Climate change is an important issue, with many researches examining not only future climatic conditions, but also the interaction of climate and air quality. In this study, a new version of the emissions processing software tool - Python-based PRocessing Operator for Climate and Emission Scenarios (PROCES) - was developed to support climate and atmospheric chemistry modeling studies. PROCES was designed to cover global and regional scale modeling domains, which correspond to GEOS-Chem and CMAQ/CAMx models, respectively. This tool comprises of one main system and two units of external software. One of the external software units for this processing system was developed using the GIS commercial program, which was used to create spatial allocation profiles as an auxiliary database. The SMOKE-Asia emissions modeling system was linked to the main system as an external software, to create model-ready emissions for regional scale air quality modeling. The main system was coded in Python version 2.7, which includes several functions allowing general emissions processing steps, such as emissions interpolation, spatial allocation and chemical speciation, to create model-ready emissions and auxiliary inputs of SMOKE-Asia, as well as user-friendly functions related to emissions analysis, such as verification and visualization. Due to its flexible software architecture, PROCES can be applied to any pregridded emission data, as well as regional inventories. The application results of our new tool for global and regional (East Asia) scale modeling domain under RCP scenario for the years 1995-2006, 2015-2025, and 2040-2055 was quantitatively in good agreement with the reference data of RCPs.

A simulation model for the estimation of cutoff connection rate in the asynchronous transfer mode (ATM) switching system under multimedia traffic environments is presented. The simulator is developed by the integration of the AweSim tool with user-written C++ routines that model the internal structures of operational details of the switching system. For the case study, the simulator is applied to the ATM switching system developed by Electronics and Telecommunications Research Institute (ETRI) to compare design alternatives according to the cutoff connection rates.

실 제품을 제작하기 전 컴퓨터를 이용해 프로토타이프를 제작해 미리 제품은 평가하는 방법이 널리 사용되고 있다. 프로토타이핑 작업으로 제품의 외관을 미리 평가하는 부분은 이미 실효성을 입증 받았다. 그러나 사용자 인터페이스(User Interface) 디자인 부분에 대한 평가에서는 아직 그 유효성에 대한 연구가 충분하지 못한 형편이다. 본 연구는 프로토타이핑 방법에 의한 사용자 인터페이스 디자인 평가가 과연 적절한 방법이 될 수 있는 지에 대해 실험적 검정을 수행하였다. 대상이 되는 제품으로 전자렌지를 선택했으며 이를 컴퓨터를 이용해 프로토타이프를 제작했다. 12명의 피실험자들을 나누어 실 제품과 프로토타이프에 대한 사용성 평가를 수행하였고 그 결과를 분석하였다. 분석 결과 실 제품과 프로토타이프 사이에 작업성공률, 작업수행시간, 버튼 조작 회수 등에 차이가 있는 것으로 밝혀졌다. 이는 아직도 프로토타이핑 방법이 사용성 평가 도구로 사용하기에는 보완해야할 점이 많이 있다는 것을 의미한다. 토의에서는 이에 대한 원인 규명과 문제점 해결을 위한 보완 사항 등을 제시하였다. 본 연구의 결과는 현장에서 래피드 프로토타이핑 방법을 적용해 제품의 사용성 평가를 수행하려는 디자이너들에게 도움을 줄 수 있을 것이다

본 연구는 초등학교 교과 커리큘럼의 일부로, 교육용 게임을 개발 시 필요한 "게임제작 방법론"을 서울 사립 초등학교 역사수업에 도입 된 교육용 게임 개발 사례를 중심으로 소개하고자 한다. 교육용 게임 개발 시 학습효과를 높이는데 도움을 주는 스마트 디바이스와 같은 매체들을 학습 도구로 정의하고, 플레이어를 사용자로 간주하여, 기존의 게임 개발 프로세스와는 다르게 학생과 교사를 최종 사용자와 의사 결정자라는 관점에서 UX 디자인 중심의 개발을 실행하였다. 게임의 플랫폼은 UX디자인 중에서도 사용자를 위한 서비스 경험 디자인 중심의 개발 과정을 도입하였다. 이를 통해 의사 결정권자인 선생님들이 게임이라는 학습 도구를 쉽고 효율적으로 사용하도록 게임 플랫폼 설계 단계부터 사용자 중심으로 디자인하였다. 최종 결과물인 게임과 게임 플랫폼을 통해 교사들이 의도한 학습 방향으로 학습 진행이 원활하게 이루어지도록 유도하여, 학습효과 역시 최종 사용자인 아동들의 학습 동기와 성취도를 높여 주고자 하였다. 본 연구는 해당 사례를 통해 국내 사립학교 학습 환경과 교과에 도입 가능한 수준의 교육용 게임 모델을 제시 하고, 이를 위한 실질적인 교육용 게임 개발 방법론을 제안 하고자 한다.

Business Intelligence (BI) system is a strategic tool that presents an analytical perspective about business and external environments. Even though its strategic value was well known, users often avoid using it or adopt it ceremonially. In fact, over 50 per cent of BI projects worldwide are reported to end in failure. Such an unexpectedly lower success rate has been a key issue in BI studies. In order to enhance a proper use of information systems, MIS field provided a number of theoretical constructs. One example is Goodhue & Thompson's Task-Technology Fit (TTF). In addition, internalization, the degree to which people make their own effort to modify behavior, was recently suggested as another important determinant of use. Though in MIS community both TTF and internalization proved to be a key determinant of system use, there has been not much study aiming to discover antecedents influencing these constructs. In this study we assert that user participation should be highlighted in BI projects. Especially, we emphasize user participation at the phase of feasibility study that is mainly conducted to determine whether a BI system is essentially necessary and practicable. Our research model employs participative feasibility study as a major antecedent for TTF and internalization that consequently will lead to user satisfaction and actual use. This model was empirically tested on 121 BI system users. The result shows that user participation in feasibility study is positively associated with TTF and internalization, each being related to user satisfaction and system use. It implies that, if an organization has BI users get involved in strategic feasibility study phase, the BI system would turn out to fit users' tasks and, furthermore, users would put more efforts spontaneously in order to use it properly.

This paper proposes a semiautomatic vertebra segmentation method that overcomes limitations of both manual segmentation requiring tedious user interactions and fully automatic segmentation that is sensitive to initial conditions. The proposed method extracts fence surfaces between vertebrae, and segments a vertebra using fence-limited region growing. A fence surface is generated by a deformable model utilizing valley information in a valley emphasized Gaussian image. Fence-limited region growing segments a vertebra using gray value homogeneity and fence surfaces acting as barriers. The proposed method has been applied to ten patient data sets, and produced promising results accurately and efficiently with minimal user interaction.

The objective of this study was to criticize the model house of apartment and suggest a evaluation model which could be used as an effective tool. The evaluation model had been developed based on the theoretical framework suggested by previous results of research related on housing design, which comprised the following four components : 1) the paradigm of future home and life-style, 2) marketing effects of housing developer, 3) goals and principles of housing design and 4) results of user-preferences study, an evaluation model was suggested as a preliminary form which would be modified in detail after series of tests in the field. The evaluation model will be used to provide standardized criteria for the quality of model houses, and eventually help to improve the quality of apartment housing design by balanced information from theorist, user and developer.

This study aims at defining the concept of OPAC, tracing of research trends and development of it, and clarifying various methods of subject access and patterns of bibliographic searching in OPAC as well as strategies for improving to implement online catalogs. Although OPAC is so far the most user-friendly bibliographic searching method, there are still a lot of issues including online subject access in particular. Therefore a more effective and useful method for computer end-users have to be developed, for instance, improvement of an indexing system, a n.0, pplication of the classification system as a searching tool, a new design and construction of standardized thesaurus, betterment of user interface, introducing of expert system into bibliographic searching, establishment of subject authority file. Those would raise the success-rate of users seeking bibliographic information in the library catalogs. Korean libraries are in very early stage of OPAC implementation so that every efforts and concerns to improve strategies and techniques for subject access to OPAC have been strongly asked.

This research presents new type of remote monitoring and control solution of PLC that can be used bi-directional and efficient management of factory automation through internet. This system has client/server architect for information handling between PLC and remote computer where a user can control and monitor target PLC. Actually the authors redirect RS232C connection between PLC and server computer into Internet connection between PLC and remote client computer using supplied PLC tool program So user feel like in front of PLC panel when he operates remote PLC through Internet. Each client/server program is constructed with Java language for security. In this paper the internet-based remote control system was proposed and proved validity by being applied to redirection of PLC control for factory automation.
