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.

Polishing is one of the important processing having influence on the surface roughness in manufacturing of Si-wafers. The surface roughness in wafer polishing is mainly affected by the many process parameters. A feed forward neural network model is developed exploiting experimental measurements from the surface in wafer final polishing. The input variables of Neural Network model are process parameters. The output variables are measured surface roughness. The neural network model is trained and performed by MATLAB. The model can be used for the analysis and prediction of the complex relationship. From this, it is clearly seen that a good agreement is observed between the predicted values and experimental measurement values.

This study was conducted to examine aspects of health service availability and the satisfaction level of clients of public health centers. 351 clients who visited health centers located in Kyungsan, Chongdo, Youngchon, Kyungju, and Pohang were selected as subjects of this study. Data were collected from March 2, 2000 to April 15, 2000. The results of this study are summarized as follows. 1. 89.5% of them had experience in utilizing health services in public health centers. The rate of availing themselves of public health centers by their own decisions was highest (49.4%). 39.8% of them replied that it took below thirty minutes to visit public health centers. 42.2% of them visited public health centers to be vaccinated. 38.0% of them wanted Oriental medicine to be introduced in public health centers. 30.7% of them thought that doctors need go and see patients at their houses and 31.6% of them was satisfied with present office hours. 39.2% of them was not satisfied with the health services because public health centers were ill equipped. 65.1% of them received medical care in public health centers due to low medical charge and 91.0% of them replied that they would visit again public health centers. 35.5% of them thought that medical equipments must be increased to improve health services of public health centers. Each of the above rates were highest in each variables. 2. According to the satisfaction level with health services of public health centers, 35.2% of them was satisfied, while 9.0% of them was not satisfied. 5.7% of them was very satisfied, while 3.0% of them was not satisfied at all. 47.0% of them was satisfied only to a usual extent. 3. The variables, which significantly influenced the satisfaction level with availability of public health centers, were 'reliance on the medical staff (b=0.1749)', 'sufficiency of nurse's explanation (b=0.2093)', 'medical technician's kindness (b=0.1557)', 'simplicity of medical care procedure (b=0.2036)', 'level of medical charge (b=0.1393)', and 'satisfaction with effect of treatment (b=0.1690)'. 4. The variables, which displayed significant correlation with the satisfaction level with availability of public health centers, were 'necessity of doctor's visit to patients' houses (r=0.229)', 'reliance on the medical staff (r=0.488)', 'sufficiency of doctor's explanation (r=0.495)', 'nurse's kindness (r=0.441)', 'sufficiency of nurse's explanation (r=0.458)', 'medical technician's kindness (r=0.326)', 'the staff's kindness in civil service office (r=0.352)', 'simplicity of medical care procedure (b=0.338)', 'environment of waiting room (r=0.283)', 'convenience of availability of subsidiary facilities (r=0.275)', 'level of medical charge (r=0.335)', 'location of public health center (r=0.173)', 'medical facitities and equipment (r=0.217)', 'treatment methods (r=0.294)', and 'treatment effect (r=0.359)'. It appeared that the community residents were somewhat unsatisfied with public health centers because of problems of equipment, treatment sphere, treatment procedure, and medical personnel. Therefore. The government must focus on increase and modernization of medical equipments, the establishment of oriental medicine, and increase of medical personnel. It is important for public health centers to provide community residents with better health services in order to meet their health needs.

벼와 피에서 제초제 alachlor의 선택적 작용

황을철,우승희 東亞大學校生命資源科學大學附設 農業資源硏究所 1995 農業生命資援硏究 Vol.4 No.1

벼와 피에서 α-chloroacetamide계 제초제의 선택적 작용, 특히 포장에 이앙하는 어린모의 벼(약 40일묘)와 발아중인 피에서 alachlor의 선택적 작용이 발현되는 근거를 찾고자, 벼와 피에서 몇가지 생화학적 차이를 조사하였다. 제초제 alachlor에 의한 약해는 생장일수가 동일한 유묘기의 벼와 피에서는 비슷하였으나, 생장일수가 서로 다른 40일묘의 벼와 7일묘의 피에서는 현격한 차이가 있었다. Alachlor에 대하여 약해정도가 현격히 다른 40일묘의 벼와 7일묘의 피체내의 GSH 함량과 GST 활성은 서로 비슷하였으며, alachlor 처리에 의한 GSH 함량과 GST 활성의 증가도 모두 미미하였다. 40일묘의 벼와 7일묘의 피에서 alachlor 처리에 의해 저해되는 α-amylase의 활성은 무처리에 비해 각각 93.5%와 70%로 현격한 차이를 나타내었으며, 이는 약해정도와 부합하였다. 따라서, 40일묘의 벼와 7일묘의 피에서 발현되는 alachlor의 선택성 또는 벼를 이앙한 포장에서 발아중인 피를 방제하는 α-chloroacetamide계 제초제의 선택성은, 벼와 피체내의 방어계인 glutathione conjugation 반응에 기인하는 것이라기 보다는, 종실내의 주된 저장영양분인 탄수화물의 이용에 관련된 효소인 α-amylase가 저해되는 정도에 기인하는 것으로 판단되었다. Several biochemical differences between rice and barnyardgrass which were related to glutathione conjugation and utilization of starch reserves in seeds were examined to investigate the selectivity of α-chloroacetamide herbicides in rice and barnyardgrass, especially in transplanting staged rice (about 40-day-old) and germinating barnyardgrass. Phytotoxicities of alachlor to rice seedlings and barnyardgrass seedlings were all severe at stronger concentration that 1.0×10-6 and were similiar to each other at various concentrations. However, 40-day-old rice which was independent on the seed reserves was tolerant to alachlor. Glutathione(GSH) content and activity of glutathione S-transferases(GST) in roots of rice seedlings and barnyardgrass seedlings were similiar to each other, and those of 40-day-old rice and barnyardgrass seedlings which were observed to show different responses to alachlor were so. Moreover, the inductions of GSH and GST in 40-day-old rice and 7-day-old barnyardgrass following treatments with 1.0×10-5 solution of alachlor were insignificant. On the other hand, activities of α-amylase in seeds of 40-day-old rice and 7-day-old barnyardgrass following treatments with 1.0×10-5 solution of alachlor decreased to 93.5% and 70.0% of the control respectively. These results were consistent in phytotoxicities above stated. It was therefore stated that the selectivity of alachlor, α-chloroacetamide herbicide in 40-day-old rice and germinating barnyardgrass was due to inhibition degree of α-amylase needed for starch utilization as energy sources in grass germlings, rather than due to the rate of glutathione conjugation generally considered as main factor contibuting to α-chloroacetamide herbicide detoxification and selectivity.

The purpose of this study is to identify the scientifical idea of human body in the Enlightening Period in the light of beginning and development of modern gymnastics of Korea with the conflict between traditional thoughts and the western thoughts. Therefore, I tried to clarify the process of the formation and development of Korean gymnastics in the fluctuation of the end of the Dai Han Empire by examining the scientifical idea of human body on anatomy and physiology of the pioneers in the Enlightening Period. As a method of study, Literature approach, the analysis of academic journals of those days was taken as a method of this study. The results of this study can be summarized as below. Anatomy and physiology related to physical exercise, especially anatomy and physiology of human body, was systematically studied. The concept of physiology was established and Heon-Suk Song and 'the monthly bulletin of Buk Seo Academy' detailed the physiology of human body. But the relationship between physiology and gymnastics was poorly explained expert the explanation of the relationship of the number of respiration and the physical status, age, motion, and temperature in 'the Introductory Respiration Physiology'.

Marine organisms such as fish (Sebastes schlegeli) and mussels were cultured in sea water tanks placed at Dukpo area which was contaminated by the two oil spill accidents. Results showed that PAHs concentrations in fish tissue were higher than in fish liver. This was explained by the cytochrome P450 IA induction in fish liver after PAHs exposure. Other studies showed that higher PAHs levels were detected in mussels cultures in oil contaminated area than in control site. From these results, we concluded that Dukpo area is still polluted by oil including PAHs and it takes a long time to recover of oil contamination after the oil spill accidents.

An Art creates the aesthetic effect through the beauty of form rather than its contents. It is important to perceive how the art exists and functions in the society. The aim of art is to create a true outer form by taking a rational thing out from the inside through the medium of the spiritual activity. Craft concept of the transience of the physical world has very different consequences. The word 'Art' is to be used when it becomes meaningful in the process of an individual transfusing his thought into the senses of others. Aesthetic of art by the style of Modern have generally favoured what has been called the theory of functionally Art. The matter of description of beauty and the interpretation of beauty qualities is based for instance on this double standard. Thus, the aesthetic of Art and functionally art tell us quite a lot of what's going on in our century.

經口的 慢性暴露에 의한 白鼠의 Methyl 水銀 中毒時 마늘의 豫防效果에 關한 硏究

黃正一,裵恩相,車喆煥 고려대학교 의과대학 1986 고려대 의대 잡지 Vol.23 No.1

Many researches on the various chemical compounds which containes -SH radicals including BAL and penicillamine have been undertaken in order to develop proper ways of treatment and protection from methyl mercury poisoning. However, BAL and penicillamine which have been used for these purposes, are still remained as a pending issue because of the side effects, and the studies on their derivatives hare been conducted to clarify whether these chemical compounds of -SH radical bring about protective effect to brain and kidney: the target organs of mercury phoning although still uncertain. Therefore, the authors tried to inquire into the protective effects of the Korean garlic against the methyl mercury poisoning. The Korean garlic has been known as a vegetation which has a protective effect and contains a large amount of diallyldisulfide with -S-S and -SH radicals such as glutathione, cysteine, homocysteine and etc.. The garlic was put into pellet by various concentrations, and methyl mercury was mixed in drinking water by 4 ppm concentration. These mixture were fed to albino rats for 10 weeks. A close observation was made to see the histopathological changes and amount of mercury accumulation in brain and kidney. At the same time, the amount of mercury accumulation in liver and erythrocyts n-ere compared with control gorup. The results of the experiment were as follows; 1. In simultaneously-dosed group with 6.7% garlic and methyl mercury, concentrations of mercury in organs were lower than those in methyl mercury-only-dosed group by 33.1% in erythrocyte, 32.2% in brain, 22.3% in liver and 29.1% in kidney. The group with 8.0% of gallic and methyl mercury also showed lower concentration by 38.6%, 41.9%, 39.5% and 34.3% in those organs respectively, whereas there was PO significant difference between the group with 2.35% of garllic and methyl mercury and that of methyl mercury-only-dosed group. 2. The simultaneously-dosed group with 3.35% of garlic and methyl mercury didn't show a remarkable difference to the group treated with methyl mercury-only in histopathological findings of brain and kidney. However, for the group with 6.7% of garlic and methyl mercury, a slight demyelinization in cerebellar white matter and degenerative change of Punkinje cells were found. In addition, a little degeneration on epithelium of proximal tubules in kidney and a small amount of- tubular casts were found. The-group with 8.0% of garlic and methyl mercury has shown a loss of small amount of demyelinization in cerebellar white matter, but kindey was remained in normal architecture. Accordingly, simultaneous administration of garlic with methyl mercury caused decrease. of mercury accumulation in erythrocytes, brain, liver and kidney and it also has shown protective effect in histopathological changes in brain and kidney. The result also makes us. to believe that there exists some evidence of dose-response relationship between the amount. of Korean garlic dosed and its protective effects on methyl mercury.

Aplasia cutis congenita is a disorder of heterogeneous group characterized by isolate or multiple, localized or widespread areas of skin defect at birth. Since the first report by Cordon in 1767, it has been relatively rarely reported disorder abroad as well as domestically . It has several clinical subtypes classified by the location and pattern of skin absence, the presence of associated malformations and the mode of inheritance with unknown cause. We had a newborn male infant with this disorder clinically diagnosed, who showed wide full thickness skin defects on right knee and medial surface of ankle from birth, that covered with thin yellowish membrane and showed focal ulcerative area. On his familial history, there were four aplasia cutis congenita patients in the patient's mother in his maternal family side through four generations. Patient mother showed wide spread atrophic scarred looking appearance on her right lower leg. Chromosomal analysis revealed as normal male karyotype. The biopsy of lesions showed ulcerated surface and underlying chronic inflammation with total absence of epidermis. He had no associated congenital anomaly. The lesions healed rapidly for four weeks by conservative treatment as moist wound dressing and systemic antibiotic administrations. As a relatively uncommon skin anomaly, one case of aplasia cutis congenita is reported with review of references.
