  • American Society for Testing and Materials (ASTM) standard test method PS 070-97 has been created for measuring fracture toughness of advanced ceramics. PS 070-97 includes three test methods which use beams in bending: chevron notch (CNB), single-edged precracked beam (SEPB), and surface crack in flexure (SCF). Supporting data has been collected through several Versailles Advanced Materials and Standards round robins. This paper discusses the evolution of the standard including the rationale for the choice of the three methods and the specifications in the standard. Progress on Standard Reference material 2100 which will have certified values of fracture toughness is presented.

  • RI-Biomics is a new concept that combines radioisotopes (RI) and Biomics. For efficient collection of information, establishment of database for technical information system and its application to the system, there is an increasing need for constructing the standard classification system of technical information by its systematical classification. In this paper, we have summarized the development process of the standard classification system of technical information in the field of RI-Biomics and its application to the system. Constructing the draft version for the standard classification system of technical information was based on that standard classification one in national science and technology in Korea. The final classification system was then derived through the reconstruction and the feedback process based on the consultation from the 7 experts. These results were applied to the database of technical information system after transforming as standard code. Thus, the standard classification system were composed of 5 large classifications and 20 small classifications, and those classification are expected to establish the foundation of information system by achieving the circular structure of collection-analysis-application of information.

  • Standard lots, which are used to assess values of individual lots in Korea, have been criticized for their improper distribution. However, there has been very little evaluation for the spatial distribution of standard lots, and an evaluation method has never been developed. In order to overcome this situation, we attempt to assess the appropriateness of the spatial distribution of standard lots using the L-index and Monte Carlo simulation. The L-index is a well-known indicator of the complete spatial randomness (CSR) of points in spatial statistics. If the L-index of standard lots is similar to that of individual lots, the former is considered to be randomly distributed according to the latter. By analyzing L-indices of two study areas, Gangnam and Seongdong, we find a statistically significant difference in Gangnam area and a relatively small difference in Seongdong area. We confirm that the spatial distribution of standard lots is not CSR and that the L-index is useful as an evaluation method. These results suggest that the standard lot selection and management guidelines need to be modified to apply the spatial distribution of individual lots to the standard lot selection process.

  • Purpose. This research is implemented to identify the status of educations about the pricing standard, status of the cognition of the pricing standard, and the solutions to the questions on the pricing standard of the oral health professionals. it will provide the easier accessibility to the annual changes in Dental Health Insurance Standards to the oral health professionals. Methods. The research subjects are the total 204 oral health professionals in limited area, and it was analyzed with structured questionnaires. The collected data is analyzed by IBM SPSS ver. 19.0, a statistical program (IBM Co., Armonk, NY, USA) for the frequency and percentage, and ANOVA. The result is as following Results. The awareness of dental health insurance standard was statistically significant differences by age (p<0.01), career (p<0.001), the prime task (p<0.01), and dental insurance claimants (p<0.05). The awareness of the standard was statistically significant differences by educational training within last 6 months (p<0.05), the cognition of the standard (p<0.001), and solutions for the questions (p<0.05). Conclusions. As the results of the research, it is necessary to develop the educational program under condition of age, career, main task, and better understanding in Dental Health Insurance Standard for oral health professional.

  • The Rural Housing Standard Plans for improving the quality of life and housing stability in rural areas has been developed 87 types from 1994 to 2012. However, some types of Plans do not satisfy the current legal standard in accordance with social and legal changes. Standard plans has the same effect as a building permit, and replace it, so legal suitability of Plans is an important. Therefore, it is required the suitability analysis on the legal standards of Rural Housing Standard Plans. The Purpose of this study is to derive improper types and items of the Rural Housing Standard Plans on the legal standards. In this study, we analyzed its suitability on the legal standards(law on fire-fighting system installation and safety management, energy saving design criteria for buildings, structural checklist for small buildings, the types of drawing for building permit) in accordance with "rules for the operation of standard plans". And we analyzed the utilization of the Rural Housing Standard Plans through downloads from welchon portal.

  • Recently, the comparative gap of technology and product has been decreased in the global market, and the globalization has been extended rapidly. Industries try to get de facto standard as the global standard. De facto standard has become a standard not because it has been approved by a standards organization but because it is widely used and recognized by the industry as being standard. Advanced countries already have their own organizations under the government, and they cooperate tightly with companies. As a result, we also try to have the organization and build the good relationship between companies and the government to get de facto standard in the global market.

  • Purpose: The purpose of this study was to investigate nursing students' awareness and performance on standard precautions and to provide meaningful information for nursing students' education regarding hospital infection control. Method: Four hundred forty seven nursing students at 6 universities in D-city participated in this study. Data collection was conducted from March to April 2011. Students' awareness and performance on standard precautions of infection control in hospitals were measured using the modified 2007 CDC standard precautions guidelines. Data analysis was performed using the SPSS WIN 18.0 program, descriptive statistics, t-test, and ANOVA. Results: The level of students' awareness in the standard precautions was higher than performance. The higher levels of students' awareness and performance on standard precautions included patient care equipment, safe injection practices, and worker safety. The lower levels of students' awareness and performance on standard precautions included hand hygiene and personal protective equipment. There was no difference in the students' awareness and performance of standard precautions according to their characteristics. Conclusions: Based on the findings of this study, hand hygiene and personal protective equipment need to be stressed more within the program to improve nursing students' infection control techniques.
