  • Purpose: Because of limitation of image acquisition method and acquisition time, scatter correction cannot perform easily in SPECT study. But in our hospital, could provide to clinic doctor of scatter corrected images, through introduction of new generation gamma camera has function of simple scatter correction. Taking this opportunity, we will compare scatter corrected and non-scatter corrected image from image quality of point of view. Materials and Methods: We acquisite the 'Hoffman brain phantom' SPECT image and '1mm line phantom' SPECT image, each 18 times, with GE Infinia Hawkeye 4, SPECT-CT gamma camera. At first, we calculated each contrast from axial slice of scatter corrected and non-scatter corrected SPECT image of 'Hoffman brain phantom'. and next, calculated each FWHM of horizontal and vertical from axial slice of scatter corrected and non-scatter corrected SPECT image of '1mm line phantom'. After then, we attempted T test analysis with SAS program on data, contrast and resolution value of scatter corrected and non-scatter corrected image. Results: The contrast of scatter corrected image, elevated from 0.3979 to 0.3509. And the resolution of scatter corrected image, elevated from 3.4822 to 3.6375. p value were 0.0097 in contrast and <0.0001 in resolution. We knew the fact that do improve of contrast and resolution through scatter correction. Conclusion: We got the improved SPECT image through simple and easy way, scatter correct. We will expect to provide improved images, from contrast and resolution point of view. to our clinic doctor.

  • The slimness favored trend made students shape up body image by weight control using restrained eating. Many students especially female ones tend to be in eating disorder status. The aim of this study was to find the relation between weight, eating habits and dietary self efficacy in the selected middle school girl students group with high risk eating disorder (7.9%) and the one with low risk eating disorder (24.1%). This study was conducted by EAT-26 questionnaire method and all the data was analyzed by SAS (Statistical Analysis System) program. The results were as follows; The physical condition of eating disorder students (159.5cm height, 50.7kg weight and 97.4% PIBW) was higher and bigger than that of normal students(158.2 cm, 47.2 kg, and 92.6% PIBW). Weight control experience in the high risk group (69.4%) was significantly more frequent than normal group (p<0.001). The gap between actual body weight and desired weight was higher in high risk eating disorder group than in normal group (p<0.001). Dietary self-efficacy score of middle school female students in the high risk eating disorder group was high when they were in temper, in confusion, and after argument. However, when they were in cooking (p<0.01), with friends (p<0.05), in assembling dishes (p<0.01), and with family (p<0.05) the dietary self-efficacy score of high risk group was lower than that of normal group. In the high risk eating disorder group, eating speed was often faster (p<0.05) and overeating rate (p<0.01) was higher than in normal group. In general, EAT-26 score was correlated positively with gap weight, but negatively correlated with dietary self efficacy score(p<0.01). Gap weight and dietary self efficacy were significantly different in normal group. however, there was no relation in high risk eating disorder group. Under the circumstance of high risk eating disorder, as weight and dietary self efficacy did not affect the relation with eating disorder score, when it is determined as eating disorder some other factors besides weight and diet self efficacy seem to affect the eating disorder score. In conclusion, the factors related with eating disorder were gap weight and some items of dietary self efficacy. Thus, correct understanding of healthy weight and dietary self efficacy enhancement require the development of nutrition education contents and the practice of nutrition education.

  • The purpose of this study is to gather basic data on dietitian's general characteristics, working conditions, job achievement and job satisfaction. Thereby, a formulation can be worked out to improve dietitian's job achievement and satisfaction. The study was conducted during one week period, spanning July 23 to July 30, 1998. The method of the study was to distribute 560 questionnaires to the primary school dieticians working in the city of Tae Jun, located in Choong-Cheong Province. Out of 560 questionnaires that was distributed, 327 were returned. Moreover, 318 out of 327 questionnaires that was returned was valid enough to be processed by the SAS Program. About sixty percent of the respondents(61.1%) indicated that they were between 26 to 30 years old. Moreover, approximately half of the respondents(48.8%) were unmarried. In terms of the level of education, the bachelor's degree was reported as the most common education level(56.3%), while 3.8% of the participants reported achieving graduate degrees. The number of years in working in the profession ranged from 2 to 5 years. Furthermore, approximately 74% of the respondents indicated that, on average, they earned over ₩800,000 per month. In terms of the type of the school setting, 52.8% of the respondents worked in the urban setting, whereas, 60.0% worked in the rural school setting. Of these schools, about thirty eight percent(38.7%) of the schools were relatively small sized schools(400 students or less ). In terms of dietitian's sense of job satisfaction, the areas that showed relatively high level of satisfaction was in the menu control work(3.90) and purchase control work(3.90). However, appallingly low job satisfaction was indicated in the areas of personnel management (2.96%), and nutritional education and counsel(2.73%). Furthermore, job satisfaction varied greatly depending on age, wage, type of the food service, and type of school. The highest satisfaction was indicated in the areas of supervisory position(3.42), work itself(3.31%), co-workers(3.11). Other facets that led to job satisfaction were periodic wage increase(2.19%) and promotion opportunities(2.79%). In conclusion dietitian's job achievement showed significant correlation with job satisfaction. The study suggests that, in order to improve the overall job satisfaction of the dieticians, it is necessary to improve the working conditions of dieticians in primary schools. Secondly, there is a necessity for improving the status of the dieticians by raising the salary and treating the dieticians with the same level of respect in comparison with teachers or executive officials. Finally, another way of raising the job satisfaction of the dieticians is to provide opportunity for continuing education. So that, they can further their career in their chosen field.

  • The purpose of this study was to examine the stressors and coping strategies of school -age children and to explore the relationship between stressful life events and health symptoms and the effects of coping and trait anxiety which is theoretically considered to mediate the relationship between stress and health symptom. The study subjects consisted of 639 elementary school children in the fourth to sixth grade living in Seoul. Of the 639 subjects, 348 were boys and 291 were girls. The mean age was 11.35 (SD=.86). The Feel Bad Scale(FBS), Schoolager's Coping Strategy Inventory(SCSI), Spielberger's Trait Anxiety Scale for Children(STAIC), and Health Symptom Questionnaire (HSQ) were adapted for this study. A pilot study was undertaken to ascertain the reliability and validity of the instruments. The Cronbach alphas of FBS, SCSI, STAIC and HSQ were from .81 to .92. The Researcher and a research assistant visited the school and data were collected in the class using the questionnaire method after an explanation of the purpose and procedures was given to the children. Data collection was done during the period between Nov.25 to Dec.19, 1995. Using the SAS statistical program, percentages, t-test, ANOVA, correlation analysis, and multiple regression were used for data analysis. The result are as follows : 1. The mean score for the FBS was 204.79(range : 48-472) and there was a significant difference according to grade. The most severe stressors perceived by children were parental divorce and death or illness of family members. The most frequently experienced stressful life events were conflict with siblings and being home alone. 2. The mean score for the SCSI was 57.36(range : 9-118) and there was a significant difference according to grade. The most frequently used, and perceived as helpful, coping strategies were distraction and cognitive activities. 3. The mean score for the HSQ were 20.7(range : 0-81) and there were significant differences according to grade and sex. The percentage of the children answering that they perceived their health state as not good was 3.9%. 4. The mean score for the STAIC was 33.76 and there were significant differences according to grade and sex. 5. There was a significant relationship between stressful life events and health symptoms ( r=.53, p<.01). Also, Stressful life events were postively related with coping strategies(r=.39, p<.01). Trait anxiety was highly correlated with health symptoms(r=.72, p<.01). 6. To examine the multivariate effects of the variables to health symptoms, multiple regression was performed. Stressful life events, coping, trait anxiety, and health concerns were identified as significant variables. Explanation of the health symptoms by these variables was 56.78%. The study revealed that stressful life events correlated with health symptoms in school-age children and coping and trait anxiety had mediating effects on this relationship. The implication for nursing is that there is a need to develop supportive interventions for high risk population to decrease health problems due to stress. Also, it is recommended that a study be conducted to explore protective factors for the prevention of health problems in children.

  • The goal of this study is to discover the effect of sex education on sex-related knowledge and attitudes of middle school girls. Non-equivalent control group pretest-posttest design was used. The number of experimental group students was 134 and the number of control group students was 134. A total of 268 second grade middle school girls were selected for a convenience sampling method. This study was carried out in a middle school located in Taegu City, Korea, from February 5 to February 18, 1998. To des cover the needs of sex education, the researcher sent a predesigned questionnaire to 1464 girls in 19 different middle schools. The sex education curriculum was designed on the basis of this survey's results. 'The Sex Education Teaching Plan' (published by the Research Institution of Korean School Health Education) and 'Sex and Happiness' (published by the Seoul City Education Ministry) were used to redesign the sex education curriculum and content. Fifty minute long sex education classes were taught to the experimental group every other day and the total number of classes was five. The contents of the teaching -learning plan for sex education were: 'The Characteristics of Adolescence', 'Pregnancy and Contraception', 'Friendship with the Opposite Sex and Prevention of Sexual Violence', 'Prevention of Venereal Disease', and 'Sex and Society'. To measure the degree of sex knowledge of the subjects, the researcher used the modified sex knowledge tools of Kim(l995) and Han(1997). The reliability values of these sex knowledge tools range from 0.71 to 0.74, using Cronbach's alpha. To measure the degree of sex attitude in the subjects, the researcher used the modified sex attitudes tools of Han(l997). The reliability values of these sex attitude tools range from 0.73 to 0.78 using Cronbach's alpha. The PC-SAS package program was used to analyse the data along with Frequency, Percentage, XLtest, t -test, and a paired t -test The results of this study were as follows; 1. The first hypothesis was accepted. The experimental group showed more change in sex - related knowledge than the control group(t =22. 76, p=0.0001). 2. The second hypothesis was accepted. The experimental group showed more change in sex-related attitudes than the control group (t=11.91, p=0.0001). In conclusion, the level of sex-related knowledge and sex-related attitudes of middle school girls who received sex education was higher than that of the girls who did not receive sex education. According to this research, planned sex education was effective in forming accurate knowlege and appropriate attitudes related to sex. Clearly, we must carry out a well-designed step by step sex education program that is well-suited to the sex education needs and the developmental level of the students.

  • The purpose of this study is to provide fundamental information for the development of new sex education image media through the analysis of those tools produced by Planned Parenthood Federation of Korea. Twenty three video tapes related to the sex education were analysed. The data were sampled on the basis of the sex education instructions for primary and secondary schools published by the Seoul Office of Education in 1996 and the list of sex education information composed by the Planned Parenthood Federation of Korea with the following requirements. 1) The education materials are oriented to the middle and high school students as well a juveniles and are being used in public health centers and schools. 2) The education materials are not confined to the single subject such as AIDS or contraception. Because this study is focused on the analysis of image media, an analysis method widely and effectively used in public media study was chosen. The frequency analysis and percentage treatment were done by an SAS program. The results of the study are as follows : 1. An analysis of the material structure type showed that the frequency of the following subjects in 15 video tapes, composed as drama and cartoon, had this decreasing orde : sex behavior, sex relation ships, sex health, human development, personal technique, and society and culture. 2. The eight tapes of explanation and counseling showed a different sequence from that of the drama and cartoon material, primarily treating human development with 5419 seconds (47.9%) of type. The following were also considered in decreasing order: at 2000seconds (17.6%) sex behavior, at 1366 seconds (12.1%) sex health, at 1240 seconds (11.0%) society and culture, at 667 seconds (6.0%) relation ships, and at 611 seconds (5.4%) personal technique. 3. In a thematic analysis those education materials dealing with human development show this frequency sequence: anatomic physiology, reproduction, and adolescence. In relation, ships the sequence is dates, love, marriage and vows, and family. For personal technique, it is expressed as asking for help, and an empnasis on moral values. For sex behavior, they focus on abstinence, the co-responsibility of sex behavior, the sexual response of the human, and sexual nightmares. For the sex health area, the focus is contraception with abortion and reproductive health following that. In society and culture diversity is considered. 4. An analysis of the differences in production and content between 1980s and 1990s was also done. For materials produced in the 1980s the frequency of the subjects follows this order: sex behavior, human development, relation ships, sex health, personal technique, and society and culture with sub subjects such as abstinence, dating, adolescence, anatomic physiology, reproduction, calls for help, and the sexual response of a human being. For materials produced in the 1990s, highest frequency was sex behavior, the same as the 1980s. The rest of the material follows this decreasing order: relationships, human development, sex health, society and culture, and personal technique with sub subjects such as dating, co-resposibility in sex behavior, abstinence, and love frequently considered.
