Inorganic pigments have high thermal stability and chemical resistance at high temperature. For these reasons, they are used in clay, paints, plastic, polymers, colored glass and ceramics. CoAl2O4 nano-powder was synthesized by reverse-micelle processing the mixed precursor(consisting of Co(NO3)2 and Al(NO3)3). The CoAl2O4 was prepared by mixing an aqueous solution at a Co:Al molar ratio of 1:2. The average particle size, and the particle-size distribution, of the powders synthesized by heat treatment (at 900; 1,000; 1,100; and 1,200˚C for 2h) were in the range of 10-20 nm and narrow, respectively. The average size of the synthesized nano-particles increased with increasing water-to-surfactant molar ratio. The synthesized CoAl2O4 powders were characterized by X-ray diffraction analysis(XRD), field-emission scanning electron microscopy(FE-SEM) and color spectrophotometry. The intensity of X-ray diffraction of the synthesized CoAl2O4 powder, increased with increasing heating temperature. As the heating temperature increased, crystal-size of the synthesized powder particles increased. As the R-value(water/surfactant) and heating temperature increased, the color of the inorganic pigments changed from dark blue-green to cerulean blue.

Advertising signaling theory predicts that the amount that a company invests in advertising impacts on consumers’ perception about the quality of a product (Anand & Shachar, 2009). For this signaling to occur, some specific conditions are necessary, for example, the product must be a repetitive purchasing product and its quality must not be observable at the time of purchase, but only during the consumption of the product (Kirmani & Rao, 2000). Advertising signaling is based on the assumption of a rational consumer, who is expected to perform an objective and deliberate evaluation of the advertising actions, taking into account the amount invested by the company in the advertisement production and media and the level of investments applied by competitors in the same market to perceive the quality signals. However, this strictly rational perspective has been questioned since Simon (1947, 1955) demonstrated that humans’ rationality is limited by several factors, such as cognitive resources and selective memory, which may influence judgments and decision making. More recently, researchers have argued that affect is also a source of bounded rationality, playing an important role in the way people think and make decisions (e.g., Hanoch, 2002; Kaufman, 1999; Muramatsu & Hanoch, 2005). The objective of the present research is to examine advertising signaling theory through the consumer information processing perspective, exploring the influence of the following three variables on these processes: the individual’s mood, the level of information asymmetry about the product’s attributes and the individual’s gender. The study was applied to 390 undergraduate students in France. Three factors were manipulated in the study: the advertising investment, which was manipulated in three levels (below, the average and above the market average advertising investments for similar campaigns), the subject’s mood (two levels, positive and negative) and the level of information asymmetry about the product’s attributes (two levels, high information asymmetry and low information asymmetry). Thus, the research had a 3 x 2 x 2 experimental design. Respondents were asked to declare their gender, which was considered in a subsequent analysis. Students were approached in the university and invited to participate in the study. Twelve booklet models (each booklet contained the activities and scales related to one experimental group) were randomly distributed among the respondents who accepted to participate of the study. The results of an ANOVA analysis showed main effects of mood (F (1, 376) = 13.31, p < .001), level of information asymmetry (F (1, 376) = 135.00, p < .001) and advertising investment (F (2, 376) = 31.06, p< .001) on the respondents’ quality perception. These main effects were obtained in a context of two significant interactions, between the advertising investment and mood (F (2, 376) = 3.68, p < .050) and mood and information asymmetry about the product (F (1, 376) = 19.05, p < .001). Regarding the first significant interaction, the results showed that subjects who were informed that the advertising investment was below the market average showed similar means of product evaluation whether they were in a positive (M = 5.47) or negative (M = 5.46) mood (F (1, 364) = .000, p > .10). Those who were informed that the advertising investment was at the market average evaluated the product as significantly better when in a positive (M = 6.40) than a negative (M = 5.91) mood (F (1, 364) = 6.29, p < .05). In the same way, respondents who were informed that the advertising investment was above the market level evaluated the product as significantly better when they were in a positive (MPA = 6.94) than a negative (MNA = 6.19) mood (F (1, 364) = 14.32, p < .001). The interaction between the individual’s mood and the level of information asymmetry about the product demonstrated that subjects who were exposed to a slight level of information asymmetry, receiving some information about the product’s attributes, showed similar means of product evaluation whether they were in a positive (M = 6.71) or a negative (M = 6.74) mood (F (1, 364) = .04, p > .10). By contrast, those who were not given any information about the product characteristics, being exposed to a severe level of information asymmetry, evaluated the product as significantly better when in a positive (M = 5.83) than a negative (M = 4.96) mood (F (1, 364) = 27.63, p < .001). A second ANOVA model was conducted to examine the influence of the advertising investment and the individual’s gender on the perceived product quality. The results showed main effects of the advertising investment (F (2, 376) = 31.56, p < .001) and gender (F (1, 376) = 9.77, p < .005) on the subjects’ quality perception. These main effects were qualified by a significant interaction between the advertising investment and the subjects’ gender (F (2, 376) = 5.28, p < .010). Women evaluated the product quality as better (MW = 5.81) than men (MM = 4.71) in the context of advertising investments below the market average (F (1, 370) = 19.05, p < .001). This difference disappeared in the contexts of advertising investment at the market average (MW = 6.19, MM = 6.14, F (1, 370) = .04, p > .10) and above the market average (MW = 6.70, MM = 6.52, F (1, 370) = .55, p > .10), in which men and women showed similar means of perceived product quality. The results show that positive mood influences in the individuals’ perceived product quality specifically in situations of advertising investment at the market average and above the market average. When individuals were informed that a level of advertising below the market average was invested, they demonstrated similar means of product evaluation irrespective of their mood. By contrast, in situations in which they were informed that the company invested approximately the same as competitors in similar advertising campaigns, or even above this amount, respondents who were in a positive mood evaluated the product as significantly better than those who were in a negative mood. The fact that the advertising investment interacts with the individual’s mood suggests that both variables are likely processed by the same information processing route, namely, the peripheral route (Elaboration Likelihood Model, Petty, Cacioppo and Schumann, 1983). That is, although individuals are expected to compute the information related to the advertising investment through the central route, the signal emitted through the advertising investment is more likely processed by the peripheral route. Thus, this signal is also a heuristic element on which individuals based their product evaluations. Our findings also demonstrate gender differences in the processing of the information signaled through the advertising investment only in situations of advertising investment below the market average. In the contexts in which the advertising investment was manipulated below the market average, women evaluated the product as better than men. Nevertheless, in situations in which the advertising investments were manipulated at the market average and above the market average, men and women showed similar levels of perceived product quality. An explanation for this effect is that women are better able than men to process the information sent through the advertising investment and, thus, to perceive the advertising signal only at a specific level of advertising investment. Above a certain level of advertising investment, men are as motivated as women to process this information, causing the gender differences to disappear. This finding is consistent with the Selectivity Model (Meyers-Levy, 1989), which predicts that some situational elements may stimulate men and women to engage in an effortful and detailed processing of the information that can eliminate the differences between the genders. Thus, in situations in which the investment in advertising is sufficient to encourage both women and men to process it, the genders become equally sensitive to the advertising signaling.

This study investigated the relative contributions of linguistic knowledge and strategy use to L2 listening success, especially in bottom-up and top-down dominant listening tasks. Participants (n = 130) were Korean college students in a required listening course. The tested variables for linguistic knowledge were sentence processing speed, grammar, receptive vocabulary, and productive vocabulary. Listening strategy use was measured with a metacognitive awareness listening questionnaire. We hypothesized that linguistic knowledge will make greater contributions to Bottom-Up-Listening-Comprehension (BULC) than to Top-Down-Listening Comprehension (TDLC), and different aspects of strategies will be accessed in each comprehension type due to different psycholinguistic features of the tasks. A series of stepwise multiple regressions were conducted and confirmed our prediction. The unique variance explained by linguistic knowledge was 27.8% in BULC, but 22.4% in TDLC. Strategy items that address problem solving and mental translation were significantly related to BULC, while items dealing with directed attention and person knowledge had significant explanatory power for TDLC.

Non-slip friction coefficient of the burner after processing was measured to obtain a mean value of 53.2 BPN. Production rate for stone items was measured by the time of the burner and the result passed through the brush was 26.94 m/s on average.

In this article, to predict the wear amount of nano particles in a worn nano composite, computational analysis pre/post-processor were developed using ABAQUS and visual basic programs. The abrasion, which is one of nano particles release scenarios, was applied in the computational analysis. Moreover, reciprocation, which is the abrasion type, was selected and incarnated in abrasion computational analysis. Also, to predict wear amount of nano composite in computational analysis, archard equation was applied and the predicted wear amount was evaluated compare with experimental value. The predicted wear amount of nano composite was increased in accordance with increasing force and was similar to result of experimental value.

The purpose of this study was to determine the optimal mixing conditions of soybean oil and bread crumbs mixture for pork patty. The experiment was designed according to the central composite design of response surface methodology. There were ten experimental points, including two replicates for soybean oil and bread crumbs. The physicochemical and mechanical analyses of each sample, including pH, cooking loss, thickness increase, moisture content, lightness, hardness, adhesiveness, springiness, chewiness, and gumminess showed significant differences (p<0.05). The results of sensory evaluation showed significant differences in tenderness, juiciness, and overall quality (p<0.05). The optimum formulation calculated by numerical and graphical method was 13.61 g of soybean oil and 6.35 g of bread crumbs. The results obtained in this study will be useful to the meat industry, which tends to decrease the saturated fatty acid content with a concomitant enrichment in the unsaturated fatty acids content.

In this paper, we propose an efficient real-time multi-user input processing algorithm and protocol for supporting a number of different types of user input from various input devices. The main objective of this multi-user input processing algorithm and protocol is to support multiple users to interact simultaneously with the interactive digital content using a variety of user input devices. This protocol is composed of two parts: the input terminal and the server. The input terminals are connected to input devices and the 1:1 value obtained by the selection, calibration, integration, analysis and then transmission to the server to be used for the user input to the contents. The server processes multi-user input information and applies the input processing algorithm to identify the user and then pass input information to the desired application. This paper presents the design and implementation of the multi-user input processing algorithm and protocol. It also describes how to build and execute a multi-user interactive Unity3D application based on this algorithm.

This study was performed to determine the purification yield, color value, and total anthocyanin content of purifiedanthocyanins from Bokbunja byproducts for analyzing the optimal conditions of purification processing by responsesurface methodology (RSM) based on HCl or trifluoroacetic acid (TFA) concentration as an acidulent and ethanolconcentration as an eluent.

As a replication study of Hanaoka and Izumi (2012), the present research investigated the process of learners’ noticing of problems in their interlanguage (IL) while they were producing the second language (L2) and their process of relevant input provided in the form of two types of feedback (i.e., reformulation and a model text) in L2 writing. The data were collected from twenty-five university students in Korea, and they engaged in a four-staged picture description task consisting of the writing stage (Stage 1), the comparison stage (Stage 2), the immediate revision stage (Stage 3), and the delayed revision stage (Stage 4). It was found that output triggered learners’ noticing of problems; however, the problems did not always show up overtly in their writing. Some problems were manifested in writing (i.e., overt problems), while some were hidden (i.e., covert problems). A model text and reformulation played somewhat different roles in offering the solutions to the problems: a model text provided more solutions to covert problems while reformulation provided more solutions to overt problems. And, the extent of learners’ noticing was associated with the types of problems (overt vs. covert problems) and feedback (i.e., models vs. reformulation). However, the types of problems and feedback were not related to the rate of incorporation of feedback into subsequent writing.

This study introduces the web-camera image processing-based natural landmark extraction method for automatic welding using 3-axis stage. The welding is a highly significant process in the industries of shipbuilding, automobile, construction, machinery, and so on. However, it has been avoided due to poor working conditions such as fume, spatter, noise, and so on. For the automatic welding system, the web-camera is used to extract the natural landmarks which can give the relative coordinate to set up the initial position of the stage for the welding process. The Canny edge and Hough transformation have been used to extract the significant points for the natural landmark extraction in this paper.

귀리, 콩, 감자, 밀에서 유래한 다양한 식이섬유를 밀가루 대신 10-40%까지 대체함에 따른 수화능, 동적점탄성, 용매흡착능 및 in vitro starch digestion을 비교하였다. 귀리, 콩, 감자, 밀에서 유래한 다양한 식이섬유를 식이섬유의 대체비율이 증가할수록 수분흡착능과 팽윤력은 증가한 반면, 수분용해도는 감소하였다. 밀가루 대신 콩과 감자 식이섬유를 대체함에 따라 동적점탄성은 증가하였으나, 귀리와 밀 식이섬유 대체에서는 오히려 감소하는 경향을 보였다. 식이섬유 대체에 따른 밀가루의 용매흡착능 변화를 분석한 결과, 낮은 대체량의 귀리 식이섬유와 높은 대체량의 콩과 감자 식이섬유가 활용 가능성을 보였다. 원료별 식이섬유 대체 시 밀가루 겔의 전분소화 패턴은 식이섬유 대체비율이 증가함에 따라 glucose 방출은 감소하였으나, 원료별 특성에 따른 유의적인 차이는 없었다. 특히, 밀식이섬유를 제외한 귀리, 콩, 감자 식이섬유는 모두 RDS감소와 RS증가에 따른 pGI 저하를 보여 실제 식품소재로 활용 시 가공적성을 유지할 수 있다면 전분소화지연효과를 기대할 수 있음을 확인할 수 있었다. 한편, 식이섬유의 원료에 따른 식이섬유 조성과 전분소화 관련 특성 간 상관관계를 분석한 결과, 전분소화를 지연시키는 효과는 수용성 식이섬유보다는 불용성과 총식이섬유 함량이 중요한 인자임을 알 수 있었다.

In this paper, two kinds of advanced powder processing techniques Metal Injection Molding (MIM) and Direct Laser Forming (DLF) are introduced to fabricate complex shaped Ti alloy parts which are widely used for med- ical and aerospace applications. The MIM process is used to strengthen Ti-6Al-4V alloy compacts by addition of fine Mo, Fe or Cr powders. Enhanced tensile strength of 1030 MPa with 15.1% elongation was obtained by an addition of 4 mass%Cr because of the microstructural modification and also the solution strengthening in beta phase. However, their fatigue strength was lower compared to wrought materials, but was improved by HIP. Subsequently, the effect of feed- ing layer height (FLH) on the characteristics of the DLF compacts was investigated. In the case of 100 µm FLH, sur- face roughness was improved and nearly full density (99.8%) was obtained. Also, tensile strength of 1080 MPa was obtained, which is higher than the ASTM value.

Lamb waves are extensively used in plate-like structure inspection because of their guided nature. However, their dispersive properties often limit their use in flaw detection and other applications. Dispersion weakens and defocuses interrogating Lamb waves and makes it difficult to accurately interpret signals reflected from defects or boundaries. Time reversal (TR) processing can be applied to compensate for the effect of dispersive Lamb waves. Thus, the TR operation will enable the amplification of dispersive Lamb wave signals by signal compression in time. In this study, experiments are performed in order to examine the refocusing and recovering the initial input waveform in the long range propagation of dispersive Lamb waves in a plate. Two different time reversal processes (regular TR and reciprocal TR or inverse filtering) are tested and the experimental results are compared

고구마 칩의 최적 제조 조건 확립과 적합품종을 선정하기 위하여 신자미, 주황미 및 하얀미를 시료로 세절 두께(1~3㎜), 침지 당액 농도(15~30%), 데치기 시간(15~60 sec), 굽기온도(110~140℃) 및 굽기 시간(23~31 min)을 달리하여 칩을 제조하고, 각 조건별 관능평가와 파괴강도를 측정하였다. 품종 별 최적 제조 조건은 신자미는 각각 1 ㎜, 20%, 45 sec, 120℃ 및 31 min이었으며, 주황미는 1 ㎜, 25%, 45 sec, 130℃ 및 29min이었고, 하얀미는 1 ㎜, 25%, 30 sec, 130℃ 및 27 min이었다. 칩 제조 후 유리당 함량은 증가하였으며, maltose는 원료에서 검출되지 않았으나, 칩에서 3.85~13.50% 범위에서 증가하였고, sucrose 함량은 10.31~20.67% 범위에서 25.24~34.06% 범위로 칩 제조 시 증가하였다. 칩의 관능특성에 영향을 미치는 요인은 fructose, maltose, sucrose 함량, b-value 및 failurestress로 나타났다. 이러한 결과는 칩의 제조 시 적합한 품종의 선택과 품종에 따른 최적 제조 조건의 설정이 필요할 것으로 판단되며, 주황미가 칩의 제조에 가장 적합한 것으로 판단되었다.
