시스템 가시성평가는 복잡한 시스템과 고도의 신뢰성 분야인 In-Vehicle 산업에서 하드웨어 및 소프트웨어간의 융합과 역할 변화에서 시작되었다. 융합의 중심이 기술에서 문화로 자연스럽게 스며드는 형태로 진화하고 있다. 문화의 주변에 기술의 생태적 특징을 반영하기 위해 유니버설미들웨어의 장점인 생명주기모델을 활용하여 시스템의 가시성을 높이고 직관적 판단을 유도하여 혼란 상태를 대비할 수 있다 .본 연구에서는 유니버설미들웨어 기반의 데이터와 서비스모듈을 유기적으로 표준화 및 안정화하여 시스템 가시성 엔진을 시험하고 평가하였다. 이 모듈은 Intelligent Pervasive Cloud 모듈, Memorial Service 모듈, Life Cycler 모듈로 구성하고 현재와 미래의 통신표준과 응용서비스 표준을 비롯한 다양한 요구사항을 반영하였다. Presently, It is required to change convergence the role of hardware system and software technology that promoted trust of In-Vehicle for integrated complex system visibility evaluation. There is possibility for the period system can invoke unpredictable confusing blank state. The blank state systems have ecosystem characteristics that are supplied, maintained and operated through the complex interactions of technology and culture. Using universal middleware can support the life-cycle model and increase the visibility of complex systems and prepare for confusing situations. In this study, based on universal middleware, data and service dynamic standardized modules were evaluated to support stable system visibility platform. The system visibility module consists of Intelligent Pervasive Cloud module, Memorial Service module and Life Cycler connection module. In addition, the analysis results are supported by various network application service standards through platform independent system and architecture.

The cause and pathogenesis of inflammatory bowel disease remain unknown and no definitetherapy exists until now. The present study was conducted to investigate the anti-inflammatory effectsof a herbal preparation (HemoHIM) in colitis induced by 30 mg of trinitrobenzene sulfonic acid (TNBS)in rats. Sprague-Dawley rats were divided into 5 groups. Each group was treated with 1 mg ofHemoHIM/ml of drinking water, 4 mg of HemoHIM/ml of drinking water, 50 mg of HemoHIM/kgof body weight (i.p. once every other day) or 10 mg/kg of HemoHIMof body weight (i.p. onceevery other day) from the next day. After 2 weeks, rats were sacrificed and morphologic featuresof colons were examined. Ulceration, adhesion, thickening and dilatation were noticed in the colonicmucosa after TNBS instillation. Intraperitoneal injection of HemoHIM (50 and 100 mg/kg of bodyweight) showed the anti-inflammatory effect on adhesion, thickening, dilatation, ulceration, and theinhibition effect on damage score by 72.7% and 90.9%, respectively. Histologically, the colon of TNBS-treated rat showed inflammatory cell infiltration by polymorphonuclear cells, multiple erosive lesionsignificant improvement in these symptoms. The results obtained suggest marked anti-inflamatoryactivity of the HemoHIM at the dose levels examined.

이해준,Lee, Hae-Jun 한국정보통신학회 2020 한국정보통신학회논문지 Vol.24 No.6
소형위성 전력분배 및 전송모듈의 설계와 개발과정에서 딥러닝 알고리즘으로 동적 전력자원의 안정성을 평가하였다. 안정성 평가에 따른 요구사항은 소형위성 탑재체인 SAR 레이더의 전력분배모듈과 수요모듈의 전력전송기능을 구성하였다. 전력모듈인 PDM을 구성하는 스위칭 전력부품의 성능확인을 위해 동적신경망을 활용하여 신뢰성을 검증하였다. 신뢰성 검증을 위한 딥러닝 적용대상은 소형위성 본체로부터 공급되는 전력에 대한 탑재체의 전력분배기능이다. 이 기능에 대한 성능확인을 위한 모델링 대상은 출력전압변화추이(Slew Rate Control), 전압오류(Voltage Error), 부하특성(Load Power)이다. 이를 위해 첫째, 모델링으로 Coefficient Structure 영역을 정의하고 PCB모듈을 제작하여 안정성과 신뢰성을 비교 평가하였다. 둘째, 딥러닝 알고리즘으로 Levenberg-Marquare기반의 Two-Way NARX신경망 Sigmoid Transfer를 사용하였다. In the design and development process of Small-Sat power distribution and transmission module, the stability of dynamic resources was evaluated by a deep learning algorithm. The requirements for the stability evaluation consisted of the power distribution function of the power distribution module and demand module to the SAR radar in Small-Sat. To verify the performance of the switching power components constituting the power module PDM, the reliability was verified using a dynamic neural network. The adoption material of deep learning for reliability verification is the power distribution function of the payload to the power supplied from the small satellite main body. Modeling targets for verifying the performance of this function are output voltage (slew rate control), voltage error, and load power characteristics. First, to this end, the Coefficient Structure area was defined by modeling, and PCB modules were fabricated to compare stability and reliability. Second, Levenberg-Marquare based Two-Way NARX neural network Sigmoid Transfer was used as a deep learning algorithm.

The purpose of the study was to investigate the effect of ginseng saponins (panaxadiol, ginsenoside $Rb_1$, $Rb_2$, Rc, Rd) on jejunal crypt survival, endogenous spleen colony formation and apoptosis in jejunal crypt cells of mice irradiated with gamma-ray. ICR mice were given each saponin (i.p. 50 mg/kg of body weight) at 24 hours before irradiation. The radioprotective effects of saponins were compared with the irradiation control respectively. The jejunal crypts were protected by pretreatment with ginsenoside Rc (p<0.05) and Rd (p<0.05). The spleen colony was increased by pretreatment with panaxadiol (p<0.05) and ginsenoside Rd (p<0.05). And the frequency of radiation induced apoptosis was significantly reduced by pretreatment with panaxadiol (p<0.05), ginsenoside Rb2 (p<0.05), Rc (p<0.05) and Rd (p<0.01). These results suggest that ginsenoside Rc, Rd might have a major radioprotective effect.
