The purpose of this study is to examine which factors determine fall experience among Korean elderly. To achieve this purpose, it uses the Korean Longitudinal Study of Aging(KLoSA), wave 1 and 2. Participants aged 65 from wave 1 were selected. From wave 2, a dependent variable was selected and it was fall experiences since the first interview in 2006. Other than this variable, all independent variables were selected from wave 1. In analyses, x2 or t-test were conducted to examine whether independent variables significantly differ between falls and no falls. Then, since a dependent variable consisted of two categories-falls or no falls, multiple logistic regressions were run. Female, using hearing aid, having two diseases, having three or more diseases, depression, and exercise 5 times/a week or more elevated the odds ratios of fall experience. compared to their reference categories. Particularly, if Korean elderly had three or more diseases or depression, their likelihood of fall experience would have about 2 times higher than their reference categories. In conclusion, health practitioners should make the elderly be recognized how much these risk factors are important to falls. Also, Korean government should support Korean elderly having these risk factors to prevent them from falling.
Ninety patients underwent mitral valvular heart surgery associated with or without aortic valve surgery and subjected to a clinical study in relation to their control of postoperative atrial fibrillation. There were 26 males and 64 females ranged in age from 16 to 56 years with a mean of 35.2 years. Systemic arterial embolizations were observed in 11 patients [12.2%]. Four patients of them were in normal sinus rhythm and 7 in atrial fibrillation. Out of these, left atrial thrombi were found only in 2 at the operation. Intraoperatively confirmed left atrial thrombi were in 16 patients [17.7%] of all 90 patients: Eleven patients occurred at the age of more than 40 years, 14 were in atrial fibrillation and 2 only had previous episodes of systemic arterial embolization. Sixty three patients underwent isolated mitral valve surgery [OMC 28, MVR 35] and 27 patients associated with aortic valve surgery along with mitral valve [OMC+AVR 13, MVR+AVR 14]. Preoperatively, 44 patients [48.9%] were in normal sinus rhythm. Of them, 35 patients [79.5%] revealed normal sinus rhythm thoroughly after operation without any aid of digitalis or quinidine and 5 patients [11.4%] restored normal sinus rhythm with digitalization alone. Other 3 patients converted to normal sinus rhythm with the addition of quinidine, however, in 1 patient who was resistant to quinidine therapy, electrocardioversion was carried out on the postoperative third week showing normal sinus rhythm. Thus, the most atrial fibrillations that occurred for the first time in the postoperative period, were able to reverted to normal sinus rhythm responding well to antiarrhythmic therapy. Preoperatively, 46 patients [51.1%] were in atrial fibrillation. Of them, only 5 patients returned to sinus rhythm after operation without any aid of digitalis or quinidine and other 5 restored normal sinus rhythm with digitalization: namely 2 restored within early postoperative period and 3 after more than 3 months. Eight patients well responded to quinidine therapy showing normal Sinus rhythm. So far, 25 patients have remained in persistent atrial fibrillation on 6 to 36 months follow-up. In view of these, 17 patients [68%] were over 40 years of age, 22[80%] had long duration of symptom over 5 years and 10[40%] have had atrial thrombi before operation. Left atrial dimension were still more than 40mm in 21 patients on follow up M-mode echocardiogram. One month after operation, 87 hospital survivors were improved by at least one functional NYHA class. There were 3 operative deaths [3.3%, bleeding 1, LCOS 2] and 4 late deaths [LCOS 1, valve thrombosis 1, late bleeding 1, fulminant hepatitis 1] during follow-up period. According to our limited experience, we may conclude that better results will be expected with the addition of quinidine therapy judiciously in the cases of postoperative persistent atrial fibrillation who were aged or had longer history of symptom and left atrial thrombi.

Offshore working environments such as ships, offshore oil and gas plants, and offshore wind turbines are isolated and directly exposed to rough seas, which pose high risks of safety accidents. Therefore, all workers in offshore plants should be able to cope with emergency situations and must be qualified according to relevant laws and regulations such as the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW Convention) and Offshore Petroleum Industry Training Organization (OPITO) standards. In particular, marine workers should be able to perform cardiopulmonary resuscitation (CPR) in isolated locations or enclosed and confined spaces such as those in life-boats, life-rafts, rescue-boats, etc. Because the floor material is made of rubber, it may be difficult to perform chest compressions in life-rafts used to escape from emergency situations in ships or offshore plants. Chest compressions performed on life-rafts may reduce the accuracy of CPR and increase fatigue for those providing aid. To measure the accuracy and fatigue of those performing CPR in life-rafts, 15 experimenters with more than five years of experience as first aid instructors were exposed to different CPR environments in a marine safety training center equipped with an artificial wave generator. The results showed that the accuracy of CPR in the classroom was 99.6 %, but that in various life-raft environments was only 84 %. T-verification of the two sites confirmed the reduced accuracy of CPR performed on life-rafts. CPR on life-rafts should be performed in groups of two and with the use of automated chest compression devices.
Purpose : This study examines satisfaction of students at the department of Emergency Medical Technology with clinical practice and relationship between motivation of achievement and satisfaction with clinical practice and aims to provide basic materials contributing to the improvement of clinical practice education.

The purpose of this study was to understand the dental hygienist's perception of dental materials and to understand the safety status of harmful chemicals. The study was conducted from January to February 2015 for 250 dental hygienists working in Gwangju Metropolitan City. as a result, the degree of recognition of MSDS for dental materials was higher with age (P <0.05) and higher in dental hygienist (P <0.001) working at dental hospital. (P <0.001), and the factors affecting the perception of first aid treatment were positively correlated with experience of hazard education (P <0.001). Therefore, by understanding the MSDS awareness of dental materials by dental hygienists and the safety situation in the handling of hazardous chemical substances, we provide basic data for establishing proper recognition of safety in the handling of harmful chemical substances and developing educational programs to prevent accidents.
Purpose: This study is to examine the relationship between safety awareness and safety accident occurrence with elementary school students. Materials and methods: It selected 10 elementary schools under the supervision of Jeonnam Board of Education and sampled 700 students randomly from 2-3 classes in the 5th and the 6th grade. One preliminary survey was conducted to revise and complement the contents and forms of questionnaire with 70 students of a school from Apr. 1 to 6, 2004 and this study was conducted from Apr. 10 to 30, 2004. Total 700 questionnaires were distributed and 681 were collected (97%) and 602 were used for final analysis except 79 lacking responses. Data collected were analyzed with SPSS statistical program. Results: The average score of safety awareness of subjects by area was high as 2.72 points out of a possible 3. Area showing the highest safety awareness was safety from fire. Girl students had higher safety awareness than boy students. The fifth graders had higher safety awareness than the sixth graders. In safety awareness by the number of siblings, single son or single daughter showed the highest safety awareness. 53.2% of the subjects experienced accident for one year, the frequency of accident was mostly once and most of accidents were occurred at school. Accidents for the last year were higher in boy students, the sixth graders. According to relationship between safety awareness and safety accident, group with lower safety awareness in school safety(P < .022), traffic safety(P < .016), fire safety(P < .019), home safety(P < .007) and accident treatment and first aid(P < .003) had higher safety accidents than that with higher safety awareness. Conclusion: Development of safety education program by grade, that of parents safety education program, field experience and practice with students, teachers and parents and various safety education programs should be substantially and repeatedly accomplished for prevention education of safety accidents. In addition, to prevent and cope with safety accidents, safety education should be reflected on normal education, safety education textbook be developed, special safety education teachers be employed for safety education.
The recent development of cardiovascular surgery as well as aortoarteriogaphy has been established excellent operative result with great aid of limb-salvage. However, less consideration or less experience still exists on the regard of vascular accident and vascular disease, as well as vascular surgery in Korea. During the last 13 years, we experienced only two cases of aorto-iliac occlusion,acute and chronic, regardless of having had more than 300 cases of mitral valvotomy and gradual increasing tendency of arteriosclerosis and hypertension in Korea. Therefore it is noteworthy to report the cases in order to promote the consideration for vascular surgery. Case 1; 52 year old female who had 20 years history of mitral stenosis with uricular fibrillation and received medical treatment for recent 1 year in the medical department. 10 days before admission, acute saddle emboli developed and 15 days after the onset, embolectomy through both common femoral arteries on the groin and abdominal approach was made. The progression of emboll to the right popliteal bifurcation was found by arteriography on operating table and retrograde flushing with heparin solution by the polyethylene catheter inserted through posterior tibial artery. The operation was successful, but 9 hours after operation sudden death occurred. Considering this case, first, mitral valvotomy already before might prevent peripheral embolizatlon, secondarily, the more early detection and surgery might also prevent the progression of emboli. Thirdly, although preoperative or postoperatlve heparinization is controversial for mitraI stenosis, heparinization might prevent additional emboli to vital organs in this case Cases 2; 66 year old female who had 4 years history of left hip and calf intermittent claudication and has had rest pain, inability to walk and ischemic necrosis on the the left leg since last 3 months prior to admission to the orthopedic department under the suspicion of herniated disc. Absence of pulsation on the groin and aortography evidenced aortoillac occlusion predominantly on the left side. Thromboendarterectomy was made and the operative result was successful with absence of claudication, healing of ulcer and aortographic patency of occlusive site. This chronic occlusion is considered to result from arteriosclerosis in origin with the evidence of moderate hypertension, x-ray evidence of calcified plaque on the aortic knob and operative finding of palpable plaques.
Outdoor education emphasizes diverse experiences from the internal growth which is expected from the learners, to the ecological and environmental experiences. It is also the needs of this time and reflected in the education system of Korea. However the goal of outdoor education is not well defined and philosophical efforts to clarify it is also not enough. In this respect, we tried to define the goal and investigated professionalism of outdoor education. Specifically, we investigated the professionalism of teachers and instructors of physical education. The goal was investigated in two areas 1) holistic experience and problem solving skill and 2) aiming self-reflective practitioner. The idea was that educators must not aim simple educational efficiencies but have to become self-reflective practitioners through everyday life. The conclusions of this study are firstly, a safety manual is required to avoid possible injuries and to give first aid in an unfortunate occasion, secondly, an education program is required to train outdoor professionals and lastly, outdoor education should not remain in the boundary of formal education but should be included in non-formal education.
By optimizing the radiation protection the collective dose and individual dose could be reduced during YGN #4 $5^{th}$ outage in 2001. The collective doses for the two high radiation jobs decreased to 85% and 65% of expected doses. The proportion of workers with low dose (below 1mSv) exposure increased 4% while the proportion of workers with over 3mSv and 5mSv exposure are decreased to 2%, 1% respectively. But none is exposed over 8mSv for the annual dose. To aid decision of utilizing the robot, cost- benefit analysis was performed and reasonable point was proposed to use the robot. For the first time job, repeated ALARA meeting and mock up training were implemented to set up working procedure by identifying the trouble. To easily set up standard procedure, mockup process was videotaped and reviewed during ALARA meeting. Monitoring is a good approach to chase radiological working condition such as working time, dose rate. behavior of workers, especially for high radiation work. Those data were estimated and adjusted from the stage of work planning to mock up. At the stage of actual work the monitoring data were compared to the estimation and recorded to database. This database will not only be used as a powerful tool for dose optimization at the following outage but also as a guideline to dose constraint set up for optimization for each specific situation.
