Jenq-Muh Hsu,Wei-Bin Lain,Chih-Chuan Chan,Yi-Ming Huang 보안공학연구지원센터 2008 International Journal of Multimedia and Ubiquitous Vol.3 No.4

Push-to-Talk (PTT) is a half-duplex and one-to-many voice group communication. In past decades, PTT service has been widely adopted in various areas, including practical military, police, security, rescue, and emergency radio communication, etc. In addition, PTT service has also annunciated being an IP Multimedia Subsystem (IMS)-based service defined by Open Mobile Alliance (OMA), which is called Push-to-Talk over Cellular (PoC).Context-aware computing derived from the field of ubiquitous computing as a technique for imbuing application services with an awareness of users’ surroundings and situations for achieving transparent interaction. Thus, a user can obtain some reasonable and proper services among context-aware interactions. In this paper we try combine the features of PoC and context-aware service to implement a context-aware PoC service based on the Open IMS core. The context-aware PoC service can be aware to filter context information and to form an applicable PoC session according to the current contexts of participant PoC users. By the way, our implemented context-aware PoC service can be realizedly used to play an applicable IMS application service in the next generation network (NGN).

Backgrounds/Aims: The protective effect of everolimus (EVR) in hepatocellular carcinoma (HCC) patients who receive liver transplantation in terms of reducing the recurrence has not been sufficiently investigated in clinical trials. In this second stage of our ongoing study, we intend to analyze the effects of EVR as an immunosuppressant, when it is started in the early phase after living donor liver transplantation (LDLT), on HCC recurrence in patients with HCC within the University of California at San Francisco (UCSF) criteria. Methods: From January 2011 to June 2013, a total of 250 patients underwent LDLT for HCC at our institute. The patients with HCC within the UCSF criteria were included in the study and divided in two groups depending upon the postoperative immunosuppression. Group A: HCC patients that received EVR+TAC based immunosuppressive regimen (n=37). Group B: HCC patients that received standard TAC based immunosuppressive regimen without EVR (n=29). The target trough level for EVR was 3 to 5 ng/ml while for TAC it was 8-10 ng/ml. Results: For group A patients, the mean trough level of the EVR was 3.47±1.53 ng/ml (range, 1.5-11.2) with a daily dose of 1.00±0.25 mg/day. For group A and B, the average TAC trough levels were 6.97±3.98 ng/ml (range, 2.50 to 11.28 ng/ml) and 6.93±2.58 (range, 2-16.30), respectively. The 1-year, 3-year and 4-year overall survival achieved for Group A patients was 94.95%, 86.48% and 86.48%, respectively while for Group B patients it was 82.75%,68.96%, and 62.06%, respectively (p=0.0217). Conclusions: EVR use in liver transplant recipients in the early stage after transplantation reduces the HCC recurrence rates in HCC patients within the UCSF criteria.

The objective of the present study was to investigate the accuracy of mastitis diagnostic indicators for different dairy goat breeds. Biweekly milk samples were collected from individual half mammary gland of seven Saanen and seven Alpine dairy goats in the period of 40 to 120 days in milk. With threshold value set at 2.8 and 3.1 for Alpine and Saanen dairy goats, respectively, log (SPC) offered good sensitivity (0.89, 0.93), specificity (0.88, 0.95), positive predictive value (0.75, 0.85) and negative predictive value (0.95, 0.98) as a mastitis diagnostic tool. The correlations of log (SPC) with milk yield, log (SCC), ALP, LDH, $Na^{+}$, $K^{+}$ and EC were significant in Saanen dairy goats (p<0.05), with the highest correlation coefficient (0.653) existing between log (SPC) and log (SCC). The correlations of log (SPC) with milk yield, milk fat, milk protein, log (SCC), $Na^{+}$, $K^{+}$, EC were significant in Alpine dairy goats (p<0.05), with the highest correlation coefficient (0.416) existing between log (SPC) and log (SCC). There were different best-fit regression equations with different multiple diagnostic indicators for Saanen and Alpine dairy goats. In conclusion, different breeds of dairy goats may have to adapt different mastitis diagnostic parameters for a better diagnosis.

Dashdondog Narangarvuu,Chorng-Bin Hsu,Sen-Her Shieh,Fu-Chun Wu,Ping-Shih Yang 한국응용곤충학회 2014 Journal of Asia-Pacific Entomology Vol.17 No.3

In the present study,we assessed the water quality along a stretch of thewatershedwith considerable economicimportance at the Xindian in Taiwan, using macroinvertebrate assemblages, along with environmental variables. The researchwas carried out at the seven sampling sites (abbreviated asXD1–XD7)where human impacts variedin intensity from upstream tributaries to the downstream of the Xindian watershed from December 2010 toDecember 2011. All variables except for the hardness, pH, dissolved oxygen, conductivity, turbidity, phosphate,ammonia, and alkalinity were significantly different (P b 0.05) between the sampling sites. A total of seventyseven taxa belonging to forty five families within eight insect orders, along with three non-insect invertebratetaxa were recorded, with most representative orders being Ephemeroptera and Diptera. Mean values of thedensity, abundance of macroinvertebrates, Shannon index, Simpson index, and Pielou's evenness were muchhigher in the reference sites, XD2, XD3, and XD4 compared with impacted sites, XD5, XD6, and XD7. Most ofthe benthic metrics were greatest in the reference site compared to the impacted site. Only the compositionmeasures, percentages of Chironomidae and Oligochaeta which are more tolerant to pollution were dominantin the impacted site, XD7. As the results of assessment by different benthic metrics, water quality of Xindianwatershed became gradually worse from upstream to downstream. Generally, our results suggest thatmacroinvertebrate assemblages can be used for assessment of water quality.

Chlorophyll-Related Compounds Inhibit Cell Adhesion and Inflammation in Human Aortic Cells

Kuan-Hung Lin,Ching-Yun Hsu,Ya-Ping Huang,Jun-You Lai,Wen-Bin Hsieh,Meng-Yuan Huang,Chi-Ming Yang,Pi-Yu Chao 한국식품영양과학회 2013 Journal of medicinal food Vol.16 No.10

The objectives of this study were to investigate the effects of chlorophyll-related compounds (CRCs) and chlorophyll (Chl) a + b on inflammation in human aortic endothelial cells. Adhesion molecule expression and interleukin (IL)-8, nuclear factor (NF)-jB p65 protein, and NF-jB and activator protein (AP)-1 DNA binding were assessed. The effects of CRCs on inflammatory signaling pathways of signal transducers and activators of transcription 3 (STAT3) and mothers against decapentaplegic homolog 4, respectively induced by IL-6 and transforming growth factor (TGF)-b, in human aortic smooth muscle cells cultured in vitro were also investigated. HAECs were pretreated with 10 lM of CRCs, Chl a + b, and aspirin (Asp) for 18 h followed by tumor necrosis factor (TNF)-a (2 ng/mL) for 6 h, and U937 cell adhesion was determined. TNF-a–induced monocyte-endothelial cell adhesion was significantly inhibited by CRCs. Moreover, CRCs and Chl a + b significantly attenuated vascular cell adhesion molecule-1, intercellular adhesion molecule-1, and IL-8 expressions. Treatments also significantly decreased in NF-jB expression, DNA binding, and AP-1 DNA binding by CRCs and Asp. Thus, CRCs exert anti-inflammatory effects through modulation of NF-jB and AP-1 signaling. Ten micromoles of CRCs and Asp upregulated the expression of mothers against decapentaplegic homolog 4 (Drosophila) (SMAD4) in the TGF-b receptor signaling pathway, and SMAD3/4 transcription activity was also increased. Ten micromoles of CRCs were able to potently inhibit STAT3-binding activity by repressing IL-6–induced STAT3 expression. Our results provide a potential mechanism that explains the anti-inflammatory activities of these CRCs.

Undergraduates' intentions to take examinations for professional certification: examinations of four competing models

Pi-Yueh Cheng,Ping-Kun Hsu,Wen-Bin Chiou 서울대학교 교육연구소 2012 Asia Pacific Education Review Vol.13 No.4

Previous research on professional certification has primarily focused on graduate certificates in intensive care nursing, writing certificates for practitioners, maintenance of certification in radiation oncology, and the certification of teachers and surgeons. Research on certification in the domain of business and management from an attitudinal-behavioral approach has been lacking. Social psychological theories provide potentially useful tools for explaining how attitudes, intentions, and behaviors are changed. The current study compared four intention-based models-the theory of planned behavior, the theory of self-regulation (TSR), the revised TSR (in which desire is a partial mediator), and the other revised TSR (in which desire is a full mediator)-in terms of their ability to predict the intentions of business and management students to obtain certification in their fields. Participants were drawn from the southern, middle, and northern areas of Taiwan. A structural equation model applied to a sample of 273 undergraduates demonstrated that attitudes, subjective norms, perceived behavioral controls, desires, intentions, and behaviors were associated with certification in business and management domains. The explanatory power of the revised TSR in which desire was a full mediator was superior to that of the competing models. Implications and future directions are discussed.

Strain measurement of polymer materials by digital image correlation combined with finite-element analysis

Shun-Fa Hwang,Min-Chien Shen,Bin-Bin Hsu 대한기계학회 2015 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.29 No.10

Digital image correlation (DIC) can provide deformation information of a specimen by processing its two digital images captured beforeand after the deformation. In this study, a DIC method based on a modified coarse–fine iterative method is combined with finiteelementanalysis to obtain the strain and displacement data. This method is first verified with the use of an aluminum specimen underuniaxial testing. For polymer materials, polypropylene specimens with and without short glass fibers and polydimethylesiloxane specimenswith and without dyes are tested. Results indicate that the present method can capture the strains of these specimens even underhigh elongation and without artificial speckle pattern on their surfaces. Thus, the mechanical behavior of polymer materials can be characterizedand the effects of additional ingredients added to the materials can be assessed through the developed DIC method.
