This paper presentsthe performance study of blind equalizer algorithms for impulsive-noise environments based on Gaussian kernel and constant modulus error(CME). Constant modulus algorithm(CMA) based on CME and mean squared error(MSE) criterion fails in impulsive noise environment. Correntropy blind method recently introduced for impulsive-noise resistance has shown in PAM system not very satisfying results. It is revealed in theoretical and simulation analysis that the maximization of zero-error probability based on CME(MZEP-CME) originally proposed for Gaussian noise environments produces superior performance in impulsive noise channels as well. Gaussian kernel of MZEP-CME has a strong effect of becoming insensitive to the large differences between the power of impulse-infected outputs and the constant modulus value.

Impulsive buying has been considered as one of the major negative shopping behavior. Indeed, it happened more easily in the Internet shopping area. This study attempted to examine the influence of personality on the compulsive buying tendency of college students who are actively shopping clothing and apparels through Internet. The results of the current study showed that there are four types of compulsive buying tendency such as 'diversion', 'no-plan', 'buyer/ product-stimuli' and 'promotion-stimuli.' It seemed that personality such as sensation seeking, need-for cognition, self-esteem, and face-consciousness had influence on the impulsive buying tendency. More specifically, people with low self-esteem and high face-consciousness tend to have more impulsive buying tendency. The relationship between each of the impulsive buying tendency and personality had been discussed.

There are many image segmentation methods having bon published as the results of research so far, however these are for the noise images which can process an image under the general white noise environments. Therefore, these methods has the disadvantages because it is difficult to extract only the accurate parameters, which can distinguish between image and impulsive noise, from image with impulsive noises. So it has a problem about the potential decreasing of the performance according to the impulsive noise for all applications using the present quadtree segmentation. In this paper, we propose new quadtree segmentation using quartile deviation which can extract effectively the image information parameters from a noise image. Therefore our method can apply for various image processing fields because it has a advantage to distinguish an image information from noise image. As the result of simulation, we confirm that the proposed quadtree segmentation is more efficient than the present method when tested on impulsive noise image.

The purpose of this study was to investigate the effect of shopping orientation, and service quality and satisfaction on impulsive buying behavior in two types of apparel store. The sample consisted of 616 females aged 20-30 who were shopping at department stores and shopping malls in Busan. Data were analyzed with factor analysis, t-test, cross analysis and path analysis. The results showed that consumers of department stores showed more strongly convenient orientation than those of the shopping mall, consumers of the shopping mall showed more strongly recreational orientation and practical orientation than those of the department. Stores services of the department were perceived better than that of the shopping mall in promotional services, salespersons' services and environmental services. But it didn't show any differences between store types in product services. Consumers 'satisfaction with the service was greater in department stores than the shopping mall. But it didn't show any difference between apparel store types in the impulsive buying behaviors. Impulsive buying behavior of department store shoppers is directly affected by a shopper' shopping orientation as well as store service quality perceived by shoppers rather than a shopper' satisfaction. The service quality does not have directly related to consumers’ service satisfaction. The causal relationships of impulsive buying behaviors showed similarity in shopping malls and department stores. The perceived quality and satisfaction with store service were higher at department store than shopping malls. In impulse buying behavior of a department store was directly affected by a shopper' shopping orientation as well as store service quality perceived by shoppers rather than a shopper’ store service satisfaction.

Cable TV Home Shopping is one of the popular distribution channels in modem society because of purchasing convenience and saving in shopping time. However, in spite of these advantages, there are some problems because of marketing strategies of many Cable TV shopping companies which stimulate impulse purchases. This study is aimed to find the relationship between buying experience and reaction to impulsive buying stimulus. This study can give a valuable insight in consumer education regarding impulsive purchase behavior in Cable TV home shopping. Study results can also give useful information on the direction of consumer campaign and consumer protection policies. The data was collected by using a questionnaire and the final 496 cases were analyzed by SPSS Win 10.0 program. The major finding were that: 1. Younger, more educated and unmarried consumers tend to response more to impulsive purchasing stimulus. 2. consumers with higher response to impulsive purchasing stimulus had more buying experience, higher shopping frequencies and spent more money in Cable TV home shopping than consumers with lower response. These study results showed that there are some relationship between impulse purchasing stimulus and buying experience in Cable TV home shopping. Therefore, Cable TV Home Shopping companies should provide correct information to the consumers, so they can make resonable decisions. And the consumers should also try to restrain themselves from purchasing impulsively. A law that will regulate all false or exaggerated ads should be provided. To reach righteous and beneficial home shopping culture for both consumer and companies, all these means should be cooperated.

In this paper, the bit error rare (BER) performance of DS/CDMA DQPSK communication system in the presence of multi access interference, impulsive noise and Nakagami fading is investigated. The DS/CDMA DQPSK communication system adopts Maximum Ratio Combining (MRC) diversity reception and error correcting BCH code technique to enhance system performance. Using the derived error probability equation, the error rate performance of DS/CDMA DQPSK communication system has been evaluated and shown in figures to discuss as a function of impulsive index(A), Gaussian noise to impulsive noise power ratio($\Gamma$'), multi access interference(Κ), Nakagami fading parameter(m), the number of diversity branch (Ｌ), the number of error correction symbol (t), PN code sequence length(N) and $E_b/N_0$. The error performance of DS/CDMA-MDPSK signals improve by adopting MRC diversity and BCH(15,7) coding technique in the environment of impulsive noise plus Nagakami fading. From the results, we known that proposed system is affected by multi access interference, impulsive noise and Nakagami fading in radio communication system environment. Also, BER performance of DS/CDMA DQPSK communication system cam be improved increasing either the power of desired signal or the value of Gaussian noise to impulsive noise power ratio. And BCH(15,7) code technique is more effective to restrain the affection of multi access, interference, impulsive noise and Nakagami fading in DS/CDMA DQPSK communication system than MRC diversity reception technique.
