통신처리시스템(Communication Processing System)은 전화망과 ISDN 가입자들에게 전국 규모의 PC 통신 및 인터넷 액세스를 가능하게 하기 위한 망정합 장치이며, 동시에 관련 서비스 관리 기능과 같은 통신처리 서비스를 제공하는 시스템이다. 그러나 다수의 PC 통신과 인터넷 서비스 제공자들이 등장함으로써 가입자들에게 이러한 복수의 서비스 제공자 시스템으로의 동등 서비스 접속 기능을 제공하기 위해서는 시스템 내부에 고속 Switching Fabric을 통한 스위칭 기능 및 서비스 제공자에 대한 선택 기능이 요구된다. 본 논문에서는 이러한 통신처리시스템의 시스템 구성 개요 및 사용자들에게 서비스 선택 기능을 신축적으로 제공하기 위한 내부 스위치를 사용함으로써 1200 채널 규모의 PC 통신 및 인터넷 액세스 서비스 기능을 제공하는 시스템의 설계 및 구현내용을 중심으로 기술한다. 또한 시스템의 성능 및 용량 설계를 위한 LAN 스위치의 설계 모델, 기능적 요구사항, 그리고 설계 및 구현 내용에 대해 기술한다.

Shinyeojuryeom is a set of bamboo blinds[Juryeom] enclosing the Korean litter for transporting a mortuary tablet of royal family[Shinyeo] in Joseon dynasty. The blinds were made up of twigs laid horizontally which were joined together by vertical threading, then they were lined and backed with silk fabric. A number of historical documents such as Gukjosangryebopyeon(1758), JeongjoGukjangdogameuigwe(1800) and Gukjangdogam- myeongseseo(1905) provide information on material and structure of the litter and blinds. How- ever, detailed dimensions or specific ingredients of some of the materials were not clearly explained. In order to complement these missing or unclear parts, a close examination and scientific analysis of the litter's material was undertaken. The result newly identified materials of the gold tip tassels and pigments used on twigs as well as partly confirmed information on historical records. This new information will help further understanding and future production of a replica.

시스템을 안정적으로 운용하기 위해서는 신뢰성 기반의 로그관리시스템이 필요하다. 모든 이력이 기록되는 로그의 위·변조를 방지하기 위해 로그 정보를 블록체인 기술로 관리하여 어떠한 상황에서도 시스템 이력을 신뢰할 수 있는 서비스를 제안한다. Hyplerledger Fabric을 사용하여 인증 관리 시스템에 의해 허가된 사용자만이 접근할 수 있다. 또한 분산원장에 한 번 기록된 로그 파일은 더 이상 수정하거나 삭제될 수 없다. 이 시스템을 활용하면 로그 파일의 위·변조 여부를 판단하는데 발생하는 시간, 비용, 불확실성을 크게 줄일 수 있을 것으로 기대된다.

EMR 시스템은 환자들의 진료, 처방 및 개인정보들을 중앙집중형으로 관리하는 시스템이다. 기존 EMR 시스템은 수기로 작성하던 진료기록을 컴퓨터를 통해 전자문서 형태로 관리하고 있다. 그러나 EMR 시스템은 외부로부터 해킹이나 데이터 유출에 대한 피해가 우려된다. 본 논문에서는 블록체인 기반의 하이퍼레저 패브릭과 DID를 사용하여 EMR 데이터를 분산 저장하여 환자의 진료기록을 안전하게 관리하는 시스템 기법을 제안한다.

의료기관에서 접근이 용이한 마약류 약물로 오남용하는 사례가 지속적으로 증가하고 있다. 이를 해결하고자 본 논문은 블록체인 프레임워크인 하이퍼레저 패브릭을 기반으로 구축된 약물 오남용 관리 시스템을 제안한다. 하이퍼레저 패브릭의 분산 원장 기능을 사용하면 의약품 거래를 투명하게 기록하고 처방 기록을 안전하게 보존하여 모든 거래 세부 정보를 변조할 수 없게 된다. 또한 약물 사용 기록을 추적하고 남용을 방지하기 위해 과다 복용 사용자를 규제하는 기능을 제안한다. 본 논문이 약물 오용을 크게 완화하고 과다 복용 사용자 보호가 가능할 것이라 기대한다.

Misguided use, manipulation, misappropriation, disruption and mismanagement of Information deeply affects the infosphere as well as the social and moral fabric of a society. Information ethics is an attempt to bring the creation, organization, dissemination, and use of information within the ambit of ethical standards and moral codes. The diverse and inherently pluralistic nature of societies however puts forth an additional demand on us - to come up with an intercultural information ethics. An intercultural ethics which is other-centric, context sensitive and workable without being homogenizing, patronizing and colonizing. An endeavor in that direction has already been made by proponents of intercultural information ethics like: Charles M. Ess, Fay Sudweeks, Rafael Capurro, Pak-Hang Wong, Soraj Hongladarom et al. In our paper, we propose that the kind of ethical pluralism being sought in the domain of information ethics can be attained by having a reappraisal of the current methodological strategies, by casting a critical relook at the Eurocentric ethical model. This paper analyses the current framework of Intercultural Information Ethics. And in an endeavour to move towards an all-encompassing, other-centric, workable, intercultural, harmonious and compassionate model of 'Pluralistic Information Ethics', it proposes the Indian / Asian philosophical method of 'Samvāda' to the current inventory which includes methods like: 'parrhesia/free speech' and 'interpretive phronēsis.

The purpose of the present study was to analyze the acceptance level of forecasted information of casual wear in tate 1990s in Korea and the way of utilizing fashion trends information by casual wear industries. The Present study was implemented by content analysis and descriptive survey using questionnaire and interview. Trends information in fashion journals published by fashion institute and articles in daily newspapers were analyzed in terms of fashion image, color, fabric, and silhouette. The data collected from questionnaire and interview with 113 fashion specialists were analyzed through frequency, percentage. The results indicated that among the forecasted information regarding fashion image, romantic and feminine images showed a high level of acceptance to national brand women's casual wear in the late 1990s, while mannish image showed a low level of acceptance. For men's casual wear in the same time period, androgynous trends appeared most frequently, not only in forecasted information, but also in actual trend. it was forecasted that yellow, white, and gray would be in trend and those colors appeared frequently in actual trend. On the other hand pastel tone appeared much more frequently than forecasted. Natural, thin - transparent (S/S) and stretch fabrics (F/W) were in actual trend as it was forecasted. Fit and Pare (woman), and long and slim (man) silhouettes were in actual trend as if was forecasted, but barrel silhouette appeared only in forecasted information. Most of the information forecasting fashion trends for next season were applied to the product planning of the season, right after the information comes out.

For the commerce of sensual goods such as textile products, feel and touch is very important. Although on-line B2B commerce in textile materials are increasing currently, off-line sample exchange process is also required in order to make a decision. So far it is evident that the means of on-line communication is not sufficient to both customers and suppliers. The aim of this study is to improve the e-catalogues, which is the equivalent of showroom of off-line business, by analyzing information items offered in currently opened B2B sites and to categorize the essential information items to be included in the I-catalogues. The study was carried out as follows: First e-catalogues of many B2B sites were compared and analyzed from the viewpoint of customers, apparel manufacturers. Second, apparel manufacturers were interviewed to find out what causes the inconvenience, which prevent them to do B2B commerce. Third, on the basis of these n analysis, the researcher categorized information items of the e-catalogue. The apparel manufacturers were interviewed on the feasibility of the information items researcher suggested forth, With the results, we proposed an e-catalogue of 53 information items. Fifth, Another point of this study is that we tried to clarify the terminology for e-catalogue. Often textile traders and apparel manufacturers understand a same information with difference.

This study investigated the consumer review information considered important by consumers when making a purchase decision to buy apparel products online. Data were collected through focus group interviews. Eleven females in their 20s and 30s, who have extensive experience in reading consumer reviews posted on online apparel stores, participated in the study. The consumer review information considered important by participants is the information related to seven product attributes (size, fabric, design, color, sewing, price, and country of origin), seven benefits (functional, financial, esthetic, emotional, social, utilitarian benefits, and product value compared to price) of the apparel product and four store attributes (return/refund, delivery, reputation/credibility, and customer service). The findings from the study can serve as an important tool in developing survey questions in order to evaluate the quality of consumer review information and help online retailers plan methods to improve the quality of reviews.

We propose an optical Asynchronous Transfer Mode(ATM) switching system using free-space optics and an output buffer memory. The distributor system in the switching fabric was analyzed using the Huygens-Fresnel principle and lens transformation. For monochromatic illumination, a pattern similar to the Fourier transform of the input distribution was observed across the output plane. A spatially broadened intensity distribution across the the output plane can be expected when the system is illminated with a partially coherent, quasimonochromatic beam. Spatially coherent pulses as short as 100fs can propagate through the distributor without severe spatial broadening.
