  • Methods of the characteristics evaluation of turbo-molecular pumps (TMP) are well-defined in the international measurement standards such as ISO, PNEUROP, DIN, JIS, and AVS. The Vacuum Center in the Korea Research Institute of Standards and Science has recently designed, constructed, and established the integrated characteristics evaluation system of TMPs based on the international documents by continuously pursuing and acquiring the reliable international credibility through measurement perfection. The measurement of TMP pumping speed is normally performed with the throughput and orifice methods dependent on the mass flow regions. However, in the UHV range of the molecular flow region, the high uncertainties of the gauges, mass flow rates, and conductance are too critical to precisely accumulate reliable data. With UHV gauges of uncertainties less than 15% and a calculated conductance of the orifice, about 35% of pumping speed uncertainties are experimentally derived in the pressure range of less than $10^{-6}$ mbar. In order to solve the uncertainty problems of pumping speeds in the UHV range, we introduced an SRG with 1% accuracy and a constant volume flow meter (CVFM) to measure the finite mass flow rates down to $10^{-3}$ mbar-L/s with 3% uncertainty for the throughput method. In this way we have performed the measurement of pumping speed down to less than $10^{-6}$ mbar with an uncertainty of 6% for a 1000 L/s TMP. In this article we suggest that the CVFM has an ability to measure the conductance of the orifice experimentally with flowing the known mass through the orifice chambers, so that we may overcome the discontinuity problem encountering during introducing two measurement methods in one pumping speed evaluation sequence.

  • Background : Efforts towards increasing insurance coverage for traditional Korean medicine (TKM) are being continued. However, various difficulties are faced in generating evidence for TKM due to limited financial support and the low quality of research methodology. Objectives : The objectives of this study were to review the Swiss evaluation program for complementary and alternative medicine (CAM) and assess the expansion in public health insurance coverage of complementary medicine as approved by referendum in Switzerland. Methods : The regulations of CAM in the European Union were assessed. Research articles, reports, government publications and websites which deal with the 'Programm Evaluation $Komplement{\ddot{a}}rmedizin$ (PEK)' and the referendum in Switzerland were searched for and analyzed. Results : The PEK was conducted from 1998 to 2005. The PEK evaluated the efficacy, utilization and cost-effectiveness of anthroposophical medicine, homeopathy, neural therapy, phytotherapy and traditional Chinese medicine. However, clear conclusions could not be drawn from the evaluation according to the PEK Report. Later, a referendum was implemented in which 5 therapies would be added to the Switzerland Constitution with the support of the public. The coverage of CAM was approved by Swiss a plebiscite with an approval rate of 67.0%. Conclusions : The reason for the successful referendum is suggested to be public support and the solidarity with CAM experts and politicians. It may be surmised that recognition of the political efforts and scientific aspects required to expand insurance coverage of TKM, and towards obtaining public support, is necessary.

  • A model system has been established for the evaluation of the uncertainty of the value from measurements of multiple subsamples by isotope dilution mass spectrometry (IDMS). In this report, we apply this model system for the evaluation of measurement uncertainty in determination of folic acid in infant formula. Five subsamples were analyzed by IDMS. The mean of the measurement results of the five subsamples was assigned as the final measurement value. The standard deviation (s) of the results from five subsamples was attributable to repeatability of the measurement. The uncertainty components in the IDMS measurement methods were categorized into two groups. Group I includes uncertainty components which give common systematic effects to all subsamples and do not contribute to the variation among multiple measurements (repeatability). Group II includes uncertainty components that give random effects on the measurement results, and are related with the measurement repeatability. These random effects are attributed to s. Therefore, the uncertainty of the final value was calculated by combining the standard deviation of the mean of multiple measurements, $s/{\surd}n$ (where n = 5), and the measurement uncertainty associated with the uncertainty components that give systematic effects.

  • This study proposes a new methodology to increase the flexibility and efficiency of the design data evaluation system by combining Building Information Modeling (BIM) technology in the architectural industry, OpenAI's interactive artificial intelligence, and ChatGPT. BIM technology plays an important role in digitally modeling and managing architectural information. Since architectural information is included, research and development are underway to review and evaluate BIM data according to conditions through program development. However, in the process of reviewing BIM design data, if the review criteria or evaluation criteria according to design change occur frequently, it is necessary to update the program anew. In order for designers or reviewers to apply the changed criteria, requesting a program developer will delay time. This problem was studied by using ChatGPT to modify and update the design data evaluation program code in real time. In this study, it is aimed to improve the changing standards and accuracy by enabling programming non-professionals to change the design regulations and calculation standards of the BIM evaluation program system using ChatGPT. In this study, in the BIM-based design certification automation evaluation program, a program in which the automation evaluation method is being studied based on the design certification evaluation manual was first used. In the design certification automation evaluation program, the programming non-majors checked the automation evaluation code by linking ChatGPT, and the changed calculation criteria were created and modified interactively. As a result of the evaluation, the change in the calculation standard was explained to ChatGPT and the applied result was confirmed.

  • This study intends to examine the indicators of Korean medicine education that are directly required in the field, in the process of developing and rationalizing the second cycle of evaluation and accreditation standards for the Colleges of Korean medicine and present indicators to the Korean medicine education community. To this end, we conducted the Delphi survey on six Korean medicine education experts, and the second cycle evaluation and accreditation standards were developed after verifying the validity of the contents and through a public hearing on three experts. Based on the research results of this study, we make the following suggestions: First, the support of Korean medical education institutions should be considered. The Korean medical education institution operates the Korean medicine hospital under each institution's name. Thus, criteria for evaluation shall be considered according to the number of beds and the support of schools. Second, for the second cycle of evaluation, all six members of the evaluation committee were professors of Korean medicine; however, in the future, each group of the evaluation committee needs to be composed of an external curriculum and evaluation experts to seek the evaluation focusing on education. Third, it is necessary to include curriculum and evaluation experts in the development stage of education programs and institutional evaluation and accreditation standards. Fourth, the experts of the curriculum should be included as the members of the curriculum development team of the College of Korean Medicine. This study is meaningful as a study to improve the quality of Korean medicine education.

  • This study aimed to evaluate the applicability of "food and nutrition standards for child care setting in the Seoul Metropolitan Government" using quantitative and qualitative surveys and lay the groundwork for future expansion. To evaluate the understanding and applicability of each item of the standards and utilize goodness of fit as an evaluation item to improve practicality of the child care center's health foodservice, we surveyed 82 child care centers, kindergartens, and community children centers in Seoul by e-mail through the Seoul Metropolitan Government in November 2015. Using focus group interviews with directors of child care centers and kindergartens as well as dieticians of child care support centers who had conducted public foodservice in Seoul, the appropriateness of each standard was finally reviewed, and amendments to extend this standard were derived. Results of the survey show an understanding of 86.9% and an applicability of 80.7%. Moreover, the applicability of the evaluation items for assessing improvement of health foodservice practices at the child care center was 82.6%. Qualitative evaluation of the applicability of standards through focus group interviews identified four factors for extended application: necessity of a guideline for separate food ingredient suppliers, conformity of the basis and purpose of the item, consideration of contextual situations, and necessity of establishing a Seoul-level foundation. Therefore, guidelines for the standards should be suggested for those providing public food services for children. Furthermore, separate guidelines categorized by items that food ingredient suppliers need to provide should be mandatory or recommended. Evaluation of the applicability of the standards suggests that revising and supplementing the guidelines in order to extend the standards can contribute to health promotion and a sustainable environment for children using public foodservice. Follow-up studies and supports are needed for sustainable food and nutrition management programs.

  • In this study, on the basis of the seventh national mathematics curriculum, the achievement standards were developed to specify the objectives and contents of teaching-learning and the assessment standards were also developed to differentiate students' levels of achievement at school mathematics. The achievement standards were developed on the following guidelines; 1) to present the minimum standards based on the national curriculum, 2) to develop the standards based on the order of curriculum, 3) to suggest the minimum but ultimate achievement target, 4) to comprise not only of the intellectual but also of psychological spheres such as knowledge, function, attitude, aptitude, etc., and 5) to suggest the standards comprehensively and concretely. The standards were developed on the basis of the middle areas of contents of the curriculum in order not to be too comprehensive, nor to be too detailed. Learning activities, on the other hand, were provided for the assistance of instructions with emphasis on creativity rather than on the routine instruction. The assessment standards were established based on the following principles; 1) to establish the assessment methods, contents, and situations which are to be used for assessment, 2) to establish the criteria of classifying the assessed into the upper, intermediate and lower levels, 3) to develop the assessment standards in a proportionate balance to achievement standards, 4) to establish the intermediate level as a standard, and 5) to establish the minimum level in the contents, concepts, values and attitudes of basic learning. This study also suggested the exemplary test items including short-answer and open-ended questions while putting emphasis on students' real performance to increase their ability in solving problems rather than in calculating. In addition to the test items, it introduced the grading system developed to grade the items with concrete guidelines and to report students' achievement on doing mathematics.
