        야담에 나타난 여성의 우정 실현의 두 양상

        김혜정(Kim Hye-Jeong) 돈암어문학회 2005 돈암어문학 Vol.- No.18

        The study purposes to discuss the realization type of woman's friendship through the yadam in the period of Chosun(朝鮮) dynasty. The works of discussion are NAK HA YU SAENG(洛下柳生), MAE HEON(梅軒), which are composed mainly of woman' friendship.<br/> In spite of different social position, three women with a same birthy day in NAK HA YU SAENG made friends with each other from childhood. After growing up, as one of them married to a man, the others sought for to her to live together and marry her husband. On the above works, woman's friendship realized their friendship through the polygyny legalized in the Chosun society.<br/> The subject of MAE HEON is the friendship of two woman writers. One died of miscarriage, the other took her own life to follow with her friend. On the point of women's early death, not only the woman's friendship but also their activity of learning and art seems to be refused from the Chosun society.<br/> The subject of woman's friendship is very rare, taboo in Korea classic literature including yadam, because Chosun dynasty was a androcentric society.<br/> In conclusion, the discussion on the above two works, woman's friendship in the yadam has to choose alternatively polygyny or tragic death. But none of two ways is the true realization of woman's friendship.

        탄소층으로 캡슐화된 Ni나노입자 촉매의 CO<sub>2</sub> 메탄화 반응

        김혜정,김승보,김동현,윤재랑,김민재,전상구,이경자,이규복,Kim, Hye Jeong,Kim, Seung Bo,Kim, Dong Hyun,Youn, Jae-Rang,Kim, Min-Jae,Jeon, Sang Goo,Lee, Gyoung-Ja,Lee, Kyubock 한국재료학회 2021 한국재료학회지 Vol.31 No.9

        Carbon-encapsulated Ni catalysts are synthesized by an electrical explosion of wires (EEW) method and applied for CO<sub>2</sub> methanation. We find that the presence of carbon shell on Ni nanoparticles as catalyst can positively affect CO<sub>2</sub> methanation reaction. Ni@5C that is produced under 5 % CH<sub>4</sub> partial pressure in Ar gas has highest conversions of 68 % at 350 ℃ and 70 % at 400 ℃, which are 73 and 75 % of the thermodynamic equilibrium conversion, respectively. The catalyst of Ni@10C with thicker carbon layer shows much reduced activity. The EEW-produced Ni catalysts with low specific surface area outperform Ni catalysts with high surface area synthesized by solution-based precipitation methods. Our finding in this study shows the possibility of utilizing carbon-encapsulated metal catalysts for heterogeneous catalysis reaction including CO<sub>2</sub> methanation. Furthermore, EEW, which is a highly promising method for massive production of metal nanoparticles, can be applied for various catalysis system, requiring scaled-up synthesis of catalysts.

        시뮬레이션을 활용한 폰카메라 렌즈모듈 부품용 사출금형개발

        김혜정,김재훈,김영규,송준엽,문덕희,Kim, Hye Jeong,Kim, Jae Hoon,Kim, Yeong Gyoo,Song, Jun Yeob,Moon, Dug Hee 한국시뮬레이션학회 2013 한국시뮬레이션학회 논문지 Vol.22 No.4

        휴대폰 시장의 확산으로 인하여 휴대폰에 장착되는 카메라 렌즈모듈의 수요도 급증하고 있다. 렌즈모듈 부품의 경우 해상도의 증가에 따른 사출공정의 품질보증과 원가절감이라는 두 가지 목표를 달성해야 한다. 따라서 본 논문에서는 더블카세트 방식의 금형구조를 이용하여 경통과 쉴드 두 종류의 제품을 개발하기 위해 시뮬레이션을 활용한 사례를 소개한다. 개발과정에서 두 종류의 시뮬레이션 기술을 활용하였는데, 첫 번째는 금형 설계단계에서 사출품의 성형성을 분석하기 위한 시뮬레이션(일명 Computer Aided Engineering)을 Mold Flow$^{TM}$를 사용하여 수행하였고, 두 번째는 사출기에 금형을 장착한 후 제품이 사출되어 취출하는 동작을 분석하기 위한 동작 시뮬레이션을 DPM Assembly$^{TM}$를 이용하여 수행하였다. 개발 결과 기존 방식에 비해 제품의 생산성이 300% 이상 증가하는 효과를 얻었다. The demand of a camera-lens-module which is installed in mobile phone has been increased explosively as the increase of mobile phone market. Recently, two missions are given to the parts manufacturer of lens module, and they are how to keep the quality of injection moulding process as the increase of resolution, and how to decrease manufacturing cost. In this paper, a simulation study is introduced which is used for developing barrel and shield considering the double-cassette type of mould. At first, the simulation for injection process using Mold Flow$^{TM}$ is applied in the phase of mould design, and mechanical simulation using DPM Assembly$^{TM}$ is applied for collision detection between picking robot and mould. As a result, the productivity increased more than 300%.

        DOE를 적용한 카메라폰 모듈용 비구면 Glass 렌즈의 가압성형조건 연구

        김혜정,차두환,이준기,김상석,김정호,Kim, Hye-Jeong,Cha, Du-Hwan,Lee, Jun-Key,Kim, Sang-Suk,Kim, Jeong-Ho 한국전기전자재료학회 2007 전기전자재료학회논문지 Vol.20 No.8

        This study investigated the pressing conditions in the molding of aspheric glass lenses for the mega pixel phone camera module using the DOE method. Tungsten carbide (WC; Japan, Everloy Co., 002K),which contained 0.5 w% cobalt (Co), was used to build the mold. The mold surface was ultra-precision ground and polished, and its form accuracy (PV) was 0.85um in aspheric surface. We selected four factors, pressing temperature, force and time of first step, and force of second step, respectively, as the parameters of the pressing process. in order to reduce the number of experiments, we applied fractional factorial design considering the main effects and two-way interactions. The analysis results indicate that the only two main effects, the pressing temperature and the time of pressing step 1, are available for the form accuracy (PV) of the molded lens. The analysis results indicated that the best combination of the factors for lowering the form accuracy(PV) value of molded lens was to have them at their low levels.

        ${\apha}$-Casein의 인산화 위치 규명을 위한 티타늄 다이옥사이드($TiO_2$) 방법의 최적화

        김혜정,박자혜,백문창,Kim, Hye-Jeong,Park, Ja-Hye,Baek, Moon-Chang 대한약학회 2008 약학회지 Vol.52 No.5

        Phosphorylation plays the most important role in cell signaling mechanism. Various methods to identify the phosphorylation sites of proteins using tandem mass spectrometry (MS/MS) have been reported recently. Furthermore, the enrichment strategy such as Titanium dioxide ($TiO_2$) method should be combined with MS/MS analysis to effectively identify phosphorylation sites. It is necessary to optimize phosphopeptide-enrichment strategy, $TiO_2$ method in this study, due to the low amount of phosphorylated form followed by analyzing them by MS/MS. To evaluate the several conditions to enrich phosphopeptides using $TiO_2$ method, we used ${\apha}$-casein as a standard phosphoprotein and analyzed a representative phosphopeptide (VPQLEIVPNpSAEER) peak of MS spectrum. Batch is better than column method for binding and 300 g/l DHB in loading buffer is better than lower concentration of DHB. 3% TFA and pH 10.5 shows high efficiency of phosphopeptide-enrichment for washing and elution steps, respectively. Finally we identified various efficient conditions of phosphopeptide-enrichment method using $TiO_2$. This optimized method would assist in reliable identifying thousands of phosphorylation sites existed in low abundance from various complex proteins.

        급성 화폐상 습진을 동반한 아토피 피부염 환자의 한방치험 1례

        김혜정,Kim, Hye-Jeong 대한한방안이비인후피부과학회 2001 한방안이비인후피부과학회지 Vol.14 No.1

        Nummular eczema is well-shaped, coin-like lesion. Usually it is surrounded by the papules and vesicles, and is likely to be the impetigo. It's said that nummular eczema is combined with atopic dermititis, contact dermatitis, bacterial infection and so on. Recently, we experienced a nummular eczema with impetigo and that was successfully treated by the herb-medication and the ceramic resonance therapy. The medications taken by the patient were yunwhasagnatang and gamisopungsan which is used to treat allergic disease and make immune system be strong. The former effects the liver to be cool down and healthy and it also has anti-imflamatory reactions like the corticosteroid hormone. Ceramic resonance therapy utilises irradiation within the frequency range of the radiation emitted by the human body. So we report this case with a brief review of the oriental medical and medical literatures.

        굴삭기 부품 용접 자동화라인의 셀생산방식 적용을 위한 시뮬레이션 연구

        김혜정,이승우,문덕희,Kim, Hye Jeong,Lee, Seung Woo,Moon, Dug Hee 한국시뮬레이션학회 2013 한국시뮬레이션학회 논문지 Vol.22 No.2

        다품종 소량생산이 보편화 되면서 하나의 생산라인에서 여러 종류의 제품을 교대로 생산하는 혼류생산방식이 보편화 되었다. 하지만 흐름라인 방식의 혼류생산에서는 필연적으로 작업장 간의 공정시간 불균형이 존재한다. 따라서 이러한 공정불균형에 의한 대기의 낭비를 최소화하기 위하여 기존의 흐름생산방식에서 셀생산방식으로 전환하는 시도가 빈번하게 발생한다. 본 논문에서는 굴삭기 부품을 생산하는 혼류흐름라인 방식의 자동화 로봇 용접라인을 FMC 개념의 직선형 셀방식으로 전환하는 과정에서 타당성 검토를 위해 시뮬레이션을 수행한 사례연구 결과를 소개한다. 분석결과 26.7%의 생산량 증가와 55% 이상의 리드타임 감소효과가 예상되었다. 또한 향후 제품 생산비율의 변화에 따른 민감도분석을 수행하였다. Mixed model production system means that various products are manufactured alternately in a line, and it has become a popular system in the era of multi-product small-quantity production. However, in the mixed model production system using flow line, the unbalance among stations is not inevitable because the workloads of stations cannot be the same. Thus, flow line system has been replaced to cellular manufacturing system for reducing the loss of waiting due to the unbalance of stations. In this paper, we introduce the simulation case study of an automated welding line which produces the parts of excavator. The factory has considered replacing the mixed model flow line to the cellular manufacturing system based on FMC concept. The increase of production quantity is estimated about 26.7%, and the lead time is reduced more than 55%. Furthermore sensitivity analyses are conducted considering the changes of product-mix.
