As knowledge-based society comes to the fore, sharing knowledge becomes a hot issue. Among various types of knowledge, a significance of software(applications) and contents is a huge in a current society. Moreover, along with appearance of smartphone, for instance iPhone, Application Store(also known as AppStore) utilized as a common gateway for sharing software and contents, brings a big interest for many users and developers. However, prior research to understand users' behavior on AppStore has been a scant. Therefore, the main purpose of this study is to investigate the impact of key smart service environmental factors on AppStore in order to empirically explain users' psychological feelings of intention to use AppStore. Based on a well-known technology adoption model, TAM, the study incorporates three main characteristics(user, society, and service) with six constructs(Innovation, Enjoyment, Subjective Norm, Information Level, Content variety, and Cost), influencing perceived usefulness, which then affects users' intention to use AppStore. Results provide evidence that support the tested hypotheses. The implications of the findings suggest a new theoretical work for future AppStore research and offers suggestions that the researchers and practitioners of AppStore should consider regarding the development of application and contents.

With the competitive pressure and the development of information and communication technology, many organizations have introduced various kinds of enterprise-wide systems like enterprise resource planning (ERP) systems as strategic tools for the purpose of improving organizational performance. Despite their promised strategic benefits, however, their implementation has suffered from a high failure rate and difficulty in realizing the anticipated benefits. Previous studies have indicated that one of the most critical failure reasons is the lack of knowledge sharing and utilization across organizations. As a consequence, many information systems (IS) researchers have paid attention to examining the effect of absorptive capacity closely associated with knowledge sharing and transferring on IS usage performance. ERP systems implementation involves changes not only in systems but also in processes and other social dimensions, which can be related to organizational citizenship behavior (OCB) requiring appropriate communications and interactions among organizational members. A lack of communications and interactions due to a lack of OCB might lead to weak absorptive capacity and thus negatively influence knowledge sharing across organizations, because OCB facilitates a successful collaboration among functional units and positively impacts individual's attitude toward radical organizational change. With this motivation, this study has two research objectives. First, it introduces and tests a theoretical model accounting for the relationships among performance of ERP system usage, absorptive capacity, and OCB. Second, it examines a mediating role of absorptive capacity between OCB and performance of EPR system usage. Theoretical and practical implications of the study ware discussed, along with its limitations.

Environmental-friendly agriculture(EFA) has been mainly developed at many areas which have factors of natural, social cultural and economic characteristics. These rural areas can be developed into environmental-friendly space to preserve ecosystem, natural and cultural scenery, and environmental resources. The plan for developing a regional agriculture has to get central operating bodies, producers' organizations, a homogeneous district for farming, and so on. This case study is focused on development directions and situations of the EFA of Kosam area in Anseong. Kosam cooperatives is a central managing body to produce and sell rice by duck-farming method, and to develop rural area. This cooperatives is one of the leading those that have developed the regional agriculture in Korea. Kosam area is at a disadvantage of natural-geographical conditions and farming size. Kosam cooperatives has been trying to overcome these agricultural weaknesses by introducing duck-farming method. They have got many excellent results through developing EFA as a regional agriculture. Kosam area will be a good place for green tourism if they can actualize the combination model of three demand factors (natural and agricultural scenic view, natural-friendly recreation and safe food) for green tourism in the near future.

This paper is one of the types of 'sharing economy', a social economic model that borrows and shares things, spaces, and services from the development of the 4th Industrial Revolution. Through sharing of empty space and time in the city, I would like to suggest a way to reduce the closure of small business owners in order to create jobs, which is one of urban problems in the community. We also build a platform that utilizes the free time and space of buildings through space sharing, one of the types of sharing economy, and provides education programs for start-up education, promotion, marketing, and consulting by matching small business owners with building owners. Therefore, in this paper, by sharing the space and time, the landlord and the small business can share the profits of the small business by reducing the business owner's closure and the job creation plan. Coaching urban regeneration was proposed.

The purpose of this study is to overview domestic and foreign trends in the study of the landscape evaluation through new framework of landscape evaluation studies. 108 studies on the landscape evaluation are summarized and categorized into theoretical studies, verification of theories, development of evaluation methods and applications in physical planning. Major theories in the landscape evaluation came from the psycho-physics, the evolutionary theory ann the cultural-learning theory, and were verified and applied into physical planning. Early experimental researches on landscape evaluation, based on psycho-physics, were focused on relatively simple responses to landscapes. But many studies have been gradually related to the evolutionary theory and the cultural learning theory, emphasizing biological and cultural effects on landscape evaluation. Especially, Appleton's Prospect-Refuge theory' and Kaplans' 'Information Processing model' have very strong influence in landscape evaluation. Relatively there have been many application researches in Korea, which tells there have been strong needs to solve pending practical problems caused by the rapid economic and social growth for several decades. Almost of applications in physical planning are focused on physical features of landscapes, but for more comprehensive landscape evaluation, many other factors such as cognitive and sociocultural variables should be integrated into the whole evaluation system. As a result of reviewing of landscape evaluation studies, I found the overall domestic and foreign trends and the necessity of more research on the applications in physical planning. Because this study mainly focused on academic researches, for more appropriate landscape evaluation and management there should be more practical researches including various approaches.

The purpose of this study provides the theoretical model for protecting the economic and social loss from the current alternative fuel vehicle which is developed without compatibility and senseless one's own through verifying the statistical significant by method of measuring analysis. The market scale of alternative fuel vehicle depends on customer's and station's expectation about the number of potential vehicle users. It is very difficult for vehicle manufacturer to make a decision on the standard alternative fuel vehicle as it might reduce profit and market share. Accordingly, the development of alternative fuel vehicle should have manufacturer confident on the potential profit in the future. Moreover, if we decide to use the non-standard fuel after we started to use the standard fuel, it would take a huge cost comparing with starting to use the standard fuel only. As a result, once one of companies starts to provide the non-standard fuel service, it is getting more difficult to use the standard fuel going forward. Consequently, we may review the possibility of choice on the standard fuel before the vehicle manufacturer starts service with non-standard fuel.

The concept of Communities of Practice (CoPs) has been highlighted as an effective method for knowledge sharing in Knowledge Management (KM) and has been utilized strategically by many organizations. Therefore, the need to diagnose knowledge sharing activities in CoPs has increased. Previous studies of CoP strategies has generally suggested broad guidelines without diagnosing the current knowledge sharing status of individual CoPs. Furthermore, diagnosis methodologies are not connected to the strategic direction and require considerable time and effort to conduct regularly. The purpose of this paper was to develop a sustainable diagnosis framework for identifying knowledge sharing activities in virtual CoPs and to suggest strategies for CoPs-based on the proposed diagnosis framework. Finally, the proposed diagnosis framework was applied to an educational service case.

Purpose: This study is to propose a methodology for the formation of space according to the integration of structural concept and architectural concerns in the contemporary era. Beginning with researching on the theoretical fundamentals about surface-structure, it introduces several architectural examples to analyze its own structural form and spatial characteristics, and finally simulates a model for the formation of space through a real work. Method: The study is partially based on the Executive Architectural Project for 'Village of Spring' in Seocheon, which was planned in 2008 to suggest a strategic settlement layout for urban regeneration, and completed in 2012. Making architectural vocabularies permeated into surface-structure, throughout the design process of initially pursued concepts to the design development stage, we could encounter a new type of innovative space formation. It shows that the structure is one of most useful means for the realization of architectural concepts, and a design itself. Result: The expected result of the study intends to enhance the relationship between spatial formation and surface-structure, also ultimately to produce a structural system as 'space generator' to fulfill the social needs and its requirements.
