The purpose of this study were to find out the practical way to enlarged child-raising knowledge and to enhance their satisfaction with out-patient care by evaluating how effectively the education is done by nurses for mothers with ill-child and how their satisfaction with out-patient care changed. This study was designed as a Nonequivalent Control Group study. The subjects studied were consisted of the experimental and control group. Each consisted of 50 mothers with ill-child in pediatric department at one university hospital in Seoul. The period of this study is from May 20, 1996 to J one 28, 1996. The first data were collected from both of experimental and control groups in which mothers with ill-child come to the hospital for the first time. After this being done, the experimental group had been educated by the planned program and then the second data were collected from them. On the contrary, as for the control group, there had been no education and the second data were col looted on the same method. The data analysis was done by SPSS program. The results of this study are as follow, 1 The child-raising knowledge level of mothers with education was higher than that of with no education. (t=18.84, df=49, p=0.000) 2. The satisfaction with out-patient care level of mothers with education was higher than that of no education. (t=10.51, df=49, p=0.000) Based on these results, I suggest as follow, 1. The research on the patients and their family should be made not only in pediatric department, but in every out-patient department. 2. For more effective education, it is required for all out-patient nurses to research the education demand of patients and their family. 3. To increase the effect of education, there must be the consultation room in out-patient department. 4. The meetings with the mothers with ill-child of the same illness have to be established and periodical education must be executed. 5. Audio-visual education programs like video tapes are needed to make use of waiting time for the medical treatment. 6. On-line consulting programs are needed.

This paper proposed the content-based retrieval system as a method for performing image retrieval through the effective feature extraction of the object of significant meaning based on the characteristics of man's visual system. To allow the object region of interest to be primarily detected, the region, being comparatively large size, greatly different from the background color and located in the middle of the image, was judged as the major object with a meaning. To get the original features of the image, the cumulative sum of tile declination difference vector the segment of the object contour had and the signature of the bipartite object were extracted and used in the form of being applied to the rotation of the object and the change of the size after partition of the total length of the object contour of the image into the normalized segment. Starting with this form feature, it was possible to make a retrieval robust to any change in translation, rotation and scaling by combining information on the texture sample, color and eccentricity and measuring the degree of similarity. It responded less sensitively to the phenomenon of distortion of the object feature due to the partial change or damage of the region. Also, the method of imposing a different weight of similarity on the image feature based on the relationship of complexity between measured objects using the fractal dimension by the Boxing-Counting Dimension minimized the wrong retrieval and showed more efficient retrieval rate.

The purpose of this study was to develop concrete and in-depth knowledge about menarche and to raise the need of menstrual education. The data were collected from purposively sample 34 women from twenties to forties from April 27 to October 10, 1994. Semi-structured intensive interviews were done and these qualitative data were analysed with "Ethnograph" computer program. The results of the study were as follows : 1. The experience of menarche could be classified into two main groups, which were positive and negative response to menarche. The negative experiences were to be shameful, tearful, scared of the phenomena and thought as a kind of punishment for guilt or confused menarche with other symptoms of diseases. On the contrary, the positive experiences were to be proud of physical maturity and to think that is was wonderful, miraculous and to perceive it as a warm experience. 2. The experience of menarche was influenced by various factors. They were the knowledge about menstruation, the quality and amount of informations, the time of menarche, the environmental factors, the response of significant others toward menarche. The experience of menarche could be positive or negative according to these factors. 3. The previous information sources about menstruation could be significant others, school education and mass-media. The significant others were mothers, sisters, friends and the person in charge of school sex education such as school nurses, home economics, military drill and athletics of teachers. And mass-media included sex education booklets, nursery tales, TV programs, and publicity activities of sanitary napkin companies. 4. The opinions of the subjects about the proper time of menarcheal education could be grossly classified into two groups. The first was active approach toward children when they were in elementary school. The second was passive approach which postponed the time until the child ask about it, because it would be awkward for them to discuss about the topic. 5. The participants thought that the ideal methods of menarche education would be systematic school education programs, open discussion with daughters, audio-visual teachings, or practical education in everyday life. 6. The contents of the menarche education based on the participants' opinions, would be positive details about meanings and functions of menstruation. And it would be desirable if the attitudes of the person in charge of education could be positive, open-hearted, and favorable toward menstruation.

Objectives : The purpose of this study was 1) to investigate the possibility of taking blood stasis pattern as a clinical parameter of frozen shoulder, using blood stasis pattern questionnaire (BSPQ) to frozen shoulder group comparing with normal group, and 2) to find out the relationship of the severity of main frozen shoulder symptoms (pain and limited range of motion of shoulder) and the level of blood stasis pattern through BSPQ analysis. Methods : During the period of January 2010 to July 2010, fifty five frozen shoulder patients who visited outpatient clinic of department of acupuncture and moxibustion in East-West Neo Medical Center, Kyung Hee University and fifty five normal people without shoulder pain nor limited ROM in shoulder joint were evaluated through BSPQ, and to the frozen shoulder group, also evaluated three different visual analogue scales (VAS) of pain (pain on average, pain at night, and pain on motion) and active / passive range of motion (ROM) of shoulder joint. Results : Mean blood stasis pattern score of frozen shoulder patients group was significantly higher than the score of normal group (patients vs normal group : $4.85{\pm}1.68$ vs $3.49{\pm}1.54$). Three different types of pain VAS (on average, at night and on motion) showed low to very low positive correlation with BSPQ scores when analyzed with Pearson's correlation coefficient. ROM levels in shoulder joint were not significantly related to BSPQ scores, though active external rotation range showed low positive correlation with BSPQ scores. Conclusions : Patients with frozen shoulder showed higher blood stasis pattern score in BSPQ but the level of blood stasis pattern is not significantly related to the severity of pain or limitation of ROM in shoulder joint.

Traditionally, keyboards have been one of the most frequently used input devices for information processing using computers. As most computers adopt the Microsoft Windows for their operating system however, the usage of mouse has recently increased to a great extent. Moreover, the mouse has been used as the leading input device in such areas as industrial design and computer aided design. Excessive uses of mouse may cause a severe pain and fatigue on neck and upper limb due to the intensive and repetitive use of corresponding muscles, which renders a decline in efficiency and leads to musculoskeletal disorders. The main purpose of this study is to find the best working conditions to prevent musculoskeletal disorders when using mouse in a neutral posture. Utilizing electromyogram amplitude and Borg's scale, the role change and strength imposed on the muscles were measured and analyzed with and without the forearm support concerned. Also investigated were the effects of changes in elbow forearm supporter.

Our study investigated the association between solvent exposure and acquired color vision loss using the Lanthony D-15 desaturated panel in petrochemical industry. Since neurotoxic effects associated with chronic solvent exposure, subjects with more than 6 months of exposure were included. Exposure assesment was estimated mean, maximum and cumulative 8hr TWA from individual 8-hour sampling. Exposure status were classified into two groups, occupationally exposed group to solvent and a non-exposed group. The results showed that CCI was positively related for age. According to the results of qualitative analysis, there was no significant difference in the prevalence of specific Type of dyschromatopsia the two examined group. However, the prevalence showed a higher proportion of dyschromatopsia to solvent exposure. It was affect with acquired dyschromatopsia(Type II, III and Complex) in exposed worker group(5.9%,7.86%,14.99%, respectively) than in the nonexposed group(6.16%,7.55%,13.71%, respectively). After each variable was adjusted for age, alcohol and tobacco consumption, a relationship between acquired dyschromatopsia and exposure showed an increase in the Odds ratio as compared to the nonexposed group at only left. The results showed that acquired dyschromatopsia was positively related to age (p<0.001). The results showed that solvent exposure, although not significant, could cause the acquired dyschromatopsia and visual system can serve important information on early neurotoxic effects in generally. Therefore, we need to concerns about eye health in workers.

With entering the 21st century, modern people's dark inside and panic are emerging as the talking point on the theater stage. Even in the field of stage costume, the necessity of a research is being demanded through analyzing on psychological anguish and structure of characters. Accordingly, this study aims to allow the stage costume design to be expressed a human being's Doppelg$\ddot{a}$nger Image, which was elicited through analyzing a work of the play titled Le Grand C$\acute{e}$r$\acute{e}$monial by a playwriter Fernando Arrabal, who draws the conflictory and contradictory duplicity, which positions in a human being's deep inside by having chaos as catalyst. A research subject is 'Le Grand C$\acute{e}$r$\acute{e}$monial,' which was staged as the winter performance in commemoration of the 50th anniversary for the foundation of Dept. of Theater, Chung-Ang Univ. in November 2009. Psychology of characters in a play, which varies dimensionally, could be delivered, as nonverbal element called costume, by applying costume design of Cavanoza, Syl, Nice to Doppelg$\ddot{a}$nger Image such as Innocence vs Cruelty, Purity vs Superficiality and Restraint vs Freedom, which were elicited through analyzing characters. Through this study, the costume, which was expressed by visualizing a human being's Doppelg$\ddot{a}$nger Image, could be known to function as important dramatic factor of allowing character's psychology to be understood through costume as well as functioning as visual and sensible language, which is important for communication with the audience. A research on costume design, which reflects a character's complex inside, is expected to be likely continued through in-depth analysis on a playwriter's intention and on the appearing characters at the current point of time when an active research is being performed on stage costume in the wake of this study.

The application of more complex radiotherapy techniques using multileaf collimation (MLC), such as 3D conformal radiation therapy and intensity-modulated radiation therapy (IMRT), has increased the significance of verifying leaf position and motion. Due to thier reliability and empirical robustness, quality assurance (QA) of MLC. However easy use and the ability to provide digital data of electronic portal imaging devices (EPIDs) have attracted attention to portal films as an alternatives to films for routine qualify assurance, despite concerns about their clinical feasibility, efficacy, and the cost to benefit ratio. In this study, we developed method for daily QA of MLC using electronic portal images (EPIs). EPID availability for routine QA was verified by comparing of the portal films, which were simultaneously obtained when radiation was delivered and known prescription input to MLC controller. Specially designed two-test patterns of dynamic MLC were applied for image acquisition. Quantitative off-line analysis using an edge detection algorithm enhanced the verification procedure as well as on-line qualitative visual assessment. In conclusion, the availability of EPI was enough for daily QA of MLC leaf position with the accuracy of portal films.

The study subjects in this study are 295 workers who work on one electronics industry, and they were composed of 93 VDT and 202 non-VDT workers. This study was carried out to obtain the prevalence of subjective symptoms and to compare psychological symptom scores from SCL-90-R between VDT and non-VDT work groups. And to verify the relationship between VDT work related symptoms and psychological symptoms, the author compared SCL-90-R T scores between symptom complaining and non-complaining groups. The results are summarized as follows : 1. Throughout the prevalence study of VDT work related symptoms according to VDT work state, the author could select the final 10 symptoms by sex;'eye fatigue', 'foggy vision', 'neck discomfort or pain', 'shoulder discomfort and pain', 'light headedness', 'dizziness', 'acne', 'itching sensation on face', 'difficulty in concentration', 'memory disturbance' in males, and 'blurred vision', 'foggy vision', 'neck discomfort or pain', 'shoulder discomfort and pain', 'abdominal distention', 'indigestion', 'acne', 'prickling sensation on face', 'difficulty in concentration', 'memory disturbance' in females. 2. Throughout comparison of psychological symptom scores from SCL-90-R between VDT and non-VDT workers, except 'Interpersonal sensitivity' in female, Mean T score were higher in VDT workers, but not significantly different between the two groups. These results indicate that the relation between VDT work status and psychological symptoms are not strongly correlated. 3. Because of the nonspecific characteristics of VDT work related symptoms, from the 40 subjective symptoms, the author selected the final 10 symptoms by sex, especially correlated to VDT, and divided the study subjects into symptom complaining and non-complaining groups. The mean SCL-90-R T scores between the two groups were compared. Except for the opthalmologic symptoms in females, the scores were significantly different between the two groups in all symptoms. And this indicates that the VDT work related symptoms strongly correlated with the present individual psychological conditions. 4. Due to understand that which of the 9 psychological symptom dimensions are strongly correlated with the subjective symptoms, the author excuted muliple logistic regression analysis, and the result were as follows; 'depression' and 'somatization', in male, and 'obsessive-compulsive' and 'somatization' in female.
