This essay exams the issues of aesthetic elements that come up when Korean novels get translated into Chinese language. The short story collection titled "An old well" written by Jeong Heui Oh in both languages are compared and analyzed by focusing on the mode of narrations. There are various narrative modes in "An old well". Each narrative mode properly functions for aesthetic effects and drawing meanings. In short, we can find a way to grasp its leitmotif the writer wants to indicate only when we carefully interpret the narrative modes in the original text. However, the narrative modes in Korean text have been simplified by changing its modes into direct narrative in Chinese-translated text. Thus the aesthetic effects in the original text have been spoiled and the Chinese text fails to deliver its meaning involved in the original narrative mode. Translation of novel invites consideration on both of its form and content on account of the text's uniqueness. Accordingly, a close examination and study of the original text should be completed beforehand.

이 글은 역사 기록을 상호 텍스트로 하여 『칼의 노래』에 나타나는 선택, 변형, 배제의 논리를 살피는 데 목적을 두고 있다. 이를 통해 하나의 소설 텍스트가 어떤 방식으로 '생산'되는지를 밝혔다. 또한 이렇게 소설이 생산되는 방식을 살핌으로써 『칼의 노래』가 소설적(근대적) 인물의 '세계에 대한 환멸의 서사'로 변화하는 양상을 추적하였다. 선택의 논리에서는 소설에서 어떤 시간과 공간이 선택되고, 어떤 인물이 선택됨으로써 소설의 내용·형식적 틀이 갖추어지는가를 보았다. 변형의 논리에서는 적대적 인물을 변형하고 전쟁의 의미를 변형함으로써 역사 기록과 달리 소설에서 '개인' 혹은 '주관성'의 의미가 부각되고 있음을 확인하였다. 배제의 논리에서는 특정한 시공간에 존재하는 역사적 인간의 특성이 배제되면서 소설에서 근대적(소설적) 인물의 특성이 부각되는 모습을 보았다. 이 글은 기존의 연구와는 달리 『칼의 노래』를 역사 기록과 상호텍스트적으로 비교 분석함으로써 한 편의 소설이 생산되는 방식을 고찰하였다는 의미를 지닌다. 이러한 분석을 통해 소설이라는 형식 속에 역사적 실재, 작가의 이데올로기와 상상력, 동시대의 욕망 등 여러 이질적인 요소들이 결합하는 양상을 확인할 수 있다. 또한 완결된 형식으로 봉합될 수 없는 텍스트의 요소들을 살핌으로써 안정되지 않은 체계로서 소설텍스트가 갖는 의미를 알 수 있다.

In the present work, novel orange peel was extracted with 100%EtOH (ethanol) and fractionated into four fractions namely F1, F2, F3, F4 which were eluted from paper chromatographs using 100%EtOH, 80%EtOH, 50%EtOH and pure water respectively. The crude extract and its four fractions were evaluated for their total polyphenol content (TPC), total flavonoid content (TFC) and radical scavenging activity using DPPH (1,1-diphenyl-2-picrylhydrazyl) assay. Their cytotoxic activity using WST assay and DNA damage by agarose gel electrophoresis were also evaluated in a human leukemia HL-60 cell line. The findings revealed that F4 had the highest TPC followed by crude extract, F2, F3 and F1. However, the crude extract had the highest TFC followed by F4, F3, F2, and F1. Depending on the values of $EC_{50}$ and trolox equivalent antioxidant capacity, F4 possessed the strongest antioxidant activity while F1 and F2 displayed weak antioxidant activity. Further, incubation HL-60 cells with extract/fractions for 24h caused an inhibition of cell viability in a concentration-dependent manner. F3 and F4 exhibited a high antiproliferative activity with a narrow range of $IC_{50}$ values ($45.9-48.9{\mu}g/ml$). Crude extract exhibited the weakest antiproliferative activity with an $IC_{50}$ value of $314.89{\mu}g/ml$. Analysis of DNA fragmentation displayed DNA degradation in the form of a smear-type pattern upon agarose gel after incubation of HL-60 cells with F3 and F4 for 6 h. Overall, F3 and F4 appear to be good sources of phytochemicals with antioxidant and potential anticancer activities.

Vitamin A palmitate, an oily drug which has low chemical stability and is poorly absorbed in the intestine, was formulated into a novel powdered dosage form. This is designated as a redispersible dry emulsion by freeze-drying technique. Before preparing a dry emulsion, vitamin A palmitate oil in solid in water (O/S/W) emulsion with soybean oil and coconut oil using Aerosil 200 as an emulsion stabilizer and polyoxyethylene-polyoxypropylene-blockcopolymer (Pluronic F68) as a surfactant was prepared. The resultants of the stability tests indicated that vitamin A palmitate O/S/W emulsion was improved on increasing the oil content of the formulation. The resultant dry emulsion particles have a good stabilities and free flow properties and readily released the oily droplets to form stable emulsions on rehydration. The drug releasing property from the resultant dry emulsion particles was dependent on factors such as amount of oily carrier(soybean oil) and surfactant(Pluronic F68) formulated. Above 80% of vitamin A palmitate content was released from the dry emulsion for 1 hour. It was deduced that vitamin A palmitate dry emulsion was definitely suitable for oral administration, since small droplets of vitamine A palmitate from the dry emulsion may alter the drug absorption profile resulting in bioavailability enhancement.

Instructional contents are used to demonstrate a technical process to teach and walkthrough certain procedures to carry out a task. This type of informational content is widely used for teaching and lectures in form of tutorial videos and training videos. Since there are questions and uncertainties for what could be the killer application for the novel wearables, we propose a self-instruction training application on a smart glass to utilize already-available instruction videos as well as public open data in creative ways. We design and implement a prototype application to help users train by wearing smart glasses specifically designed for two concrete and hand-constrained use cases where the user's hands need to be free to operate. To increase the efficiency and feasibility of the self-instruction training, we contribute to the development of a wearable killer application by integrating a voice-based user interface using speech recognizer, public open data APIs, and timestamp-based procedural content navigation structure into our proof-of-concept application.

Nowadays with the help of Location-Based Social Networks (LBSNs), users of Point-of-Interest (POI) recommendation service in LBSNs are able to publish their geo-tagged information and physical locations in the form of sign-ups and share their experiences with friends on POI, which can help users to explore new areas and discover new points-of-interest, and promote advertisers to push mobile ads to target users. POI recommendation service in LBSNs is attracting more and more attention from all over the world. Due to the sparsity of users' activity history data set and the aggregation characteristics of sign-in area, conventional recommendation algorithms usually suffer from low accuracy. To address this problem, this paper proposes a new recommendation algorithm based on a novel Preference-Content-Region Model (PCRM). In this new algorithm, three kinds of information, that is, user's preferences, content of the Point-of-Interest and region of the user's activity are considered, helping users obtain ideal recommendation service everywhere. We demonstrate that our algorithm is more effective than existing algorithms through extensive experiments based on an open Eventbrite data set.

The world is going through the most unprecedented time with the outbreak of novel Coronavirus disease (COVID-19), which has become a threat to millions. A Coronavirus is a group of viruses that cause a variety of diseases in mammals and birds leading to a range of illnesses in humans including common cold and more severe forms like severe acute respiratory syndrome Coronavirus (SARS-CoV), Middle East respiratory syndrome Coronavirus (MERS-CoV) and COVID-19, which are life-threatening. The virus gets its name from its shape which takes the form of a crown with protrusions around it. In December 2019, a pneumonia outbreak was reported in the Wuhan City of China, which was later traced to a novel strain of Coronavirus and termed as Novel COVID-19. It typically causes flu-like symptoms including fever, cough and shortness of breath and is transmitted through human-to-human and there is no cure for it till now. Thus, this bibliometric study has been carried out to analyze the research progress in Coronavirus and literature published during a period of 30 years (1989-2019). Data for the study were fetched from Web of Science(WoS) multidisciplinary database and the publication trends in terms of total articles, productive countries, institutions, journals, productive authors, most cited articles and authors, etc have been analyzed. In total, 4917 articles were retrieved; these were from 711 sources and were contributed by 14442 authors. The collaboration index was 3.11, which clearly indicates that there has been a lot of collaboration in this field. The most preferred journal for the study period was "Journal of Virology" and the maximum contribution has been from the University of Hong Kong.

A novel O-diethylaminoethyl chitosan (DEAE-chitosan) was synthesized via Schiff's reaction between chitosan and benzaldehyde. $C_2$ amino group was protected via Schiffs base reaction with benzaldehyde to form N-benzylidene chitosan. After reaction with diethylaminoethyl chloride, Schiffs base was removed by reacting O-diethylaminothyl-N-benzylidene chitosan and hydrochloric acid. Tensile strength of DEAE-chitosan was improved due to the incorporation of bulky side group in $C_6$ position of chitosan. DEAE-chitosan showed a pH-dependent swelling characteristics. Release rate of riboflavin was dependent on the water content of DEAE-chitosan that is a function of crosslinking degrees.

Video digests provide an effective way of confirming a video content rapidly due to their very compact form. By watching a digest, users can easily check whether a specific content is worth seeing in full. The impression created by the digest greatly influences the user's choice in selecting video contents. We propose a novel method of automatic digest creation that evokes a joyful impression through the created digest by exploiting smile/laughter facial expressions as emotional cues of joy from video. We assume that a digest presenting smiling/laughing faces appeals to the user since he/she is assured that the smile/laughter expression is caused by joyful events inside the video. For detecting smile/laughter faces we have developed a neural network based method for classifying facial expressions. Video segmentation is performed by automatic shot detection. For creating joyful digests, appropriate shots are automatically selected by shot ranking based on the smile/laughter detection result. We report the results of user trials conducted for assessing the visual impression with automatically created 'joyful' digests produced by our system. The results show that users tend to prefer emotional digests containing laughter faces. This result suggests that the attractiveness of automatically created video digests can be improved by extracting emotional cues of the contents through automatic facial expression analysis as proposed in this paper.

Electronic book(E-book)은 기존의 Paper-book이라는 매체를 통해 유통되던 텍스트 기반의 정보를 디지털화하여 온라인으로 유통시키는 디지털 콘텐츠 서비스이다. E-book이 본격적으로 관심을 끌게 된 것은 2000년 스티븐 킹(Steven King)이 총알 타기(Riding the bullet) 라는 소설을 E-book으로 출판한 것에서 비롯되는데, 이후 E-book에 대한 구매자의 관심이 매우 증폭되었고 미국을 비롯하여 유럽, 중국, 일본, 한국 등에서 E-book시장의 규모가 매우 커지고 있다. 본 연구의 목적은 세계 출판시장에서 E-book이 도입된 이후 Paper-book 출판시장과 E-book 출판시장이 어떻게 경쟁하며 확산해 나갈 것인가에 대한 실증 분석을 하는 것이다. 이를 위하여 두 시장 간의 관계를 경쟁관계를 고려한 확산모형인 Lotka-Volterra 모형을 사용하여 모형화하고, 국가별로 연도별 자료를 이용하여 확산곡선을 추정한다. 또한 곡선식의 계수를 추정함으로써, 두 시장 간의 경쟁관계 유형을 분석한다. 본 연구를 통해 Paper-book만 존재하던 출판 시장에 E-book이 도입됨으로써 책을 구매하는 구매자들의 수요 변화에 대한 분석을 시도한다.
