스마트폰의 확산과 함께 소비자들의 소비 환경과 행태가 변화하면서 기업은 온라인과 오프라인을 연계하는 O2O 서비스를 제공하고 있다. 기존의 O2O 서비스는 제품 정보를 기반으로 온라인 쇼핑을 제공하고 있으나 온 오프라인 매장 간의 연동에 한계가 있다. 이에 본 논문에서는 온라인 쇼핑몰, 오프라인 매장을 통합하여 상품에 대한 정보 제공과 제품 판매 서비스를 제공하기 위해 스마트 피팅 시스템을 활용한 O2O 연계시스템을 제안한다.

Recently, as smart phone technology is developing, wearable devices is also accelerating. But, the wearable device is necessary to operated for a long time with a small electric power because werable device is made compact. In this paper, we design and implement efficient lithium polymer battery model suitable to miniaturized wearable device in oder to maximize ease of use. The proposed model is characterized by a compact size of the battery by applying a thermal element and a light-weight battery. Also, proposed model gives greatly improve the life of wearable devices because it uses a method using the characteristics of the Peltier device using the temperature difference between the room temperature and body temperature of a person to generate power for charging. In particular, the proposed model can be used for the wearable device, as well as auxiliary charging of the smart phone.

Recently, the development and dissemination of smart devices linked to the network are being actively performed, and IOT(Internet of things) is issued form of mutually cooperative relationship through interoperation within smart devices. In this paper, we propose an innovative intelligent coffee shop management system by sharing and cooperatively controlling smart devices and Internet devices. The system can order smartphones including kiosk orders and beacon-based user identification. And it is a system that can make custom order without grasping user location information using geofence. The paper provides weather, temperature, time and user-based recommendation services based on Big Data. Therefore, the system is increased cost reduction and work efficiency than general coffee shops.

Though digital imaging devices such as smart phones, digital cameras and office scanners have improved significantly over the past years, they are seldom used for industrial application. This may be attributable to high level of quality and performance requirement for industrial application, but there lacks a test or an objective evaluation whether the upgraded performance of entry-level device is sufficiently enough to replace existing industrial equipments or not. If there exists an industrial application area where the applicability of entry-level equipment is proved by some objective tests, then companies will be able to reduce investment on expensive industrial equipment. In this study, applicability of entry-level digital devices for color difference discrimination of PVC (Polyvinyl chloride) color sheet is tested. By testing smart phone, digital camera, and office scanner for color difference discrimination, authors have found that office scanner shows consistent result with less measurement error. Additional experiment on comparing office scanner with industrial spectrophotometer has confirmed that there exists high correlation between the two devices' results. Based on this result, office scanner may be applicable to discriminate the color difference of PVC sheet instead of expensive industrial spectrophotometer if proper management criteria are established.

In recent years, domestic electronics, banking, electricity, services, manufacturing, pharmaceutical, corporate type and malicious hackers is corporate security through the accident occurred and the resulting loss of corporate information and the damage each year is steadily increasing. Many companies have responded to domestic business activities and to protect critical information related to laptops, smart phones, tablets, and introduced a variety of Endpoint security solutions within. However, being introduced to senselessly Endpoint security solution across the over-budget, with the same features and performance, such as conflicts and problems arise, resulting in additional maintenance costs, in an effort to resolve the conflict in the operational security of the IT department's new difficulty in becoming. Here is the introduction and operation of these Endpoint security solutions in order to solve the problem on employees's PC into the center of the information security governance based on Endpoint security solution to provide the process for determining the solutions presented.

A meta-analysis is a statistical literature synthesis method that provides the opportunity to view the research context by combining and analyzing the quantitative results of many empirical studies. The technology acceptance model (TAM) has been the subjects of a great deal of MIS research in the last two decades and now also has been continuously studied. Recently, the convergence of knowledge information society and information telecommunication technologies has a rapid impact on politics, economics and various fields. The biggest issue in the information communication and information systems fields is smart. Therefore, we conducted a meta-analysis research on the behavioral intention of smart phone users based on technology acceptance model. Also, this study was targeted a total of 50 research papers that are setting up the causal relationship in TAM among the research papers published in domestic academic journals since 2005. The result of the meta analysis, showed that the effect size was 0.48 in the path from perceived usefulness to behavioral intention, it showed that the effect size was 0.46 in the path from perceived ease of use to behavioral intention. And, it showed that the effect size was 0.46 in the path from perceived ease of use to perceived usefulness. Also, it showed that the effect size was 0.61 in the path from attitude to behavioral intention. Based on the results, it was discussed the difference through comparative analysis with previous research.

In this paper, we propose a device identification system for network visibility that can maintain the secure internal network environment in the IoT era. Recently, the area of enterprise network is getting huge and more complicated. Not only desktops and smartphones but also business pads, barcode scanners, APs, Video Surveillance, digital doors, security devices, and lots of Internet of Things (IoT) devices are rapidly pouring into the business network, and there are highly risk of security threats. Therefore, in this paper, we propose the device identification system that includes the process and module-specific functions to identify the exploding device in the IoT era. The proposed system provides in-depth visibility of the devices and their own vulnerabilities to the IT manager in company. These information help to mitigate the risk of the potential cyber security threats in the internal network and offer the unified security management against the business risks.

Recently, WiBro service as a mobile internet has been being extended. The market of wireless data communication has been being extended rapidly due to the increase of mobile data communication service supply such as smart-phone, WiBro service and so on. As the result, security is also emphasized in the mobile Internet In this paper, we propose the methods that tighten up security in the upcoming Enterprise Mobile-VPN service on WiBro network.

Currently in many places, such as a business or government office, customers are spending many time after issuing waiting number ticket. To improve this, this paper proposes new design of waiting number ticket issuing system which provides real-time notification service with smartphone. This system add the NFC tag to the issuing machine in order to input the information of waiting and increase the convenience of users and provides an integrated management of corporate and government information using a waiting number ticket. Therefore, it is possible to efficiently use the waiting time than when using the existing ticketing system by taking advantage of this system, and appears to be to reduce costs and environmental protection, by not using the paper ticket. Also this system can be used to improve business processes through the application Waiting Number Ticket ticket cancellation feature.

Today, as wireless communications devices such as laptops, smart phones are generalized, wireless LAN has been widely installed in the corporate office conference rooms, industrial warehouses, Internet-ready classrooms, and even in a coffee shop. Though a wired network can be accessed and attacked only by the physical penetration, the wireless network which can be accessed anywhere within the reach of anyone has relative vulnerability by unauthorized users' attack. To defend these vulnerabilities, the introduction of WIDS / WIPS is required. In this paper, we recognize the limitations of WLAN security technology, review the current technology trends and propose the solutions in the future security problems.
