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.

A major defective welding pattern in the steel bridges is identified as the lack of welding area due to the insufficient welding penetration. In this study is fatigue behavior and fatigue life of steel bridge under flange of weld insufficient of butt weld joint. Fatigue behavior and fatigue life test is minor's law and fracture analysis and nowaday, finite element method is used to many times. By considering the welding defect in the above, structural analysis is conducted to evaluate butt weld joint influence due to welding defect on the safety of steel bridges. The results indicate that, due to the insufficient welding penetration, the stress obtained in the analysis is over the allowable fatigue stress level, and its influence on safety of the bridges is significant

Anatomic abnormalities of teeth development include the presence of a single maxillary central incisor at midline instead of two central incisors. The incidence of cases with a single maxillary central incisor is approximately 1 in every 50,000 live births. single median maxillary central incisor(SMMCI) may be a integral manifestation of anyone of a number of syndromes. It has been reported an association with several midline disorders which have varied in severity. A SMMCI has also been reported as an isolated finding. But in some cases, it has been considered as an incomplete expression of autosomal dominant holoprosencephaly. So any patient who appears for treatment with a SMMCI should be referred for a detailed medical examination to exclude other associated systemic abnormalities and for mutation analysis to facilitate correct diagnosis and the provision of appropriate genetic counseling. Early orthodontic treatment is needed to minimalize emotional trauma of child. This case report was about three patients with a SMMCI as isolated finding. The purpose of these case reports was to present cases of single maxillary central incisor not associated with other disorders. Single Median Maxillary Central Incisor(SMMCI)는 상악 중절치 형성부전으로 하나의 상악 중절치가 정중앙에 위치하는 치아 발달의 해부학적 이상을 의미한다. 50,000명 중에 1명 꼴로 발생할 정도로 아주 드물며 각종 증후군 및 정중선 이형성을 보이는 발달장애와 연관되어 나타나는 것으로 보고되고 있다. SMMCI는 다른 이상과 연계되지 않고 독립적으로 나타날 수도 있으나 상염색체 우성유전인 전전뇌증(holoprosencephaly)의 경미한 발현일 가능성이 있으므로 유전자 상담이 필요하다. 또 특징적인 안모 및 구강 상태를 보이므로 환아의 바람직한 신체적,정서적 발달을 위해 조기에 교정적 접근이 필요하다. 본 증례는 다른 이상 소견을 보이지 않는 세 명의 SMMCI 환아의 증례를 보고하는 바 이다.

In this study, Taguchi method, one of the design tools of experiments, was applied to optimize casting process parameters of the high silicon corrosion-resistant iron. Three casting process parameters such as melting temperature, rare earth metal (mischmetal) addition, and pouring temperature were chosen. Using SN (signal-to-noise) ratio calculated from ultimate tensile strength of each experimental casting run, the relationship between the casting parameters and mechanical properties was statistically evaluated. The casting condition of a melting temperature of 1,650℃, 0.2% rare earth metal addition, and a pouring temperature of 1,350℃ led to an excellent ultimate tensile strength above 11 kgf/mm², which is beyond the industrial criterion. The effects of the casting parameters on mechanical properties and corrosion resistance were further confirmed by combined analysis of fractography, hydrogen content determination, microscopic test, and acid resistance test.

유치 맹출전에 치조융기에 가해진 외상은 유치의 맹출 지연 및 형태이상,치배의 변위 등을 일으킬 수 있으며 심한 경우 구개의 흠 형성,절치의 결함 및 후천성 구개열 등을 야기할 수 있다. 본 증례는 치아가 맹출하기 전에 수차례의 기관 삽관을 시행한 병력이 있는 심한 저체중아에서 맹출지연,형태이상,법랑질 저형성,영구치 치배 등의 변위가 관찰되어 이를 보고하는 바이다. Delayed eruption and abnormal morphology of the primary incisors following intubation may be due to follicular displacement and localized trauma caused by the process of intubation. Result of such damage included palatal groove formation, defective incisors and acquired clefts. This clinical report presents effect of intubation on the primary dentition of premature low-birth-weight children prior to tooth eruption.

R.C. Slab System의 信賴性解析 및 設計規準

申鉉默,李相哲 成均館大學校 科學技術硏究所 1983 論文集 Vol.34 No.2

This study proposes a reliability based design criteria for the reinforced concrete slab system. Resistence and load factors corresponding to the target reliability index (β_0 = = 3.0) which is considered to be appropriate level of reliability are calculated by using the proposed methods. Because of the large variation in load-effect uncertainties, the magnitudes of the factors varied considerably depending on the design section being considered. The same set of load factors associated with different resistence factors for each different design bay of a slab system are adopted as a reliability based design criteria for the purpose of practical. design applications.

The total number of woody plants species appeared in the investgated area were 31 families 45 genus 79 species including 8 varieties and 1 fomular. Importance values(Ⅳ) of the tree species of forest area in Seoul, Quercus mongolica showed the highest Ⅳ and Robinia pseudoacacia, Prunus sargetii, Pinus densiflora, Quercus acutissima, Sorbus alniflora were dominant species at conopy layer. Importance values of major tree species in relation to topographic feature, Quercus mongolica was higher in northern aspect than in southern aspect and at valley topography was higher than at ridge topography while Robinia pseudoacacia showed higher in southern aspect than in northern aspect and at ridge topography was higher than at valley topography, and Pinus densiflora showed high Ⅳ at ridge topography of southern aspect. As the result of COA Ordination analysis for fifty three plots belong to twenty five survey site of forest area in Seoul were divided into four vegetation communities which were Quercus mongolica-Prunus sargetii community, Quercus mongolica community, Robinia pseudoacacia community, Quercus variabilis community. Shanon’s species diversity indicies range of each community was 1.3822∼1.1189, and Quercus monglica community showed the highest species diversity and Quercus monglica - Prunus sargetii community showd the lowest.
