김경아,김경아 복식문화학회 2019 복식문화연구 Vol.27 No.5

Oversized fashion is again in the spotlight due to the influence of retro fashion. This has created new fashion trends with methods different from those of the past. This analysis examines recent trends by sorting these looks according to new and different methods of judging their appearance. A new categorization of the oversized look and its configurations has been created, one which separates “big” looks, partial changes, and layered looks. This research was based on historical review and previous studies. Three thousand one hundred thirty-six photos of oversized looks that have appeared in collections over the past five years were gathered, and their appearance was categorized according to type. The categorization results showed that big looks (55.1%) were most prevalent, followed by partial alterations (36.35%), and layered looks (8.45%). In comparison to prior oversized clothing production, new permutations of the “Big” look expanded the silhouettes of torso, shoulders, neckline and collar. Partial changes have expanded from the broadened shoulders of the 1980s. Today these styles expand the shoulders and armholes vertically or horizontally, which dramatically exaggerates the sleeves and collar. The layered look no longer simply features overlapping layers but takes the form of over-layering through cuts and insertions. Through such analysis it is clear that modern oversized looks break away from the simple expanded forms and production methods of the past. They now attempt to realize an exaggerated beauty of form regarding each clothing component and also maximize decorative effects through innovative drafting or sewing methods.

Facile Preparation of Silver Nanoparticles and Application to Silver Coating Using Latent Reductant from a Silver Carbamate Complex

김경아,차재령,공명선 대한화학회 2013 Bulletin of the Korean Chemical Society Vol.34 No.2

A low temperature (65 oC) thermal deposition process was developed for depositing a silver coating on thermally sensitive polymeric substrates. This low temperature deposition was achieved by chemical reduction of a silver alkylcarbamate complex with latent reducing agent. The effects of acetol as a latent reducing agent for the silver 2-ethylhexylcarbamate (Ag-EHCB) complex and their blend solutions were investigated in terms of reducing mechanism, and the size and shape of silver nanoparticles (Ag-NPs) as a function of reduced temperature and time, and PVP stabilizer concentration were determined. Low temperature deposition was achieved by combining chemical reduction with thermal heating at 65 oC. A range of polymer film, sheet and molding product was coated with silver at thicknesses of 100 nm. The effect of process parameters and heat treatment on the properties of silver coatings was investigated.

김경아 한국시민윤리학회 2016 한국시민윤리학회보 Vol.29 No.2

본 연구에서는 여성의 경력단절 원인과 현황 그리고 재취업 과정에서 나타나는 문제점을 토대로 경력단절여성의 재취업 활성화 방안에 대해 연구했다. 여성의 경력단절 주요 원인은 결혼, 임신과 출산, 건강 그리고 가사(집안 일) 때문이었다. 그 외 다른 직장으로 이직 또는 창업, 소득과 보수가 적어서 그리고 근무환경 등 구조적 문 제점도 있었다. 그리고 경력단절 여성의 고학력화 현상과 시민운동의 발달, 자녀수의 감소, 여성의 교육기회와 사회참여확대가 재취업의 동기가 되었다. 또한 경제활동과 가정이라는 한 정된 영역에서 생활하면서 단절감과 소외감을 느껴, 경력단절 여성 스스로 자아를 찾고 사회 에 소속감에 대한 욕구가 생겨나면서 재취업에 동기가 생겼다. 따라서 이러한 연구결과를 토대로 경력단절 여성의 재취업의 활성화 방안을 모색했다. 첫째, 임신과 출산, 자녀양육이라는 점을 고려해 ‘양질의 시간제 일자리 확대가 필요하다. 둘째, ‘믿고 맡길 수 있는 보육시설 확충이 필요하다. 셋째, 여성들에 대해 갖고 있는 성, 연 령 차별 등의 사회 구조적 인식과 문제점도 고쳐야 할 것이다. 넷째, 자아실현에 초점을 맞춘 다양한 교육프로그램 그리고 여성능력 개발 프로그램이 필요하다. 다섯째, 경력단절 여성의 재취업을 지원해 줄 수 있는 다양한 직업경력, 설계, 취업상담과 취업정보 획득을 위한 다양 한 채널이 구축되어야 할 것이다. The purpose of this study is to investigate the causes and Re-employment of Career interrupted Women. The main reasons for Career interrupted Women were marriage, pregnancy and childbirth, health and housework. There were also structural problems such as job turnover or start-up, income and pay, and working environment. And Career interrupted Women have a desire to work due to the effect of higher educational attainment, the development of civil movements, the decrease of the number of children, the educational opportunities of women and the increase of social participation. Also while living in a limited area of economic activity and family, she feeling disconnection and alienation, she has a desire to work. Therefore, based on the results of this study, we sought to the reemployment of Career interrupted Women First, considering the fact that pregnancy, childbirth and child-rearing, we should quality-based part-time jobs expanded. Second, it is necessary to expand child-care facilities that can be trusted. Third, social structure recognition and problems such as sex discrimination and age discrimination for women should be improved. Fourth, a variety of educational programs focusing on self-realization and women’s skills development programs are needed. Fifth, various channels should be constructed for job career, design, career counseling and job information acquisition for the re-employment of career interrupted women.

Preparation of Zinc Oxide Nanoparticles at Low Temperature Using New Organometallic Zinc Carbamate Precursor

김경아,차재령,윤상우,공명선 대한화학회 2015 Bulletin of the Korean Chemical Society Vol.36 No.5

Zinc oxide nanoparticles (ZnO NPs) were synthesized in 2-methoxyethanol without assistance of base, surfactant, template, etc., at relatively low temperature of 125 °C, by a single-step thermolysis. Thermolysis of Zn(IBC)2 led to the formation of almost pure ZnO NPs of various shapes. Transmission electron microscope (TEM) images showed that oleic acid–stabilized ZnO NPs with diameters of 10–20 nm were well dispersed in organic solvent. Resulting ZnO was characterized by UV–vis spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, X-ray powder diffraction, scanning electron microscopy, and high-resolution TEM. Room temperature photoluminescence (PL) spectra of ZnO NPs annealed at different temperatures showed different emission peaks in the range of 400–700 nm. The ZnO NPs prepared at 125 °C in air caused a further shift of the defect-related PL maximum toward the lower energy range (red-light emission) in comparison with the one prepared at 125 °C in 2-methoxyethanol.

Preparation of ZnO2 Nanoparticles Using Organometallic Zinc(II) Isobutylcarbamate in Organic Solvent

김경아,차재령,공명선,김종규 대한화학회 2014 Bulletin of the Korean Chemical Society Vol.35 No.2

Zinc peroxide nanoparticles (ZnO2 NPs) were prepared by reacting zinc(II) isobutylcarbamate, as an organometallic precursor, with hydrogen peroxide (H2O2) at 60 °C. Polyethylene glycol and polyvinylpyrrolidone were used as stabilizers, which suppressed aggregation of the ZnO2 NPs. Conditions such as concentrations of H2O2 and the stabilizer were systemically controlled to determine their effect on the formation of nano-sized ZnO2 NPs. The formation of stable ZnO2 NPs was confirmed by UV-vis, Raman spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and X-ray diffraction. The TEM images revealed that polyvinylpyrrolidone-stabilized ZnO2 NPs (diameter, 10–30 nm) were well dispersed in the organic solvent. Quite pure ZnO NPs were obtained from the peroxide powder by simple heat treatment of ZnO2. The transition temperature of 170 oC was determined by differential scanning calorimetry.

오존 기상처리방법에 의한 비스코스 레이온의 탈색효과

김경아,이문수,Kim, Gyoung-A,Lee, Mun-Soo 배재대학교 자연과학연구소 1998 自然科學論文集 Vol.10 No.1

We studied on the decoloring effect of viscose rayon by vapor type ozone processing using ozone's strong oxidation. When ozone is generated, it becomes high concentration in vapor state, but in the insolving process with water, there are a lot of lose of ozone. As a result, a study using ozone in vapor-high concentration state is needed. So, in this paper, vapor type ozone processing is used unlike previous ozone treatment method-an aqueous solution method-to get a good effect from shortening the processing time. When vapor type ozone processing was directly treated to fabrics, high concentration ozone was generated then in a short time oxidized a dye existed in fabrics and finally decolored it. As vapor type ozone did not directly response to an organic dye, viscose rayon's decolorization was to be studied by changing pick up ratio(60%, 50%, 40%, 30%, 20%) using water as a medium. When pick up ratio of water was 40%, fabric's whiteness was improved but tensile strength and elongation were reduced. So 60 minutes was assumed as the most adjust time to minimize the reduction of fabric's tensile strength and elongation moreover of maximize the improvement of whiteness.

글로벌 경제위기 이후 국내금융시장의 변화추세와 정책방안

김경아 한국재정학회(구 한국재정·공공경제학회) 2009 한국재정학회 학술대회 논문집 Vol.2009 No.3

본 연구에서는 첫째, 주요 금융위기의 역사, 글로벌 금융위기 배경 및 글로벌 금융위기의 금융시장에 대한 영향에 대해서 살펴보았다. 다음으로, 국내 금융시장의 주요 변수들에 대한 GARCH(1,1)추정을 수행하여 실증분석 결과를 제시하고, 글로벌 금융위기가 국내 금융시장의 변동성에 미친 영향에 대해 논의하였으며, 셋째, 글로벌 금융위기에 대한 각국의 정책대응 현황 및 향후과제에 대해서 논의하였다.국내 금융시장의 주요 변수들에 대한 GARCH(1,1) 추정 결과, 국내 주요금리들의 경우 약간이차이는 있으나 전반적으로 현재의 변동성 충격이 다음기의 변동성에 미치는 영향을 나타내는 α1의값은 주식시장 및 외환시장보다 상대적으로 높게 나타난 반면, 의β1 값은 주식시장 및 외환시장보다상대적으로 낮게 나타났다. 시장의 위험을 의미하는 변동성의 크기와 지속적인 발생은 전체기간에걸쳐 국내 주식시장이 가장 높게 나타났으며, 국내 주요금리들의 경우 가장 낮게 나타났다. 기간별세부적 추정결과, 최근의 2007년 글로벌 금융위기 기간보다 지난 1997년 외환위기 기간 동안 변동성의 크기가 더 크고 좀 더 길게 발생한 것으로 나타났다.2009년 현재 각국의 지속적인 금융시장안정화정책으로 세계 및 국내 금융시장은 이전보다 안정을 되찾고 있다. 그러나 각국의 실물경제에 있어서의 생산 감소 및 고용악화는 여전히 잔재해 있으며, 금융시장의 완전한 회복과 위험감소는 아직도 요원한 상태이다. 따라서 현 시점에서 금융시장의장기적 안정과 회복을 실현하기 위해서는 정책당국자, 신용평가자 및 국제기구들의 지속적 시장안정화 정책 노력이 필요하다고 보인다.
