임신 중 비만은 다양한 합병증을 증가시키고, 출산 시 여러 가지 문제를 유발한다. 그러나 이러한 비만인 산모가 임신중 부정적인 영향을 받는 요인들에 대한 종합적인 분석은 부족한 실정이다. 따라서 본 연구에서는 산모의 신체질량지수를 이용하여 비만 정도에 따른 고위험 질환의 일곱 가지 발생요인들의 영향을 분석하고자 한다. 임신 중 정기검진을 받은 산모 279명을 대상으로 산모의 비만정도를 신체질량지수로 분류하고 산모의 신체질량지수와 임신성 고혈압, 임신성 당뇨, 갑상선자극호르몬과의 유의성을 판단하기 위해 차이분석을 실행하였다. 또한 산모의 나이, 신장기능, 총콜레스테롤, 신생아몸무게와 어떠한 연관성이 있는지 파악하기 위해 회귀분석을 실행하였다. 그 결과, 산모의 비만정도가 높을수록 고혈압 산모, 당뇨산모, 이상갑상선수치를 가진 산모의 비율이 높게 나타났으며 산모의 신체질량지수와 나이, 총콜레스테롤, 신생아몸무게와는 양의 상관관계, 신장기능수치와는 음의 상관관계가 있었다.

The importance of the concept of safety culture has increased in the security of high-risk facility after Chernobyl accident in 1986. This paper elaborated the concept of safety culture and its main factors by Causal Loop Diagram. Due to the decline of safety culture, the occurrence of incidents and accidents require more and more corrective actions to the members of high-risk facilities and thereby increasing their workloads. Employees who must complete the task within the given time have to have time pressures and don't comply with the rules and procedures. Also, a schedule pressure is a big stress for employees, causing mistakes in precision work. In order to improve these problems, CLD of the safety culture in this paper suggests hiring more workers, re-allocation of given workloads and strengthen the learning, communication capabilities and safety leadership. In addition, the two real accident cases were analyzed to test the feasibility of the System Dynamic simulation model through the process of structuring the fault trees on the stationary black out accident in Kori unit 1 in South Korea and Kleen Energy power station explosion in US. The simulation results show that the various safety factors cause the serious accident combined with mechanical failure and safety culture will reduce the possibility of the accidents in these high-risk organizations. This simulation model can contribute to analyzing the impact of the organizational and human factors of safety culture and can provide the alternatives in high-risk facilities.

Purpose: To investigate the degree and sources of stress which fathers of infants in NICU experience. Method: Eighty-five fathers of NICU infants at 5 university hospitals in Seoul volunteered to complete the Parental Stressor Scale for NICU (PSS: NICU) from September 1, to October 15, 2002. Result: Total perceived stress was 3.50±0.76. The highest score were in Parental Role Alteration (3.76±0.83) and Appearance and Behavior (3.65±1.04). The total perceived stress score (PSS), correlated significantly with method (t=3.50, p=.01), and route (F=5.30, p=.00) of feeding. Light & Sound correlated significantly with birth weight (F=3.39, p=.02), medical diagnosis(F=2.30, p=.03), plan of operation(t=2.50, p=.01), operation (t=3.80, p=.02), method (F=4.90, p=.003), and route (F=4.70, p=.00) of feeding. Infant Appearance and Behavior correlated significantly with birth weight (F=5.12, p=.01), plan of operation (t=2.50, p=.01), method (F=3.50, p=.01), and route (F=7.80, p=.00) of feeding. Parental Role Alteration correlated significantly with care of incubator (t=-.68, p=.03), method of feeding (F=2.80, p=.04) and education level of father (F=3.00, p=.05). Conclusion: Father with NICU infants were concerned mostly with parental role alteration and infant appearance. Nursing intervention should include fathers of NICU infants.

Purpose: The purpose of this study was to describe high-risk health behaviors in middle school adolescents and to identify factors related to this behavior. Method: This survey study employed a self administered questionnaire given to 621 students enrolled in one middle school located in Gyeonggi province. Using the cluster sampling method, 4 classes from the 7th, 8th, and 9th grades were selected. The survey was done between April 20 and May 19, 2004. Data were analyzed using SAS. Result: The results showed that 19.1% of adolescents smoked cigarettes and 8.4 % drank regularly. The mean score for resilience was 6.92 (range:0-10) and for depression, 23.62 (range:0-50). The adolescents in higher grades reported significantly more experience with pornography. Also, adolescents who reported have fewer conversations with their parents had significantly more experience with pornography. Depression was significantly higher for those students who had better academic skills and higher family income. Resilience level was significantly higher for the students who reported better schools records and higher family income. The most important factor related to the high risk behaviors, depression, and resilience was conversations with parents. Conclusion: This study suggests that to develop an effective high-risk health behavior prevention program for adolescents, it is necessary to include communication skills with the parents.

Purpose: This study examine the effects of music therapy and phone counseling on postpartum depression and maternal identity in high risk women. Methods: A nonequivalent control group time series research design was employed. Eighteen women comprised the experimental group and seventeen women, the control group. Experimental group received 4 weeks of music therapy and phone counseling. Postpartum depression and maternal identity were measured prior to intervention and on the 1st, 2nd, and 4th weeks after its introduction. Results: The first hypothesis (i.e., "the degree of postpartum depression would be lower in the experimental group than in the control group in a month's time") was not supported (z=-0.47, p=.641). The second hypothesis (i.e., "the degree of maternal identity would be lower in the experimental group than in the control group in a month") was not supported as well (z=1.08, p=.285). Conclusion: There is the need to monitor long-term effects of music therapy and phone counseling on high risk postpartum women, beyond 4 weeks observed in this study. Additionally, the development of music therapy tailored to high risk individuals and systematic phone counseling protocols for postpartum depression is required.

Purpose: The purpose of this study was to identify the effects of a supportive program on uncertainty, anxiety, and maternal-fetal attachment in high-risk pregnant women. Methods: The participants were 59 high-risk pregnant women admitted to the maternal-fetal intensive care unit. The control group (n=30) received usual treatment and antenatal care, while the experimental group (n=29) received an additional supportive program. Uncertainty, anxiety, and maternal-fetal attachment were measured in both groups prior to the intervention and at 3 days and 10 days after the intervention (or at discharge). Data were analyzed with the t-test, chi-square test, repeated-measures analysis of covariance, and the Greenhouse-Geisser correction in SPSS version 23.0. Results: A supportive program including information provision, nutritional care, emotional care, and exercise care was developed from the literature. All variables except women's length of stay were found to be homogeneous the between experimental and control groups in the pre-test. Length of stay was calculated as a covariate for testing hypotheses. There was a significant difference in state anxiety over time between the two groups, while there were no differences in uncertainty or maternal-fetal attachment. Conclusion: This supportive program was identified as an effective nursing intervention on state anxiety in high-risk pregnant women during their stay in the maternal-fetal intensive care unit. It is suggested that nurses could apply this program to alleviate high-risk pregnant women's state anxiety, and that this program could be modified to be more effective on uncertainty and maternal-fetal attachment in high-risk pregnant women.

Objective : High-risk pregnant women are exposed to the physical and emotional crisis associate with the condition of high-risk pregnancy, making these women emotionally unstable, exhibiting such conditions as depression and anxiety. The aim of this study was to examine what effects the temperament and character of high-risk pregnant women had on their depression, anxiety, and maternal-fetal attachment. Methods : A hundred and five high-risk pregnant women were recruited in the maternity ward of the Keimyung University medical center. All subjects were administered a sociodemographic and obstetric questionnaire, Temperament and Character Inventory, Beck Depression Inventory-II, State Trait Anxiety Inventory-State, and Maternal-Fetal Attachment Scale. Results : First, higher scores on the harm-avoidance scale and lower scores on the self-directedness scale were associated with higher depression scores. Second, higher scores on the harm-avoidance and reward-dependence scale were associated with higher anxiety scores. Lastly, higher scores on the cooperativeness scale were associated with higher maternal-fetal attachment scores. Conclusion : Temperament and character in high-risk pregnant women were associated with the degree of depression, anxiety, maternal-fetal attachment. Based on these findings, it is suggested that examining temperament and character in advance and screening for vulnerability in pregnant women can help to prevent emotional problems for high-risk pregnant women.

Purpose: Maternal Fetal Intensive Care Unit (MFICU), which provides intensive care to high-risk mothers with increasing maternal age and high-risk newborns, has become a new field of nursing work in South Korea. The present study was conducted to identify the educational needs and self-assessing clinical competence of nurses in MFICU. Methods: The education needs and competencies of MFICU nurses were measured through prepared questionnaires by researchers based on the previous studies on job analysis of nurses in MFICU. Data were collected from January 2019 to March 2019. The study involved 168 nurses working in MFICUs at 12 hospitals nationwide as study subjects. The data were analyzed using the SPSS WIN 23.0 program. Results: The education needs of nurses in MFICU had an average of 4.21 points (${\pm}0.50$) and their nursing competence was average 3.38 points (${\pm}0.60$). The items reported as high education needs but low competency by nurses in MFICU were as following: 'postpartum hemorrhage and shock,' 'cardiopulmonary resuscitation (CPR) for neonate,' 'CPR during pregnancy,' 'disseminated intravascular coagulation,' 'sepsis,' and 'mechanical ventilation during pregnancy.' Conclusion: Based on these results, it is proposed that a comprehensive education program for nurses in MFICU should be developed by considering low capabilities among MFICU nurses as a priority factor.

Purpose: The incidence of high-risk pregnancies is increasing in Korea as the birth age increases due to late marriage. Maternal-fetal attachment is an important factor that affects children even after childbirth, but it is difficult for high-risk pregnant women to form maternal-fetal attachment. The current study aimed to explore whether taegyo practice (i.e., pregnant women's efforts for fetal good growth and development), self-esteem, and social support influenced the degree of maternal-fetal attachment in women with high-risk pregnancies. Methods: The participants included 226 pregnant Korean women at ≥20 gestational weeks, hospitalized with 15 high-risk pregnancy conditions as defined by the Ministry of Health and Welfare. Recruitment via convenience sampling was done at four sites in Busan, Korea. Surveys were distributed and collected from February 1 to 28, 2022. Data analysis was conducted using descriptive statistics, the t-test, one-factor analysis of variance, Pearson correlation coefficients, and hierarchical multiple regression. Results: On average, participants were 33.97±4.23 years of age and at 31.65±6.23 gestational weeks. Preterm labor (35.4%) and gestational diabetes (21.0%) were the most common high-risk conditions. Maternal-fetal attachment was positively correlated with taegyo practice (r=.70, p<.001), self-esteem (r=.53, p<.001), and social support (r=.53, p<.001), all with statistical significance. Taegyo practice (β=.50, p<.001) and social support (β=.17, p=.030) explained 53% of variance in maternal-fetal attachment in women with high-risk pregnancies. Conclusion: Nurses caring for women with high-risk pregnancies during hospitalization can use these findings by promoting taegyo practice and enhancing social support to increase maternal-fetal attachment.

선박에 적재된 화학물 스타이렌모노머(Styrene Monomer, SM)의 폭발/화재 사고가 울산항에서 발생하여 막대한 손실을 야기하였다. SM은 독성 화학물로서 항해자들이 쉽게 그 위해성을 알 수 없는 문제가 있고, 이러한 SM의 폭발/화재 사고의 원인 규명이 쉽지 않다. 아울러, 최근 들어 SM 이외에 LNG/LPG 등 고위험 화학 화물들의 폭발/화재는 물론 해기사들에게 가해질 수 있는 위해성의 증거가 날로 증가하고 있는 바, 이에 대한 체계적이고 과학적인 연구를 위한 자료의 수집과 분석 및 이를 통한 위해성 연구가 필요하다. 본 연구의 목적은 해기사들에게 SM의 위해성을 교육하기 위한 목적으로 SM의 화학적 반응과 신체 위해성 등을 조사하고, 그에 대한 대응방안을 조사하기 위한 것이다. 장차 해기사로 승선할 학부생의 입장에서 어떠한 위험이 있는지를 인지하는 것은 중요하다. 본 연구는 날로 증가하고 있는 고위험 화학 화물에 대한 경각심 고취와 위해성 이해의 증진에 기여할 것으로 기대된다.
