This paper aims to compare and verify the antibacterial effects of cotton fabrics naturally dyed with extracts of Ulmus davidiana var. japonica Nakai, Caesalpinia sappan, Saururus chinensis, and Artemisia princeps against antibiotic-resistant strains of bacteria. After natural dyeing of the test fabric, Al, Cu, Fe mordants were used. The color fastness against washing, rubbing, and perspiration of the cotton fabrics dyed with the 4 types of extracts were mostly excellent. However, the color fastness against light showed poor results for all four types. As for the antibacterial test method, MRSA (ATCC 33591) was applied to the cotton fabrics dyed with the four kinds of extracts and cultured for 24 hours. After that, the bacteria that proliferated on the fabrics were collected and spread on a solid medium. The bacteria were measured to find out the bacteriostatic reduction rate for the antibiotic-resistant strains. As a result of the analysis, all four extracts showed a high bacteriostatic reduction rate of more than 99% when the copper mordant was used. Even with the lack of a mordant, the bacteriostatic reduction rate was high, at 99.9% for Caesalpinia sappan and 94.6% for Saururus chinensis.

The purpose of this study was to examine Koryo women’s hairstyle reproduced in visual media and to explain the importance of historical investigation and the reproduction of hairstyle, which should be changed according to age. For this study, we analyzed three historical dramas with the early, mid and late periods of the Koryo Dynasty as their background, investigated hairstyle in the Koryo Dynasty using old literature, Buddhist paintings from the Koryo Dynasty, figure paintings on walls, and relics, and collected data related to visual media using photographs on the Internet. According to the results of this study, the hairstyle in drama ‘Queen Cheonchu’ with the early Koryo Dynasty as its background should have reproduced Gogye, the hairstyle in the Shilla Dynasty because, during its early period, Koryo established all its systems based on those from Shilla. However, the hairstyle in Queen Cheonchu seems to have reproduced the hairstyle in the late Koryo Dynasty rather than that in its early period. Court ladies in drama ‘The Age of Warriors’ with the mid Koryo Dynasty as its background show hairstyle quite similar to the style of the women in Munhigwihwando. According to Koryodogyeong (1123) written during the reign of the 17th King Injong, which is the same period as the Age of Warriors, gisaengs’ hairstyle was called Chumagye. The hairstyle of gisaengs appearing in The Age of Warriors also reproduced Chumagye well. In movie ‘Ssanghwajeom’ with the late Koryo Dynasty as its background reproduced Princess Noguk, who was King Gongmin’s wife, and her hairstyle was similar to that of Princess Noguk in her portrait. However, while the hairstyle in the queen’s lady attendants in Gwangyeongseobunbyeonsangdo painted in the late Koryo Dynasty was tied up, the hairstyle of court ladies in the movie is similar to that of the noble woman in Gwangyeongbonbunbyeonsangdo. According to relics from the late Koryo Dynasty, court ladies’ hairstyle is believed to be closer to Gogye. 이 연구는 영상매체에 재현되어진 고려여인의 수발양식을 살펴보기 위해 고려시대의 전기, 중기 그리고 후기를 배경으로 한 세편의 사극을 선정하여 분석하였다. 고려시대의 수발양식은 고문헌, 고려불화, 벽화인물도 그리고 유물 등을 중심으로 살펴보았고 영상매체에 관련된 자료는 인터넷 검색을 통해 사진 자료를 수집하여 비교하였다. 연구결과 고려 초를 배경으로 한 천추태후의 수발양식은 오히려 고려 초의 고계보다는 고려말의 수발양식을 재현한듯하다. 고려 중기를 배경으로 한 무인시대의 상궁의 수발양식은 문희귀환도의 여인의 머리장식과 매우 흡사하며 기녀의 수발양식도 고려도경(1123)에 묘사되어진 기녀의 머리형태인 추마계로 잘 재현해 놓았다. 고려 말을 배경으로 한 쌍화점은 노국공주의 모습을 유사하게 재현하였다. 그러나 왕실시녀의 수발양식은 고려 말에 그려진 관경서분변상도에 의하면 고계형태에 더 가까울 것으로 생각되어진다.

최나영 사단법인 한국융합기술연구학회 2024 아시아태평양융합연구교류논문지 Vol.10 No.3

본 연구는 간호대학생의 영아 응급간호 시뮬레이션 프로그램을 개발하고 응급간호 지식, 임상 판단 및 임상 수행능력의 효과를 확인하고자 시행되었다. 대상자는 실험군과 대조군으로 나뉘었으며 대조군은 강의식 수업만을 받고 실험군은 강의식 수업과 시뮬레이션 수업을 받아 응급간호 지식, 임상 판단과 임상 수행능력의 차이를 분석하였다. 본 연구는 비 동등성 대조군 사전-사후 설계이며 자료는 SPSS WIN 26.0을 사용하여 분석하였다. 일반적 특성과 변수들은 퍼센트와 표준편차로, 대상자의 동질성과 가설은 χ²과 paired t-test로 분석하였다. 본 연구는 학생 당 10시간(강의 2시간, 시뮬레이션 8시간) 시행되었다. 영아 응급간호 시뮬레이션은 3개의 수업(프리브리핑, 러닝, 디브리핑)으로 구성되었다. 연구결과는 임상 판단과 임상 수행능력이 유의미하게 개선되었다. 그러므로, 타당성이 검증되고 표준화된 영아 응급간호 시뮬레이션 프로그램은 대학생의 시뮬레이션 훈련을 위해 사용될 수 있다. This study aimed to develop an emergency care simulation program for nursing college students based on their knowledge of emergency care, clinical judgment, and clinical practice ability. Nursing students who participated in this study were divided into experimental and control groups. The subjects in the control group received only lecture education, and the experimental group received lecture and simulation education to observe the differences in their knowledge of emergency care, clinical judgment, and clinical practice ability. This study used a non-equivalent control pre-post design, and the data were analyzed using SPSS WIN 26.0. The general characteristics, values, percentages, and standard deviations were analyzed. In addition, the subject’s homogeneity and hypotheses were analyzed with χ² and paired t-tests. This research program was applied for 10 hours (lecture education: 2 hours and simulation program: 8 hours) per person. The emergency care simulation program for infants was provided in three classes (pre-briefing, running, and debriefing). The results indicated that clinical judgment and clinical practice ability for nursing simulation significantly improved. The emergency care simulation program for infants for nursing college students positively affected student’s clinical judgment and clinical practice ability. Therefore, this validated and standardized emergency care simulation program for infants can be used to train simulations of college students.

Cell Surface Properties and Biofilm Formation of Pathogenic Bacteria

최나영,배영민,이선영 한국식품과학회 2015 Food Science and Biotechnology Vol.24 No.6

Cell surface properties of slime production, cell hydrophobicity (CH), colony spreading, auto-aggregation, and biofilm formation (BF) of pathogens were investigated. Staphylococcus aureus, Pseudomonas aeruginosa, and Listeria monocytogenes generally formed strong biofilms and were positive slime producers. The extracellular polymeric substances isolated from agar-grown biofilms of Bacillus cereus and P. aeruginosa contained a high proportion of carbohydrates, proteins, and extracellular DNA. High levels of CH were observed for all pathogens when hydrocarbons were combined with ammonium sulfate (AS). Levels of hydrophobicity based on bacterial adhesion to hydrocarbons using nonane with AS were positively correlated with hydrophobic interaction chromatography assay and contact-angle measurement results. BF and CH values of all pathogens, except E. coli O157:H7 and B. cereus, were highly correlated. Levels of pathogen hydrophobicity differed depending on the measurement method. Factors affecting BF were different depending upon the pathogen.

최나영,박순찬,이정민,류창우,장건호 대한자기공명의과학회 2019 Investigative Magnetic Resonance Imaging Vol.23 No.3

Purpose: The purpose of this study was to investigate if double inversion recovery (DIR) imaging can have a role in the evaluation of brain ischemia, compared with diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR) imaging. Materials and Methods: Sixty-seven patients within 48 hours of onset, underwent MRI scans with FLAIR, DWI with b-value of 0 (B0) and 1000 s/mm2, and DIR sequences. Patients were categorized into four groups: within three hours, three to six hours, six to 24 hours, and 24 to 48 hours after onset. Lesion-to-normal ratio (LNR) value was calculated and compared among all sequences within each group, by the Friedman test and conducted among all groups, for each sequence by the Kruskal- Wallis test. In qualitative assessment, signal intensity changes of DIR, B0, and FLAIR based on similarity with DWI and image quality of each sequence, were graded on a 3-point scale, respectively. Scores for detectability of lesions were compared by the McNemar’s test. Results: LNR values from DWI were higher than DIR, but not statistically significant in all groups (P > 0.05). LNR values of DIR were significantly higher than FLAIR within 24 hours of onset (P < 0.05). LNR values were significantly different between, before, and after six hours onset time for DIR (P = 0.016), B0 (P = 0.008), and FLAIR (P = 0.018) but not for DWI (P = 0.051). Qualitative analysis demonstrated that detectability of DIR was higher, compared to that of FLAIR within 4.5 hours and six hours of onset (P < 0.05). Also, the DWI quality score was lower than that of DIR, particularly relative to infratentorial lesions. Conclusion: DIR provides higher detectability of hyperacute brain ischemia than B0 and FLAIR, and does not suffer from susceptibility artifact, unlike DWI. So, DIR can be used to replace evaluation of the FLAIR-DWI mismatch.

최나영,한상준,장광진,Choi, N.Y.,Han, S.J.,Chang, K.J. 국립한국농수산대학교 교육개발센터 2018 현장농업연구지 = Journal of practical agricultural resear Vol.20 No.1

This study was initiated because many studies would be necessary to promote Korean ginseng products when the sales of Korean ginseng are declining and many Korean ginseng farmers are facing economic difficulties. The increase in domestic sales is important, but this study is targeting for foreigner's perceptions of Korean ginseng and how to improve the products. The goal of this study is to analyze how to increase their purchase intentions of Korean ginseng products. Questionnaire survey research methods were used to learn more about making certain improvements to ginseng products, consumers are hoping, how affect their perceptions and purchase intentions of Korean ginseng, as well as how foreigners' perceptions of Korean ginseng products affects purchase intentions. Because it's difficult to find any studies about foreigner's Korean ginseng purchase intentions, the survey was expanded to include how people take care of their health, the accessibility of purchasing ginseng products, psychological factors as well as consumer characteristics, satisfaction with Korean ginseng, and intentions of buying Korean ginseng products. The result of the analysis on how making certain desired improvements to and perceptions of Korean ginseng products affect purchase intentions indicated that Korean ginseng perceptions highly affected the purchase intentions; however making certain improvements to ginseng products showed a low impact on the purchase intentions. In other words, making certain improvements, such as convenience of the ginseng products, doesn't affected Korean ginseng purchase intentions directly. On the other hand, it showed that the usefulness, its high quality, and safety trust of Korean ginseng have a big impact on purchasing intentions. If the ginseng that is grown and processed in Korea is better promoted for its high value, the Korean ginseng farmers who are facing many economic difficulties will be able to raise their income.

최나영,조남기 한국여성체육학회 2019 한국여성체육학회지 Vol.33 No.4

The purpose of this study was to develop a tangible scale based on student's behavior to evaluate student's character development in the sport club activity. The results of this study are as follows. Three characters of democratic citizenship, respect for others and self-esteem were included from general characters, and eight sub-factors for those three general characters such as rule observance-ethics, fairness, responsibility, empathy, consideration, cooperation, fairness and sensitivity were screened out. With regards to sports-specific sub-factors, twelve were filtered out of literature review, FGI and delphi. Therefore, eight of sub-factors from general characters and twelve sub-factors from sport circumstances are included in the final rubric except the one redundant both in the general and the sport-specific sub-factors. The purpose of this study was to develop a rubric to evaluate student's character development in the school sport club activity and provide a hands-on scale that relies on student's behavior that is observable. It is hopefully expected that the characters and the sub-factors developed in this study provide sport club instructors with what characters to aim to teach and how to help student learn them as well as what and how to evaluate student's affective development. In addition, it is also expected that the results of this study contributes to refresh societal interest and disseminate the needs for character education in sport education. 본 연구는 스포츠 상황에서 교사가 관찰 가능한 학생의 행동 특성이 무엇인지 알아보고, 이를 토대로 스포츠 인성 평가 루브릭을 개발하는 것에 그 목적이 있다. 본 연구의 결과는 다음과 같이 나타났다. 첫째, 문헌 연구와 FGI를 통해 인성의 범주는 민주시민의식, 타인존중의식, 자기존중의식으로 구분되었고, 8개의인성(준법, 정직, 성실, 공감, 배려, 협동, 공정, 감성) 구인으로 나누었으며, 스포츠 인성의 요소는 12가지(규칙준수, 태도, 정직, 성실, 소통, 이타심, 봉사, 리더십, 팔로우십, 존중, 자기조절, 도전정신)로 구분되었다. 둘째, 문헌 연구와 FGI를 통해 작성된 루브릭 초안은 과제 일반적 루브릭, 분석적 루브릭 형태로 작성되었으며, 평가의 척도는 우수, 보통, 미흡, 3가지의 척도로 설정하였다. 셋째, 개발된 인성 평가 루브릭의 타당도를 알아보기 위해 델파이 기법을 활용하였으며, 최종적으로 도출된 루브릭은 민주시민의식, 타인존중의식, 자기존중의식, 3가지의 인성 범주로 구분되며, 8가지의 인성 구인과(준법-윤리, 공정, 책임감, 공감, 배려, 협동, 공정, 감성), 12가지의 스포츠 인성 요소로 구분되었으며, 19개의 평가 항목으로 도출되었다. 본 연구는 학교스포츠클럽 활동에서의 인성 평가 루브릭을 개발함으로써, 현장에서 평가하는 지도자들에게 평가의 지표를 제공하고자 하였다. 또한 지도자와 학생 모두에게 올바른 인성 행동 특성을 제시함으로써, 학생의 행동 교정을 위한 교사의 즉각적인 피드백이 가능할 것이라고 기대해본다. 더불어 본 연구의결과가 실제로 활용될 수 있는 인성 평가에 대한 논의의 장을 시작하고 확대하는 것에 의미가 있다고 볼 수있다.

This study aimed to investigate the effects of nursing simulation education about child care with acute asthma attacks for nursing students. Nursing students that participated in this study were divided into experimental and control groups. The subjects in the control group received the video education and the subjects in the experimental group received the simulation education to observe the differences in the problem solving processes, self-efficacy and learning satisfaction. This study used a non-equivalent control pre-post design and data were analyzed using SPSS WIN 22.0. The general characteristics and the values of the variables along with percentages and standard deviation were analyzed. In addition, the subjects homogeneity and t-test hypotheses were analyzed. The difference in the subjects’ scores before and after the video education program were statistically significant in the self-efficacy(t = 3.08, p < .004) and learning satisfaction(t = 3.46, p <.003). The findings indicate that this simulation would be useful in improving self-efficacy and learning satisfaction for child care with asthma attack in nursing students.
