Four crystal forms of cephalexin were prepared and characterized by DSC and TGA. Their dissolution patterns were checked and it was confirmed that the theory of Higuchi was not always correct. All crystal forms were stable.

The cement-based system among S/S(Solidification/Stabilization) is widely used to treat hazardous wastes. In this study, tannery sludge was solidified to evaluate the stabilization effects of using admixtures in the cement-based S/S. Fly ash as substitute also used to increase the strength of the S/S of hazardous waste. The compressive strength measurement and leaching experiment of chromium metal of solidified mortar were carried out to compare and evaluate the physical and chemical characteristics of solidified hazardous waste sludge. From the result of this study, there was increased of compressive strength by using AEW-3(early-hardening AE water reducing agent), and leaching concentration of chromium became low enough to satisfy the regulatory criteria. The successful solidification for the organic contaminant and heavy metal in hazardous waste should enable to treat by cement-based system using early-hardening AE water reducing admixture and fly ash as substituted cement.

Hysterectomy is the most common gynecologic operation. Traditionally, hysterectomy was performed either through an abdominal approach or through a vaginal approach. Recently, laparoscopic hysterectomy is quite often tried. To evaluate the effectiveness and value of LA VH(Laparoscopy Assisted Vaginal Hysterectomy), and to evaluate the possibility whether to rep;ace abdominal hysterectomy to LAVH, we analyzed our clinical cases. This clinical study is a retrospective review of 30 cases of LAVH from May 2002 to February 2003 at the department of Obstetrics and Gynecology, Chung- Ju hospital, Konkuk University. We evaluated age, parity, previous abdominal operations, indications of hysterectomy, combined operation, operating time, hemoglobin change, weight of uterus, hospital stay and postoperativeThe average operating time was 146 ± 42 minutes, the uterine weight was 239 ± 126 grams, and the mean postoperative hemoglobin loss was 1.7 ± 1.4 g/dl. The most common pathologic finding was myoma uteri(37%), and the second most pathologic finding was adenomyosis(20%) and myoma uteri with adenomyosis (20%). Serious complications were not appeared. LAVH provides a shorter hospital stay, quicker recovery, and the acceptable complication rate except incerased operating time than abdominal hysterectomy. This study suggests that LAVH appears more useful than TAH(Total Abdominal Hysterectomy) and could replace abdominal hysterectomy.

Background: Angiogenesis is of crucial importance for tumor growth and development of metastases. Vascular endothelial growth factor (VEGF) has a potent angiogenic activity and mutations of the p53 gene has been thought to upregulate VEGF. The purpose of
Economic Evaluation Model for International Standardization of Correlated Technologies
So Young Sohn,Yoonseong Kim IEEE 2011 IEEE TRANSACTIONS ON ENGINEERING MANAGEMENT - Vol.58 No.2
<P>Standardization is becoming increasingly important, and therefore firms need to begin planning for standardization as early as the R&D stage. While the costs of implementing early standardization are high and have a low probability of success, the potential benefits can greatly exceed the initial costs if the project is successfully managed. In cases of correlated technologies, the degree of uncertainty for implementing standardization is greatly increased; however, correlated technologies can result in a larger benefit and lower cost when they are jointly developed with standardization in mind from the beginning. In this study, we propose an economic evaluation model to analyze both the benefits and costs of correlated technology development and standardization, utilizing the concept of cost-of-ownership model. We also apply the proposed model to a realistic case and perform sensitivity analysis to examine the effects of various parameter settings. This study is expected to contribute to a more accurate evaluation of the economic value of standardization.</P>
