The problem of operating a freeze dryer to obtain a fixed final moisture content in minimum time is formulated as an optimal control problem. The energy radated from the heat plate, and total pressure in drying chamber are considered as control variables. Constraints are placed on the system state variables by the scorch point of the dried product and the melting point of the frozen interface. The optimum control policy at the beginning of the run, when neither of the two temperature constraints is active, has been establishen through a theoritical analysis under pseudo-steady state assumptions. For certain cases the nature of the overall optimum control policy has been found. The numerical solution of the steady and nonsteady state problem indicates that if a control policy is optimum for the steady state problem, then this control policy is also optimum for the nonsteady state problem.

<李娃傳>의 분석심리학적 연구

허근배 한국인문과학회 2006 人文學論叢 Vol.5 No.2

This thesis is on analyzing The Biography of LiWa<李娃傳> through Analytical Psychology and looking for deep meaning about it. C.G.Jung, the originator of Analytical Psychology, believed that the final aim of living is Self-actualization for combining one's consciousness and unconsciousness. This work shows how the main character LiWa(李娃) and ZhengSeng(鄭生), accomplishes Self-actualization. In this novel, the ego(自我) and the persona(面) in four persons' characters have appeared well. both XingYangGong(滎陽公) and JiMu'(枝姥) persona has suggested the conflict factor which a man-and-woman hero has to experience from the contents of the novel spread out. although LiWa is a partner about aristocrats with the status of a singing and dancing girl(枝妓) even if and saved much money, she gets married, she bears a child, and wants to raise. ZhengSeng(鄭生) got a lot of expectation of father. but he thinks that he will escape from the figure of the ego which is in sight externally. If feminine Animus realizes anything, it helps to a crucial inner companion so as to have courage, objectivity, manly tempers such as spiritual wisdom. perfect from feminine tempers a man is recognized about relation through integrations of Anima better, and to be inner is the same as what can create. The Biography of LiWa is a work expressed mental consciousness brazier humanitarianism of man and woman main character. if we look into center trouble of a novel, firstly an obstacle to stop up the accomplishment of affection is not the class or government authority, and be re-water LiWa or JiMu can know wicked thing. There is creative intention of The Biography of LiWa to a humanity recovery and faithfulness of LiWa when we see through this. Therefore, The Biography of LiWa is a story LiWa recovering humanity through consciousness anger, and there to be a focus by status rise through a trouble of monistic contradiction and polarity of the human existence.

Pad-dry-cure 방식으로 ethylene cyanohydrin을 이용하여 견직물을 acrylonitrile화 시킬때 건조 시간, curing 온도 및 시간, ethylene cyanohydrin처리 농도, ZnCl₂처리 농도 등 조건 변화에 따른 변화와 반응양식을 규명하고자 하였다. 가공된 견직물의 FT-IR과 DSC 분석을 통하여 다음과 같은 결과를 얻었다. Curing을 150 ℃에서 2분, ethylene cyano hydrin 처리농도 5%, ZnCl₂처리농도 0.1%, 건조 온도를 80 ℃로 하여 건조 시간 경과에 따른 견직물의 FT-IR 분석 결과, 건조 시간 경과에 따라 -0H(3,450cm^(-1)) 특성 peak가 전부 장파장 쪽으로 shift 되어 나타 났고, random coil에 의 한 amide peak(1,663cm^(-1))는 단파장 쪽으로 shift되어 β-sheet peak(1,635cm^(-1))와 중복되어 나타났다. 건조를 8℃에서 3분, curing을 110℃에서 2.5분, ZnCl₂농도를 0.1%로 하여 eylene cyanohydhn처리 농도에 따른 가공 견직물의 FT-IR 분석에서 -OH(3,450cm^(-1))특성 peak에서 변화가 나타나 견직물의 -OH기가 반응에 관여하고 있는 것을 알 수 있었다. 위와 같은 조건으로 가공된 견직물의 DSC 분석에서 eylene cyanohydnn처리에 의해 견직물의 열분해 온도는 무처리의 311'C에서 대략 320 "C로 상승하는 것으로 나타났다. 건조를 80'C에서 3분, curing을 110'C에서 2.5분, ethylene cyanohydrin 처리농도 5%로 하여 ZnCl₂처리 농도에 따른 가공 견직물의 FT-IR 분석에서는 촉매 처리농도 0.8%일 경 우를 제외하고는 -OH(3,450cm^(-1))특성 peak에서 대부분 무처리와 비슷한 결과를 보여주고 있으나, 0.8%의 경우에는peak에 큰 변화를 나타냈다. 같은 조건에서 가공된 견직물의 DSC 분석에서, ethylene cyanohydhn 처리에 의해 견직물의 열분해 온도는 촉매농도와는 관계없이 무처리(311'C)에 비해 가공 견직물(대략 320'C)의 열분해 온도가 상승점을 알 수 있었다. 건조를 80 "C에서 70초, eylene cyanohydrm처 리 농도 5%, ZnCl₂처리농도 0.8%, Curing시간을 2.5분으로 하고 curing 온도를 각각 110, 120, 130, 140, 150, 160 ℃로 변화시켜 가공한 견직물의 FT-IR의 분석 결과, curing 온도 110, 150, 160℃에서 -OH특성 peak의 변화가 크게 나타났다. 같은 조건으로 가공한 견직물의 DSC분석에서는 ethylene cyanohydrin 처리에 의한 견직물의 열분해 온도는 curing 온도에 상관없이 미처리구(311℃)에 비해 전부 열분해 온도(대략 320℃)가 상승함을 알 수 있었다. In this paper, when the silk fabric was modified by ethylene cyanohydrine, the reaction mechanism between both was studied at various treatment conditions such as curing temperatures and times, ethylene cyanohydrin concentrations and ZnCl₂concentrations. Through the FT-IR and DSC analyses of the treated silk fabrics, we found the results as follows : It was observed in FT-IR analysis of the treated silk fabrics that the -OH characteristic peak(3,450 cm^(-1))position and shape were all changed when drying and curing treatment conditions were at 80℃ for 3 minute and 110℃ for 2.5 minute, and the concentration of the ZnCl₂ was 0.1%. It indicated that the -OH group of the silk participated in the reaction between the silk fabric and ethylene cyanohydrin . From the DSC analysis, it was found that the pyrolysis temperatures of the treated silk fabrics by ethylene cyanohydrin which was processed in the same condition, were all increased from 311℃ to ab. 320 ℃. From the FT-IR analyses of the silk fabrics treated by ethylene cyanohydrin at the various concentrations of ZnCl₂, it was found that the -OH characteristic peaks(3,450 cm^(-1)) were similar to the nontreated one except that of the fabric treated at the ZnCl₂conconcentration of 0.8% when drying and curing treatment conditions were at 80℃ for 3minute and 110℃ for 2.5 minute, and the concentration of the ethylene cyanohydrin was 5%. In the case of the ZnCl₂ concentration of 0.8% soultion, a lot of change were observed in peak. From the DSC analysis of the treated silk fabrics which was processed in the same condition, it was showed that the pyrolysis temperatures of treated silk fabric were all increased from 311℃ to ab. 320℃, which was no relation with the concentration of ZnCl₂.

Diagnosis of Bovine Johne's Disease Using Multiplex Polymerase Chain Reactions In order to improve the early diagnosis of Johne's disease in ruminants, duplex polymerase chain reaction system for the detection of the etiologic agent of M. paratuberculosis and for the differentiation of other mycobacterial animal pathogens, such as M. bovis and M. avium, was applied. Genomic DNAs were purified from peripheral blood monocytes or milk macrophages and were used as templates in the duplex PCR. Detection of Mycobacterium spp. in the specimen was carried out by PCR using primer set specific to the mycobacterial 16S rDNA. And then, mycobacterial DNA-positive specimens were further differentiated with duplex PCR system which was composed of primer sets specific to 16S rDNA of M. avium complex and IS900 gene of M. paratuberculosis. The results were re-confirmed by Southern blot hybridization with oligonucleotide specific to the internal sequence of IS900 PCR amplicons. The applicability of this duplex PCR system was evaluated with DNAs extracted from clinical specimens of peripheral blood monocytes and milk macrophages. In summary, the duplex PCR amplification system described in this experiment is promising molecular technique for the early diagnosis of Johne's disease in ruminants.

The characteristics of rapid thermal annealed n-GaAs(100) is analyzed by the photoreflectance(PR) measurement. The Si highly doped n-GaAs was observed the FKO signals. The bandgap(E?) and surface electric field(E?) of as-grown sample were 1.423 eV and 2.65×10? V/cm, respectively. In the rapid thermal annealed samples, E? was increased and then decreased by increasing anealing temperature, and it was increased again at 800 ℃. These results could be explained by decreasing of the non-radiative recombination on samples. For the time dependence of the rapid thermal annealing, the amplitude of the PR signal was maximum at 20 sec, and E? was increased by 10.7 times than that of as-grown sample.
