Mobile Communication Companies are trying to increase data services rather than telephone communication services that already became saturated as the competition of mobile communication market gets intensified. However, it is hard and time-consuming for customers to find desired mobile phone wireless services because of the limitation of screen and speed of the mobile phone. Therefore, the market does not grow rapidly as mobile communication companies expected. In our research, we suggest a personalized wireless service recommendation system that considers each individual context by using geographic information and wireless internet usage logs to overcome the mentioned problems. In order to design and implement the system, we conducted clustering analysis on base stations and real service usage logs of each base station, and suggested a personalized recommendation system based on collaborative filtering that uses the clustering results. Moreover, we verified the performances of our system with experiments.

The Journal of Society for e-Business Studies, volume 15, issue 2, 2010, Pages 19~35
In response to an increased need, various methods for ontology modularization have been proposed. However, few studies have focused on evaluative methods for ontology modules. In this study, we devise novel metrics to measure ontology modularity. To evaluate the ontology modules, we introduce cohesion and coupling based on the theory of software metrics. A cohesion metric and two coupling metrics were used to measure cohesion and coupling for ontology modules. These metrics were also used to check consistency between the ontology modules and the original ontology. The new metrics support a more detailed relationship between classes in ontology modules. We validate the proposed metrics using the well known verification framework and perform the empirical experiments to complement previous investigations. This study offers ontology engineers valuable criteria with which to select and use ontology modules and modularization techniques.

As mobile communications service is growing every single year in Korea, it has pulled the interest of many researchers as wells as the executives. This research is aimed to find out factors of the mobile market that affect the utilization of mobile communication. We adopted a survey method with a pinpointed focus on how users' profile and individual experience relates with the utilization of mobile communication. For this objective, first, we primarily analyzed the mobile users' characteristics and service usage patterns. Then, we developed a conceptual model and hypotheses that are empirically examined using a covariance structure analysis, which will contribute to investigating critical success factors in mobile business. Some suggestions constitute the remaining part of this research. First, user characteristic is an important factor that affects the amount expended for mobile service. Second, user experience is another critical aspect that is highly linked with mobile payment. In alignment with our research, we propose user characteristics such as age and income, and user experience about mobile internet usage and mobile contents usage are of great significance in devising both near- and long-term mobile business strategy.

The primary purposes of this study are to find a proper model for government's selections of Mainbiz and present what are the better weights of the current indexes. We prepared three sets of models：first one using original 10 variables; second one using 9principally composed variables; third one using 7 principally composed variables. Among 3 models, the last one had higher explanation power than the other two models. Therefore, if index weights are adjusted according to the third newly developed model, the credibility in evaluating and selecting Mainbiz will be improved. When transforming the index weights and running the analysis, 5 variables(organization process, marketing management, management process, production-facility states, the level of forecasting) have more direct influences than other 4 variables(innovation strategies, knowledge management, achieving level, operational level) on selecting Main-biz.

Recently, rapid economic growth has brought side effects with it such as environmental pollutions. As a result, 'Green IT' emerges as a solution to these problems. With providing clue for solving environmental problem, Green IT also has been focused as an emerging growth power which could enhance the IT industry activity. In Korea, most part of energy consumption depends on import. Moreover, an economic structure also indicates high degree of dependence upon export. Therefore, based on IT that has competitive advantage, we need to preoccupy with green IT market. In this regard, we research the status of promoting for IT in domestic and major countries. Especially, this paper focuses on government policies and companies strategies.

The Journal of Society for e-Business Studies, volume 15, issue 2, 2010, Pages 93~105
Address and location information is gaining importance as a channel between business entities and customers. However, as the new address scheme, which is based on street name and building number, is deployed, various problems occurred in the areas of postal service, logistics and management of customer information. And therefore it is necessary to make plans for integration and application of address information and location information. In this study, we clearly identify the problems when the governments and companies manage the address and location information under the circumstances of new address system. And we suggest improvement plans from the viewpoint of code scheme and database linkage.

Nowadays many telecommunication service companies try to enhance the quality of their service by providing customers with more specialized service for greater customer satisfaction. As this trend continues, the role that frontline employees play is getting more and more important because they are the ones who have direct influence on customers. For this reason, more than ever, the role of call center has become of paramount importance. Noting that a call center employee's job satisfaction critically affects the quality of service that a customer gets, this study was carried out in order to provide an insight on effective personnel and performance management which can boost up the job satisfaction of a call center employee, thereby enhancing the productivity of Call Center. Conclusively, it verifies that among job satisfaction influence factors, superior's support and compensation fairness indeed have a tremendous influence on job satisfaction of a call center employee. Furthermore, it verifies that if a call center employee is satisfied with his or her job, he or she tends to work more efficiently and hence increase productivity.

A virtual team is defined a group of people that use electronic communications for some or all of their interactions with other team members. Because team members of a virtual team are physically and temporally distributed, a team's transactive memory system(TMS) is considered to be crucial for the team's effectiveness and performance. TMS refers to a set of individual memory systems which integrate knowledge possessed by particular members through a shared awareness of who knows what. This paper seeks to understand (1) how a virtual team's TMS influences team performance, and (2) what factors contribute to developing the team's TMS. Given these purposes, through the extensive literature review, we first identified components and antecedents to develop a theoretical model that predicts a virtual team's performance. Using the survey data gathered from 172 virtual teams, this study found that expertise location, coordination, and cognition-based trust which were proposed as three components of TMS positively influenced a virtual team's performance. Furthermore, this study uncovered that perceived media richness, network tie strength, and shared norms significantly influenced the components of TMS, while geographical dispersion did not exert any significant influence on TMS.

As adopting ubiquitous technology into civil engineering, new city model is suggested called U-City. This paper proposes the framework of U-City management center to support effective services operation. The aims of the framework are to provide the development and operation environment for U-City services. Basically, these objectives are achieved by adopting the semantic web service technology to the framework. In this paper, OWL-S is mainly conducted to represent the description of U-City services. In addition, this paper insists that fine grained unit services are required to guarantee reusability, compatibility, and scalability of the services on U-City management center. The documentations conducted by OWL-S are provided as an example of service descriptions. At the last section, this paper also presents the architecture of U-City management center which enables automatic service discovery, selection, composition and interoperation.

Recently applications of RFID technologies in production and logistics systems are expanding. In this research, we deal with workflow modeling methods for handling RFID-tagged parts. We verified that the material flow processes in a RFID system can be designed and assessed using workflow modeling notations, and suggested available process patterns using BPMN. In addition, we proposed an algorithm to monitor the exact status of flows and determine whether some of the events are ghost reads or not by referring predefined workflow definitions. The major contribution of this research is that it has demonstrated how well-established workflow modeling methods can be applied to RFID-based systems.

IPTV Service was launched with great expectation, but it is having difficulty due to the low number of subscribers and contents. In addition, the study of IPTV is still in its infancy and most of previous studies are only focused how IPTV is adopted and spread. In this study, we defined that resistance is the users not tend to accept IPTV service, and analyzed factors affecting resistance which are Innovative characteristics, User characteristics, Service characteristics and proposed implications for IPTV service vitalization. The results that relative advantage, complexity, attitude of an existing product, contents, cost, innovativeness have significant effects on resistance to IPTV.
