Purpose: This study was conducted to evaluate the efficacy of a community-based follow-up program on parenting stress, parenting efficacy, and coping among parents with premature infants. Methods: A non-equivalent control group pre-post quasi-experimental design was used. This program consisted of structured home visits and self-help group meetings for 6 months. The experimental group (n=29) received visits by an experienced neonatal intensive care unit (NICU) nurse and the control group (n=27) was visited by a visiting nurse. Data were analyzed using the χ² test, t-test, and analysis of covariance. Results: Parents' coping behavior significantly differed in the experimental group compared to the control group (t=3.14, p=.003). In particular, coping subscale I, for maintaining the family situation (t=2.63, p=.011), and subscale III, for understanding the infant's medical situation (t=4.30, p<.001), showed significant differences in the experimental group. There were no significant between-group differences in parenting stress or parenting efficacy. Conclusion: The findings of this study suggest that home visits by an experienced NICU nurse provided through a community-based follow-up program were an effective intervention to improve coping behavior among parents with premature infants.

It was only 2010 when start-up education spread to undergraduate education in South Korea. Start-up education was conducted so late that there are insufficient studies of evaluation and feedback on the effectiveness of start-up education. Education is a complex concept of teaching people in a desirable direction and developing their inherent abilities. Based on this, start-up education can be defined as cultivating students' entrepreneurial spirit internally and making them exhibit start-up competence externally by teaching them the knowledge, skills and attitudes necessary for business start-up and developing abilities such as creativity, challenge spirit and problem-solving skills. This study conducted pre and post survey to check if the education camp for the technology start-up, which is a practice-oriented start-up education, has an effect on the change of the participating students' perceptions about the business start-up. This study would analyze various factors of college students' business start-up through a factorial analysis so that the quantitative accumulation of start-up education can lead to a qualitative change and propose measures for the management of the quality of the education.

Quantitative analysis was performed to confirm that moire artifact was removed without loss of image when using grid suppression software in the diagnosis of micro lesions. we showed that grid suppression images can be morphologically different from original images as they are significantly lower than those of the optimized grid in the similarity analysis with reference images in mammographic phantom images. We were confirmed that images of microcalcification with smaller signal than noise were lost because the pixel values of all lesions increased significantly after the grid suppression, The change in contrast using the NORMI 13 X-ray test phantom was reduced to 30% of the reference image, This result was significantly lower than the 90% when using the optimized grid. In conclusion, the use of grid suppression software in clinical images should be carefully considered because of the possibility of misdiagnosis due to micro lesion loss and morphological changes.

Transgenic Alstroemeria plants resistant to Alstroemeria mosaic virus (AlMV) were generated through RNA-mediated resistance. To this end, the friable embryogenic callus (FEC) of Alstroemeria was induced from the leaf axil tissue and transformed with a DNA fragment containing the coat protein gene and 3'-nontranslated region of AlMV through an improved particle bombardment system. The bar gene was used as a selection marker. More than 300 independent transgenic FEC lines were obtained. Among these, 155 lines resistant to phosphinothricin (PPT) were selected under low stringent conditions. After increasing the stringency of PPT selection, 44 transgenic lines remained, and 710 somatic embryos from these lines germinated and developed into shoots. These transgenic shoots were then transferred to the greenhouse and challenged with AlMV. In total, 25 of the 44 lines showed some degree of resistance. PCR analysis confirmed the presence of the viral sequence. Virus resistance was observed at various levels. Establishment of an efficient transformation system for Alstroemeria will allow inserting transgenes into this plant to confer resistance to viral and fungal pathogens. Accordingly, this is the first report on the production of a transgenic virus-resistant Alstroemeria and lays the foundation for alternative management of viral diseases in this plant.

In this paper, to analyze the meaning of middle-aged men's economic activities, TEXTOM was used to analyze them. The data collection period is set from 2017 to 2019. Among the collected data, 100 refined words were converted into a matrix in which the degree of social connection was calculated, and the keyword network analysis was performed again with the NetDraw program. According to the study, middle-aged men put more meaning on their current work and family than their future retirement. Also, the related word commonly included in the top five for all three years was 'work'. Related words commonly included in the top 10 were 'old age', 'family', and 'work', and in 2018 and 2019, 'health' was included in the top 10. As a result of this, the middle-aged men living in the modern age are the generation who keep their families through economic activities and are increasingly interested in health and prepare for retirement. Therefore, policy support for stable economic activities is needed to improve the quality of life for middle-aged men. It is necessary to extend the retirement age, expand jobs and provide effective vocational training so that it can handle its role as the head of a family. In addition, measures should be taken to reduce the wage gap between highly skilled and low-skilled workers.

This study intended to analyze whether the system of voucher system, which was introduced as a policy tool to expand social services, was dependent or evolving through the research methodology of historical institutionalism. The voucher system is being introduced to emphasize the user's focus in the existing supplier-centered service provision system, but problems with the existing system have been found so far. We found that despite the shift in welfare paradigm from the remaining welfare supply to universal welfare in the past, the company was partially following the existing supplier-centered social service system. However, We found that new instruments for establishing legal systems and the path evolution factors are now being developed and matured within the voucher system. In other words, it was possible to predict that the voucher system would become more positive and mature in the future through logical changes in the system. Based on the results of the analysis of the voucher system, policy suggestions for policy values and objectives that were initially oriented toward the system were presented.

본 연구는 클러스터의 역동성과 발전과정을 다규모적 접근법으로 분석하였다. 지역발전에서 지역 내부의 네트워크와 내생적 발전을 강조한 논의나 글로벌 네트워크와 조직의 역할을 강조한 논의는 모두 한계를 가지며, 외부적이고 직접적인 국가 정책이 클러스터의 역동성과 발전 과정에 미치는 역할은 과소평가되었다. 특히 강력한 정부 정책이 급속한 산업화를 이끌어온 한국의 경우 클러스터의 발전 과정에서도 국가 정책이 중요한 역할을 했다. 울산 자동차 클러스터, 대덕 연구 클러스터, 동대문 패션 클러스터의 사례에서 그 생성과 발전과정에 영향을 미친 지역 차원, 글로벌 차원의 다양한 요인들과 함께 국가 정책의 영향이 분석되었다.

Purpose: This paper reports the results of a hospital centered follow-up program on parenting stress, parenting efficacy and coping for mothers with very low birth weight (VLBW) infants. Methods: The follow-up program consisted of home visiting by an expert group and self-help program for 1 year. A non-equivalent control group pre-post quasi-experimental design was used. Participants were 70 mothers with low birth weight infants and were assigned to one of two groups, an experimental groups (n=28), which received the family support program; and a control group (n=27), which received the usual discharge education. Data were analyzed using ${\chi}^2$-test, t-test, and ANCOVA with IBM SPSS statistics 20.0. Results: Mothers' parenting stress (F=5.66, p=.004) was significantly decreased in the experimental group. There were also significant increases in parenting efficacy (F=13.05, p<.001) and coping (F=8.91, p=.002) in the experimental group. Conclusion: The study findings suggest that a follow-up program for mothers with VLBW infants is an effective intervention to decrease mothers' parenting stress and to enhance parenting efficacy and coping.

Purpose: The purpose of this study was to test a model of nursing competencies of nursing simulation learners. The conceptual model was based on the theory of Jeffries's simulaton theory. Methods: Data collection was conducted in October 2017 for 310 students from two nursing universities in Kyungbuk area for 20 days. Data analysis methods were covariance structure analysis using SPSS 21.0 and AMOS 22.0 statistical programs. Results: The hypothetical model was a good fit for the data. The model fit indices were comparative fit index=.97, normed fit index=.94, Tucker-Lewis Index=.97, root mean square error of approximation=.44, and standardized root mean square residual=.04. Teacher factors were directly related to simulation design characteristics, and it was confirmed that the curriculum, classroom operation and teaching method of the instructors were important factors. Learner factors were found to have a direct effect on nursing competence, self-confidence, and clinical performance that belong to nursing capacity. In particular, the results of this study indicate that the simulation design characteristics have a partial mediating effect on learner factors and clinical performance, and a complete mediating effect on learner factors and clinical judgment ability. Conclusion: In order to improve the learner's clinical performance and clinical judgment ability, it is necessary to conduct practical training through nursing simulation besides preparing the learner and the educator.

Purpose: This study investigated the influence of nurses' organizational communication and self-leadership on patient safety competence in comprehensive nursing care units of small and medium-sized hospitals. Methods: A descriptive design was used and self-reported questionnaires were used to collect data from 165 nurses in Seoul from February to March, 2020. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and multiple linear regression with SPSS/WIN 22.0 program. Results: A mean score of organizational communication was 3.20±0.49, self-leadership 3.58±0.50, and patient safety competency 4.01±0.49 out of 5. A significant positive correlation was found between patient safety competence, organizational communication and self-leadership. Self-leadership and combined ward explained 32% of the variance of patient safety competence (Adjusted R²=.32, p<.001). Conclusion: Patient safety competence in comprehensive nursing care units are associated with self-leadership and organizational communication. Systemic education to improve patient safety competence in small and medium sized hospitals should be implemented to promote organizational communication as well as self-leadership.
