This is to review the surgically assisted rapid maxillary expansion followed by orthodontic treatment for malocclusion with maxillary narrow-arch. Two patients who presented with narrow-arch maloccluson and transverse maxillary deficiency underwent a Lefort I osteotomy extending to the zygomatico-maxillary but-trees and splitting of the midpalates. Orthopedic expansion was initiated with one complete rotation 0.8㎜ of the expansion screw on the day, and followed by two quarter-turn 0.4㎜ each day thereafter untill the arch expanded to preplanned level. Changes of the mid-incisal gap space. intermolar width. incisal inclination, TMJ symptoms and reapse tendency were examined periodically. After the surgico-orthodontic leveling and alignment. pre-planned orthognathic surgeries (maxillary & mandibular osteotomies) were rendered to correct the maxillofacial deformites. Results:Intermolar width (IMW) was increased to 13㎜ within 20 days and the gap between to cen-tral incisors was declined to5-7^。. There were neither complaints nor signs of TMJ disorders during treatment. The amount of relapse was less than 0.5㎜ in a year. Therefore, the surgically assisted rapid palatal expansion(SARME) can be a pre-orthodontic option to gain the interdental space in narrow-arch malocclusion with crowding and to reduce the labial inclination of upper incisors without extraction of premolars.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

미래 사회를 대비하기 위한 개인의 개성을 존중과 창의적인 능력을 지닌 인간을 양성을 목적으로 충청남도 지역의 초 ㆍ 중고등학생들을 대상으로 한 창의력 경연대회가 공주대학교 과학교육연구소에서 개최되었다. 충청남도 초 ㆍ중 ㆍ 고등학생들을 대상으로 실시한 창의력 경연대회는 창조적 아이디어를 내어 스스로 문제를 해결해 나갈 수 있는 교육 프로그램을 제공하는 좋은 기회였음이 확인되었으나, 일부의 팀에서만 참신하고 재미있는 아이디어들이 제안되었다. 여학생의 참가자 수가 상당히 증가하였으며, 대체적으로 입상권의 학생들의 상당 부분이 여학생이라는 것이 특이할만하다. 학년이 올라감에 따라서 창의적인 아이디어를 내는 양이나 질에 있어서 뒤떨어지는 것으로 분석되었으며, 토론 학습의 적응력이 미흡하고 발표력 및 청취력에 있어서도 떨어지는 것으로 나타났다. 따라서 중 ㆍ고등학교의 학교교육에서도 학생들에게 프로젝트형 탐구학습 프로그램의 적용은 물론 토론식 수습을 통한 학생들의 사고의 전환의 기회를 제공해야 할 것으로 사료된다. The creativity competition was held to foster the creativity of elementary and secondary school students in the Institute of Science Education, Kongju national University. It was found that the creativity competition effected on the improvement of inventing creative ideas and problem solving activities. But, only some competitors participated in semifinal and final contests, presented original and interesting ideas. More female students participated in competition than last year. More female participants were awarded a prize than males. Totally, participants were defective in discussion and communication, and presentation and listening ideas. Increasing grades correlated inversely with creativity and originality. There is need of inquiry project teaming programs and presenting opportunities of conversion of thinking by discussing instructions in school

LiNbO₃결정내의 [Li]/[Nb] 성분비에 따른 물성 변화

김상수,김두회 昌原大學校 基礎科學硏究所 1997 基礎科學硏究所論文集 Vol.9 No.-

A series of LiNbO₃single crystals with different [Li]/[Nb] ratios from melts having compositions varing between 48.6∼58.0 mol % Li₂O and a congruent melt with the addition of 6 wt. % K₂O were grown by the Czochralski method. A vapor transport equilibration(VTE) technique has been used to improve the homogeneity and adjust the [Li]/[Nb] ratio. These were investigated by Electron Paramagnetic Resonance(EPR), UV-and IR-spectrophotometry. The characteristics of the EPR spectra depend on the crystal field at the ?? sites, which in turn are influenced by the composition. In the VTE single crystal only the allowed transition takes place, having a very narrow width and symmetrical shape. The position of the fundamental absorption edge of LiNbO₃is a sensitive indicator for the [Li]/[Nb] composition of the single crystal. A pronounced blue shift occurs if the Li content rises. The decompositiom of the ?? vibrational bands using a Gaussian line shape function showed that in Li-dificient crystal the absorption bands consist of five(3465.9, 3469.5, 3480.8, 3489.4, 3500.6 ??) components in contrast to more or less perfect stoichiometric crystals which reveal to three(3465.8, 3469.7, 3481.1 ㎝??) components. When equilibrated which a Li-rich powder(65 mol % Li₂O), containing a mixture of LiNbO₃and Li₃NbO₄, crystal of nearly stoichiometric composition can be obtained.

Self - protective Activity of Colostral IgA Globulin from Tryptic Digestion

Kim, Woo Jung,Kang, Yoon Se,Shim, Bong Sop,Cho, Sung Hoon,Lee, Du Bong 생화학분자생물학회 1971 BMB Reports Vol.2 No.2

Although the amount of IgA in serum is small compared with the amount of IgG, IgA is redominant in secretory fluids such as colostrum, saliva, nasal fluid and tears. IgA from the colostrum and saliva has a higher sedimentation constant (11S) than serum IgA(7S), and 11S colostral IgA has additional antigenic determinants with specificities which are not present in serum IgA. In addition to the heavy and light chains present in the molecule of serum IgA, colostral IgA has another protein component-the transport piece or the secretory piece. Immune globulin in colostrum accounts for the immunity to certain infections acquired by newborn mammals after suckling. After hydrolysis in the gut, proteins in the form of aminoacids are thought to be absorbed, but there is -no experimental evidence for this. We have therefore studied the problems as follows. Colostrum was collected after delivery from primiparous women, and colostraI IgA was purified by gel filtration with Sephadex G-200 and DEAE-cellulose chromatography according to the method of Cebra and Robins. Antitryptic activity was measured in two ways. First, the inhibitory capacity of whole colostrum against trypsin was performed as described by Faarvang using urea-denatured bovine hemoglobin solution as substarate. Fifty microliters of a 0.2 per cent solution of crude trypsin was warmed at 25 for 20 minutes in a water bath. One hundred and fifty microliters of fresh whole colpstrum, prewarmed to 25 or 150 microliters of human serum was added to the above prewarmed enzyme solution. Two minutes later 0.5 ㎖ of 22 per cent urea-denatured bovine hemoglobin solution and 100 microliters of 0.1 M phosphate buffer, pH 8.0, were added, and the mixture was incubated for 20 minutxs at 25° The undigested protein was then precipitated by 2.5 ㎖ of 0. 3 M trichloroacetic acid. After the mixture had been centrifuged or filtered, 50 microliters of the supernatant was used for the Folin-Ciocalteu reaction. Trichloroacetic acid was added to the blank before addition of the hemoglobin solution, and the absorbance was read at 700 mmicrons with a Beckman DU-2 spectrophotometer. The second method which we followed was as described by Kueppers and Bearn. One part pf 0. 1 per cent bovine fibrinogen in 0.1 M phosphate buffer, pH 8.0, ,was mixed with ten parts of 2 per cent hot agar (80-90°in 0.1 M phosphate buffer, pH 8. 0. On mixing the fibrinogen with hot agar the mixture immediately turned cloudy and it was poured onto a glass slide which was kept in a moist chamber for one hour. A longitudinal strip of agar, 3 mm wide, was then cut out to make a trough, and near the trough two wells, 0.4 mm ;in diameter, were punched out of the agar. The trough was filled with 0.2 per cent crLde trypsin solution in 0.1 M phosphate buffer, pH 8. 0. One hundred microliters of fresh human colostrum or isolated colostral IgA or fresh human serum were introduced side by side into the wells and the slide was left overnight at 40 in a moist chamber. After washing the slide with 0.15 M NaCl to remove the digested fibrinogen peptides, it was stained with amidoblack 10B. Using hemoglobin as substrate, colostrum-unlike serum-did not show antitryptic activity. When, however, either colostrum or colostral IgA was tested using the fibrinogen-agar-gel slide technic, it showed antitryptic activity similar to that shown by serum. The discrepancy between the two results can be explained as follows. Serum antitrypsin acts. directly on the trypsin molecule, thus protecting every kind of protein molecule from tryptic digestion. Colostral IgA on the other hand has only self-protecting activity against trypsin. Thus when hemoglobin was used as substrate there was no antitrypticactivity, whereas in the fibrinogen-agar-gel slide technic antitryptic activity was evident because colostral IgA which cannot be digested by trypsin diffused through the fibrinogen-agar medium. From the theoretical point of view also, colostral antibody should not interfere with the digestion of other nutritionally important proteins in the milk and. it should have only self-protective action for absorption or for its biologic activity in the gut. The presence of antitrypsin in colostrum was thought to aid passive alimentary immunity by delaying they hydrolysis of antibody. Chamberlain and others, however, failed to show the absorption of gamma globulin intact in piglets after experimental addition of antitxypsin. It may be then that passive immunity is aided only by the antitryptic activity of specific, intrinsic colostral IgA. At the present time we do not know whether the whole intact IgA molecule or only that part which retains the antibody activity is protected from tryptic digestion. Serum IgA and. colostral IgA differ in the presence of the so-called transport piece in the calostral IgA molecule. We have demonstrated the presence of the additional protein component in the colostral IgA. by gel filtration of reduced and alkylated colostral IgA, so it seems reasonable to assume that one possible function of the transport piece is to protect the molecule or the part of the molecule which has the antibody activity from proteolytic enzymes in the gut. Direct demonstration of the antitryptic activity of the transport piece is now under progress.
