  • The objective of this study is to present the inspection standards of motorcycle brake system affecting motorcycle traffic accident. The inspection standards of motorcycle brake system recommended by CITA (International Motor Vehicle Inspection Committee) are studied. The brake performance for preventing the traffic accident is assessed by the brake efficiency. Considering the KMVSS (Korean Motor Vehicle Safety Standards) and the inspection standards of CITA, United Kingdom and Japan, the brake performance in the inspection standards of motorcycle is suggested. It is recommended that the efficiency of independent front and rear brakes are 40% and 27%, respectively. It is recommended that the efficiency of combined front and rear brakes is 50%.

  • Three wind-tunnel simulations of the atmospheric boundary layer (ABL) flow in suburban country exposure were generated for length scale factors 1:400, 1:250 and 1:220 to investigate scale effects in wind-tunnel simulations of the suburban ABL, to address recommended wind characteristics for suburban exposures reported in international standards, and to test redesigned experimental hardware. Investigated parameters are mean velocity, turbulence intensity, turbulent Reynolds shear stress, integral length scale of turbulence and power spectral density of velocity fluctuations. Experimental results indicate it is possible to reproduce suburban natural winds in the wind tunnel at different length scales without significant influence of the simulation length scale on airflow characteristics. However, in the wind tunnel it was not possible to reproduce two characteristic phenomena observed in full-scale: dependence of integral length scales on reference wind velocity and a linear increase in integral length scales with height. Furthermore, in international standards there is a considerable scatter of recommended values for suburban wind characteristics. In particular, recommended integral length scales in ESDU 85020 (1985) are significantly larger than in other international standards. Truncated vortex generators applied in this study proved to be successful in part-depth suburban ABL wind-tunnel simulation that yield a novel methodology in studies on wind effects on structures and air pollution dispersion.

  • The purpose of this study was to investigate weight gain during pregnancy based on pre-pregnant Body Mass Index, to compare eating habits based on the recommended standards for weight gain presented by the Institute of Medicine, and to identify factors affecting the weight gain of pregnant women. The subjects were grouped into three categories according to the recommended weight gain standards presented by the Institute of Medicine: the inadequate group, the adequate group and the excessive group. The excessive group had a significantly higher pre-pregnant Body Mass Index than that of the two other groups. Based on a comparison of the eating habits and nutrient intake of the women to the recommended standards for weight gain, the excessive gain group had large meals and ate more frequently outside of the home when compared to the pre-pregnancy period. Based on an analysis of correlations between weight gain during pregnancy and diet factors, the adequate gain group had positive correlation between weight gain and a "balanced meal" and had negative correlation with "convenience meals". The excessive gain group had a positive correlation with "convenience meals" and had a negative correlation with "meal skipping." All the pregnant women were more frequent in the "overeating categories" and all ate more "fruit," as their weight gain was higher. In particular, the excessive gain group was frequently evaluated as "overeating". These results indicate that the factors affecting weight gain during pregnancy were the Body Mass Index before pregnancy, eating types, and eating habits. As the Body Mass Index before pregnancy was higher, the ingestion of a 'balanced meal' was less, and overeating and gluttony were more frequent. Therefore weight gain was enhanced.

  • The baseline selection is the first and important step to analyze magnetocardiography (MCG) parameters. There are no difficulties to select the baseline between P- and Q-wave peak (P-Q interval) of MCG wave recorded from healthy subjects because the P-Q intervals of the healthy subjects do not much vary. However, patients with ischemic heart disease often show an unstable P-Q interval which does not seem to be appropriate for the baseline. In this case, T-P interval is alternatively recommended for the baseline. However, there has been no study on the difference made by the baseline selection. In this study, we studied the effect of the different baseline selection. MCG data were analyzed from twenty healthy subjects and twenty one patients whose baselines were alternatively selected in the T-P interval for their inappropriate P-Q interval. Paired T-test was used to compare two set of data. Fifteen parameters derived from the R-wave peak, the T-wave peak, and the period, $T_{max/3}{\sim}T_{max}$ were compared for the different baseline selection. As a result, most parameters did not show significant differences (p>0.05) except few parameters. Therefore, there will be no significant differences if anyone of two intervals were selected for the MCG baseline. However, for the consistent analysis, P-Q interval is strongly recommended for the baseline correction.

  • Age, sex and the amount of activity determine recommended dietary allowances. So the method of developing RDA and their levels have been revised according as the physical condition of a nation improves and the amount of activity changes along with the variety of social situations. It can be seen from records that in Korea the absolute nutrient requirements for the people in Chosun Dynasty were first published in 1922. After that, in 1941 Gui Dong Han expressed his view that the standard health diets for the Japanese would be suitable for the people in Chosun Dynasty. In 1960, the temporary nutrition standards for the Koreans were established by the Ministry of the Health and Social Affairs. For these standards, males and females were respectively divided into three groups by age and nine nutrients were recommended for each group. In 1962, The Korean Association to FAO published the RDA for the Koreans. Since then, regular researches have been done. For these allowances, there were 16 age groups of men and women and ten nutrients recommended for each group. On the first revision in 1967, the fat allowance was presented at the ratio (12%) of fat calorie to total calories with no change in the number of age catagories and in the kinds of nutrients. And the basis of the riboflavin allowance was changed from the level of protein intake to that of energy intake. On the socond revision in 1975, there was brought 19 are catagories and ten nutrients recommended. On the third revision in 1980, age catagories increased to 22, and ten nutrients were recommended. On the fourth revision in 1985, there remained 21 groups by uniting the early and later periods of pregency. On the first revision in 1967, the recommended energy allowance was 3000 kcal, the highest level. Since then it has gradually been reduced. And it can be noticed that the protein allowance was high when food was difficult to obtain.

  • Objective: The provision of pharmaceutical care service in compliance with good pharmacy practice (GPP) standards is important, but there is lack of studies to investigate the barriers that significantly hinder community pharmacies in Korea from adhering to the standards. This study was aimed to identify the major barriers to provision of pharmaceutical care service in compliance with the proposed pharmacy practice standards which have been developed based on the GPP standards recommended jointly by WHO and FIP. Methods: Questionnaires reviewed by the expert committee were posted for 32 days on the website which is most frequently accessed by community pharmacists. The respondents completed them by checking the scores (Max=5, Min=1) for major barriers to provision of pharmaceutical care service focusing on patient information management and drug use review process in prescription fillings. The answered scores were automatically collected using online data processing. Mean differences between scored data were assessed by ANOVA. Results: Total 321 pharmacists participated in the survey. Results indicated that 'difficulty of diagnosis identification' (m=3.92, SD=1.21), 'lack of time' (m=3.48, SD=1.22) and 'lack of updated clinical information' (m=3.17, SD=1.10) were the major barriers to provision of pharmaceutical care service in patient information management. The main barriers to drug utilization review were 'lack of time' (m=3.32, SD=1.21), 'lack of updated clinical information' (m=3.11, SD=1.17), and 'negative feedbacks or refusals from prescribers' (m=3.00, SD=1.38). There were significant differences among the groups by location, employed number of pharmacists and acceptability to the proposed GPP standards. Conclusion: Difficulties in managing patient clinical information and lack of time were found to be the major barriers in providing pharmaceutical care services in community pharmacies in Korea. Further research is recommended to determine ways to reduce these barriers in order to provide quality pharmaceutical care service that is in compliance with the internationally recognized GPP guidelines.

  • Objective: The aim of this study is to give ergonomists the brief summary of the recently published ISO standards on human-system interaction and tips for application of the standards. Background: Standard developers did hard work on developing a standard in a concise manner. But most of standards are often bulky in volume. Readers of the standards are difficult to catch key points from the voluminous contents of standards and intermingle among them. Method: Focused on newly developed display/control technology, this study reviewed the 14 ISO standards on human-system interaction published during 2008-2013 and summarized key points from them. Results: Schematic diagrams and tables concisely illustrated the processes, procedures, dimensions, or best practices recommended by the standards concerning conception, design, and usability testing for consumer products. Conclusion: The standards provided the minimum level of requirements on design and evaluation on the physical input devices, electronic displays, and control interfaces based on the current state of technology. But the minimum requirements specified in the standards nowadays become mandatory ergonomic requirements in global trade world. Application: Ergonomists can take a quick and broad view on international standardization activities on newly developed display/control technology from this summary study.
