  • Finding similar strings is an important operation because textual data can have errors, duplications, and inconsistencies by nature. Many algorithms have been developed for string approximate searches and most of them make use of inverted lists to find similar strings. These algorithms basically perform merge operations on inverted lists. In this paper, we develop a bitmap representation of an inverted list and propose an efficient search algorithm that can skip unnecessary inverted lists without searching using bitmap filters. Experimental results show that the proposed technique consistently improve the performance of the search.

  • The problem of semantic interoperability in science and technology information is frequently raised. Well-established classification scheme will be used as a tool to interchange information between different databases without semantic inconsistency. However, there is still a practical barrier due to different classification schemes each database adopts. Accordingly, it is urgent to harmonize or reconcile those classifications with each other. This paper aims to solve semantic inconsistencies occurred when interchanging information between databases having different classification schemes, the Standard National Sci-Tech Classification and the Standard KISTI Classification. For the purpose a conceptual analysis of science and technology are performed and five consistency/inconsistency types are analyzed based on some examples.

  • This paper investigated the rhythmic features of speakers of English as a lingua franca in Asian contexts. A speech corpus of 150 conversations between speakers of English in Asia with different L1 backgrounds was collected and %V, ${\Delta}V$, VarcoV, and nPVI-V of each speaker were analyzed. It was found that L1 difference of the speakers and the speakers' daily use of English influenced %V, while the speakers' daily use of English influenced ${\Delta}V$. The gender difference of the speakers also affected the rhythm of the utterances in VarcoV. A weak correlation between the two speakers' rhythm in each conversation was also found in %V and ${\Delta}V$. No significant effects were found in nPVI-V. The results revealed that the speakers tended to accommodate the rhythm of their utterance to that of the interlocutors'. Further study on the speaking rate of the speakers is required to overcome some inconsistencies found in the results of the rhythmic metrics used in this study.

  • Springback, an elastic material recovery after the unloading of stamping tools, causes variations and inconsistencies of final part dimensions. Recently, narrow and long surround molding parts around door frame are applied to high grade automobiles, but there are great difficulties in their die development, construction and tryout because of several springback modes including vertical movement and twist during flange forming process of them. So it is very important to predict springback's quantities of a surround molding part and, moreover, to compensate the die for them adequately, when they can't be corrected by the restrike operation. This paper presents a case study based on the die design for a surround molding part made of stainless steel. The forming and springback predictions, carried out using PAMSTAMP 2G, are reported and compared with the measurement data of the prototype. The predicted springback results were acceptable, so the processes of compensating die using Automatic Die Compensation Module of PAMSTAMP 2G were performed iteratively until the tolerances between the designed shape and the simulation data were satisfied.

  • Among the nutrients of biological importance, minerals are of particular interest in human nutrition because the range of adequate intake is so narrow. As the results of a series of interaction experiments between dietary fiber sources and minerals, there are many inconsistencies in the experimental data regarding the effect of dietary fibers on mineral bioavailability. the mechanism by which dietary fiber might influence mineral absorption is related to its physicochemical properties. These properties involve the ability of dietary fiber to (1) act as a weak cation exchanger, (2) decrease transit time, (3) dilute mineral concentration by increasing fecal bulk and (4) resist digestion in the large bowel. Regardless of the large number of human and animal studies available, a carful review of these publications dose not provide the answer as to whether the adverse effect of dietary fibers on mineral absorption is the fiber itself or some associated dietary factors( e.g. phytate, oxalate, ascorbate, citrate and protein, mineral-mineral interaction, etc) that are responsible for this action. As a result of the complexity of interaction that may take place between minerals. dietary fiber, and other component of food ; it becomes very difficult to blame fiber alone as a negative factor of mineral nutrition. We absolutely need more research with advanced tools rather than metabolic balance study.

  • This objective of this study is to examine the influence of age and gender on entrepreneurship in Vietnam's context. Although various studies have been conducted to examine age and gender differences in the entrepreneurial process, the results reveal inconsistencies. Moreover, the relationship between different factors and their role in explaining age and gender differences in the entrepreneurship activities still has no clear answer. Our analyses were based on data collected for the 2017 Global Entrepreneurship Monitors (GEM) from individuals located in Vietnam with a sample of 2,118. Our findings show that female entrepreneurs had less household income and were likely to have more fear of failure in starting a business. Entrepreneurs tend to be older and young entrepreneurs have better education. The study also indicated that male entrepreneurs were likely to have more perception of the ease to start a business. Moreover, the number of male respondents who are currently entrepreneurs is higher and they are older. The contribution of this study is twofold. First, it provides empirical evidence on the age and gender differences in entrepreneurship. Second, it contributes to the understanding of the entrepreneurship environment in Vietnam, one of the most dynamic emerging countries in the East Asian region.

  • Korean terminologies on flower structures of angiosperms in plant morphology, written incorrectly in many books, were analysed to suggest accurately expressed terminologies. 24 books in areas such as general biology, plant biology, plant morphology, and biological dictionaries and glossaries were selected to analyse the accuracy of the terminologies for seed structures, e.g., crassinucellate (ovule), tenuinucellate (ovule), placentation, free cental placentation, herkogamy or hercogamy, heterostyly or heterostylous, distyly or distylous, tristyly or tristylous, and hypanthium. The definition and etymology of the terminologies were traced in 4 textbooks of plant anatomy and 2 dictionaries of biology and botany written in English. On the basis of the definition, etymology, and principles for terminology formation according to the International Organization for Standardization (ISO 704:2000), accurately and reasonably expressed Korean terminologies were proposed. The 9 terminologies examined in this study were found in the glossary of biological terminologies, published by the Korean Association of Biological Sciences in 2005, and designated as an editorial source for science and biology textbooks for middle and high schools by Ministry of Education in 2007. However, none of the 9 terminologies described in the glossary were consistent with those proposed in the present study. The inconsistencies indicated the need for a reassessment of this glossary of biological terminologies. The new, proposed terminologies would facilitate mutual understanding between teachers and students of plant biology.

  • The inconsistencies between paralleled battery cells are becoming more considerable issue in high capacity battery applications like electric vehicles. Due to differences in state-of-charge (SOC) and internal resistance within individual cells in parallel, charging or discharging current is not appropriately balanced to each cell in terms of SOC, which may shorten the lifetime or sometimes cause safety issues. In this paper, an intelligent cell-balancing algorithm is proposed to overcome the inconsistency issue especially for paralleled battery cells. In this scheme, SOC information collected in the sub-BMS module is sent to the main-BMS module, where the number of parallel cells to be connected to DC bus is continuously updated based on the suggested SOC comparison rule. To verify the method, operation of the algorithm on 4 paralleled battery cells are simulated on Matlab/Simulink. The simulation result shows that the SOCs of paralleled cells are evenly redistributed. It is expected that the proposed algorithm provides high reliable and prolong the life cycle and working capacity of the battery pack.

  • Organizations rely on Secure ID resources today to handle vast amounts of information. Because the data can vary widely in type and in degree of sensitivity, employees need to be able to exercise flexibility in handling and protecting it. It would not be practical or cost-effective to require that all data be handled in the same manner or be subject to the same protection requirements. Without some degree of standardization, however inconsistencies can develop at introduce risks. Policy formulation is an important step toward standardization of security activities for ID resources. ID security policy is generally formulated from the input of many members of an organization, including security officials, line managers, and ID resource specialists. However, policy is ultimately approved and issued by the organization's senior management. In environments where employees feel inundated with policies, directives, guidelines and procedures, an ID security policy should be introduced in a manner that ensures that management's unqualified support is clear. The organization's policy is management's vehicle for emphasizing the commitment to ID security and making clear the expectations for employee involvement and accountability. This paper will discuss ID security Policy in terms of the different types (program-level and issue-specific), components, and Implementation of Expert System Simulation based on 4GL, PowerBuilder.
