한국사회가 점차 다문화사회로 변모되어 가는 과정에서 이주민 모국어가 포함된 다문화자료의 입수와 관련하여 개별도서관과 사서들은 많은 어려움을 겪고 있다. 이러한 어려움을 완화하기 위한 방안을 모색하고자 본 연구는 북미와 유럽, 호주 등 서구의 도서관계에서는 어떠한 해결책들을 모색해 왔는지를 살펴보았다. 이를 위해 23개의 국가도서관, 주립도서관, 공공도서관, 도서관협력체의 사례를 조사하였는데, 이들은 크게 공동구입 방식과 일괄대출 방식 등 협력기반의 다문화자료 입수방식을 채택하고 있었으며, 지역적으로는 국가적 범위, 주 범위, 도시 또는 도시 내 자치구 범위, 개별 도서관 범위 등으로 구분되었다. 이어서 조사대상 협력체들의 특성을 분석한 다음, 서구의 협력기반 다문화자료 입수방식을 국내 도서관 환경에 적용가능한 방안들에 대해 제언하였다.

This study aims to survey the perceptions held by students and field workers regarding the clothing-related qualification certificates, which can serve as the base for becoming clothing professionals, to compare and analyze the actual state of qualification certificates on the basic research level, and thus to search for the directions suitable for the clothing-related qualification certificates. The questionnaire method was selected for the study. The responses of 406 copies from students and 81 copies from field workers were used, and frequency analysis and t-test were done with the assistance of spss 10.0 statistics program, The findings are as follows. First, as to the qualification certificates perceived by the students, the certificates of colorist engineer and colorist industrial engineer were known most. 237 students, or 58.4% of the student respondents, had obtained the information about the qualification certificates mainly through the internet and mass media, and 77.3% of the students had a plan to get the qualification certificates. Second, as to the qualification certificates perceived by the field workers, the respondents indicated that school grades(43.2%) would be given the highest additional points at the time of employment, while the clothing-related qualification certificates gathered low responses of 11.1%. The field workers perceived that the qualification certificate of Western suit engineer(pattern) was needed for the job, while 45.4% of them perceived that no qualification certificate was required for the job. Third, both the students and the field workers showed low acquisition levels of the qualification certificates, and in view of their perceptions that the qualification certificates of languages or computer skills were more useful, the improvement is needed in order for the national certificates for the clothing-related skill qualification to develop in the more job-related directions.

토지 획득 문제(land acquisition problems)란 일련의 목적에 맞게 서로 인접하고 있는 최적의 토지 필지들을 찾는 것이다. 이 문제는 도시 및 지역 계획과 각종 구획 문제 등에서 사회적 활용도가 높은 분야로서, 공간적 요소인 인접성(contiguity)와 밀집도(compactness)는 중요한 제약요소로 다루어지고 있다. 그렇지만, 공간적 밀집도(spatial compactness)는 완벽한 측정방법이 존재하지 않고, 획득된 필지들의 둘레를 제거나, 모양을 측정하는 등의 여러 가지 방법으로 측정되고 있다. 그리하여 이 논문에서는 공간적 밀집도를 측정하는 새로운 방법을 제시하고자 한다. 인접한 토지 필지간의 내부적인 구조적 특징을 바탕으로 proximity degree라고 불리는 공간적 밀집도를 측정하는 최적화 연구모델(optimization model)을 발전시켰다. 일련의 실험을 통해 proximity degree에 따라 다양한 공간적 밀집도를 가진 모습을 확인할 수 있다.

In general, most incomplete communication link setup between satellite and ground station right after separation from launcher come from less accurate orbital vector ground station uses to track the satellite because only predicted orbital state vector is available during first few orbits. This paper describes the developed procedure for successful initial acquisition for KOMPSAT-2 using scanning functions ofK13 antenna system with predicted orbital information. Azimuth scan, raster scan, spiral scan functions were tested with KOMPSA Tl under intentionally degraded orbital information for antenna operation. Through tests, spiral scan function was decided to be best search scan among 3 scans. Developed procedure can assure the successful acquisition only if azimuth offset and time offset value are within +/-2deg and +/-30sec, respectively.

This paper is focused on implementing a real-time data acquisition system that checks power facility status by applying network based technology to Urban Transit substation power facilities and the results of its on-field tests. This system is composed of a sensor part, a measurement part, a transceiver part, a host computer, and a power source part. The system is designed to collect, save, analyze, and display the online state power facility AI (Analog Input). This system measures voltage and current from positive feeders and negative feeders where it is possible to check abnormalities of the substation‘s main power facilities. By monitoring abnormal data of the Urban Transit power facilities real-time and analyzing stored data, establishing procedures of optimized maintenance is possible.

Facilities of electric railway should be maintained only at night and it is necessary to maintain by human power because facilities are installed at a high place. This paper presents the development and application of a real-time data acquisition system for the characteristics measurement of overhead contact wires in electric railway. The system is designed to perform in the telemetry environments that developed to store data by wireless in a live wire state of 25 kV power source. The field test results show that the proposed technique and the developed system can be practically applied to measure characteristics of temperature, displacement, and strain on overhead contact lines.

AutoCor is a method for the automatic acquisition and classification of corpora of documents in closely-related languages. It is an extension and enhancement of CorpusBuilder, a system that automatically builds specific minority language corpora from a closed corpus, since some Tagalog documents retrieved by CorpusBuilder are actually documents in other closely-related Philippine languages. AutoCor used the query generation method odds ratio, and introduced the concept of common word pruning to differentiate between documents of closely-related Philippine languages and Tagalog. The performance of the system using with and without pruning are compared, and common word pruning was found to improve the precision of the system.

The objective of this research is to develop a knowledge acquisition and refinement method for a multi-objective and multi-decision FMS scheduling problem. A competitive neural network and an inductive learning algorithm are integrated to extract and refine necessary scheduling knowledge from simulation outputs. The obtained scheduling knowledge can assist the FMS operator in real-time to decide multiple decisions simultaneously, while maximally meeting multiple objective desired by the FMS operator. The acquired scheduling knowledge for an FMS scheduling problem is tested by comparing the desired and the simulated values of the multiple objectives. The result show that the knowledge acquisition and refinement method is effective for the multi-objective and multi-decision FMS scheduling problems.

This paper describes the application method of systems engineering for systems of systems and addressed the evolution in approach as organizations have evolved from standalone platform providers to architect of SoS. There is an increasing need to perform Systems of Systems Engineering(SoSE) in a global environment This has stimulated the development of new, innovative SoSE approaches that surpass current military and industry state-of-the-art systems engineering processes. The simple scaling of the former process was ineffective in dealing with global distributed large-scale integration efforts of network-centric systems of systems. A new SoSE process has been developed which is a significant breakthrough in the development of large complex systems and net-centric systems of systems. The SoSE process provides a complete, detailed and systematic development approach for military and civil SoS. In this point of view, this paper analyzes functionally the architecture framework, process and integrated verification & validation of SoSE. From results of this analysis, perspectives on the application of SoSE suitable for Korea aquisition environment are presented.
