Multi-lingual query answering system is the system which answers on the queries with several languages. LASSO[l] is the system that aims to answer the multi-lingual query. In this paper, we design and implement a Korean analysis system for LASSO. The Korean analysis system for query answering needs processing techniques of dialogue style. And the system must be practical and general so as to use on various domains. This system uses not dialogue processing techniques with high cost and low utility but heuristic rules with low cost and high utility. It is designed and implemented as a Korean interface of multi-lingual query answering system. The techniques of this system highly contribute to information retrieval and Korean analysis researches.

In this paper, the android platform based on the morning call system using multi-point group communication is proposed. Implemented multi-point group communication was applied by fusing a variety of techniques such as JAVA NIO, JSP, MySQL, DBMS Pool, GCM and JSON. Some experiments are conducted so as to verify the proposed method, and as a result, morning-call application based multi-point group communication is well performed.

For a class of multi-input multi-output nonlinear systems which perform a given task repetitively, an extended type of a direct leaning control (DLC) is proposed using the information on the (vector) relative degree of a multi-input multi-output system. Existing DLC methods are observed to be applied to a limited class of systems with the relative degree one and a new DLC law is suggested which can be applied to systems having higher relative degree. Using the proposed control law, the control input corresponding to the new desired output trajectory is synthesized directly based on the control inputs obtained from the learning process for other output trajectories. To show the validity and the performance of the proposed DLC, simulations are performed for trajectory tracking control of a two-axis SCARA robot.

본 연구에서는 아이솔레이터(Isolator)의 핵심소재로 사용되는 YIG-ferrites를 수열합성법에 의해 초미세 분말로 합성하고, 합성된 분말을 원료로 사용하여 제조 공정된 YIG-ferrites 소결체의 미세구조와 전자기적 특성에 관하여 고찰하였다. 수열합성법(Hydrothermal synthesis method)으로 YIG［ $Y_3$F $e_{5}$ $O_{12}$］분말을 먼저 합성하고 Ca, V, In, Al 등을 첨가시킴으로서 $Y_{2.1}$C $a_{0.9}$ $Y_{4.4}$ $V_{0.5}$I $n_{0.05}$ $O_{12}$의 조성을 지닌 시편을 제조하였다. 초기열처리는 30$0^{\circ}C$에서 90$0^{\circ}C$의 온도 범위에서 15$0^{\circ}C$간격으로 진행하였다.. 그 결과 75$0^{\circ}C$로 초기열처리 하였을 경우 단일 YIG peak가 나타남을 알 수 있었다. 수열합성법으로 제조된 YIG 소결시편의 전자기적 특성은 일반 시약급원료를 사용하여 제조된 소결시편과 비교하여 마이크로파 특성을 평가하였다. 그밖에 YIG-ferrites의 결정성, 미세구조, 자기적 특성, 마이크로파 특성을 XRD, SEM, VSM, Network Analyzer를 이용하여 고찰하였다.여 고찰하였다.다.다.다.다.

This study presents a new retrieval system developed to consider various preferential requirements for buyers in the real estate market. The paper analyses essential factors affecting the price of real estate and then a set of factors are classified by region-related factor and individual-related factor. After endowing the buyer's selected factors with weights in the retrieval system, the optimal solutions have been drawn by comparing with the others through an entropy measure of Multi-attribute Decision Making. This retrieval system is applied to the Busan real estate market to estimate the solutions of retrieval. Evaluation results indicate that the retrieval system can provide useful information to analyse the price determination factors of real estate, as well as to save the searching cost of the buyers.

The explosive growth of Internet traffic cause by smart equipment such as smart phone has led to a dramatic increase in demand for data transmission capacity and network control architecture, which requires high transmission rates beyond the conventional transmission capability. Next generation networks are expected to be controlled by Generalized Multi-Protocol Label Switching(GMPLS) protocol suite and operating at multiple switching layers. In order to ensure the most efficient utilization of multilayer network resources, effective global provisioning that providing the network with the possibility of reacting in advance to traffic changes should be provided. In this paper, we proposes a new path selection scheme in multilayer optical networks based on the vertical PCE architecture and a different approach to efficiently exploit multiple PCE cooperation.

Multiparty conference service based on SIP supported by VoIP network is gradually increased in use and the continuous development and standardization works on SIP are in the process of advancing. But SIP used in currently does not support identity discovery and distribution of each participant for multipath conference. In this paper, a SIP extension method for guaranteeing security from the multiparty conference based on SIP is proposed. We design a new SIP header and method for discovering and distributing a participant's identity in closed multiparty conference when the call initiation is established. And it can ensure that each participant is notified before a new participant joins.

A multi-noded cable element allowing sliding at its nodes without frictions was introduced in this paper, and its elastic stiffness matrix was derived. A two-node truss element was briefly summarized and extended to multi-node, cable-truss elements that keep their tension constant but are connected without frictions through several nodes. The element elastic stiffness matrix of the multi-node,cable-truss elements was consistently derived. The steel wales pre-stressed externally in the IPS system were chosen as numerical examples and analyzed under various loading conditions. The cable tensions calculated using the present element were compared with the results of the flexibility method and those using the two-node truss element, respectively.

A many-to-many k-disjoint path cover (k-DPC) of a graph G is a set of k disjoint paths joining k distinct source-sink pairs in which each vertex of G is covered by a path. In this paper, we investigate many-to-many 2-DPC in a double loop network G(mn;1,m), and show that every nonbipartite G(mn;1,m), $m{\geq}3$, has 2-DPC joining any two source-sink pairs of vertices and that every bipartite G(mn;1,m) has 2-DPC joining any two source-sink pairs of black-white vertices and joining any Pairs of black-black and white-white vertices. G(mn;l,m) is bipartite if and only if n is odd and n is even.

The purpose of this study is to analyze the integration and separation phenomenon of the legislative network by analyzing the Legislative cosponsorship networks in the process of multicultural, family, and gender legislation. First, I analyzed the Legislative cosponsorship networks centered on the proposed bills in the Women and Family Committee. Second, Analyze the network of joint initiatives for multicultural, family, gender related legislation and representative laws in each field. In this process, we analyze who participates in the Legislative cosponsorship networks and who is the leader of the political coalition. Finally, Understand the shared characteristics and differentiated characteristics of policy networks according to policy issues.
