Web-based information resources should be managed and used methodically in the same manner as the paper-based resources are managed and used. It is necessitated by the prevalence of web-based delivery of a variety of information. To develop a web-based digital collection, it is critical to establish a set of standardized evaluation criteria for web-resources. The evaluation criteria needs to include authority, trustworthy, reliability, functionality, relatedness, accessibility, structure, design, user support, and security related matters. However, it is also necessary to have certain flexibility to either emphasize or include particular evaluation criteria to reflect varying characteristics of the web resources especially for the purpose of developing an effective digital collection. In addition, it is essential to review the evaluation criteria with respect to value, demand, duplication prevention, and intellectual property, which are relevant to the web-based digital collection development. Finally, various strategies were suggested as means to develop more effective web-based digital resource collection. These strategies include organizing a selection committee to ensure the objectivity and consistency in web-resource evaluation; developing a model for web-based digital resource collection; sharing new standards, protocols, markups, and metadata with other digital libraries; and developing user-centered digital resource collection.

This study presents an RTS(Real-time Traffic System) based on an LBS(Location Based Service) using 5.8~5.9GHz RSU(Road Side Unit). The proposed LBI(Location based Broadcast system on ITS) is a local information-based service supported by RSU for drivers, which has a feature of convergence between T-DMB system and ITS-based RTS. The convergence of local broadcasting station and ITS is realized by two-way communication and supports LBS(Location Based Service) by identifying of vehicle's location using RSU. Real-time information delivery and various services could be provided by information exchanges between LMM and local broadcasting stations. Furthermore, conventional technical limitations have been solved mutually such as transmission area limitation in RTS and one-way communication problem in T-DMB. This support real-time two-way communication to each driver. Therefore, it can be expected that traffic dispersion effects and services expansion for drivers by RTS and LBI. Finally, it is proposed to built and implement test-bed around institute.

As IT is also recognized as assets, IT assets management system is trying to introduce for the management and operation in domestic enterprises and public institutions. The general assets management system was introduced in domestic companies, but because it managed mainly the only simple information about the assets, there were a lot of operational difficulties of the assets. In order to operate effectively the IT assets used in special business such as bank, prosecutors, railway, etc the classification system of IT assets based on the EA was needed first of all. Accordingly, in this paper, we classified IT assets systematically according to the EA meta model Application Guide V1.4 in consideration of the characteristics about the IT asset business for A public institution, and performed to improve the operating costs and efficiency by implementing a web-based IT assets management system for this public institution.

A linguistic case-based fuzzy reasoning (LCBFR) based on standardized parametric membership functions (SPMF) is proposed. It provides an efficient mechanism for a fuzzy reasoning within linear time complexity. Thus, it can be used to improve the speed of fuzzy reasoning. In the process of LCBFR, linguistic case indexing and retrieval based on SPMF is suggested. It can be processed relatively fast compared to the previous linguistic approximation methods. From the engineering viewpoint, it may be a valuable advantage.

Two types of carbon fiber based high modulus- and isotropic-pitch were exposed to isothermal oxidation in air and $CO_2$ gas and the weight change was measured by TGA apparatus. The kinetic equation was introduced $f=1-{\exp}(-at^b)$ and the constant b was obtained in the range of 1.02~1.68 for the isotropic fiber and obtained 0.91~1.93 for the high modulus fiber respectively. In considering the effect of the atmosphere for isothermal oxidation, the value of the constant b obtained in the carbon dioxide was higher than that obtained in the air. Therefore, it was found that the pitch based carbon fiber shows sigmoidal characteristic when it is oxidized in the carbon dioxide. In addition, it was also found that $k_f = 0.5$, which was reaction constant at f = 0.5, was a very useful parameter for evaluation of the oxidation reactivity of pitch based carbon fibers. According to the consideration, it is suggested that the conversion-time curves of the pitch based carbon fibers are correlated by normalized equation $f=1-{\exp}(-A{\tau}^B)$, where ${\tau}=t/t_f= 0.5$.

The main objective of pathologists is to achieve accurate lesion diagnoses, which has become increasingly challenging due to the growing number of pathological slides that need to be examined. However, using digital technology has made it easier to complete this task compared to older methods. Digital pathology is a specialized field that manages data from digitized specimen slides, utilizing image processing technology to automate and improve analysis. It aims to enhance the precision, reproducibility, and standardization of pathology-based researches, preclinical, and clinical trials through the sophisticated techniques it employs. The advent of whole slide imaging (WSI) technology is revolutionizing the pathology field by replacing glass slides as the primary method of pathology evaluation. Image processing technology that utilizes WSI is being implemented to automate and enhance analysis. Artificial intelligence (AI) algorithms are being developed to assist pathologic diagnosis and detection and segmentation of specific objects. Application of AI-based digital pathology in biomedical researches is classified into four areas: diagnosis and rapid peer review, quantification, prognosis prediction, and education. AI-based digital pathology can result in a higher accuracy rate for lesion diagnosis than using either a pathologist or AI alone. Combining AI with pathologists can enhance and standardize pathology-based investigations, reducing the time and cost required for pathologists to screen tissue slides for abnormalities. And AI-based digital pathology can identify and quantify structures in tissues. Lastly, it can help predict and monitor disease progression and response to therapy, contributing to personalized medicine.

The cytology of sputum specimens, at a medical facility in Korea, is using the liquid-based cytology and conventional smear method. It confirms the diagnosis using conventional smear methods and the liquid-based cytology. In addition, the diagnosis uses two kinds of each method, compares the suitability, sensitivity and specificity for each test and tries to understand the efficient method needed. It divided sputum specimens in half and liquid-based cytology. A conventional smear method was conducted and the Papanicolaou's staining was conducted using Autostainer. Diagnosed each slide of staining produced smear slides specimens by using an optical microscope. The result of the liquid-based cytology and conventional smear method was that the liquid-based cytology was of a higher-grade than the conventional smear method. It was 36.8%, and 62.8% in the same condition. But only one case was of a lower grade. Liquid-based cytology showed 86.2% of adequacy, 31.0% of sensitivity and 97.5% of specificity. The conventional smear method showed 54.4% of adequacy, 19.6% of sensitivity and 100% of specificity. If it was conducted with two methods at the same time, the results would be similar to the liquid-based cytology. In conclusion, liquid-based cytology has a more superior adequacy and sensitivity than the conventional smear method. The combination of the two methods is similar to the result of only conducting a liquid-based cytology. Conducting a liquid-based cytology rather than the combination of the two ways of sputum cytoscopy, is to be considered as an efficient method to achieve diagnostic accuracy, reduce labor of clinical technologist and pathologist, and to reduce the expense of patients.
