Comprehensive condition monitoring of large industry systems such as nuclear power plants (NPPs) is essential for safety and maintenance. In this study, we developed novel system-scale diagnostic technology based on deep-learning and IR thermography that can efficiently and cost-effectively classify system conditions using compact Raspberry Pi and IR sensors. This diagnostic technology can identify the presence of an abnormality or accident in whole system, and when an accident occurs, the type of accident and the location of the abnormality can be identified in real-time. For technology development, the experiment for the thermal image measurement and performance validation of major components at each accident condition of NPPs was conducted using a thermal-hydraulic integral effect test facility with compact infrared sensor modules. These thermal images were used for training of deep-learning model, convolutional neural networks (CNN), which is effective for image processing. As a result, a proposed novel diagnostic was developed that can perform diagnosis of components, whole system and accident classification using thermal images. The optimal model was derived based on the modern CNN model and performed prompt and accurate condition monitoring of component and whole system diagnosis, and accident classification. This diagnostic technology is expected to be applied to comprehensive condition monitoring of nuclear power plants for safety.

Objective : A new point of view on the chronic back pain proposed which is, named neuropathic back pain[NBP]. Some proposed a certain pain scale as an useful diagnostic tool. Before scientific verification, some doctors prescribed a new anticonvulsant for the NBP. We investigated diagnostic tools for NBP by a review of the literature. Methods : A comprehensive computer search of the English literature concerning neuropathic low back pain was performed using the key words such as neuropathic back pain and diagnosis in the PubMed. Results : In 1998, the term NBP was first used in a patient with lung cancer. In the English literature, there were two diagnostic methods for the NBP, Neuropathic pain scale[NPS] and a pharmacological test. NPS is a pain questionnaire, which depends on the patients' subjective reports on the given questions, such as 'how hot is your pain feel'. By the pharmacological test, NBP was defined as 50% or more decrease of pain on intravenous lidocaine and on local anesthetic epidurally. It also depends on the patients' subjective response to the therapy. Conclusion : There were still no reliable objective diagnostic criteria for the NBP. It seems to be better to reserve the new anticonvulsants for the NBP till scientific approval.

Objectives : The purpose of this guideline is to show the evidence-based guidelines of diagnosis and evaluation of Hwabyung by the synthesis and organization of existing research contents. Methods : We investigated the existing research on the concept of Hwabyung. Further, we investigated the diagnostic tools, self-diagnostic method, symptoms assessment tools, oriental medical diagnostic methods, treatment evaluation tools and other testing methods of Hwabyung. Results : There was a Hwabyung diagnostic interview schedule (HIBDS) in the standardized measure for the diagnosis of Hwabyung. In the symptoms assessment tools of Hwabyung, there was a self-report measurement tool of Hwabyung and measurement tool of Hwabyung to be evaluated by the interviewer. In the oriental medical diagnostic method, there was an instrument of pattern identification for Hwabyung. In the treatment assessment tool, there was an instrument of oriental medical evaluation for Hwabyung. In addition, MMPI, SCL-90R, Zung's self-rating anxiety scale (SAS), Zung's self-rating depression scale (SDS), State-Trait Anger Expression Inventory (STAXI) and etc. can be used for the diagnosis and assessment of Hwabyung. Conclusions : We expect 'Clinical Guidelines for the Treatment of Hwabyung' to be useful for the diagnosis and assessment of Hwabyung.

Purpose: This study was performed to investigate the effect of image enhancement of periapical radiographs according to the diagnostic task. Materials and Methods: Eighty digital intraoral radiographs were obtained from patients and classified into four groups according to the diagnostic tasks of dental caries, periodontal diseases, periapical lesions, and endodontic files. All images were enhanced differently by using five processing techniques. Three radiologists blindly compared the subjective image quality of the original images and the processed images using a 5-point scale. Results: There were significant differences between the image quality of the processed images and that of the original images (P< 0.01) in all the diagnostic task groups. Processing techniques showed significantly different efficacy according to the diagnostic task (P< 0.01). Conclusion: Image enhancement affects the image quality differently depending on the diagnostic task. And the use of optimal parameters is important for each diagnostic task.

Purpose: The Braden Scale is one of the most intensively studied risk assessment scales used in identifying the risk of developing pressure sore. However, not all studies show that the predictive validity of this scale is sufficient. The purpose of this study was to evaluate the Braden Scale for predicting pressure ulcer development. Methods: Articles published 1946 and 2013 from periodicals indexed in Ovid Medline, Embase, CINAHL, KoreaMed, NDSL and other databases were selected, using the following keywords: 'pressure ulcer'. The QUADAS-II was applied to assess the internal validity of the diagnostic studies. Selected studies were analyzed using meta-analysis with MetaDisc 1.4. Results: Thirty-eight diagnostic studies with high methodological quality, involving 17,934 patients, were included. Results of the meta-analysis showed that the pooled sensitivity and specificity of the Braden Scale were 0.74 (95% CI: 0.72-0.76), 0.75 (95% CI: 0.74-0.76) respectively. However the predictive validity of the Braden Scale has limitation because there was high heterogeneity between studies. Conclusion: The Braden Scale's predictive validity of risk for pressure ulcer is interpreted as at a moderate level. However there is a limitation to the interpretation of the results, because of high heterogeneity among the studies.

It is very important to detect and identify small anomalies and component failures for the safe operation of complex and large-scale artifacts such as nuclear power plants. Each diagnostic technique has its own advantages and limitations. These facts inspire us not only to enhance the capability of diagnostic techniques but also to integrate the results of diagnostic subsystems in order to obtain more accurate diagnostic results. The article describes the outline of four diagnostic techniques developed for the condition monitoring of the fast breeder reactor "Monju". The techniques are (1) estimation technique of important state variables based on a physical model of the component, (2) a state identification technique by non-linear discrimination function applying SVM (Support Vector Machine), (3) a diagnostic technique applying WT (Wavelet Transformation) to detect changes in the characteristics of measurement signals, and (4) a state identification technique effectively using past cases. In addition, a hybrid diagnostic system in which a final diagnostic result is given by integrating the results from subsystems is introduced, where two sets of values called confidence values and trust values are used. A technique to determine the trust value is investigated under the condition that the confidence value is determined by each subsystem.
