To evaluate the utilization suitability of solar radiation models, estimated solar radiation from 13 solar radiation models were verified by comparing with measured solar radiation at 5 study stations in South Korea. Furthermore, for the evaluation of evaporation estimates according to solar radiati...

T-Commerce란 무엇인가? | 이 같은 전자상거래업 성장 과정에서 우리나라의 전자상거래 기업체수는 2006년 2,260개에서 2016년1) M-Commerce란 Mobile(개인정보단말기)를 이용한 상거래를 말하며, 안전한 대금결제가 핵심적 기술로써 즉시성과 편리성을 특징으로 한다. T-Commerce란 TV와 상거래가 결합된 단어로 디지털방송 환경에서 리모컨을 이용하여 상품의 검색, 구매, 결제를 완료할 수 있는 서비스시스템을 일컫는다. 14,573개로 크게 증가하였고, 종사자수도 동비교년 13,556명에서 66,785명으로 290%나 급증하였다. | |
스마트폰을 이용한 모바일쇼핑이 증가하고 있는 이유는 무엇인가? | 이런 관점에서 고객은 ‘점포방문형 쇼핑’(이후, 오프라인쇼핑으로 부름)에 비해 온라인쇼핑을 더 선호할 것으로 보인다. 최근에는 이동통신 용량과 속도 증대와 스마트폰의 급속한 보급, 어플리케이션 발전 등으로 온라인쇼핑몰의 매출액 비교에서, 스마트폰을 이용한 모바일쇼핑이 컴퓨 터를 이용한 인터넷쇼핑을 추월하고 있다. 2) 이러한 소매 시장의 빠른 변화에 대처하기 위해 오프라인 쇼핑 사업의 대표적 업태인 백화점을 비롯한 대형 할인점, 슈퍼마켓에서도 온라인쇼핑을 보완하여 종래의 매출유지와 신규수요 창출을 통한 시장점유율 증대를 꾀하고 있다. | |
유통 환경의 변화에 대응하고자 소매업이 노력하고 있는 것은 무엇인가? | 1990년대 중반 이후 소매시장은 정보통신 인프 라의 구축과 매체기술의 발전, 신용카드 사용 확대, 택배물류시장 성장을 배경으로 발전하였다. 그 과정에서 소매업은 소비자의 경제성, 편의성을 우선적 으로 추구하면서 구매 과정에서 상품정보에 대한 비교, 검색 활동을 필수조건으로 행동하는 소비 트렌드 변화에 직면하고 있으며, 이러한 유통 환경의 변화에 대응하고자 가격경쟁력 증진과 상품차별화 실현, 효율적 유통경로 확보를 통한 매출증진, 고객서비스 향상을 위해 치열한 경영쇄신 노력에 경주하고 있다. |
