高等學校數學에 位相의 導入內容에 關한 硏究 : 圖形의 位相的性質을 中心으로
蘇元燮 공주대학교 사범대학 과학교육연구소 1978 과학교육연구 Vol.10 No.1
According to the progress of mathematical education, the middle school's mathematics in our country has dealt with the topological property of figures. But. the high school's mathematics has not dealt with this topological property of figures. I conceive that the high school's mathematical education will treat this contents in the future. This treatise had treted induced contents in case of inducing the topological property of figures to the high school's mathematical education in the future. The main induced contents have composed of simplex, complex and manifold and so on by the elementary concept of Homology theory for the understanding of the high school's students.

The Correlogram in Fourier analysis is often applied to method of the least squares, stochastic process and infomation theory. It, however, gives many troublesome difficulties in its practical application. In order to remove the difficulties just mentioned above some new operators of integral have been induced in this paper, and with the help of them the correlations between the operators and correlogram have also been induced. It is attempted to make the application of correlogram easier than till now.

In this paper, some properties and applications of Fourier-Stieltzes transforms are studied. In theorems 1 and 2, the properties of Fourier transforms are proved. In theorems 3 and 4, the properties of Fourier-Stieltzes transforms are proved. And finally in theorem 5 the application of Fourier-Stieltzes transforms to the probability theory is studied.

圖形의 實驗的 方法에 依한 指導 : 中學校 圖形의 觀察을 中心으로 On the basis of observation of figures in junior high schools
蘇元燮 공주대학교 사범대학 과학교육연구소 1981 과학교육연구 Vol.13 No.1
The main objects of Mathematics education are to have students understand mathematical systems through grasping the basic concepts, prnciples and rules of mathematics and cultivate their attitude and ability to think logioally. Especially, in teaching of figures, it is important to made students understand the composition and characteristics of basic figures through intuitive investigation, and thus cultivate the basic ability of figure investigation. It is not supposed to be easy to be easy to let the students understand topological properties and topological transformation in teaching of figures. Now the point is how teaching can be performed for the secondary school students to understand the topological properties and transformation of figures easily. In this thesis, an attempt is made to perform teaching in topological properties and transformation of figures through experimental methods. Figures are drawn on the thin rubber plates and the students are led to understand the properties of figures intuitively by transforming the plates. Conclusively, this method mentioned in this thesis is supposed to be better than any other method, for example, the one with over head projects.

난청 성질과 청력손실 정도에 따른 어음이해 및 음소 오류
소원섭,김혜련,서혜경,허승덕,목소라 한국청각언어장애교육학회 2013 한국청각·언어장애교육연구 Vol.4 No.1
This study will confirm the effect of phoneme score (PS) and the characteristics of the phoneme error (PE) depending on type and degree of HL in order to obtain basic informations of audiological rehabilitations. Post-lingual acquired hearing impaired-person were participated. SDS, PS and PE were analysed depending on type-, dgree of hearing loss, retrospectively. Regarding the results of the analysis, SDS was observed 88.0±10.1 in conductive HL, 71.7±23.7 in sensorineural HL, 84.8±14.3% in mixed HL, 83.1±8.9 in mild HL, 78.1±14.4in moderate HL, 77.5±18.8 in moderate-severe HL, 45.3±40.5% in severe HL. SDS was significantly effected depend on type of HL and on degree of HL. PS was observed 95.4±4.2 in conductive HL, 83.6±20.0, in sensorineural HL, 91.7±8.6% in mixed HL, 92.3±4.6 in mild HL, 89.1±8.8 in moderate HL, 88.2±11.2 in moderate-severe HL, 59.7±38.1% in severe HL. PS was significantly effected depend on type of HL and on degree of HL. 본 연구는 청각언어재활 계획 수립을 위한 기초 자료를 획득하기 위하여 난청 성질과 청력손실 정도가 음소 성적에 미치는 영향 및 음소 오류 특성을 확인하고자 한다. 연구 대상은 언어 습득 후 난청이 발생한 성인들로 하였다. 난청 성질과 청력손실 정도에 따른 어음이해도, 음소 성적, 음소 오류 유형 등을 후향적으로 분석하였다. 본 연구의 결과, 난청 성질에 따른 어음이해도는 전음성, 감각신경성, 혼합성 난청의 순서로 88.0±10.1, 71.7±23.7, 84.8±14.3%, 난청 정도에 따라서는 경도, 중등도, 중등 고도, 고도이상의 순서로 83.1±8.9, 78.1±14.4, 77.5±18.8, 45.3±40.5% 등으로 각각 관찰되어 난청 성질과 정도에 따른 어음이해도는 유의한 차이를 보였다(p= .005). 난청 성질에 따른 음소 성적은 전음성, 감각신경성, 혼합성 난청의 순서로 95.4±4.2, 83.6±20.0, 91.7±8.6%, 청력손실 정도에 따라서는 경도, 중등도, 중등 고도, 고도이상의 순서로 92.3±4.6, 89.1±8.8, 88.2±11.2, 59.7±38.1% 등으로 각각 관찰되어 난청 성질과 정도에 따른 음소 성적은 유의한 차이를 보였다(p= .001).

이 연구는 이학적·청각학적 정상 소견을 가진 성인들의 다중주파수 고막운동도(multi-frequency tympanogram, MFT)와 다중성분 고막운동도(multi-component tympanogram, MCT)의 특성을 알아보고자 하였다. 연구 참여자는 D대학교 재학 중인 19명(M:F=9:10, 만 19∼23세)으로 하였다. MCT는 각 성분(admittance; Y, susceptance; B, conductance; G)별 정점의 수를 확인하였고, MFT는 200 ㎐부터 2 ㎑ 순음에 대한 고막 긴장 및 이완상태에서 전도율을 통해 공명주파수와 ΔB, Δ∅를 각각 구하였다. MCT는 668 ㎐ 자극에 대해 47.4 %가 1Y1B1G를, 52.6 %가1Y3B1G를 보였고, MFT의 공명주파수는 829~1,213(1,021±192) ㎐, ΔB와 Δ∅의 평균은 각각 –0.18, -19.3으로 관 찰되었다. This study will be to confirm the characteristic of Multi-component tympanogram(MCT) and Multi-frequency tympanogram(MFT) of adults who have physical and audiological normal findings. Participants were 19 students(M:F = 9:10) who are attending D-university. MCT checked the number of peaks per each component(admittance; Y, susceptance; B, conductance; G) and MFT got the resonance frequency through the conductivity rate of tympanic membrane's tense and relaxation state, and ΔB, Δ∅ respectively. 47.4% of MCT showed 1Y1B1G about 668 ㎐ stimulus and 52.6% of that showed 1Y3B1G. Resonance frequency of MFT was 829~1,213(1,021±192) ㎐, and the average of ΔB and Δ∅ was observed -0.18, -19.3 respectively.

Normed space is not always complete on the given norm, but complete normed space is important part of mathematics. In this note we prove that the necessary and sufficient conditions for the completness of given normed space. We shall, infact, prove the following result. Normed space N is complete if and only if ?? is strongly convergent when χ₁, χ₂,.....,??,.....?? and ??<∞
