The Diagnostic and Statistical Manual 4th edition (DSM-IV) has been widely accepted and used for international classification of mental disorder. The DSM has been changed to improve diagnostic reliability and validity through descriptive and categorical approaches which was undertaken atheoretically. The authors reviewed current studies about the DSM-IV classification system and the diagnostic issues of representative categories of anxiety disorder. The authors concluded that the anxiety disorder classification system in DSM-IV has limitations such as a lack of empirical consideration for overlapping features of anxiety disorders and a lack of discriminant validity. To improve diagnostic validity and revise the current DSM-IV classification system, the authors suggested 1) more longitudinal studies for collecting empirical evidence, 2) decreasing the dependence upon operational criteria, 3) deceasing diagnostic boundary blurring, 4) developing disease specific biological diagnostic techniques and 5) continued collaboration between the DSM and International Classification of Diseases (ICD) systems.

Background: Since 2013, the number of requests for diagnosis for horses based on neurological symptoms has increased rapidly in South Korea. The affected horses have commonly exhibited symptoms of acute seasonal hindlimb ataxia. A previous study from 2015-2016 identified Setaria digitata as the causative agent. Objectives: This study is an epidemiological investigation to find out risk factors related to the rapid increase in hindlimb ataxia of horses due to aberrant parasites in South Korea. Methods: An epidemiological investigation was conducted on 155 cohabiting horses in 41 horse ranches where the disease occurred. The surrounding environment was investigated at the disease-causing horse ranches (n = 41) and 20, randomly selected, non-infected ranches. Results: Hindlimb ataxia was confirmed in nine cohabiting horses; this was presumed to be caused by ectopic parasitism. Environments that mosquitoes inhabit, such as paddy fields within 2 km and less than 0.5 km from a river, had the greatest association with disease occurrence. Conclusions: Most horse ranches in South Korea are situated in favorable environments for mosquitoes. Moreover, the number of mosquitoes in the country has increased since 2013 due to climate change. Additional research is required; however, these data show that it is necessary to establish guidelines for the use of anthelmintic agents based on local factors in South Korea and disinfection of the environment to prevent disease outbreaks.

본 논문에서는 ADHD 진단을 해주는 전문가시스템을 설계 및 구현한다. DSM-IV-TR을 이용하여 ADHD 진단기준을 연령대에 따라 단어를 바꾸어 구체화한다. 이 진단지를 가지고 오브젝트와 해당 값을 설정하고 규칙을 생성한다. 그리고 'ADHD 진단 시스템 엔진'과 '사용자 질의응답 프로그램'으로 구성된 진단시스템을 설계한다. 'ADHD 진단 시스템 엔진'은 규칙 기반 추론 엔진으로 Prolog 언어로 구현하여, INPUT을 '사용자 질의응답 프로그램'으로부터 받는다. INPUT에 의해 규칙은 ADHD 진단기준을 기반으로 점화되며 진단결과를 추론해서 OUTPUT을 다시 '사용자 질의응답 프로그램'으로 보낸다. '사용자 질의응답 프로그램'은 Python 언어로 구현하여 사용자와의 대화를 처리하는 인터페이스 역할을 한다. 'ADHD 진단 시스템 엔진'과 '사용자 질의응답 프로그램'의 중간다리 역할을 Pyswip 라이브러리를 통해서 수행한다. 결과적으로 ADHD 진단 전문가시스템을 통해 진단비용 절감과 간편한 이용으로 치료계획에 도움을 주고자한다.

Objective: "Diagnostic yield," also referred to as the detection rate, is a parameter positioned between diagnostic accuracy and diagnosis-related patient outcomes in research studies that assess diagnostic tests. Unfamiliarity with the term may lead to incorrect usage and delivery of information. Herein, we evaluate the level of proper use of the term "diagnostic yield" and its related parameters in articles published in Radiology and Korean Journal of Radiology (KJR). Materials and Methods: Potentially relevant articles published since 2012 in these journals were identified using MEDLINE and PubMed Central databases. The initial search yielded 239 articles. We evaluated whether the correct definition and study setting of "diagnostic yield" or "detection rate" were used and whether the articles also reported companion parameters for false-positive results. We calculated the proportion of articles that correctly used these parameters and evaluated whether the proportion increased with time (2012-2016 vs. 2017-2022). Results: Among 39 eligible articles (19 from Radiology and 20 from KJR), 17 (43.6%; 11 from Radiology and 6 from KJR) correctly defined "diagnostic yield" or "detection rate." The remaining 22 articles used "diagnostic yield" or "detection rate" with incorrect meanings such as "diagnostic performance" or "sensitivity." The proportion of correctly used diagnostic terms was higher in the studies published in Radiology than in those published in KJR (57.9% vs. 30.0%). The proportion improved with time in Radiology (33.3% vs. 80.0%), whereas no improvement was observed in KJR over time (33.3% vs. 27.3%). The proportion of studies reporting companion parameters was similar between journals (72.7% vs. 66.7%), and no considerable improvement was observed over time. Conclusion: Overall, a minority of articles accurately used "diagnostic yield" or "detection rate." Incorrect usage of the terms was more frequent without improvement over time in KJR than in Radiology. Therefore, improvements are required in the use and reporting of these parameters.

Power transformers are an important factor for power transmission and cause fatal losses if faults occur. Various diagnostic methods have been applied to predict the failure and to identify the cause of the failure. Typical diagnostic methods include the IEC diagnostic method, the Duval diagnostic method, the Rogers diagnostic method, and the Doernenburg diagnostic method using the ratio of the main gas. However, each diagnostic method has a disadvantage in that it can't diagnose the state of the power transformer unless the gas ratio is within the defined range. In order to solve these problems, we propose a diagnosis method using ELM based intelligent algorithm and fuzzy membership function. The final diagnosis is performed by multiplying the result of diagnosis in the four diagnostic methods (IEC, Duval, Rogers, and Doernenburg) by the fuzzy membership values. To show its effectiveness, the proposed fault diagnostic system has been intensively tested with the dissolved gases acquired from various power transformers.

진단용방사선발생장치를 이용한 검사는 영상의학과에서 인체 내 정보를 파악하기 위한 가장 유용한 진단장비 중 하나로 신뢰도가 매우 높다. 이와 같은 이유로, 최근에는 영상의학과 영역의 진단 검사 장비를 이용한 검사 건수가 매년 증가하고 있다. 또한, 검사 건수 증가는 장치의 빠른 노화를 불러일으키고 이로 인해 장치에 대한 정도관리(quality control, QC)의 중요성이 대두된다. 특히, 진단용방사선발생장치를 이용한 검사에서 정도관리란 검사시작부터 검사가 끝날 때 까지 발생할 수 있는 모든 문제점을 사전에 알아내고 대처하여 신뢰가 확보된 영상을 획득하여 제공하는 과정에 있는 일련의 모든 활동을 의미한다. 이에 본 연구에서는 진단용방사선발생장치를 이용한 검사에서 정도관리에 대해보고 한다.

This paper describes a fatal case of pneumonia in a 14-day-old dog caused by extraintestinal pathogenic Escherichia coli (ExPEC). The necropsy showed that almost all of left lobes of the lungs had dark-red consolidation. A histopathology examination revealed moderate acute fibrino-hemorrhagic necrotizing pneumonia with intralesional bacterial colonies. Non-suppurative epicarditis, congestion in the liver, and necrosis in the white pulp of the spleen also were found. E. coli with cytotoxic necrotizing factor 1 and α-hemolysin was isolated from the lung. This case was confirmed to have fatal pneumonia caused by ExPEC that led to a systemic infection.
