항만물류는 그 특성상 global visibility와 traceability가 요구된다. 그러나 현재까지 항만물류에 적용된 전통적 인 RFID기술로는 이러한 요구에 부응할 수 없다. 최근의 IP-USN 또는 M2M과 같은 기술들은 네트워크가 구성되어 있어야 한다는 전제와 대량의 컨테이너가 장치되어 있는 항만물류 거점에서는 폭발적인 통신량으로 인한 문제가 발 생한다. 또한 최근의 항만물류 관련 이해관계자들의 요구는 보다 적극적인 대응을 할 수 있는 기술과 방법을 요구하 고 있다. 이러한 요구와 문제를 해결하기 위해 본 논문에서는 IP-RFID 기반의 스마트 항만물류서비스시스템을 제안 한다. IP-RFID 기반의 스마트 항만물류서비스시스템은 스마트 RFID 태그와 센서, 그리고 인터넷에 연결해 주는AP를 태그와 분리하여 통신 문제를 해결하였다. 온도센서, 습도센서, 충격센서, GPS 등이 연결된 태그는 컨테이너에 부착 되어 언제 어디서든 원하는 정보를 실시간으로 획득할 수 있어 글로벌한 추적과 투명성을 보장받을 수 있다.

The nature of port logistics requires global visibility and traceability. However, the traditional RFID technology still applied cannot meet these demands. IP-USN and M2M in port logistics have faced challenges of the prerequisite of network composition and immense communications at the base where a grand number of containers are installed. To resolve the issue, this study suggests an IP-RFID-based smart port logistics service platform. The IP-RFID-based port logistics service system resolved the communication problem by separating the RFID tag and AP, which allows internet connection, from the tag. The tags connected with thermo-sensors, humidity sensors, pressure sensors, GPS, etc. are attached to the containers insuring global visibility and traceability, key factors in logistics, by obtaining desired real-time information regardless of time and location.

전통적으로 제품이나 서비스의 가치는 생산자에 의해 고객에게 제공되었다. 그러나 현대에 와서는 제품이나 서비스의 개발에 고객들의 참여가 폭 넓게 이루어지고 있다. 공동가치창출과 같은 공동혁신을 통해 고객은 기업의 제품이나 서비스의 설계, 생산, 마케팅, 그리고 판매 등에 참여하여 새로운 가치를 창출하고 있다. 공동가치창출과 같은 공동혁신을 통해 생산자와 고객 간의 벽이 무너지고 있는 것이다. 정보기술의 발전으로 인해 고객의 경험을 공 유할 수 있는 기회가 증가하고 있다. 공동혁신은 새로운 경영기법을 적용하는 것이 아니라, 기업 활동과 세부 업무 자체를 변화시키는 패러다임으로 기업 활동에 고객이 참여하여 새로운 가치를 창출하는 것은 기존 업무 프로세스로 는 수행하기 어렵고, 업무 프로세스를 공동혁신 활동에 맞추어 새롭게 변화시켜야 한다. 본 연구에서는 공동혁신을 통해 새로운 비즈니스 모델을 개발하기 위한 프레임워크와 이를 위한 서비스 플랫폼의 개념적 모델을 제시한다.

Traditionally, the value of a product or service was provided to customers by the manufacturer. However, in modern society, participation of consumers in the production of goods and services is widely integrated into the general activities of corporations. Collaborative innovation refers to the company and customer working together in creating value with the customers participating in the designing, production, marketing, and sales of products. Accordingly, it would be ill-fitted to conduct collaborative innovation using previous business methods. Though collaborative innovation in the business sector is expected to increase, there are limits to its implementation at present. This study proposes framework in developing collaborative innovation-purpose business models and a conceptual platform for its execution.

As the elderly population is becoming an aging society, the elderly are experiencing many problems. Social security costs for the elderly are increasing and the un-linked social phenomenon is emerging. Thus, the social infrastructure and welfare system established in the past economic growth period are in danger of not functioning properly. People socially isolated or with chronic diseases among the elderly are exposed to various accidents. Thus, an active healthcare management service is imperative. Additionally, in the event of a dangerous situation, the system must have ways to notify guardians (family or medical personnel) regarding appropriate action. Thus, in this paper, we propose the smartphone-based healthcare and emergency response service platform. The proposed service platform aggregates movement of relevant data in real-time using a smartphone. Based on aggregated data, it will always recognize the user's movements and current state using the human motion recognition mechanism. Thus, the proposed service platform provides real-time status monitoring, activity reports, a health calendar, location-based hospital information, emergency situation detection, and cloud messaging server-based efficient notification to several subscribers such as family, guardians, and medical personnel. Through this service, users or guardians can augment the level of care for the elderly through the reports. Also, if an emergency situation is detected, the system immediately informs guardians so as to minimize the risk through immediate response.

In order for end-users in home networks to receive opportunities for useful services that go beyond legacy Internet Protocol TV (IPTV) services, this paper proposes a service platform that resides on the residential gateway (RG) for interworking between the home network and IPTV. This proposed service platform is called the home-oriented IPTV service platform (HISP) on the RG (HISP-RG). The proposed HISP-RG provides open architecture and functionalities to enable 3rd party IPTV service providers to locally and directly deliver home-oriented IPTV services to end-users in home networks. The HISP-RG can be an "add-on" and not a "built-in" solution for the existing standard RG. This paper introduces several home-oriented IPTV services that can be executed and delivered locally through the HISP-RG. Then, the open architecture and functionalities of the HISP-RG are defined and their requirements are specified. Finally, use cases of the HISP-RG for home-oriented IPTV services are presented.

In this study, it was intended to explore a way to build a DB which links the resources and areas and regions already registered as cultural assets in connection with a project which is newly building local culture and arts resources. Towards this end, this study first identified the type and scale of existing local culture and arts resources that could be linked. Following which, to link the local cultural resources and collected cultural assets, this study investigated the websites such as the Cultural Heritage Administration's National Cultural Heritage Portal, municipal and provincial tangible cultural festivals, municipal and provincial intangible cultural assets, and Gyeonggi Memory. Furthermore, this study identified the amount of information sources to be built and the current status of each information source to identify detailed information sources. Finally, the metadata of local culture and arts resources were presented by classifying them into material and publication data metadata, document metadata, audiovisual metadata, oral recording metadata, village information metadata, and personal information village information metadata.

There are a great number of Internet-connected devices and their information can be acquired through an Internet-wide scanning tool. By associating device information with publicly known security vulnerabilities, security experts are able to determine whether a particular device is vulnerable. Currently, the identification of the device information and its related vulnerabilities is manually carried out. It is necessary to automate the process to identify a huge number of Internet-connected devices in order to analyze more than one hundred thousand security vulnerabilities. In this paper, we propose a method of automatically generating device information in the Common Platform Enumeration (CPE) format from banner text to discover potentially weak devices having the Common Vulnerabilities Exposures (CVE) vulnerability. We demonstrated that our proposed method can distinguish as much adequate CPE information as possible in the service banner.

This study investigates the practices of Western YouTube content creators' cross-posting behavior, i.e., uploading their content on Bilibili-a Chinese video-sharing platform. A qualitative content analysis is employed to analyze videos of 14 popular YouTubers to compare the content of videos posted on both platforms. The findings indicate that the content differs for both platforms, possibly to accommodate Chinese viewers. The results show that Western YouTubers have made multiple changes to their original content before reuploading them to Bilibili, including the addition of Chinese subtitles, cut-out sponsorship content, shorter and translated descriptions, altered thumbnails, and exclusive content for Bilibili. The results also show a less frequent uploading schedule on Bilibili than on YouTube. While existing studies have explored content creators' cross-posting behavior within the same social media ecosystem, the study significantly contributes to advancing our understanding of online creators' content distribution practices across platforms in different cultural domains, especially in a Chinese-Western context.
