BACKGROUND/OBJECTIVES: The association between tea consumption and risk of coronary heart disease (CHD) remains controversial. This study aimed to determine whether tea consumption has an effect on CHD risk in Chinese adults. SUBJECTS/METHODS: In this hospital-based case-control study, 267 cases of CHD and 235 non-CHD controls were enrolled. Blood samples from all cases were examined. Cardiac function indices (left ventricular ejection fraction, left ventricular end-diastolic dimension, lactate dehydrogenase, and creatine kinase of the muscle or brain type), blood lipid index (high-density lipoprotein cholesterol), and blood coagulation function indices (fibrinogen and activated partial thromboplastin time) were recorded. Tea consumption of study participants was assessed by a specifically designed questionnaire. The baseline characteristics of the study populations were recorded, and CHD-related biomarkers were detected. Differences in baseline characteristics of the study participants were examined using t-tests for continuous variables and chi-squared tests for categorical variables. Unconditional logistic regression was used to measure the association between tea and CHD. RESULTS: There were significant differences in cardiac function indices, blood lipid index, and blood coagulation indices between CHD cases and controls (P < 0.05). We found tea consumption reduced CHD risk in female participants (adjusted odds ratio (OR) = 0.484, 95% CI: 0.242-0.968, P = 0.0403). Regarding the type of tea consumed, the risk of CHD was reduced in women who drank partially fermented tea (adjusted OR = 0.210, 95% CI: 0.084-0.522, P = 0.0008). Analytic results for the amount of tea consumed per unit time showed CHD risk was reduced in women who consumed 1-2 cups of tea per day (adjusted OR = 0.291, 95% CI: 0.131-0.643, P = 0.0023). A tea-drinking frequency of > 6 days/week was beneficial for CHD prevention (adjusted OR = 0.183, 95% CI: 0.049-0.679, P = 0.0112). When analyzed according to the duration of tea consumption, the risk of CHD was reduced in participants who had been drinking tea for 10-20 years (adjusted OR = 0.360, 95% CI: 0.137-0.946, P = 0.0382). CONCLUSIONS: Tea consumption is associated with a reduced risk of CHD in female but not male populations in Guangzhou.

Influenza A virus subtype H7N9 has received great attention since the first human case was reported at the beginning of this year. The viral characteristics have been quickly brought into research process. Here, the effect of temperature and live poultry market has been considered on the basis of analysis of existing data. As expected, both temperature and live poultry market has significant impact on the spread of this epidemic. Finally, the effect of government reactions and medical treatment on response was discussed. It indicated that sufficient and rapid reactions did not always lead to a perfect outcome which proved the influence of temperature and live poultry market potentially. Research highlights: The effect of temperature on H7N9 avian influenza is proved by analyzing the latitude and temperature of affected area. The effect of live poultry markets on H7N9 avian influenza is confirmed by analyzing the relationship between the number of live poultry markets in affected area and incidence of H7N9 human infection. The effect of government actions and medical treatment is studied and it turned out the result is not in accordance with actual efforts.

An Chen,Jing Rui Chen,Fei Chi 위기관리 이론과 실천 2017 Journal of Safety and Crisis Management Vol.7 No.1

International cooperation on emergencies is significant to the response of these emergencies. Firstly, the connotation and characteristics of international cooperation on emergencies were analyzed. Secondly, the typical types of emergencies in need of international cooperation, the types of countries involved in international cooperation and the typical types of international cooperation modes on emergencies were analyzed in order to explain the mechanism of international cooperation. Finally, some strategies of international cooperation on emergencies were proposed. The result shows that, in order to have a better international cooperation, international cooperation modes on emergencies should be determined according to the types of emergencies, the situations of countries and organizations involved in it.

Che-Chao Chiang,Min-chi Chang,Po-Tsang Chen,Fu-Ming Chiang 세계문화관광학회 2010 Conference Proceedings Vol.11 No.0

This study examines the information searching of business travelers and their behavior based on the cultural differences. Despite growing academic interest in business travel i n recent years, there has been little investigation of the information search behaviors of business travelers in a cross-culture context. The above themes are rational assumed that information search behaviour are necessary to understand. To address the identified gap s in the literature, the proposed relationships are examined and presented through using chi-square method with a survey sample. The research sample included Japanese, English and Chinese business travellers. A self-administrated questionnaire was distributed to 211 business travelers attending international conventions in Taipei. The research findings reveal that information preferences of business travelers are significantly differed from the three recognized groups in the case of Taiwan. Some significant differences in information search behaviors were recognized amongst the three recognized respondent groups. Marketing implications were also proposed and presented.

Chen-lin Chi,Li-yu Lee,Tseng-tong Kuo 대한병리학회 2015 Journal of Pathology and Translational Medicine Vol.49 No.2

Oncocytic lipoadenoma is a rare tumor, with only 18 cases having been reported since the first in 1998. We encountered a case of oncocytic lipoadenoma presenting as a slowly growing parotid mass in a 71-year-old man. This tumor is characteristically comprised of a mixture of oncocytes and adipocytes. The present case is one of five reported cases of oncocytic lipoadenoma showing sebaceous differentiation. The results of immunohistochemical study with DOG1 antibody supported the origination of this tumor in the striated duct.

Efficient Channel Assignment Scheme Based on Finite Projective Plane Theory

( Chi-chung Chen ),( Ing-jiunn Su ),( Chien-hsing Liao ),( Tai-kuo Woo ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.2

This paper proposes a novel channel assignment scheme that is based on finite projective plane (FPP) theory. The proposed scheme involves using a Markov chain model to allocate N channels to N users through intermixed channel group arrangements, particularly when channel resources are idle because of inefficient use. The intermixed FPP-based channel group arrangements successfully related Markov chain modeling to punch through ratio formulations proposed in this study, ensuring fair resource use among users. The simulation results for the proposed FPP scheme clearly revealed that the defined throughput increased, particularly under light traffic load conditions. Nevertheless, if the proposed scheme is combined with successive interference cancellation techniques, considerably higher throughput is predicted, even under heavy traffic load conditions.

While the Internet continues to integrate with modern lives, the risks of negative outcomes resulting from problematic use (PU) are also increasing. Although psychological well-being and use motivations have been shown to play major roles in Internet PU, understanding the moderating mechanism is critical for advanced knowledge. The present study employed survey data from users of a live video-game streaming service (LVGS) that is an area rarely been studied. Result concluded a positive moderating effect of escapismmotive (EM)on the association between loneliness and the PU of LVGS, while the moderating mechanism between EM and stress was not indicated. A moderating effect of information seeking (IS) on the relationship between stress and the PU of LVGS was found negative, but no mechanism between IS and loneliness was indicated. This study highlights how the interplay of different motivationand pathologies may induce or prevent video-gamerelated addiction.

Witty or wicked? The predictors and impact of agreement with user-generated political satires

Chi-Ying Chen,Shao-Liang Chang 한국인터넷방송통신학회 2016 International Journal of Internet, Broadcasting an Vol.8 No.3

User-generated content (UGC) satirizing the presidential candidates was widespread during the 2016 election in Taiwan. Using an experimental design, this study explored the predictors of viewer agreement to satirical UGC, and its influence on viewer attitudes towards candidates after watching the satirical videos from YouTube. Results showed that participants’ agreement with the satirical UGC was predicted by their political cynicism and political information efficacy, but not by candidate favorability. Watching the UGC satirizing the presidential candidates effected the favorability toward the male candidates but not the female candidate. In addition, the evidence suggested that the frequency of exposure to satirical UGC is related to political information efficacy, but not with political cynicism or candidate favorability.
