This thesis is based on the study of formativeness and versatility of Sarong. For the aim of the research, Sarongs were classified into two types: rectangular and tube, using its original form as the basis. These two types of Sarongs were divided into more detailed groups depending on the purposes of attire, such as skirts, dresses, and capes. To look into the formativeness and versatility of Sarong, the usage of wear and expression methods were observed based on these categories. The following results were found regarding the versatility of Sarong: First, Sarong has a wide degree of versatility in terms of usage. It can be worn as a skirt, a head scarf, a dress, a cape, or used as a carrier or even a sleeping bag, based on one's intention. The change of usage is often accompanied with the change of forms, as can be shown by the longyi of Myanmar, the tube type Sarong, which is used as briefs. Second, Sarong has a wide degree of versatility in terms of function. Variations of instrumental and expressive function of Sarong are observed simultaneously. The physical function sometimes coincides with the changes of usage as mentioned above. The way that Sarong's are expressed in different social situations changes depending on the wearer's social status, religion, or origin. So by looking at the way a Sarong is worn, others can tell if a person is going to social events such as festivals and weddings. Third, Sarong has a wide degree of versatility in terms of design. However, even if same usage and function is pursued, the design can be different based on an individual. This is because the external change of Sarong is affected by individuality or aesthetic sense of the wearer.

물 사용량 예측은 최적의 용수 공급 운영 방안을 수립하고 전력 소비량 절감을 위하여 꼭 필요한 과정이라고 할 수 있다. 그러나 수용가 단위의 물 사용량은 용도, 사용자의 패턴, 날씨 등의 다양한 요인으로 인해 변화하는 비선형적 특성을 지니고 있다. 따라서 본 연구에서는 비선형적인 수용가 단위의 물 사용량을 예측하기 위하여 다양한 기법들을 연계한 KWD 프레임워크를 제안하고자 하였다. 즉, 먼저 개별 수용가 마다 용도에 따른 유사한 패턴을 파악하기 위해 K-means (K) 군집분석을 수행하였고, 잡음성분을 제거함으로써 핵심적인 주기패턴을 파악하기 위해 Wavelet (W) 방법을 적용하였다. 또한 비선형적 특성을 학습시키기 위해 Deep learning (D) 알고리즘을 적용하였다. 그리고 기존의 선형 시계열 모형인 ARMA 모형과 비교하여 KWD 프레임워크의 성능을 분석하였다. 그 결과 제안된 모형의 상관성은 92%, ARMA 모형은 약 39%로 KWD 프레임워크가 2배 이상의 성능을 가지는 것으로 분석되었다. 따라서 본 연구에서 제안한 방법을 활용할 경우 정확한 물 사용량 예측이 가능해질 것이며, 상황에 따른 최적의 공급 방안을 수립할 수 있을 것이다.
