Objective To explore the clinical characteristics such as hypoxemia in silicosis patients with obstructive sleep apnea-hypopnea syndrome（OSAHS）. Methods A retrospective analysis was conducted on 65 cases of silicosis with OSAHS diagnosed by overnight polysomnography（PSG） admitted in Shandong Provincial Hospital of Occupational Disease from January to December 2022. A total of 65 silicosis patients with OSAHS were included in the case group,including three groups：Phase Ⅰ（30 cases）,Phase Ⅱ（15 cases）,and Phase Ⅲ（20 cases）. At the same time,10 simple OSAHS patients who were not exposed to dust were selected as the control group. The clinical statistics analysis on the characteristics of patients in the Ⅰ,Ⅱ and Ⅲ stages of silicosis with OSAHS and the control group were assessed by Epworth sleepiness scale score（ESS）,body mass index（BMI）,apnea-hypopnea index（AHI）,low oxygen saturation of blood（Low SPO₂）,time of sleep with oxygen saturation under 90%（T90）,obstructive apnea index（OAI） and fractional exhaled nitric oxide（FENO）,etc. indexes. Results Compared to the control group,the levels of AHI[（22.03±6.59）times/h] were increased significantly and Low SPO₂[（78.27±9.54）%] decreased significantly in silicosis patients in stage Ⅱ complicated with OSAHS（both P<0.05）,the level of T90[（14.25±8.53）min],hypopnea index[（11.45±5.18）times/h] were increased significantly in silicosis patients in stage Ⅱ,and T90[（17.09±9.05）min] and hypopnea index[（8.85±3.98）times/h] were increased significantly in silicosis patients in stage Ⅲ（all P<0.01）. Compared with stage Ⅰ silicosis,the AHI and T90 in stage Ⅱ and stage Ⅲ of the case group were significantly increased,and the AHI in stage Ⅱ was significantly higher than that in stage Ⅲ patients（all P<0.05）. The OAI and AHI in stage Ⅱ were significantly increased than those in stageⅠ（all P<0.05）. Conclusion The incidence of nocturnal hypoxemia in patients with silicosis combined with obstructive sleep apnea（OSAHS） is higher than that in simple OSAHS patients who are not exposed to dust.

Objective To explore the correlation between the positive coping style,occupational burnout and work engagement of operating room nurses,and the mediating effect of positive coping style between occupational burnout and work engagement. Methods From April to August 2023,380 operating room nurses from 8 grade-A tertiary hospitals in Shaanxi Province were selected by convenience sampling method to conduct questionnaire surveys using general information questionnaire,occupational burnout scale,simple coping style scale and work engagement scale,and the data were analyzed by univariate analysis,correlation analysis and mediating effect test. Results The scores of positive coping,occupational burnout and work engagement of operating room nurses were （23.25±6.34）,（34.96±12.80） and （31.27±10.02）points,respectively. The results of correlation analysis showed that active coping among operating room nurses was negatively correlated with occupational burnout（r=-0.230,P<0.01）,work engagement was positively correlated with positive coping（r=0.418,P<0.01）,and work engagement was negatively correlated with occupational burnout（r=-0.417,P<0.05）. The active coping of operating room nurses played a partial mediating role between occupational burnout and work engagement,accounting for 14.85% of the effect. Conclusion The active coping of operating room nurses plays a partial mediating role between occupational burnout and work engagement. Surgical room nursing managers should pay attention to this mediating effect,actively guide nurses to take proactive measures when facing difficulties and problems,alleviate the fatigue caused by work,and enhance their work engagement.

Objective To evaluate modified glasgow prognostic score（mGPS）,calculated inflammatory markers such as neutrophil/lymphocyte ratio（NLR） and platelet/lymphocyte ratio（PLR） in the diagnosis of coal workers' pneumoconiosis（CWP）,and to provide assistance for the prevention and treatment of CWP. Methods A total of 154 CWP patients and 120 healthy controls from Hunan Prevention and Treatment Institute for Occupational Diseases were collected from January to December 2022. The value of PLR,CAR,NLR and mGPS for predicting the prognosis of CWP were evaluated by receiver operating characteristic curve（ROC） and the correlation between the PLR,NLR,mGPS and lung function indicators of CWP patients were analyzed. Results The levels of leukocytes[（8.20±3.3）×10⁹/L],percentage of neutrophils[（67.85±10.9）%],absolute value of neutrophils[（5.75±3.30）×10⁹/L] and forced vital capacity（77.29±18.49） in patients in CWP Ⅲ group were significantly increased compared with CWP Ⅱ group,Ⅰgroup and control group. In addition,the percentage of lymphocytes[（21.67±9.38）%] and the absolute value of lymphocytes[（1.62±0.70）×10⁹/L] in CWP Ⅲ group were lower than those in the other three groups. Erythrocyte sedimentation rate[（23.43±17.71）mm/h] and C-reactive protein[（12.15±7.12）mg/L] levels in CWP stage Ⅲ group were higher than those in CWPⅠ group,and the differences were statistically significant（both P<0.05）. Compared with the other three groups,the serum concentrations of NLR（5.32±2.64） and PLR（196.01±51.01） concentrations in CWP stage Ⅲ patients were significantly increased（both P<0.05）. Meanwhile,compared with CWPⅠ stage and Ⅱ stage patients,the serum mGPS concentration in CWPⅢ patients was significantly increased（0.81±0.67）（both P<0.05）. There was a negative correlation between PLR,NLR,mGPS and FVC（r=-0.244、-0.197、-0.298,all P<0.05）,Meanwhile, PLR,NLR,mGPS and FEV₁/FVC were negatively correlated（r=-0.300、-0.225、-0.349,all P<0.05）. The areas under the ROC curves of NLR and PLR were 0.767（95%CI：0.698-0.837） and 0.626（95%CI：0.551-0.702）（both P<0.01）. Conclusion PLR,NLR and mGPS can be used as indicators of inflammatory status and severity in clinical prognosis of patients with CWP. NLR is more sensitive to assessing disease activity compared with PLR.

Methods From 2020 to 2022,rice and its growing paddy soil samples were collected from various points in rural areas of a city in northern Jiangsu. The contents of lead（Pb）,cadmium（Cd）,mercury（Hg）,chromium（Cr）,arsenic（As） were detected by atomic absorption spectrophotometry or graphite furnace atomic absorption spectrometry,evaluate the risk level of heavy metal pollution with the methods of the single factor index and Nemerow comprehensive pollution index,and the correlation between the two was analyzed. Results The average content of Pb,Cd,Hg,Cr and As in paddy soil was 0.01,0.05,0.34,and 0.04 mg/kg,respectively,all of which did not exceed the standard. The evaluation result of single factor index showed that the soil was in a pollution-free state,while the comprehensive risk evaluation result of Nemero index showed that the soil in some points was in warning limit state（1.67%）,and the others were in safe state（98.33%）. Mercury was not detected in rice grown in soil. The average content of Pb,Cd, Cr and As in rice was 0.01,0.05,0.34 and 0.04 mg/kg,respectively. Lead in rice was below the limit by the official standards,while the exceed ratio of cadmium,arsenic and mercury in rice were 4.44%,3.89% and 0.006%,respectively. The results of safety evaluation of rice by single factor index showed that 8 sites had mild and severe cadmium exceedances,7 sites had mild arsenic exceedances,and 1 site had mild chromium exceedances. There were significant positive correlation between arsenic in paddy soil and arsenic in rice,lead in paddy soil and lead and arsenic in rice,mercury in paddy soil and mercury and chromium in rice（all P<0.05）. Conclusion The heavy metal environmental quality of paddy soil is generally clean or still clean,and the rice in some areas is polluted by cadmium,arsenic and chromium in varying degrees. The heavy metal contents such as As,Pb,Hg and Cr in rice were correlated with the As,Pb and Hg in the growth soil,so the safety of rice needs attention.

Objective To investigate the current situation and correlation of psychological quality,self-regulation fatigue and sleep quality of medical staff in emergency department of tertiary public hospitals,and to explore the influence of psychological quality and self-regulation fatigue on sleep quality. Methods Convenience sampling method was used to select medical staff in emergency departments of 6 tertiary public hospitals in Mianyang City as the survey objects from June to July 2023. Psychological quality scale,self-regulated fatigue scale and sleep quality scale were used to investigate 247 medical staff in emergency department. Multiple linear regression analysis was used to explore the influencing factors of sleep quality of medical staff in emergency department. Results The Pittsburgh sleep quality index scale（PSQI） score of 247 emergency medical staff was （8.19±4.16）points, of which 158（63.97%） emergency medical staff had a total PSQI score of ≥5 points and had sleep disorders. The score of psychological quality was （285.49±55.92）points. The score of self-regulation fatigue was （45.42±15.54）points. Univariate analysis showed that ages,educational level,job categories,professional titles,length of service in the emergency department,frequency of night shifts（weeks）,average overtime hours,health status,frequency of exercise（weeks/times）,alcohol consumption,and coffee consumption affected the sleep quality of medical staff in the emergency department（all P<0.05）. Correlation analysis showed that the total score of PSQI and the scores of each dimension were negatively correlated with the total score of psychological quality and the scores of each dimension（r=-0.206--0.713,all P<0.05）,ans positively correlated with the total score of self-regulation fatigue and its dimension（r=0.241-0.605,all P<0.05）. Multivariate analysis showed that education level,length of service in emergency department,night shift frequency,health status,alcohol and coffee consumption,psychological quality and self-regulation fatigue were the main influencing factors on the sleep quality of medical staff in emergency department（all P<0.05）,which explained 65.7% of the total variables. Conclusion The sleep quality of medical staff in the emergency department of tertiary public hospitals is poor,among which psychological quality and self-regulation fatigue are important protective factors. Hospital managers should pay attention to the sleep health status of medical staff in special departments,improve their psychological quality and self-regulation fatigue ability,so as to improve their sleep quality.

Objective To evaluate and analyze the changes of nutritional cognition,behavior and dietary nutrition intake of Xinjiang railway workers before and after dietary nutrition intervention by means of questionnaire survey on nutritional knowledge,attitude,behavior and dietary nutrition intake of railway workers,and to evaluate the effects of dietary nutrition intervention,so as to provide reference for guiding railway workers to provide scientific meals and reasonable diets. Methods From May to August 2023,a random sample of 119 males and 96 females aged 18-49 were selected from the canteen and dining staff of a railway station as the research subjects. The nutritional cognition and behavior of railway staff was investigated by dietary nutrition KAP questionnaire,and the dietary nutrient intake of railway staff was investigated by food weighing and accounting method and 24-hour dietary review method. Dietary nutrition intervention for railway workers was carried out by means of dietary nutrition education,and the effects before and after intervention were compared and analyzed. Results The average score of general nutrition knowledge in the questionnaire survey of Xinjiang railway employees were （10.16±1.95）points before intervention and （14.86±0.54）points after intervention,the average score of nutrition attitude were （12.63±3.13）points before intervention and （23.87±0.37）points after intervention,the average scores of nutritional behavior were （29.16±2.95）points before intervention and （41.25±5.64）points after intervention,the average total scores were （59.13±3.54）points before intervention and （84.19±7.42）points after intervention,and the differences before and after intervention were statistically significant（all P<0.05）. Before the dietary nutrition intervention for railway workers,there was an unbalanced food intake,uncoordinated intake ratio of the three productive nutrients,and insufficient intake of most vitamins and minerals. After the intervention,there was a significant improvement in the proportion of nutrient intake in the three major production capacities and vitamins and minerals,reaching the recommended range of the "2013 Chinese Dietary Reference Intake for Residents" and the "2022 Chinese Dietary Guidelines for Residents". Conclusion Railway workers have a high recognition of promoting physical health and improving work efficiency through reasonable dietary nutrition,but at the same time,there are many unreasonable dietary behaviors. Through dietary nutrition intervention,it can obviously enrich the dietary nutrition knowledge of railway workers,improve the dietary nutrition attitude,improve the dietary nutrition behavior,and achieve the goal of reasonable diet and balanced nutrition.

Objective To construct and preliminarily validate an artificial intelligence algorithm to predict the development trend of job burnout in editors of Chinese science and technology journal. Methods A simple random sampling method was used to investigate the job burnout in editors of Chinese science and technology journals based on "questionnaire stars" from March 1 to May 1,2023. Firstly,seven machine learning algorithms,including random forest,simple Bayes,K-nearest neighbor,support vector machine,artificial neural network,logistic regression and gradient enhancement algorithm,were used to construct the prediction model,and then a new fusion model was constructed based on the above seven algorithms by weighted voting method. Finally,receiver operating characteristic（ROC） curve,calibration curve and decision curve were used to evaluate the efficacy of the model, and SHAP value was used to evaluate the importance of predictive variables. The model application software was constructed based on R shinyAPP. Results A total of 341 editors were included in the analysis. The incidence of job burnout was 40.2%（137/341）. The area under the ROC curve of the fusion model was 0.807（95%CI：0.761-0.853）,the sensitivity was 0.774（95%CI：0.709-0.839）,and the specificity was 0.772（95%CI：0.709-0.836）. The calibration curve showed that the fusion model had good calibration（Hosmer-Lemeshow χ²=5.036,P>0.05）. The top five importance of prediction characteristics were personal monthly income level,weekly working hours,weekly overtime,whether there had been honors or rewards in the past year,and whether the division of responsibilities is clear. The decision curve showed that when the prediction probability of job burnout was between 20% and 90%,taking certain intervention measures can achieve maximum benefit. Conclusion A prediction model for the development trend of job burnout in Chinese science and technology journal editors has been preliminarily established based on the artificial intelligence algorithm,which has certain reference value for taking timely measures to alleviate the job burnout of editors.

Methods By the convenience sampling method,the nursing staff from three tertiary hospitals in Beijing City were surveyed from October 2022 to February 2023. A questionnaire survey was conducted using the general information questionnaire,nurse safety behavior scale,job crafting scale,and quality of working life scale. The Mplus 7.0 software was used to construct a structural equation model,to verify the mediating role of nurse safety behavior. Results A total of 475 questionnaires were collected,of which 458 were valid,with a questionnaire effectiveness rate of 96.4%. The scores of safety behavior,job crafting and quality of working life of surveyed nursing staff were （54.95±8.68）,（78.33±10.45） and （182.06±42.15）points,respectively. The job crafting of nursing staff was positively correlated with safety behavior and quality of working life（r=0.370,0.422,both P<0.01）,while the safety behavior of nurses was positively correlated with quality of working life（r=0.589,P<0.01）. The nurses' safety behaviors played a partial mediating role between job crafting and quality of working life,with the mesomeric effect of 0.239,accounting for 32.04% of the total effect. Conclusion The job crafting not only directly predicts the quality of working life of nursing staff from tertiary hospitals in Beijing City,but also indirectly predicts the quality of working life through nurses' safety behavior.

Objective To understand the current situation of senior three students' use of short videos and learning motivation in the urban and rural integration areas of Tianjin under the "double reduction" policy,analyze the relationship between short video use and learning motivation,and provide feasible methods and ways to improve the learning motivation of senior three students in urban and rural combined areas. Methods From May to July 2023,a cluster sampling method was adopted to select 5 high schools in the urban-rural combination areas of Tianjin for questionnaire survey. A self-designed short video usage scale and learning motivation scale were used to analyze and evaluate the level of short video usage and learning motivation among senior three students in the urban-rural combination areas. Multivariate logistic regression was used to explore the influencing factors of short video usage and learning motivation. Results The score for short video usage among 455 senior three students from 5 high schools was （38.18±8.53）points,with an average score of （2.72±0.61）points for each item. The overall score for learning motivation was （59.82±7.29）points,with an average score of （2.30±0.28）points for each item. The content dimension of short video usage was positively correlated with the social orientation dimension of learning motivation（r=0.322,P<0.01）,while the time dimension of short video usage was negatively correlated with the personal achievement dimension of learning motivation（r=0.204,P<0.05）. There was a statistically significant difference in learning motivation among senior three students in urban-rural fringe areas with different family economic statuses（P<0.01）. In this study,the number of people who use the "Douyin" short video APP,choose to open short videos in the "evening",are interested in the "variety" content,pay attention to the "professionalism" of short video bloggers,and influence the "life tips" were the largest,with 241（52.97%）,298（65.49%）,211（46.37%）,357（78.46%）,and 170（37.36%） people,respectively. The number of people who use the "Volcano Video" short video app,choose to open short videos at "midnight",are interested in "learning skills" content,pay attention to the "appearance" of short video bloggers,and influence "star chasing choices" were the least,with 2（0.44%）,19（4.18%）,193（42.42%）,105（23.08%）,and 53（11.65%） people,respectively. Lack of self-discipline,watching short videos at midnight,and having nothing to do in free time were related to students' low learning motivation（OR=1.753,3.824,2.411,all P<0.05）,watching inspirational content,watching content that broadens horizons,watching bloggers with higher professional traits,and watching content with positive and healthy energy were related to students' high learning motivation（OR=0.431,0.540,0.297,0.737,all P<0.05）. Conclusion The learning motivation level of senior three students in the urban and rural combined areas of Tianjin is generally low,and sufficient attention and importance should be given. The relationship between the use of short videos and learning motivation is significant. Schools,families,and students should pay attention to guiding and self-regulation of the use of short videos to improve the learning motivation level of senior three students.

Objective To understand the status quo of interpersonal sensitivity of higher vocational nursing students during internship,and analyze its influencing factors,so as to provide reference for improving the interpersonal communication ability of internship nursing students in higher vocational colleges. Methods Convenience sampling was used from November 2022 to May 2023 to select the higher vocational nursing students who practiced in six hospitals in Anhui Province from Anhui Vocational College of City Management as the research subjects. The general data questionnaire,interpersonal sensitivity measure,positive psychological capital questionnaire and professional identity questionnaire were used to investigate. Multiple linear regression was used to analyze the influencing factors of interpersonal sensitivity of higher vocational nursing interns. Results The total score of interpersonal sensitivity of 112 higher vocational internship nursing students was 73-132 points,with an average score of （106.83±13.81）points. The five dimensions were ranked in descending order according to the average score of the items：interpersonal care[（3.07±0.62）points],need for approval[（2.92±0.44）points],timidity[（2.88±0.41）points],vulnerability[（2.75±0.51）points],and separation anxiety[（1.84±0.39）points]. The correlation analysis results showed that the scores of each dimension and total score of interpersonal sensitivity scale of higher vocational internship nursing students were negatively correlated with the scores of positive psychological capital and professional identity（all P<0.05）. The results of multiple linear regression analysis showed that gender,personality,positive psychological capital and professional identity were the influencing factors of interpersonal sensitivity among higher vocational internship nursing students（all P<0.05）,which could explain 24.7% of the variation. Conclusion The interpersonal sensitivity of higher vocational internship nursing students in Anhui Vocational College of City Management is generally at a medium level,with significant individual differences,which is related to gender,personality,positive psychological capital and professional identity. Nursing educators can formulate targeted intervention measures based on the influencing factors to improve the interpersonal communication ability of higher vocational internship nursing students.

Flight is a highly programmatic process task,and unexpected event refers to an unforeseen or unanticipated situation during flight,including mechanical failures,sudden weather changes,navigation errors,etc. Unexpected events have a significant impact on flight safety and can increase physiological and psychological stress on pilots,affecting their decision-making ability and posing a threat to overall flight safety. This article is based on previous research and reviews the changes in pilots' physiological indicators,negative emotions,and task performance during unexpected events during flight. Unexpected events during flight can affect pilots' physiological indicators,trigger negative emotions,and decrease their task performance. The impact of unexpected events on pilots is modulated by individual differences,learning effects regarding unexpected events,and evaluation factors. Future researchers need to further study and understand the effects of unexpected events on pilots in order to develop more effective strategies to improve flight safety.
