무기체계 수명주기관리를 위한 체계지원관리 발전방안 연구
이승상,김무영,이명진,서양우 한국방위산업학회 2022 韓國防衛産業學會誌 Vol.29 No.2
In US, IPS elements under the concept of TLCSM are developed to conduct life cycle management of weapon system. Recently, Department of Defense of Korea also enacted the directive for the Life-cycle management and is introducing life cycle management in earnest. However, the directive implementation plan for IPS development is insufficient. This study focuses on the PSM(Product support management) element among the IPS elements. This is because the PSM is a key element to reinforce connectivity from acquisition phase to operation and sustainment phase, and it is a unique element unlike the other 11 elements of the IPS. We analyze the concepts and activities of the PSM element presented in the directive, and suggest improvement directive by considering domestic applicability and the US case. 미국은 총수명주기체계관리(TLCSM) 개념 하에서 통합체계지원(IPS) 요소를 개발 및 확보하여, 무기체계의 수명주기관리를 수행하고 있다. 최근 한국의 국방부도 총수명주기관리업무훈령을 제정하여 본격적으로 수명주기관리를 도입하고 있다. 하지만 IPS 개발의 구체적인 실행방안에 대해서 구체화가 부족한 실정이다. 본 연구는 IPS 요소 중 ‘체계지원관리’ 요소에 대하여 집중 연구한다. 체계지원관리 요소는 획득-운영유지 단계의 연계성 확보를 위한 핵심 요소로써, IPS의 다른 11개 요소와는 다르게 특수성을 가진 요소이기 때문이다. 훈령에서 제시된 체계지원관리 요소의 개념 및 활동에 대해 분석하고, 미국 사례를 바탕으로 국내 적용성을 판단하여 발전방안을 제안한다.

능동위상배열 안테나 고장 특성을 고려한 신뢰도 분석 방안 연구
이승상,조일훈,이정훈,박연경 한국신뢰성학회 2018 신뢰성응용연구 Vol.18 No.4
Purpose: There is the limit of the existing methods (k of N model) applied in the reliability analysis of the active phased array antenna. In this study, we propose a new analysis methods considering the failure characteristics. Methods: In this study, the fault characteristics of the active phased array antenna are defined and the cases are summarized. And that simulate failure situations in all cases. Results: As a result of simulations, other cases of failure besides the previously defined failure cases occurred. Conclusion: Therefore, the new method is more accurate than the existing method to perform a reliability analysis method considering fault characteristics of active phased array antenna.

대학에서 사용하고 있는 학사행정 시스템은 다양하게 변모하는 국가교육 정책과 대학의 특성에 따라 급속히 변모하고 있다. 4년제 대학과 2,3년제 대학에서 사용하는 학사행정 시스템은 규모의 차이가 있지만 유사한 구조를 가지고 있다. 따라서 국가의 교육정책과 대학 특성에 적당한 표준화된 학사 행정시스템의 개발이 요구되고 있다. 기존의 대학 학사행정 시스템은 상당히 많은 구축비용과 구축시간이 소모되었다. 또한 개발된 시스템이 복잡하여 기기에 따른 호환성이 떨어지고 유지보수 및 새로운 기능을 추가 할 경우 상당히 많은 어려움이 있었다. 이러한 문제를 해결하기 위하여 표준화 되고 필요한 부분의 기능을 확장할 수 있는 확장형 대학 학사행정 eXCampus 시스템을 개발하게 되었다 본 논문에서 개발한 eXCampus 시스템을 활용한다면 더욱 편리하고 표준화된 방법으로 학사행정 시스템을 쉽고 빠르게 구축 할 수 있을 것이라 확신한다. Bachelor Administrative System used in university is to be transformed rapidly depending on the national education policy change in various ways and the nature of the university. At 4-years and 2, 3-years universities"s Bachelor Administrative System has difference scale structure, but use the similar structure. Thus, the appropriate standard Bachelor Administrative System is required according to characteristics of the country"s university education policies and administrative systems. The Conventional University Bachelor Administrative System has a significant amount of construction cost and time was consuming. In addition, maintenance and compatibility are falling, if you want to add new features, complexity of a system developed in accordance with the instrument has many difficulty. In order to solve this problem, we develop the Extension University Bachelor Administrative System which is standardized and can extend the functionality of the necessary parts. If you use the developed eXCampus in this paper, we can assure that quickly and easily more convenient and standardized way to build Bachelor Administrative System.

We investigated the effect of safflower-seed on healing of the open tibial fracture in rats. A total eighty male rats (13 weelts,450-500 g) were divided into two groups and immediately afterfracturing the tibia, normal or 10% safflower-seed diet were giver arbitrarity. This treatment wasgiven for 8 weeks. Five er six rats were killed from each group at t, 3. 5. 7 days and 2, 4, 6, 8 weeksafter fracture. Fracture healing was evaluated by eramining the degree of wound healingmacroscopically, radiographf, bone histomorphonletry and histologfcal examination. After 1, 3, 5, 7days. the wound healiug was accelerated in safflower- seed diet group. Radiography does not reveal thedifference in fracture healing between two groups. After 2 weeks, safflower- seed had aB significant,stiinutatory effect on exterBal callus formation (p <0.05). But after 4, 6,8 weeks, no difference was otserved between normal and safflower-seed diet group in callus size. After 2,4,6 and 8 weeks, the hist☞logical study also revealed that the area of cartilage over the fracture site with bone on each side wasdecreased by endochondral ossification in safflower-seed diet group faster than in normal diet group. loconclusion, safflower- see4 stimulate fracture healing during the initial healing phase by enhancing thecallus formation.

Quinones (menadione, benzoquinone, 및 2,3-dimethoxy-1,4-naphthoquinone)의 혈소판 세포독성
승상애,이무열,이주영,김미정,정진호 한국독성학회 1996 Toxicological Research Vol.12 No.2
Our previous studies demonstrated that quinone (menadione) is cytotoxic to rat platelets. In an attempt to assess the relative contributions of redox cycling and/or arylation in quinone-induced cytotoxicity, we have studied three quinones with different mechanisms: 2, 3-dimethoxy-1, 4-naphthoquinone (DMNQ; pure redox cycler), menadione (both redox cycler and arylator), and 1, 4-benzoquinone (pure arylator). The order of redox cycling capacity in platelet rich plasma (PRP) isolated from rats was menadione>DMNQ>1, 4-benzoquonone, which was consistent with the previous studies using isolated hepatocytes. 1, 4-Benzoquinone was more toxic to rat platelets than menadione, while DMNQ did not cause cell death at all. Lactate dehydrogenase inhibition studies revealed that 1, 4-benzoquinone inhibited significantly in a time-dependent manner, while menadione and DMNQ did not at all. These results suggested that arylation by quinone compounds might play a critical role in quinone-induced cytotoxicity in rat platelets.
