ABSTRACT
OBJECTIVE: To explore the association of workplace loneliness, job burnout and conscientiousness in teachers of special education. METHODS: A total of 344 teachers of special education from Guangxi Zhuang Autonomous Region were selected as study subjects by judgment sampling method. The questionnaires of Workplace Loneliness Scale, Maslach Burnout Inventory and Conscientiousness Scale of Big Five Inventory were used to conduct the survey. The mediating role of job burnout in workplace loneliness and conscientiousness was analyzed. RESULTS: The total score of workplace loneliness was 32.6±8.3. The median total score of job burnout and conscientiousness was 31.0 and 30.6 respectively. Partial correlation analysis showed that the dimensions of job burnout were positively correlated with the total score of workplace loneliness and all its dimension scores, and negatively correlated with conscientiousness score(P<0.01). The degree of explanation for the change of workplace loneliness and job burnout on conscientiousness were 9.0% and 17.0% respectively. CONCLUSION: Job burnout plays a partial mediating role in workplace loneliness and conscientiousness in teachers of special education. Reducing workplace loneliness and job burnout can help improve the conscientiousness of teachers of special education.
ABSTRACT
OBJECTIVE: To explore the relationship among loneliness at workplace, job burnout, and turnover intention in prison policemen. METHODS: A convenience sampling method was used to select a total of 290 prison policemen officers as the study subjects in Guangxi Zhuang Autonomous Region. The Workplace Loneliness Scale, Job Burnout Scale and Turnover Intention Scale were used to investigate the loneliness at workplace, job burnout and turnover intention respectively.RESULTS: The scores of turnover intention of 31-40 age group were higher than that of 41 or over age group(P<0.01). The scores of turnover intention in the length of service 1-5 years group and 6-10 year length of service group were higher than that of length of service over 16 years or more(P<0.05). The scores of turnover intention of section group policemen were higher than that of division group(P<0.05). The loneliness in the workplace was positively correlated with job burnout[Spearman rank correlation coefficient(r_S)=0.343, P<0.01], and turnover intention(r_S=0.392, P<0.01), and job burnout was positively correlated with turnover intention(r_S=0.408, P<0.01). Job burnout was the intermediate variable between loneliness in the workplace and turnover intention with a mediating effect rate of 60.2%. CONCLUSION: The job burnout of prison policemen plays a partial role in mediating the influence of loneliness at workplace on turnover intention.
ABSTRACT
Objective To investigate the clinical pathological features and imaging findings of primary pulmonary sarcomatoid carcinoma. Methods Fifteen patients with a pathologically verified primary pulmonary sarcomatoid carcinoma were reviewed retrospectively. Fourteen patients had CT examinations and I0 of them had contrast-enhanced CT scan. Nine patients had chest plain films. Results Of 15 patients, 14 were peripheral and 1 was central, diameters ranging from 2.5 cm to 9.5 cm. Five located in the upper, 3 in the middle and 4 in the lower lobe of the right lung. The other 3 located in the upper left lobe. All cases presented with a spheroid solid lung mass on chest plain film and CT examinations. Three had irregular eccentric cavities. Six were well demarcated, 2 were ill defined, 4 were lobulated and 3 were speculated. The central case had obstructive pneumonia and showed ill defined. Ten showed irregular peripheral heterogeneous contrast enhancement. The center part of the tumor showed no enhancement or inhomogeneous enhancement. Seven had thoracic wall or pleural invasion, 4 had hilar or mediastinal lymphopathy and 2 had metastasis. Histopathologically, 8 were pleomorphic carcinoma, 2 were spindle cell carcinoma, 3 were giant cell carcinoma and 3 were pulmonary blastomas. Conclusion The X-ray and CT findings of the primary pulmonary sarcomatoid carcinoma are not specific. The clinicopathologic features were the evidence of diagnosis.
ABSTRACT
14 aged patients received radiofrequency current ablation(RFCA)to treat drug-refractory tachycardia. The success rate was 97%(13/14).In conjunction with the charcteristicaof aged patients often with long clinical history and apt to be complicated,the paper especially discussed the distinctive feature of application of RFCA to aged patients.
