( Wei-ting Cho ),( Chin-feng Lai ),( Yueh-min Huang ),( Wei-tsong Lee ),( Sing-wei Huang ) 한국인터넷정보학회 2011 KSII Transactions on Internet and Information Syst Vol.5 No.7
Due to the variety of household electric devices and different power consumption habits of consumers at present, general home energy management (HEM) systems suffer from the lack of dynamic identification of various household appliances and a unidirectional information display. This study presented a set of intelligent interconnection network systems for electric appliances, which can measure the power consumption of household appliances through a current sensing device based on OSGi platform. The system establishes the characteristics and categories of related electric appliances, and searches the corresponding cluster data and eliminates noise for recognition functionality and error detection mechanism of electric appliances by applying the clustering algorithm. The system also integrates household appliance control network services so as to control them according to users` power consumption plans or through mobile devices, thus realizing a bidirectional monitoring service. When the system detects an abnormal operating state, it can automatically shut off electric appliances to avoid accidents. In practical tests, the system reached a recognition rate of 95%, and could successfully control general household appliances through the ZigBee network.

Spontaneous intracerebral hemorrhage (sICH) has a high mortality rate. Research has demonstrated that sICH occurrence is related to weather conditions; therefore, this study used the decision tree method to explore the impact of climatic risk factors on sICH at different ages. The Taiwan National Health Insurance Research Database (NHIRD) and other open-access data were used in this study. The inclusion criterion was a first-attack sICH. The decision tree algorithm and random forest were implemented in R programming language. We defined a high risk of sICH as more than the average number of cases daily, and the younger, middle-aged and older groups were calculated as having 0.77, 2.26 and 2.60 cases per day, respectively. In total, 22,684 sICH cases were included in this study; 3,102 patients were younger (<44 years, younger group), 9,089 were middle-aged (45-64 years, middle group), and 10,457 were older (>65 years, older group). The risk of sICH in the younger group was not correlated with temperature, wind speed or humidity. The middle group had two decision nodes: a higher risk if the maximum temperature was >$19^{\circ}C$ (probability = 63.7%), and if the maximum temperature was <$19^{\circ}C$ in addition to a wind speed <2.788 (m/s) (probability = 60.9%). The older group had a higher risk if the average temperature was >$23.933^{\circ}C$ (probability = 60.7%). This study demonstrated that the sICH incidence in the younger patients was not significantly correlated with weather factors; that in the middle-aged sICH patients was highly-correlated with the apparent temperature; and that in the older sICH patients was highly-correlated with the mean ambient temperature. "Warm" cold ambient temperatures resulted in a higher risk of sICH, especially in the older patients.

Use of Lactobacillus Brevis LUC247 to Enrich Quinoa Sourdough with Γ-Aminobutyric Acid
( Ting Wei Liu ),( Chao Feng Yu ),( Syue Fong Lai ),( Ying Chen Lu ) 한국농업기계학회 2018 한국농업기계학회 학술발표논문집 Vol.23 No.1
γ-Aminobutyric acid is a neurotransmitter inhibitor with sedation, anti-depression, hypotensive and other physiological functions. This study aimed at investigating the effect of addition various amount of quinoa (Chenopodium quinoa) flours to sourdough in γ-aminobutyric acid production. Type I sourdough containing quinoa flours of different content (0%, 15%, 30%, 45%) were prepared in laboratory. Lactobacillus brevis LUC247 was used to ferment quinoa sourdough during different fermentation time (0, 2, 4, 6, 8, 12, 24, 36, 48 hours). Compared to control dough, without quinoa, the amount of GABA was representing about 3-fold increase, Cell count of Lactobacillus brevis LUC247 in quinoa sourdough fermented for 12 hours was the highest (1E+9 CFU/g). The higher the inoculated cell counts, the faster the pH decreased and total titratable acidity and organic acid (lactic acid and acetic acid) amounts increased in quinoa sourdough. The results indicated the potential of quinoa flour through sourdough fermentation by Lactobacillus brevis LUC247 to enrich γ-aminobutyric acid.

Purpose Patients with advanced biliary tract cancer (BTC) have a poor survival. We aim to evaluate the efficacy and safety of nab-paclitaxel plus gemcitabine and cisplatin regimen in Chinese advanced BTC patients.Materials and Methods Eligible patients with locally advanced or metastatic BTC administrated intravenous 100 mg/m<sup>2</sup> nab-paclitaxel, 800 mg/m<sup>2</sup> gemcitabine, and 25 mg/m<sup>2</sup> cisplatin every 3 weeks. The primary endpoint was progression-free survival (PFS). The secondary endpoints included overall survival (OS) and adverse events, while exploratory endpoint was the association of biomarkers with efficacy.Results After the median follow-up of 25.0 months, the median PFS and OS of 34 enrolled patients were 7.1 months (95% confidence interval [CI], 5.4 to 13.7) and 16.4 months (95% CI, 10.9 to 23.6), respectively. The most common treatment-related adverse events at ≥ 3 grade were neutropenia (26.5%) and leukopenia (26.5%). Survival analyses demonstrated that carcinoembryonic antigen (CEA) levels could monitor patients’ survival outcomes. A significant increase in the number of infiltrating CD4+ cells (p=0.008) and a decrease in programmed death-1–positive (PD-1+) cells (p=0.032) were observed in the response patients.Conclusion In advanced BTC patients, nab-paclitaxel plus gemcitabine and cisplatin regimen showed therapeutic potential. Potential prognostic factors of CEA levels, number of CD4+ cells and PD-1+ cells may help us maximize the efficacy benefit.
A Simple Timeout Algorithm for Point-to-Multipoint ABR Service
Lai, Wei-Kuang,Chen, Chien-Ting,Li, Chilin The Korea Institute of Information and Commucation 2004 Journal of communications and networks Vol.6 No.1
The ABR point-to-multipoint connection is now playing a more important role than before. Many consolidation algorithms have been proposed to solve the consolidation noise problem and the slow transient response problem. But few timeout algorithms are proposed to handle the non-responsive branches for the multicast connections. Chen’s algorithm needs exchanging control messages between switches [9]. Besides, it may mistake a responsive branch as a non-responsive branch because of fast changes in source rates, which causes wrong information in BRM cells and may lead to network congestion and data losses in the responsive branch. We propose a simple timeout algorithm which can handle the non-responsive branches without exchanging message between switches. The timeout value for each switch is computed locally. Simulation results show that the proposed timeout algorithm can efficiently handle the non-responsive branches and utilize the available bandwidth within a small period of time. In addition, our algorithm could handle the situation when the source rates change quickly.
