We investigate the underlying structure of big data research domain, which is diversified and complicated using bottom-up approach. For that purpose, we derive a set of articles by searching "big data" through the Korea Citation Index System provided by National Research Foundation of Korea. With some preprocessing on the author-provided keywords, we analyze bibliometric data such as author-provided keywords, publication year, author, and journal characteristics. From the analysis, we both identify major sub-domains of big data research area and discover the hidden issues which made big data complex. Major keywords identified include SOCIAL NETWORK ANALYSIS, HADOOP, MAPREDUCE, PERSONAL INFORMATION POLICY/PROTECTION/PRIVATE INFORMATION, CLOUD COMPUTING, VISUALIZATION, and DATA MINING. We finally suggest missing research themes to make big data a sustainable management innovation and convergence medium.

Traditionally we consider the food and the medicine have common roots, that is, energies from them share the same source, and it brought us an unique food culture of our own, and nurtured an unique academic area of oriental medicated dietary therapy. Thus we devise chocolate based on oriental theory and western food and convergence prevention nutritional approach. The study analyzed and examined the nutritional composition, physical properties and analysis DPPH radical scvenging, total polyphenolic compound contents, total flavonoids contents of chocolate added with 5% tangerine peel powder(TPC). Total polyphenolic compound content of TPC was 394.1 mg GAE/100g and DPPH radical scvenging activity was 68.66% and total flavonoid content was 148.88 mg QE/100g. Antioxidative activity of TPC was significantly higher than that of come into the market milk chocolate(p<0.05). In sensory evaluation, significantly difference(p<0.05)of TPC were surface color, flavor, overall acceptance.

The year 1997 was when Korean Journal of Public Relations Research started to publish research articles. This study addresses the issue of theories in Korean public relations research. A total of 166 research papers are analyzed to see characteristics and changes during 2003-2012. Through this meta analysis, the researcher tries to see the big picture and discusses the right direction for the future of the public relations in many ways. Three different groupings were adopted to classify theories in the 10 year perion - 1. origins of theories(public relations field, related neighbor field, distant field), 2. target of analysis(individual, organization, society), 3. level of approach (systematic pluralistic, rhetorical, critical approach). According to the findings, though getting better, it was 'cold season' in public relations research because theories utilized in Korean public relations research were not very excellent qualitatively and qualitatively. Interdisciplinary approach is discussed.

The organizations and companies establish personal information protection policy under the law and guidelines. They carry out access control without consideration for distinctiveness of the information although the damage degree varies when the information is leaked. Considering the distinctiveness, a policy needs to be made for individuals to protect his personal information. However, he is not able to write the policy because of lack of understanding the system. To write his own policy efficiently, the system that authorizes ones according to service list provided by organizations is necessary. This paper suggests the model and method that write personal policy for his information protection based on the service list provided by organizations. Through this model, fine-grained authorization and policy change are easily made and ultimately the access control customized according to one's own information is possible.

This study was done to examine the relation of cognitive function, depression and anxiety in elderly people above 65 years of age, and to identify factors influencing anxiety. The data were collected from June 1 to August 30 2014. Data were collected by questionnaire from 363 elderly people. The instruments for this study were MMSE-DS, depression, anxiety. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple linear regression with the SPSS/WIN 18.0 program. According to results, the significant factors influencing anxiety were sleeping time(${\beta}=-.249$, p<.001), depression(${\beta}=.218$, p<.001), cognitive function(${\beta}=-.209$, p<.001), occupation(${\beta}=-.133$, p=.006). The study reveals that it is necessary to develop a convergent program that maintain adequate sleep, prevents of cognitive impairment and decreases depression.

This study was intended to investigate the effect of life stress of university students on the suicidal ideation and to verify the mediating effect of personal mental health on a relationship between life stress and suicidal ideation. Therefore, this study collected data from 491 university students who are enrolled in 4 universities located in Daejeon Metropolitan City, Chungnam, and Chungbuk. According to the main findings of this research, life stress, suicidal ideation, and mental health had statistically significant correlation. Secondly, life stress not only makes direct effect on the suicidal ideation, but makes indirect effect through a mediating variable, the mental health, as well that mental health is verified to mediate a relationship between life stress and suicidal ideation. The research results suggest that mental health of university students is impoverished when life stress is higher, and can make effect on the suicidal ideation due to continual phenomenon of losing general function of life. This study investigated how counselors can intervene convergence policy approach with mental health of clients that affects the relationship between life stress and suicidal ideation of university students, and suggested implication and limitation of this study and suggestions for a follow-up study.
