The present study investigated the sleep patterns 1-to 3-year-old children and examined whether their sleep patterns would predict their early adjustment to daycare centers. The participants were 239 young children attending daycare centers in Seoul. The data on children's sleep patterns were collected by parent report. Children's adjustment to daycare was assessed by daycare providers' reports. The data were analyzed by means of Chi-square test, t-test, Pearson's correlation, ANOVA and discriminant analysis. The results were as follows: Children from dual-earner families had shorter nocturnal sleep duration than those from single-earner families. There was no significant relation between daytime sleep duration and sleep-onset time at night. It was found that children who go to bed earlier were more likely to get sufficient sleep without nocturnal wakefulness. Age and total sleep duration were seen to be significant variables when it came to discriminating between the adjustment versus maladjustment groups.

The magnetic and transport properties far single crystals of Ru-doped mono-layered manganites $La_{0.5}Sr_{1.5}-Mn_{1-x}Ru_xO_4$ (0$\leq$$\chi$$\leq$0.1) have been studied using neutron diffraction and magnetization measurements. Temperature dependent magnetization data reveal that with an increase in the Ru concentration the parent charge ordered antiferromagnetic state is gradually destroyed and new ferromagnetic phase evolves. In the low Ru-doped system spin glass behavior is apparent in low temperature region, which is confirmed by ac and do magnetization measurements. The competing magnetic interaction between Mn/Mn and Mn/Ru couples is the most likely cause of the spin glass transition.

Recent demographic changes have increased the heterogeneity of user groups in the housing market. Smaller households(e.g. elderly, single parent) have non-traditional spatial requirements that cannot be accommodated within the conventional house layout. This has created renewed interest in Demountable/Flexible housing systems. However, the process by which designers decide which project or user groups are most suited for the use of these systems is quite often complex, uncertain and dynamic, since the decisions involve natural processes and human values that are apparently random. This study is a proposal on the design process model for the flexibility of apartment.

Development of oidia, a type of thallic spores from monokaryotic mycelium of Coprinus cinereus was examined with electron microscope and light microscopes. Oidia formation in this fungus is unique in its mode of formation compared with other types of asexual sporogenesis. Oidiogenesis in C. cinereus is carried out in three steps: 1) Formation of oidiophore from the parent mycelium, 2) Formation of initials of oidial cells from swollen oidiophore, 3) Segmentation and detachment of mature oidial cell. Oidiophores appear to spring out singly as a swollen hyphal branches from the normal foot hyphae or sometimes coiled hypha. From the oidiophore, oidial branches sprout out forming a group of $2{\sim}6$, most often 4 oidial cells and each oidial cell undergoes a single mitosis resulting in 2 oidia. One of the sibling oidial cells in a group is frequently transformed into a new oidiophore, thus oidiogenic structures are tandemly produced at the several different levels.

Purpose: The Purpose of this study was to analyze the trend of research related with unmarried mother. Method: 81 theses about unmarried mother from 1972 to 2003 were analyzed according to the theses' characteristics, sources by publication period, research design, nursing intervention effect of experimental study and theme of qualitative research. Results: 1. The number of studies related with unmarried mother has progressively increased by year from 1972, and that of theses was highest during the period between 2000 to 2003. 2 As for study design, the number of quantitative studies were 73 and that of qualitative studies were 8. The majority of research design were survey and correlational studies. 3. Nursing intervention used in the experimental design were stress management program, eco-system support group, group art treatment, career education program, musical activities, prenatal education. All of experimental design were used in the after 2000. 4. The themes of qualitative studies were childbirth experience, a participatory on the life, mother's keeping a child, experience of pregnancy and delivery, the self-group program, the process and experience of becoming unmarried adolescent mother, needs of single mothers with child and policy of social welfare service, lived experience of hope. All of these were used in the after 1999. Conclusions: The summary of the above results shows a tendency that the study has increased by year. Especially, experimental study proved affirmative effect. However, for the unmarried mother, more experimental and qualitative studies are to be required.

Objectives: The Child Report of Post-traumatic Symptoms (CROPS) and the Parent Report of Post-traumatic Symptoms (PROPS) are screening measures for post-traumatic symptoms in children. The present study aimed to investigate the reliability and validity of the Korean versions of the CROPS and the PROPS. Methods: The Korean versions of the CROPS and the PROPS were administered to a sample of 304 children aged 6 to 15 years old. The internal reliability, test-retest reliability, factorial validity, predictive validity and concurrent validity were evaluated. Results: The reliability of the CROPS and the PROPS was shown to have excellent internal consistency and test-retest correlation. The single factor structure of the PROPS was good and that of the CROPS was borderline acceptable according to confirmatory factor analysis. Other validity measures such as the predictive validity and concurrent validity were also shown to be satisfactory. Conclusion: This study demonstrated that the Korean versions of the CROPS and the PROPS were reliable measures with satisfactory psychometric qualities. Because it takes less than 5 minutes to fill out the CROPS and the PROPS, respectively they can be quick and easy screening scales for assessing post-traumatic symptoms in Korean children.

Purpose: This study was a part of preliminary survey for establishing Korean HPS(Health Promoting School) model which was originally suggested by WHO. Methods: Three elementary and middle schools were sampled in urban and rural area across three level of social-economic status, and survey was conducted on one class in each grade by random selection. To measure mental health and social and familial factors, self-esteem scale, self-efficacy scale, depression scale, family cohesion scale, parent-child communication scale, adolescent's mental health and problem behavior questionnaire(AMPQ), and other question items about family status and economic level were conducted. Students' mental health level was compared by region, sex, grade, and other familial and economic factors. Results: Familial and social factors such as economical and educational level of parents, number of family members were different between rural and urban area. Also, students of rural area got lower scores at self-esteem, self-efficacy, but higher scores at extroverted problem behavior than their urban counterparts. In pre-school students, high grade students' self-esteem, and family cohesion scores were lower than low grade students. And sexual differences were found across problem behavior domain and region in middle school students. Especially, the students of single-parent family and lower economic family got insistently low scores at various mental health related scales. Conclusion: These results should be considered, when the HPS model is designed and applied in Korea.

An attenuated vaccine strain AVR1/08 of Korean respiratory type of infectious bronchitis virus (IBV) was developed by 89th passages of IBV D85/06 strain in chicken eggs. The AVR1/08 strain had higher virus titer at least 20 times ($10^{1.3}$) than the parent virus D85/06 by egg inoculation method. The AVR1/08 strain had a single point mutation (S to Y) at position 56 of spike protein of IBV compared to parent virus IBV D85/06 strain. The mutation was observed consistently at viruses after 47th passage in chicken eggs. The AVR1/08 strain showed no virulence even after 6 passages in chickens and all chickens inoculated induced anti-IBV antibody 14 days after vaccination. The AVR1/08 strain had broad protective efficacy against QX type Korean nephropathogenic virus (Q43/06 strain), KM91 type Korean nephropathogenic virus (KM91 strain) and Korean respiratory virus (D85/06 strain). In contrast, Massachusetts (Mass) type attenuated vaccine strain H120 showed protection of 37.5 to 50% against these three viruses. Our results indicate that the AVR1/08 strain has potential as an attenuated vaccine effective in controlling IBVs circulating in Korea.
