Due to the recent increase in the mobile streaming market, mobile traffic is increasing exponentially. IMT-2020, named as the next generation mobile communication standard by ITU, is called the 5th generation mobile communication (5G), and is a technology that satisfies the data traffic capacity, low latency, high energy efficiency, and economic efficiency compared to the existing LTE (Long Term Evolution) system. 5G implements this technology by utilizing a high frequency band, but there is a problem of path loss due to the use of a high frequency band, which is greatly affected by system performance. In this paper, small cell technology was presented as a solution to the high frequency utilization of 5G mobile communication system, and furthermore, the system performance was improved by applying machine learning technology to macro communication and small cell communication method decision. It was found that the system performance was improved due to the technical application and the application of machine learning techniques.

Since two-way interactive broadcasting service began, remote controls have been fitted with 4 color buttons, which enables interaction and convenience to increase between users and content. Currently, diverse studies on IPTV are in progress. Particularly, as the mobile market rapidly grows, studies on mobile IPTV and on linkage with other media are constantly increasing. However, mobile IPTV has never been studied until now. In that sense, this present study attempted to design a mobile-based IPTV UI that could use a multi-dimensional search method based on consistent criteria for content search. As a result, the proposed IPTV UI is fitted with more usability and functionality for 4 color buttons. The UI designed in this study was compared to the IMDb Android Application, which uses GOMS-KLM. The results showed that the performance process was reduced by three stages, and that the performance time was reduced by more than 17.9%. Therefore, the conclusion can be reached that the proposed UI is effective for a fast search of contents.

This study analyzed cases that applied hologram technology in the fashion industry in order to provide basic information for research on fashion marketing using hologram technology. The results of this study are as follows. A hologram was applied to fashion businesses in various ways including fashion shows, outdoor signboards, hologram windows or screens in stores, and launching shows or exhibitions. Most of these cases were foreign fashion brands, which utilized hologram technology actively for formulating a new brand image or for advertising products. Among Korean brands, however, there are not many cases of hologram application. Today, as-being the age of smart devices, the mobile advertisement market is growing rapidly among smart phone users. DKNY and Puma are providing information on styling through smart phone applications, and the Adidas stores in Germany also allow the customers to buy goods by entering a simple code through the smart phone. Recently, new devices are being introduced one by one, which display 2D digital contents in 3D holograms by combining mobile and hologram technologies. The marketing of fashion products is not just for supplying products but is required to satisfy the consumers' five senses. Therefore, the development of experiential contents based on the combination of mobile and hologram technologies will open new potential for profitable business models.

모바일 앱 시장은 스마트폰의 등장으로 폭발적으로 성장하였다. 최근 모바일 앱은 단순한 스마트폰 구성요소가 아니라 다양한 마케팅 채널로 활용되고 있으며 스타트업이 성장할 수 있는 발판이 되었다. 본 연구에서는 모바일 앱이 시장에 미치는 영향에 대해서 연구하고자 하였다. 안내원과의 전화를 통해서 소비자에게 서비스를 제공하던 전통적인 콜택시 산업이 카카오택시라는 새로운 모바일 앱 채널의 진입을 통해서 어떠한 영향을 받고 있는지 살펴보고자 한다. 최근 자가용과 대중교통의 발전으로 택시 수요는 감소한 반면, 개인택시 증가 등으로 택시 공급은 증가하고 있다. 택시산업은 크게 일반택시와 콜택시로 나누어진다. 일반택시는 택시기사가 직접 고객을 찾아다니기 때문에 우연적이고 비효율적인 행태를 보인다. 하지만 콜택시는 고객이 사용의도를 가지고 택시를 찾는다는 점에서 더 효율적인 업무가 가능하다. 이러한 장점에도 불구하고 콜택시 시장은 불완전한 고객-택시기사 매칭 시스템과 택시기사 관리 부족으로 크게 성장하지 못하였다. DID(differences in differences)는 하나의 시간 흐름에서 발생한 특정한 사건이 유의한 영향력을 행사하는가를 밝히는 계량경제학의 연구 방법이다. 본 연구에서는 DID를 사용하여 최근 큰 이슈와 함께 출시 된 다음의 카카오택시 어플리케이션이 기존의 콜택시 사업에 미치는 영향력을 밝히고자 하였다. 거기서 더 나아가 비윤리적인 행태로 여겨지는 대기업의 문어발식 산업 확장이 해당 시장에 어떠한 영향을 미치는지 알아보고자 하였다. 이를 위해 카카오택시 전후 콜택시 산업의 크기 비교를 통해서 콜택시 시장 변화를 확인하였다. 본 연구를 위해 2014년 8월부터 2015년 7월까지 1년치의 콜택시 수요 데이터를 수집하였으며 control group으로 사용한 대리운전 수요 데이터도 같은 기간 동안 수집하였다.

Along with the evolution of wireless internet environment, information services in mobile internet are being explosively increased. However, due to the high expense for the use of those services, it is not easy to collect the devoted customers. In order to overcome the adverse conditions, the service should be supported by a strategic application system which facilitates easier and fast service for customer's information needs than that of traditional on-line internet. In this paper, we investigate the strategy how to provide the information service under the customer satisfaction, and also consider some ways of personalization of information service and information provision in real-time. As a result of the works, we develop a system, MoSA-CRM(Mobile Service Application based on CRM) to support customer-oriented information service. We believe that the MoSA-CRM system can provide some benefits for information providers in mobile e-commerce market such as flexibility in business strategy, systematic customer relationship management, and growth in financial ability.

Purpose - The purpose of this study was to propose a win-win development plan for not only suppliers of delivery applications but also traditional market vendor companies and delivery riders by analyzing existing delivery models and presenting a new delivery model to enhance competitiveness of the traditional market using delivery apps. Research desgin, data, and methodology - Specifically, small retailers, such as traditional markets and supermarkets, presented a compromised delivery model that utilizes the platform of specialized delivery app service providers for order reception, and that the delivery is delivered by delivery systems jointly hired by Vendor companies, such as franchising companies. To validate the significance of the trade-off delivery model, a cost-benefit analysis was conducted by those involved in the delivery application. Results - From the perspective of suppliers of specialized delivery applications, it is analyzed that the use of specialized delivery applications in traditional markets will be a new market opportunity for service providers to achieve increased sales. It is expected that consumer choice and satisfaction will be increased as convenience and accessibility of traditional market businesses that were available only through direct visit from the user side of the delivery application will be expanded. From the standpoint of delivery application franchises, it is analyzed that they can seek to increase sales and increase customer service as well as ease labor cost burden due to joint employment of delivery riders. The delivery rider will be able to seek to improve customer service due to job security, wage stability, risk reduction and overheated competition due to direct employment. Conclusion - In conclusion, the compromised delivery model solved the problems raised in the preceding study conducted on delivery application suppliers, users, franchises, and riders to establish that it could be a strategic alternative to increasing sales and expanding detailed rights for the self-employed in the traditional market, which are experiencing difficulties in management. However, the adoption of a compromise delivery model requires social consensus from those involved in the delivery application and requires legal, institutional and policy support, which will require continued follow-up research on the delivery model in the future.

This study aimed to examine the current status of mobile applications for garden design and extract valuable contents for the development of garden design programs for future reference. Mobile applications released in Korean or English on Google Play App Market as of July, 2018 were analyzed in this study (1 application in Korea and 14 applications overseas). The purposes of this study are to analyze the components of the programs for those who actually intend to create a garden and to use it as a resource for developing mobile applications for garden design. Thus, program components and contents were analyzed for garden design applications based on real space (1 application in Korea and 3 applications overseas) that could actually help users. The analysis of mobile applications for garden design shows that while overseas garden programs are rapidly developing in various fields, the number of garden design mobile applications developed in Korea and the amount of information platforms are significantly insufficient. This study suggested flowchart for garden design mobile applications based on the analysis results of existing garden design application. This flowchart includes a series of processes from planning/designing gardens to purchasing plants and facilities to constructing/maintaining gardens for users who intend to design and create a real garden. Furthermore, this study proposed a freemium business model based on 4R(Reflex, Reality, Real place, Real communication) marketing strategies for mobile applications. Realistic experiences can be increased through graphics and information about gardens and plants provided in this study, and location-based information services as well as the creation of systems connected with vendors and suppliers of products related to gardens can induce consumers' purchasing behaviors. Additionally PR activities through various garden-related cultural events are expected to attract more users.
