The biological wastewater treatment system is known to have an important role in reducing the quantify of enteric virus in water environments. To clarify the roles of activated sludge microbes in decreasing the virus infectivity, the behavior of the virus in bacteria, protozoa, and metazoa was examined by pure or mixed culture system using poliovirus type 1(Lsc, 2ab strain). In the bacterial culture systems, the virus infectivity in the liquid phase decreased by a reversible adsorption of the virus to the bacteria or bacterial flocs. On the other hand, in the protozoa and the metazoa culture systems using T. pyriformis and P. erythrophthalma, respectively, with a variety of bacterial strains as prey, the main virus decrease mechanism of reversible adsorption in early stage was changed to irreversible predation, which was not eluted in this study. The virus decrease was more effective in the P. erythrophthalma culture system, which had high predation and floc forming abilities. However, in the mixed culture system of Z. ramigera and P. erythrophthalma, the more rapid reversible adsorption of virus to Z. ramigera flocs preceded the irreversible predation of P. erythrophthalma.

문맥염은 드문 질환으로 증상이 모호하여 조기진단이 어렵고 치료시기를 놓치면 높은 치사율을 보인다. 원인으로는 충수돌기염, 게실염, 감염성 췌장 괴사 등의 복강내 감염과 간경변이나 간암, 위암, 췌장암 같은 악성종양 및 골수증식성 질환, 혈액응고인자 결핍증과 같은 상태에서 이차적인 감염이 일어나서 생기기도 한다. 예후에 빠른 진단과 치료가 중요하여 저자들은 본원에서 경험한 6예를 통해 화농성 문맥 혈전증의 임상양상과 방사선학적 소견을 고찰해 보고자 하였다. 6예의 환자 모두 남자였으며 평균 추적관찰기간은 11개월(5~24개월), 평균연령은 54.3세(38~60세)였다. 문맥염의 추정 원인으로는 2예에서 담도염, 1예에서 급성 충수돌기염, 3예에서는 원인이 불분명하였다. 임상양상은 전예에서 발열과 오한, 우상복부 통증과 압통을 보였다. 일반혈액검사에서 6예에서 백혈구 증다증과 빈혈이 있었으며 3예에서 혈소판 감소를 보였다. 역동적 복부 전산화 단층 촬영상 전예에서 문맥혈전증이 보였으며 이 중 4예에서 상장간막 혈전증이 동반되어 있었다. 2예에서 간농양이, 2예에서 담즙종이 동반되어 나타났다. 문맥혈전증은 조영되지 않는 간내 문맥, 혈관내 저음영의 혈전소견, 간실질의 불균일한 조영증강, 변연부에 비해 중심부의 저음영 소견으로 나타났다. 치료는 6예 모두에서 광범위 항생제를 투여하였고, 그 중 1예에서 항응고요법을 병행하였다. 6예 모두 증상이 호전되었으며 항응고요법을 시행한 예에서 추적관찰시 혈전이 사라지고 간엽의 위축이 없이 회복되어 항응고요법이 문맥염의 호전에 도움이 될 것으로 생각되나 이에 대해서는 향후 더 많은 연구가 필요할 것으로 생각된다. Pylephlebitis, a suppurative thrombophlebitis of the portal venous system, is a rare complication of intra-abdominal sepsis usually followed by infection either in the region draining the portal system or in the structure contiguous to the portal vein. Early diagnosis and initiation of adequate antibiotic therapy is important for improving the long-term prognosis of patients suffering from this rare disease, so we retrospectively reviewed 6 cases of pylephlebitis. All patients were males with a mean follow-up of 11 months (range 5~24 months). Clinical symptoms consisted of fever (100%), right upper abdominal pain (100%), jaundice (33.3%), and diarrhea (16.6%). Anemia and leukocytosis were found in 6 patients. Suspected etiology was acute cholangitis in 2 patients, acute appendicitis in 1 patient and idiopathic in 3 patients. All patients were successfully diagnosed with dynamic CT scan which showed the presence of portal vein thrombosis (100%), superior mesenteric vein thrombosis (66.6%), liver abscess (33.3%), and biloma (16.6%). Patients were treated with the systemic administration of a broad spectrum antibiotics and 1 patient was given anticoagulant. Initial symptoms were improved in all patients and some beneficial effects of anticoagulation are expected to achieve the recanalization of thrombosis and prevent atrophic changes in the liver, but further studies on the kind of therapy are needed.

This research focuses on the disclosure patterns of related-party transactions and analyzes the relationship between these transactions and characteristics of companies in terms of disclosure. Because managers often exercise their discretionary powers through related-party transactions, disclosure of these transactions may include useful information for external investors in the form of specific transaction details. However, because the current accounting standards are unclear regarding footnote disclosures in reports containing information about related-party transactions, many users of accounting information have identified differences in disclosure methods in between individual firms. If discretionary accounting choices are allowed, then some managers may disclose only good news favorable to themselves; thus, the transparency and comparability of accounting information will deteriorate. In such cases, it is necessary to monitor and control large transactions between related parties to prevent corrupt practices. However, when this transaction information is arbitrarily hidden, this lack of disclosure increases information asymmetry among interested parties. This study focuses on disclosure patterns and hidden actions that conceal specific information about related-party transactions. We analyze firms’ corporate characteristics and identify factors affecting disclosure about related-party transactions. The empirical findings are as follows. First, we find that disclosure(footnote) quality decreases as the trade volume of related-party transactions increases. Second, in cases of propping, we confirm a significant decrease in the number of disclosures of related-party transactions. Lastly, according to the results of an analysis on differences in disclosure behavior by business groups, a decrease in disclosure associated with related-party transactions is observed in non-large business groups. In conclusion, firms that belong to large business groups and those that engage in propping tend to change their patterns of disclosure according to the manager’s discretionary decision-making. Therefore, in order to reduce information asymmetry in the stock market and improve the quality of accounting information, supervisory authorities must discuss institutional regulations to ensure adequate disclosure levels(quality) and encourage active disclosure. Most former research studies develop their arguments assuming that the nature of transactions causes information asymmetry while ignoring the loophole in the disclosure system of relatedparty transactions. Also, considering that studies on the disclosure standards associated with related-party transactions and the factors influencing disclosure are practically non-existent, this paper provides valuable information about related-party transactions and how the disclosure system fails to address issues related to them. By examining these issues, suggest that the problems related to the market’s biased perception of related-party transactions and the limitations of the information environment can be alleviated by taking complementary measures to improve disclosure standards. Furthermore, while discussion is ongoing about establishment of an effective monitoring system to prevent managers’ opportunistic decisionmaking during disclosure of related-party transactions, this thesis provides a suggested configuration and theoretical implications on the direction of future regulatory policy and oversight of relatedparty transactions through revision of the involved disclosure system.

폭발 하중을 받는 방폭문의 성능 평가

김태동(Tae Dong Kim),김진호(Jin Ho Kim) 대한기계학회 2020 大韓機械學會論文集A Vol.44 No.6

최근 폭발 하중을 받는 방폭문에 대한 연구가 활발히 진행되어지고 있는 추세이며, 국외에서는 여러 방폭 설계 기준을 제시하였다. 테러 공격이 국방 시설보다 일반 상업 건물에 집중되어지고 있으며, 보통의 구조 기술자들이 기본적인 수준의 방폭 설계를 수행할 수 있게 되었다. 이에 본 논문은 간단한 사례를 통하여 ANSYS Transient Structural을 사용하여 ductility ratio, support rotation angle을 계산한 뒤 방폭문(blast resistant door)의 방폭 성능을 살펴보았다. 폭발 하중의 정압만을 고려하여 해석을 수행하였으며, 2차원 설계 도면에서 CATIA Part Design을 통하여 각 부재들을 모델링하였고 CATIA Assembly를 통하여 부재들의 접촉 조건을 주어 3D 모델링을 진행하였다. μ =2.8734, θ=0.4941°라는 값을 얻을 수 있었으며 선정한 보호 수준에 적합하다는 결론을 도출하였다. Recently, research on the blast resistant door of the structures subjected to the blast load has actively been progressed, and various explosion proof design standards are presented abroad. Terrorist attacks have been concentrated in commercial buildings rather than military facilities, and normal structural engineers have been able to perform basic level explosion-proof designs. In this paper, we investigated the explosion resistance of blast resistant door after calculating the ductility ratio and support rotation angle using ANSYS Transient Structural through a simple case. The analysis was performed considering only the positive pressure of the blast loading and each member was modeled using the CATIA Part Design in a two-dimensional design drawing; 3D modeling was performed by providing the components" contact conditions through the CATIA Assembly. The values μ = 2.8734, θ = 0.4941° were obtained and conclusion was drawn that these values were suitable for the selected level of protection.
