This study provides basic data that are helpful to prepare a sizing system for dress shirts that improves the wearer's size fitness. The 16 different parts of the dress shirts were measured for 24 pieces of dress shirts with three kinds of size (95, 100 and 105) among the eight different brands on the market. The measurement sizes of the dress shirts analyzed the accuracy of the size information, size classification by size designation, and differences of size by brand. The results of the study were: 1. The size information of dress shirts differed from customer demand. 2. The size increments between size designations differed from each other even though measurement sizes of the dress shirts increased as the size designation increase. 3. Measurement sizes of the dress shirts were different between brands even for dress shirts of the same size designation. It is necessary that manufacturers secure an accurate and standardized sizing system and provide accurate information for the measurement sizes of dress shirts on an online shopping mall.

The Operation of high speed train in year 2004 bring about a great change in railroad industry. Especially in railroad construction field we have acquired great Know-how. And up to now we are building up operation skills. But the high speed train system are totally imported, so it is necessary to investigate some of the equipment based on our own environment. In case of Toughened Glass Stem Insulator, we don't have any application case in domestic and limited in abroad. So there must be some characteristic estimation. The estimation was made in three different ways. First electrical field cause, Second physical field cause and finally in circumstance cause. In Electrical field cause, amplitude and number of time for abnormal peak voltage data are collected. And in physical field cause, amplitude and trend of vibration in to the insulator are examined. And I circumstance cause, possibility of flying gravel and ice clod are investigated. Through this basic data suitability for Toughened Glass Stem Insulator using in domestic will be accumulated.

Thioctic acid is a vitamin-like antioxidant which is prepared as tablets and injection. The Korean Pharmacopoeia (KP XI) contains monograph for the quality control of raw thioctic acid using ultra-violet visible spectrophotometry and its formulations using high performance liquid chromatography (HPLC). In British Pharmacopoeia 2013 (BP2013), another HPLC method is used for the assay test of thioctic acid material. For the international harmonization, we present an HPLC method for quantitation of thioctic acid in both raw material and tablets. Method validation was performed to determine linearity, precision, accuracy, system suitability, and robustness. The linearity of calibration curves in the desired concentration range was high ($r^2=0.9995$), while the RSDs for intra- and inter-day precision were 0.93 ~ 1.26 % and 1.40 ~ 1.76 %, respectively. Accuracies ranged from 98.13-100.00 %. Since the system suitability, intermediate-precision and robustness of the assay were satisfactory, this method will be a valuable addition to the Korean Pharmacopoeia (KP XI).

To build up the green roofs, it must not adverse effect to durability and structural safety. That is conducted by safety system which consist of waterproofing to form basically, root barrier to protect the waterproofing. The reason why root barrier form is to protect the penetration force of root growth and the root could penetrate concrete surface, move inward so far. It may cause shorten the life span on concrete structure. For this problem, government constantly demand the solution to form the root barrier for waterproofing and concrete structure before the building is service. However, the technical action is not fully prepared. Therefore, in this study, we would like to suggest the workability and suitability of the copper plate to solve not only the side of waterproofing but also root barrier for green roof system and exhibit the mechanism for root penetration resistance and corrosion resistance.

The purpose of this study was to provide basic information on the propriety of the ready to wear garment sizes of Tween Generation(ages from 5th grade to 8th grade) who has different clothing preferences in color, styles, and design and also different body sizes and shapes from younger and older students. The objectives of the study were to ascertain (a) the body figure changes occurring during Tween Generation; (b) the coverage of manufactures'garment sizes. The body measurements of elementary school students(5th & 6th grades) and junior high school students(7th & 8th grades) provide the basic statistics for this study. The mean differences of each size within each figure type are compared by using t-teats. The differences in various manufacturers'apparel sizing and figure size are investigated. Also the body measurements and the apparel sizes of the manufacturers are compared in order to evaluate the suitability of the garment size. Results indicate that the body type factors are different in each age group. And manufactures'sizes come out to be much smaller than the actual body measurements. Young casual wear can cover junior high school students satisfactorily but for elementary school students, because of low drop-value, the overall satisfaction with filling is low.

본 연구에서는 토지적성평가 평가결과의 정확성을 향상시킬 수 있는 방안을 제시하였다. 이를 위해 지표값 측정 및 임계치 설정을 중심으로 현 제도에서 적용하고 있는 평가방법과 이를 개선할 수 있는 방안을 검토하고, 사례지역을 대상으로 두 가지 방법을 적용함으로써 기존의 방법에 비해 지니는 효과를 파악하였다. 구체적인 분석과정은 1) 공간적 입지특성에 대한 거리측정시 저항을 고려한 분석, 2) 보전적성값 산정시 물리적 특성지표에 적용되는 귀속도 함수의 임계치 설정에 따른 평가결과를 측정하였다. 평가결과 첫째, 저항을 고려한 측정방법이 단순한 직선거리에 의한 방법에 비해 하천이나 임야 등 접근성이 떨어지는 지역적 특성을 보다 잘 반영하고 있는 것으로 나타났다. 둘째, 대상지역의 최고값을 최대임계치로 설정하는 현재의 방법이 지표의 측정값 분포를 고려한 임계치 설정 때보다 상대적으로 평가절하된 점수값을 도출할 수 있음을 예측할 수 있었다. 마지막으로 인공위성영상자료를 평가결과에 중첩시켜 보았을 때 본 연구의 방법에 의한 적성등급이 현황과 보다 잘 부합하는 것으로 나타났다. 본 연구에서 제시한 평가방법은 토지적성평가 결과의 정확성을 향상시켜 준다는 점에서 의의가 크다. 더불어 그간 제도의 시행과정에서 나타난 문제점--평가단위의 문제, 평가절차상의 문제, 기초자료 정비의 문제 등--이 보완된다면 국토 및 도시정책 수립시 이를 효과적으로 지원할 수 있는 공간의사결정지원체계(SDSS)로서도 활용될 수 있을 것이다.

This paper discusses a methodology where an integrated modelling framework is used to quantify the risk derived from anthropic activities on habitats and species. To achieve this purpose, a tool comprising the Delft3D and HABITAT model, was applied in the Yeongsan river. Delft3D effectively simulated the operational condition and flow of weirs in river. In accuracy evaluation of the Delft3D-FLOW, the Bias, Pbias, Mean Absolute Error (MAE), Nash-Sutcliffe Efficiency (NSE), and Index of Agreement (IOA) were used, and the result was evaluated as grade above 'Satisfactory'. The HABITAT calculated Habitat Suitability Value (HSV) for the following eight species: mammal, fish, aquatic plant, and benthic macroinvertebrate. An Area was defined as a suitable habitat if the HSV was larger than 0.5. HABITAT was judged accurately by measuring the Correct Classification rate (CCR) and the area under the ROC curve (AUC). For benthic macroinvertebrate, the CCR and AUC were 77% and 0.834, respectively, at thresholds of 0.017 and 4 inds/m² for HSV and individuals per unit area. This meant that the HABITAT model accurately predicted the appearance of the benthic macroinvertebrates by approximately 77% and that the probability of false alarms was also very low. As a result of evaluating the suitability of habitats, in the Yeongsan river, if the annual "lowest level" (Seungchon weir: 2.5 EL.m/ Juksan weir: -1.35 EL.m) was maintained, the average habitat improvement effect of 6.5%P compared to the 'reference' scenario was predicted. Consequently, it was demonstrated that the integrated modelling framework for habitat suitability assessment is able to support the remedy aquatic ecological management.
