Use of Deep Learning for Position Estimation and Control of Soft Glove
Jeesoo Ha,Dooyoung Kim,Sungho Jo 제어로봇시스템학회 2018 제어로봇시스템학회 국제학술대회 논문집 Vol.2018 No.10
Soft wearable robots comprised of deformable materials have recently attracted much attention in the field of applications for its lightness and elasticity. However, there exist some limitation to the control of wearable robots due to the complexity of the model and the conditions of the wearer. In this paper, we propose a learning-based position control method of soft wearable glove using a deep neural network (DNN). To analyze our proposed method, we fabricated a soft pneumatic glove and a control board for the glove based on open hardware platform data. With our developed system, we collected the pressure and position data of the soft glove using a Leap Motion sensor to train our soft glove position network (SGPN). Along with our proposed DNN model, we could enable open-loop control on the joint positions of the soft glove by supplying pressure to the actuator without prior knowledge of the wearer or the wearable robot such as hand size of the wearer or the stiffness of pneumatic actuator.

Secondary prevention via earlier detection would afford the greatest chance for a cure in premalignant lesions. We investigated the exomic profiles of non-malignant and malignant changes in head and neck squamous cell carcinoma (HNSCC) and the genomic blueprint of human papillomavirus (HPV)-driven carcinogenesis in oropharyngeal squamous cell carcinoma (OPSCC). Whole-exome (WES) and whole-genome (WGS) sequencing were performed on peripheral blood and adjacent non-tumor and tumor specimens obtained from eight Korean HNSCC patients from 2013 to 2015. Next-generation sequencing yielded an average coverage of 94.3× for WES and 35.3× for WGS. In comparative genomic analysis of non-tumor and tumor tissue pairs, we were unable to identify common cancer-associated early mutations and copy number alterations (CNA) except in one pair. Interestingly, in this case, we observed that non-tumor tonsillar crypts adjacent to HPV-positive OPSCC appeared normal under a microscope; however, this tissue also showed weak p16 expression. WGS revealed the infection and integration of high-risk type HPV16 in this tissue as well as in the matched tumor. Furthermore, WES identified shared and tumor-specific genomic alterations for this pair. Clonal analysis enabled us to infer the process by which this transitional crypt epithelium (TrCE) evolved into a tumor; this evolution was accompanied by the subsequent accumulation of genomic alterations, including an ERBB3 mutation and large-scale CNAs, such as 3q27-qter amplification and 9p deletion. We suggest that HPV16-driven OPSCC carcinogenesis is a stepwise evolutionary process that is consistent with a multistep carcinogenesis model. Our results highlight the carcinogenic changes driven by HPV16 infection and provide a basis for the secondary prevention of OPSCC. [BMB Reports 2018; 51(11): 584-589]

Roles of Vocabulary and Grammar Knowledge in L2 Reading Comprehension
Jeesoo Kim,Yunkyoung Cho 한국응용언어학회 2015 응용 언어학 Vol.31 No.1
The present study sought to investigate the roles of vocabulary and grammar knowledge in second language reading in the case of Korean adolescent learners of English. To this end, 200 high school learners were asked to take three tests: a vocabulary knowledge test, a grammar knowledge test, and a reading comprehension test. The Korean version of the Vocabulary Levels Test was employed to measure the learners’ vocabulary knowledge, while grammar knowledge was measured with a 50-item multiple-choice grammar test designed by the researchers. The reading comprehension test consisted of four passages, which were each followed by five comprehension questions. The results of statistical analyses suggested that while the intersection of vocabulary and grammar accounted for most of the expected reading variance, unique properties of each of the two variables also played individual roles in explaining L2 reading comprehension. Though vocabulary seemed to have a slightly larger effect, vocabulary and grammar had similar unique effects on L2 reading. Therefore, it can be concluded that both breadth of vocabulary and grammar knowledge have equal positive effects on the reading of English passages by Korean adolescent learners of English. Theoretical implications and directions for further studies are discussed.

Streptococcus mutans plays an important role in the development of dental caries in humans by synthesizing adhesive insoluble glucans from sucrose by mutansucrase activity. To explore the anti-cariogenic characteristics of rubusoside (Ru), a natural sweetener component in Rubus suavissimus S. Lee (Rosaceae), we investigated the inhibitory effect of Ru against the activity of mutansucrase and the growth of Streptococcus mutans. Ru (50 mM) showed 97% inhibitory activity against 0.1 U/mL mutansucrase of S. mutans with 500 mM sucrose. It showed competitive inhibition with a Ki value of 1.1 ± 0.2 mM and IC50 of 2.3 mM. Its inhibition activity was due to hydrophobic and hydrogen bonding interactions based on molecular docking analysis. Ru inhibited the growth of S. mutans as a bacteriostatic agent, with MIC and MBC values of 6 mM and 8 mM, respectively. In addition, Ru showed synergistic anti-bacterial activity when it was combined with curcumin. Therefore, Ru is a natural anti-cariogenic agent with antimutansucrase activity and antimicrobial activity against S. mutans.
