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.

200 N급 기체메탄/액체산소 소형로켓엔진의 성능시험평가 수행되었다. 산화제 공급압이 증가함에 따라 연소압과 추력이 증가하였으며, 이에 따라 비추력과 특성속도 및 그 효율이 증가하였다. 특성속도는 약 90%의 성능효율로 측정되었다. 시험조건의 연소실 종횡비 변화는 추력성능에 영향을 미치지 않았다. 또한, 시험결과의 신뢰도 확보를 위하여 불확도평가를 수행하였다.

In this study a safety evaluation method is presented for a ADAS vehicle to be tested in collision situation when multiple vehicles are present on a single lane. Test scenarios are developed based on Euro-NCAP assessment scenarios, accident database and related simulation results in previous works. An automated evaluation system that is called as the K-target mover is used for active safety evaluation experiments. The experiments are conducted with two types of tests. First, the rear-end collision tests with 25% and 50% overlap for the test vehicle and target vehicle are conducted with the two kinds of test vehicles. On the other hand, the rear-end collision tests which include multiple vehicles in a single lane with 25% and 50% overlaps, are also conducted. Experimental results show that the test vehicles with ADAS cannot recognize the collision situation sometimes in the developed test scenarios, even in the case that the test vehicle showed stable performance in the simple overlap scenarios.

Needs of fuel's performance evaluation for the dual-cooled fuel pellet (annular shape) necessitate the irradiation test in the test reactor. Irradiation test rig for the HARARO reactor, which is a special-purposed equipment used for material, irradiation and creep test, must satisfy the operational requirement on the hydraulic characteristics and structural integrity. In this paper, pressure drop and flow-induced vibration test for the newly developed non-instrumented test rig were carried out using FIVPET as a out-pile evaluation test. The test results show that the new test rig satisfy the HANARO operational requirement with sufficient margin. The spectral response characteristics of the flow-induced vibration of the test rid were also discussed.

In recent years, the safety of sunscreens has been challenged based on the reports of its adverse effect on users; dermatitis, allergic contact dermatitis, photoallergic contact dermatitis. To investigate a correlation between sun protection factor (SPF) and the safety of sunscreens, we measured in vitro SPF index using homosalate as a standard and examined the toxicity tests on cosmetics; primary skin irritation tests, ocular irritation test, and skin sensitization test.(omitted)

When a concrete member is damaged by fire accident, it can lose its strength. And the degradation rate of losing its strength affected by many environmental conditions. But there is few research for equation for strength evaluation of fire-damaged concrete. Besides, it is impossible to destruct structural member from the building for the evaluation. So, I will suggest a new equation for strength evaluation of fire-damaged RC beam using non-destructive test. For this purpose, the researchers are exploring the performance of non-destructive testing methods using Ultrasonic test, Schmidt Hammer test and Coring test against fire damaged concrete specimen.

Systems engineering test and evaluation technology development program for (Korea) Express Tilting Train(TTX) system in progress is a national large system development program that is not only a large-size and complex but also muti-disciplinary in nature. For the TTX test and evaluation technology development, verification requirements that could verify system function and performance, should be derived from system specification. Hereafter, this could be listed as items of test. System engineering process establishes traceability between items of test and system requirements. These tasks could be accomplished by the schema. Using the Core, a system engineering tool, TTX program could be database and oter system related to TTX program will be developed effectively and efficiency.

This study is to establish test method and evaluation technology of drive system appropriate to high speed train. The transmission system of high speed train serve in the severe condition compared with those of other trains, namely, they have to transmit high power to run with high speed and they have to make maximum use of the limited space. This paper reports the reviews and results for the test and evaluation method of reduction gearbox for high speed train and discusses various test items and methods about assembly and parts of gearbox transmission.
