In this study, we attempted to evaluate the feasibility of a supercritical methanol process for direct production of biodiesel from microalgae. The effects of various factors such as temperature, reaction time, water content and pretreatment on the efficiency of biodiesel conversion were investigated. The conversion efficiency increased with both temperature and extraction/conversion time. The supercritical methanol process produced a fatty acid methyl ester (FAME) yield of around 88% within 20 minutes. The optimal conditions for this process were found to be a microalgae/methanol ratio of around 1:9, a reaction temperature of about 270℃, and a reaction time of approximately 20 minutes. The effect of water content in microalgae samples on the FAME conversion was also evaluated. The supercritical methanol process was not affected by the water content up to 250 wt%. Our experiments demonstrated that the supercritical methanol process is more effective compared with conventional in situ transesterification processes.

The purpose of this study is to estimate the implicit prices and consumers’ preference by attributes on Korean beef cattle ham using choice experiments. Main attributes are the country of origin, non-antibiotic certification, HACCP certification, addition of Korean agricultural products and use of natural colors. The implicit prices of each attribute and level for country of origin are estimated as KRW 919.0 for Korean pork, KRW 2,173. for imported beef and KRW 5,232.9 for Korean cattle beef. The other estimated implicit prices are KRW1,762.9 for non-antibiotic certification, KRW 577.5 for HACCP certification, KRW 57.9 for addition of Korean agricultural products and finally, KRW 572.9 for use of natural colors. This study is expected to contribute to the decision-making process of Korean beef cattle farmers by providing useful quantitative information on attributes and price that are related to consumers’ preference on Korean beef cattle ham.

Gastritis cystica profunda (GCP) is a disease characterized by hyperplastic and significant extension of cystic dilatation of the gastric mucous glands, which results in a cystic lesion in gastric submucosa. It often occurs on the part of gastroenterostomy, but can be found in the stomach without any previous surgery. GCP has variable gross finding including solitary polyps, diffuse ones, submucosal tumors, and rare giant gastric mucosal fold. It is difficult to tell GCP from a cancerous lesion by gross finding that the disease demands a necessary tissue biopsy, though GCP is commonly showed as a benign in the progress. We report a case of GCP in polypoid types diagnosed by endoscopic polypectomy.

Despite enormous progress in current chemotherapeutic approaches for cancer, there is no advances of prognosis in malignant tumor of head and neck. Especially the prognosis in tongue cancer in which vessels are well developed is bad. Therefore, it is very important to distinguish the patient with infiltrating tumor and to find tumor marker which can play a key role in effective strategy for cancer treatment. Because there is little report about CD44 as prognostic marker in tongue cancer, this study was performed to investigate the alteration of CD44 expression in tumor specimens from eleven patients with tongue cancers before and after chemotherapy. In this study, CD44 was expressed strongly in spinous layer of specimen before chemotherapy and the expression of CD44 decreased significantly after chemotherapy, suggesting that the expression of CD44 is related with metastasis of tongue cancer. Taking above, the alteration of CD44 expression in tongue cancer tissue by chemotherapy suggests that CD44 are potentially expected to use in tongue cancer as prognostic factors.

Gastric angiodysplasia is vascular ectasia in mucosa and submucosa of the gastric wall. It is an uncommon cause of upper gastrointesinal hemorrhage that may occur in the stomach or duodenum. There are many kinds of endoscopic treatments, such as argon plasma coagulation, electrocoagulation, heat probe, and submucosal injection of hypertonic saline mixed with epinephrine for gastric angiodysplasia. However, these treatment methods are associated with high rate of rebleeding. In order to avoid the recurrence, endoscopic band ligation has recently been used as an alternative method for endoscopic treatment of gastric angiodysplasia. We encountered a case of gastric angiodysplasia that presented with overt bleeding and anemia, and was successfully treated with endoscopic band ligation.

To evaluate the safety and efficacy of Pd withdrawal followed by recombinant alpha- Interferon 2b therapy. Nine patients were given a single daily subcutaneous injection of ^α-Interferon at a dose of 3 x 10 exp(6) units/day for first weeks and thrice weekly for next 15 weeks (maintenance) after pd tappered over 6 weeks. To evaluate the efficacy of therapy, we measured serum aminotransferase activities monthly during and after therapy, and also measured serm HBsAg, HBeAg and DNA probe before and after therapy. To evaluate the safety of therapy, all patients checked peripheral blood WBC, Hemoglobin, Platelet, BUN and Creatinine. The results were as follows : 1. In control group, the normalization of s-AST & ALT level, negative seroconversion of DNA probe & HBeAg were observed in 1/12(8%) & 7/10(17%), 0/10(0%) & 0/12(0%) at 6 months later, and maintained response in 1/11(9%) & 1/11(9%), 2/9(22%) & 2/11(18%) until 1 years later. 2. In treatment group, Serum AST and ALT returned to normal in 8/9 & 8/9 cases (89%) after 1 montns Tx. (mean serum AST : 33±8, ALT : 34±12 IU/ml) and maintained to normal response in 5/9(56%) & 6/9 cases(67%)after 6 months Tx. (mean s-AST : 55±43, ALT : 66±84 IU/ml), 3/9(33%) & 4/9 cases(44%) after 1 years Tx. It was statistically significant reponse except s-AST of after 1 years Tx. 3. In treatment group, s- HBeAg returned to normal in 3/9 cases(33%) after 1 months Tx., and maintained to normal response in 1/7 & 1/4 cases among follow up patients in after 6 & 12 months Tx. Serm DNA probe level were observed significantly negative seroconversion in 8/9 cases(89%) after 1 months Tx. (p<0.003), and maintained to negative response in 2/6 & 1/3 cases after 6 & 12 months Tx. 4. Serum AST, ALT, HBeAg and DNA probe were not significantly correlated with therapeutic response in relation to histologic diagnosis. 5. Fever and myalgia were noted in 9(100%) & 6(67%) cases. Headache, mild hair loss, anorexia, nausea, facial flushing & diarrhea were noted in few cases. Peripheral WBC(3cases) & platelet counts(3cases) were decreased transiently. This study shows that Pd withdrawal followed by recombinant alpha Interferon 2b therapy may be safe and effective in decrease the level of s-DNA probe, transaminase activity, loss of HBeAg and less adverse effect of clinical and hematologic examinations in patients with CAH type B. But it was necessary for study with large number of patients, more prolonged follow up duration and more strict control study.

A process was studied for separation and concentration of boron from steelmaking dust by the selective leaching with sodium hydroxide and adsorption and desorption with chelating resin. The major constituents in this steelmaking dust are iron, zinc, sodium and silicon. The steelmaking dusts were contented of rare metals such as boron, gallium and vanadium. Of the boron contained in the dust, 72% leached with 3.0㏖/1 sodium hydroxide solution. To remove the impurity metals, they were precipitated as their hydroxides by adjusting the solution pH being 10. The selective concentration of boron was done using a chelating resin column with a functional group of glutamine type, and the eluate containing 4.7g/1 of boron was obtained.
