The investigators conducted this survey to find out prevalence of diseases and symptoms of the 812 nurses who were working at the 12 Seoul city and University's hospital in Seoul by retrospective study The results of survey were summarized as follows: 1. Distribution of Prevalence Rate of Diseases and Symptoms. 1) An average prevalence rate of diseases and Symptoms of the nurses/100 persons was 64.3 cases at Present October I.1972 2) The total number of diseases and Symptoms was 522 cases at present Oct, I 1972 for the survey nurses. The prevalence rate of following diseases/100 persons were as, foot sore-11, 3. myopia-9.7, neuralgia-9.6, anemia-9.1, insomnia-8.6 cases and the corrected number percent of prevalence rate of diseases and symptoms of the above diseases into 100 denominator were as follows : foot sore-17.6% , myopia-15.4%, neuralgia-14.9%, anemia-14.2% insomnia-13.2%. 3) The prevalence rate of diseases and symptoms/100 person for the age group of 45 and over was 140.0 cases and the age of 35-39 years was 27.3 cases. 4) The prevalence rate of diseases and symptoms/100 persons by the rotation system of nurses'duty/day were as follows: two shift system rotation-86.7 cases, three shift system rotation-67.9 cases and day duty only was 56.2 cases, 5) The prevalence rate of diseases and symptoms/100 person by the basic nursing education background seemed to be lower occurrence against to the higher education and it was 94.4 cases at the Technical Nursing High School graduates. 6) The prevalence rate of diseases and symptoms/100 persons by the marital status of the nurses were as follows; single-64.8 cases, married-48, 7 cases, and widowed-28.6 cases. II. Relationship Between working Experience and prevalence of the Disease and symptoms. 1) There were no relationship by statistical test between prevalence of eye disease and experience at the eye ward(p〉0.05), skin disease and experience at the dermatology ward (p〉0.05), foot sore and experience at the operating room (p〉0.05), varicose vein and experience at the operating room (p〉0.05), sore finger and experience at the central supply room (p〉0.05), infectious disease and experience at the isolation ward(p〉0.05). 2) There was significant relationship by statistical test between pulmonary tuberculosis and experience at the tuberculosis ward (p〉0.05) prevalence of pulmonary tuberculosis was five times in experienced group than non experienced group.

Purpose: Anterolateral thigh (ALT) perforator free flap is commonly used because of its various benefits. The author reports important factors of preoperative and perioperative ALT perforator free flap and causes of failure. Methods: 84 patients who were treated with ALT perforator free flap from December 2004 to 2008, and February 2010 to April 2010 were studied. 61 patients were male and 23 were female. The mean age of patients was 51.1. The main cause was neoplasm and the main reconstructive areas were head and neck area. The size of flap was various from $3{\times}4$ to $12{\times}18$ cm. 6 patients received split thickness skin graft at donor site. Preoperative angiography was checked to all patients. Results: Among the 84 patients, partial necrosis of flaps occurred in 4 patients because of atherosclerosis, varicose vein, or inattention of patient, etc. And total flap necrosis in 5 patients because of abnormal vessels of recipient area or delay of operation, etc. One case of serous cyst was found as the complication of donor area. Two cases of skin graft on donor site were done because of suspected muscle compartment syndrome, 4 cases of that because of large flap. Septocutaneous perforators were found in 7 cases. The author couldn't find reliable perforator in 3 cases, ipsilateral anteromedial thigh perforator and contralateral ALT perforator and latissimus dorsi musculocutaneous free flap were done instead of ALT. There was no case which needed reoperation because of the impairment of blood supply, and 3 cases were revised by leech because of the burn injury by a lamp or venous congestion. Conclusion: Although ALT perforator free flap is widely used with its various merits, many factors such as preoperative condition of donor or recipient area, morphology of defect and operating time need to consider to prevent flap necrosis. And operators should need careful technique because septocutaneous perforator is uncommon, and musculocutaneous perforator is common but difficult to dissect.

The purpose of this study was to examine the state of oral prophylaxis practice among dental hygiene students and their awareness of musculoskeletal diseases in an effort to provide some information on how to strengthen education on treatment posture to manage musculoskeletal diseases and how to raise awareness of musculoskeletal diseases. From November 2 to 13, 2016, a self-administered survey was conducted on 653 sophomores, juniors and seniors with an experience of oral prophylaxis practice. SPSS version 20.0 for Windows was employed to analyze the collected data. The findings of the study were as follows: 1. The largest group that accounted for 37.4% responded that the total number of students undergoing oral prophylaxis practice during a semester was four to six. The biggest group that represented 65.4% answered that the required practice time per student was one to fewer than three hours. 76.0% continued to be in the repeated same posture. 2. As for the posture of patients, supine position was most common for the maxillary sinus, which accounted for 82.2%. And semi-upright position was most common for the mandibular sinus, which represented 49.6%. 3. In regard to the burden of oral prophylaxis practice, 33.9% considered the required for the practice appropriate. 42.3% took the repeated long-lasting posture, and 53.5% were under physical pressure. 55.4% suffered from mental pressure and stress. 4. The most dominant musculoskeletal area that they experienced pain after oral prophylaxis practice was neck with 52.5%; waist with 48.2, shoulders/wrists/hands with 45.5, back with 10.3, buttocks with 4.1, elbows with 2.3, legs with 2.1, ankles/feet with 0.8 and knees with 0.6%. 5. Concerning the maintenance of repeated treatment postures and pain experience, the students who continued to be in the repeated same position underwent more pain than the others who didn't on the shoulders(2.92±1.05), in the waist(3.02±1.01), buttocks(1.75±0.92), elbows(1.55±0.79) and ankles/foot(2.52±1.25). The differences were statistically significant(p<.05, p<.01). 6. As to educational experience on treatment posture and musculoskeletal diseases, 88.8% received education on treatment posture; 87.9%, on what position should be taken in times of cooperation; 46.9%, on musculoskeletal diseases; 51.9%, on carpal tunnel syndrome; 42.3%, on varicose vein. The students who replied education on occupational diseases was necessary accounted for 89.6%. 7. The students who experienced treatment posture education were better aware of the causes of musculoskeletal diseases(3.23±3.00), ways for preventing the diseases(3.33±.834) and how to stretch the body(3.63±.858). The differences were statistically significant(p<.05, p<.001). 8. The students who experienced education on occupational diseases heard more about musculoskeletal diseases(3.27±.965), were better cognizant of the causes of the diseases(3.45±.847), were better aware of how to prevent them(3.55±.805) and found themselves to know how to stretch to prevent the diseases (3.73±.826). The differences were statistically significant(p<.001).
