Korean private colleges under the period of Japanese control was the kernel for the educational resistance, one of the save-the-nation movements because of inculcating in Koreans the spirit of independence and self-respect under that period. Posung College Library building, erected in Commemoration of the 30th Anniversary of the Foundation, especially, was the result of Koreans systematizing ability and iron will of independence for the future generations. In this paper, an attempt to study the Korean private college libraries under the period of Japanese control is provided. The main institutions in this study are Posung College library, Chosen Christian College library (Yunhee College Library), and Ewha College Library. This study will focus to review the followings: 1. The historical background of above mentioned libraries. 2. The educational resistance under that period. 3. The comparative and analytical study of these private college libraries and Keijo Imperial University library. 4. The facilities and the basic collection development plan on the basis of presentation. 5. library services including readers services. 6. The impact of these libraries on the present private university libraries. 7. The organization and staffing pattern, and budget of these private college libraries. The followings are the outlines conclusions: 1. Korean private college libraries had been established in order to perform the educational resistance. They are one of the supporting agencies for the research activities, among the most important means of social education, and provide, no doubt, the full nutriment for hungry soul under that period. 2. These libraries have not outstripped Keijo Imperial University in collection of books as well as man power, but their collection of books coincided, in general, with their curricula, and had feature to perform the save-the-nation-movement by education. 3. The library services were appeared in the forms such as the Circulation Library, Lectures on the Use of Books and Libraries, Library Week, and Training Course for the Librarians, etc. It is thought that these activities contributed to the social and cultural development of Korea indirectly. 4. The library administration of the private colleges depended upon the director of library because of the frequent changes of staffs and the simple functional system without its middle class. 5. The Japanese Government-General in Korea gave no financial assistance to the private colleges though they were in financial difficulties more than Keijo Imperial University. 6. The ambitious ideal for foundation of universities in reality as well as in name was not achieved during that period because of the monstrous obstacle so-called the Japanese Government-General in Korea, but its ideal had a desirable effect upon these college libraries development, in particular, before and after 1935.

Over for the past 10 years, the increase in geometric progression for the internet traffic, has allowed the IP protocol framework to be the most important network technology. In addition, the internet service is being developed as a service mode differentiated, aiming to support the new-mode real-time multimedia services such as internet phone, video conference, cyber reality, and internet game, focusing on offering a latest service. These days, aiming to solve the need for broad bandwidth along with guaranteeing QoS, the WDM technology of offering multiple gigabit wavelengths is emerging as the core technology of next-generation optical internet backbone network. In the next-generation optical internet backbone network based on WDM, the QoS framework is one of fore subjects aiming to offer a service of guaranteeing QoS This study analyzes the requirements of performance related to QoS framework in IP Subnet and in WDM optical backbone network, and suggests optical QoS service framework differentiated. in order to guarantee end-to-end QoS through the next-generation optical internet backbone network, using GMPLS control protocol. 지난 10년간 인터넷 트래픽의 기하급수적인 증가는 IP 프로토콜 프레임워크를 가장 중요한 네트워크 기술로 만들었다. 더욱이, 인터넷 서비스는 최선형 서비스 제공 위주에서 인터넷 폰, 비디오 컨퍼런스, 가상 현실, 인터넷 게임과 같은 새로운 형태의 실시간 멀티미디어 서비스들을 QoS보장과 함께 지원하기 위해서 차등화된 서비스 형태로 발전하고 있다. 최근, QoS 보장과 함께 광 대역폭의 요구 해결을 위해 다중 기가비트 파장을 제공하는 WDM 기술이 차세대 광 인터넷 백본망의 중심 기술로 부상하고 있다. WDM 기반의 차세대 광 인터넷 백본망에서 QoS 프레임워크는 QoS 보장형 서비스를 제공하기 위한 핵심 과제 중의 하나이다. 본 논문에서는 IP 서브망과 WDM 광 백본망에서 QoS 프레임워크와 관련된 성능 요구사항을 분석하고, GMPLS 제어 프로토콜을 이용하여 차세대 광 인터넷 백본망을 통해 종단간 QoS를 보장하기 위한 차등화된 광 QoS 서비스 프레임워크를 제안한다.

김용성,조원경,Kim, Yong-Sung,Cho, Won-Kyung 대한전자공학회 1996 전자공학회논문지-B Vol.b33 No.1

실시간 컴퓨터 그래픽 처리를 위하여는 고속 연산(승산 및 가산)회로가 필요하다. 잉여수 체계(RNS:Residue Number System)는 병렬성과 고속성을 갖는 정수연산체계이고, 또한 순환군(cyclic group)은 가산과 승산이 동형인 잉여수 연산을 수행하므로 고속의 승산기와 가산기의 설계가 가능하다. 그러므로, 본 논문에서는 DRNS(Double Residue Number System)를 제안하고, 순환부호(circula- tive code)를 이용한 고속의 잉여수 승산기를 설계하여, 이를 그래픽 프로세서의 연산기로 사용하고자 한다. 설계된 승산기는 TTL소자 74s09, 74s32를 사용한 경우 87MHz속도의 연산이 가능하다. To process computer graphics in real time, the high-speed operations(multiplier and adder) are needed to increase the speed of graphic process. RNS(Residue Number System) is integer number system that has the parallel and high-speed operation. Also, it is able to design both high-speed multiplier and adder, since a cyclic group has an isomorphic relation between multiplication and addition in RNS. So in this paper, DRNS(Double Residue Number System) is proposed, it is used for the multiplier and the adder, which are designed using a circulative code for the high-speed graphic processor in RNS. The designed multiplier would operate with the speed of 87Mzz two TTL using 74s09 and 74s32.

김용성,Tatsuya Unno,Byung-Yong Kim,Mi-Sung Park 대한남성과학회 2020 The World Journal of Men's Health Vol.38 No.1

Humans carry numerous symbiotic microorganisms in their body, most of which are present in the gut. Although recent technological advances have produced extensive research data on gut microbiota, there are various confounding factors (e.g., diet, race, medications) to consider. Sex is one of the important variables affecting the gut microbiota, but the association has not yet been sufficiently investigated. Although the results are inconsistent, several animal and human studies have shown sex differences in gut microbiota. Herein, we review these studies to discuss the sex-dependent differences as well as the possible mechanisms involved.

This study attempts to verify the hypothesis that the interdisciplinary communication patterns may be different according to each disciplines. To put it concretely, it is intended to analyze and compare the subject distribution, the format, the age, the origin and the language of the documents of other disciplines cited in the journal articles according to each disciplines. To test the hypothesis philosophy, sociology and physics as the sample for the three disciplines, that is, humanities, social sciences, and natural sciences are sellected, and the documents cited in the journal articles published in 1966, 1971. 1976, 1981 and 1986 by the Korean Philosophical Association, the Korean Sociological Association and the Korean Physical Society are collected. And then the subject distribution, the format, the age, the origin, the language, and their use rate of the documents of other disciplines cited in the journal articles are investigated, analyzed and compared according to each disciplines. Some findings and conclusions made in the study are as follows. 1. The subject distribution of documents of other disciplines cited and its distribution ratio are different according to each disciplines, that is, humanities high, natural sciences low and social sciences medium. 2. The format and the use rate of documents of other disciplines cited are different according to each disciplines. In the three disciplines book and journal are more used than any format of documents in interdisciplinary communication while in case of the humanities and social sciences book is more used than journal, and in case of the natural sciences journal is more used than book in that communication. 3. The age and the use rate of the cited documents of other disciplines are different according to each disciplines. In case of the social sciences and natural sciences the documents of its last 20 years of publication are cited concentrately, and in case of the humanities the literature age is unconcerned. 4. The origin and the language of the cited documents of other disciplines, and its use rate are different according to each disciplines. In the humanities and natural sciences the documents published in foreign country are cited concentrately, and in the social sciences the home publication documents are more cited than the foreign. The documents of other disciplines in English language are most cited among the documents in any foreign languages in interdisciplinary communication. Putting the three disciplines in order of the use rate of the documents in English language, the natural sciences is high, the humanities medium, and the social sciences low. In the social sciences the use rate of the documents of other disciplines in Korean language is high while in the humanities and natural sciences slight.

Recently, research on cost reduction and efficiency improvement of crystalline silicon(c-Si) photovoltaic(PV) module has been conducted. In order to reduce costs, the thickness of solar cell wafers is becoming thinner. If the thickness of the wafer is reduced, cracking of wafer may occur in high temperature processes during the c-Si PV module manufacturing process. To solve this problem, a low temperature process has been proposed. Conductive paste(CP) is used for low temperature processing; it contains Sn57.6Bi0.4Ag component and can be electrically combined with solar cells and ribbons at a melting point of $150^{\circ}C$. Use of CP in the PV module manufacturing process can minimize cracks of solar cells. When CP is applied to solar cells, the output varies with the amount of CP, and so the optimum amount of CP must be found. In this paper, in order to find the optimal CP application amount, we manufactured several c-Si PV modules with different CP amounts. The amount control of CP is fixed at air pressure (500 kPa) and nozzle diameter 22G(outer diameter 0.72Ø, inner 0.42Ø) of dispenser; only speed is controlled. The c-Si PV module output is measured to analyze the difference according to the amount of CP and analyzed by optical microscope and Alpha-step. As the result, the optimum amount of CP is 0.452 ~ 0.544 g on solar cells.

김용성,Kim, Yong-Sung 한국정보기술전략혁신학회 2004 情報學硏究 Vol.7 No.2

잉여수계를 사용한 연산기는 디지털 신호처리, 컴퓨터 그래픽 등에 있어서 여러가지 장점을 갖으므로 전용 프로세서 설계에 사용되고 있다. 그러나 크기 비교와 일반적인 제산에 있어서 단점을 갖는다. 본 논문에서 제안된 연산기는 곱의 역을 사용한 제산의 결과가 나머지를 갖는다면 현재 제수에 의해 산출된 몫의 최대 값보다 큰 값이 발생되는 조건을 반복연산의 종결조건으로 사용하였으며, 몫의 비교를 대응된 제수 값으로 대신하였다. 그러므로, 설계된 연산기는 작은 크기의 제한된 제수를 사용하는 제한점은 갖지만, 컴퓨터 그래픽의 스케일링 등에 적용하는 경우 연산기의 크기 및 속도가 우수한 제산 연산기로 사용할 수 있다.

Systolic Array Processor is used for designing the special purpose processor in Digital Signal Processing, Computer Graphics, Neural Network Applications etc., since it has the characteristic of parallelism, pipeline processing and architecture of regularity. But, in case of using general design method, it has intial waiting period as large as No. of PE-1. And if the connected system needs parallel and simultaneous outputs, processor has some problems of the performance, since it generates only one output at each clock in output state. So in this paper, one dimensional Systolic Array Processor that is designed according to the dependance of data and operations using the partitioned sub-matrix is proposed for the purpose of improving the performance. 1-D Systolic Array using 4 partitioned sub-matrix has efficient method in case of considering those two problems.
