Far-infrared stimulation of Neiguan acupoints improves heart rate variability and ameliorate fatigue in hemodialysis patients: A randomized trial
No full text[[abstract]]Background: In 2018, 84 615 patients in Taiwan received hemodialysis, of which about 62% to 97% suffered from fatigue. Fatigue caused by hemodialysis may be mental or physical. However, the detailed mechanism remains unclear. This study aimed to evaluate whether far-infrared stimulation of the Neiguan acupoint (P6) could effectively reduce fatigue and improve heart rate variability (HRV) in hemodialysis patients.
Methods: We conducted a two-arm, randomized trial in a hemodialysis center between March 2015 and March 2016. A total of 73 hemodialysis patients were included and were randomly assigned to an experimental group (n = 37) and a control group (n = 36). The experimental group received far-infrared radiation on Neiguan acupoint during hemodialysis for 12 weeks. The outcomes were fatigue level and HRV.
Results: All patients showed moderate fatigue ( M = 26.00 ± 13.01, range = 0-78) at baseline. Far-infrared stimulation on Neiguan acupoint significantly reduced overall fatigue ( β = 24, p < 0.001) and improved HRV ( β = 74.36, p < 0.001). Compared to the control group, the experiment group had significantly reduced fatigue levels in all aspects such as reduced energy and motivation ( β = -2.97, p < 0.001), reduced physical strength ( β = -1.28, p < 0.01), reduced mental capability ( β = -2.38, p < 0.001), reduction in daily activities ( β = -1.48, p < 0.01), depressed mood and loss of control ( β = -1.21, p < 0.05) as well as increased autonomous nervous system activity ( β = 14.71, p < 0.01) in the third month of stimulation.
Conclusion: Far-infrared stimulation of the Neiguan acupoints effectively reduces fatigue and increases autonomic nervous system activity in hemodialysis patients
新聞情緒指標與台灣加權股價指數之關係
No full text[[abstract]]本研究以媒體文字量化資訊作為新聞情緒（news sentiment）之變數，探討新聞情緒與臺灣加權股價指數報酬率的關係。結果發現正向、負向情緒變數與股價指數報酬率具有統計上的顯著性結果。我們進一步建立投資策略並考量交易成本於做多的績效，發現加入負向情緒變數後之投資策略，其最佳收益率為13.308%、夏普指標為 0.759、期末現值為 197.528（萬），皆比未納入情緒指標 來得高，顯示納入負向新聞情緒於績效指標均表現較好。本研究結果顯示以新聞正、負向內容形成的新聞情緒指標的確能預測股票市場報酬率，且負面情緒 預測能力較正面情緒來得好，與 Tetlock（2007）及 García（2013）的研究結果一致。
This study explores the relationship between positive and negative news sentiment and the returns on the Taiwan weighted stock index by taking media quantitative information as a news sentiment variable. The findings show that these two sentiment variables and the returns on the stock index are statistically significant. Through further establishment of investment strategies and valuing a long position on an option with transactions costs, this study shows that, for the investment strategy with the negative sentiment, the optimal return is 13.308%, the Sharpe ratio is 0.759, and the ending present value is 1,975,280 thousand. They are higher than those strategies with no sentiment variable. This denotes that the performance indicator is better if the negative sentiment variable is included. The results of this study indicate that the negative sentiment is a better prediction than is positive sentiment, which is consistent with the results of Tetlock (2007) and García (2013)

No full text[[abstract]]Lecca et al., in a recent publication in the Int. J. Environ. Res. Public Health had made some mistakes in the statistical analysis and interpretation of the results. Age was not a clear contributing factor in the prolongation of QT interval in the electrocardiogram (ECG), as there were strong confounders in their study. The effects of age were mainly faded out because of the age range of the participants. The use of Pearson's correlation is questionable because of the normality assumptions was not met on the studied variables. They also made some conclusions about the effects of long and night shifts on the QT prolongation that were not appropriate based on their study type. All of these mentioned issues might completely change the validity of the conclusions they made

Reporting a rare case of pleomorphic adenoma of the breast
No full text[[abstract]]Pleomorphic adenoma (PA) is the most common tumor type in the salivary gland. PA is uncommon in the breast tissue. Only 73 cases of PA of the breast have been reported in the world literature. We are reporting the 74th case of PA of the breast. A 61-year-old woman was referred to Shahid Beheshti Hospital Obstetric Clinic with bloody painless discharge from the right nipple. A bean size mass was detected immediately below the right nipple. After an excisional biopsy, the pathologist found proliferation in epithelial and myoepithelial cells that had small and multiple nuclei, myxoid and chondroid stroma. Immunohistochemistry stain was positive for S-100 and patchy for GFAP in tumor cells and for SMA around the tubule-glandular and tumor cell aggregates and suggested PA of the breast. It is essential for the pathologists to consider PA of the breast as a differential diagnosis of a rounded circumscribed mass in the juxta-areolar areas. Careful paraffin sections should be performed to avoid an unnecessary mastectomy
荀子「制天命」說的形成及思想內蘊
No full text[[abstract]]「命」自古以來就是一個來源悠遠且令人感受深刻的概念，荀子既為先秦碩儒之一，對於這個重要的思想命題自然也會有所關注，而「制天命」說即是其命論思想中最具特色的看法。荀子以天生人成的立場強調「命」雖生於天但卻成於人，儘管時命左右了人的際遇窮達，但荀子卻勸君子「博學俟時」，為人成之路找到了一個出口。而透過觀念的追索，我們也發現，除了「俟時」之外其「制天命」思想是循「攝命歸禮」、「以名正命」兩個途徑，以圖恢復「命」在宗教語境中早已失落，卻期望能在人文世界中重建的莊嚴、客觀及權威性。
Since the ancient times, fate has been considered as a distant concept that deeply impresses people. Xun Zi, one of the Confucian apprentices during the Pre-Qin Dynasty, also possessed a nature to focus on significant issues related to Fate. While the ”to Master the Laws of fate” is considered as the most unique perspective in the theory of Fate. Xun Zi emphasized the Fate based on the perspective of natural person born under the sky and hence become a person. Even though the destiny infinitely plays on the man’s fate, Xun Zi suggested that people should keep learning and waiting for the right timing in order to find solutions to solve their problems. Furthermore, through exploration of the concepts, we also found out that aside from waiting for the timing, the God’s Will is also based on the ethics and names that define the fate. The images that recover Fate in the religious environments had faded in the early times. However, people still have the hope to build the world with dignity, objectivity, and authority
Development and psychometric evaluation of the Caregiver Caregiving Self-Efficacy Scale for family members with oral cancer
No full text[[abstract]]Aim: The aim of this study was to develop and initially assess the psychometric properties of the Caregiver Caregiving Self-Efficacy Scale-Oral Cancer (CSES-OC).
Methods: In total, 28 items in the Caregiver Caregiving Self-Efficacy Scale-Oral Cancer were originally employed for a reliability and validity test based on expert suggestions and qualitative findings. The Cronbach's alpha coefficient and test-retest reliability were evaluated with the pilot sample, which included 30 caregivers. The main test, which included 107 caregivers during May 2016 to 2018, was used to execute the exploratory factor analysis (EFA) and concurrent validity.
Results: The results of the main test showed a Cronbach's alpha coefficient of .95 for the revised 18-item total scale after EFA. Four factors (acquiring resources, managing sudden and uncertain patient conditions, managing patient-related nutritional issues and exploring and making decisions on patient care) were classified from EFA of the Caregiver Caregiving Self-Efficacy Scale-Oral Cancer. The r coefficient was .59 (P < .01), which supported the concurrent validity between CSES-OC and General Self-Efficacy Scale.
Conclusion: The study results show appropriate psychometric properties for the Caregiver Caregiving Self-Efficacy Scale-Oral Cancer that was constructed for evaluating caregiver caregiving self-efficacy in caring for family members with oral cancer
