Game development costs a lot of money. Thus, in terms of cost-saving, game companies produce prototypes and undergo several tests and modifications during the development period. In this paper, we proposed a brainwave signal analysis system and linked it with the game to measure the player's emotion through brainwave analysis experiment and tried to solve these problems. The brainwave signal analysis system proposed in this paper is capable of various applications according to various development situations, such as the progress of the game, events, etc. in obtaining simple figures over time by linking games, and collecting the tester's responses according to development intentions, so there will have to be continuous additional research.

Recently, application areas based on M2M (Machine-to-Machine communications) and IoT (Internet of Things) technologies are expanding rapidly. Accordingly, water flow and water quality management improvements are being pursued by applying this technology to water and sewage facilities. Especially, water management will collect and store accurate data based on various ICT technologies, and then will expand its service range to remote meter-reading service using smart metering system. For this, the error in flow rate data transmitting should be minimized to obtain credibility on related additional service system such as real time water flow rate analysis and billing. In this study, we have identified the structural problems in transmitting process and protocol to minimize errors in flow rate data transmission and its handling process which is essential to water supply pipeline management. The result confirmed that data acquisition via communication system is better than via analogue current values and pulse, and for communication method case, applying the industrial standard protocol is better for minimizing errors during data acquisition versus applying user assigned method.

The objective of this study is to develop 3D anthropometrical data acquisition method of human back surface and to recognise and extract its morphological characteristics. This technique is very useful in describing the sitter's back contour and the interaction between the sitter's back and the seat. The back surfaces of subjects in sitting posture are measured by using martine-type anthropometer and sliding gauge. These basic anthropometrical data are reconstructed into 3D image.

Recently the construction of the ERP(Enterprise Resource Planning) system becomes accomplished actively from the many enterprises. But the many problems occur in acquisition of production data which is a fundamental data of system. Also to delay the acquisition of the production result is fatal in the efficient business operation. The construction of the POP(Point of Production) system which acquires production data at real time is become accomplished widely, In the POP system it is most important to acquire the production data which is accurate. But the many enterprises drop the competitive power with acquisition of the data which could not be trusted. In this paper, we analyze these causes and present the method which it can improve the reliability of production data. Also we introduce a real application case.

Data acquisition system mounted on the Solar Flare Telescope at Bohyunsan Optical Astronomy Observatory is briefly described. The system is made up with CCD cameras, an image processor, a PCI-type PC and a SUN workstation. The image processor, MVC 150/40 comprises a variable scan acquisition module, an image manager and a binary correlator computational module. A typical polarization image of a sunspot is presented to demonstrate performance of the system.

This paper deals with a new bit conversion method. When 12 bit AID converter is adapted to 16 bit micro-computer, complicated data aquisition method is not necessary to acquire the AID converted data into memory of computer. However, when the 12 bit AID converter is adapted to the 8 bit micro-computer 12 bit data should be divided into 4 bit data and 8 bit data. Therefore the old data-dividing method made 4 bitl2byte of memory space wasted. On the contrary, using the new bit conversion method suggested in this paper the two of 12 bit data are converted into 3 byte of data without extending the AID conversion time.

In this study, prototype DAU with LoRa wireless communication module is designed and manufactured. Also, the customized software is developed for the automatic data transmission to end-user from ThingPlug server of SK telecom LoRa network. For verification of the developed wireless monitoring system, DAU was installed on bridge construction site. The reliability of data and operational stability was evaluated by comparison with data from conventional monitoring system.

본 논문에서는 현재 건설 중인 목포대교와 선박 사이의 충돌 위험도 평가에 필요한 선박 정보와 기상 정보 수집 장치(Data Acquisition System, DAS) 개발에 관하여 기술하였다. 본 연구에서는 DAS를 통항 선박과 기상 현황 데이터를 수집하기 위한 신호 수신 및 처리 유닛과, 데이터 전송과 분배를 위한 네트워킹 유닛, 데이터 관리를 위한 유닛 등으로 구성하였다. 목포항 여객터미널과 신안군 안좌도를 왕복하는 카페리 선상에서의 현장 실험을 통해, 충돌 위기 평가에 적합한 정보를 DAS가 제공할 수 있음을 알았다. 또한 5차 버터워스 디지털 필터를 이용하여 기상 데이터에 포함된 잡음성 데이터를 충분히 억제할 수 있었다.

A microcomputer system consisting of 16-bit microcomputer, PCL-711S interface board, censors, and converters have been set up in order to automatically measure temperature, humidity and weight loss which are major variables of storage of apple. This system was operated by PC-LabDAS software. It has been possible to measure continuously the weight loss of Fuji apple stored in CA with the weight converter made by a miniature load cell and a strain amplifier. The temperature was checked by a k-type thermocouple and Pt 100 RTD, and humidity by PQ653JAl humidity sensor. It has been possible to set up a linear equation which showers high correlationship between the estimate of temperature, weight humidity and the output of the converter in that r2 is more than 0.99. Transpiration rate, a significant factor of quality deterioration for CA storage of apple, can be estimated with these values.
