The Directional sign system in Korean high speed railway stations has a lot of problems. For an example, It lacks of consistency in the shape or allocation. Also, the signs do not match with the actual directions sometimes. Last but not least, the view is blocked by the other signs such as advertisement or other barriers. We suggested the methods to standardize the sign systems that include visibility, accuracy, consistency, and simplicity. First, we categorized signs into directional signs, locational signs, and informational signs. Then, we examined the actual high speed railway stations in Korea to learn the real situation. Finally, we suggested the methods to standardize the sign systems considering the factors that are visibility, accuracy, consistency, and simplicity.

현재 고속철도역의 안내표지판은 여러 가지 관점에서 많은 문제점이 있다. 일례로, 모든 고속철도역에서 모양이나 배치에 대한 통일성이 없다. 그리고 시설물의 안내 표시가 실제 위치와 전혀 다른 방향을 가리키는 표지판도 있다. 또한, 광고나 다른 장애물에 가려 보이지 않는 문제점이 있다. 이에 본 논문에서는 안내표지판의 시인성, 정확성, 통일성, 간결성의 특성을 포함하는 표준화 방안을 제시하였다. 제공하는 안내정보의 의미와 방법에 따라서 방향안내, 위치안내, 정보안내로 분류하였다. 분류한 유형에 따라 전국의 고속철도역을 조사하여 안내표지판의 특성을 분석하였다. 그리고 조사결과를 바탕으로 시인성, 정확성, 통일성, 간결성을 고려하여 우리나라에 적합한 안내표지판의 표준화 방안을 제시하였다.

A selected subject and a standardized scoring system were newly enforced at college entrance examination from 1999. A selected subject system means each student can select one subject in addition to common subject in the field of mathematical research II and a standardized scoring system means we standardize the score of each field as mean 50 and standard deviation 10 in order to adjust the degree of difficulty between fields. In the field of mathematical research II, there may exist not only difference of the degree of difficulty but also that of general studying ability between groups of selected subjects. So when we standardize score, we have to consider them. So far a linear equating which is a parametric method and an equi-percentile equating which is a nonparametric method have been published, but both of them supposed that the general studying ability between groups was equal. So in this paper an adjusted linear and percentile equating method which seems to be adequate to our entrance examination is suggested and is investigated by computer simulation.

This paper describes the development of standard series for turbo blowers. In mass production system, it is very required to standardize blowers to improve the productivity of ordering, estimating, manufacturing. To standardize blowers, we performed researches on the effects of $b_1$(impeller inlet width), $b_2$(impeller outlet width), ${\beta}_1$(blade inlet angle), ${\beta}_2$(blade outlet angle), Z(number of blades) of impellers and geometry of casing experimentally. Through this study, we chose the several best model of turbo blowers with high efficiency and low noise, which represent each specific speed series 63, 80, 100, 125, 160, 200, 250, 315. After the development of such standardized blowers, the test results are used to prepare the fan geometry and performance database for a selection software.

We need to make the standards of maintenance information for urban transit to reduce the cost to maintain the information and to share the information with maintenance workers. It is enable to do systematic maintenance for urban transit by using the information system based on the standardized information. In this paper we propose the major items to standardize and the methods to lay out the standard schemes to enable structured maintenance. We present the 4 items, bill of material, material classification, accident/fault classification, electronic document, to standardize. And we propose how to implement the information system for urban transit based on the standardized information. We describe the implemented information system in two parts; a rolling-stock and an infrastructure part. And also we describe the result of survey to evaluate the system installed at Seoul Metro and Seoul Metropolitan Rapid Transit.

The IEEE 1451.4 standards defines an architectural model for interfacing smart transducers for sensors & actuators. This standard allows analogue transducers to communicate their identification and calibration data in a digital format. A digital format is called the TEDS (transducer electronic data sheet). However, the standard template TEDS of IEEE 1451.4 do not supports sensors to use in electronic tongue system, such as arrayed-potentiometric and voltametric sensors. In this paper, a solution to standardize sensors for E-Tongue (electronic tongue) and electronic tongue systems is presented.

This paper suggests to standardize railway accident restoration types as the standardized code and to develop standard operation procedures(SOP) for the efficient railway accident management and recovery system. First of all, occurred damage types as the existing railway accident types in both domestic and foreign cases have been carefully analyzed and then reclassified. Therefore, this study suggested the combination of 3 distinct code factors: restoration class, restoration object, and restoration location to standardize them. In addition, temporary restoration SOP will play a major role in the railway accident batabase management system and SOP for the damage limitation and the prevention of accident spread.

The new information service has been demanded due to the recent mobile internet activation, and the government is promoting the activation of the private use of the public data by putting up the Government 3.0. According to government policy, many public sectors provide public data, but the railway sector is inferior to other public sector. In the case of national railway corporation, urban railway is now operated by 14 corporations such as Seoul Metro through the nation and high-speed railway is now operated by Korea Railroad Corporation and Supreme Railways. It is very difficult to standardize and integrate data due to mutual interests of national railway corporation. This paper describes a way to standardize and integrate rail passengers information collected through research project.

Immersive multimedia comprising metadata for five senses can provide user experience by stimulating memory and sensation. In the case of olfactory-enhanced multimedia, a computer-generated smell is combined with additional media content to create a richer and/or more realistic experience for the user. Although several studies have been conducted on olfactory-enhanced multimedia using e-nose and olfactory display, their practical applications have been severely restricted owing to the absence of a related standard. This paper proposes a method to standardize odor metadata obtained from an e-nose system, which has been particularly used to acquire data from different coffee aromas. Subsequently, the data were transferred to an odor display applicable for olfactory-enhanced multimedia using the ISO/IEC 23005 (MPEG-V) data template.
