Modernization of Korea had begun with the reformation of the Kab-o Reform in 1894, which the government had designed after the protectorate treaty with Japan in 1876. It had affected drastic changes on the formation and framework of a Han-bok by government and the main changes is found in creating new style of Gae-ryang Han-bok. During 1980's, the peoples were interested in traditional cultural heritage, and 'the campaign of wearing Woo-Ri Ot' prevailed in Korea to instill the radical sprit of Korean. A Han-bok, which was made at this time, has called a Saeng-hwal Han-bok. The purposes of this study are to defue the the words that are Han-bok, Gae-ryang Han-bok and Saeng-hwal Han-bok of meaning and characteristic based on the previous studies and historical materials and present a unified and historical opinion about Han-bok to the academic world and industry of Han-bok by the consideration. Han-bok is a traditional costume with a long skirt and long breast-tie based on the later Cho-sun and is emphasized a virtue and manner on it. Gae-ryang Han-bok is an improved Han-bok that is include with a Tong-Chima and Jeogori for making a movement and function better. Saeng-hwal Han-bok is originated by the movement of wearing Woo-ri Ot in 1984, is interpreted the traditional Korean beauty from the modem view and is a practice Han-bok for popularizing intodaily life. After investigating the 33 of previous studies, the characteristics and transitions of Han-bok are followed. First, the reason of fail about the reform of dress is a loss of traditional beauty. Second, the yes or no of the establishment of law about the reform of dress, it influenced on a reforming or wearing speed of costume. Third, after 8.15, a modem girl and girl student can not impact on a system of Korean women anymore because, the number of the group that means a high educated and active woman, was growing. So, the elevation of women's education matured the system of Korean women's costume. forth, western style clothes are popularized after the Korean War and it is set down in the system of Korean women's dress.

We can study and judge the costumes of the Three Kingdom period through an ancient tomb murals and various burial mound(clay) figures, however, it is quite difficult to search for costumes of the Goryeo period ($960{\sim}1392$), because dresses from this era were rarely found, related antiquities are limited and hard to survive. This is the reason why people say that the Goryeo Dynasty is the period of undiscovered era for its history of costumes in Korea. Fortunately, these days, there are various kinds of buddhist statues discovered with its burial accessories such as costumes and dyed fabrics of the Goryeo era. Through these, we can glimpse through the Goryeo cloths and develop our researches on this field. In addition, a man called Seo Geung(서긍, the Chinese scholar Xu Jing) wrote a book in the 12th century about peoples lives in Goryeo and in this book, there are few documents about the people's costumes which help us to understand the period's traditional dresses. In this paper, we will look for the traditional costumes which were formed and developed through people's lives in Goryeo, using remains from various burial accessories in buddhist statues as well as the documents related to the costumes written in ${\ll}$Goryeosa 고려사${\gg}$. Moreover, costumes of a period usually developed and influenced by the atmosphere of people's lives both economically and mentally, therefore, in this study, we will especially focus on the dresses of the bureaucratic officials and their wives, who led comfortable lives and latitude of mind. Through the records, like Silla, Goryeo exported Sehjeo(세저) and Sehjoongmapo(세중마포) to China. And we found out that Silla's skillful weaving techniques of hemp and ramie cloths were succeeded to Goryeo. According to above facts, Goryeo people made clothes with various kinds of fabrics such as, different sorts of silks, ramie, hemp cloths and cottons. They also have very skillful manufacturing techniques for certain textiles. Their official robes were generally influenced by Tang and Song Dynasty, but, like ordinary people, we found out that the government officials also wore baji(pants) and a jeogor(jacket), which were traditional costumes since the Unified Silla Kingdom with various coats. Especially, women's costumes such as jeoksam(unlined summer jacket) and hansam(한삼), which are sort of jeogori(jacket), baji(pants) and chima(skirts) were made of various kinds of silks and ramie cloths, that were generated from the Goguryeo Kingdom, with jikryeongpo(a long jacket and striped skirt).

We propose a frequency selective surface(FSS) using double split ring resonators(DSRRs) for isolation enhancement between CDMA and RFID. The structure consists of an outer SRR and an inner SRR, and the gaps are formed in the same direction. By properly adjusting the gap and line width, the resonant frequency and skirt characteristics can be adjusted without varying the unit cell size. The proposed structure has a different field distribution from that of an ordinary SRR for magneto-dielectric materials. One layer consists of $9{\times}9$ unit cells and the other layer was separated by 50 mm. To validate the simulation results, we fabricated the patch antenna and the FSSs, and the measured results show a good agreement with the simulated ones. The electrical size of the unit cell is $0.110\;{\lambda}{\times}0.110\;{\lambda}{\times}0.002\;{\lambda}$, and the size of the two layer FSS is $1.058\;{\lambda}{\times}1.058\;{\lambda}{\times}0.153\;{\lambda}$. The two layer FSS maintain gain in CDMA frequency and has 6.9 dB reduced gain in RFID frequency.

When we design a dress, we should not only consider the esthetic sense and the relationship between movements of the body and the type of dress, but also the combination between the qualities and proper uses of textiles. recently the sale of ready-made clothes has been booming but I wonder whether they have been made in accordance with research concerning body movements and dresses. I would like to make the following observations on dresses, because I have personally suffered the inconvenience of restricted arm movements when wearing ready-made clothes. I have made four types types of foundations with muslin and Jersey, with these foundations I measured the degree of tension or how much the waist-line was drawn up then the arm was moved in increments of 45 degree angles and there by covering the entire span of vertical and horizontal movements. I have intended to experiment with sleeves of differing height in several ways. Concerning the movement factor, I have determined that with excessive activity vertical movements are twice as uncomfortable as horizontal movements. Concerning the faburic, I have found that because jersey has more elastic qualities than muslin, it has proven to be more responsive to body movements. concerning dresses, I have fund that the higher the height of the sleeves, the more uncomfortable it is to move the arms and the greater the degree to which the waist-line is drawn up. As a result this experiment I have made the following observations. Firstly, the vertical movement of the arms to a 180 degree angle has the most extreme influence on the breadth of movement of the waist-line. Secondly, because jersey permits freer body movements than muslin, it should be the preferred material for use in making sportswear. Thirdly, the formula A·H/4+3 of the sleev's cap height is suitable for making street dresses and formal wear. The formula A·H/5 and A·H/6 are properly used when making working clothes and sportswear, and the formula A·H/8 is proper for a sleeping garment and clothes for patients. Fourthly when deciding to any garments, it is important to consider the amount of arm movement anticipated and the relationship between the material and the degree to which the waistline is drawn up. In nder-blouse, when we raise our arms to the most extreme position, we should at that point still have 20∼25 cm of material remaining under the waist-line which includes the maximum of 14.1cm plus part of the blouse and breath of skirt's belt. In the case of the over blouse it is proper for us to have the length of 17∼20 cm remaining below the waist-line.

Since unloaded Q-value of a high-temperature superconductor(HTS) filter is very high, a bandpass filter(BPF) and a lowpass filter(LPF) with an increase of pole numbers can be fabricated without an increase of an insertion loss(IL) ; recently a 70-pole BPF is developed in USA. They have an abrupt skirt property and an excellent attenuation level for out-of band. Moreover, they can be miniaturized when lumped element resonators or the slow-wave characteristic are used. Technology of fabricating a HTS epitaxial film as well as a film of a 4 inch area also makes the planar type filter with a various structure and an enhanced power handling capability possible. Recently, the HTS filter subsystems composed of a planar-type HTS filters, a GaAs-based LNA and a mini-cryocooler are developed. The extended receiver front- end subsystems for mobile radio communications decrease the noise-figure level of the communication system and the frequency interference interacted adjacent bands, and increase the efficiency of frequency and the capacity of communication system. In this paper, theory for developing the HTS filter, its kinds, its design rules, its characteristics are reviewed. The feature of the research and market trends related to the HTS filter systems for the receiver front-end subsystem of mobile base station are surveyed.

Kon-myuh was worn by the ancient Chinese and Korean rulers as ceremonial dress during special rituals such as worshipping heaven and ancestors marriage or funerals. kon-myun consists of two major parts-Myun and kon-bok (the main bodypiece) as well as other articles of clothing(skirt footgear etc), There were regulations set in ancient books describing in detail the make of the kon-myun number of ryu and symbol to be used all which applied to each ruler depending on rank and status. This study is aimed at examining the consistency of the korean and Chinese in following the regula-tions as seen in relics which have been recovered from the past. Based on historical findings it seems that Korean Kon-myun came to Korea from China during the Three Kingdoms period. It was also worn in the Koryo and Chosun Dynas-ties and the Taehan Empire. In studying Konmyun in Korea the researcher studied a book from the early Chosun dynasty, Kukjo-oryeuiseory and a book from the late Chosun Dynasty Kukjo-sangrye-bopyun to find the guidelines and rules applying to the Kon-myun tradition. Slight difference were found across time in the supplementary articles of clothing as seen in Uigwe Pokwan-doseols explanations and drawings of Kon-myun. The researcher used uigwes of funerals of kings of the Chosun Dynasty and observed change over this period of time. However there was a clear consist-ency: the king's Kon-myun consisted of 9ryu-myun 9chang-bok while that of the prince consisted of 8ryu-myun 7chang-bok. For the Taechan Empire the researcher used Tae-han Yae-jun which shows the emperor's kon-myun to have consisted of 12ryu-myun 12chang-bok. To study how the regulations were put into practice relics were uncovered from the periods being studied. A portrait of King Ik-Jong remnants from King Ko-jong's Kon-bok and a photograph of Emperor Sun-jong all were in close adherence to the regulations outlined in the books. In China Kon-myun was worn by emperors from the Han to the Ching Dynastices. The researcher investigated Kon-myun es-pecially in the Ming Dynasty. The Kon-myun regulations as read in Tai-ming-hui-chan changed through all four periods. To study the faithfulness of practice to low Ding-ling the tomb of Emperor Shin-jong who ruled during a period of the Ming Dynasty was unearthed and the remains of the Emperor's Kon-myun were analyzed. The Kon-myun consisted of 12ryu-myuh 18chang-bok and there were other differences I color symbols and wearing method when compared to the regulations. It can be concluded that the Chinese Kon-myun tradition was not in strict adher-ence to the regulations established by law books. This is in contrast to the Korean Kon-myun tradition which showed little devi-ation. Further study is needed to understand why there was this difference in tradition and ritual.

Focusing on khotan located in the southern Silk Route which was one of the most important kingdoms in the Tarim Basin this study attempts to examine the changes of costume in Khotan by compar-ing the costumes in the painted panel showing the story of silk princess with the excavated costumes from ancient tombs. Furthermore this study attempts to inves-tigate the impacts of cultural exchange be-tween China and its western neighboring country Eastern and Western Turkestan on costume. Excavated costumes from the Shanpula ancient tomb in the region of Khotan and from ancient Niya in the esat-ern border of Khotan and discoveries from Rawak and Dandan-oilik near by Yotkan the ancient capital of Khotan are exam-ined. Basic Khotan's costume was the two piece style of tops and trousers. Over the basic costume wearing a top wear with half sleeves was popular. Skirt was worn by women. Even though there were many kinds tops were classified into the two types kaftan and tunic. Thouth Khotan maintained a association with China for a long time the style of Khotan costume had imbued to China. Top wear with half sleeves was worn frequently in Khotan. Also in China top wear with half sleeves was worn as over-wear which was called ban-xiu ban-bi bei-zi Costume style of China is covering the body profoundly and wrapping front edge toward the right. The types of chi-nese top wear with half sleeves for exam-ple round-neck·confronting front edge crossing-neck·confronting front edge tu-nic type discord with the traditional chi-nese costume style There were many cas-es that half sleeved top wear was worn as over wear in T'ang dynasty. The phenom-enon was due to the prevalence of 'ho' (foreign) and half sleeved top wear was introduced by the countries to the west of China Khotan. A round neck garment was a general type for the men of cuntries to the westof China. Also Chinese wore round neck garment since South and North Dynasty The type of Chinese round neck garment was not tunic but kaftan. From costume relics and ancient paintings the type of Khotan's round neck garment was tunic which was recorded on the Chinese histori-cal documents as " guan-tou-shan" that is tunic the type of persian costume, Even thgough the painted panel showing the sto-ry of silk princess was made in the it me when Turks was a dominion on Central Asia Khotan's costume style was not changed toward Turk's costume style and remained tunic style.

The purpose of this research is to conserve of golden decoration(Jikgeumdan) of Chima(skirt) and Jeogori(Korean jacket) of the costumes excavated from Hangju Gi' tomb(17th Century) of Joseon dynasty$(1392{\sim}1910)$ and to focus on the development of conservation skill to prevent flakings of gold leaves in gilt paper strips. Up to the present, in case of golden decorations of costumes excavated from tombs of Joseon dynasty, some of gold leaves in gilt paper strips of costumes were flaked away by deterioration of adhesives in tombs. However, most of gold leaves were flaked away and totally lost by wet cleaning for eliminating contaminants after excavation. In order to prevent flaking, preliminary experiments for re-adhesion of gold leaves have been carried out. Firstly, simulation was performed using gold leaf which was available in the market. Adhesives used in this research were water-soluble adhesives(hide glue(cow, rabbit), glue made from air bladders of sciaenoid fish and Primal AC-3444 of acrylic emulsion) and solvent-soluble adhesives(acrylic adhesive Paraloid B-67 and B-72). Because of difficulty in wetting and spreading of adhesive solutions into the interface between gold leaf and Korean paper, water-soluble adhesives were not proper for adhesion of gold leaf and Korean paper. Solvent-soluble adhesives were easily infiltrated into interface between gold leaf and Korean paper and the adhesive force was also satisfied. From this result, the researchers chose more flexible Paraloid B-72$(Tg\;40^{\circ}C)$ 1% solution than Paraloid B-67$(Tg\;50^{\circ}C)$ for adhesion of gold leaf and Korean paper. Secondly, using Paraloid B-72 1% solution, the estimations of re-adhesions of gold leaves in gilt paper strips of Jeogori were carried out. When Paraloid B-72 1% solution was injected three times into the interface between gold leaf and Korean paper, the re-adhesion was most effective. On the basis of the results in these preliminary experiments, re-adhesions of gold leaves in gilt paper strips of Chima and Jeogori were carried out on condition of three times injections of Paraloid B-72 1% solution before wet cleaning. After wet cleaning, the most of the gold leaves were survived, which was confirmed by both the examination with the naked eye and the microscopic examination.

Effect of the microbial product made of Bacillus stearothermophilus DL-3, which was isolated from the soil and identified in this study, and rice bran on microorganisms in soil and growth of lettuce (Red skirt lettuce) and Chinese cabbage (Ga rack new No.1 Chinese cabbage) was investigated. Total numbers of microorganisms in the pot with untreated soil, treated with standard amount of microbial product and treated with double amounts of microbial product for growth of lettuce after 6 weeks were 2.78${\times}$10$^{7}$ CFU/g, 2.72${\times}$10$^{8}$ CFU/g and 3.63${\times}$10$^{8}$ CFU/g. Total numbers of microorganisms in the soil without treatment of microbial product and treated with standard amount of microbial product were 2.06${\times}$10$^{8}$ CFU/g and 5.49${\times}$10$^{8}$ CFU/g. Total numbers of microorganisms in the pot with untreated soil, treated with standard amount of microbial product and treated with double amounts of microbial product for growth of Chinse cabbage after 6 weeks were 1.43${\times}$10$^{7}$ CFU/g, 3.42${\times}$10$^{8}$ CFU/g and 7.22${\times}$10$^{8}$ CFU/g. Total numbers of microorganisms in the soil without treatment of microbial product and treated with standard amount of microbial product were 5.75${\times}$10$^{8}$ CFU/g and 7.96${\times}$10$^{8}$ CFU/g. On basis of leaf length, leaf width, leaf number, wet weight and dry weight, the growth of lettuce and Chinese cabbage on the soil treated with microbial product was faster than that on the untreated soil. The treatment of microbial product in the soil resulted in the increase of useful microorganisms, which seemed to enhance the growth of lettuce and Chinese cabbage.

This study was conducted in order to find out the tendency of sericultural woman's clothes. This data was based on random samples of 183 sericultural women throughout the country, and was derived from the investigation of c1othes (western and Korean-style) which had been made during the years, 1967∼1969. The results obtained are summarized as follows: 1. Western-style clothes were about twice as popular as Korean-style, and more evident among the young women. It was also shown that the ratioes mentioned above were gradually decreased year by year. 2. Most popular among the western-style clothes were blouses, one-piece dresses and skirts. Jogori(coat) and Cheema(long skirt) were favorites among the Korean-styled clothes. One-piece dresses showed increasing tendency of use year by year. 3. Costume-made clothes were much more in number than the home-made and the ready-made types. The home-made and the ready-made clothes increased as the ages increased. 4. Western-styled clothes were popular in summer seasons while Korean-styled clothes were popular in the winter time. Among the western-styled clothes one-pieces dresses and two-piece suits were most popular during the spring through autumn. In Korean clothes the Cheema was popular all year round. 5. Western-style clothes were mostly made of polyester and their blends. Silk was the least used fabric. On the contrary, most of Korean-style clothes were made of silk and their blends. The synthetic fibers showed increasing use year by year. 6. Favorite colors were in order; white, blue, brown, and black in western-style clothes; white, blue, green, and gray were in Korean style clothes. Young women teaded to have a wider preference of colors than the older women.
