In this paper, we propose a mechanical contact inner tap inspection system that can inspect the defect of the inner tap immediately after inner tap is processed within the machining center. The inspection module has the collet chuck structure, so it can mounted on the main spindle of the machining center during inspection. It was developed with a focus on inspection for tap having 20 mm depth which is primarily fabricated in automotive parts and has a double sided PCB-type control system including sensing function based on Zigbee module, micom and IR sensor for wireless transmission of measured data with low power operation, and also a battery for supplying electric power. The current consumption is 46.8mA in the inspection operation mode and 0.0268mA in the power saving mode for 3.7V of the applied power source, so that 30,000 times or more inspection can be performed with assumed 5 seconds inspection time for one tap. Experiments in test jig system and actual machining center confirm that the proposed inner tap inspection system can be applied to the batch process of simultaneous inspection after tapping in the machining center.

The classification of the tablets recovered according to prescription changes is usually carried out manually by a number of pharmacists at the hospitals. Relatively high-wage pharmacists carry out the reclassification of the tablets, which results in a large loss of time and labor, and if the tablets are incorrectly classified, this can lead to medical accidents. In order to overcome these problems, a new automatic tablet classifying machine has been introduced. In the conventional automatic tablet classifying machine, tablets having various shapes, sizes, and colors are transferred to a classifying machine through the line feeder. Problems such as breakaway of the tablets from the line feeder, pilling of the tablets in the line feeder, and appearance contamination of the tablets occur. In this paper, we propose a system that automatically classifies the shape, size, and color of tablets through individual supply method by vacuum adsorption and image processing.

Since sensor networks consist of sensor nodes with limited energy resources, so efficient energy use of sensor nodes is very important in the design of sensor networks. Sensor nodes consume a lot of energy for data transmission. Clustering technique is used to efficiently use energy in data transmission. Recently, mobile sink techniques have been proposed to reduce the energy load concentrated on the cluster header near a sink node. The CMS(Cluster-based Mobile sink) technique minimizes the generation of control messages by creating a data transmission path while creating clusters, and supports the inter-cluster one-hop transmission. But, there is a case where there is no connectivity between neighbor clusters, it causes a problem of having a long hop data transmission path regardless of local distance. In this paper, we propose a SCBC(Strong connection balancing cluster) to support the path of the minimum number of hops. The proposed scheme minimizes the number of hops in the data transmission path and supports efficient use of energy in the cluster header. This also minimizes a number of hops in data transmission paths even when the sink moves and establishes a new path, and it supports the effect of extending the life cycle of the entire sensor network.

In order to broaden the indication of middle ear implant, research has been actively conducted on the reverse output method that stimulates the round window. However, it is very difficult to transmit the vibration output effectively because the indivisual anatomical difference of the round window niche is very large and also the visual field is not secured even by a skilled otolaryngologic surgeon. In this paper, we propose a new reverse stimulation method of middle ear implants that transmits energy to the inner ear by using air as a medium. This can compensate for the disadvantages of the conventional method of transmitting vibration energy and minimizes the energy transfer efficiency interference due to the combination of the excitation point and the output device. It was shown that forward and backward transfer characteristics were obtained by cadaveric experiments, and it was shown that it can overcome the acoustical impedance of high round window and transmit energy to inner ear. The receiver, which is the output device of the conventional hearing aids, can generate a constant volume velocity, so it can have a high output at a limited volume, such as a round window niche. So, suggested method can overcome the high acoustical impedance of the round window and deliver acoustic energy to the inner ear.

(Most companies that perform BPR have not achieved satisfactory results or have not performed successful BPRs. There are many reasons for this, but the most important one has caused problems that do not accurately reflect the requirements of various stakeholders. In this paper, we will apply the BPR consulting methodology to a new value innovation requirements engineering process based on the Blue Ocean strategy, which is a way to create a new market without competition by customerizing potential customers by satisfying new customer expectations and needs. This paper uses a requirements engineering process that can generate customer value by applying the ERRC(Erasure Reduce Raise Create) analysis method, which is the core of the Blue Ocean Strategy Framework[1,2]. We will also apply the Six Sigma DFSS (Design For Six Sigma) methodology to improve quality and process through quantitative and systematic analysis. The proposed approach was presented to the BPR consulting to present a practical case, and the results of the empirical analysis of the system user to validate the results of BPR consulting.

When the new ammunition is designed, it is necessary to confirm in advance how long the target distance is depends on the shape and weight of the designed ammunition. Therefore we can use commercial software such as PRODAS to predict the target distance in the design stage. This commercial software has aerodynamic data for various ammunition shape and calculates the target range by calculating the kinetic equations of the ammunition using the aerodynamic data most similar to the designed ammunition. The ammunition for predicting the target distance through software such as PRODAS is a non-guided ammunition that has no control after launch but the glide type ammunition is guided and control ammunition. So it is predicts the state of ammunition after the launch. A new type of simulator is needed to analyze the maximum range and to verify the onboard guided and control algorithm. The simulator constructed in this paper is an optimized simulator for glide type ammunition. Unlike unmanned aircraft and guided missiles. The rotation characteristics of the ammunition are considered and the navigation initialization algorithm is applied. The constructed simulator confirmed the performance by performing maximum range analysis of glide type ammunition.

Intravenous(IV) therapy being in use for many patients may cause serious side effects such as infiltration, extravasation. To minimize such side effects, it is important to detect symptoms appearing when fluid escapes from blood vessel to tissue as soon as possible. This paper describes a device which has been developed to detect IV infiltration early using optical sensor. The device detects IV infiltration as measuring intensity of lights reflected from that lights after emitting lights in IV therapy site. The lights are consisted of 4 different waves which provide different reflection ratio depending the fluid used in IV therapy. The experimental results show that the device can be used to detect IV infiltration early.

This study investigates the merits of incorporating augmented reality in mobile games and proposes a mobile game application that combines augmented reality technology with gaming. The proposed study postulates that augmented reality technology can be employed for developing games on smartphones. The proposed application involves the implementation of a 3D virtual object in the real world by incorporating a target image. The proposed application also employs an intuitive interface with simplified manipulation based on touch, and allows players to collect and combine items for acquiring new items, thus making it elementary to pass the game stages. Furthermore, a ranking system has been introduced in the proposed application for enhancing the amusement factor of the game. The novelty of the proposed application lies in the fact that the virtual button function has been employed for combining physical and virtual objects while playing the game, without incorporating location-based services.

Indicators to quantitatively assess the physical conditions can help optimize the effectiveness of rehabilitation therapy for stroke patients. The body composition variations in the paretic and non-paretic regions of stroke patients with cerebral infarction (7 males, 31 females) were analyzed using multi-frequency bioelectrical impedance. Specifically, resistance (R), lean mass (LM), fat mass (FM), extracellular water (ECW), intracellular water (ICW), R/LM relation, basal metabolic rate (BMR)/LM relation were utilized to evaluate the paretic and non-paretic regions of subjects with cerebral infarction. These values showed significant differences in gender and paretic/non-paretic regions. R and FM were high but LM and ICW were lower in female and paralysis. ECW was lower in females than males, but there was no considerable difference between paralysis and non-paralysis in both males and females. In addition, there was an inverse distribution between R and LM in paretic and non-paretic regions, with males on the upper left and females on the lower right. Furthermore, the relationship between BMR and LM showed excellent linearity (slope: 22.17 kcal/day/kg) irrespective of gender, paralysis, and non-paralysis. An easy, non-invasive and quantitative assessment using bioelectrical impedance would provide an useful tool for evaluating patients with cerebral infarction receiving rehabilitation therapy.
