To determine the proteomic response to UV irradiation, two cultivars, i.e., Lemont (UV tolerant) and Dular (UV sensitive), were exposed to natural and enhanced ultraviolet-B (UV-B) irradiation for 1, 7, and 14 days, and two-dimensional gel electrophoresis in combination with mass spectrometry (MS) and bioinformatics were used to compare the different proteomic responses in the leaves of the two cultivars. Thirty-nine proteins were up- or downregulated following the UV-B treatments. Among them, 30 increased or decreased more than 1.5-fold in abundance. They were further tested by using matrix-assisted laser desorption/ionization time of flight MS and performed a database search. Twentyfour proteins were thus identified. These identified proteins were mostly upregulated in Lemont, whereas only 14 of them upregulated in Dular. Nine proteins involved in glycometabolism and fatty acid metabolisms, signal transduction, and protein synthesis and folding in Dular were not changed. These results suggest that there was a complex regulative mechanism on the proteomes in rice leaves upon UV-B exposure.
The Determinants of South Korea’s Trade Balance: A Cointegrating Regression Approach
Ting-Huan Chang,Jun-De Lee,Yi-Hsien Wang 한국무역학회 2012 Journal of Korea trade Vol.16 No.3
This paper examines the key determinants of South Korea’s trade balance using three fully efficient cointegrating regression methods. We find that the trade balance, foreign income, money supply, real effective exchange rate, and domestic income are cointegrated. Consistent with the Marshall-Lerner condition, appreciation in the real effective exchange rate is negatively related to the trade balance. Our results have important implications for using exchange rate policy as a device to achieve trade balance.
THE INFLUENCES OF COOLNESS AND AFFINITY OF SERVICE ROBOTS ON CUSTOMERS’ BEHAVIORAL INTENTIONS
Sue-Ting Chang,Sheng-Hshiung Tsaur,Chu-Cheng Chang,Tien-Cheng Han 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07
The outbreak of COVID-19 has brought significant changes to today’s life. Human contact is regarded as a source of risk. Thus, the low-contact services provided by service robots have gained more attention in the hospitality industry. However, a relatively smaller proportion of empirical research exists about service robots on the consumer side. Moreover, technology acceptance theories were mostly used in the adoption of new technology products, but the psychological aspects of consumers were rarely explored. Therefore, the stimulus- organism-response model (SOR model) was applied to explore consumers’ acceptance of adopting service robots and to understand what factors will successfully stimulate consumers’ subsequent value and behavioral responses. Furthermore, we investigated the relationship among stimulus (coolness and affinity), organism (utilitarian value and hedonic value) and response (intention to use and word-of-mouth recommendation). This study used convenience sampling and tested the hypotheses with SPSS and Smart PLS.

FePO4 coated Li5Cr7Ti6O25 nanocomposites are synthesized according to a simple sol–gel method followingby a calcination procedure. XRD and Rietveld refinement result indicate that FePO4 decorating doesnot change the crystal structure and lattice parameters of Li5Cr7Ti6O25. SEM and TEM prove that the particlesize of all sample are evenly distributed in the 50–100 nm range. Both energy dispersion spectroscopymapping and HRTEM indicate the existence of FePO4 on the surface of Li5Cr7Ti6O25, whichprovides a good conductive contact. CV and EIS exhibit that FePO4 (3 wt%) coated Li5Cr7Ti6O25 materialhas lower polarization, larger Li+ diffusion coefficient and higher conductivity than other pureLi5Cr7Ti6O25 and other FePO4 coated Li5Cr7Ti6O25 composites. Therefore, FePO4 (3 wt%) coatedLi5Cr7Ti6O25 anode material displays the highest charge and discharge capacity at each rate. Theenhanced electrochemical performance of FePO4-coated Li5Cr7Ti6O25 result from the enhanced lithiumion and electron transfer kinetics. The pristine Li5Cr7Ti6O25 only shows a specific capacity of197 mAh g 1 at 500 mA g 1 after 100 cycles, but FePO4 (3 wt%)-coated Li5Cr7Ti6O25 achieves a highcapacity of 237.9 mAh g 1. Therefore, the FePO4 coating can be regarded as a promising strategy toimprove the electrochemical properties of Li5Cr7Ti6O25.

To evaluate the relation between smoking, alcohol drinking and risk of breast cancer in Chinese women, we conducted a case-control study with 669 cases and 682 population-based controls in Jiangsu Province of China. A structured questionnaire was used to elicit detailed information. Unconditional logistic regression analysis was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs). The results revealed that smoking, whether active or passive through the husband, was related to increased risk of breast cancer. The ORs (adjusted for age, menopausal status, educational levels, occupation, body mass index and income) were 3.55 (95%CI: 1.27-9.91) for active smoking and 1.47 (95%CI: 1.18-1.84) for passive smoking from husbands, respectively. A significant positive relationship was observed between breast cancer risk and the degree of husbands' smoking. There were significant increase trend in ORs with the daily smoked number of cigarettes of husbands, the passive smoking years from husbands and the pack-years of husbands' smoking (trend test: p=0.00003, 0.00013 and 0.0001, respectively). Alcohol consumption was also found to be a risk factor. The findings of this study in particular suggest that husbands' smoking increases risk of breast cancer in Chinese women.
Evaluating the effects of programs for reducing achievement gaps: a case study in Taiwan

Considering that achievement gaps have become a serious educational problem worldwide, the Ministry of Education in Taiwan has been addressing a series of policies to reduce achievement gaps, but the effect of these policies has not yet been carefully examined. Therefore, the present study investigated current educational policies, achievement gap phenomenon, and its changing trends in the use of national standardized tests in Taiwan and evaluated the degree to which these policies are reducing the achievement gaps among Taiwanese students. Junior high school graduates who took the high school entrance examination between 2004 and 2010 were recruited to examine the associations between their academic achievements and variables such as socioeconomic status (SES), ethnicity, and school district. Time series analyses were conducted to determine the longitudinal trends for the achievement gaps. The results revealed that achievement gaps are decreasing among different ethnicities, but they are increasing among different SESs and school districts. These findings demonstrate some positive effects of the educational policies introduced in Taiwan, but also the need for further modification and precise implementation of these policies. Suggestions for implementing educational programs and policies to reduce achievement gaps are also presented.

Purpose In 2013, medical schools in Taiwan implemented a 6-year medical program that replaced the previous 7-year medical education program. The postgraduate year (PGY) program was also extended from 1 year to 2 years. The new program is characterized by diversified teaching, integration of medical skills, a system-oriented curriculum, and the implementation of primary care and clinical thinking training. The purpose of this study was to examine whether postgraduate residents who learned under the new program have better patient care skills than those who learned under the previous program. Methods Of 101 residents in the PGY program at Taipei Veterans General Hospital, 78 were trained in the 6-year program, while 23 were trained in the 7-year program. During the PGY training, 2 objective structured clinical examinations (OSCEs) were used to evaluate clinical reasoning, communication skills, and procedural skills at the beginning of the training and after 11 months of training, respectively. The scores of each OSCE and the rate of improvement of the pre- and post-tests were analyzed. Results Residents trained in the new program scored higher on clinical reasoning (P<0.001) and the total scores of the 3 tested skills (P=0.019) on the pre-test. In terms of improvement, residents educated in the previous system improved more in clinical reasoning than those educated in the new education system. Conclusion The new medical education program, which emphasizes clinical thinking, improved residents’ clinical skills. The PGY program was effective in improving the clinical performance of residents who were educated in the previous system.
