Antenna Tracking System has been required core technology with special tracking algorithm, and it can be achieved by program tracking, step tracking, optracking, and monopulse tracking as well. Depend on tracking requirement we might be able to apply eligible tracking method in accordance with Geostationary and Inclined Orbit Satellite. Further, we should deeply consider two important factors in order to act up to customer expectation in quality and system performance including competitive price therefore we need maximized endeavor to upgrade not only tracking system performance, but reduction of product through engineering skill and R&D investment.

Since 2010, issues for data sharing and data exchanging in hospital information systems have been emerged. In order to solve the issues, standards should be applied to develop the systems and there should be no ambiguities between terminologies in the systems. In this paper, the terminology mapping system for narrative clinical records was implemented. The term mapping precision was 83.4%. This system could help to upgrade the text based clinical system and it would be expected to support for high quality clinical services.

The job design was frequently tried in many enterprises in order to give workers the job satisfaction, but there remains obscure about what kinds of human factors in job yield the satisfaction. This study is concerned with an experimental method for job design to account for such findings that work with conveyor gave workers unsatisfaction, and that enlarged job of work resulted in high job satisfaction.

최근 데이터 폭증으로 인한 시스템 및 스토리지 성능저하에 따른 upgrade와 용량증설 등의 요구가 거세지고 있어 단편적인 증설에 의한 해결보다는 보다 근원적이고 장기적 관점의 해결책이 요구되고 있다. 본 논문에서는 이에 대한 해결책으로 기업의 운영 중인 스토리지 시스템의 운영 상태와 데이터 가치 분석을 통한 정보수명주기 기반 스토리지 계층화 방안을 개선안으로 제시하고 구현하였다. 본 연구를 통해 체계화된 데이터 관리방안 수립과 정보수명주기 기반 계층화된 스토리지 시스템으로 재구성한 후 기존 대비 약 21%의 전체 Throughput이 개선되었고 장기적 관점에서 지속적인 품질유지 및 운영비용 절감에 매우 효과적임을 확인하였다.

Most of the sewage treatment plants in Korea are being operated by using the conventional activated sludge process. Recently, as the water criteria have been strict with regard to such main culprits of eutrophication, the existing sewage treatment plants are obliged to upgrade their treatment technology to meet the criteria. Under such circumstances, this study was aimed at analyzing the conditions of an existing sewage treatment plants in Korea, and thereupon, test its treatment performance for the actual sewage water by operating a pilot plant. When the pilot plant was operated with the NPR process at the capacity of $30m^3/day$, the average contents of BOD, $COD_{Mn}$, SS, T-N and T-P in the effluents were 7.0 mg/L, 9.7 mg/L, 5.1 mg/L, 8.0 mg/L and 0.23 mg/L, respectively, which were very stable in general. Accordingly, if the NPR process used for this pilot plant to upgrade the treatment technology for the sewage treatment plat could be adopted, the effluent water quality criteria effective beginning from 2008 would be met.

The origin of hospital accreditation in Korea is the Hospital Standardization Program of the Korea Hospital Association. Current accreditation program implemented by the Korea Institute for Healthcare Accreditation has succeeded in stimulating quality improvement activities of participating hospitals since its launching in 2010. However it has been criticized due to some unintended consequences of accreditation. In order to fully enjoy the benefit of the accreditation program in Korea, national efforts to expand accreditation scheme and coverage, upgrade accreditation standards, insure substantiality of accreditation process, provide consumers with more useful information, and strengthen the professional capacity of accreditation organization will be needed.

Presented in this paper is a methodology for combining a Bayesian statistical approach with Data Quality Objectives (a structured decision-making method) to provide increased levels of confidence in analytical data when approaching a waste boundary. Development of sampling and analysis plans for the characterisation of radioactive waste often use a simple, one pass statistical approach as underpinning for the sampling schedule. Using a Bayesian statistical approach introduces the concept of Prior information giving an adaptive sample strategy based on previous knowledge. This aligns more closely with the iterative approach demanded of the most commonly used structured decision-making tool in this area (Data Quality Objectives) and the potential to provide a more fully underpinned justification than the more traditional statistical approach. The approach described has been developed in a UK regulatory context but is translated to a waste stream from the Fukushima Daiichi Nuclear Power Station to demonstrate how the methodology can be applied in this context to support decision making regarding the ultimate disposal option for radioactive waste in a more global context.

Purpose: The purpose of the current study is to examine the effects of labeling information on the consumers' evaluation, with a focus on the effects of the three types of labeling information on the product quality. Research design, data and methodology: This study conducted a survey of the women respondents living in Gyeonggi province, Korea, during the time period of April 20th through May 30th, 2020. The sample data have been used to run regression analysis, reliability analysis, frequency analysis and factor analysis. Results: The empirical results are summarized as follows: 1) the labeling information on the brand image has a significantly positive effect on the consumers' evaluation about product's functional quality; 2) the labeling information on the product characteristics has a significantly positive effect on the consumers' evaluation about the expressed quality; and 3) the labeling information on the brand image has a significantly positive effect on the consumers' evaluation about the perceived quality. Conclusions: The conclusion is that the labeling information on product characteristics and the brand image is estimated to be statistically significant, therefore the Korean outdoor-wear industry are required to upgrade the information on the brand image and the product characteristics.

인터넷전화(VoIP), 인터넷TV(IPTV), 클라우드컴퓨팅(Cloud Computing), 스마트폰(Smart Phone) 등 스마트 IT 시대가 진전되면서 데이터(data) 전송이 폭증하고 있고, 서비스의 품질보장(QoS, Quality of Service)이 더욱 중요시되고 있다. 따라서 인터넷 트래픽(internet traffic)의 체증문제를 효율적으로 해소하고 망의 지속적인 업그레이드(upgrade)를 촉진하는 유인체계(incentive system)를 마련하는 것이 절실히 요청되고 있다. 그러나 한편에서는 인터넷망에서 어떠한 차별도 없는 '철저한 망중립성(Network Neutrality)'이 오늘날의 인터넷시대를 가능하게 한 일등공신임을 주장하면서 엄격한 망중립성을 법제화할 것을 요구하고 기존 제도를 고수할(Status Quo) 것을 주장하기도 한다. 따라서 본 연구는 인터넷환경의 변화를 살펴보고 망중립성 이슈를 분석한 후 선순환 인터넷생태계의 조성과 공정경쟁의 보장 및 이용자편익의 최대화를 위해서는 시장메커니즘의 핵인 가격기구 즉 요금시스템이 제대로 작동되어야 함을 제기한다. 그리고 바람직한 인터넷 사용요금의 부과방안으로 이용량과 QoS 보장여부 등 인터넷 이용형태에 따라 가격을 차별화하고 중장기적으로 네트워크 확충에 필요한 재원을 마련하기 위해 이부가격제(two-part tariff)를 실시하는 방안을 제시한다.

이 연구에서는 미국국회도서관의 CIP (Cataloging in Publication) 프로그램을 중심으로 서지 유틸리티를 통한 CIP 데이터 접근, 배포, 개선 및 활용의 관계를 고찰하였다. LC CIP 프로그램은 많은 출판사의 참여와 지속적 성장, CIP 서지정보의 품질에 대한 신뢰와 즉각적 접근을 위한 서지 유틸리티 종합목록 데이터베이스의 활용, 출판 후 서지정보의 완전성과 정확성 개선을 위한 품질제어 노력 등의 특성을 갖는다. LC와 OCLC와 같은 서지 유틸리티 사이의 협력은 국립중앙도서관의 '출판시 도서목록' 프로그램의 제한점에 대해 시사하는 바가 크다. 국립중앙도서관이 국가의 대표 서지기관으로서 출판예정 단행본에 제한된 CIP 데이터 뿐 아니라 모든 유형의 국내간행 신구간 자료에 대한 정확하고 완전한 서지 및 전거 레코드에 대한 국내 도서관의 요구를 충족시켜야 할 필요성이 지적되었다.
