Advancing information technology have rapidly changed our service environment of life, culture, and industry. Computer information communication system is applied in medical, health, distribution, and business transaction. Smart is using new information by combining ability of computer and information. Although agriculture is labor intensive industry that requires a lot of hands, agriculture is becoming knowledge-based industry today. In agriculture field, computer communication system is applied on facilities farming and machinery Agricultural. In this paper, we designed and implemented application that provides personalized agriculture related information at the actual farming field. Also, this provides farmer a system that they can directly auction or sell their produced crops. We designed and implemented a system that parsing information of each seasonal, weather condition, market price, region based, crop, and disease and insects through individual setup on ubiquitous environment using location-based sensor network and processing data.

With the increasing popularity of social network services (SNSs), there have been many attempts to analyze the users of SNSs. By doing so, the characteristics and preferences of the users can be understood, which can help companies provide personalized information and services that they need or are relevant for them. This study aimed to analyze the usage behavior of Korean Twitter users from various perspectives to deepen the understanding of it. For this research goal, an online survey was conducted for the users of Twitter and the data about their actual usage were collected using the open API of Twitter. Factor analysis of the data revealed five factors that explain about 69.3% of the usage variables. It was also investigated how the factors are related to gender, age, and brand preferences. The results showed that the usage behavior of Twitter is largely affected by age (p<0.001), and also by gender through an interaction effect (p<0.05). Also, the factors showed significant statistical correlations with the brand preferences of the users.

AUTOSAR is a partnership of automotive manufacturers and suppliers working together to develop and establish a de-facto open industry standard for automotive software architectures. In the AUTOSAR architecture, the runtime environment is at in the heart of the AUTOSAR architecture to provides the infrastructure services that enable communication between software components and between software components and basic software components. The RTE generator is an automated generation tool for AUTOSAR specification based RTE according to the ECU configuration. It generates communication API function for the software components and the basic software components like OS and COM of the application. The availability and the accuracy of the RTE generator are important for the automobile software which is based on AUTOSAR architecture, this paper proposes an architectural design of the RTE generator for auto-generation of the AUTOSAR based RTE.

This paper presents a graphic user interface system consisting of graphic simulator and remote control system for a building cleaning robot. It provides a tool of convenient 3D graphical map construction for real world. The 3D map is reconstructed from existing 2D building CAD data with DXF format by using OpenGL graphic API. Through this system, graphic display of robot's status information, remote control and cleaning scheduling can be done for a building cleaning robot. This proposed system is expected to give efficient way of graphic simulation and remote monitoring and control system for a building cleaning robot.

As the increasing national power crises due to various environmental factor, power market change is needed more developed and systemized DSM(Demand Side Management) search at DR market. To overcome national power crisis outbreaking every year and manage the eletric power reserve ratio, we need to construct and develop the electric safety manager and general public main oriented national power plant. For the advanced national power demand management system, it is required the application development like OpenAPI, Big Data Acquisition, Web/APP basd on ICT.

As of 2006. 3. the twitter offered in the USA has been one of the propaganda instrument used with ads and politics functioning speedy information diffusion on SNS communicated with others through 140 letters of short messages. and while twitter is using propaganda instrument, it keeps on trying to verify how it has an effect on. So, on the paper, I suggest new simulation model of information diffusion based on probability being able to predict the range of proliferation after it analyze the existing influence and the diffusion force on verification methods. It designed algorithm of verification and algorithm of prediction to use twitter's Open API with Python basement. It proved effectiveness on the model through the analysis to operate the twitter of practical local autonomous entity.

본 논문에서는 LBS를 이용한 지하철 이용 서비스를 제안한다. 이 서비스는 지하철 내부에서 자신의 정확한 역 내 위치를 추적하고 공유할 수 있도록 하여 이용자의 편리성을 극대화 한다. 이 서비스는 GPS와 모바일통신 기술을 기반으로 하여 지상/지하 관계없이 사용자 자신의 위치를 추적함으로서 공간의 이동에 따른 서비스제약을 최소화 한다. 단순히 현재 위치를 실시간으로 제공하는 것을 목적으로 하는 것이 아니라 추출한 위치를 기반으로 목적지까지의 보다 정확한 도착시간, 잔여시간, 남은 정거장수, 알람시간 등의 정보를 제공하여 기존 서비스에서 더욱 고급화되고 향상된 서비스를 제공한다. 본 논문에서는 google map, naver map등의 open API를 이용하여 지도상에서만 제공하는 지하철 LBS보다 응용력 및 서비스 품질 면에서 우수함을 보인다.

This paper suggests a method to expand linkages in a Linked Open Data(LOD) cloud that is a practical consequence of a semantic web. LOD cloud, contrary to the first expectation, has not been used actively because of the lack of linkages. Current method for establishing links by applying to explicit links and attaching the links to LODs have restrictions on reflecting target LODs' changes in a timely manner and maintaining them periodically. Instead of attaching them, this paper suggests that each LOD should prepare a link policy and publish it together with the LOD. The link policy specifies target LODs, predicate pairs, and similarity degrees to decide on the establishment of links. We have implemented a system that performs in-depth searching through LODs using their link policies. We have published APIs of the system to Github. Results of the experiment on the in-depth searching system with similarity degrees of 1.0 ~ 0.8 and depth level of 4 provides searching results that include 91% ~ 98% of the trustworthy links and about 170% of triples expanded.

To propagate clinical disease management service, there should be built a ecosystem where service developers, service providers, device suppliers closely cooperate for u-Health platform. However, most u-Health platform is difficult to build an effective ecosystem due to the lack of secure and effective PHR(Personal Health Record) management, the lack of personalized and intelligent service, difficulties of N-screen service. To solve these problems we suggest the CDMP(Chronic Disease Management Platform) architecture. The CDMP is a software platform that provides the core functions to develop the chronic disease management services and performs a hub function for the link and integration rbetween various services and systems. CDMP is SOA based platform that enables a provision of reusability, expansibility and it provides open API where everybody can share information, contents and services easily. CDMP supports the multi platform system foN-screen service and the self management functions via SNS. In this paper, we design and implement the CDMP including PHR service based on hybrid data model for privacy preservation. Experiment results prove the effectiveness of hybrid model-based PHR service.

Since a 'Well-being' theme had become an issue in 90's, everyone now care about their health more than ever. Besides, IT has been developed so tremendously that we have various ways to collect up-to-dated information through the internet. There are so many web sites that contain information about health and diet. However, the menus of these web sites are not simplified and the content is too large, so the information we see in those web sites may not be accurate. Also, some information is out-of-dated. In this paper, we propose a web site called 'Calory&Diet' that provides customized information on diet. The characteristics of the web site are as following: First, the menu is so simple that users can easily find information they want. Second, it only provides necessary customized information. Lastly, it uses an open application that helps users always get the latest information without DB updates. With its user friendly menu and feedback information, the proposed web site can be a good advisor for people who want to be healthy. 100 offers the user survey results than existing systems, simple system to 2%, 3% from a custom-related topics, the latest related topics were 3% higher on 5 point scale.
