As the radioactive-related incidents have been occurred frequently such as Fukushima nuclear exposure incident, it is always considered radioactivity normal levels in radiation exposure as a most risk components at several government agencies. In this paper, the data were analyzed by information in the data beyond range of the attributes. The clustering analysis method is used by EM and SimpleKMeans algorithm. The experimental results about US Radioactive associated data is depending on the method of data analysis. It can be seen that the method of the algorithm is different depending on local value of the normal range. The governments need to pay attention to increase the investigation frequency.

The purpose of this study was to investigate the quality characteristics and antioxidant activities of noodles added with red lentil powder (RLP). Noodles were prepared by addition of 0, 15, 30, and 45% powder to flour of the basic formulation. RLP noodles were evaluated for their cooking properties (weight, water absorption, volume, and turbidity), color values, texture characteristics, sensory characteristics, and antioxidant activities. The weight, water absorption, and volume of cooked RLP noodles increased according to RLP content. The turbidity values of cooking water increased according to RLP content. The L value of RLP noodles decreased with increasing amounts of RLP, whereas a and b values increased with increasing amounts of RLP. The texture characteristics of RLP noodles decreased compared to those of control noodles except for adhesiveness. Antioxidative activities of RLP noodles significantly increased with increasing RLP content (P<0.05). The sensory preference test revealed that RLP 30% noodles showed the highest scores for smell, taste, chewiness, and overall preferences. It is suggested that RLP 30% noodles could be substituted for wheat flour to improve noodle quality.

The pick & place module is used as a core module in the process equipment for producing and inspecting semiconductor components. The conventional pick & place module has the disadvantage that the precision and durability of the system are reduced and the size and weight of the module are increased by using a conversion device that converts rotary motion into linear motion. In this study, we proposed a pick & place module that implements up-and-down linear motion without a conversion device by improving such disadvantage and employs a linear motor with no limit on average thrust and travel distance. Design parameter values, that can reduce cogging force while maintaining average thrust by selecting parameters for designing a core type linear motor with a large thrust to volume ratio and analyzing the effect of cogging force according to design parameter changes through magnetic analysis, was selected. Average thrust and cogging force were measured for the pick & place module composed of the manufactured linear motor and compared with the design values.

Liquid calcium fertilizer evenly dispersed has been prepared using calcium carbonate powder and several surfactants. The calcium contents of nine fruits and vegetables were compared after spraying the liquid fertilizer onto the leaf of them six times for 2 months. The calcium contents of cabbage and potato increased to 155% and 154%, respectively. In addition, by virtue of the relatively high contents of calcium, rigidities of the texture were also increased, which would result in higher value-added vegetables. Kimchi was prepared using a Korean cabbage sprayed with the liquid calcium fertilizer and its fermentation characteristics were analyzed. A sensory evaluation has been performed to give the best result for a calcium Kimchi fermented for 14 days.

In this paper, we propose a matrix based real-time pattern matching method, called MDPI, for real-time intrusion detection on several Gbps network traffic. Particularly, in order to minimize a kind of overhead caused by buffering, reordering, and reassembling under the circumstance where the incoming packet sequence is disrupted, MDPI adopts independent partial matching in the case dealing with pattern matching matrix. Consequently, we achieved the performance improvement of the amount of 61% and 50% with respect to TCAM method efficiency through several experiments where the average length of the Snort rule set was maintained as 9 bytes, and w=4 bytes and w=8bytes were assigned, respectively, Moreover, we observed the pattern scan speed of MDPI was 10.941Gbps and the consumption of hardware resource was 5.79LC/Char in the pattern classification of MDPI. This means that MDPI provides the optimal performance compared to hardware complexity. Therefore, by decreasing the hardware cost came from the increased TCAM memory efficiency, MDPI is proven the cost effective high performance intrusion detection technique.

NDT (Non Destructive Test) of the adhesive joints is very important because their strengths have greatly affected by the worker's skill and environmental condition. Recently, the electric impedance method in which 1-2 wt% CNT was dispersed in the adhesive and the electric resistance of the adhesive joint was measured was suggested for the defect detection of the adhesive joint. The uniform dispersion of CNT in the electric impedance method is very important to make a constant electric resistance of the adhesive joint and the accuracy of defect detection depends on the uniform dispersion. In this paper, the adhesive joints in which CNT was dispersed in the adhesive by the four dispersion methods were made and their electric resistance were measured. The pre-process and evaporation process of CNT using the ultrasonic method and agitation method was used and the effective dispersion method was suggested. Also, the criteria to evaluate the dispersivity was proposed.

The objective of this study is to investigate the quality characteristics of yanggeng prepared with different amounts of Crataegi fructus extracts(CFE; 0, 5, 10, 15, 20). Increasing the amount of CFE in the yanggeng tended to increased the moisture and acidity, while it decreased the level of pH. In chromaticity determination, the values of lightness(L) and yellowness(b) showed a decrease. However, the value of redness(a) increased by increasing levels of CFE. In addition, hardness increased by increasing levels of CFE. Although regarding texture profile analysis, hardness and springiness of yanggeng were increased, adhesiveness and cohesiveness of yanggeng were decreased. Cohesiveness shown similar result compared to the control and CFE added treatments. The sensory evaluation indicated that CFE 15 showed the best preference in color, taste, texture, flavor, and overall acceptance. Based on these results, 15% should be recommended as a optimum level of CFE to be added for the preparation of yanggeng. And these results suggest that CFE may be a useful ingredient in yanggeng for improvement of the quality.

In rehabilitation where ultrasonographic diagnosis is not popular, it could be subjective by medical expert's experience. Thus, it is necessary to develop an objective automative procedure in ultrasonic image analysis. A disadvantage of existing automative analytic procedure in musculoskeletal system is to designate an incorrect muscle area when the figure of fascia is vague. In this study, we propose a new procedure to extract more accurate muscle area in abdomen ultrasonic image for that purpose. After removing unnecessary noise from input image, we apply End-in Search algorithm to enhance the contrast between fascia and muscle area. Then after extracting initial muscle area by Up-Down search, we trace the fascia area with a mask based on morphological and directional information. By this tracing of mask movements, we can emphasize the fascia area to extract more accurate muscle area in result. This new procedure is proven to be more effective than existing methods in experiment using convex ultrasound images that are used in real world rehabilitation diagnosis.
