홍완수,윤지영 한국조리과학회 2003 한국식품조리과학회지 Vol.19 No.4

The purpose of this study was to develop methods for foodservice employees to perform by measuring their levels of sanitation and hygiene practices. The employees' sanitation and hygiene competency list for school foodservice was developed on the basis of the job standardization. The competency list was divided into three parts; (1) before starting the work, (2) during the work and (3) after the work. The levels of the employees' sanitation and hygiene practices were evaluated by dietitians and by the employees themselves. Most schools had conventional foodservice systems (83.4%), which were operated by contract management (94.8%). It was found that the highest practice level related to sanitation and hygiene before starting work, with the lowest levels observed after work. The item related to the cleaning and sanitizing of dishes had the lowest practice level score. Employees perceived their sanitation and hygiene practice after work to be worse than before starting and during work. The items of "Clean and sanitize all large stationary equipment after every use, and record equipment monitoring chart" and "Do not clean dishes and utensils in production area" had the lowest scores by employees. The scores of the employees were similar to the perception of the dietitians.

Three different doengjang(fermented soybean paste) were prepared by using B. subtilis SS103 with high angiotensin converting enzyme(ACE) inhibitory activity, Asp. oryzae and mixed culture of two organisms, respectively. Quality characteristics and the inhibitory activity were compared. β-Amylase activity rapidly increased during 30 days of fermentation, but lower activity was found in doenjang prepared with B. subtilis. However, α-Galactosidase activity decreased for 15 days of fermentation and little activity was observed after that fermentation period. Protease production tended to increase during the fermentation. High protease activity was found only in doengjang prepared with Asp. oryzae, but the doengjang prepared with B. subtilis SS103 showed very low activity. Total isoflavone content at 90 day fermentation was the highest in doengjang prepared with mixture of Asp. oryzae and B. subtilis. ACE inhibitory activity increased during the fermentation period. The highest activity was found in doengjang made with mixture of Asp. oryzae and B. subtilis. Sensory evaluation on doengjang itself and its soup indicated that doengjang made with mixture of Asp. oryzae and B. subtilis showed higher acceptability on taste, flavor and color than those prepared with only Asp. oryzae or B. subtilis, respectively.

택사추출액이 benzo(a)pyrene에 의해 유도된 간장해에 미치는 영향

尹水弘,徐旼志,河勳 대구효성가톨릭대학교 1996 연구논문집 Vol.52 No.2

The protective and therapeutic effects of Alismae Rhizome extracts depending on solvent polarity on rat liver injury induced by benzo(a)pyrene were investigated. As parameters in serum and liver, alkaline phosphatase, glutamate oxaloacetate transaminase and glutamate pyruvate transaminase activities were observed. The results were as follows: B(a)P intoxication significantly increased alkaline phosphatase, transaminase activities of serum and liver compared with normal group. Especially CHCI₃fraction revealed the most powerful liver protective and/or therapeutic effect of 4 extracts in serum transaminase activities and in hepatic alkaline phosphatase and glutamate oxaloacetate transaminase, maybe due to presence of alkaloid, triterpenoid and flavonoid in this fraction. Above-mentioned results strongly suggested that Alismae Rhizoma be a promising liver-protective drug. So more study will be needed to find principle hepatotropic Alismatis Rhizoma.

The Stone Angel : 자유를 향한 자기 인식

여도수,홍지영 공주영상정보대학 2000 논문집 Vol.7 No.-

Margaret Laurence는 진정으로 훌륭한 캐나다의 작가들과 그들의 작품들이 더욱더 많이 세계적으로 알려지고 그 진가를 인정받기를 원하며, 소설작품의 영역이 국가적인 경계를 넘어 더욱 확장되어야하고 동시에 독특하고 특수한 것이 보편적인 것이 되어야한다고 강조한다. 즉, 캐나다 사람들과 캐나다의 문화와 역사 등 캐나다적인 것에 대하여 객관적이고 정확한 관찰을 통한 진지한 글쓰기를 할 때 비로소 캐나다적인 목소리를 제대로 인식하고 이것이 보편성을 얻는다는 것이다(Lever 28). 이러한 그녀의 관점에서 볼 때 Manawaka 소설들은 캐나다적인 인물과 그 환경에서의 경험이라는 독특성과 인간애를 향한 인간의 내적인 삶과 인간들의 외부관계에 대한 주제라는 점에서 보편성을 지닌다. 따라서 그녀의 Manawaka 소설들에서는 주요 인물의 내적인 삶과 자아인식을 향한 진보, 이에 따른 삶과의 화해를 그리고 있으며, 그 대표적인 작품이 The Stone Angel이다. 척박하고 험난한 캐나다 환경에 적응하는데 필수적인 자존심과 강인한 성격은 주인공 Hagar의 생존을 가능케 했지만 그 성격의 부정적인 영향으로 인하여 인간미를 잃어버리고 자신은 물론 다른 사람들과의 관계에서 황폐하고 곤란한 삶을 산다. 이러한 그녀에 대하여 Laurence는 "I love her, at the same time, 1 deplore the kid of person she is. Many of her characteristics are extremely unlovable. I mean, she does a lot of damage to the very people she loves - a lot of psychic damage"라고 지적하고 있다(Fabre 206). 그러나 Hagar는 작품이 후반부로 진행될수록 위엄과 자존심으로 인해 죽어있었던 감정과 구속의 억압에서 벗어나 재탄생과 변형을 향해 나아간다. 자신과 주변사람들에게 불행을 초래했던 자신의 결함을 인식하고 인간애와 인간이해를 언행으로 표현하므로써 비인간적인 자존심의 속박에서 벗어나 자유를 추구한다. 그녀는 이러한 자아인식을 위하여 현재에서 과거기억 속으로의 여행을 떠나며 작품 전반에 걸쳐 나타나는 과거와 현재의 유기적인 시간구조는 Hagar의 의식의 변화에 커다란 영향을 주고 작품 전체에 통일감을 부여한다. 이처럼 캐나다적인 독특한 인물을 주인공으로 보편적인 인간의 제문제를 다룬 이 작품의 효과에 대하여 Laurence는 다음과 같이 말하고 있다 "I wrote about Hagar as one individual old woman, who certainly came out of my own background. But I was astonished when a number of other Canadians wrote to me or said to me that this was her grandmother. And I didn't know that it was going to turn out to be everybody's grandmother"(Kroetsch 48-49). 이상에서 살펴본 바와 같이 The Stone Angel에서 Laurence는 현재와 과거의 상호보완적인 시간구조 속에서 캐나다적인 환경에서 생존을 위해 필요한 강인함과 자존심의 부정적인 면을 부각시켜 객관적인 관점에서 이를 비판하고 인간미와 인간다움의 중요성을 강조하고 있다.

재료에 따른 알루미나 내화물 Matrix의 소결특성과 고온 Bending에 미치는 영향

배지수,이길홍 조선대학교 생산기술연구소 2006 生産技術硏究 Vol.28 No.2

The results of test by adjusting various raw materials and composition conditions for the evaluation of the bending characteristics of AluminaUmullite refractories are as the follows. 1) We have confirmed that the sintering was carried out relatively well even at the temperature of 1550℃ and composition reaction of mullite was well accomplished when we used Kaolin and Clay as the raw materials of matrix but the sintehng temperature must have been over 1650℃ when we used fine powder of silica and silica fume. 2) Matrix specimen that has used silica as raw matehal was poor in sintering at the temperature less than 1650℃ and composition reaction of mullite was also indicated as low and mullite composition was not generated at the temperature of 1450 ℃. Silica fume with relatively more fine powder showed similar feature but the level of sintehng and mullite was higher. 3) We could confirm, through the results of measuring the bending characteristics of alumina-mullite refractohes at high temperature by differentiating raw materials and supplies of the usage of matrix, that fine powder of silica used as raw materials and supplies showed good characteristics of bending at high temperature and we believe this is because high temperature liquefied materials generated by the impact of impurities contained in raw materials and supplies are greatly affecting the high temperature bending.

AWRR 셀 스케쥴링 알고리즘

신승수,신동화,지홍일,최승권,조용환 충북대학교 산업과학기술연구소 2002 산업과학기술연구 논문집 Vol.16 No.1

The Binary Scheduling Wheel(BSW) algorithm was proposed to carry on manage buffer efficiently at implementing of WRR scheduler. But, BSW algorithm cause serous performance degradation of cell delay and maximum queue length because it allocates more weight than the weight allocated actually in VC and could not serve cell if the VC queue is empty. In this paper, we propose new BSW of the old BSW structure. Also, we develop a cell scheduling algorithm which is suitable for the new BSW structure. The proposed BSW structure and the developed algorithm are capable of maintaining the allocated weight of each VC correctly, and decrease average cell delay and average buffer length by serving other VC cell when the selected VC queue is empty, and increase cell service ratio as a whole. The evaluation results show that the proposed structure can implement WRR algorithm more efficiently than the old BSW.
