The international standard for FT-IR gas analysis of fire effluents in ISO 5660-1 cone calorimeter has been being developed in ISO TC 92. A comparison of the round-robin test of WD 21397 was conducted with six participating laboratories in 2018. The test specimens were PMMA, rigid PU foam board, and PVC flooring. The measurement quantities were the time-to-ignition, peak heat release rate, total heat release, and effective heat of combustion for a cone calorimeter test and peak gas concentration, gas generation, and gas yield for FT-IR gas analysis. No outliers were identified. For the cone calorimeter quantities, the repeatability and reproducibility were 1.5% and 9.8%, respectively. For FT-IR gas analysis, the repeatability and reproducibility was 12.9% and 27.9%, respectively.

Fire resistance and thermal stability of polypropylene composite systems were investigated by using several halogenated fire-retardants such as decabromodiphenyl oxide (DBDPO) and chlorinated paraffin wax (CPW). The fire resistance of composite systems was thoroughly examined by measuring limited oxygen index (LOI, ASTM D2863, ISO 4589) and characteristic properties of cone calorimetry(ASTM E1354, ISO 5660) heat release rates (HRR), time to ignition (TTI), total heat release (THR), effective heat of combustion (EHC), mass loss rates, etc. Comparing the cone calorimetry experimental results of the halogen flame retardants, DBDPO exhibited twice higher efficiency than CPW in polypropylene systems, and the LOI also showed similar trends to cone calorimetry. The thermo-oxidative stability of the composite systems was increased about 30-5$0^{\circ}C$ in thermogravimetry analysis.Collectively, the combustion, extinction and thermally-stable characteristics of flame retardants were identified in this study.

A calorimeter of 2-ton thrust level rocket engine chamber has been developed to measure the wall heat flux. The liner of the chamber is made of copper-chromium alloy to maximize the heat transfer performance and structural strength. 1-D design code based on empirical correlations has been used for the prediction of the global thermal characteristics while 3-D CFD has been applied for the verification of local cooling performance. The predicted average wall heat flux at the throat is 43 $MW/m^{2}$ for the combustion chamber pressure of 53 bar. The chamber structure is confirmed to be safe at the pressure of 150 bar through 2-D stress analysis and measurement of the strain of the test species. Finally, the test of pressurizing the calorimeter chamber has been performed with water at the pressure of 150 bar in room temperature environment. No thermal damage has been detected after the hot-fire test in the test nozzle of same cooling performance with the developed calorimeter though the measured throat heat flux is higher than the design value by 10%.

Calorie, mineral content and amino acid composition of four japonica, seven $j{\times}indica$ and one waxy milled rice were analyzed. No significant differences in calorie, mineral content and amino acid composition were found between japonica and $j{\times}indica$ rice varieties. Only the variation of methionine among varieties was noticed. The most limiting amine acid of milled rices was lysine.

Obesity is an excess of body fat frequently resulting from an imbalance between energy intake and expenditure, raises the risk of morbidity from chronic diseases such as hypertension, dyslipidemia, type 2 diabetes, coronary heart disease, stroke, fatty liver and osteoarthritis. Recently we experienced a 51 years old obese woman who was accompanied with hypertension, dyslipidemia and osteoarthritis. Through weight reduction program(very low calorie diet, Chegameuiintang, exercise) during 3 months, total weight loss was 17.0kg, her condition was improved.

Some major properties such as a heat release rate have been measured experimentally for the validation of fire model and the clarification of fire phenomena as the study is more rigorous recently. Although the reduced-scale experiment also provides the basic data and the physical understanding in fire study, it is not enough to explain real fire problem directly because there is no exact analogy theory between a real fire and the reduced scale model. Therefore, large cone calorimeter have been built and used in a few foreign countries for the measurement of large scale fire. This paper addressed the theoretical background and the description of key features in the design of the facility. It will be a useful guide for implementation of the large scale cone calorimeter in the future.

The goal of this study was 1) to compare the physical activity between the normal(NO) and obese (OB) group at baseline and 2) to investigate responses of the physical activity to a 24-week walking exercise program in both groups. A total of 29 middle-aged women was classified NO and OB group based on the BMI($25kg/m^2$). Walking exercise was designed to energy expenditure of 500 kcal per day, with a frequence of 3 days per week for 24 weeks. Body composition(Weight, BMI, BF(%), Hip, WHR) were measured at the baseline and after the walking exercise program(24 week). Physical activity were measured during 24 week for wellness convergence in the digital age. In conclusion, the current findings of this study indicate that 1) physical activity is not difference in both groups at baseline 2) 24-week walking exercise program is an effective means of improving physical activity in both NO and OB groups.
