Daylight is highly beneficial for improving the indoor environmental quality and reducing building energy consumption, daylighting applications are scarcely considered, especially during the care facility design process, because of lack of previous studies on elderly- light environment and complex simulation process. Therefore, daylighting process were performed using ECOTECT, which has various advantage such as easy user interface and simple simulation processes. Moreover, dynamic daylight simulation were performed using whether data. Static simulation are performed to compute static metrics such as daylight factor, whereas dynamic simulation are performed for dynamic metrics such as daylight autonomy and useful daylight illuminance using annual weather data On the basis of daylight autonomy and useful daylight illuminance analysis result, variations in annual daylight performances. A parametric and regression analysis of the window-to-wall ratio and visible transmittance showed that daylight factor, daylight autonomy increased with window-to-wall ratio and visible transmittance. It can be concluded that this new daylight criteria. useful daylight illuminance, will enable architect to obtain better fenestration design.

윤영,Yun Young 한국정보통신학회 2004 한국정보통신학회논문지 Vol.8 No.7

본 논문에서는 DC 바이어스 소자와 정전파괴 보호회로를 MMIC상에 모두 내장한 완전집적화 K/Ka밴드 광대역 증폭기 MMIC를 제작하였으며, 따라서 MMTC의 동작을 위해서는 프린트기판상의 외부소자가 불필요하였다 DC 바이어스 용량성소자로서는, 소형의 SrTiO3 (STO) 커패시터를 MMIC 내부에 집적하였으며, DC feed 소자로서는 소형의 LC병렬공진회로를 집적하였다. 그리고 정전파괴방지를 위해서는 소형의 LC병렬공진 정전파괴 보호회로를 MMIC의 입출력부에 내장하였다. 정전파괴 보호회로에 의해 정전파괴전압은 10 V에서 300 V까지 개선되었다. 광대역에 걸쳐서 양호한 RF특성과 안정도를 보장하기 위해서, 프리매칭 기법과 RC병렬 안정화 회로가 이용되었다. 제작된 MMIC는 K/Ka 밴드의 광대역(17-28 GHz)에 걸쳐서 $20{\pm}2$ dB의 전력이득, $21{\pm}1.5$ dBm의 1dB 이득 압축점 (P1dB)의 양호한 RF특성을 보였다. 그리고 제작된 MMIC로부터 DC에서 동작주파수이상의 광대역에 걸쳐서 안정화 특성을 관찰 할 수 있었다. 제작된 MMIC의 면적은 $1.7{\pm}0.8$ mm2이었다. In this work, high performance broadband amplifier MMIC including all the matching and biasing components, and electrostatic discharge (ESD) protection circuit was developed for K/Ka band applications. Therefore, external biasing or matching components were not required for the operation of the MMIC. STO (SrTiO3) capacitors were employed to integrate the DC biasing components on the MMIC, and miniaturized LC parallel ESD protection circuit was integrated on MMIC, which increased ESD breakdown voltage from 10 to 300 V. A pre-matching technique and RC parallel circuit were used for the broadband design of the amplifier MMIC. The amplifier MMIC exhibited good RF performances and good stability in a wide frequency range. The chip size of the MMICs was $1.7{\pm}0.8$ mm2.

주기적 홀을 가지는 접지 금속막을 이용한 저임피던스/단파장 선로와 MMIC용 소형 레트레이스에의 응용

윤영,Yun, Young 한국전자파학회 2003 한국전자파학회논문지 Vol.14 No.7

본 논문에서는 GaAs MMIC상의 수동소자의 소형화와 저임피던스화를 위하여, 주기적 홀을 가지는 접지금속막 선로구조를 제안하였으며, 그 결과 종래의 마이크로스트립 선로에 비해 선로의 저임피던스화와 선로파장 축소를 실현하였다. 상기 선로구조를 이용하여 CaAs기판상에 15 $\Omega$ 임피던스라인으로 MMIC용 레트레이스를 제작한 결과, 종래의 마이크로스트립 선로를 이용하여 제작한 레트레이스에 비해 선로폭은 종래의 1/40인 20 $\mu\textrm{m}$였으며, 레트레이스의 면적은 종래의 약 9.3 %인 0.375 mm$^2$이었다. 상기 레트레이스로부터 20~30 GHz 사이에서 양호한 RF특성을 관찰할 수 있었다. In order to realize miniaturized and low-impedance MMIC passive component, a novel microstripline structure employing periodically perforated ground metal was proposed. The novel microstripline structure showed much lower impedance, and shorter guided-wavelength than conventional one. Using the novel microstripline with periodically perforated ground metal, a miniaturized 15 $\Omega$ ratrace was fabricated. The line width of the ratrace was 20 $\mu\textrm{m}$, and the size of it was 0.375 mm$^2$, which is 9.3 % of conventional one. The ratrace exhibited good RF performances from 20 to 30 GHz.

게이트 절연막에 의한 다이아몬드 MIS (Metal-Insulator-Semiconductor) 계면의 전기적 특성 개선과 전계효과 트랜지스터에의 응용

윤영,Yun, Young 한국전자파학회 2003 한국전자파학회논문지 Vol.14 No.6

본 논문에서는 비 산화물인 불소화합물 게이트절면막을 이용하여 박막반도체 다이아몬드 MS계면(Metal-Insulator-Semiconductor Interface)의 전기적 안정화를 실현하였다. 특히 산소 게터링 효과(Oxygen-Gettering Effect)에 의한 표면준위 억제를 통해, 박막반도체 다이아몬드 MIS계면에 있어서 최적의 전기적 특성을 부여하는 BiF2 게이트절연막을 개발하였다. 본 논문의 결과에 의하면, BaF$_2$ 게이트 절연막을 이용하여 제작한 A1/BaF2/diamond MIS 다이오드와 MISFET(Metal-Insulator-Semiconductor Field Effect Transistor)로부터 저농도의 ~10101/$\textrm{cm}^2$ eV의 표면준위밀도가 관측되었고, 그리고 이제까지 발표된 다이아몬드 박막반도_체 FET중 최고치인 400 $\textrm{cm}^2$/Vs의 유효이동도가 관찰되었다. Diamond MIS(Metal-Insulator-Semiconductor) diodes and MISFETs(Metal-Insulator-Semiconductor Field Effect Transistors) were fabricated by employing various fluorides as gate insulator, and their electrical properties were closely investigated by means of C-V measurements. The A1/BaF$_2$/diamond MIS structure exhibited outstanding electrical properties. The MIS diode showed a very low surface state density of ∼10$\^$10//$\textrm{cm}^2$ eV near the valence band edge, and the observed effective mobility(${\mu}$$\_$eff/) of the MISFET was 400 $\textrm{cm}^2$/Vs, which is the highest value obtained until now in the diamond FET. From the chemiphysical point of view, the above result might be explained by the reduction of adsorbed-oxygen on the diamond surface via strong chemical reaction by the constituent Ba atom in the insulator during the film deposition(Oxygen-Gettering Effect).

본 논문에서는 CSP(Chip Size Package)를 이용하여 정합소자 및 모든 바이어스소자, ESD(Electrostatic Dis-charge) 보호소자를 MMIC상에 완전집적한 K/Ka밴드 광대역 MMIC chip set에 관하여 보고한다. CSP에 대해서는 이방성 도전필름인 ACF(Anisotropic Conductive Film)를 이용하였으며, 그 결과 MMIC 패키지 프로세스가 간략화 되었고, CSP MMIC의 저 가격화가 실현되었다. MMIC상에 집적하기 위한 DC 바이어스 용량소자로서는 고유전율의 $STO(SrTi_{3})$ 필름 커패시터가 이용되었으며, DC 피드소자와 ESD 보호소자로서는 LC 병렬회로가 사용되었다. 그리고, K/KA 밴드 광대역에 걸친 MMIC의 정합과 안정도를 위해서는 프리매칭회로와 RC 병렬회로가 이용되었으며, 제작된 CSP MMIC는 광대역(K/Ka) 밴드에서 양호한 RF 특성을 보였다. 본 논문은 K/Ka 밴드의 주파수 대역에 있어서의 완전집적화 CSP MMIC 칩셋에 관한 최초의 보고이다. In this work, we developed fully integrated broadband MMIC chip set employing CSP(Chip Size Package) for K/Ka band applications. By utilizing an ACF for the RF-CSP, the fabrication process for the packaged amplifier MMIC could be simplified and made cost effective. $STO(SrTi_{3})$ capacitors were employed to integrate the DC biasing components on the MMIC, and LC parallel circuits were employed for DC feed and ESD protection. A pre-matching technique and RC parallel circuit were used to achieve a broadband matching and good stability fer the amplifier MMIC in K/Ka band. The amplifier CSP MMIC exhibited good RF performance over a wide frequency range in K/Ka band. This work is the first report of a fully integrated CSP amplifier MMIC successfully operating in the K/Ka band.

정복왕조의 대 고려 정책

윤영인 ( Peter Yun ) 한국정치평론학회 2013 정치와 평론 Vol.13 No.-

The Koryo dynasty (918-1392) generally adopted a very hostile foreign policy toward the Manchurian states of the Khitan, Jin, and later the Mongol empire. It has been asserted that such a policy may be explained by Koryo`s acceptance of the ideological validity of the Han Chinese concept of tribute system. However, this ignores the geopolitical reality of the time in which the Manchurian states represented a serious military threat to both the Chinese and Korean states, and this in turn pushed them toward friendly relations. Each state sought to maintain their autonomy and preserve the balance of power in East Asia by preventing the rise of a hegemonic power. Koryo`s policy was to maintain peaceful relations with Khitan and Jin in the guise of the “tribute system,” and to distance itself from Song China politically. Unlike the numerous studies of foreign relations of Koryo and Song China, but few studies have focused on the policies of the Northern Asiatic states toward Koryo. Manchurian states did not approach Koryo as they did Song China. The conquest dynasties of Khitan and Jin faced strong adversaries on all sides, and their main objective was to ensure the stability and security of the border region. In the end, they were content with nominal acknowledgement of “superiority” and submission of token amounts of “tributes” from Koryo. On the other hand, the Mongol`s policy toward Koryo was entirely different. The “Chinese World Order” during the Mongol period was not a continuation of the “tribute system” of the earlier Koryo period but represented a new world order imposed by the Mongol empire.

한국인들의 영어무기파열음 발음교정 효과에 대한 연구

윤영도 ( Yung Do Yun ),이나래 ( Na Rae Lee ) 한국외국어대학교 언어연구소 2012 언어와 언어학 Vol.0 No.57

An English professor and a Korean professor trained 18 Korean students, resectively. They learned how to pronounce English unaspirated stops. The English professor asked the students to repeat after him and corrected their mistakes. The Korean professor explained why and how Korean stops and English stops differ from each other, and corrected their English pronunciation by applying phonological information of Korean stops. We recorded the English unaspirated stops produced by the students both before and after the training, and compared the VOTs. The results show that the training methods used by the Korean professor was more effective than those used by the English professor.
