PLOS ONE , 2012, DOI: 10.1371/journal.pone.0007820
Abstract: Tumor suppressor WOX1 (also named WWOX or FOR) is known to participate in neuronal apoptosis in vivo. Here, we investigated the functional role of WOX1 and transcription factors in the delayed loss of axotomized neurons in dorsal root ganglia (DRG) in rats.
Efficacy of Topical Microfibrillar Collagen Mixed with Steroid Hormone and Morphine for Postoperative Pain Control during Lumbar Laminectomy: A Preliminary Report
Tzu-Yung Chen
Chang Gung Medical Journal , 2002,
Abstract: Background: Current inpatient management of postoperative pain in lumbar surgeryincludes the use of intramuscular opioid analgesics, nonsteroidal anti-inflammatorydrugs, or patient-controlled analgesia; however, all types of medicationsare associated with side effects that can limit their usefulness in theinpatient setting.Methods: In a well-conducted non-randomized prospective trial, 80 consecutivepatients who underwent elective multilevel lumbar laminectomy surgerywere identified. Two types of trials with different doses of steroids wereused. Patients' preoperative medical records, pain scores, narcotics consumption,costs for the regimen, hospital stay, unwanted complications, andwalking ability were evaluated postoperatively.Results: Pain in patients after lumbar surgery can be dramatically controlled postoperatively.Seventy-eight patients (97.5%) were able to walk without support onthe first postoperative day. Major side effects were found in 5 patients(6.2%).Conclusions: This experience indicates that pain-control agents with epidural sustainedreleasedpreparation seem to be beneficial in early mobilization, are costeffective, and require lower analgesic consumption by patients. Similar paincontrol can be obtained with lower doses of methylprednisolone. In spite ofits clinical attractiveness, improvements in the side effects of complicationsfrom epidural morphine and the combination of steroids and microfibrillarcollagen have yet to be realized.
Successful Treatment of Colorectal Anastomotic Stricture by Using Sphincterotomes
Tzu-An Chen
Frontiers in Surgery , 2014, DOI: 10.3389/fsurg.2014.00022
Abstract: Colorectal or colocolic anastomotic stricture is a common complication after colorectal surgery. Traditionally, endoscopic balloon dilation technique was used for those patients with symptomatic stricture. The use of electroincision (radial incisions of the scar) along with pneumatic balloon dilation was reported with good result in literature. We present a novel method for relieving colorectal anastomotic stricture by using sphincterotomes, which is indicated for use in the cannulation of the biliary ducts and the transendoscopic sphincterotomy of the papilla of Vater and the sphincter of Oddi. The use of sphincterotomes in upper GI tract anastomotic stricture was reported before, but the experience in managing lower GI tract was pending. Based on our preliminary report, sphincterotomes can be an effective and safe treatment option for colorectal anastomotic stricture.
Lightening Global Types
Tzu-chun Chen
Computer Science , 2014, DOI: 10.4204/EPTCS.155.6
Abstract: Global session types prevent participants from waiting for never coming messages. Some interactions take place just for the purpose of informing receivers that some message will never arrive or the session is terminated. By decomposing a big global type into several light global types, one can avoid such kind of redundant interactions. Lightening global types gives us cleaner global types, which keep all necessary communications. This work proposes a framework which allows to easily decompose global types into light global types, preserving the interaction sequences of the original ones but for redundant interactions.

Chang-Tzu Chiang, Wan-Chen Yu
iBusiness (IB) , 2010, DOI: 10.4236/ib.2010.24045
Abstract: The rapidly changing social situation in the latter part of the 20th century, such as revolutionary movement for women’s equal rights, significantly affects the women consumer behaviors as well as improves their social status. The awakening of female consumer’s consciousness during the recent years leads to alteration of consumer behavior, and influences the women’s usual conception for pursuing fashion and cosmetics application, in fact, the makeup practice has already been regarded as a social politeness and necessary requirement for interpersonal activities. By employing the Means-End Chain theory, this study intends to explore the attribute, result, and value attached importance by female consumer towards cosmetic products, in order to realize consumer’s cosmetics application process. The female consumers in Hsinchu are taken as research targets for this study to conduct variable analysis of their lifestyle and demographic statistics. Totally 550 questionnaires were released and 390 copies are effective among the retrieved ones. Methods as factor analysis and ANOVA are applied for examining various study hypotheses. Moreover, the implementation of Means-End Chain theory allows cosmetics industry to better understand the signification of product attribute valued by consumers so as to anticipate the details of consumer result and value recognition experienced by consumers.
Moral Norm and the Two-Component Theory of Planned Behavior Model in Predicting Knowledge Sharing Intention: A Role of Mediator Desire  [PDF]
Chi-Cheng Huang, Tzu-Hui Chen
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.613165
Abstract: Knowledge sharing is becoming an increasingly popular area and has been extensively discussed in knowledge management literature. The theory of planned behavior (TPB) is a leading theoretical model of cognitive determinants of behavior that has been shown to predict knowledge sharing. Although the TPB has been used in predicting knowledge sharing, integrating additional variables or theories may heighten the predictive ability of the TPB. This study proposes an integrated model that considers desire and moral norm in a two-component TPB model for predicting knowledge sharing intention. Our models are assessed by using data from a sample of 220 participants in one of the largest credit cooperatives in Taiwan and analyzed using the partial least squares (PLS) method. The results of this study indicate that 1) moral norm is an important variable in predicting desire toward knowledge sharing; 2) desire fully mediates the relationship between cognitive attitude and intention; and 3) desire partially mediates the relationships between affective attitude, self-efficacy, moral norm and intention. This study also discusses the implications of knowledge sharing intention.

Abstract: Saccharomycopsis ferment filtrate (SFF), mainly used in skin care products, has been reported to inhibit inflammatory nitric oxide production and prevent epidermal damage. However, the effects of SFF on epidermal keratinocytes have not yet been explored. We investigated the effects of SFF on skin barrier function using human primary epidermal keratinocytes. Cell viability was determined by MTT assay. The mRNA and protein expression levels of tight junction proteins (claudin-1, -3, -4, occludin, ZO-1) were analyzed by RT-PCR and Western blotting, respectively. The effect of SFF on the barrier formation of epidermal keratinocytes was measured by transepithelial electrical resistance (TER). Rescue of cell death from H2O2 treatment was evaluated by annexin V staining. SFF, at concentrations that did not cause significant change of cell viability, induced dose-dependent cell-cell adhesion and formation of an organized monolayer structure. Pretreatment of keratinocytes with EGTA, a Ca2+ chelator, did not inhibit the cell-cell adhesion of keratinocytes by SFF, indicating a Ca2+-independent mechanism. The mRNA and protein levels of claudin-1 in keratinocytes were up-regulated by SFF treatment in a dose-dependent manner. The expressions of other tight junctions (TJs) including claudin-3 & 4, occludin and ZO-1 were also similarly increased in SFF-treated epidermal keratinocytes. The promoting effect of SFF on the barrier function of epidermal keratinocytes was further confirmed by the increased TER value in SFF-treated epidermal keratinocytes. Annexin V staining confirmed that SFF markedly decreased the number of dead cells resulted from H2O2 injury. Taken together, our results provided the first evidence that SFF enhanced keratinocytes barrier function by increasing the expression of TJs and TER.
Assessing Measurement Noise Effect in Run-to-Run Process Control: Extends EWMA Controller by Kalman Filter
Tzu-Wei Kuo, An-Chen Lee
International Journal of Automation and Smart Technology , 2011, DOI: 10.5875/ausmt.v1i1.71
Abstract: Recently, the Exponentially Weighted Moving Average (EWMA) controller has become a popular control method in Run-to-Run (RtR) process control, but the issue of measurement noise from metrology tools has not been addressed in RtR EWMA controllers yet. This paper utilizes a Kalman Filter (KF) controller to deal with measurement noise in RtR process control and investigates the output properties for steady-state mean and variance, and for closed-loop stability. Five disturbance models modeling semiconductor process disturbances are investigated. These disturbance models consist of Deterministic Trend (DT), Random Walk with Drift (RWD), Integrated Moving Average process (IMA(1,1)), AutoRegressive Moving Average (ARMA(1,1)), and Autoregressive Integrated Moving Average (ARIMA(1,1,1)). Analytical results show that a KF controller can be considered as an extended version of a RtR EWMA controller. In particular, the EWMA controller is a special case of KF in a filtering form without the capability of measuring noise. Simulation results also show that the KF has a better ability to deal with measurement noise than the EWMA controller.

Engineering (ENG) , 2016, DOI: 10.4236/eng.2016.87044
Abstract: The construction of fully closed check dam (CD) is a conventional flood prevention mechanism implemented on rivers. Fully closed CDs trap large amounts of sediments in rivers to stabilize the river slopes and control erosion. However, fully closed CDs cannot selectively trap sediment and may easily overflow, causing them to losing their ability to mediate and hold sediments. Previous studies proposed the concept of “breathable CDs”. The researcher introduced metal slit dam (SD) that could be assembled and disassembled quickly and conveniently. Once a CD reaches maximum capacity, operators must ensure that the water channels of the dam are free from blockage. Moreover, they must inspect the internal accumulation conditions of the dam periodically or immediately following heavy typhoon rains. When necessary, either the sediment buildup in the upriver blockage must be cleared, or the transverse structure of the dam must be removed to allow fine particles to be discharged along with a moderate amount of water. These actions can free up the sediment-storing capacity of the dam for the next heavy typhoon rains. In addition, operators should also inspect the damages inflicted on the dam, such as erosion, wear and tear, and deformation conditions. Damaged components should be disassembled and repaired if possible, or recycled and reused. The present study performed channel tests to simulate closed CDs, SDs, steel pipe dam (SPDs), and steel pipe plus slit dam (SPSDs) for 50-year and 100-year frequency floods. Results were then analyzed to determine the sediment trapping (ST) effects of various CDs, the effects of “adjustable CDs”, and the changes of moderated riverbeds.

Advances in Entomology (AE) , 2017, DOI: 10.4236/ae.2017.51004
Abstract: This article examined 20 species of grasshoppers, belonging to six families, in Guandaushi forest ecosystem by studying the food plants and the morphology of their mandible, among which, three species are still under further identification. Based on SEM observations, the mandibles of them could be grouped into three types corresponding to their food plant: type 1 forb-feeding, the mandible with inc is or surface consists of sharp dents, and the molar area is a deep, central concavity surrounded by short ridges; type 2 grass-feeding, the incisor surface is somewhat smooth without dents, and the molar surface has long parallel grinding ridges without central concavity; type 3 obligate-feeding, the incisor is blunt, and the molar consists of ridges with a central concavity shorter than type 1. Among the 20 species of grasshoppers in Guadaushi forest ecosystem, the ones belonging to type 1 are Traulia ornata ornata Shiraki, 1910, Xenocatantops humilis (Seville, 1839) and Coptacra sp. 3 of Catantopidae; Atractomorpha sinensis I. Bolivar, 1905 of Pygomorphidae and Erianthella formosana (Shiraki, 1910) of Eumastacidae. The species belonging to type 2 are Oxya podisma Karny, 1915, Oxyrrhepes obtuse (De Haan, 1842) of Catantopidae; Phlaeoba albonema Zheng, 1981, Phlaeoba formosana Shiraki, 1910, and Phlaeoba sinensis I. Bol., 1914of Acridae; Formosacris koshunensis (Shiraki, 1910) and Dnopherula svenhedini (Sjöstedt, 1933) of Arcypteridae and Pternoscirta sauteri (Karny, 1915), Heteropternis respondens (Walker, 1859) and Trilophidia annulata (Thunberg, 1815) of Oeipodidae.
