The aim of this study is provide fundamental data on the glove size and pattern-making. The study was conducted targeting 60 men and 271 women whose age were within the limits 18-35 in Seoul and the neighboring districts. A total of 90 features in the right hand wew used for the anthropometric measurement and analysis using anthropometry and photometry. The result show that there was a difference between men and women' hand. And the result of correlation analysis between hand factors, length factor related to length and depth factors, breadth factor related to breadth and circumference factors. The sailing glove size in Korea was not suitable to Index finger circumference at 1st Phalanx and Middle finger length.

Digital shearography, a speckle pattern method is based on the superposition of two laterally sheared images. Therefore, object points which are positioned in some distance from each other are superposed in the image plane. This shearography, one of NDT methods without contact, is able to inspect defects in pipelines and pressure vessels that are used in nuclear power plants. This is can inspect whole fields and has a low sensitivity to environmental noise. Because optical setting is very simple, it has a little exhaustion of time, cost and man power. And also it can find a defect position through real time monitoring of a part. This paper, finds out the relationship among shearing quantity image quality and defect size with this method.

In this paper, an efficient switching pattern to equalize the size of transformer is proposed for a multi-level inverter employing cascaded transformers. It is based on the prior selected harmonic elimination PWM(SHEPWM) method. Because the maximum magnetic flux imposed on each transformer becomes exactly equal each to each, all transformers can be designed with the same size regardless of their position. Therefore, identical full-bridge inverter units can be utilized, thus improving modularity and manufacturability. The fundamental idea of the proposed switching pattern is illustrated and the analyzed theoretically. The validity of the proposed switching strategy is verified by experimental results.

For a pattern to be a scientific and reasonable drafting method. it should be based on the human body, have fewer measuring items, be easy to learn, and be able to make good-looking clothing that fits many people. Therefore, the height, foot length and circle radius in the Durumagi drafted in this study examined to improved the drafting method for Korean Durumagi. As a result, a pattern drafting method was developed in which Moo, Gutsup, Ansup and length of clothing were naturally derived according to the size of individuals.

1. For the purpose of making the basic pattern construction 100 girls attending the Seoul National University College of Home Economics were measured in finding of body size and coefficient of correlation which would be used as one basis of this study. 2. Coefficient of correlation of each body part based on the breast width was shown as follows; Correlation coefficients of bust to waist and hip were high and those of bust to shoulder width, neck height, back width, and breast width were low. None of that was found between bust and back length. It was not recognized so scientific to adjust the basic pattern construction with figures proportioned by those of neck, shoulder width, breast width, and back width. 3. The method of basic pattern construction obtained by this research has been demonstrated in direct wearing since 1967. It is believed that the result will contribute a great benefit in teaching clothing as well as in mass production industry of ready-made garments.

This study aimed at providing basis data to understand homemanagement by patterning of the life styles of housewives and by analysing the disposition of homemanagement behavior and characterstics of the behavior pattern to the difference of the life style patterns of housewives. The result can be summarized as follows: 1. By utilizing factor analysis and cluster analysis, the life style types of housewives were classified into 4 types, namely, self-fulness type (28.4%), negative stagnation type (22.7%), fashion-convenience type (23.3%), innovation-urging type (25.6%). 2. The life style types of housewives which were classified, differed significantly according to all of the demographic variables except family size variable. 3. The disposition of homemanagement behavior which were classified into inner-directed type and other-directed type, differed significantly according to the husband's age variable. 4. The patterns of homemanagement behavior which were classified into market pattern and service pattern, differed significantly according to the all of the demographic variables. 5. The disposition and the pattern of homemanagement behavior differed significantly according to the life style types of housewives.

We consider the irrational part of the basic pattern drafting of the Geo-Ko-ri so that we want to design it more scientically. So there are problems which is found after we considered with comparison about the existingly basic pattern drafting of Geo-go-ri. (1) there is a difference between the practical and Calculation. (2) The part of the curved line was mad indistinctly There is a difference betweence the calculating expression and calculating value. (4) There are some parts which lack objectivity about the reference size. (5) The calculating method of Collar-width and Neck-Nidth are not formative and rational. These are items that we must consider and study further. Especially if we can make up of the scientific form in consideration of the formativeness focused on "git" I think it will make a great contribution to not only the standardization of the basic pattern of Geo-go-ri and the use of the use of education but also the manufacture of individual clothing the production by Auto CAD.

FRC(Frame Rate Control) has been applied to the monitor and TV product as part of cost-saving in many flat panel display manufacturers. As FRC can represent the same number of gray scale level with bits of a smaller amount than bits of the input image data, it is widely used. However, FRC causes visual artifacts by using repeatedly pre-designed the FRC unit size of block pattern in display devices. Therefore, this paper analyzes the cause of the visual artifacts. And in order to improve them, it proposed the pattern arrangement of FRC unit blocks through frame rolling method as analytic solution for the first time. So, we could embody causes of FRC noise. Using the proposed structure, more robust pattern to FRC noise will be designed.

Variable range of focal length of Moiré lens is designed to change the phase pattern, which is varifocal lens system using two thin layers with Moiré pattern and suitable to applied to AR/VR system because of the relatively simple structure, large aperture size, and wide variable range. We analyze the change of focal length region according to the phase pattern and verify the design to make the prototype patterns using DOE.
