This study divided hairpiece-related technologies into three categories: Materials, Structure, Hair Extensions. Then, it investigated the current patent application trends in the above technologies and attempted to determine what aspects should be focused on in terms of the growth potential of hairpiece-related technologies and future technologies. A hairpiece is used to cover a specific balding area resulting from innate factors such as heredity or acquired traits including disease or accident. It is also used to make short hair look longer. Recently, as the rates of hair loss caused by stress increase, there has been a rising demand for hairpieces that can quickly and conveniently cover a balding region as well as satisfy people's aesthetic needs through diverse hairstyling. Even though patents have been applied evenly across hairpiece technology fields, patent activity has declined since 2010 was confirmed. Therefore, this study targets the facilitation and expansion of the hairpiece technology market by suggesting desirable R&D directions for future hairpiece-related technologies after analyzing current hairpiece patent trends.

The costume culture of ladies in late Goryeo is an important and rare source for cultural fashion souvenir design. This study investigates the historical costume design sources of late Goryeo to suggest high quality traditional and practical ornament souvenir designs for female dolls as well as examples of coordination with doll costumes. The costume culture of late Goryeo contained golden Buddhism and a revival of $12^{th}$ century Goryeo costume characteristic after the period of Mongolian influences from the Yuan. The main sources for doll ornament designs are $14^{th}$ century Buddhist paintings, a few ornament relics of Goryeo, ancient literature, and portraits of ladies in the $14^{th}$ century that originated from five doll's traditional ornaments (lotus hairpin, cloud-shaped hairpin, Buddhist flower hair ornament, vase-shaped Binyeo, and bell of animalhuman face) and three wig designs (wigs from Buddhist paintings and portraits, and hairpiece) with bleached gilding silver, silk, various gemstones and synthetic hair. These doll ornament and wig designs imply the symbol of Buddhism, exorcism, and costume culture of $14^{th}$ century Goryeo ladies that can be matched with two doll gowns, half-sleeved jacket, skirt, two Jogoris, apron, under trousers as formal, semi-formal, and town-wear according to the T.P.O of late Goryeo; in addition, five ornaments can be used as owner's ornaments. The partial changing colors and materials due to the characteristics of doll ornament goods as well as better communication between researcher and constructor remain to be improved.
