Design of Intelligent Drunk Driving Detection System Based on Internet of Things

In recent years,with the rapid development of China’s economy and the continuous improvement of people’s living standards,the number of motor vehicles and the number of drivers in the country have grown rapidly.Due to the increase in the number of vehicles and the number of motorists,the traffic accident rate is increasing,causing serious economic losses to society.According to the traffic accident statistics of the Ministry of Communications of China in 2009,more than 300,000 car accidents occurred in the year,most of which were caused by drunk driving.Therefore,this paper proposes a design scheme based on the Internet of Things-based vehicle alcohol detection system.The system uses STM8S003F3 single-chip microcomputer as the main control chip of the system,combined with alcohol sensor MQ-3 circuit,LCD1602 liquid crystal display circuit,buzzer alarm circuit and button circuit to form a complete alcohol detection module hardware system.The main functions of the system are as follows:the alcohol sensor in the car detects the driver’s alcohol concentration value,and displays the value on the LCD screen.The buzzer alarm is exceeded and the information is sent to the traffic police department and the family’s mobile phone through the GPRS module.The system can effectively make up for the shortcomings of traffic police detection,which has certain research significance.

Predicting Alcohol Consumption in Hospitality Populations Using Sense of Coherence

This paper aims to introduce the claim that hospitality students and hospitality employees drink more alcohol than other students and employee groups and to explore and explain this alcohol consumption disparity using the sense of coherence （SOC） construct. Using a web-based questionnaire, college students were recruited, surveyed, and classified into hospitality and non-hospitality majors. Self-reported alcohol consumption, SOC, and a variety of demographic variables were measured. A total of 930 students participated of which 59.4% were female and 28% were hospitality majors. About 47% of hospitality students, 33% of other majors, 43% of women, and 38% of men were classified as at-risk consumers of alcohol. The overall SOC score was about 139 with a range of 69-191. None of the sub-populations differed significantly in SOC. While SOC does not predict major or occupational choice, SOC is a predictor of risky alcohol consumption.

Alcohol-related liver disease

Among individuals with known alcohol use disorder(AUD),the prevalence of alcoholic fatty liver disease(AFLD)is present in 25-90%of cases(1).Shroff et al.(1)report that the annual progression to cirrhosis is 3%in the presence of AFLD,10%in case of alcohol-related steatohepatitis(ASH)and 8%with any grade of pre-cirrhotic fibrosis.Alcohol-related liver disease(ALD)is the cause of 36%of cases of cirrhosis in the United States and nearly one half of cirrhosis-related deaths worldwide(1).Ethanol is a recognized carcinogen for several malignancies with the risk starting at low dose(10 gr/1 unit/day)(2).The link between alcohol consumption(AC)and hepatocellular carcinoma(HCC)is well known:various evaluations carried out by both USA and Italian groups indicate that such a correlation is present in 32%to 45%of cases(2).With the reduction of hepatitis C virus(HCV)cases,AC will become the main cause of HCC in Western countries.Furthermore,ALD and metabolic syndrome(MS)are currently the main causes of liver transplantation(LT)(3).

Alcohol Test

The recent alcohol tax increase poses a challenge to China’s white spirits makers Alcohol, rather than wine, is an in-dispensable component to Chinese table culture. The financial crisis has failed to affect white spirits sales, but an alcohol tax increase might.
