대장균내에서 과량 발현된 재조합 프리-S2 펩티드를 면역친화력 크로마토그래피에 의해 분리 정제하였으며, 이 펩티드에 대한 중합 인혈청 알부민(pHSA)의 결합을 연구하였다. 프리-S2 부위의 pHSA수용체 활성을 검출하는 방법을 프리-S2-$\beta$ 갈락토시다제 융합단백질을 이용하여 개발하였으며, 민감도는 10-100 p mol의 프리-S2에 해당되었다. 또한 이 방법은 프리-S2 농도 결정 뿐 아니라 pHSA수용체 활성을 중화시킬 수 있는 인자들을 측정하는데 이용될 수 있다. Recombinant pre-S2 peptide was purified to apparent homogeneity from E. coli by immunoaffinity chromatography using monoclonal antibody and studied for its binding characteristics with monoclonal antibody and pHSA (polymerized human serum albumin). A simple and sensitive assay method for detecting the activity of pHSA receptor on pre-S2 peptide of hepatitis B virus surface antigen (HBsAg) has been developed using pre-S2-$\beta$-galactosidase fusion protein. The assay can be used for determining pre-S2 or factors neutralizing pHSA receptor activity. The sensitivity of the assay is about 10 to 100 pmol of pre-S2.

Pre-S2 region (amino acids 120-174) of hepatitis B virus surface antigen contains immunodominant and disulfide bond-independent epitopes. Using pre-S2 peptides (recombinant peptides 121-174/adw2, 134-170/adw2 and synthetic peptide 120-145/ayw), epitope and polyalbumin receptor region on pre-S2 were studied. Polyalbumin receptor assay and enzyme immunoassay provided evidences that the region of at least 12 residues (134-145) of pre-S2 was shared by epitope for an anti-pre-S2 monoclonal antibody and polyalbumin receptor. This region was shown to be hydrophilic and a possible β-sheet.

유전자 재조합 방법에 의해서 대장균으로 부터 재조합 인체 인터루킨-2 (rH IL-2, $Ser^{125}$-rH IL-2)를 과발현 시켰으며, 이 재조합 인체 인터루킨-2를 순수분리하여 그 생화학적 특성을 조사하였다. 분리 및 정제는 세포봉입체의 분리, 우레아 추출, 용해 및 젤여과 크로마토그라피 등을 사용하였으며, 정제된 인터루킨-2의 원형재현은 투석법을 사용하였다. 정제된 재조합 인터루킨-2의 순도는 전기영동 및 HPLC로 확인하였으며, 또한 결정을 얻음으로써 재확인하였다. 아미노말단 아미노산분석 및 아미노산배열순서를 일부 결정함으로서 정제된 재조합 인체 인터루킨-2가 천연 인터루킨-2와 동일한 일차구조를 갖고 있음을 확인하였다. Recombinant human interleukin-2 (rH IL-2, $Ser^{125}$-rH IL-2) was purified to apparent homogeneity from E. coli in high yield and characterized its biochemical properties for the establishment of preclinical screening system and therapeutic applications. The purification was carried out by methods involving isolation of inclusion body, urea extraction, solubilization and gel filtration chromatography. The renaturation of the product was achieved by extensive dialysis against the storage buffer. The purity was confirmed by SDS-PAGE and HPLC. Amino terminal amino acid analysis and partial amino acid sequence analysis showed that the primary structure of the recombinant protein (rH IL-2) was found to be identical with natural IL-2. The purity and the conformation of the rH IL-2 were al so confirmed by obtaining crystals of the recombinant protein.

Purpose: The purpose of this study was to examine the effect of tooth-brushing oral care on oral health and ventilator-associated pneumonia of patients in Intensive Care Unit (ICU). Methods: A total of 74 participants were recruited from a medical, surgical, or neurosurgical ICU at S Hospital in Seoul, Korea, from September of 2010 to January of 2011. An experimental group (n= 36) received oral care with tooth-brushing while a control group (n=38) received oral care with cotton ball and gauze. In both group, the oral care was done three times a day at least one minute for 7 days. Oral health was examined by the Modified Oral Assessment Guide before the intervention and each night. Results: There is no difference between the groups in aspect of passage of time (p = .603), interaction between time and intervention (p =.300), the performance intervention (p = .766), and the incidence of VAP (p = .486). Conclusion: The effect of oral care with tooth-brushing on oral health and VAP was not different from that of usual oral care in ICU. However, further study is necessary due to high attrition in this study.

소세키 문학 속 ‘살아가는 힘’ 고찰

윤혜영 ( Yun Hye-young ) 충남대학교 인문과학연구소 2022 인문학연구 Vol.61 No.1

본 연구는 동일본대지진 이후 ‘살아가는 힘’이라는 슬로건이 일본사회 전반에 대두된 것에 착안하여, 국민작가라고 불리는 소세키 문학 속의 ‘살아가는 힘’의 양상과 특징에 대해 살펴본 것이다. 연구대상은 아사히신문 연재소설 중 소중한 사람을 잃고 남겨지거나 버려진 사람들, 그리고 이들에게 상처를 준 사람들이다. 먼저 후지오의 어머니와 시즈는 유일하게 의지했던 딸과 남편을 갑자기 잃었다. 이후 후지오의 어머니는 수동적으로 자신의 잘못을 뉘우치지만 그 앞날이 밝지만은 않다. 시즈 또한 남편과 마찬가지로 자살을 하거나 아무것도 모른 채 일생을 외롭게 살아갈 것이 예상된다. 그리고 히라오카와 야스이는 친구와 부인에게 배신을 당하는데, 히라오카는 복수를 단행하고 야스이는 모든 것을 포기하고 만주로 떠나 방랑생활을 한다. 즉, 남겨지거나 버려진 자들이 역경을 극복하고 ‘살아가는 힘’을 찾아가는 과정은 그려지고 있지 않은 것을 알 수 있다. 후지오의 어머니와 히라오카를 포함하여 상처를 준 이들은 불행한 삶을 살아가는데 이것은 ‘도의’의 상실에 기인한 것으로, 분석결과 ‘도의’의 구체상은 자신의 목적을 달성하기 위해 다른 사람을 속이고 계략을 꾸미는 행동으로 귀결된다. 이것이 근대라는 격동기를 살아가는 인물들에게 전하고자 하는 소세키의 ‘살아가는 힘’에 대한 메시지라고 할 수 있다. Paying attention to the rise of the slogan of 'power to live' in Japanese society after the Great East Japan Earthquake, this study examines the aspects and characteristics of 'power to live' in Soseki literature, which is called a national writer. The subjects of this study are the people who have lost loved ones and are left behind or abandoned, and those who hurt to them in the Asahi Shimbun serial novels. First, Fujio's mother and Shizu suddenly lost their only dependent daughter and husband. Afterwards, Fujio's mother passively repents of her mistakes, but the future is not bright. Shizu, like her husband, is expected to either commit suicide or live a lonely life without knowing anything. And Hiraoka and Yasui are betrayed by their friends and wives. Hiraoka takes revenge and Yasui gives up everything and goes to Manchuria to live a wandering life. In other words, it can be seen that the process of overcoming adversity and finding 'power to live' of those left behind or abandoned is not depicted. Those who hurt them, including Fujio's mother and Hiraoka, live an unhappy life, which is due to the loss of 'morality'. As a result of the analysis, the concrete image of 'morality' results in the act of deceiving and plotting other people to achieve one's own purpose. This can be said to be the message of Soseki's 'power to live' that he wants to convey to people living in the turbulent period of modernity.

퍼즐 게임 플레이에 나타난 엔트로피 감소의 시뮬레이션

윤혜영(Yun, Hye-Young) 한국게임학회 2013 한국게임학회 논문지 Vol.13 No.5

본 논문은 엔트로피 개념을 적용해 퍼즐 게임 플레이를 분석함으로써 퍼즐 게임 플레이의 원동력을 고찰하였다. 엔트로피는 하나의 닫힌 시스템에서 시간이 흐름에 따라 증가하는 에너지의 불가용성과 무질서의 정도를 의미한다. 이때 닫힌 시스템의 엔트로피의 증가 정도는 이 시스템을 하나의 전체 즉, 場으로 볼 때만 파악가능하다. 퍼즐 게임 역시 플레이어가 하나의 기호를 조작하면 場 전체가 변화하는 닫힌 계 이다. <비주얼드>에서 플레이어는 자리바꿈이라는 기호 조작을 통해 플레이 場을 지속적으로 자리바꿈이 가능한 場으로 변화시킨다. 이것은 엔트로피의 관점에서 에너지의 가용성을 높이는 플레이 행위로 불 수 있다. 한편 <테트리스>에서 플레이어는 기호 조작을 통해 빈 공간 없이 기호들을 플레이 場 하단에 쌓는다. 이것은 엔트로피의 관점에서 질서를 추구하는 플레이 행위로 볼 수 있다. 이와 같은 퍼즐 게임의 플레이는 엔트로피 증가로 나아가는 물리적 세계에서 질서를 추구하는 인간의 삶의 과정을 시뮬레이션하는 행위로 볼 수 있으며 이는 플레이의 원동력이 된다. This Study analyzes dynamic of a puzzle game play by applying entropy law. Entropy is a concept that a quantitative measure of the amount of thermal energy not available to do work in a closed system. And amount of entropy can be measured only if we see the closed system as whole, the field. Puzzle game is also closed system. When player moves an object in game, it change a relationship among objects in play field. In <Bejeweled>, through an act of position change, player sustains a play field active. In respect of an entropy, this kind of play is considered as pursue of usability of the energy. In <Tetris>, player piles up objects without empty space. In respect of an entropy, this kind of play is considered as pursue of the order. Likewise, puzzle game play can be considered as simulation of a human's pursue of the order in an entropy increasing physical world. And this pursue is a driving force of puzzle game play.

도시 건축에서의 지역성과 역사성 -텐덴자, 이탈리아 건축운동(1965-1985)을 중심으로-

윤혜영 ( Yun Hye-young ),정문수 ( Jeong Moon-soo ) 부산외국어대학교 지중해지역원 2020 지중해지역연구 Vol.22 No.4

In today’s urban architecture, historicity and locality are impending issues both in preservation of modern buildings and construction of postmodern buildings. The duality implied by historicity and locality in urban architecture dates back to Tendenza, the Italian architectural movement that unfolded from the 1960s to the 1980s. This paper, a study on Tendenza, which suggested the importance of historicity and locality in urban architecture as a new architectural ‘trend’, is summarized as follows. First, the authors have searched out that Tendenza has succeeded in preservation of the history and the tradition asserted by Rationalism which occurred during the fascist period, the Neorealistic architecture and the Neoliberty movement after World War II, adapting these criteria to the contemporary time based on rationality. From this point of view, seeking to innovate modern architecture Tendenza can be evaluated as a Neorationalism movement. Second, the authors summarized that Tendenza emphasized thepreservation of the traces of history and the memory of the community in spaces and places. To realize them in architecture, it proposed a study on the tangible form and types of cities and buildings as a methodology. The so-called ‘Urban Typomorphology’ which is the methodology of Tendenza, emphasizes the history and traditions of communities, cities, and citizens rather than the nation-state, nation, and people. In addition, Tendenza provided the basis for the architectural movement that emphasized the duality, hybridity, and emotions that go beyond uniformity, unity, and reason which are the characteristics of modern architecture. In this aspect, Tendenza has a tendency to be regarded as a postmodern movement. Third, the authors have revealed that Tendenza has the characteristics of innovating modern architecture, while at the same time, it transcends the modern architecture towards ‘postmodern’ architecture. It is a bridge movement with the duality that connects the modern and postmodern architecture. The urban architecture of today has the impending issues, like locality and historicity similar to Tendenza’s.
