李琬夏,柳柄泰,智雄吉,朴大圭 成均館大學校 1980 論文集 Vol.27 No.-

Thiamine-HCI, Thiamine Propyl Disulfide (TPD) and Thiamine Tetrahydrofur furyl Disulfide (TTFD) were studied to stability in artifcial gastric juice and artificial pancreatic juice. And in the in vitro isolated intestine of rabbit, absorption rate of this compounds were examined. The results were as follows. 1. The stability of this compounds in artificial gastric juice and artificial panereatic juice were stable. 2. In the in vitro isolated intestine of rabbit, absorption rate of TPD was increased than that of thiamine-HCI about 20% after 120 minutes. And absorption rate of TTFD was much the same in the case of thiamine-HCI.

가족과 세대의 『무지개』(The Rainbow)

황규완 한국로렌스학회 2007 D.H. 로렌스 연구 Vol.15 No.3

The Rainbow can be evaluated as a kind of spectrum for family connection and changing generations These two changing processes from child to father and husband, and child to mother and wife can not be divided, but reflect and interact each other The relation between mother and child seems to be a one-way by forcing love-bullying' or 'ideal bullying' from mother, and repeated by generation to generation as the same pattern However, there are some differences between parents and their sons and daughters in the mode of interaction Lawrence argued that child exists in the interplay of two great life-waves, the womanly and the male This sort of relation variation between parents and child is derived from the differences between fatherhood and motherhood, and between generations as well as the personalities of Tom and Anna What he pursues is the harmony and balance of this relationship This is applied to the relations of male and female, husband and wife, father and mother, Parents and children, individual and society, individual and family and so on In each family, the individual's 'single being' should be established Child, birth and growing up are necessary parts for dealing with the theme of family The purpose and meaning to put children in a work come from their moral superiority to adults Children can be used as a device to break some conventions and values which have been Children have more and deeper implications than an ego and personality to express Lawrence's intention Children's vitality and newness are significant characteristics in his works to achieve the completeness of being and human relation The remembrance of Lydia's childhood is a motivation for recovery And the birth of Anna stands for revival to her mother The families in The Rainbow is a device which shows social changes Family reflects the social change and are related to various social conflicts and ideology Establishing 'single being' in family or between couple appears in his ideal goal The Rainbow show similar repetitions through generations The characters like Tom, Anna, Ursula represent each generation's pursues in various way Children's experiences and feelings are an important base in shaping an adult psyche Lawrence portrays parenthood and childhood with variety in terms of family members The Rainbow shows a metaphor of family, birth, child, growing-up, and generation as an ultimate theme of human life

D.H.Lawrence와 미국소설(Ⅰ):The Rainbow와 The Scarlet Letter : Centering on the relationship between The Rainbow and The Scarlet Letter

황규완 한국영어영문학회 경남지부 1995 현대영미어문학 Vol.12 No.-

The main characters. Pearl and Anna in The Scarlet Letter, and Hester and Lensky in The Rainbow have some similarities in their backgrounds of birth and growth environment. In character, they represent a similar symbol showing a new type of women or of dual women. In plot, their roles have similarities too. Conclusively the relationship between Lawrence's The Rainbow and Hawthorne's The Scarlet Letter is sure to have a close relation with Lawrence s criticism. Lawrence's The Studies of Classic American Literature shows that the criticism on Hester and Pearl in The Scarlet Letter is considered to refer to Lydia and Anna in The Rainbow. So Lawrence's criticism represents some connections between his works and Hawthorne's as well as plays a role of explaining his works. Like this. the characters described in their works and his criticism are considered to have in common a dual meaning and a dual role.

TMS320F240을 이용한 PWM 인버터 유도전동기 구동 시스템의 전도노이즈 저감을 위한 스위칭 기법

朴奎炫,金利勳,元忠淵,金奎植,崔世琓,咸年根 성균관대학교 2003 학술회의지원논문목록집 Vol.2003 No.-

PWM 인버터에 의해 구동되는 유도전동기에 발생되는 고주파 커먼 모드 전압은 전도성 EMI, 전동기 접지전류, 베어링 전류 및 다른 원치 않는 결과의 주원인이 된다. 인버터 제어의 무효벡터 스위칭 상태는 나머지 유효벡터 스위칭 상태에 비교하여 큰 커먼 모드 전압을 일으킨다. 그러므로 이 논문은 커먼 모드 전압을 완화하는 스위칭기법을 다룬다. 즉 정현파 PWM기법을 기본으로 한 커먼 모드 전압 제거방법을 제안하였다. PWM 신호는 각각의 정현파 기준신호와 120˚위상차가 나는 3개의 캐리어 파형과 비교하여 발생된다. 시뮬레이션과 실험적결과는 제안된 PWM 기법에서 커먼 모드 전압이 종래의 PWM 기법보다 약 66% 더 저감됨을 보였다. High frequency common mode voltage produced by PWM inverter fed induction motor is a major cause of conducted EMI. creation motor ground currents, bearing currents and other hamful products. The zero switching states of inverter control invoke large in comparison with the non-zero switching state of inverter control. We proposed a common mode voltage reduction method based on sinusoidal PWM technique. PWM signal are generated by comparing respective sinusoidal reference signal with three triangular carrier wave displaced of 120˚. Simulation and experimental result show that common mode voltages in the propsed PWM technique are reduced by approximate 66% more than conventional PWM technique.

A computer audit needs so that the modern information society that depends on computers preserves from computer unfairness is being committed by a human malice or intention. Acorrdingly, necessary conditions in order to execute the audit of EDP faithfully are as follows. 1) To secure auditors who have an expert knowledge about the audit of EDP. 2) Setting up the audit system and the audit standard that help measuring a computer control process. 3) The highest chief understanding of the audit of EDP. 4) To secure of resources that needs to fulfill a auditor's duties.

An experimental study waw carried out to investigate the nucleate boiling of pure water droplet placed on smooth stainless steel plate for various initial droplet diameters. From time dependent measurements of surface temperature just below the droplet and of the projected base area of droplet, the time averaged heat flux ?? and the sutface temperature ?? are obtained. The heat transfer characteristics are analyzed by correlating the heat flux ?? with ?? Applying analogy with single phase forced convection, the heat transfer data for nucleate boiling of water droplet are correlated with a bubble Reynolds number and a bubble Nusselt number which are based on the bubble departure diameter from the heated surface. The correlating equation is as follows; ?? (수식) where the various fluid properties are evaluated at the saturation temperautre.

Mucinous colorectal cancers have a poorer prognosis than which colorectal cancer produce low amount of mucin, but the exact mechanism is not well understood. The present study was undertaken to elucidate the exact mechanism of invasion and metastasis of high mucin producing colon cancer cells using mucin glycosylation inhibitor, benzyl-a-N-acetylgalactosamine. Materials and Methods: To evaluate the effect of glycosylated mucin on invasion and metastasis, in vitro invasion, metalloproteinases(MMPs) activity, cell-matrix protein binding, cell-cell aggregation, as well as endothelial leukocyte adhesion molecule(ELAM-1) binding and cell surface expression of various mucin related antigens were analyzed. Results: MMPs activity in conditioned medium and invasion of ECM-coated porous filters by benzyl-a-GalNAc treated HM7 cells were decreased. There was no difference between control and treated HM7 cells in terms of matrix protein binding assay, but treated HM7 cells showed higher homotypic cell adhesion. The binding activity of treated HM7 cells to ELAM-1 was significantly decreased and fixed cell binding of MoAb SNH-3, 19-9(specific for sialyl-Lewis X and sialy-Lewis A) were also significantly decreased. Conclusion: These results suggest that glycosylated mucin modulates ELAM-1 binding, MMPs activity and homotypic cell adhesion, therefore enhance invasive and metastatic properties of human colon cancer cells.
