Currently many companies have realized that producing efficient product does not guarantee the market differentiation. Realizing the problem, those companies are actively pursuing the servitization strategy. However complexities in selecting the right service areas among many choices along with in developing service strategies and organizational structures remain unsolved to many manufacturing companies. This paper is about an exploratory study in which, through in-depth case analysis, we observed how a manufacturing company successfully managed to transform to the service company. Through this study, we have found that successful transformation needs to resolve many conflicting issues such as channels among existing and new sales front, organizational restructuring due to conflicting in evaluation and human resource requirements required for responding to customers in the field. This 'Hansam' case study provides managers with some guidelines as to how to transform to the service company.

With the development of information technology, users can freely search records and archives without the involvement of archivists. However, existing records retrieval systems show only partial search results, which do not consider the users' intention. To overcome this problem, semantic web technology is being developed, and the International Council on Archives (ICA) is working to develop RIC (Records In Context), a new archival description standard, which reflects the trend. The conceptual model for archival description and its ontology of RIC are the basis for implementing semantic-based retrieval. In other words, it is necessary to consider the viewpoint of the users on how the records retrieval based on meaning should be designed and provided. Therefore, this study selected three cases of systems, which are built as semantic web technology, and conducted interviews of the users for the evaluation of the systems based on user experience. This study proposes the kind of interface that can be implemented for the ontology-based record retrieval system.

Artists use artistic features of paintings to provide various emotions in paintings. These features may be simply color and texture, but they can move on to form a composition or a symmetry. Through these features, people can feel various emotions when enjoying paintings. Even though they are using these features, there are paintings that are not readily accessible to non-extractable experts. This is because the analysis of features is not intuitive. In this paper, we want to produce content that matches paintings and music. This helps user to understand painting easily with paintings and matched music.

Meta-evaluation for national R&D programs should be established within the framework of whole R&D system linked with science and technology needs and objectives. The R&D program evaluation system can be understood as a circulation of input, implementation, output, and utilization. In the result of the Delphi survey, which consisted of twenty-four experts (performed in three rounds), twenty-four indices were developed. The meta-evaluation model included sub-items which were important points of view of it as follow (eight items): propriety of planning, sufficiency of information, and propriety of evaluators in evaluation input; appropriateness of method and appropriateness of procedure in evaluation implementation; credibility of output in evaluation output; and usefulness of report and application of evaluation utilization. As the application of the meta-evaluation model, the total mean was lower than 3.0 of the median value of 2.73 (5 point Likert scale). Finally, it was suggested that the feedback of evaluation results should be more enforced to R&D program improvement particularly (evaluation utilization 2.50).

Resource development is needed in order to develop the industry. However, because resources are running out, there is a growing interest in the arctic regions. If you want to develop resources in cold regions, it is necessary to understand the environment there and it should be a priority to secure proper technology for construction. In particular, thaw settlement, which frequently occur in Arctic regions, have a fatal effect on essential pipeline needed to transport resources. Therefore, it is important to analyze how piping will be impacted by thaw settlement. In this study, we developed 3-D FEM model in order to analyze the influence of the buried depth of the pipe at the time of thaw settlement. We analyzed a displaced pipe which is subjected to stress and considered Elasto-plastic, using the finite element analysis according to these Arctic environments.
