  • The purpose of this study is to provide the visual landscape modelling on Josun royal tombs and surrounding. The visual landscape of traditional heritage is illustrated by the main view points of analysis. This analysis examines limited view points and cannot reflect a reality of environments. Nowadays various equipments and methodologies are developed for the visual landscape research. This study used new tools for analysis which are Sketch up (3D simulation) and mini helicopter (UAV). With those tools, this research examines not only view points of the analysis but also axis views and disincentive environments as a complex analysis. First of all, the research examined 3D modelling for the virtual simulation and drew coordinates and routes for the UAV operating. Secondly, UAV followed this routes and took linear and continuous views that are real scenes. As a result, it drew 3D simulation could illustrate and control the changing of environments such as the forest density and seasonal variations. Thus, comparing both of them shows efficiently landscape analysis. Thirdly, the study compared virtual and real landscape. Using this 3D modelling, this paper able to elaborate heritage environment and surrounding which omitted by view point analysis. Although this study has limitation practice and exercise on the field, the results and suggestions contribute to the various historic heritage managements and conservations. Moreover, it helps to explain the complex and dimensional landscape analysis.

  • The purpose of this study was to discover the landscape visual image of the slope scene and their harmony with surrounding sceneries. This research utilized the basic study tool of psycho-physics and processed the case study of ten types of slope construction scene along the highway. The analysis was performed by the data obtained from the questionnaires and the photos for the slope construction scene. The questionnaires for analysis the image of the slope construction scene and their harmony with surrounding sceneries were designed using semantic differential scale and 5 point Likert-scale. The major findings were as follows. 1. At the part of the visual preferences analysis, the slope revegetation methods showed high level of preferences generally than on the slope structure methods. While the slope revegetation methods were estimated friendly, continuity, harmonious, soft, light and wide, the slope revegetation methods were estimated unstable, female, static, simple, omnipresent, appeared as policeman of weak inclination. Also the slope structure methods were estimated stable, manly, complicated, steep and healthy but rough, unharmonious, unfamiliar and heavy. 2. Psychological factors, related to the satisfaction for the slope revegetation methods were composed of three factors, aesthetic, individuality and physical character. And the slope structure methods were composed of five factors, aesthetic, individuality, stability, physical character, and complexity. 3. At the part of harmony with surrounding landscapes, the slope revegetation methods were evaluated highly but the slope structure methods received the lowest evaluation. Also the harmony analysis with surrounding view on the slope revegetation methods showed degree of high more than average in all texture, form, color and scale but the slope structure methods showed degree of fewer than average degree in form, scale, color and texture.

  • PURPOSES : In this study, field performance evaluation of crack treatment of pavement and the feasibility of surface treatment of pavement are presented. The performance and cost of preventive maintenance methods have been previously verified, and the methods are being used in many developed countries and cities. However, the performance and cost of the system have not been verified in domestic, field applications. Therefore, in order to improve performance, the field performance is evaluated, and a reasonable cost is proposed. METHODS : Visual Inspection was conducted to evaluate the field application and performance of the preventive maintenance method. In addition, the PCI index was calculated from the results of visual inspection of the application area of the surface treatment method, and the performance life of each method was predicted. For the economic evaluation, life cycle cost analysis was performed using the life cycle cost analysis program. RESULTS :In order to evaluate and quantify the field performance of crack repair material, the residue condition of the pavement surface after crack treatment, rather than the performance of the material, is evaluated. In addition, the crack resistance and performance life of surface treatment methods are evaluated. The cost of currently available treatment methods are compared to the common pavement cut and overlay method, and it is determined that the preventive method is not economical based on life cycle cost analysis. CONCLUSIONS :Because of the characteristics of cracking, it is necessary to conduct the evaluation of currently applied methods and the analysis of the cause of damage, by visual inspection. Moreover, in order to evaluate the performance and economic suitability of the currently applied surface treatment methods, it is necessary to acquire information on application sections by monitoring their long-term conditions and performance.

  • It is necessary to apply process algebra and logic in order to analyze and verify safety requirements for Smart IoT Systems due to distributivity and mobility of the systems over some predefined geo-temporal space. However the analysis and verification cannot be fully intuitive over the space due to the fact that the existing process algebra and logic are very limited to express the distributivity and the mobility. In order to overcome the limitations, the paper presents a new logic, namely for GTS-VL (Geo-Temporal Space-Visual Logic), visualization of the analysis and verification over the space. GTS-VL is the first order logic that deals with relations among the different types of blocks over the space, which is the graph that visualizes the system behaviors specified with the existing dTP-Calculus. A tool, called SAVE, was developed over the ADOxx Meta-Modeling Platform in order to demonstrate the feasibility of the approach, and the advantages and practicality of the approach was shown with the comparative analysis of PBC (Producer-Buffer-Consumer) example between the graphical analysis and verification method over the textual method with SAVE tool.

  • Light is a basic force that functions in all the formative arts. Light (brightness) is an important subject of study in that it contains the force to control emotion and has much influence upon the shaping of a visual image and a feeling. If an artist systematizes the characteristics of brightness and creates an image, he or she can acquire a useful tool of expression. Because light is a powerful medium of expression of a visual image, a study on the characteristics of brightness for the emotional expression of an image in the contextual relationship with narratives seemingly has a crucial meaning. Emotion is influenced by a visual image very much, and a visual image is inevitably influenced by light. The brightness by light is basically classified into bright, dim, and dark. And the three basic stages of brightness specialize an image according to the setting of scope of maximal and minimal luminosity, and the image is further differentiated by the size of bright portion or dark portion. Since emotion is such a phenomenon as immaterial and psychological, it is difficult to break down it. Furthermore, clarifying the principle of an image in which the shade of light is associated is impossible. However, the width of luminosity and the change of size can give quite a change to a visual image, and the visual image has further influence upon man's emotion too. Although the influence of brightness upon a visual image varies with extents, circumstances, and personal tastes and interests, even the same image clearly changes with the adjustment of brightness.

  • Objective : The purpose of this study was to investigate the correlation between hand dexterity and visual-motor skills of preschoolers. We searched for the correlation between two test results, which were the 9-Hole Peg Test performance time and the visual motor integration test(VMI) performance score. Then, we also compared the 9-Hole Peg Test performance times with the VMI performance scores according to sex and age. Method : The participants were fifty normal children ranging in age from four to six years living in Busan. We used two test methods which have high reliability and validity. One was the 9-Hole Peg Test to evaluate hand dexterity, and the other was the VMI to the evaluate visual-motor skills of these young children. Results : First, over the entire range of the participating children, there was a high correlation between the performance times from the 9-Hole Peg Test and the VMI performance scores(r=-.682). Second, there was not a statistically significant difference between the performance times from the 9-Hole Peg Test and the VMI scores according to sex. Third, there were significant differences between the hand dexterity and visual-motor skills according to the children's age(p<.001). Conclusion : This study proved that there is high correlation between hand dexterity and visual-motor skills of the preschooler. Occupational therapists in preschool service should consider that visual-motor skills need to be compatible with hand dexterity in both evaluation and therapy. In addition, hand dexterity and visual-motor skills improved according to advances in age, so we must give graded tasks to proper age groups through concrete analysis of activity. By doing this, children can get the better therapeutic effects.

  • Visual language is 'a form of communication without text'. Visual language is one of the strongest methods to spread knowledge. Uniforms could be interpreted as a symbolic language that establishes order in this complicated modern society by placing identity and responsibility on each members of various different organizations. In light of the above, the purpose of this research paper will be to analyze police uniforms of U.S.A, Great Britain, Italy, France and Korea as a form of visual language and interpreting them in terms of visual design in order to understand the fundamental ideas behind the designs and the effective applications thereof. Upon analysis of traffic police uniforms of each individual county mentioned above by separating each uniform's distinctive design, pattern, color, material and decoration based on visual factor, three characteristics of authority, dynamic functionality and friendliness were derived from comparing and analyzing each country's distinctive uniform design. The traditional unique role of police in our society was to maintain social order as their nature inherently possesses characteristic of authority and preservation, but has since undergone transition in many countries to appeal to the broader public by incorporating friendliness and dynamic functionality. Analyzing police uniforms in terms of visual linguistic sense requires a much more profound process of understanding beyond simple interpretation of configurative shapes. In conclusion, the true purpose of uniforms is to include and portray images of mankind's desire toward expressing ideas like 'mankind's bias toward existence beyond theirselves and the exercise of force through authority' and materializing such ideas into a physical form.
