The purpose of this study is to find out the image according to formative properties of hat and garment in the fashion collection. For the study, the 96 stimuli found frequently in fashion collection from the S/S season of 1998 to the F/W season of 2004 were selected. Sets of stimulus and response scales (7 point semantic) were used as experimental materials. The stimuli were 96 pictures with the types of hat(4), the lengths of hair(3), the types of garment(3), the relations between the color of garment and hat(4), and the materials(4) and patterns of garment(2). The subjects were 415 women college students majoring fashion design related fields and living in Seoul and Gyeongsangnam-do. As statistical methods for data analysis, Factor Analysis, ANOVA test, and LSD test were used. The items of the adjectives were classified into 5 image dimensions; attractiveness, gracefulness, concentration, cuteness, and hardness and softness. Among these factors, each dimensional image was affected by formative properties of hat and garment. The image of a hat-wearer was perceived differently according to the hair style and the formative properties of hat and garment even if the type of hat was same.

The spot welded sections of automobiles (hat and double hat shaped sections) absorb most of the energy in a front-end collision. The target of this paper is to analyze the energy absorbing capacity of the structure against the front-end collision, and to obtain useful information for designing stage. Changed the spot welded pitches on the flanges, the hat and double hat shaped section members were tested on the axial collapse loads at various impact velocities. It was expected that para-closed sections would show collapse characteristics which be quite different from those of perfectly closed sections. Hat shaped section members were tested at the impact collapse velocities of 4.72m/sec, 6.54m/sec and 7.1m/sec and double hat shaped section members were tested at the impact collapse velocities of 6.54m/sec, 7.1 m/sec and 7.27m/sec.

This study aims to suggest basic data for the production of hats for aged women. The subjects were 151 females who are 60 years old or above and live in Busan. Their hat-wearing reality was inquired and their head parts were measured, which led to the following conclusion: 1. Results of Hat-Wearing Reality Inquiry 64.9% answered they are unsatisfied with the size system of the available hats at present, implying the necessity for improving the current dimension system. 92.7% responded hat dimensions need to be subdivided, while 97.4% were for the necessity of hat size system. 74.8% expressed their will to buy ordered hats because they can find the hats of right sizes and designs. 2. Results of Head-Part Measurement Experiments According to head-part measurement, head circumference A was 53.26cm, head circumference B 54.19cm, and head circumference C 57.69cm on the average. Cluster analysis revealed three types. Type 1 (24%) with small head length and circumference is the smallest head with a wide upper part. Type 2 (33%) has long head height, short bitragion arc A, and thick head breadth. Type 3 (43%), owing to big head circumference and length as well as high values in vertical items. Considering head circumference B (HCB) and bitragion arc A (BAA), a new hat size system of 3 sizes (HCB: BAA) was chosen: S (52cm: 29cm), M (53-55cm: 30cm), and L (56-57cm: 31cm).

Front-side members are structures with the greatest energy absorbing capability in a front-end collision of vehicles. This paper was performed to analyze initial collapse characteristics of spot welded hat and double hat-shaped section members, which are basic shape of side members, on the shift of flange weld pitches. The impact collapse tests were carried out by using home-made vertical air compression impact testing machine, and impact velocity of hat-shaped section members is 4.17m/sec and that of double hat-shaped section members is 6.54m/sec. In impact collapse tests, the collapsed length of hat-shaped section members was about 45mm and that of double hat-shaped section members was about 50mm. In consideration of these condition, axial static collapse tests(0.00017m/sec) of hat and double hat-shaped section members were carried out by using UTM which was limited displacement, about 50mm. As the experimental results, to obtain the best initial collapse characteristics, it is important that stiffness of vehicle members increases as section shapes change and the progressively folding mode induces by flange welding pitch.

The purpose of this study was to provide some preliminary results on application of 3D scan data of head shapes to the hat design and pattern-making. This paper defined necessary measurement items and concepts in 3-dimensional images of head shapes. And also it presented the methodology to pattern-making of 6-piece crown hat based on 3D data. It used the data of Size Korea to pick up and choose a head shape model with the average head size of Korean women in their twenties. Main results were: 1. The 3D scan data of head shape was better than the 1 dimensional measurement data. Because I could establish a hat pattern-making theory by the 3D scan data of head. 2. The 3D scan data provided the basis for conceptualization of basic measurement points and items for a better fit of hats as well as the definition of the basic hat circumference. 3. This presented a methodology for analyzing out head shape by 3D scan data, and allowed the derivation of the basic hat circumference from the maximum head circumference. 4. As the 6-piece Crown cloche hat made by this method fitted the head shape model perfectly, this methodology could suggest potential applicability to various hat design.

Non-alcoholic fatty liver disease (NAFLD) is caused by chronic lipid accumulation due to dysregulation of lipid metabolism in the liver, and it is associated with various human diseases such as obesity, dyslipidemia, hypertension, and diabetes. Histone acetylation is a representative epigenetic mechanism regulated by histone acetyltransferases (HATs) and deacetylases. We observed that tartary buckwheat sprout (TBS) suppressed lipid accumulation in HepG2 cells through its anti-HAT activity. We showed that TBS was a novel HAT inhibitor with specificity for the major HAT enzyme p300. Importantly, TBS reduced acetylation of total and histone proteins, H3K9, H3K36, and H4K8, resulting in decreased transcriptional activities of sterol regulatory element-binding protein 1c, ATP citrate lyase, and fatty acid synthase. These results suggest that TBS inhibits the NAFLD transcription-modulating activity of lipogenesis-related genes through modification of histone acetylation.

The hat is the most flexible human head covering. Almost entirely enveloping the hair, it can be simple, pure, elegant and mysterious. Yet it is frequently a highly decorative form of dress. The hat also takes a part in the extension of the area of art as soft-sculpture. My purpose of this thesis is to present diverse artistic hats with natural images by nontraditional materials and natural resources. The reason why I select nature as them is that it is absolutely the origin of life and art. To develop the innovative hat design, I focus on the material to extend the range of art expression. I observe nontraditional materials such as wire, paper and so on that enhance heterogenetic feeling from natural images. The attempt is made to enhance the visual effect by harmonizing the disharmonious feeling. Natural resources such as moss, orange, feather and so on could be adapted to the hat and applied for unique design, which supplies new expression. Therefore, the harmony of natural images and natural resources could avoid dullness, bestow elegance and polish the unique beauty creation of the hat.
