Sericin 정착은 친수성 단백질인 세리신을 화학처리에 의하여 소수성으로 변화시켜 fibroin 에 밀착, 응고시켜 생사를 양모와 유사한 섬유로 변화시켜 제품의 다양화를 기할 목적으로 많이 행하여졌으며 이에 따른 증량효과도 크게 기대되어진다. 종래의 세리신 정착방법들은 생사의 제리신 정착외에 공업적으로 그 가치가 크게 인정되었던 견사, 생사 층 등에도 광범위하게 응용되어 많은 특허가 있는데 이들 정착방법을 대별하면 (1) Aldehyde 처리에 의한 세리신 정착 (2) Cr 감류처리에 의한 세리신 정착 (3) Epoxy 화합물의 처리에 의한 세리신 정착 (4) 합성수지 처리에 의한 세리신 정착등을 들 수 있겠으며 그 중에서도 특히 Aldehyde 에 의한 정착 (주로 formaldehyde 사용) 과 Cr 감류에 의한 정착이 가장 많이 행해진 경향을 보인다.

In this research, a woman matched to the average Korean standard size specification of 21-24 years of age was scanned using Cyberware. Rapidform 2004 was used to separate the body zone into fit zone, action zone and design zone, depending on the function of the lower body. Each divided body zone expanded radially using 'offset' by 1.60mm at the cross section of the waist, and 6.36mm at the hip level. Resultant ease values were 1cm and 4cm along the waistline and hipline (respectively), as recommended in previous research. 2C-AN program and Yuka CAD was used to develop a pant pattern from the enlarged 3D body surface blocks. A total of five pants were constructed using conventional fabrics for light weight formal pants. The appearance of the experimental pants were evaluated by five clothing-major evaluators using a questionnaire that consisted of 21 questions. In addition, functional aspects of the experimental pants were also evaluated by wearer while performing five postures for the measurement of ease of movement. It was found that, the method of regional offset and suggested 3D to 2D pattern development generate reasonably good pant patterns. Among the pattern block arrangements, the method B was evaluated as the best way to generate formal pants from the tight-fit pattern, which fit smoothly over the lower body for maintaining ease of movement.

The primary goal of this study was to provide a systematic methodology of utilizing 3D technology for tight-fit performance sportswear using information of skin deformation in various posture. Technical tools used in this study are Cyberware whole body scanner, RapidForm2004, 2C-AN 3D pattern development program, and YukaCAD. Analysis of the 3D skin deformation while knee joint was bent from $0^{\circ}$ to $60^{\circ}$ revealed that the length of dermatomes L4 was remained consistent during knee bending. Therefore, L4 was chosen as a major cutting line. To develop a highly ergonomic pattern, replicas of static and dynamic postures were developed and integrated using two methods, one is morphing method (Sqirlz Morph), and the other is AutoCAD. Experimental tight-fit garments called 'Derm-Mov Pattern' was designed using dematomes L4, L2, and inner line under knee and compared with four other patterns. As results, AutoCAD was appropriate as a integrating method of various postures. In wear test, 'Derm-Mov Pattern' was rated high (p < .001), in terms of pressure comfort especially around front crotch area. However, wear sensation was not signipicantly different in other area due to highly extensible property of materials. Pressure distribution was relatively even in these experimental garments.

본 논문은 윤곽 형상에 밀착된 임의 형상 마스터를 이용한 스키니 스머지 블렌딩 방법에 관한 것이다. 스머지 툴(smudge tool)은 Adobe Photoshop CS6에 내장된 대중적인 그래픽 툴로서 물감을 화폭 상에 문질러서 흐려지게 할 시에 이용된다. 그 효과는 지두화법과 매우 유사하다. 스머지 툴은 Adobe Photoshop CS6의 툴박스에서 스머지 아이콘을 선택한 다음에 화폭 위를 클릭한 후, 마우스 버튼을 누른 상태에서 번짐 효과를 주고 싶은 방향으로 끌어당김으로써 그 기능을 이용할 수 있다. 그러나 기존의 스머지 툴은 마스터 반경 내의 모든 화소값을 블렌딩시켜 결과 영상을 생성함에 따라 원하지 않는 부위의 화소마저도 변형시키는 단점이 있다. 이러한 단점을 해결하고자 본 논문에서는 임의 형상 마스터를 이용한 스키니 스머지 블렌딩 방법을 제안하고자 한다. 제안된 블렌딩 방법은 컬러 영상 분할에 통해 윤곽 형상에 밀착된 임의 형상 마스터를 추출함에 따라 배경에 관계없이 변형하고 싶은 부분에만 번짐 효과를 적용시킬 수 있는 장점이 있다.

This study develops tight-fitting torso patterns for performance garments by taking into account the skin deformation generated directly from a 3D scan during arm movements. The skin deformation caused during the arm movements was scanned after scanning the skin surface stamped with a circle. To create a torso pattern in response to skin deformation, the ratio and direction of the skin deformation were first measured and analyzed so that the 3D human body could be segmented. After translating, the 3D skin surface was segmented into 2D flat patterns, designing nude patterns and reducing them as well as tight-fitting shirts: the skin deformation segment shirts were made in response to the skin deformation. The features of the fabric deformation and the garment pressure were analyzed and evaluated. In comparison with a clothing construction segment shirt, the diameter of the skin deformation segment shirt was smaller as well the ratios of extension and reduction was less. The garment pressure of the skin deformation segment shirt was higher. The skin deformation segment shirt fitted more tightly compared to a clothing construction segment shirt as it covered the body more thoroughly and was as comfortable as the other shirts with less fabric deformation made as the body moved.

ME-ARE법에 의해 합성된 c-BN 박막의 초기성장층 및 이의 계면구조를 개선하고 밀착력을 향상 시키고자 후처리로서 질소이온을 주입$(PSII-N^+)$하였다. 이온 주입량이 c-BN 박막의 미세구조, 계면구조에 미치는 영향에 대하여 조사하였으며 이와 함께 박막의 경도 및 박리특성에 미치는 효과를 고찰하였다. 질소이온 주입시 약 $5.0{\times}10_15atoms/cm^2$ 이상의 주입량에서부터 IR스펙트럼의 변화가 보이기 시작하였으며 $5.0{\times}10_16atoms/cm^2$ 이상의 주입량 이상에서부터 급격한 c-BN$c-BN{\to}h-BN$상전환이 일어났다. HRTEM관찰 결과, 이온주입에 의해 $sp^2$ 결합을 하고 있는 취약한 초기성장층의 결정구조 개선을 확인할 수 있었으며 이온주입된 박막의 경도 및 박리거동을 비교하여 이온주입 및 주입량에 따른 경도 및 박리 상관관계를 설명하였다.

A Holter monitor is used for ECG monitoring of ambulatory daily life in hospital. However, the use of this apparatus causes skin allergies and discomfort in patients because of the attachment gel and tapes used to attach disposable electrodes to the skin. In this study, the development of tight-fitting clothing connected to a portable Holter monitor was proposed. In addition, the use of conductive fabrics as electrodes was proposed; this will enable the use of garments in u-health care for measuring ECG signals. The male subjects were university students in the ages of 20 to 24. Subjective wear sensations of the experimental garments were rated using seven Likert scales. A Likert type scale was used for the evaluation and a 7 point score indicates that it provided the best fit as a tight-fitting upper clothing. Clothing pressure was measured using an air-pack-type pressure sensor (model AMI 3037-2) at 4 locations (the conductive fabric electrode) As results, a male basic sloper for upper clothing was developed and that pattern was manipulated to the tight fit pattern by considering the reduction rate of the percentage stretch in the fabric. The developed tight-fitting garment was superior in terms of subjective sensation and 6t. The mean pressure of the garment with reduction rates of 40% in width and of 50% in length was 8.45gf/$cm^2$. A conductive fabric electrode was developed by considering the sewing method and the developed electrode was detected well. The ECG data were recorded for 13 hr 19 min 44 sec and the artifacts in the ECG signals were recorded for 9 hr 3 min 46 sec (total time: 22 hr 23 min 23 sec). The artifacts data were obtained during heavy activities.

This research studied how to develop tight upper sportswear from 3D scan data considering fabric stretch property. Subjects were five Korean men of average figure in their 20's. Scanning was done for ten postures via vitus smart/pro(Techmath LTD). Analyzing from 3D scan data, more than 70% of the upper body surface showed surface change rate under 20%. It was shoulder and under arm side part that showed most noticeable body surface change when moving. A parametric model with convex surface was generated and flattened onto the plane, resulting 2D pattern. The error rate occurring in the process of 3D to 2D conversion was 0.2% for outline and 0.13% for area, respectively. Thirteen kinds of stretchable fabrics in the market were collected for this study. Stretch property was in the range of 16.0~58.2% for wale direction; 23.1~78.4% for course. Based on wear trial test, four fabrics were chosen for making the 1st experimental garment and finally one fabric was chosen for the 2nd one, which was developed applying 4 kinds of crosswise reduction rate on 2D pattern: 0, 5, 10, and 15%. Through wear trial test and garment pressure measurement, experimental garment applied with 10% pattern reduction rate was evaluated as most comfortable and considerable.
