Hats are an important part of the fashion accessory business and Their importance is increasing year by year. Their importance is increasing not only as a means of accessory ut also as a means of sportswear due to the leisure-sports boom of the 90's. As hats are becoming more and more popular and ready-made, demand for comfortable and easy-fitting hats are increasing. Being an piece of apparel, fitting is very important factor in hats as well s in other forms of clothing. But many hat-wears complain of dissatisfaction of fitting of their hats. In addition to this, another problem is hat most hat designs have been flown in from the West without inspection of their fits. Designs to fit the Koran face and head have not been developed properly. This study is based on the need for the development of a well-fitting hat pattern design for Korean young women. After taking actual measurements of 170 young womens, a size system was organized for developing patterns for different size groups.

해상풍력 발전시설은 국제적인 설계기준조위로 최고천문조위(highest astronomical tide, HAT)와 최저천문조위(lowest astronomical tide, LAT) 기준을 요구하고 있다. 우리나라는 설계기준조위로 약최고고조위(AHHW)와 약최저저조위(ALLW) 기준을 사용하여 왔기 때문에 국제적인 설계기준을 만족하기 위해서는 해상풍력 발전시설 후보 해역인 위도에서의 HAT, LAT 추정이 필요하다. 본 연구에서는 위도에서 가용한 31년 조위자료를 이용하여 HAT, LAT 기준조위를 추정하였으며, 추정에 사용한 자료의 신뢰수준을 검토하기 위하여 장기 태음분조에 해당하는 18.61년 주기의 Nodal 변동 특성 분석을 수행하였다. Nodal 보정을 고려하지 않은 연간 $M_2$, $O_1$, $K_1$ 분조의 진폭변화는 뚜렷한 18.61년 주기를 보여 조화분석 결과가 적절하게 추정된 것으로 파악되고 있는 것으로 파악되었다. 한편 조위자료를 이용하여 추정한 HAT, LAT 신뢰구간의 상한 및 하한으로 최종 추정한 HAT, LAT 조위는 AHHW, ALLW 기준조위에 비하여 각각 +40 cm, -35 cm 정도로 파악되었다.

For the design of wind-power facilities, the highest and lowest astronomical tides (HAT and LAT, respectively) are needed for the tidal-water levels regarding international designs; however, the approximate highest high water and approximate lowest low water AHHW and ALLW, respectively, have been used in Korea. The HAT and LAT in the wind-farm test-bed sea should be estimated to satisfy the international standard. In this study, the HAT and LAT are therefore estimated using the hourly tidal-elevation data of the Eocheongdo, Anmado, Younggwang, Gunsan, Janghang, and Seocheon tidal-gauging stations that are located in the adjacent coastal sea. The nodal variation patterns of the major lunar components, such as $M_2$, $O_1$, and $K_1$ are analyzed to check the expected long-term lunar cycle, i.e., 18.61 year's nodal-variation patterns. The temporal amplitude variations of the $M_2$, $O_1$, and $K_1$ clearly show the 18.61-years periodic patterns in the case of the no-nodal correction condition. In addition, the suggested HAT and LAT elevations, estimated as the upper and lower confidence limits of the yearly HAT and LAT elevations, are 50 cm greater than the AHHW and 40 cm lower than the ALLW, respectively.

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 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.

The purpose of this study is to investigate the historical background and basic composition of costume of the Baekje period. Main official hats of Baekje include the transformed hat, jougwan and daeryun-style ipsikgwan. Daeryun-style ipsikgwan employed chowha shape in most cases, symbolizing good auspice under the harmony of the male and female principles. Main types of costume of the Baekje period are po, yu, go and sang. The king, governmental officials and the common people all put on po of jikryeong gyoim style. Yu' is classified into two styles, chaksu with the narrow sleeve and daesu with the broad one. 'Go' has two styles, gunggo and gwango. The former is narrow in the breadth of the trouser and the latter, wide. 'Sang' is classified into various style according to whether it contains stripes of many colors, thin wrinkles or thick wrinkles. For the decoration of official hat used in the period of the Three Kingdoms, Baekje employed chowha in shape, Kokuryo, chowha and joik and Shilla, joik. In Baekje, rhythmic patterns of flame were applied to official hats, presenting brilliance. In Shilla, shaking geumyeongrak was used for official hats to show movement. In Kokuryo, such hats used flapping feathers, symbolizing dynamic power. Most necklaces and bracelets of the Baekje period were simple and plain.

This paper presents a theoretical approach for a modified turnstile antenna suitable for satellite communication in order to investigate the current distributions of radiators and radiation characteristics with equivalent model analysis. The proposed equivalent model is composed of an ideally horizontal dipole antenna and vertically loaded top-hat radiating elements. The required isoflux pattern with wide beamwidth has been achieved by attaching top-hat elements to the main radiators. In addition to illustrating radiation patterns, electrical performances like current distributions have been analyzed by mathematically manipulating the equations derived from the equivalent horizontal and vertical dipole model.

This study is about'The Costumes of Ch'oyong dance. (namely Ch'oyong-mu-bok; 처용무복)': emphasis on its structure and change. 1 studied Akhakguebum (the book of music and dance; 낙학궤범), Eui-Gue-Do (a collection of a series of paintings showing the whole processes of the royal courtesies and ceremonies; 의궤도) and some genre painting (풍증화). 'The costumes of Ch'oyong-Dance'were composed of robe(의), pants-skirt(대) , outer-skirt (상) , scarf-string(천의·길경) , shirt(한삼) , hat with mask (사교·가면) , belt(대) and shoes (혜) . According to the position, the colours of robe(의) and pants-skirt(군) were different. What is called, it is'the Colour of Five-Position (오방색) .'The Costumes of choyong-Dance' can be divided three factors by its symbolic means; i. e. shamanism, buddhism and bureaucratism. The pants-skirt(군), outer-skirts(상), scarf · string(천의·길경) and mask are considered as shamanic factor. However, the scarf(천의) , string(길경) and patterns(만화)which are decorated with many lotus patterns enclosed with vine are considered as buddhistic factor. And the hat (사모) , robe(의) , outer-skirt(상) , belt(대) and shoes(잔) are considered as bureaucratic factor. Ch'oyong is endowed with some power by these factors, and its symbolic means became stronger and enlarged by 'the Colour of five-position'. As time goes, the forms and details of robe had been changed noticeable; sleeve-width, neck-line and patterns. The shamanic, buddhistic and bureaucratic factors are reduced. These changes were derived from the changes of Ch'oyong·Dance. On the ground of the shape of mask and round-neckline robe(단영) , someone has an opinion that Ch'oyong is an aribian. However, according to this study, Ch'oyonh is Korean traditional thing; round-neckline robe already existed and settled in Silla dynasty and Ch'oyong-mask symbolized shamanic power.
