Since the mid-2000, so-called Web 2.0 paradigm was emerged and has been widely extended to actual Web markets with supporting Web technologies. Among Web 2.0 services, mashups with Open APIs is regarded as one of core technologies. Web mapping is also the most dominant mashup application in Open API-based applications, so that various mashups with Google Map API and other Open APIs are developing. In this paper, current technological status is explained with web GIS file formats of KML. While, a prototype is web-based GIS layer authoring system for general users, without any kinds of GIS tools and external spatial databases. This mashup application will be used web-based feature extraction for geo-spatial web for public users.

IoT (Internet of Things) is a collective term referring to application services that provide information through sensors/devices connected to the internet. The real world application of IoT is expanding fast along with growing number of sensors/devices. However, since IoT application relies on vertical combination of sensors/devices networks, information sharing within IoT services remains unresolved challenge. Consequently, IoT sensors/devices demand high construction and maintenance costs, rendering the creation of new IoT services potentially expensive. One solution is to launch an IoT open market for information sharing similar to that of App Store for smart-phones. Doing so will efficiently allow novel IoT services to emerge across various industries, because developers can purchase licenses to access IoT resources directly via an open market. Sharing IoT resource information through an open market will create an echo-system conducive for easy utilization of resources and communication between IoT service providers, resource owners, and developers. This paper proposes the new business model of IoT open market for information sharing, and the requirements for ensuring security and standardization of open markets.

Nowadays, an open-market which provides sellers and consumers a cyber place for making a transaction over the Internet has emerged as a prevalent sales channel because of convenience and relatively low price it provides. However, there are few studies about CRM strategies based on VIP consumers for an open-market even though understanding VIP consumers' behaviors in open-markets is important to increase its revenue. Therefore, we propose CRM strategies targeted on VIP customers, obtained by analyzing the transaction data of VIP customers from an open-market using data mining techniques. To that end, we first defined the VIP customers in terms of recency, frequency and monetary (RFM) values. Then, we used data mining techniques to develop a model which best classifies and identifies infiluential factors customers into VIPs or non-VIPs. We also validate each of promotion types in the aspect of effectiveness and identify association rules among the types. Then, based on the findings from these experiments, we propose strategies from the perspectives of CRM dimensions for the open-market to thrive.

본 연구는 신뢰와 불신이 동시에 상존할 수 있고, 오픈마켓과 같은 중개형 e-비즈니스 모델의 경우 중개 업체에 대한 신뢰와 판매자(입점업체)에 대한 신뢰가 서로 분리되어 접근되어야 한다는 기존 연구들로부터 착안하여, 오픈마켓에서의 신뢰와 불신이 구매의도에 미치는 영향에 대하여 연구하였다. 구체적으로 본 연구에서는 오픈마켓에서의 신뢰와 불신을 크게 중개업체와 판매자의 관점에서 구분하고, 각 단계별 신뢰와 불신이 어떻게 전이되는지, 그리고 이들의 신뢰 또는 불신의 선행요인으로는 어떤 것들이 있는지 살펴보고자 하였다. 수집된 설문데이터에 기초하여 PLS로 분석된 실증분석 결과는 다음과 같다. 첫째, 중개업체의 신뢰는 판매자의 신뢰를 매개로 하여, 구매의도에 유의미한 영향을 미치는 것으로 나타났다. 즉, 중개업체의 신뢰가 판매자의 신뢰로 전이될 수 있음을 확인하였다. 둘째, 중개업체에 대한 불신은 고객의 인지된 위험을 매개로 구매의도에 유의한 영향을 미치는 것으로 나타났다. 셋째, 구조적 보증과 인지된 웹 품질은 중개업체의 신뢰에 긍정적인 영향을 미치는 것으로 나타났다. 이러한 본 연구의 분석결과는 오픈마켓을 운영하는 중개업체가 자사의 신뢰도 제고 뿐 아니라, 불신의 수준 역시 적절히 관리할 필요가 있음을 시사하고 있다. 다만, 불신을 유발하는 선행요인이 본 연구에서 제시되지 못하였으므로, 향후 이 부분에 대한 추가연구가 필요할 것이다.

In this review, several new technologies considered when providing an open service environment in a mobile communication network are described. Recently, 3GPP developed some standards related to IoT services for opening a service platform in an SCS environment based on the OSA concept in a 3GPP LTE system. Similarly, the development of a new framework is underway to allow a plurality of services to commonly use an API environment in which a service provider or client accesses a 5G mobile communication system. Extending the existing LTE SCEF concept, the standardization of the northbound API is applied in the 5G CAPIF environment. Therefore, it is possible to construct a framework that facilitates access from outside, and takes advantage of the common management of various open service environments. An open service platform environment is expected to play an important role in transforming a network with simple connectivity services into a variety of new service markets, or into a service environment that can create added value.

In South Korea, the growth of online shopping malls that are overtaking traditional offline distributors in sales requires the latter to concentrate on developing a variety of contents amidst the ever-changing and competitive market environment. First of all, attention should be paid to information on fashion item materials. This study examined the current status of online shopping malls with a focus on their three different types-specialized malls, general malls, and open markets-and investigated consumers' hedonic shopping motives and influence on fashion materials in terms of purchasing behavior. In doing so, this study surveyed men and women in their 20s-30s residing in Seoul or its surrounding cities and used a total of 255 questionnaires for statistical analysis. The statistical software program SPSS 15.0 was used to conduct frequency analysis, factor analysis, reliability analysis, and multiple regression analysis. The study results showed that in general and specialized shopping malls, consumers granted greater reliability and importance to fashion materials when their interest in shopping or attention to fashion items/brands was high and when they wanted rare items. In open markets, the more interest consumers had in shopping and the more sensitive they were to fashion information, the more dependent they were on prices; in other words, prices were found to have a greater influence on their purchase decisions than the quality of fashion materials. The findings of this study would be useful to marketers and distributors who are trying to develop their marketing strategies based on fashion material information, according to the different types of online shopping malls.

A recent trend in innovation paradigm is the shift from closed innovation to open innovation principles. This trend is characterized by the use of purposive inflows and outflows of knowledge not only to accelerate internal innovation, but also to expand the markets for external use of innovation. However, the Not-Invented-Here (NIH), and Not-Sold-Here (NSH) or Only-Use-Here (OUH) syndromes are the most common challenges encountered in open innovation processes. Therefore, this study has the following main aims: 1) propose a research model that explains the factors that influence NIH and NSH/OUH attitudes based on motivation theory with perceived organizational fairness and commitment, 2) investigate their impacts on NIH and NSH/OUH attitudes, and 3) provide useful theoretical and practical insights. The proposed research model was empirically tested using survey data collected from information technology (IT) professionals in Korea. One of the major findings indicates that IT professionals' perceived organizational fairness has a negative effect on NIH attitudes in open innovation process. Theoretical and practical contributions of this study are also discussed.
