The purpose of this study was to examine the anti-inflammatory effects of ginger and processed (Beopje) ginger on colitis induced by 2.5% dextran sulfate sodium (DSS) in Balb/c mice. Beopje means a process that herbal medicines are treated by a specific Korean traditional method in order to obtain better pharmacological effects. Mice were fed saline or two different doses of ethanol extracts (ginger and processed (Beopje) ginger) once a day for 14 days. Colitis was induced from day 7 to 14 via administration of 2.5% DSS in drinking water. Experimental animals were divided into four groups: Nor (Normal, 200 ${\mu}L$ of saline without 2.5% DSS-treated group), Con (Control, 200 ${\mu}L$ of saline and 2.5% DSS treated group), G (500 mg/kg of ginger and 2.5% DSS treated group), and BG (500 mg/kg of Beopje ginger and 2.5% DSS treated group). Body weights of both ginger-administered groups increased compared to the control. Colon length increased to 7.6, and 8.0 cm in the G and BG groups, respectively, whereas that of control was 5.7 cm. Histological colon injury induced by DSS-induced colitis was reduced (P<0.05). In serum and DSS-treated colon tissues, mRNA expression levels of IFN-${\gamma}$, IL-6, TNF-${\alpha}$, and IL-12 of the Beopje ginger-treated group were significantly suppressed compared to those of the ginger-treated groups. Expression levels of iNOS and COX-2 of the Beopje ginger-treated group were significantly reduced compared to those of the ginger-treated groups (P<0.05), and BG showed stronger anti-inflammatory effects on colitis. These results indicated that ginger exerted anti-inflammatory effects on DSS-induced colitis in mice, and its effects could be increased through Beopje.

The Chandi Borobudur was likely constructed around 800 AD, during the period of the Sailendra dynasty in central Java, Indonesia. The Chandi Borobudur have 1460 narrative panels of reliefs which are distributed from the hidden foot to the fourth gallery. The 160 panels show various scenes of actions producing the corresponding results according to the Karmavibhanga(分別善惡報應經) text. Blameworthy activities with their purgatorial punishments and praiseworthy activities with their subsequent rewards are both shown. The 120 panels depict the biography of Buddha according to the Lalitavistara (方廣大莊嚴經) text. The 620 panels depict stories from Jatakas (本生譚) and Avadanas (譬喩經). The stories of 560 panels are based on Mahayayana (入法界品, 488 panels) and Bhadrucari (普賢行願讚, 72 panels) of Gandavyuha (華嚴經) text. In this study, among the 120 narrative reliefs which tell the life story of Buddha according to the Lalitavistara text in Chandi Borobudur, the images of Birth of Siddhārtha(誕生), The Great Departure (出家), Attaintment of Enlightenment (成道) and The First Sermon (初轉法輪) have been compared with the images of biography of Buddha showing in Ancient India, Gandhara and South India, and China. From a historical perspective of cultural exchange, Borobudur is very important site because it is located on the south route of transmission of Buddhism from India to South Asia, China, Korea and Japan. Study on the reliefs sculptured on the wall of Chandi Borobudur provide us information to understand the process of spreading and changes in styles of Buddhist arts.

This study was conducted to investigate microbial distribution in the processing steps and to estimate quality index and shelf life of packaged Tofu (soybean curd). Sanitation and safety of Tofu were analysed in aspects of total viable counts (TVCs) and coliforms. Organoleptic deterioration was observed from some packaged Tofu when their TVCs were over $10^6\;CFU/g$. The controlled simply packaged Tofu and sterilized Tofu with TVCs of under $10^5\;CFU/g$ were 32.0% and 86.9% of the total samples, respectively. Also, the controlled simply packaged Tofu and sterilized Tofu with negative coliforms were 12.0% and 83.7% of the total samples, respectively. TVCs and coliforms increased in some processing steps, which include washing and soaking of raw soybeans, and formation and 1st cooling of packaged Tofu. Increases of TVCs and coliforms in the washing and soaking step were due to contamination from the soaking tank and airborne bacteria, whereas increases of TVCs and coliforms in the grinding step were due to contaminations from the grinder, line and reserving tank. TVCs and coliforms increased in the formation and 1st cooling step of packaged Tofu due to contaminations from filter wools, trays, employee's hands, cooling water, formed products and filter wools.

Purpose: We evaluated usefulness of abdominal compressor for stereotactic body radiotherapy (SBRT) with unresectable hepatocellular carcinoma (HCC) patients and hepato-biliary cancer and metastatic liver cancer patients. Materials and Methods: From November 2011 to March 2012, we selected HCC patients who gained reduction of diaphragm movement >1 cm through abdominal compressor (diaphragm control, elekta, sweden) for HT (Hi-Art Tomotherapy, USA). We got planning computed tomography (CT) images and 4 dimensional (4D) images through 4D CT (somatom sensation, siemens, germany). The gross tumor volume (GTV) included a gross tumor and margins considering tumor movement. The planning target volume (PTV) included a 5 to 7 mm safety margin around GTV. We classified patients into two groups according to distance between tumor and organs at risk (OAR, stomach, duodenum, bowel). Patients with the distance more than 1 cm are classified as the 1st group and they received SBRT of 4 or 5 fractions. Patients with the distance less than 1 cm are classified as the 2nd group and they received tomotherapy of 20 fractions. Megavoltage computed tomography (MVCT) were performed 4 or 10 fractions. When we verify a MVCT fusion considering priority to liver than bone-technique. We sent MVCT images to Mim_vista (Mimsoftware, ver .5.4. USA) and we re-delineated stomach, duodenum and bowel to bowel_organ and delineated liver. First, we analyzed MVCT images to check the setup variation. Second we compared dose difference between tumor and OAR based on adaptive dose through adaptive planning station and Mim_vista. Results: Average setup variation from MVCT was $-0.66{\pm}1.53$ mm (left-right) $0.39{\pm}4.17$ mm (superior-inferior), $0.71{\pm}1.74$ mm (anterior-posterior), $-0.18{\pm}0.30$ degrees (roll). 1st group ($d{\geq}1$) and 2nd group (d<1) were similar to setup variation. 1st group ($d{\geq}1$) of $V_{diff3%}$ (volume of 3% difference of dose) of GTV through adaptive planing station was $0.78{\pm}0.05%$, PTV was $9.97{\pm}3.62%$, $V_{diff5%}$ was GTV 0.0%, PTV was $2.9{\pm}0.95%$, maximum dose difference rate of bowel_organ was $-6.85{\pm}1.11%$. 2nd Group (d<1) GTV of $V_{diff3%}$ was $1.62{\pm}0.55%$, PTV was $8.61{\pm}2.01%$, $V_{diff5%}$ of GTV was 0.0%, PTV was $5.33{\pm}2.32%$, maximum dose difference rate of bowel_organ was $28.33{\pm}24.41%$. Conclusion: Despite we saw diaphragm movement more than 5 mm with flouroscopy after use an abdominal compressor, average setup_variation from MVCT was less than 5 mm. Therefore, we could estimate the range of setup_error within a 5 mm. Target's dose difference rate of 1st group ($d{\geq}1$) and 2nd group (d<1) were similar, while 1st group ($d{\geq}1$) and 2nd group (d<1)'s bowel_organ's maximum dose difference rate's maximum difference was more than 35%, 1st group ($d{\geq}1$)'s bowel_organ's maximum dose difference rate was smaller than 2nd group (d<1). When applicating SBRT to HCC, abdominal compressor is useful to control diaphragm movement in selected patients with more than 1 cm bowel_organ distance.

A Lactobacillus sp. has been isolated from infant feces and characterized according to its physiological properties and identified as Lactobacillus acidophilus KLA1012. A gene coding surface layer protein (SLP) has been cloned and the sequence has been determined. The nucleotide sequence of slpA was 1,338 bp in size and was identical to that of L. acidophilus ATCC 4356 (100%). Amino acid sequence of SLP-A was deduced from the nucleotide sequence and it had signal sequence at N-terminal, consisting of positively charged amino acid mainly lysine. slpA was cloned and heterologously expressed in E. coli M15 and the 45.2 kDa surface-layer protein band was examined by SDS-PAGE and confirmed by Western blotting using polyclonal antibody against L. acidophilus KLA 1012 SLP-A protein.

In the present study, we investigated the anti-proliferation activity of Citrus grandis Osbeck peel (CGP) in HL60 (human promyelocytic leukemia) cells. It was found that 80% ethanol extract of CGP could inhibit the cell growth in a dose-dependent manner ($250{\sim}1,000{\mu}g/mL$), which was associated with morphological changes and apoptotic cell death such as depolarized mitochondrial membrane, formation of apoptotic bodies and increased populations of apoptotic sub-G1 phase. The results indicate that CGP extract inhibits the growth of HL60 cancer cells by the induction of apoptosis, which may be mediated by its ability to change the Bcl family proteins and increase the activation of caspase-3 and PARP. Therefore, it is suggested that CGP has the potential to provide a remarkable natural defense against the proliferation of HL60 cells.

At Otani University in Kyoto, Japan, there is a rubbed copy of Tripitaka Koreana, presumably printed in 1381. According to the postscript of the copy, written by Saek Lee himself, the rubbed copy was made at Haeinsa temple in 1381 and was kept at Sinluksa temple in Yeuju. The copy was delivered as a gift to Japan in 1414 and now is kept at the Library of Otani University. Although an approximate summary of the content of the copy was reported in the early 2000s after a basic survey, details of the copy, including the concrete format and packaging paper, are not known yet. In this paper a detailed survey of the copy is conducted on the 109 pages. The copy is divided into two parts: the wrapping and the inner pages. The wrapping paper is divided into yellow and brown colors depending on the material of the paper. The yellow colorwrapping paper was possibly made in 1381 at the time of the rubbed printing, and the brown wrapping paper was repaired after being moved to Japan. Using funds collected in February 1380, the copy of Gyeong(經), Yul(律), and Ron(論) chapters was printed in April 1381. Binding of the copy was completed in September, and the wrapping paper with the title in gold was made in October 1380. The box for keeping Buddhist scriptures was manufactured in November 1380. The copy was moved to Sinluksa temple in April 1382 and delivered to Japan in 1414. At Otani University, the copy is stored in separate rectangular boxes 32.1×25.3cm in size with a height of 23.6cm. The rectangular plate on the four sides is red in external color but black colorinside. The box for keeping Buddhist scriptures was probably made in 1381, but a partial repair was made later. Because of the difficulty of executing a detailed survey of the box for Buddhist scriptures, it is hard to find out its nation and period of production. We look forward to studying the copy as well as the box for Buddhist scriptures in future.

In this study, we analyzed 24 pieces ($4{\times}3{\times}2$) of pork jerky produced using raw meat and we then randomly assigned the hind leg meat to a treatment group. In addition, the effects of storage according to aerobic plate counts and sensory evaluation on pork jerky were examined. Form the results, We found that volatile basic nitrogen (VBN) content and aerobic plate counts of pork jerky gradually increased with increased storage time, ; moreover, there was a significant difference between the treatment groups and the control group (p<0.01). However, the counts did not increase as significantly in the ginseng powder group (B), as compared to the ginger powder group (A) (p<0.05). The sensory evaluation of pork jerky peaked during the second week of storage in all treatment groups, after which these characteristics gradually decreased (p<0.05). In addition, these characteristics were generally higher in the control group, compared to the treatment groups. When comparing the ginseng powder addition group (B) and ginger powder-addition group (A), only color was significantly higher in the ginger powder group. Based on this study as well as previous studies, storage of pork jerky significantly affects the sensory evaluation of raw pork. Ginger powder may have a more beneficial effect than other treatments on the sensory evaluation. Additionally, in all treatment groups, sensory characteristics were significantly higher in the ginger treated groups than in those of the ginseng-treated groups.
