  • There are a variety of evaluation methods used to evaluate and provide feedback to students, recognize shortcomings, and establish future plans. The purpose of the academic achievement evaluation is to check whether the student understands the content taught, identify areas that the student is unfamiliar with or misunderstand, and then provide supplementary study to prevent learning deficits. Multiple choice has been the evaluation system in Korea since the early 1970s, influenced by Tyler's goal-centered evaluation model that evaluates achievement of educational goals and Bloom's educational goal classification system. The most important item in education is the evaluation of whether you have properly understood the lesson and how deeply you know it. Therefore, in this study, in order to minimize cases where test takers stochastically answer the correct answer in a multiple-choice evaluation, the change in the standard deviation of grades was analyzed by applying a grading method that assigns negative points to incorrect answers. As a result of the study, it was found that the average score of the incorrect response evaluation was 1 to 4 points lower, and the standard deviation was wide. This showed that the test taker's discrimination ability was high in the wrong answer appraisal type.

  • Purpose: The Korean government has implemented a Barrier Free Certification System since 2008 to create a secure and convenient environment for the socially disadvantaged. The drastic increase in the number of BF-certification facilities is expected due to the revision of the system and increasing the number of certification institutions. An analysis of individual evaluation items needs to be made for the BF-Certification with public confidence. Method: Korean standard, International Standard(ISO/FDIS 21542, 2011), German Standard(DIN 18040-1, 2010), Austrian Standard(${\ddot{O}}NORM$ B 1600, 2017) and Swiss Standard(Norm SIA 500 / SN 521 500, 2009) were investigated and analyzed. A comprehensive improvement plan is proposed by comparing details of the aforementioned standards and the evaluation items of BF-Certification. Results: Many problems arise in applying existing Barrier-free standards due to changes in population structure, environmental change and the use of powered wheelchairs. International standards are being improved to solve these problems. The korean standards also require improving of the Barrier Free Law and Certification System, which reflect these trends. In korean cases, standards such as the size of the doors (width and height), the Unobstructed Manoeuvring Space and Clear Space at the Latch side of the Door are required to improve standards in accordance with international standards. In addition, the expression of laws and evaluation items of BF-Certification should be clearly defined. And the application of visual contrast standards for the enhancement of perceptions presented in international standards should be considered. Implication: Barrier Free related legal standards and evaluation items of BF-Certification that are used in Korea are required to be revised in consideration of social and environmental changes. Comprehensive improvements should be made through detailed review.

  • Kimono sleeves have continuously appeared in modern fashion as a design motif and this trend has become increasingly prevalent recently. However for research in the area of clothing composition for kimono sleeves in Korea, there has been a lack of development of master patterns based on basic data from the analysis of the standard body type of Korean people and finalized designs based on comparative experiments and analysis of pre-existing research Thus, there is no ideal master kimono sleeve pattern development research based on the examination of the results of the analysis of the standard body type of Korean people. Therefore by recognizing the importance of developing a master kimono sleeve pattern, this research aims to present a practical master kimono sleeve pattern for the standard body type of someone in their 30s. First, the four master patterns were collected and a dressing evaluation was conducted, and by selecting and improving one of these master designs, a final research master pattern was developed after a second dressing evaluation. Through this research, it was possible to design a master kimono sleeve pattern appropriate both externally and functionally for the standard body type of someone in their 30s, which has not been a consideration in previous research.

  • Objectives: This study aimed to present a government-led accreditation system for upgrading the quality control of herbal medicine by introducing the process and evaluation standard of external herbal dispensaries (EHDs) of traditional Korean medicine (TKM) clinics in South Korea 2018 to refer to other countries where herbal medicine were used similarly in Korea. Development Process: We organized an EHD accreditation committee for the establishment of an accreditation system. The committee consisted of 9 experts: an official of the Ministry of Health and Welfare (MoHW), a professor expert of TKM, a good manufacturing practice expert, a hazard analysis and critical control point expert, and an accreditation system expert. After 3 meetings, a draft of the evaluation standard and evaluation system was established in 2017. Based on the draft, a pilot test was conducted to determine the applicability of the evaluation standards in 2017. Two additional meeting was held to confirm the accreditation standards and was finalized in 2018. Results: The evaluation standard for EHDs was developed. In the case of herbal medicine EHDs, the evaluation standard consisted of 9 evaluation categories, 25 evaluation parts, and 81 evaluation items were developed. The results of the evaluation of the pilot tests are as follows, and the results show that there is a deviation between the EHDs. Conclusion: As a world's first, Korea MoHW successfully launched the accreditation system for upgrading the quality control system of herbal medicine not approved by Korea's Ministry of Food and Drug Safety in 2018. Our report hope to provide a good reference to other countries where having similar herbal medicine system in South Korea hoping to make better quality control of herbal medicines.
