| 1 | Overcoming the fundamental light-extraction efficiency limitations of deep ultraviolet light-emitting diodes by utilizing transverse-magnetic-dominant emission显示文摘While the demand for deep ultraviolet(DUV)light sources is rapidly growing,the efficiency of current AlGaN-based DUV light-emitting diodes(LEDs)remains very low due to their fundamentally limited light-extraction efficiency(LEE),calling for a novel LEE-enhancing approach to deliver a real breakthrough.Here,we propose sidewall emission-enhanced(SEE)DUV LEDs having multiple light-emitting mesa stripes to utilize inherently strong transverse-magnetic polarized light from the AlGaN active region and three-dimensional reflectors between the stripes.The SEE DUV LEDs show much enhanced light output power with a strongly upward-directed emission due to the exposed sidewall of the active region and Al-coated selective-area-grown n-type GaN micro-reflectors.The devices also show reduced operating voltage due to better n-type ohmic contact formed on the regrown n-GaN stripes when compared with conventional LEDs.Accordingly,the proposed approach simultaneously improves optical and electrical properties.In addition,strategies to further enhance the LEE up to the theoretical optimum value and control emission directionality are discussed. | Dong Yeong Kim Jun Hyuk Park Jong Won Lee Sunyong Hwang Seung Jae Oh Jungsub Kim Cheolsoo Sone EFred Schubert Jong Kyu Kim | 2015 | Light(Science & Applications)2015，4，1： | 6 |

在社会变迁下建筑学对社会现象和地形条件如何作出回应,如何演化变迁?对此我很有兴趣。本项目就以近年伴随技术发展而日益勃兴的电子游戏文化为背景。电子游戏自20世纪50年代以来,已迅速成长为当今娱乐产业的支柱之一,不仅衍生出新的建筑样式,更重要的是凭借互联网和在线游戏流媒体形成了庞大的游戏社交群及社交网络,为游戏体验和游戏空间带来前所未有的社群性。 | christopher yah chuen shen cristina díaz moreno(指导) efrén garcía grinda(指导) | 2016 | 城市环境设计2016，0，1： | 1 |

| 20 | Quality of Life in Congenital Heart Disease Patients according to Their Anatomical and Physiological Classification显示文摘Background:Living well is as important as living longer.The objective of this study is to assess quality of life(QoL)in congenital heart disease(CHD)according to current AHA/ACC anatomical and physiological classification.Methods:Cross-sectional study examining the World Health Organization QoL Bref questionnaire(WHOQoL-Bref)in consecutive outpatient CHD patients from a single unit.Results:191 CHD patients were studied.Median age was 28±13 years and 59%were male.44(23%),115(60%)and 33(17%)CHD patients showed mild,moderate and great anatomical defects respectively while 69(36%)patients were in physiological Stage A,27(14%)in Stage B,84(44%)in Stage C and 11(6%)in Stage D.No significant differences were seen in relation the anatomical classification and the different sections of the WHOQoL-Bref questionnaire.CHD patients in Stages C and D had significant lower physical domain scores than patients in the Stage A(p<0.05).However,no significant differences were seen in the psychological,social relationships and environmental domains.The binary logistic regression analysis showed that having a higher educational level was a protective factor[OR 0.32(95%CI,0.12-0.87),p=0.026]while being married or cohabit was a risk factor[OR 3.46(95%CI,1.13-10.63),p=0.030]for having a worse rated QoL.Meanwhile,having a worse functional class(NYHA≥2)[OR 3.44(95%CI,1.20-9.81),p=0.021]was associated with dissatisfaction with health.Conclusion:Patients with advanced physiological stages scored lower on the physiological domain.No statistical significance was seen,according to the anatomical and physiological classification,in the psychological,social relationship and environmental domains. | Efrén Martínez-Quintana Hiurma Estupiñán-León Ana Beatriz Rojas-Brito Liuva Déniz-Déniz Alejandro Barreto-Martín Fayna Rodríguez-González | 2023 | Congenital Heart Disease2023，18，2： | 0 |
