The purpose of this study is to figure out the information needed to improve the shape and size suitability of face-applied mask sheets. The study analyzed the shape of the mask sheet from the scanned images of 50 products of 37 domestic brands. In addition, each measurement of 42 mask sheets were compared and analyzed multilaterally with the 3D measurement dimensions of the faces of men and women in their 20s from the 6th SizeKorea data. Analysis on the shapes of mask sheets indicated that domestic commercial mask sheets are mainly made of single or dual sheets, with slits for enhancing fitness to the three-dimensional face. In the dimensional analysis of Korean men, women and mask sheets, most of the lengths of the mask sheets were significantly larger or smaller than the actual faces of men and women. The horizontal length and vertical length of the forehead above the eyes are significantly shorter, thereby requiring adjustments in the dimensions of this area. In order to improve the size suitability of the mask, it is necessary to adjust the dimensions of the problem area according to the research results as well as diversify the dimensions considering the target layer.

The object of this study lies on classifying the size, which is mostly favored in Korea where the wedding dress is usually regarded as an article for rent, and on suggesting the range of sleeve design and that of neck line of bodice. For that, I extracted the average size by analyzing and researching the standard size of actual bodice from real wedding dress manufacturing company. According to the result of the research I named the standard size of Korean wedding dress for rent as 'WM' which has the girth of 88cm and the waist measure of 69cm. Based on the size 'WM', I also named the size 'WS' which has the girth of 82cm with extra length of 6cm up and down and the waist measure of 64cm with extra length of 5cm, and the size 'WL' which has the girth of 94cm and the waist measure of 74cm with same extra length as the size 'WS'. The extra space for the inseam of the back is 3 inches for left and right for all sizes and the mark of body size is standardized as 'girth-waist measure'. After that, I suggested the design types of sleeves and neck line of bodice which defined as its size by classifying the bodice of wedding dress based on its size. Generally the neck line of the tank top style has the widest range of wearable size, and the high neck line and bateau neck line types have the narrowest range. And the sleeveless type has the widest range of wearable size while the raglan type has the narrowest one.

Resulting anthropometric data recently measured and cataloged through 5th national anthropometric survey that is called Size Korea is highly useful in clothing industries. This study aims at suggesting a statistical methodology for apparel sizing that reflects recent changes in Korean anthropometry and improves customer fitness. Based on previous research on body types such as triangular, rectangular, inverted body types, etc., factors that represent human sizes were extracted and then clustered into groups by their body types. These body type-based groups with respect to the factors obtained yielded a sizing system of which the interval of each factor is of equi-distance by their factor scores. However, each interval of the sizing system is non-linear in terms of individual anthropometric variables. The sizing system being proposed in this study was compared to that of KS K 0050 and had a broader coverage for the Korean population surveyed. The apparel sizing scheme is expected to improve customer fitness when applied to garment sizing and to provide more information on what percentage of population is included in each classification.

The QUAL2K has the same basic characteristics as the QUAL2E model, which has been widely used in stream water quality modeling; in QUAL2K, however, various functions are supplemented. The QUAL2Kw model uses a genetic algorithm(GA) for automatic calibration of QUAL2K, and it can search for optimum water quality parameters efficiently using the calculation results of the model. The QUAL2Kw model was applied to the Gangneung Namdaecheon River on the east side of the Korean Peninsula. Because of the effluents from the urban area, the middle and lower parts of the river are more polluted than the upper parts. Moreover, the hydraulic characteristics differ between the lower and upper parts of rivers. Thus, the river reaches were divided into seven parts, auto-calibration for the multiple reaches was performed using the function of the user-defined automatic calibration of the rates worksheets. Because GA parameters affect the optimal solution of the model, the impact of the GA parameters used in QUAL2Kw on the fitness of the model was analyzed. Sensitivity analysis of various factors, such as population size, crossover probability, crossover mode, strategy for mutation and elitism, mutation rate, and reproduction plan, were performed. Using the results of this sensitivity analysis, the optimum GA parameters were selected to achieve the best fitness value.
