When we are visiting unfamiliar huge public places, it is hard to know what, how, and where to go. For solving these problems, we have suggest a user guide system, and a knowledge model which is built to support the system. High intelligence guidance system needs to react the user's context more spontaneously, which could be obtained when a system aware both the location and process coordinately. In this paper, we will show how our knowledge model is designed to enable the system to interpret simultaneously both of them.

Despite the significance of functional thinking at the elementary school level there has been lack of research on teachers who play a major role in making students be engaged in functional thinking. This study surveyed 119 elementary school teachers to investigate their knowledge of functional thinking for teaching. A written assessment for this study was developed with a focus on the knowledge of mathematical tasks and instructional strategies to teach functional thinking. The results of this study showed that many teachers were able to design tasks corresponding to both the additive relationship and the multiplicative relationship, and to justify some strategies to promote functional thinking. However, some teachers had lack of understanding with regard to the core ideas of functional thinking. Based on these results this study is expected to suggest implications on what aspects of knowledge are further needed for elementary school teachers to promote students' functional thinking.

To obtain a correctly translated sentence in a machine translation system, we must select target words that not only reflect an appropriate meaning in a source sentence but also make a fluent sentence in a target language. This paper points out that a source language word has various senses and each sense can be mapped into multiple target words, and proposes a new translation disambiguation method based on this 'word-to-sense and sense-to-word' relationship. In my method target words are chosen through disambiguation of a source word sense and selection of a target word. Most of translation disambiguation methods are based on a 'word-to-word' relationship that means they translate a source word directly into a target wort so they require complicate knowledge sources that directly link a source words to target words, which are hard to obtain like bilingual aligned corpora. By combining two sub-problems for each language, knowledge for translation disambiguation can be automatically extracted from knowledge sources for each language that are easy to obtain. In addition, disambiguation results satisfy both fidelity and intelligibility because selected target words have correct meaning and generate naturally composed target sentences.

In order to overcome the problems with first generation expert systems at the symbol level, recently various knowledge level development techniques of second generation expert systems have been proposed. But, these techniques are conceptual modelling techniques. This paper modifies and complements these conceptual modelling techniques and proposes a Task Object Modelling (TOM) technique as a practical knowledge level expert system development technique. This paper defines a Task Object(TO) as a knowledge unit consisted of a goal, execution conditions, behaviour knowledge, and so on. And, we define a Task Object Diagram(TOD) to depict structual, dynamic, and functional aspects of TO easily. We also define Inference Types as basic units to describe behaviour knowledge of TOs. In order to utilize the proposed TOM technique as not a simple conceptual modelling technique but a practical second generalion expert system development technique, we implement a TOD editor, a TO editor, and TO processing algorithm based on the state of TOs. Also we implement a Inference Types Library, in which each inference type is corresponded to an IRE(Jntelligent Rules Element) method, to transform the defined inference types into IRE methods automatically.

기후변화로 인하여 가뭄은 그 위험성이 점차 높아질 것으로 예상되고 있다. 잠재적 대규모 가뭄피해를 사전에 예방하기 위해서는 가뭄에 보다 효과적으로 대응하기 위한 방안을 마련하는 것이 필요하며, 국가적 수자원 관리를 넘어선 국민 전반이 가뭄 심각성을 인지하고 적합한 대응을 하도록 유도하는 것이 중요하다. 기상, 수문, 농업 등 가뭄 발생의 다양한 측면들을 표현한 여러 가뭄지수 및 정보가 이미 생산되고 있으므로, 이러한 정보를 국민에게 제공한다면 국민이 가뭄의 심각성을 인지하고 물 절약 등의 행동에 동참하도록 하거나 농민의 경우 사전에 대처 방안을 마련하도록 하는 등, 공급측면에서의 수자원 관리 뿐만 아니라 수요 측면에서의 대응도 가능하게 될 것이다. 하지만 현재 제공되는 가뭄지수 및 정보는 전문적 지식이 있는 의사결정자 및 연구자 등을 위한 것으로, 일반 시민이 이러한 정보를 통해 가뭄의 상황을 이해하고 해석하여 그에 따른 행동을 하기란 어려운 것이 사실이다. 따라서, 본 연구에서는 국내 가용한 가뭄지수 및 정보로부터 국민이 체감할 수 있으며, 적절한 행동을 하도록 설득할 수 있는 가뭄정보 생산 방안을 도출하고자 한다. 사회과학적 이론, 포커스그룹 인터뷰 및 설문조사를 통하여 국민의 가뭄정보에 대한 인지 및 이해 특성을 파악하고, 시민자문단을 통하여 직접적으로 국민에게 현재 가용한 가뭄정보를 제공하고 어떻게 바라보는지 분석함으로써, 국민이 체감 가능한 가뭄정보의 방향을 제안하였다. 또한 현재 가뭄에 대한 뉴스 등이 어떠한 방식으로 생산되고 유통되는지를 분석하여 이로부터 사회과학적 측면에서 국민을 설득하기 위한 보다 효과적 방안을 제시하였다. 결과적으로 국민이 가뭄의 상황을 인지하고, 국가적 차원의 가뭄 대응의 필요성을 이해하며, 물 절약 등의 행동을 하도록 설득하는 것이 가능하게 되어, 점차 심각해져가는 가뭄에 효과적으로 대응할 수 있을 것으로 판단된다.

This case study shows constructing the knowledge-based system using a rule-based approach for detecting illegal transactions regarding money laundering in the Korea Financial Intelligence Unit (KoFIU). To better manage the explosive increment of low risk suspicious transactions reporting from financial institutions, the adoption of a knowledge-based system in the KoFIU is essential. Also since different types of information from various organizations are converged into the KoFIU, constructing a knowledge-based system for practical use and data management regarding money laundering is definitely required. The success of the financial information system largely depends on how well we can build the knowledge-base for the context. Therefore we designed and constructed the knowledge-based system for anti-money laundering by committing domain experts of each specific financial industry co-worked with a knowledge engineer. The outcome of the knowledge base implementation, measured by the empirical ratio of Suspicious Transaction Reports (STRs) reported to law enforcements, shows that the knowledge-based system is filtering STRs in the primary analysis step efficiently, and so has made great contribution to improve efficiency and effectiveness of the analysis process. It can be said that establishing the foundation of the knowledge base under the entire framework of the knowledge-based system for consideration of knowledge creation and management is indeed valuable.

As creative economy gets attention, the capabilities of transforming creative ideas into intellectual property and utilizing it commercially have become important than ever before. Korea is lack of the capabilities of utilizing intellectual property compared to those of accumulating it. This paper focuses on the strategic implication of an injunctive relief, which has a far-reaching impact on firms' business strategies as well as national industrial competitiveness because losers in lawsuits are expelled from markets. It analyzes the Samsung-Apple global IP lawsuits about smartphones and tablet PCs, which have expanded into 9 countries since 2011 when the Apple filed the IP lawsuit against Samsung in the US for the first time. In particular, this paper analyzes the requirements to get the permanent injunctive relief in the lawsuits of intellectual property from reviewing the ruling in the court of the US in 2012 and draws some implications from the perspective of business/industrial strategies. This paper has some limitations in that the lawsuit are still ongoing and it is the first attempt to find out the clue that connects legal and strategic issues in the rulings. Regardless of the limitations, however, this paper expects to contribute to raising the issues as to the importance of harmonizing the capabilities of managing technology with law, in order to survive under the era of creative economy.
