This report describes 90 prescriptions related to the use of Platycodi Radix main blended from Dongeuibogam. The following conclusions were reached through investigations on the prescriptions that use Platycodi Radix as a key component. Prescriptions that Platycodi Radix was taken as a monarch drug are utilized for 30 therapeutic purposes, for example, cough disease, throat disease, abscess and pus, and wind disease. In particular, 12.1% of prescriptions appear in the chapter of cough, and 9.9% of those appear in the chapter of throat, and each 8.8% of those appear in the chapter of abscess and of wind disease. Prescriptions that utilize Platycodi Radix as the main ingredient are used in the treatment of cough disease, throat disease and abscess, and they are also used for treating 74 different types of disease. The prescriptions are compounded with Platycodi Radix as a monarch drug are related to exogenous agents such as wind-cold pathogen, wind-heat pathogen, epidemic diseases, and endogenous agents such as seven emotions, and non-endo-exopathogenic factors like excessive labor, deficiency of Qi and blood, phlegm-mass, phlegm-fire, ect. The dosage of Platycodi Radix is 2pun(about 0.75g) to 1nyang(about 37.5g), however 1don (about 3.75g) has been taken the most for clinical application. We can find out that according to herbs or prescriptions blended with it self, Platycodi Radix makes a variety of functions to penetrate lung stagnancy and remove phlegm, relieve throat pain and get rid of pus, and regulate Qi flow. And Gamgiltang is the most useful base prescription which used the Platycodi Radix as the main component.

The HEMU-400X(High-speed Electric Multiple Unit 400km/h eXperiment) project starts in 2007. It is required to control and balance the systems engineering activities throughout the project life cycle for a successful completion of the project. The Systems Engineering Management Plan(SEMP) is the primary, top level technical management document for the integration of all engineering activities within the context of, and as an expansion of, the project plan. A SEMP should be prepared for each project and regularly updated as development progresses. This paper proposes the systems engineering management plan for the HEMU-400X project.

In the Core Technology R&D of the defence area, the development of the related core element technology could be the foundation to develop advanced weapon system in the future. But it might make various problems if you can not accurately define the TRL of the element technology. In other words, if the technology is not sufficiently mature and then the project starts, it might require an increase in the development period and additional cost. Finally the system will be in an incomplete state and result in user dissatisfaction and the project failure. Therefore it is a very important task to properly assess the TRL for a successful project. In this study, We propose the method for risk management of core technology R&D project of the defence area using the QFD process with degree of difficulty and technology readiness level. It is also presented the process to determine the risk level using TRL and Degree of difficulty. Finally We apply this method to UGV system for verifying the result of this study.

스테비아(Stevia rebaudiana Bertoni)는 남미가 원산지인 국화과의 감미식물이다. 스테비아추출물 발효액으로부터 세균 23균주와 효모 10균주를 분리하여 일반적인 분류학적 방법과 분자유전학적 방법으로 동정하였다. 스테비아추출물 발효액에서 분리된 균주들은 5속 10종의 세균과 1종의 효모균에 속하는 것으로 나타났다.16S와 18S rDNA 염기서열 분석에 근거하여 계통수를 작성하였다. 분리균들의 항미생물 활성을 여러 세균과 식물병원성 진균들에 대해 조사하였다. 분리균들 중에서는 Lactobacillus paracasei SB13이 광범위한 세균들에 대해서 강한 항균활성을 나타내었다. 이들 결과는 토양개량을 위한 친환경적 미생물 제제를 개발하는데 도움을 줄 것이다. Stevia rebaudiana Bertoni is a sweet herb of the Asteraceae family originally derived from South America. Twenty three bacterial strains and ten yeast strains were isolated from fermented Stevia extract and identified by general taxonomic methods and molecular genetic method. Isolated strains from fermented Stevia extract include ten species of bacteria which belong to five genus and one species of yeast. Based on 16S and 18S rDNA sequence analysis, phylogenetic trees were constructed. Antimicrobial activity of the isolated strains was examined against various bacteria and plant-pathogenic fungi. Among them, Lactobacillus paracasei SB13 showed strong antibacterial activity towards a wide range of bacteria. These results may be useful to develop environmentally friendly microbial agent for soil improvement.

체내 통신을 이용한 신경 보철용 원격 통신 시스템

Intra-body communication' is a wireless communication technology that uses a body as a transmission medium for electrical signals. Generally, an 'earth ground' is used to create an electric field for operating the system; however this operating method could not apply to telemetry for implanted neural prosthetic devices. So this paper suggests a newly designed intra-body communication for neural prosthetic devices. A floating system which has a couple of electrodes with body was studied to remove an influence of the 'earth ground'. We found that 10MHz is the most suitable carrier frequency in skin experiments and over 3MHz in subcutaneous experiments. The system has been applied to a current stimulator circuit for cochlear implant that uses pulse width modulation (PWM) method at 480kbps rate successfully. 체내 통신은 인체를 통신 매체로 하여 신호를 전송하는 무선 통신 방식이다. 체내 통신 방식은 체내와 송수신 시스템 그리고 외부 접지를 통한 하나의 전류 패스를 형성함으로써 이루어지는데, 인공 와우와 같은 신경 보철 장치의 경우 피하에 이식되어 있기 때문에 외부 접지를 사용하기 어렵다. 따라서 본 논문에서는 이와 같은 접지의 영향을 받지 않는 체내 통신을 제안하여 신경 보철 장치를 위한 시스템을 개발하였다. 개발된 시스템은 이식된 보철 장치의 체내에 위치한 전극으로의 신호 전송이 가능하도록 설계되었다. 효과적인 통신을 위하여 실험동물의 피부 위 실험 및 피하 실험을 통해 신호 전송 특성을 조사하였으며, 피부 위 실험의 경우 약 10MHz, 피하 실험의 경우 약 3MHz 이상의 주파수 대역에서 최대 전송 이득을 가지는 것을 확인하였다. 본 시스템은 데이터 전송률 480kbps를 갖는 pulse width modulation (PWM) 방식을 사용한 인공 와우용 내부 전류 자극기에 적용하여 그 성능을 입증하였다.

It has been proposed that the Cao-$SiO_2$ binary system can be good basic composition of bioactive glasses and glass-ceramics. In the present study, various kinds of Cao-$SiO_2$ gels were prepared by sol-gel method in order to control the microstructure which are related to their dissolution rate, induction period of apatite formation in body environment. Characterization of the gels were done by wet chemical analysis, SEM observation, FT-IR spectroscopy and XRD. The gelation time decreased with CaO content. However, the volume of all the dried gel decreased to 50% of the wet gels irrespective of increasement of CaO content. All the Cao-$SiO_2$ gels were amorphous and contained a large amount of silanol groups on their surfaces after heat treatment up to $800^{\circ}C$. The interconnected structure of the gel changed to agglomerated spherical powders when Ca content exceed to 20 mol%. Most of the Cao-$SiO_2$ gel showed amorphous when heat-treated up to $900^{\circ}C$. However, quartz and cristobalite was produced when heat-treated at $1000^{\circ}C$ and resultant microstructure of the gel contained microporous structure.

해방 이후 한의학의 현대화 논쟁 - 1950년대와 1990년대 이후의 논의를 바탕으로 -

Objectives : The inclusion of Korean Medicine in the national health care system led to the need of a serious discussion on its modernization. This paper looked at how these discussions were progressed. Especially, a difference in the meaning of 'science' in the 1950s and the 1990s was observed. Methods : Articles related to the medical dispute between Korean and Western Medicine in "EE LIM", especially the ones from the 1950s, were selected, classified and analyzed. Research papers on Evidence-Based Medicine were also analyzed. Evidence-Based Medicine was a new medical research methodology in the 1990s. Articles on Evidence-Based Medicine were searched and selected from journal databases: DBpia, KISS, RISS, and OASIS. Results : The problem of establishment of modernity of Korean Medicine in the recent times was addressed in the context of scientification and systematization. Accordingly, the academic societies of Korean Medicine aimed for scientification. But efforts to secure the identity of Korean Medicine opposed to western science were also made. Meanwhile, Evidence-Based Medicine established in 1992 presented a different concept of science. This led to a new means of acknowledgement of Korean Medicine in the modern society. Conclusions : The modernization process of Korean Medicine up to now was a course of scientification. But as this process did not fully reflect its characteristics, the modernization of Korean Medicine still remains a pending question. A modern study methodology that fully reflects the identity of Korean Medicine needs to be established.
