The purpose of this study was to compare the nutritional effects of resistant starch, cellulose and pectin on growth rate, metabolic energy and apparent digestibility in rats. Forty eight male Sprague-Dawley rats were randomly assigned to six dietary treatments, Rats were fed, ad libitum one of six experimental diets: 5% of resistant starch (RS), 5% of cellulose (CE), 5% of pection(PT), 2.5% resistant starch and 2.5% cellulose(RS+CE), 2.5% resistant starch and 2.5% pectin(RS+PT), and 2.5% cellulose and 2.5% pectin (CE+PT) during 4 weeks. The results obtained were as follows: body weight gain were higher in groups RS and CE, compared with that in the group PT, where other groups such as RS+CE, RS+PT and CE+PT showed no significant differences to the RS group. Food intake and food efficiency into showed the same patterns. Metabolic energy were similar in the RS and CE, and was the lowest the metabolic energy in the group CE+PT was significantly low. Apparent digestibility of protein was significantly higher in the group RS, compared with the groups CE and PT. Apparent digestibility of mixed dietary fiber groups such as the RS+CE, RS+PT and CE+PT group were also higher compared with the group PT. Apparent digestibility of lipid were significantly higher in the groups RS, CE and PT. Apparent digestibility of lipid in the mixed pectin groups such as the RS+PT and CE+PT growth rate, metabolic energy and apparent digestibility of lipid in the mixed pectin groups such as the RS+PT and CE+PT recorded the lowest, while that of the group RS+CE was significantly high. From above results, following was concluded: The growth rate, metabolic energy and apparent digestibility of protein and lipid of group RS were significantly higher in comparision with the group PT, while availability of energy nutrients of group CE was similar to that of the group RS. Also resistant starch fed with pectin(RS+PT) seemed to have increased the growth rate and the apparent digestibility of protein compared with those of the group PT fed with pectin(PT) alone, however RS+PT scemed to have the apparent digestibility of lipid.

A large scale automated material handling system (AMHS) is simulated using real industrial input data to analyze its performance so that one can scrutinize the critical factors that affect the AS /RS performance. The factors included in this study are line balancing efficiency, the distance between machines, and cycle time of the machines. The performance of AS /RS is measured in terms of R/M utilities that are latter used to classify the AS/RS structure into three types such as Good, Normal, and Poor. Among the three factors considered in this study, the line balance efficiency within each AS/RS is found as the most critical factor which statistically affect the AS/RS performance.

The purpose of this study was carried out to investigate the cause of sulfur dioxide occurrence, general element composition, sulfur compounds, heavy metals, macro- & micro-minerals, and oxidation-reduction potential (ORP) following baking time course of RS (RS1, RS2, RS3, and RS4) and mudflat solar salts (MSS). Sulfur dioxide ($SO_2$) and sulfite ($SO{_3}^{2-}$) were not detected in MSS or RS. However, sulfate ($SO{_4}^{2-}$) content significantly decreased in RS (29,878.15~36,097.45 ppm) compared to that in MSS (35,601.65 ppm). ORP was 181.15 mV in MSS, and 58.55 mV in RS1. Moisture content was 9.34% in MSS and 0.00% in RS with increased NaCl (94.77~95.77%). Moisture and NaCl contents showed no significant difference in RS. Insoluble and sandy residues were higher in RS than in MSS, whereas Ca and K showed no significant difference. Mg and Cl contents were higher in RS than in MSS. Br level was higher in MSS (628.1 ppm) than in RS (512.72~586.62 ppm), but there was no significant difference in $NO_3$. Heavy metals (Pb, As, and Hg) were more abundant in RS than in MSS, but levels were still safe. These results suggest that MSS and RS may increase protection against from $SO_2$ and $SO{_3}^{2-}$.

Automated Storage and Retrieval System (AS/RS), which is an element of Computer Integrated Manufacturing (CIM), is a widely used material handling equipment with conveyors and Automatic Guided Vehicles (AGVs). Until now the evaluation of operational policies of AS/RS and control algorithms is done theoretically or by computer simulations. In this study, a real-time control and monitoring software of an AS/RS is also developed by making actually moving AS/RS miniature. A PC-based real-time monitoring program can control the AS/RS directly through the communication port. The monitoring program has additional functions such as storage/retrieval management, inventory management, and statistics management. The program can not only collect the necessary statistics but monitor the current action of the AS/RS concurrently.

The RS-232C (Unbalanced serial) and RS-485 (balanced serial) are standard in serial communication. RS-485 uses a differential electrical signal, as opposed to unbalanced signals referenced to ground with the RS-232. Differential transmission, which uses two lines each for transmit and receive signal results in greater noise immunity and longer distances as compared to the RS-232C. The greater noise immunity and distance are big advantages in industrial environments. In general, one protocol on one serial interface is very normal application. In this study, we implemented multi protocols on one serial RS-485 interface and examine the performance and result with hanging multi equipments.

This study attempted to examine the application of retrograded starch (RS3) isolated from rice flour into Madeleine which is easy to make, supply enough energy and micro nutrients with adequate drinks, and prevent an adult disease. This could be a popular food to anyone regardless of age and gender who avoid rice and become high value-added, processed rice foods. For this, control Madeleine was made from wheat flour and an experimental one was made from 5 or 10% rice RS3 addition as well as wheat flour. Four different types of rice were produced from Premium Ho-Pyong Rice, that is, dry milled rice flour(RFD), soaked for 8 hours and milled, followed by air-dried rice flour(RFW), rice starch(RST), and retrograded rice starch or enzyme-resistant starch(RS3). The results found were as follows: Proximate compositions were decreased with soaking to make RFW, RST and RS3, compared to RFD. RS3 had the highest L, +a and ${\Delta}E$ with the lowest +b, changing it to a dark color, explaining the need for heat control during processing. At $80^{\circ}C$, the swelling power was shown in the order of RST>RFW>RFD>RS3 and the solubility of RS3 was the highest. There were significant differences in viscosities of peak, trough, cold, breakdown and total setback of all rice samples using RVA (p<0.001). Due to the pH of RS3, the Madeleine batter became acidic (p<.01) and expanded, resulting in more air cells and open texture. With an increasing RS3 level in Madeleine, several textural attributes among 'fresh' and 'stored at room temperature' Madeleine samples were significantly different by using Texture Analyzer. While the addition of RS3 in Madeleine did not significantly affect the sensory evaluation, indicating RS3 isolated from rice as a beneficial ingredient for processed rice products.

This paper illustrates a case study of PLC logic simulation in a car manufacturing system. It was developed to simulate and verify PLC control program for automobile panel AS/RS. Because car models become varied, the complexity of supply problem is increasing in the car manufacturing system. To cope with this problem, companies use the AS (automated storage) and RS (retrieval system) but it has logical complexity. Industrial automated process uses PLC code to control the AS/RS, however control information and control codes (PLC code) are difficult to understand. This paper suggests a PLC simulation environment, using 3D models and PLC code with realistic data. Data used in this simulation is based on realistic 3D model and I/O model, using actual size and PLC signals, respectively. The environment is similar to a real factory; users can verify and test the PLC code using this simulation before the implementation of AS/RS. Proposed simulation environment can be used for test run of AS/RS to reduce implementation time and cost.

Home-Network is an integrated network of the PC and all electric home appliances in the home so that they can communicate with each other. In the 21th century, here are various technology for Home Network environment such as HomePNA, IEEE 1394, Ethernet Lan and Bluetooth. For Home Network construction, generally, the standard series interface 'RS232' is used to make communication possible between electric home appliances. However Home network using RS232 has a problem. That is, All machines have to be connected to each other with RS232 using Point-to-Point mode. In this case, the system becomes complicated because we have to use circuits as much as there are machines and increased expenses. To improve this problem, In this thesis, designed home network using RS422 Multi-drop mode serial communication and controled it with embedded linux system. And connected RS422 with motors and sensors using PIC to make the home network virtual environment.
