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.

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.

Theophylline kinetics and metabolism following single intravenous infusion of theophylline dose (6mg/kg) were examined in 8 young non-smoking adults. Study design stressed stringent control of several external factors known to influence theophylline metabolism. The concentrations of theophylline were analyzed over a 24-hr period in plasma. Theophylline and its major metabolites were measured over a 96-h period in urine after the given dose. A 2-compartment model was required to describe the theophylline plasma concentration time course in all 8 subjects. The results are as follows. 1. Theophylline is quickly transferred from plasma to tissue with high rates of intercompartmental clearance (mean ±S.D; 1.04 ± 0.53 L/min). Steady-state volume of distribution of theophylline showed little intersubject variability with average of 0.42 ± 0.02 L/kg. 2. The elimination half-life of theophylline varied greatly among subjects and ranged from 4.56 to 11. 11 hours, Similarly, the non-renal clearance also showed wide intersubject variation (coeffient of variation; 35%). 3. The unbound fraction of theophylline was 62.6 ± 4.1% at the plasma concentration around 10 ㎍/ml. 4. About 82% of theophylline administered was recovered until 96-hr after dose as unchanged form or major metabolites. A 17.55% of theophylline was excreted in urine as unchanged form. Molar fraction of theophylline metabolites 1.3-dimethyl uric acid, 3-methylxanthine and 1-methyl uric acid excreted in urine were 35.14%, 11.62% and 17.64%, respectively. From the above results, It is suggested that great variation of theophylline elimination half-life seems to be mainly due to wide intersubject variation of non-renal clearance of theophylline. Importance of including an assessment of plasma protein binding in studies of theophylline disposition would be emphasized, because theophylline metabolism showed a restrictive pattern. Incomplete recovery of theophylline from the administered dose imply the possbility of exsistence of additional minor pathways in theophylline disposition, which could not be identified in the study.

This paper presents a method to design pseudo decentralized load frequency control(LFC) based on digital controllers which improves dynamic responses in multi-area power systems by incorporating computational time delay. Assuming that the amplitude of the load fluctuation is small and invariant, behavior of the power system in expressed by a set of linear differential equation, with constant coefficients. First, in order to synthesize a sampled date controller, the system is digitalized at appropriate sampling period by using numerical approximation method. Next, the centralized control gains incorporating time delay are determined based on the optimal theory. In order to damp a constant disturbance, we make use to digital servo system having one controller delay. From the point of view of application to LFC problem, the area control error (ACE) is chosen as output variables of servo system.

The purpose of this thesis is, through the positive study, to clarify the effects of mental practice on performance and learning to the closed skill of children, what differences there are between mental practice and physical practice, whether or not the mental practice is effective in case it is performed simultaneously with physical practice, and when the effects of mental practice come out. The subjects are all right-handed elementary school students who are in the fifth grade and divided into four groups through four-step preliminary test. The subjects throw balls toward the five-meter apart target whose center is one meter high from the ground with their feet stuck on the ground. The points are treated 'ANOVA with repeated measured'-practice conditions(four variables) times practice periods(four variables)- making use of PC-SAS. If meaningful differences are found, they are put under the afterward identification - 'Turkey's HSD.' The material analysis brought the following conclusions. First, the skill performance effects are not found according to the practice conditions, but the practice performance effects are found according to the practice period. Second, the learning effects are not found according to the practice conditions, but the skill learning effects are found according to the practice period. Third, in the latter part of the practice period are the learning effects of the mental practice found.
