영상에서 음악의 역할은 영상의 내러티브를 표현하는 보조적인 기능 또는 음악의 주체가 되어 영상을 주도하는 독립적인 기능으로 구분할 수 있다. 소리를 청각으로 감지하여, 이를 시각화하는 작업을 비쥬얼 뮤직이라고 한다. 19세기 이후 예술가들에 의해 색청(色聽)을 통한 음악의 이미지 동기화 시도는 작품을 통해 끊임없이 이루어져 왔다. 또한 20세기 들어 영화의 발전으로 많은 예술가들은 3차원적인 표현의 한계에서 벗어나 움직임의 시간적 개념을 시도할 수 있게 되었다. 이러한 과정 속에서 실험정신이 강한 예술가들은 소리와 영상의 상관관계를 추론하여 비쥬얼 뮤직이라는 새로운 장르를 개척했다. 그 결과 과거 듣는 음악의 시대에서 현재 보는 음악의 시대로 바뀌고 있으며, 음악과 영상의 실험적인 시도로 다양한 작품들이 제작되고 있다. 본 논문은 현대의 비쥬얼 뮤직의 미학적 특징을 살펴본 후, 색을 활용한 비쥬얼 뮤직이 영화, 애니메이션, 뮤직비디오, 미디어 아트 등 다양한 분야에서 어떻게 활용되고 있는지를 비교, 분석하고자 한다.

최근 고화질의 카메라가 장착된 휴대폰이 빈번하게 출시되고 있다. 휴대폰으로 고화질의 동영상 촬영은 가능하지만 그 동영상을 컴퓨터와 휴대폰 이외의 다른 영상장치에서는 무선 전송을 통해 재생시킬 방법이 없다. 따라서 본 논문에서는 휴대폰으로 촬영한 동영상을 고정식 TV뿐만 아니라 이동식 TV에서도 재생 가능케 하는 NTSC TV transmitter module을 설계 및 제작하고자 한다. NTSC transmitter module은 휴대폰에서 재생되는 동영상의 영상 및 음성 신호를 받아 NTSC TV의 CH4 방식으로 변조한 뒤, 이 신호를 무선으로 전송함으로써 TV에서도 휴대폰 동영상을 시청할 수 있다는 장점이 있다. 그러나 NTSC TV transmitter module은 안테나의 길이가 길고 잡음에 민감한 단점이 있다. 향후 TV 신호의 송수신 RF 분야의 지속적인 연구를 통해 안테나의 설계와 TV 신호의 왜곡 및 잡음 문제를 해결한다면 본 NTSC TV transmitter module은 휴대폰뿐만이 아닌 캠코더, DVD 플레이어 등의 많은 영상기기에 응용 가능할 것으로 예상된다.

The primary purpose of this study was to develop an educational tool that can be used in teaching young children about different types of sex roles. The secondary purpose was to observe and analyze the effects of watching different sex role video programs on preschool children's sex role stereotypes and to determine the lasting effects. The subjects of this study were 89 six year-old kindergarten children, forty five were girls and forty-four boys. Each child was interviewed individually and tested at three different points in time: 1 week before the treatment, immediately after the treatment, and 4 weeks after the treatment. Three different statistical procedures were used in analyzing the data: ANOVAs for sex differences in sex role stereotypes. ANCOVAs for the different effects of traditional sex role programs and reversed sex-typed sex role programs, and ANCOVAs and Lindquist type III ANOVAs for the lasting effects of the treatment. The findings of the study indicated that (1) the children showed sex differences in the scores of sex role stereotypes of own, opposite sex and child activity; (2) there were differences in the scores of sex role stereotypes in terms of own and opposite sex. That is, viewing the reversed sex-typed programs caused a decrease in children's sex role stereotypes; and (3) the traditional and reversed sex-typed sex role programs tested four weeks after treatment showed significant lasting effects of sex role stereotypes in terms of opposite, composite and adult activity. In conclusion, the results of this study suggest that the sex stereotypes of kindergarten children can be changed through sex role VTR programs.

When women are removed with their matrix which is a emotionally significant organ of symbol in psychologically adapting themselves to mother and woman, that is threatened and injured with woman role decisively. This study tried to find the efficient nursing intervention method to maintain and promote their health, to cope with health problem, and to inquire into the loss experience of women with hysterectomy by using the phenomenological method. The analysis of the data was made through the phenomenological analytic method suggested by Giorgi. The result of the study was as follows : The factors which have influence on the loss experience of the subjects are an offer of information, support system, age, occupation, economic situation, family history, character, season, the existence of ovary and religion. The loss experience of matrix was expressed in lingual, reactions to the loss of function, sex, body change and husband, in behavioral behaviors in emotion and body. The loss of matrix of the subjects was relived by religion. perineorrhapy, exercise, reading, watching video and diet. The subjects each showed ways of reaction of fatalism, giving-up, coping on the loss experience of matrix. In conclusion, since we ascertained that the nursing in the process of recovery decide the quality of life. though women with hysterectomy undergo various loss experience and adapt to it in the end, it is necessary to give them enough information and educate husband, having on important effect on the loss experience, to be a good supporter, And technically skilled nurses of consultant are thought to be able to contrive better qualitative life of women with hysterectomy as an important bridge between the subjects and their required information, since the nurses have their well-formed position of relationship of confidence through continuous contact with patients and their family.

The prevalence of obesity in children has steadily risen during recent years in developed countries. Child obesity has become a major concern to health providers since it has grown to epidemic proportions over the past few decades. This study was conducted to investigate the biochemical status, dietary habits and life styles according to the obesity degree among obese children residing in the Gyungbuk area. The subjects were 148 elementary school students (boy 103, girl 45) and classified as mildly obese (n = 56), moderately obese (n = 61) and severely obese (n = 31) by the obesity index. The average body weight and height increased significantly according to the obesity degree (p < 0.05, p < 0.001). Serum cholesterol concentration came under the normal level in all groups. Serum AST activity increased according to the obesity degree but it was not significant. Serum ALT activity increased according to the obesity degree (p < 0.05). Dietary habit score was lower significantly according to the obesity degree (p < 0.01). Life style of the subjects was significantly different for the level of 'healthy state (p < 0.05)', 'body perception (p < 0.01)', 'watching TV and video (p < 0.05)', 'normal sleeping hour (p < 0.05)' and 'degree of stress (p < 0.05)' according to the obesity degree. A positive relationship between obesity index and blood pressure, ALT has been shown in the subjects. Obesity index and dietary habit scores were negatively associated. Therefore, these results suggest that a practical nutrition-exercise education program for the prevention of child obesity should be provided to elementary school children.

The necessity of school health promoting projects is well known to many researchers, however, there is a lack of research on the development of strategies for school health programs and the evaluation of the effectiveness of the programs. The results of our previous study in 1996 identified poor eyesight as one of the several health problems among elementary school children in urban areas. The main objective of this study is to develop, implement, and evaluate vision care for elementary school children. The research method utilized a quasi experimental design using non-equivalent group, pre-post comparison. The sample consisted of all second grade children in two elementary schools in Kyung-giProvince. In order to prevent a contamination effect of the vision care program, one school was selected as a control and the other school was selected as a treatment group. The experimental school had 467 children and the control school had 402 children. The visual acuity of children in both group was measured and a survey questionnaire was sent out to parents on the knowledge, attitude, and behavior related to vision care before the program was implemented. The children of the experimental school received the following programs; separate education on proper nutrition and care of eyesight for children and parents, daily eye exercises using video tape, and an essay and poster contest on healthy eyesight. The eye exercise program lasted from March, 1997 to November, 1997. On November, 1997, visual acuity was measured again from children in both schools. The data was analyzed by using SAS statistical package. The results indicate that the children in the experimental group had significantly (p〈0.001) better eyesight than the children in the control group. Also, some of the behavior highly related to the poor eyesight are poor maternal eyesight and watching TV from a short distance. In conclusion, one of the significance of this project is that the vision care program was developed after the need assessment. It will be encouraged in the future that more school health program should be developed after a need assessment. Also, inclusion of family members was important in health promoting projects within a school setting since healthy behavior needs to be reinforced at horne as well as at school.

The previous studies showed that the visual imagery activated the occipital and posterior inferior temporal area of the brain, and the damage to the occipital cortex impaired the visual mental imagery. We studied current-source distribution of electroencephalography (EEG) to observe neuronal activity during imagery tennis playing. Eleven healthy volunteers were enrolled. All volunteers were right-handed males and novices for tennis playing. The mean age of them was 24.9 years. The EEGs were recorded on the scalp electrodes located according to the International 10~20 System. The number of electrodes was 25 channels including subtemporal electrodes. The EEG recording session was 13 min including 5 segments: resting-I, scenery-slide show, resting-II, watching tennis-game video, and imagery-tennis playing. The recoding durations were 3, 2, 3, 2, and 3 min respectively. Five 'artifact free 3-sec segments' were selected in each segment of 'imagery-tennis playing' and 'resting-II'. We did the frequency domain analysis with the EEG segments using a distributed model of current-source analysis. The statistical-nonparametric maps (SnPMs) were obtained between the segments of 'imagery-tennis playing' and the segments of 'resting-II' (p<0.01). The significant change of current-source density was observed only in alpha-2 frequency band (10~12 Hz). The current-sourcedensity was increased in the hippocampus, parahippocampus, and occipital fusiform gyrus in the right cerebral hemisphere (p<0.01). Imaginary-tennis playing may activate the hippocampal-occipital alpha networks of nondominant hemisphere.
