      • THE IMPACT OF HOTEL EMPLOYEES’ EMOTIONAL INTELLIGENCE ON CUSTOMER COMPLAINT HANDLING

        Ningning Xing,Lingling Xu,Henry Tsai 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

        This study examines the impact of emotional intelligence on the complaint handling process and outcome in the Chinese hotel setting. The results of the study indicate that the TARP model can be applied to China's hotel environment; “network evaluation” has become an important factor in assessing the severity of complaints. Besides, the negotiation and communication methods need to be adaptive in the context of Chinese consumer culture, and the complaints in the hotel environment should be handled immediately. Compared with the negative cases, the frequency of emotional intelligence application in positive cases is higher in every aspect of the TARP model. For the first time, the qualitative case study method is applied to similar research topics, and the application of various dimensions of emotional intelligence in hotel complaint handling process is thoroughly explored. This study not only has theoretical contributions but also serves as a reference for hotels to formulate a high-quality complaint handling standard operating procedure

        NIR light-powered halloysite-based nanomotors for CT imaging diagnosis and synergistic chemo-photothermal cancer therapy

        Xiaolei Zhang,Ziying Wang,Yangsai Lyu,Jia Li,Kun Song,Ningning Xing,Dickon H.L. Ng 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.116 No.-

        Near-infrared (NIR) light-powered nanomotors with active motion have attracted extensive attention inthe chemo-photothermal therapy of cancer. However, there are also some limitations such as complicatedsynthesis process, low permeability of drugs and viscous physiological environment. Herein, wedeveloped a facile route to synthesize novel NIR light-powered DOX/Au-m-HTAS nanomotor based onnatural halloysite (HNTs) for active chemo-photothermal therapy. Such nanomotor exhibited NIR lightcontrolled on/off motion with a maximum speed of 64.5 lm/s. Owing to the synergetic NIR lightpoweredmotion and chemo-photothermal therapy, DOX/Au-m-HTAS nanomotor could effectivelyadhere tumor cells, leading to deeper cell penetration, higher cellular uptake, and better ablation oftumor cells. Meanwhile, DOX/Au-m-HTAS nanomotors also had enhanced ability for CT imaging of localtumor, demonstrating the enhanced anticancer efficiency. This strategy provided a new insight into thechemo-photothermal synergistic therapy of tumors.

        Prediction of Screw Loosening After Dynamic Pedicle Screw Fixation With Lumbar Polyetheretherketone Rods Using Magnetic Resonance Imaging-Based Vertebral Bone Quality Score

        Guozheng Jiang,Luchun Xu,Yukun Ma,Jianbin Guan,Yongdong Yang,Wenqing Zhong,Wenhao Li,Shibo Zhou,JiaWei Song,Ningning Feng,Ziye Qiu,Zeyu Li,YiShu Zhou,Letian Meng,Yi Qu,Xing Yu 대한척추신경외과학회 2024 Neurospine Vol.21 No.2

        Objective: To investigate the correlation between magnetic resonance imaging-based vertebral bone quality (VBQ) score and screw loosening after dynamic pedicle screw fixation with polyetheretherketone (PEEK) rods, and evaluate its predictive value. Methods: A retrospective analysis was conducted on the patients who underwent dynamic pedicle screw fixation with PEEK rods from March 2017 to June 2022. Data on age, sex, body mass index, hypertension, diabetes, hyperlipidemia history, long-term smoking, alcohol consumption, VBQ score, L1–4 average Hounsfield unit (HU) value, surgical fixation length, and the lowest instrumented vertebra were collected. Logistic regression analysis was employed to assess the relationship between VBQ score and pedicle screw loosening (PSL). Results: A total of 24 patients experienced PSL after surgery (20.5%). PSL group and nonPSL group showed statistical differences in age, number of fixed segments, fixation to the sacrum, L1–4 average HU value, and VBQ score (p < 0.05). The VBQ score in the PSL group was higher than that in the non-PSL group (3.56 ± 0.45 vs. 2.77 ± 0.31, p < 0.001). In logistic regression analysis, VBQ score (odds ratio, 3.425; 95% confidence interval, 1.552–8.279) were identified as independent risk factors for screw loosening. The area under the receiver operating characteristic curve for VBQ score predicting PSL was 0.819 (p < 0.05), with the optimal threshold of 3.15 (sensitivity, 83.1%; specificity, 80.5%). Conclusion: The VBQ score can independently predict postoperative screw loosening in patients undergoing lumbar dynamic pedicle screw fixation with PEEK rods, and its predictive value is comparable to HU value.
