Standards are essential to facilitate the efficient use of GIS data. International Standards such as ISO TC211's 19100 series and various technical specifications from OpenGIS Consortium are some of the examples of efforts to maintain the interoperability among GIS applications. This paper aims to provide the effective policy directions that can increase the use of GIS standards by providing the comprehensive list of priorities in developing GIS standards. This paper reviews the current status of the use of GIS standards in the field and analyses the use pattern. Also this paper examines the need for revision of the existing standards and new standardization efforts based on the current status of International Standards. Based on the analysis of the use pattern of the current GIS standard, this paper suggests a policy directions which emphasizes the need for more efforts in standardization of geographic information services standards and more coordination among all standard-related stakeholders in government and industry.

As international standards of ICT were recently recognized as a essential strategy to penetrate into global markets in advance, the competition for international standardization among advanced countries and companies has been intensified. Meanwhile, our country has become the first one in the world market share of display devices since the year 2001. Due to world economic depression, the industry of display has become stagnant since the year 2010. Therefore, advance countries have concentrated on the research and development of next-generation display to overcome this situation. It is necessary to set up the strategy of standardization on essential technology of next-generation display and implement it systematically in order to take leading position in global market of next-generation display in smart information society of the 21th century. In this paper, I'll propose constructive strategies of standardization through analyzing the trend and environment of standardization and technological development of next-generation display.

According to the rapid development of IT technologies, between different technologies and weakness of entry barriers, standardization for interoperability and intercompatibility is being recognized as a core strategy for preoccupation of global IT market and strengthening of national competitive power. Recently IPR(Intellectual property Rights) including patents is considered indispensably in international standardization. Also advanced countries strengthen their positions through preemption of global IT market by linking their IPR with international standardization. Therefore relationship between IPR and standardization is being changed to mutually complementary from mutually exclusive. In this paper, we will examine ITU-T's IPR policy and related discussion trends in ITU-T and try to find national policy for IPR related issues.

This study was conducted on the assumption that for Incheon international airport to become the logistics hub of northeast asia's region, it is necessary to investigate and analyze problems of forwarder's international air cargo transportation process, those factors and so on. The conditions of the process of international air cargo transportation was analysed individually according to the time required, satisfaction and problems of each step of process by dividing those into import and export. Consequently it turned out that the time required for the export process of the international air cargo transportation is longer by about 1 hour than the import process which means the improvement of import section rather than export is more urgent to improve the overall international air cargo transportation process. For the improvement of the process, it is also necessary to construct the international air cargo transportation' information system, secure competition of operating and to improve logistics standardization by considering all factors above.

PURPOSES: In this paper, the effectiveness of speed-maintained standardization in road geometry on environmental impact at a downward slope location, based on greenhouse gas (GHG) emission indicators, was studied. Specifically, the aim of this study was to ascertain whether speed-maintained standardization resulted in decreased $CO_2$ emissions as well as noise pollution, due to reduced vehicle speeds. METHODS : In this study, speed-maintained standardization in road geometry was proposed as a means to reduce vehicle speeds, with a view to reducing $CO_2$ emissions and noise pollution. This technique was applied at a downward slope location. The vehicle speeds, $CO_2$ emissions, and noise levels before and after application of speed-maintained standardization were compared. RESULTS: It was found that speed-maintained standardization was effective as a means to reduce speed, as well as $CO_2$ emissions and noise pollution. By applying speed-maintained standardization, it was confirmed that vehicle speeds were reduced consistently. As a result, $CO_2$ emissions and noise levels were decreased by 9% and 11%, respectively. CONCLUSIONS : This study confirmed that speed-maintained standardization in road geometry is effective in reducing vehicle speeds, $CO_2$ emissions, and noise levels. Moreover, there is further scope for the application of this method in the design of roads in urban and rural areas, as well as in the design of highways.

A previous study (Berzaghi et al., 2001) evaluated the performance of 3 calibration methods, modified partial least squares (MPLS), local PLS (LOCAL) and artificial neural networks (ANN) on the prediction of the chemical composition of forages, using a large NIR database. The study used forage samples (n=25,977) from Australia, Europe (Belgium, Germany, Italy and Sweden) and North America (Canada and U.S.A) with reference values for moisture, crude protein and neutral detergent fibre content. The spectra of the samples were collected using 10 different Foss NIR Systems instruments, only some of which had been standardized to one master instrument. The aim of the present study was to evaluate the behaviour of these different calibration methods when predicting the same samples measured on different instruments. Twenty-two sealed samples of different kind of forages were measured in duplicate on seven instruments (one master and six slaves). Three sets of near infrared spectra (1100 to 2500nm) were created. The first set consisted of the spectra in their original form (unstandardized); the second set was created using a single sample standardization (Clone1); the third was created using a multiple sample procedure (Clone6). WinISI software (Infrasoft International Inc., Port Mathilda, PA, USA) was used to perform both types of standardization, Clone1 is just a photometric offset between a “master” instrument and the “slave” instrument. Clone6 modifies both the X-axis through a wavelength adjustment and the Y-axis through a simple regression wavelength by wavelength. The Clone1 procedure used one sample spectrally close to the centre of the population. The six samples used in Clone 6 were selected to cover the range of spectral variation in the sample set. The remaining fifteen samples were used to evaluate the performances of the different models. The predicted values for dry matter, protein and neutral detergent fibre from the master Instrument were considered as “reference Y values” when computing the statistics RMSEP, SEPC, R, Bias, Slope, mean GH (global Mahalanobis distance) and mean NH (neighbourhood Mahalanobis distance) for the 6 slave instruments. From the results we conclude that i) all the calibration techniques gave satisfactory results after standardization. Without standardization the predicted data from the slaves would have required slope and bias correction to produce acceptable statistics. ii) Standardization reduced the errors for all calibration methods and parameters tested, reducing not only systematic biases but also random errors. iii) Standardization removed slope effects that were significantly different from 1.0 in most of the cases. iv) Clone1 and Clone6 gave similar results except for NDF where Clone6 gave better RMSEP values than Clone1. v) GH and NH were reduced by half even with very large data sets including unstandardized spectra.

From the 20th century, as international trade increases with the development of transportation and industries, a standard pictorial language to facilitate exchanges with others in different countries became necessary. However, it is not easy to have a full agreement on a standard pictorial language among different cultures. Therefore, the evaluation of standard pictograms has been the main discussion issue of the 150 since the organization's establishment in 1947. Although the 150 has a test method, 1509186, the participating countries do not follow the test because it does not reflect individual seeing mechanism for decoding pictogram which varies with his/her own experience. This study focuses on the theory of graphic symbol and seeing mechanism, and suggests what should be taken into account in the standardization process. In Chapter 2, the study investigates whether there be any cultural shock as we live in the net culture, and defines what reality is from a digital aesthetics view. What should be studied further is also presented, and a new method for revised international standard by means of analyzing seeing mechanism of decoding pictogram is suggested.
