DOI : 10.14400/JDC.2016.14.6.1
The definition of digital poverty of multicultural families has not been changed since it was used at the first digital divide survey in 2012. The objective of this study is to reexamine and redefine digital poverty targets of digital divide survey for multicultural families. The results suggest to reexamine multicultural families rather than limiting to Immigrant women for digital poverty. The results were as follows. First, the current survey has been limited to the migrant women for information gap survey of married migrants. But, It is expected to increase immigrant men in the future. It should include migrant men in the marginalized target in terms of preparation for a multicultural society. Second, the current survey has been limited to the migrant women for information gap survey. But, It is expected to increase children of multicultural families. This information gap is likely to be linked to differences in education or future economic disparities for children of multicultural families. It should include children of multicultural families in the marginalized target in digital divide survey.

Since continuous expand in governmental R&D investments and growth number of research institutions, model of multi-agency program has been planned and pushed ahead to settle the inefficiency of investment by the scattered and competitive R&D Programs. However, it was often pointed out that new model's effect has been fall because the institutional inertia of cooperative system between agencies. In this study, we analyze the current state of multi-agency program and suggest the optimal R&D governance model to improve a better direction. Afterward, several problems were turned up and that allocation and execution of the R&D budget separately, less coordination and cooperation among agencies, and absence of typical evaluation system of multi-agency program. Therefore, we suggest some of improvements by analyzing each steps.

Baby boomers who were born right after Korea War make up about 15% of population of Korea and lead an aging society rapidly. They're retiring since from 2012 and going to make up nearly 80% of total of old retirees. Baby Boomers with much higher income and education levels are going to enjoy their retirement as traveling. Therefore, this study invests the relationship between lifestyle and travel product selection of baby boomer consumer. Two big results are as follows. One is that baby boomers progress consumption activity(because they have their own purchasing power) and have health and leisure lifestyle and family lifestyle. The other is when they select travel product, they eventually consider three elements- travel company, transportation, and travel colleague.

A Study and Review of Gender Inequality Index
Seong, Moonju ;
Journal of Digital Convergence, volume 14, issue 6, 2016, Pages 43~49
DOI : 10.14400/JDC.2016.14.6.43
This paper explains concepts and methods of indexes measuring gender gaps. There are mainly 4 indexs, GDI, GEM, GII and GGI. UNDP developed GDI, GEM and GII. WEF developed GGI. Each index has its own strengths and weak points. Therefore it is important to understand each index in detail. For Korea, as men and women have been developed equally in areas of education and health, the GDI score was in a high group. However, the GEM and GGI scores were low. This implies that in order to reduce gender gaps, it is necessary to expand gender equality policies empowering economic and political empowerment.

DOI : 10.14400/JDC.2016.14.6.51
The modern state has always followed a variety of risks in the industrialization and informatization trends in the development of science and technology. Under such an environment, A matter of State compensation should take into consideration a variety of values such as harmony relief victims' rights in accordance with the principles of the rule of law, suppression of illegal acts of public servants, ensuring stable performance of official duties, the national treasury stability. As the state takes responsibility for an act of a public servant in a modern constitutional state, there may be a doubt on that the state takes responsibility only when there is a deliberation or a mistake. According to the theory of the self-responsibility, which suits the Constitution, the principle of liability with mistake on the State Compensation Law shall be excluded. I agree to the opinion that a subjective responsibility prerequisite such as a deliberation or a mistake is not required in relation to the liability of reparation on the State Compensation Law. Therefore, it is needed to convert the principle of state liability of reparation from the principle of liability with mistake to the principle of liability without mistake through a fundamental revision of the State Compensation Law.

DOI : 10.14400/JDC.2016.14.6.143
This paper's aim is to suggest the Expert System for analyzing relative combat power in ground operations. Since relative combat power analysis in terms of comparing combat power of friendly forces with one of the enemy can determine how the commander and staffs operate their unit afterwards, it requires fast and rational decision-making process. However, it has relied on manual method so far though Tactical Information Communications Network(TICN) into which numbers of applications can be loaded has been developed over a decade. 3 methods for analyzing relative combat power were expressed as mathematic rules to be used knowledge in the expert system after reviewing previous studies, and it studied how intangible power as well as tangible were reflected on total combat power. The expert system that will be built using EXSYS Corvid tool is expected to lessen error rate, provide faster decision-making, and reflect both intangible combat power and tangible one by using an appropriate weights in analyzing relative combat power. Next research filed includes how to build expert systems related with military personnel and intelligence areas for fast and rational decision-making processes.

Journal of Digital Convergence, volume 14, issue 6, 2016, Pages 177~186
DOI : 10.14400/JDC.2016.14.6.177
This study aims to explore the effect of characteristics of eWOM(Word-of-mouth) on consumer attitude in SNS(Social Network Service). The characteristics of WOM were classified into characteristics of message (polarity, verifiability, consensus) and characteristics of SNS (social presence, interaction). Data of 554 samples were collected from the university students of SNS users. The key results showed that the polarity of the WOM has a strong positive effect on consumer's attitude, and the degree of verifiability and consensus has a moderating effect on the polarity-attitude relationship. On the contrary, characteristics of SNS such as social presence and interaction have a direct effect on consumer attitude and have no significant moderating effect on the polarity-attitude relationship. This study provides an academic enhancement in the research of the relationship between the characteristics of WOM and consumer's attitude in the SNS environment. Practical implications are also drawn from these findings.

As many people use internet through the various programs of PC and mobile devices, the possibility of private data leak is increasing. A program should be used after checking security of information flow. Security analysis of information flow is a method that analyzes security of information flow in program. If the information flow is secure, there is no leakage of personal information. If the information flow not secure, there may be a leakage of personal information. This paper proposes a method of analyzing information flow that facilitates SAT solver. The method translates a program that includes variables where security level is set into propositional formula representing control and information flow. The satisfiability of the formula translated is determined by using SAT solver. The security of program is represented through the result. Counter-example is generated if the program is not secure.

The purpose of this study was to explore the influence of credibility of health information (CHI) source and e health literacy (eHL) on health information orientation (HIO) of parents of hospitalized children. Convenience sampling method of 109 parent whose children were admitted in a children's hospital in D city was used. The hierarchial regression model with general characteristics and characteristics of children for step 1 and eHL and CHI for step 2 against HIO was statistically significant (F=8.22, p<.001). And this model could explain 40% of HIO (
=.40). Especially, eHL (
=.54, p<.001) and CHI (
=.21, p=.008), subjective health perception (
=.19, p=.016), and age (

To solve various problems of the Internet as well as to enhance network performance, various future Internet architectures utilize cached data in network nodes or in proxy servers. Named-data networking (NDN), one of future Internet architectures, implements in-network data caching functionality, and then responds itself to request messages. However, it can cause users' privacy invasion that the publisher of data can not engage in the sharing/using process of the data anymore after the data was cached in-network. So NDN implements both encryption-based access control and group access control. But, since such access control schemes need to exchange additional messages in order to search for a proper access control list and keys, it causes inefficiency. This paper surveys the access control schemes of NDN, and then proposes an improved scheme.

The population over 65 years old is 12.7% of total population in 2014 and Korea is going to be an aged society in the near future. The transportation vulnerable including the aged should be guaranteed in walking mobility under safe and comfortable environment for their socio-economic activities. For the era of fusion and convergence this paper investigated the characteristics of walking accidents related to the aged pedestrians and analyzed the aged-oriented walking factors with a reaction time and a walking speed at crosswalks in Yeosu. In the results, the crashes for the aged occur at 9.9% of total crashes and the fatalities of the aged are 40.3% of total fatalities in 2014. The 47.4% of the aged fatalities is also attributed to vehicle-to-pedestrian accidents. The 49.3% of all pedestrian fatalities occurs at the aged pedestrians with a very high proportion. The reaction time and walking speed for the aged were determined as the values located at the lower 15%-tile of the elderly physical ability. It is shown that the reaction time is 4.56 seconds and the walking speed is 0.76 m/s in the case of Yeosu. From two factors' standpoint, the walking environment at crosswalks in Yeosu is inappropriate for the aged.

To achieve eco-friendly hospitals it is necessary to empirically verify the effect of meteorological factors on the power consumption of the hospital. Using daily meteorological big data from 2009 to 2013, we studied the weather conditions impact to power consumption and analyzed the patterns of power consumption of two hospitals. R analysis revealed that temperature among the meteorological factors had the greatest impact on the hospital power consumption, and was a significant factor regardless of hospital size. The pattern of hospital power consumption differed considerably depending on the hospital size. The larger hospital had a linear pattern of power consumption and the smaller hospital had a quadratic nonlinear pattern. A typical pattern of increasing power consumption during a hot summer and a cold winter was evident for both hospitals. The results of this study suggest that a hospital's functional specificity and meteorological factors should be considered to improve energy savings and eco-friendly building.
