This study was carried out to analyze the publicly announced land price and actual land price compared to the northern and southern region of 361 forest land place in Sanchung county. To decipher factors for making forest land price it used the stepwise regression analysis. And the result of analysis are followings; Y = 332.1973 +0.0099X_26 - 0.3577 X_8+ 0.0291X_24 - 2.6768X_2 - 26.1452X_3 (R^2=90%) and the estimation equation of actual price analyze the publicly announced and actual price compared to the northern and southern regions of Sanchung county of price was obtained as Y = 1035.7976 -185.8280X_21 -3.3937X_1 + 405.6658X_19 -0.4703X_8(R^2=92%). In the northern region, the estimation equation of publicly announced land price by the factors for making forest land price was obtained Y = 176.7875 + 0.0205X_25 -0.1168X_8 + 0.0015X_26 -46.3447X_21(R^2=96%) and the estimation equation of actual price was obtained as Y = 203.0697 + 0.0430X_25 + 0.0027X_26 -28.8276X_4 -46.7856X_21 -0.0007X_23(R^2=90%). In the result of the stepwise regression analysis, it was a showed negative effect of the proximity factor and the positive effect between others factor and land price.

Background: Invasive aspergillosis (IA) is associated with significant morbidity and mortality in patients with hematologic malignancies. We investigated the efficacy and safety of voriconazole (VCZ) when used as salvage therapy for IA in Korean adults with hematologic malignancies who had not responded to prior antifungal therapy. Materials and Methods: We retrospectively reviewed data, collected from January 2007 to October 2008, from patients with proven or probable cases of IA. All were probable IA cases, except for one proven case. All cases were refractory or intolerant to antifungal therapy prior to administration of VCZ. Efficacy and safety were assessed in patients treated with VCZ for more than 3 days and for more than one dose, respectively. A favorable response [complete (CR) or partial (PR)] was defined by significant improvement of all clinical symptoms, signs, and radiologic abnormalities. Results: Fifty patients who met the inclusion criteria were enrolled. There were 27 male and 23 female patients with mean age of 44.4 years (range, 15-65 years). Underlying diseases were acute leukemia (35 cases), chronic myelogenous leukemia (4 cases), myelodysplastic syndrome (3 cases), lymphoma (3 cases) and other hematologic diseases (5 cases). Twenty-two patients had received chemotherapy and 13 patients had undergone hematopoietic stem cell transplantation. The lung was the main infection site (94%) followed by the sinus (6%). Amphotericin B deoxycholate alone was the most frequent previous antifungal therapy. The mean duration of antifungal therapy prior to VCZ therapy was 13.9±8.8 days (2-44 days). The median duration of VCZ therapy was 19 days (interquartile range, 49 days). Sixteen patients (32.0%) showed favorable responses (CR:PR=8:8) at the end of VCZ therapy. The numbers of patients with stable disease, progression and death were, 6 (12%), 6 (12%) and 22 (44%) respectively. Most of those with unfavorable responses had relapsed underlying malignancies or refractory graft versus host diseases. Twelve patients developed drug-related adverse events but only one patient stopped VCZ treatment prematurely. Conclusions: VCZ demonstrated an acceptable level of toxicity in patients with hematologic malignancies but further studies are required to prove its efficacy as salvage therapy.

Necrotizing fascitis is a severe soft tissue infection characterized by extensive necrosis of superficial fascia, suppurative fascitis, vascular thrombosis, widespread undermining of surrounding tissues. Accociated systemic problems are widespread undermining of surrounding tissues, Accociated systemic problems are common, with chronic alcoholism and diabetes being most prominent. Most commonly this disease presents in the extremities, trunk, and perineum. Necrotizing fascitis of dental origing is rare and its fulminating clinical course is not well documented in the dental literature. The present report is a case of necrotizing fascitis following vital extirpation of the pulp in a patient with uncontrolled diabetes mellitus and liver cirrhosis. Originally throught to be caused by hemolytic streptococcus organism or stphylococcus aureus, advances in anaerobic culturing have shown it to be a synergistic bacterial infection involving aerobic and ovligate anaerobes. it is relatively rare in relatively rare in haea and neck regions. If it was not diagnosed and treated in early stages, necrotizing fascitis can be potentially fetal, with a mortality rate approaching 40%. It's treatment requires early recognition, prompt and aggressive surgical debriment and proper supportive cares, such as, antibiotic therapy, fluid resuscitation and correction of metabolic and electrolyte disorder, resolving of the underlying systemic disease. Recently, we experienced two cases of necrotizing fascitis in cervicofacial region, One patient was 60 years old male with uncontrolled Diabetes Mellitus and other patient was 48 years old with steroid therapy during 30 years. Local surgical wound healing was successful but, patients were died after admission, because of lung abscess, gastrointestinal bleeding, septic shock and respiration hold.

Purpose : This study was carried out to evaluate the abnormalites of the speeches of the cleft patients and compare the results of the speech evaluations of a speech pathologist with those of parents. Materials and Methods: Eleven cleft patients' parents were questioned about their children's speech and then the speeches of the cleft patients were evaluated by a speech pathologist and their results were compared with those of parents. Results : Nasal emission was noted in twenty percent of patients, with thirty percent demonstrating hypernasality and all demonstrating no hyponasality and aspirate. And twenty percent of patients show hoarseness. There was no statistically significant difference in the sensitivities to nasal emission between the speech pathologist and parents (p>0.05). However the speech pathologist is more sensitive to hypernasality than parents(p<0.05).

The development of flexible automation in the manufacturing industry is concerned with production activities performed by unmanned machining system. A major topic relevant to metal-cutting operations is monitoring tool wear, which affects process efficiency and product quality, and implementing automatic tool replacements. In this paper, the measurement of the cutting force components has been found to provide a method for an in-process detection of tool wear. The static components of cutting force have been used to detect flank wear. To eliminate the influence of variations in cutting conditions, tools, and workpiece material, the force modeling is performed for various cutting conditions. The normalized force disparities are defined in this paper, and the relationships between normalized disparity and flank wear are established. Finally, artificial neural network is used to learn these relationships and detect tool wear. According to the proposed method, the static force components could provide the effective means to detect flank wear for varying cutting conditions in taming operation.
