This study was made to investigate the differences in Korean woman's perceived makeup image and self-consciousness according to their expectation level in socio-psychological effect of makeup, and to gather information needed for the better understanding of cosmetics consumers and more effective marketing activities of cosmetics industries. Normative-descriptive survey method using questionnaire was employed for the present study. The survey was conducted in August 2001 and the sample consisted of 942 women between the ages of 18 and 50 residing in Seoul and Kyungi province. Data were analyzed by SPSS package. Factor analysis, ANOVA, and MANOVA were employed for the analysis of the data. The results are as follows : (1) Six factors emerged from the data related to the category of expected socio-psychological effect of makeup. Those factors were named as "increasing positiveness", "refreshment", "covering weakness", "self-expression", "consideration for others", and "the tool for self-change". Four factors were found in the category of makeup image, and the factors were named as "refinement", "nobility", "favorable impression ", and "personality ". (2) There was a tendency that those who highly expect the socio-psychological effect of makeup have more positive self-image. Considering this differences in self-image according to the level of expected socio-psychological effect of makeup. service activities for the consumers' positive opinion and attitude to the effect of makeup are needed, and it seems that those service activities will have a good influence on the consumers' emotional health. (3) Subjects with higher level of social anxiety showed higher expectations in refreshment, covering weakness and self-expression. Considering this trend, marketers have to make an constant effort for the variety of cosmetics and makeup manner by which consumers satisfy their expectation in makeup. It seems that the satisfaction of their expectation on the help of makeup effect will contribute to lessen social anxiety, and to get emotional stability. (4) Subjects with higher personal self-anxiety showed higher expectations of the effect. "increase of positiveness". Therefore, if the product advertisement imply the content of increasing positiveness effect of makeup, it might appeal more easily to their consumers.imply the content of increasing positiveness effect of makeup, it might appeal more easily to their consumers.

An innovative biopolymer known as the Rhizobian gum has been developed in France, which shows some dramatic refreshing effect on the skin. The origin of this innovative project takes its source in the natural environment, and in particular the natural environment of the roots of sunflowers and wheat, where a symbiotic bacterium has been discovered. It is a Rhizobium bacterium, which is hosted by the roots, and which is able to synthesize a specific polymer showing a dramatic water binding capacity. This polymer is in particular synthesized in period of drought, and its biological role is to concentrate the small amount water present in the soil in order to take it available for the root, which becomes then able to absorb it. This vital mechanism allows the plant to survive despite a severe climatic environment. This basic research has been conducted in collaboration whit the French National centre of scientific Research (CNRS), and has lead to the isolation of the Rhizobium bacteria. Rhizobian gum is a branched biopolymer consisting in the repetition of a polysaccharide unit of 3 molecules of glucose, 3 molecules of galactose and 1 molecule of glucuronic acid, whit one pyruvate group an average 1.6 acetyl groups. The fresh effect of Rhizobian gum is a strong sensorial impact that 100 ％ of the consumers are able to perceive, and which is judged very pleasant by most of them. In addition to this, a large majority of consumers are perceived, and which is judge very pleasant by most of them. In addition to this, a large majority of consumers also feel a very pleasant relaxing sensation. Smoothness and softness are also felt by most consumers and qualified positively by most of them. These qualities guarantee a strong impact on today's consumers.

EMU(Electric Multiple Unit) of Seoul Metro are equipped with air conditioning and six line flow fans for air circulation. In summer, the air conditioning and line flow fans usually work at the same time. Recently, high oil price leads more people to use public transportation, which in turn makes them feel hotter inside the rolling stocks and complain about air conditioning state. In order to improve indoor air quality in summer, it is inevitable to increase the cooling capacity of air conditioners, which costs a lot of money. Thus, we need to raise cooling efficiency by rearranging existing devices effectively. In this study, we found a better way to improve refreshment inside the trains by changing the operation method of line flow fans and door opening systems. The results will help improve the cooling efficiency of EMU in summer. Also, more precise experiments and analyses of our data can lead to various methods to increase energy efficiency.

In this study, software-based countermeasures against a side-channel cryptanalysis of the Rabbit stream cipher were developed using Moteiv's Tmote Sky, a popular wireless sensor mote based on the Berkeley TelosB, as the target platform. The countermeasures build upon previous work by improving mask generation, masking and hiding other components of the algorithm, and introducing a key refreshment scheme. Our contribution brings improvements to previous countermeasures making the implementation resistant to higher-order attacks. Four functional metrics, namely resiliency, robustness, resistance, and scalability, were used for the assessment. Finally, performance costs were measured using memory usage and execution time. In this work, it was demonstrated that although attacks can be feasibly carried out on unprotected systems, the proposed countermeasures can also be feasibly developed and deployed on resource-constrained devices, such as wireless sensors.

Based on input and output data pairs of nonlinear systems, this paper proposes a simple and effective Just-In-Time (JIT) method, called Direct JIT Control, for nonlinear control design. It uses an inverse model of controlled plant to compute an initial control action, and then adapts the initial control action by adding a fine-tuning control action, depended on the errors between the real outputs and the expected reference signals. Meanwhile, the proposed JIT method accomplishes the adaptation of the inverse model just simply by means of the refreshment of input and output data pairs. In addition, the JIT modeling technique guarantees this method to obtain an approximate inverse model of the controlled nonlinear plant in the neighborhood of a query. Based on a ...
