The purpose of this study was to develop and apply a differentiated instruction-learning reflecting various characteristics and demands of the gifted underachievers, and thereby help to develop the study attitude and study achievement of the gifted underachievers. To achieve the purpose, a case study on five gifted underachievers who are in $6^{th}$ grade of elementary school was conducted. By collecting and analyzing a variety of data including standardized tests, interviews with teachers, students, and parents, and observation journals, this researcher examined the characteristics and demands of the gifted underachievers. For the development of the program, differentiated strategies were designed according to students' interest and concern, their multiple-intelligence, and their learning styles. As a result of the application of them, a program with a total of 20 sections was finally developed. The result of the application for the differentiated instruction-learning program revealed improvements in their academic achievements. In addition, it was found that their learning motives were improved. The program was also found to affect their self-concept and their attitude toward learning. The study showed that developing an education program for the gifted underachievers should begin from the analysis of each student's characteristics. Also, it was found that a differentiation strategy could become an alternative to apply various characteristics and demands of the gifted underachievers to the development of a program. The gifted underachievers' intellectual and definitive characteristics were changed even by the short-term mediation. Therefore, the new issue about educating the gifted is to provide a differentiated instruction-learning program fitting their characteristics and demands and help them exert their potential as best as they could.

The purpose of this study was to define the relationship between the leadership style of head nurses and the burnout level of nurses by taking into consideration the factors which influence the level of burnout and which show how burnout varies according to the leadership style of lead nurses. The subjects of the survey were 355 ward nurses and their 48 head nurses working in five university hospitals in Seoul. The nurses were surveyed by means of a questionnaire from Sept. 22 though Sept. 29, 1983. The Leadership Scale devised by Fleishman, and modified by Lee, and the Burnout Scale developed by Pines et al, and adapted to the Korean situation by Peek, were used as a basis of ;his survey This researcher subjected the questionnaire to a pre-test and to an internal reliability consistency test through item analysis. For the purpose of analysis of the data, the general characteristics were set at Mean and the general characteristics of head nurses in relation to the level of burnout of nurses was analysed by the Pearson Correlation Coefficient. The relation between head nurses' general characteristics 3nd leadership style, the relation between nurses' general characteristics and level of burnout and the level of burnout of nurses according to the different style of leadership of head nurses were analysed by ANOVA. A summary of the results of the study is as follows. 1. Hypothesis:“That the burnout level of the nurse will be different according to the leadership style of the head nurse”was supported. 2. Analysis of the relationship between the head nurse's general characteristics and the leadership style of the head nurse showed that the leadership style of the head nurse was not related to age and experience as head nurse. 3. Analysis of the relationship of nurses' burnout levels to general characteristics of nurses showed statistically significant differences in burnout levels according to working departments, expected working period and reasons for selecting nursing as a profession. Also, the burnout level of nurses was negatively related to the head nurse's age and experience as a head nurse.

Objective: This study was to provide a standard for the evaluation of The Korean version of Adolescent/Adult Sensory Profile(K-ASP) for University students and to investigate the difference of the subjective sense recognition regarding the characteristics of sensory processing. Method: The subjects consisted of 84 University students. A researcher examined subjective sense recognition and K-ASP for subjects. Visual Analog Scale used to evaluate subjective sense recognition and K-ASP was utilized to evaluate the characteristics of sensory processing. Results: 1. The average scores and standard deviation of K-ASP were $32.93{\pm}7.88$ for low registration group, $39.39{\pm}6.55$ for sensory seeking group, $38.94{\pm}9.13$ for sensory sensitivity group, and $34.24{\pm}7.85$ for sensory avoiding group. 2. The correlation between the total score on an each quadrant and the subjective sense recognition are -.27 for low registration group, .11 for sensory seeking group, .09 for sensory sensitivity group and .12 for sensory avoiding group. It showed the statistically significant correlation between the total score of low registration and the subjective sense recognition group(p<.05). 3. The average scores and standard deviation of the subjective sense recognition were $5.22{\pm}1.56$ for high threshold and $7.28{\pm}1.70$ for low threshold. The subjective sense recognition according to the characteristics of sensory processing showed the statistically significant difference. Conclusions: This study supports the theory that there is the difference of sensory recognition according to each individual and we found that people with difficulties of sensory processing acknowledge their characteristics of sensory processing well. Evaluation of sensory processing ability through interview or questionnaire supports the fact which it is reliable.

Modulus of elasticity, modulus of rigidity, damping ratio, and natural frequency of three varieties of boxthorn (Lycium chinense Mill) (Cheongyang #2, Cheongyang gugija, and Cheongyang native) branches were analyzed. Modulus of elasticity and modulus of elasticity and modulus of rigidity of the boxthorn branch was determined using standard formula after simple beam bending and torsion test, respectively, using an universal testing machine. Damping ratio and natural frequency of branches were determined using a system consisted of an accelerometer, a PC equipped with A/D converter, and a software for data analysis. Relationship between the elastic modulus and branch diameter in overall varieties and branch types showed a good correlation (r -0.81). There was, however, no correlation between torsional rigidity and branch diameter. The internal damping results were highly variable and the overall range of the damping ratio of the boxthorn branch was 0.014-0.087, which indicated that the branch was a lightly damped structure. The natural frequency of the boxthorn branch was in the range of 89-363 rad/s for the overall varieties and branch types. A good correlation (r 0.82) existed between the natural frequency and branch diameter in overall varieties and branch type.

Empirical mode decomposition (EMD) is applied to analyze time series characterized with nonlinearity and nonstationarity. This decomposition could be utilized to construct finite and small number intrinsic mode functions (IMF) that describe complicated time series, while admitting the Hilbert transformation properties. EMD has the capability of being adaptive, capture local characteristics, and applicable to nonlinear and nonstationary processes. Unlike discrete wavelet transform (DWT), IMF eliminates spurious harmonics and retains meaningful instantaneous frequencies. Examples based on data representing natural phenomena are given to demonstrate highlight the power of this method in contrast and comparison of other ones. A presentation of the energy-frequency-time distribution of these signals found to be more informative and intuitive when based on Hilbert transformation.
