Recently, the frequency of dealing important information regarding financial services like paying through smart device or internet banking on smart device has been increasing. Also, with the development of smart device execution environment towards open software environment, it became easier for users to download and use random application software, and its security aspect appears to be weakening. This study inspects features of hardware-based smart device security technology. Furthermore, this study proposes a realization method in MTM hardware-based secure smart device execution environment for an application software that runs in smart devices. While existing MTM provides the root of trust function only for the mobile device, the MTM-based mobile security environment technology proposed in this paper can provide numerous security functions that application program needs in mobile device. The further researches on IoT devices that are compatible with security hardware, gateway security technology and methods that secure reliability and security applicable to varied IoT devices by advancing security hardware are the next plan to proceed.

In the present study, we conducted in-depth interviews with school dieticians and nutrition teachers to determine the local foods they were aware of and their experiences with local foods. We also aimed to obtain more detailed measures for local food vitalization and suggestions for improvements. In-depth interviews were performed with 8 school dieticians and nutrition teachers, who stated that local food vitalization was needed for school food services, because it could be a foundation for securing safefood products, student healthi mprovements, environmental protection, and the establishment of a general consumption market. However, they were aware of a higher number of disadvantages than advantages in school situations and indicated the deterioration of the quality of food products as the biggest disadvantage. The most-suggested measurement items for local food vitalization in schools included improvement of the food distribution system, expansion of education, information sharing, prevention of monopolies, improvement of food-product quality, and mass production. In addition, it was suggested that school dieticians and nutrition teachers should invest efforts in the development of excellent recipes and varied diets utilizing local foods. Therefore, system supplementation is urgently required in order for school food service officials, and consumers, to efficiently introduce and vitalize local foods. It is also necessary to foster an environment that encourages trust-based relationships with producers to maximize the effect of system supplementation. This would be the foundation for improving the health of students, improving food-service quality, nutrition management, and vitalization of the regional economy in the future, and will positively affect students' food consumption patterns even after they become adults.

This paper is to analyse statutes and execution system on 'plain language policy' of the U.S. in the process of policy was instituted, and to suggest the meaningful implications for Korean easy public language improvement project based on the conclusions drawn. The summarized conclusion is as follows. First, the continuous interests of Presidents and taking the lead of federal agencies played important roles until the U.S. plain language policy has been established as a system. Second, in executing the U.S. plain language policy, laws legislated by period contributed to elicit mandatory compliances from the federal agencies. Third, a propelling agent of plain language policy, PLAIN, is not an administrative department but a community consisted of federal employees and experts. Fourth, plain language policy was unexpectedly given wholehearted support and assistance by Presidents and their administrations from the reform-minded Democratic party. Fifth, during the 2000s most federal departments and agencies held self-managed websites and programs related to plain language. To conclude the current U.S. plain language policy surely performs a mechanism to improve communication and a role as a ladder of trust between the public and government.

Purpose: The purpose of this study was to explore decision making experiences of Korean women with breast cancer who underwent breast reconstruction with/after a mastectomy. Methods: Data were collected during 2015-2016 through individual in-depth interviews with 10 women who had both mastectomy and breast reconstruction, and analyzed using phenomenological method to identify essential themes on experiences of making a decision to have breast reconstruction. Results: Five theme clusters emerged. First, "expected loss of sexuality and discovery of autonomy" illustrates various aims of breast reconstruction. Second, "holding tight to the reputation of doctors amid uncertainty" specifies the importance of a trust relationship with their physician despite a lack of information. Third, "family members to step back in position" describes support or opposition from family members in the decision making process. Fourth, "bewilderment due to the paradox of appearance-oriented views" illustrates paradoxical environment, resulting in confusion and anger. Lastly, "decision to be made quickly with limited time to oneself" describes the crazy whirling process of decision making. Conclusion: Findings highlight aims, worries, barriers, and facilitators that women with breast cancer experience when making a decision about breast reconstruction. Deciding on breast reconstruction was not only a burden for women in a state of shock with a diagnosis of breast cancer, but also an opportunity to decide to integrate their body, femininity, and self which might be wounded from a mastectomy. These findings will help oncology professionals provide effective educational counselling before the operation to promote higher satisfaction after the operation.

A node of mobile IPv6 moving foreign networks needs authentication process to support right services against from security threat. AAA is a trust infrastructure that authenticates, authorizes, and accounts nodes receiving a network service. And Mobile IPv6 Working Group recommends use of AAA infrastructure to authenticate mobile nodes. Event though AAA infrastructure provides strong authentication functions, it should exchange a lot of messages to authenticate mobile nodes every movement. The exchange of lots of messages causes latency and it is interfered with realization of real-time communication. This paper proposes an authentication method of improved speed using hash value of mobile node to reduce authentication latency. Directly after movement, a mobile node applying a Proposed method uses extended existing security authentication for a while and deletes the establishment latency of new security authentication. Performance evaluation of a proposed method verifies the efficiency through the analysis of cost comparison with other methods. The conclusion of performance evaluation is that the proposed method gets more 25% performance improvement than a general method when a mobile node moves another subnet.

Among the customer-oriented data used to comprehend the customer, the user review data has received much attention as it provides insights into customer opinion in a detailed and large-scale manner; many customers have come to rely upon and trust the user reviews. Many application developers are cognizant of the importance of user reviews, so they monitor and respond to these reviews. However, due to the absence of a systematic method, developers have been investing their time and money without clear correlation to the customer satisfaction. Therefore, this paper suggests a systematic method to select user reviews from the application market using the Kano Model that deals with customer satisfaction and service quality, thereby maximizing the customer satisfaction under the given time period and budget. This method is constructed in the following phases: the user review collection and requirement elicitation phase in which the developers collect user reviews from the application market and elicit requirements, the Kano Model application and selection phase in which the Kano Model is applied to the elicited requirements and selection occurs based on the quality type, and the stakeholder review and redefinition phase in which relevant personnel gather to review and redefine requirements from an internal perspective.

The problem of the objective adequacy on land estimation has been seriously discussed with the Issue of paradigm conversion on land policy as the economy situation has been worse enough to be confused due to the sale price which could not be predicted in Korea. Especially as the data of the government land value is not recognized as the official one, the separate alternation has been adopted to calculate the value of land compensation or development allotment. Rather it has raised a question in argument that the system of the declared value does not accomplish its basic function properly on the contrary of the original purpose to unify the computation of the government land value. To reconsider the adequacy of government land value, the most crucial factor is to select the items of land estimation reasonably. In addition, it is urgently required to develop the system of digital contents to provide the data of land evaluation which most of people could trust, who are facing of the flood of information through internet.
