This study explores the possibility of innovative government's administrative services to the public by reflecting the social implications of 'Big Data'. In particular, the idea of OPP (Order Penetration Point) and SOP (Service Offering Point) as a management scheme for the extension of administrative processes into the resident's living space is proposed to overcome the inherent limits of e-government service quality, the root cause of which is believed in the segregation of two spaces - the resident's living space and the government's offices. Furthermore, a discussion is made on how to integrate sensor data from the resident's living space with traditional administrative database, which is a new challenge in the course of synchronizing the two spaces. The implications on the process extension are also provided centering around the shift from reactive to proactive services.

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.

Lee, Seung-Jae ;
Journal of Digital Convergence, volume 13, issue 5, 2015, Pages 177~185
DOI : 10.14400/JDC.2015.13.5.177
The gender difference in social roles affects digital devices' utilization differences in man and woman even in the 21st Century. Prior studies analyze the digital divide (genders, ages, etc.) from the assessment perspectives of digital equipment, such as PCs. In the area of high speed internet, most functions of PCs have been replaced with smartphones, and around 80% of the mobile phone users adopt smartphones. Subsequently the inequality of physical access to the digital devices is no longer a criterion for digital divide. The focus on digital divide should be shifted from the physical access to other factors, such as socio-technical or socio-cultural ones. This paper examines utilization of women's digital equipment, in particular, preparing for tourism activities, which is popular but sensitive to the technology. A survey was conducted with participants of [Suncheon Garden Expo] 2013. The results of this study capture the inactive use of digital devices particularly women over 50s. This phenomenon (high utilization of the digital devices for social or informative purposes, but low utilization of the digital payment) implies other aspects of Korean women (economic independence, low self-assertion, technical difficulties, etc.), which is considered from the socio-technological convergence perspective. This study also has a practical implication on the side of the digital device developers as well as marketing, where the qualitative communication is likely to be incorporated for the women over 50s.

In parallel with evolving information communication technology, M2M(Machine-to-Machine) industry has implemented multi-functional and high-performance systems, and made great strides with IoT(Internet of Things) and IoE(Internet of Everything). Authentication, confidentiality, anonymity, non-repudiation, data reliability, connectionless and traceability are prerequisites for communication security. Yet, the wireless transmission section in M2M communication is exposed to intruders' attacks. Any security issues attributable to M2M wireless communication protocols may lead to serious concerns including system faults, information leakage and privacy challenges. Therefore, mutual authentication and security are key components of protocol design. Recently, secure communication protocols have been regarded as highly important and explored as such. The present paper draws on hash function, random numbers, secret keys and session keys to design a secure communication protocol. Also, this paper tests the proposed protocol with a formal verification tool, Casper/FDR, to demonstrate its security against a range of intruders' attacks. In brief, the proposed protocol meets the security requirements, addressing the challenges without any problems.

This study aims to identify determinants affecting on geographic variations in the prevalence of arthritis in Korean women using data mining. Data from Korean Community Health Survey 2012 with 249 small districts were analyzed. Socio-demographic, health behavior and status, and morbidity status measures were analyzed using conventional regression model and convergence analysis method such as decision tree for convergence analysis. Rate of workers in agriculture, forestry, and fishing, salaried workers, persons higher than high school graduates, non-treatment of needing care, non-treatment of care because of economic reason, obesity, heavy drunkers, complaining persons of chewing difficulty, persons with experiencing depression, persons with perceiving stress, and persons with diagnosing hypertension and angina pectoris were variation determinants of prevalence of arthritis in 249 small districts and these districts were classified 10 area groups by decision tree model. Our finding suggest that the approach based characteristics by small area groups rather than national wide or individual level would be effective to reduce in variations of prevalence of arthritis.

The styles by character type in customizing systems were analyzed, being classified into creative style, attractive style, grotesque style, usual style, and suit style on the basis of the 'fashion style types of game characters' proposed in the previous research. The creative and convergent designs that couldn't be implemented in reality were expressed in various forms because those designs were created in virtual space, one feature of games. The analysis of the fashion styles of characters was focused on the RPG using the characters with exaggerated body proportions beyond the general body proportions in reality and the features on game characters that were identified by gamers. Thus, the creative style and attractive style showed a high frequency. The common features were identified because the costume designs and colors for characters are generally selected in accordance with the gamers' requests or by reflecting the view on the world. However, it was difficult to find out the representative cases for hair designs and colors because of excessively diverse expressions. The results of this paper will be a valuable reference for the research on the fashion item development manual satisfying the gamers' personalities and requests and relevant research.
