This research analyzed acceptability of local public enterprise management assessment targeting Chungcheongnam-do direct management enterprises. To do this, this research analyzed influence with acceptability of local public enterprise management assessment by composing the area with 5 aspects related to local public enterprise management assessment. More differentiated strategy is required to operate management assessment efficiently, since direct management enterprises have different shape from other public enterprises in respect of organizational structure. In case of water and sewage, it tends to be difficult to return the result of management assessment to the local government organization, so that managers' interest and effort is necessarily required. Also, responsible person's professionalism is required to raise achievement of direct management enterprise through management assessment, politic management plan for this is necessary. Above all, the structure of incentive for management assessment result is difficult in making intended effect as other public enterprises. Therefore, differentiation of compensation system for assessment result is required.

As designing webpage has become part of daily life, the public library tends to use the webpage for the information service and the public relations as well. In this context, this study explores the theoretical background on the webpage of public libraries； investigates and analyzes, based on previous studies, the webpage of public libraries in Seoul in terms of its informations structure and contents : and suggests some recommendations, through designing and controlling, for the effective use of the webpage of public libraries.

As database become more variable and multimedia, the integration between conventional library based on printed matter and digital library on IT makes it accelerated that the changes in today's information circumstances. Due to more leisure time modern people who get intellectual and interested in variety so they need continuing education, intellectual satisfaction and cultural life. Consequently today's public library expands to become a source of every kind of information, an educational facility and community facility to fulfill the cultural needs. On the assumption above, this study aims at offering database for planning public library that meets the needs for multifunctional library through analyzing space, structure, and character of modern public libraries and chooses 8 cases in Japan provide both primary and additional functions. Quantitative data from blueprints, websites and publications has been collected to analyze the space arrangement corresponding with the functional characteristics.

In order to utilize various data provided by Korea public open data portal, data should be systematically managed using a database. Since the range of open data is enormous, and the amount of data continues to increase, it is preferable to use a database capable of processing big data in order to analyze and utilize the data. This paper proposes data modeling and implementation method suitable for public data. The target data is subway related data provided by the public open data portal. Schema of the public data related to Seoul metro stations are analyzed and problems of the schema are presented. To solve these problems, this paper proposes a method to normalize and structure the subway data and model it in NoSQL database. In addition, the implementation result is shown by using MongDB which is a document-based database capable of processing big data.

Adolescent media addiction has emerged as an important social agenda in Korea. However, there has not been enough discussion on the causal structure of media addiction and policy interventions. The objective of this study is to identify and assess the mechanism of the existing and the revised Shutdown policy based on the systems thinking approach. To achieve this purpose, we establish the relationship between media usage, flow, and addiction, and develop a causal loop diagram. Based on the causal loop diagram, we explore the causal structure of two policy scenarios: shutdown policy and deregulation. Our study suggests that policy interventions inducing direct parental control on children's media usage time are ineffective since the time control reduces children's autonomy, which helps alleviate media addiction. Therefore, this study suggests that policy intervention should focus on alleviating addiction itself rather than on controlling media usage time.

We design level 1 traffic thematic map for common data structure. Level 1 means the road that can passing cars. If public office and private company use this form, they can save amount of money from overlapping update. And widely use of traffic analysis, navigation and traffic information system. For design common data structure we compared several data structure(traffic thematic map, ITS standard node/link, Car navigation map), and generalization these characteristic data. After generalization we considered about application parts. It can use of public part(traffic analysis, road management, accident management) and private part(car navigation, map product, marketing by variable analysis) etc.

We propose a method using QFD for design the hierarchical structure of AHP. This method provides definition for each area of House of Quality and design the hierarchical structure of the bottom-up QFD/AHP in which the upper hierarchy is designed through the classification of common characteristics with a focus on the lower hierarchy. Finally, we apply it to the development of an evaluation index for selecting heavy lifting service providers. This study has significance as the first instance of designing the archical structure of AHP after objectively verifying whether MECE condition, the basic requirement for AHP design, is satisfied.

A nonlinear programming model for evaluating public transit fare system is proposed. The model finds transit fare level and the structure that maximizes gross fare-box revenue subject to constraints on minimum ridership and the form of the fare equations. It is assumed that the demand for transit is a function of fare and its own-fare elasticity. It is assumed that the demand for transit is a function of fare and its own-fare elasticity. It is also assumed that the conditions including fare of the other modes are unchanged ; i.e., partial equilibrium. Empirical study has been performed for the case of Seoul subway system. This study includes an analysis of fare structure ; flat system and distance-based fare system. Sensitivity and comperative static analysis for elasticity has been also demonstrated.

The purpose of this paper is to examine the business performance difference based on the ownership structure type in the aspect of profitability and stability. In order to conduct this analysis in two aspects, the ship financial institutions have been classified into two groups: state-owned banks and private-owned banks. First of all, the difference of ROE and ROA between private and public ship financial institutions is statistically significant, but no difference has been shown in terms of stability measured through BIS capital adequacy ratio. Second, to test the business performance difference according to the ownership structure types before and after the global financial crisis, we examined the outcome difference in the ship financial institutions in terms of profitability and stability. However, in the event that the analysis was conducted with public and private financial institutions, the business outcome difference before and after the global financial crisis has been shown in the sector of private financial institutions, but has not been shown in the sector of public financial institutions. It is meaningful that this study is the first work which examined the difference of the operating performance by the ownership structure types of ship financial institutions. However, it is noted that small sample for this empirical study is a limitation of this thesis.
