The purpose of this paper is to establish standard for selecting musical materials for teaching English pronunciation in elementary school. For this purpose, 110 songs of wee sings and the curricula of English and Music of elementary school are analyzed, and the results became the basis of establishing standards. Four standards are established and each standard divided into several steps according to the degree of complexity. And the degree of complexity of two songs are figured out to know the possibility of application.

The purpose of this study looks for the directions to improve the performance evaluation of cook by examining the perceptions for performance of cook by supervisors in hotel restaurant. In order for this purpose, this study focuss on two areas: (1) the significant differences of each hotel type on the perceptions of each performance evaluation item, (2) the significant differences of each kitchen type on the perceptions of each performance evaluation item in terms of two different types of hotel. To examine (1) and (2), this study uses Student t test and anova analysis. The findings from this study have both theoretical and practical implications. Implications of these findings are discussed.

The purpose of this study is to develop the computer software for the nonlinear analysis of R/C frame structure under static loads. For this purpose, strain-rate dependant material model and physical element model considering both flexural and shear deformation are adopted and they are connected with 'TWO-D'which is commerical software for elastic structural analysis. The analytical results using the developed software are compared to the experiment results and they are generally satisfactory.

The purpose of this paper is to use hydraulic sources optimally on the hydro-thermal power coordination in power system of Korea by means of Multiple Dynamic Programming. Four principal hydraulic power plans of Korea; Whachon, Chunchon, Uiam and Chong-pyong which are located on Han river side are treated in this research. For the illustrative purpose, a case study was made on the year round monthy optimal water control under the given load distribution and constraints.

The purpose of this research Is to derive the principal design parameters governing the dynamic characteristics of the high response flow control servo valve. For this purpose, a numerical modeling of the servo valve system and a parameter sensitivity analysis to a frequency response characteristics was peformed. As a result of these analysis, a basis for improvement of a dynamic characteristics of servo valve was arranged.

The appropriate sample size calculation in dental research is important to achieve the study purpose at the first step in study design. However, it cannot be easy to calculate sample size using standard formulas, because the several factors must be considered for calculation. This study introduced the graphic method for sample size calculation, which is called nomogram. The purpose of this study is to show the effectiveness of the nomogram using examples, expecting the researchers can easily use nomogram for sample size determination.

This study is to suggest the perspectives of family resource management education in social education. From this purpose, necessity and position of FRM education in social education are discussed. And the perspectives about FRM education are presented from delphi research to experts. This perspectives contain the purpose, sphere, relation to existing programs, education for housewife, future tasks. Finally, several names of education program are illustrated in two dimension, which is divided into consciousness-raising and technique-learning in content and personal and family in object.
