The Relief Effects of Ramelteon on Refractory Chronic Migraine: A Case Report
Yi-Cheng Hou1,Chien-Han Lai 대한정신약물학회 2016 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.14 No.4
The selective melatonin receptor agonism effect of ramelteon is useful for insomnia. Here we wanted to present a refractory chronic migraine case, who had significant improvements in migraine after using ramelteon. The possible mechanism for the ramelteon in the migraine relief might be related to melatonin effects.
Computer vision-based displacement measurement with m-sequence target
Yi-Ding Hu,Qi Xia,Rong-rong Hou,Yong Xia,Jian-yi Yan 국제구조공학회 2021 Smart Structures and Systems, An International Jou Vol.27 No.3
The development of image sensors enables the application of vision-based techniques to the non-contact displacement measurement of large-scale structures. The features of the physical targets are critical to the accuracy, stability and anti-interference of the displacement measurement results. In this study, a novel m-sequence target and the associated circular correlation processing technique are developed for real-time displacement measurement. The properties of the m-sequence as a pseudo-random sequence are introduced. The vision-based displacement calculation method is then derived from the correlation property of the m-sequence. The algorithms and measurement systems are integrated in the LabVIEW environment. To verify the anti-interference performance of the developed system, static and dynamic experimental tests are carried out with various forms of interference, such as partial occlusion, uneven illumination, out of focus and smoke effect. Experimental results indicate that the developed system cannot only accurately measure structural displacement, but also has outstanding antiinterference performance, even if 30% of the target is masked.
Late-onset Quetiapine-related Tardive Dyskinesia Side Effects in a Patient with Psychotic Depression
Yi-Cheng Hou,Chien-Han Lai 대한정신약물학회 2014 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.12 No.2
The atypical antipsychotics were believed to induce less extrapyramidal syndrome, including tardive dyskinesia (TD). Since theintroduction of the quetiapine, it is also reported with less TD side effects. It even can relieve the symptoms of severe TD andreduce the risk of TD. The quetiapine’s low affinity and fast dissociation from postsynaptic dopamine D2 receptors should givethe least risk of producing the symptoms of TD. The quetiapine even can reduce the TD side effects related to clozapine, whichhas the lowest risk for TD. However, since the first case report of TD side effects related to quetiapine published on 1999,the safety of quetiapine in TD aspect has been questioned. Therefore, we want to share this case report, which was writtento describe the severe late-onset TD side effects after long-term use of quetiapine in a patient with psychotic depression. Thepatient had no significant findings after concurrent comprehensive neurological examinations, magnetic resonance imaging ofbrain and electroencephalogram since the onset of TD.

The impacts from the bupropion on the brain structures have seldom been mentioned in the literature. The bupropion is a kind of antidepressant with dual action in the norepinephrine and dopamine receptors. Here we have a case to share about the bupropion-related effects in the brain structure.

<P>The installation of heterojunctions on the surfaces of carbon nanotubes (CNTs) is an effective method for promoting the charge separation processes needed for CNT-based electronics and optoelectronics applications. Conjugated polymers are proven state-of-the-art candidates for modifying the surfaces of CNTs. However, all previous attempts to incorporate conjugated polymers to CNTs resulted in unordered interfaces. Herein we show that well-defined chains of regioregular poly(3-hexylthiophene) (P3HT) were successfully grown from the surfaces of multiwalled CNTs (MWNTs) using surface-initiated Kumada catalyst-transfer polycondensation. The polymerization was found to proceed in a controlled manner as chains of tunable lengths were prepared through variation of the initial monomer-to-initiator ratio. Moreover, it was determined that large-diameter MWNTs afforded highly ordered P3HT aggregates, which exhibited a markedly bathochromically shifted optical absorption due to a high grafting density induced planarization of the polymer chains. Using ultrafast spectroscopy, the heterojunctions formed between the MWNTs and P3HT were shown to effectively overcome the binding energy of excitons, leading to photoinduced electron transfer from P3HT to MWNTs. Finally, when used as prototype devices, the individual MWNT-g-P3HT core-shell structures exhibited excellent photoresponses under a low illumination density.</P>
Multiple-copy-gene integration on chromosome of Escherichia coli for beta-galactosidase production
Shao-Yi Hou,Hsing-Ta Chen,Ming-Shu Lin 한국화학공학회 2008 Korean Journal of Chemical Engineering Vol.25 No.5
Recombinant E. coli strains with 1-3 copies of lacZ genes on their chromosomes were constructed and their β-galactosidase (β-gal) expressions were examined. Serial dilution cultures were used to analyze the long-term genetic stability of the recombinant lacZ genes of the chromosomal or plasmid expression system. The strain with a 3-copy lacZ on the chromosome has a sustainable β-gal expression through 60 hours. However, the β-gal activity of the plasmid expression system lasted less than 36 hours under a no selection condition. Obviously, the genetic stability of the chromosomal expression system demonstrated in this study is better than that of the plasmid expression system under nonselective condition, such as a medium without antibiotics. The results demonstrated that the strains with a multiple-copy-gene on the chromosome are useful for protein production in industrial repeated fed-batch fermentation.
Multilevel LDPC Codes Design for Multimedia Communication CDMA System
Hou, Jia,Yi, Yu,Lee, Moon Ho Hindawi Publishing Corporation 2004 Eurasip Journal on Wireless Communications and Net Vol.2004 No.-
<P>We design multilevel coding (MLC) with a semi-bit interleaved coded modulation (BICM) scheme based on low density parity check (LDPC) codes. Different from the traditional designs, we joined the MLC and BICM together by using the Gray mapping, which is suitable to transmit the data over several equivalent channels with different code rates. To perform well at signal-to-noise ratio (SNR) to be very close to the capacity of the additive white Gaussian noise (AWGN) channel, random regular LDPC code and a simple semialgebra LDPC (SA-LDPC) code are discussed in MLC with parallel independent decoding (PID). The numerical results demonstrate that the proposed scheme could achieve both power and bandwidth efficiency.</P>

Hou, Liyao,Hong, Jong-Yi,Suh, Eui-Ho 한국경영정보학회 2007 한국경영정보학회 학술대회논문집 Vol.2007 No.-
This paper proposes a new model to· evaluate the effectiveness of websites using balanced scorecard (BSC) and weighted formula based methods.fisrt, we Use BSC method to find out the cause-and-effect relationships between the measure and website activities, and our proposed model evaluates website performance from six perspectives: business value, operational excellence, customer value, website interface, management, maintenance, and learning and innovation. Next, we usedformula-based approach to identify what makes website performance low by developing the evaluation formula through investigating website users; finally, case studies of two famous websites are given to show how our method can be used Our evaluation model can not only evaluate website performance but also suggest how to improve performance.
