Traditional method of pulpectomy for a necrotic primary anterior tooth was done on lingual side. But it could not recover the discoloration of crown effectively. For the purpose of treating the discoloration of crown after lingual pulpectomy, additional methods of crown restoration were needed like : celluloid crown, open-faced crown, rasin-faced crown. Neverthless, these kinds of complete coverage methods had some disadvantages such as possibility of tooth fracture by increased tooth preparation. In order to overcome the shortcomings of lingual pulpectomy, labial treatment could be considered as an alternative. It is a method that treats necrotic pulp through the labial access opening. After finishing the pulp treatment, discolored labial tooth structure was removed extending from access opening. Discoloration of deep area could be masked effectively using opaque sealant. Cavity on labial side was restored with composite resin. This labial approach method has several advantages. First, it gives a direct vision for effective pulp treatment which is also very useful for children with poor behavior. Second, most of lingual tooth structure could be saved and occlusal contact of lingual surface remains undisrupted. Only nonfunctional discolored labial surface may removed. Third, complete removal of discolored part of a labial tooth and immediate resin restoration could be done effectively after pulp treatment. Moreover, it also could be used for pulp treatment having serious dental caries on labial surface with sound lingual tooth structure. This report presents cases with discolored upper anteior primary tooth, approaching labial side with successful restoration.

In Goryeo Dynasty age ordinary women had preferred to light make-up, but giseng bundae Make-up(dark make up). They had hair-style as like chumagye, ahhwangye and jocheongye. But considering the makeup of the Song Dynasty, and the difference was similar Huh style. The Make-up artists in Song Dynasty usually used elegant and mild color, but the had preferred splendid style in Tang dynasty. The make-up & hair artists of TV Drama have an inclination to adopt contemporary trendy style. The make up style of Song Dynasty was different from the one of Goryeo Dynasty. There were similarities of hair style between these.

This experiment was carried out to determine optimal concentration of organic liquids for the improvement of antioxidant in pepper. As human beings enter the age of 100, they are naturally recognized as a standard of high quality agricultural products for safety and improvement of functional materials. Tomatoes are among the most consumed vegetables in the world and there is a growing interest in varieties with high functional content. However, there is a limit to the improvement of functional materials of certain varieties, so it is necessary to study the improvement of materials by cultivation physiology and environmental conditions. The test material was sown on March 15th in Wanju province and on June 15th in rain shelter house using pepper “suppermanidda” varieties. To investigate the optimum concentration of organic liquids for the improvement of antioxidant, 15 kinds of treatments were carried out including control, tomato liquid fertilizer etc. The liquid fertilizer of organic material was treated with 6 times of irrigation, and the analysis of nutrients and antioxidant was done by harvesting pepper on the September 10th. The contents of beta-carotene was increased in the T3, T4, T12 treatments, vitamin C was in the P14 treatments, flavonoid, polyphenol were in the P12 treatment compared to the control. In T12 treatment, flavonoid increased by 115.9%, polyphenol by 121.7%, beta-carotene by 117.2% and vitamin C by 136.1% compared to the control. There was no significant difference in the growth characteristics and characteristics of pepper fruit of pepper according to liquid fertilizer treatment. Therefore, it has been confirmed that the organic antioxidant is affected by the liquid fertilizer treatments of organic materials and it is necessary to study the environmental conditions such as temperature, moisture and photosynthesis.

목적: 병리학적 소견을 바탕으로 IgA 신증 환자의 예후를 예측하고자 여러 분류들이 소개되었다. 최근에 소개된 Oxford 분류법과 전자현미경 소견을 이용하여 예후인자와 연관성 및 신생존의 예측 능력을 알아보고자 하였다. 방법: 1997년부터 2007년까지 IgA 신증으로 진단된 환자213명을 후향적으로 조사하여 병리의사가 Oxford 분류법과 전자현미경 소견을 바탕으로 재분류하고 연령, 성별, 단백뇨, 신기능 저하, 고혈압 등과의 연관성 및 신생존율 분석에 적용하였다. 결과: eGFR은 Oxford 분류법의 M, S, E, T 모든 항목과 의미 있는 연관성을 보여 주었고 24시간 소변 단백/크레아티닌 비는 S, E, T 모든 항목과 의미 있는 연관성을 보여 주었다. T 항목만이 신생존율과 통계적으로 의미가 있었으며 전자현미경 소견은 신생존율을 예측하는 능력은 보이지 않았다. 결론: 본 연구에서는 Oxford 분류법의 T 항목인 tubular atrophy/interstitial fibrosis가 단백뇨의 정도를 잘 반영했을 뿐만 아니라 신기능의 악화를 예측할 수 있는 강력한 평가 항목임을 보여주었다. Background/Aims: The Oxford classification of immunoglobulin A nephropathy (IgAN) is a pathology-based prognostic classification system. However, further study is needed to determine its validity. We studied the relationships between the Oxford classification and established prognostic factors and renal survival. We also examined associations between electron microscopy findings and these parameters. Methods: We reviewed and reclassified 213 patients who were diagnosed with IgAN from 1997 to 2007 using the Oxford and World Health Organization (WHO) classification systems. The patients were also categorized by a pathologist using electron microscopy findings, including foot process fusion, glomerular basement membrane thickness, and electron-dense deposits. We examined the correlations between light and electron microscopy data and known prognostic factors (e.g., age, sex, proteinuria, serum creatinine, estimated glomerular filtration rate [eGFR], and blood pressure). The same procedure was applied to renal survival. Results: Patient age increased with the grades of segmental sclerosis (S) and tubular atrophy/interstitial fibrosis (T) (p < 0.05). eGFR decreased significantly with increasing mesangial hypercellularity (M) (p = 0.0034), S (p = 0.0003), endocapillary hypercellularity (E) (p = 0.0411), and T (p < 0.0001). MSET differed significantly by sex (p < 0.0001). The 24-h urine protein/creatinine ratio increased significantly with the degrees of S (p = 0.036), E (p = 0.0155), and T (p = 0.015). The serum creatinine level was significantly higher in patients with T2 than T1 or T0 (p < 0.0001). At the time of biopsy, the degree of tubular atrophy/interstitial fibrosis affected the doubling of serum creatinine or end-stage renal disease. However, the electron microscopy findings did not predict the renal outcome. Conclusions: Our study suggests that tubular atrophy/interstitial fibrosis is significantly associated with proteinuria and renal progression in IgAN.

Hexagonal barium ferrite ($BaFe_{12}O_{19}$) nano-particles have been successfully fabricated by spraypylorysis process. $BaFe_{12}O_{19}$ precursor solutions were synthesized by self-assembly method. Diethyleneamine (DEA) surfactant was used to fabricate the micelle structure of Ba-DEA complex under various DEA concentrations. $BaFe_{12}O_{19}$ powders were synthesized with addition of Fe ions to Ba-DEA complex and then fabricated $BaFe_{12}O_{19}$ powders by spray-pyrolysis process at the temperature range of $800{\sim}1000^{\circ}C$. The molar ratio of Ba/DEA and heat-treatment temperatures significantly affected the magnetic properties and morphology of $BaFe_{12}O_{19}$ powders. $BaFe_{12}O_{19}$ powders synthesized with Ba/DEA molar ratio of 1 and heat-treated at $900^{\circ}C$ showed the coercive forces (iHc) of 4.2 kOe with average crystal size of about 100 nm.

Rare-earth elements were doped with Mg to enhance the temperature stability of dielectric properties of BaTiO₃ for its application to MLCC (Multi-Layer Ceramic Capacitor). The additives strongly affect both grain growth and densification behaviors during sintering, and hence dielectric properties. The additive effects therefore should be examined in each system with different additives. This study investigated the crystal structure, grain growth and densification behaviors and related variations in dielectric constant with respect to sintering temperature. Dielectric constant appears to be varied with grain size in a temperature range between 1200 and 1300℃, suggesting the importance of grain size control. The temperature dependence of grain size variation was well explained by an established theory correlating the grain growth behavior with grain boundary structure. This accordance provides a basis for sintering technique to control grain growth thus to improve dielectric constant in rare-earth doped BaTiO₃.
