This study performed three research methods (destructive, non-destructive, and panoramic image analysis) to determine the most useful for identifying seaweed habitat characteristics. Panoramic images are suitable for understanding the overall seaweed distribution. The composition of the main dominant seaweed species showed a significant difference between the destructive and non-destructive methods using Quadrat. The destructive method showed Rhodophyta dominance, whereas the non-destructive was showed Phaeophyta as dominant. Destructive methods are disadvantageous because they destroy natural communities in sea areas where bleaching is severe. Non-destructive methods are disadvantageous because of the difficulty in analyzing small species. Performing 10 surveys using a non-destructive method was found to explain up to 80% of the species identified by the destructive method. However, considering the difficulty of field investigation, repeating the investigation with non-destructive methods at least 6-7 times is necessary to ensure that more than 60% of the destructive methods can be interpreted. To understand the distribution of oceanic marine algae, performing both destructive and non-destructive surveys are necessary, as each has its own merits and demerits.

The purpose of this study is to the design tendency expression of contemporary architectural matter, I can find out how the architecture is represented using the surface of building in its autonomy. I study backgrounds of contemporary architectural matter, method and their natures. In this case, i can notice that 'framework-dressing' method formed a objectified tectonic system, while it supplied arts with room that they hold priority to architecture. So it makes me find that contemporary architectural matter resided in relationship complicated between things and events. Also, this study on analyzing spatial effect by the figurative language derived by researching the dadaisme, pop art, kinetic art, video art hit In conclusion, analyzing the recent experiments in the expressive qualities of exterior skin, in their use of materials, methods of construction and visual effects, it can be argued that the new skin is inclusive of times, and has autonomic, constant and tactile features. Base on their immaterial vocabularies - limits, material, mouvement, media - these could be characterized as vibrant plates.

One of the most important things to analyze model ground test in plane strain is to observe deformation, accurately, In this paper, the analyzing method of ground deformation by using photos of points on membrane attached on transparent acryle plate of side wall of model ground box is described. First order 4-node isoparametric elements are used to calculate strains of ole cents.

Generally, there are many types of data, such as wear data or irregularity data, are detected for analyzing railway performance. The analysis of railroad wear or irregularity data is most effective method for the efficient railway maintenance. Especially, the track damaged directly by train, have as important position with the inspection data. This study suggest the Life-Cycle performance analysis method and process of railroad by analyzing two types of data, wear data and irregularity data. This analysis methods can be applied to suggest the Life-Cycle performance of railroad based on environmental factors or design factors, such as sleeper type, roadbed type, cant, the radius of curvature, speed, maintenance history and so on.

In this paper, we propose a method to summarize the monthly traffic amount for analyzing network load in mobile communication system. We used the traffic data obtained from a domestic telecommunication company. Based on the statistical properties of the traffic data, we devise an efficient method to summarize monthly traffic amount.

This study represents the method to predict the flow duration curve and primary design specifications of small hydropower plant at hydropower site through analyzing the monthly rainfall data. Weibull distribution was selected to characterize the rainfall data and Thiessen method was used to calculate monthly average flowrate at site. Application of these results, primary design specifications such as design flowrate, annual average load factor and utility factor, annual average hydropower density and annual electric energy production were estimated and discussed for surveyed site located in Daigi-ri, Kangwon province. And performance characteristic model of small hydro-power plant was applied to estimate these specifications.

Continued from study on fresh concrete properties of the part 1, this study is designed for analyzing to the increasing trend of the compressive strength according to the curing method, standard deviation, strength properties of pumping before and after, and a length change to the drying shrinkage. And for quality control, this study is designed for analyzing the early estimation of compressive strength by hydrometer method in diluted concrete solution at the fresh state, and non-destructive testing by the Schumidt hammer at the hardened state.

The statistical method of human sensibility ergonomics is widely used for analyzing interior design because it has standard processes and it can help to get quantifiable results. However applying this method demands repeated intense work and great time and effort is required. In this study, a tool applying Web and virtual reality techniques for statistical human sensibility ergonomic interior design analysis is proposed and the key parts of the tool including database and interface are implemented. The database contains the sensibility adjective table and the physical interior design factor table for analyzing the relationship between human sense and physical design factors. Interface of the tool is implemented using Web technologies, so testers can evaluate interior design samples via standard Web browsers. The 3D control which is an important component of the interface is also implemented. Employing the suggested tool can reduce effort and time for evaluating human sense in Interior design field.

In a modern mass society, a theme park satisfies a consumer's desire of being meaningful in such an imaginary space, which is far beyond the real life. The introductory area of the theme park is a boundary between th real and the imaginary spaces and a fundamental spac of realizing the introductory imaginary space. The objective of this study is to suggest an appropriate method of design application by analyzing the characteristics of the theme park with an example, a theoretical background is first presented by examining the characteristics of the introductory are of the theme park. Than, as an example that reflects well its characteristics, 'Global fair' of the Everland is selected and analyzed based on the developed theoretical background.

The physical tool for analyzing collision accidents narrows down to the conservation law of momentum. The conservation law of momentum which is also utilized to investigate or to analyze a traffic accident is essential to Newton mechanics. This paper suggests an alternative analytical tool based on the conservation law of momentum. Simply put, the tool is a alternative qualitative method of analyzing a car's direction to find out whether it is driving over the centerline This paper proposes a deduction theory that use qualitative information to make a qualitative analysis of which car drove over the center line.
