W3C는 2006년부터 유비쿼터스 웹 도메인을 신설하고, 웹 애플리케이션을 다양한 기기가 자신에 적합하게 이용할 수 있도록 하는 표준화의 일환으로 기기독립 활동을 시작하였으며, 현재는 유비쿼터스 웹 애플리케이션 활동으로 신설되어 데스크톱 컴퓨터뿐만 아니라 사무자동화기기, 가정용 전자기기, 이동 전화, RFID와 바코드를 포함하는 센서와 이팩터(effector) 등의 다양한 유비쿼터스 기기에서 분산된 웹 애플리케이션의 개발을 단순화하는 표준 개발 작업을 착수하였다. 본 논문에서는 W3C의 DIAL, DISelect, DCCI, CC/PP, SCXML, EMMA를 중심으로 유비쿼터스 웹 표준화 동향을 살펴본다.

아웃바운드(Outbound) 형 콜 센터는 서비스 지향의 인바운드(Inbound) 형 콜 센터와는 달리 전화를 거는 주체가 고객에게 접촉하고자 하는 목적을 뚜렷하게 가진 상태에서 제품 또는 서비스, 정보제공 등을 전화나 기타 커뮤니케이션 채널을 통해 전달하는 업무를 담담한다. 본 논문에서는 아웃바운드 형 콜 센터 시스템을 예측 다이얼링(Predictive Dial Ing) 방식에 기반하여 개선된 콜 전략을 제안한다 개선된 콜 전략은 콜 센터 업무의 중심 역할인 콜링 리스트(Call ing List)를 데이터 추출 모듈을 사용하여 테이블로 구성한 뒤, 시간 활용을 통한 효율적 대응과 다양한 고객들의 정보를 바탕으로 고객과의 접촉확률을 증가시킬 수 있다.

Acording to the trend of highly increasing the public telephone, understanding consumer's design sensibility is based on designing consumer products reflecting user's identity and it comes out as a result of wore competitive products. For this study, consumer's desirous sensibility of the public telephone has been measured in checkable numbers. First of all, 35 sensible words are narrowed down from 168 whole sensible(adjective) words using the SD method. By this result, 7 scale form the SD method is applied to reserch on 10 current distributed products form 30 male and female university students. Element factor analysis is used to group the selected sensible words, duster analysis is used yo dassify them, and finally discriminant analysis is used to predict the relationship between design elements and the sensible words. As a result, words of human sensibility is known to divide into 3 factors; esthetics, functionality and safety, and the correlation of design factor is closely related with the the telephone's body, handset, dial board, dial button, ontrol button, color and material. To sum up, better public telephone design comes out from scientific and systematic consumer's desire analysis not designer's design technique.

"Hon-Chon-Jeon-Do" is a woodcut star map with the size of $79.4cm{\times}127.5cm$, and was widely disseminated as it was made into a set with Kim, Jung Ho's "Yeoji-Jeon-Do". This study confirmed that Yixiang kaocheng xubian ("의상고성속편") star catalogue was used as a source to produce the star map, and the stereographic projection was applied with the projection center being the mid-point (Q) between the celestial and ecliptic north poles. The 'mid-circle' around the Q is arisen between the equator and the ecliptic, and on this circle, the hour angle and the ecliptic longitude of a star can be marked using the same scale. This means that the hour of the day and the season of the year can be read on the same dial of the mid-circle, and the application of this character in the practical use was the key point of the star map production. By observing either transits or positions of the 28 xiu (宿), it is easy to find the corresponding season and time by simply reading the dial on the mid-circle. This is just the function of a portable almanac and thus by disseminating it widely, the convenience of the people would have been promoted. For this reason, it can be stated that "Hon-Chon-Jeon-Do" was a practical astronomical tool which was produced by the western astronomical projection method and was used to find time and season. Choi, Han Ki and Kim, Jung Ho are strong candidates for the makers of this star map. The time of production is estimated to be 1848 ~ 1857, and "Hon-Chon-Jeon-Do" could be regarded as a good contributor to popularization of astronomy in the late Joseon Dynasty.

In this study paper, we examine pre-trained language models used in Multi-Goal Conversational Recommender Systems (MG-CRS), comparing and analyzing their performances of various pre-trained language models. Specifically, we investigates the impact of the sizes of language models on the performance of MG-CRS. The study targets three types of language models - of BERT, GPT2, and BART, and measures and compares their accuracy in two tasks of 'type prediction' and 'topic prediction' on the MG-CRS dataset, DuRecDial 2.0. Experimental results show that all models demonstrated excellent performance in the type prediction task, but there were notable provide significant performance differences in performance depending on among the models or based on their sizes in the topic prediction task. Based on these findings, the study provides directions for improving the performance of MG-CRS.

서비스의 다양화와 방송과 통신의 통합화로 인해 단방향 CATV에서 양방향 CATV의 뉴미디어 시대로 접어들고 있다. 본 고에서는 광 CATV 시스템인 SWAN(Sociocultural Wellbeing Advanced Network)에 VOD 서비스를 제공하기 위하여 미국 VDT(Video Dial Tone)의 수요예측을 통한 가입자망의 구성 종류, 이들 시스템의 초기 설치 비용을 참고로 하여 모델 도입에 경제성을 제고하였다. VOD 서비스를 도입함으로써 중심국과 분배센터간 전송 채널의 용량이 증가하여 전송 효율이 떨어져 서비스 블로킹 현상을 초래하게 된다. 이러한 전송효율의 저하를 방지하기 위한 방안을 제시한 VOD서비스용 광 CATV 시스템의 모델을 정립하였다.

The purpose of this study is to estimate ultimate uplift capacity of permanent anchor which was cast into weathered rock. The ultimate uplift capacity was estimated from the load-displacement curve of four different anchors which have different bond length. The creep test was performed for 15minutes under the maximum load of each step in order to understand the load-transfer property of permanent anchor and to decide which anchor to choose. The destruction range of soil due to the changes in load was estimated by installing dial gauge on the ground which was cast into the weathered rock. Ultimately, the study on the behavior of the anchor case into the weathered rock was performed by comparing and analyzing the estimated result of the UUC obtained by the full scale pull out test in the field with the exsting theoretical and practical results of soil and rock anchor.

When we use various multimedia programs such as 3D-game, visual conference, dial-pad phone by internet service, we make use of headset generally. As internet system is magnified more and more, a demand of headset will be increasing continuously. Because microphone was fixed by headset, it has many inconveniences for using headset. For these reasons, new concept headset is needed nowadays. Main idea of development of headset is very the automatic operation system of microphone. There are many process variables in appling new technology to the conventional headset. They can be solved by using axiomatic approach method which is very useful design method for designing new products. Its main character is scientific and analytical. The goal of this research is to design and manufacture a new headset model with axiomatic design method. In this paper, a new concept headset was presented by mapping the relation between functional requirements and design parameters.

As many crude drugs are used in the oriental medical field problems on the side effects of these drugs come to the front. To conduct delayed-type hypersensitivity we selected 29 kinds of drugs used frequently for therapeutic agents in oriental medical hospitals (Table I). The cell-mediated immune response was evaluated by measuring the foot pad swelling reaction and humoral immune response by measuring the antibody formation to these crude drugs. Mice were given these drugs intraperioneally for sensitization and challenged with same drug as used for sensitization respectively by intral dermal injection on the left and righ hind foot pad 4 days after senstization and then the foot pads were measured with the dial micrometer. The results were as follow; 1) Gentianae Scabrae Radix, Arecae Semen, Corydalis Tuber, and Paeoniae Radix were significant as delayed-type hypersensitivity inducers. 2) None of the crude drugs tested had effect on the induction of humoral immune response.
