        고엽제 피해자에 대한 국가 보상 현황 및 보훈 정책 원리 수정 제안

        정인재,Chung, Injae 한국환경보건학회 2014 한국환경보건학회지 Vol.40 No.2

        Objectives: Agent Orange TCDD has been related to serious diseases among Korean veterans who were exposed to it. Decades after the end of the war, however, its effects are still being debated. The object of this study was to examine various unmet needs raised among Agent Orange exposed veterans and their families and to find grounds of a new welfare policy for providing alternative legislation. Methods: Literatures concerning Agent Orange, TCDD, the associated diseases, compensation for veterans and Supreme Court sentencing were searched using PubMed, ProQuest, press news and relevant homepages. Results: Agent Orange exposed veterans are eligible for various benefits from the government, including disability compensation for diseases associated with exposure. The Ministry of Patriots and Veterans Affairs has classified certain diseases into two categories, Agent Orange sequela diseases and sequela suspect diseases and has provided differential benefits based on separated laws. Big differences exist in benefits to veterans and their families between the two laws. The absence of definite standards to classify the Agent Orange associated diseases was confirmed by recent Supreme Court sentencing which ruled in favor of US manufacturers. Conclusion: It appears that the evidence for cause and effect of Agent Orange related diseases would never be perfect. The results suggest a need to change welfare principles from presumptive or indefinite disease basis to exposure experiences combined with integrated disability evaluation. We propose to extend eligibility by enacting a new law for Agent Orange exposed Korean veterans.

      • 아데노바이러스 유전자치료제의 독성

        정인재(Injae Chung) 환경독성보건학회 2009 환경독성보건학회지 Vol.24 No.1

        Adenoviral vector (AdV) has been the most widely used viral vector for delivering an exogenous therapeutic gene to human. As of this date, more clinical trials utilize recombinant AdV to treat cancer and monogenic inherited disease as well as vaccine applications. However, the number of clinical trials had dropped markedly following the tragic death of a patient ongoing an AdV therapy for the treatment of an ornithine transcarbamylase deficiency (OTCD). This review is an attempt to provide the information on toxicity generated by AdV-mediated gene transfer. It would serve as a sobering reality to researchers and clinicians exploring the use of AdV, as to the complications involved in human application.

        암 유전자 치료제의 개발 현황

        정인재(Injae Chung) 한국독성학회 2003 Toxicological Research Vol.19 No.3

        Medicine is undergoing a revolution in the understanding of the mechanisms through which disease processes develop. The advent of genetics and molecular biology to oncology not only is providing surrogate predictors of therapy response and survival which are forming the basis for selection among established treatment options, but is providing targets for new directions in therapy<br/> as well. Molecular modification of somatic cells for the purposes of protecting the normal cells from the toxicity of cancer chemotherapy, for the sensitization of the tumor cells to therapy and use of conditionally replicating viral vector have been new directions of cancer treatment which have reached the clinical arena. Advances in molecular pharmacology and vector design summarized in this paper may provide solutions to some of the existing problems in the technology of gene transfer therapy.<br/> Continued basic research into the biological basis of human disease, systemic studies of the application of these discoveries to therapy and the improvement of vector for gene delivery all combined may result in advances in this important field of therapy over the next few years.

        초기 해군 항공기 개발 역사

        정인재(Injae Chung),노경우(Kyungwoo Roh) 한국항공우주학회 2018 韓國航空宇宙學會誌 Vol.46 No.3

        본 논문은 해군 항공의 창시자이자 우리 항공의 개척자이신 조경연 선생님의 업적을 기술하였다. 조경연 선생님은 한국전쟁에 중 버려진 미군 항공기의 부품을 활용하여 다수의 수상 정찰기를 개발하였다. 또한 자신의 주도하에 개발된 항공기들을 바탕으로 해군 항공대를 창설하여 초대 대장으로서 우리 영해의 수호에 헌신하였다. 이로써 우리 해군은 스스로 개발한 항공기를 운용하는 항공부대를 갖게 되었다. 이는 대한민국 해군의 영광스러운 쾌거이자 우리 항공역사의 진정한 시발점이다. This paper describes commander Cho`s achievements, who is not only a founder of naval aviation, but also a pioneer of domestic aviation. He developed a number of seaplanes with components taken from US military aircrafts abandoned during Korean war. He eventually established the naval aviation unit with aircraft developed under his leadership, and devoted his life for coast guard as a first commander. Proudly, ROK navy operated the naval aviation unit based on its own developed aircraft. It was a glorious achievement of ROK navy and a beginning milestone of korean aviation history.

        Synchropter 드론의 개념설계 및 비행시험

        정인재(Injae Chung),문정호(Jung-ho Moon) 한국항공우주학회 2020 韓國航空宇宙學會誌 Vol.48 No.12

        Synchropter는 서로 경사진 한 쌍의 회전날개가 동조 교차 회전하는 회전익 항공기의 일종으로 동축반전 헬리콥터와 마찬가지로 꼬리 회전날개를 제거할 수 있어서 효율적이며 간결한 형태의 비행체 구성이 가능하다. 드론 체계로서의 적합성을 검토하기 위하여 소형 Synchropter를 설계, 제작하여 비행시험을 수행하였다. 설계한 Synchropter는 로터 직경이 1.4m이며 중량이 7kg인 소형비행체로서 효율적으로 비행 특성을 확인하기 위하여 상용부품 기반으로 제작하였다. 비행 제어 시스템은 Open Architecture인 Pixhawk를 기반으로 구성하였으며, Sychropter 제어법칙을 PX4 펌웨어에 탑재할 수 있도록 개발하였다. 정성적 비행시험을 통해 Synchropter의 비행 특성을 분석하였으며, 분석 결과, 드론 체계로서의 활용 가능성을 파악할 수 있었다. A synchropter is a type of rotorcraft in which a pair of blades inclined with each other rotates in synchronization. Removing the tail rotor enables an efficient and compact configuration similar to a coaxial-rotor helicopter. This paper describes the design and flight test results of a small synchropter to examine the suitability of a drone system for the army. The synchropter in this paper is a small vehicle with a rotor diameter of 1.4m and a weight of 7kg and was assembled based on commercial parts to examine flight characteristics effectively. The flight control system adopted Pixhawk, which is designed based on an open-architecture. The model-based design technique is applied to develop the control law of the synchropter and a new firmware embedded on the Pixhawk. Through qualitative flight tests, we analyzed the flight characteristics. As a result of the analysis, we confirmed the possibility of application as a drone system of the synchropter.
