Talents First!: Wu Ta-you and Science Policy Infrastructures in the Republic of China (1927-1970)
( Chang Kuo-hui ),( Gary Lee Downey ),( Shih Bono Po-jen ) 한국과학사학회 2020 한국과학사학회지 Vol.42 No.2
A main theme in the history of science policy in Taiwan concerns the positioning of science infrastructures in nation building and rapid economic growth. This article calls attention to another evolving initiative in science policy in the Republic of China (ROC), one that emphasized the production of talents who could become societal leaders, including by working for and within government. We trace the emergence of this initiative through the career of Wu Ta-you, who grew up in mainland China, earned his Ph.D. in the United States, and worked on the margins of reconstruction during the 1930s. Through the 1950s, he played a leadership role advocating for long-term planning to develop fundamental researchers in science in Taiwan. His moment appeared to come in 1967 when he became the president’s chief science adviser. His efforts to develop science talents were soon displaced, however, by emerging shorter-term initiatives to support the military and industry. Clearly not contributing as an instrumental technocrat nor a proponent for autonomous basic research, was he attempting to combine the identity of a scientist with that of the Chinese scholar-official? By taking science policy in a different direction, the ROC, in Wu’s terms, remained stuck on the surface of science.

The study was inspired by the specialized facial masks made of rayon non-woven fabrics which contained collagen peptides for improving moisturizing function. This study explored the moisturizing function of a rayon fabric containing collagen peptides extracted from tilapia fish scales under various conditions of relative humidity. This research had implications for the development of clothing that can prevent dry skin. A two-stage nested design experiment was adopted. The first-stage factor such as the fabric has two levels and the second-stage factor such as the relative humidity with three levels nested under each level of the first-stage factor. Preliminary results indicated that introducing a new variable (i.e., fabric moisturizing value, which combines the moisture regains of adsorption and desorption) would be useful. The moisturizing value of the novel rayon fabric and regular rayon fabric increased with the increase in relative humidity, and moisturizing effect of the novel rayon fabric with collagen peptides was better than that of the regular rayon fabric. Therefore, the novel rayon fabric may be suitable for preventing dry skin in winter.

Osteoporosis and its associated fragility fractures are becoming a severe burden in the healthcare system globally. In the Asian-Pacific (AP) region, the rapidly increasing in aging population is the main reason accounting for the burden. Moreover, the paucity of quality care for osteoporosis continues to be an ongoing challenge. The Fracture Liaison Service (FLS) is a program promoted by International Osteoporosis Foundation (IOF) with a goal to improve quality of postfracture care and prevention of secondary fractures. In this review article, we would like to introduce the Taiwan FLS network. The first 2 programs were initiated in 2014 at the National Taiwan University Hospital and its affiliated Bei-Hu branch. Since then, the Taiwan FLS program has continued to grow exponentially. Through FLS workshops promoted by the Taiwanese Osteoporosis Association (TOA), program mentors have been able to share their valuable knowledge and clinical experience in order to promote establishments of additional programs. With 22 FLS sites including 11 successfully accredited on the best practice map, Taiwan remains as one of the highest FLS coverage countries in the AP region, and was also granted the IOF Best Secondary Fracture Prevention Promotion award in 2017. Despite challenges faced by the TOA, we strive to promote more FLS sites in Taiwan with a main goal of ameliorating further health burden in managing osteoporotic patients.

Purpose: Cancer cells develop acquired resistance induced by chemotherapeutic drugs. In this study, we investigated the effects of brief treatment with cytotoxic drugs on the phenotype of breast cancer cells. Methods: Breast cancer cells MCF7 and BT-474 were briefly treated with paclitaxel or doxorubicin. Clonogenic, migration, and invasion assays were performed on the treated cells. Western blot analysis and RhoA activity assay were also performed. Results: Breast cancer cells when briefly treated with paclitaxel or doxorubicin showed reduced clonogenic ability. Doxorubicin, but not paclitaxel, augmented cell migration and invasion. The invasion-promoting effects of doxorubicin were lost when the two drugs were sequentially used in combination. Myosin light chain (MLC) 2 phosphorylation and RhoA activity were upregulated by doxorubicin and downregulated by paclitaxel. Pretreatment with RhoA inhibitors abolished the migration- and invasion-promoting effects of doxorubicin. Conclusion: Doxorubicin activates the RhoA/MLC pathway and enhances breast cancer cell migration and invasion. Therefore, this pathway might be explored as a therapeutic target to suppress anthracycline-enhanced tumor progression.
Load Voltage Tracking of Electric Power Systems by Using Backstepping Design

A backstepping controller design is proposed for the load voltage tracking of electric power system. It is known that a power system might exhibit saddle-node and Hopf bifurcations as load change, which can lead to the appearance of dynamic and/or static voltage collapses. The output tracking control laws are proposed for the load voltage regulation of the electric power system via backstepping control scheme. The numerical simulations demonstrate that the proposed control scheme not only could provide the regulation of the load voltage but also prevent and/or delay the appearance of bifurcation phenomena and chaotic behavior.

Background/Aims: Real-world studies assessing the effectiveness and safety of sofosbuvir/velpatasvir (SOF/VEL) plus ribavirin (RBV) for Child-Pugh B/C hepatitis C virus (HCV)-related cirrhosis are limited. Methods: We included 107 patients with Child-Pugh B/C HCV-related cirrhosis receiving SOF/VEL plus RBV for 12 weeks in Taiwan. The sustained virologic response rates at off-treatment week 12 (SVR<sub>12</sub>) for the evaluable population (EP), modified EP, and per-protocol population (PP) were assessed. The safety profiles were reported. Results: The SVR<sub>12</sub> rates in the EP, modified EP and PP were 89.7% (95% confidence interval [CI], 82.5-94.2%), 94.1% (95% CI, 87.8-97.3%), and 100% (95% CI, 96.2-100%). Number of patients who failed to achieve SVR<sub>12</sub> were attributed to virologic failures. The SVR<sub>12</sub> rates were comparable regardless of patient characteristics. One patient discontinued treatment because of adverse events (AEs). Twenty-four patients had serious AEs and six died, but none were related to SOF/VEL or RBV. Among the 96 patients achieving SVR<sub>12</sub>, 84.4% and 64.6% had improved Child-Pugh and model for endstage liver disease (MELD) scores. Multivariate analysis revealed that a baseline MELD score ≥15 was associated with an improved MELD score of ≥3 (odds ratio, 4.13; 95% CI, 1.16-14.71; P=0.02). Patients with chronic kidney disease (CKD) stage 1 had more significant estimated glomerular filtration rate declines than patients with CKD stage 2 (-0.42 mL/min/1.73 ㎡/month; P=0.01) or stage 3 (-0.56 mL/min/1.73 ㎡/month; P<0.001). Conclusions: SOF/VEL plus RBV for 12 weeks is efficacious and well-tolerated for Child-Pugh B/C HCV-related cirrhosis. (Clin Mol Hepatol 2021;27:575-588)

Background: Depressive disorders (DD) affect not only mood and behavior but also various physical functions. Traditional Chinese medicine (TCM) has been shown to have some benefits in treating DD. However, one formula or one single herb might be not show high efficacy when used to treat depression. Thus, this study aimed to examine the core prescription pattern of Chinese herbal medicine (CHM) among patients with DD in Taiwan as a reference for related research and clinical applications. Methods: All patients, who had been diagnosed with major depressive disorder or minor depression or dysthymia without any other baseline diseases and had at least one CHM outpatient clinical visit from 2002 to 2011, were extracted from three randomly sampled cohorts, namely the 2000, 2005 and 2010 cohorts of the National Health Insurance Research Database (NHIRD) of Taiwan. The collected data was analyzed to explore the patterns of herbal products. Results: There were 197,146 patients with a diagnosis of DD and of these 1806 subjects had only a diagnosis of DD and utilized CHM. The most common formula was Gan-Mai-Da-Zao-Tang (12.19%), while Suan-Zao-Ren (3.99%) was the most commonly prescribed single herb. The core pattern of prescriptions consisted of a combination of Gan-Mai-Da-Zao-Tang, Jia-Wei-Xiao-Yao-San, Chai-Hu-Jia-Long-Gu-Mu-Li-Tang, He-Huan-Pi, Yuan-Zhi and Shi-Chang-Pu. Conclusions: This study describes the CHM core prescription pattern used to treat patients in Taiwan with DD and it is a potential candidate for study in future pharmacological or clinical trials targeting DD.
