfilled grains. All selected lines exhibited their homozygous alleles with two heat tolerance germplasm N22 or Dular in QTL loci. Twelve lines harboring homozygous alleles to QTL loci RM3586 on chromosome 3 and RM3735 on chromosome 4, respectively were selected and evaluated to agronomic traits and yield potential. Four lines BC4-1-10-1 from OM5930/N22//4 *OM5930, BC4-5-8 from OM5930/Dular//4*OM5930, BC4-5-9-4 from AS996/N22//4*AS996, and BC4-6-3 from AS996/Dular//4 *AS996, respectively were finally selected to would be for regional adaptable test in Central Coast of Vietnam under heat stress condition to release to rice farmers.

Even though the combined use of ultrasound (US) and alpha-fetoprotein (AFP) is recommended for the surveillance of hepatocellular carcinoma (HCC), the utilization of AFP has its challenges, including accuracy dependent on its cut-off levels, degree of liver necroinflammation, and etiology of liver disease. Though various studies have demonstrated the utility of protein induced by vitamin K absence II (PIVKA-II) in surveillance, treatment monitoring, and predicting recurrence, it is still not recommended as a routine biomarker test. A panel of 17 experts from Asia-Pacific, gathered to discuss and reach a consensus on the clinical usefulness and value of PIVKA-II for the surveillance and treatment monitoring of HCC, based on six predetermined statements. The experts agreed that PIVKA-II was valuable in the detection of HCC in AFP-negative patients, and could potentially benefit detection of early HCC in combination with AFP. PIVKA-II is clinically useful for monitoring curative and intra-arterial locoregional treatments, outcomes, and recurrence, and could potentially predict microvascular invasion risk and facilitate patient selection for liver transplant. However, combining PIVKA-II with US and AFP for HCC surveillance, including small HCC, still requires more evidence, whilst its role in detecting AFP-negative HCC will potentially increase as more patients are treated for hepatitis-related HCC. PIVKA-II in combination with AFP and US has a clinical role in the Asia-Pacific region for surveillance. However, implementation of PIVKA-II in the region will have some challenges, such as requiring standardization of cut-off values, its cost-effectiveness and improving awareness among healthcare providers.
