  • This study examined the characteristics of brain's reaction pattern concerning the preference for product images and compared them with the result of subjects' intuitive evaluation of their preference for the same materials. Two tests were conducted; the first one that calculated comfort properties based on brainwave measurements in order to examine the impression given by the images of products presented separately, one-by-one, and the second one that had subjects evaluate the preference directly by comparing the images of all products simultaneously. The first test was titled 'Independent Cognitive Response' and the second test, 'Relative Cognitive Response', and their characteristics were as follows. In the 'Independent Cognitive Response', the state of emotion was expressed in absolute values based on the comparison with the information accumulated through the subject's own experience and the feeling expressed as 'pleasant' or 'unpleasant' persisted as absolute values. In the 'Relative Cognitive Response', the state of emotion relative to the information of other images compared in the stage of perceiving the images was expressed, and in this case, the state of emotion described as 'calm' or 'excited' acted as relative values.

  • The objective of this study was to determine whether any pretreatment parameters were associated with pharmacological effect or toxicity parameters after vincristine administration and to describe a mathematical model, which explains the interpatient pharmacodynamic variability. The relationship between patient characteristics and vincristine dose and hematological toxicity were evaluated. 68 pediatric and adolescence patients and 107 adults with acute lymphoblastic leukemia were treated with vincristine $1.5mg/m^2/day$ IV and other anticancer drugs as scheduled. Complete blood counts and other blood test results were obtained. The input variables were age, gender, weight, lean body weight (LBW), height, body surface area, vincristine dose and total vincristine dose. The outcome measures were nadir values (white blood cells, absolute neutrophil counts, hemoglobin, and platelets); the absolute decrease, relative decrease, and survival fraction of blood cells. Polynomial regression analysis was carried out to determine the other significant covariates. The variability of $WBC_{nadir}$ was modeled with good precision and accuracy with a two-covariate model. This model should be validated and improved on with further clinical data. We believe that such pharmacodynamic modeling should be explored further to determine its performance and clinical relevance compared with modeling using pharmacokinetic parameter.

  • Objectives: HMCO5 is an extract obtained from 8 different herbal mixtures. We undertook a safety evaluation of HMCO5 for a dose range finding (DRF) toxicity test in specific pathogen free (SPF) Sprague-Dawley (SD) male and female rats. Methods: The male and female rats were divided into 4 groups, respectively; G(0), treated with distilled water: G(1), treated with 222 mg/kg HMC05: G(2), treated with 667 mg/kg HMC05, and G(3), treated with 2,000 mg/kg HMC05; HMC05 was administered orally for 4 weeks. The safety evaluation examined clinical signs, mortality, body weight, food consumption, water consumption, ophthalmic findings, urinalysis, hematological values, absolute & relative organ weights, and necropsy findings during the tests. Results: There were no changes in clinical signs, mortality, body weight, food consumption, water consumption, and ophthalmic findings examined during the test periods. In serum biochemical values, triglyceride was increased in male group G(3) and Na$^+$ decreased significantly in male groups G(2), G(3) and G(4). In male group G(4), spleen weight decreased relatively and increases of absolute & relative left ovary weights were found. In addition, an adhesion of liver to diaphragm was found in male group G(2). However, we could not find any dose-interrelationships in these changes. Conclusions: These results indicate that HMC05 extract did not show any toxicity in the DRF toxicity study. Therefore, it suggests that establishment of 1,000, 333 and 111 mg/kg dosages are moderate in a repeated dose 26-week oral toxicity study of HMC05.

  • Following the opening of eleven medical schools in Korea in the 1980s, the issues of standardization and accreditation of medical education came to the forefront in the early 1990s. To address the medical community's concern about the quality of medical education, the Korean Council for University Education and Ministry of Education conducted a compulsory medical school evaluation in 1996 to see whether the medical schools were meeting accreditation standards or not. The evaluation was a "relative evaluation" rather than an "absolute evaluation." The Accreditation Board for Medical Education in Korea (ABMEK), established in 1998, was a mere voluntary organization, but with the full support of the Korean medical community, it successfully completed its first cycle of evaluations on all 41 medical schools from 2000-2004. The history of medical education evaluation activities, including those of ABMEK, was not well recorded. In 2004, ABMEK changed its name to the Korean Institute of Medical Education and Evaluation (KIMEE) as a corporate body and the government paid much attention to its voluntary accreditation activities. In 2014, the Ministry of Education officially recognized the KIMEE as an Institute for Accreditation of Higher Education Evaluation. The most important lesson learned from the history of ABMEK/KIMEE is the importance of cooperation among all medical education-related organizations, including the Korean Medical Association.

  • Optical pick-up is a core component for data read/write operations in optical disc drives, and an optical pick-up performance evaluator is an instrument used to analyze the overall performance of an optical pick-up. Due to inevitable errors in an analog measurement circuit, resultant evaluation data is not guaranteed to be accurate. In this paper, a calibration method for an optical pick-up performance evaluator is proposed to ensure evaluation accuracy. Measured data is corrected by a 1st order correction function, and a calibration process based on least-square method is utilized to obtain correction coefficients of the correction function. The proposed calibration method is applied to experiments, and enhanced accuracy is presented with resultant evaluation data.

  • A recently developed methods for on-site calibration of the current transformer (CT) comparator system have been reviewed in the paper. The method utilizes several traveling standards, which consist of the CT, non-reactive standard resistors, wide ratio error CT, and shunt resistors. The traveling CT is used for absolute evaluation of a standard CT belonging to industry. The non-reactive standard resistors and a wide ratio error CT are used for the linearity check of errors in the current comparator. The shunt resistors are used for evaluation of CT burden of industry.

  • An experimental modal analysis and dynamic stiffness evaluation of a moving body structure of a high speed machining center are presented in this paper. The natural frequencies and corresponding modes, and dynamic compliance of a moving body structure of high speed machining center are investigated by using F.E.M., hydraulic exciter test, and impulse hammer test. The lowest three natural frequencies were found to be 56.6 Hz, 112.7 Hz, and 142.7 Hz by FEA respectively, while those were 55 Hz, 112 Hz, 131 Hz by experimental analysis. Furthermore, both computed and measured absolute dynamic compliances of the moving body structure in iso-direction showed good agreement especially at the first two mode frequencies. With our experimental data, the dynamic characteristics of the machining center can be exploited to get a new development of structural dynamic design and modification.

  • Rubber material properties and useful life evaluation are very important in design procedure to assure the safety and reliability of the rubber components. In this paper, the evaluation of characteristics and useful life prediction of rubber component for elevator cabin were experimentally investigated. The material test and accelerated heat-aging test were carried. Rubber material constants were obtained by curve fittings of simple tension, pure shear and bi-axial tension test data. Heat aging test results changes as the threshold are used for assessment of the useful life and time to threshold value were plotted against reciprocal of absolute temperature to give the Arrhenius plot. By using the rubber material and component test several useful life prediction equations for rubber component were proposed. Predicted useful life of rubber component for elevator cabin agreed fairly with the experimental lives.
