조성미,정옥란,이상욱 한국음성과학회 2004 음성과학 Vol.11 No.4

This study attempted to provide a spectrum analysis for quantitative evaluation of singing voice quality of singing students rather than the presence or absence of the singer's formant. The regression analysis was used to analyse the relationship between ringing quality, SPR, and SPP of singing voice of college student subjects majoring in music. This study measured singing power ratio (SPR) in 41 singing students. Digital audio recordings were made in sung vowels for acoustic analyses. Each sample was judged by 1 experienced singing teacher and 4 voice pathologists on one semantic bipolar 7-point scales (ringing-dull). The results showed that the SPR and SPP had significant correlations with ringing Quality. The SPR had a significant relationship with ringing quality on singing voice in singing students. The SPR can be an important quantitative measurement for evaluating singing voice quality.

The purpose of the study was to observe the association between the main colors of school chidlren's drawings of dental treatment situation and their dental anxiety. The subjects of study were 688 school children from 2nd to 4th grade. Caries experience was investigated by oral examination. Questionnaire survey was done regarding children's attitude toward the dentist and dental treatment and their experience of pain and fear during the dental treatment. Colors with high frequency of use were green, blue, yellow, orange, pink, purple, gray, brown, yellow ochre, red, white and black in order. Boys used green and blue, and girls used yellow and orange, more than each other. As the grade increased, white, yellow, and blue increased and brown decreased. Colors with high dental anxiety level were black, brown, red, white, blus, orange, yellow and green, yellow ochre, gray, pink, and purple in order, and the upper four represented 10.5% of the subjects. Children with high decayed teeth rate had a tendency to use colors of high dental anxiety level. Black color had the most obvious association with the pain and fear of dental treatment.

The purpose of this study was to investigate the effect of a moderate warm-up on static and dynamic muscular strength. The subjects were 60 male and 60 female college students, ages 18 to 21, who were not athletically inclined. Repeated measurement design was used for this study. Each subject was tested following the two conditions that one was no warm-up and the other was a 5 minute moderate warm-up. Rest interval between warm-up and test was 5 to 8 minutes. The order of test was randomized. For the measurement of static muscular strength Back Lift Test was used, and for dynamic muscular one Vertical Jump Test was used. The results were as follows: 1. In back lift test following warm-up, male got 7.06%(9.27kg) of significant increment (p<0.001) while female got 4.06% (3.60kg) of that (0.1<p<0.2). 2. In vertical jump test, male got 8.33%(4.70cm) of significant increment (p<0.001) while female got 1.69%(2.57cm) of that(p<0.001). In conclusion, the warm-up demonstrated significant superioity of muscular performances over no warm-up, and was more helpful to male than to female in both static and dynamic muscular strength, and was more benefical to dynamic muscular strength than to static muscular one.

조성초 群山大學校 1984 論文集 Vol.9 No.-

The purpose of this study was to investigate the immediate after-effects of various weighted preperformances on the kinesthetic perception of college men. The subjects were 56 college men, aged 18 to 21, who were volunteers. In the 1st experiment, all of them were tested according to the repeated design. In the 2nd experiment, 24 of them were equally devided into 8 groups and tested according the 8 x 8 rotation design. Distance Perception Jump Test(DPJT) was used to measure the kinesthetic ability of the subjects. The preliminary tasks for the 1st experiment were 10 trials of DPJT without weight and 10 trials of DPJT with 20% of each subject's body weight (2 treatments). and those for the 2nd experiment were 1, 4, 7 and 10 trials of DPJT with 10% of body weight and the same trials of DPJT with 20% of body weight(8treatments). During the tasks the eyes were used. In due form every subject was tested just after each of the tasks. The results were as follows: 1. There was no significant difference between 10 trials of DPJT without weight and 10 trials of DPJT with 20% of body weight, and none of them did not affect the DPJT scores of the subjects. 2. There was also no significant difference among all the treatments which were made up of weights and trials. 3. When the post-test scores (after whole tasks in the 2nd experiment) were compared with the initial test scores (before tasks), errors of distance perception were significantly decreased.

The purpose of this study was to investigate the best hip angle for exerting the back strength lift, and to compare the new back lift test with the two traditional methods. The subjects for the 1st experiment were 104 college men, aged 18 to 21, who were volunteers, and for the 2nd experiment 36 of them were selected. In the 1st experiment, the subjects were equally divided into 8 groups, and according to the 8×8 rotation design each group's back lift was measured by the prescribed hip angle. In the 2nd experiment, three different back lift tests were compared one another according to the 3×3 rotation design. The results were as follows. 1. The best hip angle for exerting back strength lift was 160°, followed, in descending order, by 170°, 150°, 140°, 130°, 120°, 110°, and 100°. 2. By the new testing method with the hip angle 160°, about 5% (7kg) higher score was made at significance level p<0.01, compared with the two traditional testing methods, while there was no significant difference between the two traditional ones.

Sputter-texttured Mo 박막이 CoCrTa/Cr 자기기록매체의 자기적 성질에 미치는 영향

조성묵,남인탁 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.A

The effect of Mo underlayer on the magnetic properties of CoCrTa/Cr films deposited on glass substrates were investigated. The coercivity increased and the coercivity squareness decreased by introducing Mo underlayer. The coercivity increase was attributed to the increase of in-plane c-axis orientation and magnetic isolation of Co grains deposited on Cr/Mo underlayer. The decrease of coercivity squarenesses seemed to be caused by the increase of magnetic isolation. The increase of magnetic isolation of Co grains was attributed to the diffusion of Mo atoms into Brain boundaries of Co films and the physical isolation of Co grains. The coerciyity of CoCrTa/Cr/Mo showed maximum values at Mo thickness of 400Å. The appearance of the maximum coercivity at that thickness was attributed to the development of strong Co(10□ Θ) and Co(10□ 1) preferred orientation.

조종수,김종인,김사익,권상오 진주산업대학교 농업기술연구소 2000 農業技術硏究所報 Vol.13 No.-

The resistance against discoloration, value of crack and surface characteristics of coating films on seven domestic lumbers and those of four introduced tropical lumbers were investigated to evaluate the properties of coating films by the varnish of Dendropanax morbifera. The moisture contents of the investigated lumber species were not significantly different from each other. There was insignificant correlations between the hardness and moisture contents of each lumber treated by the varnish. There was no significant correlations between the thickness of coating film and the hardness, either. Although we investigated 11 lumber species, we found only three species as resistance lumber species against discoloration; Diospysos spp., Abies holophylla and Ulmus davidiana. The resistance against discoloration coated by the varnish of Dendropanax morbifera was the largest on the lumbers of Diospysos spp.(Δ2.68) followed by Abies holophylla(Δ3.26) and Ulmus davidiana(Δ3.30). The crack of coaing films was the largest on Zelkova serrata followed by Juglans sinensis, Cercidiphum iaponicum, Tectona grands, Ulmus davidiana, Guibourtia tessmannii, Diospysos spp., and Dalbergia latifolia. However, there was no crack of coating films on the lumbers of Juniperus rigida, Prunus serrulata var. spontanea and Abies holophylla. The crack of coating film showed positive correlations with the thickness of coating film and hardness. The surface characteristics of the coating films evaluated on the basis of Ra values indicated the lumbers of Ulmus davidiana(0.14㎛), Juniperus rigida(0.15㎛), Guibourtia tessmannii(0.19㎛), Dalvergia latifolia(0.20㎛) and Diospysos spp.(0.20㎛), Cercidiphum japonicum(0.24㎛) as good species while there was insignificant differences between softwoods and hardwoods. Tectona grands, Prunus serrulata var. spontanea and Abies holophylla showed rough surface with 1.53∼2.63㎛ of Ra values. The four kinds of rough indices(Ra, Rz, Rmax and Rq) showed very low correlations with moisture contents with the correlation coefficients in the range of 0.30∼0.33. The Ra and Rmax also showed little relationships with hardness(r=0.51 and 0.48, respectively).
