This study is about a case of web application development using representative commercial BIM platform-linked APIs from Autodesk and Bentley Systems. The development method was aimed at application development using Autodesk's Forge API and Bentley System's iTwin API. The specific development content was limited to the Model Viewer, Issues, and File Transfer API, and the administrator's site. The first research result is that parts with different internal configurations of commercial platforms were independently modularized and developed, and the common front-end was unified. The second research result is that a web front-end technology, was used to visualize 3D models using the viewer API, and the possibility of additional application expansion was discovered.

Since the introduction of digital broadcasting, an additional advanced service called EPG has been brought to viewers. EPG (Electronic Program Guide) helps people select channels or programs. But existing user Interfaces for EPG are not convenient enough for the viewer. TV is the media anyone can access. Therefore, the 'look and feel' user interface is needed to guide the viewer to select their favorite programs without any difficulties. Generally, TV programs can be categorized by their attributes such as genre, broadcasting hours, and TV ratings. At the present moment, those attributes are not categorized systematically enough for easy program navigation. This paper presents how to organize the attributes of TV programs systematically and offers a user friendly interface to help the viewer access their favorite programs by specifying the values of the attributes in any order comfortable to them.

An exhibition administrator, one who works in the exhibition space of museums and exhibition halls, has carried on various tasks in order to improve the exhibition standard and viewer's satisfaction. Although exhibition administrators have a variety of direct perceptions regarding an exhibition in the actual on-site space, a study on their consciousness was absent. Thus, this study was to comprehend the awareness of how the consciousness of exhibition administrators, who directly understand the various matters regarding the exhibition on-site, was structured and to investigate the difference between the consciousness of exhibition viewers and designers. For the study, Q-Methodology, which can scientifically manage the consciousness such as awareness and the acquired attitudes through individual experiences from a specific group, was applied. The classification of 33 Q-methodology research questions was carried out with 18 exhibition administrators, who are working at either national or public museums and exhibition halls in Korea, and the Principal Component Analysis (PCA) using the QUANL PC program was performed. The results of the analysis provided the following 4 types: 'viewer attraction and exhibition method oriented', 'exhibition standard oriented', 'public relations oriented' and 'the public and government's interest oriented'. Each type showed significant characteristics. Additionally, n showed that 'exhibition standard oriented' was the common type after comparing the type of consciousness among the 3 groups of people, such as an exhibition administrator, an exhibition designer, and a viewer. It indicated that the types of 'public relations oriented' and 'the public and government's interest oriented' from the consciousness category for the exhibition administrator were the most independent type, not being found in any of the other groups. And the Significant correlation between the exhibition viewers and designers was identified after examining the Pearson's correlation among the 3 groups.

With the emergence of digital TV broadcasting, various TV channels are provided to a TV audience. But it is getting hard for the audience to find his or her preferred TV programs due to the huge number of TV channels. In order to mitigate the difficulty, channel navigation schemes have been proposed. The schemes predict preferred TV channel from viewer's previous watching histories, and provide the predicted channels when the viewer wants to change TV channel. As channel navigation schemes, there are Most Recently Selected (MRS) scheme providing the most recently watched channel, and Most Frequently Selected (MFS) scheme providing the most frequently selected channel. However, MFS and MRS scheme could be inappropriate to current TV system broadcasting various TV programs in a channel because they are based on the viewer's patterns of watching TV channels. Therefore, this paper proposes an efficient channel navigation scheme, Program Most Frequently Selected (PMFS), based on patterns of watching TV programs instead of TV channels. Simulation results show that the proposed scheme PMFS reduces the seek distance compared to the previous channel navigation schemes, MFS and MRS.

In this paper, we propose an improved reproduction algorithm for a realistic image of the real scene based on the spectral distribution of lights and objects. The proposed method for the realistic image is focused on a more accurate reproduction of an image incident on the sight of the viewer. At first, to reproduce an image accurately incident on a sight of viewer, we used the backward ray tracing method based on spectral distribution of object and illuminant representing its physical characteristic used in real. Next, we propose utilizing the improved shading model of the reproduction algorithm of realistic image by applying Bouguer-Beer's law to consider an optical absorptive property of transparent objects. We also define a new ambient light term which is considered the diffuse reflection of neighboring objects instead of constant ambient light. The simulation results show that the proposed algorithm can reproduce the visually similar image with a scene incident on a sight of viewer.

The newly developed field of media art is quickly making progress to include various and up-to-date forms of expression. Unlike in traditional art, the communication between the art and the viewer has become vastly important, in which the viewer is an active agent who participates and interacts with the artwork. These digital artworks can now be readily observed in everyday places and things, rather than being confined solely in the gallery space. By encouraging open interaction with the public, media art has become more accessible. Accordingly, this thesis examines the construction of a real-time multimedia clock piece using particle systems. Time has always been a significant theme in the realm of traditional art, which continues to be explored extensively in various forms of expression. In an attempt to express the continuity of time and the state of being value of existence based on technological skills, the thesis presents an artwork that uses the popular medium of a clock while also providing both usability and emotional satisfaction for the viewer's sensibility through interaction.

Objective: This study aimed to investigate the reliability and validity of a personal computer-based muscle viewer (PC-BMW) compared with that of a portable ultrasound (P-US) for measuring upper trapezius (UT) and transversus abdominis (TrA) muscle thickness at rest and during contraction. Design: Observational inter-rater reliability study. Methods: Fifty-five healthy participants (25 men, 30 women) participated in this study. PC-BMW and P-US were randomly measured at the UT and TrA muscles. Two examiners randomly obtained the images of all participants in 3 test sessions lasting 2 days. Intra-class correlation coefficients (ICCs), standard error of measurement, contraction ratio, and correlation were used to estimate reliability and validity. Pearson's correlation coefficients were used to analyze the relationship between muscle thickness measures taken from PC-BMW and P-US. Results: The intra-rater reliability ICCs of UT and TrA muscle thickness for the PC-BMW were >0.995, indicating excellent reliability. Inter-rater reliability ICCs for the PC-BMW ranged from 0.963 to 0.987. The P-US also exhibited high reliability. A high correlation was found between the measurements of the two muscles in PC-BMW and P-US (p<0.01). Conclusions: PC-BMW provides clear and excellent images, is pocket-sized and less expensive than a conventional ultrasound imaging system. PC-BMW can be utilized variously and has the advantage of rehabilitative ultrasound imaging. More research is needed to evaluate the utility of PC-BMW for rehabilitation.

Julio Romano decorated the facade of his house in Mantua with a statue of Mercury to give expressions to his ideas on painting. Hereby the painter from Rome could show his home to the world as that of a painter. To be concrete, Mercury was the planet god to which visual artists belonged, and so was basically related to visual arts. In his role to deliver diverse features of art works Mercury could also convey concepts and emotions expressed in a picture to the viewer. The power of a painting to arouse certain emotions or move the mind of the viewer was further connected to the role of Mercury as the guide of the human soul. This function again related the Roman god to the characteristic of a portrait to present absent persons to the viewer. Above the statue of Mercury, a Lucian head of the god is seen, so that they together form the central axis of the facade. This seems to emphasize that the theme of the facade decoration was the powerful persuasive forces of eloquence. The two masks on the left could then refer to sources of eloquence, I.e. various beautiful expressions of a language and its generative process. On the other hand, the masks on the right could represent consequences of eloquence, for instance, prudence, evil effects which come about to imprudent listeners, and other influences on listeners. Finally, it would be useful to remind us of a line from On Architecture by Leon Battista Alberti. According to the humanist architect parts of a building which are seen from the outside, like a facade, should be appropriately designed, since the decoration of a house could play a significant role to enhance the fame and honor of the family and its fatherland. This theory of Alberti could have provided the foundation to the facade decoration of the Casa Pippi which proudly presented the profession of painting to the public in visual form.
