[Survey the relationship between delegation and job satisfaction in nurses]

Introduction: In recent years, numerous organizations have been engaged in increase of job satisfaction, staff empowerment process and partnership in decision making. The aim of this study was to determine correlation between delegation and job satisfaction in nurses

Materials and methods: In this descriptive-correlation study, all nurses of Isfahan Dr Ali Shariati hospital participated in the study samples. Delegation and job satisfaction were the main variables of study. Data were collected by demographic questionnaire, Rowntree Delegation Checklist and Kendall and Hulin Job Satisfaction Questionnaire. Internal consistencies of the instruments were approved 0/70 for Rowntree Delegation Checklist and 0/80 for Kendall Hulin Job Satisfaction Questionnaire. Data were analyzed by SPSS 17 software using Independent student T test and Spearman test

Findings: From 102 nurses, who participated in this study, 53/9% were woman and 46/1% were male. Result indicated that there was no significant correlation between delegation and job satisfaction [r= -0/022 p= 0/826]

Conclusion: The result of the study showed that delegation might not be an effective management tool for job satisfaction improvement in nursing staff. However, more studies are suggested for future

[ rare case report of the Thyroidea Ima and the thymic arteries common trunk, arising from the brachiocephalic artery]

The Thyroidea Ima artery [The artery of Neubauer], was recognized and described by Neubauer in 1786. This artery which was described in the all anatomical textbooks may arise from the arch of aorta, brachiocephalic trunk or other arteries in the upper mediastina. It is considered as a compensatory artery when the other thyroidal vessels showed deficiencies. This artery showed greatly variation in size and gave some anastomotic branches to the thymic artery. The thymic artery arised from the anterior mediastinal branch of the internal thoracic artery but, may also arise from the brachiocephalic trunk, arch of aorta, common carotid or the main trunk of the internal thoracic artery. Its origin from the thyroidea ima is rare. This rare case was seen in a 65 years old male cadaver, the common trunk of the thyroida ima and the thymic arteries originated from the brachiocephalic artery. After a short course it divided into two branches: an ascending [thyroida ima] and descending [thymic] branches. The thyroidea ima artery turned to left and upward to the lower border of the isthmus of thyroid gland. At this point it sent a branch to the lower part of the left lobe of the thyroid which penetrated it deeply and ended in the left inferior parathyroid gland. The main branch continued its course upward to the upper border of the thyroidal isthmus and divided into right and left branches. Each of these branches, after sending a great anastomotic branch to the superior thyroidal artery of their own side, terminated as several small branches in the upper part of the right and left lobes of the thyroid gland. The thymic artery continued its course downward for about three centimeters and ended as two branches in the right and left lobes of thymus. The thyroid gland of this cadaver was larger than the normal ones and the thymus was also clearly noticeable with right and left bobs. According to the embryonic origin and the developmental processes of the inferior parathyroid glands and the Thymus from the neighboring pharyngeal pouches, their blood supply from a common trunk will be acceptable especially when these two glands show some degree of enlargement as shown in this case. In the cases of thyroidectomies, when a surgeon is going to resect an enlarged thyroid gland, the presence of thyroidea ima artery and its branches to the lower part of lobes of thyroid gland would be a useful guidance to identify the inferior parathyroid glands an save them for the prevention of the next hypocalcemia

[ effect of a disaster nursing education program on nurses' preparedness for responding to probable natural disasters]

Nurses, as the pioneers of healthcare in societies, play an important role before, during, and after disasters. Enhancement of their professional skills for the purpose of helping the injured is one of the basic principles in health management in accidents and disasters. The aim of this study is to investigate the effects of a disaster nursing education program on the improvement of nurses' preparedness. It was a quasi-experimental, single group study. The sample including 113 nurses working in Razi psychiatric hospital were selected by census and asked to fill out the "preparedness for confronting disasters" questionnaire, which was developed by the authors. The preparedness program, which consisted of a one-day workshop on disaster management, top-table maneuver, and an operational maneuver, were performed for the participants. The preparedness of all participating nurses was measured one week and also one month after the program. Data were analyzed ANOVA for repeated measures by SPSS-PC [v.17]. Our results showed that the mean scores of knowledge, attitude, and performance improved from 5.55 to 19.88, from 66.18 to 72.41, and from 3.36 to 12.48, respectively in pretest and follow up measurements, which indicated a statistically significant difference [p<0.001]. In addition, the mean score for total preparedness was increased from 75.14 in pretest to 104.77 in follow up, which is statistically significant [p<0.001]. According to the findings in order to promote and maintain the preparedness of nursing staff, inclusion of disaster programs in their academic educational curriculum and as a continued educational program is recommended
