목 적 : 본원에서 출생한 미숙아들을 대상으로 하여 이들 미숙아들 중에서 부당 경량아 출생과 관련이 있는 요인들에 대해 알아보고자 본 연구를 시행하였다. 방 법 : 2000년 1월부터 2006년 8월까지 출생한 재태 연령 26주 이상 35주 이하의 미숙아 1,010명을 대상으로 하였으며 이들과 이들의 모체의 의무기록을 후향적으로 조사하여 재태 연령, 출생 체중, 성별, 출생 순위, 산모의 나이 및 이전 유산 횟수 등에 관한 자료들을 수집하였고 부당 경량아 출생과 관련이 있는 요인들을 비교 분석하였다. 결 과 : 본 연구에서 미숙아들 중에서 여아에서 남아보다 부당 경량아 출생이 더 많은 것으로 나타났으며(P=0.042) 또한 산모의 나이가 20세 미만이거나 35세 이상인 경우에 부당 경량아 출생이 더 많은 것으로 나타났다(P=0.041). 미숙아의 출생 순위나 산모의 이전 유산 경력은 부당 경량아 출생과 통계학적인 관련성이 없는 것으로 나타났다(P=0.228, P=0.129). 결 론 : 출생 체중과 미숙아의 생존율과의 관련성을 생각해 보면 산모의 나이가 미숙아의 생존율과 관련이 있는 것으로 생각된다. 10대 임신을 줄이고 산모가 고령이 되기 전에 출산을 할 수 있도록 여러 사회적, 정책적인 뒷받침이 이루어진다면 미숙아들의 생존율을 높이고 더 나아가 건강한 정상 신생아 분만에도 큰 도움이 되리라 생각된다.

Purpose. The purpose of this study was to evaluate the premature infants' responses to infant massage (tactile and kinesthetic stimulation). These responses measured by weight, physiological (vagal tone, heart rate, oxygen saturation) and behavioral responses (behavioral states, motor activities, and behavioral distress). Methods. This study was conducted using an equivalent control pretest-posttest design. The sample was divided into two groups of 13 infants with gestational age less than 36 weeks at birth, birth weight less than 2000g, and no congenital anomalies. The experimental group received the massage intervention twice daily for 10 days. The data were collected for 10 minutes prior to and 10 minutes after the massage. Results. The vagal tone was significantly higher after massage than before massage in the experimental group, while no change in the control group. The experimental group had significantly higher scores for awake state and motor activity than the control group. Significantly greater awake state, more fidgeting or crying, and increased motor activity were reported after massage than before massage. Conclusions. The results of this study showed that massage therapy might enhance optimal physiological responses and behavioral organization of premature infants. Nursing staff in the NICU can use massage to promote the infant's capability to respond positively to his environment and to provide developmental support for healthy premature infants.

Purpose: This research was conducted to evaluate the effects of asystemic follow-up care program on health promotion and risk reduction in 64 high-risk infants(HRI) including premature infants and their mothers. Method: The intervention consisted of systemic NICU education, tele-counseling and 3 home visits in 6 months. The subjects were divided into either the intervention group or the control group receiving the conventional NICU education without the tele-counseling and home visiting. Infant health promotion was measured using physical assessment, types of health problems, reflexes, OPD visiting history, DDST, immunization, feeding assessment, Infant death rate, etc. Maternal self-esteem, postpartum depression and family function were measured using the maternal self-report inventory(MRI), EPDS, and family apgar score(Fapgar), retrospectively. Result: All premature infants in the intervention group were in the normal range of growth and development, and the regular vaccination schedule. The health problems in the intervention group were addressed early so not to develop into adverse effects. The follow-up program for 6 months showed beneficial effects on MRI, EPDS, and Fapgar. Conclusion: A systemic follow-up health care program is beneficial on health promotion and risk reduction in 64 HRI including premature infants and their mothers.

Purpose: This study is a systematic literature review and meta-analysis study conducted to identify the effects of breastfeeding intervention program on premature infants by integrating and analyzing the results of randomized controlled trials and non-randomized trials. Methods: The literature review process was based on the PRISMA (Preference Reporting Items for Systematic Reviews and Meta-Analyzes) guideline. Data retrieval and collection were conducted from May 25 to May 30, 2018, and the articles analyzed were all domestic papers retrieved from the database. Two reviewers independently select the studies and assessed methodological risk of bias of studies using the Cochrane criteria. The topics of breastfeeding interventions were analyzed using descriptive analysis and the effects of intervention were meta-analyzed using the R program. Results: Finally, eight papers were included in the systematic review and meta-analysis. The breastfeeding intervention program for premature infants showed a significant increase in the self-efficacy and the amount of pumping and baby's hight. Conclusion: This study has some limitations due to the few randomized controlled trials and non-randomized trials comparing breastfeeding for premature babies in Korea. Therefore, it needs to be integrated with the research conducted in other countries.

Purpose: The purpose of this study was to examine the effect of a discharge education program on maternal role confidence and parenting stress of mothers who delivered premature infants. The program provided them with information on childrearing and supportive educational nursing care. Method: This study was based on pretest-posttest nonequivalent nonsynchronized quasi-experimental design. The participants in this study were 30 mothers who delivered premature infants at a general hospital in G city. The instruments used in this study were Maternity Confidence Inventory, Parenting Stress Index(PSI). Results: The first hypothesis that the mothers in the experimental group would undergo changes in maternal role confidence after the intervention was accepted, as there was a statistically significant gap between the two groups(F=9.386, P=.000). The second hypothesis that mothers in the experimental group would undergo change in parenting stress after the intervention was accepted, as there was a statistically significant gap between the two groups(F=4.425, P=.380). Conclusion: The findings suggest that the Discharge Education Program was an efficient intervention method to boost the maternal confidence of mothers with premature infants and to decrease their parenting stress.

Purpose: To investigate the effect of nonnutritive sucking(NNS) on the heart rate, oxygen saturation, and behavioral state of premature infants. Method: From December 15, 2004 to February 15, 2005, 20 premature infants hospitalized in the neonatal intensive care units were assigned to an experimental group (10), or a control group (10). Circular pacifiers for premature infants (Johnson, U.S.A.), which had been packed with $2{\times}2$ gauzes to create a vacuum, were used for 5 minutes, one hour after feeding for 5 days. Heart rates and oxygen saturation were checked every minute for 10 minutes once a day and behavioral states were monitored through video recording at the same time. Results: Changes in heart rate, oxygen saturation and behavioral state were found to show significant differences between the experimental group and the control group according to the point in time, and interactions were found between the group and the point of time. However, for behavioral state, no significant difference was found between the experimental group and the control group after the NNS was removed. Conclusion: From the results of this study it is possible to conclude that NNS is a positive intervention to bring about increased oxygen saturation and soothed behavioral state for premature infants.

Arrhythmia has recently emerged as one of the major causes of death in Koreans. Premature Ventricular Contraction (PVC) is the most common arrhythmia that can be found in clinical practice, and it may be a precursor to dangerous arrhythmias, such as paroxysmal insomnia, ventricular fibrillation, and coronary artery disease. Therefore, we need for a method that can detect an abnormal heart beat and diagnose arrhythmia early. We extracted the features corresponding to the QRS pattern from the subject's ECG signal and classify the premature ventricular contraction waveform using the features. We modified the weighting and bias values based on the error back-propagation algorithm through learning data. We classify the normal signal and the premature ventricular contraction signal through the modified weights and deflection values. MIT-BIH arrhythmia data sets were used for performance tests. We used RR interval, QS interval, QR amplitude and RS amplitude features. And the hidden layer with two nodes is composed of two layers to form a total three layers (input layer 0, output layer 3).

Purpose: This study aimed to develop a breast feeding program for mothers of premature infants. The program was applied and its effect was evaluated on stress, knowledge and breastfeeding behaviors of premature infant mothers. Method: This study employed a one group pre- and post-test quasi-experimental design. The data were collected from 17 participants from August 15 to October 24, 2004, at a N1CU at D University Medical Center located in Susan, Korea. Data were analyzed by means of frequency, SD, and t-test using SPSS version 10. Result: After the program, participants significantly showed a greater level of knowledge than before the program (t=-5.750, p=.000). No statistically significant differences in stress level scores were found (t=1.453, p=.153). The breastfeeding practice rate was 94.1%: Conclusion: This educational program using a handbook and video had a positive effect on increasing knowledge and practice of breastfeeding among premature infant mothers. It is suggested that this study be replicated with a larger sample size to compare group responses.

Prematurity is the main cause for respiratory distress syndrome (RDS) in neonates. The goal in the treatment of RDS is to maintain respiration with adequate oxygenation. ETS needs to be performed to remove lung secretions in the ventilated premature infants with RDS. Oxygen saturation(SpO$_2$) and heart rate(HR) were compared in 22 premature infants with RDS using two types of ETS : open ETS versus close ETS. The results showed there was no significant difference in the SpO$_2$ and HR responses between open ETS and close ETS. The SpO$_2$ and HR returned to the baseline within 1 minute after suctioning. But in some case, there was a significantly greater incidence in the decrease of SpO$_2$ below 90% occured in the open ETS than in the close ETS. It implies that closed ETS may be beneficial to the premature infants who tend to develop desaturation easily.
