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.

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.

This work presents an analytical model, so called modified LMTD method, to predict the thermal performance of finned-tube heat exchanger under frosting conditions. In this model, the total heat transfer coefficient and effective thermal conductivity of the frost layer were defined as a function of frost surface temperature. The surface temperature of the frost layer formed on the heat exchanger was calculated through the analysis of the heat and mass transfer process in the air and frost layer. To examine the validity of this analytical model, the computed results from the present model, such as heat transfer rate, frost mass and thickness of frost, were compared with the ones of the expermental work and LMED method.

Background/Aims: Pyogenic liver abscess remains a major diagnostic and therapeutic challenge, despite advances in diagnostic technology and new strategies for treatment. This study was conducted to compare the differences in clinical features and outcomes of pyogenic liver abscess according to age. Methods: In total, 166 patients were enrolled and included 63 (<65 years old, group 1), 62 (65-74 years old, group 2), 41 (>75 years old, group 3) patients in each group. We reviewed the medical records retrospectively including etiology, underlying diseases, characteristics of the liver abscess, laboratory and microbiologic findings, treatment, and outcome of the patients. Results: Group 1 had higher prevalence rates of male patients and chronic alcoholics, but lower prevalence rates of biliary disease, hypertension, and malignancy. In laboratory findings, group 2 had higher incidence of thrombocytopenia, elevated blood urea nitrogen and creatinine. There were no differences in symptoms and microbiologic findings in blood and pus among the three groups. Liver abscesses were more common in right liver in Group 1. The lengths of stay and the treatment modalities were similar in three groups. Conclusions: Although there were differences in sex ratio, etiology, underlying disease among the different age groups, they did not cause difference in treatment and clinical outcome of pyogenic liver abscess. Thus, we recommend active treatments in patients of all age. (Korean J Gastroenterol 2010;56:90-96)

본 논문에서는 VP9 디코더에 대한 행렬 기반의 정수형 역변환 구조를 제안한다. 제안하는 구조는 DCT(Discreste Cosine Transform), ADST(Asymmetric Discrete Sine Transform) 그리고 WHT(Walsh-Hadamard Transform)에 대한 알고리즘을 공유하며 버터플라이구조보다 하드웨어 리소스를 줄이고 제어하기 쉬운 하드웨어 구조이다. VP9 구글 모델 내 정수형 역변환은 버터플라이구조 기반의 정수형 역변환 구조를 가진다. 일반적인 버터플라이구조와는 달리 구글모델 내 정수형 역변환은 각 단계마다 라운드 쉬프트 연산기를 가지며, 비대칭 구조의 사인 변환을 포함한다. 따라서 제안하는 구조는 모든 역변환 모드에 대해 행렬계수 값을 근사하고, 이 계수 값을 이용하여 행렬연산 방식을 사용한다. 본 논문의 기술을 사용하면 역변환 알고리즘에 대한 모드별 동작 공유 및 버터플라이구조에 비해 곱셈기 수를 2배가량 감소시킬 수 있다. 그래서 하드웨어 리소스를 효율적으로 관리가 가능해진다. In this paper, we propose an efficient integer inverse transform structure for vp9 decoder. The proposed structure is a hardware structure which is easy to control and requires less hardware resources, and shares algorithms for realizing entire DCT(Discrete Cosine Transform), ADST(Asymmetric Discrete Sine Transform) and WHT(Walsh-Hadamard Transform) in vp9. The integer inverse transform for vp9 google model has a fast structure, named butterfly structure. The integer inverse transform for google C model, unlike universal fast structure, takes a constant rounding shift operator on each stage and includes an asymmetrical sine transform structure. Thus, the proposed structure approximates matrix coefficient values for all transform mode and is used to matrix operation method. With the proposed structure, shared operations for all inverse transform algorithm modes can be possible with reduced number of multipliers compared to the butterfly structure, which in turn manages the hardware resources more efficiently.

치과 콘빔 전산화단층 검사 시 갑상선 부위의 방사선 피폭선량을 최소화하기 위하여 보루스 (Bolus)를 이용한 차폐체를 제작하고, 방사선 차폐 효과와 영상의 적정성을 평가하였다. 치과용 콘빔 전산화단층검사 장비를 사용하여 치과방사선 두부 팬텀을 대상으로 갑상선의 좌, 우측 부위에 유리선량계를 부착시켜 방사선량을 측정하였다. 차폐체의 두께를 각각 10 mm, 20 mm, 30 mm로 다르게 하여 각 차폐체별로 흡수선량을 측정하여 차폐체를 사용하지 않았을 경우와 비교하였다. 8명의 평가자가 진료영상의 적정성을 여부를 평가하였다. 왼쪽 갑상선 부위에 30 mm Bolus 차폐체를 사용한 경우에는 결과값이 평균 342.67 μ㏉로 Bolus 차폐체를 사용하지 않고 측정한 결과값의 평균 431.22 μ㏉보다 20.7% 감소하였고, 오른쪽 갑상선 부위에 30 mm Bolus 차폐체를 사용한 경우에는 평균 424.56 μ㏉로 21.9%의 선량감소효과를 보였다. 진료 영상의 적정성은 평가자 모두 사용 가능하다 판단하였다. 결론적으로, 치과 콘빔 전산화단층검사 시 갑상선 부위의 방사선 피폭선량을 최소화하기 위해 제작된 Bolus 차폐체는 장해음영 없이 적정한 진단 영상 처리가 가능하고, 방사선차폐 효과가 있어 유용한 차폐체로 적용 가능할 것으로 사료된다. In order to minimize the radiation exposure dose of the thyroid site at dental cone-beam computer tomography, a protector using a Bolus was prepared, and the radiation shielding effect and the appropriateness of the image were evaluated. Using a dental cone-beam computed tomography (CBCT), a glass dosimeter was attached to the left and right sides of the thyroid for a dental radiation phantom, and the radiation dose was measured. The absorbed dose for each shield was measured by another method to 10 mm, 20 mm, and 30 mm-thickness, respectively. Eight evaluators evaluated whether or not the medical image is appropriate. When using a 30 mm Bolus shield at the left thyroid site, the resulting value is reduced by an average of 342.67 μGy by 20.7% from the average value of 431.22 μGy measured without using a Bolus shield, the right thyroid site In the case of using 30 mm Bolus shield, it showed a dose reduction effect of 21.9% with an average of 424.56 μGy. The adequacy of the medical image was judged to be usable by both evaluators. In conclusion, the dental cone-beam computerized tomography can be used as a useful shielding material because it has a radiation shielding effect and it is possible to treat the diagnosis of the bolus protector in the thyroid without any obstruction shade in order to minimize the radiation dose.
