This study aimed to examine quality properties of muffin by the amount of addition of Korean whole wheat flour (0%, 25%, 50%, 75%, 100%) as there is increasingly higher interest in the healthy food. The effect of Korean whole wheat flour were evaluated in terms of height, volume, weight, specific volume, baking loss rate, colorimeter, and sensory evaluation. Texture and moisture contents of muffins when storage (1, 3, 5 days) was measured. As the ratio of Korean whole wheat flour increased, the baking loss rate and weight increased, whereas the volume and specific volume was not significant. During storage, moisture content of muffins decreased significantly. The addition of Korean whole wheat flour increased lightness (L value) of crust and crumb decreased, whereas redness (a value) and yellowness (b value) increased. The control group (CON) showed the highest springiness lowest hardness. The muffin with 25% of Korean whole wheat flour (WHF25) in test group showed the high springiness low hardness. According to the sensory evaluation, the control group showed the highest score in terms of taste, however WHF25 showed the highest score in appearance, color, flavor, texture and overall acceptance, WHF25 showed the best result and the optimum addition of Korean whole wheat flour. Furthermore, this study proposes the possibility of development of various confectionery with using Korean whole wheat flour.

This study investigated the quality characteristics of muffins prepared with tagatose. The effect of tagatose were evaluated in terms of height, volume, weight, specific volume, baking loss rate, moisture contents, colorimeter, sensory evaluation, and texture of muffins during storage (1, 3, 5 days) and texture was measured using a texture analyzer. As the ratio of tagatose increased, the volume, specific volume, baking loss rate, and height decreased, whereas moisture content increased. During storage, control without tagatose showed the highest springiness lowest hardness by TPA, whereas hardness of muffins increased and springiness decreased as the contents of tagatose increased. Lightness of crust and crumb decreased significantly as contents of tagatose increased. According to the sensory evaluation, the control group showed the highest score in terms of texture but was not significant with 2% tagatose (T2). For appearance, color, flavor, taste, and overall acceptance, T2 showed the best result.

Recently, Low Impact Development (LID) is being used in Korea to control urban runoff and nonpoint source pollution. In this study, we evaluated the reduction of surface runoff from a study area, as the effect of connecting three bioretention as LID-BMP. Surface runoff and storage volume of bioretention is estimated by the Curve Number (CN) method. In this study, the storage volume of bioretention is divided by the volume of surface runoff and precipitation which directly enters the bioretention. The ratio of captured surface runoff volume to storage volume is highly influenced by the ratio of drainage area to surface area of bioretention. The high bioretention surface area-to-drainage area ratio captures more surface runoff. The ratio of 1.2 captures 51~54% of the total surface runoff, ranging from 5-30cm of bioretention depth; a ratio of 6.2 captures 81~85%. Three connected bioretentions could therefore captures much more runoff volume, ranging from $35.8{\sim}167.3m^3$, as compared to three disconnected bioretentions at their maximum amount of precipitation with non-effluent from the connecting three bioretentions. Hence, connecting LID-BMPs could improve the removal efficiencies of surface runoff volume and nonpoint source pollution.

This paper presents a network-attached WORM(Write Once Read Many) storage system whose purpose is to protect sensitive data that should not be accessed by accidental/intentional intrusion. In our storage system, the sensitive data would be marked and be stored into a specific WORM volume. Furthermore, with the associated WORM mark, the data whose WORM life cycle has been expired would automatically be moved to the general-purpose disk space, without interfering any other tasks, to save the WORM volume space. Our WORM storage system was integrated to the NAS product.

It is generally recognized that Video On Demand (VOD) service will become a promising interactive service in B-ISDN. We consider a hierarchical two level network architecture for VOD service. The first level consists of connected Local Video Servers(LVSs) in which a limited number of high vision programs are stored. The second level has one Central Video Server(CVS) containing all the programs served in the network. The purpose of this paper is to analyze the network traffic and to propose the storage policy for LVSs. For this purpose, we present an analysis of program storage amount in each LVS, transmission traffic volume between LVSs, and link traffic volume between CVS and LVSs, according to changing the related factors such as demand, the number of LVSs is also presented on the basis of the tradeoffs among program storage cost, link traffic cost, and transmission cost.

Since cryogens are stored at very low temperatures, the cryogenic storage systems are quite sensitive to heat leaks. Even though the vessel operated under sealed condition with vacuum insulation and reflective coatings are used, the heat leakage into the vessel is still unavoidable. Therefore, this paper concerns with numerical study of self-pressurization used to analysis the optimum design with the variation volume fraction, effect of heat flux and storage pressure of liquid nitrogen. The result shows that as the volume fraction increases, the pressure rise reduces and the relatively at atmosphere pressure is better than the higher one. In addition, higher heat flux leads the pressure rise increases faster than low one. The additional of heat pipe system to reduce the pressure rise rate also has been done. By this comparison, the optimum design for storage umbilical cord blood can be selected.

A speckle pattern from an optical fiber is used for a reference beam in writing and reading a volume hologram. The photorefractive volume hologram with this scheme shows good spatial selectivity for spatial(shift) multiplexing because the speckle pattern in writing and reading a hologram looses correlation with a small spatial shift. This scheme has the insensitivity to axial movement. The data storage system with this scheme will have a high storage density and a good stability in operation. We theoretically analyze the diffracted beam from a volume hologram recorded with the speckle pattern from the optical fiber. Experimental results are presented and compared with numerical analysis.

The purpose of this study is to analyse whether the waste disposal volume level in the construction waste disposal industry makes a different effect on earnings management behaviour by size of the licensed storage capacity and by location of the waste disposal site. The empirical results of this study are as follows. First, the waste disposal volume significantly influences earnings management behavior. When it comes to the size of licensed storage capacity in the small-sized capacity firms, the smaller waste disposal volume firms make more aggressive earnings management by using discretionary accruals. On the other hand, in the large-sized capacity firms, more waste disposal volume firms report higher earnings by adjusting more discretionary accruals. Second, the effects of waste disposal volume on the earnings management show different pattern depending on the location of waste disposal site. When the firms are located in the non-capital regions, the smaller waste disposal volume firms report higher earnings by adjusting discretionary accruals as well as by using real activities earnings management. However, the firms located in the capital regions show more aggressive earnings management when they have higher waste disposal volume level.

Data storage related with writing and retrieving requires high storage capacity, fast transfer rate and less access time. Today any data storage system cannot satisfy these conditions, however holographic data storage system can perform faster data transfer rate because it is a page oriented memory system using volume hologram in writing and retrieving data. System can be constructed without mechanical actuating part so fast data transfer rate and high storage capacity about 1Tb/cm3 can be realized. In this research, to correct errors of binary data stored in holographic data storage system, a new method for reduction errors is suggested. First, find cluster centers using subtractive clustering algorithm then reduce intensities of pixels around cluster centers. By using this error reduction method following results are obtained ; the effect of Inter Pixel Interference noise in the holographic data storage system is decreased and the intensity profile of data page becomes uniform therefore the better data storage system can be constructed.
