황남대총 98호분 북분과 남분에서 출토된 유리시료 40점에 대한 과학적인 분석을 실시하였다. 유리의 성분조성은 주사전자현미경-에너지분산형분광기(SEM-EDS)를 사용하여 정량분석 하였고 다변량해석법을 통하여 시료를 분류하였다. 그 결과 시료 40점 모두 Na₂O를 약 20%정도 함유한 소다-석회(Na₂O CaO-SiO₂)유리임을 확인하였으며, 다시 5개 주성분(SiO₂, AI₂O₃, Na₂O, CaO, K₂O)으로 다변량해석[주성분분석(PCA)]을 실시한 결과 2개의 群으로 분류되었다. I 群에 포함된 시료는 Al₂O₃의 농도가 9.7%로 높고 CaO의 농도는 2.2%인데 비하여 Ⅱ群에서는 각각 3.2%,4.9%의 범위로 나타났다. 특히 시료 No.12의 노란 색으로 편석된 부분을 미소부위 XRD로 분석한 결과 PbSnO₃임을 국내 최초로 확인할 수 있었다. 鉛을 함유한 시료 중 No.12, 17은 열이온화질량분석기(TIMS)로 납동위원소비를 측정하였고 선형판별식 분석법(SLDA)을 이용하여 납의 산지를 추정하였다. 그 결과 각각 중국 남부, 한국 남부의 납광석을 사용한 것으로 나타났다. Elemental analysis of 40 glass samples from the Northern Tomb and the Southern Tomb of Hwangnam-daechong No. 98 was performed. Fourteen compositions of each sample were analyzed quantitatively by SEM-EDS and glass samples were classified by multivariate analysis such as PCA. All of 40 samples were confirmed to be Na₂O CaO-SiO₂ system with about 20% of Na₂O. Samples were classified into two groups by doing PCA on concentrations of 5 major elements (SiO₂, AI₂O₃, Na₂O, CaO, K₂O). Samples included in group I showed the concentration of AI₂O₃ is about 9.7% and that of CaO, about 2.2%. In group II, concentration of Al₂O₃ is about 3.2% and that of CaO, about 4.9%. Especially yellow grains embedded in sample No.12 were shown to be PbSnO₃ by micro XRD, which was the first coloring material ever found in Korea. Lead isotope ratios of samples No.12 and No.17 which contained lead were measured by TIMS. The origin of lead was traced by means of multivariate analysis such as SLDA. The result showed that lead from southern China and southern Korea had been used for making glass.

The rainwater samples were collected from the 1100 Site of Mt. Halla and Cheju city during the period of March in 1997 to August in 1998, and the major soluble ions were analyzed and their analytical confidence has been investigated. The volume weighted mean values of pH in 1100 Site and Cheju city were 487 and 4.82, respectively, and those of electrical conductivity were 16.0 and 23.3 μS/cm. The mean concentrations of ions in 1100 Site were in the order of Cl^(-)>Na^(+)>SO₄^(2-)>NH₄^(+)>H^(+)>NO₃^(-)>Mg^(2+)>Ca^(2+)>K^(2+)>HCOO^(-)>CH₃COO^(-)>F^(-)>HCO₃^(-)>CH₃SO₃^(-), and those in Cheju city were the same order except that NO₃^(-) was higher than H^(+). The comparison between several correlation coefficients has been applied for the investigation of analytical confidence, such as equivalent concentrations sum, the measured and calculated conductivity, and the acid fraction. The correlation coefficients between cation and anion equivalent concentrations sum were 0.981 and 0.960, respectively, in 1100 Site and Cheju city, and those of the calculated and measured electric conductivity in two regions were 0.989 and 0.993, respectively, so that the analytical data has been shown to be in good reliabilities. Also, the correlation coefficients between the acid fractions from the equivalent concentrations of ions and those from the measured pH and electric conductivity were 0.966 and 0.936, respectively, in two areas, so that these results also have shown a quite satisfactory analytical confidence.

We determined for IgE in serum based on the enzyme-linked immunosorbent assay(ELISA) in vivo after intraperitoneal injection of Solanum lyratum extract for 14 days. The experiment showed as well whole spleen cells that Solanum lyratum extract enhanced IgE production in vivo. Solanum lyratum extract significantly facilitated the production of IgE by LPS-stimulated murine spleen cells. Solanum lyratum THUNB. also enhanced IgE production from mouse whole spleen cells. Lypopolysaccharide(LPS) stimulated IgE production was enhanced 1.4-fold to 2.7-fold by the addition of Solanum lyratum extract over a period of 7 days.

A new method for the layer charge determination in the 2:1 type layered aluminosilicate was proposed. As a test material vermiculite was chosen and its n-alkyldiammonium intercatation compounds were prepared by the ion exchange reaction. The layer charge density per formula unit (ξ) was estimated from the critical carbon number of alkyldiammonium ion during the structure phase transition (from monolayer to bilayer structure). The prepared compounds were also characterized by IR, XRD and Thermal Analysis.

MgAl-layered double hydroxides, [Mg_(1-x)Al_x(OH)_2](CO_3^2-)_X/2·yH_2O were synthesized by the co-precipitation methods and with variation of charge density which has a very important role to he determined the physicochemical properties of layered materials. From the results of XRD analysis, we found that the lattice parameter and the unit cell volume decreased linearly to the amount of Al substituent in the vicinity of x = 0.0667 and x = 0.33, but those were nearly constant. when the x are far from these vicinity. Especially, Mg(OH)_2 peak also shows besides LDH phases in a compound with a small x value of 0.0667. From these results, the most appropriate condition to synthesis the LDH single phase was revealed to be x = 0.1 - 0.33.

Allergic rhinitis is characterized by rhinorrhea, sneezing and nasal obstruction. Allergic rhinitis increases because of developments of diagnostic techniqhe, environmental change, especially industrialization. Recently people have studied on allergic rhinitis. We studied 107 allergic rhinitis patients with SBJ from June. 2002 to December, 2002. There was a significant effect of SBJ on allergic rhinitis. So, we suggested the clinical effect of SBJ on allergic rhinitis.

A child abuse case of an 18 month-old baby girl with multiple fractures is reported. A comprehensive psychiatric and pediatric diagnostic work-up was carried out, and psychodynamic and family dynamic issues were presented in detail. A therapeutic intervention by pediatric-psychiatric team was attempted, but thwarted by the lack of father's cooperation. It is suggested that child abuse should be considered a major medical social problem in Korea too.
