Web usage mining is a method to extract meaningful patterns based on the web users' log data. Most existing patterns of web usage mining, however, do not consider the users' diverse inclination but create general models. Web users' keywords can have a variety of meanings regarding their tendency and background knowledge. This study evaluated the extraction web-user's pattern after collecting and analyzing the web usage information on the users' keywords of interest. Web-user's pattern can supply a web page network with various inclination information based on the users' keywords of interest. In addition, the Web-user's pattern can be used to recommend the most appropriate web pages and the suggested method of this experiment was confirmed to be useful.

Incheon International Airport(IIA) is planned to open in about two years. Korean government has an ambition to make IIA a major hub airport in Northeast Asia. The most essential and required condition for an airport to be a successful hub airport in a certain region is to have more efficient flight service network than the other airports in the same region. IIA should compete with Japanese airports to be a major hub in Northeast Asia because Japanese government also has a plan to expand greatly the airport capacity in Tokyo area and Kansai airport in Osaka. It is necessary for both IIA and Korean national air carriers to compose efficient flight service network considering hub competition with Japanese major airports. As the liberalization of international air transport industry would give more marketing freedom to airlines, they would plan the flight service network and flight schedule based on market analysis instead of governmental regulations. In the economically liberalized environment, it is very required to analyze air passengers' flight choice behaviour in order to induce other carriers and passengers through IIA's attractive flight service network. Disaggregate model is more appropriate than aggregate model to analyze consumers' behaviour. The information derived from disaggregate choice model of air passengers could be utilized in devising efficient flight network and schedule plan. Value of travel time or trade off ratio between flight frequency and travel time which could be estimated from discrete choice model could be utilized for scheduling an efficient flight plan for airlines and composing efficient flight service network for IIA.

지난 10년 동안 구미에서는 부모-아동 관계 영역에 혁신을 가져왔다. 특히 부모-아동 애착이론의 획기적인 변화로 가족 중심 출산 경험을 강조하고 있다. 과거에는 남편이 아내의 출산에 참여하던 것이 타부시되어 왔지만 애착의 개념이 대두되면서 남편도 출산에 함께 참여하도록 고려하여 임신에서부터 부부가 함께 이 과업을 완수하도록 모든 환경을 변화시키고 있다. 애착이론은 다양하여 정신분석이론, 학습이론, 인지발달이론과 동물 행동학적 측면에서 이해되고 있다. 다양한 이론적 배경과 개념들을 가지고 아버지-아동의 애착 및 유대관계에 대한 연구가 지난 10여년 이상 되어오고 있다. 가장 관심의 촛점이 되어 연구 되어온 것으로는 애착형성을 위해 중요하다고 하는 민감한 시기(Critical period)를 중심으로 애착의 특성인 시각, 청각, 촉각, 상호호혜적 관계, 긍정적 애정을 바탕으로 연구되어졌다. 이 연구는 부아 애착(Paternal Infant Attachment)의 연구를 연구방법, 측정도구 및 방법상문제와 변수들을 중심으로 재정리하여, 이 분야에 있어서 앞으로의 연구 방향을 살펴보았다. 17편의 연구들을 각각 년도, 표본수, 방법 및 측정, 결과 및 비고난을 비교 분석하여 도표를 작성하였다. 이론적 기틀과 문헌고찰에 근거하여 다음과 같은 적용과 제언을 한다. 1. 출산전 아버지의 특성에 대한 사정이 필요하다. 2. 연구자가 집단간 비교를 용이하게 하기 위해 연구전에 표본의 특성을 정확히 기술해야 한다. 3. 부모와 아버지의 과거력에 대한 상세한 정보수집이 강조되어야 한다. 4. 앞으로의 연구는 이론적 모델에 근거하여 이루어져, 대중교육 뿐 아니라 정책 결정에 기여해야 한다. 5. 연구결과 평가와 해석을 위해 정확한 이론적 근거가 필요로 된다. 6. 간호연구는 부적절한 부아 애착 형성에 있어서 아버지의 특성을 확인하고 부아유대와 애착 증진의 요소를 파악해야한다. 7. 부아 유대에 대한 위협요소 확인을 위한 도구개발과 그들에 대한 효과적인 간호전략이 필요 된다. 8. 가족에 있어서 모든 부모행위가 하나의 독립변수로서 연구되어야 하고 부아유대 증진에 관한 연구가 시도되어야겠다. 오늘날 부모들은 임신기간동안 많은 정보에 접하기를 원한다. 산전, 산후의 교육과 지식은 긍정적인 부아 관계를 증진시키고, 이것은 아동의 발달에 크게 기여할 수 있다. 긍정적으로 이러한 관계는 가족단위를 강하게 통합시키게 되므로 건강관리자(Health care workers)들은 애착에 대해 높은 관심을 갖어야 하겠다.

An underwater robot S/W framework consists of various sub-modules such as sensory data processing module, thruster control module, cognition module and behavior control module. Performance of a robot is determined by not only the efficiency of algorithms used but also effectiveness of their implementations. One most important factor of the effective implementation is the efficiency of data sharing module, as it transmits signals and data between the sub-modules and thus is directly related to the cycles of sensing and control The ideal data sharing module enables immediate access to any data source irrespective of system configurations. In reality, however, there are lots of obstacles including limitation of processing capacity of source modules, delay over network, and scheduling latency of operating systems. The paper proposes a new data sharing architecture and programming models to effectively handle such obstacles in implementation of underwater S/W framework on a small scale distributed computing system.

The purpose of this study is to analyse the reality and dynamics of transition of work-family reconciliation policy and gender regime in Germany to focus on recent introduction of parents benefit by applying meta path analysis. There is made of 'layering' in work-family reconciliation policy area. Because political barrier has alleviated they can introduce parents benefit, but cannot help stick to child care benefit because of internal barrier. But because parents benefit has activated by 'differential growth', German gender regime has suffered core transition of complementation that dominant structure has changed from 'sequential reconciliation' to 'concomitant reconciliation'. On the other hand, by 'purposeful decoupling' of gender area, core activists have attempted to cut the possibility of weakening of coordination relationship on main institutional areas of German model.

Software requirement analysis is necessary for successful software development project. Specially, incomplete requirement is the most influential causes of software project failure. Incomplete requirement can bring late delay and over budget because of the misunderstanding and ambiguous criteria for project validation. Software requirement patterns can help writing more complete requirement. These can be a reference model and standards when author writing or validating software requirement. Furthermore, when a novice writes the software scenario, the requirement patterns can be one of the guideline. In this paper proposes an automatic approach to identifying software scenario patterns from various software scenarios. In this paper, we gathered 83 scenarios from eight industrial systems, and show how to extract 54 scenario patterns and how to find omitted action of the scenario using extracted patterns for the feasibility of the approach.

As UCI (Universal Content Identifier) identification system becomes a national standard for content distribution, many digital contents are distributed through UCI identification system. However, problems associated with copyright infringement and copyright contracts occur due to lack of copyright information. ICN (Integrated Copyright Number), a code system developed for copyright management, includes copyright-related information for the purposes of usage settlement and accounting, illegal usage monitoring, and content filtering. ICN, however, has no information about distribution and content properties. Therefore, the linkage and integration between UCI and ICN can be a basis for the transparent and effective distribution of digital contents. In this paper, we propose a model for linking and integrating UCI and ICN, developing the efficiency in the value chain of each identified system by analyzing political factors and key technical elements between the two identification systems.

By conceptualizing UCC users' active behavior, this study newly presents two key concepts, 'self-expression' and 'artistic activity' of UCC users. Then, this study suggests a research framework to analyze text, image, and video UCC adoption processes by integrating those concepts with already-built UCC research tradition. Using the framework, we found that individuals who has a hard time expressing themselves in reality are likely to have a favorable attitude toward UCC, and the stronger the faith about the justice of self-expression and its freedom, the more the favorable attitude toward UCC. Furthermore, we confirmed that individuals who are very interested in artistic activity, and individuals who has high self-efficacy to their artistic talent are likely to participates more in UCC production. The role of other factors such as perceived enjoyment, the perception of critical mass of UCC adoption, and subjective norm also were discussed with limitations of this study.
