The rapid changes in business environments are also applicable to the delivery service field. Numerous companies are using smart phones in order to perform work of the delivery service field that is rapidly developing every year. Smart phones established ubiquitous work environments where access to the server of the head office is possible through telephones, scanners, and the internet anywhere and anytime. However, although smart appliances including smart phones have been diffused, empirical analysis of use of them in actual has not been attempted much. In this regard, current study empirically analyzes how connectivity and context-awareness function of smart phones based on the TAM(Technology Acceptance Model) influence the continuous intention to use through trust, usefulness, and ease of use. The results indicate that the connectivity and context-awareness function, which are natures of smart phones, had impacts on the ease of use and trust, but not on the usefulness. Based on these results, this study suggests implications and future research directions regarding the planning and realization of smart appliances.

This paper seeks to investigate the effect of technology readiness on the usage of smart entry service. The questionnaires were distributed to passengers who were experience with smart entry service and structural equation modeling was utilized to analyze the data. The results revealed that optimism had a positive impact on perceived usefulness and insecurity had a negative effect on perceived enjoyment. Perceived ease of use had a positive impact on perceived enjoyment, perceived usefulness and intention to use. In addition, perceived usefulness had a positive impact on intention to use. The results from this paper can be used as basic knowledge for developing the smart entry service activation plan.

A bathroom in house has been stressed not only as a space for physiology and hygiene but also leisure and healthcare. However, the bathroom is the most likely space where an elderly person can have an accident and it is uncomfortable space for them because of their deteriorating physical ability. So the purpose of this study is to help the elderly use their bathroom conveniently by providing smart service. Therefore, we carry out 18 smart service patterns that contain assistive devices and sensors for bathroom. Considering applicability and frequency, from among these service patterns, we suggest 4 service patterns. First is a fall prevention service. This service helps elderly use the bathroom safely at night. Second is a getting ready to go out service. This service helps the situation that elderly use the bathroom after getting up in the morning. Third is a security service in daily life especially before or after meals. And final is a service regarding personal hygiene service after returning home. This service helps to shower or bathe after return home. These services have positive influence in medical expense reductions, good health care and self-reliance of elderly.

As smart phones have become widely adopted, they have brought about changes in individual lifestyles, as well as significant changes in the industry. As the mobile technology of smart phones has become associated with all areas of industry, it is not only accelerating innovation in other industries such as shopping, healthcare service, education, and finance, but is also creating new markets and business opportunities. The preparation of thorough security measures for smart phones is increasing in demand. While offering excellent mobility and convenience, smart phones can be exposed to a range of violation threats. In particular, it is necessary to make efforts to develop a security system that can preemptively cope with potential security threats in the banking service area, which requires a high level of reliability. This paper suggests a security reference model that is considered for the smart phone-based joint mobile banking development project being undertaken by the Bank of Korea in 2010. The purpose of this study is to make a security reference model for a reliable smart phone-based mobile financial service, by recognizing the specific security threats directed toward smart phones, and providing countermeasures to these security threats. The proposed mobile banking security reference model is useful in improving system security by systematically analyzing information security threats to the mobile financial service, and by presenting the guideline for the preparation of countermeasures.

Smart-Phones are utilized in disaster management field because it can deliver disaster information to large population simultaneously and quickly, and provide accurate information through situation-based service using the LBS(Location Based Service). To study on the utilization of smart phone for disaster information collection and dissemination method, this study suggest a framework which connects smart phone by loading application for reporting disaster. The disaster monitoring and situation dissemination system framework using smart phone is composed of 4 parts. First, smart phone application enters image, video, voice and text information and location of the disaster. Second, the disaster report reception and situation dissemination server receives the information, save in the DB, and send through smart phone SMS. Third, store into disaster information database. Fourth, display the disaster report and management information on 2D GIS, support the decision making process in deciding whether to manage as disaster, and disaster management web service which disseminates situation.

This study is a smart tourism research based on face recognition applied system that manages individual information of foreign tourists to smartphone. It is a way to authenticate by using face recognition, which is biometric information, as a technology applied to identification inquiry, immigration control, etc. and it is designed so that tourism companies can provide customized service to customers by applying algorism to smartphone. The smart tourism system based on face recognition is a system that prepares the reception service by sending the information to smartphone of tourist service company guide in real time after taking faces of foreign tourists who enter Korea for the first time with glasses attached to the camera. The smart tourism based on face recognition is personal information recognition technology, speech recognition technology, sensing technology, artificial intelligence personal information recognition technology, etc. Especially, artificial intelligence personal information recognition technology is a system that enables the tourism service company to implement the self-promotion function to commemorate the visit of foreign tourists and that enables tourists to participate in events and experience them directly. Since the application of smart tourism based on face recognition can utilize unique facial data and image features, it can be beneficially utilized for service companies that require accurate user authentication and service companies that prioritize security. However, in terms of sharing information by government organizations and private companies, preemptive measures such as the introduction of security systems should be taken.

The purpose of this study is to identify pre-service elementary school teachers' difficulties and needs in the science class utilizing smart technologies. The participants were nine pre-service elementary teachers who had practical training at an elementary school and took classes related to technology, pedagogy, and science knowledge. The data was collected through semi-constructed and in-depth interviews. The documents such as participants' guidance plans, daily records produced in teaching practice was collected and analyzed. The results of the research are as follow: Pre-service teachers have usually used the technology as a secondary transfer media to convey the knowledge. We found that the pre-service elementary teachers had 15 difficulties in the science class utilizing smart technologies. In addition, they needed a class to focus more on teaching them by integrating technology knowledge, pedagogy knowledge, and science knowledge, and by sharing a real case of science class utilizing smart technologies.
