  • The annals of the Chosun dynasty (朝鮮王朝實錄). on CD-ROM was studied to understand e ceremony and dietary culture of the Chosun dynasty. The Chunshin (薦新) ceremony. the service of offering the first food product of the year to ancestors, was begun in the Song dynasty in China and initiated in the Koryo dynasty in Korea. Chunshin ceremony as the national auspicious ceremony was settled through the 311 the Chosun dynasty. The offerings were graded and the Saongwon (司饔院) was in charge of the transportation of them. A king attended the ceremony in person at Jongmyo (宗廟) once in a while. but the Bongsangsi officials usually took charge of ceremony. Even though the harvest of crops had failed due to the drought. the quantity of the offering was not curtailed. Seven kinds of the new products It ere offered in the Koryo dynasty, twenty-seven kinds of them during the reign of king Sejong, and thirty-one kinds of the them during the reign of King Sungjong according to the Gukjooreeui (國朝五禮儀) (1474). The offerings were served on the utensils called Du (두(豆)), Byun (遼), and Jak (爵). Most of the of the offerings were dedicated by public officials and civilians. The meat products in particular were caught by the king on hunting trips, and offered by the king in Person.

  • 개인용 컴퓨터가 많이 보급되고, CD-ROM과 같은 대용량의 기록장치가, 널리 퍼지면서, 전자화된 사전이 널리 사용되게 되었다. 그러나 이러한 전자사전들은 대개 매우 단순화된 탐색기능만을 제공하므로, 전자화의 잇점을 크게 살리지 못하고 있다. 따라서, 컴퓨터의 힘을 빌린, 보통의 종이로된 사전보다 훨씬 유용한 전자사전을 생각해 볼 수 있을 것이다. 이러한 노력이 과거 80년대 말에 하이퍼텍스트로 시작되어 이제는 매우 상업적인 곳에까지 사용되어지고있다. 국내에서도 전자사전의 개발은 다양하게 진행되어오고 있으나, 대부분 컴퓨터를 위한 사전, 다시 말하면, 빠른 접근시간, 적은 메모리사용만을 고려한 사전에 그치고 있다. 본 논문에서는 이러한 필요성에 부합하여, 백과사전자료를 가지고 사람을 위한 전자백과사전을 개발하는 방법을 소개한다. 특히, 이러한 개발과정을 자동화 할 수 있음을 보이고, 백과사전을 하이퍼텍스트로 자동변환하는 방법을 자세히 기술한다. 이 방법은 원시 자료를 하이퍼텍스트로 변환하기 좋은 정형화된 중간자료로 바꾸고, 이 중간자료와 기초적인 명사추출 알고리즘을 이용하여, 각 노드들 사이에 링크를 만드는 것이다. 또한, 이 방법을 이용하여 개발한 HE(Hypertext Encyclopedia) 시스템을 소개한다.

  • Using statistic and bibliometric methods to characterize scientific cooperation between China (excluding Hong Kong, Macao, and Taiwan) and South Korea through their bilateral co-authored papers covered by the Science Citation Index CD-ROM, 1991-2010, in our paper we exploit the feature of their cooperation in four levels: time sequence, academic community, key fields, and institution distribution. From the time sequence we know that collaboration between China and Korea starts in 1991, reaching the first peak during 2004-2007. As for the academic community, the number of Chinese corresponding authors (2414) is slightly lower than that of Korea (2700). Regarding the 27 high yield authors, there are only 4 coming from China. Korea has a higher active level than Chinese authors. China and Korea tend to cooperate with each other on strong disciplines such as physics, chemistry, material science, engineering, mathematics, pharmaceutical, computer science and biology. Furthermore, they also attach great importance to basic research and high-tech cooperation. Besides, Chinese Academy of Sciences ranks at the top 1 among the distribution of institutions. As a majority of the collaborative institutions are universities, the participation of non-university institutions is relatively low. There are 7 Korean universities among the top ten institutions, while Yanbian University and Tsinghua University in China rank respectively as third and fourth. Seoul National University, accompanied by Korea University and Yonsei University as the three top Korean universities, is also among the top among the cooperating institutions.

  • The wetness, a function of precipitation and temperature etc, and the warmth, a function of temperature, are the dominant factor for global vegetation distribution. This paper employs the normalized difference vegetation index (NDVI), warmth index (WAI), and wetness index (WEI), and focuses on an essential climate-vegetation relationship at global scale. The NDVI was acquired from ‘Twenty-year global 4-minute AVHRR NDVI dataset.’ The WEI is defined as the fraction of the precipitation to the potential evaporation. The WAI was calculated by accumulating the monthly mean temperature of the portion exceeded 5$^{\circ}C$ throughout the year. Meteorological data for the WEI and WAI calculation were obtained from the ISLSCP CD-ROM. All analyses were conducted for 1 ${\times}$ 1 degree grid box on the terrestrial area of the Earth, and on annual value basis averaged in 1987 and 1988. The result of analyses demonstrated that there are two regimes in their relations, that is, a regime in which NDVIs vary depending on the WEI, and a regime in which NDVIs vary depending on the WAI. These two regimes appeared to correspond to the wetness dominant and warmth dominant vegetation, respectively. The geographical distributions of two regimes were mapped. Most of the world vegetation is categorized into wetness dominant, while warmth dominant vegetation is seen in the high-latitude area mainly to the north of 60$^{\circ}$N in the Northern Hemisphere and high-altitude areas.

  • Dynamic behaviors are analyzed for an automatic ball balancer (ABB) with triple races, which is a device to reduce the unbalanced mass of optical disk drives (ODD) such as CD-ROM or DVD drives. The nonlinear equations of motion are derived by using Lagrange's equations with the polar coordinate system. It is shown that the polar coordinate system provides the complete stability analysis while the rectangular coordinate system used in other previous studies has limitations on the stability analysis. For the stability analysis, the equilibrium positions and the linearized perturbation equations are obtained by the perturbation method. Based on the linearized equations, the stability of the system is analyzed around the equilibrium positions; furthermore, to confirm the stability, the time responses for the nonlinear equations of motion are computed by using a time integration method and experimental analyses are performed. Theoretical and experimental results show a superiority of the ABB with triple races.

  • A noncontact optical system that can measure displacement or vibration of an object is designed by employing the oblique ray method. By using a single convex lens which serves as both the input and output lenses, we made the optical system very compact and reliable. In addition, the bandwidth of the vibration measurement is more than 100 KHz by using the position-sensitive detector as the beam position sensor. The resolution and capture range of the system are $\pm$1 ${\mu}{\textrm}{m}$ and 1100 ${\mu}{\textrm}{m}$, respectively. As a sample test, the vibrations of a speaker and a rotating compact disc surface were measured.

  • This paper discussed the factors that necessitated information networking, types of networks, benefits of information networking, library information networking and the University of Port 0Harcourt library network initiatives. Information networking is a process of communication, exchange of ideas, resource sharing and collaboration between individuals, organizations, institutions and libraries and it is facilitated by ICTs and the internet for improved accessibility. It has been brought about by information explosion, rapid advancement in information communication technologies, inadequate funding and increased demand for quality information. Networks can be classified into local, national, regional, and international networks and are formed to serve different categories of user communities. Benefits of information networking include resource sharing, on-line conferences and participation in programmes at distant centers, collaboration among scholars in different countries. Communication flow through the internet, social media, and electronic mail. Library information networking started with the interlibrary loan which has metamorphosed into library consortia in which groups of libraries partner to coordinate activities, share resources and combine expertise. The University of Port Harcourt Library network initiatives started with an e-granary (a CD ROM) and the establishment of a local area network. The library subscribes to more than 10 electronic databases. Information networking has greatly improved the sharing of resources in acquisition and dissemination of information resources since no single institution can acquire the overwhelming number of information resources in their various formats.
