目的用音樂療法作為放鬆的介入方式,以減輕結腸鏡檢查者術中的不適,促進結腸鏡檢查的進程及改善舒適度。方法2021年4月12日~5月18日,於澳門某醫院對104位結腸鏡檢查者進行研究,分為研究組及對照組(每組各52人)。研究組結腸鏡檢查者介入音樂療法,對照組予常規照護,比較兩組疼痛評分(numerical rating scale,nRS)、收縮壓、舒張壓、心率及結腸鏡檢查進鏡時間的差異。結果兩組研究參與者在nRS疼痛評分、術中及術後血壓及心率無差異;兩組結腸鏡檢查的進鏡時間均數沒有顯著差異;但進鏡時間≦10分鐘組(非困難腸鏡組)與>10分鐘組(困難腸鏡組)則存在組間差異,在非困難腸鏡組中,研究組進鏡時間為6.2±1.6分鐘,對照組進鏡時間為7.2±1.6分鐘(T=-2.075,P<0.05);困難腸鏡組則沒有顯著差異。結論音樂放鬆療法對結腸鏡檢查者的疼痛緩解、血壓及心率穩定沒有顯著作用,但仍可縮短“非困難腸鏡”的進鏡時間。

Camera calibration is a critical process in photogrammetry and a necessary step to acquire 3D information from a 2D image. In this paper, a flexible approach for CCD camera calibration using 2D direct linear transformation （DLT） and bundle adjustment is proposed. The proposed approach assumes that the camera interior orientation elements are known, and addresses a new closed form solution in planar object space based on homogenous coordinate representation and matrix factorization. Homogeneous coordinate representation offers a direct matrix correspondence between the parameters of the 2D DLT and the collinearity equation. The matrix factorization starts by recovering the elements of the rotation matrix and then solving for the camera position with the collinearity equation. Camera calibration with high precision is addressed by bundle adjustment using the initial values of the camera orientation elements. The results show that the calibration precision of principal point and focal length is about 0.2 and 0.3 pixels respectivelv, which can meet the requirements of close-range photogrammetry with high accuracy.

Introduction The main objective of any healthcare establishment must be to ensure the quality of patient care and customer satisfaction. It is necessary to regularly assess patient satisfaction. The aim of this study was to assess the level of satisfaction of customers aged over 18 years attending the emergency department of the health center. Methodology This was a descriptive and analytical cross-sectional study of patients aged 18 years and over, who attended the Samu Municipal emergency department between 02 and 30 May 2023. The satisfaction index was determined using the adapted 2009 SAPHORA-MCO questionnaire and the Likert satisfaction scale. Results A total of 400 patients were surveyed. The average age was 35 years, with a standard deviation of 14.7. Of those surveyed, 51% were women, 87% were educated, 50% lived in Grand Yoff and 59.5% were unemployed. Satisfaction levels linked to perception of the cost of care (72%), waiting time (64.3%), information given to patients (69.1%) and pain management (74 .5%) are fair. On the other hand, the levels of satisfaction linked to administrative procedures (82.5%), staff attitudes towards patients (84%), staff availability (86.4%), patient privacy (89.2%), general atmosphere (87.2%), staff competence (87.3%), and the effectiveness of care (89.4%) were satisfactory. The average waiting time was 38 minutes. However, 32% of patients waited less than 30 minutes and 92% less than an hour. The satisfaction index linked to administration and reception was 72.9% and 79.85%, respectively. The satisfaction index linked to the administration and technical quality of care is equal to 85.8% and 83.7%, respectively. The overall satisfaction index is equal to 80.6%;the level of satisfaction of users of the health structure is satisfactory. Conclusion Patient satisfaction is an essential part of quality care. Patient satisfaction must be based on effective communication from the healthcare team and the creation of a patient-caregive

用于高压电触头材料的90W-10Cu难熔合金由于具有高熔点和高比重差异,在高温长时间的粉末冶金过程中存在致密化困难和晶粒异常长大而影响其性能。在常规热压烧结基础上,振荡热压烧结(HOP)技术采用一定频率的循环振荡单轴压力代替静单轴压力,可快速促进陶瓷等材料的致密化。因此,为了研究振荡热压烧结对90W-10Cu难熔合金的低温烧结效果,本文将振荡热压烧结技术应用到90W-10Cu(质量分数)难熔合金的制备中,研究了烧结温度(1000~1300℃)对其微观组织、致密度、晶粒尺寸、硬度及电导率性能的影响。研究结果发现,振荡热压烧结90W-10Cu合金由W相基体和Cu相黏结相组成。随着烧结温度的升高,90W-10Cu难熔合金的致密度逐渐增大,在烧结温度最高为1300℃时,其致密度最高可达到99.35%,均高于同等温度下的热压烧结样品的致密度;而晶粒尺寸仅为4.97μm左右,没有异常长大,达到了细化晶粒的效果;同时,其W晶粒邻接度逐渐降低,合金的微观组织均匀性得到优化和改善;维氏硬度和电导率分别达到225.78 HV_(30)和27.88%国际退火铜标准(IACS),高于同等温度甚至高100℃时的热压烧结体,性能得到显著提升,达到了低温烧结效果。结果表明,振荡热压烧结能够有效地促进90W-10Cu难熔合金的致密化,降低烧结温度和抑制晶粒生长,显著优化其微观组织均匀性,有利于在较低温度下获得高致密度、晶粒细小、高硬度和高电导率的90W-10Cu难熔合金材料。

为研究一、二级旋流器气量分配对燃烧室排放性能的影响,在总气量恒定条件下,针对配装气量比分别为0.85和1.1两种方案双级轴向旋流器的全环燃烧室开展了地面慢车、空中慢车和起飞状态下的排放试验。结果表明:气量比从0.85增加到1.1,空中慢车和起飞状态氮氧化物(nOx)排放分别降低33%~52%和14%~38%,地面慢车状态CO和未燃碳氢(UHC)排放分别降低23%~49%和32%~36%。地面慢车状态两方案旋流器对应的nOx排放差异不大,且排放值均较低。CO和UHC排放主要集中在地面慢车状态,随着状态增大,CO和UHC排放量逐渐降低,且空中慢车和起飞状态对应的CO和UHC排放量差异不大。在本文试验范围内,全环燃烧室CO排放指数随着nOx排放指数的增加呈现幂函数下降,随着UHC排放指数的增加呈现对数上升。

Introduction: Rabies is a serious disease, as it is always fatal, but it can be prevented by sero-vaccination. It is a neglected tropical disease endemic in Asia and Africa. The aim of this study was to assess knowledge, attitudes and practices regarding rabies and to determine the factors associated with them among people aged 18 and over in the commune of niakhène. Methods: This was a cross-sectional, descriptive and analytical survey of subjects aged 18 and over living in the commune of niakhène. A sample of 300 individuals was drawn from a two-stage cluster survey stratified by age and sex. bivariate analysis was performed using association tests. Results: The mean age of respondents was 35.3 ± 16.9 years. It was noted that 67% (201) of respondents had a good knowledge of rabies. The results showed that 7.3% (22) of respondents owned a dog. Of the 278 people who did not own a dog, 78.4% (218) said they would have vaccinated their dog if they had had one. It should be noted that 83.7% (251) of respondents said they would go to a health facility if an animal bit them. none of the dog owners had vaccinated their dogs against rabies. Of the 41 people exposed to rabies, 39% went to a health facility. The age and education of the respondents had statistically significant associations with knowledge of rabies. Respondents’ age and education were statistically significantly related to whether they had vaccinated a domestic dog. The age, education and economic well-being quintile of respondents’ households had statistically significant associations with the use of a health facility in the event of being bitten or scratched by an animal vector. The education of respondents who had been bitten by an animal vector was statistically significantly associated with the use of a health facility. Conclusion: It would be imperative for human and animal health authorities to collaborate in a “One Health” approach in order to increase knowledge and promote the adoption of good pract

网络教学资源的普及使得资源评价的文本数据规模逐步增大.传统的有监督学习文本分类对标注数据的依赖度较高,需要足够的数据量和高质量数据才能得到良好的结果.在网络教学资源的评价文本工作中,由于标注数据难以获取且质量参差不齐,使得这一任务的难度越来越高.针对这一困难,提出一种TS-Aug半监督自训练方案,通过添加无标签数据并进行伪标签训练,能在强力数据增广的作用下大幅扩充样本集,解决数据增广中的过拟合风险.首先利用标注数据和弱增广策略进行初始化监督训练,然后利用无标注数据和强增广策略进行半监督训练,最后使用标注数据进行微调监督训练.在自建的在线课程评论数据中,能将分类F 1-Score从0.88提升至0.95,表明TS-Aug半监督自训练方案在文本分类任务中具有较好的应用前景.
