이태희,김진만,한영환,Lee Tae-Hee,Kim Jin-Man,Han Yeong-Hwan 한국미생물학회 2006 미생물학회지 Vol.42 No.2

Clavicorona pyxidata DGUM 29005의 균사 생육을 위한 최적 배양조건 및 효소 활성을 조사하였다. 균사 생육을 위한 최적 온도 및 pH는 각각 $24^{\circ}C$ 및 5.0이었다. 사용된 복합배지 중 malt extract medium (MEM)에서 가장 좋은 균사 생육을 나타내었다. 최소배지로 Czapek-Dox 한천배지를 사용하고 탄소원으로 trehalose, mannitol, sucrose 및 maltose 첨가시 균사생육이 우수하였다. 전반적으로 무기질소원이 유기질소원 보다 균사 생육을 더 촉진하였으며, 무기질소원으로 calcium nitrate를 사용하였을 때 균사 생육이 가장 우수하였다. 인산원으로 $Na_2HPO_4$를 사용했을 때 균사생육이 촉진되었으며, 가장 우수한 비타민원은 p-aminobenzoic acid이었다. MEM 액체배지를 사용하여 $24^{\circ}C$에서 20일간 C. pyxidata DGUM 29005를 배양하여 균사외 분비효소 및 균사내 효소의 활성도를 측정한 결과, 균사외 분비 효소 중 laccase의 활성도가 다른 효소에 비해 높았으며, ${\alpha}$-amylase, chitinase, lipase 및 pretense의 활성도는 낮거나 없었다. The culture conditions for the enhanced mycelial of Clavicorona pyxidata DGUM 29005 were investigated. The optimal temperature and pH for the mycelial growth were $24^{\circ}C$ and 5.0, respectively. It was shown that trehalose was the best supplement of carbon sources in Czapek-Dox medium as a minimal medium for enhanced mycelial growth. In general, inorganic nitrogen sources were better than organic ones for mycelial growth. Calcium nitrate was the best out of the inorganic nitrogen test. The appropriate phosphorous and vitamin were $Na_2HPO_4$ and p-aminobenzoic acid, respectively. After the mycelial of C. pyxidata DGUM 29005 was cultivated at $24^{\circ}C$ for 20 days in MEM broth(pH 5.0), the specific activities of both exomycelial and endomycelial enzymes were determined. Among the exomycelial enzyme assayed, the specific activity of laccase was much higher than those of other enzymes. However, little or no enzyme activities of ${\alpha}$-amylase, chitinase, lipase and pretense were found.

Purpose: To report a case of peripheral ulcerative keratitis and scleritis in a patient with pustular psoriasis. Case summary: A 62-year-old male presented with skin lesions on the hands and feet and pain in the right eye, which started a few days prior. Corrected visual acuity was 0.5 in the right eye and 0.7 in the left eye at initial visit. Corneal edema, erosion, ulcer and peripheral corneal infiltration of the right eye were observed. However, anterior chamber reaction was not observed. Histological analysis of hand skin lesions indicated pustular psoriasis. The patient was initially treated with topical antibiotics and a combined therapy of oral and topical steroids for ocular symptoms. As a result, the right eye showed slight improvement and the oral steroid was discontinued. One month after the initial visit, scleritis appeared on the left eye and topical and oral steroids were restarted for both eyes. Two months after the initial visit, ocular symptoms were improved significantly and corrected visual acuity was 1.0 in both eyes. The mild peripheral corneal opacity remained in the right eye, but the previous inflammations in both eyes were improved. Conclusions: As shown in this case, possibility of peripheral corneal infiltration, corneal ulcer and scleritis should be considered in patients with pustular psoriasis and topical and systemic steroids should be administered if accompanying ocular manifestations occur.

Objective: We made the genital organs inflammatory mice model by vaginal injection of Lipopolysaccharide(LPS), and we intended to make study about anti-inflammatory effects of Gangyeong-Tang, among oral and rectal medication and Herbal-Acupuncture treatment. Method: The female ICR(20-30g) mice were used, the temperature was controlled within $22{\pm}0.5^{\circ}C$ and water and food was not limited. The environment was manipulated to simulate 12 hours of day and 12 hours of night. After LPS injection into vagina, we confirmed on-set of inflammation. 2 days before LPS injection, we started to medicate Gangyeong-Tang in Oral and Rectal and Aqua-acupucture treatment. After 3days from LPS injection, we mesured the White Blood Cell(WBC), Interrleukin-6(IL-6), Tumor Necrosis Factor-${\alpha}$(TNF-${\alpha}$) in blood which was collected from the Retro-orbital Plexus. Results: 1. We made the genital organs inflammatory mice model by vaginal injection of LPS successfully. 2. The number of WBC was decreased significantly as we medicated Gangyeong- Tang in Oral 1g/kg dose, 3g/kg dose and Rectal 1g/kg dose, rectal 3g/kg dose. 3. The concentration of IL-6 was decreased significantly as we medicated Gangyeong-Tang in all group of the Oral, Rectal, Herbal-Acupuncture treatment. 4. The concentration of TNF-${\alpha}$ was decreased significantly as we medicated Gangyeong-Tang in Oral 3g/kg dose and Rectal 1g/kg dose, Rectal 3g/kg dose group. Herbal-Acupuncture treatment group datas showed reductive tendency. Conclusion: As a result of this experiment, we made the genital organs inflammatory mice model by vaginal injection of LPS successfully and demonstrated anti-inflammatory effect of Gangyeong-Tang.

본 논문에서는 대학원가계산 수행시 책임단위를 이익중심점으로 인식하기 위해 이전가격을 어떻게 계산해야 하는가를 분석하였다. 이는 선행연구들이 내부거래를 고려하지 않은 상태에서 대학원가계산의 책임단위를 원가중심점으로 파악했기 때문에 발생하는 문제를 완화시켜 준다는 의의가 있다. 뿐만 아니라 이와 같은 접근방식은 책임단위의 개념을 단과대학, 학부, 학과, 전공에서 교수, 과목까지 확대시킬 수 있다는 장점이 있다. 본 논문에서는 이전가격을 실제 학생의 시간당 등록금 수입으로 계산하는 근거를 제시하고, 이를 바탕으로 책임단위들의 내부거래수입이 어떻게 계산되는지를 설명하였으며, 책임단위의 대상ㆍ구분표시 등과 같이 실무적으로 대학원가를 산정할 때 발생하는 이슈들을 정리하여 처리방식과 이론적 근거를 제시하였다. Prior studies have looked at individual colleges, schools, departments as cost centers for cost accounting purposes for universities. and not as profit centers. The present study purports to find ways of obtaining transfer prices when these units are perceived as profit centers and not as cost centers. The advantages of such approach are manyfold. Taking account of inter-unit transactions and being able to compute profits at the very end department and individual level are most prominent features, among many others, of such approach. Specifically, the study provides bases for using a student's actual tuition per hour amount as the transfer price and shows how the transfer price is used in measuring profits of each unit of interest. The paper also gives some answers regarding inter-unit transactions, segregation of disclosures, and potential incentive problems thereof. All of these issues are appropriately explained using simple numerical examples consitent with the model developed by K-University.

전경 객체의 3차원 복원 정밀도 향상 기법 분석

박지찬(Jichan Park),반유석(Yuseok Ban) 한국정보통신학회 2023 한국정보통신학회논문지 Vol.27 No.4

딥러닝 기술의 발전으로 2차원 영상으로부터 3차원 정보를 정밀하게 생성함으로써 높은 품질의 3차원 복원을 수행하는 기술이 발전하고 있다. 3차원 복원 기술이 일반적으로 갖는 느린 학습 속도의 단점을 개선하기 위해 다양한 연구가 진행되고 있다. 또한, 전경의 3차원 복원 정밀도를 향상시키기 위한 연구가 다양하게 시도되고 있다. 본 논문에서는 배경 영역을 제거하여 전경 영역만을 분리했을 때의 3차원 복원을 세분하여 정량적 및 정성적으로 비교·분석하였다. 실험 결과를 토대로 충분한 외관 특징이 확보 가능한 전경에 대해서 전경을 분리하여 학습하는 것과 학습 영상이 부족한 환경에 대해서 전경 영역을 선택적으로 학습하는 것이 효과적임을 확인했다. Due to the rapid advancement of deep learning techniques, high-quality 3D reconstruction methods that generate precise 3D information from 2D images have been proposed. However, the long duration for model learning has been a major drawback of 3D reconstruction techniques, and many studies have been conducted to address this issue. In addition, there are many ongoing studies to enhance the precision of the 3D reconstruction for a foreground object. This paper conducts quantitative and qualitative comparisons and analyzes the 3D restoration of an object while matting the foreground areas but excluding the background areas from participating in the learning process. Based on experimental results, it has been noted that it is effective to separate foreground objects with sufficient visual features from background areas and to selectively train the foreground information in the condition of insufficient training data.

최근 우리 생활에 로봇 시스템이 빠르게 확산되고 있으며, 로봇의 기능성에 대한 사용자의 요구가 증대됨으로써, 로봇 소프트웨어 컴포넌트는 세분화 되고 더욱 복잡하게 되었다. 따라서 표준화된 소프트웨어 플랫폼의 채택이 불가피하게 되었다. OPRoS는 로봇 시스템을 위한 컴포넌트 기반의 개방 표준 소프트웨어 플랫폼으로 소프트웨어 컴포넌트가 개발되면, OPRoS 표준 규격을 따르는 로봇 소프트웨어 컴포넌트의 적합성 검증이 필수적이다. 본 논문에서는 사용자들에 의해 개발된 각 컴포넌트의 적합성을 검증하는 구조적 적합성 테스트 도구에 대한 설계와 구현에 대하여 다룬다. 일부 실험적 테스트의 결과로서 컴포넌트가 표준 요구를 수용하는지, 수용하지 않는지를 본 테스트 도구로서 확인할 수 있었다. In recent years, there has been a rapid and wide spread of robot system in our lives and with the ever increasing the requirement of user for robot functionality, the software component is increasingly sophisticated and complicated. Accordingly it is inevitable to employ a standardized software platform. The OPRoS is open standard software platform based on component for robot system. When the software components were developed, it has got to validate the conformity of robot software components which comply with the OPRoS standard specification. In this paper, we deal with the design and implementation of the structural conformance test suite to verify and validate the conformance of components to be developed by user. As the results of some experiments, we could verify it from this test suite whether the components satisfied standard requirement or not.
