Autoimmune pancreatitis (AIP) is rarely associated with pancreatic pseudocysts. AIP-associated pseudocysts requiring drainage despite steroid therapy are rather rare. We report a case of AIP with an infected pseudocyst requiring drainage despite steroid therapy. A 68-year-old male was diagnosed with AIP via pancreatic imaging, a high serum immunoglobulin G4 level, and steroid responsiveness. The AIP was accompanied by a pancreatic pseudocyst. Steroid therapy was prescribed, but the pancreatic pseudocyst became aggravated during steroid tapering. Endoscopic ultrasonography-guided cyst drainage was required; the pseudocyst then became completely resolved.

Purpose: The purpose of this study was to evaluate the efficacy of applying a defecation encouragement program for patients undergoing total knee replacement arthroplasty (TKRA). Methods: This program was based on the nursing best practice guideline: prevention of constipation in the older adult population by the National Guideline Clearing House (NGC) in 2011, which included fluid intake, bowel training, and abdominal and pelvic floor exercises. A team of one orthopaedic clinical nurse specialist and six orthopaedic nurses with a 10 years of clinical experience applied and assisted patients with the program. Formal counsel was provided by one orthopaedic doctor, one gastroenterologist, and one exercise therapist. Patients who defecated one day prior to or on the day of TKRA surgery were included. Data collected from 72 subjects were analyzed using SPSS/WIN 21.0. Results: Time until first defecation after surgery was 2.4±1.1 days in experimental group, which was significantly shorter than the 3.5±0.9 days in control group (t=4.28, p<.001). Constipation assessment scale showed significantly lower points (t=2.55, p=.013) in experimental group (1.3±1.2) compared to control group (2.6±2.6). The experimental group and control group were 17.3±7.67 and 23.7±14.43, respectively, and the experimental group used less laxatives (t=2.83, p=.021). Conclusion: A defecation encouragement program was proved to be an appropriate nursing intervention for patients undergoing TKRA. This study confirmed that constipation is a nursing problem that can be sufficiently prevented if nurses are interested and encourage defecation.

The purpose of this study was to establish biomonitoring method for the assessment of the health of fish species in agricultural reservoirs polluted from various environmental contaminants. The ichthyofauna and fish community were investigated in the AsanHo and NamyangHo from September to November 2007. We measured abundance, size distribution, biomass, the number of fish with external and internal lesions, organosomatic index of the fishes collected in the AsanHo and NamyangHo. Dominant species were Lepomis macrochirus, Carassius auratus and the highest biomass were found in Cyprinus carpio, Carassius auratus in the AsanHo and NamyangHo, respectively. The composition of age in the population of Carassius auratus in the AsanHo and NamyangHo was stabled by size distribution analysis. The sex ratio of Carassius auratus were 1:0.36, 1:0.52 as female: male ratio in AsanHo and NamyangHo, respectively. The GSI of were 4.30, 1.69 of female and 1.45, 1.70 of male in AsanHo and NamyangHo, respectively. Most carp were 10-70 cm long in the AsanHo and 20-50 cm in the NamyangHo. The sex ratio of Cyprinus carpio were 1:0.42, 1:0.59 as female: male ratio in AsanHo and NamyangHo, respectively. The GSI of were 0.16, 3.46 of female and 0.93, 2.37 of male in AsanHo and NamyangHo, respectively. Of the 227 fish examined, 1.8% had some type of external lesion in AsanHo and 10% in NamyangHo. Overall, HAI scores ranged from 10-60 and HAI scores of AsanHo relatively lower than that of NamyangHo.

The atmospheric corrosion rate were measured in Asan area for four years according to ISO 9224. The tested metals chosen as the most frequently used in industry, aluminum were copper, carbon steel, weathgering steel, and galvanized steel. The assessed corrosivity categories was 3 in average. The corrosivity categories of asan area was higher than typical rural area and even urban area, whereas it slightly lower than marine area. The results were discussed, specially as the regional climatic characteristics.

The color enhancement for natural Zambian amethyst of low quality was carried out by the hydrothermal treatment method. The hydrothermal treatment conditions were as follows: reaction temperature; $300^{\circ}C$, duration; 30 hrs, filling; 40%, solvent; 6 M-HCI solution. The reddish purple amethyst of high quality was obtained under these conditions. From the result of ICP/AES, it was known that color enhancement was affected by a Fe elemental content to exist in the inside of natural Zambian amethyst. Also, from the result of UY-VIS-NIR, it was shown that the absorption peak at 550 nm after hydrothermal treatment is slightly lower than those of non-treated natural Zambian amethyst. In this study, it was known that hydrothermal treatment method was a way to suitable for increase of commercial value of natural Zambian amethyst.

연안의 방조제 건설은 하천수와 바다물의 교환을 인위적으로 차단하고, 방조제 내부에는 호수를 형성하게 된다. 이렇게 형성된 인공호수의 수질은 호수로 유입되는 하천의 수질에 크게 영향을 받을 수 있으며, 인공호수의 수질이 악화되면 인근 해양생태계에 영향을 미칠 수 있다. 본 연구는 인공호수의 물이 바다로 방류될 때 해양생태계에 어떠한 영향을 미칠 것인지를 예측하고자 수행되었다. 방조제 건설로 이미 형성되어 있는 시화호, 아산호, 부사호와, 현재 건설중인 새만금 방조제로 인하여 형성될 호수의 유입 하천인 만경강에서 표층수를 채수하여 둥근성게(Strongylocentrotus nudus)의 정자와 수정란을 이용한 생물 검정을 실시하였다. 담수호의 수질을 해양생물을 이용하여 평가할 수 있도록 하기 위하여 시료의 염분을 조절하면서 실험을 실시하였다. 정자를 이용한 수정 실험 결과, 시화호에서는 수정률에 영향을 미치지 않았고, 아산호와 부사호에서는 약간의 영향이 있었으나 그 정도는 미약하였다. 반면, 만경강의 경우 수정률의 저해가 상당히 크게 나타났다. 수정란을 이용한 발생 실험 결과, 시화호, 아산호, 부사호에서는 약간의 영향이 나타난 반면, 만경강의 경우는 매우 큰 영향이 나타났다. 이들 실험 결과를 종합하면, 시화호, 아산호, 부사호의 수질은 대체로 양호하나, 만경강의 수질은 크게 우려되는 수준이었다. 따라서, 앞으로 건설될 새만금 호수와 인근 해양생태계를 보전하기 위해서는 만경강의 수질 개선을 위한 대책이 마련되어야 할 것이다.

동결절편검사는 수술과 연계하여 암 전이 여부를 판단하기 위한 응급한 병리검사가 필요할 때 이용된다. 합성곱 신경망은 이미지 분류에 뛰어난 성능을 보이는 딥러닝 기법으로 본 논문에서는 이를 이용하여 유방암 전이 여부를 자동적으로 진단하는 방법을 제안한다. 실험과정은 전처리, 학습, 후처리의 과정으로 구성되어 있으며, 합성곱 신경망으로는 Resnet-18 모델을 사용하였다. 실험결과 예측 정확도 및 종양의 최대 길이 정합 여부를 점수로 환산하여 약 0.514 의 결과를 보였다.

70년대 이후 서해 연안 개발 사업에 의해 아산만은 서해안 개발의 대표적인 지역으로 환경 변화의 속도가 그 어느 곳보다 빠르며, 방조제 건설과 간척지 개발로 인한 해안선의 변화와 항만 건설에 따른 준설 작업으로 인한 수심의 변화가 생기고 있는 지역이다 (Fig. 1). 그러나 이러한 급격한 변화 과정을 겪고 있는 아산만에서의 해수 순환과 오염물 확산의 문제에 대한 구체적인 연구 성과가 미비한 실정이다. (중략)
