The re-analysis on the stable weight of the concrete armor unit (CAU) at the roundhead and the suggestion of the covering range at the roundhead with the increased weight of CAU were conducted. Tetrapods were applied to the tests and the three dimensional hydraulic tests were performed. The test results for the stable weight at the roundhead area were similar to the guides from Korean Design Standard for Harbour and Fishery Port (MOF, 2014) and Coastal Engineering Manual (USACE, 2005). The investigation of covering range at the roundhead of rubble mound structures armoured with Tetrapods was suggested that the length of five times of the design wave height from the tip of the superstructure was needed and appropriate. Both sides of the superstructure should be covered with increasing weighted CAU to satisfy the stability at roundhead area.

Development of the reliability-based design program in the GUI environment is inadequate for engineers familiar with the deterministic design to deal with the international design criterion based on the probabilistic design. In this study, the design program based on the GUI environment is developed in order to more efficiently input the design factor and more easily carry out the design works. The GUI environment is the GUIDE (Graphic User Interface Development Environment) tool supported by the latest MATALB version 7.1. In order to test the model reliability, the probabilities of failure (POF) on the breakwater armor block (AB) and gravity quay-wall (QW) in the sliding mode are computed using the model in the Level II and Level III. The POF are 55.4~55.7% for breakwater AB and 0.0006~0.0007% for gravity QW. A non-GUI environment program results of the POF are 55.6% for breakwater AB and 0.0018% for gravity QW. In comparison, the POF difference is negligible for breakwater AB because the exact input design parameters are available, whereas the large POF difference, but within the same order, for gravity QW can be explained by the difference of the input design factors because of the poor input data information.

This study proposes an optimal design for a robotic welding system for a high-strength steel armor plate. In order to identify the welding defect parameters, we analyzed the 4M (man, machine, materials, method) characteristics diagram, as well as a cause and effect matrix, to improve the productivity and quality of welding defects. From these analyses, we designed optimal welding conditions and carried out welding tests -- such as mechanical testing and macro structure tests - with positive results. We determined that it was possible to obtain a quality similar to manual welding with our robotic welding system. In the future, we expect that the system will be used as inspiration for future welding system designs.

One of the representative local cultures in Gyeongnam is Gaya culture. This research aim s to develop fashion cultural goods design applying Gaya relics. Based on the study on cu ltural character, formative characteristics of relics, and questionnaire survey on cultural reco gnition and fashion cultural goods purchasing status of Gaya, the plan of Gaya fashion cul tural goods design was made and progressed. To develop design pattern, TexPro Design CAD was used. As to selection of relics to extract motif, Mounted vessel in the shape of warrior on horseback, Chariot wheel-shaped Pottery, Armor and Shield were selected. The main concept of design was 'Timeless Images of Gaya' to re-illuminate a long forgotten p eriod of Gaya, and to create modernization image of ancient period into modern living. By using oring image scale of IRI C or Lab, the 4 main themes of 'Timeless Images of Gaya' including 'Romantic Gaya', 'Dynamic Gaya', 'E -friendly Gaya', 'Modern Gaya' were constructed. According to the 4 themes, basic pattern, repeating pattern, application patter n were developed. And applied cases were developed to seek reality of design in the fashi on cultural goods. Also web page was constructed to develop educational and industrial accessibility and utilization in collaboration with design patterns and fashion cultural goods ap plying cases.

Although the rubble mound breakwaters in Korea have been damaged by typhoons almost every year, quantification of erosion of armor block have seldomly been made. In this paper, the damage of armor units is standardized by the relative damage. In the case where the number of damaged units is reported, it is divided by the total number of units to calculate the relative damage. In the case where the rehabilitation cost is reported, the relative damage is calculated by using its relationship with the present value of the past rehabilitation cost. The relative damage is shown to have strong correlations with the typhoon parameters such as nearest central air pressure and maximum wind speed at each site. On the other hand, the existing numerical methods for calculating the cumulative damage are compared with hydraulic model tests. The method of Melby and Kobayashi (1998) is shown to give a reasonable result, and it is used to calculate the relative damage, which is compared with the measured damage. A good agreement is shown for the East Breakwater of Yeosu Harbor, while poor agreement is shown for other breakwaters. The poor agreement may be because waves of larger height than the design height occurred due to strong typhoons associated with climate change so that the relative damage increased during the last several decades.

Online game digital hanbok has an aesthetic value in a digital culture and is useful for developing a digital hanbok design for online games as well as other industries. This thesis analyzes its attire and design composition elements to design a 3D digital hanbok by utilizing its formative characteristics. The literature review defines them as transmutability, virtuality, fictionality, reality and playfulness based on the characteristics of digital media, late digital generation and online games. We analyzed 471 images from 50 online games. Sonmaep was used for making 3D digital hanboks. Its attire was grouped into jogori pants, jogori chima, po and armor. Its design composition elements were classified as pleat, layering mu or hemline, mu sub gyeopmagi mitbadae, vent, git dongjung and decoration elements. The results feature 8 digital hanbok designs. Reality designs are replicas of jogori daegugo for men and po for women in the period of the Three States. Virtuality designs are slightly changed shapes of yoseoncheolrik for men and white jogori yellow chima for women in the Koryo Dynasty. Fictionality designs are casual fusion armors for men and women as a hyperbolic form. Playfulness designs are doll costumes for men and jogori chima for women as a kitsch and childish style. The concept of online game digital hanbok escapes from conceptual limitations of traditional hanboks. This result can be used for designing digital hanbok contents in various industrial parts.

In picture bible, the picture is helpful for showing story more vividly and specifically and it is helpful for finding the meaning of bible hidden behind familiarity. It plays the role of the most powerful testimony and expression, with which human provides himself. The purpose of study was to grasp the relation among historical background of the middle age, human's characteristic and symbolic color by considering the fact that the costume expressed in Maciejowski Bible, which is a picture bible of the middle age and observing type, color and decoration of costume. Among 46 folios organizing Maciejowski Bible, 129 pictures explaining the Book of Genesis, the Book of Exodus, the Book of Leviticus, the Book of Numbers, the Book of Deuteronomy, the Book of Joshua and the Book of Judges, which belong to the former 400 years of the old Testament, were analyzed for people's costumes. The pictures shown in Maciejowski Bible portrays object, costume and behavior on the background of France of the 13th century so we can find out the precious natures of middle age's costume, weapon and armor. Especially, the portrait about finger armor of chain mail attached in hauberk becomes the outstanding evidence that can encroach the discussion over whether it was used in the end of 1300s. Regarding costumes of main characters, they wore chemise and braies as underwear, wore tunic or cotte having various lengths from the length reaching knee to the length reaching 8round as basic costume and wore mantle with different-colored lining and hose with various colors. In the war picture, we can see hauberk made with chain mail and cyclas with long slit, which was worn over hauberk, barrel helmet, norman helmet and steel school cap. Regarding cap. man usually wore coif, beret, shade-shaped cap, straw hat and woman wore the decoration using veil and hairlace and used the method to wrap whole hair with net. As the colors used in the costume of the picture bible, scarlet, blue, green and brown were usually used in order. They usually wore costumes decorated splendidly with the colors haying hish brightness and chroma.

The purpose of this paper is to investigate the changing fashion image of the glossy materials including metal, leather, vinyl, latex, plastic etc. from 1960's to the present. Glossy materials used in the second half of the 20th century showed a restricted image combined with a specific social circumstance. They expressed a reflection of young and future-oriented space period of 1960s. Many designers like Paco Rabanne and Andre Courreges were concerned with the fashion of space age and expressed that image with leather and synthetic materials including silver leather, metal chain armor, and plastic appeared as the keynote of fashion. In 1970's, glossy material was the symbol of avant-garde and rebellious attitude by the punk fashion. They maximized glamourous look of 1980s, and cyber look with an expectation for a new millenium of 1990s. On the other side, glossy materials seem to be used as a source of various inspiration of fashion designer in the 21st century. Also, some of the past images, for example space look and glamourous look, are revived in the 21 st century by the form of modified design.
