Setting is an important process for the control of surimi quality in industry because it can improve the gel texture and water-holding capacity of surimi-based products. Therefore, the effect of setting on giant squid surimi-based product was analyzed via a mixture model. Konjac flour and microbial transglutaminase were used as texture enhancers. Both texture enhancers improved the texture and water retention ability (WRA) of giant squid surimi-based products, while decreasing the whiteness. Setting also improved the gel texture and WRA, while having no effect on the whiteness. Based on the sensory evaluation, the product with gel texture enhancers was better than the control and similar to commercial surimi products. Therefore, the applications of gel texture enhancers and setting are very important for the manufacture of giant squid surimi-based products.

Three-dimensional (3D) microfabrication process using two-photon polymerization (TPP) is developed to fabricate the curved microstructures in a layer, which can be applied potentially to optical MEMS, nano/micro-devices, etc. A 3D curved structure can be expressed using the same height-contours that are defined by symbolic colors which consist of 14 colors. Then, the designed bitmap figure is transformed into a multi-exposure voxel matrix (MVM). In this work a multi-exposure voxel matrix scanning method is used to generate various heights of voxels according to each laser exposure time that is assigned to the symbolic colors. An objective lens with a numerical aperture of 1.25 is employed to enlarge the variation of a voxel height in the range of 1.2 to 6.4 um which can be controlled easily using the various exposure time. Though this work some 3D curved micro-shapes are fabricated directly to demonstrate the usefulness of the process without a laminating process that is generally required in a micro-stereolithography process.

Objective: Many drug or non-drug therapies are reported to be effective in reducing the severity of attention deficit/hyperactivity disorder (ADHD). The aim of this study was to assess the effect of color and pattern on the severity of ADHD in young ADHD patients. Method: We randomly assigned 30 children into two groups and had them participate in 15-minute block play sessions once in a week. The experimental group used blocks with green (3G, Munsell color system) circle patterns on them, while the control group played with plain white blocks. We also provided a set of playing cards with the corresponding patterns. This trial continued for 4 weeks and 29 children (96.7%) completed. The primary outcome measurement was the ADHD rating scale-IV and was evaluated on every visit. Results: After the trial, ADHD score decreased in both groups but not significantly ($34.4{\pm}8.0$ to $30.0{\pm}4.3$; $34.0{\pm}6.0$ to $30.3{\pm}3.2$). However, there were significant differences in 4 items of ADHD rating scale between the two groups. These consisted of 3 inattention (Q3, Q7, Q15) and 1 hyperactivity-impulsivity (Q12) items and the reduction between the first and final visits was significant (p=0.0240, p=0.0498, p=0.0237 and p=0.0012 respectively). Conclusion: Repeated exposure to a green circle pattern might not influence the total score of ADHD rating scale but reduced 3 inattention items and 1 hyperactivity-impulsivity significantly in children with ADHD. Proper visual stimuli are partially helpful for pediatric ADHD.

Natural preservative agents are generally made of antibiotic substances that are extracted from plants. They are used mainly to keep in an original good state food, natural cosmetic goods and medicines which are likely to get rotten. The purpose of this study is to investigate whether natural preservative agents can be applied to fabrics for the preservation of textile cultural properties. For the purpose, this researcher experimented with a certain natural preservative agent which was developed to preserve natural cosmetic goods. The study found that when treated with the foresaid natural preservative agent whose ratio to water was 1%, fabrics showed little changes in color and tensile strength, almost neutral pH, high antibiosis and anti-fungus and high resistance to Bacillus cereus that is much detrimental to silk fabrics. As a part of the study, a preliminary test on the possibility of using natural preservative agents to preserve textile cultural properties, found that when kept covered up with the 1% natural preservative agent-treated fabrics for 72 hours, excavated textile relics showed a dramatic decrease in microbial growth.

The Geostationary Ocean Color Imager (GOCI), the first geostationary ocean color observation instrument launched in 2010 on board the Communication, Ocean, and Meteorological Satellite (COMS), has been generating the operational level 1 data. This study describes a methodology for creating the GOCI true color image and data processing software, namely the GOCI RGB maker. The algorithm uses a generic atmospheric correction and reprojection technique to produce the color composite image. Especially, the program is designed for educational purpose in a way that the region of interest and image size can be determined by the user. By distributing software to public, it would maximize the understanding and utilizing the GOCI data. Moreover, images produced from the geostationary observations are expected to be an excellent tool for monitoring environmental changes.

In this study, we tried to analyze the fusion parameters required to produce a high-resolution multispectral image using an image fusion technique and to suggest global fusion parameters. We analyzed the linear regression coefficients that can simulate the panchromatic image, and the fusion coefficients required for producing the fusion image. When the fusion images were produced using the representative fusion parameters, it was confirmed that the difference in DN value between each fusion image was quantitatively smaller than when the optimal fusion parameters were used. Therefore, this study can minimize the regional characteristics reflected in the fused image.

The substitution effects of broccoli powder for flour in the preparation of sponge cake were determined by physicochemical and sensory analysis. The specific gravity and viscosity of the cake batter and cooking loss of the cake increased with an increasing amount of broccoli powder, whereas specific loaf volume and moisture content of the cake decreased. Lightness, redness, and yellowness of crust and crumb decreased with increasing broccoli powder content. A texture analyses revealed that the hardness, chewiness, gumminess, adhesiveness, and fracturability of the cake tended to increase in proportion to the amount of broccoli powder in the formula. In the sensory evaluation, cake prepared with 5% broccoli powder was similar to the control in moistness, softness, chewiness, and springiness. These results suggest that adding 5% broccoli powder is the best substitution ratio for sponge cake.
