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 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.

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.

Background : The amount of pesticide to be produced and consumed have rapidly growed in Korea and the evidences for pesticide intoxication to human body, natural environment and consumers have evoked. But the studies concerned to pesticide intoxication are inactive. So, we conducted this study about the determinants of awareness and performance for prevention of pesticide intoxication. Methods : The study conduced during the period from July to August 2007 with population consisted of 111 farmers. The toolkit was produced through referencing previous studies. Data analysis was performed with t-test, ANOVA and multiple linear regression analysis using SPSS 14.0K program. Results : The mean awareness score was 3.07 ± 0.75, the mean of total performance score was 2.72 ± 0.69, mean of subtotal performance score for keeping safety guideline was 2.72 ± 0.69 and mean of subtotal performance score for wearing protective equipments was 2.43 ± 0.83. Awareness score was associated with sex, age and family income. Female, older people and people with high income were tend to show low awareness score. Performance score was associated with sex, family income and educational level. Female, people with low education and high income were tend to show low performance score. Conclusion : We concluded that educational effort for noticing the harmful affects of pesticide, the importance of keeping safety guideline and wearing protective equipments to farmers especially female, older people, people with low education and high income were significant factors for prevention of pesticide intoxication.

Objectives : We evaluated the efficacy of ramosetron and ondansetron for preventing postoperative nausea and vomiting (PONV) in laparoscopic colectomy. Methods and Materials : Eighty patients who received laparoscopic colectomy were randomly divided into two groups: R group (ramosetron 0.1mg PO) and O group (ondansetron 4mg twice IV). Injection or oral medication was administered before the induction of anesthesia in each group. Injection was administered at the end of surgery in O group. General anesthesia was induced using propofol and rocuronium, and maintained with sevoflurane, remifentanil and air (FiO2 0.5), We investigated the incidences of PONV in each group by the Rhodes index of nausea, vomiting and retching (RINVR) at postoperative 6 and 24 hours. Results : The incidence of PONV was not different between group at each time points after surgery (at postoperative 6 hours: 20% in group R, 17.5% in group 0, at postoperative 24 hours; 12.5% in group R, 7.5% in group 0). There was no difference in the severity of PONV, satisfaction, rescue drug usage. Conclusion : Prophylactic therapy with ramosetron is as effective as conventional prophylactic therapy with ondansetron for preventing PONV in general anesthesia for laparoscopic colectomy.
