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.

Carbon-encapsulated Ni catalysts are synthesized by an electrical explosion of wires (EEW) method and applied for CO₂ methanation. We find that the presence of carbon shell on Ni nanoparticles as catalyst can positively affect CO₂ methanation reaction. Ni@5C that is produced under 5 % CH₄ 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 CO₂ 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.

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.

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%.

Protein phosphorylation is one of most important post-translational modifications (PTMs) and plays an important role in regulation of protein function. Here we develop a method for a global identification of phosphopeptides and phosphorylation sites using nano-LC MS/MS. We compared two separation methods, C4 and strong cation ion exchange (SCX). Before phosphopeptides enrichment with $TiO_2$, total proteins from Rat 1 cells have been separated using C4 column or tryptic peptides of proteins from the cells have been separated using SCX column. Finally, we have detected 52 phosphorylation sites on 41 proteins from SCX method and 375 phosphorylation sites on 252 proteins from C4 method, and determined the function and localization of identified phosphoproteins using DAVID software. In particular, we showed new phosphorylation sites from membrane proteins related to various cell signaling mechanisms. This method may contribute to study global signal networks induced by various signals including ligands and drugs.

Introduction Urticaria is widely spread disease. About 15-20 $\%$ of population has experienced at least once in a life time. The etiology of urticaria is uncertain till now, and the affcting factors are various chemical material, physical factors, alcohol, fever, exercise, and hormone, etc. The symptoms of urticaria are small or large wheal-erythema reaction and itching or tingling sense. Cause there is no probe to detect the urticaria clearly, the treatment of urticaria is symptomatic. And mostly urticaria can be chronic and very hard to treat it fundamentally. Nowadays, many trials to treat the urticaria in oriental medical way show good curability. In this paper I'd like to report the treatment rate and degree of urticaria patients mostly using anti-histamine medication. Subjects From the outpatients who visited Korean Hospital of Kyunghee Kangnam during 2000-4 and 2002-1, the 36 chronic urticaria patients, at least more than 4 weeks from onset and 2weeks of treatment period, were chosen. Methods I evaluated the results of treatment with the following scale. Very Good: The all symptoms are clearly disappeared or one third of symptoms remain and sometimes eruption is appeared. Good: Half of the symptoms are improved but most of symptoms remain. No Change: No change appears before and after treatment. Worse: The degree and duration of eruption get worse than pre-treatment state. Results For Acupuncture treatment, I chose the several Acu points like Hapgok(합곡), Taichung(대충), Gokji(곡지), Yanggok(양곡), Yanggea(양계), and lmeup(족임읍), and usually lasted it 15 minutes. With the acupuncture treatment and herb medicine, 2-3 times a week, the patients whose treatment period was 2 to 4 weeks were 17(47.2$\%$), 4 to 8 weeks were 11(30.5$\%$), 8 to 12 weeks were 3(8.3$\%$), 12 to 16 weeks were 3(8.3$\%$), longer than 16 weeks were 2(5.5$\%$) Collecting the statistics of the frequency of prescripted herb medicine, Hyangsosan(향소산) was prescripted 21 times(58.3$\%$), Hyangsapyungwisan(향사평위산) was 15 times(41.6$\%$), Hwapisan(화피산) was 9 times(25$\%$), Yangwitang(양위탕) was 6 times(16.6$\%$), Bojungikkitang(보중익기탕가미) was 4 times(11.1$\%$), Yongdamsagantang (용담사간탕가미) was 4 times(11.1$\%$). The result of the treatments, evaluating with mentioned rate scale, was 11 cases(30.5$\%$) were Very Good degree, 19 cases(52.7$\%$) were Good , 6 cases(16.6$\%$) were No Change. No cases were Worse degree. Conclusion According to this research, we could say that chronic urticaria can be treated with Oriental medical methods. But more precise probes in both Oriental and Western medicine to diagnose the chronic urticaria should be established and we need to make standards for testing and diagnosing the chronic urticaria.

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.

김혜정,Kim, Hye-Jeong 한국융합학회 2021 한국융합학회논문지 Vol.12 No.4

본 논문의 목적은 줌을 기반으로 학습용 앱 활용이 학습자들의 영어 성취도에 미치는 영향을 살펴보고 이를 통해 줌 기반의 학습용 앱을 활용한 영어 수업의 효율성을 고찰하고자 한다. 본 연구는 줌 기반 수업에서 English Central 앱을 활용하였으며 이를 통해 다양하면서도 학습자들의 참여를 유도하는 영어 활동을 수행하였다. 줌 기반의 EC 앱 활용 수업의 효율성을 파악하기 위해 1차와 2차 성취도 테스트, 개방형 설문조사를 실시하였다. 두 차례의 테스트 결과 줌 기반의 EC 앱 활용 수업은 학습자들의 영어 성취도에 긍정적인 영향을 미치는 것으로 나타났다. 설문 조사결과 학습자들은 줌 기반 수업과 EC 앱 활용에 대해 만족도가 높은 것으로 나타났다. 줌 기반 수업에 대한 만족의 이유는 "부족한 수업 내용 보완", "영어 연습", "실시간 소통과 의견 공유" 으로 나타났다. 학습용 앱 활용에 대해 만족하는 이유는 "지루하지 않음", "영어의 4기술 훈련", "즉각적인 피드백"으로 나타났다. 변화된 언택트 시대 교수자들은 변화된 환경에 맞는 변화된 수업 도구의 효율적 사용을 위해 노력해야 한다. This study examined how the use of learning apps in Zoom-based classes affects learners' English achievement and assessed the efficiency of app use in Zoom-based English classes. The study utilized the English Central (EC) app to induce learners to actively participate in zoom-based classes. To assess the app's efficiency, two rounds of achievement tests and an open-ended questionnaire were administered. The two tests showed that Zoom-based EC app utilization classes positively affected learners' English achievement and the questionnaire revealed that the learners were highly satisfied with using the EC app in Zoom-based classes. The participants praised this approach for "complementing insufficient class content" and facilitating "immediate feedback" (on the EC app), "English practice," and "real-time communication and sharing of opinions" (on Zoom-based classes), describing it as "not boring" and "4 skill training in English." Instructors should strive to efficiently use such new teaching tools in the evolving environment of the untact era.
