Reduction of Current Crowding in InGaN-based Blue Light-Emitting Diodes by Modifying Metal Contact Geometry

김가람,김장현,박의환,박병국 대한전자공학회 2014 Journal of semiconductor technology and science Vol.14 No.5

Current crowding problem can worsen the internal quantum efficiency and the negative-voltage ESD of InGaN-based LEDs. In this paper, by using photon emission microscope and thermal emission microscope measurement, we confirmed that the electric field and the current of the InGaN-based LED sample are crowded in specific regions where the distance between p-type metal contact and n-type metal contact is shorter than other regions. To improve this crowding problem of electric field and current, modified metal contact geometry having uniform distance between the two contacts is proposed and verified by a numerical simulation. It is confirmed that the proposed structure shows better current spreading, resulting in higher internal quantum efficiency and reduced reverse leakage current.

Deep Learning Approach for Solving a Quadratic Matrix Equation

김가람,김현민 영남수학회 2022 East Asian mathematical journal Vol.38 No.1

In this paper, we consider a quadratic matrix equation $Q(X) = AX^2+BX+C=0$ where $A, B, C \in \mathbb{R}^{n \times n}$. A new approach is proposed to find solutions of $Q(X)$, using the novel structure of the information processing system. We also present some numerical experimetns with Artificial Neural Network.

김가람,최재구,허지연,고장휴,서동국,이종욱,장영철 대한성형외과학회 2011 Archives of Plastic Surgery Vol.38 No.6

Purpose: A wart is caused by epidermal infection with the human papilloma virus. Although wart naturally disappears in some cases, it require treatment because of pain, aesthetic problem, and the possibility of malignant change. Conventional non-surgical treatment cannot be a fundamental solution for the pain and has such disadvantages as frequent recurrence and difficulties in achieving a satisfactory outcome. A surgical procedure was performed on patients with wart and the procedure had a good outcome. Methods: We investigated the gender, age, lesion site,mean treatment duration, and presence or absence of recurrence in 21 patients with a wart within the period of January 2007 to July 2011. For local lesions, primary closure, including subcuticular suture after the excision,was performed. If the defect size was too big to do primary closure, we performed rotation flap. For wide multiple lesions, a split thickness skin graft was performed. Results: Among the 21 patients, 12 patients were male and 9 patients were female, and their mean age was 42years (SD=17.38, range: 11~75 years). The lesion site was the foot in 10 patients, the hand in 8 patients, the face in 2 patients, and the scalp in 1 patient. The mean treatment duration was 13.5 days (SD=4.36, range: 6~15days) for the primary closure or rotation flap, and 18.5 days (SD=2.12, range: 17~20 days) for the skin graft. 20patients were cured without recurrence. No recurrence was observed in the patients who underwent primary closure or rotation flap. One of the two patients who underwent a skin graft of their wart that had covered their entire palm had local recurrence in part of her finger tips. Conclusion: We performed surgical procedure on recalcitrant wart. As a results, we can treat it with short treatment duration, low recurrence rate and less scarring and get high patient satisfaction.

포스트드라마 언어의 수행성- 비트겐슈타인의 '언어게임'에 의거하여

김가람 한국연극교육학회 2022 연극교육연구 Vol.42 No.-

본 연구는 철학자 비트겐슈타인의 ‘언어게임’ 이론을 통해 포스트드라마 속 연극 언어의 수행성을 분석하고자 한다. 1999년 한스-티스 레만이 ‘포스트드라마’라는 개념을 정립한 후, 공연계에서는 ‘수행성’에 대한 논의가 활발히 이루어져 왔다. 이 논문은 비트겐슈타인의 후기 이론을 담은 저서 『철학적 탐구』에 입각하여 포스트드라마가 어떻게 관객들과 새로운 ‘언어게임’을 만들어 나가고 있는지를 연구하고자 한다. 더 나아가, 수행성이 중점이 된 포스트드라마의 언어가 어떤 방식으로 구성원들 사이에서 공통된 의미를 갖게 되는가를 살펴본다. 포스트드라마의 연극 언어는 사전적 정의에서 머무르는 것이 아니라 그만의 방식으로 언어의 표의를 확장시켜나가고 있다. 관객은 감각을 통해 배우가 수행하는 행위의 의미를 파악하고, 그것이 공간 안에 함께 존재하는 구성원들 사이에서 규칙을 만들어냄으로써 ‘공적 언어’를 만들어낸다. 결론적으로 포스트드라마는 언어의 사용을 배제하는 것이 아니라 더 적극적으로 그 의미를 확장시킴으로써 ‘언어의 수행성’을 강조하는 결과를 만들어낸다. 이를 통해, 전통적 서사가 가지고 있던 언어의 획일화와 폭력성을 해체하고, 그 본연의 의미를 확장시켜 관객들로 하여금 삶의 변화를 유도하고 있다. 이에 본 논문은 비트겐슈타인의 ‘언어게임’ 이론을 포스트드라마에 접목하여 연구함으로써 포스트드라마 속 언어의 위상을 재정의하고자 한다.

Background/Aims: To evaluate the efficacy of proton pump inhibitors (PPIs) in reducing rebleeding and bleeding-related death rates after endoscopic gastric variceal obliteration (GVO) using N-butyl-2-cyanoacrylate (NBC). Methods: This study enrolled 341 patients who were consecutively diagnosed with and treated for bleeding gastric varices. The patients were divided into PPI and non-PPI groups, and their endoscopic findings, initial hemostasis outcomes, rebleeding and bleeding-related death rates, and treatment-related complications were analyzed. Results: The rate of initial hemostasis was 97.1%. rebleeding occurred in 2.2% of patients within 2 weeks, 3.9% of patients within 4 weeks, 18.9% of patients within 6 months, and 27.6% of patients within 12 months of the GVO procedure. A previous history of variceal bleeding (relative risk [RR], 1.955; 95% confidence interval [CI], 1.263 to 3.028; p = 0.003) and use of PPIs (RR, 0.554; 95% CI, 0.352 to 0.873; p = 0.011) were associated with rebleeding. Child-Pugh class C (RR, 10.914; 95% CI, 4.032 to 29.541; p < 0.001), failure of initial hemostasis (RR, 13.329; 95% CI, 2.795 to 63.556; p = 0.001), and the presence of red-colored concomitant esophageal varices (RR, 4.096; 95% CI, 1.320 to 12.713; p = 0.015) were associated with bleeding-related death. Conclusions: The prophylactic use of PPIs reduces rebleeding after GVO using NBC in patients with gastric variceal hemorrhage. However, prophylactic use of PPIs does not reduce bleeding-related death.

봄철 황해의 중형동물플랑크톤 군집 구조

김가람,강형구 한국해양과학기술원 2020 Ocean and Polar Research Vol.42 No.4

We investigated mesozooplankton in the Yellow Sea in spring to understand its community structure and relationship with environmental factors. Total mesozooplankton density ranged from 1,542 to 7,367 ind. m-3 and the biomass ranged from 3 to 42 mg C m-3. The total density and biomass had a positive relationship with chlorophyll-a (chl-a) concentration. The mesozooplankton community was divided into two groups at 125.5 E by cluster analysis: one was an inshore group and the other was an offshore group. The inshore group of mesozooplankton was of high density but low diversity, while the offshore group was of high diversity but low density. Copepod Acartia hongi and its copepodites were the most abundant species, comprising 27.8% of the total mesozooplankton density. A. hongi was especially abundant at the inshore, serving as the indicator species of the inshore group. Redundancy analysis found a positive relationship between the density of A. hongi and chl-a concentration. Oithona similis and Centropages abdominalis were 2nd and 3rd dominant species comprising 9 and 7% of the total density, respectively. The density of O. similis was positively related to water depth, but C. abdominalis was related to chl-a concentration. Chl-a concentration seems to influence significantly the mesozooplankton community structure in the Yellow Sea in spring, rather than water temperature or salinity.

다중흐름모형을 적용한 반값등록금 정책 변동과정 분석

김가람,이일용 한국교육정치학회 2014 敎育政治學硏究 Vol.21 No.1

본 연구는 이명박 전 대통령이 공약으로 ‘반값등록금’을 제시한 2007년부터 2013년 현재 박근혜 정부까지의 ‘반값등록금’ 정책의 변동과정을 문제, 정치, 정책의 세 가지 흐름이 특정 순간에 결합하여 정책의 창이 열리고 이 때 정책혁신가가 중요한 역할을 한다는 Kingdon의 다중흐름모형을 적용하여 분석하였다. 구체적으로 반값등록금이 이슈화된 과정, 이해관계자들로 인한 정책의 형성과정, ‘반값등록금’이 다양한 형태로 변화한 정책대안의 변화과정, 정책대안의 확산과정 등을 살펴보았다. 분석결과는 다음과 같다. 첫째 ‘반값등록금’의 문제는 과거에서부터 지속되어오던 높은 수준의 등록금 문제가 황우여 원내대표의 ‘반값등록금’ 발언이라는 촉발기제로 인해 정책적 이슈가 되었다. 둘째, 정부와 정당 및 학생단체와 시민단체는 ‘반값등록금’ 정책의 변동과정에 있어서 주요한 역할을 하였으며 등록금과 관련한 다양한 정책대안을 만들어냈다. 셋째, ‘반값등록금’과 관련한 정책대안은 크게 ‘고지서상의 등록금 반값’과 ‘등록금 부담의 반값’의 형태로 나타났다. 넷째, ‘반값등록금’ 정책의 결정적 정책혁신가는 각 정당과 정부이며, 정치의 흐름이 가장 큰 영향을 끼쳤다. This research attempts to analyze the change process of ‘half tuition’ policy from 2007 to 2013 based on the Kingdon’s multiple streams framework. This research reviews ‘half tuition’ issue raising process, related person’s policy formation process, change process of policy alternatives, and diffusion process of policy alternatives. The results of analysis are as follows. First, the ‘half tuition’ issue was politicalized by Hwang Woo Yea’s (representative of a party) ‘half tuition’ comment under circumstances of high tuition level. Second, government and political party play an important role in making various policy alternatives related with the ‘half tuition’. Third, policy alternatives related with ‘half tuition’ are appeared as two forms of ‘half tuition by a bill’ and ‘decrease of tuition burden’. Fourth, decisive policy entrepreneurs of ‘half tuition’ policy are government and each political party, and influence of politics stream is most important.
