In this study, we developed a new methodology to measure the degree of guarantee of old-age earnings of public pension. In addition, this method was used to compare the effect of securing the old-age income between the public reverse mortgage and the public pension. In this study, the proposed new methodology is the "contribution to guarantee of old-age income," which is a comprehensive single index covering both income replacement rate and eligibility. Based on this methodology, we estimated the income guarantee effect of national pension, basic pension, and public reverse mortgage, all of which are representative public pensions in Korea. The results of the estimation of the contribution of the old-age income guarantee show that the contribution of the public reverse mortgage was 31.3%, which was about two times higher than the basic pension at 15.0% and the national pension at 14.5%. This means that if the public reverse mortgage is additionally applied to the public pension system, the current senior citizen family generation can increase the contribution of the old-age income guarantee up to 60.8%.

The single dose toxicity of Jengjengamiyjintang, a herbal drug for duodenal ulcer was evaluated in male and female Sprague-Dawley (SD) rats. Jengjengamiyjintang was once administered to both sexes of rats at the dose levels of 2000, 1000, 500, 250 and 125mg/kg for oral route according to KFDA guidelines for single dose toxicity test (1999-61). In addition, vehicle control group was added in order to compare clinical signs, body weight changes and abnormal necropsy findings. After single administration, clinical signs were observed every twice a day for 14 days and body weights were measured 5 times including initial measurement on day 0. When observation period was over, the animals were sacrificed and macroscopic examination of major organs was conducted. Neither significant clinical signs nor death after administration was observed during the observation periods except for soft feces or diarrhea that were restricted to Day 1 of 2000 and 1000mg/kg-dosing groups. Although some accidental findings such as gross and histopathological changes of lung that were demonstrated in some animals of all experimental groups including vehicle control group, no abnormal necropsy findings and changes of body weight were observed at terminal necropsy in both sexes. From these results, it is considered that $LD_{50}$ of Jengjengamiyjintang is over 2000mg/kg in oral administration in both sexes of rats and approximated lethal dose was considered over 2000mg/kg.

Chelidonii Herba (Baekgulchae in Korean: CHE), a commonly used herb in Korea, Japan and China, is widely used in the treatment of stomach cancer, jaundice, gastric ulcer, edema and pain of stomach. In the present study, we demonstrated that CHE induces apoptosis in AGS cells, human stomach adenocarcinoma cell line. One of the most important recent advances in cancer research is the recognition that apoptosis plays a major role in both tumor formation and treatment response, In this study, CHE caused a decrease of viability in AGC cells. When AGS cells were treated with CHE, cells showed dose-dependent manner apoptotic cell death. Increased apoptotic cell death, exposured to CHE, resulted from induction of Bad translocation to mitochondria, cytochrome-c release from mitochondria to cytosol, activation of caspase-3, 8, 9, and PARP cleavage. These results suggest that CHE may be potential therapeutic approach in the clinical management of stomach adenocarcinoma.

실리콘 표면에 이온화된 $N_2$ 가스를 입사한 후 어닐링을 통해서 $SiN_x$ 나노구조를 형성하였다. 원자힘 현미경으로 관찰한 결과 이 나노구조의 밀도는 $3\times10^{10}/cm^2$였으며, 가로 크기는 40$\sim$60 nm 이고 높이는 약 15 nm 임을 알 수 있었다. 엑스선광전자 분광기술을 이용하여 이 나노구조의 화학상태를 측정하였는데, 입사하는 이온화된 $N_2$의 단위시간당 양이 증가함에 따라서 화학상태가 $SiN_x$에서 $Si_3N_4\;+\;SiN_x$형태로 변화함을 알 수 있었다. 열처리를 한 시료를 투과전자 현미경으로 측정된 결과는 $SiN_x$ 나노구조를 내부에 Si 나노 결정이 형성된 것을 보여주었다. 광여기 발광특성에서 관찰된 400 nm파장의 스펙트럼은 Si 나노결정의 크기를 고려할 때 나노결정과 $SiN_x$ 나노구조 사이의 계면상태에서 기인한 것으로 생각된다. Nanostructures of $SiN_x$ were made by bombardment of ionized $N_2$ on Si surface and subsequent annealing. Atomic force micrograph showed the density of $SiN_x$ nanostructures was $3\times10^{10}/cm^2$. Their lateral size and height were 40$\sim$60 nm and 15 nm, respectively. The chemical state of the nanostructure was measured using X-ray photoelectron spectroscopy, which changed from $SiN_x$ to $Si_3N_4\;+\;SiN_x$ as the bombarding ionized gas current increases. Upon annealing, transmission electron micrograph showed a clear evidence for crystalline Si phase formation inside the $SiN_x$ nanostructures. Photoluminescence peak observed at around 400nm was thought to be originated from the interface states between the nanocrystalline Si and surrounding $SiN_x$ nanostructures.

Purpose : The object of this study was to observe the suppressive effects of Yijintang-gamibang (YJGMB), Yijintang with Atractylodis Rhizoma, Massa Medicata Fermentata, Hordei Fructus Germiniatus, and Coptidis Rhizoma. YJGMB has been traditionally used in Korean medicine for treating various digestive diseases. We tested it on the rat reflux esophagitis (RE) induced by pylorus and forestomach ligation in rats as compared with omeprazole, a well-known proton pump inhibitor. Method : Three different dosages of YJGMB 200, 100 and 50mg/kg, were orally pretreated once a day for 28 days before pylorus and forestomach ligation. Seven groups, each of 8 rats per group were used in the study. Six hours after pylorus and forestomach ligation, changes of the stomach and esophagus lesion areas, gastric volumes, acid and pepsin outputs, invasive lesion percentages, fundic mucosa and total thicknesses were measured as histomorphometry. The results were compared with omeprazole, antioxidant and proton pump inhibitor, and 30 and 10mg/kg treated groups in which the effects on RE were already confirmed. Results : As results of pylorus and forestomach ligation, marked increases of esophageal and gastric mucosa lesion areas, gastric volumes, acid outputs, pepsin outputs were observed with histopathological changes of RE, such as hemorrhages, ulcerative lesions and edematous changes on the fundic mucosa. However, these pylorus and forestomach ligation-induced RE were dose-dependently inhibited by treatment of 200, 100 and 50mg/kg of YJGMB. YJGMB 200mg/kg showed similar protective effects as compared with 30mg/kg of omeprazole in the present study, and more favorable effects were observed in 50mg/kg of YJGMB treated rats as compared with omeprazole 10mg/kg in the present study. Conclusion : The results obtained in this study suggest that YJGMB has favorable protective effects on the RE induced by pylorus and forestomach ligation. Therefore, it is expected that YJGMB will also show favorable effects on RE corresponding well to the suggestion of traditional Korean medicine. However, more detailed mechanism studies should be conducted in future with the screening of the biological active chemical compounds in herbs.
