To investigate the elasticity loss of toothbrush according to the strength of pressure. the shape of brushing plane and the duration of use, thirty toothbrushes of five models were used for this examination among the toothbrushes for adults which have been marketed in the Republic of Korea. After 200g/㎠. 300g/㎠, or 400g/㎠ for 1, 2 or 3 month were loaded on toothbrushes, in rolling method the effect of the duration and strength of pressure and the change of the shape of brushing plane on the elasticity loss of toothbrushes was determined using Toothbrush Stroke Testen(CHUMDAN SYSTEM, Korea). The results are as follows; 1. The elasticity loss of toothbrushes according to 200, 300, or 400g/㎠ pressure was 11.11%, 25.21%, 30.84%, respectively. The elasticity loss of toothbrushes was increased with increasing the strength of the pressure (p<0.001) 2. The elasticity loss of the toothbrushes according to 1, 2, or 3months of the duration of use was in 15.60%, 22.09%, 29.47%, respectively. The elasticity loss of the toothbrushes was increased with increasing the duration of the pressure(p<0.001). 3. The elasticity loss of toothbrushes of convex plane according to 1, 2 or 3 month of the durate of use was 10.36% 18.29% and 24.20% respectively, that of toothbrushes of flat brushing plane according to 1, 2 or 3 months of the duration was 20.08%. 25.87% and 34.74%. respectively. The elasticity loss of the toothbrushes or flat brushing plane was higer than that of convex brushing plane(p<0.05). These results show that the property of the KS is optimal according to the pressure of toothbrushing, the shape of toothbrushos and the duration of toothbrushes using must be checked, and the further studies are needed about that.

Biometric encryption refers to a process of secure key management. Biometric encryption does not directly provide a mechanism for the encryption/decryption of data, but rather provides a replacement to typical passcode key-protection protocols. Although the process of biometric encryption can be applied to any biometric image, the initial implementation was achieved using fingerprint images.

In this paper, the quick response control of induction motor was researched by presenting indirect vector control algorithm to improve the dynamic performance of induction motor, resulting in quick response characteristics such as DC motor. Speed detecting method was used by M/T method and made the simple speed calculation by the presentation of the a1gorithm using the the HSI.0 pin and HSI TIME of 80196KC. It was used each ,PI controller for current controller and speed controller of-control algorithm, 80196KC to CPU for fast velocity processing computation in designing control system, and the way of PWM for removing the current harmonics of voltage source inverter We would like to confirm through experiment the relatively fast response velocity and the superior quick response control characteristics with variable command-speed, applying proposed system to 1[HP] 3ø induction motor.

In this paper, an effective phoneme recognition method for large vocabulary speech recognition system has been studied. VQ(Vector Quantization) is used as a front-end system for HMM(Hidden Markov Model) recognizer. Optimum number of phoneme classes and optimum size of code book for phoneme basis recognition environment has been proved by the result of computer simulation.

Wernicke's encephalopathy is characterized by the triad of ocular symptoms, ataxia, and mental confusion and neuropsychiatric condition generally caused by acute thiamine deficiency. Although it is common in the severe alcoholics, several other causes also have been identified, such as total parenteral nutrition (TPN) use, hyperemesis gravidarum, anorexia nervosa, hemodialysis, uremia, and acquired immunodeficiency syndrome(AIDS). Chemotherapy in patient with malignanacy and long term total parenteral nutrition following bone marrow transplantation are related with Wernicke's encephalopathy. A 48-year-old woman had been treated with Daunorubicin and Cytarabine for remission induction chemotherapy of acute myeloblastic leukemia and intravenous hyperalimentation due to persistent hematochezia and ileus caused by infiltration of leukemic cell in terminal ileum. She suddenly complained of diplopia, tremor, and mental confusion at 32th day after chemotherapy and generalized tonic-clonic seizure at 34th day after chemotherapy. The diagnosis of Wernicke's encephalopathy was made with clinical presentations and brain MRI. Brain MR T2-weighted & Flair image revealed a high signal intensity lesions bilaterally at the medial thalamus and peri-acueductal grey matter of the midbrain. The patient was successfully treated with vitamin B1. We presented a case of acute Wernicke's encephalopathy developed after remission induction chemotherapy followed by intravenous hyperalirnentation in a patient with acute myeloblastic leukemia.

『무정』의 계보 : 『무정』의 정본 확정을 위한 판본의 비교 연구

이광수의 장편소설『무정』은 단행본으로 출판되는 과정에서 편집자에 의해 심하게 훼손되고 변개(變改)되었다. 신뢰할 만한 정본(定本)이 부재한 상태에서 그동안의 연구자들은 변개의 양상이 가장 심한 1962년도 삼중당 전집의 『무정』을 텍스트로 사용하였다. 이러한 현실이 『무정』연구의 질적 발전을 가로막았다. 이 논문은 이러한 사정에 주목하여, 1917년『매일신보』에 연재된 최초의 『무정』으로부터 가장 최근에 출판된 『무정』에 이르기까지 모두 아홉개의 판본을 검토하였다. 이 검토를 통하여 식민지 시대에 출판된 『무정』의 간행 상황과 그 판본들의 차이, 1956년 광영사에서 간행된 『무정』에서 가장 심한 훼손이 이루어진 사실, 그 이후 아무런 의심 없이 이 판본이 연구용 텍스트로 사용되어 온 사실 등이 밝혀졌다. 1990년대 이후 『무정』이 정본을 출판하기 위한 몇몇 시도가 있었지만, 그것 역시 오류가 많은 것들이어서 정본이라고 할 수 없다. 이 논문에서는 보다 완벽한 『무정』정본의 간행을 위해 기왕의 주요 판본들을 비교 검토하였고, 이에 따라 『무정』정본의 출판을 위한 기본적인 조건들이 마련되었다. A lot of paragraphs of Yi Kwang-Soo’s novel MuJeong had been changed and even spoiled by editors while it was published Many researches have used MuJeong SamJungDang Co. 1962 as an original text, which was most severely spoiled by editors. Reflecting upon this situation, we have scrutinszed nine texts, that is, from the first serialized MuJeong in Maeil Shinbo 1917 to the last one which was published most recently. From this scrutiny, we came to know not only many differences among the texts but also the fact that MuJeong has been published eight rimes during colonial era. Allthough there have been several tries to publish the original text of MuJeong since 1990’s they also include a lot of errors. From the scrutiny of this paper, we would be provided with the fundamental materials for the more complete text MuJeong.

TALP-35 purified from human term placenta is known to increase microtubule polymerization and stabilize the polymerized microtubule. To examine the effect of TALP-35 on immune system this study was performed. MTT assay was performed to investigate the effect of TALP-35 on the proliferation of RAW264.7 cells. TALP-35 dose dependently suppress the proliferation of RAW264.7 cells at high concentration (above 1 μM) in unstimulated cells, in case of 10 μM TALP-35 treated cells the suppression was 25% but in stimulated cells it was only 15%. Cosedimentation assay was carried out to investigate whether TALP-35 can bind to tubulin of RAW264.7, monocyte/macrophage lineage of mouse, and polymerize it. TALP-35 polymerize the tubulin of RAW264.7 cells and sedimented in dose-dependent manner. To investigate the effect of TALP-35 on the expression of iNOS protein western blotting was performed. The expression level of iNOS was decreased dose dependently in high concentration of TALP-35 treatment. To examine the activity of iNOS, secreted NO was determined by method based on Griess reaction. Interferon-γ and LPS-stimulated production of NO from RAW264.7 cells was decreased dose dependently above 0.1 μM concentration of TALP-35 and 50% is decreased at 10μM of it. This study shows TALP-35 can control cytokine induced-iNOS expression therefore it might control inflammatory diseases.
