Abstract: 본 발명은 숙박업소의 출입자 관리 시스템에 관한 것으로서, 좀더 자세히 설명하면 숙박업소의 객실을 이용하는 이용자의 사생활 보호를 위하여 출입하는 사람들 간의 접촉을 피하도록 유도하여 편의성과 안전성을 제공해 주는 객실의 출입 관리 시스템에 관한 것이다. 
     일반적으로 숙박업소는 소정의 이용료를 받고 객실을 대여해 주는 업을 하는 호텔, 모텔, 여관등을 의미하며, 이들 숙박업소는 대부분 객실과 주차장이 별도로 분리 구획되어 있고, 또한 사용자가 객실을 이용하기 위해서는 안내데스크의 객실안내자나 숙박시설 내의 관리 인력의 도움을 받아 주차 내지 숙박을 하도록 되어져 있다. 
     그리고 이러한 숙박업소는 이용자가 입실시 또는 퇴실시 객실안내자나 숙박시설 내의 관리인력의 도움을 받기 위해 안내데스크를 방문하게 되면서 입출입하는 사람들과 접촉하게 됨에 따라, 사업상 비밀스런 계약을 위해 숙박업소를 방문한 이용자나 개인 사생활을 위해 방문한 이용자들의 정보가 타인에게 노출되게 된다. 
     따라서 최근에는 상기 숙박업소를 이용하는 이용자의 편의성과 이용자의 사생활 보호를 위하여, 숙박업소에 단말기를 설치하고 이 단말기를 통해 각각의 객실 이용 가능여부 및 객실 내부 상태가 표시되도록 하는 동시에 객실 이용 선택시 해당 요금을 수납하면 객실 안내 및 열쇠가 주어지도록 하여 별도의 관리자 없이 이용할 수 있는 무인 관리 시스템이 발명되었다. 
     그러나 이러한 무인 관리 시스템 역시 공동으로 사용하는 복도와 엘레베이터를 중심으로 객실을 이동하기 때문에 입실과 퇴실을 요망하는 이용자들 간이 접촉으로 인해 개인의 사생활이 노출되는 문제점이 있다. 
     따라서 본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 그 목적은 숙박업소 이용시 입실과 퇴실을 요망하는 이용자들과 입출입하는 사람들 간의 접촉을 최대한 방지하여 개인 사생활을 보호하고자 하는 것이다.

Abstract: An optical laminate and an LC panel using the same are provided to suppress change of a retardation value of a positive C plate under high temperature and humidity by providing an adhesion enhancement layer between a retardation layer and an adhesive layer. An optical laminate(100) comprises the following sequentially. A first retardation layer(10) has a refractive index profile of nx>ny=nz. A second retardation layer(20) has a refractive index profile of nz>nx=ny. An adhesion enhancement layer(30) contains polyethyleneimine as a main component. An adhesive layer(40) is included in a side of the adhesion enhancement layer where the second retardation layer is not provided.
