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 estimates are the numerical data of a unit quantity required for construction work such as the amount of materials, manpower, and the use of equipment required and are also a basis to calculate construction costs. Unfortunately, standard estimates for construction have also been used for garden construction these days as no standard estimates for garden construction have been developed or documented until now. As a result, many problems have arisen at garden construction sites since landscape construction and garden construction differ in terms of scope, size, design and construction methods. The purpose of this study was to develop standard estimates for garden construction for proper calculation of the cost of garden construction and to ensure gardens are created following appropriate construction processes. In order to develop standard estimates for garden construction, a preliminary survey was conducted on experts to understand current issues at first. After that, a questionnaire survey was done to examine problems of construction processes and ways of improvement, and on-site inspections were conducted utilizing CCTVs at construction sites to identify the actual amount of manpower required on site. Based on the results of the surveys and on-site inspections, a draft version of standard estimates for 5 types of planting work for garden construction was developed. Developing standard estimates for garden construction will serve as a stepping stone for the transparent and proper compensation for garden construction work, which will not only contribute to addressing issues between consumers and construction companies, but also to the stabilization of market economy and job creation.

Although the number of registered cars in South Korea is about 22million but, there is no national standard for automobile reference fuel in South Korea. Reference fuel is the fuel used for certificating vehicle performance, emissions and fuel economy. Now, domestic market fuels are used as reference fuel. However, the quality of domestic market fuel is constantly changing by seasonal and fuel manufacturers. It may effect vehicle performance, emissions and fuel efficiency test result. On this study, market diesel fuel quality was monitored and reference fuel standard(draft) was set by reflecting market fuel monitoring result. Reference fuel standard(draft) was applied to CRDI engine.

Science education researchers have discussed more effective STPD(Science Teacher Professional Development) based on a variety of perspectives, pointing out the limitations of traditional STPD. In this study, we selected eight major issues for more efficient STPD based on the literature review, summarized the literature review contents for each issue, and proposed a draft STPD standard based on the literature review. Using the draft STPD standard, a questionnaire for the Delphi survey was developed and a two-phase Delphi survey was conducted. The questionnaire consisted of 25 statements describing the STPD standard, and respondents were asked to indicate the validity and importance of the statement on a Likert scale, followed by an explanation and suggestions for revision. Twenty-one science educators and science teachers participated in the Delphi survey, and the results of the second round of the survey showed high levels of agreement on the validity and importance of all statements describing the STPD standard. For the content validity ratio and coefficient of variation, all statements met the criteria, and for the convergence and consensus, all but two statements met the criteria. Two statements were revised to reflect comments from the Delphi survey and were included in the final STPD standard. As a result, we developed STPD standard consisting of 23 statements in eight categories, and we discussed the disadvantages and advantages of the developed STPD standard and how to utilize them, as well as suggestions for future improvement and research.

The content of this paper is concerned with guard band and technical standard for wireless local loop facilities will be used at 260Hz domestic frequency band. In order to determine guard band between wireless local loop providers, this paper analyze radio interferences from radio station used adjacent frequency band. The paper proposes draft Out-of-Block Emission Mask of for wireless focal loop facilities in accordance with ITU-R Recommendation and ARIB Standard in Japan
