Background and Objectives : Many students major in applied music singing have various difficulties in phonation when they sing or perform. But the studies about this cause are lack. The purpose of this study is whether singing voice therapy based on vocal music is effective or not to applied music singing students that have difficulties in phonation. Materials and Methods : Singing voice therapy program had been done to 8 students major in applied music singing during 7 weeks. We did laryngeal stroboscope, perceptual, acoustic and aerodynamic examination before and after singing voice therapy to this students. And we studied post examination results have differences or improvements compared to pre examination results. Results : Four male students don't have effective improvement after singing voice therapy but they shows slight improvement in aerodynamic examination values compared to pre examination values. Four female students shows improvement in aerodynamic examination values and pitch range increasing. Above all, one student's vocal nodules disappeared after singing voice therapy. Conclusion : Singing voice therapy based on music singing is very effective to the students major in applied music singing. Above all, their curriculum in applied music singing should include phonation training based on music singing before training perform and technic practices.

본 연구는 사춘기 성장 이전의 I, II급 부정교합을 갖는 아동 환자들의 측모 두부 규격 방사선사진을 이용하여 두개 안면 형태를 조사하고 이들과 혀의 위치 및 면적, 기도의 면적과의 관계를 조사하여 비인두 기도 및 혀의 형태가 악골 및 부정 교합의 형태에 미치는 영향을 알아보았다. 9 - 11세의 교정환자 76명을 대상으로 측모 두부 규격 방사선사진상 ANB difference를 기준으로 대조군(I급 부정교합군: 0 ≤ ANB difference < 4.0)과 실험군(II급 부정교합군: ANB difference ≥ 4.0)으로 분류하였다. 혀 면적, 혀와 구개 사이의 면적, 비인두 기도 면적과 두개안면형태 항목을 측정하고 비교하여 다음과 같은 결과를 얻었다. 혀 면적, 혀와 구개 사이의 면적, 비인두 기도 면적은 II급 부정교합군과 I급 부정교합군 간에 유의한 차이를 보이지 않았다. Hyperdivergent안면 형태일수록 비인두 기도 면적이 좁았다. 안모의 전후방 수직 길이가 길수록 혀의 면적이 넓었고, 전안면 고경이 길수록 혀는 하방위치 하였다. 비인두기도 면적이 좁을수록 혀의 면적도 좁아졌다. 이상의 연구 결과 혀의 면적과 위치, 비인두 기도의 면적은 I급, II급 부정교합 간에 차이를 보이지 않으며 hyperdivergent 안면 형태 및 안모의 전후방 수직 길이와 관련이 있는 것으로 사료된다. Objective: This study examined the craniofacial morphology of young patients in their prepubertal stage showing class I, II malocclusion, by analyzing lateral cephalograms, and analyzed its relationship with tongue position, tongue space, and airway space in order to ascertain the effects of nasopharyngeal airway and tongue morphology on the form of the malocclusion. Methods: Seventy-six patients aging from 9 to 11 were divided into two groups depending on the ANB difference on the lateral cephalogram: Experimental grouP (CI II malocclusion group) showing 0 ≤ ANB difference < 4.0; Control group (CI I malocclusion group) showing 0 ≤ ANB difference < 4.0. The tongue space, space between palate and tongue, nasopharyngeal airway space and craniofacial morphology were compared between the two groups. Results: Tongue space, Palate-tongue space, nasopharyngeal airway space showed no significant differences between class I and class II malocclusion groups. Hyperdivergent faces were associated with smaller nasopharyngeal airway space. Longer anterior facial height and posterior facial height were associated with larger tongue space, and greater anterior facial height were associated with lower tongue position, Smaller nasopharyngeal airway space showed smaller tongue space. Conclusions: Tongue space and nasopharyngeal airway space showed no significant differences between class I malocclusion group and class II malocclusion group. Only anterior facial height and posterior facial height had an influence on tongue space and nasopharyngeal airway space.

To improve the therapeutic method for mastitis, treatment effect of chitosan pharmacopuncture was examined in three milking goats(A,B and C). Mastitis was artificially induced in two milking goats(A and B) and one goat(C) was naturally infected case with mastitis. The acupoint used was Yang-Ming and chitosan suspensions(provided from Tottory University, Japan: 30㎎ of chitosan/㎖)were injected to the acupoint with 5㎖/time for 3 days, respectively. As for the change of somatic cells in milk along with chitosan pharmacopuncture, they showed a decreasing tendency after increase on the 3rd day in all udders of B. In addition, as for the change of total leukocyte counts of peripheral blood with chitosan pharmacopuncture, they showed a decreasing tendency after increase on the 3rd day in B and C except A which showed a increasing tendency until on the 7th day. In the change of neutrophil/lymphocyte(N/L) ratio, increasing tendency was seen in A and C but increasing tendency after slight decrease was observed in B. Further, in the change of serum total protein and A/G ratio, serum total protein content was decreased after slightly increase on the 3rd day in A, and they were decreased after increase until on the 7th day in B and C, respectively. As for the change of A/G ratio, different pattern increasing tendency was shown in A, B and C.

Background and Objectives: We previously reported that, compared with standard cardiopulmonary resuscitation(S-CPR), better hemodynamic effects could be achieved by simultaneous sterno-thoracic cardiopulmonary resuscitation(SST-CPR) in which we compressed the sternum and constricted the thorax circumferentially during the systolic period by using a device. This study was designed to assess whether SST-CPR, compared with S-CPR, improve the survival rate of dogs with cardiac arrest. Subjects and methods: Twenty-five mongrel dogs(19∼31㎏) were enrolled in this study. After four minutes of ventricular fibrillation induced by an AC current, animals were randomized to resuscitate with either S-CPR(n=13) or SST-CPR(n=12). Epinephrine(1 ㎎) was injected into the right atrium every three minutes after the beginning of CPR. Defibrillation was attempted after 6 minutes of CPR. Standard advanced cardiac life support was started if defibrillation was not successful. Results: SST-CPR resulted in significantly(p<0.001) higher systolic arterial pressure(91±47 vs 47±24 ㎜ Hg), diastolic pressure(43±24 vs 17±10 ㎜ Hg), coronary perfusion pressure(35±25 vs 13±9㎜ Hg), and end tidal CO2 tension(9±4 vs 3±2 ㎜ Hg). Two of 13 animals(15 %) resuscitated with S-CPR and six of 12 animals(50%) resuscitated with SST-CPR survived until 12 hours after cardiac arrest(p<0.05). Donclusion: SST-CPR, compared with S-CPR, improves the short-term survival rate in canine cardiac arrest.

청피홍심무우를 재료로 A. rhizogenes A₄균주를 접종하여 hairy root를 유도하였으며 유도된 hairy root는 paper electrophoresis를 통하여 mannopine과 agropine이 검출되어 형질전환 되었음을 확인하였다. Hairy root는 MS의 기본염을 1/2로 희석시킨 1/2 MS, sucrose 3%, pH 5.2로 조성된 배지에서 최적인 성장을 보였다. 유도된 hairy root는 각 strain사이에 색소능에 다소간의 차이를 보였으며 2, 4-D kinetin의 적절한 조합의 처리구에서는 탈분화와 더불어 색소가 형성되었고, 그 중 2, 4-D와 kinetin을 각각 1 ppm, 5 ppm 처리하였을 때 최대 색소능을 보였다. hairy root의 탈분화시 형성되는 색소는 원 식물 뿌리의 주 색소인 pelargonidin 계열의 색소로 추정되며 총 색소량은 49mg/100g(F.W.)로 잠정 계산되었다. Hairy root induced following inoculation of the root disc and plantlet fragment of R. sativus Var Chungpihongsim with A. rhizogenes A₄. The hairy root contained agropine and mannopine. Medium contained 1/2 MS salt, sucrose 3%, pH 5.2 was optimized to growth of hairy root. Depending on the hairy root line, the level of pigment in hairy root varied somewhat . When 2, 4-D and kinetin were added in hairy root, the synthesis of pigment induced with deorganization of hairy root. Especially, addition of 2, 4-D 1 ppm and kinetin 5 ppm showed the maximum synthesis of pigment. Compared with anthocyanin extract of mature root three pigments were assumed to acylated pelargonin. The content of anthocyanin in these sample was 49mg/100(F.W.).

Electrophoretic variations in isozymes encoded by 16 loci were studied to estimate genetic variation and to assess phyletic relationships, and biogeographic pattern of distribution of the Euphaedusa fusaniana collected from Sehwa, Aeweol, Samchuck, Tongdosa, Gernundo, and Y?su areas in Korea was discussed with respect to the isozyme variation. The 180 apecimens were examined. Means of allele per locus(?) and polymorphism(?) were 1.528 and 45.5%, respectively and hetrozygosity (?_(D)) was 0.205. Samchuck population showed lower mean value of allele per locus(?=1.46). Higher polymorphism(P=57.14%) was observed among Tongdosa popualtion. Aeweol population showed slightly lower genetic variation (H_(D)=0.15) than others. Average genetic similarities(?) among the six populations was 0.716 Aeweol and Samchuck populations were genetically closer(S=0.903) than others. However the S value between Y?su and Samchuch populations was low(S=0.562). Average genetic distance(?) among the 6populations were 0.267. Both Aeweol and Samchuck populations have closer genetic distance (D=0.067). Genetic distance pattern was similar to genetic similarity pattern.

The current study was designed to evaluate the positive rates of arthropod allergens by Korean inhalant panel of MAST-CLA in patients with allergic rhinitis. One hundred sixty patients, diagnosed to allergic rhinitis in an Out Patient Center of Soonchunhyang University Chunan Hopsital during Aug 1998 to July 2000, were studied. 1. The overall positive rate among 35 specific allergens was 59.4% (95 patients). 2. The arthropod related allergen accounted for 82.1% (78 patients) of the positive rate. 3. Each positive rate of Dermatophagoides farinae (Df), Dermatophagoides pteronyssinus (Dp), house dust (Hd), and cockroach mix (Cm) was 45.0% (72 patients), 43.1% (69 patients), 28.1% (45 patients), and 8.8% (14 patients), respectively. 4.Significant agreement between arthropod allergens was observer (P < 0.05). 5. The obseved agreement between Df and Dp was 95.6%, showing most significant Kappa index (Kappa = 0.911, P < 0.001). There results suggested that although MAST-CLA is a useful measure of identifying specific allergens, the specificity of two mite allergen relatively low, implying because of common allergen between mites in Korean panel of MAST-CLA. Our data also supported that arthropod is the major cause of allergen in patients with allergic rhinitis, however, the MAST-CLA should be modified in order to exclude common allergen of mite and to include more specific mite allergen.
