본 연구는 국내산 천일염(장판염, 토판염)의 성분 비교와 이를 이용하여 무 절임을 제조할때 첨가한 스타터와 함께 발효기간 동안의 변화를 알아보고자 수행하였다. 그 결과 두 소금간의 일반성분 중 수분함량은 차이를 보였지만 회분함량은 그룹간의 차이를 보이지 않아, 생산시기가 동일한 점을 고려할 때천일염 생산방식에 따른 차이라고 판단된다. 이들의 무기성분 함량은 소금의 주성분인Na 함량은 큰 차이를 보이지 않았고, Ca, K 그리고 Mg 함량은 장판염이 높게 측정된 반면, Fe 그리고 Zn 함량은 토판염이 높게 측정되었지만, Ca 함량을 제외하고 크게 차이를 보이지 않았다. 천일염의 당도 측정 결과 10.70 Brix로 높은 함량을 나타내어 어떤 종류의 당으로 구성되었는지에 대한 정성분석 연구가 요구된다. 무 절임 중 천일염과 스타터 첨가에 의한 발효 변화를 관찰하였을 때 스타터를 첨가한 그룹이 스타터를 첨가하지 않은 그룹보다 활발하게 유리당, 유기산 등 2차 대사산물을 생성하여, 우점종으로서 초기 미생물조절에 영향을 끼쳤다고 판단된다. 그리하여 실험에 사용된 Leuconostoc mesenteroides B-512F 균주의 스타터 첨가가 발효과정 중 미생물 균총 변화에 큰 영향을 주므로, 발효식품 제조 시 초기미생물 조절자로서의 명확한 역할 구명이 필요할 것으로 생각된다. In this study, the effects of the use of a starter on radish soaked at 4℃ for 28 days using two kinds of domestic sun-dried salt (white and gray salt) were determined. As a result, the moisture contents of the radish soaked with white and gray salt were 7.93 and 4.50%, respectively. The salinity levels were found to be equal (90%). No significant difference was found between the two groups in terms of the mineral contents of the salts therein (37812.41±1922.95 and 39755.13±1205.70 mg/100 g, respectively). However, iron and zinc contents of gray salt were higher than those of white salt while the calcium, potassium, and magnesium contents were lower than those of white salt. After the addition of the starter, the sugar content increased, the pH decreased, and the total acidity rapidly decreased compared with the non-starter group during fermentation. The total microorganism count of the two groups increased during the fermentation period of 28 days. From the initial fermentation for 7 days, the lactic acid bacteria in the non-starter group increased while those in the leuconostoc starter group steadily increased within the whole fermentation period. The Leuconostoc spp. in non-starter group increased, but that in the starter group decreased to pH 4.0 on day 14.

이동통신 트래픽 예측을 위한 클러스터링 기법

나세현(Se-Hyeon Na),김영준(Young-Jun Kim),유현민(Hyeon-Min You),안희준(Hee-Jun Ahn),홍인기(Een-Kee Hong) 한국통신학회 2021 한국통신학회 학술대회논문집 Vol.2021 No.6

급증하는 모바일 트래픽을 네트워크가 적절히 수용하고, 네트워크 성능을 유지 관리하기 위해서는 미래에 발생할 트래픽을 예측하는 것이 중요하다. 본 논문에서는 시공간 데이터를 학습시키는데 적합한 딥러닝 알고리즘인 ConvLSTM(convolutional LSTM)을 사용하여 미래 트래픽 데이터를 예측한다. 트래픽 데이터는 시간과 공간에 따라 발생하는 양상이 제각각이기 때문에 서로 다른 양상을 보이는 트래픽 데이터를 한꺼번에 학습 데이터로 사용하여 학습시키는 것은 모델의 성능을 저해할 수 있다. 따라서 본 논문에서는 나름의 트래픽 유사성에 대한 기준을 정하여 유사성에 의한 클러스터링 알고리즘을 통해 클러스터 단위로 트래픽 데이터를 학습시킨다. 본 논문은 연구에 사용한 유사도 기반 클러스터링 방법에 대해 설명하고, 클러스터의 개수를 증가시켜 학습시킬 때의 트래픽 예측 성능의 변화를 분석한다. 연구 결과, 클러스터링 개수를 증가시킬수록 예측 오류가 줄어드는 것을 확인할 수 있었다. 그러나, 너무 많은 클러스터로 나눌경우 오히려 예측 오류가 증가하였다.

식이에 첨가한 Conjugated Linoleic Acid (CLA)가 만성적으로 알코올을 섭취한 쥐에서 간조직의 항산화 체계에 미치는 영향

김세나(Kim Se-Na),김민석(Kim Min-Seok),박현서(Park Hyun-Suh) 韓國營養學會 2007 Journal of Nutrition and Health Vol.40 No.2

The study was designed to observe antioxidant activities of conjugated linoleic acid (CLA) by determining antioxidant enzyme protein levels [cytochrome P4502 E1 (CYP2E1), Copper, Zinc-superoxide dismutase (CuZn-SOD), glutathione peroxidase (GSH-Px), glutathione S-transferase (GST)] by Western blot analysis and the levels of α-tocopherol and 2-thiobarbituric acid reactive substances (TBARS) in the liver of chronically ethanol-treated rats. Sixty Sprague Dawley male rats were divided into 3 groups (Control, EtOH, EtOH+CLA). All rats were fed Lieber-DeCarli liquid diet for 4 weeks by pair-feeding against the EtOH group. The liquid diet was supplemented with l.77g CLA mixture per kg diet in the EtOH+CLA group. Isocaloric maltose dextrin was added in replace of 50g ethanol (36%㎉) for the Control group. Ethanol ingestion significantly increased the levels of CYP2E1 protein and TBARS, but significantly reduced CuZn-SOD protein level and increased GST protein level. There was no significant effect on the level of GSH-Px protein and α-tocopherol in the liver by ethanol. CLA supplementation with ethanol significantly increased the levels of CuZn-SOD, GSH-Px and GST and also significantly attenuated TBARS level, whereas there was no significant effect on the levels of CYP2E1 protein and α-tocopherol by CLA. Overall, the CLA supplemented to ethanol could significantly increase the levels of CuZn-SOD, GSH-Px and GST proteins and reduce the level of TBARS in the liver of chronically ethanol-treated rats.

박완서 소설의 진리발화적 서사방식 고찰

김세나 ( Kim Se-na ) 한성대학교 한성어문학회 2019 漢城語文學 Vol.41 No.-

Park Wan-Seo is one of the authors who repeatedly narrated trauma of Korean War. Based on her motif of ‘brother’s dat’, she verified the process of remembering her family’s trauma through history. Thus, there is a need to confirm the intention of author to create repeatedly. This paper focused on the process of author’s narrative intention that activates narration through repetition implemented based on principle like torture cell that casts literature. Repetition and variation of motif through novel is as effective as truth narrating by itself, and it is related to will to create of an author. Park’s novel has truth-speech narrative characteristics. Repetition of motif in novel indicates the status of author’s loyalty. Each of her novels affect one another and forms ‘pure difference’ and builds up significance by obtaining the status of new subject through repeating the past history. Author’s narrative intention that utilized repetition and variation does not only contain significance of writing to reenact the past and avenge. Her novel writing is a work of repeating the loss through novel by expanding the significance of recovering the lost subject. Through creation process of signifying and dissecting the trauma, the author forms ethical status. As novel is a media based on creating language, it is a tool that indicates creative imagination of author. Park’s narration that variate the trauma repeatedly is an implementation of truth speaking by itself by speaking about the truth.

오정희 소설의 기억 서사 형식 연구

김세나(Kim, Se-na) 국어국문학회 2014 국어국문학 Vol.- No.169

오정희의 「바람의 넋」은 기억-서사의 형식이 주체 구성을 위한 하나의 방법론이 될 수 있음을 살필 수 있는 작품이다. 기억은 인간의 삶에 실존 조건이 되며, 주체는 과거의 기억을 망각하거나 회상하는 과정을 통해 새로이 자신을 구성할 수 있다. 기억과 망각, 회상은 하나의 짝을 이루면서 주체의 자리에 이르기 위한 형식이 된다. 「바람의 넋」의 은수에게 과거의 망각된 원체험은 그 파상적 힘을 발휘하며 현재의 삶에 정체를 알 수 없는 불안을 야기한다. 회상은 현재의 위치에서 과거의 기억을 불러일으킨다는 점에서 언제나 파상적 힘을 발휘할 수밖에 없다. 뿐만 아니라 현재의 삶이 과거와 단락될 수 없다는 점에서도 회상은 주체성 개념과 긴밀한 관계를 지니게 된다. 과거의 해소되지 못한 기억들을 피하거나 덮어두려 하면 주체의 자리에 서지 못하게 되는 것이다. 은수의 잦은 가출과 이를 용인할 수 없는 주변 상황의 대비를 통해 「바람의 넋」은 망각과 기억하기의 행위를 극대화하는 효과를 발휘하고 있다. 오로지 홀로 겪어야 하며 텅 빈 상태, 자신이 무(無)화되는 체험을 겪는 과정을 통해 은수는 주체의 자리에 설 수 있게 된다. 이는 자신의 분열을 감당하면서 부정성을 체현하고자 하는 모습으로 형상화되며 주체로 자리매김되는 과정으로 나타난다. 우리 문학에서의 오정희가 보여준 세계의 특징은 개인의 내밀한 경험영역을 누구보다도 정밀하게 드러내 보임으로써 존재의 불안정성에 의문을 제기하는 것이다. 특히 평범한 일상생활 속에서 무료한 존재적 삶을 살아가는 중산층 혹은 여성의 내적세계를 집중 조명하면서, 자칫 무미건조한 일상성의 소재로 전락할 수 있는 대상을 해부하여 진단하는 듯한 세밀성을 보인다. 「바람의 넋」에 나타난 기억-서사의 틀은 개인의 일상성 안에 흉물스럽게 자리하고 있는 불안과 초조의 표면을 들춰내고, 개인의 문제와 역사?사회적 문제로 확장하는 시선을 보여주고 있다는 점에서 의의가 있는 작품이다. 뿐만 아니라 삶을 이분법적 질서로 구획하여 바라보는 태도를 지양하는 작가의 의도 역시 고찰할 수 있었다는 점에서 그 의의가 있다. The Spirit of Wind by Oh Jeong Hee is a work that offers a glimpse on how the style of memory-narrative can become a method to form an agent in itself. Memory becomes an existential condition to human life and the agent, through the process of forgetting one’s memory or reflecting on it, can form a new self. Memory and oblivion, as well as remembrance form partners to one another and become a style to reach the right location of the self. The Spirit of the Wind shows Eunsu’s forgotten memory which exerts a destructive power and causes anxiety that cannot be pinpointed. Remembrance can only exert destructive power in that it triggers the memory of the past from the vantage point of the present. Moreover, because of the fact that the life in present tense cannot be severed from that in the past tense, remembrance is closely related to the concept of agency. When one tries to avoid or gloss over unresolved issues and memories from the past, the self loses its proper location. The frequent running away of Eunsu and the surrounding environment that does not tolerate such behavior shows a contrast where the act of forgetting and remembering exert the greatest power in The Spirit of the Wind. Through experiencing a state where a void is felt by oneself and where oneself turns into nothing, Eunsu can finally establish his self agency. This is expressed through his effort to survive and experience his self-division and negativity, through which he is reborn as a self-willed being and agent of his life. The world shown in Oh’s novels is characterized by a detailed focus on internal experiences of individuals, thereby posing a question on the instability of existence. In particular, by shedding light on the internal lives of the middle class or women who are going through their daily motions, the author anatomizes the subject that could have been relegated to a topic of dull, daily life. The framework of memory-narrative shown in The Spirit of the Wind is significant in that it unveils the instability and anxiety hidden inside our daily lives and applies a viewpoint where the individuals’ issues are expanded in a historical-social context. Moreover, the intention of the author to avert a binary perspective in viewing the world in either black or white can also be perceived.

We surveyed 821 children (ages 12-15 y) in Daejeon city and Cunngcheong province, Korea for their use of vitamin·mineral supplements (VMS), either over-the-counter drugs and/or health functional foods (HFF). We also considered the significant variables of VMS use, including demographic characteristics, health-related variables, eating habits and nutritional beliefs of VMS by subjects. The frequency of VMS use was 24.8% and, in comparison to counterparts, it was higher in subjects attending middle school (p<0.001), in those living in a large city (p<0.001), in those with a high monthly family income (p<0.05), and in those with high concerns about school performance by parents (p<0.01). Self-health concerns by subjects (p<0.05) and concerns about health of offspring by parents (p<0.01) were higher in users than in nonusers. Eating habits of subjects did not affect the use of VMS. Users had a more positive view concerning the potential health benefits of VMS than did nonusers (p<0.05). Most users took VMS when they were healthy (78.9%) and expected `disease prevention and health maintenance` (44.6%). However, most users did not feel any special effects from VMS use (58.8%), and they got their information on VMS through family and relatives (53.9%). Users of VMS preferred vitamin C supplements (44.2%) and Ca-supplements (56.9%). Therefore, the results show that VMS use is widely spread among the subjects, and that use of VMS is influenced by multiple variables and subjective criteria. Therefore, practical guidelines on VMS use for children`s health and growth should be given through nutritional education.

The traditional culture has been developed for a long time with an unique property according to folk character, custom and environment within an area. Especially in 1906, when the westerners were interested in oriental cultures more and more, Paul Poiret presented Japanese traditional dress of napping sleeve coats and harem pants, henceforth japanese fashion theme began to rise. The Japanese style rose as an important fashion item of the modern fashion, with various fashion themes such as orientalism, ethnic, folklore, ecology, etc., needless to say of activities of Japanese designers. The revealed patterns on Japanese dress and it`s ornament plays a role of expressive decoration as well as stand for the nation, the ideology of the age and aesthetic consciousness. For this reason, it is necessary to study Japanese traditional patterns expressed in modern fashion systematically. Therefore, in this research, the demonstrated Japanese traditional patterns on the modern fashion were divided into natural, artificial and complex design and were looked out the characteristic, furthermore it was studied in regard that Japanese patterns were how to apply in modern fashion. It was concluded that the characteristics of the Japanese traditional patterns presented in the modern fashion were as follows: first, creation of environmental friendly design using plenty of natural materials; second, expression of paint-like impression and beauty of margins by simplifying of patterns; third, expression of amusing design by using bright colors and print; finally, various patterns were spreaded out complicated on dress. The characteristics of Japanese traditional patterns in the above were expressed in the modern fashion.
