  • 연안역은 산업, 가정 폐기물의 종착지이고 중기계금속산업과 석유화학산업단지가 다수 포진하고 있는 지역으로 환경에 유해한 물질들로 대기나 수질을 통해 오염되기 쉬운 여건을 가지고 있으므로, 쾌적한 환경을 위한 환경 모니터링이 불가피한 곳이다. 이에 연안역의 환경 모니터링을 위한 정확한 분석결과를 현장에서 측정할 수 있으며 사용자의 편의성을 제공하는 새로운 시스템의 도입이 시급한 실정이다. 연구개발 중인 수질 및 대기 모니터링 시스템은 전문지식이 필요 없이도 테스트의 수행, 테스트 자료, 분석결과의 관리를 위해 구축했는데 특히 사용자 인터페이스의 검량선, 정량분석을 중점으로 본 논문에서 서술하였다.

  • 지구 기후시스템의 중요구성인자인 해빙은 극지방과 고위도에 분포하는 특성상 위성을 통한 탐지가 활발히 수행되고 있다. 위성자료를 이용한 해빙탐지기법은 반사도와 휘도온도자료를 이용하며, 많은 연구에서 휘도온도자료를 통해 산출된 Ice Surface Temperature (IST)를 활용한 기법인 Moderate-Resolution Imaging Spectroradiometer (MODIS)의 해빙탐지기법을 활용하고 있다. 본 연구에서는 IST 산출과정이 생략된 단순하고 효율적인 동적임계값 기법을 활용한 해빙탐지기법을 제시하고자 한다. 동적임계값을 지정하기 위하여 해수의 어는점 이하의 화소를 대상으로 MODIS IST와 MODIS $11{\mu}m$ 채널의 휘도온도, Brightness Temperature Difference ($BTD:T_{11{\mu}m}-T_{12{\mu}m}$)의 상호관계를 분석하였다. 분석 결과, 세수치의 관계가 선형의 특징을 나타내었으며 이를 활용하여 임계값을 지정하였다. 청천역에서 지정한 임계값을 MODIS $11{\mu}m$ 채널에 적용하여 해빙을 탐지하였다. 또한, 본 연구의 해빙탐지기법의 성능을 검증하기 위해 MODIS Sea ice extent를 이용하여 정확도를 분석하였으며 그 결과, Producer Accuracy (PA) 99% 이상의 높은 정확도를 보였다.

  • In this work, our goal is to develop a fast and accurate power model of the ARM926EJ-S processor in the industrial design environment. Compared with existing work on processor power modeling which focuses on the power states of processor core, our model mostly focuses on the cache power model. It gives more than 93% accuracy and 1600 times speedup compared with post-layout gate-level power estimation. We also address two practical issues in applying the processor power model to the real design environment. One is to incorporate the power model into an existing commercial instruction set simulator. The other is the re-characterization of power model parameters to cope with different gate-level netlists of the processor obtained from different design teams and different fabrication technology.

  • 조선소에서 이루어지는 선박 건조는 용접에 의해 수행되고 있으며, 친환경선박에 대한 국제적인 요구에 따라 용접물량은 증가하고 있다. 용접부는 비파괴검사를 통하여 품질을 보증하고 있으며, 검사 정보를 나타내는 리포트는 인력이 설계된 도면을 확인하여 수작업으로 용접검사 리포트가 작성된다. 이 과정에서 소요되는 많은 공수와 인적오류로 인하여 손실이 발생하고 있다. 이러한 문제 해결을 위해 본 논문에서는 조선 전용 CAD 소프트웨어를 기반으로 설계된 데이터를 입력하여 용접검사에 관한 리포트가 자동으로 생성되는 시스템에 대하여 다룬다. 개발하는 시스템은 모델링의 도면으로부터 형상 데이터를 분석하여 부재 면의 확장을 통해 용접부를 판단 및 태그 넘버를 생성하고, 용접길이, 두께, 재질 등 검사에 필요한 정보를 자동으로 추출하는 기능을 제공한다. 시스템의 유용성을 검증하기 위해 시스템을 통해 추출된 검사 정보와 모델링 도면을 비교하여 일치하는 것을 확인하였다.

  • 이 논문은 데이터 큐잉 알고리즘과 의약품 빅데이터를 통해 약품 성분-성분 간의 정보와 질병-성분 간의 정보를 지원함으로써 의약품 다약제 복용 시 부작용이 발생 가능한 약물 정보를 사용자에게 제공하기 위한 시스템을 제안하고 구현한다. 또한, 의약품 성분에 더하여 복용이 금지된 의약품, 공급업체, 유통업체의 정보 등을 제공함으로써 의료 전문가뿐만 아니라 일반 사용자의 의약품 복용에 대한 불안감을 덜어줄 수 있다. 제공되는 대표적인 정보는 두 가지 약물 사이에서 일어나는 부작용, 특정 의약품의 주성분과 효능, 동일한 제약회사에서 제조된 의약품, 만성 질환 환자가 주의해야 할 약품 성분 정보이다. 앞으로, 희귀병 약이나 신약에 대한 정보를 수집하여 데이터를 업데이트하는 것이 필요하다.

  • This paper presents web-based virtual laboratory system for electronic and digital circuit experiments. Through our virtual laboratory, the learners will be capable of learning the concepts and theories related to circuit experiments and how to operate virtual experimental equipments such as multimeters, function generators, digital oscilloscopes, DC power suppliers and bread board etc. The proposed virtual laboratory system is composed of important components: Principle Classroom to explain the concepts and theories of electronic and digital circuit operations, Simulation Classroom to provide a web-based simulator to the learners, Virtual Experiment Classroom to provide interactive multimedia contents about the syllabus of off-line laboratory class, Assessment Classroom, and Management System. With the aid of the management System every classroom is organically tied together collaboration to achieve maximum learning efficiency. We have obtained several affirmative effects such as high learning standard, reducing the total experimental hours and the damage rate for experimental equipments.

  • Background: Recognizing that access to safe and healthy working conditions is a human right, the World Health Organization (WHO) calls for specific occupational safety and health (OSH) programs for health workers (HWs). The WHO health systems' building blocks, and the International Labour Organization (ILO), highlight the importance of information as part of effective systems. This study examined how OSH stakeholders access, use, and value an occupational health information system (OHIS). Methods: A cross-sectional survey of OSH stakeholders was conducted as part of a larger quasi experimental study in four teaching hospitals. The study hospitals and participants were purposefully selected and data collected using a modified questionnaire with both closed and open-ended questions. Quantitative analysis was conducted and themes identified for qualitative analysis. Ethics approval was provided by the University of Pretoria and University of British Columbia. Results: There were 71 participants comprised of hospital managers, health and safety representatives, trade unions representatives and OSH professionals. At least 42% reported poor accessibility and poor timeliness of OHIS for decision-making. Only 50% had access to computers and 27% reported poor computer skills. When existing, OHIS was poorly organized and needed upgrades, with 85% reporting the need for significant reforms. Only 45% reported use of OHIS for decision-making in their OSH role. Conclusion: Given the gap in access and utilization of information needed to protect worker's rights to a safe and healthy workplace, more attention is warranted to OHIS development and use as well as education and training in South Africa and beyond.

  • Under the rapid change of business circumstance to E-business, CRM is one of the major strategic choices to reinforce the relationship with customers. In this point, this study attempts to understand the relationships among the quality of CRM and the variables of post adoption on the innovation diffusion theory. With integration of information system success model and innovation diffusion theory, it developed a research model and several hypotheses focusing on CRM performance of post-adoption. To testify the hypotheses, it conducted a survey on insurance industry and performed a statistical analysis for the research model with structure equation model. The results show that the factors of CRM quality (system, service, and information) have significant relationships with level of CRM usage and satisfaction. And the relationships between satisfaction and CRM performance and between CRM performance and intension of CRM extension are found as statistically significant.

  • The purpose of constructing university information system is for improvement in diversification and throughput of information, streamlines business processes, rapid exchange of information, sharing of information, decision-making information, and securing educational facilities. Similar to business information technology system, university information system does not have a review system for sharing and overlapping investment of information. Due to the lack of project management for outsourcing and vulnerability of system suitability, system audit is absolutely needed for the university information system. This paper especially focuses on an operational phase in the audit of university information system. Additionally, we proposed operating model and checklists of the university information system based on Management Guidelines of ITIL V3 Operational and Information System. We derived the checklists of operation audit by each domain of service strategy, service design, service transition, service operation, and continual service improvement. As the result, this study appear to have more than average satisfaction the suitability results were.

  • This survey was conducted to give the basic information and temperature and humidity variation by cooling systems in dairy farms in Korea. A total of 36 farms were surveyed in Gyeonggi province with the general information of farms such as milk production, and milk quality, types of cooling systems, and its operation method of dairy farms. All of surveyed farms have cooling fan and some have 1 more cooling systems such as sprinkler, foggy systems, ventilation duct, and shower system. Although the indoor THI of cow house was decreased by either ventilation duct or foggy system during hot season, the range belongs to mild heat stress scale for dairy cows.
