Purpose: This study was to examine how an invasive procedures education program affected the anxiety and supportive behavior of mothers with hospitalized children, and to help provide an efficient to improve their maternal role performance by boosting their supportive behavior. Method: To evaluate their anxiety, Spilberger(1972)'s Anxiety Inventory that was translated by Kim Jeong-taek, et al.(1978) was employed, and Weon Dae-yeoung(1999)'s modified version of Melnyx(1994)'s Index of Parent Support During Instructive Procedure was utilized to assess their supportive behavior. The collected data were analyzed with SPSS program. Statistical data on real number and percentage were acquired, and $x^2$-test and t-test were conducted. Result: There was a more favorable change in the anxiety(trait anxiety and state anxiety) of the experimental group that participated in an invasive procedures education program(a mean of -0.14) than in that of the control group that didn't(a mean of 0.16). The experimental group(an average of 4..65) outstripped the control group(a mean of 3.42) in that regard. Conclusions: The invasive procedures education program that catered to the mothers with hospitalized children turned out to be effective in easing their anxiety and enhancing their supportive behavior.

The c-myc proto-oncogene, one of the immediately earlY genes, is expressed in various mammalian cell types and heavily involved in the regulation of cell proliferation and differentiation. To determine endogeneous expression pattern of c-myc gene in preimpBantation mouse embwos, we employed a reverse transcription coupled to polvrnerase chain reaction (RT-PCR). Transcript of c-myc was detected at fertilized embryos as a maternal transcript. At the early two-cell stave, transcript of c-myc gene was hardly detected, bu, appeared at late two-cell embryos as a zygotic transcript. The level of c-myc expresion was increased at later stases and peaked at blastocvst stage. To examine the functional role of promoter region for c-myc gene transcription, we fused the 5'upstream region (1.8 kb) including econ 1 of c-myc genomic DNA with E. coli lacE gene fnamed as pcMYC-laczl. pcMYC-lacZ was microiniected into the pronscleus of mouse one-cell embryovs, and p·salactosidase activity was determined tv histochemical staining with X-gal at different stases. f-galactosidase activity was detected only at blastocyst, but not at the earlier stage embryos. This result indicates that c-myc gene is transcriptionallv active during mouse preimplantation development.

Purpose: This study was conducted to estimate the prevalence of asthma and its risk factors in childhood asthma. Method: Random samples of 10,236 were selected from 43 kindergarten (1,418) and 57 elementary (8,718) in K city between september and November (2007). 1,079 (kindergarten children) and 7,271 (elementary children) were in the final analysis. The Korean-translated modified version of the questionnaire for the International Study of Asthma and Allergies in Childhood was used in this cross-sectional survey. Parents were surveyed to answer for the questionnaire. Result: The lifetime and 12-month prevalence of wheezing were 11.50%; 11.06% in kindergarten children and 19.24%; 4.80% in elementary children. The lifetime prevalence of asthma diagnosis and the 12-month prevalence of asthma treatment were 11.59%; 4.43% in kindergarten children and 4.43%; 10.78% in elementary children. The 12-month prevalence of night cough and exercise-induced wheezing were 12.90%; 3.33% in kindergarten children and 20.72%; 4.74% in elementary children. Risk factors analysis showed that age, paternal and maternal asthma, allergic disease, carpet use, monthly income, indoor environment were associated with a higher risk of asthma. Conclusion: The study suggests that prevalence of asthma has increased among the community children. These data have been used to manage a possible role of risk factors as predictors of childhood asthma.

Robinia pseudoacacia has become invasively naturalized in Japan. We investigated the role of sexual reproduction in the development of R. pseudoacacia riparian forests along the Chikumagawa River in Japan, by using five chloroplast (cpSSR) and seven nuclear (nSSR) markers. We identified eight chloroplast haplotypes and 147 nuclear genotypes from 619 R. pseudoacacia trees sampled in three plots (Plots A, B, and C) and along two line transects (Lines D and E). CpSSR analyses showed that multiple maternal lines were distributed along the river, and that some haplotypes from different populations overlapped. In addition, while Plots A and B were separated by a short distance, only these two plots exhibited genetic differentiation in the haplotypes. In the nSSR analysis, all pairwise $F_{ST}$ values among the three plots were significantly different from zero. Kinship analysis based on nSSR markers revealed that kinship connected many individuals to another individual from the same plot. These results indicate that seed dispersal near to mother trees contributes to the fine-scale genetic structure of R. pseudoacacia riparian forests. Our results indicate that sexual reproduction, in addition to asexual reproduction, is a major contributor to the fine-scale formation of R. pseudoacacia forests.

This study was carried out to identify and re-establish the professional identity in clinical nurses. Method: From Dec. 1999, for 4 months, the study had been conducted by narrative analysis method based on hermeneutic principles. Subjects were ten nurses with 3-4 years of nursing experience at a university hospital. The data were collected and transcribed through narrative interviews. Result: As a result, the maternal role was identified as the most dominant discourse in which nurses formed their identity. Subjects felt that a maternity is socio-culturally needed in case of nursing. Reconstruction of professional identity consists of 3 stages, Telling, Retelling and Rebuilding. At first, nurses felt confused by skeptism of the profession, interpersonal difficulties, and heavy work loads. However, during the interviews, nurses recognized that nursing is not regarded as significant, effort to make nursing meaningful were small, and there was a lack of understanding others. From this new insight, they re-established a new image of nursing ″through better understanding of others, seeking knowledge, and making positive efforts towards qualified nursing". Conclusion: The above narrative interviews may help nurses reflect and contextually interpret themselves, so that a new identity could be established. Furthermore researchers can obtain new insight from the subjects, while the subjects form a new nursing image from self-reflection.tion.

The Princess Bari, an epic song passed down orally among the korean shamans, describes the process of its heroine's becoming a shaman. The life of a shaman coincides with the image of Mother Goddess that created human beings in that her role was to connect the life here and hereafter in Korea. Princess Bari, an abandoned daughter, experiences the world of death, sacrifices herself completely for her parents, devotes to her husband and gives birth to seven sons. She is a Mother Goddess who embraces fecundity and fertility, creation and destruction, and life and death. Furthermore, she is a "warm-hearted Mother Goddess" who takes the deceased to their last journey with maternal care. The number "seven", known to be a very significant number in human lives and the world after death, symbolizes how princess Bari had to be born as the seventh girl of her parents, not as the fifth or the sixth.

Parental leave in Sweden is a part of the health insurance in national social insurance system. It has two kinds of benefits. One is parental cash benefit paid for both husband and wife on the occasion of child birth, currently 450days for each child. The other is temporary parental cash benefit when a child under the age of twelve or a caretaker for him is illness, which is six months for a child a year. Parental insurance in Sweden permits parents to take care of their children just after birth at home with the amount of 80% of monthly income for 360 days and 60 Swedish krone each day for 90 days more. It also permits parents with children under the age of eight of part-time work and return to former job at full-time base when they want. It consequently encourages women's economic activity in her whole life and contributes to promotion of equality in sex roles between husband and wife. This insurance scheme is beneficient in that it enhances individual and family welfare and also secures labour force. This case study on Swedish parental insurance offers implication how to resolve the conflict between women's increased demand for economic activity and maternal role.

Purpose: This study examined the effects of simulation-based education on knowledge about and self-confidence in maternity nursing care in senior students. Methods: One group, pre-post design, was utilized with 28 students. The simulation-based maternity nursing education that consisted of two sessions each 2 hours long for intrapartum and postpartum care was provided to 4 small groups. An expert panel of 3 maternity clinical instructors developed the module with a high-fidelity maternal simulator. Core items of knowledge about and self-confidence in maternity nursing care were measured with 13 items before and after the sessions. Results: The knowledge score did not increase significantly (z=-1.95, p=.05); however, self-confidence in maternity nursing care showed a significant change in the posttest (z=-2.82, p<.001). The subjective evaluation of the students indicated that the simulation-based education was helpful in preparing for clinical practicum as far as interaction with clients, psychological readiness to practice, and learning efficiencies. Conclusion: The simulation-based nursing education was useful in improving self-confidence in clinical performance for childbirth and postpartum care in nursing students. Along with the application of diverse scenarios in simulations, modules with standard patients and role-plays are also recommended for maternity nursing practicum to empower the competency of the students.

MARCH5 is a RING finger E3 ligase involved in mitochondrial integrity, cellular protein homeostasis, and the regulation of mitochondrial fusion and fission. To determine the function of MARCH5 during development, we assessed transcript expression in zebrafish embryos. We found that march5 transcripts were of maternal origin and evenly distributed at the 1-cell stage, except for the mid-blastula transition, with expression predominantly in the developing central nervous system at later stages of embryogenesis. Overexpression of march5 impaired convergent extension movement during gastrulation, resulting in reduced patterning along the dorsoventral axis and alterations in the ventral cell types. Overexpression and knockdown of march5 disrupted the organization of the developing telencephalon and diencephalon. Lastly, we found that the transcription of march5 was tightly regulated by the transcriptional regulators CHOP, C/EBPα, Staf, Znf143a, and Znf76. These results demonstrate the essential role of March5 in the development of zebrafish embryos.
