  • In this study, the effects of the fineness modulus of reactive aggregate on ASR expansion and ASR products have been investigated. The reactive aggregate used was metamorphic aggregate originated from Korea. ASR tests were conducted according to accelerated mortar bar test. The morphology and chemical composition of products formed in mortar bars, 5 years after the mortar bar test had been performed, were studied by scanning electron microscopy equipped with energy dispersive spectroscopy. Test results indicated that ASR expansion of mortar bars decrease in linear proportion to the fineness modulus of reactive aggregate. SEM images indicated that mortar bars showed reactive products formed in cement paste, within air voids and within cracks through particles except for the mortar bar with the fineness modulus of 3.25. The EDS analysis of the reactive products showed presence of silica, calcium and sodium, typical of ASR product composition.

  • This paper describes the calculation method to obtain the product composition of coal pyrolysis at high pressure and high temperature. The products of coal pyrolysis should be determined for the coal gasifier simulation, and this is the first step of the coal gasifier simulation. The pyrolysis product distribution greatly affects the coal gasifier efficiency such as carbon conversion, cold gas efficiency and the syngas composition at the outlet of the gasifier. The present calculation method is based on the coal ultimate/proximate analysis and several correlations among gasifier pressure, coal properties and pyrolysis products. The calculated products for 5 coals have been compared with those from the commercial pyrolysis model.

  • User Experience (UX) and Experience Innovation have been emphasized in the process of New Product Development (NPD). However, previous works which were conducted within the theme of UX mostly focused on the fragmentary aspects of user's experience in a specific usage-context only. For this reason, it is always hard to deal with questions on how to define the abstract concept of UX and how to apply this important keyword in actually NPD process both for satisfying potential users and for setting a market strategy. To address this issue, we focused on the fact that UX has an aspect of composition like pattern and structure. It means that we can understand the context of UX with clarifying characteristics of relations between user and experiential objects. Also, we referred to two sub-concepts of Complexity, Density and Centrality, as representative characteristics of relations in usage-context. Based on this theoretical background, we attempted to find UX design principles and concepts for NPD from the actual example cases of products and services in the real market. From these whole study process, we expect that our findings could have implications for academic and practical areas within the theme of Human-Centered Innovation.

  • In domestic and international, evaluation of product with Common Criteria(CC) for security product estimation is expanding standard of product estimation. This expansion is due to multi aspects of product versions. However, it is very difficult to approach the most suitable form of security estimation guide in the developer's perspective, because estimation basis presented to developers is indefinite. With this pending dilemma, we are presenting a composition product introduce definite security standard for information security products.

  • This study aimed to estimate the effects of replacing Mushroom By-Product (MBP) with Tofu By-Product (TBP) on the chemical composition, microbes, and rumen fermentation indices of Fermented Diets (FDs). The basal diet was formulated using MBP, TBP, rice bran, molasses, and inoculants. The MBP in the basal diet was replaced with TBP at 0, 5, and 10% on Dry Matter (DM) basis for the experimental diets. The experimental diets were fermented at $39^{\circ}C$ for 144 h. Chemical composition, pH, microbes, and rumen fermentation indices of the FDs were analyzed. With increasing TBP replacement, crude protein content of FDs increased (L, P < 0.001), whereas crude ash content decreased (L, P = 0.002). Lactic acid bacteria and Bacillus subtilis contents in the TBP-replaced FDs were higher than those in the control (P < 0.05), whereas pH level and mold count were lower (P < 0.05). With increasing TBP replacement, in vitro rumen digestibility of DM (L, P = 0.053) and neutral detergent fiber (L, P = 0.024) increased, wheres rumen pH changed (P = 0.026) quadratically. Rumen total volatile fatty acid (L, P = 0.001) and iso-butyrate contents (Q, P = 0.003) increased with increasing TBP replacement. In conclusion, this study indicates that the replacement of MBP with TBP could improve the quality of FD.

  • In this study, text mining was conducted on the product names of skirts, pants, shirts/blouses, and dresses to analyze the characteristics of keywords appearing in online shopping product names. As a result of frequency analysis, the number of keywords that appeared 0.5% or more for each item was around 30, and the number of keywords that appeared 0.1% or more was around 150. The cumulative distribution rate of 150 terms was around 80%. Accordingly, information on 150 key terms was analyzed, from which item, clothing composition, and material information were the found to be the most important types of information (ranking in the top five of all items). In addition, fit and style information for skirts and pants and length information for skirts and dresses were also considered important information. Keywords representing clothing composition information were: banding, high waist, and split for skirts and pants; and V-neck, tie, long sleeves, and puff for shirts/blouses and dresses. It was possible to identify the current design characteristics preferred by consumers from this information. However, there were also problems with terminology that hindered the connection between sellers and consumers. The most common problems were the use of various terms with the same meaning and irregular use of Korean and English terms. However, as a result of using co-appearance frequency analysis, it can be interpreted that there is little intention for product exposure, so it is recommended to avoid it.

  • This study was carried out to evaluate the nutritional properties of spreadable liver product. The composition of fresh hog liver used as raw material was 70.5% moisture, 5.2% fat, 20.3% protein and 1.2% ash. The composition of the spreadable liver product was 55.3% moisture, 19.4% protein, 21.6% fat and 3.7% ash. The total amino acid content of fresh liver was 18.69 g/100 g with glutamic acid at the highest level of 2.57 g/100 g. The total amino acid content of liver product was 18.03 g/100 g with glutamic acid at 2.28 g/100 g. The essential amino acid content was found to be 42% of total amino acids. The fatty acid analysis of fresh liver revealed oleic acid to be present at the highest level of 28% in the unsaturated fatty acid portion, and palmitic acid to be highest at 20.7% in the saturated fatty acid portion. The oleic acid content of the liver product was 40%, and the palmitic acid content was 20.4%. The level of cholesterol in fresh liver was 178.0 mg/100 g compared to 118.0 mg/100 g in the liver product. Regarding mineral analysis, the K and P contents of fresh liver were 362.2 mg/100 g and 339.1 mg/100 g, respectively, and 336.1 mg/100 g and 213.3 mg/100 g in the liver product, respectively. Many other minerals including Na, Mg, Ca and Fe were present in the product. Based on these results, the spreadable liver product made with hog liver was found to be a quality food with nutritional benefits and that is easy to consume.

  • This investigation was conducted to evaluate the shrimp flesh (SF) and shrimp by-product (SB) of the most abundant shrimp species (Metapenaeus affinis, Penaeus semisulcatus and Penaeus monodon) caught in Central Vietnam, with the emphasis on yield, gross and amino acid (AA) composition and effect of heat treatment. The results showed that the mean edible SF and SB (head and shells with tail) yields of the three shrimp species averaged 56.7 and 43.3%, respectively, of the total wet body weight, with the M. affinis generating the highest by-product yield (45.7%) and P. semisulcatus (40.6%) the lowest. Significant differences in dry matter (DM), crude protein (CP) and ash content were found between SF and SB. The DM content of SF (21.5%) was lower than of SB (24.9%) and the ash content (on a DM basis) of the SB in all shrimp species was more than three times that of the SF (p<0.05), whereas the CP content was almost twice as high in the SF as compared with the SB (p<0.05). The SB of the three species contained (on a DM basis) between 44.0 and 49.8% CP (p<0.05) and between 13.5 and 18.1% chitin (p<0.05). The Ca content of SB differed also between species (p<0.05). On average, the sum of AA in SB corresponded to 89.3% of the CP and essential AA accounted for about 50% of the total AA. The most abundant AA were arginine, aspartic and glutamic acids, which accounted for 33% of the total AA. Minor, but significant differences in some AA concentrations of SB between species were observed (p<0.05). With the exception of the DM and ether extract content, all other chemical constituents of entire shrimp, SF and SB were not significantly affected by heat treatment (p>0.05).

  • Boar sperminogen was purified from the acid extracts of the washed epididymal spermatozoa by gel filtration through a Sephadex G-100 column, followed by preparative SDS-PAGE. The 32 kDa sperminogen band was sliced out from the preparative SDS-PAGE and 32 kDa sperminogen was eluted from the gel matrix. The purified 32 kDa sperminogen was subjected to amino acid composition analysis. The amino acid composition of the 32 kDa boar sperminogen showed significant differences from that of either boar proacrosin or ${\beta}-acrosin$, which signifies that 32 kDa sperminogen might not be a breakdown product of proacrosin-acrosin system and that the 32 kDa sperminogen is a different protein from proacrosin-acrosin system.
