The concectration and distribution of contaminants obtained from a contaminated land investigation or an environmental geochemistry survey constitutes the basis of a decision-making process on environmental policies or of scientific researches. As the quality of data determines the reliability of the result, the investigation plan should be adjusted according to the purpose of the investigation. In general, the effort to improve the data quality had been focused mainly on the QA/QC procedures in laboratories. The rapid progress of analytical instrument has also contributed toward improving the analytical precision to a sacrificable degree. Nevertheless, in many cases, it is not the analytical precision that needs improvement for the better precision of overall measurement process: it is rather during the sampling process in the field that is responsible for the poor precision. To assess the data quality on a measured value, ISO recommends to provide information on "measurement uncertainty" along with the measured value. The measurement uncertainty in an environmental measurement context can be explained as the statistical number that expresses the degree of the uncertainty stemming from the sampling and analytical procedures. There is a cost involved in order to improve the precision of sampling and analytical methods so as to decrease the degree of measurement uncertainty. The economical point of compromise in an investigation planning can be achieved when the allowable degree of uncertainty has been set before-hand. The investigation can then be planned accordingly not to exceed the uncertainty limit. Furthermore, if the measurement uncertainty estimated from the preliminary investigation can be separated into sampling and analytical uncertainties, it can be used as a criterion where the resources for the investigation should be allotted cost-effectively to reinforce the weakest link of the whole investigation process. This paper aims to present a method of estimating the level of measurement uncertainty of a measured contamination concentration at a site used as an example and to show how the estimated uncertainty can be applied to serve the particular purpose of an investigation.

파사드리거는 아웃리거 구조시스템에 rms거하는 것으로 구조물의 외곽에 설치되는 파사드리거는 구조물의 내부에 수직으로 설치된 가새골조로부터 분리되어 구조물의 외곽에 설치된다. 따라서 이 시스템은 중앙의 코아에 부착되는 아웃리거와는 달리 사재로 인한 내부 동선의 장애가 발생하지 않는 장점이 있다. 리거의 현재에 인접한 슬래브가 파사드리거와 가새골조 사이의 전단력을 전달하며 가새골조와 파사드리거를 지지하는 기둥 사이의 상호작용을 일으킨다. 이 논문에서는 등분포하중과 삼각분포하중, 그리고 구조물 상단에 집중하중이 작용하고 구조물의 외곽에 여러개의 파사드리거가 설치된 가새골조에 대한 근사해석방법을 제시하였으며, 구조모델들을 이용하여 MIDAS프로그램에 의한 결과와 비교하였고 만족할만한 결과를 얻었다. 본 연구에서 제시된 매트릭스 해석방법은 구조물 상단의 수평변위나 가새골조 하단의 전도모멘트와 같은 구조물의 거동에 대한 파사드리거의 영향을 신속하게 평가할 수 있으며 구조물 상단의 변위를 최소화할 수 있는 파사드리거의 최적위치 결정을 위해 유용하게 사용될 수 있을 것이다.

Gender selection is important in livestock industries; for example, female calves are required in the dairy industry. Sex-sorted semen is commonly used for the production of calves of the desired gender. However, assessment of the sex ratio of the sorted semen is tedious and expensive. In this study, a rapid, cost effective and reliable method for determining the sex ratio was developed using a multiplex real-time polymerase chain reaction (PCR) assay. In this assay, the X and Y chromosome-specific markers, i.e., bovine proteolipid protein (PLP) gene and sex-determining region Y (SRY) were simultaneously quantified in a single tube. The multiplex real-time PCR assay was shown to have high amplification efficiencies (97% to 99%) comparable to the separated-tube simplex real-time PCR assay. The results obtained from both assays were not significantly different (p>0.05). The multiplex assay was validated using reference DNA of known X ratio (10%, 50%, and 90%) as templates. The measured %X in semen samples were the same within 95% confidence intervals as the expected values, i.e., >90% in X-sorted semen, <10% in Y-sorted semen and close to 50% in the unsorted semen. The multiplex real-time PCR assay as shown in this study can thus be used to assess purity of sex-sorted semen.

The purpose of this study presents bra pattern using the 3D measurements of the upper body subject to women in their 30's. Brassieres available in the market are mostly designed for straight body shape and many women seem to have experienced bearing discomfort in a great extent as they grow older. Brassieres should be designed to cover diverse body types and the accurate measurement of body type and breast shape is needed to accomplish that. As for the study method, 3D human body types were analyzed with RapidForm 2006, and the upper-body types and breast shapes were statistically classified through technical statistics analysis, cluster analysis, t-test, variance analysis, and cross analysis. The wearing tests went through the comparison of the brassieres of three makers in the market and the experiment brassieres(first and second) and then the evaluations were made by the subjects, the outer appearance assessment by experts, and 3D measurements.

This study was conducted to investigate the attitude to various soy foods and to estimate dietary isoflavone intake among Korean adolescents. The survey was carried out by self-administered questionnaire with 800 middle and high school students residing in urban and rural areas and 714 questionnaires were collected: resulting in 89% response rate. The dietary isoflavone intake was estimated by food frequency questionnaire developed for rapid assessment of isoflavone intake. Soybean paste, soybean curd, soy milk, bean sprouts and dambuk were recognized as nutritious and healthy food in order. Dambuk got the lowest score in taste and flavor. Bean sprouts, soybean curd and soybean paste were recognized as familiar food in order. Stuffed rice in fried soybean curd got the highest score and Miso soup got the lowest in preference. More than 50% of the subjects consumed soybean paste stew/soup and soybean curd over twice per week and 12.3% of the subjects consumed soybean over once a day. The estimated daily intake of isoflavones ranged from 0 to 227 mg, and the mean daily isoflavone intake of the subjects was 28.1 mg (16.3 mg genistein and 12.0 mg daidzein) whereas the median value of isoflavone intake was 19.7 mg. There was statistically significant relationship among Kyung Gi Do, Chung cheung Do and Seoul residents in their intake of isoflavone. The highest monthly income group consumed isoflavone more than the other groups. These results suggest that Korean adolescent perceived the soybean dishes as high quality foods but they didn't take much because of difficulty to cook or less chance to eat. Nutrition education program is needed to enhance consuming soy foods for prevention of chronic diseases related to dietary isoflavone intake. More detailed information on easy cook method of soy food is also needed.

Purpose: The purpose of the study was to contribute to the prevention of musculoskeletal disorders (MSDs) in 119 emergency medical technicians (EMTs) by evaluating ergonomic risk factors of patient lifting work-postures. Methods: Four procedures were evaluated: using long back-board (LBB) on the sitting and standing main stretcher, using variable stretcher on the sitting and standing main stretcher. Wok-postures were assessed during training. Results: In using LBB on the sitting main stretcher, the OWAS-score was Mode:3 (Mean:2.30, Maximum:3), the REBA-score was Mode:9 (Mean:7.61, Maximum:11), requiring improvement soon. In using LBB on the standing main stretcher, the OWAS-score was Mode:3 (Mean:2.33, Maximum:3), requiring as soon as possible corrective action, the REBA-score was Mode:6 (Mean:5.44, Maximum:11), requiring improvement. In using variable stretcher on the sitting main stretcher, the OWAS-score was Mode:1 (Mean:1.85, Maximum:3), not requiring corrective action, the REBA-score was Mode:6 (Mean:6.78, Maximum:11), requiring improvement. In using variable stretcher on the standing main stretcher, the OWAS-score was Mode:3 (Mean:2.84, Maximum:3), requiring as soon as possible corrective action, the REBA-score was Mode:11 (Mean:9.38, Maximum:11), requiring immediate improvement. Conclusion: All four-procedures showed improvement in work-posture. Thereby, required attention and management in training, occupational health professionals should participate in change of lifting-method, and programs aimed at preventing MSDs should be developed and implemented in fire-academy and fire-station.
