ERP Systems can not meet All the Requirements that Needed in Their Enterprise Organizations. After the System Introduced, when it perates with Existing Systems or with New Systems, the Need for Strong Interface Technology along with the Appearance of the ERP have been gradually Increased. Interface Technologies for SAP R/3 Systems integrate Mulltiple R / 3 Systems and non R / 3 Systems, and play Important Role in Expanding the Company's Business Process. New VBA Approach was implemented as the Data Interface Design between SAP R / 3 and Other Systems. It proved to Reduce the Feeling of Resistance from User's Point of View. It also Proved to Improve the Operational Efficiency with More Convenient Input and Output Manner of Purchase Request Data.

Many companies have attempted to strengthen competitiveness by introducing information technology ERP system in a changing and global competitive business environment. However, ERP systems can not meet all the requirements that occur in the enterprise. After the system introduced, When it operates with existing systems or with new systems, the need for strong interface technology along with the appearance of the ERP have been gradually increased. In this paper, we selected SAP R/3 system as a typical ERP system. Among the modules of SAP R/3, MM module was chosen. Interface technologies for SAP R/3 Systems integrate mulltiple R/3 systems and non R/3 systems, and play important roles in expanding the company's business process. VBA approach was implemented as the data interface design between SAP R/3 and other systems. It proved to reduce the feeling of resistance from user's point of view. It also proved to improve the operational efficiency in a convenient input and output manner of purchase request data.

Among the various ERP solutions, SAP R/3 solution has been chosen because SAP system follows global standard processes which include most of business solutions for various industries. The ERP education is limited by learning theory only and they are not sufficient for understanding wide scale of business processes. Real world scenarios with hands on experience approach will be the core aspect of this article. As per real world scenarios, "ChungBuk Motors. Corp." has been created and students are asked to create the organization structure and the procurement process for this virtual enterprise. As a result, students attending this class showed better understanding of overall ERP system comparing to the students attended other ERP classes. The hands-on experience with real-world scenarios proved that it is most practical and efficient solution for educating ERP system.

The present study was carried out to investigate the effects of Panax ginseng saponin extracts on the dexamethasone-induced apoptosis of mouse thymus in vivo and mouse thymocytes in vitro. The saponin fractions of red ginseng (R-SAP) and white ginseng (Wl-SAP) were provided by the Korea Ginseng & Tobacco Research Institute, and the other saponin fraction of white ginseng (W2-SAP) was extracted in our laboratory. 1. The male ICR mice (3~4 wk old; weighing 15$\pm$2 g) were given by each saponin fraction of 5 mg/kg/ day for 4 days, and at one hour after the last treatment, they were injected by deuamethasone (5 mg/kg : DX). The mouse thymus was extracted at 6 hours after DX injection, and they were stained with hematoxylin-eosin reagents and an Apop-Tag kit, respectively, and the thymocytes prepared from it were labelled with anti-mouse FITC-anti-CD4 and anti-mouse PE-anti-CD8 and then analyzed by fluorescence activated cell sorter (FACS). DX-induced reduction of thymus weight was significantly attenuated by W2- SAP but was not affected by other saponin fractions. And DX-induced apoptotic death of thymocytes, appeared in the histologic findings of the thymus, was inhibited by the saponin fractions and the order of these inhibitory potencies was R-SAP》W2-SAP>Wl-SAP. However, in respect of T cell receptors, the differentiation of thymocytes seems not to be changed by treatments with DX or/and the saponin fractions. 2. In the primary thymocyte culture, the DX-induced reduction of thymocyte MTT values was rather greater in RPMI 1640 medium of IWc fetal bovine serum (FBS) or horse serum (HS). In addition, the DX-Induced MTT reduction was significantly inhibited by R-SAP or W2-SAP, in the culture using that medium of 5% FBS or HS. But these saponin fraction did not effected the DX-induced reduction of thymocyte MTT value in primary culture of 10% FBS or 10% HS. These results suggest that R-SAP and some W-SAP fractions may protect thymocyte from stress or glucocorticoisteroid-induced death of them.

Effects of gamma irradiation on microbiological changes of Gorosoe sap were characterized during a post-irradiation storage at $4^{\circ}C$. The aseptically collected sap was irradiated and stored at $4^{\circ}C$ for 0 to 60 days and analysed for standard plate counts and 16S rDNA. There were significant differences in the total number of colony forming units(CFUs) of bacteria between irradiated and non-irradiated control sap. Bacteria of non-irradiated sap were present at levels of $1.5{\times}10^4{\sim}2.3{\times}10^8\;CFU/m{\ell}$, whereas no viable microbial cells were detected in sap after 10 kGy of irradiation during storage. According to the 16S rDNA sequence analysis, bacterial community structures decrease with time and the most abundant strain was Pseudomonas species. Our results suggested that gamma irradiation can be used to enhance the shelf-life of Gorosoe sap.

The sap outflow characteristics of Juglans sinensis and J. mandshurica were investigated to evaluate the optimum pruning period of walnut tree that there is a sap spill on dormant. The total period of sap outflow were 34 days for both J. sinensis and J. mandshurica. Total amount of sap outflow per tree in J. sinensis and J. mandshurica were 2,922 mL/tree and 3,135 mL/tree, respectively and the period of sap outflow and non sap outflow between two species were similar. ANOVA analysis showed that the amount of sap outflow was significant differences with day of sap outflow but there were no significant differences between species. From the correlation analysis between air-temperature and sap outflow, daily minimum temperature showed a positive correlation at the 1% level of significance (r=0.56 and r=0.46) for both J. sinensis and J. mandshurica. When branch of walnut tree that diameter is 5 cm cut on the period of sap outflow, the sap flowed down the longest period (48 days) but the sap outflow was not observed after budburst. Therefore, our study supported that the pruning have to avoid the period of sap outflow to reduce sap outflow of walnut tree.

Effects of high pressure processing on physicochemical and microorganisms properties in birch sap were investigated using variable high pressure processing conditions. The viable cell counts of untreated birch sap was 4.0 log CFU, whereas high pressure processed sap were not detected. In birch sap was treated with 450 to 550 MPa, microorganisms were not detected during storage period, and physicochemical properties as well as color were slightly changed. The more processing time and pressure, its quality variations were more stable and then its optimum processing condition was determined with 120 sec at 550 MPa. The microorganisms and physicochemical properties of treated birch sap were investigated during storage at $5^{\circ}C$ and $10^{\circ}C$ for 45 and 28 days. Changes of physicochemical properties of treated birch sap were smaller than those of the untreated, but viable cell count were not detected during storage period. As for pH, $^{\circ}Brix$, and turbidity result of birch sap, quality shelf life of control and treatment were 4 and 24 days, respectively. Especially, ${\Delta}E$ value of instrumental color was untreated birch sap 4 days similar with the high pressure processed it for 28 days. These results indicated that the high pressure processing can be used as an effective method to improve the shelf life of birch sap.
