<P>The surface albedo is an essential climate variable that is considered in many applications used for predicting climate and understanding the mechanisms of climate change. In this study, surface albedo was estimated using a bidirectional reflectance distribution function model based on Communication, Ocean and Meteorological Satellite/Meteorological Imager data. Geostationary orbiting satellite data are suitable for a level 2 product like albedo, which requires a synthetic process to estimate. The authors modified established methods to consider the geometry of the solar-surface-sensor of COMS/MI. Of note, the viewing zenith angle term was removed from the kernel integration used for estimating spectral albedo. Finally, the spectral (narrow) albedo was converted into the broadband albedo with shortwave length (approximately 0.3-2.5 m). This study determined conversion coefficients using only one spectral albedo of visible channel. The estimated albedo had a relatively high correlation with Satellite Pour l'Observation de la Terre/Vegetation and low unweighted error values specific for land types or times. The validation results show that estimated albedo has a root mean square error of 0.0134 at Jeju flux site that indicates accuracy similar to that of other satellite-based products.</P>

Lim, Bong-Suk,Chang, Ung-Kyu,Youn, Sang-Min The Korean Neurosurgical Society 2009 Journal of Korean neurosurgical society Vol.45 No.6

Objective : Percutaneous vertebroplasty (VP) can provide immediate stabilization in pathologic fractures of spinal tumors. However, long term follow-up data in cases of pathologic fractures are lacking. The authors report follow-up results of VP in 185 pathologic fractures of 102 spinal tumor patients. Methods : Percutaneous VP was performed at 185 vertebral bodies of 102 patients from 2001 to 2007. Retrospective analysis was done with medical records and radiological data. The change of visual analogue score (VAS), vertebral body (VB) height and kyphotic angle were measured preoperatively and on postoperative one day and at 3, 6, and 12 months. Results : The patients were composed of metastatic spine tumors (81%) and multiple myeloma (19%). Involved spinal segments were between T6 and L5. Mean follow-up period was 12.2 months. VAS for back pain was 8.24 preoperatively, 3.59 (postoperative one day), 4.08 (three months) and 5.22 (one year). VB compression ratio changed from 21.33% preoperatively to 13.82% (postoperative one day), 14.36% (three month), and 16.04% (one year). Kyphotic angle changed from $15.35^{\circ}$ preoperatively to $12.03^{\circ}$ (postoperative one day), $13.64^{\circ}$ (three month), and $15.61^{\circ}$ (one year). Conclusion : Immediate pain relief was definite after VP in pathologic compression fracture of osteolytic spinal disease. Although VAS was slightly increased on one year follow-up, VP effect was maintained without significant change. These results indicate that VP could be a safe and effective procedure as a palliative treatment of the spinal tumor patients.

Objects : Recent studies of psychosocial adjustment after hospitalization have found that the combination of maintenance antipsychotic drug treatment and psychosocial treatment including psychoeducational program are highly predictive of social rehabilitation and reduction of subsequent relapse. Two groups of patients with refractory chronic schizophrenia were preliminarily compared to determine the effect of a psychosocial treatment program on the quality of life in refractory chronic schizophrenics in an open comparative trial. Methods : One group(N=11) was assigned to approximately six months of the psychosocial treatment program(including psychoeducation program and activity program such as interpersonal relationship program, social skill training, self management program, outings, etc), in a group format, twice a week and a fixed maintenance dosage of clozapine ; while scale(QLS) was used to provide an objective measure of changes in patient's psychosocial functioning and a general assessment of psychopathology was made using the Brief Psychiatric Rating Scale(BPRS). Results : Both BPRS total positive score and the QLS total score, especially in the intrapsychic foundation factor of the scale showed a statistically significant improvement in the psychosocial treatment group. But there was no significant change in both BPRS and QLS scores over a 6-month period in the non-psychosocial treatment group. A significant negative correlation was found between the negative symptom and changes of QLS total, instrumental role and common object and activities scores respectively after receiving a 6-month of the psychosocial treatment program. Conclusion : These results suggest that a psychosocial treatment program including the integration of psychoeducation and a skill training oriented activity program serve as an outpatient treatment modality to improve the quality of the life in refractory chronic schizophrenia. To further clarify the effect of psychosocial treatment in chronic schizophrenia, a randomized trial should be done.

N/A Background/Aitns: It has been reported frequently that clinical features of gallstone diseases in Koreans were different from those of Occidentals. These differences were thought to be due to inherent racial difference and acquired living habits. The purpose of this study is to evaluate whether the pattern of gallstone disease changes or not in Korea. Methods: We analyzed 5,488 cases of gallstone diseases which were reported in Korea frorn 1966 to 1994. We divided the period into 6 groups: the first period was 1,000 cases reported from 1966 to 1970, the second was 331 cases from 1971 to 1975, the third was 1,000 cases from 1976 to 1980, the fourth was 1,957 cases from 1981 to 1985, the fifth was 1,000 cases from 1986 to 1990, and the sixth was 200 cases from 1991 to 1993. Results: The age group of highest incidence was the fifth and sixth decade. The incidence below the third decade showed a decreasing tendency. In contrast, the incidence above sixth decade showed an increasing tendency. The male to female ratio was 1:1.25 to 1:1.71 and had no periological change. The duration of illness of highest frequency was below 6 months. In the case of duration above 5 years these was a decreasing tendency. The major complaints of biliary stone were right upper quadrant pain and tenderness. Nausea, vomiting, jaundice, and radiating pain showed a decreasing tendency. The major laboratory findings were leukocytosis, elevated SGOT and SGPT, elevated alkaline phosphatase, hyperbilirubinemia and hypoalbuminemia. Of these, only hypoalbuminernia had a decreasing tendency. By the second period, the main diagnostic procedures were oral cholecystogram and intravenous cholecysto- graphy. From the fourth period, ultrasonography, ERCP, CT and PTC were been used comrnonly. For the location of gallstone, the gallbladder stone revealed the only increasing tendency, the common bile duct stone had a decreasing tendency, and the intrahepatic duct stone had no periological change. From 1980, the cholesterol stone became the main composition of gallstones. But, there was no periological change between early and late 1980s. Positive bacterial culture rate was 57.0% and the most common microorganism was E. coli. Klebsiella and Enterobacter. Pseudomonas showed an increasing tendency. Of the diseases associated with gallstone, only diabetes had an increasing tendency. The frequency of residual stone had an increasing tendency. Conclusions: The age of peak incidence of gallstone diseases was the fifth and sixth decades and there was a little predominance in females. From 1980, the cholesterol stone becarne the main composition of gallstones. For the location of gallstone, the gallbladder stone showed an increasing tendency and the common bile duct stone revealed a decreasing tendency. These suggested clinical features of gallstone diseases in Koreans are somewhat similar to those of Occidentals. (Korean J Gastroenterol 1997;29:352 - 361)

However, dermoscopic findings are not fully elucidated in the course of β-blocker treatment for IH. Objectives: To investigate changes of dermoscopic findings during the course of β-blocker treatment for IH. Methods: Superficial or mixed-type IH patients treated with topical timolol solution or oral propranolol were enrolled in Pusan National University Hospitals (Busan and Yangsan) from November 2011 to January 2016. Clinical photograph and dermoscopic findings were recorded and assessed at the baseline, 1, 2, 3 and 6 months. Results: Total 115 patients (male: 38 and female: 77 / superficial type: 48 and mixed type: 67 / timolol: 77 and propranolol: 38) were included. Diffuse light erythema tended to be diminished but milky-red area increased gradually during the course of treatment. The patients treated with oral propranolol showed more prominent changes on each dermoscopic findings than those treated with topical timolol (p=0.023 and p=0.018, respectively). But, other findings like red-globular vessels, red-dot vessels, red-circulated vessels, red-linear vessels did not show significant changes. Conclusion: Dissolution of diffuse light erythema and increase of milky-red area were significant dermoscopic findings in accordance with clinical improvement after β -blocker therapy for IH.

Jeong, Dong Won,Kim, Young Hoon,Kim, Hui Hyun,Ji, Hye Young,Yoo, Sun Dong,Choi, Won Rack,Lee, Soo Min,Han, Chang-Kyun,Lee, Hye Suk WILEY PUBLISHERS 2007 BIOPHARMACEUTICS AND DRUG DISPOSITION Vol.28 No.2

<P>The pharmacokinetics of oleanolic acid was evaluated in vitro and in vivo. From Caco-2 cell permeation studies, oleanolic acid was a low permeability compound with no directional effects, suggesting a low in vivo absorption mediated by a passive diffusion. Oleanolic acid was metabolically unstable following incubation with rat liver microsomes in the presence of NADPH. After intravenous injection at doses of 0.5, 1 and 2 mg/kg doses, oleanolic acid showed dose-linear pharmacokinetics as evidenced by unaltered CL (28.6–33.0 ml/min/kg), V<SUB>ss</SUB> (437–583 ml/kg), dose-normalized AUC (16.0–17.9 µg min/ml based on 1 mg/kg) and t<SUB>1/2</SUB> (41.9–52.7 min). Following oral administration of oleanolic acid at doses of 10, 25 and 50 mg/kg, T<SUB>max</SUB>, t<SUB>1/2</SUB>, dose-normalized C<SUB>max</SUB> (66–74 ng/ml based on 25 mg/kg) and dose-normalized AUC (5.4–5.9 µg min/ml based on 25 mg/kg) were comparable between 25 and 50 mg/kg dose, but the plasma concentrations at 10 mg/kg dose were not measurable as they were below the limit of quantitation (2 ng/ml). The absolute oral bioavailability was 0.7% for oral doses of 25 and 50 mg/kg. The extent of urinary excretion was minimal for both i.v. and oral doses. The very low oral bioavailability of oleanolic acid could be due to a poor absorption and extensive metabolic clearance. Copyright © 2007 John Wiley & Sons, Ltd.</P>

This study was conducted to investigate the developmental ability of interspecies cloned embryos after nuclear transfer of goat fetal fibroblast cells into porcien oocytes. Recipient porcine and goat oocytes were obtained from slaughterhouse and matured in vitro according to established protocols. Enucleation was accomplished by aspirating the first polar body and cytoplasm and a single donor cell was individually microinjected into vitelline space of the enucleated oocyte. The reconstructed oocytes were electrically fused with 0.3M mannitol fusion medium. After electro-fusion, interspecies reconstituted embryos were cultured in PZM-3 for 7 days. In porcine interspecies nuclear transfer with goat fetal fibroblast cells, the cleavage rate of reconstituted embryos were 58.9% which was no significant different from that in porcine nuclear transfer embryos (67.4%). However, the developmental rate into blastocyst stage was 5.4% in interspecies nuclear transfer which was significantly lower than that in porcine intraspecies nuclear transfer (13.6%). When the developmental ability of porcine interspecies nuclear transfer with goat cells was compared with goat intraspecies nuclear transfer, the cleavage rate of embryos were 59.2% and the developmental rate into morular and blastocyst stage was 13.6% in interspecies nuclear transfer which were significantly lower than those in intraspecies nuclear transfer embryos. This result indicated that porcine interspecies nuclear transfer with goat fetal fibroblast cells showed the developmental potential in vitro with lower cleavage and developmental rate compared with intraspecies nuclear transfer.

This study was conducted to evaluate the response of CIDR-S on estrus synchronization of dairy goats and the effect of artificial insemination on conception rate. Estrus synchronization of sexually matured Saanen goats was induced with insertion of CIDR-S into vagina for 15 days and injection of 500 IU PMSG before removal of CIDR-S. Artificial insemination was conducted using liquid or frozen semen by intra-cervical insemination with synchronized does. Estrus synchronization was 90% using CIDR-S insertion for 15 days. Conception rate of inseminated does was 20% - 25%, while that of natural mated does was 100%. These results suggested that synchronization of dairy goats can be successfully induced and artificial insemination method has to be improved for the practical use in dairy goats.

The insulation failure of distribution facilities Our: to aging for the suspension insulator makes it very difficult to detect the failure points and consequently give rise to the long time interruption of electric power, and then it brings on the great failure for the electric power supply in normal state. It has been reported that the Insulator failure occupied above 21% in the total accidents of distribution facilities and caused by the natural drgradation. In present time, the detection of poor insulator has been performed by manpower with the poor insulator detector but the conventional method for failure prevention, such as the poor insulator detector, requires the tremendous repairing time and manpower. This paper presents the possibility for poor insulator detector by observing the phenomena of heat generation of degraded suspention insulator under constant voltage application and during constant time with infrared imaging deagnosis which used in order to make a diagnosis for poor wire collector.
