The purpose of this study is to find the relationship between women's shoes wearing trait and their foot shape. 203 women in their twenties were participated in the experiment. The subjects' feet were measured with a 3D foot scanner and their foot shapes were classified into five types by factor analysis and cluster analysis in the previous study. In addition to the five foot types, three foot types classified by foot index were also utilized for this study. This study analyzed the trait of their shoe wearing and the areas of discomfort on the foot when they wore shoes. The results of the experiment show that the size of shoe size-foot size mismatching and the foot areas of discomfort wearing shoes were differentiate by foot types. It shows that the subjects with long foot, wide fore foot shape, or fore foot angle deformity wore larger size shoes than their foot size. The foot areas of discomfort with wearing shoes were different according to the foot types. Subjects with wide fore foot shape or fore foot angle deformity had discomfort at the front shoe area. The subjects with straight toes had the least discomfort. The foot discomfort areas differentiated according to foot index type. The foot types with wide ball width experienced discomfort at the front of the ball and the top of the foot.

This study is for research of relationship between shoes wearing by adult woman and foot type. The research was made through questionnaire sheets of general matters (age, body weight, height & occupation) and shoes wearing status (hill height, toe shape, wearing time) of 216 adult women reside in the metropolitan zone and the foot type was classified from foot measurement and the relationship between shoes wearing and foot type was analyzed. According to the result of analysis it is as follows : 1) In the shoes type prefer for they prefer for lower hill as more ages and were preferring shoes with higher hill as the taller women. 2) The instep height is lower and medial foot angle was increased as their ages are more. Majority of foot type was appeared with standard type and the broad type was indicated more by age of 20s. The classification by toe the square type was indicated by majority and in the age of 30-40s the egyptian type was more 3) As the age and weight get increased he height of arch become lower and indicated to transit to flat-foot. That is to say they prefer for round toe in case of fiat-foot, and for square toe in case of normal and, choice of shoe toe shape it indicated by more impact by the height of arch rather than toe length.

The purpose of this study was to analyze the kinematical variables involved in two types of service motion in tennis pinpoint and platform stance, to find the fastest serving method. Seven skilled high school tennis players participated, and the kinematics were recorded by the Vicon motion analysis system. For the gathering and analysis of the data workstation, bodybuilder and polygon were used. During the back swing for the pinpoint stance, as the back leg moves forward the COM and the racquet moves more, thus taking 0.04 seconds longer than the platform stance. The body of the subject takes a bow-shape as the subject's foot moves back and their hip moves forward. This movement enables the subject to create more power during the backswing to impact. It also increases the spread of the COM racquet and the serve speed is increase. As there is no forward movement of the foot during the backswing of the platform stance, the COM and the racquet move less and thus the time required is shorter than that for the pinpoint stance by 0.04seconds. Similarly, the time spent creating the power for the serve is shortened, the COM racquet is narrower and the speed is lessened. However, the advantage of this serve is that it increases the stability.

Under representative democracy, members of the National Assembly exercise their authority to propose, enact, and revise bills on behalf of the people, and the legislation of such lawmakers has a great impact on individuals and society. There exist criticisms that the quality of legislator-sponsored bills has not improved while the number of them has been expanding recently. This study examines the type, productivity, and efficiency of legislation in the 17~19th National Assembly, and empirical analysis is conducted on how the lawmaker's legislations respond to election-related variables such as voter turnout and election competition. The results show that legislator-sponsored bills are mainly produced in the area of governance, finance, macroeconomic policy, social welfare, and health. The number of legislator's proposals increases, while the passing rate decreases, and the processing period extends. Constituents' participation in voting has been shown to enhance legislative efficiency. Based on the results, the paper emphasizes the enhancement of transparency in the legislative process, the improvement of the people's political knowledge, and the revitalization of election functions for the improvement of parliamentary legislation.

The shoe last which is the framework for the shoemaking is intensively combined with the 3D data and technologies. International shoe companies have already commercialized 3D printing technology in producing the shoe, but domestic shoe companies are still in their early stages. This study used the 3D scanning, 3D modeling and 3D printing of the high-technology to make the shoe last. This 3D producing processes should be helpful in building competitiveness in domestic shoe industry. The 3D foot scanning data of men in 30s(n=200) were collected in SizeKorea(2010). The basic statistics, factor and cluster analysis were performed. They were categorized in 3 groups by 3D foot measurement data, and the standard models were selected in each group. The cross sections in XY, YZ and XZ planes sliced from 3D scan data of the standard model were used in the sketches of the 3D shoe last modeling. The 3D shoe last was modeled by Solidworks CAD and printed by MakerBot Replicator2; a desktop 3D printer. This research showed the potential for utilization of 3D printing technology in the domestic shoe industry. The 3D producing process; 3D scanning, 3D modeling and 3D printing is expected to utilized widely in the fashion industry within the nearest future.

The influence of the 2-(4-(6-chloro-2-benzoxazolyloxy)phenoxy)-N-phenyl- propionamide derivatives on the herbicide activities against rice plant with pre-emergence and post-emergence in down land were examined and the structure activity relationship (SAR) were analyzed by Free-Wilson and Hansch method. In pre-emergence, the SAR approach is shown that the optimal, $({\pi})_{opt}=0.91$, hydrophobicity with electron donating effect of the ortho substituted mono substituents and 2,3,4-substituted three substituents were found to be contribute the herbicidal activity. Whereas, in post-emergence, the optimal, ({\pi})_{opt}=0.50$, hydrophobicity with electron withdrawing effect of meta substituted mono subsituents and 2,3-substituted two substituents were found to be contribute the herbicide activity. The herbicide activities with post-emergence more increase than that of pre-emergence. It is assumed from the SAR equations that the 2-methyl-3-methoxy-4-cyano group substituent is selected as the most lowest herbicide activity against rice plant with post-emergence in green house. The hydrolysis reaction was proceeded through nucleophilic addition-elimination (Ad_{Nu-E})$ with the orbital control between LUMO of substrate and HOMO of water molecule. And molecular electrostatic potential (MEP) of none (H) substituent was discussed.
