The purpose of this paper is to propose a new type of NPI licensing context through French subjunctive and ne expletif. The distribution of NPIs on previous studies does not exactly correspond to negative function types. French subjunctive and ne expletif are good guidelines for reclassifying NPI licensing context. My classification is by a hierarchy of strength in negative force: overtly negative proposition > negative entailment > negative implicature. A new type of NPI licensing context is: (i) I-domain for negative implicature (ⅱ) E-domain for negative entailment and (ⅲ) overt negation.

Ontology has many merits such as high expression power and extensibility etc. and there are some suggestion on development of ubiquitous environment using ontology. For collecting and analysing the context information in ubiquitous environment, we need a context-awareness system. For these reason, some context-awareness systems have been developed using ontology, but they have insufficient representation power of context information and are independent to domain. In this paper, we define the context type to improve the extensibility of context framework, and develop the context ontology adopting the defined contort type to represent or inference various context information. We define the ontology to be easily adopted the and domain. Also, we use SWRL to represent numerical formulas and Horn-Logic expression.

Objective: The present study was to improve the graphic user interface (GUI) of a military computer-based training (CBT) system in terms of usability. Background: Existing studies have focused on usability evaluation of a particular GUI type such as sequence, hierarchy, or context type; however, few research has been conducted which identifies preferred GUI features based on a comparative analysis of different GUI types. Method: A comparative evaluation was conducted by 9 CBT design experts using a 7-point scale (1: very low, 4: neutral, and 7: very high) on hierarchy and context GUI types of a military CBT system in terms of 10 usability criteria. Then, preferred features of the hierarchy and context types being accommodated, a new GUI was developed and validated by 22 CBT users. Results: While the hierarchy type was found preferred by 1.6 times in terms of controllability to the context type, the opposite was found in terms of attractiveness, simplicity, and responsiveness by 0.6, 0.8, and 0.8 times, respectively. The proposed GUI was found superior to the hierarchy and context types in terms of accessibility and informativeness by more than 1.5 times, but inferior to the hierarchy and context type in terms of simplicity by 0.6 and 0.9 times, respectively. Conclusion: The new GUI developed by accommodating the preferred features of the hierarchy and context types improves usability in terms of accessibility and informativeness except simplicity. Application: The comparative analysis of various GUIs can be applied to develop an improved GUI in a systematic manner based on preferred features of the existing GUIs.

유비쿼터스 컴퓨팅 환경에서 가장 중요한 이슈중의 하나는 상황인지(Context-Aware)가 가능한 환경을 구축하는 것이다. Context-Aware 환경이 구축되면 주변의 상황을 감지하여 특정 어플리케이션을 실행한다거나, 시스템을 재구성하는 등의 일을 수행할 수 있다. 그동안 이런 상황인지가 가능한 환경을 Context-Aware 미들웨어를 통해 구현하려는 연구가 많이 수행되었다. Context-Aware 미들웨어를 구현하기 위해 무엇보다도 중요한 것은 실제 세계의 다양한 종류의 상황을 컴퓨팅 환경에 적용시키는 것이다. 그러나 현실 세계에서 Context의 종류는 거의 무한하다고 할 수 있다. 기술이 발전하게 되면서 인지 가능한 Context의 종류도 무한정 늘어나게 될 것이다 또한 실제 세계에서의 Context들은 추상적인 경우가 많이 있다. 그러나 Context가 추상적이라 해도 다른 Context 정보를 이용해서 구체화 할 수 있다. 이런 과정을 위해 Conte지들을 계층적으로 관리해야 할 필요가 있다. 본 논문에서는 Context-Aware 미들웨어를 구현할 때 Context들의 이런 여러 가지 특성들을 고려해서 Context Type을 관리랄 수 있는 하나의 객체를 제안하고, 다른 방법들과 비교, 분석해 보았다.

유비쿼터스 컴퓨팅 환경은 공통적으로 재사용 가능하고, 확장성이 강력한 컨텍스트 모델이 필요하다. 본 논문에서는 엔티티(Entity), 컨텍스트 타입(Context Type), 값(Value)으로 구성된 트리플을 기반으로 한 유비쿼터스 컴퓨팅 환경의 컨텍스트를 모델을 제안하였다. 컨텍스트 정보를 주어, 동사, 목적어에 해당하는 (Entity, Context Type, Value) 트리플로 표현함으로써 재사용성과 확장성을 제공한다.

This study tries to find the differences in attitude towards advertisement and corporate image according to the context of article in web contents, banner advertisement exposure and news type. The findings of this study are as follows. First, interaction effect between the context of Internet article on social contribution activity and attitude towards advertisement was confirmed. When the context of Internet article was negative, the news type that provides a photo with the article was more effective for the attitude towards advertisement. It is estimated that when a photo is provided with an Internet article for social contribution activity, the level of crowdedness increases and accordingly the negative context of the Internet article is cancelled out. Second, interaction effect between news type and advertisement type of social contribution activity article and attitude towards advertisement was confirmed. In the news type that provides a photo with an Internet article, corporate advertisement was more effective for attitude towards advertisement than product advertisement. Third, interaction effect between the news type of social contribution activity and corporate image according to advertisement type was confirmed. In the news type that provides a photo with an Internet article, product advertisement was more effective for corporate image than corporate advertisement.

This study proposed a framework to clarify a viewpoint of quality problems, and to consider reliance, of context information in ubiquitous computing environments. The framework is structured as a sequence of steps in measuring the quality of context information. The first step in measuring the qualify of context information is to determine users of the context information. This is important because the type of users or applications determines the type of context information and thus the methods of measuring the qualify dimensions and the thresholds for evaluating the quality of context information. The other steps include methods for measuring each quality dimensions to allow quantitative evaluation of quality, establishing acceptable quality targets. We selected accuracy, completeness, up-to-dateness, access security, and representation as quality dimensions and proposed their measurement methods and concrete procedures. We enabled objective evaluation of quality level through proposal of methods suitable to quality measurement of context information.

In this paper we first introduce a Carleson inequality and study the generalized form of Carleson inequality in the context of spaces of homogeneous type. The previous inequality is known to play important roles in harmonic analysis.

This study is to describe the changes of spatial structure of Korean traditional housing in urban context with the following preconditions. Firstly, Chosun Hanyang's urban housing should be classified as it's own type. Secondly, Chosun's traditional housing accomplishes a complete urban housing type in Japanese colonial period through the stream of time. And the purpose of this study is as followings. First is to find out the process of changes of urban housing in urban context from the latter period of Chosun Dynasty to 1960's. Second is to find out the origin of spatial structure of urban house which is being kept throughout the above changes. Third is to find out the unique characteristics of urban house and the fundamental differences with folk houses in province.

An attention task, in which context information should be extracted from the first presented pattern, and the recognition answer of the second presented pattern should be generated using the context information, is employed in this paper. An Elman-type recurrent neural network is utilized to extract and keep the context information. A reinforcement signal that indicates whether the answer is correct or not, is only a signal that the system can obtain for the learning. Only by this learning, necessary context information became to be extracted and kept, and the system became to generate the correct answers. Furthermore, the function of an associative memory is observed in the feedback loop in the Elman-type neural network.
