The purpose of accident analysis is to obtain accurate and objective information about the causes of accidents in order to prevent accidents from reoccurring. This study investigated the characteristics and causes of occupational accidents in Korean industry by comparison with those of Japan and U.S.A The results show that there are some characteristics in the accidents of Korean industry; (1)larger companies tend to have lower accident rates than the smaller ones; (2) inexperience is related to high accident rates; (3) 'awkward or sudden movement' and 'caught in and between object' represents the leading accident type; (4) the body sites most vulnerable to injury are the hands and fingers; and (5) 'fractures' is the leading injury type. These findings identified in this study can be used to prevent the industrial accidents.

Calcaneal fractures are quite often seen in patients with axial loading injury. In the tongue-type of calcaneusal fractures or tuberosity avulsion fractures, bone fragments are often superiorly and posteriorly displaced, because of the insertion of the Achilles tendon and pull of the gastroc-soleus complex. The Ddisplaced bone fragment compresses the soft tissues, leading tothat makes skin necrosis. To prevent further soft tissue injury, early recognition of the injury by the emergency physician and immediate orthopedic consultation is needed.

The method to fabricate the cryostat of superconducting cable is extrusion type which is used Aluminum ingot under high temperature such as 45$0^{\circ}C$ and the cryostat is formed above cable core and MLI layer. In this case, it is expected to occur thermal injury in cable core and MLI layer, so it is necessary to study to prevent thermal injury. So in this paper, using simulation on radiation and convection which are accompany with fabricating cryostat, it is suggested to reduce the thermal injury. By measuring simulation temperature and real temperature, it is possible to check the temperature on cable core and MLI layer and using these temperature, it is possible to predict whether thermal injury is occurred or not on cable core and MLI layer.

Objective : This study was designed to investigate the possibility of AR for chronic renal injury. Methods : The author first investigated the expression levels of DNA by inducing of chronic renal injury. Then, the author investigated the effects of AR on chronic renal injury induced by combination treatment with Adriamycin and cisplatin in terms of changes in body weights and renal tissues, urine volume, BUN and creatinine levels, creatinine clearance and histopathological changes in renal tissues. Total expression levels of 546 genes were elevated or lowered by induction of chronic renal injury. Genes of which whose expression levels were elevated by induction of chronic renal injury were related to the PPAR signaling pathway and fatty acid mechanism, etc. Genes of which expression levels were lowered by induction of chronic renal injury were related to the neuroactive ligand-receptor signaling pathway. Results : Oral administration of AR restored renal mass which was reduced by induction of chronic renal injury. AR also restored creatinine clearance and lowered serum BUN level. In histopathological observation, the AR group has a tendency to prevent tissue damages as shown in the chronic renal injury group. Conclusions : AR can be used to treat patients with chronic renal injury although further study will be needed to elucidate the exact mechanisms in the efficacy of AR on chronic renal injury.

The purpose of this study was to investigate the differences in upper and lower strengths and symmetry between upper body injury group, lower body injury group and non-injury group of bowling athletes. The subjects were the upper body injury group (UG), n = 16, the low body injury group (LG), n = 8, the non injury group, [NG], n = 15). The isometric strength of the bowler was measured using Manual Muscle Tester 01165 (Lafayette Instrument Company, USA) and the symmetry index (SI) was calculated. The results were as follow. The symmetry index of hip extension strength and hip external rotation strength was statistically larger in NG than LG (p <.05). The above results suggest that lower body strength and bilateral symmetry was closely related to injuries of the lower body. In order to prevent injury of the bowler, strengthening of lower body strength and symmetrical training are needed.

Occipito-atlanto-axial subluxation is a type of high cervical injury. Misdiagnosis of this instability might cause several complications, including neurologic deficits. A radiologic evaluation must be performed and specific parameters that imply cervical instability must be confirmed. Full understanding of these parameters may prevent not only delayed diagnosis but also unexpected complication. We report a case of delayed detection of a cervical instability and emphasize the role of proper diagnosis.

Purpose: This study was conducted to determine the factors affecting the prevention of needle stick injury. Methods: Data collection was conducted during the period July 15-31, 2013 by a self-administered questionnaire involving 220 nurses working in 7 hospitals. The data was analyzed by SPSS v18 and AMOS v18. Results: Actions by nurses to prevent needle stick injury were directly and indirectly influenced by perceived benefits, attitude toward the behavior, perceived behavioral control, and intention underlying the behavior. Specially, perceived behavioral control is verified to have not only direct influence but also indirect influence on the performance of preventive action through the intention underlying the behavior. Also, perceived benefits indirectly influence the intention toward the behavior and performance of preventive action through attitude toward the behavior and perceived behavioral control. The predictor variables in this model are 52% explicable in terms of intention of prevention action against needle stick injury, and 66% explicable in terms of performance of preventive action. Conclusion: To ensure high performance of preventive action against needle stick injury, constructing not only the solution that inspires the intention toward behavior but also a system that can positively solve and improve obstructive factors in behavioral performance is of primary importance.

Vertebral artery injury is a rare complication of anterior cervical approach. We report two patients who suffered injury to vertebral artery during anterior cervical spine surgery. The mechanism of injury, their operative management, and the subsequent outcome were assessed and relevant literatures reviewed. The awareness of the possibility of vertebral artery injury is most important to prevent and it's occurrence is best avoided by a thorough understanding of the anatomical relationships of the artery, the spinal canal, and the vertebral body and careful use of surgical instruments.

Ischemia/reperfusion-induced myocardial injury is the main cause of acute myocardial infarction. Dendropanax morbifera $L{\acute{e}}veille$ has been used in traditional medicines for the treatment of various diseases such as headache, infectious diseases, and general debility. However, the effect of extract from D. morbifera (EDM) on myocardial ischemic injury is still unknown. In this study, the effects of EDM on neonatal rat cardiomyocytes with hypoxia/reoxygenation (H/R) injury were investigated. The viability of cardiomyocytes with H (30 min)/R (1 h) decreased; however, treatment with EDM significantly inhibited H/R injury-induced cardiomyocyte death. Further, we observed that reactive oxygen species (ROS) generation and intracellular calcium concentration ($Ca^{2+}{_i}$) were significantly reduced in EDM-treated cardiomyocytes compared with that in H/R-injured positive control. In addition, western blotting results showed that EDM attenuated abnormal changes of RyR2 and SERCA2a genes in hypoxic cardiomyocytes. These results suggest that EDM ameliorates ROS generation and $Ca^{2+}{_i}$ homeostasis to prevent dysregulation of calcium regulatory proteins in the heart, thereby exerting cardioprotective effects and reducing hypoxia-induced cardiomyocyte damage, which verifies the potential use of EDM as a new therapeutic agent for the treatment of myocardial ischemic injury.

Purpose: This study was conducted to update the previous evidence-based nursing clinical practice guidelines for pressure injury. Methods: The guideline was revised in 22 steps based on the international standards. Results: The updated nursing practice guideline for pressure injury consisted of four domains and 494 recommendations. The numbers of recommendations in each domain was: 31 hospital policy, 64 assessment, 386 prevention and management, and 13 education. The recommended grade was 10.3% for A, 13.8% for B, and 75.9% for C. Of these, the major revision was done in 40 recommendations (8.1%). A total of 55 recommendations (11.0%) were newly added. 25 recommendations had minor revisions such as changes or additions for some words, and only one recommendation was deleted. Conclusion: The revised nursing practice guidelines for pressure injury are expected to serve as an evidence-based practice guideline for pressure injury in Korea. This guideline will provide healthcare providers, patients, and caregivers with information to help prevent and manage pressure injuries, leading to improving patient outcomes.
