Annual IT budget of major companies in South Korea is 44.7 billion Korean Won on average in 2007. A survey shows that among these companies, 58% of them had decided to increase the budget compared to that in previous year. In this study, we investigate relationship between IS investment goal and IS performance with moderating effect of process for IS infrastructure maintenance. For this purpose, we used a set of data with 271 responses gathered from manufacturing industry in 2006. Our results show that the relationship exists but varies across the task characteristics and there's no moderating effect. This finding implies that practitioners should be aware of that different goals need to be established based on task characteristics and more effort to harmonize the process with task activities is required to them.

Cooperative query answering is a research effort to develop a fault-tolerant and intelligent database system using the semantic knowledge base constructed from the underlying database. Such knowledge base has two aspects of usage. One is supporting the cooperative query answering Process for providing both an exact answer and neighborhood information relevant to a query. The other is supporting ongoing maintenance of the knowledge base for accommodating the changes in the knowledge content and database usage purpose. Existing studies have mostly focused on the cooperative query answering process but paid little attention on the dynamic knowledge base maintenance. This paper proposes a multi-level knowledge representation framework called Knowledge Abstraction Hierarchy (KAH) that can not only support cooperative query answering but also permit dynamic knowledge maintenance. The KAH consists of two types of knowledge abstraction hierarchies. The value abstraction hierarchy is constructed by abstract values that are hierarchically derived from specific data values in the underlying database on the basis of generalization and specialization relationships. The domain abstraction hierarchy is built on the various domains of the data values and incorporates the classification relationship between super-domains and sub-domains. On the basis of the KAH, a knowledge abstraction database is constructed on the relational data model and accommodates diverse knowledge maintenance needs and flexibly facilitates cooperative query answering. In terms of the knowledge maintenance, database operations are discussed for the cases where either the internal contents for a given KAH change or the structures of the KAH itself change. In terms of cooperative query answering, database operations are discussed for both the generalization and specialization Processes, and the conceptual query handling. A prototype system has been implemented at KAIST that demonstrates the usefulness of KAH in ordinary database application systems.

With the development of the American Customer satisfaction index (ACSI), research on customer satisfaction measurement or evaluation methods have become significant in the last decade. Most of international customer satisfaction barometers or indices are evolved based on the cause and effect relationship model of ACSI. Of critical importance to validity of customer satisfaction indices is how to construct a measurement attribute or indicator model and provide an effective implementation method effectively. Quality Function Deployment (QFD) is a very useful tool for translating the customer voice into product design through quality engineering. In fact, this is a methodology for measuring and analyzing evaluation indicators by their relationship matrix. In this paper, we will make an effort to integrate the framework of QFD into the measurement problem of customer satisfaction, and also develop a new multi-phase QFD model for evaluation of Customer Satisfaction Index (CSI). From the houses of quality in this model, the evaluation indicators impacting on customer's global satisfaction are identified by means of their relationship matrix. Then the evaluation indicator hierarchy and its measurement method for the customer satisfaction index are presented graphically. Furthermore, survey data from the Chinese automobile maintenance sector and a relevant case study are utilized to show the implementation method of the QFD model used to measure and analyze of customer satisfaction.

As the portion of information systems (IS) budget to the total government budget becomes greater, the cost estimation of IS development and maintenance projects is recognized as one of the most important problems to be resolved for scientific and efficient management of IS budget. Since IS budget makes much effect on the delivery time, quality and productivity of IS projects, the exact cost estimation is also necessary for the successful accomplishment of IS projects. The primary concern in the cost estimation of IS projects is software cost estimation, which requires the measurement of the size of softwares. There are two methods for sizing software : line-of-code approach, function point model. In this paper, we propose a function-point-based model for estimating software cost. The proposed model is derived by collecting about fifty domestic IT projects in public sector and analyzing their relationship between cost drivers and development effort. Since the proposed model is developed by simplifying the function point model that can be used only when detailed user requirements are specified, it can be also applied at project planning and budgeting phase.

Objectives : The purpose of this study was to examine whether the subjective oral health awareness and oral health behavior of Korean adults would affect their oral health indexes. It's meant to utilize existing data of epidemiological and alternative indexes in an effort to have a comprehensive and understanding of the relationship between the subjective oral health awareness and oral health behavior of Korean adults. And the following findings were obtained Methods : The subjects in this study were 7,285 adults who were selected from the third-year(2009) raw data of the fourth national health & nutrition survey. Results : As for the relationship between oral health awareness and oral health indexes, there were statistically significant differences in DMFT index, FS-T index, T-health index and CPI index according to self-rated health status, self-rated oral health state, necessity of dental treatment and oral health concern. Concerning the relationship between oral health behavior and the oral health indexes, whether they got a dental checkup over the past year, daily toothbrushing frequency, use or nonuse of oral health supplies and mastication problems made statistically significant differences to DMFT index, FS-T index, T-health index and CPI index. The variables that had a significant impact on oral health were selected from among the variables of oral health awareness and oral health behavior that affected oral health, and the variables were selected as independent variables. And then the oral health indexes were selected as dependent variables, and a multiple regression analysis was carried out by using the selected independent and dependent variables. As a results, it's found that the variables made a 22.4% prediction of DMFT index; 51.3% for FS-T index; 52.0% for T-health index; 47.4% for CPI index. Conclusions : The above-mentioned findings illustrated that the relationship between the subjective oral health awareness and oral health behavior of the Korean adults exercised an influence on their oral health indexes. Accurate and effective oral health plans should be mapped out by grasping the oral health status of adults from diverse angles to facilitate the maintenance and promotion of their oral health status.
