As mobile distribution environment is changing rapidly and competition is more intensive in businesses today, technology based self service have been changed and developed. Among the change, financial institutes and consumers are interested in mobile banking services. This study attempted to investigate the impact of service convenience value on customer satisfaction and re-usage intention, and investigated the moderate effect of technology anxiety in the relationship between service convenience value and mobile banking service usage. For this study, data were gathered from respondents who have experience using mobile banking service and analyzed by structural equation model. A convenience value affected consumer satisfaction and re-usage intention toward mobile banking service. Also, this study found that the more technology anxiety, the less re-usage intention. The results show that management and investment to improve convenience value and to reduce technology anxiety make consumers' satisfaction and re-usage intention toward mobile banking service.

Software piracy is widespread throughout the world. It has negative effects on the software industry and the intellectual property market. Despite various deterrent policies, the phenomenon has been getting severe. The current study investigated the antecedents of software piracy attitudes and intention. In order to identify factors and their relationship, a research model for illegal piracy behavior was developed and empirically examined through a path analysis using structural equation model. Also, this study employed a multiple group structural equation model to investigate differences in structural weights across PC software user group and smartphone application user group. It was revealed that perceived benefit, habit, social factor, self-efficacy had positive effect on attitude toward software piracy, whereas perceived risk had a decreasing influence on attitude. Relationships between piracy attitudes and intentions were significant as well. Furthermore, the cross validation between two groups showed the path coefficients of habit to attitude and attitude to intention were significantly different. Implications for research and practice are discussed.

Journal of the Korea society of IT services, volume 14, issue 2, 2015, Pages 33~49
DOI : 10.9716/KITS.2015.14.2.033
The purpose of this study is to analyse the effect of information application of the elderly on their lives through analysing the key papers on the topic. To achieve the aim of this study, we searched the papers from RISS, KISS, DBpia and the National Assembly Library of the Republic of Korea, using keywords such as 'the elderly and informationization,' 'the elderly and information application,' and 'mediator effect.' In the search process, we did not limited the publication year or journal types. A total of 476 papers were searched as the result of the initial search. Based on three researchers consent of selection criteria, we finally selected 19 papers and analysed the important mediator variables between the information application and the life satisfaction or happiness. Using the content analysis, we analysed the quantitative analyses (including sample characteristics and sociodemographic statistics) and qualitative analyses (including result interpretation and policy implication about the elderly information education). After in-depth analysis of the papers, we built a table organized by the independent variable and the mediator variable. With the results, several implications were discussed and contributions are also explained.

As interests in the quality of data in database systems are growing recently, analysis and improvement of data quality in databases have been an important issue. However, there has yet to be a clear agreement on how to reasonably calculate the total cost of such project. In this paper, based on real project data and budget statistics, we develop a model to estimate the cost for quality analysis and improvement project of a database. We first conduct statistical analysis to build our basic model. Throughout this analysis, we have identified factors that determine the scale of works required to conduct the project and eventually determine the cost. In addition, we have identified factors that determine the complexity of the project. These factors can adjusts the cost determined by the scale of works. Our model is verified and improved by surveys on experts. We apply our model to newly conducted projects and observe that our model estimates the cost of each project reasonably well.
Contract Awarding Process and its Reasonable Improvement for Defense Acquisition
Eo, Hajoon ; Kim, Sung-Chul ;
Journal of the Korea society of IT services, volume 14, issue 2, 2015, Pages 69~86
DOI : 10.9716/KITS.2015.14.2.069
The current contract awarding process regulated by laws and ordinances is analyzed and more reasonable processes are suggested. To this end, the principle of economic analysis is described with emphasis on the cost-effectiveness analysis, and the laws and ordinances regulating the process are thoroughly examined. The current contract awarding rule is based on the weighted sum of effectiveness score and cost score. This may not conform to the framework of economic analysis where effectiveness is supposed to be measured as an output and cost measured as an input. An improvement is attempted to the defense acquisition system and it is recognized that the economic analysis and policy consideration should be performed separately. Concept of statistical testing is introduced to see if the results of the cost effectiveness analyses show the significant difference between the alternatives. It is suggested that the contract awarding process can be improved by performing significance test followed by the aggregation of the two analyses. A minor improvement is also suggested on the application of current rules.

The IT outsourcing industry has been widespread for decades since the growth of the system integration industry stagnates and companies need to curtail expenses and improve the quality of IT services. According to previous studies on the success factors of the IT outsourcing, its transition phase is significant because of continuity of business and the handover of knowledge. Since a transition phase consists of several projects, but its goal is different from general projects, it needs special and professional management. Therefore, recent IT outsourcing business starts to introduce PMO (project management offices), of which success strongly depends on the competencies of the PMO. However, there are only few studies on which competencies of the PMO are important. In this paper, we suggest an evaluation model of transition PMO competencies derived using the repertory grid technique and the analytic hierarchy process. Additionally, we compare the differences between the views of several stakeholders on the importance of the competencies.
A Study on the Influence of Human Behaviors and Affections on the Flow of Mobile Applications
Jo, Hyeon ; Kwak, Kiho ;
Journal of the Korea society of IT services, volume 14, issue 2, 2015, Pages 111~128
DOI : 10.9716/KITS.2015.14.2.111
In this paper, we examined the effects of emotional and individual variables on flow in the usage of mobile application. We selected four relevant emotional and individual factors such as positive affect, negative affect, addiction and habituation. We also attempted to figure out the moderating role of communication in the effect of positive affect, negative affect, and addiction on the flow. For empirical analysis, we surveyed real users of mobile application and applied PLS (Partial Least Square) methodology for SEM (Structural Equation Modeling). As a result, we found that positive affect, addiction, and habituation have significant and positive impact on the flow. Furthermore, we also found that the moderating effects of communication on the relationships between positive/negative affect and communication are significant. Our findings provide important theoretical grounds for the effects of human behavior and emotion on the flow of mobile applications. Lastly, we also suggest significant managerial implications for the development mobile applications industry.
A Study on the Selection of Test Scope and the Prioritization of Test Case Based on Modification Method for Regression Testing
Jung, Woo-Jin ; Rah, Sang-Rin ; Choi, Yong-Lak ;
Journal of the Korea society of IT services, volume 14, issue 2, 2015, Pages 129~142
DOI : 10.9716/KITS.2015.14.2.129
The purpose of this study is to suggest an effective regression testing method in order to minimize the scope of test resulting from the modification of software and to prevent mismatch of test case and test objects. As a way to improve the efficiency of regression testing which uses a change-centric testing technique, the method flow is analyzed and grasped through a static analysis based on source code in order to identify modified parts. After the order of priority is set according to the results of user action log-based dynamic analysis on identified regression testing objects, test effect can be raised by adjusting the order of priority using code complexity. Quality assurance coverage can be checked using the user action log suggested in this study, and the progress of test and whether or not each function has been verified can be checked, too. In addition, by minimizing test parts and adjusting the order of test, costs and time can be saved, making it possible to conduct regression testing effectively.

Companies and governments in an era of big data have been tried to create new values with their data resources. Among many data resources, many companies especially pay attention to data which is obtained from Social Network Service (SNS) because it reveals precise opinion of customers and can be used to estimate profiles of them from their social relationships. However, it is not only hard to collect, store, and analyze the data, but system applications are also insufficient. Therefore, this study proposes a S-POS (Social POS) system which consists of three parts; Twitter Side, POS Side and TPAS (Twitter&POS Analysis System). In this system, SNS data and POS data which are collected from Twitter Side and POS Side are stored in Mongo D/B. And it provides several services with POS terminal based on analysis and matching results which are generated from TPAS. Through S-POS system, we expect to efficient and effective store and sales managements of system users. Moreover, they can provide some differentiated services such as cross-selling and personalized recommendation services.
Applying Text Mining to Identify Factors Which Affect Likes and Dislikes of Online News Comments
Kim, Jeonghun ; Song, Yeongeun ; Jin, Yunseon ; kwon, Ohbyung ;
Journal of the Korea society of IT services, volume 14, issue 2, 2015, Pages 159~176
DOI : 10.9716/KITS.2015.14.2.159
As a public medium and one of the big data sources that is accumulated informally and real time, online news comments or replies are considered a significant resource to understand mentalities of article readers. The comments are also being regarded as an important medium of WOM (Word of Mouse) about products, services or the enterprises. If the diffusing effect of the comments is referred to as the degrees of agreement and disagreement from an angle of WOM, figuring out which characteristics of the comments would influence the agreements or the disagreements to the comments in very early stage would be very worthwhile to establish a comment-based eWOM (electronic WOM) strategy. However, investigating the effects of the characteristics of the comments on eWOM effect has been rarely studied. According to this angle, this study aims to conduct an empirical analysis which understands the characteristics of comments that affect the numbers of agreement and disagreement, as eWOM performance, to particular news articles which address a specific product, service or enterprise per se. While extant literature has focused on the quantitative attributes of the comments which are collected by manually, this paper used text mining techniques to acquire the qualitative attributes of the comments in an automatic and cost effective manner.
A Study on the eWOM and Selecting Movie According to Online Media and Replies

A great number of customers, who want to watch movies usually check out online reviews before choosing what to watch a movie. The most representative online media that customers consult are portal sites and SNS (Social Network Service). Although there have been numerous studies on online eWOM (e-Word of Mouth) and the effects of online media in businesses, it remains a question that which media is best for WOM (Word of Mouth) when selecting movies. This research examines customer's intention for consulting eWOM and for watching movies according to the number and tendency of online replies. We have compared portal sites and SNS about information of movie. The study shows that a large number of positive replies can affect the intention for WOM and choosing movies. Facebook has more influence than portal sites when choosing what to watch when replies consist of large and positive comments. However, there is no difference between the two types of media when they consist of negative comments.

Service innovation is considered a new way to gain competitive advantage and enhance firm performance. However, service innovation does not always guarantee the desired outcome. The effective organization and management of well-planned service innovation practices, which are consistent with the firm's business environment, become a critical challenge for service innovation success. In addition, an increasing number of studies have focused on the role of information technology (IT) capability in service innovations. Most studies on service innovation have focused on the influences of the strategic alignment and IT capability separately. In contrast, the current study combines them by investigating the positive moderating effect of IT capability on the alignment between business strategy and service innovation strategy. Based on data collected from 183 service firms in Korea, we first explore the effect of service innovation strategies when coupled with different business strategies on better firm performance. We then investigate the moderating effect of IT capability on the relationship between strategic alignments and firm performance. Empirical evidence indicates that a synergistic effect between alignment and IT capability on firm performance exists. Firms that have aligned service innovation strategy with business strategy should consider improving their organizational IT capability to ensure substantial leverage.

User Experience (UX) and Experience Innovation have been emphasized in the process of New Product Development (NPD). However, previous works which were conducted within the theme of UX mostly focused on the fragmentary aspects of user's experience in a specific usage-context only. For this reason, it is always hard to deal with questions on how to define the abstract concept of UX and how to apply this important keyword in actually NPD process both for satisfying potential users and for setting a market strategy. To address this issue, we focused on the fact that UX has an aspect of composition like pattern and structure. It means that we can understand the context of UX with clarifying characteristics of relations between user and experiential objects. Also, we referred to two sub-concepts of Complexity, Density and Centrality, as representative characteristics of relations in usage-context. Based on this theoretical background, we attempted to find UX design principles and concepts for NPD from the actual example cases of products and services in the real market. From these whole study process, we expect that our findings could have implications for academic and practical areas within the theme of Human-Centered Innovation.

Cloud computing is provided on demand service via the internet, allowing users to pay for the service they actually use. Categorized as one kind of cloud computing, SaaS is computing resource and software sharing model with can be accessed via the internet. Based on virtualization technology, SaaS is expected to improve the efficiency and quality of the IT service level and performance in company. Therefore this research limited cloud services to SaaS especially focused on collaborative application service, and attempts to identify the factors which impact the performance of collaboration and intention to use. This study adopts technological factors of cloud SaaS services and factors of task characteristics to explore the determinants of collaborative performance and intention to use. An experimental study using student subjects with Google Apps provided empirical validation for our proposed model. Based on 337 data collected from respondents, the major findings are following. First, the characteristics of cloud computing services such as collaboration support, service reliability, and ease of use have positive effects on perceived usefulness of collaborative application while accessability, service reliability, and ease to use have positive effects on intention to use. Second, task interdependence has a positive effects on collaborative performance while task ambiguity factor has not. Third, perceived usefulness of collaborative application have positive effects on intention to use.

Information technology (IT) convergence have been recognized one of the key drivers in the industry perspective. Especially, IT convergence have been one of the most important innovative way for defense sector. Korea government established IT convergence policy in 2008 and have been applying it to the core industry such as automotive, shipbuilding and defense industries. Recently, the creative vitamin project has been launched. Vitamin 'D' means the way to create the value of defense industry. This research analyzes and evaluates various IT convergence business models based on an operation of defense IT convergence center from 2011 to 2014, which is the industry IT convergence centers. Defense IT convergence business models can be classified into four types of mission area as follows : weapon acquisition and management, military intelligence, military power construction, and resources management. We define the concept of defense IT convergence and describe the framework and processes for applying IT to the defense sector. We analyzes and evaluates various business models designed through defense IT convergence framework and processes.

Recently, Most of the companies and government offices are under consideration about the adoption of cloud office service to actualize the smart work policies. Comparing with traditional office software, a cloud office service have the advantage of the method of payment and coming over the physical limitations. Many cloud office service users tend to adopt an official evaluated the service without doubt. However after deciding to adopt cloud office service, many users are faced with a variety of problems and difficulties practically. In this study, researchers carried out interview about those problems and difficulties after adopting a cloud office service. Consequently, there are several problems and difficulties such as compatibility, document security, document lost and maladjusted to the new graphic user interface between traditional office software and a cloud office service. A cloud office service have still several advantages not only a competitive price but also ubiquitous attributes. Thus, researchers need to study about what kinds of reason variables can solve those problems and difficulties. In existing research, DeLone & McLean have suggested information system success model. They use three independent variables which are system quality, information quality, service quality. Parameters are user satisfaction, intention to use and use. Lastly, dependent variables are net benefits. However in this study, we need to change the scope of measurement. In other words, we have to replace parameters with dependent variables. Simply, user satisfaction, intention to use and use is going to be dependent variables. There are several reasons why we need changing variables. First, we aim at giving a some suggestions to a cloud service providers which independent variables do not work to satisfy for the users. Second, we need to find out how to maximize cloud office service user's satisfaction and intention to use. Third, we should firstly know that relationship between independent variables and dependent variables. Finally, those research results give for the cloud office service provider to solve the cloud office service adopting problems and difficulties.
Knowledge Sharing in the New World of Work : Effects of the New Way of Working

The New Way of Working (NWOW) is changing the world in which we work today. The principles of NWOW are based on freedom of time and place to work, and steering on output (results) instead of input (presence). As NWOW is a relatively new phenomenon, research on the effect of NWOW on knowledge sharing in organizations is scarce. In this research two multiple-case studies were performed to investigate the effect of the New Way of Working on knowledge. In the first study (A) different knowledge sharing scenarios were used at organizations that were in the process of implementing NWOW. This provided the opportunity to compare the sharing of knowledge between 'NWOW workers' and employees that still worked in the traditional way (non-NWOW workers). In total 216 scenario results were evaluated to determine differences in channel choice between the traditional and new work environment. For the second study (B) a Knowledge Sharing Framework was developed, based on the theories of Nonaka and Alavi & Leidner. This framework was used to determine the type of knowledge shared, e.g. tacit or explicit knowledge, in 84 situations. Additionally, to measure the level of NWOW adoption, a NWOW Analysis Monitor was used. The results show that NWOW workers use more different communication channels than traditional workers. When knowledge workers become more mobile, they will exchange knowledge less explicit (codified) and more tacit (personalized), use less face-to-face communication, but more video calls and e-mail. The adoption of the principles of NWOW seems to have a balancing effect on the knowledge that is shared in a tacit and explicit way, which in the view of Scheepers et al. is an effective knowledge sharing strategy. The research results show organizations need to realize that the New World of Working is affecting the way knowledge is shared. Missing out on this development may result in the loss of important knowledge and impact the operation of organizations.

In a day and age when contemporary businesses are transformed, driven by a service-dominance logic and dependent upon IT, we need to understand how firms cope with technological adaptations and how such technological adaptations can lead to service adaptations. Drawing on a framework on technological transitions and an interpretive longitudinal case study of the services provided by a team within a large public IT firm, this article addresses the following questions : How do service transitions come about? Can we distinguish particular patterns in service transition processes? This research unveils how technological and social dimensions mutually constitute each other within development and implementation of service provisioning. The findings show how：(a) IT plays a fundamental role in service provisioning; (b) technological transitions are the necessary but insufficient preconditions for service transitions; and (c) there are attenuation effects when it comes to the move from technology transition to service transition.

Social networking services (SNSs) serve to strengthen people's social relationships by providing ways for people to utilize such relationships especially like workplace. With the development of the internet worldwide, the number of SNS users is rapidly growing and a wider range of service types have become available. In this study, we designed a research model with a focus on what makes people use SNSs at workplace and how it is associated with changes in relationship quality and their intention to continue using the services and analyzed data collected for the research model. Theoretically, intrinsic and extrinsic motivation was invoked and measured, in terms of hedonic and utilitarian values, and satisfaction and trust were adopted as variables of relationship quality. Data were collected from Facebook users using workplace, and a partial least squares (PLS) analysis was made on 188 data points. The analysis results showed that two forms of motivation-hedonic and utilitarian-are separated from each other in their influence and that utilitarian value is more important than hedonic value, especially when it comes to users' satisfaction. In addition, the analysis found a weak relationship between satisfaction and trust in SNS environments; this was a little different from the results of previous studies.
