Many households are involved in informal alcohol production for income purposes, resulting in alcohol being easily available. Alcohol is consumed mostly by adults and young adults, waragi （a local brew） being high on the menu. There is a high prevalence of alcohol consumption at Makerere University so in our study we set out to assess the knowledge about dangers of alcohol consumption among these students. It was a cross-sectional descriptive study. The target population was undergraduate students of Makerere University. Data were collected using self-administered questionnaires and focus group discussions. We interviewed 435 University students, 236 （54.3%） males and 199 （45.7%） females. Median age was 21 years, similar across gender. There were more participants from year one to three compared to years four and five. Majority of the students were consuming alcohol 242 （55.6%）, 49 （11.3%） had stopped and 144 （33.1%） had never consumed alcohol. A higher proportion of males consumed alcohol compared to females; 60.2% and 50.2% respectively. Some reasons given for alcohol consumption were： peer pressure, coping with stressful situations, celebration and the need for adventure. The students were knowledgeable about the dangers of alcohol consumption like liver disease, violence, mental illness, cancer, diabetes mellitus, financial loss and death. Despite the vast knowledge about the dangers of alcohol consumption, some students were reluctant to stop consuming alcohol, so fighting this habit in this population is important. Parents and students need to be mindful of where to reside so as to avoid bad company. Some of the students who stopped consuming alcohol attributed it to concern from a relative, friend or health worker, so involving the entire public could go a long way in the fight against alcohol abuse as well as strict regulation of physical availability of alcohol on the university campus.Abstract： Consumption of alcohol and other alcoholic beverages is widespread in Uganda and it is the highest per capita consumer of alcohol in Africa.

Methods: A total of 20 midwives and public health nurses were selected as participants. Teaching materials and anonymous self-administered questionnaires were distributed, and the participants were asked to view the teaching materials and fill in the questionnaires. Retrieval was done by mail. The teaching materials included digital content, such as videos, sounds, and characters, which incorporated dangerous situations, preventions, and innovations in ablution and bathing procedures. The analysis was conducted by simple tabulation for each survey item. The free description was coded to preserve anonymity. This study was conducted with the approval of the Research Ethics Review Board of the authors’ affiliated university. Results: The teaching materials were found to be appropriate in terms of suitability to purpose, degree of difficulty of content, ease of viewing the videos, validity of time, appropriateness of expression, and usability. Conclusions: Ablution teaching materials that are used at the present time do not focus on dangers, and to date, no resources on bathing have been used as teaching materials. The created teaching materials in this study can be viewed multiple times, and mothers and family members who are unfamiliar with ablution and bathing can acquire knowledge regarding dangers and danger prevention. The addition of specific preventive measures and countermeasures for the occurrence of danger, along with practice, would result in the development of further appropriate teaching materials to reduce danger and alleviate anxiety.展开更多

The teaching materials included digital content, such as videos, sounds, and characters, which incorporated dangerous situations, preventions, and innovations in ablution and bathing procedures. The analysis was conducted by simple tabulation for each survey item. The free description was coded to preserve anonymity. This study was conducted with the approval of the Research Ethics Review Board of the authors’ affiliated university. Results: The teaching materials were found to be appropriate in terms of suitability to purpose, degree of difficulty of content, ease of viewing the videos, validity of time, appropriateness of expression, and usability. Conclusions: Ablution teaching materials that are used at the present time do not focus on dangers, and to date, no resources on bathing have been used as teaching materials. The created teaching materials in this study can be viewed multiple times, and mothers and family members who are unfamiliar with ablution and bathing can acquire knowledge regarding dangers and danger prevention. The addition of specific preventive measures and countermeasures for the occurrence of danger, along with practice, would result in the development of further appropriate teaching materials to reduce danger and alleviate anxiety.
文摘Operating Room is an important place for surgical diagnosis and treatment and rescue of patients. With the rapid development of medical technology, high, precision, sharp continuous development, operating room safety management is particularly important. The error of the counting of the surgical articles causes the foreign body left in the patient’s body, which will cause irreversible damage to the patient and even cause the medical dispute and touch the legal problem. Operation items inventory system is an important working system in the operating room. Scientific and standardized methods and systems for counting surgical instruments and dressings during operation can prevent foreign bodies from being left in the body, prevent errors and accidents in the operating room, and are very important for ensuring the safety of the operation of patients. In order to ensure the safety of patients, it is necessary to ensure the correct inventory of surgical items. The factors affecting the accuracy of item counting in the operating room and the preventive measures are summarized as follows.

文摘Improving the danger prediction during driving can significantly reduce the risk of accidents.However,previous danger prediction training systems had not been sufficiently effective owing to the lack of realism.In this study,we propose an immersive training system for danger prediction training using virtual reality(VR)technology.This system provides drivers with a highly realistic training environment with 360°videos viewed with VR goggles.Users can practice various dangerous scenarios in an environment that simulates a real-driving situation.In addition,we introduced a system to select dangerous spots with a controller and implement training schemes on a voluntary basis.This setup enables them to train in a highly interactive state.In addition,we proposed a method to express multiple indices numerically so that users can understand the training effect.We tested the effect of the system on the danger prediction abilities of various users with two experiments by using this approach.These results show that our system was more effective in improving the driver’s danger prediction ability than previous systems.
文摘Objective: To explore the clinical effect and application value of pregnancy health education in outpatient nursing of Obstetrics and gynecology.Methods 100 pregnant women treated in our hospital from January 2017 to January 2019 were randomly divided into observation group (n = 50) and control group (n = 50).The control group received obstetrics and gynecology nursing, and the observation group carried out health knowledge education during pregnancy on the basis of it.The delivery mode and complications, incidence of postpartum hemorrhage, full-term pregnancy body mass index and labor process time were compared between the two groups.Results the natural delivery rate and cesarean section rate in the observation group were 84.00% and 4.00%, which were significantly better than 62.00% and 14.00% in the control group (P < 0.05);The incidence of complications in the observation group was 42.00%, lower than 88.00% in the control group (P <0.05);The incidence of postpartum hemorrhage in the observation group was 4.00%, significantly lower than 12.00% in the control group, but the results of this study were not statistically significant (P > 0.05).The body mass index of full-term pregnancy in the observation group was significantly better than that in the control group (P < 0.05);Conclusion pregnancy health education can effectively reduce the occurrence of obesity and pregnancy complications. Through the guidance of delivery skills, it can effectively shorten the labor process, reduce the incidence of dystocia, midwifery and postpartum hemorrhage, and then significantly improve the natural delivery rate.

文摘Precise forecasts of wildfire danger are crucial for proactive fuel management and emergency responses,yet they pose a challenge at the subseasonal scale due to limitations in prediction capabilities and a gap between forecast outputs and the needs of decision-makers.This study introduces an innovative hybrid modeling framework that integrates artificial intelligence(AI)with climate dynamic prediction systems to accurately forecast High Fire-Danger Days(HFDDs)for the following month.These HFDDs are derived from historical satellite fire data and the optimum fire danger index,with a particular focus on Southwest China as a case study.The AI module,based on the ResNet-18 neural network model,integrates observational and physically constrained analysis to establish links between HFDDs and optimal predictors of atmospheric circulation from both the concurrent and preceding months.Leveraging climate dynamical forecasting,this hybrid model provides more reliable deterministic predictions for monthly HFDDs than conventional methods that rely solely on terrestrial variables such as precipitation.More importantly,the integration of dynamical ensemble prediction enhances the model’s capability for skillful probabilistic predictions of HFDDs,facilitating the creation of customized fire danger outlooks and emergency action maps tailored to stakeholders’needs.The model’s added economic value was also evaluated,demonstrating its potential to improve decision-making in disaster management and bridge the“last-mile gap”in climate service delivery.This work contributes to the Seamless Prediction and Services for Sustainable Natural and Built Environment(SEPRESS)Program(2025–32),under the United Nations Educational Scientific and Cultural Organization(UNESCO)International Decade of Sciences for Sustainable Development(2024–33).

文摘The Three Gorges Reservoir area hosts numerous high-risk columnar rock masses,but predicting their full-process of collapse dynamics in narrow-deep terrains remains challenging.This study investigated the Changdongzi columnar dangerous rock mass(CCDRM)through field surveys and simulated its collapse dynamics with Material Point Method(MPM),and analyzed the collapse-diffusionsurge generation mechanisms.Field investigations revealed a 0.8 m-thick lotus-like extrusion structure at the base,severely degraded by cyclic water fluctuations,predisposing the rock mass to base-crushing failure.Numerical simulations indicate collapse velocities up to 42 m/s,amplified spreading with a 318 m deposition range and 11 m maximum thickness,and two major collisions causing 50%-60%velocity reduction.Gully topography buffers kinetic energy,retaining 5%debris on slopes and channeling 7%into the river.High-speed river impact generates a 20 m-diameter cavity,producing an 11 m surge,identifying the Guandukou Town waterfront 1.2 km downstream as a high-risk zone.These results clarify the collapse mechanisms of columnar dangerous rock mass and inform its hazard mitigation strategies.
文摘本刊上期刊登了一篇题为Prescribed Killers的文章。该文告诉我们:为什么医生为治病而开的药方可能成为可怕的隐形杀手。“吃药吃死人”,决非耸人听闻之言！在美国,可靠的数据揭示,药物成了当今美国的第四杀手:Anddoctors and patients need to remember that the cure sometimes is worse than thedisease.本期选登了一篇来稿,题目是The Dangers of Self-Dosing,联系到上期的那篇文章,我们不妨可把本文的标题改为:Self-Prescribed Killers。不知读者以为如何?由于医药知识的普及和媒介(尤其是电视广告)在作用,再加上国人有句俗话:久病成良医。所以,遇到头疼脑热,或者其他不舒服,就随便抓把药吃吃。这种现象似有愈演愈烈之势。本文刊登在1998年7月13日的U.S News ＆ WorldReport上、我们非常高兴收到陆书雏老师的来稿,因为,此稿和上期的Prescribed Killers正好构成“姊妹篇”。也许,在你准备自作良医,动手“抓药”的时候,突然想起曾经读过的本刊的这篇文章。那么,那就是《科技英语学习》最高兴的事情了。
