The purpose of study is to confirm a acceptable range of data errors in data collecting. To examine a acceptable range of data errors, emission level is calculated for a vehicle flow and heavy vehicle percentage as a function of small-sized velocity. According to road selected, noise level of detail influence road noise calculations. It can be concluded that a vehicle flow raised an error less than 5000(veh/h) for a maximum error in emission level of 3.01dB, and the more a heavy vehicle percentage have a low value, the more emission level is a slight difference. This analysis gives insight regarding the accuracy of traffic flow data that is needed to reach a certain level of accuracy for the resulting noise level.

Design variables for suspension systems cannot always be realized in the actual suspension systems due to tolerances in manufacturing and assembly processes. In order to deal with these tolerances, design variables associated with kinematic configuration and compliance characteristics of suspensions are treated as random variables. The reliability of a design target with respect to a design variable is defined as the probability that the design target is in the acceptable design range for all possible values of the design variable. To compute reliability, the limit state, which is the boundary between the acceptable and unacceptable design, is expressed mathematically by a limit state function with value greater than 0 for acceptable design, and less than 0 for unacceptable design. Through reliability analysis, the acceptable range of design variables that satisfy a reliability target is specified. Furthermore, through sensitivity analysis, a general procedure for optimization of the design target with respect to the design variables has been established.

Objectives: The aim of this study was to investigate the exposure and risk assessment of residents near asbestos mines in Korea. Methods: To assess asbestos types and airborne concentrations, air monitoring was performed in the neighborhoods of Kwangcheon (KC) and Sinsuk (SS) mines, which were leading South Korean mines in the past. In addition, activity-based-sampling (ABS) of residents' particular activities were conducted in order to estimate the Excess Lifetime Cancer Risks (ELCRs) for the residents. Conclusions: The average concentration of airborne asbestos in KC was 0.0014 f/cc and 0.0015 f/cc by PCM and TEM, respectively. In SS it was equal at 0.0012 f/cc by PCM and TEM. No statistically significant difference was found in the average concentration of airborne asbestos between the two mines. The average asbestos concentration of ABS was 0.0048 f/cc (PCM) and 0.0042 f/cc (TEM) in KC, while it was 0.0137 f/cc (PCM) and 0.0125 f/cc (TEM) in SS. It was found that the average asbestos concentration of ABS in SS was statistically significantly higher than that of KC (p<0.01). The results of ELCRs by scenario in KC showed that the scenarios of bicycle, car, weed control, weed whacking, child playing in the dirt, and physical training fell within $1{\times}0^{-6}-1{\times}10^{-4}$, which is the acceptable range of ELCR. The scenarios of motorcycle, walker, digging, and field sweeping, however, exceeded the acceptable range. In SS, only the scenario of car fell within the acceptable range, while all of the other scenarios exceeded the acceptable range.

Price acceptability has become an important issue in the current fashion market. This study explored diverse factors that affect price acceptability (level of acceptable price and range of acceptable price). Stimuli photos of fashion products (i.e., bag, shoes, and jacket) were developed and used for online experiments with 3,000 female consumers. Important results included factors that affected the price acceptability of fashion products were price-quality relation, price concern, and product attribute perception. The results showed that female consumers depended more on price-quality relations, more positively perceived product attributes, and were less sensitive to price; in addition, they tended to have a higher level of acceptable price as well as a wider range of acceptable price for fashion products. These results were consistent across all experiments with different fashion items (i.e., bag, shoes, and jacket). Based on the results, factors that influence the price acceptability were revealed. Marketing practitioners need to more actively consider implying advertising strategies that emphasize the advancement of product attributes such as quality for highpriced products.

The concerns of wood vinegar increase with its various applications to food additive, functional drink, and in the sustainable farming. Chaff vinegar, a by-product of chaff charcoal which is produced by distilling smoke and having similar ingredients and efficacy with wood vinegar, contains harmful tar in the acceptable range and can be mass-produced. A chaff vinegar distiller, commercially mass-productive, was developed using a water cooling system. Initially distilled vinegar by the developed system contained little harmful tar in the acceptable range for the agricultural use and its acidity was about pH 3.2. Treatment of the chaff vinegar in the enhancing emergence test showed greater number of emerged seedlings, and vise-versa. Treatment of diluted in 100-holds showed 44.0% of emerged and 8.6% of not-emerged seedlings.

In order to rpovide proper SMT design criteria in a systematic way, a mathematical formulation has been developed to predict the configuration of the solder fillet formed between the gullwing type lead and rectangular pad. Effects of SMT design parameters such as the solder volume and pad dimension on the solder profile are investigated using the FEM that calculates the 3D configuration by minimizing the energy due to surface tension and gravity in the equilibrium state. Design criteria of QFP and SOP are illustrated by plotting the acceptable range of the solder volume with respect to the length and width ratios of the pad and lead. The results show that the acceptable design range increases with increase in the pad length and width. The pad length has more significant effects on design criteria compared with the pad width, and Bond number can be utilized to predict the joint quality.

Recently, many studies have been conducted to utilize the digital aerial photogrammetry method in the field of cadastral surveying. The representative models of digital cameras currently used for aerial photogrammetry are classified into line-type and convex-type cameras, so the representative models were selected and analyzed. The purpose of this study was to analyze whether the accuracy suggested by the cadastral survey enforcement rules was satisfied by comparing the orthogonal and ortho image performance. As a result, there were some representative false points that exceeded the acceptable range, but the results extracted from most of the images were shown to satisfy the acceptable range. Therefore, it can be said that the application of digital aerial photogrammetry to the cadastral field in the technical aspect has sufficient potential.

Korea has become an aged society according to the UN specifications. The number of the aged population will increase drastically, and the number of single aged people will also increase. Products used in our daily life are manufactured within the normal capabilities of people. Thus, aged people have encountering problems in using them. Numerous products are used in our daily lives. The purpose of this study is to find the acceptable torque for aged people to open the caps of processed food containers. Depending on the size and shape of the opening hand, hand operation has been classified into three categories. A total of one hundred and nine people participated in this study. Fifty nine people in the 20-30 year old range and fifty people in their 60-70's. Results of the study are as follows: 1) For all categories the acceptable cap torque data for the aged people are established. To satisfy 95% of the aged people, it was found that $74N{\cdot}cm$ for type A caps, and $141N{\cdot}cm$ for B type caps. and $214N{\cdot}cm$ for type C were the acceptable torque levels. 2) The appropriate level of torque for opening the cap was found to be 70% of the maximum torque for the aged people.(71.4% for type A. 71.4% for type B. 72.2% for type C). 3) Capabilities of the 70's drops sharply in function related to opening cap (maximum torque, gripping force, and wrist movement range). 4) Among aged subjects, 65.0% for type A, 42.0% for type B, and 68.8% for type C, had difficulties in opening the container caps.
