본 연구에서는 17세기 병자호란시 호지(胡地)에 피로되었던 조선 백성의 피로담을 통해 전쟁과 백성의 삶에 대해 살펴보고자 하였다. 평민 김승경과 안추원은 어린 나이에 몽고 북경으로 포로로 끌려가 27년간 포로생활을 하다가 조선으로 탈출해 왔다. 김승경과 안추원은 전쟁으로 인해 뒤틀린 자신의 삶을 되돌려 놓기 위해 도망을 선택하였다. 탈출에 성공한 김승경은 고향에 가족들이 생존해 있어 별 어려움 없이 생활할 수 있었지만, 안추원은 가족의 생사조차 파악할 길이 없었고 그에게 정신적 경제적 지원을 해줄 곳은 어디에도 없었다. 그는 다시 북경으로 탈출을 시도하다 발각되어 청과의 외교문제를 일으키게 되었다. 김승경 안추원의 이야기는 역경에 굴하지 않고 자신의 삶을 강한 의지로 극복하려고 했던 조선 백성들의 삶을 보여준다. 피로체험은 피로인 당사자들에게는 기억하기 싫을 정도로 끔찍한 경험이었겠지만, 이들에 의해 전해진 이국 문화와 풍습은 당대인들에게 새로운 세계에 대해 눈 뜨게 하는 기회가 될 수 있었다. 당시 조선 조정은 피로인의 수나 실태조차 제대로 파악하지 못할 정도로 무기력한 상태에 있었다. 그러나 도망포로를 청으로 돌려보내야하는 송환규정을 어기고 자국민 보호를 위해 아주 최소한의 의무를 다하고 있었다. 조선 백성의 피로체험담을 통해 자주적인 역사를 펼쳐나가지 못한 17세기 조선사회와, 망각의 그늘 속에 가려져 있는 현대사의 전쟁포로 문제 등에 대해 반추할 수 있을 것이다.

A signal system for improving the code acquisition complexity of Global Navigation Satellite System (GNSS) receiver is proposed and the receiving correlator scheme is presented accordingly. The proposed signal system is a hierarchical code type with a duplexing configuration which consists of the Zadoff-Chu (ZC) code having a good auto-correlation characteristic and the Pseudo Random Noise (PRN) code for distinguishing satellites. The receiving correlator has the scheme that consists of the primary correlator for the ZC code and the secondary correlator which uses the PRN code for the primary correlation results. The simulation results of code acquisition using the receiving correlator of the proposed signal system show that the proposed signal scheme improves the complexity of GNSS receiver and has the code acquisition performance comparable to the existing GNSS signal system using Coarse/Acquisition (C/A) code.

1. Objectvies The study is purposed to find the role of the six-channels of shanghan(傷寒六經) on the relation between ${\ulcorner}$Dongyisusaebowon(東醫壽世保元)${\lrcorner}$ and ${\ulcorner}$Shanghanlun(傷寒論)${\lrcorner}$ 2. Methods The study is compared ${\ulcorner}$Euiwonleun(醫源論)${\lrcorner}$ with the process of study on the ${\ulcorner}$Shanghanlun(傷寒論)${\lrcorner}$, origin and theorys of the Shanghan six-channels(傷寒六經). 3. Results and Conclusions Just as Dong-mu fully understood the concepts of ${\ulcorner}$Shanghanlun(傷寒論)${\lrcorner}$ through the six of Shanghan(傷寒六經) proposed by Chu-gueng(朱肱), the ideas of Differential Diagnostic System(辨證體系) of ${\ulcorner}$Shanghanlun(傷寒論)${\lrcorner}$ had much influence on ${\ulcorner}$Dongyisusaebowon(東醫壽世保元)${\lrcorner}$. Therefore a new medical theory could be born.

Objective : This study was carried out to review Chang-Won Lee's theory of Sasangand acupuncture of constitution. Methods : We have investigated Chang-Won Lee's unknown literature "Medicine of sassang "(四象醫學). Results : Constitutional acupuncture is based on the diversity of human being and medically developed the response variation to disease and acupuncture. The diversity is due to the Organ's Congenital Formation Variation based on human nature and it is categorized as four from physiology, pathology, symptoms, to therapy. Chang-Won Lee's constitutional acupuncture discriminated constitution of comparison palpations of right and left both sides. He insisted that constitution only four type(Sasang), not exist man of To-Hyoung (土形人) in "young -chu"(靈樞) and his constitutional acupuncture all used Jung-kyuck (reinforcement acupuncture method) and Seong-kyuck(reducing acupuncture method) of Sa-am(舍岩)

Highlighted is significance of the floating slab track for mitigating vibrations induced by train, together with the recent trends towards speed-up of railways. In the design of the floating slab track, it is more beneficial to increase the slab length since a significant impact can be induced on the train and track at the discontinuous points between slabs with the finite slab length. However, if the slab length is too long, the tensile stress of slab concrete and the additional stress on rail due to the temperature change and shrinkage of concrete slab. Thus it is of great importance to relevantly determine the slab length. In this study, to understand these phenomena and establish the countermeasures, the dynamic behaviors of train and track at the inter-slab discontinuous points have been explored and the effect of dowel joints as one of countermeasures has been analytically investigated.

The Rapid Prototyping (RP) technology has advanced in many application areas. In this research, two different types, cylinder and scaffold, of implantable Drug Delivery System (DDS) were fabricated using Nano Composite Deposition System (NCDS), one of the RP systems. The anti-cancer drug (5-fluorouracil, 5-FU), biodegradable polymer (PLGA(85: 15)), and bio ceramic (Hydroxyapatite, HA) were used to form drug-polymer composite material. Both types of DDS were evaluated in vivo environment for two weeks. For evaluation, the cumulative drug release and shape stability were measured. Test results showed that the scaffold DDS provide higher cumulative drug release and has better stability than cylinder DDS.

The trend of miniaturization has been applied to the research of rockets to develop prototypes of micro rockets. In this paper, the development of a web-integrated prototyping system for three-dimensional micro rockets, and the results of combustion tests are discussed. The body of rocket was made of 6061 aluminum cylinder by lathe process. The three-dimensional micro nozzles were fabricated on the same aluminum by using micro endmills with ${\phi}100{\mu}m{sim}{\phi}500{\mu}m$ diameter. Two types of micro nozzle were fabricated and compared for performance. The total mass of the rockets was 7.32 g and that of propellant (gun powder) was 0.65 g. The thrust-to-weight ratio was between 1.58 and 1.74, and the flight test with 45 degree launch angle from the ground resulted in $46\;m{\sim}53\;m$ of horizontal flight distance. In addition, ABS housing for the micro machined rocket was fabricated using Fused Deposition Modeling (FDM). A web-based design, fabrication, and test system for micro nozzles was proposed to integrate the distributed hardware resources. Test data was sent to the designer via the same web server for the faster feedback to the rocket designer.
