Objective: This study aims to analyze that specific prognostic factors such as Ki-67 value, histologic grade, pathology type, and cancer stage can affect controlled ovarian stimulation outcomes(COS) for fertility preservation in women with breast cancer. Methods: This retrospective cohort study included 92 patients with breast cancer aged 21-44 who underwent COS from August 2012 to April 2020, excluding patients with previous gonadotoxic therapy history. All COS cycles were conducted letrozole-combined random start GnRH antagonist protocol. COS outcomes were compared according to prognostic factors;Ki-67 (< 30% vs. ≥ 30%), histologic grade (low vs. high), and pathologic type (intraductal carcinoma(IDC) vs. triple-negative breast cancer(TNBC)), and cancer stage (early (I, II) vs. advanced (III, IV)). Multivariate analysis was also conducted to find any parameter that can impact over 10 mature oocytes acquisition. Results: Among the 92 patients, 42 were Ki-67≥30% compared to 49 of Ki-67<30%. The number of oocytes, and initial mature oocytes were comparable between Ki-67<30% and ≥30 group. The maturation rate was significantly higher in Ki-67≥30% group than Ki-67<30% group (57.4±36.8% vs. 44.8±28.3%, p=0.041). The same results were drawn when divided according to IDC or TNBC. The maturation rate was significantly higher in TNBC than the IDC group (73.0±17.6% vs. 47.0±28.1% p=0.001). However, the histologic grade or stage did not show any difference in COS outcomes between high and low grade or early and advanced stages. With multivariate analysis, age and AMH are parameters associated with the acquisition of over 10 mature oocytes (OR 0.863, 95% CI [0.755-0.987], OR 1.408, 95% CI [1.145-1.732], respectively). Conclusion: Either Ki-67 or pathologic type can be a potential reliable marker for predicting COS outcome, especially maturation rate. Further study with larger sample size with specific conditions is necessary to clarify the correlation between breast cancer prognostic factors and COS outcomes.

Possibility of Empowerment in The Surrendered by Chang-rae Lee

Seul Ki Lee Ewha Institute of English and American Studies 2022 Journal of English and American studies Vol.20 No.1

This paper supports the interpretation that the main characters in Chang-rae Lee’s The Surrendered find liberation in being surrendered. As a novel written by a recognized Korean-American writer about The Korean War, The Surrendered received many reviews concentrating on the author’s writing style and artistry. These early critics stated that the novel’s varying temporal and geographical shifts and the fact that the novel revolves around three different characters make the novel unnecessarily complex. In addition, the scholarly works that do analyze the novel concentrate on the trauma, disability, and post-traumatic stress disorder resulting from the violence. Although prior research touched upon the characters and the symbolism within the setting, I would like to do a more in depth analysis. I use the concept of “abjection” to analyze the symbolism of the three main characters: June, Hector, and Sylvia. All three characters have distinct individuals while also representing others who have survived the social situations they faced. Therefore, it is meaningful to analyze three characters and how they use their status as abjects to find a form of liberation and empowerment.

The Conjugated Double Bond of Coniferyl Aldehyde Is Essential for Heat Shock Factor 1 Mediated Cytotoprotection

Choi, Seul-Ki,Mun, Gil-Im,Choi, Eun,Kim, Seo-Young,Kwon, Youngjoo,Na, Younghwa,Lee, Yun-Sil American Society of Pharmacognosy 2017 Journal of natural products Vol.80 No.8

<P>Coniferyl aldehyde (1) is previously reported as a potent inducer of heat shock factor 1 (HSF1). Here, we further examined the active pharmacophore of 1 for activation of HSF1 using the derivatives coniferyl alcohol (2), 4-hydroxy-3-methoxyphenylpropanal (3), and 4-hydroxy-3-methoxyphenylpropanol (4). Both 1 and 2 resulted in increased survival days after a lethal radiation (IR) dose. The decrease in bone marrow (BM) cellularity and Ki67-positive BM cells by IR was also significantly restored by 1 or 2 in mice. These results suggested that the vinyl moiety of 1 and 2 is necessary for inducing HSF1, which may be useful for developing small molecules for cytoprotection of normal cells against damage by cytotoxic drugs and radiation.</P>

Objective : The purpose of this study was to investigate attitude of grade-schoolers toward children with disabilities. Methods : The subjects of this study were grade-schoolers who have not received an inclusive education in Gim-hae. The study was surveyed from October second to 17th in 2008. The survey was categorized into three parts; comradeship, activity, and study. Each part of the survey consists of 10 questions. Data were analyzed by SPSS (version 12.0). Results : The results were as follows; First, the attitude of girls toward disabled students was non-significant compared to boys. Second, the order of attitude degree in grade of students was 4, 6, and 5. The attitude toward children with disabilities showed statistically significant difference according to grade(F=3.546, p<0.05). Third, the attitude of students who have experience of contact with people with disabilities was non-significant compared to non-experienced students. Conclusion : In conclusion, therefore peer groups in lower class levels showed more positive attitude toward the children with disabilities. The result will be useful information for understanding disabled children and making positive attitude. Also it is expected that occupational therapists help disabled children to participate in school life successfully using these information.

ALEP (acute localized exanthematous pustulosis): a rare variant of AGEP (acute generalized exanthematous pustulosis)

( Seul Ki Lim ),( Myung Im ),( Young Lee ),( Jeung Hoon Lee ),( Young Joon Seo ) 대한피부과학회 2015 대한피부과학회 학술발표대회집 Vol.67 No.1

Acute localized exanthematous pustulosis (ALEP) is a variant of acute generalized exanthematous pustulosis (AGEP). The epidemiology of ALEP is not established. In worldwide, only 21 cases have been reported in the literature. The most common localized site is face and most of cases were induced by systemically administered drugs. A 47-year-old male visited our clinic for an acute outbreak of pustule with underlying erythematous base affecting face and neck. He had itching and burning sensation on this lesions. There was no history of taking medicine. However after working in greenhouse, the clinical symptoms have been worsened. This history suggested that agricultural pesticides might be the cause. On histopathological study, it showed subcorneal pustule with perivascular lymphocyte and neutrophil infiltration. The pustular lesions were resolved in 5 days by methylprednisolone treatment. Here, we report the ALEP patient who has localized pustule on face and neck. Though it is rare variant of AGEP, it should be regarded in noninfectious multiple pustular lesions.

Ki-Sub Kim,Seul Bee Lee,Hoon Sik Kim,Youngwoo Lee,Kwangsoo Kwack,Hyunjoo Lee 한국공업화학회 2009 Journal of Industrial and Engineering Chemistry Vol.15 No.5

New polymer-ionic liquid-lithium salt gel electrolytes (PILGEs) were prepared using poly(vinylidenefluoride)-hexafluoropropylene copolymer (PVdF(HFP)), methyl N-methylpyrrolidinium-N-acetate trifluoromethanesulfonimide ([MMEPyr][TFSI]), and lithium trifluoromethanesulfonylimide (LiTFSI) in order to investigate the effects of ionic liquids containing an ester group on the electrochemical properties of polymer gel electrolytes. Free standing ionic gels consisting of PVdF(HFP), [MMEPyr][TFSI], and LiTFSI were prepared in a range of weight ratio of polymer/[MMEPyr][TFSI]/LiTFSI = 1/2/0.1 1. Ionic conductivities for the prepared PILGEs were measured with changing temperature and weight ratio of LiTFSI and the obtained values were found to be reasonable (104 S ㎝1) over the operating temperatures.

Clear cell papulosis: one of the hypopigmentation disorders in early childhood

( Seul Ki Lim ),( Hae Eul Lee ),( Myung Im ),( Young Joon Seo ),( Jeung Hoon Lee ),( Young Lee ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.1

Clear cell papulosis (CCP) is a rare condition in early childhood with hypopigmented macules or palpable papules on pubic region, lower abdomen, and anterior trunk. A 2-year-old girl visited our clinic for asymptomatic hypopigmented macules and flat topped papules on the inguinal area, suprapubic area and anterior trunk. The patient had no history of trauma or inflammation. Histopathological examination showed the clear cells which were round and oval shape with abundant pale cytoplasm. These cells were mostly located in basal layers and occasionally in spinous layers. Fontana-Masson stain showed decreased pigmentation compared with adjacent normal skin. The patient was diagnosed as CCP with clinical manifestation and characteristic histologic findings. CCP often can be confused with tinea versicolor, anectoderma, idiopathic guttate hypomelanosis or chicken pox scars. Though it is a rare disease entity, CCP should be kept in mind as one of the differential diagnoses of localized hypopigmented macules on trunk in early childhood.

Effects of Intrinsic and Extrinsic Motivation Factors on BIM Acceptance

Lee, Seul Ki,Yu, Jung-Ho The Korean Institute of Building Construction 2013 한국건축시공학회지 Vol.13 No.3

Although many researchers and practitioners are in agreement about the potential applicability and benefit of BIM in construction, it is still unclear why BIM is adopted, and what factors enhance the adoption and implementation of BIM. As such, the mechanism of BIM acceptance and use remains in question. Therefore, this paper aims to identify the key factors affecting the acceptance of BIM in construction organizations, and to analyze the effect of intrinsic and extrinsic motivation factors on BIM acceptance. The key factors in BIM acceptance are identified through a literature review in TAM (Davis 1989) and related theories, and consolidated by interviews and pilot studies with professionals in the construction industry. Based on the factors, a questionnaire was designed and sent out to a total of 114 construction organizations in Korea, such as contractors, architects, and engineers. Using SPSS 12.0, the data was analyzed to determine the relationship between intrinsic and extrinsic motivation factors and BIM acceptance through multiple regression analysis. These findings will clarify what the highly prioritized factors are, and can also be used in an assessment tool for the performance of BIM utilization.
