For the purpose of understanding Wang-bing's idea, which was influenced by Taoism and Hyeon-hak(玄學), I investigated the quotations of Taoism Books such as Jang-ja(莊子) in the Hwangje-Naegyeongsomunju(黃帝內經素問注), and came to the following conclusions. In the process of writing notes on the Hwangje-Naegyeongsomun, Wang-bing quoted Taoism Books such as Jang-Ja 10 times at 8 passeges which suggest the idea of Hyeon-hak. Through this annotating process, he suggested the vision of the Hyeon-hak idea which pursued the harmony of system and human nature. In the process of the annotating, he expressed the way of sage who practicing the caring of one's own health. And he emphasized on body and perfectly preserving of nature of oneself. Wang-bing especially emphsized on cultivating of one's mind while he insisting one's human nature. This means he pursued one's nature under the actual system, which was different from general Taoism. It was Hyeon-hak idea. So we can interpret Wang-bing as a sucessor of Hyeon-hak philosophers of Wi-Jin(魏晋) period.

This study is focused on the modeling of two phase fluid flow system in the electrode of hydrogen gas generator. The characteristics of hydrogen gas generation was studied in view of efficiency of hydrogen gas generation rate and a tendency of gas flow through the riv of electrode. Since the flow rate of generated gas is the most crucial in determining the efficiency of hydrogen gas generator, we adopted the commercial analytical program of COMSOL $Multiphysics^{TM}$ to calculate the theoretical flow rate of hydrogen gas from the outlet of gas generator.

This study is focused on the channel design of bipolar plate in the electrode of hydrogen gas generator. The characteristics of hydrogen gas generation was studied in view of efficiency of hydrogen gas generation rate and a tendency of gas flow through the riv design of electrode. Since the flow rate and flow pattern of generated gas in the two phase flow system are the most crucial in determining the efficiency of hydrogen gas generator, we adopted the commercial analytical program of COMSOL MultiphysicsTM to calculate the theoretical flow rate of hydrogen gas from the outlet of gas generator and flow pattern of two phase fluid in the electrode. In this study, liquid electrolyte flows into the bipolar plate and decomposed into gas phase, two phase flow simulation is applied to measure the efficiency of hydrogen gas generation.

서버 정보를 수집해 네트워크 지도를 구축하는 작업은 쉽게 발생하는 보안 사고들을 예방할 뿐만 아니라, 사이버전에 대비하고 적절한 정책을 제안하는데 방향을 제시해준다. 본 논문에서는 기존의 네트워크 스캐너인 Nmap과 ZMap을 분석하고, 네트워크 지도를 만들기 위해 서버 정보를 수집하는 기술로 배너 그래빙(banner grabbing)을 사용했다. 실시간으로 서버 정보를 수집하는 크롤링 도구를 구현하면서 정보 수집 대상이 받는 부하를 줄이기 위해 주소 생성 방식을 고안하고, 속도 향상을 위해 스레드를 나눴다. 구현한 크롤링 도구를 자체적으로 제시한 성능 평가 기준에 따라 기존 네트워크 스캐너를 사용하는 경우와 비교했다. 마지막으로, 크롤링 도구를 활용해 국내외 서버에서 정보를 수집한 DB를 바탕으로 국가별 위험 지표를 도출했으며 국가마다 차이는 있으나 수많은 사용자들이 위험한 공격에 노출되어 있는 실태를 확인했다.
