While emergency operating procedures (EOPs) occupy an important role in the management of various abnormal situations in nuclear power plants (NPPs), current technology for the validation of EOPs still largely depends on manual review. A validation method for EOPs of NPPs is thus proposed based on dynamic multi-level flow modeling (MFM). The MFM modeling procedure and the EOP validation procedure are developed and provided in the paper. Application of the proposed method to EOPs of an actual NPP shows that the proposed method provides an efficient means of validating EOPs. It is also found that the information on state transitions in MFM models during the management of abnormal situations is also useful for further analysis on EOPs including their optimization.

Apical periodontitis is a biofilm-mediated infection. The biofilm protects bacteria from host defenses and increase their resistance to intracanal disinfecting protocols. Understanding the virulence of these endodontic microbiota within biofilm is essential for the development of novel therapeutic procedures for intracanal disinfection. Both the disruption of biofilms and the killing of their bacteria are necessary to effectively treat apical periodontitis. Accordingly, a review of endodontic biofilm types, antimicrobial resistance mechanisms, and current and future therapeutic procedures for endodontic biofilm is provided.

Achilles tendinopathy has seen good results with conservative management. However, the management of Achilles tendinopathy lacks evidence-based support, and tendinopathy patients are at risk of long-term morbidity with unpredictable clinical outcomes. Data suggests that 29% of tendinopathy patients required surgical intervention during the follow-up period. Chronic pain after damage to the Achilles tendon is a result of incomplete recovery of fibrous tissue. Recently, many procedures, including various injection treatments, have been tried without understanding proper preservation techniques and procedures for faster tendon recovery, especially for patients who want to quickly return to their daily lives. This article is an extensive literature review on nonoperative management of Achilles tendinopathy.

Focal enhancement typically suggests local tumor progression (LTP) after renal cell carcinoma is percutaneously ablated. However, evaluating findings that are false positive or negative of LTP is less familiar to radiologists who have little experience with renal ablation. Various imaging features are encountered during and after thermal ablation. Ablation procedures and previous follow-up imaging should be reviewed before determining if there is LTP. Previous studies have focused on detecting the presence or absence of focal enhancement within the ablation zone. Therefore, various diagnostic pitfalls can be experienced using computed tomography or magnetic resonance imaging examinations. This review aimed to assess how to read images during or after ablation procedures, recognize imaging features of LTP and determine factors that influence LTP.

Objective : Radiofrequency (RF) medial branch neurotomy is an effective management of lumbar facet syndrome. However, pain may recur after period of time. When pain recurs, it can be repeated, but the successful outcome and duration of relief from repeated procedures are not clearly known. The objective of this study was to determine the success rate and duration of pain relief from repeated radiofrequency medial branch neurotomy for lumbar facet syndrome. Methods : A retrospective review of medical records was done on 60 consecutive patients, from March of 2006 to February of 2009, who had an initial successful RF neurotomy but subsequently underwent repeated procedures due to recurrence of pain. All procedures were done in carefully selected patients after at least two responsive medial branch nerve blocks. C-arm fluoroscopic guide, impedance, sensory and motor threshold monitoring tools were used for the precise placement of electrodes. Responses of repeated procedures were compared with initial radiofrequency neurotomy for success rates and duration of pain relief. Results : There were 48 females and 12 males. Mean age was 52.4 years (range, 26-83). RF medial branch neurotomy was done on one side in 38 and both sides in 22 patients, each covering at least three segments. Average visual analog scale at last procedure was 6.8. Twelve patients had previous lumbar operations, including 4 patients with instrumentations. Fifty-five patients had two procedures and five patients had three procedures. Mean duration of successful pain relief (> 50% of previous pain for at least 3 months period) after initial radiofrequency neurotomy was 10.9 months (range, 3-28) in 51 (85%) patients. From repeated procedures, successful pain relief was seen in 50 (91%) patients with average duration of 10.2 months (range, 3-24). Five patients had third procedure, which was successful in 4 (80%) patients with mean duration of 9.8 months (range, 5-16). This was not statistically different from initial results. There were no permanent neurological complications from the procedures. Conclusion : Results of this study indicate that the frequency of success and durations of relief from repeated RF medial branch neurotomy for lumbar facet syndrome are similar to initial results that provided relatively prolonged period of pain relief without major side effects Each procedure seems to provide successful pain relief for about 10 months in more than 85% of carefully selected patients when properly done.

Purpose : The establishment of clinical skills centers(CSCs) to facilitate the teaching and assessment of clinical skills is one of the more recent developments occurring in medical schools worldwide. The aim of this study is to review experiences of CSCs in other medical schools and learn how to design a CSC in our school. Methods : This study was undertaken in two steps. In the first step, educational activities of CSCs in 6 medical schools were reviewed. In the second step, a search for articles of journals regarding clinical skills education in CSCs was conducted. Results : The review of CSCs programs reveals variations among centers in teaching and assessment activities. However there are increasing trends of utilizing CSCs in teaching and learning in CSCs. The delivery of clinical skills is expanded by an increasing use of simulated patients and realistic simulators. Through an audio/video technology, availability of more detailed monitoring and feedback. CSCs also provide greater opportunity for assessment of communications skills, physical examination and practical procedures. Conclusions: CSCs contribute to the effectiveness in clinical teaching and assessment. Educational benefits of a CSC can be maximized by utilizing new delivery methods, implementing educational strategies and staff development programmes.

The medical expenses review system in Korea has developed under fee-for-service system with its own unique structure. The importance of reviewing medical expenses has been emphasized, as the size of medical expenditures moving through the health insurance legal context and its weight in the national economy have increased very rapidly. It is, however, analyzed that the feuds and arguments continue among the stakeholders for the lack of laws supporting the medical expenses review system. The medical expenses review is a series of administrative procedures, deciding whether claims from medical care institutions to the insurer are legal and valid or not. It mainly controls the increase of unnecessarily excessive health insurance claim and prevents fraudulent claim and abuse and checks the less use or unsuitable use of medical resources. It also works a function guarantees medical benefits for the appropriate treatment according to the object of health insurance system as a social insurance scheme. The dispute on legal base of the medical expenses review is about the source of law in the medical expenses review. There are the Health Insurance Act and administrative laws as jus scriptum and the guidelines of review as administrative orders. The medical expenses review should reflect various factors, such as the development of medical healthcare technologies, the health expenditures distribution, the financial situation of the health insurance, and the evaluation on the level of appropriate benefits. It is also likely to adapt to the traits of characters of medicine, and trends and transition, Besides it should judge the legality and the validity of medical benefits expenditures by synthesizing these all factors. And the evaluation system of appropriateness of medical benefits was administrative procedure which was consecutive with reviewing the medical expenses system and it was intended to make up for the result of reviewing the medical expenses in more comprehensive levels.
