As the amount of radioactive waste and related information to be managed are increasing, some organizations are trying or planning to computerize the management on radioactive waste. When we consider that information on safe management of radioactive waste should be used In association with national radioactive waste management project, standardization of data form and its protocol is required. Korea Institute of Nuclear Safety(KINS) will establish and operate nationwide integrated database in order to effectively manage a large amount of information on national radioactive waste. This database allows not only to trace and manage the trend of radioactive waste occurrence and in storage but also to produce reliable analysis results for the quantity accumulated. Consequently, we can provide necessary information for national radioactive waste management policy and related industry's planing. This study explains the database design which is the essential element for information management.

In this study, an analytical CRM for customer segmentation is exercised by integrating and analyzing the customer profile data and the access data to a particular web site. We believe that effective customer segmentation will be possible with a basis of the understanding of customer characteristics as well as behavior on the web. One of the critical tasks in the web data-mining is concerned with both 'how to collect the data from the web in an efficient manner?' and 'how to integrate the data(mostly in a variety of types) effectively for the analysis?' This study proposes a panel approach as an efficient data collection method in the web. For the customer data analysis, OLAF and a tree-structured algorithm are applied in this study. The results of the analysis with both techniques are compared, confirming the previous work which the two techniques are inter-complementary.

As a large number of distributed systems becoming more popular, interoperability, portability and security are becoming major concerns of modern computing. CORBA and object-oriented database which provide transparency of network and database are increasingly being used as the basis for distributed system to solve these problems. The two methods can help accomplish assurance of security by using a method-based access control technique or an attribute-based access control technique. These methods also enhance the unavailability or inefficiency caused by the delay of access process and bottleneck of the network due to the complex instance-based access control. We propose a security model on the type information based access control system that can enhance both security and availability by separating the functions delivered from CORBA and object-oriented databases. We apply the access control model specifically to enhancement of security system and also perform a test to verify the security and availability of our model.

As deployments of Flash memory are spreading out rapidly from tiny USB storages to large DB servers, interoperability become an indispensable requirement for Flash memory software architecture. For the purpose, many systems make use of the conventional FAT file system and FTL (Flash Translation Layer) software as a de facto standard. However, the tactless combination of the FAT file system and FTL does not satisfy diverse other requirements of a variety of systems. In this paper, we propose a novel reconfigurable integrated Flash memory software architecture, named INFLAWARE (INtegrated FLAsh softWARE) that supports not only interoperability but also reconfigurability and performance enhancement. Real implementation based experimental results have shown that INFLAWARE can achieve improvements of memory footprint up to 27% with an average of 19%, compared with the conventional FAT and FTL combination. Also, by using map_destroy technique, it can reduce response times of various applications up to 21% with an average of 10%.

If the software is not updated after the vulnerability is disclosed, it can continue to be attacked. As a result, the importance of N-day detection is increasing as attacks that exploit vulnerabilities increase. However, there is a problem that it is difficult to find specific version information in the published vulnerability database, or that the wrong version or software is outputted. There is also a limitation in that the connection between the published vulnerability databases is not good. In order to overcome these limitations, this paper proposes a method of building information including comprehensive vulnerability information such as CVE, CPE, and Exploit Database into an integrated database. Furthermore, by developing a website for searching for vulnerabilities based on an integrated database built as a result of this study, it is effective in detecting and utilizing vulnerabilities in specific software versions and Windows operating systems.

Today, interest in health information has risen overall due to the aging society, increased public interest in the quality of life, and the increased state's interest in reducing medical costs. Accordingly, efforts have been made across the library and information science in terms of academic research, libraries in terms of providing health specialized services, and the state, yet policies and strategies for providing the health related information in an integrated and systematic manner through the libraries have not been proposed with clarity to date. Thus, this study aimed to propose a method to provide the health information in an integrated manner by the libraries through the previous studies, policy studies, and case studies. Consequently, it proposes to build a system to integrate the health information, build an overall database of the health related information, develop and operate a health specialized library program, operate a general support center for the health information service, and build a cooperative network among the related departments and institutions for the health information service. The details proposed by this study is likely to contribute to developing services for improving the health of the citizens of this country.

This study was carried out to explore the accuracy of near infrared spectroscopy(NIRS) for the prediction of moisture content and chemical parameters on winter annual forage crops. A population of 2454 winter annual forages representing a wide range in chemical parameters was used in this study. Samples of forage were scanned at 1nm intervals over the wavelength range 680-2500nm and the optical data was recorded as log 1/Reflectance(log 1/R), which scanned in intact fresh condition. The spectral data were regressed against a range of chemical parameters using partial least squares(PLS) multivariate analysis in conjunction with spectral math treatments to reduced the effect of extraneous noise. The optimum calibrations were selected based on the highest coefficients of determination in cross validation($R^2$) and the lowest standard error of cross-validation(SECV). The results of this study showed that NIRS calibration model to predict the moisture contents and chemical parameters had very high degree of accuracy except for barely. The $R^2$ and SECV for integrated winter annual forages calibration were 0.99(SECV 1.59%) for moisture, 0.89(SECV 1.15%) for acid detergent fiber, 0.86(SECV 1.43%) for neutral detergent fiber, 0.93(SECV 0.61%) for crude protein, 0.90(SECV 0.45%) for crude ash, and 0.82(SECV 3.76%) for relative feed value on a dry matter(%), respectively. Results of this experiment showed the possibility of NIRS method to predict the moisture and chemical composition of winter annual forage for routine analysis method to evaluate the feed value.

Based on the survey for munitions companies, we have tried to find current state of the application of Korean military specifications(KDS) and their references for munition products, and how they can be improved for a better management system. On average, Korean munitions companies have 660 of KS, 18 of U.S. military specifications, and 5 of foreign standards, and annually spend about 0.4 million won for KS, but 1.3 million won for foreign standards. In addition, they have emphasized the necessity of the integrated management system for KDS and the related drawings.
