The purpose of this study is to analyze the problems of land and sea breeze model experiment that has presented in $5^{th}$ grade curriculum in chapter "Weather and our lives" and makes better model simulation so that learners can have better and more effective way to study it. To survey the opinions from dedicated teachers about land and sea breeze model experiment, we produced the survey through interview with science exclusive teacher from M elementary school. An elementary science education expert, 3 men of science EdD modified and complemented survey and started Delphi survey to 12 science teachers who have career teaching more than 3 years. The problems found in this survey were 'one heat bulb, short heating time, small temperature difference of water and sand, lack of class time, empty space between sand and water, back of transparent boxes, little amount of scent and the location of the it' etc. But the most of all, it is hard to see the successful result of the experiment. Based on these kinds of investigations, and lots of trial and error, redesigned the new model experiment that has the most similarity to the real one and high probability of success. According to this, it was able to see the smoke forms horizontal movement along the sand and the smoke goes in one circulation cycle. through this experiment, we made a conclusion that although those scientific experiments in textbook were developed through lots of considerations of expert, to consider the aspect of consumer, it needs to reach the educational agreement about simulation experiment so that It can lead to successful experiment and high quality education.

This thesis compares the duration aspect of Daegu tongue with that of standard Korean. In the former study on the rhythm of standard Korean, one of the purposes of the study was to compare it with dialects. This thesis is the first attempt In do that. For this purpose, this thesis proceeds as follows. After Introduction, Chapter 2 surveys the former study, Chapter 3 deals with the materials, method and results of the experiment. Chapter 4 analyzes and interprets the results of the experiment. In Conclusion, the most prominent fact is that the results of the experiment fall short of Daegu tongue speakers' expectations. Daegu tongue is generally considered as ' tone language. ' And as Daegu tongue speakers sensitively recognize pitch, they think that they quitckly say the syllables between the pitch stressed syllables, whereas standard Korean speakers say those syllables relatively slowly. But in this experiment, which deals with only duration ignoring pitch, their assumption is proved to be false.
