Shipbuilding is basically labor-intensive industry. It creates a number of job opportunities, but it is classified as a high risk industry like the construction industry. Shipyards show similarities in many aspects compared with the construction sites. There are many stakeholders of the HSE managements in the shipbuilding industry, such as ship owner, primary contractor and multi-layered subcontractors. The ship owners who are almost foreigners are treating strictly about safety and health. Therefore, it is necessary to development an appropriate HSE management systems and for the management systems it is desirable to information technology (IT) to accommodate these complex and complicated problems and situations. It was developed the ISP (Information Strategic Planning) as a HSE management system for the shipbuilding industry. It consisted of the environment analysis, the As-Is analysis and the To-Be design. In this study, the ISP is introduced and further it is suggested that it should be connected to system of HR(Human resource), PM(Plant maintenance) and KM(Knowledge Management) to make the HSE management system efficient.

By reclassifying and reinterpreting the factor variables that were used in precedent studies on company informatization by research theme and perspective on them success factor, the present study tried to examine how different the factor variables are in frequency of use and by period, and how importantly they were considered by research theme and perspective on its success factor, combining them with the studies done on mechanism point of view. The key findings of this study are as follows. First, it was found that the frequency of using mechanism variables, which are reclassified based on SER-M perspective, has gradually increased since 1990s. While the frequency of using resource factors sharply increased in 1990s, it decreased from 2000s. It indicates that more studies were conducted of mechanism factors other than resource factors from the early 2000s. Second, when looking at those variables reclassified by research them, it was found that such theme as decision maker, environment, and resource factors were more used than other research themes in the studies on the measuring factors of informatization. Mechanism factors turned out most used among overall research themes. In particular, they were more frequently used in studies related to the performance of informatization. This result evidences that mechanism-related variables are more importantly considered in the studies than other factors. This study produces a practical implication: what factors companies have to manage and secure intensively to attain successful informatization. In addition, this study helps companies seeking informatization understand and take advantage of SER-M factors on the basis of knowledge in the transitional process of the factor variables used in studies by period. It is expected that CIO can use the key findings of this study in monitoring the factors by the stage of informatization.

In the computing environment with heterogeneous resources, a job scheduling model is necessary for effective resource utilization and high-speed data processing. And, the job scheduling model has to cope with a dynamic change in the condition of resources. There have been lots of researches on resource estimation methods and heuristic algorithms about how to distribute and allocate jobs to heterogeneous resources. But, existing researches have a weakness for system compatibility and scalability because they do not support the standard language. Also, they are impossible to process jobs effectively and deal with a variety of computing situations in which the condition of resources is dynamically changed in real-time. In order to solve the problems of existing researches, this paper proposes a semantic computing-based dynamic job scheduling model that defines various knowledge-based rules for job scheduling methods adaptable to changes in resource condition and allocate a job to the best suited resource through inference. This paper also constructs a resource ontology to manage information about heterogeneous resources without difficulty as using the OWL, the standard ontology language established by W3C. Experimental results shows that the proposed scheduling model outperforms existing scheduling models, in terms of throughput, job loss, and turn around time.

In the service-oriented economy, knowledge and skills are considered core resources to secure competitive advantages and service innovation. Knowledge management capability, which facilitates to produce, share, accumulate and reuse knowledge, becomes as important as knowledge itself to create service value. Along with knowledge management capability, dynamic capability and operational capability are the key capabilities related to managing service delivery processes. Previous studies indicated that these three capabilities are related to service innovation. Although separately investigate the relationship between the three capabilities. The purpose of this study is 1) to define variables that have effects on service innovation including knowledge management capability, dynamic capability and operational capability, and 2) to empirically test to identify relationship among variables. In this study, knowledge management capability is defined as the capability to manage knowledge process. Dynamic capability is regarded as the firm's ability to integrate, build, and reconfigure internal and external competences to address rapidly changing environments. Operational capability refers to a high-level routine that, together with its implementing input flows, confers upon an organization's management a set of decision options for producing significant outputs of a particular type. The proposed research model was tested against the data collected through the survey method. The survey questionnaire was distributed to the managers who participated in an educational program for management consulting. Each individual who answered the questionnaire represented a knowledge based service firm. About 212 surveys questionnaires were sent via e-mail or directly delivered to respondents. The number of useable responses was 93. Measurement items were adapted from previous studies to reflect the characteristics of the industry each informant worked in. All measurement items were in, 5 point Likert scale with anchors ranging from strongly disagree (1) to strongly agree (5). Out of 93 respondents, about 81% were male, 82% of respondents were in their 30s. In terms of jobs, managers were 39.78%, professions/technicians were 24.73%, researchers were 12.90%, and sales people were 10.75%. Most of respondents worked for medium size enterprises (47,31%) in their, less than 30 employees (46.24%) in their number of employees, and less than 10 million USD (65.59%) in terms of sales volume. To test the proposed research model, structural equation modeling (SEM) technique (SPSS 16.0 and AMOS version 5) was used. We found that the three organizational capabilities have influence on service innovation directly or indirectly. Knowledge management capability directly affects dynamic capability and service innovation but indirectly affect operational capability through dynamic capability. Dynamic capability has no direct impact on service innovation, but influence service innovation indirectly through operational capability. Operational capability was found to positively affect service innovation. In sum, three organizational capabilities (knowledge management capability, dynamic capability and operational capability) need to be strategically managed at firm level, because organizational capabilities are significantly related to service innovation. An interesting result is that dynamic capability has a positive effect on service innovation only indirectly through operational capability. This result indicates that service innovation might have a characteristics similar to process innovation rather than product orientation. The results also show that organizational capabilities are inter-correlated to influence each other. Dynamic capability enables effective resource management, arrangement, and integration. Through these dynamic capability affected activities, strategic agility and responsibility get strength. Knowledge management capability intensify dynamic capability and service innovation. Knowledge management capability is the basis of dynamic capability as well. The theoretical and practical implications are discussed further in the conclusion section.

Priority-based network service has been widely adopted for the Internet traffic management in the context of IETF differentiated services, and computing optimal prices for such priority-based service is the key topic in many pricing literature. While the equilibrium analysis has been commonly used to this end, many have criticized the validity of the underlying assumption of equilibrium analysis that user utility functions are precisely known. In this paper, we propose a solution for bridging the gap between the existing theoretical work on optimal pricing and the unavailability of precise user utility information in real networks. In the proposed method, the service provider obtains more and more accurate estimates of user utility functions from the initial imprecise knowledge by iteratively changing the price of service levels and observing the users' decisions under the changed price. Our contribution is two-fold. First, we have developed a general principle for estimating the user utility functions. Second, we have developed a novel method for setting the prices that can optimize the extraction of the knowledge about user utility functions. The extensive simulation results demonstrate the effectiveness of our method.
