New types of armor, including space armor, multiple-layered armor, composite armor and modular armor have been successfully developed and installed on the armored vehicles of several nations. The protective capability of armor against penetration is established. Of developed composite armor, space armor has a simple structure and is easy to produce and can be produced at low cost. This study uses the finite element package DYTRAN and the pre and post processor PNTRAN to elucidate the ballistic resistance and penetration of space armor. Factors such as armor thickness, space between armors and projectile profile are considered. A technique for simulating the protection afforded by armor and supporting the design of space armor is developed.

This study helps develop a cool body armor that maintains a tight-fit configuration to the body surface and evaluates the performance of newly developed body armor in a wear test. Three types of body armor were used for evaluation. One was a tight fitting body armor that was constructed to improve the degree of fit and ease of movement for Korean soldier using 3D technology. Another was ventilating body armor with attached spacers on the shoulder to reduce the thermal stress on the soldier. The third was a prevailing body armor produced by a Korean body armor company. In order to evaluate the performance of the body armor, a human wear test, a thermal mannequin test, and computational fluid dynamics (CFD) were executed. Five subjects participated in the wear test. Subjective wear sensation, total amount of sweat and dynamic change of clothing microclimate were observed during and after exercise on a treadmill; subsequently, it was found that subjects rated tight fitting body armor and ventilating body armor lighter, drier, and easier to move than the conventional body armor (p<.05). Total amount of sweat was the least in the case of ventilating body armor. The thermal resistance and vapor resistance of the ventilating body armor were improved remarkably. In addition, the skin temperature of the ventilating body armor with spacers was lower than the tight fitting body armor by at least $1^{\circ}C$ in the CFD result. It is noted that thermal-wet comfort of the 3D body armor with ventilating feature is superior to the conventional body armor, especially when the ventilating channel is not closed due to a backpack.

This research is about the reproduction of Baekje's armor-lamellar made for the Hanseong Baekje Museum exhibition. The purpose of the research are as follows. First, to categorize Baekje armor by type based on ancient documents and the excavated relics. Second, to reproduce categorized armor that provide a visual work for use in diverse areas. Baekje armor can be examined through the ancient records and several excavated relics. The results of the research are as follows. First, Baekje armor can be categorized into four types by material: 1) brass 2) iron 3) leather 4) bone. The can also be categorized into three types by finishing a) Hyeongnyubongnyun type (the leather skin interweaves with the lamellar armor method) b) Hyeokpobongnyun type (the method which wraps around the edges of leather skin) c) leather cloth added to clothe type. Second, we reproduced metal armor, iron armor and leather armor using brass, iron and leather (but not bone). Each type of armor were made life-size for exhibition purposes. We used Hyeongnyubongnyun method, Hyeokpobongnyung method and leather cloth; in addition, reproductions were made based on the Yangdang method that connected the front and the back from both sides of the shoulders so it can be open and close at the side part.

The purpose of this study was to identify the structure and characteristics for the reproduction of the armor in the Unified Silla period, and then reproduce and utilize it as a cultural content. In the armor reproduction project excavated from Jaemaejeong, Gyeongju. Jaemaejeong armor is consisting of Singap (身甲, body armor), Sanggap (裳甲, hip armor), and Sangbakgap (上膊甲, upper arm armor) at the time of excavation. Unlike the armor of the Three Kingdoms period, Singap and Sanggap are separated. Singap is Yangdangsik (裲襠式, side opening method) and Gyunggap (頸甲, gorget) was not unearthed, Sangbakgap was divided into a part that protects the left and right upper arms and a part that protects the chest, so that the unexcavated head and neck cover of the helmet can be protected to the shoulder. In addition, in the case of Chalgap (札甲, lamellar armor), the Oejungsik (外重式, folded from outside to inside) is mainly used, but it is peculiar that Naejungsik (內重式, folded from inside to outside) is used in Sangbakgap of Jaemaejeong armor. It is presumed that this was used as a method to ensure that the armor were closely attached to the human body. In order to design with the parade armor of Gochwidae in Gyeongju based on the reproduced Jaemaejeong armor, the designer's imagination and historical work of the times were involved due to the characteristics of performance costumes. Reproduced armor as a cultural content should be considered indispensable to simplify and lighten clothing suitable for performances based on the excavated historical armor.

The study researched the characteristic of helmet and armor reflecting Joseon Dynasty by focusing on the helmet and armor appearing in dramas, the Tear of Dragon and King Sejong, whose common point is the historical background, the early Joseon Dynasty, among the historical dramas, which are manufactured on the basis of historical person or age. First, the helmet and armor appearing in historical drama was reproduced on the basis of historical record depending on age. In the early Joseon Dynasty, helmet was classified into cheomju and wonju and armor was classified into chalgap, swaejagap, gyeongbeongap, dujeonggap and dudumigap. In drama, the Tear of Dragon and King Sejong, for helmet, cheomju and wonju were used and for armor, chalgap, dujeonggap and dudumigap, whose type and manufacture method were similar to that of historical record, were reproduced. Second, the helmet and armor appearing in historical drama searched for function. In drama, the Tear of Dragon, rather than heavy iron, plastic and textile were used and the metal scale inside armor was removed. In drama, King Sejong, the weight of armor was decreased by removing the metal scale inside armor and easy wearing was secured by using velcro. Third, the helmet and armor appearing in historical drama expressed various dramatic interpretations. In drama, the Tear of Dragon, the same color as that of armor was adopted for helmet to provide stable and unified feeling. Visually splendid display was added to armor by matching powerful prime color and glossy metal. In drama, King Sejong, modem sense was added to helmet and armor by actively using pastel color reflecting modem fashion.

The purpose of this study was to know how helmet and armor was reinterpreted in historical play by considering general concept and type of old helmet and armor from the aspect of costume history and comparing the helmet and armor types of TV historical plays, Yeongaesomun and Taewangsasingi, whose historical backgrounds were based on the age of Goguryeo. The helmet and armor type shown in Yeongaesomun was reinterpreted as the one, which is close to historical investigation, by reappearing lamellar armor and jongjangpanju(helmet made of slim, long plate) shown in Goguryeo wall painting. The helmet and armor type shown in Taewangsasingi expresses fantastic helmet and armor by adding fantastic factor regardless of historical investigation. The study result reveals that there are several common characteristic factors between the helmet and armors of two historical plays. First, there was a classification in the display of character and story. The helmet and armor type shown in Yeongaesomun classified color and detail design depending on lamellar armor or character. In Taewangsasingi, the helmet and armor was manufactured depending on character's nature and the chain armors, which are lighter than existing helmet and armors, were usual. Second, they escaped from the historical investigation about traditional helmet and armor. In Yeongaesomun, myeonggwangae(a type of armor), which might be popular, was not expressed and Taewangsasingi is free from an imperative idea of historical investigation by manufacturing helmet and armor referring to that of ancient Rome age. The modern sense was reflected to increase dramatic effect. The helmet and armor of Yeongaesomun provides modern feeling by using stainless steel material and modern color arrangement and that of Taewangsasingi is designed in modern, splendid way as it aimed at game development from the planning step.

The National Museum of Korea conducted conservation treatmenton the armor in its collection for the purposes of public display and appropriate preservation. This was preceded by a literature study on the types and features of the armor in order to collect basic data for secure and accurate conservation treatment. The literature study found that during the Joseon dynasty, armor was named in reflection of precise details including the color, material, status of the wearer, and even the certain parts of a suit of armor. In general, the name of armor includes the details in the order of color, underlying textile, and scale material (e.g., iron, leather). The former part of the name presents the features of the garment and the latter part refers to the material of the scales or the status of the wearer. The study also found that main materials used in armor include textiles, leather, and metal, and armor can be classified by the materials of the scales-e.g., metal armor (鐵甲), leather armor (皮甲), paper armor (紙甲), paper-and-fabric armor (淹心甲), silk armor (緞甲). Joseon-period armor can also be classified into four types according to its structure and the method of wearing, and overcoat(袍)-style armor was the most widely used in the period following the Japanese Invasion of Joseon (1592-1598) through the late nineteenth~early twentieth century. Overcoat-style armor was commonly worn by infantry, and the four examples of armor with leather scales at the National Museum of Korea belong to this category.

Due to the severe damages, it is very difficult to fathom out the original shape of the armor of Seong-ryong Ryu(1542-1607) right now. Ryu was a distinguished scholar official of his period, and his remaining armor has been designated as a National Treasure No. 460. This is a study of the types of the used scales, their positions used, the methods of their connections, and their hemmings, to figure out the original process of producing the armor. Based upon the research results, the remaining pieces of the armor are restored according to the discovered contemporary procedure of the armor. Then hypotheses are proposed for the three kinds of armor made up of long pieces, and three kinds of the armor of short pieces, and problems of the proposed hypotheses are considered for further studies. Hopefully this kind of approach shall serve as a ground stone for the better restorations of the scale armors of Joseon period in the future.
