The purpose of this paper is to research the effect of a reflection journal on self motivated-learners' study. The learners were divided into experimental and control groups, we carried out the pre- and post- surveys, and compared the groups' academic achievements. As a result, their persistent learning, self-efficacy, learning attitude somewhat improved and their academic achievement as well.

This paper presents a navigation error compensation scheme for Strap-Down Inertial Navigation System(SDINS) using electro-optical sensor. The proposed scheme uses the position or the attitude information from the sensor. For each case, Kalman filter model is derived and implemented. To show the effectiveness of the present compensation scheme, computer simulations have been carried out resulting in the boundedness of position and attitude errors.

Previous studies on user training have largely focused on assessing models which describe the determinants of information technology usage or examined the effects of training on user satisfaction, productivity, performance, and so on. Scant research efforts have been made, however, to examine those effects of training by using theoretical models. This study presented a conceptual model to predict intention to use information technology and conducted an experiment to understand how training for computer skill acquisition affects primary variables of the model. The data were obtained from 32 student subjects of an experimental group and 31 students of a control group, and the information technology employed for this study was a university's electronic mail system. The study results revealed that attitude toward usage and perceived behavioral control helped to predict user intentions; outcome expectations were positively related to attitude toward usage; and self - efficacy and perceived behavioral control. The changes in those variables suggest more causal effects of user training than other survey studies.

In this study, we developed a Hedonic Model for Retargeting Advertising Based on Consumer-centerd IoT space for offering useful, interest, and interactive information to consumer. And most existing relative researches about Internet of Things but, this paper focusing on the Type of information, humor, and interactive and analyze the attitude and clicks intention to Retargeting Advertising Based on Consumer-centerd Internet of Things. According to the results, humor Advertising is positively related to attitude and click intention toward Internet of Things Advertising. But information Ad and interactive Ad affect positive to click intention. This is mean that click intention is more immediate reaction of consumers in the IoT space. Therefore Future research will be designed in a more interactive elements that can lead to positive reaction of consumers on the Internet of Things be more effective if you advertise advertising.

In this paper, we implemented a flight posture simulator that intuitively understands aircraft flight posture and visualizes the principle of motion. The proposed system operates the 6 - axis motion platform according to the change of the navigation information and transmits the flight attitude to the simulator using the gyro sensor. A gyro sensor and an acceleration sensor are used together to analyze the attitude of the aircraft. The reason is that the gyro sensor has a cumulative error in the integration process. And the accelerometer sensor was compensated by using the complementary filter because noise was serious due to short term vibration. Using the compensated sensor information, the motion platform is operated by calculating the angle to be transmitted to the 6-axis motor. And visualization result is implemented using OpenGL. The results of this study can be used as teaching materials for students related to aviation in the future.

The study results revealed that attitude toward usage and perceived behavioral control helped to predict user intentions ;; outcome expectations were positively related to attitude toward usage ; and self-efficacy was positively related to perceived behavioral control. The hands-on training for the experimental group led to increases in perceived ease of use, self-efficacy and perceived behavioral control. The changes in those variables suggest more causal effects of user training than other survey studies.

유비쿼터스시대의 핵심기기로 중요성을 더해 가고 있는 이동전화와 무선인터넷기술의 발전은 현대 비즈니스 환경의 급격한 변화와 함께 광고활동에도 많은 변화와 새로운 기회를 제공하고 있다. 무궁이 변화하는 환경 속에서 소비자 행동을 새롭게 파악할 수 있는 플로우를 중심으로 살펴보았고, 이용자들의 광고 회피로 인해 광고 효율성이 점차 낮아지고 있는 현 시점에서 광고태도에 따른 회피 현상들을 통계프로그램 SPSS와 AMOS를 통해 분석하였다. 이에 따른 결과는 휴대폰 사용자의 플로우가 상태일 때 모바일 광고효과인 광고태도에 긍정적인 영향을 미치는 것으로 나타났고, 광고태도는 광고회피에 영향을 미친다는 연구 결과가 나왔다.

Empirical studies of superior's ethical leadership on organizational effectiveness of organization member have been done in various fields. However, it is difficult to find the previous research on civil servant in public sector. Therefore, the purpose of this study is to analyse causal relationship of ethical leadership and organizational effectiveness and to suggest theoretical and political implication for enhancing the level of civil servant's organizational citizenship behavior. As the result of analysing the causal relationship of superior's ethical leadership and organizational citizenship behavior, the factor of organizational effectiveness as the public attitude, this study shows that normative behavior, communication, reinforcement, and right decision-making have significant effect on organizational citizenship behavior. Based on these results, this study suggested theoretical and political implication and the limitations of study.

본 논문에서는 모바일 애플리케이션의 사용자 잔존율 향상을 위한 방안으로써 내러티브 모션을 기반한 온보딩을 제안한다. 모바일 기술의 발전과 새로운 미디어에 대응하는 디지털콘텐츠 애플리케이션에 대한 관심이 증가하고 있는 가운데 사용자에게 외면받아 사라지는 애플리케이션의 증가가 가속화되고 있다. 이에 따라 사용자의 긍정적 경험 제공을 위한 사용성 향상 연구는 빠르게 진행되고 있으나 애플리케이션의 첫인상과 지속적인 사용을 결정하는 온보딩에 대한 연구는 아직 미비하다. 경쟁이 가속화 될수록 보다 효과적인 사용자경험을 제공하기 위한 온보딩 개발의 중요성은 증대되어 갈 것이며, 결국 온보딩 개발의 핵심 쟁점은 사용자의 긍정적인 인지적 반응과 태도를 이끌어낼 수 있는 요인인 모션이 될 것으로 예측된다. 따라서 본 논문에서는 모바일 온보드에서 제공되는 애플리케이션의 다양한 특성을 표현하기 위한 요인으로서 내러티브 모션을 제시하고 애플리케이션 지속사용 여부에 영향을 미치는 요인을 도출하여 둘의 상관관계를 실증적으로 분석함으로써 앞으로 등장할 새로운 서비스 및 플랫폼의 애플리케이션 개발 필요한 모션요소를 도출하고자 한다.
