We carried out the sensitive high resolution ion microprobe zircon U-Pb age dating and whole rock geochemical analysis of granites in the Gudambong and Sainam geosites, Danyang Geopark. The granites crop out in the western and southern parts of Danyang County, and intruded sedimentary successions of the Yeongweol and Taebaek Groups, respectively. The U-Pb isotopic compositions of zircon from the Gudambong and Sainam granite samples yielded the Cretaceous intrusion ages of $90.4{\pm}0.5Ma(t{\sigma})$ and $90.0{\pm}1.5Ma(t{\sigma})$, respectively. The major and trace elements compositions of the samples showed an affinity of typical A-type granite, indicating their petrogenesis during the late stage of the Bulguksa orogeny or a tectonic dormancy. The geochronologic and geochemical results are identical to those of granites previously reported from the Cretaceous Muamsa and Wolaksan suites.

The aim of this study was to examine fluid excretions and changes in deceased bodies depending on type, location of, and causes of death for hygienic management of funeral homes. Based on the 858 cadavers studied, the average age at the time of death is 68.6 years, 83.0% had illness as the cause of death, and 79.5% passed away in a medical facility. Fluid excretion was observed in 46.2% of the cadavers. In manner of death, 78.8% of deaths -highest percentage- was due to an accident and 10.8% of deaths - lowest percentage- was due to age. Fluid excretion was observed in 46.3% of cadavers from medical facilities, 38.6% of cadavers from homes and 77.4% of cadavers from miscellaneous locations. There were various number of cadavers with recorded immediate, secondary and underlying cause of death; however, the fluid excretion rate was similar. In analyzing the immediate, secondary and underlying cause of death, respiratory and heart disease were the most common causes of death in categories of body organ and system. In terms of fluid excretion, liver disease followed by digestive and circulatory diseases were most common in immediate cause of death. Accidents and miscellaneous circumstances were most common amongst secondary and underlying causes of death for cadavers with fluid excretion. Based on the recorded illnesses of the cadavers, cardiopulmonary failure was most common as evident in 96 cadavers followed by pneumonia and sepsis. Cholangiocarcinoma (73.3%) had the highest rate of fluid excretion followed by pancreatic cancer, severe brain injury and liver cancer amongst categories of illnesses with more than 15 cadavers.

In order to examine cause-specific mortality in Korea by comparing mortality of Japan, various mortality indicators are calculated using 1995 of ficial statistics of twonations. The mortality measures are cause-specific mortality rate by sex, age, andmarital status, cause-specific age-standardized death rate and potential years of lifelost, and their ratios by sex and nation. Items of major causes of death include allcauses (total deaths),tuberculosis, malignant neoplasm, diabetes mellitushypertensive diseases, heart diseases, cerebrovascular diseases, liver diseasestransport accidents, and suicide. Major characteristics of mortality in Korea are asfollows . (1) Death rates from most causes except suicide are higher in Korea thanJapan and especially death rates from tuberculosis, hypertensive diseases, liverdiseases, and transport accidents are higher for economically active Koreans : (2)Death rates from tuberculosis, liver diseases, transport accidents, and malignantneoplasm are salient for Korean children (3) Sex-differentials in mortality fromliver diseases, tuberculosis , and transport accidents are large for economically activeKoreans, because male mortality is higher than female mortality : (4) Suicide ratesare lower for economically active males, and higher for females aged 10s and 20s inKorea than Japan : (5) Death rates are highest f3r divorced or widowed under 45years of age depending on causes, but death rates from all causes are highest fornever-married of the age 45 and over in Korea : and (6) Sex-differentials inmortality are greatest for widowed in Korea and for divorced in Japan.

We investigated the effect of Angelica keiskei ethanol (AKE) extract on cell death in MDA-MB-231 human breast cancer cells. MDA-MB-231 cells were cultured in the presence 125, 150 and 175 ${\mu}g$/mL concentrations of AKE for 24 hours. MTT assays demonstrated that mitochondrial dehydrogenase activities decreased in a dose-dependent manner in MDA-MB-231 cells (p<0.05). In contrast, the proportion of dual staining with Hoechst 33342/ethidium bromide(EtBr) for cell death increased in a dose-dependent manner in MDA-MB-231 cells (p<0.05). In particular, the levels of cell death caused by apoptotic program showed marked increases in the 150 and 175 ${\mu}g$/mL AKE groups, as revealed by flow cytometry. An apoptotic suppressor gene, Bcl-2, significantly decreased at the transcript level (p<0.05). The expression levels of proapoptotic genes, both Bax and caspase 3 significantly increased (p<0.05). Furthermore, the ratio of Bcl-2/Bax mRNA which is considered to be an important indicator of apoptosis, significantly decreased in a dose-dependent manner (p<0.05). These results taken together indicate that, the AKE extract used in this study induces cell death in MDA-MB-231 human breast cancer cells.

Aortic aneurysm has poor prognosis and high mortality, but the incidence of aortic aneurysm is in increasing state. From July, 1986 to July, 1996, we operated on 25 patients with aortic aneurysm and analysed the clinical results and relations between the duration from symptoms onset to operation(Sx-Op), the duration from admission to operation(Adm-Op), preoperative blood pressure, preoperative heart rate and postoperative mortality, retrospectively. The patients were classified as dissecting aneurysm(10 cases), abdominal aortic aneurysm(9 cases), Marfan's syndrome(3 cases), descending thoracic aortic aneurysm(3 cases). The operative technique were graft interposition in 17 cases, Bentall's operation in 4 cases, aneurysm bypass in 2 cases, and wrapping of aorta in 2 cases. Seven patients died of several causes, bleeding in 5 cases, acute renal failure in 1 case and respiratory failure in another one case. Before 1992, the early stage of operation, 6 mortality among 14 operated patients occurred, and after then 1 mortality among 11 operated patients occurred. Eighteen survivors were followed up from 1 to 118 months(mean 50.6 months), and total follow up was 911 patient-months. During the follow up period one patient died of melena 30 months after operation. The other patients did not complain chest pain or dyspnea. The surgical mortality was improved in the late period, and the major cause of death was intraoperative or postoperative bleeding. The Sx-Op duration, the Adm-Op duration, preoperative blood pressure and preoperative heart rate were proven to have no statistical relations with postoperative mortality.

This study is to clarify the comparative relationship and mechanical anisotropy of granite distributed in the Nam-weon on the subject of weathered rock mass sea water surroundings. Artificial weathering test is defined as a test, which controls the weathering rate and agents by controlling the weathering rate and agents by artificial environmental of salt water. Increased weathering degree is large indicated by weathering salt water, such as apparent specific gravity, absorption, porosity, uniaxial compression strength, P-wave velocity, slake durability, shore hardness, indirect tensile strength(brazilian test) and cohesion were measured. As the Weathering salt water proceeds, cracks develope increasingly. A number the cracks affect the rock deformation. Therefore, stress-strain curve of weathered salt water rock in one confined state are quite differ from weathered fresh water rock those. A reason of their deformation type is the formation of micro-cracks and potential porosity caused by artificial weathering test.

Purpose: We studied clinical aspects and courses of patients with pulmonary radioactivity on liver scintigraphy and speculated the mechanism of pulmonary uptake of radiocolloids. Materials and Methods: Forty-nine patients with pulmonary radioactivity were classified into 5 disease groups-liver disease, infection, cancer, ischemic necrosis of liver, etc.- and their presence or absence of chronic liver disease (CLD), Child-Pugh class, serum levels of AST and ALT, results of follow-up liver scintigraphy and clinical course were checked. Results: Of total 49 patients 25 had CLD; there were 23 liver disease patients, 16 infection patients, 7 advanced cancer patients, 2 ischemic necrosis of liver patients, and 1 hemolytic anemia patient. Reversible rise of serum levels of AST and ALT was observed in all patients with liver disease and ischemic necrosis of liver; on one-way ANOVA, these rise were statistically significant (p<0.01). Serum level of ALT of liver disease group patients without CLD was significantly higher than that of infection group patients without CLD (p<0.05). Among 17 patients who underwent follow-up liver scintigraphy, 13 showed no pulmonary radioactivity. Total 12 patients died during follow-up and most of them were terminal cancer patients or CLD patients of Child-Pugh class C. Conclusion: Pulmonary radioactivity of radiocolloid liver scintigraphy could be attributed to the mobilization of reticuloendothelial system (RES) cells by the activation of RES cells in severe infection and terminal cancer, and also by the extensive liver destruction in liver diseases.
