There are two basic concepts in industrial radiographic examination; one is a radio-graphic sensitivity, and the other is a acceptance criteria. The comparison of these main points are studied for KS Standard and ASME Boiler and Pressure Vessel Code. From the results of the experiment, higher radiographic sensitivity is required in KS Standard when the thickness of material to be examined is less than 20mm in single wall technique. The acceptance criteria for linear type indications are described on same concept in two standards, whereas the acceptance criteria for rounded indications of KS Standard which mainly depends upon the object thickness are more severe than those of ASME BPV Code.

Since 1990s, we have achieved a certain level of success in standardization of design, construction, and material on housing and public buildings with the national-level promotion. A practical connecting device that can synthesize all the serial processes is required to maximize the effect of construction material standardization. However, desired outcome of the standardization is not achieved yet because these serial standards and notification practices are decided by each part of the process and some are congested. In this study, we aim to improve a general organizational system of Korean Industrial Standard (KS) which is the most fundamental tool for the standardization of construction materials moving from a conventional idea that the standard is only for the material and components producers to a concept that can also be shared by the designers and construction workers. To achieve this, we propose an improvement plan for the Korean Industrial Standard in the perspective of three-tier classification system.

Pneumatic servo valve which is widely applied in industrial world is advanced technology compounded with electric, electronic and machine. And It is consist of Linear Force Motor. Spool Commutation Mechanism and Microprocessor. In this study, we accomplished test method of Linear Force motor test, Static characteristic test, Dynamic characteristic test for KS(Koran industrial standard) of Pneumatic servo valve. we accomplished study about the main item of Static characteristic test which is related to unload flow characteristic test. And Dynamic characteristic test was step input test and frequency response test. Specially about frequency response test, There was a difficulty resulting from the time delay problem caused by the basic compressibility of air. In order to solve the problem in this study. we proposed two methods. First, displacement of the servo valve spool was directly measured by using a laser sensor. Second, method of calculating control flow by measuring pressure and temperature of chamber.

In this study, two things were analyzed for Korean Standards certification factory review evaluation items. First, it was examined whether there is a difference between the Practice of factory review evaluation items and Post-Management according to the change in perception of the factory review evaluation items of Korean Standards certification personnel. Second, the moderating effect of the Korean Standards certification personnel's perception of the effect of the Practice of the factory review evaluation items of Korean Standards certification personnel on Post-Management was verified. Although there is a statistically significant difference between Practice and Post-Management according to changes in perception of Korean Standards personnel, there is no statistically significant difference in the impact (slope) of Practice on Post-Management according to changes in perception of Korean Standards certification personnel. As the perception of factory review evaluation items increases, the Practice and Post-Management of factory review evaluation items are increasing, but the impact of the Practice of factory review evaluation items on Post-Management does not affect it. In order to further advance Korean Standards certification, which plays an important role in maintaining the quality level of products produced by companies, efforts to raise the level of perception of Korean Standards certification personnel are considered necessary.

The wind turbine, Europe and the United States are different with the standards process each other when the manufacturing company which in order to demand the standards process to a construction in the multi country with interested parties of the corresponding nation to, always the re-agreement is difficult. Korean wind turbine also detail there is not a standard, when it produces and establishes of wind turbine, the problem point occurs. It is like that investigation of international standards system it leads and when it prepares the Acoustic noise measurement of the Wind Turbine Systems of Korea, it prepares the base for industrial development wind turbine of Korea.

New and Renewable Energy Equipment Certification program has been integrated into the KS(Korean Industrial Standards) certification system as of July 29, 2015. This study is to determine whether the KS certification requirement has had a positive effect on corporate performance (e.g. quality improvement, financial result, customer satisfaction) within those that had already acquired the New and Renewable Energy Equipment KS certification. As a result, among the requirements for the KS certification, quality management, product management, and product testing have a positive impact on product quality improvement, and product testing has shown a positive influence on customer satisfaction. Although requisite for the KS certification did not have a significant effect on financial outcome such as increase in revenue, it has shown to have positive consequence to some extent on those firms that newly obtained the certification.

In many companies handling flammable liquids, explosion-proof electrical equipment have been installed according to the Korean Industrial Standards (KS C IEC 60079-10-1). In these standards, hazardous area for explosive gas atmospheres has to be classified by the evaluation of the evaporation rate of flammable liquid leakage. The evaporation rate is an important factor to determine the zones classification and hazardous area distance. However, there is no systematic method or rule for the estimation of evaporation rate in these standards and the first principle equations of a evaporation rate are very difficult. Thus, it is really hard for industrial workplaces to employ these equations. Thus, this problem can trigger inaccurate results for evaluating evaporation range. In this study, empirical models for estimating an evaporation rate of flammable liquid have been developed to tackle this problem. Throughout the sensitivity analysis of the first principle equations, it can be found that main factors for the evaporation rate are wind speed and temperature and empirical models have to be nonlinear. Polynomial regression is employed to build empirical models. Methanol, benzene, para-xylene and toluene are selected as case studies to verify the accuracy of empirical models.

본 연구는 변전소(사무실) 비상 및 복구등 설비환경 개선차원으로 실시하였다. 기존 비상등의 낮은 조도로 인해 발생하는 문제점을 해결하기 위해 AC/DC 겸용 형광등 안정기 및 스위치를 연구하였다. 또한 조도기준을 상시등의 5~10[%]가 아닌 한국산업규격 조도기준(KS A 3011)에 따른 원자력발전소 조도기준과 안전조명 조도기준을 참고로 변전소 각 실별 조도기준을 제안하였다. 마지막으로 본 연구에서 제안한 내용의 타당성을 검토하기 위해 실험을 하였다. 그 결과 축전지 용량을 증가시키지 않으면서도 비상 및 복구등의 조도를 높일 수 있었다.
