The results of wet noodles added with 0, 1, 3, 5, and 7% freeze-dried maesangi powder demonstrate that the addition of maesangi powder up to 5% was desirable formation of noodles. The moisture contents of wet noodle 35.48~36.42%. As the added amount of maesangi powder increased, weight, volume, water absorption, and turbidity the wet noodle soup after cooking increased. Measurement of color changes between before and after cooking the wet noodles found that as the added amount of maesangi powder increased, the lightness and yellowness increased. Measurement of texture after boiling found that, hardness, chewiness and gumminess tended to increase as the amount of added maesangi powder increased whereas, springiness and cohesiveness were significantly different between the different samples. The results of the sensory evaluation showed that the 3%-added group was the best for color, flavor, and taste while the control groups had the best texture. For overall acceptability, the 3%-added group showed found the highest preference level. Measurement of the changes in total viable cells during storage at $5^{\circ}C$ for 18 days found that 6-days was the optimal storage period for the noodles from the control groups and added groups. As the storing period increased, the maesangi powder added groups showed slower propagation speed for viable cells compared to the control groups.

This study investigated the free sugar and free amino acids considered as the taste component in Korean Gochujang. Our goal was to search and develop the Korean traditional Gochujang taste, and to monitor the current status and characteristics of the Gochujang. For the analysis of Gochujang, it is purchased from small farms as well as major food company producing Gochujang. In the case of commercial Gochujang(COM), glucose and maltose were major free sugar, and the ratio of distribution and total amount showed very similar pattern. However, the results of the traditional Gochujang(TG) showed significant differences for each sample even they had glucose and maltose as predominant sugar. The content of glucose, maltose, fructose was reduced in order. The other hand, sucrose, rhamnose were not detected or were detected trace amounts in some samples. Even the characteristics were found at each region, it was no noticeable difference, but each sample was greater variation. Total of 17 amino acids were found from COM and the major amino acids were Pro, Glu, Asp, but His, Met were generally detected in small amounts. In the TG, they mainly contained Glu, Asp, Pro as the dominant component in addition to the Arg, Ala, Cys, respectively. TG had higher amino acid content and fairly various distribution compared to COM. It could suggest the possibility of the development for different traditional tastes because each TG had diverse characteristic taste than COM.

BACKGROUND: 'Shiranuhi' mandarin is one of the popular citrus cultivars in Jeju Island, Korea. However, the emergence of scion roots since the past few years has altered its flowering, fruiting, and quality. Girdling of branches is one of the methods of increasing flowering in citrus trees. METHODS AND RESULTS: This experiment was conducted to determine the effect of girdling on the flowering and yields of scion rooted 'Shiranuhi' mandarin hybrid. We selected normal trees without scion roots as controls. The trees with scion roots were divided into two groups: trees without girdling and with girdling on main branches. Each group contained five replications and the experiment was conducted in Gosan and Harye of Jeju Island. The scion rooted trees revealed severely decreased flowering and low flowering/leaf ratios; however, the leaf/fruit ratio significantly increased. But, girdling on main branches significantly increased flowering and the flowering/leaf ratio. In the scion rooted trees, yields dropped due to poor flowering; however, girdling of branches efficiently improved the yields of the trees. Fruit quality, fruit size, and fruit weight of scion rooted trees were low in comparison with the control, whereas girdling of the branches improved flowering and the fruit weight to some extent. No significant difference in soluble solid contents was observed. CONCLUSION: Girdling is an effective method to induce flowering of the scion rooted 'Shiranuhi' mandarin trees. In addition, yields of scion rooted trees were improved.

An 8-year-old boy presented with abdominal pain and poor oral intake for two months. Serum amylase and lipase levels were elevated. CT of the abdomen and chest X-ray showed two pseudocysts at the pancreatic uncinate process, pancreatitis with a parenchymal defect, a large amount of ascites, and a right pleural effusion. MR cholangiography and endoscopic retrograde cholangiopanreaticography revealed a pancreatic duct disruption. The patient was successfully treated with a chest tube placement and percutaneous drainage. After surgery, his general condition improved; the serum level of amylase normalized and the pleural effusion resolved. Pancreatic injuries are rare in pediatric blunt trauma; however, diagnostic difficulty is common with isolated blunt trauma. Therefore, a high index of suspicion should follow such an injury. We report the case of an 8-year-old boy with pancreas transection, ductal disruption, ascites, and pleural effusion who was successfully treated.

Objective : To estimate the burden of diseases in Korea especially caused by major cancers using the YLL(years of life lost due to premature death) measurement. Methods : First, we determined the parameters: such as age-specific standard life expectancy, age on death, sex, cause of death by analyzing the national death certificate data and life table collected during 1996 provided by the National Statistical Office. Secondly, we estimated the age group-specific YLL by employing standard expected years of life lost(SEYLL). Thirdly, final burden of disease due to premature death was estimated by using YLLs measurement which developed by global burden of disease study group. Results : The burden of premature death by cancer for male was attributed mainly to liver cancer(514.5 person-year), stomach cancer(436.4 person-year), and lung cancer(367.7 person-year). Each of these cancers was responsible for the loss of over 100 person-year based on our YLL measurement. The burden of premature death by cancer for female was attributed mainly to liver cancer(135.1 person-year), stomach cancer(252.1 person-year), and lung cancer(121.8 person-year). Each of these cancers was responsible for the loss of over 100 person year based on our YLL measurement. Conclusion : We found the YLL method employed in this study was appropriate to quantify the burden of premature death. Thereby, it would provide a rational bases to plan a national health policy regarding premature death caused by cancer.

HAE series (HAE 01 - 06), are the mixtures of medicinal plants; Lonicerae Folium et Caulis (Lonicera japonica), Scutellariae Radix (Scutellaria baicalensis), Adenophorae Radix (Adenophora triphylla var. japonica), Polygonati Oddorati Rhizoma (Polygonatum odoratum var. pluriflorum), Platycodi Radix (Platycodon grandiflorum), Liriopis seu Ophiopogonis Tuber (Liriope platyphylla). HAE 06 showed the significant antitussive effect in HAE series. HAE 04, 05, and 06 increased the effect of expectorant measured by secretion of phenol red in rats. All tested HAE series were observed to have the anti-oxidant activity determined by the scavenging activity. HAE 01, 03 and 06 were significantly reduced the production of nitric oxide (NO) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) increased by LPS. HAE 06 was selected based on the results and done further experiments. HAE 06 inhibited the number of coughing induced by citric acid in dose dependent manner. HAE 06 effectively increased the effect of expectorant. HAE 06 exhibited anti-inflammatory effects by inhibiting the production of NO and TNF-${\alpha}$. In addition, HAE 06 significantly suppressed inducible Cyclooxygenase-2 (COX-2). Especially HAE 06 has the highest effect in alleviating the respiratory symptoms. Moreover, the enhancement antioxidant activity and reduction inflammation partly were attributed to it. HAE 06 may become the promising candidate for the treatment of respiratory symptom in the future.

To investigate the tendency of $Li^+$ exchange from polar organic solvents, $Li^+$-ion exchange into zeolite Y (Si/Al = 1.56) was attempted by undried methanol (crystal 1) and formamide (crystal 2) solvent. Two single crystals of Na-Y were treated with 0.1 M LiNO3 in each of the two solvents at 323 K, followed by vacuum dehydration at 723 K. Their structures were determined by single-crystal synchrotron X-ray diffraction techniques in the cubic space group $Fd{\bar{3}}m$, at 100(1) K. In both structures, $Li^+$ for $Na^+$ ions filled preferentially sites I' and II. The remaining $Na^+$ ions occupied sites I', II, and III' in both structures, in additional to above sites, and $Na^+$ ions occupied site I in crystal 2. While the 68 % exchange of $Li^+$ for $Na^+$ was achieved from undried methanol, only 40 % exchange was observed from undried formamide, indicating that the undried methanol was more effective than undried formamide as solvent for $Li^+$ exchange under the conditions employed.

This study analyzed the uncertainty of the forecasted link traffic flow, and estimated of the interval link flow using Korea Transport Data Base (KTDB) to consider those risks into the feasibility study. In the paper, the uncertainty was analyzed according to the stochastic variation of the KTDB origin-destination traffic. It was found that the uncertainty of the entire network traffic forecasts was 15.4% in average,. when the stochastic variation of the KTDB was considered. The results showed that the more congested the roads were, the bigger the uncertainty of forecasted link traffic flow were found. In particular, we estimated the variance of the forecasted traffic flow, and suggested interval estimates of the forecasted traffic flow instead of point estimates which were presented in the common feasibility studies. These results are expected to contribute the quantitative evaluation of uncertain road investment projects and to provide valuable information to the decision makers for the transport investment.

This study was carried out to know the effects of Gwanjul9-bang (hereinafter reffered to GJ9) on the inhibition of arthritis induced by collagen on DBA/1J mouse. For this purpose, GJ9 was orally administered to mouse with arthritis induced by collagen II. Cytotoxicity, hepatotoxicity, arthritis index, value of immunocyte in draining lymph node and paw joint, rheumatoid factor (IgG, IgM) in serum were measured in vivo. The cytotoxicity against hFCs was not measured in any concentration. The hepatotoxicity was low in GJ9 treated group compared with MTX group. The arthritis index was decreased significantly. In total cell counts of DLN and paw joint, the cells in DLN increased significantly while there was significantly decrease in paw joint. In lymph nodes, $CD19^+$, $CD3^+$, $CD4^+$, $CD3^+CD69^+$, $CD8^+$, $CD4^+CD25^+$, $CD3^+CD49b^+$, $CD4^+CD44^+$, $CD3^+CD8^+$ cells increased significantly, $B220^+CD23^+$cells decreased significantly. In joints, $CD3^+$, $CD4^+$, $CD4^+CD25^+$, $CD11b^+Gr-1^+$ cells decreased significantly. The levels of IgG and IgM was significantly decreased compared with control. Anti-collagen II in serum was significantly decreased compared with control. The degree of arthritis induced damage of joint of GJ9 group is slight compared with control group in histopathologic observation (Hematoxylin & Eosin, Masson's Trichrome). Comparison of the results for this study showed that GJ9 had immunomodulatory effects. So we expect that GJ9 should be used as a effective drugs for not only rheumatoid arthritis but also another auto-immune disease. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.
