포스트 코로나 시대에는 사람의 생활방식이 바뀌면서 인터넷 쇼핑으로 단순히 적합한 제품을 선택하고, 기대한 욕구를 충족시키기 위한 것뿐만 아니라, 중요한 레저 오락 방식이며, 각 쇼핑 플랫폼을 통해 원하는 상품을 구매하는 것보다 소비자들은 쇼핑 플랫폼이 제공하는 서비스에 대해서도 중시하는 것을 알 수 있다. 4차 산업혁명으로 인공지능, 빅데이터 등 기술을 활용하여 소비자의 취향과 선호에 맞춰 상품을 추천해주는 상품추천 서비스가 확산되고 있다. 이어 본 연구목적은 첫째, 중국 소비자를 대상으로 조사하여 타오바오 쇼핑 플랫폼에서 제공한 추천 서비스의 특성이 만족도에 대한 어떠한 영향을 미치는지, 그리고 만족도는 지속사용의도에 어떠한 영향을 미치는지를 검증할 것이다. 둘째, 제품 유형에 따른 추천 서비스 특성이 만족도에 차이가 있는지를 살펴볼 것이다. 연구 결과에 따르면 첫째, 추천 서비스의 특성이 만족도에 부분적으로 영향을 미쳤다. 즉 개인화, 정확성, 신뢰성은 만족도에 긍정적으로 영향을 미치는 것으로 나타나 채택되었다. 하지만 의외성은 만족도에 긍정적인 영향을 미치지 않은 것으로 나타나 가설이 기각되었다. 둘째 만족도는 지속 사용 의도에 긍정적으로 영향을 미치는 것으로 나타나 채택되었다. 마지막으로 제품 유형은 경험재와 탐색재로 구분하여 개인화 추천 서비스의 개인화 특성, 의외성이 제품 유형에 따라 만족도에 차이가 있는 것으로 결과를 밝혔다. In the post-COVID-19 era, with the changes in people’s lifestyles, online shopping is not only for choosing the right products and meeting expectations, but also an important way of leisure and entertainment. Consumers not only buy the products they want through various shopping platforms, but they also value the services provided by the shopping platforms. With the 4th industrial revolution, product recommendation services that use technologies such as artificial intelligence and big data to recommend products according to consumer tastes and preferences are spreading. Next, the purpose of this study is to first examine how the characteristics of the recommended service provided by the Taobao shopping platform affect satisfaction by surveying Chinese consumers and how satisfaction affects their intention to continue using it. Second, we will examine whether there is a difference in satisfaction with the recommended service characteristics according to product type. According to the research results, firstly, the characteristics of the recommendation service partially affect the satisfaction. Specifically, personalization, accuracy, and reliability were found to positively influence satisfaction. However, the serendipity was rejected because serendipity had no positive effect on satisfaction. Second, satisfaction was found to have a positive effect on intention to continue using and was therefore adopted. Finally, the product types are divided into experience products and search products. The results show that the personalization and serendipity of personalized recommendation services have different satisfaction due to different product types.

Sheng-Mou Hsiao,Pei-Chi Wu,Ting-Chen Chang,Chi-Hau Chen,Ho-Hsiung Lin 대한배뇨장애요실금학회 2019 International Neurourology Journal Vol.23 No.1

Purpose: To identify factors predicting the presence of overactive bladder syndrome (OAB)-wet, compared with OAB-dry. Methods: Between September 2007 and September 2013, the medical records of 623 women with OAB who completed a 3-day bladder diary and underwent urodynamic studies in a medical center were retrospectively reviewed. OAB-wet was diagnosed in patients who complained of at least one episode of urgency incontinence in the previous month; otherwise, OABdry was diagnosed. Multivariable logistic regression analysis was used to predict the presence of OAB-wet. Results: Age (odds ratio [OR], 1.05; P<0.001), maximal flow rate (Qmax) (OR,1.06; P<0.001), voided volume (OR, 0.996; P=0.001), detrusor pressure at maximal flow rate (PdetQmax) (OR, 1.02; P=0.003), urgency episodes (OR, 1.04; P<0.001) and urodynamic stress incontinence (OR,1.78; P=0.01) were independent predictors for the presence of OAB-wet vs. OABdry. If we use bladder contractility index as a variable for multivariable logistic regression analysis, bladder contractility index (OR, 1.012; P<0.001) become an independent predictor for OAB-wet. Conclusions: A smaller bladder capacity and more frequent urgency episodes were predictors of OAB-wet, and the above findings indicate that OAB-wet and OAB-dry might be a continuum of OAB. Old age, high Qmax, high PdetQmax and urodynamic stress incontinence were also predictors for OAB-wet, and the above results reveal that OAB-wet and OAB-dry have partially different clinical and urodynamic features. Further studies might be performed to elucidate whether different treatment strategies between OAB-dry and OAB-wet can improve treatment efficacy.

Chen, Wei-Sheng,Chung, Yi-Fan,Tien, Ko-Wei The Korean Institute of Resources Recycling 2020 資源 리싸이클링 Vol.29 No.1

Recovery of gallium and indium from waste light emitting diodes has been emphasized gradually owing to high content of gallium and indium. This study was established the recovery of gallium (Ga³⁺) and indium (In³⁺) from waste gallium nitride was contained in waste light-emitting diodes. The procedure was divided into the following steps; characteristic analysis, alkaline roasting, and leaching. In characteristic analysis part, the results were used as a theoretical basis for the acid leaching part, and the chemical composition of waste light emitting diodes is 70.32% Ga, 5.31% Si, 2.27% Al and 2.07% In. Secondly, with reduction of non-metallic components by alkaline roasting, gallium nitride was reacted into sodium gallium oxide, in this section, the optimal condition of alkaline roasting is that the furnace was soaked at 900℃ for 3 hours with mixing Na₂CO₃. Next, leaching of waste light emitting diodes was extremely important in the process of recovery of gallium and indium. The result of leaching efficiency was investigated on the optimal condition accounting for the acid agent, concentration of acid, the ratio of liquid and solid, and reaction time. The optimal condition of leaching procedures was carried out for 2.0M of HCl liquid-solid mass ratio of 30 ml/g in 32minutes at 25℃ and about 96.88% Ga and 96.61% In were leached.

Sheng Zou,Xi-Yuan Chen,Hong Zhang,Yao Chen,Jian-cheng Fang 한국광학회 2015 Current Optics and Photonics Vol.19 No.4

A novel method to measure the scale factor for the all-optical atomic spin inertial measurement device(ASIMD) is demonstrated in this paper. The method can realize the calibration of the scale factor by aself-consistent method with small errors in the quiescent state. At first, the matured IMU (inertialmeasurement unit) device was fixed on an optical platform together with the ASIMD, and it has beenused to calibrate the scale factor for the ASIMD. The results show that there were some errors causingthe inaccuracy of the experiment. By the comparative analysis of theory and experiment, the ASIMD wasunable to keep pace with the IMU. Considering the characteristics of the ASIMD, the mismatch betweenthe driven frequency of the optical platform and the bandwidth of the ASIMD was the major reason. Anall-optical atomic spin magnetometer was set up at first. The sensitivity of the magnetometer is ultra-high,and it can be used to detect the magnetization of spin-polarized noble gas. The gyromagnetic ratio ofthe noble gas is a physical constant, and it has already been measured accurately. So a novel calibrationmethod for scale factor based on the gyromagnetic ratio has been presented. The relevant theoreticalanalysis and experiments have been implemented. The results showed that the scale factor of the devicewas 7.272 V/°/s by multi-group experiments with the maximum error value 0.49%

Chen, Wei-Sheng,Chen, Yen-Jung,Yueh, Kai-Chieh The Korean Institute of Resources Recycling 2020 資源 리싸이클링 Vol.29 No.2

With rapid increasing production and installation, recycling of photovoltaic modules has become the main issue. According to the research, the accumulation of waste modules will reach to 8600 tons in 2030. Moreover, Crystalline-silicon (c-Si) Photovoltaic modules account for more than 90% of the waste. C-Si PV modules contain 1.3% of weight of photovoltaic ribbon inside which contains the most of lead, tin and copper in the PV modules, which would cause environmental and humility problem. This study provided a valuable metal separation process for PV ribbons. Ribbons content 82.1% of Cu, 8.9% of Sn, 5.2% of Pb, and 3.1% of Ag. All of them were leached by 3M of hydrochloric acid in the optimal condition. Ag was halogenated to AgCl and precipitated. Cu ion was extracted and separated from Pb and Sn by Lix984N then stripped by 3M H2SO4. The effect of the optimal parameters of extraction was also studied in this essay. The maximum extraction efficiency of Cu ion was 99.64%. The separation condition of Pb and Sn were obtained by adjusting the pH value to 4 thought ammonia to precipitate and separate Pb and Sn. The recovery of Pb and Sn can reach 99%.

Spatial Distribution of Lead Iodide and Local Passivation on Organo-Lead Halide Perovskite

Chen, Sheng,Wen, Xiaoming,Yun, Jae S.,Huang, Shujuan,Green, Martin,Jeon, Nam Joong,Yang, Woon Seok,Noh, Jun Hong,Seo, Jangwon,Seok, Sang Il,Ho-Baillie, Anita American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.7

<P>We identify nanoscale spatial distribution of PbI2 on the (FAPbI(3))(0.85)(MAPbBr(3))(0.15) perovskite thin film and investigate the local passivation effect using confocal based optical microscopy of steady state and time-resolved photoluminescence (PL). Different from a typical scanning electron microscope (SEM) morphology study, confocal based PL spectroscopy and microscopy allow researchers to map the morphologies of both perovskite and PbI2 grains simultaneously, by selectively detecting their characteristic fluorescent bands using band-pass filters. In this work, we compare the perovskite samples without and with excess PbI2 incorporation and unambiguously reveal PbI2 distribution for the PbI2-rich sample. In addition, using the nanoscale time-resolved PL technique we show that the PbI2-rich regions exhibit longer lifetime due to suppressed defect trapping, compared to the PbI2-poor regions. The measurement on the PbI2-rich sample indicates that the passivation effect of PbI2 in perovskite film is effective, especially in localized regions. Hence, this finding is important for further improvement of the solar cells by considering the strategy of excess PbI2 incorporation.</P>

Chen, Yu-Sheng,Bo, Xiao-Bo,Gu, Da-Yong,Gao, Wei-Dong,Sheng, Wei-Zhong,Zhang, Bo Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.1

Background: The aim of this study was to establish the feasibility and efficiency of different pelvic drainage routes after laparoscopic abdominoperineal resection (LAPR) for rectal cancer by assessing short-term outcomes. Materials and Methods: Clinicopathological data of 76 patients undergoing LAPR for very low rectal cancer were reviewed retrospectively between June 2005 and June 2014. Outcomes were evaluated considering short-term results. Results: Of 76 relevant patients at our institution in the period of study, trans-perineal drainage of the pelvic cavity was performed in 17 cases. Compared with the trans-perineal group, the length of hospital stay was shorter in the trans-abdominal group, while the duration of drainage and the infection rates of the perineal wounds between two groups showed no significant differences. Conclusions: The outcomes of this study suggest that trans-abdominal drainage of pelvic cavity is a reliable and feasible procedure, the duration of drainage, infection rates and the healing rates of the perineal wounds being acceptable. Trans-abdominal drainage has a more satisfactory effect after laparoscopic abdominoperineal resection for rectal carcinoma.
