The real economy and the financial economy complement each other to create a complete economic system. Therefore, the dynamic effect between domestic real economy and financial economy is studied by using structural vector autoregressive (SVAR). International oil price variables are introduced into the SVAR model, which plays a dynamic role between output, consumer price index, money supply, short-term interest rate, exchange rate and stock price. The dynamic effects between the real economy and the financial economy show that both have important implications. This paper discusses the two-way relationship between the real economy and the financial economy, probes into the theoretical basis of the real economy, and discusses how the financial economy promotes the development of the real economy.

The carcinogenicity of PAH (Polycyclic Aromatic Hydrocarbon) was studied with the molecular orbital method in this paper. The theoretical calculations of molecular orbitals are based on the simple Huckel method. The model of carcinogenicity of PAH was followed by the "bay region" model. This model shows that K region binds with enzymes, and that epoxidations occur A and B region. As reactivity indices, frontier electron density, superdelocalizability and approximate superdelocalizability are calculated. Thirty-nine compounds were tested in this paper. The results are as follows: 1. The frontier electron density and approximate superdelocalizability do not show good correlations with carcinogenicity of PAH in this paper. 2. A to B ratios of the approximate superdelocalizability were located between values of 0.9960 and 1.0070 in carcinogenic compounds. (K+A+B) values of carcinogenic compounds were generally larger than 5.7. 3. Theoretically, it is not easy to estimate the strength of carcinogenicity. However, the superdelocalizability of (K+A+B) region gives a good correlation with the carcinogenicity of PAH studied. Therefore, K, A, and B regions of those compounds are all related to the carcinogenicity.

Korean hemorrhagic fever (KHF) was recognized in Korea for the first time in 1951 during Korean War among United Nations troops although similar diseases to KHF had been reported as Hemorrhagic nephroso-nephritis in Russia, as Epidemic hemorrhagic fever in China, as Nephropathia epidemica in Scandinavia and as Epidemic hemorrhagic fever in Eastern Europe and in Japan. The etiologic agent of Korean hemorrhagic fever was first discovered from lung tissue of Apodemus agrarius by Lee and Lee in 1976 and they had isolated the same agent from KHF patient's sera and had succeeded the propagation of the virus in Apodemus agrarius and the virus was named Hantaan virus after Hantaan river. The etiological relationship had been shown by serologic means among above mentioned similar diseases, and the working group on Hemorrhagic fever with renal syndrome at a WHO meeting in 1982 recommended the above mentioned diseases with different names should be referred to as "Hemorrhagic fever with renal syndrome (HFRS)." In 1981, Hantaan virus was successfully propagated in an in vitro system in A549 cells originated from alveolar epithelial cells of human lung cancer, and later in Vero E6 cells originated from African green monkey renal epithelial cells. With the aid of this in vitro growth, the study of virus isolation and morphological and physico-chemical Properties of the virus became easier. This report describes the growth curve of Vero E6 cells and the growth curve of Hantaan virus in Vero E6 cells. The data obtained from tissue culture flasks made in Korea was compared with the data obtained from tissue culture flasks made in U.S.A. The results are summarized as follows. 1. There were no differences in durability and in stability of pH of culture media in tissue culture flasks between U.S. Costar flask and Korean GCMEC flask. The pH of culture media was maintained between 7.1 and 7.6 for 14 days at 5 % CO₂ incubator. 2. Vero E6 cells were propagated well both in Costar and GCMEC tissue culture flasks, and the propagation reached peak level on 3rd day after inoculation. 3. Hantaan virus were propagated well in Vero E6 cells and the maximum yield of virus were on 8th day after inoculation of virus. The maximum infectious unit of virus in tissue culture flask containing media with 5% fetal calf serum was 10^(7-8)/ml, and that in flask containing 5% of 0.4% bovine albumin was 10^(6-7)/ml. There was no difference between the value obtained in Costar and GCMEC flask. 4. 50% of the Vero E6 cells were infected on 3rd day after inoculation of Hantaan virus, and 95% on 5th day.
