Companies often have to locate their facilities considering competitors' response to their locational decision. One model available in the literature is due to Dobson and Karmarkar, in which a firm has to decide locations so as to prevent competitors from entering the market after the firm's entry. In this paper, we provide new compact binary integer program formulations for their competitive location model and also present an efficient Genetic Algorithm(GA) for finding a (near-)optimal stable set. The GA we propose utilizes a penalty function to handle the feasibility of the problem and modified elitism for better performance of the algorithm. Computational comparisons indicate the superior performance of the GA over the Dobson and Karmarkar's branch and fathom algorithm.

This study was designed to examine the propensity for conspicious consumption of housewives and its influential variables on it. The purpose of this study also is to suggest some fundamental information of consumer education program and policy, in order to prevent consumers from over consumption. The samples were selected from housewives lived in Seoul, in 1997. The 457 subjects were analyzed by Frequency, Mean, t-test, ANOVA, Duncan’s Multiple Range Test, and Regression. Consequently, the propensity for conspicious consumption of housewives is influenced not only by the individual factor, but also by the more effect of psychological and social effects. Therefore, based on the findings it is required that we will have to reinforce the consumer education, so that they have rational consumer’s conscious based upon desirable values. And this education is treated a matter as important by social view.

Purpose: This is a descriptive research that reports incidents of workplace violence among care helpers. Methods: The subjects were 181 care helpers from elderly care facilities and domiciliary elderly welfare centers in Daejeon. Data were collected through self-administered questionnaires from July to November 2011. Subjects were asked to report incidents of violence within the previous six months. Data analysis included one-way ANOVA, and logistic regression analysis. Results: Forty-seven percent of care helpers reported verbal violence, 16% reported being physically threatened, more than 21 % reported sustaining a physical injury with 2% reporting severe physical injuries. Further, 18.8% of the care givers reported being sexually harassed by client. There were differences in reported workplace violence based on service types, service hours and whether there were policies about workplace violence. Conclusion: To prevent workplace violence for carehelpers, it is necessary to make a policy for preventing violence and develop a violence prevention program to meet service characteristics of facility-based and domiciliary care helpers.

Speed, accuracy and smoothness are the important properties of pan-tilt camera. In the case of a high ratio zoom lens system, low vibration characteristic is a crucial point in driving pan-tilt mechanism. In this paper, a novel micro-stepping controller with a function of reducing vibration was designed using field programmable gate arrays (FPGA) technology for high zoom ratio pan-tilt camera. The proposed variable reference current (VRC) control scheme reduces vibration decently and optimizing coil current in order to prevent the step motor from occurring missing steps. By employing VRC control scheme, the vibration in low speed could be significantly minimized. The proposed controller can also make very high speed of 378kpps micro-step driving, and increase maximum acceleration in motion profiles.

Soil contamination in the United States is managed using a risk-based decision making process. In other words, we don't ask, 'how much soil contamination can be cleaned up\ulcorner' Instead we ask, 'how much contamination can be safely left in place\ulcorner' The determination of 'safe' levels of contamination is based upon the potential for exposure and the toxicity of the contaminants of concern in soil. Potential for exposure is determined by evaluating potential exposure pathways from source to receptor given current or reasonably anticipated land use. Soil cleanup goals are then calculated for any complete exposure pathways based upon toxicity and the route of exposure. In some cases, institutional or engineering controls are also used to limit the potential for exposure. In order to prevent a continuous degradation of environmental quality, risk-based cleanup approaches must be combined with strong contamination prevention programs. In addition, alternative risk management approaches should be incorporated into an overall risk reduction strategy.erall risk reduction strategy.

Conversion disorder is defined as a specific and enduring sensorimotor dysfunction that contradicts known neurological or musculoskeletal pathology or physical findings. The patient with conversion symptoms unconsciously adopts these symptoms to convert their psychological stress to a physical phenomenon. Conversion disorder often involves the mimicry of organic symptoms similar to those experienced by a relative or an acquaintance. Because conversion symptoms are produced by psychological stress, specific treatment strategy and reinforcement program are needed for treatment. Treatment comprises avoiding unnecessary medical tests and removing symptoms by using graded exercises given by physical therapists. Clinical therapists must maintain a continuous and detailed follow-up to completely recover from conversion symptoms. The goal of treatment is to emphasize health rather than disease, to resolve physical symptoms, and to prevent recurrence. This study looks into the case reports of 4 patients diagnosed with conversion disorder.
