Hydrogen producing acidogenic microorganisms were self-immobilized using organic-inorganic hybrid polymer within 5 minutes. During the continuous tratment of synthetic wastewater at a hydraulic retention time of 20 hours, at 37$^{\circ}C$, pH 5.0, the self-immobillized granules were maintained in a stirred tank reactor. The black colored granules gradually became milky. Image analysis showed that the mean diameter of the milky colored granules ranged from 1.5 to 20. mm. The maximum bio-gas procuction rate was 380 ml/L/hy and the concentration of H$_2$was around 50%, while no methane was detected. Granular ECP was extracted and its content was measured to elucidate the role of the organic-inorganic hybrid polymer. Further increases of granule concentration are expected to increase the hydrogen production rate.

Cases of incomplete Kawasaki disease (KD), wherein the patient does not fulfill the full diagnostic criteria for KD, are often detected in infants younger than 6 months of age. The clinical manifestations in infants with incomplete KD may resemble other infectious diseases, including meningitis. For this reason, clinicians may have difficulty differentiating incomplete KD from other infectious diseases in this population. Various neurological features are associated with KD, including aseptic meningitis, subdural effusion, facial nerve palsy, cerebral infarction, encephalopathy, and reversible corpus callosum splenial lesions on magnetic resonance imaging. We report a case of a 5-month-old girl with incomplete KD, associated with cerebrospinal fluid pleocytosis and an epidural fluid collection. Echocardiography indicated dilatation of the main coronary arteries. The girl made a complete recovery, with resolution of both the epidural fluid collection and coronary artery aneurysms. In this case, the child is well, and showed normal developmental milestones at the 7-month follow-up.

Recent studies suggest that sphincter of Oddi dysfunction (SOD) is one of the possible causes of unexplained recurrent acute pancreatitis in children. A 14-year-old boy who had suffered from idiopathic recurrent acute pancreatitis was diagnosed with SOD. Abdominal ultrasonography, computerized tomography, and magnetic resonance cholangiopancreatography revealed no evidence of stone, tumor, or pancreatic ductal anomaly. Endoscopic retrograde cholangiopancreatography (ERCP) and sphincter of Oddi manometry (SOM) revealed elevated basal pressure and tachyoddia consistent with SOD. Hence, an endoscopic pancreatic sphincterotomy was performed. We report a case of recurrent acute pancreatitis associated with SOD in a child. ERCP and SOM may be considered in patients with multiple unexplained attacks of pancreatic pain and negative abdominal imaging.

Physiochemical and sensory properties of muskmelon pickles were investigated under salting condition using deep seawater salt, sun-dried salt and purified salt. The changes of weight, shrinkage rate salinity and pH of muskmelon during salting time were almost nothing shown. Turbidity of pickle juice was the highest in salt solution using sun-dried salt and was almost nothing shown in deep seawater salt and purified salt. Solid content of pickle juice was higher in pickle juice using sun-dried salt than deep seawater salt and purified salt. The calcium content of muskmelon salted by deep seawater salt and sun-dried salt were increased to 4.3 times and 3.7 times, respectively. Hardness became a little higher on muskmelon using deed seawater salt ann sun dried salt than purified salt. In organoleptic result, color, flavor, taste, texture and overall palatability of muskmelon salted by deep seawater salt became higher in other salt solution (sun-friend salt and purified salt).

The effects of dietary fiber isolated from ascidian (Halocynthia roretzi) tunic on the changes of weight, total gut transit time, serum cholesterol and glucose level were investigated in rats. Twenty four male rats were divided into 4 groups and were fed a control diet and three fiber supplemented diets with 5,10 and 20% of ascidian insoluble cellulose for 4 weeks, respectively. Food intake was not affected by the supplemented diet of ascidian cellulose but the body weight gain and food efficiency ratio were reduced in proportion to a feeding amount of ascidian cellulose. The fecal output and fecal water content were increased, gut transit time was shortened, and length of gut was elongated in all dietary fiber groups. Serum cholesterol, LDL-cholesterol, neutral lipid, phospho-lipid and serum glucose concentrations were lowered and HDL-cholesterol was increased in rats fed the ascidian insoluble cellulose diet in proportion to a feeding amount of ascidian cellulose.

Benign prostatic hyperplasia (BPH) is one of the common diseases in elderly men. Recently, the old-aged population has increased, with the interest in the clinical importance of BPH ever growing. This study is designed to investigate the effects of KH-305 on BPH induced rat. The herb formulation KH-305 is consisted of Rubus coreanus, Cornus officinalis and Cuscuta chinensis. An experimental prostatic hyperplasia was induced in male rats by the administration of testosterone propionate, 3 mg/kg SC, for 2 months. The rats were divided into 3 experimental groups: the control, BPH-induced, oral KH-305 ingestion group. After 2 months, the prostates were removed, and analyzed for their prostatic weight and histological examination. The prostate weights were measured in each group, and found to be 820${\pm}$38mg, 3140${\pm}$26mg, 1880${\pm}$21mg in the control, BPH-induced, and oral KH-305 ingestion group, respectively. The BPH induced group showed statistically significant increases in their prostatic weights compared with control group(p<0.05) but oral KH-305 ingestion group showed more significant decreases than BPH-induced group statically(p<0.05). Histologically injected testosterone lead to prostatic hyperplasia in rats, but oral KH-305 ingestion decreased this change. These results suggest that KH-305 may be effective in treatment of BPH, and complementary medicine of BPH.

In the soil treated with irrigation control and gypsum, different species of rice plants, Jin-heung, Aggibare, Tong-il, Mil-yang 23, Noindo, Yugnong-chat, were grown. The content of cadmium, copper and zinc in the brown rice was investigated. Results obtained are as follows : 1) Cadmium Content of brown rice was remarkably reduced under the condition to maintain the reduction than oxidation after ear forming stage, and also the application of gypsum was additional effects to reduce cadmium uptake under reduction condition. Zinc and copper contents in the brown rice was similar to calcium reducing, but their effects of reduction were appeared less than cadmium. 2) The reduced tendency of cadmium uptake under the reduction condition was in the order of Tong-il>Mil-yang23>Aggibare>Yugnong-chal>Noindo>Jin-heung. 3) In the oxidzing condition, Jin-heung uptaked cadmium, copper and zinc more than any other species.

Recent growth of the geospatial information on the Web has made it possible to easily access a wide variety of geospatial information. An integration of different geospatial objects consists of the following three steps; extracting geospatial objects from the maps, converting the coordinate system and discovering pairs of objects that represent the same real-world entity in the two maps. This paper deals mainly with the third step to correspond conjugate objects and four matching types and criteria is presented. The techniques designed and developed can be utilized to efficiently integrate distributed heterogeneous spatial databases such as the digital maps and POIs from other data sources. To achieve the goal, we presented four types and criteria for the matching schema. The main contributions of this paper are as follows. A complete process of integrating data from maps on the Web is presented. Then, we show how attributes of the objects can be used in the integration process.

The objective of this study was to compare the textural properties and sensory evaluation of Injulmi, a traditional Korean waxy rice cake, added with 10, 20 and 30% of RS3-type resistant starch. RS3-type resistant starch was prepared from nonwaxy rice(Odaebyeo) starch by autoclaving-cooling cycle. The RS yield of RS3-type resistant starch was 9.10%. By increasing the addition level of RS3-type resistant starch, the hardness and adhesiveness of Injulmi increased as measured by using a rheometer. Hunter color L and a values of Injulmi added with RS3-type resistant starch were increased, but b value was decreased. In case of sensory evaluation, the hardness of Injulmi added with RS3-type resistant starch was higher than that of non-added Injulmi. The overall duality of Injulmi added with RS3-type resistant starch by sensory evaluation was negatively correlated with the hardness measured by rheometer(p＜.0.05).

The effects of soaking time of nonwaxy rice and particle size of rice flour on the properties of nonwaxy rice flour after steeping at room temperature were investigated. Nonwaxy rice was soaked at 20$^{\circ}C$ for 0, 1, 12, or 24hr, dried at room temperature and milled. Nonwaxy rice flours were passed through 45 mesh or 100 mesh sieve, and were compared for the properties depending on the particle size and soaking time. The particles of rice flour were separated into 10$\mu\textrm{m}$∼30$\mu\textrm{m}$ and 40$\mu\textrm{m}$∼80$\mu\textrm{m}$ groups, and the amount of large particle size(40$\mu\textrm{m}$∼80$\mu\textrm{m}$) was greater in the flour sieved through 45 mesh than 100 mesh sieve. The protein and ash contents decreased and amylose contents increased as the soaking time increased. The water-binding capacity increased rapidly up to 1 hr of soaking and increased slowly thereafter. The swelling power and the solubility increased with temperature rising in the range of 65$^{\circ}C$∼95$^{\circ}C$, and these two properties increased rapidly up to 12 hr of soaking. Peak viscosity and breakdown of the pastes prepared with 12 hr-soaked nonwaxy rice flour were higher than those with 1 hr-soaked ones, while the setback and viscosity at 95$^{\circ}C$ of 12 hr-soaked ones were lower than 1hr-soaked ones.
