  • The purposes of this study were to classify types of consumption values and to examine 5 types of art appreciation of university students in Seoul. Five types of art appreciation included fine art exhibition(including photographs, architects, calligraphy works), classical and opera performance, traditional Korean music performance, drama and musical performance, dance performance. The sample for this study consisted of 422 university students of five universities in Seoul. The data were collected using the structured questionnaires. The statistical methods used for the analysis were descriptive statistics, chi-square, factor analysis, and cluster analysis. The major findings are as follows. 1. The result of factors for consumption values of students emerged four factors. These were called as 'materialism', 'honor centered', 'family centered', 'hedonism' value. 2. The cluster analysis was conducted based on these four factors. The result showed 3 groups of consumption value which were called as 'material' honor value group', 'family value group', 'hedonic value group'. 3. The consumption value of university students did not significantly differ according to their demographic variables. 4. The behavior of art appreciation of university students significantly differed by their demographic characteristics and consumption value. The material' honor valued group showed the least chances to make decisions on art appreciation for one's own, which reflected that this group appreciate art to satisfy their honors rather than to enjoy art itself. They also showed the most chances to consider the renownedness of the art work or artists among three groups. And they showed the least chances to pay for the tickets for art appreciation, all of those meant that they appreciate arts unvoluntarily in situational condition. The family valued group showed the most chances to pay for the tickets when they appreciate arts. And therefore they were most susceptible for the prices. The hedonic valued group showed the most interests in art. They decided to appreciate art for their own, and they considered the contents and the highness in the level of the art the most when they appreciate art. And they show the most intention of participation in drama/musical performances, which reflect their interests in hedonic values. Based on these results of this study concluded that the consumption values of university students affected their behavior of art appreciation. Thus, university students' behavior on art appreciation can be effectively developed by education according to their consumption values.

  • Purpose: This study was conducted in order to prove related practice factors of handwashing with soap and its practices by students in South Korea. Method: The subjects consisted of 700 students. Data were collected in Sep 2013 and were analyzed using descriptive statistics, chi-square test, and logistic regression analysis. Results: Total number of handwashing times was 7.5 per day. 65.1% of the students used soap and most of the students washed their hands for 20 seconds(31.1%). Self-evaluation, awareness of effect for prevention of infectious disease, and need for handwashing education were positive, but evaluation of toilet environment was negative. Most of the students washed their hands for 21 seconds(%), and methods of handwashing were not appropriate. Level of awareness was over 85% in most items. Practice differed significantly according to locations, pattern of school, self-evaluation, awareness of effect for prevention of infectious disease, need for education handwashing, and toilet environment. Conclusion: These findings indicate that the students learned methods of handwashing for its practice in South Korea, and they were considered as general characteristics of handwashing from students. In addition, results mentioned above will be reflected in development of educational programs for improvement of handwashing efficiency.

  • The problems of growth & development due to maladjustment are gradually increasing while need for the treatment of children's diseases is decreasing. The level of developmental deficiency or delay correlates with neonatal birth weight and also with gestational age, i.e. degrees of prematurity. There-fore, developmental defects and potential risk factors' are more Common in premature infants than in full term infants. The purpose of this study is to define the difference in the growth at developmental status between premature and full term infants, and to define the relation between the developmental status and the physical growth during the first 3 years' Data were collected from January 10, 1985 to April 6, 1985 at 3 hospitals including St. Mary's Hospital, and through home visiting. The subjects of this study consisted of 79 Premature infants (G.A. <37wks. & B.W. <2.5kg) and 94 full term infants (G.A.≥37 wks. & B.W.≥2.5kg). The study method used was a questionnaire, anthropometric assessment and DDST for normative data of growth & development. The collected data were analyzed using descriptive statistics, chi-square test and t-test. The results of the study were as follows: Hypothesis: 1 : That the prematures will differ from the full term infants in the physical growth status during the first 3 years was partially supported (p<0.02) : The prematures reached up the full term infants in the physical growth status in the first 6 months. And, the first hypothesis was supported (P<0.01) : There are more cases which is below‘the Korean children's physical. growth standards’in prematures than in full term infants. Hypothesis 2 : That the prematures will differ from the full term infants in the developmental status during the first 3 years was supported (P< 0.001);‘Normal’developmental status due to DDST was less in prematures than in full term infants. And, the second hypothesis was Partially supported (P<0.02) : The developmental status of the pre-matures was different from that of the full term infants within the first 3 months by analysis of passed items in DDST, Hypothesis 3 : That the prematures' developmental status will relate to their physical growth during the first 3 years was supported (P<0.001) : If the prematures' developmental status is in delayed status, then, their physical growth status is also in delayed status. This study shows that the prematures differed significantly from the full term infants in the growth at developmental status during their infancy. This means that the nurse can foster the growth & development of the prematures by supportive care during their infancy. Further longitudinal study is needed to verify these findings for the environmental factors.

  • Background: CYP2E1 encodes an enzyme which is mainly involved in bioactivation of potential carcinogens such as N-nitrosamines. Polymorphisms in the gene have been reported to be associated with cancer. The aim of this study was to evaluate genotype distributions and allele frequencies of five CYP2E1 polymorphisms in Iran Materials and Methods: Two hundred healthy individuals of an Iranian population from the southwest were included in this study. PCR-restriction fragment length polymorphism and Tetra-ARMS PCR methods were applied for CYP2E1 genotyping. Results: The allele frequencies for $^*5B$, $^*6$, $^*7B$, $^*2$, and $^*3$ were calculated to be 1.5%, 16%, 28.5%, 0%, and 2.75% respectively. Results of this study showed that no significant differences in genotype and allele frequencies of five single nucleotide polymorphisms with respect to the gender and tribes. The chi-square test showed that the genotype frequencies of $CYP2E1^*5B$ were similar to Caucasians, but the distribution of $CYP2E1^*6$ genotypes was similar to Asians. The frequencies of $CYP2E1^*2$ (0%) and $CYP2E1^*3$ (2.75%) alleles were within the range for Caucasians and Orientals. In the case of $CYP2E1^*7B$, the data werelimited. Accordingly, the results were only compared with Europeans and the comparison showed significant differences. Conclusions: In conclusion, ethnic and geographic differences may explain discrepancies in the prevalence of CYP2E1 polymorphisms.

  • Parental smoking status and smoking environment do not only affect children's health through exposure to nicotine, but are also related to children's smoking attitude, intention and knowledge of smoking. Since this study was conducted to examine a relationship between family members smoking and smoking attitude, intention and knowledge of their children, little is known about psychosocial factors influencing smoking among Korean preschool children. This study aimed to determine the psychosocial factors (sociodemographic factors, education for smoking cigarette, knowledge about smoke cigarette) influencing smoking attitude and smoking intention, with a purpose of providing directions for future education programs for Korean preschool children. A cross sectional sample of 840 children, ages 4-7 years, living in a rural district were interviewed during August 6 - November 14, 2003. Among them, 834 children whose missing data were less than $10\%$ were included the analysis. The independent variables included sociodemographic characteristics and education for smoking cigarette, while the dependent variables were knowledge about smoking, the children's smoking attitude and their intention of smoking. The data on sociodemographic characteristics were analyzed using descriptive statistics including frequency, percentage, mean, and standard deviation. The correlations between the independent variables and attitude and intention of smoking were analyzed using chi-square test, t-test, and logistic regression. The results of this study were s follows. The factors that were found to be significantly correlated to smoking attitude include mother's smoking $(x^2=4.86,\;p=.03)$, grandmother's smoking $(x^2=5.56,\;p=.02)$, and knowledge of smoking cigarette $(x^2=-5.13 p<.01)$. The factors that were significantly correlated to the intention of smoking include gender $(x^2=.08,\; p=.02)$, education for smoking$(x^2=17.65,\;p<.01)$, mother's smoking $(x^2=19.05,\; p<.01)$, grandmother's smoking $(x^2=17.67,\; p<.01)$, and knowledge$(x^2=-2.17,\;p=.03)$. The children who had non smoking mother were more likely to have negative attitude (OR=2.29). The children who had a higher knowledge about smoking were more likely to have negative attitude (OR=1.58). The findings suggest that a smoking prevention program specific for preschool children is necessary to prevent early onset of smoking. The findings also suggest that the program should involve children's family members who influence their smoking attitude and intention.
