  • 최근 국가적 차원에서 영어교육에 대한 많은 투자가 이루어지고 있으나 기존의 주입식, 암기식 영어 교육은 회화 실력 향상에 큰 도움을 주지 못하였다. 컴퓨터를 이용한 영어교육 또한 많은 관심을 얻고 있으나 실제 의사소통을 위한 회화 학습에 대한 고려는 깊지 않으며, 주어진 흐름의 대본을 따라 단순히 읽고 반복하는 수준의 시스템만 존재하고 있다. 이러한 학습형태는 흥미 유발 동기가 약하여 사용자로 하여금 장기간 꾸준히 학습하게 만들지 못한다는 문제가 있다. 이러한 문제점에 대하여 제2언어 습득 이론에 바탕을 둔 자연어 처리 기반 몰입 환경 영어 교육 시스템을 제안한다. 이는 도메인 확장성이 뛰어난 예제 기반 대화 시스템을 3 차원 가상공간과 결합한 시스템으로 자연스러운 대화를 통한 외국어 회화 연습을 하는 과정에서 학습자의 발화 오류를 분석하고 교육적 피드백을 제공한다. 또한 현실과 비슷한 몰입 환경에서 체험형 기술을 통해 자발적인 학습을 유도하고 집중력, 기억력을 획기적으로 높이고자 한다. 본 논문에서는 영어교육 시스템의 이론적 배경, 예제 기반 대화관리, 시스템 구성요소와 동작에 대하여 중점적으로 기술하였다.

  • The purpose of this study is to review Saeromaji Plan 2015 (the Second Basic Plan for the Low Fertility and Aging Society) with the framework of WHO's (2007) guidelines for building age-friendly cities and to provide suggestions for improvements in planning for the aging society. The contents of the Plan pertaining to the aging society sections were reviewed by two independent researchers to examine the extent to which the Plan fulfilled 169 checklists across 8 themes proposed by WHO. The results indicate that all 8 themes were partially reflected in the Plan. Suggested improvements for planning for the aging society include taking an inclusive approach to bring generations together, providing more options for older adults, and including more active involvement of the private sector in planning.

  • In 1995 of May, the Ministry of Construction and Transportation (NOCT) developed the First Nation-wide Master Plan of GIS. It is set up in response to an increasing and various demands on spatial informations. Until now, a set of diverse projects related to spatial information have been proposed and executed. However, cost-benefit analysis of investment and decision making for alternatives have not been carried out appropriately because scientific evaluations for obtaining efficiency and economical validity of investment have been deficient. Optimum decision making for projects based on itemized priority order using effect or cost of proposed alternative plan is a fundamental expedient for demonstration of propriety of projects and enhancement of efficiency of investment. From such understanding, this paper applied the analytic hierarchy process (AHP) technique to the cost required to construct a GIS so that analyze the weight of each cost factor.

  • Dangsan forests had been established by local residents several hundred years ago. They were disturbed in various ways, but still remain in many villages where dangsan festivals are held every year. Although the remaining Dangsan forests represent korean rural cultural landscapes, their characteristics still remain to be uncovered. The objectives of this study were to understand the three elements, Dangsan tree (Divine tree), shrine and stone tower, and to investigate the culture at inland areas and seashore areas relation to Dangsan forests. Twenty cases of Dangsan forests at inland areas and twenty at seashore areas were investigated. There were nine shrines and six stone towers found out of twenty inland Dangsan forests. Fifteen shrines were found out of twenty seashore Dangsan forests. Stone tower was not found at seashore areas. Fifteen events of dangsan festival were investigated. Dangsan festival appeared to have played an important role to preserve Dangsan forests. Based on the findings of this study, Dangsan forests are, as landscape elements at inland and seashore areas, proved to have a potential for the improvement of cultural and natural landscapes in the country.

  • The emerging technologies for the natural computer interaction can give manufacturers new opportunities of product innovation. This paper is the study on a method of human communication about a finger gestures interaction. As technological advance has been so rapid over the last few decades, the utilizing products or services will be soon popular. The purpose of this experiment are as follows; What is the usefulness of gesture interaction? What is the cognitive impact on gesture interaction users. The finger gestures interaction consist of poking, picking and grasping. By measuring each usability in 2D and 3D space, this study shows the effect of finger gestures interaction. The 2D and 3D experimental tool is developed by using LeapMotion technology. As a results, the experiments involved 48 subjects shows that there is no difference in usability between the gestures in 2D space but in 3D space, the meaningful difference has been found. In addition, all gestures express good usability in 2D space rather than 3D space. Especially, there are the attractive interest that using uni-finger is better than multi-fingers.

  • 모바일 및 무선 플랫폼등의 소형 정보기기의 사용에 있어 제기되는 가장 큰 문제점은 디스플레이 공간과 입력장치의 제약이며 소형 디스플레이 정보기기에서 정보검색의 효율성과 제 검색에 있어 여러가지 문제점을 야기시킨다. 이러한 문제의 해결을 위해 많은 연구가 진행되고 있는데 이중 정보시각화 기법은 데이터간의 관계가 명확하여 특정분야의 정보를 찾아내고 분석 하는데 효율적이다. 본 연구에서는 소형 디스플레이 정보기기 중 PMP (Portable Multimedia Player)에서 음악 화일 검색을 위한 정보 검색 방식을 3차원 정보시각화 기법을 활용하여 소형 디스플레이에서의 사용성의 한계를 해결하고자 하였다. 이러한 목적으로 디자인된 Navigation System은 기존 제품에서 선행된 검색방법보다 빠르고 다양한 검색과 사용자로 하여금 조작에 있어 몰입할 수 있는 감성적 만족을 제공할 수 있다. 또한, PMP뿐 아니라 소형 디스플레이를 가진 다양한 미디어에 적용 가능할 것으로 본다.

  • This paper proposes an error model with integral action and a pole-place-ment self-tuning controller for robot manipulators in task coordinates. The controller can reject the offset due to any load disturbance without a detailed description of the robot dynamics. The error model parameters are estimated by the recursive least square identification algorithms, and controller parameters are determined by the pole-placement method. A computer simulation study has been conducted to demonstrate the performance of the proposed control system in task coordinates for a 3-joint and 2-link spatial robot manipulator with payload.

  • For the information on micellization at each ginsenoside level aqueous solution of purified saponin of Panax ginseng root was dialyzed through dialysis tubing (MW 12,000) or eluted through Bio-Gel P-2 (MW 200-2,000) and analysed for ginsenosides by high performance liquid chromatography. Ginsenosides can be classified into three groups depending upon molecular aggregation pattern and spatial arrangement of hydrophilic parts in molecule. Group I that is large micelle former(aggregation number: above 10) and one side hydrophilic part (HP) includes $ginsenoside\;Rb_1$, $Rb_2$, Rc and Rd (diols). Group II thai is small micelle former (aggregation number:>10-1) and semi-two sales HP includes $Rg_2$, Rf (triol) and $Rg_3$ (diol). Group III that is no micelle former (aggregation number: 1) and two sides HP includes Re and $Rg_1$ (triol).
