현대사회에서 고객으로 대표되는 사용자와 기업으로 대표되는 공급자간의 관계는 복잡하고도 어려운 면면을 보여주고 있으며 그러한 면에서 공급자 측면에서 신규고객의 확보보다는 기 확보하고 있는 고객과의 관계유지가 더 어 렵고 중요한 기업생존의 요건으로 부각이 되어왔다. 이런 측면에서 공급자가 기존고객을 확실히 효과적으로 관리할 필 요성 뿐 아니라 기존 데이터를 바탕으로 신규고객을 창출할 수 있는 방법으로 CRM은 그 중요성을 지닌다. 따라서, 본 논문에서는 고객관리, 업무관리, 영업, 마케팅, 서비스 관리가 통합된 진보된 CRM 환경을 제공하여 중소기업이 진행이 일원화된 업무환경에서 인력대비 큰 효율을 올릴 수 있는 업무기반을 제공해 주며, 원격 고객관리 프로그램을 제공하 여 원격제어, 음성 및 화상채팅을 이용 고객에게 기업의 다양한 서비스 업무와 다양한 제품 설명 및 A/S를 제공할 수 있는 원격 서비스 기반의 통합 CRM 솔루션을 구현하였다.

In modern society, the relationship between users represented by customers and suppliers represented by companies is complex and difficult. In this regard, it has become more difficult and important to survive as a company to maintain relationships with customers, rather than securing new customers on the supplier side. In this respect, CRM is of importance as a way for suppliers to create new customers based on existing data, as well as the need to be more effective in managing existing customers. Therefore, in this paper, we conducted research to provide an advanced CRM environment that integrates customer management, business management, sales, marketing, and service management. We have designed a system that provides a business base for small and medium enterprises to achieve greater efficiency compared to the workforce in a unified work environment and provides a remote customer management program. Through this, we have implemented an integrated CRM solution based on remote service that can provide various business services and various product descriptions and after sales service to customers using remote control, voice and video chat.

As a decrease in labor became a serious issue in the manufacturing industry, smart factory technology, which combines IT and the manufacturing business, began to attract attention as a solution. In this study, we have designed and implemented a real-time remote management system for smart factories, which is connected to an IoT sensor and gateway, for plastic manufacturing plants. By implementing the REST API in which an IoT sensor and smart gateway can communicate, the system enabled the data measured from the IoT sensor and equipment status data to the real-time monitoring system through the gateway. Also, a web-based management dashboard enabled remote monitoring and control of the equipment and raw material processing status. A comparative analysis experiment was conducted on the suggested system for the difference in processing speed based on equipment and measurement data number change. The experiment confirmed that saving equipment measurement data using cache mechanisim offered faster processing speed. Through the result our works can provide the basic framework to factory which need implement remote management system.

Today, most of elevators have an emergency call facility for emergency situations. However, if the network installed in the elevator is also out of power, it cannot be used for the elevator remote monitoring and management. So, we develop an integrated and unified emergency call system, which can transmit not only telephone call but also data signals using PSTN(Public Switched Telephone Network) in order to remote monitoring and management of elevators, even though a power outage occurs. The proposed integrated emergency call system to process multiple data such as voice and operational information is a multi-channel board system which is composed of an emergency phone signal processing module and an operational information processing module in the control box of elevator. In addition, the RMS(remote management server) systems based on the Web consist of a dial-up server and a remote monitoring server where manages the elevator's operating information, status records, and operational faults received via the proposed integrated and unified emergency call system in real time. So even if there's a catastrophic emergency, the proposed RMS systems shall ensure and maintain the safety of passengers inside the elevator. Also, remote control of the elevator by this system should be more efficient and secure. In near future, all elevator emergency call system need to support multifunctional capabilities to transmit operational data as well as phone calls for the safety of passengers. In addition, for safer elevators, it is necessary to improve them more efficiently by combining them with high-tech technologies such as the Internet of Things and artificial intelligence.

Many components are used to control and manage factory automation. Networks and remote monitoring processes can be used for efficient management from distant locations. In this research, we develop a remote information management system using network for manufacturing systems. The target system is an integrated circuit (IC) test handler for semiconductor processes. The system consists of two classes: an actuator process for control sensors, motors and cylinders and a monitoring process (i.e., GUI: graphical user interface) for displaying operational status on the screen. The component logic makes up the remote status view of the GUI communication modules, which has an associated message interrupt method and timer. This research targeted the IC test handler system, which can be displayed over the web for review and analysis. The proposed method improves the analysability by capturing the operational data between the monitoring process and the actuator process and through its supported function that allows operators or users

In this paper, we propose an automatic detection scheme of work distraction for remote management of telecommuting. The proposed scheme periodically captures two consequent computer screens and generates the difference image of these two captured images. The scheme applies the difference image to our deep learning model and makes a decision of abnormal patterns in the difference image. Our deep learning model is designed with the transfer learning technique of VGG16 deep learning. When the scheme detects an abnormal pattern in the difference image, it hides all texts in the difference images to protect disclosure of privacy-related information. Evaluation shows that the proposed scheme provides about 96% detection accuracy.

Since most education organizations such as Universities have a plenty of PCs, much electric power can be wasted if their power states are not managed properly. This paper introduces the RPM(Remote Power Management) software system implemented to reduce a waste of PC power in Universities. The System manager can monitor power state of all PCs in a University and turn off PCs or change power states of PCs to low power states. The RPM consists of three software modules. First, Power Controller, which is installed in each user PC, saves the power by changing low power state by utilizing low power algorithm proposed in this paper. Also it reports power state of its PC to Power Server on the state changed. Second, Power Server module gathers power state information of all PCs, stores them in a DB, and sends all or some parts of the information to Power Viewer whenever the manager asks. The manager can turn off or change a certain PC to low power state. We evaluated the performance of power saving for the RPM and the result showed achievement of 40% power saving.
