Purpose: C1q nephropathy (C1qN) is a rare glomerulonephritis characterized by mesangial deposits, predominantly C1q, without the evidence of systemic lupus erythematosus (SLE). It showed various clinical courses, however, the clinicopathologic features of C1qN have not been well defined as yet. Methods: We retrospectively reviewed the clinicopathologic features of 11 patients (0.8%) diagnosed as C1qN among 1,403 patients aged 18 years who had undergone renal biopsy due to primary glo ≥-merular disease from Jan. 2000 to Jan. 2009. Diagnostic criteria of C1qN were as follows; 1) the presence of dominant or co-dominant immunofluorescence staining for C1q in the mesangium, 2) corresponding mesangial dense deposit by electron microscopy, and 3) lack of clinical evidence of SLE. Results: The male-to-female ratio was 6:5 and their mean age was 41.1±22.6 yrs (range, 19-69 yrs). Eight patients presented with urinary abnormalities and three with nephrotic syndrome. At the time of biopsy, three patients had hypertension. The mean value of 24-hour urine protein was 4.4±5.5g/day (range, 0.5-18.5g/day). On light microscopy, normal glomerular architecture (4/11) and segmental sclerosis (7/11) were observed. Complete or partial remission was achieved in six of the seven patients treated with immunosuppressive agents (steroid and/or immunosuppressants). Among these patients, two using steroid monotherapy had relapsed. The mean follow-up duration was 14±11 months (range, 2-31 months) and renal function deterioration was observed in three patients. Conclusion: C1qN showed various clinical manifestations and prognosis. Therefore, additional studies are needed to fully define the clinicopathologic features.

공연콘텐츠의 키치적 문화취향 수용에 관한 연구

안신영(Ahn, Shin Young) 건국대학교 글로컬문화전략연구소 2015 문화콘텐츠연구 Vol.0 No.5

본 연구는 공연예술분야의 뮤지컬 산업의 관객 개발과 작품해석에 초점을 맞춰 성공요인을 분석하는 기존의 선행연구에 대해 공연콘텐츠의 새로운 시각적 접근이 부족하다는 문제의식에서 출발한다. 본 논문의 목적은 키치적 특성을 보이는 뮤지컬을 중심으로 관객의 선호요소를 분석하여 공연 콘텐츠의 산업적 측면을 미적 개념인 키치로 접근하여 분석하고자 한다. 연구 방법으로는 문헌연구를 통해 연구의 특정요소를 정립한다. 사례분석과 사전 인터뷰, 설문조사를 통하여 키치에 대한 인식과 선호유형을 파악하고 수용자들에게 긍정적인 방향의 접근 방식을 모색한다. 연구 목적에 대한 분석 결과는 다음과 같다. 공연 콘텐츠의 키치적 문화 취향에 대해 설명하기 어려운 이유인 즉, 키치라는 단어가 갖고 있는 사회적 현상과 상황 그리고 개개인의 특징을 포괄적으로 담고 있기 때문이다. 하나의 의미로 정의하기에 어려운 개념으로 복합적인 순환구조를 걸쳐 오락적 키치, 상품적 키치, 예술적 키치로 공연콘텐츠의 키치적 문화취향을 나눌 수 있다. 수용자들의 취향 분석은 다음과 같다. 본 논문에서는 고관여 관람객과 일반 관람객으로 나누어 구분하는데, 먼저 고관여 관람객은 키치를 인식하고 있지만 유형적 접근에는 낯설고 익숙하지 않은 개념으로 인지하고 있으며, 일반 관람객은 키치 자체에 대한 인식 낯설지만 새롭고 독특한 경험을 추구하는 성향이 강해 키치적 문화취향에 대한 긍정적인 요인으로 작용한다는 것을 알 수 있다. This research begins with a critical mind, that performance contents are lacking on visual approach in regards to the advanced research that have mostly analyzed on success factors in the focus of audience development of the musical industry and art work interpretation of the performing arts field. The purpose of this thesis is to analyze the industrial aspects of performance contents in the approach of kitsch which is the aesthetic notion, through analyzing preference factor of audiences focusing on musical which shows characteristics of kitsch. As a method of research, it defines specific elements through literature research. The reason for having difficulty explaining in regards to cultural preference of kitsch on performance contents, is because the word kitsch itself contains comprehensive definition as characteristics of social phenomenon and individuals. As a difficult notion to be defined into one definition, it could share cultural preference of kitsch on performance contents, as a kitsch of entertainment, commerce, and art, through complex structure cycle. The analysis on preference of the recipients are as follows. This thesis have divided into two groups of high involvement audience and a general audience. Firstly, the high involvement audiences recognizes the typical approach as unfamiliar idea even though they are aware of the kitsch. It shows that cultural preference of kitsch makes positive effect on the general audiences, because they have a high tendency to pursue new and unique experience even though they are unfamiliar with kitsch itself.

Since human genome project finished, the cost for human genome analysis has decreased very rapidly. This results in the sharp increase of human genome data to be analyzed. As the need for fast analysis of very large bio data such as human genome increases, non IT researchers such as biologists should be able to execute fast and effectively many kinds of bio applications, which have a variety of characteristics, under HPC environment. To accomplish this purpose, a biologist need to define a sequence of bio applications as workflow easily because generally bio applications should be combined and executed in some order. This bio workflow should be executed in the form of distributed and parallel computing by allocating computing resources efficiently under HPC cluster system. Through this kind of job, we can expect better performance and fast response time of very large bio data analysis. This paper proposes a workflow-based data analysis system specialized for bio applications. Using this system, non-IT scientists and researchers can analyze very large bio data easily under HPC environment.

Oral and maxillofacial infection is the oldest and most common disease in human history. The infection ranges from the low-grade infection that only requires minimal treatment to the high-grade and life-threatening fascial space infection. In this study, the data on oral and maxillofacial infections were analyzed to aid in the diagnosis and treatment, and to predict the prognosis. This report was based on data from 831 patients with oral and maxillofacial infection (394 males and 437 females) who were hospitalized in the Department of Oral and Maxillofacial surgery of Chosun University Dental Hospital from January 1998 to May 2005. The ratio of males to females was 0.9:1. By age, patients between 60 and 70 years old were the greatest in number (17.1%), while only 5.9% of the patients were between 10 and 20 years old. The most common cause of infection was odontogenic origin (84.4%), followed by post-extraction infection (6.2%), unknown (5.9%), and trauma (3.5%). The most common fascial space involved was the buccal space (39.4%), followed by the canine (20.6%), submandibular (15.9%), pterygomandibular (9.5%), submental (7.6%) and sublingual (2.8%) space. The number of the involved fascial space was one (75.2%), two (19.8%), or more than three (5.0%). In terms of the treatment duration, the hospitalization period of 6 to 10 days was the greatest in number (49.9%). All patients had uneventful recovery without major complication. There are statistically significant correlations between age and treatment period, and the involved space and treatment period, but no correlations between the variables of sex and treatment.

Lichenoid dysplasia is a lesion similar to oral lichen planus with epithelial dysplasia. It can be clinically mistaken for oral lichen planus, but has histologic features of dysplasia and a true malignant predisposition. It is not a variant or transitional form of lichen planus but, instead, represents a distinct entity that has a true potential for malignant transformation. In addition to abnormal epithelial maturation and cytology, lichenoid dysplasia exhibits other histologic features that separate it from oral lichen planus. Lichenoid dysplasia and lichen planus share many clinical and microscopic features, leading to the frequent misdiagnosis of unrecognized lichenoid dysplasia as lichen planus. We experienced a case of lichenoid dysplasia in the oral mucosa. We treated this patient with surgical excision. The patient has now been followed for two months. It is important to recognize this precancerous condition and inspect the excision site and remaining oral mucosa during long-term follow-up.

Infective endocarditis remains an important, life-threatening infection despite improvements in diagnosis and management. Despite the decrease in rheumatic heart disease and the improvements in antibiotic prophylaxis, infective endocarditis has been reported with increasing frequency in the last few decades. Presumably, this is due to the rise in the incidence of intravenous drug users, carriers of prosthetic valves and other intracardiac devices, and the longer survival of patients with congenital heart disease. Despite the great advances in medical and surgical treatment, infective endocarditis is still a life-threatening disease with an estimated mortality of 27%. Infective endocarditis represents one of the few potentially fatal infections that may occur in a dental patient. Efforts to reduce the incidence of this disease usually take the form of appropriate antibiotic coverage before dental treatment, together with the establishment and maintenance of good oral health. This study is a case report of a patient who developed infective endocarditis after multiple tooth extractions due to chronic periodontitis of dental origin.
