OBJECTIVE:To prepare anhydrous iodine-containing or iodine-free hand-cleaning agents for use at field or water-deficient area.METHODS:An adhesive paste was made with PVA as vehicle and PVP-I as disinfector.Iodine value was taken as parameter of quality control.The adhesive-eliminating test was carried out on Escherichia coli and HBV elimi?nating and skin irritation tests were performed in rabbits.RESULTS:This preparation could eliminate bacteria by its adhesive action and had considerable disinfective action because of the ingredient iodine,however it could not eliminate HBV.No irrita?tion to skin was found.CONCLUSION:The preparation can effectively remove the dust,bacteria and viruses from the hands and is suitable for cleaning hands in conditions of wartime,training and water-deficient area.

The framed storehouse and the open rolling shutter door equipment are designed and manufactured for the infrastructure construction.The multipurpose and moved frame operating platform is designed and manufactured according to the demands of loading and unloading as a whole for part medical equipments.In this way,the shortage of the storehouse space is solved and the usual training and moving become easier.

Objective To study way of unloading and positioning of the new type medical shelter. Methods Through repeated testing and practical application, the ways of "3-lines" is used in the ground precession standardization. The first line is guard line of the left marginal of the shelter, the second is allocation line of the end part of the shelter and the third is front wheel alignment line of the whole unloading vehicles. Based on the lines, vehicles carrying shelters access to the ground in accordance with the order of three channel shelters ahead of five functional shelters. Results The real time of the shelter started is reduced to 35min, much lower than the time designed of 4h. Conclusion The application can be carried out precise positioning and improve the speed of the equipment spread.

OBJECTIVE: To explore the effects of psychological capital on occupational stress of employees in labor-intensive electronic enterprises. METHODS: A total of 1 723 employees in 5 labor-intensive electronic enterprises were selected as study subjects by cluster sampling method. The Psychological Capital Questionnaire and Simple Job Stress Questionnaire were used to investigate their psychological capital and job demand-control( JDC) occupational stress. The effect of psychological capital on occupational stress was analyzed. RESULTS: Total average score of psychological capital of the study subjects was( 4. 4 ± 0. 7). The average scores of self-efficacy,hope,resilience,optimism dimensions were( 4. 3 ± 0. 9),( 4. 5 ± 0. 8),( 4. 5 ± 0. 8) and( 4. 4 ± 0. 7),respectively. The proportions of active,relaxed,nervous and passive occupational stress accounted for 24. 2%,24. 7%,23. 5% and 27. 6% respectively. The detection rate of JDC mode high occupational stress was 68. 7%( 1 184/1 723). The proportion of active occupational stress of the low-psychologicalcapital group was lower( 28. 3% vs 20. 2%,P < 0. 001),the proportion of passive occupational stress was higher( 23. 4% vs 31. 7%,P < 0. 001),the positive rate of JDC high occupational stress was higher( 63. 3% vs 74. 1%,P <0. 01),compared with the high-psychological-capital group. The multivariate logistic analysis showed that the risk of JDC high occupational stress in the low-psychological-capital group was higher than that in the high-psychological-capital group( P < 0. 01),after eliminating the confounding factors such as length of service,education level and personal monthly income. CONCLUSION: The psychological capital of employees in labor-intensive electronics enterprises was associated with the occupational stress of the JDC model. The occupational stress can be reduced by improving the psychological capital of workers.
