Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

Clenbuterol, a selective β_(2)-adrenergic receptor stimulant, has been introduced as a potent bronchodilator for patients with bronchial asthma, chronic bronchitis and pulmonary emphysema. For the purpose of developing a transdermal preparation for clenbuterol, we attempted to select an optimal solvent system and permeation enhancer among fatty acids and fatty alcohols which are known to accelerate the penetration of various drugs in permeation experiments using hairless mouse skin and Franz diffusion cell. Apparent partition coefficient of clenbuterol was increased as pH of buffer solution was increased and solubility of clenbuterol was increased as the percent of propylene glycol(PG) in buffer solution(pH10) was increased. Permeability of clenbuterol from different buffer(pH 10)/PG solvent mixtures was decreased as the percent of PG in pH 10 buffer solution was increased and among the various enhancers studied, lauryl alcohol was found to be the most effective enhancer, increasing the permeability of clenbuterol approximately 76-fold compared with control. Lauryl alcobol(0-2%) enhanced the permeability of clenbuterol concentration-dependently. In this study, the optimal solvent system for the penetration of clenbuterol was found to be 50/50 buffer(pH 10)/PG solvent mixture containing 2% lauryl alcohol.

Carbonized rice hull, perlite, and vermiculite were mixed and investigated for the probability of tobacco transplant production by means of plug and transfer float system. These seedling bed materials in condition of float system have gaseous phase ranged from 6% to 13% showing a proper growth of tobacco seedling. However compost media mixed with soil, sand, and compost in condition of float system led to the shortage of respiration in root system by very low proportion of gaseous phase skewing a wicked growth of seedling. Absorption of heat by floating water for the daytime increased rhizosphere temperature in condition of float system during the night and low temperature season resulting in better growth of tobacco seedling. Consequently transplant production of tobacco seedling by float system with mixed materials of carbonized rice hull, perlite, and vermiculite was thought to be desirable method for manufacturing production system of transplant considering the effective management of water, nutrients, and temperature of seedling bed materials.

EXPERIMENTS IN THE USE OF FREQUENCY TYPE LEARNING CONTROL FOR PRECISION ROBOT MANIPULATOR

유영순 安東大學校 工業技術硏究所 1998 공업기술연구논문집 Vol.5 No.1

The theory developed gives a unifying understanding of the stability boundary for convergence to zero tracking error, and of a stability condition obtained by using frequency response arguments. Experiments in the use of learning control for high precision tracking in robot manipulators are performed. These experiments demonstrate the effectiveness of learning control concepts for improving high speed tracking accuracy by a large margin, with minimal knowledge about the system dynamics, and doing so very quickly and easily. These experiments use a hierarchy of learning control laws, and study the ability of these laws to reduce errors in a large angle trajectory involving all seven joints of a redundant 7 degree-of-freedom Robotics Research commercial robot manipulator. In order to maximize the difficulty and nonlinearity of the problem, this trajectory reaches the maximum rated speed for several of the robot joints, and travels through much of the workspace. When using only the rather sophisticated built-in joint controllers on this robot, the tracking errors reached a maximum of roughly 9 degrees. Application of learning control laws for 5 or 10 repetitions of the trajectory resulted in a decrease in this tracking error by a factor of 100 to 1000, depending on which learning control law was employed.

The social functions of dancing can be summed up as follows. 1. As a Communicatory function, dance is used not only to represent human will and expression biologically but also to produce dormant Capability and achieve physical-emotional unity. 2. As a play function, dancing satisfies human sportive instinct with its vertigo and Mimicry factors. 3. As an exorcistic function, man uses dancing in Shaman rituals and so forth as a way of getting over the limitations of human faculty. 4. As a medical function, man resorted to exorcisms in order to cure diseases by way of a catharsis methed in primitive times. Nowadays insane Patients and physically disabled persons are applied to a dance therapy. The researcher hopes many futher studies will be made along the medical function of dancing, so that the importance of dancing can be appreciated to cure and prevent illness.
