Existing tools using in the standard e-learning contents authoring were used a method to provide users contents template produced in advance. In order to use resources of the template in a common web-based authoring tool, there is problem to overcome. If the resource of template is inserted within the contents on the authoring tool, the deformation of the template by the user's input that may occur during the edit process cannot be controlled. In this paper, we propose an effective maintenance method to prevent deformation of the resource of template inserted into any WYSIWYG-based HTML authoring tool by user's discretion. We added a template plug-in that can create the IMS-QTI standard resource in tynyMCE the web-based open source editor of representative examples. And the plug-in for tinyMCE was realized as a module of directly respond to the action of limited user input. So, in response to the action of user's input, the structure of the template can be sustained possibly.

In order to solve the current problems and inefficiencies within the Port Authorities (PA) in Korea, this study introduces the concept of the integration of PA and analyses the awareness of intention of integration. This study is based on analysing the surveys conducted by the members of PA. This research shows that there were different perceptions on the autonomy, business strategy intension, information sharing efficiency, competition, environment and technique change, capital finance, easy finance risk, curtailment of expenditure, personnel management efficiency in PA. Results of the study indicate that YGPA has more clear understanding on the awareness of integration of PA than other PAs. The results of this research will serve as a basic literature for further studies on the integration of PA in Korea. Moreover, the problems that have been identified and analysed in this study will contribute to establishing the strategy for further development of PA in Korea.

Bluetooth is a communication technology enabling short-range devices to be wirelessly connected. A master and one or more slave devices are connected to form a piconet, and piconets are joined to form a scatternet. The units participating in two or more piconets in a scatternet, is called bridge or gateway nodes. In order to operate the scatternet efficiently, both piconet scheduling for the master and slaves of a piconet, and scatternet scheduling for the bridge nodes are playing important roles. In this paper, we propose a traffic-adaptive dynamic scatternet scheduling algorithm based on rendezvous points and rendezvous windows. The performance of the proposed algorithm is compared and analyzed with that of a static scheduling algorithm via simulations. Simulation results show that our algorithm can distribute wireless resources efficiently to bridge nodes depending on the traffic characteristics.

It is important to integrate an enterprise application for automating of the business process, which is responded by a flow of market environment. There are two categories of method that integrate enterprise applications. One is Synchronous Integration, and the other is Asynchronous Integration. EAI(Enterprise Application Integration) and Web service which of the asynchronous integration is focused in the automating method of the business process. After we construct the application integration for automating of the business process, we have to concern about managing of the business transaction. Many Organizations have proposed the process method of business transaction based on 2-phase commit protocol. But this method can't supply the phase that classify the transaction by transaction weight. In this Paper, we Propose an efficient method of transaction process for business transactions, which is composed by ‘Classify Phase’ that classify transactions. We called this model “3-Phase Commit Method Applied by Classify Phase”, we design this model to manage an resource of enterprise efficiently. The proposed method is compared by the method based on 2-Phase commit that could be a problem of management the resource of enterprise, and the advantage of this method is certified to propose the solution of that problem.

Recently there is show deep concern at the wellness of health and beauty. therefore this study is to investigate an empirical study on the relational characteristics and collaboration between wholesalers and oriental clinic in herb medicine supplier channel, specially focused on lycium chinense. We collected statistically usable data from 119 questionnaire respondents who live in national provinces and analyzed them with SPSS 20.0 to achieve research's goals. Analysis results revealed that, first, relational characteristics of relationalism, trust, reward power and dependence had impacts on satisfaction between wholesaler and oriental clinic in herb medicine, Second, the survey found that satisfaction has impact on collaboration. Third, this study partially supported mediating effect regarding satisfaction between relational characteristics of relationalism and reward power.

The virtualization layer is executed in higher authority layer than kernel layer and suitable for monitoring operating systems. However, existing virtualization monitoring systems provide simple information about the usage rate of CPU or memory. In this paper, the monitoring system using full virtualization technique is proposed, which can monitor virtual machine's dynamic kernel object as memory, register, GDT, IDT and system call table. To verify the monitoring system, the proposed system was implemented based on KVM(Kernel-based Virtual Machine) with full virtualization that is directly applied to linux kernel without any modification. The proposed system consists of KvmAccess module to access KVM's internal object and API to provide other external modules with monitoring result. In experiments, the CPU utilization for monitoring operations in the proposed monitering system is 0.35% when the system is monitored with 1-second period. The proposed monitoring system has a little performance degradation.

Because the specific security technology alone can not cope with sophisticated attacks, various security management models are applied. But, they do not focus on the vulnerability of the highest part because they offer so many common security management criteria. By analyzing the main information and confidential leakage cases inflicting enormous damage to our society, we found that attackers are using mainly an interface vulnerabilities - the paths that connect the internal and external of the organization, such as e-mail, web server, portable devices, and subcontractor employees. Considering the reality that time and resources to invest in security domain are limited, we point out the interface security vulnerabilities the possibility of attackers to exploit and present a convergence method of security measures. Finally, based of ROI(Return on Investment), we propose the real-time security management system through the intensive and continuous management.

The Chos$\hat{o}$n society witnessed internal unrest that culminated in popular uprisings during the years of 1700~1870, and this circumstances in Korean society offered a good opportunity to reorganize the relationship between production and society. However, it is not clear whether this pointed toward a modern capitalist society. Nevertheless, Korean society and agriculture developed under various difficult circumstances. In the view of the increase of land productivity and population during this period. Despite such tribulations, alter WWII the country underwent rapid industrialization, but it is not clear how lar the historical experience aided this development. The educational investment which builds upon the peasants' work morale and thriftiness certainly transforms the human capital and thus exerts important influence on the development of Korean modernization.
