The tilt angle generation of nematic liquid crystal(NLC) on the homeotropic polyimide(PI) surface by the new Ion beam alignment method is studied. The tilt angle of NLC on the homeotropic PI surface for all incident angle is about 38and this has a stabilization trend. And the good LC alignment of the NLC on the PI surface by ion beam exposure of 45Incident angle was observed. Also the tilt angle of NLC on the homeotropic PI surface by ion beam exposure of 45Incident angle had a tendency to decrease as ion beam energy density increase. So we had known that pretilit angle could be controlled from verticality to horizontality.

As location recognition for autonomous vehicles develops, the need for a precise map for autonomous driving has increased. A precise map must be built based upon accurate position. Recent studies have accelerated research in this area by using various sensors that calculate the accurate position by comparing and recognizing objects around the roads. However, application of such methods is limited because these studies only take objects with significant verticality into consideration. Thus, new research is needed to overcome the limitations: a method that is not constrained by the existence of certain types of surrounding objects shall be proposed. Most roads contain road marking information, such as lanes, direction signs, and pedestrian crossings. Such information on the road surface is a valuable resource for building a precise map. This paper proposes a method of building a precise map by using road marking information.

One of the most important thing in studying the form of the interior architecture is to set up the methodology of the morphological of the morphological analysis. This article tries to introduce one of such attempts namely, that of Dr. Hisao Koyama, professor of Tokyo University , by applying it to one of F.L. Wright's works, the Robie residence . Professor Koyama has outlined a new methodology of morphologically analyzing the interior architectures, by shifting his focus of analysis from the external conditions of a form, such as functional personal and social traits and traits of the time, to the internal conditions of the form as itself. The outcome of the analysis clearly shows that the Robie Residence , classically known by its horizontality, does have a coexisting factor of verticality. This implies that such a method is useful in revealing the aesthetic compounds of the interior architectures, this time that of F.L. Wright , in a more concrete way. Such an outcome can hopefully be applied to the practices of designing the interior architectures.

In apartment housing construction, window frame installation work, which is conducted after the structural framework, is very important, because its completion time directly affects the starting time of successive interior finishing works, as well as the overall construction period. Construction delays in interior finishing works might occur due to problems inherent to the conventional window frame installation method, such as the poor verticality of window frames, and the water leakage around them. The primary objective of this study is to analyze the problems of a 'Gangform integrated PVC window frame pre-installation method' based on its pilot test results. Next, this study proposes an improved conceptual model that enables the end users to enhance the field applicability of this method in terms of productivity, time, and cost. The field applicability of the proposed 'Gangform integrated PVC window frame pre-installation method' was also verified through a survey.

The purpose of this study is to find out various types of stripes pattern and to review its' design expression by analysing stripe pattern and visual effect appeared in western women's fashion after 20th centuries. As regards the visual effect of stripe pattern, on the basis of the stripe pattern's direction laid out, we made an investigation of it by classfying it into verticality, horizontality, slant line and mixture of them according to its' gap and thickness. Here are the 4 features of the stripe pattern appeared in modern fashions. The first, graphic variation based on diverse variation and reconstruction and combination between other motives is being onthe rise as a new expression. The second, colorful stripes of Missoni can be exanpled as the trend of diversification of color. The third, as regards the trend of mismatch in pattern, coordination through mismatch can produce experimental and post-modern image. The fourth, as for the expression of draping effect, we find that stripe pattern can maximaze visual effect through draping by inducing visual stimulus, as well as can express human body in a beautiful manner.

Nowadays, diseases related with breast are increasing rapidly and because of this high quality of resolution images is required to get clear detail specially for early detection and diagnosis. It has a tendency to use digital equipments than analog one in clinic. In this experiment, DR, CR, and Film are used for the resolution applied by AEC. Resolution phantom in DR was $7LP{\cdot}mm^{-1}$ in both verticality and horizontality. In CR, however, it was $6LP{\cdot}mm^{-1}$ in both which was lower this standard. The resolution stayed in range of standard in Film but it showed differences between $11{\sim}14LP{\cdot}mm^{-1}$ Overall, the difference of resolution was displayed Film, DR and CR, in order, which means the study is needed for more high quality of digital images.

The purpose of this study is to examine the status and limitations of the activation plan as a result of the change in urban regeneration paradigm. In particular, the change in housing life was considered following the guidelines of the New Deal project. Specifically, the three types - General Neighborhood, Housing Support, and DongneSaligi - were analyzed from the perspective of organization, space and program. In addition, the master plan and unit project, the organization and progress, and the budget plan were reviewed. As a result, the New Deal project for urban regeneration is importance on economic regeneration, which, unlike the integrated and continuous guide proposed by the government, could limit the individual progress of transitional organizations, 2-dimensional planing and various programs. Thus, first, in order to supplement the organization's verticality and inefficiency in progress, the annual business assessment should be discouraged and the permit and progress of the project should be determined at the local government level. Second, integrated and multidimensional planning is necessary to produce synergy effects in the physical environment. Finally, the link between program unit projects and the economic effects can be considered.

High-rise buildings are widely being constructed in the Middle-East, South-East, and East Asia. These buildings are usually willing to stand for the landmark of the region and, therefore, exhibit some extraordinary features such as super-tall height, elevation set-backs, overhangs, or free-form exterior surface, all of which makes the construction difficult, complex, and even unsafe at some construction stages. In addition to the elaborately planned construction sequence, prediction and monitoring of building's movement during construction and after completion are required for precise and safe construction. This is often called the Building Movement Control during construction. This study describes Building Movement Control of the KLCC Tower, a 58-story office building currently being built right next to the famous PETRONAS Twin Towers. The main items of the Building Movement Control for the KLCC Tower are axial shortening and verticality. Preliminary prediction of these items are already carried out by the structural design team but more accurate prediction based on construction stage analysis and combined with time-dependent material testing, field monitoring, and site survey is done by the main contractor. As of September 2010, the Tower is under construction at level 30, where the plan abruptly changes from rectangle to triangle. Findings and troubleshooting until the current construction stage are explained in detail and implementations are suggested for future applications.
