The present study was conducted to investigate the single and 2-week repeated dose toxicity of DHP2, a hydrophobic drug delivery vehicle, in ICR mice. The test article was administered orally to mice at the dose levels of 2.5, 12.5 and 37.5 g/kg for single dose toxicity study and at the dose levels of 0, 2.5, 5, and 10 g/kg for repeated dose toxicity study. In both studies, there were no treatment-related effects on mortality, clinical signs, food and water consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, necropsy findings and organ weights of all animals treated DHP2. Based on these results, it was concluded that the 2-week repeated oral dose of DHP2 may have no toxic effect in mice at a dose level of 10 g/kg. In the condition of this study, the no-observed-adverse-effect level (NOAEL) was considered to be 10 g/kg/day for both sexes.

The main purposes of this article are to introduce the theoretical backgrounds and empirical application methods of two different Models for the function of expenditure, and to compare the goodness-o(-fit of the two models: a single-equation model and a complete-system-of-demand-equation model. For the empirical analysis of the single-equation model, a linear formula and a double-leg formula were employed. In order to test the complete-system-of-demand-equation model empirically, the \"Linear Approximation/Almost Ideal Demand System (LA/AIDS)" was used. The independent variables were the total living expense and expenditure categories Price index. The data used in this study were obtained from the quarterly statistics of "The Annual Report on the Urban Family Income and Expenditure Survey (Dosigagyeyonbo)" and "The Annual Report on the Consumer Price Index (Sobijamulgajaryo)," for the years 1994 to 1997. The goodness-of-fit (R-square) was higher with the complete-system-of-demand-equation model than with the single-equation model for the budget share on food (excluding eating-out expenses) and for the share on cultural and recreational activities. However, there was no difference between the two models in terms of the proportion of the expenditure on automobile fuel.fuel.

The purpose of this article is to summary about the application of electromyography and nerve conduction study. Electrodiagnostic studies, which include nerve conduction studies, electromyography, repetitive nerve stimulation, single fiber EMG, late response tests and evoked potential tests are a critical component of the neuromuscular evaluation.

In this article modification of wool fibers and fabrics by pulse corona discharge and enzymes, in particular purified keratinase with a single component has been carried out to improve their surface properties. The shrinkproofing, tensile strength, weight loss, and the primary hand values calculated from the mechanical properties of the dual treated wool fabrics were investigated. In addition, the surface morphology of wool fiber was observed under the dry and wet conditions using an environmental SEM, ESEM.

There have been several papers to illustrate how an information system is used in an automated warehouse system. These papers, however. do not carefully address the role of warehouse planning/control systems nor do they recognize how to integrate the management planning/control systems, and automated warehouse system. This article addresses such issues and shows how a business computer system can be used to integrate and unify the warehouse planning/control systems and the automated warehouse system into it single and highly productive operating system.

Tabu search (TS) has been successfully applied for solving many complex combinatorial optimization problems in the areas of operations research and production control. However, TS is for single-objective problems in its present form. In this article, a TS-based heuristic is developed to determine Pareto-efficient solutions to a multi-objective combinatorial optimization problem. The developed algorithm is then applied to the discrete optimal design problem in statistics to demonstrate its usefulness.

An element of a ring is called strongly nil clean provided that it can be written as the sum of an idempotent and a nilpotent element that commute. A ring is strongly nil clean in case each of its elements is strongly nil clean. We investigate, in this article, the strongly nil cleanness of 2${\times}$2 matrices over local rings. For commutative local rings, we characterize strongly nil cleanness in terms of solvability of quadratic equations. The strongly nil cleanness of a single triangular matrix is studied as well.
