This study investigated the psychological effects of the long-term military intimidation imposed by the People’s Liberation Army (PLA) on the Taiwanese public. Online texts dating between 2016 and 2018 were mined and Russell’s (1980) semantic analysis was used to analyze the online discussions among the Taiwanese public regarding the PLA vessels and aircraft patrolling around Taiwan. The results showed that the PLA’s long-term encirclement patrols have generated numbness among the Taiwanese public. With regard to the Taiwanese government’s policy of disclosing information about such military encirclement patrols, the effects of proliferating this information were not significant, but have led to an increased sense of fear among the public. These ndings suggest that the effects of the PLA’s encirclement patrols around Taiwan are not determined by the PLA, but by the Taiwanese government’s policies regarding the disclosure of relevant information on encirclement patrols.

Objective: Choice of hysterectomy and adjuvant treatment for International Federation of Gynecology and Obstetrics (FIGO) 2009 stage II endometrioid endometrial cancer (EEC) is still controversial. Aims of this study were to evaluate survival benefits and adverse effects of different hysterectomies with or without adjuvant radiotherapy (RT), and to identify prognostic factors. Methods: The patients at 14 member hospitals of the Taiwanese Gynecologic Oncology Group from 1992 to 2013 were retrospectively investigated. Patients were divided into simple hysterectomy (SH) alone, SH with RT, radical hysterectomy (RH) alone, and RH with RT groups. Endpoints were recurrence-free survival (RFS), overall survival (OS), disease-specific survival (DSS), adverse effects and prognostic factors for survival. Results: Total of 246 patients were enrolled. The 5-year RFS, OS, DSS and recurrence rates for the entire cohort were 89.5%, 94.3%, 96.2% and 10.2%, respectively. Patients receiving RH had more adverse effects including blood loss (p<0.001), recurrent urinary tract infections (p=0.013), and leg lymphedema (p=0.038). Age over 50-year (HR=9.2; 95% confidence interval [CI], 1.2–70.9) and grade 3 histology (HR=7.28; 95% CI, 1.45–36.6) were independent predictors of OS. Grade 3 histology was an independent predictor of RFS (HR=5.13; 95% CI, 1.38–19.1) and DSS (HR=5.97; 95% CI, 1.06–58.7). Patients receiving adjuvant RT had lower locoregional recurrence (p=0.046), but no impact on survival. Conclusion: Different treatment modalities yield similar survival outcomes. Patients receiving SH with RT had lower locoregional recurrent with acceptable morbidity. Age and tumor grading remained significant predictors for survival among patients with FIGO 2009 stage II EEC.

Campylobacter jejuni is a prevalent foodborne pathogen worldwide. Human infection by C. jejuni primarily arises from contaminated poultry meats. Genes expressed in vivo may play an important role in the pathogenicity of C. jejuni. We applied an immunoscreening method, in vivo-induced antigen technology (IVIAT), to identify in vivo-induced genes during human infection by C. jejuni. An inducible expression library of genomic proteins was constructed from sequenced C. jejuni NCTC 11168 and was then screened using adsorbed, pooled human sera obtained from clinical patients. We successfully identified 24 unique genes expressed in vivo. These genes were implicated in metabolism, molecular biosynthesis, genetic information processing, transport, and other processes. We selected six genes with different functions to compare their expression levels in vivo and in vitro using real-time RT-PCR. The results showed that the selected six genes were significantly upregulated in vivo but not in vitro. In short, these identified in vivo-induced genes may contribute to human infection of C. jejuni, some of which may be meaningful vaccine candidate antigens or diagnosis serologic markers for campylobacteriosis. IVIAT may present a significant and efficient method for understanding the pathogenicity mechanism of Campylobacter and for finding targets for its prevention and control.
Gadolinium- and lead-containing functional terpolymers for low energy X-ray protection
Yu-Juan Zhang,Xin-Tao Guo,Chun-Hong Wang,Xiang An Lu,De-Feng Wu,Ming Zhang 한국원자력학회 2021 Nuclear Engineering and Technology Vol.53 No.12
By polymerization of gadolinium methacrylate (Gd (MAA)3), lead methacrylate (Pb(MAA)2) and methylmethacrylate (MMA), Gd and Pb were chemically bonded into polymers. The X-ray shielding performance was evaluated by Monte Carlo simulation method, and the results showed that the more metalfunctional organic monomer, the better the shielding performance of terpolymers. When the X-rayenergy is 65 keV, Gd (MAA)3-containing polymers have better shielding performance than Pb(MAA)2-containing polymers. Gd could compensate for the weak absorption region of Pb. Therefore, polymerscontaining both Gd and Pb enhanced shielding efficiency against X-ray in various low-energy ranges. Forobtaining terpolymers with uniform monomer compositions, the relationship between the monomercomposition of the terpolymers and the conversion level was optimized by calculating the reactivityratios. The value of reactivity ratios of r (Gd (MAA)3/Pb(MAA)2), r (Pb(MAA)2/Gd (MAA)3), r (Gd (MAA)3/MMA), r (MMA/Gd (MAA)3), r (Pb(MAA)2/MMA) and r (MMA/Pb(MAA)2) was 0.483, 0.004, 0.338, 2.508,0.255, 0.029. The terpolymers with uniform monomer composition could be obtained by controlling themonomer compositions or conversion levels. The results can provide new radiation protection materialsand contribute to the improvement in nuclear safety.

HER2-overexpressing breast cancers are characterized byfrequent distant metastasis and often develop resistance aftershort-term effective treatment with the monoclonal antibodydrug, trastuzumab. Here, we found that the oncogenic miRNA,miR-221, inhibited apoptosis, induced trastuzumab resistanceand promoted metastasis of HER2-positive breast cancers. Thetumor suppressor PTEN was identified as a miR-221 target;overexpression of PTEN abrogated the aforementionedmiR-221-induced malignant phenotypes of the cells. Thesefindings indicate that miR-221 may promote trastuzumabresistance and metastasis of HER2-positive breast cancers bytargeting PTEN, suggesting its role as a potential biomarker forprogression and poor prognosis, and as a novel target fortrastuzumab-combined treatment of breast cancers.[BMB Reports 2014; 47(5): 268-273]

A Novel LQG Controller of Active Suspension System for Vehicle Roll Safety
Shi-an Chen,Yu-meng Cai,Jian Wang,Ming Yao 제어·로봇·시스템학회 2018 International Journal of Control, Automation, and Vol.16 No.5
To improve vehicle roll safety during steering operation at high running speed, a new design approach for Linear Quadratic Gaussian (LQG) controller of active suspension system is proposed. Key steps of the new approach are as follows: 1) The front axle steered angle is written into a differential equation in accord with the minimum phase system and combines with the original system into the augmented system equation; 2) positive infinitesimals respectively including controls are added to the index; Thirdly, weights of the evaluating indicators of the LQG controller are determined by using analytic hierarchy process (AHP) and normalization methods based on vehicle motion statistics under the double-lane change maneuver as the typical steering maneuver. Performance comparisons are implemented between the active suspension system and the passive one under the double-lane change, slalom and fish-hook maneuvers. Results verify that the active suspension system with the proposed controller can achieve better vehicle roll safety and has a good adaptability under different steering maneuvers.
Drilling Temperature and Hole Quality in Drilling of CFRP/Aluminum Stacks Using Diamond Coated Drill
Chang-Ying Wang,Yu-Han Chen,Qinglong An,Xiaojiang Cai,Wei-Wei Ming,Ming Chen 한국정밀공학회 2015 International Journal of Precision Engineering and Vol. No.
Composite/metal stack materials, most often consisting of carbon fiber reinforced polymer (CFRP) composites and aluminum or titanium alloy (Al or Ti), have been widely used in the aviation industry. It is still a challenge to make holes on the composite/metal stack materials with high quality. This paper aims to investigate the influence of drilling parameters on the drilling of stack materials consisting of T800/X850 CFRP and 7075-T651 Al with regard to drilling force, drilling temperature, hole diameter and hole surface quality. Diamond coated drill bits with double point angles were employed in the drilling tests. The drilling temperature was measured utilizing a rotational motion temperature measuring system. It is indicated that maximum drilling temperature increases with the increase of spindle speed, while, it decreases with increasing feed rate. The thrust force and drilling temperature increase abnormally during drilling of the Al layer, which can be attributed to the evacuation difficulty of the long and flexible Al chips. It is found that sudden drops in the surface profile of CFRP are caused by the cavities owning to the resin degradation effects. The influences of different stack sequences on the drilling temperature and hole surface quality have also been discussed.

Relative to Chinese, as to Naxi Language, its corpus is very rare, its annotation is also difficult, and these factors make its Syntactic Analysis much too difficult. Aiming to the problem, in the paper, it is proposed a method for building Naxi Language Dependency Treebank based on Chinese-Naxi Language relationship alignment. Firstly, the corresponding words of Chinese-Naxi sentence pairs are aligned; then, the dependency grammar on Chinese sentences; Finally, some characteristics and rules of Naxi Language in itself being considered, the generated Chinese Dependency Tree is mapped to Naxi Sentence by using Chinese-Naxi Languages relationship alignment, as a result, Naxi Dependency Parsing Tree is generated. Experimental results show that: This approach can simplify the process of manual collection and annotation of Naxi Treebank, and save manpower and time to build the dependency treebank of Naxi Language.
