카플란과 노턴에 의해 1992년에 처음 소개된 BSC (Balanced Scorecard)의 '재무', '고객', '내부프로세스' 그리고 '학습과 성장'의 4개 시각 중 '학습과 성장' 시각의 핵심성과지표를 도출하는 것이 본 연구의 목적이다. 기존 연구에서 제시된 평가 지표의 한계점을 제시하고 성과지표 도출의 근원을 조직 행동론에서 제시하고 있는 성과개념과 과정이론에서 밝혀냄으로서 '학습과 성장'시각의 목표인 다른 세 시각의 하부구조 및 동인을 달성하고자 조직 행동이론 관점의 핵심성과지표를 제시하고자 한다. 또한 정보기술이 기업의 장기적인 역랑을 배가시키고 경쟁우위를 확보하기 위한 전략적 수단으로 인식됨에 따라 정보기술의 역할 및 효과성에 대한 측정과 평가가 중요한 이슈로 떠오르고 있기 때문에 '학습과 성장' 시각에서 인적자원의 역랑과의 균형있는 정보기술 역량을 측정하고 평가할 수 있는 지표를 제시하고자 한다. 이는 기업 경영활동의 근간이 되는 구성원과 단위조직, 그리고 정보기술이 기업성과데 미치는 영향을 정확히 파악하고 그 결과를 구성원과 조직의 보상체계로 연결시킬 수 있는 객관적인 잣대로서 작용하게 된다.

멀티스레드 프로그램의 효과적인 디버깅을 위해서는 스레드의 비결정성에 의해 야기되는 다양한 수행 양상의 직관적인 이해가 중요하다. 스레드 수행 양상을 시각화하는 기존의 기법들은 공유 변수의 접근사건들 간의 부분 순서를 표현함으로써 시각적 복잡도가 높거나 이전 수행에서 결정된 락킹 순서를 표현하여 잠재되어 있는 다른 수행 양상에 대한 정보를 제공하지 못 한다. 본 논문은 프로그램 수행의 비결정적인 부분 순서는 락의 종류와 속성을 포함하는 코드 블록으로 시각화하고, 결정적인 부분 순서는 블록들을 연결하는 간선으로 시각화한다. 본 연구의 그래프는 플랫폼에 독립적인 Java Swing으로 구현하고 합성 프로그램을 사용하여 효과성을 실험한다.

기존 시각언어 컴파일러 자동화 도구는 시각 구문의 그래픽 정의부분을 명세하고 확장 및 수정하는 방법의 한계로 인해 어휘분석단계를 처리하는데 어려움이 있다. 이러한 문제점을 해결하기 위해 본 논문에서는 객체지향 시각언어 문법을 기반으로 한 새로운 방식의 문법 기반 자동 생성 시스템인 시각언어 컴파일러 자동 생성 환경(CGE-VL)을 구축한다. 이 시스템은 객체지향 패러다임을 기초로 한 시각언어 컴파일러 구축을 위한 실질적인 도구로 기존의 시각언어 컴파일러 자동화 도구와는 구별되는 객체지향 시각언어의 효과적인 명세 방법 제공, 어휘분석기를 이용한 파싱 시간의 단축, 객체지향 파서를 자동 생성하는 등의 새로운 특성을 제공한다. 이러한 특성은 특히 동일한 의미를 가지는 언어 구성요소가 그 쓰임에 따라 서로 다른 구체화된 의미 및 행동을 가지는 객체지향 시각언어에서는 언어 명세에서 최종 산물인 컴파일러에 이르는 전 단계에 동일한 객체 지향 패러다임을 사용함으로써 일관된 개발방법을 제공하여 그 효과가 두드러진다.

This paper proposes a computational model which can simulate peculiar language phenomena observed in human lexical decision task. The model is designed to mimic major language phenomena such as frequency effect, lexical status effect, word similarity, and semantic priming effect. The experimental results show that the propose model replicated the major language phenomena and performed similar performance with that of human in LDT.

In this paper, affection of jumping motion factors on visual effects are studied for game character's natural motion realization. First, 3 kinds of games that realize natural motions are selected and 4-types of characters jumping motions are captured from it. Then, the motions are measured using four fundamental principles of jumping as takeoff strength, landing impact, landing elasticity and flexibility, and measured in motion factors as time, distance, angle either. Finally, consistent characteristics of visual effects and motion factors on jumping motion are suggested. The study could be used to basic information for realization of character's natural jumping motion.

The purpose of this study was to explore the effects of a visual-analogical learning model based on theoretical research on visual thinking and analogical learning. To examine the effect of visual-analogical learning, both an experimental group and a control group were selected from 6th graders at H elementary school in Yeonsugu, Incheon and tested on creativity and science achievement Results of this study showed as that visual-analogical learning produced statistically significant differences for changes in student creativity, For the individual components of creativity; openness, fluency, and originality, results showed greater increases for the experimental group, whereas flexibility showed only statistically significant differences. In regards to science achievement, the experimental group showed a bigger increase than the control group, but these findings were statistically nonsignificant For changes to creativity in the group divided according to creativity score, this instructional method was more effective in the middle and lower group than the higher group, An investigation of attitude, revealed a positive student reaction students felt these science classes to be more interesting than previous science classes. Moreover, students wanted to create new innovative product themselves.

In this study, an unplugged education method which focuses on the data visualization training was applied to third grade students of an elementary school and analyzed its impact on enhancing their computational thinking. The analysis was conducted on 60 elementary school teachers and 124 third grade students and the unplugged education program based on the data visualization procedure was developed. The education program developed was carried out with 24 third grade students for 36 hours over six days. The effect of the program applied was analyzed through the pre-to-post comparison performed with perceptive strength test and creativity test in order to examine the enhancement in computational thinking. According to the analysis result, the unplugged education method which focuses on the data visualization training has significant effect on the 'computational perception' and 'creativity' of third grade students.

The purpose of this study is to produce visual content for effective education of Passive verbs and Causative verbs in Korean language education for foreigners. Passive verbs and causative verbs are contents that must be taught to intermediate level learners. However, it is recognized as a difficult item for both learners and Korean teachers because the realization pattern is complicated, and there is no rule to explain the combination relationship between the action and the instruction by suffix. In this article, the use of nonverbal information that can improve the learning effect was considered. Providing verbal and non-verbal information together in language education can be expected to improve learners' communication skills. In particular, visual content is non-verbal information that can positively affect memory enhancement, playback, and transition. Therefore, this study attempted to plan and produce picture cards as visual materials. The picture card, produced with a focus on the correct education of Korean Passive verbs, will efficiently and significantly make Korean Passive verbs and Causative verbs teaching and learning by suffixes.

This study deals with the visual quality in the future urban landscape and architectural environment, and as such, aims to identify a scientific and objective aesthetic and visual quality from the perspective of empirical aesthetics. The empirical aesthetics provides a framework that can be utilized in understanding human perception, consciousness, and behavior and a way to categorize the visual quality and to explain and predict its effect. The study examines various theories on environmental perception, cognition, and some new approaches to environmental aesthetics, and tries to present aesthetic properties that can be applied to environmental design. First, the aesthetic experience in visual perception can be defined as a combined effect of psychobiological properties and human activity, i.e. an interaction between the formal and symbolic signs in environment and the conceptual framework of man. The effect of visual quality differs and varies a great deal, depending on the sociocultural, personal and collective value system, so it is hard to define it in absolute terms. Second, the impact of visual quality and its aesthetic effect has to do with pleasure, preference, the aptitude for survival, and self regulation. Third, aesthetics is one of the areas that can benefit a great deal from an interdisciplinary approach. and an empirical study such as this can be used as a basis for design, planning, and evaluation.
