Yen, Ching-Ho,Chang, Chia-Hao,Aslam, Muhammad,Jun, Chi-Hyuck Informa UK (TaylorFrancis) 2018 Communications in Statistics Vol.47 No.6

<P>In this research, multiple dependent state and repetitive group sampling are used to design a variable sampling plan based on one-sided process capability indices, which consider the quality of the current lot as well as the quality of the preceding lots. The sample size and critical values of the proposed plan are determined by minimizing the average sample number while satisfying the producer's risk and consumer's risk at corresponding quality levels. In addition, comparisons are made with the existing sampling plans [Pearn and Wu (2006a), Yen etal. (2015)] in terms of average sample number and operating characteristic curve. Finally, an example is provided to illustrate the proposed plan.</P>

An Internet Based Embedded Network Monitoring System for Renewable Energy Systems

Po-Yen Chen,Se-Kang Ho,Wei-Jen Lee,Chia-Chi Chu,Ching-Tsa Pan 전력전자학회 2007 ICPE(ISPE)논문집 Vol.- No.-

In this paper, an internet based embedded network monitoring system is proposed for renewable energy systems. By using a low cost network communication module (RCM 3700) as a web server, one can achieve better network security, lower power consumption, compact size, and easier to use as compared with a PC based one. Also, Java language is chosen for designing a dynamic webpage to graphically display various real time waveforms of the controlled system for multi-user at the same time. As an illustrative example, a small scale wind power generation system equipped with an EZDSP 2812 controller is adopted for demonstration. In addition, an FPGA EC10 is implemented as a bidirectional communication interface for coordinating the asynchronous data transmission modes. Experimental results from the constructed prototype verify that the proposed monitoring system can indeed achieve the desired function.

Effects of Specific Power-Loss on the Characteristics of Temperature in Magnetic Nanoparticles Subjected to External Alternating Magnetic Fields

Qiao Dongkai,Ho Chia-Chieh,Ho Ching-Yen,Chen Bor-Chyuan,Wen Mao-Yu 한국물리학회 2020 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.77 No.10

The variation of the specific power-loss with the anisotropy constant takes an approximately exponential form when magnetic nanoparticles (MNPs) are subjected to external alternating magnetic fields, and the distribution of the specific power-loss along the anisotropy constant shifts with temperature. Furthermore, the rate of increase in the temperature of MNPs used for hyperthermia depends significantly on the specific power-loss. Hence, the temperature characteristics of hyperthermia are affected by the specific power-loss. In this work, we develop a thermal model to analyze the effect of specific power-loss on temperature characteristics in MNPs uses for tumor hyperthermia. The results predicted by using the thermal model in this study are consistent with the available experimental data. The rate of increase of the temperature evidently varies at different temperatures due to different specific power-losses. An abrupt temperature rise occurs at the highest value in the distribution of the specific power-loss versus anisotropy constant. On the other hand, a slow temperature rise occurs when the intersection between the anisotropy constant of the MNPs and the specific power-loss distribution along the anisotropy constant at a some certain temperature corresponds with low specific power-loss.

Creatine Kinase (CK)-MB-to-Total-CK Ratio: a Laboratory Indicator for Primary Cancer Screening

Chang, Chih-Chun,Liou, Ching-Biau,Su, Ming-Jang,Lee, Yi-Chen,Liang, Chai-Ting,Ho, Jung-Li,Tsai, Huang-Wen,Yen, Tzung-Hai,Chu, Fang-Yeh Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.15

Background: For the determination of creatine kinase (CK)-MB, the immunoinhibition method is utilized most commonly. However, the estimated CK-MB activity may be influenced by the presence of CK isoenzymes in some conditions like cancer. Thus, a CK-MB-to-total-CK ratio more than 1.0 could be found in such a situation. The study aimed to explore the relationship of cancer to high CK-MB-to-total-CK ratio. Materials and Methods: From January 2011 to December 2014, laboratory data on all CK-MB and total CK test requests were extracted at Far Eastern Memorial Hospital (88,415 requests). Patients with a CK-MB-to-total-CK ratio more than 1.0 were registered in this study. Clinical data including tumor location, tumor TNM stage and metastatic status were also collected. Results: A total of 846 patients were identified with a CK-MB-to-total-CK ratio more than 1.0. Of these, 339 (40.1%) were diagnosed with malignancies. The mean CK-MB-to-total-CK ratio was significantly higher in malignancy than in non-malignancy ($1.35{\pm}0.28$ vs $1.25{\pm}0.23$, p<0.001) groups. The most frequent malignancy with a CK-MB-to-total-CK ratio more than 1.0 was colorectal cancer ($1.42{\pm}0.28$, 16.5%, n=56), followed by lung cancer ($1.38{\pm}0.24$, 15.9%, n=54) and hepatocellular carcinoma (14.5%, n=49). Higher CK-MB-to-total-CK ratios in hematological malignancies ($1.44{\pm}0.41$)were also noted. Additionally, the CK-MB-to-total-CK ratio was markedly higher in advanced stage malignancy than in early stage ($1.37{\pm}0.26$ vs. $1.29{\pm}0.31$, p=0.014) and significantly higher in liver metastasis than in non-liver metastasis ($1.48{\pm}0.30$ vs. $1.30{\pm}0.21$, p<0.001). Conclusions: The CK-MB-to-total-CK ratio is an easily available indicator and could be clinically utilized as a primary screening tool for cancer. Higher ratio of CK-MB-to-total-CK was specifically associated with certain malignancies, like colorectal cancer, lung cancer and hepatocellular carcinoma, as well as some cancer-associated status factors such as advanced stage and liver metastasis.

Aim(s): Clinical nurses are facing patients’ biopsychosocial and spiritual problems at diverse clinical settings, but they are lack of knowledge, skills, and confidence on providing spiritual care. However, no studies adopted simulated educational program and objective structure clinical examination (OSCE) to educate nurses and to assess the outcomes. Therefore, this study was to validate the effect of a scenario-based spiritual care course on spiritual care competence in clinical nurses. Methods: This non-equivalent quasi-experimental study with a pre-test and two post-tests (end of the intervention and three months later) was conducted between August 2019 and February 2021 (11 sessions). The recruitment posters with a QR code were distributed to different units at three branches of a large medical institute for recruiting clinical nurses, who provided direct patient care. The attendees of one-day scenario-based spiritual care course are the experimental group (n=53) and the control group (n=85) was matched with the experimental group (1:1-3 ratio) by similar units, ages, working experience, and clinical ladder. Instruments include basic information, self-evaluated and head nurses evaluated spiritual care competence scale (SCCS), spiritual perspective scale (SPS), and spiritual care perspective scale-revised (SCPSR) for both groups and reflective log, course satisfaction scale, OSCE checklist, and standardized patient feedback scale for the experimental group. The data were analyzed using descriptive statistics, repeated measures ANOVA, linear regression, and paired t test. Results: After controlling for pre-test scores and interest in attending spirituality/spiritual care, the experimental group showed significant higher SPS (p=0.012) and self-evaluated SCCS (p=0.002) and lower SCPSR (p=0.015) than the control group at the 2nd post-test. Repeated measure ANOVA also showed significant within-subject effects across three time points of the experimental group on SPS (p<0.001), SCPSR (p<0.001), and self-evaluated SCCS (p<0.001), but paired t test showed non-significant differences on SPS, SCPSR, and self-evaluated SCCS between pre-test and post-test with an exception of head nurse evaluated SCCS (p=0.035). The mean overall course satisfaction of the experimental group was 4.34±0.62. The mean global performance of OSCE was 3.40±0.91 and the majority of experimental group was pass (43.4%) and good (35.8%). 64.5% and 26.1% of standardized patients were partial and strongly agreed with examinees’ performance in spiritual care assessment respectively. Conclusions: The scenario-based spiritual care course is effectively to enhance clinical nurses’ spiritual care competence. It may cultivate clinical preceptors with better spiritual care pedagogy through simulation and OSCE for bedside teaching of nurse post-graduate year.
