재료를 달리한 김치의 발효중 미생물학적 및 화학적 변화
유영균 한국식품영양학회 1996 韓國食品營養學會誌 Vol.9 No.3
재료를 달리하여 6가지 김치를 제조한 다음 25℃에서 보관하면서 김치의 발효 중 미생물의 변화 및 화학적 변화를 관찰하였다. 김치는 호기성세균이 발효 첫날부터 이틀째까지 급격히 감소하다 그후 완만하게 감소하였다. 젖산균은 발효 첫날에 급격히 증가한 후 발효 후기까지 큰 변화를 나타내지 않았다. 김치 재료에 따른 미생물들의 증식의 차이는 크지 않았으나 멸치젓과 새우젓을 비롯하여 모든 재료가 첨가된 김치에서 발효 후기의 젖산균의 수가 가장 낮았다. 저장중 pH의 변화는 발효초기에는 멸치젓과 생강이 들어 있지 않은 김치가 가장 낮았으나 발효 후기에서는 김치별로 큰 차이는 나타나지 않았다. 발효 후기의 김치별 산의 생성정도는 젖산균의 증식정도와 밀접한 관계를 나타냈다. Population changes of aerobic bacteria and lactic acid bacteria and changes of pH, acidity, and total sugar content were investigated during the fermentation of Kimchies containing different ingredients at 25℃. The numbers of aerobic bacteria decreased from initial period of fermentation. Lactic acid bacteria increased during the first one day rapidly and thereafter they did not changes to the late period of fermentation in all Kimchies. pH decreased at first day of fermentation drastically and decreased slowly thereafter. Acidity increased on the third day of fermentation. Acidity was very low in Kimchi containing both salted anchovies and salted shrimp and this result was concerned with the number of lactic acid bacteria and changes of pH. Total sugar content decreased gradually from initial period to late period of fermentaion.
Sam Shepard의 Angel City에 투영된 영화산업의 자가당착
柳英均 서울市立大學校 1991 論文集 Vol.25 No.-
One of the most conspicuous features of the 20th century will be the appearance of films and film industry. Owing to the technical development in the concerned fields, feature films and mini-series produced for television, cable and pay television, and particularly those video-taped films allow easy access in millions homes to films recently released to the movie theaters. Nevertherless, it is often difficult to say with certainty whether the spectators of all those films of various modes witness the revelation of the truth or constitute the action as true. More often than not, it doesn't really matter to the spectators let alone to the producers. Many films of today are produced as no more than products of commercial business. And for that reason, they are more likely to offer us nothing but pipedreams or disposable fantasies, which prevent us from grasping the truth (if there's any) or from understanding our reality as they way it really is. Thus, more than any other previous periods, modern men of the late twentieth century often find fantasy and reality confused or even reversed. Sam Shepard is a scornful pop-culture addict. In other words, he has a double feeling for pop-culture--particularly for movies. And, in Angel City, we find such doubleness of his feelings--his heroes' Tom Wing field-like yearning for dream-machine identities and his own recognition of the self-destructive power in such yearnings. Rabbit is told his job is to save the film by creating "a meaningful" central character. What is wanted, Wheeler says, is "hard core disaster." Sheaprd is trying to say here that Hollywood has locked everyone into "the narrowest part of our dream machine" to prevent the evolution of any vital dreams or myths. The filmmaker's disaster film here inevitably reflects his own repressed nightmares of death and chaos, and they emerge into being during the apocalypse at the end of the play. A story pattern typical of those disaster films or monster films is that once a disaster or a manster is created, the creator may come the victim of his own creation. We must be aware that we the spectators are the very creators of those disaster films. They are created by filmmakers mainly because we wanted such films. Therefore, we must also be aware that we are the victims of our own creations.
랜포드 윌슨의 희곡작품에 나타난 미국의 이미지 : Talley's Folly와 5th of July를 중심으로 His 5th of July and Talley's Folley
柳英均 서울市立大學校 1992 論文集 Vol.26 No.-
Lanford Wilson's 5th of July and Talley's Folly are considered by many critics as his best crafted major works although they seem minor in their length and scope. Henry I. Schvey, a critic, highly praises Wilson's Talley's Folly by saying: "Paradoxically, by trying to do less, the playwright has actually accomplished far more; by paring the work down to its bare essentials and creating two such convincingly alive characters as Matt and Sally, Lanford Wilson indicates for the first time the promise of a major talent." It is apparent that Talley's Folly is thematically and stylistically related to most of his other plays. Most of Wilson's works are concerned with the relationship between the individual and the past. And there are many stage images that implicate the faded old glory of America or the shattered remnants of what's called The American Dream. In his later works, he uses the stage setting metaphorically to suggest a special relationship between the characters, their past, and their hope for the future. This stage scenery, for instance, the soon-to-be demolished hotel in The Hot L Baltimore or the dilapidated old boathouse in Talley's Folly, offers us a clear mental picture by which we could easily understand the psychological state of American intellects, their frustration and hope for the future of American especially after the two major wars-World War II and Vietnam War. We find an especially conspicuous thematic and stylistic affinity between his two most recent works, Talley's Folly and 5th of July. What distinquishes the most sharply these two plays from Wilson's other plays, however, are, according to Schvey, "his careful avoidance of cliched sentimentalized characterization. and his willingness to refine, to hone, his dramatic world down to its bare essentials."
실시간 코로나19 확진자 웹 모니터링 시스템에 대한 연구
유영균,조성욱,고동범,박정민 한국인터넷방송통신학회 2022 한국인터넷방송통신학회 논문지 Vol.22 No.1
본 논문은 캠퍼스 내 건물별 출입구에 출입명부를 관리할 수 있는 장치를 설치하고, 수집된 데이터를 근거로코로나19 확진자에 대한 감시 및 추적 시스템을 소개한다. 기존 QR 기반의 전자출입명부는 스마트폰으로 QR 코드를인식해야 하는 불편함과 건물 내 출입자의 온도를 측정할 수 없다는 단점이 있다. 또한, 국가가 캠퍼스 내의 확진자와접촉자 정보를 관리함에 있어, 구성원들에게 신속한 정보 공유와 추적이 쉽지 않다. 이는 확진자와 밀접 접촉한 이가또 다른 확진자를 만드는 경우를 초래할 수 있다. 따라서, 본 논문에서는 이에 대응하기 위해 얼굴 인식 기능과 온도센서를 포함한 장치를 캠퍼스 내 건물 출입구에 설치하고, 관리자가 실시간으로 건물별 구성원들의 출입현황을 모니터링하여 신속하게 추적할 수 있는 기능을 소개한다.
