People counting has always been a method of interest for maximizing energy saving by identifying the congestion level or amount of use of a specific facility to efficiently manage the facility, or automatically implementing a power saving function by identifying the number of people entering and exiting a specific place such as a toilet. The method of counting people by image processing is very expensive and has the disadvantage of being severely affected by the surrounding environment of the lighting. In the case of the area sensor, there is a disadvantage of counting as one person when the number of people passes close with arms folded. In order to solve the existing method, which is expensive, affected by lighting, or inaccurate the number of people in certain cases, this paper proposes a new method of counting people using the principle of LiADAR. Accurate counting of the number of people entering the hospital will help manage hospital facilities, but it will also help to establish effective quarantine measures at the present time when Corona 19 is prevalent.

This study aimed at making a way of securing the access by using PCA. We got our result through using Box-Plot and PCA with the access data of the area of security level A~E at K(IPS)center. In order to perform PCA, We confirmed the extracted value of commonality has no problem in performing PCA because VIF is below 2.902. Based on this result, We classified people into Green-list, Blue-list, Red-list, and Black-list in a standard of security level with 1.453, as the eigen value of 1 main element, 1.283, as eigen value of 2 main elementm, 1.142, as the eigen value of 3 main element.

도서관 좌석 관리 시스템에 대한 연구 및 개발은 각 대학교 도서관뿐만이 아니라 기타 정부기관, 업체 등의 도서관에서 좀 더 효율적인 도서관 좌석 관리를 위해 이루어지고 있다. 도서관 좌석 관리를 위해 단말기를 통하여 지문이나 카드로 신분을 확인하는 등 다양한 수단을 활용하여 이용하는 사람들의 출입 및 좌석을 관리하고 있다. 하지만 현재 도서관 열람실은 특별한 좌석관리 시스템이 없으며 외부인의 출입이 제한되어있지 않아 학생들과 구분 없이 사용할 수 있다. 이러한 운영은 평소에는 문제가 되지 않으나 시험기간이 되면 수용할 수 있는 인원에 비해 사용 인원이 많고 또 제대로 된 좌석관리 시스템이 없어 항상 자리가 부족하게 된다. 이러한 문제를 근본적으로 해결하기 위해 본 논문에서는 도서관 좌석 관리 시스템에 카메라를 이용한 영상 처리 기법을 적용하여 열람실의 좌석 정보를 영상 처리를 이용하여 사용자에게 보여 줄 수 있는 무인 자동화 시스템을 제안하였다.

As a result of reenforcement of livestock industry licensing and livestock related vehicle registration system, pig farm are mandatory for setting stop bar before pig farm entrance and maintaining the records of inlet and outlet to and from pig farm. Also, the first step to the pig farm biosecurity is the control of entrance human, vehicles, animals and the related records including entrance and sterilization. In this study, the pig farm entrance control system using RFID technology and web-server system was developed. For human entrance, contact type RFID reading system(13.56MHz) was developed. And the 900MHz RFID system was used to detect vehicle entrance. The test result shows that system actuating, recognition, saving records to the web server was successful. Then, the full system of human entrance recording unit, vehicle entrance recording unit, entrance control system, human sterilizing booth containing a tablet for inputting visitor's record and sterilization record was tested. The records were wrote to web server DB through the data management web-program. Performance test shows the entrance control and data management in server was successfully operated.

The purpose of this paper is to investigate the effect of the smart phone camera on the company's employees or employees of partner companies, we want to block things in advance. In this paper, we propose a smart phone camera control system which is connected with the personnel access right which enables to share the photographed image of the authorized user and the data shot only within the enterprise. To this end, we have developed the installation status of smart phone control program (MCS: Mobile Camera Control System) of employees, employees and visitors of company, and experimented and analyzed whether the smart phone control program installed in the authorized area. In addition, when visitors visited the company, the effect of prevention of photograph shooting through smart phone camera and the cost of seal sticker attached to the smart phone camera lens part were reduced.

This study is to present an improvement of physical security system operation by survey on the install and operation of physical security system of 90 facilities. The level of CCTV operation is higher than Access Control system and Intrusion Detection System. But the level of maintenance and management of physical security system is low. The rate of install of X-ray Inspection device show the concern on material detection, although the rate is low. The level of install and operation for the Integration of physical security system is low, so integration of security personnel and security system is necessary for the effective operation. For reinforcement of access control management, security gate and preparing of some obstacles are required with RFID.

An information-oriented basis in today's society has been changing fast, and the desire for connectivity has caused an exponential growth in wireless communication and sensor network. Sensor networks using RFID, in particular, have led this trend due to the increasing exchange of data in Ubiquitous such as the home RF, access control system, U-Healthcare, and Logistics information Systems. Also, the RFID when it applies a technique, is able to raise the stability of shipping as controling the mobile course and an entrance and exit of the crews an well as previously preventing an accident from shipping. In this paper, we designed and implemented personnel control system using UHF-RFID in vessels which shows through host PC reading and writing tag.

IoT (Internet of Things) is connected to all things Internet-based people and things, things and objects that communicate information between said intelligent technologies and services. Shipping each of a variety of devices that act independently from each other, but, it is actively interlock with each other is not easy practically days. Ship it within the means of communication, the communication between the ship, the communication between ship and shore configuration, SAN (Ship Area Network), RFID/USN, broadband communications, satellite communications and IT technology to a variety of marine environments for the safe navigation the ship's safety management system for the configuration you want to discuss the plan.
