The Phalaenopsis violacea complex includes two species: P. violacea Witte and Phalaenopsis bellina (Rchb.f.) E. A. Christ. However, three forms of P. violacea have been found in different areas, including Sumatra, the Malay Peninsula, and Mentawai Island. The phylogenetic tree inferred from the internal transcribed spacer (ITS)region of nuclear ribosomal DNA (nrDNA), the trnL intron,and the atpB-rbcL spacer of plastid DNA were used to clarify the phylogenetics and biogeography of the P. violacea complex. Analyses of the trnL intron sequences and of the atpB-rbcL spacer did not allow for apparent discrimination among these three species of the P. violacea complex. Based on the phylogenetic tree inferred from the ITS sequence, P. bellina cannot be separated from populations of P. violacea, with the exception of the population distributed on Mentawai Is., Indonesia. Based on morphological characteristics, P. violacea distributed on Mentawai Is. has a long and roundish rachis and is separate from the other groups of the P. violacea complex described by Christenson (Timber, Portland, OR, 2001). Therefore,the results of this study show a trend that supports the conclusion that the population of the P. violacea complex on Mentawai Is. is a separate species from P. violacea. Based on the biogeography of the P. violacea complex,Mentawai plants of this complex might be descended from those on the Sumatra/Malay Peninsula.

Risk Management of Hazardous Substances in Selection of Green Suppliers
Tsai Chi Kuo,Chih-Hsing Chu 한국정밀공학회 2013 International Journal of Precision Engineering and Vol. No.
In order to satisfy customer requirements to comply with the control of hazardous substances (HS), most suppliers have developed a twofold strategy comprising certified document review and online testing. Nevertheless, many suppliers remain far from complying,collecting, and managing such data efficiently. They encounter significant challenges and risks in screening all the hazardous substance contained in received components as part of the green part approval management (GPAM) process. The present study developed a failure mode and effects analysis (FMEA) for component risk, based on component types. In addition, suppliers’ HS control performance is further evaluated, based on FMEA and X-bar control chart. The results indicate the risk level for each supplier. Finally, the proposed FMEA model is applied to a case study of an electronics supplier.

Background: Diabetic patients are at high risk of developing cancer. Traditional Chinese medicine (TCM) has become increasingly popular as an adjuvant treatment for patients with chronic diseases, and some studies have identified its beneficial effect in diabetic patients with cancer. The purpoes of this study was to outline the potential of TCM to attenuate hospitalization and mortality rates in diabetic patients with carcinoma in situ (CIS). Methods: A total of 6,987 diabetic subjects with CIS under TCM therapy were selected from the National Health Insurance Research Database of Taiwan, along with 38,800 of 1:1 sex-, age-, and index year-matched controls without TCM therapy. Cox proportional hazard analysis was conducted to compare hospitalization and mortality rates during an average of 15 years of follow-up. Results: A total of 3,999/1,393 enrolled-subjects (28.62%/9.97%) had hospitalization/mortality, including 1,777/661 in the TCM group (25.43%/9.46%) and 2,222/732 in the control group (31.80%/10.48%). Cox proportional hazard regression analysis showed a lower rate of hospitalization and mortality for subjects in the TCM group (adjusted HR=0.536; 95% CI=0.367–0.780, P<0.001; adjusted HR=0.783; 95% CI=0.574– 0.974, P = 0.022). Kaplan-Meier analysis showed that the cumulative risk of hospitalization and mortality in the case and control groups was significantly different (log rank, P<0.001 and P = 0.011, respectively). Conclusions: Diabetic patients with CIS under TCM therapy were associated with lower hospitalization and mortality rates compared to those without TCM therapy. Thus, TCM application may reduce the burden of national medical resources.

Application of Data Quality Indicator of Carbon Footprint and Water Footprint
Tsai Chi Kuo,Miao-Ling Huang,Chia Wei Hsu,Chiuhsiang Joe Lin,Chih-Chun Hsieh,Chih-Hsing Chu 한국정밀공학회 2015 International Journal of Precision Engineering and Vol.2 No.1
To mitigate the impact of global warming on the environment, many governments, non-profit organizations, and enterprises have formulated relevant standards to assist enterprises in promoting carbon management, and to encourage the design and popularization of low-carbon products. These standards include: PAS 2050, ISO/TS 14067 and so on. Under these initiatives, enterprises try to disclose the carbon and water footprints of the products based on the life cycle. Some enterprises argue and debate that there exists uncertainty of the footprints calculation since the data collection is not systematically. To solve this problem, in this research, the calculation of carbon footprint and water footprint are evaluated with the data quality indicator (DQI) management system. The collected data is evaluated based on the footprint calculation methods. Also the pedigree matrix is constructed as an aide to solve the data uncertainty that included reliability, completeness, times, geography, and technologies differences. Through the DQI, the carbon footprint and water footprint are not only calculated simultaneously, but also correctly. The results could be the reference for products’ environmental improvement.

Surface Plasmon Resonance in Metallic Nanocylinder Array
Tai Chi Chu,Wei-Chih Liu,Din Ping Tsai 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.47 No.1
Localized surface plasmon resonances of noble-metal nanoparticles lead to high enhancements of local electromagnetic fields near the nanoparticle surface and play a key role in surface-enhanced Raman scattering, surface-enhanced fluorescence, near-field microscopy, and plasmonic devices. Recently, research results have shown that electromagnetic energy can transfer along a metallic nanoparticle chain because of coupled plasmon modes. In this paper, finite-difference time-domain method was used to study the surface plasmon resonances in coupled silver nanocylinder (nanoparticle) arrays and slab-like periodic modulation structures. From the far-field transmittance and reflectance, three different resonance modes were excited for the periodic nanocylinder arrays and only one resonance was excited for the periodic modulation structure. The near-field intensity distributions exhibited highly enhanced fields at the center of the gaps for nanoparticle arrays and at the caves of the periodic modulation structure.

Palliative Care for Adult Patients Undergoing Hemodialysis in Asia: Challenges and Opportunities
Wei-Min Chu,Hung-Bin Tsai,Yu-Chi Chen,Kuan-Yu Hung,Shao-Yi Cheng,Cheng-Pei Lin 한국호스피스완화의료학회 2024 한국호스피스.완화의료학회지 Vol.27 No.1
This article underscores the importance of integrating comprehensive palliative care for noncancer patients who are undergoing hemodialysis, with an emphasis on the aging populations in Asian nations such as Taiwan, Japan, the Republic of Korea, and China. As the global demographic landscape shifts towards an aging society and healthcare continues to advance, a marked increase has been observed in patients undergoing hemodialysis who require palliative care. This necessitates an immediate paradigm shift to incorporate this care, addressing the intricate physical, psychosocial, and spiritual challenges faced by these individuals and their families. Numerous challenges impede the provision of effective palliative care, including difficulties in prognosis, delayed referrals, cultural misconceptions, lack of clinician confidence, and insufficient collaboration among healthcare professionals. The article proposes potential solutions, such as targeted training for clinicians, the use of telemedicine to facilitate shared decision-making, and the introduction of time-limited trials for dialysis to overcome these obstacles. The integration of palliative care into routine renal treatment and the promotion of transparent communication among healthcare professionals represent key strategies to enhance the quality of life and end-of-life care for people on hemodialysis. By embracing innovative strategies and fostering collaboration, healthcare providers can deliver more patient-centered, holistic care that meets the complex needs of seriously ill patients within an aging population undergoing hemodialysis.

Objective Individuals with dementia are at a substantially elevated risk for mortality; however, few studies have examined multimorbidity patterns and determined the inter-relationship between these comorbidities in predicting mortality risk.Methods This is a prospective cohort study. Data from 6,556 patients who were diagnosed with dementia between 1997 and 2012 using the Taiwan National Health Insurance Research Database were analyzed. Latent class analysis was performed using 16 common chronic conditions to identify mortality risk among potentially different latent classes. Logistic regression was performed to determine the adjusted association of the determined latent classes with the 5-year mortality rate.Results With adjustment for age, a three-class model was identified, with 42.7% of participants classified as “low comorbidity class (cluster 1)”, 44.2% as “cardiometabolic multimorbidity class (cluster 2)”, and 13.1% as “FRINGED class (cluster 3, characterized by FRacture, Infection, NasoGastric feeding, and bleEDing over upper gastrointestinal tract).” The incidence of 5-year mortality was 17.6% in cluster 1, 26.7% in cluster 2, and 59.6% in cluster 3. Compared with cluster 1, the odds ratio for mortality was 9.828 (95% confidence interval [CI]=6.708–14.401; p<0.001) in cluster 2 and 1.582 (95% CI=1.281–1.953; p<0.001) in cluster 3.Conclusion Among patients with dementia, the risk for 5-year mortality was highest in the subpopulation characterized by fracture, urinary and pulmonary infection, upper gastrointestinal bleeding, and nasogastric intubation, rather than cancer or cardiometabolic comorbidities. These findings may improve decision-making and advance care planning for patients with dementia.

Objective Schizophrenia has been associated with dysfunction of the hypothalamic-pituitary-adrenal axis. Furthermore, alterations in neurotrophic factors might contribute to the pathogenesis of schizophrenia. We aimed to evaluate the effects of a simulated laughter intervention on the levels of cortisol and BDNF and to determine whether the effects associated with simulated laughter could be sustained after discontinuation of the intervention. Methods In this randomized controlled study, patients with schizophrenia according to DSM-IV clinical criteria were randomly assigned to receive either 8-week-long simulated laughter intervention (n=32) or treatment-as-usual group (control group, n=27). The serum levels of BDNF and cortisol were measured at baseline, week 8, and four weeks after discontinuation (week 12) of the intervention program. Results After an 8-week simulated laughter intervention, the laughter group had significantly higher levels of BDNF; however, four weeks after discontinuation of the intervention, the levels of BDNF significantly dropped. Interestingly, the levels of cortisol did not change significantly at week 8, but they were significantly elevated at week 12. The levels of BDNF and cortisol in the control group did not change significantly between week 0 and week 8. Conclusion These findings suggest that the simulated laughter intervention has an early effect on neurogenesis with a significant delayed effect on stress regulation in subjects with schizophrenia.
