The purpose of this study was to analyze the differences in the expenses of private education and the economic preparations for old age according to household income and consumption wants for education in mothers with school-aged children. The data used in this study were collected from 416 mothers with school-aged children aged 8 to 19 years old living in Daegu. The data analysis methods adopted for the study were two-way ANOVA and Scheff$\acute{e}$ test. The results of this study were as follows: First, there were differences in the private education expenditure according to the household income and the consumption wants for education in mothers with school-aged children. In the group of mothers of low household income, the mothers with high consumption wants for education spent more money on academic education and music, fine arts or physical education than the mother's with low consumption wants for education. On the other hand, in the group of mothers of high household income, the mothers with low consumption wants for education spent more money on academic education and spent less money on music, fine arts or physical education than the mothers with high consumption wants for education. There were no meaningful differences in the group of mothers of middle household income. Second, there were differences in the perceived burden of private education expenditure according to the household income and the consumption wants for education in mothers with school-aged children. In the group of mothers of middle household income, the mothers with low consumption wants for education perceived there was a higher burden for private education expenditure than the mothers with high consumption wants for education. Third, there were differences in the expenditure preparation for old age and the economic preparation behavior for old age according to the level of household income. The mothers with high household income spent more money on preparation for old age and did well in economic preparation behavior for old age than the mothers with middle and low household income.

The reason that aromatherapy began to draw attention again as the alternative therapy is because the essential oils that are used for aromatherapy not only allow the human body to maintain homeostasis but also have an effect on curing a mental feeling of fatigue and because these efficacies and effects are proceeding with being proved scientifically. Also, with coming to be high in a voice of concern about severally side effects that the modern medicine and the synthetic chemistry have, the aromatherapy came to be paid attention as the replacement therapy that can substitute for and supplement this. In particular, at the time of requiring a study on a substance to substitute for this after having been announced in Japan for 1998 a risk of Zincpyrithione that is being used as a component of dandruff treatment, it is thought that the aroma oil that was known for having an anti-dandruff effect has a merit of being easy in a user's access, thus it will be effective in curing the symptom of dandruff. Accordingly, this study conducted the following experiment in a bid to examine whether the aroma oil has the anti-microbial effect on the actual malassezia. First of all, it measured the minimum concentration of aroma oil in which the growth of malassezia is inhibited, by carrying out MIC(Minimum Inhibition Concentration) test in terms of anti-microbial activity against Malassezia furfur KCTC 7744 while using oils of Patchouli, Rosemary, Lavender, and Tea tree among aroma oils that are being used for dandruff treatment. As a result of that, Tea tree oil has the most excellent anti-microbial activity, and the measurement result of anti-microbial activity was shown in order of Lavender oil>Rosemary oil>Patchouli oil. Next, it carried out the is actually eased by applying Tea tree oil directly to the scalp of dandruff. In consequence of the experiment, the massage of Tea tree oil indicated the result of relieving the symptoms of dandruff such as scale, itch, pain, inflammation, and sebum, and among these symptoms of dandruff, it was shown to be most effective in easing itch. Especially, this clinical experiment was indicated that the massage of Tea tree oil has the most effect on relieving itch of targets with a dry-skin type who had no experience of dandruff treatment.

This study was conducted to investigate the dietary habits and nutritional knowledge of 5th and 6th graders and the teachers' perception of dietary life education at the elementary schools in Chuncheon area. The children who had breakfast and supper everyday accounted for 54.1% and 80.3% each. Children consumed 'breads or confectioneries'(42.6%) and 'fruits or juices'(39.3) as snacks. Only 57.4% of the children had balanced diet. Only 59% of the children answered correctly at the nutritional knowledge test, and only 75% had good dietary behaviors. About 78% of the teachers had the experiences of dietary life education, and they taught it in class(38.9%) or at school lunchtime(35.2%). The teachers answered that the major nutrition problems of elementary students were bad eating habits(37.7%) and too much ingestion of fast or instant foods(36.2%). They also answered that dietary life education was necessary(79.7%) and should be started more earlier(87.0%). Ironically, about 49% of the teachers answered that dietary life education should be taught by dietitians even if the teacher who spent most of the time with their students is the best person for dietary life education at school. It should be done in children's daily life, especially for elementary school students. Therefore, teachers should recognize the importance and the specialty of dietary life education at the elementary schools.

The purpose of this study are 1. Evaluate the degree of knowledge of Vaginal Birth After Cesarean(VBAC) of Korean nurses. 2. To gather and develop educational material for VBAC. The sample was surveyed Korean Nurses knowledge about VBAC, from November 1998 through March 1999. For the data analysis, the SPSS computer program percentage and frequency were used for descriptive statistics. The x2 and the t-test were used to compare the results of the two sample groups. Open questions asked in the survey were sorted out by content, then displayed in chart form. For the education material, the Internet was the main source of information. Information on the Internet was provided by professional doctors and prenatal educational nurses. The results of the survey are as follows: 1. Out of 97 Nurses 15.3% answered that cesarean deliveries do not need to be performed after previous cesarean sections : however. 46.4% answered that cesarean sections must be performed after previous cesarean sections. 2. Of the nurses surveyed 14% had no knowledge or had never heard of VBAC. 3 Nurses did not have questions from patients concerning VBAC was 34.7%. This led to the conclusion that patients either do not have knowledge about VBAC or patients have no interest in the trial of labor. 4, Nurses indicated that their information about VBAC originated from other people's experiences (31%), Nursing School (25%), Media information (9%), and through literature review (6%). This data led to the conclusion that the knowledge about VBAC may not be extensive enough to counsel and guide patients who are willing to endure the trial of labor. 5. Nurses preferred hospital education programs to develop their knowledge concerning VBAC. Based upon survey, the conclusion was made that General Nurses and Maternity Nurses did not have knowledge about VBAC success rates and the possibility of a trial of labor. In order for nurses to help patients make decisions concerning VBAC, nurses have to gam more knowledge through hospital educational programs. Further more, the study suggests that through hospital educational programs, the possibility and importance of VBAC must be emphasized to nurses who work in maternity areas. Second, through prenatal educational programs, the possibility and importance of VBAC must be explained and emphasized to patients who had previous cesarean sections. Third, the clinical pathways of VBAC need to be developed. Fourth, each hospital needs to develop multi-disciplinary teams, consis-ting of obstetricians, risk management/quality management, staff registered nurses, and the director for perinatal services. This team can review cesarean section rates and help to increase the practice of VBAC.

Many studies have reported that regular aquatic exercise can lead to improvement of health for patients suffering from arthritis. In spite of these benefits, the adherence rate has shown as few as 26% of patients with arthritis who had completed the aquatic exercise education program. Moreover, when patients with arthritis begin an aquatic exercise, 47% withdraw within the first 6 month. No study has been found that constructs model to explain aquatic exercise adherence of patients with arthritis. The purpose of this study were to identify the factors influencing exercise adherence and to construct and test a structural model to explain aquatic exercise adherence of patients with arthritis. Hypothesized model was constructed on the basis of Bandura's social cognitive theory and literature review. Exogenous latent variables included in this model are group cohesion and barrier, endogenous latent variables are self-efficacy, outcome expectancy and self-evaluation. Empirical data used was collected through individual interviews with the structural questionnaire on 249 patients with arthritis who had completed the 6-week aquatic exercise education program of Korean Rheumatology Health Professionals Academy. The interviews were performed from September 6, 1999 through October 8, 1999. A model tested by the covariance structural analysis with LISREL 8.12a program and by descriptive statistics and correlation with SAS 6.12 program. The results are summarized as follows: First, hypothesized model showed a good fit to the empirical data. In the modified model added one new path showed a much better fit. Second, group cohesion had a direct, indirect positive effects, self-efficacy and self evaluation had a direct positive effects on exercise adherence. Barrier had a direct, indirect negative effects on exercise adherence. Outcome expectancy had a direct negative effect, indirect positive effects through self-evaluation on exercise adherence, but total effects was not significant. Total effect size of the variables were group cohesion, self-efficacy, barrier and self evaluation in order. All variables accounted for 54% of the total variance of exercise adherence in the model. In conclusion, this model confirmed to be proper in explaining of aquatic exercise adherence. Group cohesion, self-efficacy, outcome expectancy, self-evaluation, barrier contributed to the aquatic exercise adherence of patients with arthritis. The results of this study suggested that improvement of group cohesion, self-efficacy and self-evaluation, motivation of outcome expectancy through self-evaluation, and reduction of the barrier should be included in the strategy of nursing intervention for the aquatic exercise adherence of patients with arthritis.

This study was undertaken to identify the levels and affecting factors of the maternal role attainment(MRA) in the primipara during the postpartum period. The healthy ninety primiparous from the one university hospital and two local clinics in KwangJu city were selected and two Semantic Differential Scales (SD-Myself as Mothers, SD-My Baby) and the Pharis Self Confidence Scale were used in this study. Questionnaires were distributed at the 3rd days and the 4-6 weeks of the primiparous not showing any complication after normal delivery. The data collected were analysed statistically using t-test, Pearson's Product Moment Correlation Coefficient and ANOVA. The results obtained were summarized as follows; 1) On the 3rd day after the delivery, the scores of SD-myself as mother, SD-baby and Pharis Self Confidence were 70.6 points, 73.6 points and 78.6 points, respectively, showing the low level of MRA. 2) On the 4-6 weeks after delivery, the score of SD-myself as mother, SD-baby and Pharis Self Confidence were 72.8 points, 77.9 points, and 86.9 points, respectively, indicating the moderate level of MRA. 3) The mean scores of the SD scale and the Pharis Self Confidence during the postpartum periods were higher than those of the 3rd days, showing the SD-myself as mother (t=-2.09, P<.05), SD-baby(t=-4.12, P<.001), Pharis Self Confidence(t=-6.59, P<.001), respectively. 4) Positive correlations (r=.24$\sim$.69) were shown in the concepts related to the MRA and the cognitive-motor skill components and cognitive-affective skill components of the MRA became harmonious over time. 5) The relationships between the score of the MRA and the demographic and obstetric variables were as follows ; a) the score of the MRA in the twenties was higher than those of the thirties. b) the group with higher educational background showed higher MRA socres than the group with lower one. c) those who wanted pregnancy sustenance had higher MRA scores than those who did not. d) the group that did think of festus-feature represented higher MRA scores than those who did not. e) the group of mothers who have the daughters showed higher MRA scores than those who have boys. It can be concluded from the results that the MRA in the primiparous increased gradually, and that the cognitive-motor skills and cognitive-affective skills became harmonious over time. The level of the MRA was affected partly by the mothers general, obstetrical variables. Following suggestion were made oil the basis of the present study ; a) The longitudinal study on the MRA is needed. b) Multivariate analyses should be done for the identification of the factors influcening on the MRA. c) Education program for primiparous mother should be designed and developed to improve the MRA.

In this paper, an active object tracking system basing on the pan/tilt-embedded stereo camera system is suggested and implemented. In the proposed system, once the face area of a target is detected from the input stereo image by using a YCbCr color model and phase-type correlation scheme and then, using this data as well as the geometric information of the tracking system, the distance and 3D information of the target are effectively extracted in real-time. Basing on these extracted data the pan/tilted-embedded stereo camera system is adaptively controlled and as a result, the proposed system can track the target adaptively under the various circumstance of the target. From some experiments using 480 frames of the test input stereo image, it is analyzed that a standard variation between the measured and computed the estimated target's height and an error ratio between the measured and computed 3D coordinate values of the target is also kept to be very low value of 1.03 and 1.18% on average, respectively. From these good experimental results a possibility of implementing a new real-time intelligent stereo target tracking and surveillance system using the proposed scheme is finally suggested.

This study aimed to identify the convergence relationships among nutrition knowledge, health beliefs, diet self-efficacy, and diet management behaviors among Sri Lankans with hypertension (HTN). 91 adults diagnosed with HTN for more than one year participated in this study. A set of interviewer-administered questionnaire was used to assess general characteristics, nutrition knowledge, health beliefs, diet self-efficacy, and diet management behaviors. A stepwise multiple regression analysis was conducted to identify the factors that might influence diet management behaviors. There were statistically significant positive correlations between nutrition knowledge (r=0.26, p=.013), health beliefs (r=0.35, p=.001), diet self-efficacy (r=0.34, p=.001) and HTN diet management behaviors. Three variables, nutrition knowledge, health beliefs, and diet self-efficacy, explained 19.9% of the variance in HTN diet management behaviors (F=8.36, p=.001). Diet self-efficacy was the most significant influencing factor (${\beta}=.29$, t=2.75, p=.007), followed by nutrition knowledge (${\beta}=.25$, t=2.50, p=.014). The findings of this study can be used as valuable data for developing effective interventions to improve diet management behaviors of persons with HTN.

Herein, life time prediction based on the deterioration of physical properties of chloroprene rubber (CR)aged by heat and seawater was performed. CR samples were experienced an accelerated test at $80^{\circ}C$, $100^{\circ}C$, $120^{\circ}C$ for heat aging, and $40^{\circ}C$, $60^{\circ}C$, $80^{\circ}C$ for seawater aging for 20,000 hrs. The change in tensile strength, maximum elongation,hardness was measured. As a result, the decrease in elongation was a major factor causing failure. The life time estimated using an Arrhenius model was 125 years at $23^{\circ}C$ for thermal aging and 9 years at $23^{\circ}C$ for seawater aging. SEM and elemental analysis reveal that cracks were generated and the content of oxygen was increased for CR agined by seawater. FT-IR spectrum shows the new C-O and C = O bonds were generated by the chemical reaction with seawater. Also, the glass transtion temperature was increased and the thermal decomposition was decreased by seawater aging.
