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.

To collect server information and construct network map enable us to prevent security breach, prepare for national cyber warfare and make effective policies. In this paper, we analyze well-known network scanners, Nmap and ZMap, and construct network map using banner grabbing. We use multiple threads in order to increase scanning speed and arrange IP lists by specific order to reduce the load on information gathering targets. Also, we applied performance tests to compare the real-time banner grabbing tool with the existing network scanners. As a result, we gathered server information from domestic and overseas servers and derived a risk index based on the collected database. Although there are slight differences among countries, we can identify the risky situation that many users in every country are exposed to several security breaches.
