박효정,김현진,한미영 한국교육학회 2016 敎育學硏究 Vol.54 No.4

본 연구는 초등학생의 학교폭력 경험유형에 대한 어울림 학교폭력예방 프로그램의 적용효과를 분석하여 어울림 프로그램 확산 지원에 대한 필요성을 제시하기 위해 수행되었다. 본 연구는 2015년 어울림 프로그램에 참여한 162개 초등학교에서 학생 29,404명을 대상으로 하여 학교폭력 경험유형별로 어울림 프로그램 전·후 심리사회적 역량 변화 및 학교폭력 경험유형별 어울림 프로그램 효과의 차이를 살펴보았다. 또한 이러한 심리사회적 변화가 학교적응에 어떻게 영향을 미치는가를 탐색하였다. 연구결과, 피해학생은 자기존중감, 의사소통이 긍정적으로 성장하였으며, 가해학생은 공감 및 갈등해결 역량이 성장하였고, 가피해학생과 무경험 학생은 감정조절을 제외하고 모든 심리사회적 역량이 긍정적으로 변화하였으며, 특히 무경험 학생의 심리사회적 발달 및 학교적응에도 더욱 효과적인 것으로 확인되었다. 이러한 연구결과는 어울림 프로그램이 모든 학생들의 심리사회적 발달에 긍정적 영향이 있을 뿐 아니라 긍정적인 학교문화 형성에도 기여할 것이라는 점을 시사하였다. 본 연구에서는 어울림 프로그램이 초등학교의 단위학교로 확산되는 데에 필요한 실증적 자료를 제시하였다는 점에서 연구의 의의가 있다. To suggest the importance of expending support on Aulim school violence prevention programs, this study investigated the effects of the Aulim school violence prevention programs according to elementary school students’ school bullying experience types. Participants were 29,404 students in 162 elementary schools participating 2015 Aulim programs. This study inquired the Aulim programs’ effects on changes of psychosocial competence according to school bullying experience types. Also, we investigated how the changes of pschosocial competence influenced students’ school adjustment. The results show that positive improvement were revealed in self-esteem, communication skills among victims, in empathy and conflict resolution among bullies, and all psychosocial competence except emotional regulation among bully-victims and non-school bullies. Especially, the programs were the most influential on non-school bullies’ psychosocial development and school adjustment. These results imply the Aulim programs will enhance all students’ positive development and school environment. This study suggested that the results supplies the practical evidences to expend the Aulim programs in elementary schools.

This study investigated the quality characteristics and antioxidant activity of muffins prepared with different amounts (0%, 5%, 10%, and 15%) of aronia powder. The moisture content was higher in the groups that contained aronia powder than in the control muffin. The specific volume of the muffins was lowest in the group with 15% aronia powder added. The lightness and yellowness values decreased, while the redness values increased with increasing amounts of the aronia powder. The hardness of the control group was lower than that of the 10% and 15% treatment groups. The consumer acceptance test revealed no significant differences in the taste and texture of the muffin samples, but the overall acceptability scores were lowest for the muffins with 15% aronia powder added. The substitution of wheat flour for the aronia powder yielded muffins with a higher polyphenol content and total flavonoid content. The antioxidant activity measured via the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity, metal chelating effect, and reducing power increased as the concentration of the aronia powder increased. The results showed that up to 10% aronia powder can be incorporated into muffins to meet the sensory quality and functional needs of consumers.

리더의 감사표현이 조직구성원의 업무성과에 미치는 영향: 조직몰입과 심리적 안전감의 매개효과를 중심으로

박효정,박정민 연세대학교 사회과학연구소 2023 社會科學論集 Vol.54 No.2

이 연구는 조직 맥락에서 감사표현의 영향을 확인하고자 하였다. 특히 구성원의 업무성과를 향상시키기 위한 선행요인으로 리더의 감사표현(gratitude expression)에 초점을 맞춰 리더의 감사표현이 조직구성원의 업무성과에 미치는 영향과 조직몰입 및 심리적 안전감을 통한 간접 메커니즘을 규명하고자 하였다. 국내 다 국적 기업에 근무하는 판매직 직원 147명을 대상으로 구조방정식 모형을 활용하여 분석한 결과, 리더의 감사 표현은 구성원의 업무성과에 대한 직접적 영향은 없었으나, 조직몰입과 심리적 안전감에는 정(+)의 영향을 나타냈다. 또한 리더의 감사표현은 구성원의 조직몰입을 매개로 업무성과에 정(+)의 영향을 미쳤다. 이 연구 는 조직 맥락에서 수행된 감사표현 관련 연구가 부족한 가운데 리더의 감사표현과 업무성과의 관계에 대한 이해를 확장했다는데 그 의의가 있다. This study aimed to investigate the impact of gratitude expression within the organizational context. Specifically, our focus was on the leader gratitude expression as a antecedent to enhancing employees' work performance. We aimed to determine how leader gratitude expression affects work performance and the indirect mechanisms involving organizational commitment and psychological safety. Using a structural equation model with 147 Korean sales employees employed at a multinational company, our findings indicated that leader gratitude expression did not directly impact employees' work performance. However, it did have a positive influence on both organizational commitment and psychological safety among employees. Furthermore, leader gratitude expression positively affected work performance through employees' organizational commitment. This study extends our understanding of the relationship between leader gratitude expression and work performance, given the lack of research on gratitude in the organizational context.

주름 기법을 이용한 섬유제품 개발 - 누노펠트 기법 중심으로 -

박효정,김성연 한국기초조형학회 2019 기초조형학연구 Vol.20 No.2

The purpose of this study was to explore the possibilities of new formability fibers by using wrinkle shape in wool felt technique and to suggest the development possibility of nuno felt fabric by developing products using it. Wrinkles are a formative element that can be seen in various forms in various fields of visual arts. In this research, however, wrinkles appearing in textile fashion field, which is commonly called pleats, were researched. In addition, research on wrinkles in textiles has shown that the three-dimensional form, which is a characteristic of wrinkles, gives rise to diversity in the texture of the material surface, which is likely to develop into a high-value-added industry with rich and original formative expression and artistry . The characteristic of Nuno felt wrinkle is that it is easy to combine with various other fibers compared to existing wrinkle processing, and it is possible to express a unique three- dimensional texture that is generated thereby. In order to present the possibility of wrinkle of Nuno felt as a textile material that can highlight the artistry in the textile industry, I have developed products focusing on fashion and household goods. As a result of research, it was found out that wrinkle processing in fashion and various fields is being used as a design for enhancing artistic expression and pursuing expression with the help of designers' products using wrinkles. Among the handicraft techniques that are difficult to mass-produce, the products with unique three-dimensional wrinkles expressed by the Nuno Felt technique are considered to be easy to satisfy consumers' desire to find differentiated products with various characteristics, and the development potential is also high. 본 연구의 목적은 양모펠트 기법 중 누노펠트 작업에서 나타나는 주름의 형태를 이용하여 새로운 조형성을 가지는 섬유의 가능성을 모색하고, 그것을 이용한 제품을 개발하여 누노펠트 직물의 발전 가능성을 제시 하고자하였다. 주름은 시각예술의 여러 분야에서 다양한 형태로 볼 수 있는 조형의 한 요소이지만, 본 연구에서는 통상적으로 플리츠라 불리는 것으로서 주로 섬유패션 분야에 나타난 주름을 조사 연구 하였다. 또한, 섬유 분야에서의 주름에 관한 연구를 통해 주름의 특성인 입체적 형태가 소재 표면의 질감에 다양성을 주어 풍부하고 독창적인 조형 표현과 예술성을 가진 고부가 가치 산업으로 발전할 가능성이 많음을 밝히고자 하였다. 누노펠트 주름의 특징은 기존 주름 가공에 비하여 다른 여러 가지 섬유와의 결합이 용이하고 그로인해 발생되는 독특한 입체적 질감 표현이 가능 하다는 것이다. 그리하여 섬유 산업에서 예술성을 부각시킬 수 있는 섬유 소재로서의 누노펠트 주름의 가능성을 제시해 보고자 패션과 생활용품 중심으로 제품 개발을 해 보았다. 연구결과 주름을 활용한 디자이너들의 상품 연구를 통해 현대에는 패션 및 다양한 분야에서 주름 가공이 개성 있는 표현 추구와예술성을 높이는 디자인으로 활용되고 있다는 것을 알 수 있었다. 대량 생산이 어려운 수공예 기법 중 누노펠트기법으로 독특한 입체 주름이 표현된 제품들은 다양한 개성으로 차별화된 제품들을 찾는 소비자의 욕구를 충족하기에 용이하다고 여겨지며, 발전 가능성 또한 높을 것으로 생각된다.

To investigate the frequency and clinical significance of detected incidental lung nodules found on computed tomography (CT) simulation images for hepatocellular carcinoma (HCC) using computer-aided diagnosis (CAD) and a physician review. Materials and Methods: Sixty-seven treatment-naïve HCC patients treated with transcatheter arterial chemoembolization and radiotherapy (RT) were included for the study. Portal phase of simulation CT images was used for CAD analysis and a physician review for lung nodule detection. For automated nodule detection, a commercially available CAD system was used. To assess the performance of lung nodule detection for lung metastasis, the sensitivity, negative predictive value (NPV), and positive predictive value (PPV) were calculated. Results: Forty-six patients had incidental nodules detected by CAD with a total of 109 nodules. Only 20 (18.3%) nodules were considered to be significant nodules by a physician review. The number of significant nodules detected by both of CAD or a physician review was 24 in 9 patients. Lung metastases developed in 11 of 46 patients who had any type of nodule. The sensitivities were 58.3% and 100% based on patient number and on the number of nodules, respectively. The NPVs were 91.4% and 100%, respectively. And the PPVs were 77.8% and 91.7%, respectively. Conclusion: Incidental detection of metastatic nodules was not an uncommon event. From our study, CAD could be applied to CT simulation images allowing for an increase in detection of metastatic nodules.

Heart Rate Variability as a Measure of Disease State in Irritable Bowel Syndrome

박효정 한국간호과학회 2008 Asian Nursing Research Vol.2 No.1

Heart rate variability (HRV) is a noninvasive measure of sympathovagal balance in the autonomic nervous system (ANS). This review will: (a) consider HRV measurement in irritable bowel syndrome (IBS); (b) discuss the applicability of HRV measurement in IBS by addressing strengths and limitations; and (c) propose future directions in this field of gastrointestinal research and clinical practice. As a strength, analyzing HRV components is a useful method and appears most suitable for detection of changes in ANS sympathovagal balance in both stress and non-stress conditions with good validity and reliability. Also, it is an appropriate measure for ANS in studies with large populations, in both laboratory and clinical settings, and for longitudinal studies because of its noninvasive assets. With regard to limitations of measuring HRV, these are poor standardization, additional human editing, not considering medication or other confounding factors, inconsistent results in gastrointestinal vagal tone study, and different time periods.

「언문철자법」(1930)에 대한 재고찰

박효정,김수안,김주성 한국문학언어학회 2024 어문론총 Vol.98 No.-

이 연구는 「언문철자법」(1930)의 전체적인 구성과 각 조항을 역사적 맥락을 바탕으로 다시 해석하여 그것의 가치를 재평가하는 것을 목적으로 한다. 「보통학교용 언문철자법」(1912)와 「보통학교용 언문철자법 대요」(1921)에서는 고유어와 한자음을 구분하여 표음적 표기와 역사적 표기를 하였는데 「언문철자법」(1930)에서는 확고한 표음적 표기를 마련하여 고유어와 한자음을 모두 표음적으로 표기하고 표음주의의 표의화를 시도함으로써 근대 우리말 표기법의 기준을 마련하였다는 데에 의의가 있다. 「언문철자법」(1930)에서 발음대로 표기한다는 원칙은 언문일치를 바탕으로 하는데 그것은 형태 표기와 배치되는 것이 아니기 때문에 각론에서 ‘표음문자의 시각화’를 위한 조항이 명시될 수 있었다. 또한 「언문철자법」(1930)에서는 조선어와 일본어의 대응 관계를 가정하여 재현하려는 시도가 더욱 정교하게 이루어졌다. 총독부는 「언문철자법」(1930)을 통해 조선어와 일본어의 대응 관계를 재현하고 조선어와 일본어의 교환 가능성을 기사화하려는 시도를 보였다. 그러나 이러한 대응 관계에 균열을 일으키는 지점을 확인할 수 있었는데 이것은 식민지 조선에서 도모된 언어 규율의 특수성을 시사한다. This study seeks to reevaluate the overall organization and value of eonmuncheoljabeob (the Korean Spelling System) by reinterpreting each article in its historical context. In botonghaggyoyong eonmuncheoljabeob (The Orthography for Ordinary Schools) and botonghaggyoyong eonmuncheoljabeob daeyo (Outline of the Orthography for Ordinary Schools), phonetic and historical markings were used to distinguish between native words and Chinese character sounds, but in eonmuncheoljabeob, a firm phonetic marking system was established, representing the standard for modern Korean notation. While the principle of transliteration in eonmuncheoljabeob is based on phonetic congruence, it is not incompatible with a morphologically-based notation, so provisions could be made in the footnotes for the “visualization of ideographs.” Furthermore, in eonmuncheoljabeob, a more elaborate attempt was made to reproduce the assumed correspondence between Korean and Japanese, representing the attempt of the Japanese government-general of Korea to articulate the interchangeability of Korean and Japanese. However, it was possible to identify points where this correspondence broke down, suggesting the specificity of the language discipline promoted in colonial Korea.
