Thermal Activation of Boron- and Phosphorus-Doped Amorphous Silicon and the Contribution to Improved Efficiency in Hydrogenated Amorphous Silicon Solar Cells

김가현 한국물리학회 2019 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.75 No.9

Hydrogenated amorphous silicon (a-Si:H) is an interesting candidate as an absorber material for solar cells. Despite the wealth of research to improve the efficiency of a-Si:H solar cells by improving either the material quality of the absorber layer or by means of light trapping approaches, efforts to improve the efficiency by means of doped layer manipulation are relatively rare. In this work, single-junction a-Si:H solar cells with improved efficiency due to thermal activation of doped layers via thermal annealing will be presented. Temperature-dependent dark conductivity measurements revealed that p- and n-type doped a-Si:H materials show different equilibrium temperatures. Ex- ternal quantum efficiency at different annealing temperatures revealed that front surface collection probability was improved with the activation of a p layer, after which the collection probability of the back surface was improved with the activation of an n layer.

We studied on the effect of the rational and emotional evidence on decision making. After selecting sufficient discussion topics, they were asked about their position and background on each subject based on their knowledge. As a result, most subjects have already established their ideas through existing prior knowledge. Therefore, the newly added information did not change its location. Although it is difficult to change human judgment and conclusion in a moment, it is found that sensitive knowledge varies more than rational knowledge in the case of change.

팝 아트 회화에서 분홍색의 의미와 상징성 연구

김가현,안진의 한국기초조형학회 2021 기초조형학연구 Vol.22 No.2

The purpose of this research is to draw the expression characteristics of the color pink and expand the symbolic meaning of Pop Art paintings that have given a strong visual effect to the public. For this, I.R.I Image Scale was used to analyze the color scheme imaging of works that were particularly prominent in the use of the color pink among paintings that appeared in the UK, which was the starting point of Pop Art, the US, which was the center of Pop Art, and Japan and China, which took various forms of spread. As a result of the research, leading with UK Pop Art which had political and social criticism or satirical character, US Pop Art expressed the reality of modern people becoming insensible in the repetitive mass media and overflowing products caused by industrialization through popular images. At this time, the color pink appeared as a feature that was fancy and attracting attention. Japanese Pop Art was reinterpreted as Neo-Pop Art, which was fused with “kawaii” animation to suit the national character, and has established a unique style of Japan, and the pink color showed fantastic images like animation. Chinese Pop Art was Political Pop Art as a Cynical Realist, in which Chinese artists satirized or accused the political situation of China in the 1970s, which experienced political state of confusion. The pink used in Chinese Pop Art was expressed as a cold pink with high attention to fit the content of cynical critique of reality. Pink is often used as a fragile and feminine color image. However, as a result of analyzing Pop Art paintings of each country in which pink was used, it was confirmed that pink caused a dynamic and fantastic color psychology to the public, and that it has a strong characteristic that is fancy or attracts attention. This overwhelming visual expression characteristic of pink has a very deep connection with Pop Art that expresses desire based on popularity, consumption, and fashionableness, and it is suitable for expressing Pop Art. It is expected that this research will contribute to the expansion of the meaning and symbolism of the color pink. 본 연구는 대중에게 강력한 시각적 효과를 주었던 팝 아트(Pop Art)회화를 대상으로 분홍색의 색채표현특징을 도출하고 상징적 의미를 확장하는 데 있다. 이를 위해 팝 아트의 출발점이었던 영국, 중심이되었던 미국, 다양한 확산의 모양을 띠었던 일본과 중국에 나타나는 회화 가운데 특히 분홍색의 활용이두드러진 작품의 배색 이미지를 I.R.I Image Scale로 분석하였다. 연구 결과 일상적이고 대중적인 이미지를 통해 정치적 사회 비판이나 풍자적인 성격을 가진 영국 팝 아트를 필두로, 미국 팝 아트는 산업화로 인해 넘쳐나는 상품과 반복되는 대중 매체 속에서 무감각해지는 현대인의 실상을 표출하였으며, 이때분홍색은 화려하고 주목성이 강한 특징으로 나타났다. 일본 팝 아트는 국가적 성격에 맞게 ‘가와이이(可愛い)’한 애니메이션과 융합된 네오팝 아트(Neo-Pop Art)로 재해석되며 일본만의 독자적인 양식을 구축하였으며, 분홍색은 애니메이션처럼 환상적인 이미지를 보여주었다. 중국 팝 아트는 문화대혁명과 천안문 사태 등의 정치적 혼돈을 겪은 1970년대 중국 작가들이 중국의 정치적 상황을 풍자하거나고발하는 냉소적 사실주의(Cynical Realist)로써 정치적 팝 아트(Political Pop Art)였다, 이때 사용된분홍색은 냉소적인 현실 비판이라는 내용에 걸맞게 주목성 높은 차가운 분홍으로 표현되었고기존의 사회주의적 사실주의와는 다른 개성적인 이미지로 작용했다. 분홍색은 종종 유약하고 여성적이라는색채 이미지로써 통용된다. 하지만 분홍색이 사용된 국가별 팝 아트 회화를 분석해본 결과, 분홍색은대중에게 다이나믹하며 환상적인 색채 심리를 유발하였고, 화려하거나 주목성이 강한 강렬한 특징이 있다는 점을 확인할 수 있었다. 이 점은 분홍색이 인간의 과시 욕망과 주목받고자 하는 욕망이 투영된색채임을 확인하는 근거가 되기도 하였다. 이러한 분홍색의 압도적인 시각적 표현특징은 대중성, 소비성, 유행성을 기반으로 욕망을 표출하는 팝 아트와 매우 깊은 연관을 갖고 있으며, 팝 아트를 표현하는데매우 적합한 것이었다. 본 연구가 분홍색의 색채상징 의미의 확장에 기여되길 기대한다.

Purpose: This study compared the functional and cosmetic treatment outcomes of intramedullary nailing (IM nail) and minimally inva- sive plate osteosynthesis (MIPO) for distal tibia shaft fractures. Materials and Methods: Forty-eight patients with distal tibia shaft fractures (distal 1/3 of the diaphysis, AO/OTA [AO Foundation/ Orthopaedic Trauma Association]) 43 managed by an IM nail (n=30) or MIPO (n=18) who had minimum one-year follow-up were en- rolled in this study. The radiological, functional, and cosmetic outcomes in the two groups were compared retrospectively. Results: All patients achieved bone union. The mean bone union time of the IM nail and MIPO groups was 18.5 and 22.6 weeks, respec- tively (p=0.078). One patient in the MIPO group showed posterior angulation and valgus deformity of more than five degrees. The mean American Orthopaedic Foot and Ankle Society (AOFAS) functional scores were similar: 83.3 in the IM nail group and 84.6 in the MIPO group (p=0.289). The most salient difference was the cosmetic result of the surgical scar. The length of the scars around the ankle in the IM nail group was significantly smaller than the MIPO group (2.6 cm vs. 10.6 cm; p=0.035). The patient satisfaction survey of surgical scars revealed a significantly higher satisfaction rate in the IM nail group than in the MIPO group (93% vs. 44%; p<0.001). Conclusion: This study showed that both treatment methods for distal tibia shaft fractures have similar therapeutic efficacy regarding the radiological and functional outcomes. On the other hand, the IM nail technique showed superior cosmetic outcomes than the MIPO technique. IM nails may be more recommended in patients with high demand for cosmetic results.

Effect of a multidisciplinary program to improve organ donation in the emergency department

김가현,이수훈 대한응급의학회 2020 대한응급의학회 학술대회초록집 Vol.2020 No.2

Introduction Organ transplantation is the best and only lifesaving treatment for patients with end-stage organ failure. The emergency department (ED) is at the forefront of critical care, but little attention has been directed towards the role of the ED in public health issues, such as organ donation. Therefore, we introduced and implemented an ED-inclusive organ donation improvement program (ODIP). In addition, we implemented a simple notification system that employed a messaging system in the electronic medical records (EMR) to improve its feasibility and for the timely notification of potential organ donors. Material & Method This study was a retrospective, observational study that assessed the influence of the multidisciplinary ED-inclusive ODIP on the number of deceased organ donors and identification of potential brain-dead donors. Data on organ donation were collected and managed by the Center for Korean Network for Organ Sharing in Korea Centers for Disease Control and Prevention and Korea Organ Donation Agency (KODA). The number of notifications of potential organ donation and the results of the donation process after brain death were analyzed for all ED patients during the study period. Result There was a significant increase in deceased organ donors per million population after the implementation of the ED-inclusive multidisciplinary ODIP of KODA compared to the pre-intervention period: 5.21 vs. 9.72, difference 4.51. The percentages of notifications made by ED staff in all notifications increased year by year from 2.3 (2014) to 5.4% (2018). This shows that the ED-inclusive ODIP improved the perspective of the ED sfaff. Through Table 5, longer periods contracted with KODA were associated with higher potential brain death identification rates (P<0.001). Conclusion The implementation of multidisciplinary interventions to improve organ donation in the ED can lead to improved organ donation awareness, better identification of potential donors, and successful organ donation in the ED.

김가현,장석환 한국다문화교육학회 2017 다문화교육연구 Vol.10 No.1

The purpose of this study is to conduct group art therapy for children aged from two through six who have multicultural familiy background and to find out its effects on their language development. As for the participants, fourteen children were categorized as an experimental group, whereas ten were classified as a control group, all of whom are from multicultural families who live in Jeolla Province, South Korea. One or two weekly sessions of group art therapy, which were 12 sessions in total, were conducted for the experimental group. Each session was about 30 to 40 minutes long. The Wilcoxon signed rank test was used for analyzing the results of the pre-post programs. In terms of quantitative measures, Receptive & Expressive Vocabulary Test(REVT) was performed to examine some effects on the children's vocabulary development. Cortisol tests were conducted to see the differences on stress levels before and after the art therapy program. The results showed that scores of the receptive and expressive vocabulary scales significantly increased, while he stress of the therapy group significantly decreased. These results showed that the group art therapy had positive effects on vocabulary development and stress of children from multicultural families. 본 연구는 집단미술치료가 다문화가정 아동의 언어능력과 스트레스에 미치는 효과에 대하여 검증하고자 한다. 본 연구의 대상자는 만 2세 이상 6세 이하의 아동으로 모(母)가 외국인인 다문화가정 아동들이다. 전라북도 I, J 지역에 거주중인 다문화가정 아동 중 실험집단 14명, 통제집단 10명을 선발하여, 실험집단에게는 주 1~2회, 30~40분씩, 총 12회기의 집단미술치료 프로그램을 실행하였다. 통제집단은 프로그램 실행 없이 동일한 기간이 지난 후 사후 검사를 실시하였다. 양적 분석을 위한 측정도구로 수용․표현 어휘력 검사와 코티졸 검사를 실시하였다. 본 연구에서 측정된 자료는 비모수적 검정 방법인 Wilcoxon signed rank test를 실시하여 분석하였다. 그 결과, 첫째, 집단미술치료 프로그램에 참여한 실험집단의 수용어휘력이 유의미하게 증가하였다. 둘째, 집단미술치료 프로그램에 참여한 실험집단의 표현어휘력이 유의미하게 증가하였다. 셋째, 집단미술치료 프로그램에 참여한 실험집단의 스트레스가 유의미하게 감소하였다. 따라서 집단미술치료는 다문화가정 아동의 어휘력 향상과 스트레스 감소에 긍정적인 효과가 있었음을 시사한다. 끝으로, 연구의 제한점과 후속연구에 대한 시사점을 논의하였다.
