ABSTRACT
Objective To evaluate the current status of radioactive occupational hazards in the construction of some medical institutions in Tianjin, discover existingproblems and deficiencies, and provide a technical basis for radiation protection management. Methods Based on the requirements of relevant regulations and standards, we comprehensivelyevaluated the results of the pre-evaluation and control effect evaluation of 81 radioactive occupational hazards in Tianjin. Results Among the 35 proposed protective measures for pre-evaluation of radiation occupational hazards constructionprojects, the lowest compliance rate is warning signs and personal protective equipment. Among the 46 construction projects of radioactive occupational hazard control evaluation, the pass rate of protective measures was between 73.9% and 100%, with the lowest pass rate for personal protective equipment. Besides, the pass rate of radiation protectionmanagement evaluation was 95.7% ～ 100%, with the lowest pass rate for the protection management system.The initial inspectionpass rateof the equipment quality control acceptancewas 98.6%, while the pass rate was 97.1% for the relevant workplace radiation protection during the initial inspection. Conclusion The pre-evaluation completion rate of radiological occupational hazard evaluation in Tianjin medical institution construction project, unilateral and area of construction room, workplace layout and zoning, ventilation, shielding measures, personal dose management and occupational health inspection all meet the requirements of regulations and standards. However, there are still some deficiencies in the personal protective equipment, warning signs and the radiation protection management system. Therefore, the regulatory department should further strengthen the evaluation of medical institutions, especially the key supervision and management of non-conformities.
ABSTRACT
OBJECTIVE: To analyze the occupational hazard factors and their critical control points in the process of construction of a large-scale construction project.METHODS: The engineering analysis, worksite survey occupational health and occupational hazard factor testing were conducted in a large-scale construction project, and the results were analyzed. RESULTS: During the process of construction of this large-scale construction project, there were many occupational hazard factors such as silicon dust, welding smoke, wood and other dusts, inorganic compounds of manganese, carbon monoxide, carbon dioxide, nitric oxide, ozone, noise, high temperature, hand-transmitted vibration and ultraviolet irradiation, among them, silicon dust and noise were the most common ones. The over standard rates of exposure concentration of short term of total dust and respirable dust in the workplace were 68.2%(15/22) and 40.9%(9/22), and the over standard rates of exposure concentration of time weighted average were 54.5%(12/22) and 13.6%(3/22), respectively. The over standard rates of the noise intensity of area sampling and personal sampling in workplace were 69.2%(45/65) and 61.0%(25/41) respectively. The four hours energy equivalent frequency-weighted acceleration to vibration of three hand-transmitted vibration positions has been detected, and the result has surpassed the occupational exposure limit.The results of other occupational hazard factors such as high temperature, ultraviolet radiation, wood dust, welding smoke, other dust, manganese inorganic compounds, carbon monoxide, carbon dioxide, nitric oxide, nitrogen dioxide, hydrogen sulfide, hydrogen cyanide and ozone all met the occupational exposure limits. CONCLUSION: There are various occupational hazard factors in the process of construction of this large-scale construction project, among them, noise, dust and hand-transmitted vibration are the most prominent hazards.These hazards are the critical control points of this type of construction projects.
ABSTRACT
Objective To formulate the evaluation criteria for micro-appraisal of comprehensive talents and macro-evaluation of projects.Methods A total of 425 articles were included in the meta-analysis of literature review;Delphi's panel that involved 20 experts,2 rounds of questionnaire surveys were conducted to construct indicators for comprehensive evaluation of talent construction projects;AHP was used to calculate the index weight coefficients for each category of indicators.Results The talent construction project evaluation system includes two sub-systems:micro-evaluation of talents and macro-evaluation of projects.Among them,the talent micro-evaluation system,which includes 12 evaluation indicators,carries out assessments in terms of basic qualities,academic accomplishments,and research achievements.the macro-evaluation system of the project,include a total of 15 evaluation indicators,is mainly assessed from the macro level of project operations-project structure,project process,project results.Conclusions From the perspective of the combination of micro (human resources) and macro (projects),to build a universal index for comprehensive evaluation of talent construction projects,both for the evaluation of the project,but also to conduct a comprehensive evaluation of the training object.
ABSTRACT
Objective ] With a view to promoting the development of medical science and biological medicine industry in Suzhou , a serum bank as part of Biobank project was initiated by city hall and led by Suzhou Health Bureau . [ Methods] The construction of the serum bank was concerned with 4 aspects: 1 ) house building , 2 ) equipment purchasing , 3 ) organization construction , and 4 ) the collecting, processing and preservation of blood sample and information . [Results] The work of house, equipment and organization met the demands of the project .We collected 60 980 blood samples , with 367 837 specimens produced and saved .The plan was completed in the predetermined time . [ Conclusion] We achieved the goal in the first term of the project which we promised to the government , and obtained some good experience from both the methods and working mode .However , we found some problems in op-eration which would be the foundation for further and future development .
ABSTRACT
The implementation,operation and maintenance of building have huge impacts on environment and human health,however,the research about quantitative assessment of damage to human health for construction project still does not appear in China.Based on investigation in literatures about five LCA-based environmental impact assessment systems(EIA) systems,this paper concluded and compared the of health damage parts of the systems referred.Finally,some suggestions for establishing assessment systems of damage to human health especially in health damage indicators selection,characterization and weighting were proposed.
