The ship without thrusters and special propulsion system is supported by the tug boats during berthing and unberthing. The orders to tug boats are made by a pilot. If the positions of ship, tug boats and port are displayed in 2D map, it will be helpful to pilots. In this research, a network-based pilot supporting system(NPSS) has been conceptually designed NPSS, necessary for safe and efficient pilot, has two main functions. One is the monitoring of the situation of berthing and unberthing. And the other is the automatic calculation of the tug forces considering environmental conditions. The NPSS is designed on the basis of network system around the harbor. The NPSS will be validated using ship-handling simulator in the future.

The regional strategic industry support has been increasingly developed due to the change of environmental and political conditions for the last 10 years. As the paradigm changed from the central government-sponsored system to regional government-sponsored system, the policy has been diversified into various support systems such as regional strategic industry, specialized industry, supporting technology, supporting business, etc. It is crucial to establish the overall development plans and project strategies for the regional industry in terms of effectiveness and efficiency which will generate an integrated strategic frame to adjust overlapped supporting policies and offer a consumer-oriented service. Not only does the study focus on performance-based outcome regarding to a regional business (supporting policy) portfolio, but it also analyzes and proves an empirical decision-making model to draw out the priority and relative importance according to the regional strategic industry and support cases by analyzing the case of Chungnam area's strategic industry support in 2009. Following a priority list of 20 support cases selected from this research model by the Analytic Hierarchy Process (AHP), the result shows that the diverse support plans are needed according to the different strategic industries or the size of enterprise due to the fact that priority of project type varies upon the characteristics of strategic industry. Thus, the support project needs to generate various strategic industries and develop differentiated support policy to consolidate competitiveness of regional enterprises and revitalize the regional economy.

The 2015 revised national curriculum has been implemented to first year students in elementary school, and will be expanded to middle school and high school from next year, 2018 school year. As of this year, the ways of implementing the curriculum and supporting teachers to better implement the curriculum into their classrooms are crucial. This study explores the implications for building curriculum supporting and implementing system by investigating relevant systems in foreign countries, such as Australia and England. In order to achieve the purpose, this study conducts literature review and previous studies in regards to the curriculum implementing and supporting system, interviews with curriculum developers and teachers, and analyzes their web-sites of the two countries. The results shows that active communication is essential among curriculum developers and curriculum implementers including school teachers and other stake-holders, and this communication can be achieved by building systematic ways; second, professional development for teachers should be recommended by supporting integrated and systematic teaching-learning process; third, the principal agent for curriculum implementation, school teachers, should have the autonomy for implementing the curriculum. The detailed ways for realizing the three implications are suggested.

Organizations are investing in information systems for an ever-increasing number of end-user tasks. Extracting benefit from these investments increasingly depends on supporting effective use or information center and satisfying information center users. Information center is information intensive and the use of advanced technology may support user for delivering an unique capabilities in an organization. Information center represents an important source which seems very well suited for end-users support investigation. This research explores the end-user support factors that correlate with user satisfaction in information center. To exam user satisfaction, information supporting, service reliability, and system capabilities were identified as potential predictors of end-user support satisfaction at information center. Three hypotheses have been tested with the survey or 252 end-users examines 18 potential end-user support factors such as information supporting, service staff attitude, and system capabilities at information center. Service quality gap between perceived Importance and performance for each support factor, is computed. The relationship between these service quality gaps and user satisfaction are tested. This study presents that the level of information supporting, service reliability, and system capabilities are significantly to user satisfaction, and it is influenced by the extent of service quality gap between perceived importance and performance for each support tactor.

Currently, all design information of a hull structure is being first defined on 2D drawings not 3D CAD model at the initial ship design stage and then transferred to following design stages through the 2D drawings. This is caused by the past design practice, limitation on time, and lack of hull structural CAD systems supporting the initial design stage. As a result, the following design tasks such as the process planning and scheduling are being manually performed using the 2D drawings. For solving this problem, a data structure supporting the initial design stage is proposed and a prototype system is developed based on the data structure. The applicability of the system is demonstrated by applying it to various examples. The results show that the system can be effectively used for generating the 3D CAD model of the hull structure at the initial design stage.

In this study we developed an ontology-based e-learning system for supporting self-directed learning. In this system, a domain ontology of a learning topic was constructed and relation properties were defined to indicate the relations among the learning concepts. The learning concepts and their relationships are structured visually through the domain ontology. It also boosts understandabilities of students by means of the visualization of relationships among the pre and post concepts. In addition, the system provides reasoning so that learners can do intelligent query when they want to learn more or they are curious about the high-level knowledge while they are learning a topic. These features of the system would help learners' self-directed and active learning.

In cluster file systems, the availability of files has been supported by replicating entire files or generating parities on parity servers. However, those methods require very large temporal and spatial cost, and cannot handle massive failures situation on the file system. So we propose HA-PVFS, a cluster file system supporting high data availability adaptive to temporal locality. HA-PVFS restricts replication or parity generation to some important files, for that it employs an efficient algorithm to estimate file access patterns from limited information. Moreover, in order to minimize the performance degradation of the file system, it uses delayed update method and relay replication.

This paper proposes a geospatial data visualization system supporting validation of GML documents. GIS systems manage and use both of spatial and non-spatial data. Currently, most GIS systems represent spatial data in GML (Geography Markup Language) developed by OGC. GML is a language for representation and sharing of spatial information, and until now many systems have been developed in GML. GML does not support expression of non-spatial data, i.e., relational information of spatial objects, and thus most systems extend GML to describe non-spatial information. However, it causes an issue that the systems only accepting standard GML documents cannot process the extended documents. In this paper, we propose a new GIS data visualization system to resolve the aforementioned Issue. Our proposed system allows the representation of both types of data supporting independency of spatial data and non-spatial data. It enhances interoperability with other relevant systems. Therefore, we can develop a rich and high Quality geospatial information services.

In the last two decades, the welfare states have undergone the changes of restructuring towards two ways. One is a restructuring of workfare and the other is a restructuring of the gender model of welfare state. In Korea, the workfare is reflecting on the DJ Welfarism 'Productive Welfare', but the gender model has a little effect on the public policies. By the way, It is imported that has the gender perspective in approaching the self-supporting program in the public assistance representing of the DJ Welfarism. Because almost 60% of the beneficiaries of the program are women. The Gender-mainstreaming strategy criticizes for the laws, the public policies, the public programs that considered gender-neutral or gender-blinded, and then complete the equality between women and men through the modification or development of those. The approach of Gender-mainstreaming is very important strategy for not only women who are self-reliance recipient but also successful settlement of self-supporting program. Nowadays that program is not execute yet. Then we hardly have information about recipients and the results that expected from that. At this point of gender-mainstreaming, this report suggest the strategy to development and settlement of the self-supporting program in the basics of analysis for the low-income unemployed and the government policy response to unemployment. For the gender models of the self-supporting program, the most important thing is throwing the male breadwinner model and adoption the dural-earner model (the gender model) about that program. Then we must produce gender-statistics data, develop programs for public work, job replacement, job training, evaluating system, etc. with gender perspective.
