강동윤,이재우,박원형,Kang, Dongyoon,Lee, Jeawoo,Park, Wonhyung 한국융합보안학회 2021 융합보안 논문지 Vol.21 No.1
본 연구의 목적은 코로나19 바이러스 유행 시기에 교대근무체계로 운영하는 보안관제센터를 무중단으로 유지하기 위한 연구 이다. 사이버 보안위협에 대응하는 보안관제 시설은 24시간 365일 실시간으로 운영해야 하는 필수 보안시설이며, 보안운영 및 관리적인 부분에서 매우 중요하다. 만약 감염병 유행, 시스템 장애, 물리적 영향 등 보안관제 시설이 폐쇄되거나 영향이 있는 경우 실시간 사이버 보안위협에 대응 할 수 없으며, 보안문제에 치명적이 될 수 있다. 최근 코로나19 바이러스 유행으로 인한 시설 폐쇄, 장마철로 인한 보안시스템 가용성 장애 등 보안관제 시설 운영을 할 수 없는 사례가 확인되고 있으며, 이 외에도 물리적 영향으로 보안관제 시설을 운영 할 수 없는 상황에 대한 대비가 필요하다. 본 논문에서는 보안관제 시설을 다중화 시설로 구성하여 폐쇄되는 상황 발생 시 무중단으로 운영 할 수 있는 방안을 제안한다. The purpose of this study was to keep the Security Control Center, which operates under a shift system, uninterrupted during the COVID-19 virus epidemic. Security facilities responding to cybersecurity threats are essential security facilities that must be operated 24 hours a day, 365 days a day in real time, and are critical to security operations and management. If security facilities such as infectious disease epidemic, system failure, and physical impact are closed or affected, they cannot respond to real-time cyberattacks and can be fatal to security issues. Recently, there have been cases in which security system facilities cannot be operated, such as the closure of facilities due to the COVID-19 virus epidemic and the availability of security systems due to the rainy season, and other cases need to be prepared. In this paper, we propose a plan to configure a security system facility as a multiplexing facility and operate it as an alternative in the event of a closed situation.

The dream is a well-known experience in the routine life. It is the image and thought being occurred during the sleep, and the complex reaction of our mental world to the event of everyday. In particular, there are so many opinions of the reason why people have a dream and this thesis is telling about the physical and pathological changes in the human as one of that various opinions. The aspects of this thesis are often founded in the diverse texts of oriental Medicine, including the Internal Classics(내경), and there were some cases that regarded the dream as diagnostic object and put to clinical uses. These attempts were not only tried out by particular orient thoght, also the ancient Greeks thought that the dream would represent important informations about the health. But, these ideas have been treated lightly by the impacts of the western medicine since the modern age. Straightforwardly, before the psycho-analytics was not development, most of the doctors and scientists regarded the dream as things like dregs of mind. The central operating bodies of the dream are the Spirit(신) and Hon and Beak(혼백), and the Spirit(신) is more essential part between the two.

Purpose: Since drug reaction with eosinophilia and systemic symptom (DRESS) syndrome is very rare and difficult to diagnose, its exact epidemiology is still unknown. If screening tools based on laboratory results or electronic medical records are available, the occurrence of DRESS syndrome can be monitored in real time. Methods: To screen cases with DRESS syndrome, all the results of both eosinophil and alanine transaminase (ALT) level from July 2014 to June 2015 were analyzed by 36 searching conditions for the signal detection of 7 definite DRESS cases among 199,924 patients during the study period. Those searching conditions were diverse combinations of different cutoff levels of eosinophil and ALT with or without nursing records presenting skin symptoms. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value were calculated for individual searching conditions. Results: As cutoff levels of eosinophil and ALT for screening DRESS increased from 3% to 5% and 40 U/L to 300 U/L, respectively, the sensitivity decreased from 100% to 42.9% and the PPV increased from 0.06% to 13.0%. A combination of eosinophil >10% and ALT >300 U/L which had the highest PPV among 36 search conditions could detect DRESS syndrome by sensitivity 42.9% and PPV 13.0%. When nursing records for skin symptoms were added, PPV was augmented to 21.4%. Conclusion: A combination of eosinophil and ALT levels is a useful search condition for the screening of DRESS syndrome. Nursing records can provide an additional increment in PPV. (Allergy Asthma Respir Dis 2018;6:149-154)

Eperisone is a widely used muscle relaxant and believed to be relatively free of adverse drug reactions. However, a rare case of fatal anaphylaxis has been reported in the literature. Poor awareness due to its rarity and combined administration with other drugs are the major hurdles in diagnosing eperisone-induced anaphylaxis. We experienced 3 cases of immediate hypersensitivity reaction occurring after eperisone administration. Case 1, a 63-year-old female, was admitted via the Emergency Department with urticaria, generalized erythroderma, sore throat, chest discomfort, and dyspnea within 1 hour after administration of common cold remedy. Case 2, a 58-year-old male, visited our allergy clinic to detect culprit drugs. He experienced itching, urticaria, hypotension for several hours after administration of the pills for back pain in the last 3 years. Case 3, a 58-year-old male developed urticaria and dyspnea after administration of medication for a headache. He also experienced urticaria and facial edema after administration of the common cold remedy. Among the medications, eperisone hydrochloride was proven as the culprit drug and others were excluded through oral provocation tests. We advised them to avoid eperisone and issued drug safety card. Clinicians should be aware that eperisone hydrochloride is a potential culprit agent of fatal anaphylaxis. (Allergy Asthma Respir Dis 2017;5:228-231)

최근 건강에 대한 관심이 증가하며 다양한 생체정보를 수집할 수 있는 웨어러블 시장이 확대되고 있다. 또한 이러한 생체신호를 통한 원격의료와 헬스케어 서비스가 보편화될 것으로 예상된다. 본 논문에서는 IoT 장비를 통해 수집한 생체신호를 데이터베이스에 저장 및 웹을 통해 실시간 모니터링이 가능한 서비스를 소개한다. 생체 데이터의 수집 및 저장과 실시간 모니터링을 시스템을 구현함으로 다양한 건강관리 진단에 활용될 수 있다. Recently, as interest in health increases, the wearable market that can collect various biometric information is expanding. In addition, telemedicine and healthcare services through these bio-signals are expected to become common. In this paper, we introduce a service that can store bio-signals collected through IoT equipment in a database and monitor them in real time through the web. By implementing a system for collecting and storing biometric data and real-time monitoring, it can be utilized for various health management diagnosis.

강동윤(Dongyoon, Kang),이상웅(Sangwoong, Lee),이재우(Jeawoo, Lee),이용준(Yongjoon, Lee) 한국정보보호학회 2021 情報保護學會誌 Vol.31 No.3
최근 코로나19 바이러스 감염병 유행으로 전 세계 다수 기업에서는 재택근무제도를 도입했다. 재택근무 경험자 중 절반 이상이 보안위협을 경험하였으며, 다수 기업에서는 자산정보를 보호하기 위해 사내 정보보안 강화에 더욱 중요해졌다. 재택근무를 하기 위해 근로자는 주로 가상사설망을 이용하여 업무를 수행한다. 재택근무제도의 활용도가 높아짐에 따라 재택근무 관련 사이버보안 위협은 증가하고 있다. 이러한 사이버 위협이 증가하고 있으며 가상사설망에서의 보안관제는 앞으로 매우 중요하다. 본 연구는 안전한 재택근무를 위해 가상사설망에서 발생하는 사이버위협에 대한 요소를 정리하여 효율적이고 체계적인 가상사설망을 활용한 보안 강화 방안에 대해 연구한다.
e-Nego 시스템 구축에 따른 전자선화증권 활성화에 관한 일고찰

본 논문은 국내 e-Nego 시스템의 상용화를 위해서는 전자선화증권의 활성화 역시 필수적으로 구현되어야 한다는 전제하에 기존의 전자선화증권 운영방식의 비교를 통해 활성화의 장애요인을 알아봄으로써 전자선화증권의 활성화 방안을 도출하는데 그 목적이 있다. 전자선화증권이 활성화되기 위해서는 첫째로 유통성의 확보가 최우선적으로 해결되어야 할 것이며, 둘째는 국내ㆍ외 인프라 확충이 필요하다는 것이다. 셋째는 전자선화증권에 대한 홍보활동 강화 및 전자선화증권 서비스 요금의 현실화가 필요하다. 본 논문은 주로 문헌연구에 치중함으로써 실증적인 분석이 미흡하여 구체적이고 심층적인 연구를 수행하지 못한 한계를 가지고 있다. 향후 e-Nego 시스템의 상용화와 관련한 전자선화증권에 대한 실증분석을 할 필요가 있다. This study aims to derive the way to reinvigorate electronic bill of lading by discussing the problems in reinvigoration by discussing the problems in existing system of electronic bill of lading under the assumption that commercialization of e-Nego system is mandatory for reinvigoration of electronic bill of lading. For the reinvigoration of electronic bill of lading, the first step will be the securement of negotiability, then the second will be the securement of domestic and foreign infrastructure. Third, there should be a greater effort for promotion of electronic bill of landing and setting up realistic service fee. However, this study still has a limitation in that it has insufficiency in empirical study and more detailed research in electronic bill of lading. In further researches, there is a necessity for more detailed empirical study on commercialization of e-Nego system.
