  • Artificial intelligence application in digital health care has been increasing with its development of artificial intelligence. The convergence of the healthcare industry and information and communication technology makes the diagnosis of diseases more simple and comprehensible. From the perspective of medical services, its practice as an initial test and a reference indicator may become widely applicable. Therefore, analyzing the factors that are the basis for existing diagnosis protocols also helps suggest directions using artificial intelligence beyond previous regression and statistical analyses. This paper conducts essential diagnostic prediction learning based on the analysis of blood cancer factors reported previously. Blood cancer diagnosis predictions based on artificial intelligence contribute to successfully achieve more than 90% accuracy and validation of blood cancer factors as an alternative auxiliary approach.

  • Polioencephalomalacia (PEM) is a neurologic disease of ruminants diagnosed by pathological approach. There is very little information available to understand bovine PEM in Korea. In this study, we investigated the diagnostic rate and pathological features of PEM in 334 necropsied cases of cattle submitted to the Animal and Plant Quarantine Agency in Korea from 2015~2017. PEM was diagnosed only in 13 (3.9%) Hanwoo, the Korean native cattle, and sporadically occurred in our country. The disease was the most diagnosed in fall season, and the age of the cows ranged from 1 month to 3 year. In all PEM cases, softening, and yellow discoloration of the gray matter in the cerebrum and fluorescence at the sites using ultraviolet illumination were grossly observed. Microscopically abundance of glial cells with vacuolar large cytoplasm and neuronal necrosis were commonly observed. This study suggests that future studies are necessary to identify the cause and pathogenesis for the control of PEM in our country.

  • This study deals with the application of knowledge-engineering and a methodology for the assessment & measurement of reliability, availability, maintainability, and safety of industrial systems using fault-tree representation. A fuzzy methodology for fault-tree evaluation seems to be an alternative solution to overcome the drawbacks of the conventional approach(insufficient information concerning the relative frequences of hazard events). To improve the quality of results, the membership functions must be approximated based on heuristic considerations. The purpose of this Is to describe the knowlwdge engineering approach, directed to integrate the various sources of knowledge involved in a FTA.

  • Intestinal duplication is a rare congenital anomaly. The diagnostic approach is difficult because of the differences in its location and clinical presentation. To evaluate the diagnostic as well as the therapeutic approaches in children, the medical records of 20 patients with intestinal duplications which had been operated upon from July 1980 to October 2002 were analyzed, retrospectively. The range of age was from 1 day to 11 years. The variables, such as age, sex, clinical presentation, diagnostic method, localization, anatomic type, treatment, complication, and combined anomalies were analyzed. Most of the cases were presented as incidental finding. The majority of the duplications except hindgut were cystic type. Treatment included segmental intestinal resection, excision of the lesion without intestinal resection, and septotomy. Seventy-five percent of the patients were detected before 1 year of age. The anatomic type of the lesion was closely related with its location. The cases of hindgut were almost always tubular type except 1 case. Clinical presentation was related to age, location, and anatomic type. There were no specific diagnostic methods. Perfect localization and application of appropriate operation are the most important requirements for successful treatment.

  • Tegumental and excretory-secretory proteins are reported as diagnostic antigens for human opisthorchiasis. Rhophilin associated tail protein1-like (OvROPN1L) protein of Opisthorchis viverrini sperm tail showed potential as a diagnostic antigen. The OvROPN1L recombinant fragments were assayed for diagnostic antigenicity for human opisthorchiasis using indirect ELISA. The strongest antigenic region was a N-terminus peptide of M1 - P56. One synthetic peptide (P1, L3-Q13) of this region showed the highest antigenicity to opisthorchiasis. Sera from other parasitic infections including Strongyloides stercoralis, hookworm, Taenia spp, minute intestinal flukes, Paragonimus spp showed lower reactivity to P1. Peptide P1 is located in the disordered N-terminus of ROPN1L supporting its suitability as linear epitope. In the Platyhelminthes the N-terminal sequence of ROPN1L is diverging with taxonomic distance further suggesting that peptide P1 has potential as diagnostic tool in the genus Opisthorchis/Clonorchis. It should be further evaluated in combination with peptides derived from other O. viverrini antigens to increase its diagnostic power.

  • 본 아키텍처(IDPS)는 현 해군 수상함 전투체계의 함정별 소프트웨어 진단 도구를 통합하여 진단 방식의 일관성과 효율성, 진단 소요 시간의 감소를 달성하기 위한 웹기반의 플랫폼을 구축하는 구조적 방법이다. 함형 별 구분된 독립적인 진단 방식으로 인하여 수명주기지원(LTS) 시 인력 운용 측면의 비효율성과 진단자의 숙련도 등에 따른 진단 품질의 차이가 발생하기 때문에, 함정 SW 상태를 진단하는 방식을 함형에 구분없이 일원화하고 진단자에 따른 진단 결과의 편향과 오차가 발생하지 않도록 진단데이터를 플랫폼에 내재된 상태결정알고리즘(SDA)에 의해 판정하도록 지능화하였다. 장기적으로 수상함 전투체계 소프트웨어의 진단에 있어 진단 품질의 하락없는 사람 개입이 최소화된 지능화된 시스템 구축을 추구하며, 이를 통해 진단 소요 시간을 단축하고 진단 결과의 활용에 더 많은 자원을 투입할 수 있을 것으로 기대된다.

  • 슬개대퇴 불안정성의 진단은 정확한 해부학적 지식을 바탕으로 역동적인(dynamic) 기전을 이해하여야 한다. 슬개골의 저명한 탈구는 쉽게 진단되지만, 경미한 외상으로 슬개골이 탈구되어 정복된 후에는 올바른 진찰(dynamic study)없이 방사선 검사(static study)으로 진단을 놓치는 경우가 많다. 그러므로 병력, 이학적 진찰, 방사선 검사, CT, MRI 그리고 관절경 검사까지 다양하게 필요할 수 있다.
