Recently, the interest in a garment that accentuates a fit and slender body continues to be highly desirable. Customers frequently want to wear a slim designed jacket that fits well, reflecting the trends of being young and slim. Accordingly, this research collected information on brands with ready-to-wear slim fit tailored jackets that target female customers in their 30s. By identifying the jacket pattern design and production state by brand, and evaluating the appearance when wearing the jacket, I was able to draw up the following conclusions. First, the fit highlights many problems because of the difference between the model size of brands that targeted domestic women in their 30s and the standard somatotype of them. This can be solved by considering the somatotype of women in their 30s when choosing the models. Second, the relative simplicity of the pattern should allow a slim fit tailored jacket to be produced that fits the front, back and side well. This would lead to the development of a jacket that would fit better as well as allowing for ease of movement. Similar to this, the model size of domestic brands changes frequently and customers prefer the size of a slim model instead of the size suitable for a target's somatotype. This results in a limit on the levels of satisfaction regarding brand targets for body types. Accordingly, it is hoped that this research will become the standard data for the development of a slim fit tailored jacket that will fit women in their 30s well.

The pattern of variations in cone sex ratio and pollen traits such as pollen number and size was examined for two years in populations of red pines In Korea. We evaluated; (1) the relationship between tree size and cone sex ratio, (2) the relationship between year and cone sex ratio, and (3) the relationship between cone sex ratio and pollen traits. Larger trees in height and circumference at breast height produced more male as well as female cones. However, cone sex ratio was independent of these plant sizes. Across the two populations, both female cone numbers per tree and male cone numbers per new shoot increased 2.2 and 1.2 times, respectively, in 1999 compared to 1998, while the yearly pattern of male cone-bearing shoots per tree differed significantly between populations. Thus, cone sex ratio varied significantly between years in one of the two populations. Pollen traits such as the number of pollen grains and diameter did not vary significantly among populations. Pollen diameter and grain numbers per male cone were significantly negatively correlated with the cone sex ratio in two populations and one population, respectively. Trees which stopped female cone production in the first year and those which produced female cones in both years differed in the cone sex ratio and pollen size in the second year. The long duration of one reproductive episode and the potential of masting in red pines emphasize the need to conduct long-term studies on the dynamics of cone production, cone sex ratio, and simultaneous changes in pollen traits in red pines.

This study provides basic research for developing dress forms of women's wear making. This study compared the average body size of Korean women by investigating the shape, composition and size of 417 dress forms for pattern making, sold at Korean and international online malls. The results showed that Korean brands produced torso-type and torso-crotch-type (94.13%), torso-type was the most dominant type made by Japanese Ki and French St (${\geq}80%$), and all US Al products were whole-body-type. The most common used internal filler of the dress forms was urethane for South Korean companies and paper for Japanese Ki and French St. In most cases, cotton was used for outer materials. Alternatively, linen and rayon were used as outer materials. Al did not indicate the materials used for filler and outer layers. Additionally, the sizing system of dress forms was commonly presented as a Numeric type. In addition to Numeric type, Ki presented body type + usage and Al used character type. When the dress form size for the average bust size of each age group was evaluated, waist measurements were smaller than the corresponding bust measurements. Dress form was presented in the KS interval and was compared with the $mean{\pm}1{\sigma}$ interval of each age group. The majority of the dress forms produced in South Korea were for body shapes in their 20s.

There's a way to recover unbalanced industrial structure between large size company (LEs) and small size company(SMEs). It's called middle size company (MEs) which can be the magic bullet for Korea to be more healthier than ever. but there are problems with MEs in Korea. Not only the number of MEs is too low compared to developed country's but also the status of amount of research developmental revenue, R&D concentration isn't that satisfied. That's why we need to focus on MEs which was out of center stage until now. Before discussing about how to foster MEs, we need to know what cause MEs makes weak. This research contains actual condition of R&D investment in MEs based on data from Korea information service. Also, survey data can help to know exact factor which make hard to invest research development. Expecially, this research give the answers that relation between the course of growth and concentration of R&D which was observed that has reciprocal relationship.

Various kinds of estimation methods have been developed for imputation of categorical missing data. They include category method, logistic regression, and association rule. In this study, we propose two fusions algorithms based on both neural network and voting scheme that combine the results of individual imputation methods. A Mont-Carlo simulation is used to compare the performance of these methods. Five factors used to simulate the missing data pattern are (1) input-output function, (2) data size, (3) noise of input-output function (4) proportion of missing data, and (5) pattern of missing data. Experimental study results indicate the following: when the data size is small and missing data proportion is large, modal category method, association rule, and neural network based fusion have better performances than the other methods. However, when the data size is small and correlation between input and missing output is strong, logistic regression and neural network barred fusion algorithm appear better than the others. When data size is large with low missing data proportion, a large noise, and strong correlation between input and missing output, neural networks based fusion algorithm turns out to be the best choice.

The study analyzes the lower-trunk sizes of 7-12 year old elementary school boys and compares sizes with boys, juniors, and men for analyzing and image fit. For the study, the data of SizeKorea (2004) was analyzed. Waist, hip, and the ratio of hip-thickness to hip-width were significantly different between age groups as well as between boys, juniors, and men. In the same height group, over 145cm boys had bigger waist than juniors and smaller waists than men. Therefore, the difference of waist size and the length of leg could cause the dissatisfaction of the pant fit when tall and plump boys chose a corresponding pants size to individual height or waist. The hip-thickness of body and pants patterns were compared in the analysis of the ease of hip-thickness. Tall and plump boys will feel discomfort in the crotch area because of the insufficiency of the hip-thickness of pants. Therefore, the amount of crotch extension of individual pants should be calculated by hip size instead of using the fixed amount. The reference sizes for discriminative pants for tall and plump boys were analyzed for a better fit.

In this study, we surveyed the current status and sizing system of the custom dress shirts sold through online shopping, compared with the sizing system of the ready-made dress shirts. We tried to collect the information needed to make the well fitted dress shirts for middle-aged men from this study. The 17 online custom dress shirt brands were selected and the sales type, sales price, design options and size options of each brand were analyzed. The sizing systems of online custom dress shirt brands were compared with the sizing system of the 10 ready made dress shirt brands. The result showed that online custom dress shirts brands offered a variety of design options and size options to meet the consumers' individuality, taste and demand for good fit. In the ready-made brands, all 10 brands were using the same size notation system. In the same size designation, the difference in product size among the ready-made brands showed a tendency to be smaller than the online custom brands. The online custom brands had the different size notation system among brands. The size notation, the number of size designation and the size interval were different for each brand. Also, in the online custom brands, the product size among brands differed from each other in the same size designation. Therefore, the standardized size information and sizing system for middle-aged men that could be used as criteria when making the product size and pattern design in online custom brands were needed.

The purpose of this research is to develop a basic pattern of corset look taking into consideration characteristics of human body and fit, by transforming 3 dimensional information obtained from draping of standard body type of women in their 20s, which constitute the biggest consumer group of corset look in Korea, on the basis of body shape of women best reflecting 3 dimensional characteristics. In order to develop a corset look pattern suitable for standard body type of women in their 20s, wear tests of A, B, and C types of patterns in terms of the bust in the standard body type that bust circumference 86.7cm and chest circumference 87.0cm were evaluated best. Taking into consideration above findings, fer the purpose of developing a corset look pattern having an excellent fit and reflecting characteristics of Korean women in their 20s with standard body type, a corset look pattern was designed with proper ease calculated by draping incorporated, and through alteration and complementation of such a pattern, a study pattern was produced. This study is expected to provide tips for standard body type women in their 20s with smaller bust circumference to choose clothing allowing for a better fit able to make up for weakness of their body, while presenting to clothing makers ways of designing and size-setting in terms of characteristics of body type of these consumers.

This study aimed to analyze adult men's body sizes and shapes and suggest size specifications to provide preliminary data to academia and industries. A total of 814 adult men aged 30-44 were selected from the 7th Size Korea data, and 55 direct upper body measurement and calculation items were analyzed using SPSS 25.0. In individual Individual differences, thickness, circumference, and width were high, and height and length were low. Height above the waist base line and shoulder dimension decreased in early 40s age group, while height below the waist base line declined as age increased. In addition, buttocks shape changes were found in early 40s age group. According to factor analysis, 'upper body and upper-extremity horizontal size', 'torso height and upper extremity length', 'shoulder dimension', 'upper body length' and 'shoulder angle' were derived. Using clustering analysis, four different body types were classified: i) big abdomen with flat chest, ii) slender with big, raised shoulders, iii) dwarfish with small, droopy shoulders, and iv) obese with large shoulders. 'Slender with big, raised shoulders' was a typical body shape among men aged 30-44. In older participants, the 'big abdomen with flat chest' ratio was low, while 'obese with large shoulders' was more common. This study proposed size specifications by body type considering the above characteristics.
