Wireless sensor networks (WSN) can be more reliable and easier to program and use with the help of sensor database management systems (SDMS). SDMS establish a user-friendly SQL-based interface to process declarative user-defined queries over sensor readings from WSN. Typical queries in SDMS are ad-hoc snapshot queries and long-running, continuous queries. In SDMSs queries are flooded to all nodes in the sensor net, and query results are sent back from nodes that have qualified results to a base station. For query flooding to all nodes, and result flooding to the base station, a lot of communication energy consuming is required. This paper suggests an efficient in-network index solution, named Distributed Information Gathering (DIG) to process range queries in a sensor net environment that can save energy by reducing query and result flooding.

The purpose of this study was to investigate the effect of oral health status on daily life of elderly women. The subjects of this study were 142 elderly women aged 60 years or older who were surveyed through questionnaires, interviews, counseling, and oral examinations. The SPSS program was used for frequency analysis, descriptive statistics and regression analysis. The results of the study showed that the number affected on daily life were 1.4 in average and the oral health condition was the highest at scaling (59.4%). When the oral status was unsatisfactory, it was found to be uncomfortable in daily life. In case of oral pain, oral status and poor removal of calculus, the number and frequency in daily life were increased. In conclusion, the oral health of elderly women can improve their daily life ability and affect the quality of life. Therefore, a systematic oral care plan is needed through the expansion of oral health promotion education for elderly women and the development of continuous preventive programs.

For an automotive surveillance radar system, fast-chirp train based FMCW (Frequency Modulated Continuous Wave) radar is a very effective method, because clutter and moving targets are easily separated in a 2D range-velocity map. However, pedestrians with low echo signals may be masked by strong clutter in actual field. To address this problem, we proposed in the previous work a clutter cancellation and moving target indication algorithm using the coherent phase method. In the present paper, we initially composed the test set-up using a 24 GHz FMCW transceiver and a real-time data logging board in order to verify this algorithm. Next, we created two indoor test environments consisting of moving human and stationary targets. It was found that pedestrians and strong clutter could be effectively separated when the proposed method is used. We also designed and implemented these algorithms in FPGA (Field Programmable Gate Array) in order to analyze the hardware and time complexities. The results demonstrated that the complexity overhead was nearly zero compared to when the typical method was used.

A manufacturing industry has secured its competitiveness through cost reduction, research for new products, development of manufacturing technology traditionally. However, many manufacturers are being required of innovative efforts for business sustainability by emergence of new technology and industry owing to fast technology development and convergence among technologies and industries. Continuous growth can not be expected with the way of simple manufacturing and sales under the 4^th industrial revolution era. Separation of service from product is getting more vague in some specific area and a service provider is often offering its own product together. Innovation destroying manufacturing value chain with servitization can only create the new value. Basic concept of servitization, paradigm change and future prospect of manufacturing industries suffering from the 4^th industrial revolution will be analyzed in this paper. Also, the strategy, application and methodology for servitization required in the convergence period will be researched.
