최근 들어서 상황인식 시스템은 차별화 된 전자 시장을 개척하기 위한 유망한 기술로 인정되고 있다. 상황인식 컴퓨팅을 통해 구현되는 시스템은 사용자의 현재 상황을 자동적으로 센싱하여 그의 환경을 자동적이고 심도 있게 이해함으로 이음매 없고 기민한 개인화 서비스를 제공하는 것이 목적이다. 이러한 목적을 달성함에 있어서 특정 정보시스템이 얼마나 상황 정보를 잘 인식하고 활용하느냐는 것이 매우 중요하겠다. 그러나 비록 상황인식 시스템의 수준에 대한 언급들은 그 동안 많이 이루어져왔지만 본격적이고 구조적인 평가 방법론이 제안되어오지는 못해왔다. 따라서 본 논문의 목적은 상황인식 시스템을 평가하기 위한 구조적인 방법을 다단계 방법론으로 제안하는 것이다. 제 1단계에서는 특정 정보시스템이 과연 상황인식 시스템으로 분류될 수 있는지를 평가하는 요건분석을 수행하고, 제 2단계로는 요건 분석을 통과한 시스템에 대해 장비협업정도, 이동성의 정도, 내재성의 정도라고 하는 세 가지 차원으로 평가하여 상황인식 시스템의 수준을 평가한다. 이를 위해서 시스템 아키텍처에 기반 한 장비협업도(Device Collaboration Diagram, DCD)라는 것을 제안하였다. 그리고 각 프로젝트의 개발전략을 도출하기 위해 시스템의 수준과 준비도라는 두 가지 차원으로 종합적 수준을 평가하였다. 또한 본 방법론의 가능성을 증명하기 위해 최근에 개발되고 있는 실제 프로젝트들을 대상으로 평가를 수행하였다.

This paper attempts to discuss the complex nature of social contexts regarding English language education in Korean middle school and to demonstrate the affective factors that should be considered to find appropriate approaches within the context. To do this, a questionnaire survey was conducted among 85 middle school students regarding learners' motivation, and attitudes toward EFL learning. Additionally, teachers in secondary school were asked about the general circumstances of English language education. Findings indicate that in spite of the participants' high instrumental motivation, they rather show a negative attitude toward English learning. This paper intends to raise practitioners' attention to the fact that the effect of learners' affective variables on EFL learning seems distinctive depending on the host country's EFL contexts.

Environmental differences across countries such as socio-cultural, political, economic, and technological differences require business strategies of multinational corporations to vary business practices across regions. Despite the keen awareness of the necessity for strategic adaptation to local context, IS management and strategy tend to remain similar across countries. One of the reasons is to maintain the stability and compatibility of information technology infrastructure. After a careful observation of retail business practice, this study finds IS strategy should also be highly responsive to the local context. This study shows how information resources including systems architecture, processes, human resources, and national context are interlinked together. Despite global excellence in general systems management, failure in such alignment can be a serious problem in extending competitive advantages across regions. This study aims to reveal issues to be taken care of in order to accomplish global technological alignment. Results of this study provide senior management with guidelines and a framework for aligning IT with regional strategic thrust that can improve local responsiveness of multinational companies.

The performance of the statistical context-sensitive spelling error correction depends on the quality and quantity of the data for statistical language model. In general, the size and quality of data in a statistical language model are proportional. However, as the amount of data increases, the processing speed becomes slower and storage space also takes up a lot. We suggest the improved statistical language model to solve this problem. And we propose an effective spelling error candidate generation method based on a new statistical language model. The proposed statistical model and the correction method based on it improve the performance of the spelling error correction and processing speed.

This research focused on the examination of a "Goodness of Fit" model with reference to the interaction effects of temperament and context. Two hundred forty 5th graders from urban and rural areas were administered the EAS (Emotionality, Activity, Sociability) and the Perceived Competence scales. The degree of satisfaction of mothers with their children's temperament was assessed for the context measure. Results of hierarchical multiple regression analyses showed that the interaction of children's emotion and mothers' satisfaction with children's emotion explained perceived social competence and general self-worth. This result supported the goodness of fit model. However, interaction effects were not found in children's perception of cognitive and physical competence. Also, children's activity and sociability showed strong main effects on perceived competence. It implies that activity and sociability should be applied to the personological model. The implication of the findings for following studies of goodness of fit model were discussed.

Human reliability assessment (HRA) is conducted on the unspoken premise that 'human error' is a meaningful concept and that it can be associated with individual actions. The basis for this assumption it found in the origin of HRA, as a necessary extension of PSA to account for the impact of failures emanating from human actions. Although it was natural to model HRA on PSA, a large number of studies have shown that the premises are wrong, specifically that human and technological functions cannot be decomposed in the same manner. The general experience from accident studies also indicates that action failures are a function of the context, and that it is the variability of the context rather than the 'human error probability' that is the much sought for signal. Accepting this will have significant consequences for the way in which HRA, and ultimately also PSA, should be pursued.

This paper investigated students' and teachers' attitudes toward L2 grammar in EFL learning context. In a study in which attitude was viewed as consisting of three different components such as cognitive, affective, and behavioral, questionnaire developed on the basis of such a view of attitude was used as a data collection method. The results of the study indicated that in general, both students and teachers were similar to each other in their attitude toward L2 grammar. Among the findings, most important, two groups were shown to fully understand the important role of grammar in L2 learning. Another finding was that despite the 6th national curriculum for English education, our English class was still dominated by grammar-centered instruction. Also it was shown that the way teachers had been taught L2 grammar had a considerable effect on the way they would instruct it in their future classes. Based on these findings, some suggestions were offered for effective grammar pedagogy in EFL context.

In general, Taek-li-ji is noted for its reliable source in studies on the old korean culture. But when we examine it in detail, we can find its contrary propositions with regard to the context ; for the thematic question of the good place to settle, that is the leitmotiv of Taek-li-ji, opinion, in consideration of the place of good settlement, has the author the conclusion ; nowhere, but by means of "I Ging" can be found a good one - place of no place. In the text, we find some other questionable points. In means that the content of this book must be to make understandable and we need a solution of the contradiction in context. 1 think it might be intended by the author. In this study I have tried, the intention of the author to find and the context to review, in order to interpretate the text and to resolve its contradiction. And I have earned a hidden opinion of the author, the second intention of the book.

The environmental differences between training and testing mode are generally considered to be the critical factor for the performance degradation in speaker recognition systems. Especially, general speaker recognition systems try to get as clean speech as possible to train the speaker model, but it's not true in real testing phase due to environmental and channel noise. So in this paper, the new method of weighting the frame-based likelihood according to frame SNR is proposed in order to cope with that problem. That is to make use of the deep correlation between speech SNR and speaker discrimination rate. To verify the usefulness of this proposed method, it is applied to the context dependent speaker identification system. And the experimental results with the cellular phone speech DB which is designed by ETRI for Koran speaker recognition show that the proposed method is effective and increase the identification accuracy by 11% at maximum.

본 연구는 기업가정신에 있어 성별 간 차이가 나타나는 현상 자체가 아닌 기업가정신의 성별 차이를 발생시키는 사회적 맥락의 영향을 확인하는 데에 초점을 둔다. 구체적으로 본 연구는 글로벌 기업가정신 트렌드 리포트(GETR)의 20개국 데이터를 사용하여 사회적 맥락이 성별과 기업가정신 간 관계에 미치는 조절효과를 검증하였다. 사회적 맥락의 함의와 관련된 가설검증을 위하여, 본 연구에서는 Hofstede의 문화차원 요인인 권력 거리, 개인주의, 남성성, 불확실성 회피와 제도적 요인인 양성평등, 사회보장을 사회적 맥락을 반영하는 구체적 변수로 사용하였다. GLM을 사용한 실증분석 결과 성별은 기업가 정신에 독립적으로 영향을 미치지 않았으며, 성별은 각각 권력 거리, 개인주의, 불확실성 회피, 양성 평등, 사회 보장 변수와 상호 작용하여 유의한 영향을 미치는 것으로 나타났다. 이와 같은 본 연구의 결과는 기업가정신의 성별 차이가 각 성별에 내재된 고유의 특성에 기인한 것이 아니라, 개인이 속한 그 국가의 사회적 맥락 수준에 따라 나타날 수 있음을 시사한다.
