The monthly mean daily global solar radiation and sunshine duration, have been employed in this study to develop correlation model for Daegwallyeong during 2011. The corresponding monthly value of extraterrestrial solar radiation and possible duration of sunshine are calculated for Daegwallyeong meteorological data. Forecasting performance parameters such as coefficient of determination (R2), mean bias error (MBE) and root mean square error (RMSE) are presented as analyzed for the model. The model with multi-linear regression has the highest R2 value of 0.95 and average MBE and RMSE values of −0.11 MJ/m2day and 1.63 MJ/m2day, respectively. The model exhibited negative MBE which shows that the model resulted in underestimation of the global solar radiation relative to the meteorological measured value. The equation could be employed in the estimation of solar radiation at Daegwallyeong, other locations with similar meteorological characteristics.

We give pressure stimulation into organic thin films and then manufacture a device under the accumulation condition that the state surface pressure is 30[mN/m]. In processing of a device manufacture, we can see the process is good from the change of a surface pressure for organic thin films and transfer ratio of area per molecule. The structure of manufactured device is Au/arachidic acid/Al; the number of accumulated layers is 17, 19 and 21. Also, we then examined of the MIM device by means of Ⅰ-Ⅴ. Then Ⅰ-Ⅴcharacteristic of the device is measured from 0 to +2[V]. In the cyclicvoltammetry, stable up to 0.9[V] vs. Ag/AgCl. The insulation property of a thin film Is better as the distance between electrodes is larger.

Recent experimental studies and clinical cases have suggested that grafting tissue from the adrenal medulla into the brain may alleviate the symptoms of Parkinson's disease. Autologous adrenal medullary grafts into the striatum was performed stereotactically in two patients with Parkinson's disease. Both patients were bedridden preoperatively, but 4 months after the surgery both became ambulatory and one was even capable of returning to his job. Even though the number of cases was small⑵ and the follow-up period was short, this study shows that adrenal medullary transplantation into the striatum may have some beneficial effects in patient with Parkinson's disease. Further experimental and clinical trials are necessary to see whether this procedure will be a recommendable surgical treatment for patients suffering from Parkinson's disease.

Actinomycosis is an uncommon chronic suppurative disease characterized by multiple abscess, draining sinuses, abundant granulation, and dense fibrous tissue, caused by the actinomyces organisms. It occurs in three major sites: cervicofacial, abdominal, and thoracic. The abdomen is the second most common involved site in previous studies, and there are three ways this organism can affect the gastrointestinal tract: through a blood-borne infection, by swallowing, or by proliferation at a more distal intestinal area. Abdominal actinomycosis is an unusual disease but remains an important differential diagnosis in patients with abdominal mass. Obtaining the diagnosis is difficult and rarely made preoperatively, but provide the key to its management. Medical therapy is effetive in eradicating the disease; however, because of the large amount of reactive fibrosis formed by the infection, it requires long-term therapy. Surgical treatment may be essential in many cases, primarily when malignancy cannot be excluded or if extensive necrotic tissue exists. There are a few description for actinomycosis involving omentum. We report a case of patient with omental actinomycosis, suspected to have a malignancy requiring an exploratory laparotomy with resection.

Background/Aims: Retroperitoneal fibrosis is a fibrosing disease process which frequently develops ureteral obstruction. Malignant retroperitoneal fibrosis has been reported that various types of cancer including cancer of the breast, stomach, prostate, lung, cervix, uteri, colon, pancreas, ovary, and even Hodgkin's disease. While the pathogenesis remains obscure, small foci of metastatic neoplasm in the retroperitoneal space can elicit a desmoplastic reaction in secondary form to malignancy. Methods: Recently we experienced 7 cases of retroperitoneal fibrosis with advanced gastric cancer. So, we report 7 cases of retroperitoneal fibrosis with clinical and radiologic characteristics. Results: The most common signs and symptoms were related irreversible renal dysfunction. The urologic finding noted medial deviation of the involved ureters and hydronephrosis Conclusions: Clinical manifestations are abdominal pain, back pain, hydronephrosis, and uremia. When sudden back pain and hydronephrosis develop in advanced malignancy, physicians should be considerd for retroperitoneal fibrosis.

Background : Bleeding after endoscopic procedure of the stomach carries an increased risk of morbidity and mortality. In case of oozing hemorrhage, not in active hemorrhage, powdered sodium alginate may play a role in control of bleeding with convenience. Therefore, we evaluated the clinical effect and efficacy of sodium alginate powder in upper G-Ⅰ bleeding. Methods : Forty-five patients who had upper G-Ⅰ bleeding after endoscopic procedure were enrolled in this study. Twenty-five patients of them were managed by the application of powder preparation of Sodium alginate(ALTO). The others were observed without treatment. The next day, we performed endoscopy in all patients to ascertain the hemostasis. Results : Of 25 patients managed with Sodium alginate, only two patients(8%) had bleeding (hemostatic rate : 92%), On the other hand, of 20 patients who did not receive any treatment, 3 patient(15%) had bleeding (hemostatic rate : 85%). There was no statistical difference between the two groups(p>0.05). Using other endoscopic procedure, We successfully treated the patient who continued to bleed. Conclusion : We evaluated the effect of the spary of sodium alginate on oozing hemorrhage. Although there was no statistical significance in our study, it seems that the spray of sodium alginate may be a useful method for the prevention of bleeding after endoscopic procedure.

Background/Aim: It is difficult to dignosis of Borrmann type 4 gastric cancer at the early stage, because of its special morphology. Most of the cases have been detected at the advanced stage with poor survival rate. We reviewed patients with advanced gastric cancer, to define clinicopathologic characteristics of Borrmann type 4 gastric cancer comparing other types of gastric cancer. Methods: 1033 patients with advanced gastric cancer were divided into two groups, consisting of 50 patients with Borrmann type 4 gastric cancer, and the remaining 983 patients with all other types of gastric cancer, which were then compared clinicopatologically. Results: The proportion of Borrmann type 4 gastric cancer to advanced gastric cancer was 4.48%(50/1,033). The patients with Borrmann type 4 gastric cancer to advanced gastric cancer was 4.48%(50/1,033). The patients with Borrmann type 4 gastric cancer were composed 20 males and 30 males and revealed the highest frequency 3rd decade (24.0%) in age (range 26-78). In giant folds group (n=27), the number of poorly differentiated cell type, lymph node metastasis, peritoneal seeding were 20 (74.1%), 17 (63,0%), 12 (44.4%). In non-giant folds group (n=23), the number of poorly differentiated type, lymph node metastasis, peritoneal seeding were 17 (73.9%), 15 (65.2%), 6 (26.1%). Rate of tumor invasion in serosa and beyound serosa was 88.9% in giant fold group, 63.0% in non-giant fold group. Surgery was performed in only 32% as a modality of treatment (vs. 82.5%). Characteristics findings of Borrmann type 4 gastric cancer in EUS showed a thickening of the third (submucosa) and fourth (muscularis propria) layers in 72% of 50 patients, and a well preserved five-layered gastric wall structure in 33 patients. Conclusions: We concluded that Borrmann type 4 gastric cancer was diagnosed more in females, as a more advanced disease, early detection was needed. And endoscopic ultrasonography is useful for diagnosis of Borrmann type 4 gastric cancer in the cases of suspicious results of gastroscopy.

<P><B>Abstract</B></P><P>Although NKT cells have been implicated in diverse immunomodulatory responses, the effector mechanisms underlying the NKT cell‐mediated regulation of pathogenic T helper cells are not well understood. Here, we show that invariant NKT cells inhibited the differentiation of CD4<SUP>+</SUP> T cells into Th17 cells both in vitro and in vivo. The number of IL‐17‐producing CD4<SUP>+</SUP> T cells was reduced following co‐culture with purified NK1.1<SUP>+</SUP>TCR<SUP>+</SUP> cells from WT, but not from CD1d<SUP>−/−</SUP> or Jα18<SUP>−/−</SUP>, mice. Co‐cultured NKT cells from either cytokine‐deficient (IL‐4<SUP>−/−</SUP>, IL‐10<SUP>−/−</SUP>, or IFN‐γ<SUP>−/−</SUP>) or WT mice efficiently inhibited Th17 differentiation. The contact‐dependent mechanisms of NKT cell‐mediated regulation of Th17 differentiation were confirmed using transwell co‐culture experiments. On the contrary, the suppression of Th1 differentiation was dependent on IL‐4 derived from the NKT cells. The in vivo regulatory capacity of NKT cells on Th17 cells was confirmed using an experimental autoimmune uveitis model induced with human IRBP<SUB>1–20</SUB> (IRBP, interphotoreceptor retinoid‐binding protein) peptide. NKT cell‐deficient mice (CD1d<SUP>−/−</SUP> or Jα18<SUP>−/−</SUP>) demonstrated an increased disease severity, which was reversed by the transfer of WT or cytokine‐deficient (IL‐4<SUP>−/−</SUP>, IL‐10<SUP>−/−</SUP>, or IFN‐γ<SUP>−/−</SUP>) NKT cells. Our results indicate that invariant NKT cells inhibited autoimmune uveitis predominantly through the cytokine‐independent inhibition of Th17 differentiation.</P>
