  • The study is to trace the origin of the Hongmunkwan ana discuss its development and roles assigned in each succeeding stages of the history. The Hongmunkwan lived a long life through Koryo and Yi dynasties. It was a multi-functioned institution designed as a royal library, an educational institution, and a political reference center. Prior to the Hongmunkwan, there were some established institution with similar functions to its ones during the Three-Kingdom Era. One of such kind was the Sungmunkwan(崇文館), which was eventually renamed the Hongmunkwan by King Songjong(成宗) of Koryo in 995, and a distinguished scholar-minister was appointed at the position of directorship for management of the now status-raised institution where state documents and books were housed. The Hongmunkwan experienced some reforms during its long life. In 1420, King Sejong(世宗) of Yi Dynasty founded the Jipyonjon(集賢殿) within the royal palace in place of the Hongmunkwan. The Jipyonjon was an innovated Hongmunkwan where many scriptures were stored and distinguished scholars and officials studied on them, sometimes delivering lectures to the king. King Sejo(世祖) abolished the Jipyonjon in his second year(1456) and reestablished the Hongmunkwan designed as a royal library in place of the former in his ninth year. King Songjong(成宗) in his 10th year (1479) of the reign, reformed the Yemunkwan(藝文館), which existed from the beginning of the Yi dynasty, by extending its functions and afterwards absorbed it into the Hongmunkwan together with the functions of the former Jibhyonjon which were included in the Yemunkwan. He founded another Yemunkwan which had the roles of drafings and descriptions of royal decrees. In the 10th year (1504) of Yonsankun(燕山君), the Hongmunkwan was abolished and instead of it the Jindokchong(進讀廳) was founded with less authority and functions. But shortly after that, King Jungjong(中宗) refounded the Hongmunkwan with the same scale, same authority and same functions as the former, one. As the Hongmunkwan also had a function of the royal library it collected and kept numerous books and writings in it. Some books and writings of the Hongmunkwan were composed of those which had been transmitted from the Koryo Dynasty and the others were composed of those which had been collected in the country or purchased by the trade with China in the Yi dynasty. Also newly-compiled important books in the country were reprinted and one of them were send to the Hongmunkwan. In the 8th year (1784) of King Jongjo(正祖), the history of the Hongmunkwan, entitled the Hongmunkwanji(弘文館志), was written and editioned by the royal decree and it was reeditioned the 7th year (1870) of King Kojong(高宗). The Hongmunkwan was absorbed into the Kyujanggak(奎章閣) in 1907.

  • 최근 다양한 멀티미디어 서비스를 지원하기 위한 통신망 관리와 서비스 관리가 통합된 개방형 정보 통신망의 구조가 요구되고 있다. 이러한 구조를 기반으로, TINA-C(Tele-communications Information Networking Architecture-Consortium)에서는 분산 환경에서 분산 어플리케이션 객체들에 대한 복잡한 서비스 및 관리 인터페이스들을 간결하도록 객체그룹의 개념을 정의하고 있다. 이러한 환경 속에서 트레이딩 서비스는 통신 서비스를 제공하는 객체그룹간의 상호작용을 지원하는데 매우 중요하다.따라서, 본 논문에서는 객체그룹간의 상호접속을 지원할 수 있는 트레이딩 기능과 이들 트레이더들간의 연동을 위한 트레이더 연합 모델을 제시하고자 한다. 이를 위해 우리는 트레이더의 중개자로서 Cooperator를 설계하여 기존의 트레이더와 연동시켰다. 이러한 결과로서 우리의 새로운 트레이더 연합 모델에서 Cooperator는 객체그룹간의 상호접속에서 객체들의 접속 권한의 체크 기능과 기존의 트레이더 연합모델의 문제점인 트레이더들간의 단 방향 연결문제를 보완하여 양방향 연결 기능을 갖도록 하였다. 끝으로, 이러한 해결 과정을 보이기 위해 트레이더와 Cooperator들로 이루어진 본 연합모델에서 분산 객체그룹간의 상호접속 절차과정과 사건 추적 다이어그램을 보였다.Abstract Recently, the open networking architecture is required to support various multimedia services as integrated functions of network management and service management. Based on this architecture, TINA-C defines an object group concept for simplifying complex management and service interfaces, when distributed application is executed in distributed environments. Within the support environment the trading service is an important of the interacting object groups which provide a telecommunication service.Hence, we suggest the trader federation model for supporting interconnections between object groups and among existing traders by using the cooperator we designed, as an intermediator among traders. Our cooperator has functions for checking access rights of objects in object groups, and for providing bidirectional linkage among traders. Up to now, the existing trader federation models have a single directional linkage for interactions among traders. Finally, we showed the interface procedure and the event trace diagram of distributed object groups using our model consisted of traders and the cooperators.

  • 본 논문에서는 IEEE 802.15.4의 성능을 정확하게 평가하기 위하여 ns-2에 추가한 두 가지 기능을 소개한다. 첫째는 전체 노드의 수와 은닉 노드의 수가 정해짐에 따라 노드들의 배치를 자동으로 결정하는 은닉 노드 배치 방안과 은닉 노드로 인한 신호 충돌을 구별하는 방안이다. 둘째는 2003 표준만 구현되어 있는 현재의 ns-2 2.33 버전에 2006 표준에 기술된 CCA 지연 처리 방안을 구현하였다. 기능이 확장된 ns-2를 이용하여, 802.15.4 네트워크의 성능에 은닉 노드와 CCA 지연에 대한 처리 방안이 미치는 영향을 정확하게 분석할 수 있게 되었다. 시뮬레이션 결과 은닉 노드가 없을 때에 비하여 은닉 노드가 단 하나 존재할 때 네트워크 처리량이 약 66% 감소하며, 충돌율은 65%에서 90%로 급증한다. CCA 지연 처리 알고리즘의 2003 표준과 2006 표준에 따르면, 충돌 확률은 약 19%까지 차이를 보이고, 처리량은 약 38% 차이를 보이며 2006 버전이 우수한 성능을 보인다.

  • 최대주기를 갖는 수열들의 상호상관함수에 대한 연구는 수십년간 이루어져 왔다. 본 논문에서는 n=2m을 만족하고 최대주기 $2^n-1$을 가지면서 Niho type의 데시메이션 $d=2^{m-2}(2^m+3)$에 대하여 비선형수열$S_a^r(t)=Tr_1^m\{[Tr_m^n(a{\alpha}^t+{\alpha}^{dt})]^r\}$의 상호상관함수 값을 구한다. 특히, $d{\equiv}1(mod\;2^m-1)$을 만족하는 d를 Niho type의 데시메이션 이라고 한다. 그리고 위상이동차 ${\tau}=(2^m+1)k(0{\leq}k{\leq}2^m-2)$인 경우에 대하여 $S_a^r(t)$의 상호상관함수 값의 분포를 분석하고 실험 결과를 제시한다.

  • 최근 들어 뇌과학적인 연구가 활발해짐에 따라 두뇌기능을 공학적으로 응용하려는 연구가 많아지고 있다. 두뇌 기능 중 기억과 감정을 담당하는 부분을 살펴보면 기억을 담당하는 해마체와 감정중추인 편도체가 긴밀히 협조하고 있는 것을 알 수 있다. 실제적으로 지식은 감정에 영향을 미치고 감정은 지식에 영향을 미친다. 인간의 모든 판단과 결정에 있어서 감정요소는 배제할 수 없는 아주 중요한 영향을 미친다. 보다 정교한 지능 시스템을 구축하려면 감정이 결합된 지식베이스를 설계하여야 한다. 따라서 본 논문에서는 해마체와 편도체의 공조 시스템에 착안하여 지식과 감정이 결합된 지식감정 결합 시스템을 설계하고 기억회상과 추론 과정에서 변화하는 감정 상태의 추이를 감지하는 메커니즘을 제안하고자 한다.

  • All over the value chain, a logistics information system must satisfy several requirements about gathering and sharing related information. For example, distributors or forwarders need up-to-date information for scheduling and managing their logistics resources. Meanwhile, consignors or consignees want to know the dynamic information about current states or location of their goods. Such information is dependent upon the quality of data sets collected throughout the logistics processes. Thus, gathering accurate data promptly is the essential factor for the success of a logistics information system. However, there are limits in reducing both time-gap and man-power for datn sourcing, since this process is done manually or by using bar codes and scanning devices. Smart-tag can be the alternative to such n time-consuming and inefficient operation, especially for handling piles of goods. The tag includes a micro-chip containing data which is remotely readable by readers with antenna. Logistics system with Smart tag can provide all the information anywhere and anytime, and it will increase the efficiency of logistics and satisfaction of users. In this paper, we propose a conceptual architecture for smart-tag based logistics system and describe its functions.

  • The libraries that existed during the latter period of the Yi Dynasty may be categorized into four types: the royal library, the school library, the clan community library, and the private library. Of these, the clan community library has yet received very little attention in the study of Korean libraries. In this study the author discusses the purposes, functions, and collections of the clan community library to clarify what that particular type of old libraries in Korea was. The clan community library functioned within individual clan communities to give young people Korean traditional education protecting them from possible influences of. Japanese version of Western scholarship which had threatened the traditional value systems of the society. The author believes that the clan community library was a unique community institution created by Korean people, and the Korean public library movement should trace its origin back to the activities of the libraries. Unfortunately the growing suppression and control of the Japanse colonial regime upon the traditional schools made the purposes and development of the clan community library movement a tragic experience before its flowering. The clan community library was a Korean native public library which came out in response to a historical situation and community need. It may deserve more attention in future study of the national library movement of Korea.

  • For model calibration in rainfall-runoff modeling, streamflow data at a specific outlet is obviously required but is not sufficient to identify parameters of a model since numerous parameter combinations can result in very similar model performance measures (i.e. objective functions) and indistinguishable simulated hydrographs. This phenomenon has been called 'equifinality' due to inherent parameter uncertainty involved in rainfall-runoff modeling. This study aims to investigate catchment responses in time and space to various uncertain parameter sets in distributed rainfall-runoff modeling. Seven plausible (or behavioral) parameter sets, which guarantee identically-good model performances, were sampled using deterministic and stochastic optimization methods entitled SCE and SCEM, respectively. Then, we applied them to a computational tracer method linked with a distributed rainfall-runoff model in order to trace and visualize potential origins of streamflow at a catchment outlet. The results showed that all hydrograph simulations based on the plausible parameter sets were performed equally well while internal catchment responses to them showed totally different aspects; different parameter values led to different distributions with respect to the streamflow origins in space and time despite identical simulated hydrographs. Additional information provided by the computational tracer method may be utilized as a complementary constraint for filtering out non-physical parameter set(s) (or reducing parameter uncertainty) in distributed rainfall-runoff modeling.

  • Woods have been the familiar constructional materials because they were well suited to natural environments of Korea in terms of history regionalism and nationality. Since the modernization of Korea the wooden structure have mostly disappeared because of constructional costs regulations and convenience. But wooden constructions will reappear because of a prediction of wood demand and supply various choices for life circumstances and various investigations. There are many such cases. Among them Japan became an interesting object of investigation. New wooden constructional structures with new materials and modern skills may be observed in Japan. The purpose of this study is to trace architects' consciousness and to analyze constructions with the combination of wooden and other materials in Japan. Thus we explore a possibility to construct a new wooden structure which is suitable in modern Korea. The results were as follows: First the consciousness of Japanese architects' mixed wooden construction corresponds to the close relations between society and environment. Second the space of a structure with mixed wooden constructions in present Japan is chosen as the best way to consider functions and environments according to the form of need space scale and quality. Third the structure wooden constructional structure is a part of roof open space. in this case woods are represented and composed of japanese traditional wooden structure with new technique. Forth a mixed wooden construction has been used through a merit of each material by mixed of different materials as well as beauty of form.
