Ji-Seung crafts(Paper string crafts) is traditional handicraft of Korea, which is to strip and twist Hanji(Korean traditional paper) to make goods such as straw mat, box of wedding gifts(Ham), bottle, basket, bag, etc. Ji-Seung crafts requires considerable time and concentration due to process in addition to weaving, which is to prepare for certain amount of raw materials by twisting Hanji string with hand. Because of the arduous process, it has been difficult to popularize Ji-Seung crafts even though it is an outstanding traditional handicrafts. On the other hand, the elaboration could also be a strength to aim for high value added products by recognizing Ji-Seung crafts as high-quality handicrafts. Dress made by Ji-Seung crafts, ‘The Life & Foam of an Indigo blue Sea’ is a piece of work created by traditional Ji-Seung crafts, which was tailored by three-dimensional structure to be actually wearable. In an attempt to find proper exhibition place to maximize the visual effect when the model walks in the dress, it was decided to submit for WOW(World of WearableArt Award) Show in New Zealand. It is an international art fashion show held annually in New Zealand and it is known for lively and brilliant imagination by exhibiting wearable work piece without being limited in raw materials. In was first started in 1987 at Nelson, New Zealand and since 2005, it has been convened in Wellington, the capital of New Zealand. In WOW Show in 2006, 380 pieces were submitted from 90 nations and among them, 154 pieces were selected for the main stage. Dress made by Ji-Seung crafts, ‘The Life & Foam of an Indigo blue Sea’ was awarded with the 1st prize in international competition. The purpose of this study is to share my experience to propose the possibility for young craftsmen to appear on the international stage and find the future of new traditional handicrafts.

This study analyzes the common space of the high schools before and after the decade of 2009 which starts Subject-centered clusters school plan, and proposes the direction of common space planning for the future. Based on the floor plans of high schools awarded as excellent school facilities every year, first, types and numbers of common space, second, area ratio between common space and program space and also moving space and staying space, third, space connections were analyzed for tracking the change of the relationship between common, staying and program spaces. The study results demonstrated that types, numbers and area ratio of the common space were increased as the years go on. Especially, the area ratio of staying space was dramatically increased after 2009 and this result was caused by the home-base, alcove space, and hall that were adopted for subject-centered clusters planning after 2009. Connecting diagram of staying area and program spaces also shows the spaces related to staying area were changed from a classrooms and administrative office etc. to a library, gym, and seminar rooms etc. In case of staying area, it would have a value as a common space for various student activities such as group activities, meetings, and multi-uses. Because student activities would be changed and encouraged depending on the location, sizes and program spaces around staying area, it should be emphasized that the planning for staying area is critical for future school design.

신지은,오윤식,임동훈,Shin, Ji Eun,Oh, Yoon Sik,Lim, Dong Hoon 한국데이터정보과학회 2016 한국데이터정보과학회지 Vol.27 No.3

RHadoop is a collection of R packages that allow users to manage and analyze data with Hadoop. In this paper, we implement K-Means algorithm based on MapReduce framework with RHadoop to make the clustering method applicable to large scale data. The main idea introduces a combiner as a function of our map output to decrease the amount of data needed to be processed by reducers. We showed that our K-Means algorithm using RHadoop with combiner was faster than regular algorithm without combiner as the size of data set increases. We also implemented Elbow method with MapReduce for finding the optimum number of clusters for K-Means clustering on large dataset. Comparison with our MapReduce implementation of Elbow method and classical kmeans() in R with small data showed similar results.

추정 BER을 이용한 다중 밴드 전송 기법의 가중치 알고리즘 연구

신지은,정현우,정지원,Shin, Ji-Eun,Jeong, Hyun-Woo,Jung, Ji-Won 한국음향학회 2021 한국음향학회지 Vol.40 No.4

In underwater communications, to compensate performance degradation induced from rapidly changing channel transfer characteristic, multi-band communication method which allocate the same data to different frequency bands is used. However, the multi-band configuration may have worse performance than the single-band one because performance degradation in a particular band affects the output from the entire bands. This problem can be solved through a receiving end that analyzes error rates of each band, sets threshold values and allocates lower weights to inferior bands. Therefore, this paper proposed a weighting algorithm based on estimated Bit Error Rate (BER) which analyzes reliability of received data based on the performance difference between demodulated and decoded data. Employing turbo codes with coding rate of 1/3, we evaluate the performance of the proposed weighted multi-band transmission model in real underwater environments based on optimal simulation parameters. Through the sea trial experiment, we confirmed error performance was improved by applying the proposed weighting algorithm.

손은하(Son, Eun-Ha),신지은(Shin, Ji-Eun) 인문콘텐츠학회 2013 인문콘텐츠 Vol.0 No.28

본 연구는 영화 〈고양이를 부탁해〉에서 등장하는 인물 캐릭터와 미장센을 분석함으로써 이 속에서 직간접적으로 표현되는 인천의 로컬리티를 살펴보고 있다. 영화속 캐릭터들은 이 영화의 공간적 배경이 되고 있는 인천의 로컬리티를 특징적으로 드러내고 있다. 혜주와 지영은 일견 서로 상반되는 듯하지만, 궁극적으로는 인천에 대한 부정적인 인식을 표현한다는 점에서 서로 일치한다. 쌍둥이 자매 비류와 온조는 인천 화교가 지니는 역사성과 장소성의 아이러니를 보여준다. 태희는 성인, 남성, 중앙, 자본 중심주의의 기존 질서를 선망하며 그것을 자기의 욕망으로 취하는 대신, 대안적 질서를 꿈꾸며 타자들과 끝없이 접속하는 인물이다. 이 캐릭터는 허브와 네트워크 공간으로서의 인천을 상징적으로 보여준다. 마지막으로 영화 속 고양이가 보여주는 탈주의 의미에 주목하고, 또한 이 고양이가 ‘선물’로서 친구들 사이를 순환하며 일종의 우정의 공동체를 직조해 나가는 것을 밝힌다. 선물은, 현대 사회의 중앙(서울)중심, 화폐경제 등을 비판적으로 고찰하고 새로운 대안 공동체를 구성하는 데 중요한 의미가 있다고 본다. The purpose of this study is to find out locality of Incheon, which is released directly or indirectly from the movie, in viewpoint of character and mise-en-scene. The locality of Incheon, the background of this movie is distinctively exposed through the characters. Hye-ju and Ji-young have conflict characters at a glance, but eventually they are aligned with each other, in negative viewpoint of Incheon. Twin sisters, Bi-ryu And On-jo, show the irony of historicity and placeness of overseas chinese in Incheon. Tae-hee is a character who contacting the others endlessly while dreaming alternative orders instead of being envious traditional orders of adulthood, manhood, centrality and capitalism and taking them to her own desires. This character shows the emblem of Incheon as a space of hub and network. Lastly, we takes note of the meaning of escape of cat in this movie. This cat means a circulating “gift” for the characters reflecting formation of their friendship community. We consider that the gift has an important meaning as criticizing the contemporary centralism and monetary economy and constituting a new alternative community.

생삼을 쪄서 건조시킨 홍삼은 전통적으로 사용되고 있는 약재로서 면역, 내분비 및 중추신경계 작용을 증진시키며 염증을 억제하는 효과가 있는 것으로 알려져 있다. 본 연구에서는 그람 양성균의 세포벽 성분인 lipoteichoic acid (LTA)에 의한 염증반응에 홍삼추출액(RGE)이 항염증 효과를 가지는지 관찰하고 그 작용 기전을 연구하였다. BV-2 소교세포에서 RGE는 세포에 독성을 유도하지 않으면서 LTA로 인한 nitric oxide (NO)의 생성과 inducible nitric oxide synthase (iNOS) 발현을 억제하였으며, NF-kB p65의 핵으로의 이동과 IkB-a의 분해 또한 억제하였다. 한편, RGE는 농도의존적으로 heme oxygenase-1 (HO-1)의 발현을 유도하였으며, HO-1 siRNA를 처리했을 때는 RGE가 iNOS의 발현을 억제하지 못하였다. RGE는 HO-1의 발현에 관여하는 전사인자인 nuclear factor E2-related factor 2 (Nrf2)를 핵으로 이동을 촉진시켰다. 또한 RGE에 의한 HO-1의 발현은 phosphatidylinositol-3-kinase (PI-3K) 및 MAPK 억제제에 의해 감소되었으며, RGE가 Akt와 ERK, p38, JNK의 인산화를 유도하였다. 이상의 결과를 종합해보면, RGE는 PI-3K/Akt 및 ERK, p38, JNK 신호전달과정을 통해 HO-1의 발현을 유도함으로써 NO와 같은 염증매개물질의 생성을 억제한다는 것을 알 수 있다. 그러므로 홍삼추출액은 그람 양성균에 의한 신경염증과 염증관련 신경계 질환의 치료제로서 사용될 수 있을 것이라 사료된다. Korean red ginseng made from steaming and drying fresh ginseng has long been used as a traditional herbal medicine due to its effects on the immune, endocrine, and central nerve systems and its anti-inflammatory activity. In this study, we investigated the molecular mechanism responsible for the anti- inflammatory effects of a formulated Korean red ginseng extract (RGE) in response to lipoteichoic acid (LTA), a cell wall component of gram-positive bacteria. RGE inhibited LTA-induced nitric oxide (NO) secretion and inducible nitric oxide synthase (iNOS) expression in BV-2 microglial cells, without affecting cell viability. RGE also inhibited nuclear translocation of nuclear factor kappa B (NF-κB) p65 and degradation of IκB-α. In addition, RGE increased the expression of heme oxygenase-1 (HO-1) in a dose-dependent manner, and the inhibitory effect of RGE on iNOS expression was abrogated by small interfering RNA-mediated knockdown of HO-1. Moreover, RGE induced nuclear translocation of nuclear factor E2-related factor 2 (Nrf2), a transcription factor that regulates HO-1 expression. Furthermore, the phosphoinositide-3-kinase (PI-3K) inhibitor and mitogen-activated protein kinase (MAPK) inhibitors suppressed RGE-mediated expression of HO-1, and RGE enhanced the phosphorylation of Akt, extracellular signal-regulated kinases (ERKs), p38, and c-JUN N-terminal kinases (JNKs). These results suggested that RGE suppressed the production of NO, a proinflammatory mediator, by inducing HO-1 expression via PI-3K/Akt- and MAPK-dependent signaling in LTA-stimulated microglia. The findings indicate that RGE could be used for the treatment of neuroinflammation induced by grampositive bacteria and that it may have therapeutic potential for various neuroinflammation-associated disorders.

To improve Na+-saponite(SPT) film flexibility, we prepared SPT hybrid clay films with various poly(vinyl alcohol) (PVA) concentrations(0~10 wt%) using the solution intercalation method. In this study, we investigated the thermo-optical properties, morphology, and gas permeability of the SPT hybrid films. We also examined the relationship between the film properties and PVA content using wide angle X-ray diffraction measurements(XRD), field emission scanning electron microscopy(FESEM), differential scanning calorimetry(DSC), thermogravimetric analysis(TGA), thermomechanical analysis(TMA), ultraviolet-visible(UV-vis) spectroscopy, and oxygen transmission rate(O2TR) testing. The properties of the clay hybrid films were strongly affected by PVA filler content. The presence of a small amount of PVA was sufficient to improve the flexibility of SPT hybrid films.

일상생활의 공공성

신지은(Shin, Ji-Eun) 부산대학교 한국민족문화연구소 2018 로컬리티 인문학 Vol.0 No.20

공공성의 정의는 시대에 따라 달라졌고, 그에 따라 공공예술의 개념 역시 계속해서 변화해왔다. 본 연구에서는 기존의 공공성 논의에서 중요하게 다뤄지지 않았던 관객 대중과 일상성, 친교적 특성을 공공성의 핵심으로 주목하고자 한다. 현재 우리사회에서는 공/사의 경계가 분명하게 분리되어 작동되지 않는 경우가 많아졌다. 따라서 가장 사적인 영역에서 공적 이슈가 발생하기도 하고 가장 공적인 영역에서 권위적인 억압이 발생하기도 한다. 마찬가지로 가장 일상생활에 밀착한 예술이 중대한 공적인 의미를 가질 수도 있다. 이런 의미에서 공공성, 공론장, 공공예술의 논의는 일상생활의 맥락에서 재구성되는 것이 필요하다. 이를 위해 아렌트나 하버마스의 공론장, 공공영역에 관한 논의를 살펴보고, 이 논의를 짐멜의 친교 개념과 고프먼의 연극론으로 보완한다. 이를 통해 일상에서 분리되었던 예술이 점차 일상생활과 관객들에 다가갈 때 그 예술이 오히려 공적 성격을 띠게 된다는 사실을 확인하고, 이를 토대로 현대의 예술공론장의 성격과 방향에 대해 살펴볼 것이다. The definition of publicness has changed depending on the era, and therefore the concept of public art has also continually changed. The present study identifies the audience and daily everydayness, which have been excluded from discussions on publicness, as the core of publicness. In our society recently, the boundaries of public and private no longer clearly operate, and public issues occur in the most private domains, as does authoritarian oppression in the most public domains. Similarly, art that is closest to daily life can possess significant public meaning. Accordingly, there is a need to reconstruct discussions on publicness, the public sphere, and public domains in the context of daily life. To this end, this study examines discussions from Arendt or Habermas on publicness, the public sphere, and public domains, and supplements these discussions with Simmel`s concept of sociability and Goffman`s dramaturgy. This will verify that art which was separated from daily life comes to embody a public character when it gradually approaches daily life and audiences, and based on this we will be able to examine the character and direction of today`s public sphere of art.
