AlN single crystals were grown by the PT (Physical vapor transport) method with position-changable induction coil. And the graphite crucible dimensioned ${\Phi}90{\times}H120$ was used on processing. The temperature was $1950{\sim}2050^{\circ}C$ and ambient pressure was 150~1 Torr. And the hot-zone was changed according to times on growing for result comparison. When hot-zone by coil is located below far enough (> 40 mm) from AlN crystal concentration position, the as-grown crystals physical size is better ($300{\mu}m/hr$) than another condition, but the condition-reproducibility was very poor. However the closer the distance between hot-zone and AlN growing posion, the smaller the size of as-grown crystal and the rarer the generation of the crystal nuclear, but the crystal growing condition is stable for quality. The best condition for both growth rate and quality is gained when the starting position of hot-zone coil is about 20 mm distance from growing position. For the best growth condition, the position of hot-zone is very sensitive factor and the further more the condition of speed of coil shift also must control.

The purpose of this study was to examine the working condition of physical therapists and the degree of job satisfaction. This study also was to identify the causes of job stress: to examine job stress and job satisfaction; and to find factors that affect job satisfaction for physical therapists in Korea. A self-administered questionnaire survey was conducted from February 17 to March 15 in 2003. Survey data was obtained from 255 therapists registered in Korean Physical-Therapists Association. Results were as follows: 1. The degree of job satisfaction was moderate. 2. The degree of stress with their work was a little high. 3. Duty itself is one of the main factors of job stress of physical therapists. Working atmosphere and the relationships with job colleagues turned to be closely related to the degree of satisfaction. 4. The longer their total term of service was and the older they are, the greater the satisfaction with work was. In conclusion, the physical therapists can be encouraged to do their work more energetically and voluntarily. At the same time, the feeling of mission can also grow by shortening of working hours, reducing the quantity of work, and offering more salary. It is also to recommend an effective performance of duty and the development of their medical service to be introduced.

The objective of this study was to investigate the effects of starvation periods with aerobic or non-aerobic conditions on the organic removal efficiencies and physical characteristics of activated sludge for treating saline and non-saline wastewater. During the experiment, MLSS, MLVSS, sludge volume index (SVI), floc size and fractal dimension, $COD_{Mn}$ removal efficiencies were monitored. The reductions of MLSS, MLVSS and SVI with maintaining the sludge under a non-aerobic condition during starvation periods were smaller than those under a aerobic condition. Floc size, fractal dimension and $COD_{Mn}$ removal efficiencies were less decreased under non-aerobic condition than under aerobic condition. And SVI were strongly correlated with floc size and fractal dimension. Consequently, the result showed that maintaining the activated sludge under non-aerobic starvation conditions was better strategy than that under aerobic starvation conditions as it adapted and resisted to starvation.

Purpose: This study aimed to examine the relationship between pre and post operative sexual condition, differences in sexual attitude through post operational periods, and the relationship between sexual attitude and satisfaction. Method: Data was collected with questionares from 119 women registered in the gynecology department of a general hospital in Seoul who had undergone a hysterectomy. Result: There was a significant difference between the condition of pre and post operation coital frequency, sexual satisfaction, and spouse's attitude toward the extraction of the partner's uterus. There was a significant difference between their views of the operation. Twelve months after the operation sexual attitude of sexual aspects changed, but not in physical and psychological aspects. There was a significant difference between sexual attitude and satisfaction on sexual, psychological aspects, but not physical aspects. Conclusion: The findings suggest that a preliminary sexual condition be identified before surgery, scheduling the operation after helping a spouse gain a positive attitude about the hysterectomy, and couples in their 50's and older get counselling. Increased sexual satisfaction will develop with a belief in positive changes of sexual aspects, but a rapid change should not be expected.

As the basic study to investigate the mechanism of improvement in the dyeing fastness of natural dyes on silk fabrics the optical behavior of tannin solution, the optimal condition of tannin treatment and the changes of the physical structure of silk fabrics were studied in the treatment of tannin. Results obtained were as follows ; 1.The K/S values of tannin-treated silk fabrics were not changed by tannin content on silk fabrics but yellowing of tannin in treatment condition. 2. As the concentration of tannin was increased in its treating condition, the tannin content and K/S vague of tannin-treated silk fabrics were increased. 3. Because tannin gave rise to yellowing by hydrolysis and oxidation at high temperature, the higher tannin-treating temperature was, the lower the tannin content and K/S values of silk fabrics 4. The tannin content of silk fabric was higher in acidic treating condition and the highest K/S value was showed at pH 5. 5. As the tannin content of silk fabric was increased, the value of ζ -potential of it became negative. 6. As the tannin content of silk fabric was increased, the crystallinity and crystallite size of it were decreased. This meant that the fraction of amorphous region in the fibers increased. And the degree of orientation of it was decreased with the tannin treatment.

Numbers fitting-curve equations have been proposed to predict soil-water retention curve (SWRC) whose parameters have no definitude physical meaning. And these methods with precondition of measuring SWRC data is time-consuming. A simplified directly method to estimate SWRC without parameters obtained by fitting-curve is proposed. Firstly, the total SWRC can be discretized into linear segments respectively. Every segment can be represented by linear formulation and every turning point can be determined by the pore-size distribution (PSD) of Mercury Intrusion Porosimetry (MIP) tests. The pore diameters governing the air-entry condition (AEC) and residual condition (RC) can be determined by the PSDs of MIP test. The PSD changes significantly during drying in SWR test, so the determination of AEC and RC should use the PSD under corresponding suction conditions. Every parameter in proposed equations can be determined directly by PSD without curve-fitting procedure and has definitude physical meaning. The proposed equations give a good estimation of both unimodal and bimodal SWRCs.

The purpose of this study was to determine the influence of muscle fatigue in elbow flexors on the sense of force reproduction. Fifteen healthy subjects were recruited for this study. Maximum voluntary force (MVF) of elbow flexor muscles was measured by a digital tensiometer. Force errors were measured to test accuracy of the sense of force reproduction in elbow flexors. The subject was required to flex the elbow joint, to maintain and concentrate on about 20% of the MVF target force under visual feedback for 3 seconds. After a 5 second period rest, the subject was asked to duplicate the target force actively. Muscle fatigue was evoked with isometric contraction of the elbow flexors. Isometric contraction was continued until a 50% drop in MVF. The difference, in kilogram between the target force and the reproduced force was calculated for measuring force error. Force errors were compared between the non-fatigued condition and the fatigued condition by the paired t-test. Force errors were significantly increased in the fatigued condition compare to non-fatigued condition. This result suggests that the sense of force reproduction can be disturbed by localized muscle fatigue.
