This study analyzes the latest statistics for 3 years based on the traits of market environment, internal organization characteristics(the size and distribution of workforce), and financial structure, and then, investigates the interactivity traits and drawbacks between organization and market environment, among the local broadcast stations, and, among the type of work in the internal organization, by interviewing with broadcasters working at the local stations. Major findings of this studies are : at first, statistically, the conditions of local market environment, the size of local station workforce, financial structure are very poor. And, the interactivity among the local broadcast stations have so many difficulties because of a conflict of interest. So, for getting over a difficult situation at the local stations, in addition to planning to support local stations with various policies, government and local stations should seek for solution to overcome the conflict of interest jointly.

웹 2.0을 적용한 블로그, 위젯, RSS 등의 여러 가지 기술들의 발전은 계속적으로 변화하는 교육에 필요한 다양한 툴을 제공해 주고 있다. 현재의 초등학교 교육은 단순히 지식을 전달하고 그것을 학습하는 과정뿐만 아니라 교수자와 학습자, 학습자와 학습자 사이의 상호작용을 통한 교수.학습과정이 이루어지고 있다. 따라서 앞으로의 교육은 교수자와 학습자 모두가 참여하는 형태로 발전하게 될 것임에 분명하다. 그러나 이러한 상호작용에만 국한될 경우 학습자들이 기본적으로 알아야 할 핵심지식에 대한 교육이 소홀해 질 수 있다. 따라서, 교수자와 학습자가 원활한 상호작용을 이루어 질 수 있는 새로운 형태의 학습 환경이 필요함과 동시에, 핵심지식의 전달이 원활하게 이루어질 수 있는 툴이 필요하다. 본 연구에서는 웹 2.0의 여러 가지 기술들을 통해 교수자와 학습자가 원활한 상호작용을 이룰 수 있는 환경에 대한 분석을 통하여 핵심지식의 전달이 원활하게 이루어질 수 있는 교육용 위젯을 개발하였다. 본 연구에서 개발한 교육용 위젯을 활용한다면 교수자와 학습자의 상호작용을 통한 교육에서 다루지 못하는 부분의 핵심지식 교육을 보충함으로써 학습자들의 핵심지식의 습득 및 학습효과를 증진시키는데 기여하게 될 것이다.

In this paper, we describe a new method for acquiring calibration data using a user interaction process, which occurs continuously during web browsing in gaze estimation, and for performing calibration naturally while estimating the user's gaze. The proposed non-intrusive calibration is a tuning process over the pre-trained gaze estimation model to adapt to a new user using the obtained data. To achieve this, a generalized CNN model for estimating gaze is trained, then the non-intrusive calibration is employed to adapt quickly to new users through online learning. In experiments, the gaze estimation model is calibrated with a combination of various user interactions to compare the performance, and improved accuracy is achieved compared to existing methods.

Many science education research and practices are recently emphasizing the importance of collaborative learning. This study also understands learning in aspects of socio-cultural context, and regarded the creation of meaning in a same-age group as an important learning process. This is most especially true in the premise that the formation of roles in a collaborative learning is important for successful interactive learning. This study aims to find out how roles form in a group. For this purpose, university students participating in a group discussion activity about energy flow and circulation of material were selected as research participants. Discussions among the nine students in one group consisted of cognitive conversations on the topic and operational conversations for preparing a presentation. Video-clips of the discussions were made and transcribed. For the analysis, we developed a framework that includes four interaction functions (cognitive, organizational, meta-cognitive, operational), four action elements (question, simple answer, providing opinion, response to opinion), and two to four intention elements by each action elements. As a result, a total of nine roles were revealed through the interaction function and element; cognitive questioner, operational questioner, simple answerer, operational suggester, organizational commander, operational commander, cognitive explainer, terminator, reflective thinker. These roles are re-classified into seven utterance patterns by the utterance order and object, and they were categorized into three role groups (facilitating interaction, sustaining interaction, finishing interaction). The result means that role formation and function can have influence on learning and interaction. This study is meaningful to the suggestion to collaborative learning including project-based learning, investigation, club activity, and for the re-illumination of the role in an aspect of the interaction.

과학적인 유역관리를 위한 모형개발 환경의 구현은 구체적인 방법론의 제시와 더불어 중요한 연구과제이다. 모형개발자들은 개발과정이나 표현과정, 모형의 보정 혹은 구동과정에서 빈번히 반복적이고 시간 소모적인 소프트웨어의 작업을 수행해왔다. 이 과정에서 상당한 시간과 자원의 낭비가 발생되었고, 많은 경우 개발된 모형이 일반화되는데 상당한 장애요인이 되었다. 또한 개발자들 상호간의 상이한 개발환경은 모형의 통합이나 상호검증에 긍정적으로 작용하지 못했다.(중략)

On top of presenting the possibility of expanding the game space to social space through mobile communication, MSNG reinforces the strengths of SNS and the fun of games through closer networks between users. This study empirically verified the effects of the characteristics of MSNG on interactions and user satisfaction by dividing the main characteristics of MSNG into graphics, challenge spirit, and reward, and then dividing the main characteristics of mobile social network service into social interaction and technical interaction. In the results of study, the main characteristics of MSNG such as graphics, challenge spirit, and reward all had significant effects on the social interaction and technical interaction while the social interaction and technical interaction of MSNG also had significant effects on the user satisfaction, so that the hypotheses of this study were all selected. The influence of the characteristics of MSNG on interactions might be because of shared feedbacks through graphics, game tasks, and reward in the performance process of MSNG, and such interactions make diverse people have the horizontal or circular communication, which is led to the increase of user satisfaction.

주어진 계획 문제로부터 휴리스틱을 이용하여 최적의 해 계획을 구하기 위해서는 허용 가능한 휴리스틱을 이용하여야 한다. 이러한 허용 가능한 휴리스틱은 실제 목표 도달거리보다 짧거나 같아야 하는데 휴리스틱 평가치가 실제 목표 도달거리에 가까울수록 계획생성을 위한 탐색 효율성이 높아진다. 하지만, 이러한 허용 가능한 휴리스틱 평가치를 구하는 과정은 매우 복잡하며 계산량이 많기 때문에 실제 계획 생성 과정에서 사용하기는 어렵다. 때문에 최대 휴리스틱과 같은 허용성을 만족하는 간단한 휴리스틱을 이용하고 있으며, 이로 인해 최적의 계획 결과를 얻을 수는 있지만, 탐색의 효율성이 떨어지는 결과를 가져오고 있다. 본 논문에서는 이러한 문제를 해결하기 위해서 기존의 계획그래프를 개선한 새로운 계획그래프인 확장된 계획그래프(EPG)를 이용한 MAX+ 휴리스틱 계산법을 소개한다. 확장된 계획그래프는 계획 문제 풀이를 위한 휴리스틱 계산에 이용되는 기존의 간략화된 계획그래프를 목표조건들 간의 상호작용을 확인 할 수 있도록 확장한 자료구조로써 목표조건들 간의 긍정적/부정적 상호작용을 찾는다. 이를 위해서 모든 목표조건들이 등장할 때까지 그래프를 전개하는 기본 전개 과정과 함께, 이 과정에서 발견된 동작과 목표 조건들과의 관계를 바탕으로 한 추가 전개 과정으로 이루어져 있다. 그리고 이 과정을 통해서 목표조건들간의 상호작용과 최단 거리를 구하게 된다. MAX+ 휴리스틱 계산에서는 이러한 목표조건들 간의 긍정적/부정적 상호작용의 존재 유무를 찾아내게 됨으로써 전체 목표 집합에 대한 보다 정확한 최소 도달거리에 대한 평가치를 찾게 된다. 따라서 MAX+ 휴리스틱은 기존의 최대 휴리스틱 보다 더 정보력 높은 휴리스틱을 구할 수 있는 장점이 있다. 본 논문에서는 MAX+ 휴리스틱의 계산 과정과 MAX+ 휴리스틱의 정확성과 이를 바탕으로 한 탐색 효율성을 확인하기 위한 실험적 분석에 대해 설명한다.

As various genome projects have produced enormous amount of biosequence data, functional sequence analysis in terms of tile nucleic acid and protein becomes very significant. In functional genomics and proteomics, the functional analysis of each individual gene and protein remains a big challenge. Contrary to traditional studies, which regard proteins as not components of a whole protein interaction network but individual entities, recent studies have focused on examining functions and roles of each individual gene and protein in view of a whole life system. In this regard, it has been recognized as an appropriate method to analyze protein function on the basis of synthetic information of its interaction and domain modularity. In this context, this paper introduces the PIVS (Protein-protein interaction Inference & Visualization System), which predicts the interaction relationship of input proteins by taking advantage of information on homology degree, domain modules which input sequences contain, and protein interaction relationship. The information on domain modules can increase the accuracy of the function and interaction relationship analysis in terms of the specificity and sensitivity.
