Shu-Yuan Liang,Wei-Wen Wu,Chiu-Ya Kuo,Yu-Ying Lu 한국간호과학회 2015 Asian Nursing Research Vol.9 No.4

Purpose: The purpose of this study was to develop and preliminarily evaluate the reliability and validity of the Symptom-Management Self-Efficacy ScaleeBreast Cancer (SMSES-BC) related to chemotherapy. Methods: The study included three stages. This paper presents the results of stage 2 and stage 3. In total, 34 items in the SMSES-BC were found during stage 1 from qualitative findings, a literature review, and expert suggestions; the 34 items were used for the psychometric properties test. Test-retest reliability and Cronbach a were assessed in the first sample, which included 45 participants for the pilot test (stage 2). The second sample, which included 152 patients, was used to assess the construct validity and concurrent validity (stage 3). Results: The pilot test results revealed a test-retest reliability of .73 (p < .001) and Cronbach a coefficient of .96 for the total scale. Three factors (managing chemotherapy-related symptoms, acquiring problem solving, and managing emotional and interpersonal disturbances) were identified from exploratory factor analysis. Correlation coefficient r was .40 (p < .001), which supported the association between SMSES-BC and the General Self-Efficacy Scale for concurrent validity. Conclusions: The study results demonstrate acceptable reliability and validity for the SMSES-BC that was developed for measuring symptom-management self-efficacy related to chemotherapy for patients with breast cancer. This study suggests further research to validate the construct of the SMSES-BC.

Robust Control for Bidirectional Stabilization System With Time Delay Estimation

Shu-sen Yuan,Wen-xiang Deng,Jian-yong Yao,Guo-lai Yang 제어·로봇·시스템학회 2024 International Journal of Control, Automation, and Vol.22 No.4

In this paper, to address the problem of high precision tracking control for bidirectional stabilization system of marching all-electric tank, a continuous nonsingular terminal sliding mode (CNTSM) control method combined with time delay estimation (TDE) technique is presented. First, the nonlinear mathematical model of the bidirectional stabilization system with consideration of actuator dynamics is established. Second, the TDE method is invoked to estimate the unknown system dynamics and provide fascinating model-free structures. Then, a CNTSM surface and a fast TSM reaching law are constructed to guarantee finite-time convergence. The proposed controller no longer requires system dynamics benefiting from TDE, while ensuring high accuracy, fast convergence and good robustness against lumped uncertainty due to the CNTSM manifold and the fast TSM reaching law. The stability and finite-time convergence of the closed-loop system are analyzed applying Lyapunov theory. Extensive comparative results verify the superiority with the proposed controller.

Although Dangyuja (Citrus grandis Osbeck) exhibits anti-inflammatory and anticancer activities, its molecular targets and pathways, especially in human prostate cancer cells, are not fully understood. In this study, the antiproliferative effect of Dangyuja leaves through the signal transducer and activator of transcription (STAT) 3 signaling pathway was investigated in human prostate carcinoma DU145 cells. The solvent fractions (n-hexane, chloroform, ethyl acetate, and nbutanol)were obtained from a crude extract (80% methanol extract) of Dangyuja leaves. We first found that the chloroform fraction of Dangyuja leaves (DCF) was the most cytotoxic against DU145 cells. DCF inhibited constitutive STAT3 activation through blocking upstream Janus-like kinase 2 and c-Src. Consistent with STAT3 inactivation, DCF down-regulated the expression of STAT3 target genes, including bcl-2, bcl-xl, and cyclin D1; this correlated with the suppression of proliferation,the accumulation of cell cycle at the sub-G1 phase, and the induction of apoptosis. Furthermore, DCF exerted a relatively minor effect on the growth of human prostate noncancerous RWPE-1 cells. Nobiletin, a major active constituent of DCF,could induce apoptosis via the suppression of constitutive STAT3 activation. Overall, our results indicate that the antiinflammatory and anticancer activities previously assigned to DCF may be mediated partially through the suppression of the STAT3 signaling.

CASPT2 Study on the Low-lying Electronic States of 1,3,5-C6H3Cl3 + Ion

Shu-Yuan Yu,Cheng-Gen Zhang,Shu-Jun Wang 대한화학회 2014 Bulletin of the Korean Chemical Society Vol.35 No.5

The multiconfiguration second-order perturbation theory (CASPT2) and complete active space self-consistent field (CASSCF) methods were employed to calculate the geometries and energy levels for the low-lying electronic states of 1,3,5-C6H3Cl3 + ion. The CASPT2 values for the 1,3,5-C6H3Cl3 + ion were in reasonable agreement with the available experimental values. The current calculations augmented previous theoretical investigations on the ground state and assigned the low-lying excited electronic states of the 1,3,5-C6H3Cl3 + ion. The Jahn-Teller distortion in the excited electronic state for the 1,3,5-C6H3Cl3 + ion were reported for the first time.

Shu-Yuan Liang,Hui-Chun Liu,Yu-Ying Lu,Shu-Fang Wu,Ching-Hui Chien,Shiow-Luan Tsay 한국간호과학회 2020 Asian Nursing Research Vol.14 No.1

Purpose: The purpose of this study was to assess the amount of variance in the coping strategies of patients with brain tumors that could be accounted for by resilience. Methods: This cross-sectional survey involved 95 patients who had experienced surgical, chemotherapy, or radiotherapy therapies for their brain tumors at least 1 month before data collection. The investigator collected data using the scales of the Ways of Coping Checklist-Revised and Resilience Scale. Data were analyzed using descriptive statistics, t tests, analysis of variance, Pearson product–moment correlation, and hierarchical multiple regression. Results: The results revealed that resilience was significantly positively associated with patients' problem-focused coping (r = .65, p < .001) and total coping (r = .49, p < .001). In addition, resilience accounted for 27% (R2inc = .27, p < .001) and 16% (R2inc = .16, p < .001) of the distinct variances in predicting patients’ problem-focused coping and total coping. Conclusion: The current results provide evidence to support the importance of resilience in shaping the coping strategies of relevant patients. As resilience shows a crucial element in patient coping with brain tumors, health team members should develop and employ appropriate strategies to improve the resilience of patients with brain tumors.

Study on the preparation of nano-flaky anatase titania layer and their photovoltaic application

Shu-Yuan Wu,Wen-Chi Lo,Keh-Chang Chen,Ju-Liang He 한국물리학회 2010 Current Applied Physics Vol.10 No.2

Titania (TiO2), known to have wide energy band gap, can greatly absorb dye if specific surface area can significantly be increased and hence the photovoltaic efficiency. Dye-sensitized solar cells (DSSC) based on mesoporous titania has been drawn much attention over the past few years. An attempt in this study is to employ micro-arc oxidation (MAO) process and alkali treatment to develop titania layer with very high specific surface area on pure titanium surface. Specimens were applied an anodic dc voltage at 400–500 V in a phosphate electrolytic solution during MAO process, followed by the alkali treatment in 1.25 M NaOH solution to produce nano-flaky anatase TiO2 on surface, with nano-flakes about 50 nm in dimension thus largely increase specific surface area. Result of photovoltaic efficiency measurement of the assembled DSSC device show that ultimate efficiency (0.23%) can be obtained for the specimen postalkali treated in 1.25 M NaOH solution, which exhibits the highest surface area and thus the enhanced dye-absorbing efficiency.

Copolymerization Mechanisms of Propylene and Norbornadiene Catalyzed by Zirconocene Complexes: A Density Functional Theory Study

Shu-Yuan Yu,Ping Ren,Hui-Min Zheng,Cheng-Gen Zhang 대한화학회 2018 Bulletin of the Korean Chemical Society Vol.39 No.3

Copolymerization mechanisms of norbornadiene (NBD) and propylene, catalyzed by three zirconocene catalysts (namely, rac-Me2Si(2-Me-4-Ph-Ind)2ZrCl2/MAO (catA), rac-Me2Si(Ind)2ZrCl2/MAO (catB), and rac-CH2CH2(Ind)2ZrCl2/MAO(catC)), have been studied, using density functional theory computations. It has been found that the barrier (28.5 kcal mol−1) for the insertion of propylene to the [Zr]A-NBD-PP1 (the NBD insertion product) is significantly higher than those to [Zr]B-NBD-PP1 (22.9 kcal mol−1) and [Zr]C-NBD-PP1 (20.5 kcal mol−1), rationalizing the experimental observation that addition of NBD deactivated catA system but only lowered the catalytic activity of catB and catC systems. However, [Zr]A-NBD-PP1 can react with H2 easily, which displaces NBD−PP1 chain and gives active [Zr]A−H species to continue copolymerization, which is why the introduction of H2 could recover the catalytic activity of catA system.
