Sensor application systems for remote monitoring and control are required, such as the establishment of databases and IoT service servers, to process data being transmitted and received through radio communication modules, controllers and gateways. This paper designs and implements database server, IoT service server, data processing middleware and IoT management system for IoT based services based on the controllers, communication modules and gateway middleware platform developed. For this, we firstly define the specification of the data packet and control code for the information classification of the sensor application system, and also design and implement the database as a separate server for data protection and efficient management. In addition, we design and implement the IoT management system so that functions such as status information verification, control and modification of operating environment information of remote sensor application systems are carried out. The implemented system can lead to efficient operation and reduced management costs of sensor application systems through site status analysis, setting operational information, and remote control and management.

우리나라는 공간정보 활용을 위해 업무별 공간정보 응용 시스템을 구축하고 있으나 정보에 대한 공유 및 활용도가 낮아 국토교통부를 중심으로 공간정보 시스템의 공동활용을 위한 체계 구축에 노력하고 있다. 본 연구는 지방자치단체에서 운영하고 있는 공간정보 응용 시스템 현황을 조사 및 분석하고, 무인항공 영상을 이용한 공간정보 응용 시스템의 공동활용 방안을 제시하고자 하였다. 연구를 통해 기존의 공간정보 응용 시스템의 기능이 대민서비스에 집중되어 있고, 행정부서 간 데이터 공유 및 활용이 어려운 실정임을 파악하였다. 또한, 공간정보 응용 시스템의 공동활용을 위해 무인항공영상 기반의 임차 및 전용면적 차이 산출, 무단 점유지 정보 확인 등 방안을 제시하였으며, 공간정보 응용 시스템 공동활용을 위한 벡터 표시, 면적계산, 보고서 생성 등 추가 기능을 도출하였다. 향후 추가적인 연구를 통해 공간정보 응용 시스템의 기능 추가가 이루어진다면 관련 분야의 현장실태조사 및 정책결정의 기초자료로 활용이 가능할 것이며, 공간정보 분야의 경험이 없는 비전문가도 정확도 높은 공간정보를 다양한 분야에 활용함으로써 업무의 효율성을 높일 수 있을 것이다.

The title of this project is "A Simple Interactive 3D Interior Design Application for Living Room - Cost Management", focusing on developing an application that enables costing and designing to be executed concurrently in interior design phases. This is because any changes made at costing phase after design phase is completed, it will potentially lead to unnecessary increase in cost and time. Therefore, the objective of this project is aimed to devise a cost management module to be included in the proposed application, allowing interior designer to make cost-based decision at the designing phase itself. This can be achieved through its proposed functions which include total cost update, budget management, cost estimator calculator and material list generation. The methodology being proposed in this project is Prototyping Development, categorized under Rapid Application Development (RAD), by starting off with planning, analysis, design and implementation phases are performed concurrently and repeatedly in a cycle to produce a prototype until the application is completed. In the end of this project, the developed prototype is expected to contribute a better solution towards cost management in interior design.

The aim of this study was to find typology of fashion-related mobile applications through exploratory investigation and to investigate differences in Korea and U.S. App stores. And then, through the qualitative evaluation about fashion mobile applications, this study proposes fashion mobile application's design and contents which can be preferred by users. By conducting keyword search in each store, 122 Korean applications and 150 US applications were analyzed. Empirical findings revealed that there were seven major types of fashion mobile applications: brand, magazine, information, SNS, game, shopping and coordination. Information type applications took up the largest portion, and SNS and game type applications showed higher ranking among customers. There were more game Apps in US and more shopping Apps in Korean stores. More free Apps were found in Korean App stores, whereas relatively more paid Apps were found in US App stores especially in game, magazine and information type applications. And as a result of usability evaluation of fashion mobile application, users prefer SNS and information category application to shopping and brand category. Also users want continuous improvement and new contents for fashion mobile application.

Intelligent applications are crucial for increasing the popularity of shared urban electric bicycles (EBs). Building an application platform architectural system that can satisfy independent user operations is critical for increasing the intelligent usage of shared EBs. Consequently, we collected online reviews of shared EB applications, conducted semantic processing and sentiment analysis, and refined the positive and negative review data for each function. The positive and negative review indices of each function were calculated using the formulae for positive and negative review indices of product functions, thereby determining the functions that need to be improved. Each function of the Shared EB application was improved according to its business process. The main contributions of this study are to build a user requirement architecture system for the Shared EB application with five dimensions and 22 functions using the Delphi method to design the user interface (UI) of this application based on user satisfaction evaluation results; to create a high-fidelity dynamic interaction prototype and compare user satisfaction before and after improving the Shared EB application functions. The testing results indicate that the changes in the UI significantly improve the user experience satisfaction of the urban Shared EB application, with the positive experience index increasing by 69.21% and the negative experience index decreasing by 75.85% overall. This information can be directly used by relevant companies to improve the functions of the Shared EB application.

최근 주요 기업들은 쇼핑 애플리케이션을 마케팅 전략으로 개발하고, 이러한 전략을 효과적으로 실행하는데 무게를 두고 있다. 이러한 애플리케이션의 특성 중 주요한 요인을 정보제공성으로 설정하고 애플리케이션 선호도가 재구매의도에 미치는 영향과 이용빈도의 조절효과에 대해 알아보고자 한다. 그 결과 쇼핑 애플리케이션의 정보제공성은 쇼핑 애플리케이션의 선호도에 영향을 미치고, 쇼핑 애플리케이션의 선호도는 재구매의도에 긍정적인 영향을 미친다. 또한 쇼핑 애플리케이션의 특성이 재구매의도에 직접 영향을 미칠 때와, 선호도를 매개로 하여 재구매의도에 미치는 영향을 비교해본 결과 선호도를 매개로 하여 미치는 영향이 더 큰 것으로 나타났다. 그리고 이용빈도의 조절 효과를 검증한 결과 이용빈도가 낮은 경우 보다 이용빈도가 높은 경우가 더 유의하다는 결과가 나타났다.

집중 호우로 인한 침수, 산사태와 같은 자연 재해는 인명, 재산 피해 뿐만 아니라 교통혼잡 및 고립과 같은 피해를 주게 된다. 도로 공간에서 운전자들은 이러한 재해정보를 인지하지 못할 시 해당 위험지역으로 진입하게 되며 그 피해는 시간이 지날수록 확산된다. 본 논문에서는 이러한 위험지역에 대한 정보를 수집하기 위하여 스마트폰 애플리케이션과 전송받은 데이터를 관리하기 위한 C/S기반의 시스템을 개발하였다. 전송받은 데이터를 이용하여 위험지역을 분석하고 분석된 위험구간정보에 대한 공간데이터베이스를 지도 서버를 이용하여 스마트 폰 애플리케이션 상에서 표출 할 수 있어 보다 효율적인 정보 제공이 이루어 질 수 있을 것이라 생각된다.

In these days companies are rapidly implementing the extended enterprise collaboration to provide enhanced management services and products based on the enterprise integration that human resources, technologies and the management process. In this corporate environment, ASP (Application Service Provider) which is the developed type of outsourcing in the area of information technology, is a good alternative for corporate information system management. ASP defines as a software leasing service which is supplied through networks instead of purchasing application software with high price. For successful implementation of ASP, it is necessary to develop the certification methodology to ensure safety and reliability of ASP. The paper provides the safe and reliable certification methodology for ASP. In order to develop it, the critical issues related to service quality and certification of ASP are identified and the systematic certification methodology of application and service provider(service environment) domains of ASP are provided. A evaluation method for the developed certification methodology is also proposed.

This study is analyzes how consumers view the market leading Virtual Wedding Application in order to contribute to the development of the wedding industry in the future. The research consists of the following steps: questionnaires with detailed items were used to develop the application, the wedding application was developed, and questionnaires were used to get consumer responses. The results are as follows: 1) paid application service providing useful information is appropriate for busy consumers. 2) Regular updates regarding wedding trend are needed. 3) Augmented reality or development of HMD based virtual experience programs should be considered as virtual experience technology on smart devices evolve. 4) Wedding consumers want all kinds of instant information to be presented in harmony, so the application should allow consumers to obtain and to purchase information at the same time. 5) The application can help consumers to share the process of total wedding coordination with others around them. 6) Since people's awareness on virtual experience is relatively low, marketing strategies such as identifying the wedding application from other applications should be used as well as promoting useful functions are important.
