Epstein-Barr virus(EBV) infection is common and usually asymptomatic in young infants and children. However, EBV infections in transplant recipients and other immunosuppressed patients can be fatal. EBV-related neurological complications in immunocompetent adults are extremely rare and self-limited. Acute disseminated encephalomyelitis(ADEM) may also follow EBV infection; ADEM is characterized by abrupt onset and rapid progression. We report an immunocompetent adult patient who developed diffuse meningoencephalitis with ADEM-like features caused by EBV infection. A 35-year-old Vietnamese woman was admitted presenting with urinary retention, altered mental status, and paraplegia. PCR of the patient's cerebrospinal fluid showed positive results for EBV. Brain and spine magnetic resonance imaging showed ADEM-like features. She was treated with acyclovir, steroid, and immunoglobulins. We report the case of an immunocompetent adult Vietnamese woman who presented with rapidly progressive diffuse meningoencephalitis associated with EBV infection and was treated with antivirals, corticosteroids, and immunoglobulins.

Colonic cryptococcosis presenting with chronic diarrhea in a person with advanced human immunodeficiency virus disease: a case report

Oh, Hyunjoo,Kim, Misun,Yoo, Jeong Rae,Boo, Sun-Jin,Heo, Sang Taek Institute for Medical Science 2022 The Journal of Medicine and Life Science Vol.19 No.1

Cryptococcus neoformans infection usually occurs in patients with advanced human immunodeficiency virus (HIV) infection or with a CD4 T lymphocyte count of <100 cells/µL. Pulmonary and central nervous system infections are the most frequently encountered forms of cryptococcosis; however, colonic cryptococcosis is uncommon. We describe the case of a 41-year-old antiretroviral-naïve man with HIV infection diagnosed eight years prior and intermittent diarrhea for 4 months who presented to the emergency department with a 1-day history of low-grade fever and confusion. Brain magnetic resonance imaging and cerebrospinal fluid analysis revealed normal results; however, he was diagnosed with Pneumocystis jirovecii pneumonia based on chest computed tomography and bronchoalveolar lavage analysis. Trimethoprim-sulfamethoxazole administration was initiated followed by antiretroviral treatment. Although his condition gradually improved, he developed fever and abdominal discomfort, and the diarrhea worsened. Endoscopy revealed a small ulcer in the distal transverse colon. Histopathological examination of a colon tissue sample revealed cryptococcal infection. He improved substantially during liposomal amphotericin B and fluconazole treatment. We encountered a rare case of colonic cryptococcosis that caused chronic diarrhea in a patient with advanced HIV infection. Colonic cryptococcosis should be considered when patients with acquired immune deficiency syndrome present with gastrointestinal symptoms.

본 연구는 선거에서 유권자에게 미치는 회고적 평가의 영향이 차별적이라는 점을 주장한다. 그러한 차별성의 발현 요인으로 본 연구는 유권자의 정당 호감도에 주목한다. 2014년 지방선거를 대상으로 분석한 결과, 특정 정당에 대해 편향적인 호감을 가진 응답자 집단에서는 대통령에 대한 회고적 평가의 영향력이 미미했던 반면, 두 정당에 대해 호감의 차이가 크지 않은 응답자 집단에서는 현직 대통령에 대한 평가가 긍정적일수록 여당 후보를 선택할 확률이 높아짐을 확인하였다. 또한 분석 결과, 당파적 속성을 지닌 정당일체감보다 정서적 속성을 띤 정당 호감도가 2014년 지방선거에서 유권자의 선택에 영향을 미친 보다 주요한 요인임이 확인되었다. 투표 선택에서 정당 일체감보다 정당 호감도의 영향이 보다 크다는 것은 대통령 임기 중반에 치러지는 선거에서 유권자의 회고적 평가가 정서적 요인과 관련되어 있다는 것을 보여준다는 점에서 이론적으로 흥미로운 발견이라고 할 수 있다. This study aims to show the retrospective evaluation exerting different influences on vote choices. Focusing on voters’ party preferences, which cause this difference, this study empirically analyzes vote choices in South Korea’s 2014 local election. The finding shows that voters who are indifferent to both parties made vote decisions that were affected by the evaluation on the incumbent president, while voters who have lopsided preferences remained unaffected. Furthermore, instead of relying on partisan consideration for party identifications, voters’ party preferences involving emotional properties were found to be the crucial factor in their vote choices for the 2014 local election. To sum up, it is worth noticing that this study verifies that voters’ retrospective evaluations interact with their party preferences which were intrinsically affectional in the 2014 mid-term election.

Severe fever with thrombocytopenia syndrome (SFTS) caused by the SFTS virus (SFTSV), a novel Phlebovirus, is endemic to South Korea, central and northeastern China, and western Japan. SFTS poses a threat to public health because of its high mortality and secondary transmission. Ticks and domestic animals are hosts for SFTSV in endemic areas. There is no specific treatment for SFTS, and avoiding tick bites is the best way to prevent infection. Early therapeutic plasma exchange (TPE) is a rescue therapy in patients with rapidly progressive SFTS. Here, we present a patient with SFTS who was improving on TPE but died suddenly due to acute lung injury after TPE. (Korean J Med 2020;95:211-215)

연구논문 : 한국인의 빈곤귀인과 복지태도: 구조방정식 모형 분석

이 논문은 가난에 대한 귀인(歸因, attribution)에 따라 복지 일반에 대한 태도가 어떻게 달라지는지를 분석한다. 한국에서는 2000년대 후반부터 무상급식과 경제민주화 등의 복지 이슈가 선거 결과를 좌우하고 정치 전반에 심대한 영향을 미치는 현상이 발생하고 있다. 이에 따라 복지 태도에 영향을 미치는 요인들에 대한 분석이 요구되고 있다. 기존 연구에 따르면, 복지수혜자로서 가난한 사람들에 대해 가지는 대중의 인식이 복지에 대한 태도에 영향을 미치는 것으로 조사되고 있다. 그러나 한국에서는 가난을 개인의 문제로 보는지, 혹은 사회 환경이나 구조에 의한 것으로 인식하는지, 그리고 이것이 복지에 대한 태도에 어떠한 영향을 미치는지에 대한 연구가 부재하다. 이에 이 연구에서는 구조방정식모형을 통해 가난에 대한 한국인의 인식과 복지 태도 간의 관계를 분석했다. 그 결과, 사회적 귀인은 복지 태도에 긍정적인 영향을, 개인적 귀인은 부정적인 영향을 끼친다는 점을 발견했다. 개인의 무능이나 빈곤층 특유의 어떤 행동방식이나 가치관 때문에 가난이 발생한다고 귀인을 하는 사람은 복지에 대해 부정적인 태도를 보이는 반면, 가난이 외부적, 환경적 요인으로 인해 발생한다고 보는 사람은 이 같은 부당한 결과를 시정하는 도구로서 복지를 긍정적으로 받아들였을 것으로 해석된다. 또한 기존 연구와 달리, 이념은 간접적으로만 복지태도에 영향을 미쳤으며, 소득, 교육수준, 연령, 지역 등의 변수는 빈곤귀인과 복지태도에 영향을 끼치지 못하거나 이념을 매개로 하여 간접적인 영향을 끼치는 것으로 나타났다. This study aims to analyze how attributions for poverty influence the public attitudes toward welfare. Since the late 2000s, the electoral politics in South Korea has been dominated by welfare issues such as the universal free school meals and economic democratization. However, we lack sufficient understanding of what comprises and affects welfare attitudes. In particular, the relationship between perceptions of poverty and welfare attitudes in South Korea has not yet attracted significant scholarly attention. Previous studies have suggested that the public perceptions of the poor who are the major beneficiaries of state subsidies might influence welfare attitudes. Therefore, in order to show the effects of perceptions of poverty on shaping welfare attitudes in South Korea, we analyze South Korean survey data by applying structural equation modeling (or SEM). As a result, it is found that societal attributions for poverty strongly correlate with positive attitudes toward welfare while individualistic attributions correlate with negative attitudes. If people attribute poverty to individualistic factors like dishonesty or incompetence, they are likely to show negative attitudes toward welfare. On the other hand, if they blame societal factors for poverty, they tend to express favorable attitudes toward welfare. Interestingly, the effects of income, education, age, and region are statistically insignificant and ideology has only indirect influences on welfare attitudes.

수직면 주행 로봇의 위치인식을 위한 시스템 개발

The localization of a mobile robot is necessary to perform autonomous tasks in a vertical plane. The odometer is a very simple and effective method, in case the absolute sensors (such as GPS) are unavailable or difficult to install. However, the method using robot’s driving wheels is incorrect because the error of odometer is accumulated and is generated due to the driving state of robot, wheel slip, larger bumps, etc. So we designed the caster system composed of the MEMS gyro sensors, the encoders fixed on caster wheel, and suspension systems. The proposed system is fused each sensor output through an Indirect Kalman Filter to determine an accurate position and to reduce on position’s error. We fixed the system on robot’s back side and experimented on it. Simulation and experimental results illustrate the efficacy of a proposed system on the vertical robot.

압록강 수풍수력발전소 소유권을 둘러싼 북중 갈등 및 해결(1945-1955)

The Sup’ung Hydroelectric power station that was first constructed in 1937 was jointly owned by Manchukuo and the Japanese Government-General of Korea. Yet, North Korea, after achieving independence and receiving the ownership of the power station from the Soviet military authorities, began to claim its sole ownership. During the Chinese civil war, although both Chinese Nationalist Party and Chinese Communist Party claimed a joint ownership of the power station and demanded North Korea to share the electricity produced, Pyongyang nevertheless expressed its opposition. Mao zedong’s request for the Soviet’s mediation was no use in resolving the dispute over the power station, due to both Stalin’s and Kim Il-sung’s unwillingness. As a result, China had to purchase the electricity produced by the power station from North Korea. The ownership dispute surrounding the Sup’ung Hydroelectric power station was only resolved in April 1955, when Pyongyang was heavily dependent on Beijing for postwar economic reconstruction and security concerns and when Beijing and Moscow were enjoying their honeymoon period. In short, the ownership dispute evidently demonstrates that China and North korea prioritized their own national interests even when the Cold War structure and the two countries’ socialist fraternity were being increasingly strengthened.

This dissertation investigates the cause of the Eurosceptic phenomenon that is increasing in political, economic and social aspects in the EU, doubting the extension of the Eurosceptic view might affect the European integration. In the previous researches, eurosceptiscism is mainly discussed about the meaning, the deployment and the structure and characteristics of parties. For example, the analysis of party-based euroscepticism, the classification of eurosceptic attitudes and the epoch-making of extreme-right parties. This article, however, focuses on the strategic use of eroscepticism for the political parties for competing parties. The hypotheses of this study is that anti-Europe issues are utilized strategically in both of right and left parties, and the anti-Europe issues are mostly for getting legal right and vested interest of parties. To prove this, this article tries to suggest the case study of italian political parties. In the case study, first, the identities of political parties of an object of study are correlated with eurosceptic discourse? second, through the change of party agenda, the strategic use of eurosceptic is observed? third, anti-Europe issue which is selected by these parties has essential cognition about the European integration? This work might contribute to provide deepen conception of eroscepticism phenomena which is spreading out on EU.

In this study, the vertical distribution of giant jellyfish analyzed echo counting method and such survey methods as sighting and trawl were used to compare its density estimates. In May and July 2021, surveys were conducted in the East China Sea and the coastal waters of Korea. As a result, Nemopilema nomurai were evenly distributed in all water layers in East China Sea in May and July. When considered the correlation by each survey methods, it is possible to identify jellyfish in the surface area by sighting method and using sampling net; however, it has a low correlation with acoustic estimates due to marine environmental factor such as weather condition, wind and atmospheric pressure. Therefore, the result can be utilized by basic data when estimating jellyfish’s distribution patterns and density estimates from each survey methods hereafter.
