Clinically healthy Korean adult cattle (20 females and 20 males) were selected and subjected to the experiments on the determination of erythrocytes and total leukocytes values at the stages of pre and post-slaughting. Throughout the studies the following results were obtained. 1. The erythrocytes values, at the stage of the pre-slaughter, of females and males were $6.070{\times}10^6/cmm$ and $6.175{\times}10^6/cmm$ respectively. In the case of post-slaughter stage, $7.780{\times}10^6/cmm$ and $7.705{\times}10^6/cmm$ were obtained for female and male respectively. In comparison on the values of erythrocytes between pre and post-slauglnter stages, the mean value of the latter has been increased significantly. 2. The total leukocytes value, at the stage of the pre-slaughter of females and males were 9,525/cmm and 9,630/cmm respectively. In the case of post-slaughter stage, 7,545/cmm and 7,510/cmm were obtained for females and males respectively. In comparison on the values of total leukocytes between pre and post-slaughter stages, the mean value of the latter has been decreased significantly.

Robots are widely utilized in many fields, and various demands need customized robots. This study proposes an optimal design method based on swarm intelligence for selecting the kinematic parameter of a manipulator according to the task space trajectory desired by the user. The optimal design method is dealt with herein as an optimization problem. This study is based on swarm intelligence-based optimization algorithms (i.e., ant colony optimization (ACO) and particle swarm optimization algorithms) to determine the optimal kinematic parameters of the manipulator. The former is used to select the optimal kinematic parameter values, whereas the latter is utilized to solve the inverse kinematic problem when the ACO determines the parameter values. This study solves a design problem with the PUMA 560 when the desired task space trajectory is given and discusses its results in the simulation part to verify the performance of the proposed design.

Breast cancer is the most common malignancy in women, both in the developed and developing countries. Anthocyanins are natural coloring of a multitude of foods, such as berries, grapes or cherries. Glycosides of the aglycons delphinidin represent the most abundant anthocyanins in fruits. Delphinidin has recently been reported to inhibit the growth of human tumor cell line. Also, delphinidin is a powerful antioxidant that reportedly exerts beneficial effects in patients with advanced cancer by reducing the level of reactive oxygen species and increasing glutathion peroxidase activity. This study investigates the effects of delphinidin on protein ErbB2, ErbB3 and Akt expressions associated with cell proliferation and Bcl-2, Bax protein associated with cell apoptosis in MDA-MB-231 human breast cancer cell line. MDA-MB-231 cells were cultured with various concentrations (0, 5, 10, and $20{\mu}mol/L$) of delphinidin. Delphinidin inhibited breast cancer cell growth in a dose dependent manner (p < 0.05). ErbB2 and ErbB3 expressions were markdly lower $5{\mu}mol/L$ delphinidin (p < 0.05). In addition, total Akt and phosphorylated Akt levels were decreased dose-dependently in cells treated with delphinidin (p < 0.05). Futher, Bcl-2 levels were dose-dependently decreased and Bax expression was significantly increased in cells treated with delphinidin (p < 0.05). In conclusion, I have shown that delphinidin inhibits cell growth, proliferation and induces apoptosis in MDA-MB-231 human breast cancer cell lines.

Purpose: The dental implant should be enough to endure chewing load and it's required to have efficient design and use of implant to disperse the stress into bones properly. This study was to evaluate the stress distribution on a supporting bone by lengths and diameters of the implant fixture. Methods: The modeling and analysis of stress distribution was used for the simple molar porcelain crown model by Solidworks as FEM program. It was designed on applying with tightening torque of 20 Ncm of a abutment screw between a cement retained crown abutment and a fixture. The fixtures of experimental model used 10, 13mm by length and 4, 5mm by diameter. A external vertical loading on the two buccal cusps of crown and performed finite element analysis by 100 N. Results: The maximum von Mises stress(VMS) of all supporting bone models by fixture length and diameter were concentrated on the upper side of supporting compact bone. The maximum stress of each model under vertical load were 164.9 MPa of M410 model, and 141.2 MPa of M413 model, 54.3 MPa of M510 model, 53.6 MPa of M513 model. Conclusion: The stress reduction was increase of fixture's diameter than it's length. So it's effective to use the wider fixture as possible to the conditions of supporting bone.

The dynamic instability characteristics of laminated composite stiffened shell panels subjected to in-plane harmonic edge loading are investigated in this paper. The eight-noded isoparametric degenerated shell element and a compatible three-noded curved beam element are used to model the shell panels and the stiffeners respectively. As the usual formulation of degenerated beam element is found to overestimate the torsional rigidity, an attempt has been made to reformulate it in an efficient manner. Moreover the new formulation for the beam element requires five degrees of freedom per node as that of shell element. The method of Hill's infinite determinant is applied to analyze the dynamic instability regions. Numerical results are presented to demonstrate the effects of various parameters like shell geometry, lamination scheme, stiffening scheme, static and dynamic load factors and boundary conditions, on the dynamic instability behaviour of laminated composite stiffened panels subjected to in-plane harmonic loads along the boundaries. The results of free vibration and buckling of the laminated composite stiffened curved panels are also presented.

As social media are emerging as essential communication channels for corporates in all areas, luxury jewelry brands have implemented enhanced strategies for brand story videos by creating brand channels on YouTube. In this study, a comparative analysis of the videos made available by Cartier and Tiffany&Co. on their YouTube Brand Channels was conducted, with the aim of identifying their strategic characteristics. The research method encompassed, both literature review and empirical investigations. A quantitative analysis was conducted by means of the 'HEART' model, a type of luxury jewelry brand story, and the following common strategic elements were identified. First, in their brand story videos both brands focus primarily on 'theme'. Second, 'relationship' and 'artisanship' are emphasized in addition to 'theme'. Third, the videos incorporate high level aesthetics to stimulate the fantasies and dreams of their audiences. The strategic differences between the brands are as follows. : First, 'artisanship' is given the greatest significance along with 'theme' in Cartier videos, while 'relationship' has prime significance in Tiffany&Co. videos. Second, a difference between a European approach and an American approach towards luxury brand building is evident, with Cartier hosting exhibitions while Tiffany&Co. provides gala videos instead.
