In this paper, various growth environment data collecting and monitoring based on wireless sensor network for greenhouse environmental monitoring system is designed and implemented. In addition, greenhouse control system is proposed to integrated control and management in internal environment and greenhouse facilities. The system provides real-time remote greenhouse integrated management service which collects greenhouse environment information and controls greenhouse facilities based on wireless sensor network. Graphical user interface for an integrated management system is designed based on the HMI and the experimental results show that the sensor data were collected by integrated management in real-time.

This paper presents the smart system platform for remotely controlling the windows and doors system(WDS), which gathers and analyzes the state of WDS and the environmental data for preventing crimes and keeping a pleasant indoor. In particular, standard API between the smart WDS platform and the smart home platform has been presented to be easy to a home services, such as security, safety, and home appliance control. The private gateway of wire and wireless communication interfaces has been developed to remotely control and monitor the WDS for anytime and anyplace solving the crime prevention and ventilation problem. Web-and App-based user interface in order to detect the opening and shutting states and remotely control WDS have also been developed to support the mobile environment, respectively.

Android has become the most popular platform for mobile devices. However, Android still has critical performance issues, such as "application not responding" errors and hiccups resulting from garbage collection. Many phone vendors have tried to resolve the problems by characterizing and improving the performance. However, there are few insightful performance analysis tools for the Android-based systems. This paper presents AndroScope, which is a performance analysis tool for both the Android platform (Dalvik virtual machine, core libraries, Android libraries, and even Linux kernels) and its applications. To the best of our knowledge, this is the first tool to collect and analyze performance data from all the software layers of the Android-based systems. AndroScope offers a trace mechanism to collect such deep and wide performance data as hardware performance counters, time, and memory usage. In addition, the tool includes TraceBridge, which is a middleware for the fast handling of mass logs. Moreover, AndroScope offers an integrated graphical user interface with the Android software development kit to display a great volume of the detailed performance data.

Because in the amusement park, a number of people use various vehicles facilities complicated arraigned, it needs an effective way to search optimal path to reduce errors in touring a park. Particularly, when choosing a facility, searching a waiting time-based path as well as shortest path is important. This paper presents a path recommendation system which minimizes total park tour time based on tour distance and waiting time through GPS and wireless internet. This system can also recommend customized tour path based on the characteristics of user members as well as a simple shortest path.

In these days, providing flexible and personalized network services subject to customers' requirements becomes an interesting issue for network service providers. Moreover, because each network service provider own finite network resources and infrastructure, dynamic network provisioning is essential to leverage the limited network resources efficiently and effectively for supporting personalized network services. Recently, as the population of mobile devices increases, the location-awareness becomes as important as the QoS-awareness to provision a network service dynamically. In this paper, we propose a framework for providing location-aware dynamic network services. This framework includes the web user interface for obtaining customers' requirements such as locations and QoS, the network generator for mapping the requested locations and network infrastructure, the network path calculator for selecting routes to meet the requested QoS and the network controller for deploying a prepared network services into SDN(Software-Defined Networking) enabled network infrastructure.

In this paper, We design and implement a humanoid robot, With Educational purpose, which can collaborate and communicate with human. We present an affective human-robot communication system for a humanoid robot, D2, which we designed to communicate with a human through dialogue. D2 communicates with humans by understanding and expressing emotion using facial expressions, voice, gestures and posture. Interaction between a human and a robot is made possible through our affective communication framework. The framework enables a robot to catch the emotional status of the user and to respond appropriately. As a result, the robot can engage in a natural dialogue with a human. According to the aim to be interacted with a human for voice, gestures and posture, the developed Educational humanoid robot consists of upper body, two arms, wheeled mobile platform and control hardware including vision and speech capability and various control boards such as motion control boards, signal processing board proceeding several types of sensors. Using the Educational humanoid robot D2, we have presented the successful demonstrations which consist of manipulation task with two arms, tracking objects using the vision system, and communication with human by the emotional interface, the synthesized speeches, and the recognition of speech commands.

Graphical user interface(GUI) has a very important role to interact with software users. However, designing and coding of GUI are tedious and pain taking processes. In many studies, the researchers are trying to convert GUI elements or widgets to code or describe formally their structures by help of domain knowledge of stochastic methods. In this paper, we propose the GUI elements detection approach based on object detection strategy using deep neural networks(DNN). Object detection with DNN is the approach that integrates localization and classification techniques. From the experimental result, if we selected the appropriate object detection model, the results can be used for automatic code generation from the sketch or capture images. The successful GUI elements detection can describe the objects as hierarchical structures of elements and transform their information to appropriate code by object description translator that will be studied at future.

With the development of wireless Internet technology and the expansion of the game market, various forms of games are being developed that are mounted on various platforms, including mobile platforms. In this environment, ensuring the immersion of the game user's perspective will secure the game's competitiveness, so it is necessary to increase the immersion by satisfying each area presented by the Human Computer Interaction (HCI) theory. To this end, this high school implemented downhill games and experimented with kiosks by applying an interface that recognizes the human body's movements as a way to secure freedom and immersion of game users.

최근 3D 모바일 게임이 이슈가 되고 있다. 휴대폰이 필수품인 시대가 왔고 휴대폰만 있으면 어디서든 게임을 즐길 수 있다는 점 때문에 모바일 게임 산업은 급속도로 발전하고 있다. 그리고 점차 모바일 환경이 하드웨어가 발전하고 3D 가 지원되는 게임 전용폰이 나오면서 모바일 3D 게임이 많이 개발되고 있다. 그러나 휴대폰의 기본 기능은 통화하는 것이니 만큼 PC 에서의 게임이나 플레이스테이션 같은 게임기와는 구조에 차이가 있다. 모바일 환경에서는 휴대폰 버튼만을 사용하여야 한다는 제약이 있다. 그래서 현재 출시된 여거 모바일 게임의 UI 와 기존 PC 게임의 UI 를 비교하고 휴대폰이라는 제한된 환경에서의 도시경영 3D 시뮬레이션 게임을 위한 효율적인 UI 를 만들고자 하였다. 휴대폰에서는 마우스를 사용할 수 없기 때문에 기본적인 게임 조작은 전부 버튼으로 조작할 수 있게 하였다. 그리고 도시경영시뮬레이션 게임이기 때문에 일반 아케이드 게임이나 캐주얼게임에 비해 상대적으로 메뉴가 많고 복잡하다. 그래서 사용자가 설명을 바로 보면서 메뉴를 선택할 수 있도록 메뉴선택은 전부 숫자버튼을 사용하였다. 그리고 사용자가 메뉴를 외우고 있지 않아도 사용가능 하도록 화면 위에 메뉴설명이 같이 나오게 하였다. 사용자는 메뉴별 설명을 보면서 원하는 쪽으로 선택을 하게 된다. 지역설정에서는 마우스의 드래그기능이 안되기 때문에 처음시작점과 끝부분을 선택하여 마우스를 대신하였다.

In this paper, we design and develop an educational virtual system which can experience Goguryeo tomb murals in the virtual world. Goguryeo tomb murals are well known in the world, and they are registered as a UNESCO World Heritage site by the value Acknowledged worldwide. We design an user-friendly interface for Goguryeo tome murals by Flash, and make a modelling and rendering with 3D Max. In addition, we create an educational animation with Adobe Premiere. We choose some of items such as Goguryeo tomb murals, historical sites, high-level description of periodization, Goguryeo's clothes, home, play as sub-themes, and we develop a system with detailed views and informations for the daily life of the people of Goguryeo.
