The Today Tendency of Sentiment Classification

Sentiment classification has already been studied for many years because it has had many crucial contributions to many different fields in everyday life, such as in political activities, commodity production, and commercial activities. There have been many kinds of the sentiment analysis such as machine learning approaches, lexicon-based approaches, etc., for many years. The today tendency of the sentiment classification is as follows: (1) Processing many big data sets with shortening execution times (2) Having a high accuracy (3) Integrating flexibly and easily into many small machines or many different approaches. We will present each category in more details

TÌNH HÌNH BỆNH TRÊN CÁ BÓP (Rachycentron canadum) VÀ CÁ MÚ (Epinephelus sp.) NUÔI LỒNG BIỂN Ở QUẦN ĐẢO NAM DU, HUYỆN KIÊN HẢI, TỈNH KIÊN GIANG

The study was conducted to investigate the current status of marine fish diseases in cobia and grouper cage culture in Nam Du islands, Kien Hai district, Kien Giang province. Cobia cage culture (n = 25) and grouper cage culture farmers (n = 25) were directly interviewed from October to December 2013. The results showed that the diseases on cobia and grouper yearly occurred but mainly in two periods of April - May and July to September. The main diseases were reported during cobia culture including ulceration (72%), hemorrhage (64%) and exophthalmia (100%). Parasitic infection was also reported. Chemical was not commonly used during culture period, but antibiotics were used to treat the bacterial diseases. The most common antibiotics were tetracycline, streptomycin, rifamycin and oxytetracycline. Farmers reported grouper diseases comprising ulceration (50%), hemorrhage (38.4%), exophthalmia (11.5%) and parasite infections (23.1%). During husbandry practices, some chemicals (Potassium permanganate, Iodine, Copper sulfate) and antibiotics (rifamycin, oxytetracycline, tetracycline, ampicillin, nutroplex) were limitedly used.Tình hình bệnh trên cá bóp và cá mú nuôi lồng biển ở quần đảo Nam Du, huyện Kiên Hải, tỉnh Kiên Giang được khảo sát thông qua phỏng vấn trực tiếp 25 hộ nuôi cá bóp và 25 hộ nuôi cá mú từ tháng 10-12/2013. Kết quả khảo sát cho thấy, bệnh trên cá bóp và cá mú xuất hiện quanh năm nhưng tập trung chủ yếu vào tháng 4-5 và tháng 7-9. Các bệnh xuất hiện trên cá bóp gồm bệnh lở loét chiếm 72%, xuất huyết 64%, mù mắt 100% và trong quá trình nuôi không có sử dụng hóa chất, chỉ sử dụng các loại kháng sinh dùng để trị bệnh như tetracycline, streptomycin, rifamycin, oxytetracycline. Các bệnh xuất hiện trên cá mú gồm bệnh lở loét chiếm 50%, xuất huyết 38,4%, mù mắt 11,5% và 23,1% bệnh do ký sinh trùng và trong quá trình nuôi cá mú các loại hóa chất (thuốc tím, iodine, sunfat đồng) và các loại kháng sinh (rifamycin, oxytetracycline, tetracycline, ampicillin, nutroplex) rất ít được sử dụng. Hầu hết người nuôi còn thiếu kiến thức về chẩn đoán và phòng, trị bệnh trên cá nuôi

Lower and upper bound intercept probability analysis in amplifier-and-forward time switching relaying half-duplex with impact the eavesdropper

In this paper, we proposed and investigated the amplifier-and-forward (AF) time switching relaying half-duplex with impact the eavesdropper. In this system model, the source (S) and the destination (D) communicate with each other via a helping of the relay (R) in the presence of the eavesdropper (E). The R harvests energy from the S and uses this energy for information transferring to the D. For deriving the system performance, the lower and upper bound system intercept probability (IP) is proposed and demonstrated. Furthermore, the Monte Carlo simulation is provided to justify the correctness of the mathematical, analytical expression of the lower and upper bound IP. The results show that the analytical and the simulation curves are the same in connection with the primary system parameters

Risk analysis of energy in Vietnam

The purpose of the paper is to estimate market risk for the ten major industries in Vietnam. The focus is on the Energy sector, which has been designated as one of the four key industries, together with Services, Food, and Telecommunications, targeted for economic development by the Vietnam Government through to 2020. Oil and Gas is a separate energy-related major industry. The data set is from 2009 to 2017, which is decomposed into two distinct sub-periods after the Global Financial Crisis (GFC), namely the immediate post-GFC (2009-2011) period and the normal (2012-2017) period, in order to identify the behaviour of market risk for Vietnam major industries. Two widely-used approaches to measure and analyze risk are used in the empirical analysis, namely Value-at-Risk (VaR) and Conditional Value-at-Risk (CVaR). The empirical findings indicate that Energy and Pharmaceuticals are the least risky industries, whereas Oil and Gas and Securities have the greatest risk. In general, there is strong empirical evidence that the four key industries display relatively low risk. For public policy, the Vietnam Government’s pro-active emphasis on the targeted industries, including Energy, to achieve sustainable economic growth and national economic development, seems to be working effectively

Area yield crop insurance in Vietnam : an analysis from the demand side

When setting prices for each province, crop insurance companies should pay more attention to the relative level of basic risk and the correlation of losses across regions, instead of only focusing on the general level of risk exposure of each region. If farmers receive enough information about the insurance, the demand should be higher than the current rate of uptake. This study analyzes the demand of rice farmers for area yield crop insurance, which was designed and piloted during the period of 2011 - 2013 in Vietnam according to Decision No. 315/QD-TTg of the Prime Minister

Gauge Bosons in the 3-3-1 Model with Three Neutrino Singlets

We show that the mass matrix of electrically neutral gauge bosons in the recent proposed  model based on $\mathrm{SU}(3)_C\otimes \mathrm{SU}(3)_L\otimes \mathrm{U}(1)_X$ group with three neutrino singlets [9] has two exact eigenvalues and corresponding eigenvectors. Hence the neutral non-Hermitian gauge boson $X^0_\mu$ is properly determined.With extra vacuum expectation values of the Higgs fields, there are mixings among charged gauge bosons $W^\pm$ and $Y^\pm$ as well as amongneutral gauge bosons $Z, Z'$ and $X^0$. From the $W$ boson decay width, we get lower bound on  scale of the model about few TeVs

Market risk analysis of energy in Vietnam

The purpose of this paper is to evaluate and estimate market risk for the ten major industries in Vietnam. The focus of the empirical analysis is on the energy sector, which has been designated as one of the four key industries, together with services, food, and telecommunications, targeted for economic development by the Vietnam Government through to 2020. The oil and gas industry is a separate energy-related major industry, and it is evaluated separately from energy. The data set is from 2009 to 2017, which is decomposed into two distinct sub-periods after the Global Financial Crisis (GFC), namely the immediate post-GFC (2009–2011) period and the normal (2012–2017) period, in order to identify the behavior of market risk for Vietnam’s major industries. For the stock market in Vietnam, the website used in this paper provided complete and detailed data for each stock, as classified by industry. Two widely used approaches to measure and analyze risk are used in the empirical analysis, namely Value-at-Risk (VaR) and Conditional Value-at-Risk (CVaR). The empirical findings indicate that Energy and Pharmaceuticals are the least risky industries, whereas oil and gas and securities have the greatest risk. In general, there is strong empirical evidence that the four key industries display relatively low risk. For public policy, the Vietnam Government’s proactive emphasis on the targeted industries, including energy, to achieve sustainable economic growth and national economic development, seems to be working effectively. This paper presents striking empirical evidence that Vietnam’s industries have substantially improved their economic performance over the full sample, moving from relatively higher levels of market risk in the immediate post-GFC period to a lower risk environment in a normal period several years after the end of the calamitous GFC

Epidemiological and molecular characteristics of Infectious bursal disease virus naturally infected in the broiler flocks in the Mekong Delta of Vietnam during 2015 and 2018

Infectious bursal disease is a highly contagious and economically devastating disease in the poultry industry worldwide caused by Infectious bursal disease virus (IBDV). However, the data on epidemiological and molecular characteristics of the IBDV outbreak in broiler flocks in the Mekong Delta of Vietnam is unclear. Herein, the epidemiological data of IBDV–positive flocks over a period of 2015–2018 were recorded and the hypervariable region of the VP2 gene of IBDV was amplified to analyze the local phylogeny. The current investigation showed that the overall morbidity and mortality rates of IBDV–positive flocks were 45% and 4.81%, respectively. The IBDV–positive birds occurred clinical signs and macroscopic findings involved with the very virulent (vv) IBDV outbreak. Epidemiological results revealed that IBDV was frequently infected in broiler flocks at 12–42 days, and birds belonging to Tau Vang and Binh Dinh breeds were more sensitive to IBDV. Also, the morbidity rate of IBDV was dramatically decreased in the open farming system. Flocks with complete vaccination significantly dropped morbidity in comparison with other groups. Regarding phylogenetic analysis, all identified IBDV sequences clustered in the same branch of vv phenotype and closely homology with prior strains circulated in Vietnam and other countries. These findings first indicated the epidemiological characteristics of the IBDV–positive broiler flocks in the Mekong Delta and highlighted the IBDV strain circulating in this region

Pharmacist-Led Intervention to Enhance Medication Adherence in Patients With Acute Coronary Syndrome in Vietnam:A Randomized Controlled Trial

Background: Patient adherence to cardioprotective medications improves outcomes of acute coronary syndrome (ACS), but few adherence-enhancing interventions have been tested in low-income and middle-income countries. Objectives: We aimed to assess whether a pharmacist-led intervention enhances medication adherence in patients with ACS and reduces mortality and hospital readmission. Methods: We conducted a randomized controlled trial in Vietnam. Patients with ACS were recruited, randomized to the intervention or usual care prior to discharge, and followed 3 months after discharge. Intervention patients received educational and behavioral interventions by a pharmacist. Primary outcome was the proportion of adherent patients 1 month after discharge. Adherence was a combined measure of self-reported adherence (the 8-item Morisky Medication Adherence Scale) and obtaining repeat prescriptions on time. Secondary outcomes were (1) the proportion of patients adherent to medication; (2) rates of mortality and hospital readmission; and (3) change in quality of life from baseline assessed with the European Quality of Life Questionnaire - 5 Dimensions - 3 Levels at 3 months after discharge. Logistic regression was used to analyze data. Registration: ClinicalTrials.gov (NCT02787941). Results: Overall, 166 patients (87 control, 79 intervention) were included (mean age 61.2 years, 73% male). In the analysis excluding patients from the intervention group who did not receive the intervention and excluding all patients who withdrew, were lost to follow-up, died or were readmitted to hospital, a greater proportion of patients were adherent in the intervention compared with the control at 1 month (90.0% vs. 76.5%; adjusted OR = 2.77; 95% CI, 1.01-7.62) and at 3 months after discharge (90.2% vs. 77.0%; adjusted OR = 3.68; 95% CI, 1.14-11.88). There was no significant difference in median change of EQ-5D-3L index values between intervention and control [0.000 (0.000; 0.275) vs. 0.234 (0.000; 0.379); p = 0.081]. Rates of mortality, readmission, or both were 0.8, 10.3, or 11.1%, respectively; with no significant differences between the 2 groups. Conclusion: Pharmacist-led interventions increased patient adherence to medication regimens by over 13% in the first 3 months after ACS hospital discharge, but not quality of life, mortality and readmission. These results are promising but should be tested in other settings prior to broader dissemination
