Although the system parameters may be tuned very well, due to the machine and human factors involved in the production line some deficiencies may occur in product. It is important to detect such problems as early as possible. Surface defects and dimensional deviations are the most important quality problems. In this study, it is aimed to develop an approach to measure the dimensions of metal profiles by obtaining images of them. This will be of use in detecting the deviations in dimensions. A platform was introduced to simulate the real-time environment and images were taken from the metal profile using 4 laser light sources. The shape of the material is generated by combining the images taken from different cameras. Real dimensions were obtained by using image processing and mathematical conversion operations on the images. The results obtained with small deviations from the real values showed that this method can be applied in a real-time production line.展开更多

Our objective was to determine the prevalence and factors associated with CS at GPHC from July to September 2022. Methods: A cross-sectional study was carried out and data were collected from 1296 mothers, who met the inclusion criteria, through face-to-face interviews after obtaining prior informed consent. We performed descriptive analyses both for the outcome and independent variables. Bivariate and multiple logistic regression were used to identify factors associated with CS with a p-value Results: The prevalence of CS at GPHC was 28.9% (95%CI: 26.5-31.5). Factors associated factors with CS were mothers aged 20 to 34 years (AOR: 1.56, 95%CI: 1.02 - 2.39, P = 0.039);mothers who received more than three minimum wages (AOR: 1.95, 95%CI: 1.29 - 2.97, P = 0.002) and who attended prenatal care at both public and private health facilities (AOR: 2.49, 95% CI: 1.19 - 5.22, P = 0.022). Likewise, the highest Odds of CS were observed in mothers with gestational hypertension (AOR: 2.00, 95%CI: 1.35 - 2.96, P Conclusion: The prevalence of CS is higher than the ideal rate recommended by the International Healthcare Community. More studies are needed to understand the reasons for such high prevalence at GPHC.展开更多

Rupture of the uterus is a devastating complication in trial of labour following previous Caesarean section. Evidence suggests that the size of the uterine scar and the residual myometrial thickness (RMT) are associated directly with the risk of uterine rupture and risk of dehiscence in subsequent deliveries. Impact of the prelabour and labour Cesarean section on the RMT has not been studied in detail. Objectives: To compare RMT, Caesarean scar defects and to evaluate the elasticity of the Caesarean scar between women who underwent prelabour and labour Caesarean sections. Methods: This was a Cross sectional analytical study. Women who underwent Caesarean section in their first pregnancy were recruited. Sample was stratified to prelabour and labour Caesarean section groups. Transvaginal ultrasound scan was performed six months following the Caesarean section. Dimensions of the uterus, uterine scar defect, RMT and elastosonography of the uterine scar were assessed. Results: A total of 240 postpartum women were analyzed. Uterine niche was detectable in 194 subjects. Prelabour CS group had demonstrated 91.7% (n = 110) scar defects (uterine niche) out of 120 cases and the rate among labour CS group was 70% (n = 84). There was a significant difference in the presence of uterine niche among 2 groups as Prelabour group was found to have more scar defects (p mm (SD 1.2) and 4.99 mm (SD 1.3) respectively and there was no significant difference (t = 0.38, p = 0.71). There was no significant difference between the dimensions of the uterine CS defects of the studied groups. Prelabour CS group had significantly higher Target strain [0.28 vs. 0.24 (t = 2.12, p = 0.04)] and significantly less strain ratio [1.45 vs. 1.55 (t -2.42, p = 0.04)] than labour CS group indicating a better scar in prelabour group. Conclusion: There was no significant difference in RMT and uterine scar defects between prelabour and labour Caesarean section groups. But prelabour Caesarean section scars were less stiff than labour Caesarean section scars. Further studies are warranted to elaborate on the association.展开更多

This is mainly due to convenience and cost. This study was conducted to ascertain the accuracy of measuring axillary temperature with mercury thermometers in preschool children. Methods: Axillary temperature was measured in 250 preschool children using standardized mercury thermometers. Time taken to record the final temperature and its correlates were assessed. Results: Time taken to record the final temperature extended up to six minutes. This duration varied according to age, body mass index and body temperature, but a significant variation was noted only with age. Conclusions: Measuring axillary temperature with mercury thermometers is subjected to error. They need to be replaced with suitable alternatives.展开更多

文摘BACKGROUND In China,the identification rate and treatment rate of mental disorders are low,and there are few surveys on the prevalence of mental disorders among college students using diagnostic tools such as Mini-International Neuropsychiatric Interview(MINI),so the prevalence and treatment of mental disorders among college students are unclear.AIM To estimate prevalence of mental disorders among medical students in Hebei Province,and provide guidance for improving their mental health.METHODS This was a cross-sectional study based on an Internet-based survey.Three levels of medical students in Hebei Province were randomly selected(by cluster sampling)for screening.Using the information network assessment system,the subjects scanned the 2D code with their mobile phones,clicked to sign the informed consent,and answered a scale.A self-designed general status questionnaire was used to collect information about age,gender,ethnicity,grade,and origin of students.The MINI 5.0.was used to investigate mental disorders.Data analysis was performed with SPSS software.Statistically significant findings were determined using a two-tailed P value of 0.05.RESULTS A total of 7117 subjects completed the survey between October 11 and November 7,2021.The estimated prevalence of any mental disorders within 12 mo was 7.4%.Mood disorders were the most common category(4.3%),followed by anxiety disorders(3.9%);15.0%had been to psychological counseling,while only 5.7%had been to a psychiatric consultation,and only 10%had received drug therapy in the past 12 mo.CONCLUSION Although the estimated prevalence of mental disorders in medical students is lower than in the general population,the rate of adequate treatment is low.We determined that improving the mental health of medical students is an urgent matter.
文摘There is an obvious gap in sprint level at home and abroad,and there are different opinions on the reasons.According to the analysis,physical energy and its distribution in each segment are the main factors restricting the sprint performance in China.Different from middle and long-distance running,we must rely on accurate sectional timing technology to master the law of speed-physical energy change in the process of sprint.Each stage is an integral part of the whole dash process,and each part restricts each other.Each stage has a relative best achievement.Simply pursuing the optimal state of segment is not only not helpful to the final result,but also counterproductive.
文摘In steel plants, estimation of the production system characteristic is highly critical to adjust the system parameters for best efficiency. Although the system parameters may be tuned very well, due to the machine and human factors involved in the production line some deficiencies may occur in product. It is important to detect such problems as early as possible. Surface defects and dimensional deviations are the most important quality problems. In this study, it is aimed to develop an approach to measure the dimensions of metal profiles by obtaining images of them. This will be of use in detecting the deviations in dimensions. A platform was introduced to simulate the real-time environment and images were taken from the metal profile using 4 laser light sources. The shape of the material is generated by combining the images taken from different cameras. Real dimensions were obtained by using image processing and mathematical conversion operations on the images. The results obtained with small deviations from the real values showed that this method can be applied in a real-time production line.
文摘The International Healthcare Community recommends that countries do not exceed a 15% rate for cesarean section (CS). Our objective was to determine the prevalence and factors associated with CS at GPHC from July to September 2022. Methods: A cross-sectional study was carried out and data were collected from 1296 mothers, who met the inclusion criteria, through face-to-face interviews after obtaining prior informed consent. We performed descriptive analyses both for the outcome and independent variables. Bivariate and multiple logistic regression were used to identify factors associated with CS with a p-value Results: The prevalence of CS at GPHC was 28.9% (95%CI: 26.5-31.5). Factors associated factors with CS were mothers aged 20 to 34 years (AOR: 1.56, 95%CI: 1.02 - 2.39, P = 0.039);mothers who received more than three minimum wages (AOR: 1.95, 95%CI: 1.29 - 2.97, P = 0.002) and who attended prenatal care at both public and private health facilities (AOR: 2.49, 95% CI: 1.19 - 5.22, P = 0.022). Likewise, the highest Odds of CS were observed in mothers with gestational hypertension (AOR: 2.00, 95%CI: 1.35 - 2.96, P Conclusion: The prevalence of CS is higher than the ideal rate recommended by the International Healthcare Community. More studies are needed to understand the reasons for such high prevalence at GPHC.
文摘Caesarean section is dramatically increased throughout the world in recent years. Rupture of the uterus is a devastating complication in trial of labour following previous Caesarean section. Evidence suggests that the size of the uterine scar and the residual myometrial thickness (RMT) are associated directly with the risk of uterine rupture and risk of dehiscence in subsequent deliveries. Impact of the prelabour and labour Cesarean section on the RMT has not been studied in detail. Objectives: To compare RMT, Caesarean scar defects and to evaluate the elasticity of the Caesarean scar between women who underwent prelabour and labour Caesarean sections. Methods: This was a Cross sectional analytical study. Women who underwent Caesarean section in their first pregnancy were recruited. Sample was stratified to prelabour and labour Caesarean section groups. Transvaginal ultrasound scan was performed six months following the Caesarean section. Dimensions of the uterus, uterine scar defect, RMT and elastosonography of the uterine scar were assessed. Results: A total of 240 postpartum women were analyzed. Uterine niche was detectable in 194 subjects. Prelabour CS group had demonstrated 91.7% (n = 110) scar defects (uterine niche) out of 120 cases and the rate among labour CS group was 70% (n = 84). There was a significant difference in the presence of uterine niche among 2 groups as Prelabour group was found to have more scar defects (p mm (SD 1.2) and 4.99 mm (SD 1.3) respectively and there was no significant difference (t = 0.38, p = 0.71). There was no significant difference between the dimensions of the uterine CS defects of the studied groups. Prelabour CS group had significantly higher Target strain [0.28 vs. 0.24 (t = 2.12, p = 0.04)] and significantly less strain ratio [1.45 vs. 1.55 (t -2.42, p = 0.04)] than labour CS group indicating a better scar in prelabour group. Conclusion: There was no significant difference in RMT and uterine scar defects between prelabour and labour Caesarean section groups. But prelabour Caesarean section scars were less stiff than labour Caesarean section scars. Further studies are warranted to elaborate on the association.

文摘Objective To determine the factors influencing insomnia and construct early insomnia warning tools for rescuers to informbest practices for early screening and intervention.Methods Cluster sampling was used to conduct a cross-sectional survey of 1,133 rescuers from one unit in Beijing,China.Logistic regression modeling and R software were used to analyze insomniarelated factors and construct a PRISM model,respectively.Results The positive rate of insomnia among rescuers was 2.74%.Accounting for participants’age,education,systolic pressure,smoking,per capita family monthly income,psychological resilience,and cognitive emotion regulation,logistic regression analysis revealed that,compared with families with an average monthly income less than 3,000 yuan,the odds ratio(OR)values and the[95%confidence interval(CI)]for participants of the following categories were as follows:average monthly family income greater than 5,000 yuan:2.998(1.307–6.879),smoking:4.124(1.954–8.706),and psychological resilience:0.960(0.933–0.988).The ROC curve area of the PRISM model(AUC)=0.7650,specificity=0.7169,and sensitivity=0.7419.Conclusion Insomnia was related to the participants’per capita family monthly income,smoking habits,and psychological resilience on rescue workers.The PRISM model’s good diagnostic value advises its use to screen rescuer early sleep quality.Further,advisable interventions to optimize sleep quality and battle effectiveness include psychological resilience training and smoking cessation.
文摘Using the CTD data investigated at about 330 stations in the southern Taiwan Strait, the northeastern South China Sea and their adjacent seas in August and September of 1994, this paper anayses the sectional distributions of salinity in 10 selected sections and discusses the possibility of the Kuroshio's intrusion into the northeastern South China Sea and the southern Taiwan Strait. The results show that: as the main stream of Kuroshio passes by the northern Luzon Strait during the survey period, the 'Kuroshio-influenced water' with some hydrological features of the Kuroshio may extend through the Luzon Strait to the sea areas near both the Dongsha Islands and the Taiwan Shoal of the southern Taiwan Strait.

文摘BACKGROUND Epidemiologic studies have explored the association between a single cardiovascular risk factor(CVRF)and resting heart rate(RHR),but the research on the relation of multiple risk factors with RHR remains scarce.This study aimed to explore the associations between CVRFs clustering and the risk of elevated RHR.METHODS In this cross-sectional study,adults aged 35-75 years from 31 provinces were recruited by the China PEACE Million Persons Projects from September 2015 to August 2020.We focused on seven risk factors:hypertension,diabetes mellitus,dyslipidemia,obesity,smoking,alcohol use,and low physical activity.Multivariate logistic regression was used to calculate odds ratios(OR)for elevated RHR(>80 beats/min).RESULTS Among 1,045,405 participants,the mean age was 55.67±9.86 years,and 60.4%of participants were women.The OR(95%CI)for elevated RHR for the groups with 1,2,3,4 and≥5 risk factor were 1.11(1.08-1.13),1.36(1.33-1.39),1.68(1.64-1.72),2.01(1.96-2.07)and 2.58(2.50-2.67),respectively(Ptrend<0.001).The association between the CVRFs clustering number and elevated RHR was much more pronounced in young males than in other age-sex subgroups.Clusters comprising more metabolic risk factors were associated with a higher risk of elevated RHR than those comprising more behavioral risk factors.CONCLUSIONS There was a significant positive association between the CVRFs clustering number and the risk of elevated RHR,particularly in young males.Compared clusters comprising more behavioral risk factors,clusters comprising more metabolic risk factors were associated with a higher risk of elevated RHR.RHR may serve as an indicator of the cumulative effect of multiple risk factors.
文摘Background Comorbidity of irritable bowel syndrome(IBS)and psychiatric disorders is common,and the prevalence of at least one psychiatric disorder has been reported as high as 80%among patients with IBS.Aims To explore the association of anxiety-depressive disorders with IBS and its different subtypes,and to evaluate the associations of lifestyle habits,dietary habits and sleeping quality with IBS.Methods A comparative cross-sectional study was conducted at the AL-Mahsama Family Practice Center,Ismailia,Egypt.It was carried out between October 2019 and October 2020.Participants were categorised into 175 patients with IBS,diagnosed using the Rome IV criteria,and 175 patients without IBS.A semistructured questionnaire was used to collect data on sociodemographic characteristics,lifestyle habits,dietary habits and sleep quality from both groups.The Hamilton Anxiety Rating Scale was used to assess anxiety symptoms,whereas the Beck Depression Inventory Second Edition was used to assess depression symptoms.Results There was a high statistically significant difference between both groups with regard to age,education,occupation and socioeconomic status(SES),being a smoker,being physically inactive,having sleep disturbance and having irregular meals;being either obese or overweight was more reported in the IBS group.There was a high statistically significant difference in the rate of anxiety and depression between patients with and without IBS.Mild,moderate and severe anxiety were reported in 37.1%,42.9%and 20.0%of patients with IBS while most(80.0%)of the patients without IBS reported mild anxiety.Regarding depression,mild,moderate and severe depression were reported in 60.0%,14.3%and 25.7%of the patients with IBS while most(82.9%)of the non-IBS participants reported mild depression.Conclusions The study shows a significant association between anxiety-depressive disorders and IBS,but no significant associations between anxiety-depressive disorders and IBS subtypes.
文摘Background: Measuring axillary temperature with mercury in glass thermometers is continued in clinical practice though there are many limitations. This is mainly due to convenience and cost. This study was conducted to ascertain the accuracy of measuring axillary temperature with mercury thermometers in preschool children. Methods: Axillary temperature was measured in 250 preschool children using standardized mercury thermometers. Time taken to record the final temperature and its correlates were assessed. Results: Time taken to record the final temperature extended up to six minutes. This duration varied according to age, body mass index and body temperature, but a significant variation was noted only with age. Conclusions: Measuring axillary temperature with mercury thermometers is subjected to error. They need to be replaced with suitable alternatives.
