The formation process of Dasan(茶山)'s Yi Xue(易學) in Xinghuxuepai(星湖學派) was examined. Dasan(茶山)'s Yi Xue(易學) succeeded to the methods of Huti (互體) and Yaobian(爻變) from Seong-ho(星湖) and Ha-bin(河濱), and Dasan(茶山) thought that he couldn't cover Zhouyi("周易") just with this one method. So he suggested the four methods called Yilisifa(易理四法), and supplemented it with 18 methods through Duyiyaozhi(?讀易要旨?). Accordingly, the process of how Dasan(茶山)'s Yi Xue(易學) was established was examined one by one. Dasan(茶山) succeeded to the method of Huti(互體) from Seong-ho Lee Ik(星湖李瀷), the leading master of Xinghuxuepai(星湖學派). Nevertheless, Dasan(茶山) argued that the method of Huti(互體) had been from Zhu Xi(朱子). However, this argument of Dasan(茶山)'s seems to have resulted from Zhengzu(正祖)'s academic research policy. As a way to interpret Zhouyi(?周易?), Dasan(茶山) succeeded to the method of Yaobian(爻變) from Ha-bin(河濱). However, Dasan(茶山) argued that Yaobian(爻變)was Zhu Xi(朱子)'s intention. He had no choice but this because of Zhengzu(正祖)'s academic research policy. Dasan(茶山) succeeded to the method of Huti(互體) from Seong-ho(星湖) and Yaobian(爻變) from Ha-bin(河濱), but Dasan(茶山) proposed the four key methods called Yilisifa(易理四法). Many researchers have argued that, as for Dasan(茶山)'s modern viewpoint, Dasan(茶山) developed Yi Xue(易學) in a similar way as Xihe Mauqiling(西河 毛奇齡). However, this viewpoint cannot be judged to have been similar as it was expressed when Dasan(茶山) himself criticized Xihe(西河)'s Jingxueguan(經學觀).

High speed electric trains have nonlinear loads including converters and inverters for the control synchronous motors. Harmonic field measurements have shown that the harmonic contents of a waveform varies with time. Direct application of the harmonic assessment to the snapshot measurements would result in ambiguous conclusions depending on which instant is sampled. A cumulative probabilistic approach is the most commonly used method to solve time varying harmonics. This paper provides an in depth analysis on harmonics field measurement of the high speed electric train loads, harmonics assessment by the international harmonic standards IEC 61000-3-6 and IEEE Std. 519-1992, and harmonics simulation using EDSA program for the case study.

This paper focused on studies of Noneo Jilseo("論語疾書") written by Lee Ik, also known as his honored name, Seong Ho(星湖). Seong Ho(星湖) also had left 10 types of exegetical commentary other than Noneo Jilseo("論語疾書"). The reason for choosing Noneo Jilseo("論語疾書") was that the teachings of Kongzi(孔子) were contained in Noneo("論語"). Also when we understand the Analects of Kongzi(孔子) correctly, we will be able to understand other Confucian Canons accordingly. Seong Ho(星湖) recommended Zhuzi(朱子) pronounced Noneo Jipju ("論語集註") as a critical commentary on the Analects. That is because there are no writings that had considered pupils' opinions and all of the various situations as much as Noneo Jipju ("論語集註"). For this reason, Noneo Jipju ("論語集註") could play a role as an excellent text. However, it is not just quality of the book that matters. While reading the main body, there is an author's comment, saying "For now, I write down my skeptical point of view." With this short note, the author expressed that "Collected Annotation on the Analects" was not necessarily the best teaching. This is the consequence of 'doubt.' We should be skeptical about the Analects of Confucius. That is not to say that the Analects are unconditionally bad. Seong Ho(星湖) expounded that the beginning students should regard Noneo Jilseo("論語疾書") as their textbook, but do not cling only to the disciplines elucidated in the book. Seong Ho(星湖) had written Noneo Jilseo("論語疾書") in order to help people to understand Confucius correctly. Although this book was written during his early professional years, Seong Ho(星湖) had grasped the essence of teaching precisely. Then, what is the essence? That is 'Doubt.' Innate factors therein can be correctly understood through 'Doubt.' In this context, Seong Ho(星湖) had made such comment as "For now, I write down my skeptical point of view." To understand the opinions of Confucius correctly, this process that being doubtful about the text is necessary. The Analects of Confucius are just similar to a coded message. To know accurately about the code, it is necessary to start from 'Doubt' at the first. Such a "Doubt" shall be a key to decrypt the coded messages further.

Graphene, a single atomic layer of sp2-bonded carbon, shows substantial potential for various applications. Chemical manipulation of its electronic properties will be of great importance. In this study, we have investigated interaction between graphene and organic molecular layer of tetrafluorotetracyanoquinodimethane (F4-TCNQ), a strong electron acceptor. F4-TCNQ films of varying thickness were evaporated onto graphene mechanically exfoliated on SiO2/Si substrates. F4-TCNQ molecules increase the frequencies of Raman G and 2D bands of graphene while decreasing the linewidth of G band and 2D/G intensity ratio, which is consistent with increase of hole density in graphene. These results exemplify the possibility of chemical tuning of electronic properties of graphene.

Personal Robot System in developing, have a module architecture, each module are connected through variety network system like ethernet, WLAN (802.11), IEEE 1394 (firewire), bluetooth, CAN, or RS-232C. In developing personal robot system. We think that the key of robot performance is interoperablity among modules. Each network protocol are well connected in the view of network system for the interoperability. So we make a bridging architecture that can routing converting, and transporting packets with matching each network's properties. Furthermore, we suggest a advanced design scheme for realtime / non-realtime and control signal (short, requiring hard-realtime) / multimedia data (large, requiring soft-realtime).

We successfully developed a-Si TFT controlled active matrix cathode (AMC) with gated Mo emitters. Also, we could remove emitter failures of the AMC through a novel surface treatment of Mo-tips, which indicates reduction of $MoO_3$ or chemical wet etching of $MoO_3$ by surface treatment. Transient behaviors of the AMC are strongly dependent on not only DC characteristics of device but also the device structure. Brightness and gray scale were well realized by low-voltage scan and data signals addressed to a-Si TFTs.
