As the need for the use of big data increases, various analysis activities using big data, including SNS data, are being carried out in individuals, companies, and countries. However, existing research on predicting technology market trends has been mainly conducted using expert-dependent or patent or literature research-based data, and objective technology prediction using big data is needed. Therefore, this study aims to present a model for predicting future technologies through decision tree analysis, visualization analysis, and percentage analysis with data from social network services (SNS). As a result of the study, percentage analysis was better able to predict positive techniques compared to other analysis results, and visualization analysis was better able to predict negative techniques compared to other analysis results. The decision tree analysis was also able to make meaningful predictions.

Continued jobless growth in economy, coupled with the current economic recession, is aggravating the situation of job market. In order to create more jobs and reduce the economic gap in a society, an independent creative firm of a sole entrepreneurs is suggested as an alternative mean. Understanding entrepreneurial motivations of a sole entrepreneur will be helpful in developing educational programs on starting an independent creative firm and in establishing a relevant government policy. This study, therefore, proposes a new model on entrepreneurial motivations in the independent creative firm and performs case study. The results of the study show that the personal environment and the personal characteristics of entrepreneurs have much effects on motivation of starting the independent creative firms. Among the personal environments, entrepreneurs' educational backgrounds, work experiences, and personal networks have great influences on entrepreneurial motivations. The processes of sustained entrepreneurship involve: (a) the determination of business ideas and goals, (b) the inception of a new business and managerial activities, (c) the entrepreneur's assessment of both intrinsic and extrinsic rewards of business performances, and (d) the adjustment of business ideas and goals in accordance with the results of the assessment. The results of the study could be applied in developing educational programs and consulting guidelines on independent creative firms and in establishing government's supportive policies on the firm.

As a sub-concept of corporate or organization governance, business governance and IT governance have become major research topics in academia. However, despite the importance of process as a construct for mediating the domain between business and information technology, research on process governance is relatively inadequate. Process Governance focuses on activities that link business strategy with IT system implementation and explains the creation of corporate core values. The researcher studied the basic conceptual governance models of political science, sociology, public administration, and classified governance styles into six categories. The researcher focused on the series of metamodels. For examples, the traditional Strategy Alignment Model(SAM) by Henderson and Venkatraman which is replaced by the neo-SAM model, organizational governance network model, sequential organization governance model, organization governance meta model, process governance CUBE model, COSO and process governance CUBE comparison model, and finally Process Governance Framework and etc. The Major difference between SAM and neo-SAM model is Process Governance domain inserted between Business Governance and IT Governance. Among several metamodels, Process Governance framework, the core conceptual model consists of four activity dimensions: strategic aligning, human empowering, competency enhancing, and autonomous organizing. The researcher designed five variables for each activity dimensions, totally twenty variables. Besides four activity dimensions, there are six driving forces for Process Governance cycle: De-normalizing power, micro-power, vitalizing power, self-organizing power, normalizing power and sense-making. With four activity dimensions and six driving powers, an organization can maintain the flexibility of process governance cycle to cope with internal and external environmental changes. This study aims to propose the Process Governance competency model and Process Governance variables. The situation of the industry is changing from the function-oriented organization management to the process-oriented perspective. Process Governance framework proposed by the researcher will be the contextual reference models for the further diffusion of the research on Process Governance domain and the operational definition for the development of Process Governance measurement tools in detail.

The purpose of our research is to figure out the 'non-financial value' of consumers applying networks amongst consumer groups, the data-based marketing strategy to the analysis and delve into the ways for enhancing effectives in marketing activities by adapting the value to the marketing. To verify the authenticity of the points, we did the empirical test on the consumer group using 'the Essence Cosmetics Products' of high involvement that is deeply affected by consumer perceptions and the word-of-mouth activities. 1) The empirical analysis reveals the following features. First, the segmented market for 'Essence Consumer' is composed of several independent networks, each network shows to have the consumers that is high degree centrality and closeness centrality. Second, the result proves the authenticity of the non-financial value for boosting corporate profits by the high degree centrality and closeness centrality consumer's word-of-mouth activities. Lastly, we verify that there lies a difference in the network structure of 'Essence Cosmetics Market'per each product origin(domestic, foreign) and demographic characteristics. It does, therefore, indicate the need to consider the features applying mutually complementary for the network targeting.

최근의 정보보호 환경에서는 자신의 관리 도메인 내로 침입하게 되는 공격을 어떻게 잘 탐지 할 것인가와 탐지된 공격을 어떻게 효율적으로 차단하여 자신의 도메인을 잘 보호할 것인가에 초점이 맞추어 있다. 따라서 탐지된 침입의 공격자에 대한 대응도 자신의 도메인 경계에서 해당 트래픽을 차단하는 수동적인 방법 이외에는 별다른 방법이 없는 상태이고, 이 경우 자신의 도메인에서 파악한 침입자정보를 바탕으로 자신의 도메인 입구에서만 해당 트래픽을 차단함으로써 침입자는 자유로이 인터넷을 이용할 수 있을 뿐만 아니라 다른 공격 기술이나 공격 루트를 이용한 제2, 제3의 공격이 이루어 질수 있다. 반면 인터넷을 이용한 경제 활동 및 그 액수가 점차 증가함에 따라 사이버 공격으로 입게 되는 피해는 점차 기업의 생존을 위협하는 수준에 도달하고 있다. 따라서 해킹에 능동적으로 대응할 수 있는 기술이 요구된다고 할 수 있으며, 능동적인 해킹 방어를 위한 가장 기본적인 기술로 해커의 실제 위치를 추적하는 역추적 기술을 활용할 수 있어야 한다. 그러나 현재까지 제안된 역추적 기술들은 인터넷이 보유한 다양성을 극복하지 못하여 현재의 인터넷 환경에 적용하는데 어려움이 따른다. 이에 본 논문에서는 해킹으로 판단되는 침입에 대하여 라우터의 구조적 변경 없이 효율적으로 역추적 하기 위해서 ICMP 역추적 메시지(ICMP Traceback Message)를 이용한 ICMP 기반의 역추적 시스템을 설계한다.
