  • The visibility evaluation is significant for the development of construction equipment. The visibility evaluation follows the standards of ISO 5006, ISO 14401-1, and ISO 14401-2. The evaluation contains the operator's visibility and the visibility of rear-view mirrors. The operator's visibility includes the visibility test which requires the recognition of the rectangular line surrounding the machine by one meter and the circle with a 12 meter radius. This study describes the two evaluation processes for the development of the wheel loader. The first process is the light bulb shadow test by using a prototype wheel loader. The second process is based on computer simulation in virtual space. The advantages and disadvantages of computer simulation process are investigated.

  • Objectives: This study was conducted to review the overall concept of nutritional evaluation of infants and young children. Methods: Literature search was done to study definition, method and importance of nutritional evaluation of infants and young children. Pubmed and Google scholarship were used in the research. Search words were 'Nutritional evaluation', 'infants' and 'young children'. Results: Nutrition evaluation is mainly used by physical measurement, clinical evaluation, dietary intake survey, and biochemical test depending on the age and disease. The treatment method for 治未病, which is a concept of korean medicine, and 健兒法 for treating the concept of weak children are considered to have very high applicability in solving various problems found through nutrition evaluation in korean medical approach. Conclusion: Infants and children are the fastest growing period of their lives, showing rapid growth in physical, and emotional development along with rapid brain growth. Therefore, inadequate nutrition during this period affects mental and physical growth and development not only during that period but also throughout life. Nutrition evaluation is divided into regular evaluation that includes children in all growing seasons and screening evaluation for problem solving, and follow-up nutritional evaluation that evaluates nutritional status in the long run. For each nutritional evaluation, evaluation is conducted by physical measurement, clinical evaluation, dietary intake survey, and biochemical test. By comprehensively interpreting them, nutritional status is determined. This study provides basic data on the proper nutrition evaluation method to identify and correct nutritional problems such as growth level, nutritional deficiency, and nutritional excess early.

  • Currently, RC slab bridges in use in Korea account for most of the total bridges, and bridges with a service life of 20 years or more account for about 75%. However, most of these RC slab bridges have a span of less than 20m and are not included in the first and second types of facilities, so maintenance is very neglected. Therefore, in this study, field load test is performed on an aged RC slab bridge, and the performance evaluation is performed based on the structural response results (deflection, impact coefficient, natural frequency, etc.) of the bridge obtained through field load test. In addition, the performance evaluation results obtained through the load test are intended to be used as basic data for the damage evaluation process of the bridge currently under development.

  • The purpose of this research is to propose a set of basic guidelines for the construction of English test suites, a set of basic guidelines for the construction of Korean test suites to objectively evaluate the performance of machine translation systems. For this end, we constructed 650 English test sentences, 650 Korean test sentences, and developed the statistical methods and tools for the comparative evaluation of the English-Korean machine translation systems. It also evaluates the existing commercial English-Korean machine translation systems. The importance of this research lies in that it will promote an awareness of the importance and need of testing machine translation systems within the Natural Language Community. This research will also make a big contribution to the development of evaluation methods and techniques for appropriate test suites for Korean information processing systems. The results of this research can be used by the natural language community to test the performance and development of their information processing systems or machine translation systems.

  • Dissolution test has been performed to control drug quality and to predict in vivo drug release profile of solid dosage forms, so there's a drift towards setting dissolution test instead of disintegration test. However, some solid dosage forms in Korea Pharmaceutical Codex (KPC) are not established the dissolution test yet, so these monographs are necessary to set the specification of dissolution test. In this study, we developed the specification and test method of dissolution test for itopride hydrochloride tablets and tiropramide hydrochloride tablets which are not established the dissolution test yet. According to the "Manual for Guideline Application for Validation of Analytical Procedures" and "Guidelines on Specification of Dissolution test for Oral dosage form" of Korean Pharmacopoeia (KP), we validated and established each development method. Based on the preliminary dissolution profile, we set the dissolution condition(paddle apparatus, pH 1.2 media, 50 rpm). For this condition, we performed the main dissolution test to determine the specification (45 min, 85%). Finally, we validated each analytical method by specificity, linearity, accuracy and precision. These developed methods will be included the next supplement of KPC and also contributed to the quality control of medicines.

  • Failure testing is a test that verifies that the system is operating in accordance with failure response requirements. A typical failure test approaches the operating system by identifying and testing system problems caused by unexpected errors during the operational phase. In this paper, we study how to evaluate these Failure at the software development stage. Evaluate the probability of failure due to code changes through the complexity and duplication of the code, and evaluate the probability of failure due to exceptional situations with bugs and test coverage extracted from static analysis. This paper studies the possibility of failure based on the code quality of software development stage.

  • 최근 자동차는 안전성, 편리성, 친환경 등의 목적으로 개발되고 있다. 특히, 자동차 안전성에 대한 인식이 중요하게 바뀌고 있다. 이에 따라, ADAS 개발로 인한 안전 시스템들이 등장하였다. 그러나 ADAS의 개발과 시험 평가를 통해 양산 되는 기간은 상당히 오래 걸린다. 따라서 본 논문에서는 ADAS 개발과 시험 평가에 필요한 기간을 단축시키기 위해 브레이크 다이나모미터를 개발 하였다. 또한 개발한 브레이크 다이나모미터는 국제 표준인 JIS D-0210을 만족하며, ADAS의 모드별로 사용자가 시험 조건과 시험 방법을 선택 하여 제동력을 평가할 수 있다. 그리고 개발하는 브레이크 다이나모미터의 신뢰성 검증을 위해 선행 연구에서 제안한 ACC, LKAS, AEB의 시나리오를 사용하였다. 개발한 브레이크 다이나모미터는 시험값과 선행 연구를 통해 제안된 ADAS 모드별 이론식에 의한 계산값을 비교하여 신뢰성을 검증하였다. 또한, 향후에는 ADAS의 실차시험이 불가능한 환경에서 ADAS 모드별 브레이크 부품의 성능 평가가 가능할 것으로 기대 된다.

  • In this paper, a new evaluation system was developed for ride comfort test and vibration level test on railway vehicles. These tests are carried out by applying different equipments and test procedures before now. But this developed system is capable of ride comfort test and vibration test by a single integrated system. Also, the evaluation algorithm for the ride comfort was compared and verified by simulation results with VAMPIRE software. With this developed system, the comfort in a passenger coach and the vibration in a freight car were verified by the results in field test.
