Human mind can be divided by conscious and nonconscious. The action that can be seen by eyes express of conscious world, but brain researchers tell us that the world of nonconscious more occupied than world of conscious. In this paper, we divide conscious and nonconscious of world in basic love model of Romeo and Juliet, and then we represent complex number for the conscious and nonconscious. We also display as time series and phase plane for their behavior. Finally, we confirms the existence of nonlinear characteristics in their behavior.

Recently, there is growing recognition that we should protect an environment in all industries. As one of the OECD in the world trade market, we have to apply the Envirormentally Conscious Logistics System(ECLS) considering an environment seriously, and to implement environmentally conscious logistics activities. A packaging of entire logistics system have to also do it. Therefore, the objectives of this study were to discuss and to make an overture which an environmental packaging system of logistics system is by introducing a case study.

This study is done in order to find the solutions that we are facing on social and ecological crisis around the world. The basic survey was done on college students who will mostly become city residents in the future. Students collect information about the amount of the waste and the way of disposition for a week. The analysis how they produce and dispose waste will show what influence their behavioral decisions. The findings are first, students are very conscious of the importance of environmental conservation. But they value little and they don't have proper knowledge. Second, sex was the decisive factor, women tend to behave eco-friendly. But the more they are conscious about environment, the less they behave eco-friendly. The more they spend allowances, the less they are conscious of environment. Third, they recycle waste at home during the weekend, but not during weekdays at school because there is no recycling bin or they are not economically responsible.

With the effectuation of Kyoto Protocol, one of the important movement throughout the world is reducing the emission of greenhouse gas which is the main reason of making global warming. The actual factor of greenhouse gas is CO2, and in year of 2002 20% of total CO2 emission was produced only through transportation throughout the South Korea. In the contrary, the recycling of municipal wastes in South Korea was 44.0% in 2002, but it will be targeted upto 53.5% in 2011. All of these show environment-conscious logistics should be implemented together throughout the each stage of distribution with the development of product and service. This study applied survey research for the activities affecting to the emission of CO2 and packaging wastes produced from transportation and packaging stages in logistics area. For this, survey questionary was constructed with five specific areas - strategy, transportation & distribution, custody, packaging, and information. Based on the 148 returned survey questionaries, this study analyzed 52 categories and finally suggests necessary modal shift, collaboration & co-operation in logistics, LCA(life-cycle assessment), and other promoting policies for the environment-conscious logistics in effective way.

The purpose of this study was to analyze the formative beauty of metro sexual expressed on the 21C men's fashion. in 21C, metro sexual is being accepted as an object to lead the world consumption culture, and it is said to be most appropriate to the definition as a model that can determine the most modern men. Moreover, with well being life style, it shows characteristic that expresses chic sense through fashion. The results of the study were as below. 1. In recent men's wear, sensory feminine that looks young and trendy is being presented through clothes, rather than the image of men who are strong. Therefore, by wearing splendid flower print, bold color and gorgeous accessories, men send off their attractions. 2. The recent body king syndrome gave new aesthetic value on men's body. Therefore, men's body is becoming cultural icon of metro sexual as another face that shows social status and cultural taste. 3. The men's image of metro sexual that is felt from softer skin and hair than women, and well-built body is appealing more through body conscious look. Here, men's body silhouette is being sublimated aesthetically through design with various materials such as see-through and leather etc., and this is body conscious image that can be seen only in metro sexual. Like this, metro sexual fashion sense was expressed by feminine softness sometimes, and beautiful body silhouette sometimes by expressing one's sexiness enough, being away' from conceptual masculine. Therefore, the appearance of metro sexual can be understood that men's body exposure is becoming a social virtue that expresses beauty.

As one of the developing countries in the world trade market, we have to apply the environmental concept at the development of a product for environmentally conscious manufacturing system(ECMS). Traditionally, Production control model has been studied based on a new product manufacturing environment. However, ECMS such as a remanufacturing system should be developed and implemented for highly competitive environment in 21C. The objective of this study was to extend the research of production control model by applying it at the remanufacturing environment of ECMS and to test the applicability of current production control model at the remanufacturing environment by the simulation experimental study.

This paper approaches the subject of consciousness and unconsciousness from a mathematical point of view. It sets up a hypothesis that when unconscious state becomes conscious state, high density energy is released. We argue that the process of transformation of unconsciousness into consciousness can be expressed using the infinite recursive Heaviside step function. We claim that differentiation of the potential of unconsciousness with respect to time is the process of being conscious in a world where only time exists, since the thinking process never have any concrete space. We try to attribute our unconsciousness to a special solution of the multi-dimensional advection partial differential equation which can be represented by the finite recursive Heaviside step function. Mathematical language explains how the infinitive neural process is perceived and understood by consciousness in a definitive time.
