This study analyzed the creative properties of public service advertisements and public content in outdoor advertising. The results of a case analysis focusing on outdoor advertisements for fundraising are as follows. First, government ministries were mainly found as advertisers. Second, most of the advertising messages were about policy promotion by the government and public institutions, with few public content or public interest messages. Third, in terms of expression, text took up more weight than visual elements, and illustrations were the main visual expression element. This proves that the public content of domestic outdoor advertisements mainly has a strong purpose of conveying direct information.

In this study, the effect of the hole spacing and the detonation delay time in the long hole blasting of two free surface rock mass on the variation of the principal strains in the vicinity of blasting holes is investigated by use of the finite element program, Visual FEA. The cross section perpendicular to blasting holes is modelled and the maximum principal strains at some major points in the cracking zone are examined. As a result, it was found that the maximum principal strain in the cracking zone becomes larger in the long hole blasting with the narrower hole spacing and the longer detonation delay time. The maximum principal strain was affected by the detonation position in charge hole.

A way to measure the second parameter $A_2$of CT specimens is described. The displacement $\delta$$_{5}$ which is measured continuously from visual images of the lateral surface during crack growth is used to calculate the A, as a function of crack growth. The crack length is measured by DCPD(Direct Current Potential Drop) method and the J-resistance curve is determined according to ASTM standard E1737-96. To prove the validity of this method, three dimensional finite element analyses were performed, and variations of the displacements $\delta$$_{5}$ and $A_2$along the thickness were explored. As the result, it has been shown that the $\delta$$_{5}$ measured from the visual images of the lateral surface and the corresponding $A_2$can be regarded as the average through the thickness for 1T and 1/2T specimens of SA106Gr.C steel.steel.

Biophilic design gives human beings positive and valuable experiences in nature. The experience in nature in the architectural environment is mainly symbolic and metaphorical, and is based on visual sensations such as color, form, and image. Recently, modern people living in a modern and simple style indoor space have a desire to pursue visual stimuli for interest or pleasure. This desire can be satisfied through color, lighting, and finishing plan. Therefore, the purpose of this study is to propose a biophilic design color palette based on the empirical characteristics and properties of biophilic design. The methods used in this study are as follows. First, the biophilic design factors and natural landscape preference criteria are examined. Second, based on the review results, natural landscape images are selected and color information for each biophilic design element is extracted according to the vertical and horizontal directions. Third, color information is converted to NCS color code and palette range and hue range are derived through the analysis of ratio and average values. Finally, based on the analysis results, biophilic design color palette is proposed for each element. The results of this study might be useful as basic data in establishing biophilic design strategies and applying them to architecture and interior construction.

This study attempts interpretation of vertical montage expressed in assoziation montage focused on animation, Paprika. Montage has been continuously studied by Pudovkin, Eisenstein, Jacques Aumont and others till now. However, existing studies focused on the visual image of montage. Image is made of visual element and aural element. These two interact with each other and maximize the effect. It is believed that the study subject can be approached in more depth, if aural elements would be analyzed based on the assoziation montage which analyzed visual image in previous studies. Accordingly, this study explores and analyzes how vertical montage has been used in logical montage and optical conflict montage and what meanings they generated. The analysis results suggested followings. In logical montage and optical conflict montage, vertical montage complemented visual image by natural concurrence as a whole. Vertical montage also showed linked relationship, which reflects overall emotion by melodious concurrence. In addition, when there was melodious concurrence at certain time, place or unclear space, the elements showed continuity which made them link with relationship. However, when the role that cuts that continuity, in other words, when the tonal element, which let audience partially immerse, would be properly used when the space and time would change or get reversed, the effect was maximized. It also expressed a turning point of an event and enhanced the concentration of audience on the characters.

This research progressed space evaluation test with 3D simulation for exterior space of detached housing area among the Seoul spaces of child sex offense in 2010. Based on changing analysis on natural surveillance by spatial changes of each physical element, the purpose is to suggest effective construction planning measure for preventing child sex offense. The results of research are as follows. First, natural surveillance of space's height differences and width differences were compared and analyzed. As the result, footpath shows that stairs of slope didn't make lots of effects on visual block, not block of spatial moving, because of the difference of stair height. Also, in case of parking space, visual connection with footpath is expanded when designing pilotis rather than heightening floor height, so activities of exterior people could be seen more easily. Therefore, natural surveillance was higher. Second, natural surveillance of architectural elements by changes of footpath' width was compared and analyzed. As the result, openness of footpath should be secured rather than openness of architectural element. And, planning autonomy of architectural form could be more expanded when securing openness of footpath.

This paper presents a physically-based haptic rendering algorithm for a deformable object based on visual information about the intervention between a tool and a real object in a remote place. The physically-based model of a deformable object is created from the mechanical properties of the object and the captured image obtained with a CCD camera. When a slave system exerts manipulation tasks on a deformable object, the reaction force for haptic rendering is computed using boundary element method. Snakes algorithm is used to obtain the geometry information of a deformable object. The proposed haptic rendering algorithm can provide haptic feedback to a user without using a force transducer in a teleoperation system.

As the gaming industry grows, the need to understand and study on game Addiction and overindulgence have also grown. For this object, in this study, the author first studied how game elements and game mechanisms were categorized by using previous studies. As a result, game elements are divided into three elements that compose visual, competitive, and probability elements. And the game mechanisms that establish three elements were grouped into subcategories. Risk of competitive and visual element that effect on overindulgence is depended on what mechanism has used. But, in the probability element, Gambling mechanism must be viewed in terms of addiction, not overindulgence.

A study of adiabatic shear band formation and propagation of 4340 steel was done using the stepped speciment which was subjected to high velocity impact. The high velocity impact was performed on compression Hopkinson bar impact machine. After the controlled impact, the specimen was prepared for visual inspection. Numerical simulation was also performed with same geometrical dimension using explicit time integration finite element code. Experimental results were then compared with the numerical prediction. It was found that the numerical prediction is quite accurate, average thickness of adiabatic shear band is about $10{\mu}m$, the macro crack around shoulder is due to folding, and the deformation control ring is effective to freeze the propagation of adiabatic shear band.
