The eminent brother doctors Cho-Gaek Hur (Young Hur) and Cho-Sam Hur (Eon Hur) represent the medical tradition of the southeastern region of Mt. Jirisan incluiding Sancheong. This study investigated and examined their herediatary testimonies and medico-historical facts described in the literature tale, genealogy and family collection of works. At an early age after their family run away to the southern region from the harm of political struggle, they gave up taking the highest-level state examination to recruit ranking officials and set their heart on learning medicine. Their choice of medicine was the second best plan for the survival of their family and descendents from the influence of their ancestors who suffered from the party strife during the late Joseon Dynasty. The case is a good example of the deliberate action of the nobility intellectuals since the late Goryeo and early Joseon dynasties to who made attempts to have the minimum elegance and cause while securing livelihood after they have been collapsed politically. The tale of Cho-Gaek and Cho-Sam is a typical story of eminent doctors which combined reality and fiction about the persons who had outstanding medical skills. In the tale, the elder brother was good at herbal prescriptions and the younger brother was good at acupuncture, contrasting the treatment of administrative internal medicine and insertive acupuncture treatment. It shows that the prepositions for the choice of the treatment method for the public during that period were safety and fast efficacy. In their old age, they wrote a book titled Jinyangsinbang. Another Jinwoosinbang is estimated as a different kind of copy, which was a medical writing from experience that derived from the same original book as Jinyangsinbang. written by Cho-Gaek Hur and it is a valuable medical material that possesses the distinct features of the local medicine during the late Joseon Dynasty. Most of the contents are variations in application using the basis of Dongeuibogam, forming the roots of the traditional Korean medicine in Sancheong region together with the medical activities of the Hur brothers.

The potential antiviral effects of the culture filtrates (CF) from Serratia marcescens strain Gsm01 against yellow strain of Cucumber mosaic virus (CMV-Y) were investigated. The culture filtrate of S. marcescens strain Gsm01 applied on Chenopodium amaranticolor showed high inhibitory activity, likewise no necrosis appeared when applied on the tobacco plants 2 days before CMV-Y inoculation. When plants were challenge inoculated with CMV-Y for eighteen days, the disease incidence in plants with culture filtrate of S. marcescens Gsm01 did not exceed 59%, whereas 100% of control plants were severely infected. The results of double antibody sandwich-enzyme linked immunosorbent assay (DAS-ELISA), reverse transcriptase polymerase chain reaction (RT-PCR), dot blotting, and western blotting showed that culture filtrate treatment highly affected the accumulation of CMV-Y or its CP protein gene in the treated plant leaves. It was also observed that the culture filtrate had no RNase activity on genomic RNAs of CMV-Y, suggesting that culture filtrate may not contain ribosome inactivating proteins (RIPs) or proteins with RNase activity. These data shows that culture filtrate of S. marcescens strain Gsm01 seems to be a promising source of antiviral substance for the practical use.

Enterotoxigenic Escherichia coli (ETEC) strains producing each F4, F5, F6 and F41 fimbriae were lysed by GI24 peptide. The lysate cells were used as ETEC vaccine candidate. This study was carried out to examine whether intramuscular (im) immunization of pregnant sows with the novel vaccine candidate could effectively protect their neonatal piglets against ETEC colibacillosis. All pregnant sows were primed at 11 weeks and were boosted at 14 weeks of pregnancy. Group A sows were im inoculated with PBS. Group B sows were im immunized with $2{\times}10^9$ the mixture. Seral IgG, colostral IgA and IgG titers from group B sows, and seral IgG and IgA levels in group B piglets were significantly higher than those of group A sows and piglets, respectively. After challenge with wild-type ETEC, diarrhea and mortality was not observed in group B piglets. However, diarrhea was observed in 66.7% of group A piglets, and 33.3% mortality was observed. These findings indicate that im immunization of sows with the mixture of the novel vaccine candidate can effectively protect their offspring from ETEC colibacillosis.

Radiation generating devices must be properly shielded for their safe application. Although institutes such as US National Bureau of Standards and National Council on Radiation Protection and Measurements (NCRP) have provided guidelines for shielding X-ray tube of various purposes, industry people tend to rely on 'Half Value Layer (HVL) method' which requires relatively simple calculation compared to the case of those guidelines. The method is based on the fact that the intensity, dose, and air kerma of narrow beam incident on shielding wall decreases by about half as the beam penetrates the HVL thickness of the wall. One can adjust shielding wall thickness to satisfy outside wall dose or air kerma requirements with this calculation. However, this may not always be the case because 1) The strict definition of HVL deals with only Intensity, 2) The situation is different when the beam is not 'narrow'; the beam quality inside the wall is distorted and related changes on outside wall dose or air kerma such as buildup effect occurs. Therefore, sometimes more careful research should be done in order to verify the effect of shielding specific radiation generating device. High energy X-ray tubes which is operated at the voltage above 400 kV that are used for 'heavy' nondestructive inspection is an example. People have less experience in running and shielding such device than in the case of widely-used low energy X-ray tubes operated at the voltage below 300 kV. In this study, Air Kerma value per week, outside concrete shielding wall of various thickness surrounding 450 kVp X-ray tube were calculated using MCNP simulation with the aid of Geometry Splitting method which is a famous Variance Reduction technique. The comparison between simulated result, HVL method result, and NCRP Report 147 safety goal $0.02mGy\;wk^{-1}$ on Air Kerma for the place where the public are free to pass showed that concrete wall of thickness 80 cm is needed to achieve the safety goal. Essentially same result was obtained from the application of HVL method except that it suggest the need of additional 5 cm concrete wall thickness. Therefore, employing the result from HVL method calculation as an conservative upper limit of concrete shielding wall thickness was found to be useful; It would be easy, economic, and reasonable way to set shielding wall thickness.
