통계청과 보건복지가족부에 따르면 우리나라는 65세 이상 고령인구 비율이 세계 평균치보다 높게 추정되며 이미'고령화 사회(Ageing Society)'에 접어든 것으로 나타났다. 또한, 예상보다 이른 시기에 정보사회에 도달하여 국민들의 삶의 질이 개선되었을 것으로 추정된다. 그러나 고령층은 젊은 층과 달리 새로운 기계에 선뜻 접근하기 어려워 정보의 접근 및 이용에 있어 뚜렷한 차이를 보이고 있어 세대 간 정보 격차(Digital Divide) 현상을 야기 시키고 있다. 이러한 현상을 해결하기 위해 고령층을 위한 음성인식 기반의 스마트 미러 시스템을 구현하였다. 구현한 시스템은 음성인식을 통하여 조명제어 및 날씨, 지하철 시간 정보 조회 서비스를 제공할 수 있다. 구현한 시스템을 통하여 고령층에게 새로운 기계에 대한 접근 용이성을 제공하여 새로운 시대 변화에 동참하는 느낌을 주고 정보를 얻어 생활이 편리하게 만들어 준다는 효과가 기대된다.

The parallel-type mechanism provides more accurate and stiff motion than the serial-type mechanism. However, in case of using the haptic device, the performance of the force reflection can be deteriorated due to the singular points existing in workspace. In this paper, we propose a redundantly actuated parallel 3-DOF haptic device, which is singularity-free in the workspace and has an improved force reflection capability. In addition, we propose a new force distribution algorithm, which can reflect force of both high and low resolution, using two sets of actuator with different size. Redundant actuators are attached to the base frame in order to minimize the inertia of the system. Moreover, a wire and gear reduction system is employed to achieve high force reflection along with soft feeling. We confirm the performance of the force reflection capability throughout simulation.

Visual art elements can most intuitively express the information expressed by a game character and play an important role in shaping a successful game character. We compares and analyzes the role design in the skins of the "Five Tiger-like Generals" series in Glory of Kings in terms of color, line, graphic and other visual elements. Different visual elements form different visual impacts and influences, which brings people different psychological feelings and presents different emotional colors. The reasonable use of visual elements gives people a refined visual experience and a comfortable psychological feeling, adding more influencing factors to the "immersion" of the game. It not only can strongly attract the attention and love of players, but also spreads traditional culture of the nation and the country. Therefore, whether the visual art elements of a game character can be appropriately used is an important part of the success of the game work. The analysis of visual art elements of game characters has important learning and research value.

Three-dimensional(3-D) sound is a technique for generating or recreating sounds so they are perceived as emanating from locations in a three-dimensional space. Three dimensional sound has the potential of increasing the feeling of realism in music or movie soundtracks. Three-dimensional sound effects depend on psychoacoustic spectral and phase cues being presented in a reproduced signal. In this paper we propose an effective algorithm for the sound image expansion in television system using stereo image enhancement techniques. Compared to the other techniques of three-dimensional sound, the proposed algorithm use only two speakers to enhance the sound image expansion, while maintaining the original sound characteristics.

The purpose of this study was to classify the cognitive management style of housewives, to explore the effect of demographic variables on the style, and to investigate satisfaction of resources such as money, time and energy, according to different styles. For this purpose, the samples of 355 housewives were collected in Seoul. And various analysis methods, such as frequencies, percentages, means, chi-square test and GLM, were employed. The results of this study were as follows ; 1) Among 355 respondents, systematic managers, analyzing managers, holistic managers and feeling managers were 103, 96, 82 and 74 respectively. 2) Depending on information gathering and evaluation, the style was influenced by wives' education, wives' employment status, and family life cycle. 3) By style, satisfaction of resource was differenciated significantly. Between money, time and energy resources, especially, satisfaction of energy resource had significant differences.

The purpose of this study was to investigate the preferred clothing images and clothing behaviors on personality types. Personality types were applied using Myers-Briggs Type Indicator(MBTI). Clothing image preferences were measured using 28 adjectives of 5-point scales. The data were collected from 101 female using questionnaire to prefer on clothing images, consumer information sources and retail store types. The data analysed with crosstab analysis, t-test, MDS. Extroversion and Introversion had significant difference in casual, sporty, fresh, youthful, western, and simple more than introversion types. Sensing and intuition had significant difference in feminine and strong image. Sensing types were significantly evaluated feminine style more than intuition types. Thinking types were significantly evaluated simple image more than feeling types. Judging and perceiving had significant difference in graceful, lofty, and strong image. Judging types were significantly evaluated graceful and lofty style more than perceiving types.

본 논문에서는 이성간의 대화에서 여성을 상대로 이성에 대하여 관심이 있을 경우와 관심이 없을 경에 따른 성문 특성변화를 비교 연구하였다. 대화내용을 녹음한 음성신호의 분석을 거쳐 얻어낸 결과로부터 보면 여성은 자신이 관심을 갖지 않는 상대에 대하여서는 17.2％ 미만의 응답을 보여주는 반면 관심이 있는 상대에 대하여서는 45.1％ 좌우 또는 그 이상의 응답을 보여주고 있다. 대화 내용의 음성신호를 스펙트로그램으로 표현 하였을 경우 성문 특성의 변화는 매우 뚜렷하다. 주파수 측면으로부터 보면 여성은 관심 있는 이성과 대화할 경우 200Hz에서 450Hz 좌우의 기본 주파수 폭을 이루게 되지만 관심이 없는 상대에 대해서는 200Hz에서 320Hz 정도의 기본 주파수 폭을 나타내게 된다. 따라서 이성간 대화에서 이러한 성문 특성의 변화를 이용하여 상대방 호감도를 측정할 수 있는 제품 개발에도 본 논문에서의 연구내용이 용이하게 쓰일 것으로 예상하고 있다.

During driving an automobile, drivers push the clutch and transmit gear by their feeling. At the automobile which have the manually operated gear box by using apart designed equipment, for get the semi-auto function, a lot of research to realize the system which have passive transmission and automotive transmission has developed. In this paper, basically using one chip .mu.-comcontrolled the clutch of automobile by means of LPF, F/V converter and TR driver circuit which is designed. In the past, it was controlled the motor by operating relay which is int eh output system to control the clutch. This system some noises is made by on and off the relay, lessen the motor speed and causes many error due to consume the large power on driving the motor. In this paper, to solve these problems the output TR is operated by using one chip .mu.-com decrease the electic power consumption and designed the actuator to control the clutch by measns of vacuum.

A new monitoring system is proposed to give direct visual information of the remote site when working with a tele-operation system. In order to have a similar behavior of a human when he is inspecting an object, multiple cameras that have different view point are attached around the robot hand and are switched on and elf according to the operator´s motion such as joystick manipulation or operator´s head movement. The performance of the system is estimated by performing comparison experiments among single camera (SC) vision system, head mount display (HMD)system and proposed multiple camera (MC) vision system by applying a task to several examines. The reality, depth feeling and controllability are estimated for the examines ...
