To develop cool touch feeling fabrics for summer clothing material, it was manufactured several compositions of woven fabrics, having rayon multi-filament yarn (non-twisted) as warp and various kinds of yarn, such as viscose rayon multi-filament yarn (twisted), tencel$^{(R)}$ spun yarn, PET high absorbance quick dry filament yarn, and PET based rayon-like yarn, as weft. After preparing the fabrics, basic properties of the fabrics were investigated, such as air-permeability, tensile strength, absorption rate, drying rate, etc. Also, surface warm / cool sensations of the woven fabrics were assessed by Qmax Warm / Cool Touch Tester. It was observed that the fabrics composed of viscose rayon multi-filament yarn (warp) and PET high absorbance quick dry filament yarn (weft) showed excellent surface cool touch sensation-the highest Qmax value. This is because the fabric having flat shaped PET high absorbance quick dry filament shows the largest contact area with Qmax measuring plate. And, the fabric also showed superior high absorbance and quick dry property as expected. In addition, we treated phase change material (PCM) on the surface of the fabric composed of viscose rayon multi-filament yarn (warp) and PET high absorbance quick dry filament yarn(weft) to improve the cool touch feeling. However, the surface cool touch feeling was impaired by resin treated with PCM during the finishing process.

This study provides basic indices for the development of a pet dog's dummy. Surveys were conducted with 71 owners of small dogs weighing under 10kg as preliminary research for information on pet dogs, uses and complaints about their clothes and demographic information to investigate wearing conditions. We collected pictures of 30 products sold in 12 brands at home and abroad to analyze size, materials, and patterns and investigate the actual production conditions. The survey results on wearing conditions indicated that 'Maltese' was the breed most often raised in households. Dogs weighing 'between 3kg and 4kg' were most common. Dogs under five years of age took up 53.5%. Most of the clothes were 'S' size, followed by 'M' and 'L' Most responded, 'The overall size does not fit' as an inconvenience when worn for long. Second, most brands developed products in three sizes. The displayed details included neck and chest circumference, back length and dummy height. Cotton and artificial leather were used most often for the outer fabric, cotton for the internal filling along with wire and aluminum for some products to maintain shape and motions. Most dummies consisted of back+outer leg, belly, inner leg and sole. Sometimes, a composition line was added by the chest shape, and an incision was placed between the body and leg for breeds with thick legs. Most patterns had a composition line in the leg connected from the belly.

2018년에 발행된 반려동물 관련 산업 규모 추정 및 전망에 관한 논문에 따르면 2015년 기준 우리나라 반려동물 보유 가구중 26.9%가 30대 1인 가구이며, 부부로만 구성된 1세대 가구인 것이 확인되었다. 1인가구와 맞벌이 부부가 사회적으로 증가한 것과 관련하여, 반려동물이 원하지 않는 방치 시간의 급증과 훈련시간 부족이 문제가 된다고 판단된다. 본 논문은 레고마인드스톰을 이용한 반려동물의 훈련 및 관리를 위한 하드웨어 및 소프트웨어 제품 개발을 진행하였다. 레고마인드 스톰은 다양한 센서를 구비하였고, 쉬운 조립 및 비주얼 스크립팅을 통한 간단한 프로그래밍으로 반려동물을 훈련하거나 케어하는 장비를 제작 할 수 있다. 또한 자체 모듈화가 잘 되어있어, 새로운 장비로 전환 또한 쉬울 것으로 예상한다. 이 연구를 통해 반려동물시장 확대가 활발해지는 때 반려동물의 훈련과 관리에 도움이 되길 기대한다.

Recently, the automobile industry is developing as the demand for automo- biles increases due to industrial development and population growth. In addition, many studies are being conducted to reduce heat loss inside the automobiles in order to save energy inside the automobiles due to environmental regulations. In this study, alumina, nanosilicon, and aerogel, which are adiabatic materials, were filled in PET to manufacture yarn, identify physical and mechanical properties, and weave into fabric to confirm adiabatic performance. As the content of the adiabatic material increased, the tensile strength of the fibers filled with alumina and nanosilicon decreased greatly, and the adiabatic property slightly increased. The tensile strength of fibers filled with the aerogel decreased slightly, but the adiabatic properties were greatly increased. Therefore, it is considered to be due to the large volume fraction in the PET yarn due to the low density of the aerogel.

일련의 dimethylformamide (DMF) 기반 폴리우레탄은 메틸렌 디 페닐 디 이소시아네이트(MDI) 1,4-부탄 디올 및 바이오 폴리올(1,3-프로판 디올: B-POL)에 기초한 폴리 트리 메틸렌 에테르 글리콜/폴리 에스터 폴리올(1,4-부탄디올: H-PET)으로 부터 합성하였다. 본 연구에서는 바이오 폴리올(B-POL)/폴리에스터 폴리올(H-PET)의 조성이 폴리우레탄의 물성에 미치는 영향을 조사하였다. B-POL/H-PET 혼합물의 B-POL 함량이 증가할수록 폴리우레탄의 소프트 세그먼트의 유리전이온도(Tgs)와 인장 강도는 감소하는 반면, 파괴 신도 및 인열 강도는 증가하였다. 한편 합성된 DMF 기반 폴리우레탄을 이용하여 습식공정으로 인조피혁을 제조하였다. 인조피혁에 형성된 다공성 셀의 평균 크기 및 밀도(단위부피당 셀의 수)에 미치는 B-POL/H-PET 조성의 영향의 차이는 거의 없는 것을 알 수 있었다. 이러한 결과들로부터 바이오 폴리올 기반 폴리우레탄을 습식공정으로 제조되는 인조피혁용으로 사용하는데 별 문제가 없음을 알 수 있었다.
