Ting Ru Lin,Yan-Yu Lin,Ting An Lin,Jia-Ci Jhang,Ching-Wen Lou,Jia-Horng Lin 한국섬유공학회 2020 Fibers and polymers Vol.21 No.9

In countries with severe gun regulations, soldiers and police officers are commonly attacked by sharp weapons. The current personal protective equipment is too heavy, and therefore, in this study, mechanically strong Kevlar® fibers,nylon fibers, and Low-melting-point polyester (LMPET) fibers are needle punched to make thin, light, and comfortablenonwoven fabrics. Hot-baking and hot-pressing heat treatments are used for thermal bonding fibers, which subsequentlygenerate a dense and rigid surface because nonwoven fabrics are subjected to damaged structure by needle punch or aslippery state due to the fibers’ properties. The results of the air permeability, tensile strength, and quasi-static stab resistancetestings verify that the dense surface is correlated with hot-pressing heat treatment.

Effect of HPFRCC on Seismic Performance of Beam-Column-Slab Subassembly

Ting-Ting Lu,Xing-Wen Liang 대한토목학회 2020 KSCE JOURNAL OF CIVIL ENGINEERING Vol.24 No.12

High performance fiber reinforced cementitious composites (HPFRCC) material exhibits strain-hardening and multiple cracking behaviors. Using HPFRCC in the reinforced concrete (RC) frame is considered to improve the seismic performance and damage mechanism of structure. Three beam-column-slab subassemblies were tested under cyclic loading, and eight frame models were simulation by ABAQUS. In this paper, the effect of substitution of concretewith HPFRCC on the seismic performance and damage mechanism of subassemblies was investigated. According to the test results, the lateral bearing capacity and deformability of beam-column-slab subassemblies increased by above 10% through using the HPFRCC material in the expected damage positions. The shear resistance of the joint zone with HPFRCC material increased by 1.6%, the shear deformation of the joint zone decreased by 7.9%. And the contribution of slab bars to the beam flexural bearing strength also decreased for that the yielding range and the strain amplitude of slab bars are limited through using HPFRCC material. Consequently, the subassemblies were prone to the “strong column - weak beam” damage mechanism to using HPFRCC material in the expected damage positions.

Wen-Ting Li,Yu Wang,Fen-Fang Deng,Li-Li Liu,Hai-Jun Nan,He Li 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2015 NANO Vol.10 No.8

A novel electrochemical immunosensor for determination of carcinoembryonic antigen (CEA) in human serum was fabricated by depositing Mo–Mn3O4/MWCNTs/Chits nanocomposite onto an indium-tin oxide (ITO) electrode. Mo-doped Mn3O4 (MMO) was synthesized by sol–gel method and the presence of molybdenum improved its electrochemical properties. The MMO/ MWCNTs/Chits nanocomposite could accelerate the electron transfer rate and enlarge the surface area to capture a large number of Carcinoembryonic Antigen (CEA). The factors influencing the performance of the immunosensor were investigated, such as incubation time, incubation temperature and pH. Under optimal conditions, the electrochemical immunosensor could detect CEA in a linear range from 0.1 ng · mL-1 to 125 ng · mL-1 with a detection limit of 4.9 pg · mL-1 (S/N = 3). In addition, it exhibited high sensitivity and acceptable stability on a promising immobilization platform for signal amplification, which could be extended to other labeled recognition systems. This electrochemical immunosensor may provide potential applications for the clinical diagnosis.

Efficient Keyword-Aware Representative Travel Route Recommendation

Wen, Yu-Ting,Yeo, Jinyoung,Peng, Wen-Chih,Hwang, Seung-Won IEEE 2017 IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERIN Vol.29 No.8

<P>With the popularity of social media (e.g., Facebook and Flicker), users can easily share their check-in records and photos during their trips. In view of the huge number of user historical mobility records in social media, we aim to discover travel experiences to facilitate trip planning. When planning a trip, users always have specific preferences regarding their trips. Instead of restricting users to limited query options such as locations, activities, or time periods, we consider arbitrary text descriptions as keywords about personalized requirements. Moreover, a diverse and representative set of recommended travel routes is needed. Prior works have elaborated on mining and ranking existing routes from check-in data. To meet the need for automatic trip organization, we claim that more features of Places of Interest (POIs) should be extracted. Therefore, in this paper, we propose an efficient Keyword-aware Representative Travel Route framework that uses knowledge extraction from users' historical mobility records and social interactions. Explicitly, we have designed a keyword extraction module to classify the POI-related tags, for effective matching with query keywords. We have further designed a route reconstruction algorithm to construct route candidates that fulfill the requirements. To provide befitting query results, we explore Representative Skyline concepts, that is, the Skyline routes which best describe the trade-offs among different POI features. To evaluate the effectiveness and efficiency of the proposed algorithms, we have conducted extensive experiments on real location-based social network datasets, and the experiment results show that our methods do indeed demonstrate good performance compared to state-of-the-art works.</P>

Preparation and Mechanical Property Evaluations of Puncture-Resistant Insoles Composites Reinforced by High-Modulus Filament and Thermal Bonding

Ting-Ting Li,Fei Sun,Xing Liu,Hua-Ling Wu,Ching-Wen Lou,Jia-Horng Lin 한국섬유공학회 2018 Fibers and polymers Vol.19 No.6

High-modulus PET filaments and thermal bonding are used to reinforce the puncture resistance stability of the insole composite. This study aims to discuss the influences of the amount of low-melting-point polyester fibers (LMPET) and needle densities (ND) on tensile, bursting, and quasi-static puncture resistance properties. Besides, significance of LMPET amount and ND on puncture resistance against flat-head (A), spherical-head (B), and pointed-head (C) probes are in particular investigated to simulate the diversified application environments for insoles. Research result shows that, LMPET amount significantly affects the static puncture resistance against three probes; ND only significantly influences the puncture resistance against Probe A and C. Thermal bonding significantly improves the puncture strength against Probe B with various LMPET amounts of insoles, but evidently increases the puncture resistance against Probe A and C when being punched at various ND. The amount of LMPET fibers has a positive influence on the puncture strength of insoles, and 70 wt% of LMPET provide the average static puncture resistance up to 342.6 N. The high-modulus resultant insoles have advantages of flexibility, ease of process, and bendability with a higher and more stabilized puncture resistances.

Chronic inflammation is thought to be the leading cause of colorectal cancer, and interleukin-10 (IL10) has been identified as a potent immunomodulatory cytokine that regulates inflammatory responses in the gastrointestinal tract. Although several single nucleotide polymorphisms (SNPs) in IL10 have been associated with the risk of colorectal cancer, their prognostic significance has not been determined. Two hundred and eightytwo colorectal cancer patients were genotyped for two candidate cancer-associated SNPs in IL10. The associations of these SNPs with distant metastasis-free survival and overall survival were evaluated by Kaplan-Meier analysis and Cox regression model. The minor homozygote GG genotype of IL10 rs3021094 was significantly associated with a 3.30-fold higher risk of death compared with the TT+TG genotypes (P = 0.011). The patients with IL10rs3021094 GG genotype also had a poorer overall survival in Kaplan-Meier analysis (log-rank P = 0.007) and in multivariate Cox regression model (P = 0.044) adjusting for age, gender,carcinoembryonic antigen levels, tumor differentiation, stage, lymphovascular invasion,and perineural invasion. In conclusion, our results suggest that IL10 rs3021094 might be a valuable prognostic biomarker for colorectal cancer patients.

Grain Size Effect on Multi-Stage Micro Deep Drawing of Micro Cup with Domed Bottom

Wen Ting Li,Ming Wang Fu,Ji Lai Wang,Bao Meng 한국정밀공학회 2016 International Journal of Precision Engineering and Vol.17 No.6

A two-stage micro deep drawing system was designed and developed to manufacture a micro cup with domed bottom. The copper blank was annealed at three different conditions to obtain different grain sizes in such a way to study the grain size effect on the deformation behavior and thickness variation of the micro part. To investigate the instantaneous effect and deformation behavior, finite element simulation was used to simulate the whole drawing process. It revealed that the fracture in the place with the thinnest thickness in the micro part drawn from a circle blank with residual stress induced in blanking can be easily happen and the deformation load in the first-stage decreases more than that in the second-stage with the increase of grain size. Moreover, the micro part with a larger grain size has more nonuniform thickness and severer thinning around the punch corner. The surface roughness at the bottom of micro part increases with the grain size. The surface roughness at the wall of it, however, decreases with the deformation stage mainly due to the ironing effect. The research promotes the understanding of grain size effect on multi-stage micro deep drawing and facilitates the development of microforming process.

Wen-Cheng J. Wei,Wen-Ting Hsu,Bang-Ying Yu 한양대학교 세라믹연구소 2006 Journal of Ceramic Processing Research Vol.7 No.3

The dissolution behavior of aqueous Pb(Zr,Ti) O3(PZT) suspensions were studied by Atomic Adsorption (AA) and Inductively Coupling Plasma (ICP) spectroscopies, specially emphasizing the change of solution acidity within pH 2 to 12, the effects of polymeric dispersant, and comparing with the dissolution behavior of PbO. The iso-electric-point (IEP) of a 2.0 wt % PZT solution was measured and compared to the minimal dissolution case (less than 10 ppm) to be in the range of pH 7 to 10. The effects of one dispersants, poly (α-N,N-dimethyl-N-acryloxyethyl) ammonium ethnate acrylamide (PMAA/DAAE) was investigated in comparison with a commercial anionic dispersant, an ammonium salt of polymethylacrylic acid (PMAAN). A possible dissolution model and the thickness of the Pb depletion zone on PZT particles are proposed based on the experimental observation.

Ting-Ting Li,Wenna Dai,Liwei Wu,Hao-Kai Peng,Xiayun Zhang,Bing-Chiuan Shiu,Jia-Horng Lin,Ching-Wen Lou 한국섬유공학회 2019 Fibers and polymers Vol.20 No.2

In order to deeply explore the fiber characteristics influencing on stab resistance of shear thickening fluid (STF)-impregnated fabrics, two different weaving fabrics, ultra-high molecular weight polyethylene (UHMWPE) fabric and Kevlar fabrics are saturate the various concentrations and particle size of STFs. Result shows that, SiO2/PEG-200 blends demonstrate quick shear-thickening property, and the critical shear rate lowers to 1.2-45 s-1 with higher concentration of 75 nm SiO2. STF concentration and particle size significantly affect spike puncture resistance property, but the knife stab resistance mainly depends on fiber characteristics. Comparatively, STF-UHMWPE composite fabrics exhibit better knife stab resistance but weaker spike puncture resistance than STF-Kevlar fabrics. This study can provide an optimization for structure design of stab resistance armors in the future.
