  • 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.

  • The primary research objects of this study is to evaluate an importance of supplier selection factors as an index according the level of product standardization and to present the evaluation model for supplier selection. For this purpose, this study adopts the AHP method to calculate the importance of supplier selection factors. In this study 16 factors which affect on the supplier selection decision making are classified into three factors-product supply related factor, product related factor, management ability related factor. Results also indicate that standardized products are much more dealt by means of on-line compare to customized products. It means the buyer opportunities is potentially an increase in the amount of current supplier re-evaluation, which may lead to new suppliers being considered more often.

  • Construction Technology Service is currently hardly managed due to failure to offer standard management system of service performance, company performance, and business evaluation in every Ordering Agencies. After Construction Technology Promotion Act is enforced in May 2014, Ordering Agency obligates them to report to Minister of Land and Transportation within 10 days upon contract/ amendment/ completion. In 2013, in advance to enforcement of this law, performance management system for construction technology service was developed for a test run. However this system only applies to main contractors while management and operation of subcontractors are unavailable that causes problems on connection and integration with Experience Management Trustee. Therefore, this research will establish systematic foundation that enables real-time information of service performance and evaluation of subcontractors to result standardization of performance and evaluation for public ordered services.

  • This paper investigates the performance of a vehicular rear-view camera through quantifying the image quality based on several objective criteria from the ISO (International Organization for Standardization). In addition, various experimental environments are defined considering the conditions under which a rear-view camera may need to operate. The process for evaluating the performance of a rear-view camera is composed of five objective criteria: noise test, resolution test, OECF (opto-electronic conversion function) test, color characterization test, and pincushion and barrel distortion tests. The proposed image quality quantification method then expresses the results of each test as a single value, allowing easy evaluation. In experiments, the performance evaluation results are analyzed and compared with those for a regular digital camera.

  • Dysarthrias are a sort of neuromotor disorders because of the weakness of neuromotor controls. They are classified in six types on the basis of Mayo clinic research: flaccid, spastic, ataxic, hypokinetic, hypekinetic and mixed types. Five dysarthria types are investigated in this study. MRI, EMG, neuropathological tests are essential diagnostic processing. Visi-Pitch and Spectrgraphy, CSL are used for assessing dysarthria speech. Maximum phonation time, diadochokinetic rate, Voice Onset Time and substitution rate are the speech evaluation parameters. Maximum phonation time and diadochokinetic rates are the lowest in case of spastic and ataxic dysarthrias. Spastic dysarthria shows the substituted glottalized consonants. However, flaccid, ataxic and hypokinetic dysarthrias show the substituted aspirated consonants. VOT is the longest for hypokinetic dysarthria and the shortest for ataxic dysarthria. Jitter shows higher percentage in comparison with control group. Speech evaluation using experimental phonetic instruments help create on international standardization of speech evaluation for speech disorders.

  • The dissolution test method and an analytical procedure by HPLC were developed and validated for nafronyl oxalate capsules and tramadol hydrochloride capsules. These drugs were not yet characterized by the dissolution specifications in the Korean Pharmaceutical Codex. So, with each reference and test drugs, we did the preliminary and standard experiments based on the Korean Pharmacopeia Guideline of dissolution testing for solid oral dosage forms. The dissolution test for nafronyl oxalate capsules was carried out under sink conditions as follows: dissolution medium phosphate buffer pH 6.8, paddle rotation speed 100 rpm and vessel volume 900 ml. More than 80% of its label amount was released within 30 min in this method. Also the dissolution test for tramadol hydrochloride capsules was carried out under sink conditions as follows: dissolution medium water, paddle rotation speed 50 rpm and vessel volume 900 ml. More than 90% of its label amount was released within 15 min in this method. The dissolution samples were analyzed with a validated HPLC analytical procedure. The analytical methodology showed acceptable values in terms of specificity, linearity, precision and accuracy. The dissolution test methods described above were adequate for the purpose and may be proposed as a pharmacopeial standard to assess the performance of nafronyl oxalate capsules and tramadol hydrochloride capsules. Furthermore, the outcomes of this study were expected to help create an environment where safe and high quality drugs would be distributed on the domestic market making contributions to advancing public health.

  • This study is a continuous work for the standardization of children's kimchi preparation. In order to find out the proper red pepper powder for children's kimchi, four kinds of red pepper powder(A, B, C, D) sold in Kyungsang province were used as samples. The proximate composition, color value, capsaicinoids concentration and sugar content in four kinds of the red pepper powder were determined, and sensory evaluation of kimchi Prepared with those was carried out for different fermentation times. Moisture contents of red pepper powder A, B, C and D were in the range of 11.59~13.48%. Lipid and ash contents of samples were in the range of 7.59~8.39% and 4.34~7.45%, respectively. In comparision of color values measured by a Hunter colorimeter, red pepper powder A showed the highest value for a and b values. Also A showed the brightest color as measured in ASTA color and L value. Capsaicin concentration of D and dihydrocapsaicin concentration of C were found to be the highest among the sanlples. The capsaicin equivalent was in tile order of D>C>A>B. The content of total sugar was in the order of B>A>D>C. In the sensory evaluation of children's kimchi prepared with four kinds of red pepper powder, the color and total acceptability of kimchi prepared with A were found to be the best. The results of sensory evaluation between kimchi prepared with A and school supplied kimchi showed that the former was better. And the composition of A red pepper powder was as follows: capsaicin equivalent 24.l5mg%, total sugar content 15.79% and ASTA color value 178.2.
