The objective of this experiment was to compare the effects of green tea by-product and green tea probiotics on the growth performance, meat quality and immune response of finishing pigs. A total of 72 crossbred "Landrace$\times$Yorkshire" finishing pigs with an average of 76 kg body weight were assigned to 4 dietary treatments in a completely randomized design. Each treatment had 3 replications with 6 pigs per replication. The four dietary treatments were control, antibiotics (control diet with 0.003% chlortetracycline added), and diets containing 0.5% green tea by-product or 0.5% green tea probiotic supplementation. Weight gain was increased in 0.5% green tea probiotics treatment compared to others, but there was no significant difference (p>0.05). The incorporation of 0.5% green tea probiotics to diets reduced the feed conversion ratio in finishing pigs (p>0.05). The incorporation of 0.5% green tea by-product into the pig diet reduced the crude protein and fat contents of the meat (p>0.05). Pigs fed diets containing 0.5% green tea probiotic supplementation had lowered meat TBA values compared to those fed 0.5% green tea by-product (p<0.05). The proliferation of spleen cells stimulated with Con A (concanavalin: 0.1, 0.3, and $1.0{\mu}g/ml$) significantly increased with 0.5% green tea by-product treatment compared to antibiotic treatment (p<0.05), but was significantly decreased in 0.5% green tea probiotics treatment compared to the antibiotic treatment (p<0.05). When stimulated with $1.0{\mu}g/ml$ Con A, splenocyte production of IL-6 from pigs treated with 0.5% green tea by-product or green tea probiotics was significantly increased compared to the antibiotic treatment group (p<0.05). Splenocyte production of TNF-${\alpha}$ after treatment with $1.0{\mu}g/ml$ Con A was significantly higher following 0.5% green tea probiotics treatment (p<0.05), while TNF-${\alpha}$ production after $10.0{\mu}g/ml$ LPS (lipopolysaccharide) was significantly higher in the 0.5% antibiotic treatment group (p<0.05).

In this note by considering the notions of F-polygroups, the product of F-polygroups, F-subpolygroups and (weak) normal F-subpolygroups two questions are given. Then by an example it is shown that the answer of one of the questions (posed in the paper [12]) is in general negative. In other words, the product of two normal F-subpolygroups need not be normal.

In the present article we consider multiparameter maximal averages and discover the crucial roles played by the number of parameters in their boundedness properties. The problem we shall deal with is initiated by Rubio de Francia [8] and will be in the spirit of an inductive extension to multiparameter cases, in which tools of our study rely on the theory of Harmonic Analysis on product spaces. Suppose that $d_\mu$ is a complex Borel measure supported on a compact subset S of $R^N$ having total mass one, $\smallint_S d_\mu = 1$.

Recently, Jianxin Liu, Hao Pan and Yong Zhang in [On the integral of the product of the Appell polynomials, Integral Transforms Spec. Funct. 25 (2014), no. 9, 680-685] established an explicit formula for the integral of the product of several Appell polynomials. Their work generalizes all the known results by previous authors on the integral of the product of Bernoulli and Euler polynomials. In this note, by using a special case of their formula for Euler polynomials, we shall provide several reciprocity relations between the special values of Tornheim's multiple series.

Here we introduce so called Reference code-weighted sum of all PN codes used in the system-. We do inner product operation between received PN code and Reference code rather than locally generated PN code in the receiver. Acquisition process can be accomplished by only one inner product during full period of PN code. It's essential innovation against present method which can be viewed successive hypothesis test by inner product for entire candidate PH codes set. Well -defined decision region makes it possible. We suggest the. criterion fur designing the decision region and find a condition for weight (coefficient) of Reference code.

The present topic in pharmaceutical industry is to establish Quality Assurance System for medicinal product Therefore, the most important and urgent subject to be solved in the field of the manufacturing industry is to establish, implement and maintain the control system for ensuring uniformity of medicinal product. In case of solid dosage forms for internal use, its quality was controlled by disintegration test, etc but at present bioavailability could be predicted with dissolution test and so the assurance of its uniformity should be prerequistie to preserve suitable dissolution of the manufactured medicinal product.

The goal of this study is leading discussion on emotional design focused on product domain and approaching it through a practical way so that it'll be able to help designers in their real design work when they design products in an emotional way. Discussions on emotions are remaining on abstract levels and only focusing on 5 senses even though the importance of emotions are increased. But much more is needed to apply emotions in the product domain because these are not the proper forms for applications and they only cover limited parts of it. Therefore, in this study we proposed the notion of 'Emotionalized Product' and defined it into a practical level. We extracted 5 useful frameworks of 'Emotionalized Product(EP)' as a results; EP Media, EP Procedure, EP Level, EP Character, and EP Value. Then we clarified EP with these frameworks. After that, we extracted 2 frameworks: Domain Structure, and EP Opportunity, to combine EP with a real product. Finally we proposed the EP Design Process consisted of Inductive and Deductive Process based on previous work. It can be shared by designers as a base of designing system, and it also can be helpful to design products more successfully with an emotional approach.

PL (Product Liability) refers to the legal responsibility of a manufacturer or seller for bodily injuries or property losses caused by product defects. Therefore, it is important for companies to construct a product liability response system that strategically manage and effectively adapt to product liability. A PL response system refers to companywide operations of PL prevention (PLP) measures, product safety (PS) measures, and PL defense (PLD) measures appropriate for a company's scale and environment. To establish an enterprise product liability response system, each essential component of corporations should be systematically operated and maintained considering the scale and characteristics of the corporations. Essential components of PL response system is Strategy, Organization, Training, Technology, Investment, and Awareness. Role of essential components is that companies need specific strategies to secure product safety and protect customers from product defects, and appropriate organizations must be composed for effective operation of such strategies. The objective of this paper seeks to examine the relationships among the essential components of the product liability response system and PL performance. PL performance consists of positive performance and negative performance. In particular, positive performance include increased efforts in product or process innovation such as strengthening research and development (R&D) to produce safer products without defects. In order to carry out this research we obtained 98 questionnaire of manufacturing company. A summary of the analyses is as follows: First, the awareness and technology among essential components affect significantly to the positive performance. Second, the awareness and strategy among essential components negative affect to the negative performance.

The current study extends previous research by investigating the role of shopping experience and product type within the direction of online reviews and information reliability and product attitude. To test the hypotheses, this study conducted experimental designs. Direction of online reviews and product type were manipulated as between-subject factors. Then participants were classified into high or low group based on their shopping frequency. Dependent variable was information reliability and product attitude. The results indicate that direction of online reviews have a significant effect on both information reliability and product attitude. In addition, consumers' shopping experience also shows a moderating effect between the direction of online reviews and the dependent variables. Furthermore, product type also shows a moderating effect on the information reliability, yet not on the product attitude. The results of this study contribute to the literature as a new attempt to examine the direction of online reviews in the online shopping area. We also indicated the limitations of this study, and suggested the future research directions.
