This study was to examine the effects of teacher's encouraging language on elementary student's adjustment to school life. To achieve this purpose, teacher's encouraging language were drawn from Adlerian literatures and ten principles of encouragement were established as the following: recognizing the student's values and potentials, putting an emphasis on student's positive sides, helping the student realize his or her own strength, tolerating student's mistakes, using perceptual alternatives, practicing self-encouragement, accepting and supporting opponents, stimulating internal motivations, and emphasizing social usefulness. Subjects were 34 1st graders at J elementary school in CheonNam. 17 subjects were assigned to experiment group and 17 subjects were assigned to control group. Teacher's encouraging language were applied to experiment group and teacher's usual languages were provided to control group for ten weeks. The quantitative data were collected through Elementary school adjustment behavior rating scale(Oh, 2009) and were analysed via ANCOVA. The qualitative data were collected through observations and products of the subjects and were analysed via qualitative methods. The results showed that teacher's encouraging language had a positive effect on the student's adjustment to school life.

The purpose of this study was to determine whether changes of position might effect the convergence pulmonary function of the 20s men of mild intellectual disabilities with obesity. Ten subjects of mild intellectual disabilities with obesity(fat group) and ten contrary subjects without obesity(control group) were participated in the experiment. Subjects were assessed for their pulmonary function by using Fit mate according to the position changes(supine position, 45 lean sitting position, 90 sitting position). One-way repeated ANOVA analyzed each region data of pulmonary function of both the fat group and the control group according to their position changes. The result of the experiment showed that the 20s men of mild intellectual disabilities with obesity have lower pulmonary function than the contrary subjects in the each given posture. In comparison with three experimental positions, supine position was the lowest in the pulmonary function. This study showed the 20s men of mild intellectual disabilities with obesity have lower function of pulmonary volume than the control group, and thus, it suggests that the pulmonary functional data of 20s men of mild intellectual disabilities with obesity in this experiment can be used as a basic respiratory one for the various exercise programs in the area of the physical activities.

Recently there are increasing concerns on quality improvement activities related to difficult economic situations, more competitive environment, health professional's emphasis on quality, and customer's needs in health care. The purpose of this study was to identify educational needs in the quality improvement for staff nurses. Study setting was an acute care hospital having more than 1000 bed in Seoul, Korea. The subjects were 40 staff nurses who participated in the first Quality Assurance(QA) inservice education. Data were collected by self-administered questionnaire which consisted of four parts : QA knowledge and attitude(ten items, by five Likert scale), contents of QA education(ten items, by setting the priority), evaluation of the program(structure, time allocation, place, educational method), and general characteristics of respondents (age, duration to work for hospitals etc.) The response rate was 85%(34/40), Most had positive perspective and attitude about QI/QA activities, but 9% had negative impression and knowledge about this activities. Also they'd like to know the plan of hospital-level QI/QA activities, QI/QA current practice, general hospital system, the role of QA specialist and so on. Consequently, for building the quality improvement activities that is customer-focused, coordinated, outcome-oriented, resource-efficient, collaborative in Korea, at first the education about philosophy, theory, and implementation process of QI/QA should be conducted, and then that on QI/QA terminology, quality indicators development, the analysis and presentation of quality-related data and so forth be followed.

Finding promising wind farm sites in islands of Korea is performed in this study. Total ten islands that have been measuring wind speed and direction using automatic weather stations for at least ten years were subjects of this study. Conditions for finding suitable wind farm sites including wind resource and various exclusion factors were applied and two islands that were found not to be suitable for wind farms were excluded. Micositing of a single wind turbine for the remaining eight islands was performed to estimate the annual energy production and the capacity factor.. Based on the simulation results, the wind farm sites selected within the eight islands were found to be suitable for wind power. The capacity factors were varied between 22.3% and 33.0% for a 100 kW wind turbine having a hub height of 30 m.

Western singers voice have been studied in music science since the early 20th century. However, Korean traditional singers voice have not yet been studied scientifically. This study is to find the physiological and acoustic characteristics of Pansori singers voices. Western singers participated for comparative purposes. Ten western singers and ten Pansori singers participated in this study. The subjects spoke and sung seven simple vowels /a, e, i, o, u, c, w/. An analysis of Glottal image was done by Scope View and acoustic characteristics of speech and singing voice were analyzed by CSL. The results are as follows: (1) Glottal gestures of Pansori singers showed asymmetric vocal folds. (2) Singing vowel formants of Pansori singers showed breathiness based on Spectrogram. (3) Music formant of western singers appeared in around 3kHz area, however, Pansori singers formant appeared in low frequency area. Modulation of vibrato showed 6 frequency per sec in case of western singers. Pansori singers showed no deep modulation of vibrato on spectrogram.

The first purpose of this study was to compare kinematic variables during spinning motion with or without upper extremity and identify the most effective spinning method. The second purpose of this study was to compare functional difference between novice and elite dancers with the term of training. Ten experienced female dancers and ten novices were recruited as subjects for this study. Elite group was asked to perform turn motion with three types of upper extremity. Novice group has taken training of spotting technique for five weeks. Four Falcon HiRES cameras were used to analyze kinematic variables including head angular velocity and CG displacement during spinning. These data were sampled before training, after 3-week, and 5-week of training. Eight different events in two consecutive turns were defined for statistical comparison. One-way ANOVA was performed to compare among the kinematics of turning motion with three types of upper extremity. Independent t-test also used to compare kinematics between elite and novice at three different length of training. As results, spinning with both arm increased angular velocity and stability compared to the turning motion with one arm or with arm strapped and found out that the turn with both arm was the most effective way of spin. Also, for novice dancers, three weeks of training were needed to complete spinning motion.

The purpose of this study was to compare kinematic variables and stiffnesses of ankle joints between normal person and transfemoral amputee gait in order to develop or fit prosthetic leg. Twenty subjects (ten normal persons and ten transfemoral amputees) participated in this experiment, and walked three trials at a self-selected pace. The gait motions were captured with Vicon system and variables were calculated with Visual-3D. The velocity, stride length, stride width, cycle time, double limb support time and right swing time of gaits were statistically significant. Because coefficients of variability of normal persons on velocity, double limb support time and swing time were greater than transfemoral amputees, normal persons controlled these gait variables effectively. The stiffnesses of ankle joints were not statistically significant, but patterns of stiffnesses of ankle joints during three rockers were absolutely different. The negative correlations between stiffnesses of ankle joints and cycle time and swing time were presented. These differences suggest that developing and fitting prosthetic leg were demanded. Further studies should develop fitting program and simulator of prosthetic leg.

This study was carried out to determine the effect of $-6^{\circ}$ head-down bedrest on the cardiovascular and hormonal responses to orthostasis and to evaluate the mechanism of orthostatic intolerance. Ten healthy young men were changed the body position from $-6^{\circ}$ head-down or supine bedrest for 2 hr to $70^{\circ}$ head-up tilt for 20 min. During the bedrest, there were no differences in hemodynamic and hormonal changes between the head-down and the supine positions. However, the tendency of decreased end-diastolic volume and increased cardiac contractility during the later period of 2 hr showed that the cardiovascular adaptation could be accelerated within a relatively short period in the head-down bedrest. During the head-up tilt, presyncopal signs were developed in five subjects of the supine bedrest, and one of the same subjects of the head-down bedrest. In the tolerant subjects, the increase in cardiac contractility and plasma epinephrine level during the bend-up tilt was greater following the head-down bedrest than that following the supine bedrest to compensate for reduced venous return. The intolerant subjects showed the greater decrease in end-diastolic and stroke volume, and the greater increase in heart rate during the head-up tilt than the tolerant subjects. Cardiac contractility and plasma epinephrine level were remarkably increased. However, arterial pressure was not maintained at the level for the appropriate compensation of the reduced venous return. It seems that the tolerance to orthostasis is more effective after the short-term head-down bedrest than after the supine bedrest, and the secretion of epinephrine induces the higher cardiac performance as a compensatory mechanism fur the reduced venous return during the orthostasis following the head-down bedrest than the supine bedrest.

The purpose of this study was to evaluate the general characteristics, complications and level of social adaptation of spinal cord injured patients. The subjects were one hundred forty five members who were inpatients or outpatients from October 1, 2004 to April 30, 2005 in general hospitals and municipal welfare centers for the handicapped located in the metropolitan city of Gwangju. The following results were obtained using Modified Barthel Index (MBI). 1) Gender distribution was 77.9% male and 22.1% female. The mean age at the time of injury was 35.4 and the mean age during the study was 44.2. 2) The degree of paralysis among the subjects was as follows: 49.0% had complete paralysis and 51.0% suffered incomplete paralysis. The most frequently injured lesion among the subjects was cervical (49.0%), followed by thoracic (35.9%), and lumbar (15.2%). 3) The mean MBI score was 63.5. There was statistically significant difference in the MBI score in the relation between complete and incomplete paralysis, the relation between cervical, thoracic, and lumbar injury, and the relation between a recovery period of less than three years and more than three years according to the characteristics of injury (p<.05). 4) There was statistically significant difference in the MBI score of subjects who had complications concerning spasticity, deformity, urinary tract infection, and sexual dysfunction (p<.05). 5) The most serious emotional pain after spinal cord injury resulted from economic issues, which affected 35.2% of the subjects. The group having a shorter recovery period after spinal cord injury complained of psychological matters, the group having a longer recovery period complained about the surrounding environment (lack of convenient facilities), suggesting statistically significant difference (p<.05). 6) The most common activities of the group with injuries more than ten years old included meeting schoolmates and working, while most common activities of the group with injuries less than three years old included attending religious functions and miscellaneous others (watching TV, spending time with family), suggesting statistically significant difference (p<.05).
