The purpose of this study was to present the necessary data concerning the selection and development of floor-coverings in view of slipperiness by comparing the relationship between CSR measured with O-Y·PSM and RCOF calculated from the result of gait analysis. CSR was calculated from maximum tensile load(Pmax) divided by perpendicular load(785N) when pulled 18 degrees upward the moment the bottom of the slip piece contacted the surface of the test piece. RCOF was calculated based on Fy/Fz from when horizontal load reached the maximum point within the sections from the moment the front of outsole touched the test piece to when pulled off the test piece. The results from the research were as follows: (1) Range of CSR was 0.15-1.02, which meant the differences of slipperiness of the test pieces definitely showed up. (2) RCOF are inadequate to express the characteristic about the slipperiness of the floors, since there were no differences between the test pieces.

Fractures of the orbital floor and walls are among the most frequent maxillofacial fractures. Virtual three-dimensional (3D) planning and use of patient-specific implants (PSIs) could improve anatomic and functional outcomes in orbital reconstruction surgery. The presented case was a victim of a terrorist attack involving improvised explosive devices. This 58-year-old female suffered severe wounds caused by a single piece of metal from a bomb, shattering the left orbital floor and lateral orbital wall. Due to remaining hypotropia of the left eye compared to the right eye, late orbital floor reconstruction was carried out with a personalised 3D printed titanium implant. We concluded that this technique with PSI appears to be a viable method to correct complex orbital floor defects. Our research group noted good aesthetic and functional results one year after surgery. Due to the complexity of the surgery for a major bony defect of the orbital floor, it is important that the surgery be executed by experienced surgeons in the field of maxillofacial traumatology.

The breakdown of machines lead to the lateness of parts and the change of schedules. Its treatment is very important problem in the shop floor control system. In this study, we present an algorithm minimize the lateness, earliness and change of schedule by controlling machining speed of available machines. Production time and production cost required to manufacture a piece of product are usually expressed as a unimodal convex fuction with respect to machining speed, and each has its minimal point at the minimum time speed or the minimum cost speed, and a speed range between these two speeds is called 'efficiency speed range'. Therefore, the algorithm determines the machining speed in the efficiency speed range. An example is demonstrated to explain the algorithm.

The purpose of this study is to distinguish the causes of broken glass on doors or windows when it is originally kept among the remains on the floor in fire site - whether it was broken due to heating or outer power-through test and characteristics of the broken plane including the pattern on the plane. Addition to it, the study tries to find characteristics to judge the point and direction of breakdown through the analysis of glass broken by outer power. With two assumed causes - a) breakdown due to heating and b) breakdown due to outer power-3 pieces of glass plates ($30cm{\times}30cm{\times}5mm$) were tested for each case, getting the results as following: First, for the glass broken due to the change of temperature, the broken plane is of slow and smooth curve without any pattern. Second, for the glass broken due to outer power, with the impact point as the center, the glass shows breakdown of radial type and the side shows breakdown of near-perpendicular type. The far the broken piece is from the impact point, the bigger the size is. The broken piece at the impact point is of long triangle type and the two long planes of the triangle shows semi-arc with the center of breakdown point and the other plane shows opposite pattern. Third, when glass that is damaged by outer power is heated, damaged forms and side patterns of the glass that is damaged by outer power are heated and disappeared.

The purpose of the study is to understand the unique characteristics of decoration style in traditional Javanese houses. Reviewing literature and visiting site were applied as the research method. Javanese House can be divided into three parts; roof, wall and floor. First, the roof of the traditional Javanese House is the most unique and important decorative element. The roofs are covered with roof-tiles and have clay carving ornaments on top. Usually there are no ceilings, just exposed to the oblique shape roof, which are made of wood to enable air ventilation. Joglo roof is the outstanding and representative roof type of Javanese houses. There is artistic and constructive roof structure named as tumpang sari in Joglo roof. The decoration on tumpang sari is the most colorful and symbolic ornaments. Secondly, the most unique element in the wall is the gebyok. Gebyok is made of wood and full of carved ornament, which has an artistic appearance, and also important function. The top part of doors are designed as perforated woodcarving, which give both aesthetic and ventilation purposes. Last, the stratified floor is begin with ground yard, then veranda that made from hardened clay, and main room constituted with a wood scaffold to provide air circulation and remove the humidity of the ground. The decorations of the column stand (umpak) are unique, where usually lotus flower is carved into black stone or lime stone. The outside of the buildings in Java Houses is not decorated by colors or symbols, whereas colors are only used in temples, pavilion or in royal housings. Instead they have carvings and decorations on important structural elements such as columns and beams inside. The ornaments and colors of decorations symbolize their god, ancestors and piece.

Culture and design change with time and what they have in common is that both develop in line with the era's living environments. Today, various life styles have emerged to cause changes in housing and living modes and we are in need of designs that can be commonly used in any place. Under the circumstances, furniture plays a role of medium that helps interactions between the human and the space and it has long been used in a variety of ways amid the change of the times. Soban, Korean traditional furniture, is a tool used in our real life and it is a piece of furniture that caters for both arts and functionality. It has been more of a living necessity and accordingly carried wisdom of experience for survival, rather than artificial beauty. Unlike other types of furniture, it is a practical tool designed in consideration of users. Therefore, this study aims to find traditional furniture's wisdom of experience in Soban, which tends to get neglected, and ensure its value as a modern design element, and to contribute to express and study the formative arts of Korean design so that a past living necessity of Soban can overcome its limitation of being floor-seating furniture and become more than an eating tool in it value.
