Response of harbor structure to environmental loads such as wave load, impact load, ship's contacting load, is a fundamental factor in designing of the structure's optimal configuration. In this paper, typical environmental loads against coastal structures are investigated for designing of the optimal harbor structure. Loads to be considered here are wave load, impact load and contacting load due to ship mooring. Statistical analysis for several harbor structure types under the corresponding loads is carried out, followed by investigation of effect of individual environmental load. Based on these, the optimal configuration for the harbor structure is obtained after considerable engineering process. Estimation of contacting load of the ship is suggested using effective energy concepts for the load, and analysis of structural behavior is done for the optimal designing of the structure in the particular load. A guideline for the design process of the harbor structure is established, and safety of the structure is examined by proposed scheme. For verification of the analytical approach, various steel-piled coastal structures and caissons are chosen and relevant structural analyses are carried out using the Finite Element Methods combined with MIDAS/GTS and ANSYS code. It is found using the Morison equation that impact load cannot be a major load in the typical harbor structure compared with the original wave load, and that configuration shape of the structure may play an important role in consideration of the response criteria.

Regeneration of abandoned industrial facilities can heighten the availability through potential values that cannot be found in newly-built buildings and through the sense of overscale space. Furthermore, backward regions can be activated by assigning their identity and establishing social-cultural infrastructures. The aim of the present study is to analyze and integrate of characteristics of design expression based on a case of creative space in Shanghai. A research on the creative space in Shanghi designedly proceeded according to government's extensive administrative support and policy. We keep appearances of industrial buildings as close as possible to their original condition, thereby revealing symbolism and forming unique characteristics that distinguish them from those of other areas. While keeping the shape characteristics of the bridge8, M50, Red Town, 2577 Greative Garden and 1933 Shanghai, we designed spaces in terms of spacial variability, oneness, accessibility and continuity and activated areas by inducing residents' participation and fostering art and cultural oriented facilities. These characteristics of design expression are factors to be considered in regenerating abandoned industrial facilities internally and hopefully they are used as a reference of design plan.

In this paper, we propose a method to segment the bottle label in images taken by mobile phones using multi-gradient approaches. In order to segment the label region of interest-object, the saliency map method and Hough Transformation method are first applied to the original images to obtain the candidate region. The saliency map is used to detect the most salient area based on three kinds of features (color, orientation and illumination features). The Hough Transformation is a technique to isolated features of a particular shape within an image. Therefore, we utilize it to find the left and right border of the bottle. Next, we segment the label based on the gradient information obtained from the structure tensor method and edge method. The experimental results have shown that the proposed method is able to accurately segment the labels as the first step of product label recognition system.

The purpose of this study is to examine if orientation, location of entrance, court yard of existing old houses are consistently maintained when houses are newly built fitting the changed lots system, and the changed road system for Topdong 'Yangdalmal' in the existing old settlements in old center Cheongju. The lots was spilt up into 15 lots in 1913, 38 lots in 1968, and 75 lots in 2010. Among them, The lots maintained are 19 lots and the lots subdivided are 56 lots. 12 houses are newly built among the 19 shape-maintained lots and 41 houses are newly built among the 56 split up lots. Most of the new houses have south-facing orientation. Main entrance near the old road keeps the direction of the previous entry. Houses built in 1970s and 1980s keep their original court yards but they are disappearing year by year by new type of houses in 1990s.

Bletilla striata is an important herb that is used as a paste for texture processing, an ingredient in incense and an additive for preserving calligraphic works and paintings. This study evaluated Bletilla striata, which has been used to preserve and manage the textiles and paper. In particular, this study examined the viscosity of a paste made from Bletilla striata, as well as the mechanical characteristics and antibiotic properties of the fabrics treated with the herb. In terms of viscosity, Bletilla striata paste was less sticky than wheat flour paste, meaning that the former can be applied more evenly to sized fabrics. In addition, Bletilla striata paste has high transparence, ensuring little color difference between the fabrics treated and not treated with the paste. Regarding the mechanical characteristics of the fabrics processed using the KES-FB System, the sized fabrics treated with Bletilla striata paste showed a higher flexibility and recovery rate and than those treated with the wheat flour paste, indicating that the former paste can be more effective in making fabrics maintain their original form and shape. Finally, silk fabrics treated with Bletilla striata showed very high antibiosis. This suggests that the paste can be used to develop antibiotic substances that can preserve textiles.

In this study the stress analysis of orthotropic thin plate with arbitrary shapes for different boundary conditionsis investigated. Meshfreemethod is applied to static analysis of thin plates with various geometries based on the Kirchhoff classical plate theory. According to the meshfree method the domain of the plates are expressed through a set of nodes without using mesh. In this method, a set of nodes are defined in a standard rectangular domain, then via a third order map, these nodes are transferred to the main domain of the original geometry; therefore the analysis of the plates can be done. Herein, Meshless local Petrov-Galerkin (MLPG) as a meshfree numerical method is utilized. The MLS function in MLPG does not satisfy essential boundary conditions using Delta Kronecker. In the MLPG method, direct interpolation of the boundary conditions can be applied due to constructing node by node of the system equations. The detailed parametric study is conducted, focusing on the arbitrary geometries of the thin plates. Results show that the meshfree method provides better accuracy rather than finite element method. Also, it is found that trend of the figures have good agreement with relevant published papers.

Recently, the matrix method has become almost universal tool to solve various engineering problems in conjunction with the rapid development of high speed electronic computers. The method also has been introduced to ship structure analysis in past few years. This paper treats a method to obtain an approximate solution for stress distribution in a web frame of oil tankers. The method is designed to use relatively small computer. The procedure consists of two steps. In the first step, the web frame is idealized to a plane frame of slender members as shown in Fig. 2. Then, the plane frame is analyzed with a matrix method to determine forces and moments in each members. In the second step, the original shape of the web frame is restored and any portion of the frame, in which the stress distribution is desired, is isolated as shown in Fig. 3. Then, again, a finite element method is used to determine the stress distribution in the isolated portion. In this work, IBM 1130 computer in the computation center, SUN has been used. A numerical example with scantlings of an actual ship is worked out to prove the validity of this method.
