An experiment of the growth of single crystals of SnSe_2 has been carried out using a direct vapour phase transport method. Tin diselenide has the hexagonal structure and the lattice constants a_0 and c_0 were measured to be a_0 = 3.842 A, c_0 = 6.129 A, respectively. In order to investigate the temperature dependence of the electrical characteristics of SnSe_2 single crystals, the Hall effect was measured using Van der pauw method at the temperature of 123 - 403 k along the plane parallel to the C-axis and along the plane perpendicular to the C-axis, respectively.

This paper dealt with the comparision and analysis of the problems of the college entrance examination during the past 15 years(1977-1991), and the experimental contents of the textbooks on high school physics which are currently used. Even if the problems of college entrance examination were closely connected with the experiments of high school textbooks, we can not dare to say that the problems could evaluate the ability for high school students to study the science, because they are mainly multiple-choice tests. It was found by the analysis of the questionaire that high school teachers have more negative opinions on the experimental teaching than middle school teachers. To carry out normally the educational process for the experimental teaching in high school the system of college entrance examination may be improved.

The objectives of this thesis are to investigate and study the present status of the selection of science courses in high school for the Wonkwang University applicants who belong to natural science education group. It is pointed out that the reason and the trend of the preference for the science courses are originated from the education for the extrance examination as a result of the comparison and analysis of the data. The problems which must be solved in the present science education are found out and the suggestions are made for the right direction for the future science education in high school.

From twenty two Korean localities a total of 4,857 Drosophila melanogaster were collected from late August to early October in 1985. Twenty different inversions were found, all of them were identified to be paracentric inversion. There were eight inversions on the second and twelve on the third chromosome. Two types of overlapping inversions were on the right arm of the third chromosome. As a whole of the twenty two populations, the average frequency of wild flies carrying one or more inversions and mean number of inversions per individual were 40.74% and 0.483. The frequency of four common cosmopolitan inversions showed a order of In(2L)t> In(2R)NS> In(3R)P> In(3L)P. Environmental variables such latitude, longitude, and several climatic factors were considered as to where any interrelationships between surrounding conditions and inversion behaviors exist. A correlation between latitude and In(2L)t, In(3L)P, and In(3R)C and between longitude and In(2L)t and In(2R)NS appeared significantly. It seems that the inversion frequencies correlate significantly with temperature and maximum wind speed in autumn in Korean populations of D. melanogaster.

Mathematical model which determines optimum pacing was constructed. It was shown to be effective that each study unit was learned to a level above the inflection point where learning rate was maximum. To determine the pacing practically middle school students studied on the two small study units included in the 'Unit Ⅱ Metabolism' for 5 hours. After each hour formative evaluation was taken. High school students studied on the 'meiosis' from one hour to five hours according to the class. All of the evaluation results showed sigmoidal curves. Estimated time to terminate a unit to maximize the achievement during total study period, was a little longer than the time scheduled in the text. In addition it was shown to be a more serious problem that current study time allocated in the text was insufficient to achieve the high level objectives such as comprehension and application ability.
