Objective To understand the current situation of the quality of life of patients with pneumoconiosis in Shandong Province,and analyze its influencing factors,so as to provide a scientific basis for proposing effective countermeasures for improving the quality of life of patients with pneumoconiosis. Methods From December 2018 to January 2021,a convenient sampling method was used to select 526 patients with pneumoconiosis in six occupational disease prevention and treatment hospitals in five regions of Shandong Province as the research objects.The questionnaire survey on personal basic information and disease situation was conducted by using the self-made questionnaires and 36-item short form health survey（SF-36）.The influencing factors of quality of life were analyzed by multiple linear regression. Results The comprehensive physiological score of quality of life in patients with pneumoconiosis was （160.76±73.54）points,the comprehensive psychological score was （214.14±76.39）points, and the total score was （374.91±135.98）points.The average scores of the eight dimensions from high to low were social function[（68.23±28.60）points],mental health[（61.51±16.64）points],body pain[（59.66±20.75）points],vitality[（52.34±18.99）points],physiological function[（47.21±24.19）points],role emotion[（32.07±12.54）points],general health[（31.03±19.54）points] and role physical[（22.86±17.72）points],which all were lower than the national norms. The multiple linear regression results showed that dyspnea,limited physical activity,economic burden,self-care and family support significantly affected physiological health,while dyspnea,limited physical activity,financial burden,and self-care significantly affected mental health. Conclusions The patients with pneumoconiosis have a low quality of life,especially poor physical health.When intervening in the quality of life management of patients with pneumoconiosis,the impact of the patient's breathing difficulty grading,self-care,economic burden and activity ability should be fully considered.It is necessary to objectively and accurately assess the patient's condition,actively treat pneumoconiosis and coexisting diseases,strengthen disease education,improve patients' cognition,delay the progression of the disease,and improve the quality of life of patients.

Objective To understand the current situation of risk perception and each dimension,somatization,depression and anxiety of back-office and field employees in papermaking and related industries,explore the mediating effects of risk susceptibility perception between back-office and field tasks and anxiety level in employees in papermaking and related industries. Methods From January to March 2022,a total of 818 employees in papermaking industry and related industries serving the papermaking industry were selected in this survey. They were investigated with the self-designed basic information questionnaire,risk perception scale,and three factors of somatization,depression and anxiety in SCL-90 scale. The SPSS 24.0 was used for general data,correlation and difference analysis,and PROCESS 3.4 plug-in in SPSS was used for intermediary effect analysis. Results The total score of risk perception in 818 employees was （17.58±5.64）points,the seriousness score was （6.23±2.65）points,susceptibility score was （4.80±1.71）points,and controllability score was （6.55±2.40） points. The total score of SCL-90 somatization was （2.51±3.84）points,total score of depression was （3.50±5.32）points,total score of anxiety was （2.46±3.77）points. There was a positive correlation between risk susceptibility and back-office and field tasks and anxiety level（r=0.107, 0.260,both P<0.01）. The risk susceptibility played a complete intermediary role between back-office and field tasks and anxiety level,and the mediating effect accounted for 100.00%. Conclusions The risk susceptibility perception score of field employees is higher than that of back-office employees. The risk susceptibility perception can affect the anxiety level of employees,and risk susceptibility perception plays a complete mediating role between back-office and field tasks and anxiety level. The enterprise managers and social support should focus on improving tolerance range of risk susceptibility perception among field employees,to reduce its impact on anxiety level. Moreover,special attention is needed to be paid to the changes in the mental state of field staff upon their return from the field,with more care and assistance to reduce the physical and mental impact from high risk susceptibility perception.

Objective To investigate hand-transmitted vibration（HTV） exposure level and occupational health management status of riveting and grinding workers in aerospace equipment manufacturing industry,so as to provide basis for prevention and control of occupational arm vibration disease（OHAVD） and provide guidance for enterprises to implement occupational health management. Methods From March to September 2022,118 aerospace equipment manufacturing enterprises were investigated,enterprises with riveting and grinding operations were selected as the research objects,the exposure intensity of operators to HTV was tested,occupational hygiene survey was conducted on the job site,and the measurement and investigation results were analyzed. Results Among the 118 aerospace equipment manufacturing enterprises,there were 20 enterprises involved riveting process,of which 2 enterprises tested the strength of HTV,accounting for 10%.The riveting operation mainly occurs in the general assembly and assembly links,involving 156 operators.All workers had self-conscious symptoms of HTV exposure such as hand numbness and hand pain.There were 57 enterprises with grinding process,and 10 enterprises organized to test strength of HTV at grinding operation posts,accounting for 17.5%.Grinding mainly occurs in welding,bonding and other supporting processes,and some in polishing,deburring and other post-treatment processes.619 operators were involved,of which 248 workers self-conscious symptoms of HTV exposure such as hand numbness and hand pain,accounting for 39.7%,and women had significant subjective symptoms. Among the investigated enterprises,only 2 enterprises organized workers exposed to HTV to undergo occupational health examination,and no abnormal results related to occupational exposure were found. The HTV strength measurement results showed that the HTV strength a_hw(4) of workers in riveting workplace ranges from 0.47-33.09 m/s²,and the over-standard rate was 33.3%. The measurement range of HTV strength a_hw(4) of workers in grinding workplace was 0.012-7.64 m/s²,and the over-standard rate was 5.56%. Conclusions HTV is one of the main occupational hazards in riveting and grinding operations of aerospace equipment manufacturing industry,which should be paid attention to by enterprise managers and workers. Enterprises can explore the use of welding instead of riveting process,vibration reduction for grinding equipment design handle,and workers equipped with special vibration isolation gloves to reduce the harm of HTV. The HTV detection rate and occupational health inspection rate in riveting and grinding work sites of aerospace equipment manufacturing industry are low,so the HTV detection rate and occupational health inspection rate of personnel in riveting and grinding work sites should be increased.

Objective To establish a rapid detection method for 16 phthalate esters（PAEs） in ambient air fine particulate matter（PM_2.5） by ultrasonic extraction ultra high performance liquid chromatography-tandem mass spectrometry. Methods The samples were collected onto a quartz filter membrane by a sampler equipped with the PM_2.5 cutting head. By comparing the extraction efficiency of different extraction solutions,selecting the appropriate extraction solution for ultrasonic extraction of the sample,comparing the separation effect and retention time of three chromatographic columns,16 types of PAEs were detected using ultra high performance liquid chromatography tandem mass spectrometry,and quantified using internal standard method to obtain indicators such as linearity and detection limit. An appropriate amount of standard was added to the quartz filter membrane to evaluate the recovery rate and precision of the method. Results The linear range of 16 PAEs compounds was within the range of 0.5 to 200 ng/mL,and all had good linear relationships,with R>0.995 0. Comparing the extraction effects of 50% methanol aqueous solution,50% acetonitrile aqueous solution,methanol and acetonitrile on the samples with the concentration of 10,50,100 μg/L after spiked,the average recovery of standard addition（n=3） was 71.45%-126.8%,51.71%-124.40%,68.62%-210.3% and 84.08%-110.28%. When using acetonitrile solvent for extraction,the recovery rates of three parallel samples were the most stable,and the recovery rates of 16 PAEs were all between 80% and 120%.When using T3 chromatographic column,all 16 PAEs were separated within 15 minutes,and the separation effect was better. The method precision was ≤7.95%,the detection limit was between 0.001 and 0.077 ng/m³,and the recovery rate was 83.8%-117.6%. Using this method,PM_2.5 samples（n=9） collected from the same outdoor sampling point in Shanghai from November to December 2021 at different periods were detected. A total of 7 phthalate ester compounds were detected,of which 5 had a detection rate of 100%,namely dimethyl phthalate（DMP）（0.26-6.39 ng/m³）,diethyl phthalate（DEP）（0.96-2.04 ng/m³）,and diisobutyl phthalate（DiBP）（9.46-63.40 ng/m³）,dibutyl phthalate（DBP）（2.52-44.60 ng/m³） and di-2-ethylhexyl phthalate（DEHP）（6.29-59.40 ng/m³）. Conclusion The spiked recovery rate of this method is stable,the detection limit is low,and the accuracy and sensitivity are high. The pre experimental processing steps are simple and the analysis time is short,which can be used for the detection of phthalate esters in PM_2.5.

Objective To understand the status and influencing factors of sexual knowledge,sexual concept,sexual psychology among military personnel stationed in a certain department of Tibet,so as to provide reference for further sexual health education and intervention of sexual psychology. Methods The self-made and unregistered questionnaire was used to investigate the current situation of 260 officers and soldiers stationed in a certain department of Tibet in May 2020. Results 20.8% of military personnel held that "spermatorrhea can hurt their vitality",5.8% of them believed that "moderate masturbation is still harmful",and about 50.0% of them did not know the correct contraceptive methods. There were statistically significant differences in the sexual knowledge among military personnel with different demographic characteristics. The mastery of sexual knowledge in military personnel who are only child was higher than those of non only child,the mastery of sexual knowledge in military personnel from urban area was higher than that in those from rural area,the mastery of sexual knowledge in married personnel was higher than that in unmarried personnel,the mastery of sexual knowledge in Han nationality personnel was higher than that in those of ethnic minorities,and the mastery of sexual knowledge in military personnel with high school education or above was higher than that in those with junior high school education（χ²=4.396,5.900,18.189,6.806,7.157,all P<0.05）. The sexual concept of military personnel stationed in a certain department of Tibet had its particularity,among which 48.9% maintained that "sex can take place as long as resonance between two lovers",43.5% argued that "premarital sex will be tried if there is an opportunity to serve",and 51.2% believed that "sex and marriage are two different things". 11.2% agreed that "I like to change girl（boy） friends frequently" and 14.7% agreed that "I can have multiple sexual partners at the same time". In terms of sexual psychology,60.0% of military personnel stationed in a certain department of Tibet had a strong desire to communicate with the opposite sex,but 55.4% of them held that they lacked the skills to communicate with the opposite sex of the same age. 3.5% of them liked to see the same sex naked,and 13.8% of them didn't like their own gender. There were 18.1% of the military personnel stationed in Tibet who often doubt that their sexual function has problems,and 10.0% of them who often doubt that their reproductive function has problems. As far as the answer of "I lack communication skills with the opposite sex of the same age" is concerned,the military personnel stationed in Tibet with Han nationality were more than those with minority nationality,the military personnel stationed in Tibet from urban region were more than those from rural region,and the difference was statistically significant（χ²=5.402,17.770,both P<0.05）. The military personnel stationed in Tibet of different education level had a great difference in this answer,but the difference was not statistically significant（χ²=3.603,P>0.05）. There were no statistically significant differences in the answers of "I often doubt that I have sexual function problems" and "I often doubt that I have reproductive function problems" among military personnel stationed in Tibet with different demographic characteristics（P>0.05）. Conclusions There are some problems in sexual knowledge,sexual concept and sexual psychology of military personnel stationed in a certain department of Tibet. It is necessary to strengthen sexual knowledge education and counseling of sexual psychological problems,strengthen gender communication,psychological counseling of marriage and love,and shape correct concept,to ensure ideological stability of officers and soldiers and the smooth completion of defense tasks.

Objective To investigate the current situation of disaster preparedness of medical personnel in Jiangxi Province and analyze the influencing factors,so as to provide theoretical basis for improving disaster preparedness of medical personnel. Methods A self-designed disaster preparedness questionnaire was used to investigate the current situation of disaster preparedness among 2 401 medical personnel from seven cities in Jiangxi Province using a random sampling method in February 2021,and the data were analyzed. Results The disaster preparedness score of 2 401 medical personnel in Jiangxi Province was （220.09±38.98）points, which was above the middle level. The results of univariate analysis showed that there were statistically significant differences in disaster preparedness ability scores and total scores among medical personnel with different marital status（all P<0.05）. There were statistically significant differences in the scores of disaster preparedness knowledge,skills,abilities,and total scores among medical personnel with different working years,types of work units,work departments,whether they have participated in disaster rescue events,whether they have participated in rescue related training,whether they have paid attention to disaster rescue related reports,whether their units have organized relevant training,and whether their families support participating in disaster rescue work（all P<0.05）. There were statistically significant differences in the scores of disaster preparedness skills,ability and total scores among medical personnel whether they are willing to participate in relevant training（all P<0.05）. There were statistically significant differences in the total scores of disaster preparedness among medical personnel whether they are willing to actively participate in medical rescue（all P<0.05）. The multiple linear regression analysis showed that working years,working departments,whether they had participated in disaster rescue events,whether they had participated in disaster rescue related training,whether they paid attention to disaster rescue related reports,whether their units organized relevant training,whether they are willing to take the initiative to participate in training,and whether their families supported participating in disaster rescue work were all influential factors for medical personnel's disaster preparedness（all P<0.05）. The medical personnel who have participated in disaster rescue related training,frequently follow disaster rescue related reports,are willing to actively participate in rescue,have family support to participate in disaster rescue work,and frequently organize relevant training in their units have higher disaster preparedness. The higher the length of service,the lower the disaster preparedness of medical personnel. Conclusion The disaster preparedness of medical personnel in Jiangxi Province needs to be improved,and hospital managers need to strengthen disaster rescue training for medical personnel.

Objective To explore the nursing work pressure and sleep quality of nurses in a grade-A tertiary hospital in Urumqi,analyze the effect of nursing work pressure on sleep quality. Methods From January to May 2022,319 nurses from a grade-A tertiary hospital in Urumqi were selected as the research objects. The general information questionnaire,nurse tress scale（NSS） and Pittsburgh sleep quality index（PSQI） were used to conduct the questionnaire survey,and the data were analyzed. Results The NSS score and PSQI score of 319 nurses in a grade-A tertiary hospital in Urumqi were （92.25±22.81） and （14.23±3.28）points,respectively. There was a significant positive correlation between the total score and each dimension score of NSS and PSQI（P>0.05）,that is,the greater the nursing pressure of nurses,the more serious the sleep problem. The number of children,nursing title,working department,nature of employment and night shift frequency had significant effects on the score of NSS,and the difference was statistically significant（P<0.05）. The nursing work pressure was an important influencing factor of sleep quality,which could explain 31.5% of the variation of sleep quality. Conclusion The higher the level of work stress,the worse the sleep quality of nurses in a grade-A tertiary hospital in Urumqi,and nursing managers should provide psychological and social support to nurses through a variety of strategies to improve their work stress,so as to promote their long-term health outcomes.

Objective To investigate the relationship between the nursing work environment and nurse-assessed quality nursing care and the mediating effect of health-promoting behaviors,so as to provide a reference for managers to formulate targeted measures to improve quality nursing care. Methods In January 2022,a total of 824 nurses from a grade-A tertiary hospital in Beijing and Xi'an were selected as the research objects by convenience sampling,respectively. The nurses' general information questionnaire,nursing work environment scale,health-promoting behaviors scale,and quality nursing care scale were used for the questionnaire investigation. The structural equation model was used to analyze the mediating effect of health-promoting behaviors between the nursing work environment and nurse-assessed quality nursing care. Results The score of the nursing work environment,health-promoting behaviors and nurse-assessed quality nursing care was （3.39±0.51）,（3.13±0.52） and （4.64±0.51） points,respectively. The nursing work environment,health-promoting behaviors,and nurse-assessed quality nursing care were positively correlated（r=0.426-0.642,all P<0.05）. The structural equation model showed that the nursing work environment had a direct positive predictive effect on nurse-assessed quality nursing care（β=0.507,P<0.05）,the health-promoting behaviors had a partial mediating effect on nurse-assessed quality nursing care（β=0.096,P<0.05）,and the mediating effect accounted for 15.9%. Conclusion The nursing managers should build a healthy nursing work environment conducive to the participation of nurses and promote the overall health-promoting behaviors of nurses,especially the participation in hospital affairs and physical activities so that nurses can better provide high-quality nursing services for patients.

Objective To investigate the relationship between the prevalence of allergic rhinitis and the indoor environment of the living room in preschool children in Haikou City. Methods A multi-stage stratified cluster random sampling method was used to select 3 049 preschool children from eight kindergartens in Xiuying District and Longhua District of Haikou City from December 2020 to January 2021,and a questionnaire survey was conducted using the general information questionnaire,the core questionnaire and survey and research questionnaire on building dampness and health of the international study of asthma and allergies in childhood（ISAAC）. Results The prevalence of allergic rhinitis among 3 049 preschool children in Haikou City was 7.15%. The multi-factor logistic regression analysis showed that age（OR=1.272,95%CI：1.100-1.470）,only child（OR=1.547, 95%CI：1.152-2.077）,family history（OR=3.658,95%CI：2.692-4.971）,mildew and water damage on the floor and wall in the one year before pregnancy（OR=1.506,95%CI：1.020-2.221）,newly renovated house when children are aged 0-1 years old（OR=1.712, 95%CI：1.013-2.893）,new furniture within the last 12 months（OR=1.437,95%CI：1.017-2.030）,feeling damp air（OR=1.398, 95%CI：1.044-1.873） were risk factors for rhinitis,and gender（OR=0.669,95%CI：0.499-0.898） was protective factor for allergic rhinitis（P<0.05）. Conclusions The prevalence of allergic rhinitis is higher in preschool children aged 6-7 years old. The prevalence of allergic rhinitis in female preschool children is lower than that in male preschool children,and the prevalence of allergic rhinitis in only child is higher than that in non-only child. The children with a family history of allergic rhinitis are more likely to be affected. The damp air in the indoor environment,mildew and water damage on the floor and wall,and new decoration and new furniture are risk factors for allergic rhinitis in preschool children. The parents should pay attention to the ventilation and cleanliness of children's rooms in daily life,and try to avoid preschool children living in newly renovated houses with new furniture or choose healthy and environmentally friendly materials in the process of decoration and purchase of furniture.

Objective To explore the distribution of strontium mineral springs in Shennongjia Forest Region,provide theoretical basis for further development. Methods In May 2018,on-site visits and review of map data were conducted to determine sampling points,and 415 water samples from eight villages and towns in the forest district were collected from May to December,including surface water,shallow groundwater（natural gushing spring water） and deep groundwater（source water of a mineral water plant）. The strontium content of water samples was determined by atomic absorption spectrometry. Results Except for two water samples,the others were all clear and transparent without visible impurities. The test results showed that 26.63% of water samples contained strontium content ≥0.1 mg/L,and 11.13% of water samples contained strontium content ≥0.2 mg/L,which is mainly distributed in Jiuhu and Hongping Town,roughly east-west direction. There was no statistically significant difference in strontium content between surface water and shallow groundwater（P>0.05）. Conclusions The strontium contents of surface and shallow groundwater in Shennongjia are fall in safe limit. The water samples with high strontium content may be related to geological structures. Shennongjia has the potential to form strontium mineral springs,which needs to be verified by further exploration.

Objective To investigate the current situation of vocational nursing students' sense of professional mission, career adaptability and academic engagement,analyze the relationship among them,and explore the mediating effect of career adaptability on the relationship between sense of professional mission and academic engagement. Methods From April to August 2022,1 175 nursing students in a vocational college in Fujian Province were investigated with the sense of professional mission scale, career adaptability scale and academic engagement scale. The structural equation model was used to verify the mediating effect of career adaptability on the relationship between sense of professional mission and academic engagement. Results The total score of sense of professional mission,career adaptability and academic engagement was （42.94±6.51）,（95.96±11.71） and （89.64±15.83）points,respectively. The univariate analysis showed that the differences were statistically significant in the scores of sense of professional mission,career adaptability and academic engagement among nursing students with different grade,place of origin,only child,family residence,student cadres,reasons for choosing nursing major,and social part?time experience（all P<0.05）. There were statistically significant differences in the scores of sense of professional mission and academic engagement among nursing students whose part?time work is related to their major or not（all P<0.05）. There was statistically significant difference in the score of sense of professional mission among nursing students whose parents have received higher education or not（P<0.05）. The sense of professional mission was positively correlated with career adaptability and academic engagement（r=0.563,0.577,both P<0.01）, and career adaptability was positively correlated with academic engagement（r=0.588,P<0.01）. The career adaptability played a partial mediating role in sense of professional mission and academic engagement,accounting for 40.34% of the total effect. Conclusions The vocational nursing students' sense of professional mission,career adaptability and academic engagement are closely related,and all of them are at a good level. The career adaptability plays a partial mediating role in sense of professional mission and academic engagement. The vocational nursing colleges should focus on strengthening students' career education,enhancing their sense of professional mission,encouraging nursing students to engage in their studies with a more positive attitude,and helping them achieve their expected academic achievements.
