The purpose of this study was to find a method for improving the children's behavior during dental treatment in relation with dentist's attire. For this study 150 children, visiting a dental clinic, were asked to participate in a survey on the attire of the dentist. The results of the survey were as follows: 1. In the survey for the preference between gown and ordinary clothes according to sex(P<0.05), age(P<0.05), residence (P<0.05) and number of visits(P<0.05), there was more preference for gown(65.3%). 2. The preference for the type of gown and attire under the gown was a long gown and white shirt (30.7%), followed by a suit-like gown (18.7%) and white shirt, and long gown and polo shirt(17.3%). 3. The preference for the color of gown was white(34.7%), followed by pink (18.7%), green(18.0%), blue(15.3%) and yellow(13.3%). 4. The preference for the pattern on the gown was cartoon characters(49.3%), followed by hospital logo(28.7%) and no pattern(14.7%). 5. The preference for ordinary clothes of female dentists was polo shirt(37.3%), followed by striped shirt(28.7%), round T-shirt(18.7%), and everyday Korean traditional dress(15.3%). 6. The preference for ordinary clothes of male dentists was pattern necktie and no pattern Y-shirt(28.0%), followed by no pattern necktie and Y-shirt(21.3%) or pattern shirt with no necktie, and no pattern Y-shirt with no necktie(14.7%). 7. The preference on the protective equipment worn was mask and glove(28.7%), followed by no protective equipment(26.7%), mask, glove and protective glasses(22.7%) at)d only mask(22.0%). Based on the above results, it seems that parting with the traditional white gown and wearing multi-color and pattern attire will provide psychological stability and help improve children's behavior during treatment.

기존에 사용자 인터페이스 디자인 개발시 다양한 사용자 니즈들이 수집되고 이러한 정보들의 효과적 활용을 위하여 여러 가지 분석방법들이 활용, 개발되고 있다. 그중 Video Ethnography는 특정 시스템 상에서 나타나는 사용자의 행동을 중심으로 한 환경내의 변화를 비디오를 이용해 저장하고 저장된 상황 의 변화요인을 해석 체계에 의거해 분석하는 기법이다. 이는 기존의 다른 방법에 비해 사용자의 자연스 러운 작업의 수행을 분석하는 데 초점을 맞추고 있기 때문에 실험실에서 행해지는 계획된 실험에서 얻 을 수 없는 시스템에 관한 발견점을 찾아낼 수 있다는 장점이 있다. 하지만 현재 Video Ethnography를 수행하는 과정에서 수집된 사용성 정보들이 총체적인 관점에서 체계적으로 관리, 분석되지 못하고 있고, 관리 시스템의 부재로 인하여 비디오 데이터를 분석, 관리하는데 필요이상의 시간과 노력이 필요한 실정 이다. 본 연구에서는 이러한 어려움을 해결하고자 Video Ethnography를 통해 얻어진 사용자 니즈를 체 계적으로 수집,해석, 관리하는 효과적인 도구의 개발에 중점을 두었다. 특정한 사용상황에 맞추어 수집 된 다양한 형태의 사용자 니즈들은 먼저 컴푸터를 통해 입력되고 입력된 데이터는 과업의 목적, 주변상황, 시스템과 사용자와의 상호작용 등 다양한 변수에 의해 분석된다. 이러한 분석의 과정을 통해특정 시스템 에 대한 사용자의 니즈가 도출되고 새로운 디자인 해결안이 제시될 수 있는 것이다. 이러한 일련의 과정 은 사용자 니즈 데이터베이스로 구축되며 추후 제품 개발의 근거로서 활용될 수 있다. 앞으로 다양한 사 용환경에 대한 사용자 니즈 데이터베이스가 확충되면 각 사용상황하의 사용성 문제 해결안뿐만 아니라 서로 관련이 있는 사용상황간의 연계 연구를 통해 좀 더 광범위한 개념의 제품 개발도 가능해 질 수 있을 것이다.와 만족도와의 관계 및 이상형에 대해 구체적으로 파악할 필요가 있다. 또한, 신체에 대한 이상형은 시대의 여러 여건에 따라서 변화할 수 있으므로 의복 착용자가 의복을 통해서 표현하고자 하는 이상형의 시대적 변화를 살펴볼 필요가 있다. 따라서 본 연구에서는 신체에 대한 인식도 및 만족도, 이상형에 대한 설문지 조사와 신체측정을 통하여 신체 크기에대한 만족도를 객관적인 척도로 고찰하고, 이상형과 실제 체형에 관하여 고찰하고자 한다. 도한, 1992년도 자료와의 비교를 통하여 시대에 따른 신체만족도와 이상형의 변화를 파악하고자 한다. 이를 기초로 한 의복원형 제작 및 의복 디자인에 대한 연구를 통해 의복의 맞음새가 좋을뿐만 아니라 의복착용자들 에게 심리적 만족을 줄 수 있는 의복 제작에 도움이 될 수 있을 것이다.적입지로 분석되었다.등 다양한 모형들을 고려해 본 뒤, 적절한 모형을 적용할 것이다. 가로망 설계 모형에서 신호제어를 고려하기 위해서는 주어진 가로망에 대한 통행 배정과정에서 고려되는 통행시간을 링크통행시간과 교차로 지체시간을 동시에 고려해야 하는데, 이러한 문제의 해결을 위해서 최근 활발히 논의되고 있는 교차로에서의 신호제어에 대응하는 통행배정 모형을 도입하여 고려하고자 한다. 이를 위해서 지금까지 연구되어온 Global Solution Approach와 Iterative Approach를 비교, 검토한 뒤 모형에 보다 알맞은 방법을 선택한다. 차량의 교차로 통행을 고려하는 performance function의 경우 비신호 교차로와 신호교차로에 대한 적절한 비교가 현재로서는 고려되고 있지 못하기 때문에, 구성되는 가로망의 경우 신호교차로들로만 구성되며, 부득이한 경우 입체교차의 형태로 구성되는 것으로 가정한다. 실제 가로망의 경우, 교통향이 많은 도시부의 경우 주가로망은 대부분 신호교차로와 입체교차로 구성되기 때문에

The purpose of this study is to satisfy students in adolescent trends of school uniforms and to provide them with useful material with matching current fashions by analyzing the attitude of students toward uniform transformation in female highschool students and investigating factors influencing on behaviors of uniform transformation. The subjects of this study are 30 students in Daegu with the basic ways of investigating such as depth interview and survey. The results are as follows; First, students agree to wearing school uniforms. As the main reason for wearing school uniforms, students put emphasis on peer pressure. It is also analyzed that the figure of students' body have some influence on the attitude of students toward wearing uniform while students' appearance have no influence on the attitude of students toward wearing uniform. Second, students showed high satisfaction in school uniforms. While students are satisfied with design and color of school uniform, they are not satisfied with practicality, economic efficiency and the quality of textile. Third, the study shows most students have experience of uniform transformation as a result of depth interview about actual condition of uniform transformation. Whereas students usually wear the jacket with its width and length shortened, they tend to lengthen skirt and unstitch pleat of skirt. Fourth, there are many reasons for uniform transformation as a result of depth interview with students. Transformation for satisfying aesthetic desire tops the list, followed by transformation for matching, transformation for peer pressure. As shown by the results above, every school needs to make various efforts to satisfy students, teachers and parents by considering and using students' opinion in order to choose the better school uniforms. In addition, the study related to school uniform transformation need to have more various investigating ways to acquire more authentic results such as expanding the subjects to not only students but also teachers and parents and in-depth comparison between subjects.

The purpose of this study was to investigate the association factors of dental infection control by applying the health belief model in the dental hygienists. This study subject was 142 dental hygienists from 15 to July 5, 2020. Data were analyzed by chi-square test ANOVA, correlation analysis, and multiple regression analysis using SPSS version 23.0. The performance of dental infection control in accordance with the general characteristics of research subjects was high in case when they had educational experiences of infection control, and when they 'always' did medical examinations by interview about infectious diseases(p<0.01). The group of dental hygienists working for dental clinics with less than average 50 patients a day showed the highest rate of wearing a mask and latex gloves as personal protective gears(p<0.05),(p<0.01). When the wearing of protective goggles(face shield) and the frequency of exchanging masks after the outbreak of COVID-19 were more, the performance for infection control was increasing(p<0.05),(p<0.01),(p<0.001). In this study, it is difficult to generalize the results of the study because the research area and the subject are limited by selecting the subjects by convenience extraction, and focusing on the degree of awareness of infection control by dental hygienists, the actual status of infection control in dentistry is carefully illuminated. What you didn't do can be seen as a limitation. Considering the results of this study, the performance of infection control could be increased by removing obstacles and increasing the importance and perceived benefits of infection control of dental hygienists.

We propose the ubiFloor system to track and recognize users in ubiquitous computing environments such as ubiHome. Conventional user identification systems require users to carry tag sensors or use camera-based sensors to be very susceptible to environmental noise. Though floor-type systems may relieve these problems, high cost of load cell and DAQ boards makes the systems expensive. We propose the transparent user identification system, ubiFloor, exploiting user's walking pattern to recognize the user with a set of simple ON/OFF switch sensors. The experimental results show that the proposed system can recognize the 10 enrolled users at the correct recognition rate of $90\%$ without users' awareness of the system.

The purpose of this study was to better assess and understand current needs and wearing sensation, including clothing behavior for early elderly women in the Korea and USA. The subjects in this study were 135 and 173 early elderly women in the Korea and USA. This research was done by a survey method and chi-square test. The major objectives of this study were as follows; First, it was found that the early elderly women of Korea utilize mostly human information as information source when purchasing clothing, whereas those of USA mostly media information. The women of Korea were found to put most emphasis in esthetic aspects of clothing, whereas those of USA in comfort. The most frequently worn clothes by the early elderly women of Korea were jumper, T-shirt and slacks, whereas jacket, sweater and slacks by those of USA. As for skirt, flare skirt was highly preferred in Korea, whereas A-line skirt in USA. Second, regarding the wearing sensation of ready-made clothing, the wearing sensation of jacket was found to be worst on the shoulder in Korea, whereas on the waist in USA. And the early elderly women of both Korea and USA had poor wearing sensations due to the length of sleeve, of trouser, of skirt and of one-piece dress. The comparison of the clothing behavior and wearing sensation of the early elderly women between Korea and USA showed a greater difference in clothing behavior than in wearing sensation.

The purpose of this study was to investigate use and purchase behavior of sleeping wear for summer. Subjects in this study were composed of 591 males and females aged from twenties to fifties, living in Taejon and Chongju. For data analysis, descriptive analysis, $\chi$$^2$-test, t-test, ANOVA, and factor analysis were used. The results are as follows. First, subjects used sleeping wear(a night gown and pajamas), and home wear(T-shirts and sweat suit with zippered top) with similar rates. The subjects, who are females, married, older and have professional jobs, owned sleeping wear such as a night gown and pajamas more than home wear. Also, the mean of using pajamas was the highest, and they were satisfied with them more than others who didn't wear them. Second, one-third of consumers purchased sleeping wear once a year in a specialty store. Consumers mainly searched for information regarding sleeping wear in the display section. Most consumers weren't influenced by others when they made their purchases. When consumers decided to purchase a product, they considered six criteria such as fabric/management, wearing/fitness, esthetic, service, symbolic status, and economic for evaluating. Among them, the factor wearing/fitness was considered the most important. These results imply that consumers would be conscious of sleeping wear even though sleeping wear and home wear are used interchangeably. In addition, consumer behavior concerning sleeping wear is different from their characteristics such as sex, age, occupation, the level of education, and marital state. Therefore, the markets with sleeping wear would be able to be segmented based on consumers’characteristics. Also, marketers should focus on distribution channels to reform the markets of sleeping wear, that is, they may offer products in specialty stores. Additionally, market managers would be able to concentrate on visual merchandising in stores in order to increase brand awareness and market share.

The puropse of this study is to find out that whether the juvenile delinquency could be decreased by the revival of school uniform for the high school students. For this purpose, the difference and frequency of juvenile delinquency between uniformed students and none·uniformed students were surveyed. In addition, the relation among the students, social classes, receiving attitude for the sub-culture, with juvenile delinquency were also surveyed. For this study, 728 high school students were' studied with a questionaire. They were 328 ' uniformed students from 6 schools and 400 none-uniformed students from other 6 schools. The conclusions of this study are as follow: 1. The order of juvenile delinquency is resistance to their parents and teachers, cunning in examination, drinking, watching shameful video tapes, possession of dirty books and pictures, gambling, entering to thea rooms, billiard rooms, the prohibited cinema houses aild drinking houses, and smoking. The students' delinquency was chiefly misdeed against the public order and social position and most of them were without any victims. And there were no misdeed such as drug addiction, robbrry and bodily harm. 2. The difference of juvenile delinquency between uniformed and non·uniformed schools was not found. 3. More nisdeed were occurred when they were without uniform; especially in cases of entering to shameful video shops, drinking houses, tea rooms and billiard rooms. 4.The logical propriety that the juvenile delinquency would be decreased by putting on uniform to all students is scarce, because Ell misdeed were occurred when they were without uniform after school. Uniform were worn only when they go to school. 5. A negative effect between student's affection toward their parents and schools, and juvenile deliquency was found. Much they love their parents and schools, less misdeed occurred. 6. Positive effect between sub·culture and juvenile delinquency was found. The friendship with delinquent students gives a great influence to juvenile delinquency.
