El objetivo de estudio es conocer los tipos de saques utilizados, dependiendo el momento del set en el que se producen. Este estudio ha sido desarrollado durante el torneo Nestea Spanish Master de Vóley Playa disputado en Valencia en el año 2006. La muestra de estudio la componen 10 jugadoras que conforman 5 equipos con un total de 4 encuentros analizados que suman 331 saques analizados. El análisis de las videograbaciones se llevó a cabo con el software SportCode Pro v.8.5.2. Los saques se clasificaron dependiendo del momento en el que se produjeron, siendo la franja 1 (del punto 1 al 7), franja 2 (del punto 8 al 14) y franja 3 (del punto 15 al 21). El análisis de datos se llevo a cabo con el software SPSS v.19. La prueba Chi-cuadrado, estableció diferencias significativas entre los diferentes tipos de saques para la franja 1 y 3 (p<.05), pero no se establecieron diferencias significativas en la franja 2 para los tres tipos de saque utilizado (p>.05). Se experimenta una disminución en el uso del saque en potencia (SP) de la franja 1 (84.1%) con respecto al de la franja 3 (4.8%), mientras que el saque flotante (SF) aumenta de la franja 1 (13.5%) a la franja 3 (81%). Finalmente el saque flotante (SF) en salto aumentan de la franja 1 (2.4%) a la franja 2 (28%) y decrece de esta última a la franja 3 (14.3%).Palabras clave: Vóley Playa, análisis del rendimiento, SportCode, saques vóley playa.Abstract: The aim of study was to determine the types of serves used, depending on the time of the set in which they occur.

The COVID-19 outbreak is currently spreading to all regions of Indonesia. This virus was suspected to spread from Wuhan at the end of December 2019. Restrictions on people’s movements are one of the government policies that aim to reduce the spread of COVID-19. To find out the performance of government policy, a study on the implementation of restrictions policy to prevent the spread of COVID-19 in West Sumatra has been conducted. This study used the before-after method as data analysis, then the data was examined using the Chi-Square test. Based on the results of data analysis, it was found that the movement of people after the implementation of restrictions movement policy was decreased significantly. The decrease in the need to leave the house was average 57.7%, frequency leaving the house more than 5 times decreased by 80%. Time of leaving the houses in the day, in the afternoon and at night decreased more than 50%, the use of vehicle modes decreased by 14.9% and the number of people traveling outside the house decreased by 23.2%. The performance of restrictions on people’s movement policy in West Sumatra was still not optimal, because many people did not know the detail of policies.

In a clinical study we compared three different types of therapy in chronic maxillary sinusitis. 45 patients, 3-40 years old, were treated, 19 with antibiotics, 18 with acupuncture and 8 with Laser-acupuncture. There was no statistical difference of results between Laser-therapy and antibiotics (Chi-Square-Test). Compared to previous treatments with antibiotics, results and duration of improvement was significantly better after acupuncture. Conclusion: Acute sinusitis, especially of frontal sinus and in younger children, will better be treated by antibiotics because of the danger of osteomyelitis and meningitis. Acupuncture should be tried in chronic and recurrent stages after exclusion of large adenoids in children or bone inhibition of sinus clearance, especially before an invasive operation like removal of sinus mucosa is carried out.

The outbreak of COVID-19 has constantly exposed health care workers (HCWs) around the world to a high risk of infection. To more accurately discover the infection differences among high-risk occupations and institutions, Hubei Province was taken as an example to explore the spatiotemporal characteristics of HCWs at different scales by employing the chi-square test and fitting distribution. The results indicate (1) the units around the epicenter of the epidemic present lognormal distribution, and the periphery is Poisson distribution. There is a clear dividing line between lognormal and Poisson distribution in terms of the number of HCWs infections. (2) The infection rates of different types of HCWs at multiple geospatial scales are significantly different, caused by the spatial heterogeneity of the number of HCWs. (3) With the increase of HCWs infection rate, the infection difference among various HCWs also gradually increases and the infection difference becomes more evident on a larger scale. The analysis of the multi-scale infection rate and statistical distribution characteristics of HCWs can help government departments rationally allocate the number of HCWs and personal protective equipment to achieve distribution on demand, thereby reducing the mental and physical pressure and infection rate of HCWs.

  Introduction: Customers sometimes question the freshness of milk inside thermal containers in coffee shops. Milk that is kept between 4°C to 60°C can support the growth of pathogens, hence it should be kept below 4°C. Thermal containers are often advertised as being able to retain the temperature of their contents for a prolonged period of time. Yet, the extent of their temperature retention capacity is not clearly defined by the manufacturers. This study investigated the effectiveness of the 1.5 Liter Thermos® Double Wall Vacuum Stainless Steel Serving Carafe thermal container in keeping milk at ≤4°C when it was filled to different volumes and with different types of milk over a nine hour period. Methods: Four tests were carried out in this study: The 1.5L Skim Milk, The 1.5L Creamo, The 0.75L Skim Milk and The 0.75L Creamo Test. For each test, the milk was placed into the 1.5L Thermos® Double Wall Vacuum Stainless Steel Serving Carafe with the initial temperature between 3.1°C to 3.4°C. Change in temperature was recorded for nine hours using the Thermocouple data logger. Results: The descriptive data demonstrates that the mean temperatures over the nine-hour period for The 1.5L Skim Milk Test, The 1.5L Creamo Test, The 0.75L Skim Milk Test and The 0.75L Creamo Test were 4.41±0.88°C, 4.51±0.95°C, 5.59±1.52°C and 6.05±1.77°C, respectively. MANOVA results suggested that “volume”, “time”, “type of milk”, “volume and time”, “volume and type of milk”, “time and type of milk”, and “volume, time and type of milk” did have effects on the temperature retention capacity of the thermal container with p-values <0.05. The temperatures of all samples were <4°C at hour zero. All of the samples’ temperatures began to increase once they were inside the thermal container and all of the samples entered the danger zone (>4°C) after four hours. A Chi Square test was conducted to determine whether Creamo or skim milk was safer (≤4°C) from hour one to four. Results showed that 123/240 (51%) skim milk and 110/240 (46%) Creamo samples were safe, but the result was not statistically significant. Conclusion: This study’s results indicate that the tested thermal container had a better cold temperature retention capacity when it was filled up (1.5L) compared to when it was only half filled (0.75L). In addition, when the thermal container was filled with skim milk, it also had a better cold temperature retention capacity compared to Creamo. Finally, this specific thermal container was not successful in maintaining the temperature of milk out of the danger zone (≤4°C) after four hours. These results should be disseminated to Environmental Health Officers whose job it is to keep the public safe from foodborne illnesses. As well, policies should be established pertaining to time permitted to keep milk in thermal containers.

AbstractThis study aims to assess the awareness and opinions of employees and children living in foster care homes about the Romanian Clean Air Legislation. The assessment was performed six months after the implementation of the antitobacco legislation (Romanian Law no.15/2016), in three Romanian counties (Alba, Mures, and Covasna) including 178 employees and 368 children from 59 foster care homes. Data were collected using an anonymous paper and pencil questionnaire. Descriptive statistics and chi-square test were used for data analysis (significant difference if p < 0.05). Almost one third of the employees and children were smokers from the forest care homes. Nearly, all the employees and most of the children were aware of the legislation, most of them have also noticed some kind of measures taken by foster care homes against smoking. As claimed by smokers, almost two-thirds of them smoked like they used to do before the legislation, more than a quarter stated that they decreased the number of daily smoked cigarettes and nearly a quarter intended to quit smoking in the future. A half year after the implementation of the legislation most of the employees and children living in foster care homes admitted that they knew about the change and it affected their smoking habits. Most of them have also observed some kind of measures taken against smoking. Despite these measures there were still smokers in the foster care homes, so there would be a need for more campaigns against smoking in the future.

Adherence to hand hygiene recommendations by health care workers (HCWs) participate to minimize healthcare-associated infections. There are few studies, to our present state of knowledge, which interested in the rate of adherence in Algerian hospitals and no one on the associated factors with the non-adherence by HCWs. The objective was to determine the rate of adherence with WHO's hand hygiene recommendations and to identify factors associated with non-adherence, in a regional university hospital. The method used was the direct observation, based on the recording of hygienic actions in opportunities for HCWs in front of the WHO's five indications. To determine the factors associated with non-adherence, a questionnaire was administrated to HCWs. The relationship between the different factors and the achievement of a hygiene action was evaluated by Pearson's Chi-square test. 503 opportunities for hand hygiene were observed among 206 HCWs, during 19 observation sessions. Simple handwashing was noted in 19% of hand hygiene actions. The overall adherence was 21 %. There was a wide variation in the adherence rates between the different departments and the different types of HCWs. There was a statistically significant association (p
