김무성,김용,엄경숙,김성일,민석기,Kim, Moo-Sung,Kim, Yong,Eom, Kyung-Sook,Kim, Sung-Il,Min, Suk-Ki 대한전자공학회 1990 전자공학회논문지 Vol. No.

MOCVD에 의하여 초격자 및 HEMT 구조를 성장하고 그 특성을 보고한다. GaAs/AlGaAs의 경우, 주기성(periodicity),계면 급준성, Al 조성 균일성을 경사연마 및 double crystal x-ray 측정에 의하여 확인하였고, 고립 양자우물의 양자효과(quantum size effect)에 의한 PL(photoluminescence) 스펙트럼을 관측하였다. 이 PL FWHM (full width at half maximum)과 우물 두께의 관계로 부터 계면 급준성이 1 monolayer fluctuation 정도인 초격자 구조가 성장되었음을 확인하였다. 한편, HEMT 구조의 경우에 헤테로 계면에 형성된 2차원 전자층의 존재를 C-V profile, SdH(shu-bnikov-de Haas)진동, 저온 Hall 측정을 통하여 확인하였다. 저온 Hall 측정에서 15K에서 sheet carrier density $5.5{\times}10^{11}cm^-2$,mobility $69,000cm^2/v.sec$, 77K에서 sheet carrier density $6.6{\times}10^{11}cm^-2$, mobility $41,200cm^2/v.sec$ 이었다. 또한 quantum Hall effect 측정으로 부터 잘 형성된 SdH 진동 및 quantized Hall plateau를 관측하였다. We developed the technologies of wuperlattice and HEMT structures grown by MOCVD, and their characterization. In the case of GaAs/AlGaAs superlattice, the periodicity, interface abruptness and Al compositional uniformity were confirmed through the shallow angle lapping technique and double crystal x-ray measurement. Photoluminesence spectra due to quantum size effect of isolated quantum wells were also observed. The heterojunction abruptness was estimated to be within 1 monolayer fluctuation by the analysis of the relation between PL FWHM(Full Width at Half Maximum) and well width. HEMT structure was successfully grown by MOCVD. The 2 dimensional electron gas formation at heterointerface in HEMT structure were evidenced through the C-V profile, SdH (Shubnikov-de Haas)oscillation and low temperature Hall measurement. Low field mobility were as high as $69,000cm^2/v.sec$ for a sheet carrier density of $5.5{\times}10^{11}cm^-2$ at 15K, and $41,200cm^2/v.sec$ for a sheet carrier density of $6.6{\times}10^{11}cm^-2$ at 77K. In addition, well defined SdH oscillation and quantized Hall plateaues were observed.

Kinesin-2 comprises two subfamilies of the heterotrimeric or homodimeric motors found in mammalian cells. Heterotrimeric kinesin-2 consists of kinesin superfamily proteins (KIFs) 3A and 3B and kinesin-associated protein 3 (KAP3), which is a molecular motor protein that moves along microtubules. It plays diverse roles in cargo transport, including anterograde trafficking in cilia, and interacts with many different cargoes and proteins, but their binding proteins have not yet been fully identified. In this study, the yeast two-hybrid assay was used to identify the proteins that interact with the cargo-binding domain (CBD) of KIF3A, and an interaction between KIF3A and brain expressed X-linked 2 (Bex2) was found. Bex2 bound to the CBD-containing C-terminal tail region of KIF3A but did not interact with the same region of KIF3B or KIF5A (a motor protein of kinesin-1). KIF3A interacted with another isoform, Bex1, but did not interact with Bex3. In addition, glutathione S-transferase (GST) pull-downs showed that KIF3A specifically interacts with GST-Bex1 and GST-Bex2 but not with GST alone. When co-expressed in HEK-293T cells, Bex2 co-localized with KIF3A and co-immunoprecipitated with KIF3A and KIF3B but not KIF5B. In combination, these results suggest that Bex2 is capable of binding to heterotrimeric kinesin-2 and may serve as an adaptor protein that links heterotrimeric kinesin-2 with cargo.

GaAs 집적회로 제조를 위한 에피 성장 연구

김무성,엄경숙,박용주,김용,김성일,조훈영,민석기,Kim, Moo-Sung,Eom, Kyung-Sook,Park, Young-Joo,Kim, Yong,Kim, Seong-Il,Cho, Hoon-Young,Min, Suk-Ki 한국재료학회 1993 한국재료학회지 Vol.3 No.6

Bulk반절연 기판 웨이퍼에 이온 주입법에 의한 기존의 GaAs집적회로 제작시 발생하는 문제점을 보완하고자 반절연 기판 위에 반절연성의 고저항 GaAs 에피층을 성장하는 연구를 수행하였다. 먼저 반절연 기판의 EPD분포를 조사하고, MOCVD와 MBE법을 이용하여 undeped GaAs반절연성 에피층을 성장시켜 실제 집적회로의 제작에 적합한지를 평가하였다. 평가방법은 반절연성 에피\ulcorner을 buffer층으로 성장시킨 에피 기판에 ungated FET를 제작하여, 이 반절연성 에피\ulcorner을 통한 누설전류를 측정하고, 또한 반절연 기판의 EP분호의 영향을 조사하였다. 누설 전류의 측정결과 비교적 주설 전류가 큰 1$\mu\textrm{m}$ 두께의 MOCVD시료에서도 270nA/mm로 FET의 pinch-off에는 영향을 주지 못하는 매우 작은 누설 전류 값을 나타내었다. 또한 누설전류의 분포가 반절연 기판의 EPD분포와 일치하는 것을 발견하여, 에피층의 quality에 기판의 결함이 미치는 영향을 확인하였다. MBE법으로 성장한 2$\mu\textrm{m}$ 두께의 undoped burrer층 시료는 휠씬 좋은 특성을 나타내었으며, 매우 균일하고 낮은 누설전류(40nA/mm)가 측정되었다. The growth of semi-insulating(SI) high resistant undoped GaAs epilayer has been studied to solve the problems ocurring when GaAs IC is fabricated by the widely used ion implantation directly into the SI GaAs substrate. The EPD ditribution of the SI substrates has been examined, and the suitability of the buffer layers grown by MOCVD and MBE, respectively, has been tested for IC fabrication through leakage current measurement. IJngated FET has been fabricated on the SI epilayer and leakage current through the buffer layer has been measured. In the case of MOCVD grown 1$\mu\textrm{m}$-thick buffer layer, the leakage current is as small as about 270nA/mm, and this value does not affect the pinch-off of FET. In this case, the epilayer quality is affected by the substrate defects because the leakage current distribution is coincided with the EPD distribution of the SI substrate. The 2$\mu\textrm{m}$-thick buffer layer grown by MBE, however, has the better quality, and shows the lower leakage current(40nA/mrn) and higher uniformity.

Effect of inoculation trial on plant height and dry matter yield of seven alfalfa varieties (Medicago sativa L. var. Washoe, Ranger, Lahontan, Narragensett, Atlantic, Vernal, and Moapa 69) which are considered to be well adapted in these areas were conducted during 1973-1974 in a relatively poor soil at the field station in Kyung Hee University. Root nodule bacteria: Rhizobium meliloti (Noculator Northrup Kings Co. Ltd) was applied at a rate to provide 6 oz/30l of alfalfa seeds. Seven varieties were seeded in pots on May 31, 1973 and in second year, they were transplanted in field. 1. Dry matter yield and plant height of all inoculation plots were significantly greater than those of the no inoculation plots in all varieties. 2. In the 1973, dry matter yield of inoculation plot a in pot experiment was in the order of Moapa 69> Vernal> Lahontan> Washoe> Atlantic> Narragensett> Ranger. 3. There was no difference in dry matter yield between with and without-inoculation after transplanted in a field in the second year (1974). Total dry matter yield of varieties was in the order of Washoe> Lahontan> Moapa 69> Ranger> Narragensett> Vernal> Atlantic.

Objectives : A protocol called "critical pathway" was developed to standardize the management of hospital patients the day after they underwent gamma knife radiosurgery. The quality of improvement in patient outcomes was evaluated. Methods : Critical pathway was developed, according to the regulations of the I hospital, by analyzing the medical records of 22 inpatients who underwent gamma knife surgery within the period from January to April 2011 on the day of the surgery. The study included a group of 22 patients admitted to the hospital the day after they underwent gamma knife radiosurgery, between July and September 2011. The control group included 22 patients who had surgery employing the same method within the period from May to June 2011. To measure the effects on quality improvement, the average length of stay, the execution rate of the hospital discharge notice system, daily hospital revenue, and the satisfaction of the patients and the medical team were assessed. The patient questionnaire employed a four-point Likert scale while the medical-staff questionnaire employed a five-point Likert scale. Result : The average length of stay was significantly shorter in the study group compared to the control group (2.3 days vs. 3.8 days, P<0.05). The execution rate of the hospital discharge notice system was higher in the study group (100% vs. 72%) than in the control group. Daily hospital revenues were higher by 264,178 Korean won in the study group when compared to the control group. The study group showed greater satisfaction of patients compared to the control group based on a four-point Likert scale (P<0.05). The study group showed greater satisfaction in medical team compared to the control group based on a five-point Likert scale (P<0.05). Conclusion : The development and implementation of a critical pathway protocol for hospital admission the day after gamma knife radiosurgery is an effective care process that improves the clinical quality.
