The effects of the conditions of the collector formation on electrical characteristics of the packaged SiGe hetero-junction bipolar transistors (HBT) were investigated. While the DC characteristics of SiGe HBTs such as IV characteristic, forward current gain, Early voltage, and breakdown voltage were hardly changed after packaging, the AC characteristics such as $f_{\tau}\; and\; f_{max}$ were degraded severely. With the rise of the collector concentration, the break-down voltage decreased but the $f_{\tau}$ increased. Additionally, $\beta$ and $f_{\tau}$ values were kept high in the range of elevated collector current due to the increase of the critical current density for the onset of the Kirk effect. The devices As implanted before the collector deposition showed lower breakdown voltage and higher $f_{\tau}$ than the others, which seems to be originated from the As up-diffusion resulting in the thinner collector.

1. Background and purpose: The purpose of this study is to find the characteristic of "Donguisasangshinpyun" through comparison and analysis of "Donguisusebowon" and "Donguisasangshinpyun". 2. Methods: First we compare the composition of Sasang prescription with the same name in "Sinchukbon" and "Gabobon" to the composition of Sasang prescription in "Donguisasangshinpyun" "Donguisasangshinpyunchebang"(東醫四象新編劑方). And we compare the difference of "Donguisusebowon" and "Donguisasangshinpyunchebang" about symptom of Sasang prescription. The third is to find the utilization of Sasang prescription in "Donguisasangshinpyun" "Donguisasangyongyakhuebun"(東醫四象用藥彙分). 3. Results and Conclusions: 1) There are some Sasang prescriptions with the same name in "Donguisasangshinpyunchebang", "Sinchukbon" and "Gabobon". The composition of Sasang prescription in "Donguisasangshinpyun" is based on "Sinchukbon" better than "Gabobon". 2) The symptom of Sasang prescription in "Donguisasangshinpyunchebang" are more various than the symptoms in "Donguisusebowon". We find new symptom of Sasang prescription in "Donguisasangshinpyun" that does not exist in "Donguisusebowon". 3) The Sasang prescription of "Sinchukbon" is utilized much more than the Sasang prescription of "Gabobon" in "Donguisasangyongyakhuebun".

최근 모바일 환경은 스마트폰의 확산에 따라 가히 혁명적인 변화를 가져오고 있으며, 이제 이동통신서비스 시장은 기존 음성 서비스 중심에서 데이터 서비스 중심으로 이동하며, 사용자 중심의 콘텐츠가 서비스의 경쟁력을 좌우하는 소위 2.0 시대에서의 새로운 비즈니스 환경을 요구하고 있다. 특히, 웹을 기반으로 하는 유무선 통합모바일 서비스는 많은 가능성을 시사하면서 새로운 가치를 만들어내고 있다. 이미 모바일 웹 기술은 과거 단순 브라우징 기술을 넘어 다양한 응용 서비스 제공을 위한 웹 기술로 확장되고 있으며, 본격적인 플랫폼으로서의 기능을 제공하는 수준으로 발전되고 있다. 본 고에서는 최근 이루어지고 있는 차세대 모바일 웹 표준화를 중심으로 주요 이슈 및 표준화 동향을 분석하고 나아가 대응전략을 모색하고자 한다.

1. Objective: This study is about a Soyangin patient with vertigo after subarachnoid hemorrhage. In this study, we report the effects of Sasang constitutional treatment to this patient. 2. Methods: This patient was treated by Soyangin's constitutional medications and acupunture according to the result of Sasang constitutional diagnosis. 3. Results and Conclusions: This patient's chief complaints were vertigo and gait disturbance. By using Yangkyuksanhwa-tang mainly, she showed positive response about her symptom. This study shows that Yangkyuksanhwa-tang has effect to vertigo in Soyangin.
