The purposes of this study are to provide background information to develop a family-friendly work policy and to increase the effectiveness and feasibility of this policy. We surveyed the performance of family-friendly work policies, and workers‘ needs and utilizations of 17 family-friendly work policies. We also examined the factors that influence the utilization of family-friendly work policies. The study sample consists of 197 working mothers who have at least one child under age 10. The major findings are as follows: 1) The most-needed family-friendly work policy among working mothers is child care leave 2) Of those family-friendly work policies that are not currently provided, the most-needed policy is family care leave 3) The size of firms, the provision of substitutes, and 40-hour work schedules are statistically significant variables that influence the provision of necessary family-friendly work policies and 4) In addition, the work place culture is a very important factor related to the utilization of work- and family-friendly policies.

The direction component uses mainly the sobel and FFT method. The sobel method is difficult to set representative direction when we wish to extract representative direction when we wish to extract representative direction component and the complicated processing process of sobel mask because same value appears in the low provision image or high provision image and we cannot accumulate tilt size in case of making accumulate after making unit vector to pixel. The method that uses FFT conversion for direction extraction is possible in case that ridge has correct direction specification and must use a special direction filter. After thinning the binary image to supplement above weak point in the paper, we extract direction component by pixel unit, and we extract the most direction components of pixel that exist in block of 8${\times}$8 pixels size as representative direction of ridge.

Smart City is gaining attention with the advancement of Information and Communication Technology (ICT). ICT provides the basis for smart city foundation; enables us to interconnect all the actors of a smart city by supporting the provision of seamless ubiquitous services and Internet of Things. On the other hand, Crowdsourcing has the ability to enable citizens to participate in social and economic development of the city and share their contribution and knowledge while increasing their socio-economic welfare. This paper proposed a hybrid model which is a compound of human computation, machine computation and citizen crowds. This proposed hybrid model uses knowledge-based crowdsourcing that captures collaborative and collective intelligence from the citizen crowds to form democratic knowledge space, which provision solutions in areas of civic innovations. This paper also proposed knowledge-based crowdsourcing framework which manages knowledge activities in the form of human computation tasks and eliminates the complexity of human computation task creation, execution, refinement, quality control and manage knowledge space. The knowledge activities in the form of human computation tasks provide support to existing crowdsourcing system to align their task execution order optimally.

The growth of computer resource and network speed has increased requests for the use of remotely located computer systems by connecting through computer networks. This phenomenon has hoisted research activities for application service provision that uses server-based remote computing paradigm. The server-based remote computing paradigm has been developed as the ASP (Application Service Provision) model, which provides remote users through application sharing protocol to application programs. Security requirement such as confidentiality, availability, integrity should be satisfied to provide ASP service using centralized computing system. Existing Telnet or FTP service for a remote computing systems have satisfied security requirement by a simple access control to files and/or data. But windows-based centralized computing system is vulnerable to confidentiality, availability, integrity where many users use the same application program installed in the same computer. In other words, the computing system needs detailed security level for each user different from others, such that only authorized user or group of users can run some specific functional commands for the program. In this paper, we propose windows based centralized computing system that sets security policies for each user for the use of instructions of the application programs, and performs access control to the instructions based on the security policies. The system monitors all user messages which are executed through graphical user interface by the users connecting to the system. Ail Instructions, i.e. messages, for the application program are now passed to authorization process that decides if an Instruction is delivered to the application program based on the pre-defined security polices. This system can be used as security clearance for each user for the shared computing resource as well as shared application programs.

In this paper, we propose the fast wakeup and connection mechanisms for various energy saving schemes in order to improve QoS. First, we offer the interconnection of heterogeneous access networks via the Media Independent Information Server/Service (MIIS). Then, we propose the fast wakeup and connection mechanism for multi-interface communication systems. The proposed novel mechanism focuses on the fast provision of incoming service destined to the interface currently in energy saving mode by using MIIS-assisted interconnection. We further evaluate the performance of proposed mechanism through the numerical and experimental analysis.

What is an ideal authentication method for smartphone banking services? And what are the critical elements to be considered when designing it? To provide valuable insight for these questions, this study investigates various authentication requirements to be considered in smartphone banking service with the aspect of security, convenience and cost. By applying Analytic Network Process (ANP), this study first analyzes priorities among the requirements and then draws an ideal authentication method for smartphone banking service. Moreover, a sensitivity analysis has been conducted by varying the relative importance of several requirements. The results from the judgment of 72 experts revealed that, although Korean government has obliged the use of Public Key certificate, OPT and biometric alternatives may prove to be more appropriate for the smartphone banking service. These results will contribute to the provision of more secured and convenient smartphone banking services.
