서은영,Seo, Eunyoung 한국식생활문화학회 2018 韓國食生活文化學會誌 Vol.33 No.5

Purpose: This study examined the effects of ${\alpha}$-lipoic acid in diluted solvents on cell growth in 3T3-L1 cells according to the treated concentration and times. Methods: Adipocyte 3T3-L1 cell were cultured. Confluent cells underwent starvation with SFM for 1 day and then were cultured in a medium containing various concentrations 0, 100, 200, and $400{\mu}mol/L$ of ${\alpha}$-lipoic acid. The cell viability was measured using the EZ Cytox assay kit. In addition, the effect of ${\alpha}$-lipoic acid of diluted solvents on the cell growth in 3T3-L1cells was examined according to the treated concentration and times. Results: The ${\alpha}$-lipoic acid diluted ethanol inhibited cell proliferation in a dose and time dependent manner. The ${\alpha}$-lipoic acid diluted ethanol induced adipocyte 3T3-L1 cells proliferation with an adipocyte inducer. In addition, ${\alpha}$-lipoic acid inhibited adipocyte 3T3-L1 growth in a dose and time dependent manner (p<0.05). Conclusion: This study showed that a treatment with ${\alpha}$-lipoic acid diluted ethanol inhibits cell growth of, adipocyte 3T3-L1 cells induced with an adipocyte inducer, ($200{\mu}mol/L$ of ${\alpha}$-lipoic acid) treated for 48 hr.

유방암 환자들의 심리적 대처 과정

서은영(Eunyoung E. Suh) 대한스트레스학회 2008 스트레스硏究 Vol.16 No.4

본 연구는 국내 여성 암 발생률 1위인 유방암을 진단 받은 암환자들이 유방암이라는 스트레스에 심리적으로 대처해가는 과정을 탐구하기 위해 수행되었다. 질적 연구방법론의 하나인 근거이론 방법론을 사용하여 지방의 한 암 진료기관에 내원한 열일곱 명의 유방암 환자들을 대상으로 개인별 심층면담을 수행하였다. 녹음한 면담 내용은 녹취록으로 변환하여 순환적 분석기법을 이용하여 분석하였다. 도출된 중심 주제는 “지나가는 고통을 마음을 낮추어 받아들이고 견뎌냄”이라는 상황 특이적 이론으로 “마음을 비우고 물 흐르는 데로 살아감”과 “마음을 단단히 먹고 버텨냄” 등의 두 하부 주제를 포함하고 있다. 마음을 낮추고 유방암을 인생의 수많은 고통 중 하나로 받아들이며 공존하고자 하는 이 이론은 우리나라의 역사적, 사회문화적 특성을 바탕으로 한 사고 구조와 논리(cultural logics or reasoning)의 산물이라 하겠다. 본 연구를 통해 유방암의 진단과 치료는 문화적 특성에 상관없이 전 세계적으로 유사할지라도 그러한 경험이 개인에게 어떤 스트레스로 작용하여 대처하게 되는가의 차원은 그 개인이 속한 역사적, 사회문화적 맥락을 초월하여 생각할 수 없음을 알 수 있었다. More than 7,000 women are diagnosed with breast cancer each year in South Korea and many of them live long as cancer survivors. To date, no research has investigated Korean women’s coping process with breast cancer. This study thus was aimed to explore and describe the processes of coping with breast cancer among Korea women using a grounded theory methodology. Seventeen women aged between 30 and 63 with breast cancer who underwent cancer treatment in a rural cancer hospital participated in an individual face-to-face interview. All interviews were conducted in Korean, tape-recorded, transcribed, and analyzed according to the grounded methodology. Open coding, axial coding, and theoretical sampling of the categories were proceeded in data analysis. The overriding theme was “accepting and enduring the transient suffering with a lowered mind.” Two sub-themes were “clear one’s mind of distraction and live unboundedly as water flows down,” and “make up one’s mind to accepting reality.” The findings are mediated by Korean cultural concepts such as “lowering one’s mind” and “enduring life-suffering.” The findings highlight that a patient’ successful coping with breast cancer mandates the care provider’s culturally congruent awareness and understanding.

한국적 종양 전문간호사 교육과정의 발전 전략: 미국 교과 과정과의 비교분석

서은영(Suh Eunyoung) 대한종양간호학회 2006 Asian Oncology Nursing Vol.6 No.2

Purpose: With accumulated necessity to develop Advanced Practice Nursing (APN) in Korea, various types of Nurse Practitioner (NP) programs have been recently developed. Unlike the origin of the NP programs in the U.S., in which the lack of primary health care provider preceded the creation of NP education, NP programs in Korea are currently in an early stage in which the scope of practice and educational boundaries are still evolving. Just imitating American models may result in culturally inappropriate and practically non-feasible APN programs in Korea. This article was aimed to evaluate the top-ranked Oncology NP (ONP) programs in U.S. with those in Korea. Method: Using the Donabedian paradigm, the educational structure, process, and outcome were compared and contrasted between two countries. Results: The findings of this paper demonstrated that many aspects of structure of the Korean program are similar to those of the Americans with minor differences. Three strategies for future development of ONP program in Korea are suggested. Conclusion: Practical and feasible scope of practice for ONP in Korea should be determined. It needs to embrace every aspects of cancer experience. Also, nursing-oriented and culturally competent practice needs to be identified and incorporated into the ONP practice.

유방암 환자의 치료 전 경험

서은영(Suh Eunyoung E),박연환(Park Yeon-Hwan),김성재(Kim Sungjae) 기본간호학회 2008 기본간호학회지 Vol.15 No.4

Purpose: To date most research related to patients with breast cancer has discriminately investigated the status within or after the treatment although the patients demand holistic nursing care from the time of diagnosis. Thus, the purpose of this study was to investigate the trajectory of breast cancer diagnosis and patients' experiences in the pre-treatment period. Method: This qualitative study used qualitative thematic analysis. Nineteen Korean women who were diagnosed with breast cancer within the last 6 month participated in the study. Individualized interviews were conducted with each participant in a cancer center in K city. The interviews were tape-recorded, transcribed, and analyzed using the thematic analysis process. Results: The overriding theme was “the scattered life in an unforeseen swirl”, which illustrates the participants' unexpected crisis with confusion and emotional distress. Two subthemes included “falling into an unavoidable journey”, and “staggering in a muddle with urgency”. The categories were “unexpected probability”, “nagging nodularity”, “ominous presentiment”, “emotional upheaval”, “bad thought intrusion”, and “a sense of urgency”. Conclusion: Patients in the pre-treatment period encountered utter emotional distress and a sense of urgency after being diagnosed breast cancer. Strategies to develop nursing care for patients in this period and nursing implications are discussed.

의류 상품평 텍스트에 나타난 ‘좋다’ 구문의 의미와 극성 연구

서은영 ( Seo Eunyoung ) 연세대학교 언어정보연구원(구 연세대학교 언어정보개발원) 2018 언어사실과 관점 Vol.45 No.-

This study aims to assess the meaning and polarity of ‘johta’ constructions as occurring in clothing product reviews. Twelve types of constructions were identified and analyzed: -i johta, -ko johta, (N-i) johta, -ase johta, -ki(ey) johta, -myen johta, -ni(kka) johta, -ato johta, -nun key johta, -nuntey johta, -konun johta, -ciman johta. Each construction has its own particular meaning, which is closely linked to the semantic function of the connective ending that partly composes the construction. Findings reveal that ‘johta’ constructions in clothing product reviews are not always used to convey an ‘evaluation’ but can also express ‘advice’, ‘wish’, ‘request’ depending on the construction. Moreover, the polarity of each construction was identified based on the analysis of the examples extracted from the Clothing Product Review Corpus. As a result, most ‘johta’ constructions indicate a [+positive] polarity; nevertheless, the construction ‘-myen johta’ tends to be [-positive] while the construction ‘-konun johta’ always occur with both negative and positive evaluations.

조사 ‘의’의 장르별 분포 특성 - ‘N1의 N2’ 구성을 중심으로 -

서은영 ( Seo Eunyoung ) 연세대학교 언어정보연구원 2022 언어사실과 관점 Vol.57 No.-

The purpose of this study is to find out the distributional properties of case marker ‘uy’ by genre, focusing on the construction of the noun phrase ‘N1-uy N2.’ For this, nouns preceding and following ‘uy’ were classified into ‘the noun for a person,’ ‘the noun for a thing,’ ‘the noun for an event,’ ‘the noun for a state,’ ‘the noun for an abstract object,’ and ‘the noun for a location.’ And the distribution of each nominal type and differences in the use of ‘N1-uy N2’ construction in novels, newspapers, and academic articles were examined. As a result, it was found that the noun for a person accounted for the largest portion for the position of N1 in novels, the noun for a thing in newspapers, and the noun for an abstract object in academic articles, respectively. At the position of N2, the noun for a thing was most frequently found in novels and the noun for an abstract object in newspapers and academic articles, respectively. Lastly, to look at the ‘N1-uy N2’ construction, the construction of ‘[the noun for a person]-uy [the noun for a thing]’ was found to be used most in novels, the construction of ‘[the noun for a thing]-uy [the noun for a thing]’ in newspapers, and the construction of ‘[the noun for an abstract object]-uy [the noun for an abstract object]’ in academic articles, respectively. Besides, it was found that characteristic figures of speech or idiomatic expressions were used according to genres. This reveals that the distribution of case marker ‘uy’ differs according to the genres of texts, and shows that grammatical description considering genres from the aspect of language use is necessary since this distributional difference can be explained by linguistic tendencies.
