Mobile Ad hoc Networks (MANETs) have become a viable platform owing to their potential of providing communication without any pre-existing infrastructure and central administrating authority. Mutual support and co-operation among nodes are prerequisites for performing functions in such networks. The scarcity of resources makes it economical for nodes to conserve their resources and misbehave by avoiding participation in the network. Therefore, a mechanism is required to detect and handle such misbehaving nodes and promote co-operation in the network. Existing techniques for handling misbehaving nodes focus only on their current behaviour without considering the antecedent behaviour of nodes. In real world, a node may dynamically change its behaviour in accordance to its requirements. Hence, an efficient mechanism is required for providing security against such misbehaviour. This paper proposes an Adaptive Security Model which contemplates the present as well as anterior behaviour of nodes for providing security against dynamic node behaviour. The adaptivity of the model is nested in its ability to requite well-behaving nodes and penalize misbehaving ones in conformity with their overall behaviour. Simulation results indicate the efficiency of proposed scheme in securing the network from the menace of dynamic behaviour of nodes.

This study analyzed the expressive characteristics of padding in contemporary fashion. The methodology of this study was quantified through documentaries, fashion collections, and internet news. The results of expressive characteristics and methods were as follow. First, variability showed the creation of dwelling space by air filling, detail mode by zipper, and diversity of recycled filling by zipper pocket. It reflected the pursuit of nomadism and subversion of permanence by change of filling. Second, it was sexual symbolicity that showed the blurred androgynous silhouette by air filling and padding bar design of the chest, stomach, shoulder for the male body silhouette. It emphasized male sexual identity and power through the expression of a modern ideal body. Third, decoration displayed various crafts (such as knitting), various fabric such as polapolis, suedette, corduroy, denim, leather, knit, and spangle. It reflected visual pleasure, scarcity and various interpretations. Fourth, playfulness character forms throug hair filling, unfamiliar fashion items, diversity of silhouette and change of uses. It reflected a pleasant feeling through astonishment and surprise, nostalgia involved in memory and childhood play and disembarrassment from reality. Fifth, simplicity showed the elimination of a sportswear's factor with regular wad quilting, elimination of wad quilting, wad quilting following the structural line of clothes and the structual line of clothes omitted. It reflected disembarrassment from stereotype and an emphasis on essential elements.

Korean Internet shopping malls, which provide customers not only with convenient shopping experiences but also with purchasing, warehousing, shipping, and customs clearance services, have been playing a significant role in rapidly transforming Korean consumers into global consumers especially in purchasing fashion goods. Utilizing Ajzen and Fishbein(1980)'s Behavioral Intention Model, which postulates that behavioral intention is determined by attitude and subjective norm, this study identified behavioral intentions toward purchasing foreign fashion goods through Korean Internet shopping malls and the differences of behavioral intentions according to consumers’purchasing experiences on the Internet shopping malls. The data were gathered by surveying female university students living in the Seoul metropolitan area, Korea, and 222 questionnaires were used in the statistical analysis. Mean, standard deviation, factor analysis, t-test, cross tabulation, and $\chi$$^2$ analysis were used. The results indicated that purchasers had more favorable attitudes and subjective norms and higher behavioral intentions than non-purchasers. With respect to attitude, there were significant differences in behavioral beliefs and evaluation of outcomes for the variety and scarcity value factor. With respect to subjective norm, there were no significant differences in normative beliefs and motivation to comply toward friends, people who had purchasing experiences, fashion magazines. and celebrities between the two groups.

Cognitive radio (CR) is proposed as a key solution to improve spectral efficiency and overcome the spectrum scarcity. Spectrum sensing is an important task in each CR system with the aim of identifying the spectrum holes and using them for secondary user's (SU) communications. Several conventional methods for spectrum sensing have been proposed such as energy detection, matched filter detection, etc. However, the main limitation of these classical methods is that the CR network is not able to communicate with its own base station during the spectrum sensing period and thus a fraction of the available primary frame cannot be exploited for data transmission. The other limitation in conventional methods is that the SU data frames should be synchronized with the primary network data frames. To overcome the above limitations, here, we propose a spectrum sensing technique based on blind source separation (BSS) that does not need time synchronization between the primary network and the CR. Moreover, by using the proposed technique, the SU can maintain its transmission with the base station even during spectrum sensing and thus higher rates are achieved by the CR network. Simulation results indicate that the proposed method outperforms the accuracy of conventional BSS-based spectrum sensing techniques.

Purpose: Assessment of the trauma severity associated with the prognosis of trauma patients. But we are having a lot of difficulties in assess the severity because of scarcity of current first-aid records resources. Methods: We presumed that Applying the Revised trauma score which consist of vital signs and GCS score will be helpful to assess the sevirity.This study covers the 10069 patient of Ewah womans hospital (2011.1.1.-2014.12.31) who are able to verify the GCS score from fist-aid records. Results: There is no distinctions between prehospital RTS and hospital RTS. And shows high level of correlation between prehospital RTS and ISS. Conclusion: Therefore we conclude that checking the GCS and RTS at prehospital state will be help to assess the severity of trauma patients.

This study is to understand the characteristics of Korean and Japanese consumers by analyzing the relation among consumer attitudes, concepts, and knowledge about luxury brands. In addition, the present study is to help to establish more effective marketing strategies for luxury companies by providing new data based on consumer knowledge. The author conducted a survey on a total of 816 male/female Korean and Japanese subjects ranging in age from 20 to 50s. The results of this study are as follows: First, Korean consumers have more positive attitudes toward luxury brands than Japanese consumers. Second, regarding the concepts about luxury brands, Korean consumers have concepts of luxury such as "involvement" "symbol of status" "scarcity" and "hedonism"and Japanese consumers have concepts such as "involvement" "ostentation" "high value"and "ornamentation" Third, Korean consumers are more confident in their knowledge and experiences about luxury brand consumption than Japanese consumers. The subjective knowledge has positive impacts on consumer attitudes toward luxury brands and becomes one of the reasons for the friendlier attitudes of Korean consumers toward luxury brands, compared to Japanese consumers. Fourth, the level of objective knowledge of Korean and Japanese consumers is high; but there is no statistically significant difference in the two countries.

The ready-made clothes for obese women are not manufactured systematically due to the diversity and scarcity of their body shape. In this study, we first analyzed and classified 104 obese women's body shape to select four representative subjects. Then, the four subjects participated in wearing test to evaluate the performance of the jacket patterns which are available in the market and widely-used at the same time. The characteristics of the jacket patterns for obese women were also investigated. As to the highly rated jacket in terms of body motion, it was found that difference between the breast width to axilla and the breadth to anterior midaxilla is larger than the other jackets, and the breast width of front body is wider than what of back width. It was noted, however, that the armhole depth and the width of obese women' jackets should not be determined indirectly by the magnitude of the girth around bust, waist or hip as in the case of regular sized women's. It is because body proportion of obese women is different from that of standard sized women.

Body image is important as it is related to self-esteem and can be enhanced by clothing and the degree of enhancement is related to clothing fit. The purpose of the paper is to find the adequate ease distribution of jacket pattern for the obese women who want to slenderize their shape by optical illusion. Subjective evaluation of the visual appearance we collected and, at the same time, 3D clothing air volume was observed for the nine types of experimental jackets with different ease distribution. As results it was found that jacket pattern for the obese women is that the front width of pattern is wider than what of back width in waist and abdomen. It was also noted that there was distance between clothing and skin in the girth around hip of jacket. 3D scanner clearly demonstrated the distribution of ease is useful to find the pattern variables responsible for the slender appearance of the obese women. The ready-to-made clothes for the obese women's clothing should be manufactured systematically in due consideration of the diversity and scarcity of the obese women's body shape.
