While organizations are making a considerable effort to leverage formal and informal control mechanisms (e.g., policies, procedures, organizational culture) to improve security, their impact and effectiveness is under scrutiny as employees seldom comply with information security procedures. The best way to ensure the viability of a security policy is to make sure users understand it and accept necessary precautions. From an organization's perspective, a lack of security knowledge and awareness on the part of employees is a major problem. However, previous studies suggest that effect of security awareness education is inconsistent. Thus, this study is to find the answer why security awareness education is not effective. Conclusions and implications are discussed.

The number of welfare foundation to which local governments have contributed is 20 as of December, 2013. As the role of local governments tends to be more stressed than that of central government to achieve the fulfillment of local residents' welfare, the establishment of welfare foundation by local governments is increasing. Considering that the establishment of welfare foundation will increase in future due to the reinforcement of local autonomy it is evident to study the means to operate welfare foundations transparently and effectively. In this situation there has been neither review on the problems in the operation of welfare foundations until now nor study suggesting its improvement direction or activation plan. Therefore, this study delves into the current status of nation-wide welfare foundations and several problems occurred in the implementation process, and it is aimed to achieve the original goal of welfare foundations and the activation of welfare foundations.

The mobile instant messengers could change the lives of average citizens as much as did the telephone in the early part of the 20th century and television in the 1950s and 1960s. Researchers are debating whether the mobile instant messengers are improving or harming participation in community life and social relationships. For this study, 155 participants in two universities completed questionnaires pertaining to their own mobile instant messengers use and feelings of loneliness. We used survey data to examine the effects of the mobile instant messengers on social involvement and psychological well-being. In this sample, the mobile instant messengers were used extensively for communication. Results suggest that greater use of the mobile instant messengers were associated with declines in participants' communication with the people around which in turn creases their loneliness. These findings have implications for research and for the design of technology.

With regard to conventional theory, the rate of profit is determined by the interaction between the rate of surplus value and the organic composition of capital. And it declines with the capitalistic development through intensifying the organic composition of capital. According to the empirical test, the rate of profit and the rate of surplus value have been decreased. On the contrary, the organic composition of capital have increased during the period under study. The empirical results of the rate of profit in Korean economy appears to hold the principle of the law of the tendency of the rate of profit to fall. But the trend of the determinants is distinct from the conventional theory. Despite the distinctive empirical results, the law of the tendency of the rate of profit to fall is realized in Korean economy in objective period of time.

Currently, despite the quantitative growth of domestic journal, objective and metric criterion to evaluate the contents and quality of those journals is inadequate. As a result, depending on a foreign citation index like SCI to evaluate the research result is causing some problems such as, thesis of an excellent standard being presented and published in foreign countries, thus, neglecting journals written in Korean. Hereat, the Korea Citation Index(KCI) is constructing a database of the journals published by academic associations; scientific paper information, articles information, and bibliographic, analyzing the quoting relation. Consequently, KCI is providing the basic information and the corresponding quoting relations of journals and papers on its webpage. This study compares the impact level of domestic accounting related journals by KCI and analyzes the network among journals using the cross-citation frequency from a social network analysis point of view. As a result, Accounting-related journals are now more desirable than the location in order to have a variety of interdisciplinary research needs to be encouraged. Through this exchange of other disciplines and actively made, which is the phase of apparent accounting-related journals expect to be greatly enhanced looks.

One of the largest changes in retail business in Korea since the distribution market was opened in the mid 1990s is the appearance of foreign discount stores and the rapid growth of department stores. Discount stores and department stores have changed the structure of distribution business which has been primarily made up of traditional markets and supermarkets that have been the main retail markets in Korea. The retail business is changing from just a product purchasing place to a space where various values such as pleasure, happiness, etc. are provided. Therefore the purpose of this research is to grasp the effects that the shopping experience values at department stores have on the department brands, images, and awareness by means of theoretical and empirical research. Especially I classified the shopping experience values, an independent variable, into aesthetics, pleasures, consumers' interests, and services' excellence, and I verified whether they have a meaningful effects on the brand recognition and image, an endogenous variable, and the store royalty, a final various. A total of 235 questionnaires were used for analysis to test the research hypotheses. The positive analysis was done with SPSS 17.0K and AMOS 17.0 covariance structure analysis was performed. As a result, variables of the shopping experience values except consumers' interests seemed to have not only right influences on recognition and image, but also right influences on store royalty. Therefore this research shows that department store customers not only make use of department stores to buy products, but also visit department stores to get the values of pleasure and happiness, and that these aspects have a greater influence on the department store's image, recognition, or royalty in a sense.

DOI : 10.14400/JDC.2014.12.2.211
The study aims to estimate the determinants of policyholder's trust for the Chinese insurance industry by structural equation model. In particular, differences in determinants of trust among Chinese life insurance and auto insurance were derived from the latent mean and multi group analysis. The result shows the most effective determinants of trust were honesty, followed by credibility which shows the compensation ability of insurance company. However, benevolence is not influence statistically on the determinants of trust of both life insurance and auto insurance. Moreover, the policyholder's trust for the insurance industry was later extended to relationship commitment such as renewal and recommendation intentions. Especially, the linkage between the level of trust and relationship commitment was the strongest in life insurance than auto insurance. Even though the result is differ based on types of insurance, in order for the insurance industry to grow stably it is importance to get trust from policyholder.

The demand for messenger service goes on growing rapidly with widespread use of smartphones. Generally, the smartphone messenger provides group communication functions in which users can make the group and communicate with each other. In the mobile meeting, the attendees can participate in the meeting with use of smartphone messengers wherever they are. To make the mobile meeting put to practical use, the mobility and privacy should be ensured to attendees. To satisfy the mobility requirement, the user which is not belong to the group members should not be able to participate in the meeting. To ensure the privacy requirement, the attendees should have not to repudiate the meeting results. In this study, the mobile meeting authentication scheme is proposed which provides mobility and privacy. The proposed scheme consists of meeting group creation, group key generation, group signature and verification protocols. All attendees should have to participate in the signature verification because it is based on the challenge-response type protocol. Thus, it's not possible to collude with malicious attendees to change the meeting results.

Although the amount of UCC(user created content) rapidly grows nowadays, there are various problems in authoring, distribution and management of this abundant content because the platforms for fabrication and replaying content are not compatible and the authoring environments are not sufficiently interoperable with other site or with each other. In this paper, we propose a CMS(content management system) scheme improved in interoperability to solve these problems, and we design a novel system enhancing the efficiency and speed of content distribution and management by minimizing the repetitions in the processes of production, reshaping, and publication. Moreover the proposed system adopts an improved content management technology by changing from simple point-to-point method to the centralized distribution method, and as for the service scheme, we change from the site link method to the database link method, and we also take duplex interlink scheme instead of simplex one. We finally compare the proposed system to the conventional ones as points of view of compatibility and interoperability to prove the improved performance of our system.

The life-time and performance of a wireless sensor network is closely related to energy-efficiency of sensor nodes. In this paper, to increase energy-efficiency, each sensor node operates in one of three operational modes which are normal, power-saving, and inactive. In normal mode sensor nodes sense and transmit data with normal period, whereas sensor nodes in power-saving mode have three-times longer period. In inactive mode, sensor nodes do not sense and transmit any data, which makes the energy consumption to be minimized. Plus, the proposed algorithm can avoid unnecessary energy consumption by preventing transmitting duplicate sensed data. We implemented and simulated the proposed algorithm using Tiny OS based ZigbeX platfom and NS-2, respectively. Performance evaluation results show that the proposed algorithm can prolong sensor networks' lifespan by efficiently reducing energy consumption and its standard deviation of all sensor nodes.

Recently, although the requirement of quality of VOD content has been transferred upto the class of HD, conventional management systems characterized by OS dependency are truly limited in quality of video image, stability, and compatibility of network environments. In addition most of the content management systems realize very limited capabilities for the real affairs of content management and distribution services in such an OS dependent environment. In this paper, we propose a new scheme of HD-Class VOD Content Management System to solve these problems. We design and implement the proposed system based on open sources by using H.264 video compression method. The proposed system offers high quality content management method based on opened systems and independent on-line distribution method so that it can be realized as an integrated management scheme for VOD contents. Moreover, our system solves the problems of occasional cutting-down video, small screen, and poor image quality that exist in the conventional wmv-type CMS. According to the result of performance evaluation, our system maintains sufficient performance and tolerence for the case of large scale HD content operations or fabrications. We expect that the proposed integrated DB scheme will especially be effective when the content management applications are changed from Internet Web environments to mobile terminal environments.

Recently, most of computing technology is based on web. Therefore, the users register web services or needed resources, and they can find and use the registered item. These services can be used alone or can be used in combination. When the item is used in combination, the ordering and association of service is important, and an ontology that defined association of services is required. In this paper, we define association of services based on ontology, and propose a method that can be used by services integration. The proposed method provides an efficient retrieval service by compositing the ontology with the service area and data association area.

To play the networked video contents in a client's mobile device in real time, the contents should be delivered to it by the contents server with streaming technology. Generally, in a server-client based commerce model, the server is in charge of both the authentication of the paid customer and distribution of the contents. The drawback of it is that if the customers' requests go on growing rapidly, the service quality would be degraded results from the problems of overloaded server or restricted network bandwidth. On the contrary, in P2P based networks, more and more the demand for service increasing, the service quality is upgraded since a customer can act as a server. But, in the P2P based network, there are too many servers to manage, it's possible to distribute illegal contents because the P2P protocol cannot control distributed servers. Thus, it's not suitable for commercial purposes. In this paper, the dymanic group authentication scheme is proposed which is suited to P2P based applications. The proposed scheme consists of group based key generation, key update, signature generation and verification protocols. It can control the seeder's state whether the seeder is joining or leaving the network, and it can be applied to hybrid P2P based commerce model where sales transactions are covered by the index server and the contents are distributed by the P2P protocol.

As information security is becoming more important today, efforts in managing information security more efficiently is becoming greater. Each department such as Ministry of Security and Public Administration, Ministry of Science, Ministry of Education, National Intelligence Service, etc. is established screening criteria for information security and conducted the evaluation. Various information security certification and evaluation for public institutions effectively help to improve the level of information security. However, there are limitations of efficient security management because the examination to be performed frequently by each department. In this paper, we analyze screening criteria of the information security management that is being conducted in the public institutions. We also present limitations of information security management and the direction of improving the limitations.

Convergence refers to create a new one by combining the different elements of two or more. Currently convergence has expanded academy, industry and education from the concept of combining heterogeneous inter-technology. The most important key to the convergence in success is to derive ideas for problem solving. However, the idea derivation is done in companies to hire professional people for letting the innovation of corporate planning and new product in most cases. It is hard to get the expected results of convergence's variety. In this research, the creation of the general public for their ideas is main focus on developing a curriculum. Development models are: 1) strengthening the internal capacity for creative thinking, 2) curriculum meets the consumer 3) an understanding of convergence technology 4) creative ideas and planning ability is composed of four concepts. It is expected that convergence man power having the creative idea is trained in case of applying the proposed education model to the convergence education.
