Seoul Metro Line 9 (SML9) is the first subway line that private capital invests in Korea. SML9 will cross Seoul, linking the Gimpo Airport to the Gangnam district (25.5km) opening in the first half of 2009. SML9 has a new model in Korea constructed by metropolitan government and private company and operated by specialized public transportation service provider. SML9 is confronted with tough environment of stagnated public transportation and strong competitor, Olympic city expressway. And SML9 is under pressure for showing high efficiency as non-governmental organization from both customers and government. Consequently SML9 must lead the maximum efficiency by using its material and human resource. It is necessary that SML9 raise a competitive power and display its ability in active collaboration with relative organization and company. Hereupon, I propose renovation plans from viewpoint of operation field of SML9, (1) efficient train scheduling regime focusing on the combination of express and local train (2) close connection of other mean of transportation and (3) effective connection convention with Airport Railroad (AREX) as the line connected directly.

As cyber attacks become more intelligent, there is difficulty in detecting advanced attacks in various fields such as industry, defense, and medical care. IPS (Intrusion Prevention System), etc., but the need for centralized integrated management of each security system is increasing. In this paper, we collect big data for intrusion detection and build an intrusion detection platform using deep learning and CNN (Convolutional Neural Networks). In this paper, we design an intelligent big data platform that collects data by observing and analyzing user visit logs and linking with big data. We want to collect big data for intrusion detection and build an intrusion detection platform based on CNN model. In this study, we evaluated the performance of the Intrusion Detection System (IDS) using the KDD99 dataset developed by DARPA in 1998, and the actual attack categories were tested with KDD99's DoS, U2R, and R2L using four probing methods.

This paper shows a theoretical-reflective analysis on the importance of vocational training and value education to transition into models that are inclusive in cultural diversity, typical of the globalized and hyperconnected environment of modern societies. Interculturality is contextualized as a key element in linking teaching-learning processes with the uniqueness and problems associated with cultural ethnocentrism and alterity. In this sense, the work is part of a thematic review that contributes to the understanding, inclusion and recognition of cultural, racial and ethnic diversity in the different formal spaces of learning. As summary, value education and transversality are the basis for building educational interculturality in future generations.

Chile has been the first country in Latin America which has built a two-tiered health care system by partially privatizing the health insurance sector. Despite the intial decrease of health expenditure, more researches now show that health inequality within the Chilean health sector has been augmented with privatization of its insurance system. To explore such inequality, this article looks into the impact of privatization of health insurance on women's health. The author argues that privatization has intensified medicalization of women's body and, consequently, it worsened women's health in Chile. This article contributes to a more comprehensive understanding of market-oriented health care reform by linking it with medicalization process.

The construction of National Spatial Data Infrastructure (NSDI) started from 2008 and was completed at 2012, with the aim of co-utilizing public agencies' national spatial information by integrating and linking. Despite the existence of the NSDI, an update of spatial data is not fully reflected because the spatial information has not been updated simultaneously by NSDI and public agencies. By examining the public agencies' services using the spatial information, a national budget is wasted because the re-usable similar services are duplicated. These issues could be solved by adopting a cloud system, whose concept is co-utilizing IT resources, to the NSDI. This study examined the service cloud based expansion and development plan for NSDI. The plan included an implementation strategy for a spatial information service cloud system and an establishment plan for a governance system. The service scenarios, concept diagram, and service functions for the system were derived in a system implementation plan. For the service functions, the unit functions of two modules were proposed and specific functions were derived. In the establishment of a governance system, the business roles and business processes were defined for organizations managing service cloud based NSDI. The business role and process were defined and derived by each service life-cycle step. With the proposed system implementation plan, a detail system design and composition of the organization could be possible, and a service cloud-based NSDI system could be implemented.

This study proposes an Architecture for user level End-to-end Quality of Service(QoS) using overlay In Next Generation Network(NGN). Inexisting NGNs, the IMS of a control plane provides user QoS through direct traffic control and resource-reservation over the IP packet transport network of a user plane. Further, a set of torrent studies are ongoing not only to maximize the QoS for users, but also to minimize the quality deterioration for supporting the user End-to-end QoS. Along with that, an extended QoS in user level must be considered, for Instance, differentiating service quality to support users' expectation, providing optimized contents by users' equipments, and so forth. Accordingly, the Overlay Service Network Architecture proposed by this study provides protocol adaptation for maximum throughput on transport layer by using the most efficient transport layer protocol to various network circumstances. Also, the Overlay Service Network Architecture on application layer distributes processing delay from the data transformation process of the user equipment to the network, and it is capable of intermediate processing depending on user service level. application service feature, and equipment circumstance as well. Thus, this study mainly proposes the Overlay Service Network Architecture for user level end-to-end QoS in NGN with the quality control features both on the transport layer and the application layer, an internal component feature, and a service scenario providing the QoS linking with 3GPP.

The authors of this study conducted research on universities located in China, and the primary purpose of the study was to test whether the quality factors of university education service have a positive (+) effect on student satisfaction. The secondary purpose of the study was to identify and analyze whether university instruction and curriculum variables had a positive regulatory effect on the relationship between quality factors and student satisfaction. First, Research Hypothesis 1, which suggested that university education service quality factors would have a positive effect on student satisfaction, was adopted. As the second analytical process of the study, controlled regression analysis was used to verify whether instruction and the curriculum had a regulatory effect on the relationship between the university education service quality factors and student satisfaction. When the two variables were analyzed as control variables, the results showed that curriculum had a significant positive regulatory effect, and instruction was shown to not be suitable for generating win-win cooperation or synergistic effects. The contributions of the theoretical perspective of this study were the analysis of the relationship between university education service quality factors in Chinese universities and student satisfaction, and systematically linking instructions and the curriculum and analyzing the impact on student satisfaction. The study implies that it would be more effective to analyze additional factors in the operation of universities through in-depth analysis on instruction from a practical standpoint.

The Advent of the global information structure and the do-called digital revolution raise countless new issues and questions. There are no limitations regulating the expressions on the cyberspace due to internet's of quality anonymity\ulcorner diversity\ulcorner spontaneity. Therefore, the freedom of speech is expanded in both areas of time and space, which was impossible with the old communicating system. The rapid development of the internet may not have occurred without techniques of linking and framing, which provide users flexible and easy access to other website. These techniques have enabled internet users to navigate the internet efficiently and sort through the products, services and information available on the internet. Although online technology raises many new legal issues, the law available to help us resolve them, at least today, is largely based on the world as it existed before online commerce became a reality. Thus the challenge is to predict how these new legal issues may be resolved using the current law. Especially, the damage from the above side effects on the cyberspace can be much more serious than in the real world because of promptness, wideness and anonymity. Therefore, regulating and controling the freedom of speech on the cyberspace became needed, and there are two kinds of opinion; one is that the laws in the real world should be applied for the cyberspace and the other is that regulating and controling the freedom of speech on the cyberspace should be performed by the users of cyberspace not by laws because the cyberspace is a free space and must not be interfered. In this study, the current judicial regulation of cyberspace, the side effects of cyberspace and the limitations of the freedom of speech are studied to solve the above problems with speech and the liabilities of on-line service providers are discussed around defamation the distribution of obscene pictures and information, and infringement of copyright.

For successful projects, Project Management Information System(PMIS) using the formal systematic processes is necessary. Because the existing PMIS focuses on low-level project management, the life-cycle administration of the projects is required. In this dissertation, I describe not only the processes for managing a project with the top-down approach(a hierarchical goal setting of the project outcome), but also PMIS which can control whole processes of R&D projects. The PMIS described in this dissertation can reduce the workload of project management by providing user-adaptive environments and linking with related systems, so can be helpful to enhance the efficiency of the project management. And, it is expected that these processes can be the standard project management processes which are adaptive to various types of projects.
