학생들의 기초 기본학습 능력의 신장이 강조되고 있는 교육상황에 비추어 볼 때 지금까지 간과되어 왔던 학습장애에 대한 재인식과 학습장애아들을 위한 대책이 필요하다. 그 대책으로 최근 특수교육분야에서 기존의 지능-불일치 교육이론에 대한 대안으로 제시되고 있는 중재-반응 (Responsiveness to Intervention : RTI) 이론을 기반으로 학습장애아들에 대한 교육이 보다 효율적으로 적용될 수 있다. 하지만 실제 우리의 교육에 적용을 위해서는 많은 걸림돌들이 존재하고 있다. 실제 교육 현장의 교사들이 RTI 이론 적용의 걸림돌로 제기하는 점들을 해결하기 위한 대안으로 모바일 시스템설계를 통해 실제 현장에서의 RTI 이론 적용 및 실행 가능성을 높이고자 한다. 본 시스템의 특징은 첫째, 실제 국내의 교육현장에서 기존 교사들이 제시한 RTI 이론 적용가능성이 낮은 항목들을 중점으로, 이론 적용의 문제점을 해결하기 위한 설계에 중점을 두고 있다. 둘째, 시스템의 구성을 기존의 행정중심이 아닌 실제 수행자 중심 설계를 위하여 기존의 학교행정가를 제외한 일반교사, 특수교사, 학부모, 학습장애 학생으로 설계하였다. 셋째, 일반교사, 특수교사, 학부모, 학습장애 학생의 의사소통 및 진전도 체크 등을 모바일 기기의 편이성과 결합하여 학습장애아의 학습능력을 향상시키고자 한다.

The year 1997 was when Korean Journal of Public Relations Research started to publish research articles. This study addresses the issue of theories in Korean public relations research. A total of 166 research papers are analyzed to see characteristics and changes during 2003-2012. Through this meta analysis, the researcher tries to see the big picture and discusses the right direction for the future of the public relations in many ways. Three different groupings were adopted to classify theories in the 10 year perion - 1. origins of theories(public relations field, related neighbor field, distant field), 2. target of analysis(individual, organization, society), 3. level of approach (systematic pluralistic, rhetorical, critical approach). According to the findings, though getting better, it was 'cold season' in public relations research because theories utilized in Korean public relations research were not very excellent qualitatively and qualitatively. Interdisciplinary approach is discussed.

Self-theories regarding general intelligence and English ability were measured from two countries (Korea and Pakistan) and their relationships with self-reported overall academic achievement and English language achievement were examined. No significant mean differences between the two countries were found regarding college students' self-theories. There were significant mean differences in overall academic achievement and English achievement between the two countries. Both the overall academic achievement and English achievement were significantly correlated with various self-theories while taking both samples together. Achievement measures were predicted by self-theories of general intelligence and English language ability. The current study highlighted the relationship between self-theories about general intelligence and English language ability and their relationship with self-reported achievement in two cultural contexts. This research also introduced new instruments to measure self-theories that can be used in studying self-theories in different domains.

Based on the strategic contingency theory, this study empirically examines Korean TV drama producers' changing adaptive behaviors in terms of genre variety given different levels of environmental uncertainty. The extant literature has suggested that firms tend to increase product variety in order to cope with increasing environmental uncertainty. This study attempted to verify the hypothesis that TV drama producers would employ wider variety of genre in the period with more uncertain environment(2003-2009) than the period with stable environment(1994-2002). Empirical results support the hypothesis, implying that TV drama producers tend to repeatedly produce dramas with the same genre in order to pursue efficiency in stable environment whereas they tend to employ a variety of different genre in order to cope with increasing environmental uncertainty.

Since emergency response training for maritime safety and safety education of maritime education institutions are conducted based on the set scenarios and education contents, there are limitations in the reduction of human error and response to various situations. Although there is a need for improvement, there is no way to improve response capabilities by assessing existing education training and securing diversity in situations. This study proposes a theoretical procedure analyzer method to model the diversity of situations for the improvement of emergency response training. This paper defines the human and system theoretical procedure analysis model (HSTPA) based on the organic relationship of the source and system. The limitations of the existing training were derived by analyzing the errors that each component could produce and applying them to the fire response training scenarios requiring vertical reporting systems and responses. The segmentation and inspection of training scenario considerations applying the proposed HSTPA model is believed to help create diverse and realistic scenarios in emergency response training and education, and improve the situation judgment understanding and response capabilities of the subjects.

This paper presents an analysis of the instability phenomenon on motorways, with the aim of arriving at the definition of a control strategy suitable for keeping the flow stable. By using some results of the motorway reliability theory, a relationship and some flow characteristics is obtained, which shows that the existence of a reliability threshold critical for flow stability. The macroscopic flow characteristics corresponding to this threshold are very different in different situations, so that this control of flow stability requires the analysis of speed and density microscopic process surveyed on a cross section of the motorway carriage ways to be controlled. A method is presented, based on integrated moving average(IMA) analysis in real time of these processes, by which it is possible to detect the approach of instability before its effects become manifest, and to single out the proper control strategy in different situations.

As the distribution rate of a smart phone which can actualize even augmented reality is getting higher, the application scope of a smart phone is sharply increasing. However, in spite of various functions of it, there is still lack of learning app. Mobile equipments can bring no spatial-temporal restriction of learning to a learner, but they can tempt a learner into inappropriate spaces. In this sense, learning app is necessarily needed to motivate and keep learner's inner desire. This thesis suggested considerations when learning mobile app is designed by analyzing motivation strategy of ARCS Theory and UI of web based contents. Also, a design method of mobile learning app was suggested based on a procedural model of mobile learning app adapting ARCS Theory.

As the characteristics, attributes, and accepted way of media have been changing with newly emerging media, human recognition and the communication structure have also been changing. Media are not isolated from the others and emerge in the cultural context; With the drive to juxtapose the old and the new to be in diversified forms, the old media are utilized and improved. In this rapidly changing circumstance by the media, we attempt to theoretically explore the concept and characteristics of visual communication and the media related to augmented reality. Augmented reality does not create something out of nothing but renew the expression; Thus, it reforms the structure of communication. Therefore, there is a significance to look into theories of W.Benjamin, M.McLuhan, Norbert Bolz, and Jean Baudrillard who linked the past to the present in accordance with the new era of communication for us to find out the meaning of augmented reality in the current cultural context.

상수도 관망의 운영 단계에서 비정상상황의 발생은 필연적으로 발생하며, 비정상상황 발생 시상수도 관망 내 설치된 제수 밸브의 차폐를 통해 해당 구역의 격리 후 복구를 진행한다. 일반적으로 제수밸브를 통해 격리될 수 있는 최소 구역은 세그먼트로 정의하고, 제수밸브 설치 시 세그먼트의 격리로 인한 상수도 관망의 피해를 줄일 수 있도록 위치를 선정한다. 제수 밸브를 통한 격리 시 상수도 관망의 흐름 경로와 유향, 유속의 변화와 같은 수리적 특성 변화가 불가피하다. 지난 '19년도에 발생했던 3건의 수질 사고가 수리적 특성 변화에서 기인했던 것을 고려할 때, 제수밸브 차폐로 상수도 관망의 부분 격리 시 발생 가능한 수리적 특성 변화에서도 수질 사고가 야기될 가능성이 있다. 기존 제수밸브 위치를 결정한 연구들을 보면, 대부분 제수밸브 위치에 따라 결정된 세그먼트의 격리 시 수압 저감을 고려하여, 격리 시에도 상수도 관망의 성능을 최대한 유지할 수 있도록 결정하는 것이 일반적이다. 다만, 앞서 언급한 것과 같이 격리 시 발생 가능한 수리적 특성 변화로, 수압 저감 외에도 예기치 못한 수질 사고의 발생 원인이 되기도 한다. 이에 따라 제수밸브의 최적위치를 결정할 때 수리적 특성 변화를 고려해야 예지치 못한 2차 피해를 줄일 수 있을 것이다. 이에 본 연구는 그래프이론을 활용하여 격리 전후 관로의 유향 변화를 최소화하도록 제수밸브 최적 위치 결정하는 방법론을 제안한다. 그래프이론은 망의 형태를 가지는 상수도 관망의 연결성을 정량화할 수 있으며, 본 연구에서는 수리학적 거리 인자를 적용하여 격리 시에도 각 수요절점이 최소 경로를 확보할 수 있도록 유도하였다. 해당 방법론은 가상 관망에 적용하여 수리학적 거리 인자에 따른 설계와 기존 상수도 관망 성능 극대화 설계 안을 비교하였다. 또한 수질 사고 위험도 인자를 정의하여 해당 인자에 따른 각 설계 안의 효과를 분석하였다. 본 연구는 향후 수질 사고를 고려한 밸브 시스템의 설계 및 운영에 활용할 수 있을 것으로 기대한다.
