이철원,임인칠,Lee, Chul-Won,Lim, In-Chil 대한전자공학회 1996 전자공학회논문지-B Vol.b33 No.1
본 논문에서는 이산 은닉 마코프 모델(Discrete Hidden Markov Model)을 이용한 연결 음성 인식에 관한 알고리듬 및 모델 토폴로지를 제안한다. 제안된 모델은 인식률과 인식할 수 있는 어휘를 고려하여 2 음소열 및 3 음소열 모델을 사용하며, 보다 정확한 음소 간의 세그멘테이션과 알고리듬의 수행 속도를 고려하여 2 음소열에서는 첫 번째 상태와 마지막 상태를 안정 상태, 나머지 상태는 천이 상태인 4 개의 상태를 갖도록 하고, 또한 3 음소열에서는 7 개의 상태를 갖도록 하며, 여기서 7개의 상태는 3 개의 안정 상태와 4개의 천이 상태를 갖도록 개선한다. 또한, 제안된 음성 인식 알고리듬은 인식 과정 내에서 음소의 발음 구간을 검출하도록 설계한다. This paper proposes an algorithm and a model topology for the connected speech recognition using Discrete Hidden Markov Models. A proposed model uses diphone and triphone model which consider the recognition rate and recognisable vocabulary. Considering more exact inter- phoneme segmentation and execution speed of algorithm, 4 states have to exist in diphone model where the first state and the last state are keeping a steady state, the other states hold a transient state. 7 states have to exist in triphone model where 7 states are specified and improved to 3 steady states and 4 transition states. Also, the proposed speech recognition algorithm is designed to detect the inter-phoneme segmentation during the recognition processing.

Technology Sourcing Strategies and Cooperative Patterns in Vertical Cooperative R&D Projects
이철원 ( Chul Won Lee ),배종태 ( Zong Tae Bae ) 기술경영경제학회 1995 Journal of Technology Innovation Vol.3 No.1
Since 1982, the government of Korea has actively promoted vertical cooperative R&D programs between government-sponsored research institutes (GRIs) and private firms. A number of firms participated in the programs because cooperative R&D could lower the risk and could contribute to rapid commercialization of many technologies. This paper examines the effectiveness of vertical cooperative R&D projects by the modes of cooperation between GRIs and industrial firms, and analyzes the performance of participating firms` technology sourcing strategies for commercial utilization of cooperative R&D results at the project level. The data have been obtained from 128 cases of vertical cooperative R&D projects performed from 1982 to 1989 under the Government-Industry Cooperative R&D Program sponsored by the Ministry of Science and Technology(MOST) in Korea. The cooperative R&D projects are classified into 4 groups by two criteria, i. e. , the level of participation of firms, and the breadth of cooperation. The findings suggest that firms should actively participate in cooperative R&D projects. In addition, in order to enhance commercial success, cooperation between GRIs and industrial firms should not be limited to R&D stage only. The breadth of cooperation should be extended to commercialization stage. Small- and medium-sized firms participating in vertical cooperative R&D projects in Korea usually lack internal technological capabilities that are needed to commercialize the results of cooperative R&D. Three different technology sourcing strategies exclusive cooperative R&D strategy, in-house development augmented cooperative R&D strategy, and licensing-in supplemented cooperative R&D strategy - are empirically derived through cluster analysis of the relative usage rates cooperative R&D and of other supplementary technology acquisition methods. The findings suggest that the firms participating in vertical cooperative R&D projects should try to utilize other supplementary technology acquisition methods in order to achieve commercial utilization of the vertical cooperative R&D results.

洋務運動시기의 경제체제변화는 생산양식의 전화를 의미한다. 즉 봉건주의 소농경제와 수공업의 공업체제에서 자본주의 기계제공장기업의 등장으로 대량생산이 도입되는 과정이었다. 이처럼 자본주의 생산양식의 전화는 궁극적으로 봉건주의 전제정치와 봉건경제체제의 와해를 전제로 시작되었으며 양무운동의 초기 지향점이자 관심사였던 봉건통치질서인 정치체제의 와해를 가져왔다. 동시에 이들 체제수호자들의 이념적 기반이었던 中體西用의 이데올로기적 근본조차 전환 하였다. 즉 그들이 지키고자했던 體로서의 중국적 이념은 用으로서의 서양의 모든 생산양식과 정치체제 및 이데올로기로 인하여 철저하게 와해되었으며 이로 인한 사회문화적 영역에서의 전환도 어쩔 수 없이 수용하게 되는 결과를 가져왔다. 경제구조의 변동은 필연적으로 자본주의 특색을 지닌 상태로 전환되었으며 이에 따른 사회문화영역의 불균형--도시와 농촌의 지역적 불균형과 서양의 접촉이 많은 지역의 거대한 변화와 그렇지 못한 지역의 불변성--이 유지되는 상황으로 중국의 근대사는 진행되었다. 특히 초기 진행된 자본주의 생산양식의 군수산업분야에서 근대적 공업화는 기타 다른 경제영역으로 확장되었으며 그 영향으로 중국의 근대도시화와 사회문화구조에도 심각한 변동을 촉진하였다. 그럼에도 불구하고 양무운동으로 시작된 경제체제의 변화가 근대 중국의 사회문화구조의 분화를 통하여 나타낸 과정은 총체적 역사발전의 순응이었다는 점이다. 이후 역사에서 비록 완전한 발전을 이룩하지는 못하였지만 중국의 근대 자본주의라는 방향으로 진전되는 과정에서 반식민지화로의 진행을 지연시켰으며 민족자본주의의 발전을 양성한 진보적 노력이었다고 평가한다. The aim of the Restoration, T'ung-chich period Self-strengthening was the revival of Confucion values and institutions, but so modified that they might endure. There was within the accepted tradition such a wealth of diverse ideas about how to reach traditional goals that changes in method of government were possible, on the basis of precedent, within the bounds of orthodoxy. The doctrine of change dated from the formative period of Chinese civilization and was at hand to sanction reform throughout the course of Chinese history. During the Restoration the doctrine, in its classic formulation from the Book of Changes, was cited repeatedly in memorials advocating reform : "When a series of changes has run all its course, another change ensues. When it obtains free course, it will continue long." The hope of Restoration was centered on the traditional concept of change; for the ideas and institutions that had two thousand years proved conductive to stability, together with a doctrine of change that had lent flexibility, gave "some ground for trusting that the regeneration of China will be accomplished, like the operation of leaven in meal, without shivering the vessel."

근대(近代) 중국(中國) 상해(上海) 방회(幇會)의 연원(淵源)과 성쇠(盛衰)
이철원 ( Chul Won Lee ) 한국외국어대학교 국제지역연구센터 중국연구소 2010 中國硏究 Vol.49 No.-
Economic enterprise in the Modern Shanghai, like a political career or social life generally, was based on the family unit and depended on the cultivation of personal relationships. Thus trade depended on the family firm, in which kinship created the essential bonds of loyalty. Individuals in a family firm bore an unlimited liability but by the same token could expect family backing in a crisis. In the absence of impersonal legal safeguards and institutions of insurance and commercial law, the principal assets of a merchant were his good name and guarantors, but equally important was his personal relationship with official authorities from whom his firm might have to obtain a formal or informal sanction to do business. The chief defence of commercial class against official manipulation and exploitation was merchant group solidarity. From very early times shops or one kind were situated together on a city street. Merchants in the same line flocked together by order, and by the late Tang or Song in their interaction with officialdom, they developed guilds. In modern Shanghai merchant society growth of their personal relations followed same general practices created the patronage networks. In particular, merchants at a distance from home developed strong ties with other traders from native landers. This became the basis for the Landsmannschaften or regional associations according to native place, likethe Ningpo Guild in Shanghai. The result was a tremendous proliferation of Landsmannschaften, organized sometimes purely by native place and sometimes by line of trade. But until the nineteenth century these voluntary associations had seldom reached the point of consolidating merchant interests and power. Instead the guilds in their various lines of trade and representing various trading places remained fragmented each in their own bailiwick.

The purpose of this study was to explore the effects of leisure sports experience on a cultural adjustment process. In order to explain this, this study analyzed perceived leisure benefit and acculturation for the first generation of Korean immigrants in United States. Even though the research theme is significant, it was not accomplished in the past. In this respect, this study collected and analyzed data of in-depth interview for 8 research informants(4 men and 4 women) living in the United States from 10 to 34 years. Two results were revealed. Firstly, leisure benefit for informants were indicated as four categorizations: 1)maintaining health; 2) enhancing family bonding; 3) social bonding; and 4) psychological well-being. Secondly, leisure sports experience played a great role in acculturation in terms of `integration` and `isolation`. These results makes it possible to understand the importance of lesiure sports in the everyday life for Korean immigrants in the United States.
