This study developed a user focused interface to improve a temperature regulation smart wear system controlled by a textile switch embedded on the outer surface. Designers need to investigate problems between design and consumers to enhance usability. Companies usually launch a final product where problems are resolved by repeated usability evaluation from the initial stage of product development. A textile switch was made all fabric for natural wear ability and designed for easy control and hands-free operation. Usability evaluation for textile switch design was conducted after reading manual without functioning. The survey selected five possibilities (metaphor, consistency, efficiency, flexibility, and aesthetic) from 10 heuristic evaluation assessment criteria of Nielsen(Feedback, metaphor, control, consistency, error prevention, efficiency, flexibility, aesthetic, recover form error, and help) to evaluate with a 5-point Likert-type rating scale restricted by 17 questions that collected specific opinions about user satisfaction. We randomly selected 20 general users to conduct the survey. A textile switch was made all fabric for natural wear ability and designed for easy control and hands-free operation.

We randomly selected 20 general users to conduct the survey. Textile switch is suitable for the interface of temperature regulation smart wear systems in terms of usability, because it synthetically presented high user satisfaction standards. We modify the final prototype based on usability problems selected through subjective evaluation.

최근의 다목적댐 운영은 기존의 홍수조절, 용수공급, 수력발전과 같은 수량뿐만이 아니라 수질, 생태환경 등 다양한 이해관계를 고려하도록 요구받고 있다. 본 연구의 목적은 주암조절지댐의 저온 심층수 방류로 인해 사회적 갈등이 있는 지역을 대상으로 수온을 조사하고, 수온변화 특성을 분석하는 것이다. 본 연구에서는 주암조절지댐, 하류하천, 순천만 지역에 대해 장기간에 걸쳐 수온을 모니터링 하였으며, 3차원 수치모형(EFDC)을 활용하여 방류량과 같은 다양한 외부 인자들을 고려하여 하류하천 및 순천만에서의 수온변화를 비교 분석하였다. 모니터링 및 수치모의 결과 댐의 저온 방류수 영향은 대체적으로 4월～9월 기간에 나타나는 것을 알 수 있었으며, 또한 댐 저온수 방류 영향이 방류시기, 방류수온, 방류량, 기상, 조위 등 다양한 인자에 의해 복잡한 형태로 변화한 것을 알 수 있었다. 본 연구의 결과는 댐의 저온수 방류로 인한 하류하천 및 연안지역 악영향을 최소화하기 위한 댐 운영 개선방안 수립시 기초자료로 활용될 수 있을 것으로 판단된다.
