Various volume of water for the optimal brewing condition of the Korean distilled liquor produced by liquefaction of rice and corn starch was investigated Pilot brewings were carried out by the liquefaction of 5㎏ of rice and 10㎏ of corn starch with 150%, 200% and 250% of water regarding the amount of rice and corn starch. The pH, alcohol production and total acidity were normal during the fermentation process. The yield was proportional to the amount of water added and the highest yield was obtained by 250% of water addition without loss of quality. All the test results were not significantly different by the one-way ANOVA and Duncan's multiple range test at p<0.05 and the flavor profiles were also not different according to the amount of water added. As a result, 250% of water addition was the most economical and optimal brewing condition in this study.

이차 우식은 수복 실패의 주된 원인 중 하나로 지목되고 있으며, 이로 인해 빈번히 재수복을 하게 된다. 이차 우식은 항우식 작용이 있는 불소를 함유한 수복물을 사용하여 예방될 수 있다. 구강내에서 불소를 유리하는 것으로 알려진 글라스 아이오노머 수복재는 불소를 장기간 유리할 뿐 아니라 불소의 재충전 및 재유리 능력이 있어 불소의 저장소 역할을 할 수 있다. 따라서 본 연구는 통상의 글라스 아이오노머와 고점도 글라스 아이오노머 및 복합 레진을 대상으로 불소의 유리 양상과 불소도포를 통한 재흡수 후 유리 양상을 알아봄으로써 기존의 수복재와 새로운 수복재간의 임상적 유용성을 평가할 목적으로 시행하였다. 4종의 수복재를 대상으로 불소 유리량 및 2% NaF로 재충전 후 불소 유리량을 각각 측정하여 다음과 같은 결과를 얻었다. 1. 실험 대상의 모든 글라스 아이오노머 수복재는 초기에 다량의 불소를 유리하고 이후 점차 감소하는 경향을 보였다. 2. 2% NaF 용액을 통한 재충전 후의 유리량은 Fuji IX, Ketac Fil, Ketac Molar, Z-100의 순으로 나타났다. 3. Fuji IX을 제외한 모든 실험 대상의 수복재에서 수분의 영향으로 표면 경도는 유의하게 감소하였고 불소 재충전 후 유리량은 수분 흡수와 비례하였다(P<0.05). 4. Fuji IX이 초기 유리량에 비해 재충전 후 더 많은 불소를 유리였다(P<0.05). The replacement of dental restorations due to secondary caries is a continuing problem in restorative dentistry. The secondary caries can be partly prevented by using fluoride containing dental materials such as glass ionomer cement, which releases and be recharged with fluoride ion acting as a fluoride reservoir. For the purpose of investigating the behaviors of fluoride release and recharge of conventional and high viscosity glass ionomer cements, the experiment was performed on the seven specimens each from 4 kinds of materials; 1 kind of conventional glass ionomer cement, 2 kinds of high viscosity glass ionomer cements and 1 kind of composite resin. The amount of fluoride release was measured over 7 days with pH/ion meter and fluoride specific electrode. After measuring daily fluoride release, the specimens were recharged with 2% NaF solutions for 4 minutes and measured for 3 days with recharging repeated two consecutive times. The results were as follows : 1. Significantly more fluoride was released at first day after recharge in all materials except Z-100. 2. High viscosity glass ionomer cements released more or nearly equal amount of fluoride after recharge compared with the initial release(P<0.05). 3. The fluoride release after recharge with 2% NaF solution was in order of Fuji IX, Ketac Fil, Ketac Molar, Z-100.

소아치과 임상에서 기성금관 수복은 광범위한 우식병소를 가졌거나 치수치료를 받은 치아에 필수적인 술식으로 간주된다. 그러나 기성금관 장착을 위한 치아 삭제 과정 중 인접 치면에 의원성 손상이 생길 경우 우식이환율이 높아질 수 있다. 특히 제 2유구치에 기성금관을 위한 지대치를 형성할 때 인접한 제 1대구치 근심면에 발생될 수 있는 의원성 손상은 치아 우식으로 진행될 잠재성을 가지게 된다. 따라서 본 연구는 제 2유구치의 기성금관을 위한 지대치 형성과정에서 생길 수 있는 제 1대구치의 의원성 손상의 유형과 정도를 알아보고자 하였다. 부산대학교병원에 내원한 소아들을 대상으로 기성금관으로 소복한 제 2유구치의 원심면을 치간이개용 고무링으로 치간이개를 한 후 리버인상재로 인접면의 인상을 채득하고 주사 전자현미경상에서 관찰하여 의원성 손상의 정도를 확인하였다. 제 1대구치의 근심면이 인기된 시편을 주사 전자현미경으로 관찰한 결과, 약 66.7%에서 다양한 유형과 정도의 의원성 손상을 확인할 수 있었다. 따라서 유구치의 기성금관 장착을 위한 지대치 형성과정에서는, 치간이개용 고무링이나 wedge를 이용한 치간이개, matrix band를 이용한 인접 치면의 보호, 인접면 삭제방법의 수정 등과 같은 의원성 손상을 예방하기 위한 술자의 노력이 필요할 것으로 사료되었다. Preformed stainless steel crown is an useful restorative material for the treatment of badly broken down primary teeth. However iatrogenic damage to adjacent teeth might occur during the process of tooth reduction. Such damages might lead to plaque accumulation and increase the risks of caries initiation. Especially the damage can make a problem in the first permanent molar. Purpose of this study was to investigate an iatrogenic damage to the first permanent molar during preparation of second primary molar for preformed stainless steel crown. Twelve children restored with preformed stainless steel crown to second primary molar were selected. Contact areas were separated with separation elastics, and tooth surfaces were cleaned. After taking negative impression using vinylpolysiloxane impression material, the specimens were examined by scanning electron microscope for the detection of iatrogenic damage. The prevalence of iatrogenic damage was 66.7% and variable appearances and So we can suggest that when preparing teeth for preformed stainless steel crown, we should be careful about adjacent teeth not to make an iatrogenic damage.

The objective of this paper is to present the new FourCC to use the power of general CPU, to the highest degree, supporting SIMD that is being used the most. This is the form that can be applied to all the picture processing compressed by block. The most ideal form is that the used data is in cache memories of CPU. But the video needs very big memories, so there is little probabilily that the data is in the cache memories. If FourCC suggested in this paper is used, there is always the data in the cache memories. Also, it means that this form can receive profits very much in terms of speed. This paper has simulation using DCT-based vision compression that is the most typical form coding based on block segmentation. We can recognize that the speed improves through this simulation.

연구목적: 정신분열병 환자의 망상에 대한 인지행동치료의 효과를 알아보고자 하였다. 방법: 1999년 6월부터 2000년 9월까지 정신과 병동에 입원된 정신분열병, 정신분열형장애, 그리고 분영정동장애 환자들을 인지행동치료 군과 지지정신치료 군에 무작위 배정하고 10주의 치료기간동안 망상의 확신, 몰두, 그리고 불안의 정도, 증상에 대한 설명방식, 그리고 회복형태를 평가하였으며 두 군간의 결과들을 서로 비교하였다. 결과: 1) 망상의 확신과 불안은 두 군 모두 시간이 지남에 따라 감소하였으나 두 군간에는 유의한 차이가 없었다. 2) 망상의 몰두는 두 군 모두 시간에 따른 감소를 보였고 인지행동치료 군에서 지지정신치료 군보다 현저한 감소가 있었다. 3) 설명방식과 회복형태는 인지행동치료 군에서 지지정신치료 군보다 유의한 긍정적 변화를 보였다. 결론: 인지행동치료는 망상의 몰두, 증상에 대한 설명방식, 그리고 회복형태에 있어서 지지정신치료보다 우수한 치료효과를 가진다. Objectives : The effect of cognitive-behavioral therapy on the delusion in schizophrenic patients was evaluated. Methods : The patients admitted to a psychiatric ward from September 1999 to June 2000 and diagnosed as schizophrenia, schizophreniform disorder, and schizoaffective disorder by DSM-IV were randomly assigned to cognitive-behavioral therapy(CBT) group(n=9) and supportive psychotherapy(ST) group(n=8). During the 10 weeks' treatment period, conviction, preoccupation, and anxiety on delusion, mode of explanation about symptom, and recovery style were regularly measured and compared between groups. Results : 1) As for conviction and anxiety on delusion, the patients from both groups showed gradual reduction over time, but there was no significant difference between groups. 2) As for preoccupation of delusion, patients from both groups showed gradual reduction over time, and the patients on CBT group had a significantly more reduction than ST group. 3) As for mode of explanation and recovery style, CBT group had more marked positive changes than ST group did. Conclusion : Cognitive-behavioral therapy is more effective on preoccupation of delusion, explanatory mode about symptom, and recovery style than supportive psychotherapy.

We aimed to generate basic breeding data for melon (Cucumis melo L.). A total of 219 melon accessions conserved at the National Agrobiodiversity Center (NAC) in Rural Development Administration (RDA) were used in this study, of which 72 (33%) were collected from India. The majority of accessions showed orange (42%) and white (36%) flesh color. In addition to phenotypic evaluations, the accessions were genotyped using a molecular marker for the carotenoid biosynthesis gene CmOr. DNA fragments of the expected size were amplified in 205 out of 219 accessions. Digestion of the PCR products with HinfI restriction endonuclease showed 100% concordance between phenotype and genotype in green-fleshed accessions, but 98%, 97%, and 80% concordance in orange-, white-, and creamy-fleshed accessions, respectively. Sequence analysis revealed single nucleotide changes in the three positions of SNP1, SNP2 and SNP1int in the CmOr gene among accessions. These newly found alleles suggest that there are multiple mechanisms in determining fruit flesh color in melon. Also, the phenotype data of diverse accessions obtained in this study will be a valuable source for melon breeding.

불충분한 시인성에 기인한 안전사고가 연안지역에 많이 발생되고 있다. 그러므로 이러한 안전사고를 방지하 기 위하여 시인성을 겸비한 안전시설이 요구되고 있다. 이와 같은 요구사항을 해결하기 위하여 본 연구에서는 발광체 인입형 콘크리트(LESeCON)의 개념을 정립하고 이를 이용하여 연안지역에 적용하기 위한 콘크리트 경계블록을 개발 및 제작하였다. 개발된 콘크리트 경계블록의 역학적 및 기능적 성능을 검증하기 위하여 휨강도 실험과 시인성 실험을 실시하였다. The safety accidents due to the insufficient visibility are frequently occurred at the coastal zone. Therefore, safety facilities that provide visibility are certainly required to prevent accidents. In order to solve this demand, the concept of the light emitting system embedded concrete (LESeCON) are established and then concrete curb is produced for application to the coastal zone. To investigate the mechanical and functional performance of concrete curb developed in this study, the bending strength test and the visibility test are conducted.

<P>Animals cloned by somatic cell nuclear transfer (SCNT) sometimes have abnormalities that result in large offspring syndrome or early death during gestation due to respiratory and metabolic defects. We cloned pigs using two sources of donor cells and observed phenotypic anomalies in three pigs cloned from one type of cell, s-pig fetal fibroblasts. These animals had many wrinkles on their faces and bodies and looked older than age-matched normal pigs. We performed the present study to examine whether the wrinkled phenotype in the cloned pigs was due to senescence, a genetic problem with donor specificity, or epigenetic problems with reprogramming. To address this issue, we investigated biomarkers of senescence, including telomere length and the expression of senescence-associated β-galactosidase (SA-β-gal), glyceraldehyde phosphate dehydrogenase (GAPDH) and β-actin. We also assessed the methylation status of euchromatic PRE-1 repetitive sequences and centromeric satellite DNA, and measured the mRNA levels of six imprinted genes, Copg2, Mest, Igf2R, GNAS, SNRPN and Ube3a. The telomeres of the wrinkled cloned pigs were much shorter than those of the normal cloned pigs and age-matched normal pigs. In the wrinkled cloned pigs, SA-β-gal activity was detected and GAPDH and β-actin were repressed. The mRNA levels of Mest, GNAS and Ube3a were reduced in the wrinkled cloned pigs, although there was no difference between the normal cloned pigs and normal controls. This gene expression analysis indicates that the wrinkled abnormality of our pigs originates from genetic abnormalities in the donor cells used for SCNT.</P>
