It shows 21st century as a networking society that is moving up the concept of global town and being industrialized with regional and personal connections. Individual's original idea and variety of 21th century may be respected by such environmental change, and age (Literary, human axis, technology axis, nature axis, kaining farming axis are central keyword) of culture that cultural capacity of individual becomes important fetters that create added value is forecasted to become. The moaning for space that is unemployment enemy by change of conceptional environment about cultural life and agreeable quality of life by development of Information-Communication technology may be required newly. As it does interaction along with development of science technique and Information-Communication technology, the future environment of various that complex! Is predicted to form network environment (existence space, cyberspace) newly. Human central interest is risen in technology balance hereupon, and these characteristic escaped in physical system that do with functional special quality and require human central and sensitive interaction. First, if examine about phenomenon by Digitize and chance aspect that is risen in 21th century, Digitize is time that action occurs fusion Tuesday that is various and Blur phenomenon of city·space, and the period to collapse the border between several individual. Second, importance more than man-centered and sensitive aspect of functional physical system is risen by digital age with development of technology medium, and as the five digital senses showed up, it suggests a sensual of the times and therefore the interest and direction get set up for the sensual sides of consumers. Third, special quality is, medium enemy by that digital space connotes meaning disk floret, variability, transparency, space red of extensity etc.. to burn and is digitalised, can be risen by symbolic, original individualities and emotional communication's the importance is required sensitivity enemy who is sympathy horn by fusion anger of individual. Technology of new media may open direction of new communication through interface that did not enjoy so far is going to supply new means that can express own to human

Through various media, damage of both smoking and second-hand smoking has been recognized, and brought global scale of interest in antismoking. In Korea, government has tightened regulations of smoking in non-smoking zone since December, 1980, and after National Health Promotion Act in 1995, non-smoking zone has been gradually expanded. On the other hand, there were law suits to find those regulation towards smokers are either unconstitutional or not for 4 times. In this current state, people need smoking area to prevent second-hand smoking and to consider smokers in multi-unit dwelling. Main purpose of this research is to plan smoking spaces based on various typology of multi-dwelling plan for protection of both smokers and non-smokers' right. The research group collected and analyzed the smoking behaviors in various multi-unit dwelling types such as flat type, tower type, hybrid type and others. Based on those data, the group found three phenomena. First, there are internal regulations in multi-unit dwelling to make non-smoking zone based on National Health Promotion Act and resident representative meeting decision. Second, main smoking activities are occurring at major traffic line and entrances. Third, smoking inside of multi-unit dwelling complex causes second-hand smoking to residents live in $1^{st}$ floor and when they enter. Therefore, one can achieve both smokers' and non-smokers' protection of right by creating a designated smoking space near main entrances of multi-unit dwelling complex to consider smokers' and prevents second-hand smoking by using shaft space, which is in core space, to ventilate tobacco smoke through roof.

This paper proposes full waveform inversion (FWI) for estimating the physical properties of a layered half-space. An FWI solution is obtained using a genetic algorithm (GA), which is a well-known global optimization approach. The dynamic responses of a layered half-space subjected to a harmonic vertical disk load are measured and compared with those calculated using the estimated physical properties. The responses are calculated using the thin-layer method, which is accurate and efficient for layered media. Subsequently, a numerical model is constructed for a layered half-space using mid-point integrated finite elements and perfectly matched discrete layers. An objective function of the global optimization problem is defined as the L2-norm of the difference between the observed and estimated responses. A GA is used to minimize the objective function and obtain a solution for the FWI. The accuracy of the proposed approach is applied to various problems involving layered half-spaces. The results verify that the proposed FWI based on a GA is suitable for estimating the material properties of a layered half-space, even when the measured responses include measurement noise.

This study examined the social trauma experienced by direct victims of accidents and each member of the society affected by grand-scale disasters based on the concepts of collective unconsciousness, archetype, and individuation from Jung's analytical psychology, and their experience of therapy through media. For this purpose, the survivors of the disaster of Sewol that occurred on April 16, 2014, family of the deceased, psychological professionals, and general volunteers were selected as the subjects for one-on-one in-depth interviews and focus group interviews. The findings can be summarized as follows: first, the subjects are suffering from different forms of social trauma such as seclusion and anxiety due to primary/secondary incidents, but there is possibility for them to overcome the social trauma as a social community. Second, the archetypes of life and death, mourning and remembrance are showing in the subjects' everyday lives. In particular, it was found that various archetypes are appearing symbolically through the craft activities in which the survivors are participating most actively. Third, the media therapy program for the victims of the Sewol has limitations in various aspects. However, the fact that the craft activities that are not bound by time and space are highly effective manifests that anyone can take advantage of trauma therapy through digital media that are easily found around them. Finally, this study is significant as it verified the possible individuation of social trauma and identified the limitations of media therapy to suggest its development directions.

Signals of the short wave part of centimetre, millimetre and optic wave length ranges are being broadly used in the communication, location and remote sensing systems with space channels. In this case the presence of discrete non-uniform mediums like orbital debris, space dust and other discrete formations in the propagation channel may have substantial influence upon the characteristics of wave processes. and thus upon the data system quality. Mathematical models for studying the discrete non-uniform mediums effect on the characteristics of electromagnetic wave propagation are analyzed in this paper.

This article is concerned with a two-dimensional problem of micropolar generalized thermoelasticity for a half-space whose surface is traction-free and the conductive temperature at the surface of the half-space is known. Theory of two-temperature generalized thermoelasticity with phase lags using the normal mode analysis is used to solve the present problem. The formulas of conductive and mechanical temperatures, displacement, micro-rotation, stresses and couple stresses are obtained. The considered quantities are illustrated graphically and their behaviors are discussed with suitable comparisons. The present results are compared with those obtained according to one temperature theory. It is concluded that both conductive heat wave and thermodynamical heat wave should be separated. The two-temperature theory describes the behavior of particles of elastic body more real than one-temperature theory.

Recent perspectives on masculinity have changed and are expressed as a genderless style in fashion. Male models wearing womenswear are frequently presented in menswear collections. This study analyzes the genderless men's styles from the Heterotopia concept viewpoint. Heterotopia, coined by the post-modern philosopher Michel Foucault, is a space that deviates from normality and a space of alternative. The research methodology is combined with a literature study and case study. Contemporary men's genderless styles examined through the Heterotopia concept are categorized as transition, deviation, contradiction, crisis, and coexistence. Genderless phenomenon are also accelerated by the development of the media as well as the younger generation who express personality and social messages through a genderless style.
