본 연구는 육묘기 동안 딸기 '매향'(Fragaria ${\times}$ ananassa Duch. cv. Maehyang)의 생육 및 런너 생산과 묘소질에 있어 지베렐린($GA_3$)의 처리방법과 농도에 대한 효과를 평가하기 위해 수행되었다. 딸기 모주는 2018년 3월 20일에 상업적 생육배지로 충진된 포트 ($64{\times}27{\times}18cm$)에 정식하였다. 정식 후 4주째에 $GA_3$의 농도를 0, 50, 100, $200mg{\cdot}L^{-1}$로 식물체당 45mL씩 각각 엽면살포와 배지관주로 처리하였다. 정식 후 배양액의 EC는 $1.5dS{\cdot}m^{-1}$로 공급하였고 뿌리 활착 후 1일 2회 포트 당 350mL(1회당 15분)를 공급했다. 처리 후 7주째에 딸기의 모주의 생육 특성을 측정하였고, 처리 후 10주째에 딸기 자묘의 생육특성을 측정하였다. 모주의 런너 길이와 직경은 $200mg{\cdot}L^{-1}$의 엽면살포에서 다른 처리구에 비해 각각 가장 길고 두꺼웠다. 모주의 SPAD값은 $200mg{\cdot}L^{-1}$의 엽면살포 처리구에서 유의적으로 가장 낮았다. 그러나 엽장, 엽폭, 크라운 직경은 $GA_3$의 처리방법과 농도에 대한 모든 처리구 간의 유의적인 차이를 보이지 않았다. $GA_3$의 농도가 증가할수록 딸기의 크라운이 기형적으로 길어지는 생리장해가 나타났다. $200mg{\cdot}L^{-1}$의 엽면살포 처리에서 유의적으로 많은 생리장해가 나타났으며 배지관주에서는 엽면살포에 비해 적게 나타났다. 런너와 자묘의 수는 처리방법에 무관하게 $GA_3$의 농도가 높아질수록 증가하였다. 자묘의 생육 특성에서, 첫번째 자묘의 엽장과 엽폭, 두 번째 자묘의 초장, 크라운 직경, 엽면적과 SPAD 값, 세 번째 자묘의 초장이 $100mg{\cdot}L^{-1}$의 배지관주에서 유의성 있게 가장 우수하였다. 결과적으로, 딸기 모주의 생육과 런너 생산 및 자묘의 생육은 $GA_3$ $100mg{\cdot}L^{-1}$의 배지관주 처리에서 가장 효과적인 것으로 나타났다.

This study was conducted to analyse the current clinical education of pediatric nursing in baccalaurate nursing program, then to give basic data for enhancing the quality of future clinical education of pediatric nursing. Data were collected through self-reported questionnaire by mail from December 2001 to February 2002. The subjects were 29 schools of 50 baccalaurate nursing education programs. The data were analysed by double raters, researcher and assistant researcher. The results were summarized as follows: 1. Twenty-eight schools had the objectives of the clinical education of pediatric nursing, and 28 schools in pediatric ward, 23 schools in nursery, 22 schools in neonatal intensive care unit(NICU), 15 schools in objectives related to profession by clinical site. 2. Credits on clinical education of pediatric nursing were most 15 schools of 3 credits. 3. The clinical sites were mainly the hospital that sick children were admitted in. 4. The clinical teacher were 9 types including pediatric professor and field nurse. 5. On teacher's role, the professor instructed the case study and conference, and field nurse instructed the patient assignment and nursing procedures. 6. All of schools used explanation and conference as a method of clinical education, 1 or 2 schools used PBL or role play or field study. 7. On clinical education content, most of school included Apgar scoring system, physical examination in newborn assessment, respira- tion maintenance, temperature maintenance, infection prevention, nutrition, and bath in newborn care. 8. On clinical education content, most of school included care of incubator, phototheraty, infusion, gavage feeding and how to use the instruments in NICU. Eighteen schools included attachment promotion, and 20 schools case study. 9. On clinical education content, most of school included a checklist of nursing procedures, case study, assessment of growth and development in pediatric ward and other sites. 10.There were various evaluation types in scores, measuring items. In conclusion, the results of this study revealed that there were some discrepancy in the objectives and contents, clinical sites on hospital focused, teacher's role, and diversity of measurement items and ratings in clinical education of pediatric nursing. There is a need for a standardization of content, clinical site, and evaluation tool to improve a quality of clinical education of pediatric nursing based on this study.

Hearing loss is the most common birth defect among infants. Yet most hearing-impaired children are not identified until 1 to 3 years of age - which is well beyond the critical period(6 month) for healthy speech and language development. However, if a hearing-impairment is identified and treated in its early stages, child's speech and language skills will be comparable to his or her normal- hearing peers. For these reasons, hearing screening at birth and routinely throughout childhood is extremely important. Auditory brain-stem response(ABR) is nowadays one of the most reliable diagnostic tools in the early detection of hard of hearing. In this study, we developed the system that detects auditory evoked potential using micro-processor. Furthermore, it is required to develop a portable system to measure in not only soundproof room but also nursery for infants.

This study analyzes whether children's independent picture book reading affects their reading activities and whether the mother-child interaction during this reading improves their reading activities. The study provides basic data and policy implications for developing children's reading ability. Data were collected from a sample of 192 children aged 4 and 5 in Seoul and Anseong, where a survey of their mothers as well as their nursery school teachers was conducted. Variables of interest were analyzed through a correlation analysis and a hierarchical regression analysis, First, children's reading recognized by their mothers was bipolarized as "very high" or "very low". Second, children's reading activity had a significant positive relationship with independent reading, indicating that children active in independent reading were likely to develop their, reading ability. Third, in addition to independent reading, the mother-child interaction had a significant positive effect on children's-reading ability, indicating the importance of the mother's role in developing the child's reading ability.

Newborn period is a transitional stage for independent adaptation from intrauterine to extrauterine life by maintaining respiration, temperature and nutrition. In general, the adaptability of the newborn is proportional to the gestational age(GA), so knowing the accurate GA is critical to develop nursing process in the newborn nursery. A newborn ma turity rating, a Ballard examination, has been used to measure GA by assessing the maturity of new-born. It consists a total of 12 items, which is the 6 items for the neuromuscular maturity and the 6 items for the physical maturity A total of 75 new-born were assessed for the maturity and GA using the Ballard examination. The results are follows : 1) The score of each item of Ballard examination is propotional to GA using the Ballard examination as well as LMP. 2) There was a greater positive relationship between neuromuscular, physical and total maturity, and the GA measured by Ballard examination, than the GA measured by LMP. 3) Any stressful environment to the newborn could influence to the maturity of newborn. In summary, the study showed the Ballard examination Is more reliable and clincially feasible method to measure the accurate G4 compared to the GA by LMP. Therefore, it suggests the application of Ballard examination to measure the new born maturity and GA is beneficial in developing nursing process. The expansion of the study with the variety of the subject characteristics nil on hance the clinical applicability of the examination.

Purpose: This study was conducted to verify model for predicting health promotion behavior and the health status of child care teachers based on Pender's health promotion model and Dahlgren and Whitehead's health determinants model. Methods: The data was collected from January to February 2018 from 205 child care teachers in day care centers in Seoul. Results: This model was suitable to explain the health status and health promotion behavior of child care teachers. In this study, health promotion behavior had the most direct affect on the health status of child care teachers. Health promotion behavior was directly affected by social support, self-efficacy, and depression. Job stress had an indirect affect on health promotion behavior. Conclusion: Considering the factors identified in this study that influence the health promotion behavior of child care teachers, we propose the development of interventions to improve the health status of child care teachers.

This study was carried out to select the useful plants for the revegetation of flooded slopes in dams, lakes and streams. In this study, four woody plants were investigated for their survival and growth in nursery with various flooding conditions. The results are as follows: Salix gracilistyla showed a very high survival rate and grew continuously under the complete flooding condition. Especially, it grew better under partly flooding condition than non-flooding condition. Amorpha fruticosa showed growth disorder when the flooding period was over 30 days, but the part of stem which was flooded in water adapted itself by branching the adventitious roots. Wisteria floribunda showed respectively high flooding tolerance until 30 days. Lespedeza bicolor were very weak in excessive moisture and flooding conditions. This study confirmed Salix gracilistyla, Amorpha fruticosa and Wisteria floribunda are efficient woody plants for covering the flooded slopes of dam and various impoundment sites.
