This research developed a smart girdle for adult women in their 20's that has an inserted carbon weaving heater to help with relief from coldness and abdominal disease through the thermal insulation effect. A pocket of powernet fabric was attached to the inside of the girdle for the easy insertion and separation of the heating device, while the heating device was fixed to a mesh material by cotton yarn and was wrapped with elastic lining material to prevent the mechanical devices from being exposed. A set of 3 hooks was attached to the center of the back of the heating device in consideration of convenience and mobility. Whereas the switch was inserted into around the right waistband, and the battery into the inner pocket around the waist, to integrate the heating device with the girdle. The satisfaction and usability of the fabricated smart girdle was verified by having research participants wear it to evaluate the appearance change caused by the device, the inconvenience of wearing/unwearing, mobility, and the satisfactory functionality of the device. As a result, the grand mean was evaluated to be high, with appearance (4.19), mobility (4.17), and functionality (4.51) being higher than 4.00; which indicates that the heat generation function of the smart girdle is effective. It may be said that such collection and analysis of data that reflect users' opinions have value and significance in that they can be grafted onto future research on new technology as well as they contribute to taking a step forward in the rapidly increasing research of smart clothing, with the new-type clothing equipped with new function.

This study is basic material for development of a smart girdle. Through the intentionally sampling of 313 consumers from teenagers to the forties who have experienced wearing girdles, lifestyles on consumer's age, attitude to health, favor of warm functional girdle, and possibility to acceptance were surveyed and analyzed by questionnaire. The result of the study are summarized as followed. 1. Analysis about lifestyle with warmth and attitude to health showed that subjects in their thirties and forties have higher than teenagers and the twenties in frequency of distribution. This means people are tend to have more attention to warmth and health as they grow older. 2. In result about analysis of characteristic of wearing girdle, subjects were prefer girdle made of cotton which have superior permeability and hygroscopic property. The reason that wearing girdle is to complement of weak points of body somatotype in the thirties and forties and feel the stability during menstrual period in the twenties and teenagers. The time zone of putting on girdle is mainly winter while one is out wearing one-piece or skirt. 3. When surveyed about the preference to functional warmth girdle and possibility to acceptance, the results were that the subjects in their thirties were first, forty something was second, followed by subjects in their twenties, teenagers. It was shown that over 60% subjects were highly distributed. With regard to necessity of functional warmth girdle, every age groups were shown over 3.6 at average. This result was inferred that subjects had positive possibility to acceptance about functional warmth smart girdle.

The aim of this study was to use a 3D human body scanner to analyze the cross section of different body parts when a girdle is worn. Two types of girdles were selected as experimental garments: a standard type girdle (Garment A) and a high-waist type girdle (Garment B). Their sizes were 88 (S) and 94 (M). Ten female subjects in their twenties who wear girdles sizes 88 (S) and 94 (M) participated the experiment. Their bodies were scanned three times with the 3D human body scanner, before and after wearing experimental girdles. The data were collected by overlapping the cross sections of the 3D scanned body shape data. The space length was measured from the overlapped cross sections. The results show that human body silhouette are changed after wearing the compression type garments and the amount and place of the body change is different by style of garments. First, the waist girth shape became rounder. Second, there was a definite difference in space amount at abdomen girth between two types of girdle. The abdomen area was pushed toward the front after wearing the standard type girdle (A). The high-waist type girdle (B) pushed abdomen area toward the back. Third, there was clear difference at the hip area after wearing two types of girdle. The hip area pushed toward the front with the standard type girdle (A) and pushed toward the back with the high-waist type girdle (B).

필드이온빔(FIB) 가공기를 써서 초고강도의 벌크다이아몬드를 가공하기 위해 이온 소오스의 종류와 가공 조건에 따른 나노급 미세 선폭의 최적조건을 알아보고 이에 근거한 2차원적인 텍스트의 가공과 3차원적인 박막요소의 가공을 시도하였다. 다이아몬드 기판과 실리콘 기판을 Ga과 $H_2O$ 소오스를 이용하는 FIB를 써서 30 kV 빔 전류를 10 pA $\sim$ 5 nA로 변화시키면서 패터닝하고 이때 각각 20 ${\mu}m$ 길이로 생성되는 선형 패턴의 선폭, 깊이, 에치속도, 에치형상, 깊이선폭비 (aspect ratio)를 확인하였다. 다이아몬드도 실리콘 기판과 마찬가지로 나노급 패턴의 형성이 가능하였다. $H_2O$ 소오스를 채용한 경우가 에치 깊이가 2배 정도 증가하였으며 동일한 가공 조건에서는 실리콘에 비해 다이아몬드의 에치 선폭이 감소는 경향이 있었다. 특히 다이아몬드는 절연성 때문에 차지가 축적되어 가공 중 이온빔이 불안정해지는 문제가 있었으나 차지 중화 모드를 이용하여 성공적으로 sub-100 nm급 선폭의 미세 가공이 가능하였다. 확인된 선폭가공 조건에 근거하여 2차원적으로 0.3carat의 보석용 다이아몬드의 거들부에 300여개의 글자를 FIB를 활용하여 선폭 240 nm정도로 명확히 기록하는 것이 가능하였다. $Ga^+$이온과 30 eV-30 pA로 조건에서 비교적 넓은 선폭과 Z축 depth 고정범위에서 많은 개인정보의 기록이 영구적으로 가능하였으며 전자현미경으로 재생이 가능하였다. 3차원적으로 두께 $1{\mu}m$의 박막요소를 FIB가공과 백금 용접으로 떼어낸 후 FIB가공으로 두께가 100 nm가 되도록 한 후 투과전자현미경을 이용하여 성분 분석을 하는 것이 성공적으로 수행될 수 있었다.
