  • National highway is one of the social infrastructures that continue to be managed in order to serve their full functions. The national highway has been managed by the Pavement Management System (PMS) until now. The PMS manages the highway as a way of facility maintenance and maximizes the service life of the highway with minimum cost. The cost is evaluated mainly with a facility manager's perspective based on engineering judgment. People's needs of quality of life have been increased as their income level is rising and naturally the opinion of citizen as a taxpayer plays an important role in determining national policy. Therefore, the contentment of a user's perspective was the starting point of addressing these needs. The Level of Service began to be used as a measure for the evaluation of the user's perspective. In this thesis we would like to design an application and a data architecture for a pavement asset management system and to show how it meets the requirements of KTAM-40 Systems.

  • A firm decides to go to the project based on its investment analysis. However, the cash flows generated from the real project can not be always coincident with what expected as it follows uncertain behavior and the asymmetric payoff caused by the managerial flexibilities involved in the real asset affects the project value. Amongst various managerial flexibilities entailed in most of the real assets, although investment delay has been known to enhance the project value thanks to its ability to provide new market information to management, the related research to select the time to invest have been just few. Therefore, this research aims to show the theoretical framework to decide when to invest reflecting the behaviors of increasing project value and loss recovery cost due to investment delay with option pricing, related financial economic, and variational theories.

  • This study was intended to examine the structural relationship between fan citizenship and sports marketing achievement. For that, 220 questionnaires were distributed to the fans of Lotte Giant in Busan region and 205 questionnaires were used finally. The hypotheses were validated by using SPSS 25.0 and Smart PLS 2.0 based on the study model. All hypotheses were adopted, except for 4 hypotheses(Hypothesis 5-3, Hypothesis 6-1, Hypothesis 6-2, and Hypothesis 6-3), among a total of 17 hypotheses. For that, the results were derived as below: First, fan citizenship had a positive(+) influence on team equity(Hypothesis 1), sponsor assets(Hypothesis 2), and community equity(Hypothesis 3) as a whole. Second, team equity had a positive(+) influence on sponsor assets(Hypothesis 4) in all respects, and furthermore, had a positive(+) influence on local image(Hypothesis 5-1) and contribution to local community(Hypothesis 5-2). Meanwhile, team equity did not have a statistically significant influence on social interchange(Hypothesis 5-3. Finally, sponsor assets and community equity were found to have the relationship as follows: No statistically significant relationship was observed between corporate image and community equity. Corporate awareness had a positive(+) influence as a whole. The results of this study are expected to provide comprehensive understanding and theoretical and practical implications of the influence that fan citizenship would have on sports marketing achievement.

  • This paper suggests several methods of improving information securities of universities through the investigations of the current status of information securities in universities, which is becoming a hot topic in knowledge and information societies. In this paper, universities were randomly selected according to their size, and surveyed through email questionnaire to the persons in charge of security in each university, and 27 universities and 18 colleges were replied. From the survey results we confirmed that the pre-prevention is the most important thing in securing information assets, also in universities, and, in this paper, systematic support must be strengthened to establish a comprehensive security management policy and guidelines for the universities, and the importance of information assets and the necessity of security needs to be shared with the members in the universities. Moreover there must be full administrative and financial support, including recruitment and training of information security professionals and the establishing a separate security division.

  • Product Line Engineering(PLE) is one of the technologies that develop applications economically reusing core assets. PLE consists of Framework Engineering(FE) and Application Engineering. Framework Engineering is to develop core assets that have common functionality shared by a set of family members. Application Engineering is to develop a specific application by instantiating the core assets. The PLE process increases reusability and efficiency because a specific application is developed by using core assets with less time and effort. Since definition of PLE artifacts and relationship between artifacts are not clear. developers have several troubles to make artifacts based on PLE process, are difficult to maintain consistency between artifacts, and do not use PLE process more practically. In this paper, we define meta-models of artifacts that are produced in PLE activities of PLE process and describe the traceability relationship between artifacts by using traceability map and guidelines that can apply traceability relationship. Finally, we define the way how trace links and guidelines of traceability map are applied.

  • Product Line Engineering (PLE) consists of two phases; Core Assets Development and Application Engineering. The core asset development is to model common features of members in a domain and to develop them. The application engineering is to effectively generate an application by instantiating the core asset. Today, PLE research mainly focuses on developing core assets, whereas activities and instructions for application engineering are weakly defined. Moreover, instructions of application engineering are not enough to be practically applied. To widely apply PLE to industry, researches on systematic and practical methods such as instantiation processes, instructions, and artifacts are needed. In this paper, we propose a practical PLE process, instructions, and artifacts about each activity. And then, we also present a case study to show applicability and practicality of the process proposed in this paper.

  • The IT asset is a core part that supports the management objective of an organization, and the fast settlement of the IT asset fault is very important. In this study, a fault recovery prediction technique is proposed, which uses the existing fault data to address the IT asset fault. The proposed fault recovery prediction technique is as follows. First, the existing fault recovery data were pre-processed and classified by fault recovery type; second, a rule was established for the keyword mapping of the classified fault recovery types and reported data; and third, a machine learning process that allows the prediction of the fault recovery method based on the established rule was presented. To verify the effectiveness of the proposed machine learning process, company A's 33,000 computer fault data for the duration of six months were tested. The hit rate for fault recovery prediction was approximately 72%, and it increased to 81% via continuous machine learning.

  • This study was carried out for the purpose of inquiring into the effect of composition and security activities for information security architecture on information asset protection and organizational performance in terms of general information security. This study made a survey on 300 workers in the government, public institutions and private companies, which it showed that management factors of risk identification and risk analysis, in general, have an usefulness to composition and security activities for information security architecture to prevent inside information leakage. And the understanding and training factors of IT architecture and its component were rejected, requiring the limited composition and security activities for information security architecture. In other words, from the reality, which most institutions and organizations are introducing and operating the information security architecture, and restrictively carrying out the training in this, the training for a new understanding of architecture and its component as an independent variable made so much importance, or it did not greatly contribute to the control or management activities for information security as the generalized process, but strict security activities through the generalization of risk identification and risk analysis management had a so much big effect on the significant organizational performance.
