Purpose: The Korean government has implemented a Barrier Free Certification System since 2008 to create a secure and convenient environment for the socially disadvantaged. The drastic increase in the number of BF-certification facilities is expected due to the revision of the system and increasing the number of certification institutions. An analysis of individual evaluation items needs to be made for the BF-Certification with public confidence. Method: Korean standard, International Standard(ISO/FDIS 21542, 2011), German Standard(DIN 18040-1, 2010), Austrian Standard(${\ddot{O}}NORM$ B 1600, 2017) and Swiss Standard(Norm SIA 500 / SN 521 500, 2009) were investigated and analyzed. A comprehensive improvement plan is proposed by comparing details of the aforementioned standards and the evaluation items of BF-Certification. Results: Many problems arise in applying existing Barrier-free standards due to changes in population structure, environmental change and the use of powered wheelchairs. International standards are being improved to solve these problems. The korean standards also require improving of the Barrier Free Law and Certification System, which reflect these trends. In korean cases, standards such as the size of the doors (width and height), the Unobstructed Manoeuvring Space and Clear Space at the Latch side of the Door are required to improve standards in accordance with international standards. In addition, the expression of laws and evaluation items of BF-Certification should be clearly defined. And the application of visual contrast standards for the enhancement of perceptions presented in international standards should be considered. Implication: Barrier Free related legal standards and evaluation items of BF-Certification that are used in Korea are required to be revised in consideration of social and environmental changes. Comprehensive improvements should be made through detailed review.

Kimono sleeves have continuously appeared in modern fashion as a design motif and this trend has become increasingly prevalent recently. However for research in the area of clothing composition for kimono sleeves in Korea, there has been a lack of development of master patterns based on basic data from the analysis of the standard body type of Korean people and finalized designs based on comparative experiments and analysis of pre-existing research Thus, there is no ideal master kimono sleeve pattern development research based on the examination of the results of the analysis of the standard body type of Korean people. Therefore by recognizing the importance of developing a master kimono sleeve pattern, this research aims to present a practical master kimono sleeve pattern for the standard body type of someone in their 30s. First, the four master patterns were collected and a dressing evaluation was conducted, and by selecting and improving one of these master designs, a final research master pattern was developed after a second dressing evaluation. Through this research, it was possible to design a master kimono sleeve pattern appropriate both externally and functionally for the standard body type of someone in their 30s, which has not been a consideration in previous research.

Evaluation of long term stability of the Brinell standard hardness tester was carried out to secure its application as a national standard in Brinell hardness. Accuracy and repeatability in load application were tested through evaluating errors in hardness measurement of certified reference blocks. All of those requirements in KS as well as ISO specifications were satisfied by this standard hardness tester. In addition to this, long term stability test of automatic indentation measurement system was carried out. The scattering range was almost the same with its error range. To figure out an optimum test condition for better repeatability and long term stability, the effect of load variation, load application speed and time have been studied using orthogonal array experimental plan. It was found that the best combination is $30{\mu}m/s$ of load application speed and 25 seconds of load application time.

Currently, the United States, the United Kingdom, Australia etc. are actively utilizing energy simulation for efficiency evaluation of building energy. However, domestic energy efficiency assessment system doesn't use energy simulation system properly at present: parameters based architecture plans and Ashrae Standard are inputted for the evaluation, because the input parameters for the simulation haven't been established yet. This fact causes poor reliability during energy simulation, as the values of the two standards are different from each other. Therefore, the aim of the study is to set domestic standard parameter for BIM-based energy performance evaluation, focusing on possession area per person of occupants at government office in Korea. We found that the difference among the result values occurred approximately 3% in the energy simulation. As a result of the analysis, possession area per person of occupants in Government office is $31.87m^2$. Other input parameters may be set based on this. This will increase the reliability of energy simulation through a domestic standard parameter.
