Park, Jaeyeon,Kang, Bong Joo,Kim, Sung Hun,Lee, Jeongmin,Lee, Ahwon Korean Society of Magnetic Resonance in Medicine 2021 Investigative Magnetic Resonance Imaging Vol.25 No.2

Breast angiosarcoma is a very rare manifestation. Herein, we report a case of breast angiosarcoma in a 21-year-old woman admitted to our hospital with a one-year history of a palpable mass with fullness and swelling of the right breast. The various imaging findings, including mammography, ultrasound (US), and magnetic resonance imaging (MRI), of this rare disease are described. The imaging findings of US and combined MRI of breast angiosarcoma were specific in this case. The imaging characteristics could be helpful in detecting and diagnosing breast angiosarcoma in young women with a palpable mass with fullness and swelling of the breast.

In every summer, cicadas emerge and become numerically and ecologically dominant in Korean penninsula. Especially, cicada emergence is affected by the environmental factors. In order to evaluate the effect of environmental factors in cicada species, we analyzed the temporal changes in cicada exuviae based on meteorological and non-meteorological factors such as artificial light intensity and habitat characters on urban park area surrounded by residential houses. Combined multivariate analyses with a cluster analysis and a principal component analysis (PCA) were conducted. Samples were classified into 3 different cluster based on differences of meteorological factors such as temperature and humidity. Moreover, Random Forest model (RF) showed a high predictability of daily mean temperature on species peak abundance. These results provide a strong evidence that meteorological factors have significant effects on cicada emergences. Regarding the non-meteorological factors, we found no relationship in cicada emergence.

Easy and rapid quantification of lipid contents of marine dinoflagellates using the sulpho-phospho-vanillin method

Park, Jaeyeon,Jeong, Hae Jin,Yoon, Eun Young,Moon, Seung Joo The Korean Society of Phycology 2016 ALGAE Vol.31 No.4

To develop an easy and rapid method of quantifying lipid contents of marine dinoflagellates, we quantified lipid contents of common dinoflagellate species using a colorimetric method based on the sulpho-phospho-vanillin reaction. In this method, the optical density measured using a spectrophotometer was significantly positively correlated with the known lipid content of a standard oil (Canola oil). When using this method, the lipid content of each of the dinoflagellates Alexandrium minutum, Prorocentrum micans, P. minimum, and Lingulodinium polyedrum was also significantly positively correlated with the optical density and equivalent intensity of color. Thus, when comparing the color intensity or the optical density of a sample of a microalgal species with known color intensities or optical density, the lipid content of the target species could be rapidly quantified. Furthermore, the results of the sensitivity tests showed that only $1-3{\times}10^5cells$ of P. minimum and A. minutum, $10^4cells$ of P. micans, and $10^3cells$ of L. polyedrum (approximately 1-5 mL of dense cultures) were needed to determine the lipid content per cell. When the lipid content per cell of 9 dinoflagellates, a diatom, and a chlorophyte was analyzed using this method, the lipid content per cell of these microalgae, with the exception of the diatom, were significantly positively correlated with cell size, however, volume specific lipid content per cell was negatively correlated with cell size. Thus, this sulpho-phospho-vanillin method is an easy and rapid method of quantifying the lipid content of autotrophic, mixotrophic, and heterotrophic dinoflagellate species.

『필사본 고어대사전』 편찬에 대하여 : 번역고소설 활용을 중심으로

박재연(Park Jaeyeon) 한국사전학회 2010 한국사전학 Vol.- No.16

This thesis reviews the characteristics, structure and the resources used for the Dictionary of Archaic Words of Korean Manuscripts and focuses on its use with regard to reading translated ancient Korean Novels. The dictionary is distinct in the way it has been compiled : It contains a wealth of material uncollected in the previous dictionaries, including proper nouns, extant words and Chinese words. It also lays out original Chinese texts in parallel with the translated passages. With the entries of 70,000, more than 180,000 examples and over 6,000 pages, the Dictionary of Archaic Words of Korean Manuscripts will serves as a guide for basic research on numerous areas of studyt as well as students of Korean studies. It will also help one to more easily read ancient Korean novels written in Chosun dynasty. This dictionary has not complied with the current dictionary publication method of resorting to a corpus but opted for the traditional manual work. Which accounts for fewer examples of more frequently used words and more examples of less frequently used words. Its head words are mostly composed of nouns, verbs and adjectives. Suffixes and conjugated endings have been given a short shrift. Solace may be found in the knowledge that this is a interim byproduct in the course of compiling the Ancient Korean Dictionary.

박정숙 ( Park Jeongsook ),박재연 ( Park Jaeyeon ),박주혜 ( Park Juhye ) 열린부모교육학회 2017 열린부모교육연구 Vol.9 No.3

본 연구의 목적은 장애자녀를 둔 양육자의 학부모로서의 경험과 생각을 듣고, 현실적인 어려움을 분석하고, 개선점을 모색하고자 하는 것이다. 이를 위해 현재 장애자녀의 취학을 경험하고 있는 주 양육자 10명을 선정하여 인터뷰 하였다. 반구조화된 질문들을 활용하여 1:1 면담의 방식으로 진행했으며, 추출되어진 자료는 합의적 질적 연구방법(Consensual Qualitative Research: CQR)에 의해 분석하였다. CQR 분석을 통해서 최종적으로 추출된 9개의 영역을 장애자녀의 진학에 대한 경험, 장애자녀의 학부모로서의 경험, 향후 진학과 진로에 대한 생각의 3개의 영역으로 나누어 분석하였다. 연구의 결과를 근거로 장애자녀의 초등학교 입학과 학교생활 그리고 진로에 대한 실천적, 정책적 함의를 제시하였다. The purpose of this study is to listen to parental experiences and thoughts of parents having with a disabled child, analyze realistic difficulties and find improvement points. To do this, there were interviews after choosing 10 main caregivers who are currently sending children with disabilities to school. It was implemented as one and one interview method taking advantage of the semi-structured inquiry and the extracted data were analyzed by consensual qualitative research (CQR). The nine areas finally extracted through the CQR analysis were divided into three areas: experience on admission of a disabled child, experience as a parent of a child with a disability, and thoughts about future admission into a school and career. Based on the results of this study, we suggested practical and policy implications about elementary school admission, school life and career of children with disabilities.

Du point de vue de la représentation ou de la reproduction, deuxième moitié du XIX e siècle attire nos regards. Tout au long du siècle, on voit tant de mutations sociales, économiques et culturelles. En parlant sur l’art de ce riche siècle, on a tendance à penser que l’impressionnisme et leurs héritiers offrent une sorte de motricité définitive à l’histoire de l’art et à lui laisser la place auréolée. Pourtant, les impressionnistes n’étaient pas seuls, qui démontrent une très sincère adhésion à l’époque et le désir de coïncider avec elle. On constate que le naturalisme a joué le rôle important dans ces représentations visuelles de la société. Malgré la racine idéologique du réalisme, le naturalisme fait l’éloge de l’expression des détails elles-mêmes qui nous demandent une interprétation sociale. Les peintres naturalistes se consacrent à la description exacte de la vie réelle en faisant penser les spectateurs aux autres références habituelles et en créant une sorte de narrativité. Les oeuvre d’Henri Gervex, chargées des matériaux référentiels, nous offrent un trou à travers lequel on observe la société ostentatoire. Ce qui fait le peintre naturaliste est l’œil d’introspection, pas l’habileté de la main, avec laquelle n’aboutit qu’à un art de l’illusionnisme formel. Il serait toutefois très exagéré de conclure que la peinture mondaine peut être élevée au rang du « grand art ». Pourtant, elle vaut une évaluation plus sérieuse en tant que produit de la société ayant besoin de préserver ses goûts, coutumes, et styles de vie. Cette considération pourrait contribuer à élargir nos perspectives sur l’art français du XIX e siècle, estimé pendant longtemps comme une liste des étiquettes des maîtres modernes.

청소년의 학업스트레스, 학교폭력, 주관적 행복감 의 관계: 친구, 가족, 교사의 지지의 매개효과를 중심으로

박재연 ( Jaeyeon Park ) 경희대학교 사회과학연구원 2017 社會科學硏究 Vol.43 No.2

본 연구는 사회복지실천현장에서 청소년의 주관적 행복감을 증진시킬 수 있는 전략을 마련하기 위해 주요 관련 요인인 학업스트레스, 학교폭력, 주관적 행복감의 관계를 검증한 후 친구, 가족, 교사의 지지가 매개요인으로서 어떠한 기능을 하는지 모형 내 구조적 관계를 규명하였다. 그 결과, 학업스트레스는 주관적 행복감에 부적 영향을, 매개요인인 친구의 지지, 가족의 지지, 교사의 지지에 부적 영향을 미치고 있었다. 친구의 지지, 가족의 지지, 교사의 지지는 학업스트레스와 주관적 행복감 사이를 매개하고 있었다. 학교폭력은 친구의 지지, 가족의 지지, 교사의 지지에 부적 영향을 미치고 있었으며, 친구의 지지, 가족의 지지, 교사의 지지는 학교폭력과 주관적 행복감 사이를 매개하고 있었다. 매개요인들의 효과 분해 결과, 친구의 지지, 가족의 지지, 교사의 지지의 순으로 큰 영향을 미치는 것으로 나타났다. 본 결과를 바탕으로 주관적 행복감을 증진시킬 수 있는 사회복지실천 방안을 논의하였다. This study examines the structural relationships between risk/protective factors and adolescent subjective happiness. As risk factors, we chose academic stress and school violence. As protective factor, friend, family and teacher`s support were chosen. As a result, academic stress had significant negative effects on subjective happiness, while school violence influenced via friend, family and teacher`s support. Friend, family and teacher`s support had negative effects on subjective happiness. The results of mediator factors showed that there were significant influences in the order of friend support, family support and teacher`s support. These findings can contribute to implementing the policies for the promotion of subjective happiness.
