The objects of this experiment are to find out the local variation of the Dendrolimus Spectabilis Butler, of which sample was first collecteted 15 bodies of male and 35 bodies of female adult at Suwon area. the wing veins and the scale shape have been observed through the microscope (100) and the scale size (from the bottom of the scale to the top of the lobe) has also been measured by the micrometer. The results of this experiment are as follows: 1. There is nodifference between the venation of the male body and that of the female body. Also we can not find any differences between the right and the left wing, and between each body. The fore wings consit of 13 longitudinal veins and the only one "V" shape cross vein which is between the 5th and 6th vein. The hind wings consist of 9 longitudinal veins and the only one "V" shape cross vein which is mentioned above. 2. The scale types are divided into 4 Groups in its shape. (A) The scales of I Group are short and the lower parts of them almost look like a circle, having a small projection at their bottom. The upper parts of them have 2 or 10 lobes. We can find the lobes with fine hairs or the lobes without them at the top of the scales. (B) The scales of II Group are longer than that of I Group. The shape of the lower parts of the scales is similar to that of I Group. The upper parts of the scales have 2 or 10 lobes. (C) The scales of III Group are long and almost alike in a long wedgeshape. The upper parts of the scales have 2 Or IO lobes and we can find long fine hairs at the top of each lobe. (D) The scales of IV Group are long and the shape of the lower parts of the scales is similar to that of III Group. The lobes are short and not sharp. We can find 2 or 9 lobes. 3. The scales of I Group and II Group are distributed on the whole surface except on the outer margin. The most scales of III Group are distributed on the wing base. The scales of IV Group are distributed on the outer margin only. The scales with 4 or 5 lobes are most widely distributed not considering their Group or distributing parts. 4. In I Group the variation of the scale length become gradually greater as the number of the lobes are increasing. In II, III, IV Group, however, the variation of the scale length is in direct opposition to the above mentioned. The variation of the scale width becomes pretty small in any Groups and the scale width become wider as the number of the lobes are increasing. 5. The source of the wing colouration is pigmnetal colour, and the wing colouration is expressed by the amount of brown and white scales.

This study was aimed at giving help to the people intending to change hair fashion feeling for making their own hair style design and also providing the academic guide line to the cosmetic circles for developing new hair design and promoting sales by producing hair styles following the results from the statistical analysis based on the theoretical study on the face contour groups & hair fashion feeling groups. The researching methods were composed of following 3 steps ; prior theoretical research, statistical analysis, and hair style production. At first, the prior theoretical research was accomplished by analysis of literatures, magazines and internet sites about face contour, total & hair fashion feelings, hair style productions. Second, the prior statistical analysis were done about hairstyle images & their charateristics based on fashion feelings, and characteristics of fashion feeling group. And the third, hair style productions were done coordinated by face contours(oval, circle, long, square, reverse triangle) and hair fashion feelings(natural, sexy, sophisticate, ethnic, romantic pretty, elegance, sporty, avant garde) following the statistical results. But owing to the limitations to change hair length and color, these changes are modified by wigs and photoshop 7.0 program. So we could know there was no confirmed hair fashion feeling of one's best, but one could change one's hair fashion feeling and express one's beauty if one could adjust one's hair styles properly to one's face contour. This study would be very helpful to the people trying to change their own hair fashion feeling and be useful to the cosmetic circles for developing new design and promoting sales by comprehending hair design market and also be valuable to develop the methodology of 3 step research.

A finite element procedure which can trace plastic collapse behavior of plane frame structures under small and large deformation is presented. The member is assumed to be prismatic and straight, and has the rectangular or I cross section. For the elasto-plastic analysis, the concept of plastic hinge is introduced and the incremental displacement method is applied. The limit state condition of the plastic hinge is considered under the combined condition of a bending moment and an axial force. Numerical examples are presented in order to demonstrate the validity and efficiency of the proposed procedure.

With the increasing interest on K-fashion all over the world, it's the important time to create the items which can express the unique identity of Korea for promoting the globalization of Korean fashion. Accordingly, this study aims to suggest the modern applicability of traditional patterns by designing the bags using the Dancheong patterns(traditional multi-colored decorative painting) which can effectively express Korean images in a variety of shapes and definite visual features and then expand the scope of fashion items. To this end, this study concentrated on expressing the Dancheong patterns to fit to the modern fashion trends by re-interpreting them. The bag was designed using the laser cutting technique, without weaving or digital printing, to imbue the technical emotion and 3D effect to the patterns. In accordance with the analysis results, the features of patterns could be delicately expressed around the shaping and structuring method in terms of the design, and the scope of design for leather goods could be expanded using the laser cutting in technical aspects. For the industrial aspects, it is required to develop differentiated goods expressing the unique emotion of the Korean for globalization of Korean design.

The static nonlinear analysis of offshore pipeline is carried out by the finite element method. The governing equilibrium equation are derived by the principle of minimum potential energy and the modified Newton-Raphson procedure is used to solve the system of nonlinear algebraic equation. Geometrically nonlinear beam elements and spring elements are utilized to model the pipeline, stinger, pipe supports and seabed simultaneously. The beam element developed can be used to model redundant structures. It provides for both the torsional deformation and elongation of pipeline, and permits the use of different physical properties in each principal direction. The validity of this method is investigated by comparing the results with these obtained by other methods.

The melting phenomenal of the horizontal cylindrical ice-bar submerged in water are experimentally investigated for the temperature range from 2.5.deg. C to 15.deg. C. The shapes of the melting ice-bar are recorded by the Photo-elasticity Apparatus with modification of the test section. The shadowgraphs of the melting ice-bar show that water adjacent to the bar flows upward for the temperature range from 2.5.deg. C to 5.6.deg. C while above the temperature of 5.6.deg. C the flow is downward direction. The local and average Nusselt numbers become minimum at 5.6.deg. C which is considered as a critical temperature and the Nusselt numbers increase as temperature difference from the critical temperature increase.

A morphological study on the immature and adult stages of Anagrus incarnatus Haliday was carried out under laboratory condition at 25$\pm$1$^{\circ}C$. The egg is sausage-shaped with a long slender pedicel. The first instar is a bag-shaped larva. The second instar larval form of A. incarnatus is similar to he "histriobdellid" stage. The antenna has 9 and 13 segments of the female and male, respectively. The first funicular segment of the female's antenna is very short, subspherical or globular type and the third funicular segment with one sensory ridge is longer than the forth. The forewing of A. incarnatus has 8-9 rows of discal hairs providing no bare space at the broadest part. The length of ovarian eggs, egg, 1st instar, and 2nd instar of A. incarnatus is 0.165, 0.215, 0.290, and 0.535 mm, respectively, and the width of each stages is 0.025, 0.057, 0.082, and 0.110 mm, respectively. The developmental periods for egg, 1st instar, 2nd instar, prepupa, and pupal stage are about 1, 1, 4, 1, 5-6 days, respectively.pectively.

This study aims to develop an economical precast hollow concrete column with high constructability which consists of only splice sleeve and general reinforcing bar without using PC tendons in order to reduce the construction period and cost. With this purpose, this study performed the finite element analysis and tension test by using some variables such as length of sleeve, diameter of rebar and curing method for suggesting a grouting type splice sleeve which is a new type joint rebar and developing an optimized splice sleeve. As a result, the analysis on the tension performance of splice sleeve did not show any destruction caused by pull-out in reinforcing bar but it only occurred destruction of tension bar or bolt shear rupture from the mechanical defect of sleeve. Therefore, the experiment showed high performance in tension of the suggested splice sleeve and verified the application of precast hollow concrete column.

This study investigated the architectural expression of Taekpungdang(澤風堂, The Pond and Wind House) built by the Neo-Confucianist Taekdang Lee Sik(澤堂 李植, 1584~1647) from the perspective of the symbolic system of the Zhōuyì(『周易』, Classic of Changes). This study examined the historical context, personal history, and construction process of Taekpungdang at the time of its creation through his collection of writings, the Taekdanggip(澤堂集). The study also estimated the original form of Taekpungdang through field surveys and historical evidence. In addition, the architectural principles and architectural expressions inherent in the Taekpungdang were derived based on the symbolic system of "taekpungdaegwa"(澤風大過) which is Lee Sik's divination and one of the 64 trigrams in the Zhōuyì. Lee Sik, who was knowledgeable in the Zhōuyì, used divination to cope with the chaotic political situation and his own misfortunes. Accordingly, He determined the direction of his life and planned the surrounding environment, architectural structure, and form of Taekpungdang based on the rules and meanings of his divination system. He embodied the architectural space of Taekpungdang with the concept of time and space inherent in the divination of "daegwa",(大過, great exceeding). In addition, he expressed the principle of the generation of palgue,(八卦, the eight trigrams for divination) and the principle of the co-prosperity of ohaeng(五行, the five elements) through the composition of walls and windows of the house. The images of Taekpungdaegwae, which are dongyo(棟撓 wood submerged in the pond) and taekmyeolmok(澤滅木, shaking pillars), were manifested in the form of buildings. Therefore, Taekpungdang can be considered a remarkable example of a building designed through the thorough utilization of the Zhōuyì divination system.

View of Lee Je-ma's "Hyung Sang" is one of the methods of classification of Constitution. In this study, I studied the "Hyung Sang" as medical histologically, and get the results as follow; 1. "The book of changes" is classified to the sciences of divination of "Sang-Soo", which is consisted with "Sang (image)" and "Soo (number)", and "Wae-Ri", which explained the meaning of a divination sign as "nature" or virtue of divination sign. 2. Lee Je-ma is accepted the concepts of science of divination of "Wae-Ri" based on Confucianism in the discription of "The book of changes". And also he established the new "Sasang Constitutional Medicine" theory based on the "Joung-Young". 3. "The book of changes" is discribed phenomena as "Sang" and "Soo" involving "Three elements", which are heaven, earth, and individual, and "Yin-Yang". Lee Je-ma accepted the concept of "Sang" in science of divination of "Sang-Soo" and established the "Four elements", which are affairs, mind, body, and objects, constituting "Three elements". 4. In the method of "Sasang" type classifying, Lee Je-ma used "Four elements", which attach importance to structure and function of human body rather than "Yin-Yang", which explain relatively.
