Laminate structures are used in the automobile, aerospace, and display industries. The advantages of fiber metal laminates are well known. Fiber metal laminates are useful for reducing the weight and improving impact resistance . However, currently, the mechanical properties of fiber metal laminates are not derived. In this paper, we use thickness as a factor for comparing the properties of laminates of various thickness combinations. The properties fiber metal laminates are analyzed using design of experiments. In addition, the finite element method is used to analyze elastic and plastic strains of fiber metal laminates and aluminum plates. The final goal of this paper is to find a suitable finite element model of fiber metal laminates under bending.

To design ship channel is one of important factors for planning and developing a port. Bends in channel should be avoided if possible, but the channel should be widened, if channel bend is unavoided, to account widened path of a ship in bend for the safe passage of a ship. In this study, Variable Bumper Area(VBA) model is applied to determine ship channel width in bend and channel-bend geometry. The result of this study shows that the width of a channel in bend may be designed as wide as the width in straight lane provided the angle of deflection is less than 30 degree, should be widened for 60degree deflection based on the length of the largest ship using the channel and the angle of deflection.

To design ship channels is one of important factors for planning and developing a port. Bends in channels should be avoided if possible, but the channel should be widened, if channel bend is unavoidable, considering the swept path of a ship for safe passage. In this study, Variable Bumper Area(VBA) model is applied to determine the channel widths in bends. The result of this study shows that the width of the bend may be designed as nearly same size of that in straight channel in case that the angle of deflection is less than 30 degrees, and that of the bend with 60 degrees deflection should be widened based on the length of the largest ship using the channel and the angle of deflection.

This study aims to analyze exterior spatial characteristics of the detached houses in Korea which were designed by professional architects. For this, plans, pictures and data of 113 houses which appeared in architectural publications from July 1998 to June 2002 were collected and analyzed. The results of the study are like this. 1) For the shape of buildings, the number of the non-rectangular shaped buildings is higher than that of the rectangular shaped ones. ; 2) For the location of exterior gardens, the number of the houses with front gardens is higher than that of the houses with back gardens. The exterior gardens are mostly accessed from the living rooms. 3) For the interior gardens, 50% of the surveyed houses have this type of gardens. They are mostly located at the back of the living rooms. The interior gardens are mostly accessed from the living rooms, dining rooms and corridors respectively. 4) For the terraces which are located in the 1st floor, they are mostly accessed from the living rooms. : 5) For the balconies which are located in the 2nd floor, they are mostly accessed from the bedrooms.; 6) For the location of the entrances, they are mostly located in the front side of the buildings and mostly facing south.

The fireplace has been inseparable from the wall. Therefore, the fireplace, which is independently revealed in the living room, is unusual and exceptional. According to the concept of "Served-Servant space" by Louis Kahn, "Servant space" is conceived as an inhabited thick wall and completely separated from "Served space." The fireplace is an apparent servant element, but in Fisher house, it is considered as the single, remarkable and major element composing the house. Paradoxically, this scene of the living room is in conflict with Kahn's ideas on "Servant space." This study sheds new light on the independent fireplace in the conflicting relationship and suggests the similarities with the contemporary cases-Le Corbusier & Philip Johnson-in terms of the stand-alone "Servant element." In the end, the independent fireplace of the Fisher house has transformed into an essential element of the house, as Kahn said that "I feel it[fireplace] represents the presence of a man and therefore is of home."

To design ship channel is one of important factors for planning and developing a port. In most case, the core factors for designing ship channel are the layout and width of dvnnel provided the net underkeel clearance is assessed as safety. In this study, Variable Bumper Area(VBA) model is applied to design and assess ship channel. This model reflects ship's principle dimension, ship domain theory, ship speed, conning officer's ship handling skill and experience and all external forces which cause leeway, set and drift and the change of ship maneuvering characteristics. Full Mission Ship Handling Simulator is used to analyze ship dynamic data according to conning officer's ship control, external forces, etc. This model uses Domain-index for assessing the efficiency and safety of the channel. The proposed model is applied to Ulsan new port plan which has a channel width of 1.5 times the length if the largest vessel, a radius if 5 times the length of the largest vessel in a curve of 57 degree centerline angle and SBM facility adjacent to the lateral edge if channel. The result of this study shows tint the width and radius of channel curve are suitable for the target ship but the difficulty of ship handling is caused by the large course change and SBM located in the vicinity if channel.
