  • There are lack of labour and increase in logistics costs due to rapid change in logistics environments and the demand for logistics. The reality is that over spending on logistics costs are getting worse due to lack of logistics standardization. An example will be excessive logistics costs caused by unsatisfactory use of logistics equipments in wholesale markets. The logistics efficiency is falling due to delays in using logistics equipments and standardization. Therefore, there needs standardization of logistics functions and unit of handling in each stage from packing, unloading, storage, transporting, logistics information and needs logistics standardization on equipments, machineries used for the above. Standard unified with standardization is called specification and if standardization is applied broadly in manufacturing or processing, inspection than each process in terms of production can be managed rationally and labour skills will improve and product quality will be evenly maintained and compatability of each part in terms of assembly will be maintained thus materials and labour could be saved thus results in increasing productivity and lowering production costs. Also, if it is applied in industry at state-level then there will be rationalization in consumption in circulation as in purchase of raw materials, sales of products, purchase of products by consumers and contribute in improving compatibility and fair transactions. This paper is aimed to help in first solving factors affecting the most in improving logistic efficiency among unit load system and logistic hollowization, standardizing logistics base, standardizing logistics information. The study conducted surveys on limited companies but hope that in the future the target companies can be divided further into types, industries and conduct more demonstrative analysis.

  • Existing research on international standardization has largely taken a qualitative approach focusing on comparative studies of national institutions and policies on standards or international rivalries from the perspectives of international relations or innovation studies. While there exists a handful of quantitative studies, they are mostly confined to simple numeric counts of essential patents, new work item proposals, or secretaries staffing international standards development organizations (SDOs). This study aims to contribute to our understanding of the dynamics of international standardization by the analysis of the data coding systematically national activities in the standardization process of the International Organization for Standardization (ISO), by far the largest international SDO. Our analysis of the four critical types of standardization documents generated in the Working Group 7 of the ISO/IEC Joint Technical Committee 1 reveals interesting dynamics among key players of global ICT standards regime. First, while the US takes a dominant share of the personnel as well as new work item proposals for standardization, its quality of activities rather falls behind as it mostly focuses on keeping in check other countries' standardization activities. Second, European countries tend to spread their effort evenly across different types of standardization activities. Finally, despite such differences between the US and European countries, both rely heavily on multinational companies to gain an advantage in the voting stage of standardization process.

  • With the rapid progress of the aging society in Korea, the silver generation is emerging as another class of users in the new population structure. This is a social issue to be dealt with, and the effect of such a change is being observed dearly in the design area. In addition, there are increasing demands for consideration of minor groups of users including the elderly, the disabled, the left-handed, children and pregnant women and nursing mothers, who have been treated as the weak. Such a human-centered idea may be the manifestation of the recovery of humanity and the self-realization of human beings through experiences and reflections of the industrial society of the past. The present study examined the tendency of design standardization centering on universal design, which has emerged in response to user-centered social needs, and suggested general considerations for the necessity of introducing such standards. These days the meanings of standardization are not limited to quality, performance, safety and economic aspect. Standardization is required to consider the diversity and the welfare of human beings. In addition, one of the important functions of standardization is to provide designers with important clues and guidelines for designing. In reality, however, standardization has been rejected by the circle of design for the reason that it deters free creation, so research on the introduction of standardization has been at standstill. As ISO/IEC Guide71 was published in November 2001, based on which, the Korea Standards Association established KS A ISO/IEC Guide71 without changing its contents. In companies' manufacturing activities, the progress of standardization in connection to universal design is growing more important. However, usefulness and interchangeability for the absolute majority resulting from standardization are incomparable. Lastly, the realization of universal design requires human-centered design mind, based on users' experiences and needs, the characteristics of the human bodies and inconvenient elements rather than standards for the sake of standardization.

  • As the broadband network are being deployed recently, the IPTV (Internet Protocol TV) has appeared and become a most representative service that incorporates audio, video, etc. In spite of the long-period efforts, however, no standardized method exists to measure and evaluate the quality of video that is experienced through TV in the customer's premises. Therefore, before developing a method to measure and evaluate the quality of experience (QoE) for video that is the ultimate goal, this paper reviews the outcomes from the past standardization activities and drive a few important implications that would be reflected to the method to measure and evaluate QoE for video.

  • Standardization is a prerequisite of quality control in any field. Library field is not an exception. The bibliographic control structures of AACR2R, MARC, DDC, LCC, LCSH, ISBD are highly standardized and dependent on rigorous authority work, so that libraries and bibliographic utilities using these tools could provide effective quality services. In order to emphasize the importance of standardization in the field of bibliographic control structures, this study focuses on inconsistencies in transliterated foreign personal and geographic names in headings, used as the caption of a given class as well as in notes describing what is found in a class or clarifying the notation hierarchy in the 4th edition of KDC. This study also examines Korean transliteration of loan words in the schedule as well as the transliterated entries of the Relative Index.
