The purpose of this study was the reaching test of restorative glass according to composition. Mixtures of SrF₂, CaF₂and SiO₂were fused in platinum crucible. The glasses were ground and fraction which passed through a 400 mesh (38㎛) sieve were collected. The powder specimens were analyzed by a DTA and XRD. Then powder specimen were inserted to D. I. water with various of dissolution time and composition at 37℃. Fluoride ion, cation release, solubility, and pH change were estimated. It was clear that the glasses were formed except S0.65. In S0.40, Tg, Ts, and Tc were 630, 672, and 813℃ respectively. In initial 0.5 hrs., amounts of released fluoride ion and cation were about 90% of total released amounts and released rate was decreased with dissolution time. Amount of released fluoride ion and cation were increased with decreasing SiO₂ in glass filler. And released rate was decreased rapidly by adding CaF₂. This was caused by structural variation in glass filler. Solubility was similar tendency with ion released. The pH of D.I. water was 4.5. But in intial 0.5 hrs., pH was 8.2∼9.8., and decreased according to dissolution time. This is caused by ionic changing with cation and H* ion.

Tris[4-(2-hydroxy-3-methacryloxypropoxy)phenyl]methane(THMPM) was prepared easily from triphenylolmethane triglycidyl ether in good yield. As compared with composite resin formulated with difunctional bis-GMA, the physical properties of a newly developed composite resin formulated with trifunctional THMPM was evaluated. Cytotoxicity and acute toxicity of composite resin based on trifunctional THMPM evaluated according to ISO standard method. The depth of cure of the composite resin based THMPM was higher than that of the bis-GMA composite. There were no significant differences in flexural strength and water sorption between the composites resin based on THMPM and bis-GMA. The water-solubility value for the light-activated composite resins formulated with THMPM was much lower than that for a control bis-GMA composite. According to cytotoxicity evaluation, the composite resin based on THMPM showed very mild cytotoxicity with the response index of between 0/0 and 1/0. No acute toxicity of composite resin formulated with trifunctional THMPM was also observed. It is believed that THMPM is promising candidate for application as a photocurable dental composite resin.

The Daehan-maeil shinbo (the Korean Daily News) was first published in 1094 and ceased in 1910. It was published in three different languages, i.e., Korean, chinese characters and Korean, and English. In those days Korean sovereignty was at a crisis by the imminent Japanese invasion, and this paper campaigned for women's education from the view point of the patriotic enlightenment movement. This article, therefore, attempted to discuss various aspects of the women's education campaign. 1. Women who can bring up patriotic children should be educated since it is a shortcut to a national revival. 2. Home education is so important that women have initiatives in it. 3. Traditional customs can be abolished through the establishment of girls' school, which obstinate conservatives prohibit. 4. Textbooks for women's education should be writtern in Korean, not in Chinese characters. 5. The enthusiasm for women's education is so high that many people donate their treasures of gold and silver, while many women advance their opinions on education.

In hydrology, rainfalls apply to mean every type of rains which were dropped from clouds and condensed into waters. While the rains made from during the condensing process are studied in meteorology, the raindrops on the ground are the subject of hydrology. For background knowledge, this study has collected research materials and data on rainfalls for 20years in Mok-Po and Chang-Hung. Then, by surveying the existing articles and analysing experimental records, this paper tried to predict the accurate amount of the rainfalls for the limited time. The methods used for foretelling rainfalls optimal probability are as follows; Normal Distribution Methods, Log Normal Distribution Method, Moment Method, Gumbel-Chow Method, Iwai Method are applied. The methods for significant statistic results are as follows; Talbot, Sherman, Japanese and Semi-log are used. The computer was used to figure out the invariable number for the methods while the most proper formula was selected through comparing χ ²-test number and standard reduction rate. The formulas for rainfall optimal probability are as follows; In Mok-Po, Normal Distribution Method is used for 3, 5, 10, 200 years and Gumbel-Chow is taken into account for 20, 30, 50, 100 years. In Chang-Hung, Gumbel-Chow was used for 3 years and thanks to the smallest error, Iwai was used for more than 5 years. After comparing standard error with χ ²-test number, Japanese was appropriate in Mok-Po for 3, 5 years and Sherman for over 10 years. In Chang- Hung, Japanese was most useful from 3 to 20 years and Sherman for over 30 years. In this study, the formulas suggested for optimal probability have 97.24% significancy for Mok-Po and 97.83% significancy for Chang-hung. Therefore, the offered formulas are meaningful to consider in constructing hydrological buildings in that they have higher optimal probability than the existing ones and they have similar predictive results with ones by meteorological observatory. The formulas offered in this study are expected to have significancy according to rainfall frequency, rainfall duration and rainfall intensity. Furthermore, they have useful value related with I.D.F correlation.
