The field of modern Korean history had to overcome premodern perspectives and systems of historiography as well as the colonial historiography from the Japanese colonal period. It attempted to discard chronologies and other earlier methods of historiography for narratives that were oriented more towards human relationships where the nation and people were the subject of history. Those peopie the base of modern historical studies were ‘reformed Confucianists’ (kaesin yuhak cha) who were active during the time of the Great Han Empire. Their modern reform theories could be called pyonbop ron(變法論) or legal reform theories. They attempted to modernize by adopting modern political theories that they then applied to a foundation based on traditional culture informed by Confucianism. In this respect,although they were inclined towards complete Westernization, their ideas of modernization differed from other enlightenment theories Their compromise between new learning and old learning, which formed the basis of their reform ideas, also attached great importance to the writing of history. At the time, this system of modern historiography was presented as ‘new history’(sinsa).They pointed out the deficiencies of historical methods as they compiled numerous histories written by Japanese. The Japanese perspective on Korean history permeated these works. Advocates of pyonbop theories who believed in the need for a nationalist approach to historical writing were harshly critical of this aspect and instead turned their focus to the historical studies of sirhak (‘practical learning’) scholars. Critical of Sino-centric approaches to history, they stressed ‘national history’ (kuksa) and carried on a tradition of evidential analysis using primary documents. The kyemong enlightenment movement that unfolded after 1905 was a movement that targeted serf-strengthening and the reclamation of national rights. Although education and industrial development was deemed necessary for self-strengthening, they also emphasized mental and spiritual elements, such as concepts of a fatherland (choguk chongsin), national spirit (kukhon), and national characteristics (kuksu). They attempted to develop national spirit and patriotism through the writing of national history, a kind of historiography that was spearheaded by none other than pyonbop theorists such as Pak Un-sik(朴殷植, 1859-1925), Sin Chae-ho(申采浩, 1880-1936) and others. Criticizing the historical writing that held China in such high esteem, they promoted the importance of national history, with particular emphasis its heroes and historical writing about heroes who triumphed over foreign invasion. By 1910, the limitations to self-strengthening and productivity theories were increasingly apparent, causing a rift within the enlightenment movement itself. Among those, Pak Un-sik and Sin Chae-ho arrived at their own distinct interpretations of the true nature of Social Darwinist theories and the despotic nature of imperialism, and came to view the new citizen (sin kungmin) and the people (kungmin) as the subjects of history. While also pointing out the mistakes of Confucianism, upon which they had been dependant, they instead emphasized Tangun and traditional religions that put forth a new historical paradigm centered on Tangun, Koguryo and Parhae. Actively pursuing such historical research in the 1910s, they presented nationalism in terms of preservation of national characteristics while they groped for new alternatives to the national movement. Into the 1920s, as theories of national spirit and national characteristics were fused together with new concepts, a modern nationalist historiography emerged. Stressing humanism and equality among citizens, they viewed the masses as a solution to the national problem. Even though Pak Un-siks The Bloody History of the Korean Independence Movement(『韓國獨立運動之血史)), written in 1920, continued to advocate national spirit, after World War I and the Russian Revolution, his historical writings focused increasingly on worldwide changes and the issue of nation and the people. Sin Chae-ho also presented a historical theory based on the struggle between the self(我) and the non-self(非我), claiming that indigenous morals was a foreign concept and arguing that the national problem had to be understood from the perspective of the masses. This ultimately formed the foundation of modern Korean historiography.

Reverse electrodialysis (RED) is one of the promising processes for generating electricity from the salt concentration gradient between river and sea water. A RED stack contains alternately arranged anion and cation exchange membranes which separate salt solutions of different concentrations. The power generation performance of RED significantly depends on the characteristics of ion exchange membranes. In this work, we have prepared high performance pore-filled anion-exchange membranes. In addition, the optimization of membrane design parameters has been investigated using the membranes via various electrochemical analyses in terms of the enhancement of RED performances. Finally, the membrane surface has been modified with acid-doped polypyrrole for the improvement of the membrane properties. (No. 10047796) (No. 2015H1C1A1034436)

김도형,윤민홍,이경희,이철훈,Kim, Do-Hyung,Yun, Min-Hong,Lee, Kyung-Hee,Lee, Cheol-Hoon 한국정보처리학회 2008 정보처리학회논문지D Vol.15 No.1
본 논문에서는 음성통화를 위해 CDMA 네트워크와 데이터 통신을 위해 와이브로 네트워크를 동시에 사용하는 최초의 임베디드 리눅스 기반 듀얼모드 응용 서비스인 모바일 이야기꾼의 구현에 대해서 기술한다. 현재 와이브로 상용 서비스와 함께 두 개의 이종 네트워크를 지원하는 단말이 출시되었지만, 이들 네트워크를 효과적으로 사용하여 사용자에게 보다 나은 서비스를 제공할 수 있는 응용 서비스의 개발은 미비한 실정이다. 모바일 이야기꾼은 사용자가 듀얼모드 지원 단말에서 텍스트를 입력하면, 와이브로 네트워크를 통해 인터넷 상의 TTS 서버로 전달한다. TTS 서버는 전달된 텍스트를 음성으로 변환하고, 변환된 음성 데이터를 듀얼모드 지원 단말로 다시 전달한다. 듀얼모드 지원 단말은 수신된 음성 데이터를 CDMA 네트워크를 통해 수신자에게 전송하게 된다. 구현된 모바일 이야기꾼은 주위가 시끄러운 환경이나 언어 장애가 있는 사람도 CDMA를 통한 음성 통화를 가능하게 한다. This paper describes the implementations of the first application service based on embedded Linux; Mobile Teller which uses WiBro network for data communications and CDMA network for voice communications. Currently, with the appearance of WiBro service, dual-mode terminals which support two heterogeneous networks are available. But, the development of applications which effectively use these networks for providing better service to user is rarely prepared. At Mobile Teller, when a sender on a dual-mode terminal types texts, the texts are transmitted to a TTS server located in the Internet through WiBro network. Subsequently, the TTS server converts the texts into voices and transmits the voice data to the dual-mode terminal. At last the dual-mode terminal sends the voice to the receiver through the CDMA network. In case of noisy environment or when a user has difficulty in speaking, Mobile Teller makes voice communication possible

본 논문에서는 음성통화를 위해 CDMA 네트워크와 데이터 통신을 위해 와이브로 네트워크를 동시에 사용하는 임베디드 리눅스 기반의 듀얼모드 응용 서비스인 개인 오디오 레코더의 구현에 대해서 기술한다. 개인 오디오 레코더는 듀얼모드 지원 단말에 탑재된 클라이언트에서 음성 녹음을 시작하면, 송신자와 수신자의 CDMA 음성 데이터가 와이브로 네트워크를 통해 인터넷 상의 저장 서버로 전달된다. 개인 오디오 레코더 서버는 통화 번호 및 통화 시간을 기준으로 음성 데이터를 서버에 저장하게 된다. 구현된 개인 오디오 레코더는 단말의 저장공간이 부족한 환경에서도 음성 통화 내용을 저장할 수 있도록 한다. 그리고, 개인 오디오 레코더는 서버에 저장된 통화 목록을 검색하여, 특정 통화 내용을 재생할 수 있다. This paper describes the implementations of the application service based on embedded Linux; Personal Audio Recorder (PAR) which uses WiBro network for data communications and CDMA network for voice communications. At PAR, when PAR client starts voice recording on a dual-mode terminal, the CDMA voice data of caller and callee is transmitted to storage server located in the Internet through WiBro network. Then, PAR server stores voice data on storage server according to the call number and call time. In case of shortage of storage space on terminal, PAR makes user to store voice data. And, PAR can search a catalog of stored data on server and play the specific content.

This paper describes the design and implementation of Personal Mobile Broadcasting Service which bases on embedded Linux and it supports personal broadcasting in wireless network environments. Recently, with the advent of various wireless networks and the increased use of high performance mobile devices, the demand for personal mobile broadcasting is being increased. The personal mobile broadcasting service makes it possible that mobile users create contents using their own mobile devices while they are moving or they are in any place. And then, it sends the created contents to server in real-time where their blogs are. Users connected to the content creator's blog can play the contents in real-time. With the implemented personal mobile broadcasting service, mobile users can share multimedia contents in real-time through wireless networks. And, it also helps users to construct their own broadcasting stations where they can broadcast the scene of the accident or public performance in real-time.
2015 개정 초등 사회과(역사영역) 5·6학년 교과서 서술 오류 및 현대 정치사 내용 분석
김도형 이화여자대학교 교과교육연구소 2020 교과교육학연구 Vol.24 No.3
This paper analyzes the descriptions and descriptions of political history seen in the 2015 revised elementary society and the 5th and 6th grade history areas. It is to solve two problems through textbook analysis. First, the analysis of social studies and history areas in the 5th and 6th grades showed that many revisions of descriptions took place. However, a number of descriptive errors were also found in later published textbooks. In this regard, we want to reveal the details of the narrative error and prevent students from being educated with wrong historical facts. In the description of modern political history, we found that 'democracy' can only be interpreted as a 'democratic movement history'. Therefore, we would like to help elementary school history classes by analyzing and presenting the problems of narrative errors and political history descriptions that are seen in social science and historical descriptions. 본 논문은 2015 개정 초등 사회과 5·6학년 역사영역에서 보이는 서술 오류와 현대 정치사 서술을 분석하고, 분석결과에서 드러난 문제점을 해결하는 것을 목표로 한다. 두 가지 문제점은 다음과 같다. 첫째, 5·6학년 사회과 역사영역을 분석한 결과 많은 내용에서 서술 수정이 일어났음을 알 수 있었다. 그러나 이후 출판된 교과서에서도 여전히 서술 오류가 다수 발견됨을 확인하였다. 이에 서술 오류에 대한 구체적인 내용을 밝히고, 이를 통해 학생들에게 잘못된 역사적 사실이 교육되는 것을 방지하고자 한다. 둘째, 현대 정치사 서술에서 ‘민주주의’가 ‘민주운동사’라는 의미로만 해석될 수도 있다는 점을 발견하였다. 따라서 사회과 역사영역 서술에서 보이는 서술 오류와 정치사 서술에 대한 문제점을 시론적으로 분석·제시하여, 초등학교 역사 수업에 도움을 주고자 한다.
Analysis of Delayed Postpolypectomy Bleeding in a Colorectal Clinic
김도형,임석원 대한대장항문학회 2011 Annals of Coloproctolgy Vol.27 No.1
Purpose: The colonoscopic polypectomy has become a valuable procedure for removing precursors of colorectal cancer,but some complications can be occurred. The most common complication after colonoscopic polypectomy is bleeding,which is reported to range from 1% to 6% and which can be immediate or delayed. Because the management of delayed postpolypectomy bleeding could be difficult, the use of preventive technique and reductions of risk factors are essential. Methods: From January 2007 to December 2008, delayed hemorrhage occurred in 18 of the 1,841 polypectomy patients examined by one endoscopist. These cases were reviewed retrospectively for risk factors, pathologic findings, and treatment methods. Results: Delayed bleeding occurred in 18/1,841 patients (0.95%). The mean age was 55.9 ± 10.9 years, and the male-to-female ratio was 8:1. The most common site was the right colon (11 cases, 61.1%), and the average polyp size was 9.2 ± 2.8mm. Delayed bleeding was identified from 1 to 5 days after resection (mean, 1.6 ± 1.2 days). The most common macroscopic type of polyp was a sessile polyp (10 cases, 55.6%), and histologic finding was a tubular adenoma in 13 cases (72.2%). Seventeen cases were treated with clipping for hemostasis and 1 case with epinephrine injection. Conclusion: The right colon and a sessile polyp were associated with an increase in delayed postpolypectomy bleeding. Reducing risk factors and close observation were essential in high risk patients, and prompt management with hemoclips was effective.
