The knitting, which has developed from the onset of human civilization, has a close relation to dwelling as well as to clothing itself. Its progress has taken shape in a variety of forms according to nature-friendly tools and its knit texture in the past is different from that of modern times. With this basic idea, the work aims at the further study of various knitting structure which triggered the origin of modern techniques, the establishment of those methods, and the finding of what means was utilized earlier based on these. By doing that, this study will provide the foundation in the Korean historical timeframe in knitting field and give definition to knit wear in a historical sense. As to definition, the outcome in the research boils down to two categories. broad meaning and narrow meaning. The former can be the hook-formed textile, referring to making, twisting, or binding the knots. On the other hands, the latter, that is, narrow type, can be the loop-linked fabric which can be defined as modern knitting. The knitting dates back to the ancient way of binding structure, combining structure in other words, and braiding structure and this kept dividing into subgroups like Netting. Nalbinding, Sprang and Crochet as the usage of hands and tools by mankind has got improved. And it changed into knitting and crochet which means a bamboo needle-hook knitting (larger needle type) and a crochet-hook knitting (smaller needle type), respectively through middle ages and modern times and settled down to the production of fabric. In this work, Netting, Nalbinding, Sprang and Crochet are classified as ancient category in which these originate the modern knitting method. Though the modern type of knitting is not found in the Joseon Dynasty, some various methods from the ancient twisting skill and binding skill where the materials with easy access to acquisition in the nature such as rattan, straw, horsehair, hemp, rush, cotton, silk and the like to Netting, Nalbinding and Sprang except Crochet were handed down and used in costume for diverse application. This work can provide the basic frame in terms of Korean history of knitting which has been excluded in the relevant researches until now. When applying the study, it would trigger the initiation of more versatile design with which the previous unique techniques along with modern techniques can be adopted in the clothing market as knit designs gain in public favor more and more.

The idea of King Hungdok's prohibition of clothing was to restrict the use of chinese-made cloth on the one hand and to compell his people to use Korean-made cloth for their apparel on the other. The prohibition of clothing sprang from King Hungdok's aspiration to restore his dynasty that had been falling due to the repeated drought disaster and luxurious living of the aristocracy. Safflower, Rubeaceae roots and Sapan wood are well known as some of the earliest natural red-dyes, exhibiting beautiful red-color in our anciet cultural tradition. The color yellow was considered from ancient time to the Chosun Dynasty as the central color. Thus, this color became the royal color for the costumes in the palace. Those plants used to make the color yellow are: Gardenia, phellodendron amurense, Turmeric, coptis, safflower, Arthraxon hispidus, Styphnolobium japonicum. Shikon, root of violet plant, is well known as one of the earliest natural days. By repeating the difficult process of making various dyes constantly during many centuries, the Korean people developed the marvelous technique of making natural color.

Various changes in ocular position are possible during general anesthesia as opposed to the awakening state. However, unexpected ocular deviation under general anesthesia is a disconcerting event as it can lead to difficult complications intraoperatively. To date, sudden fixed upward ocular deviation has been rarely reported previously. This phenomenon was observed in an 8-year-old boy during strabismus surgery. Suddenly fixed upward ocular deviation occurred when the speculum was inserted into the right eye. When the eyeball was pulled down, using forceps, there was some resistance, such as contracture of superior rectus. The eyeball sprang back into the upward position when the forceps was released. These changes could hamper the good exposition of the surgical field, leading to significant intraoperative difficulties and complications. Surgeons should be aware of this possibility, despite general anesthesia; if it occurs, proceed with the surgery as planned preoperatively, and both ophthalmic and anesthetic interventions should be used to solve this problem.

We live in a global village that requires a language with a genuinely global status as a means of communication. During the twentieth century, English has clearly emerged as the lingua franca owing to both past British political imperialism and the more recent superpower status of the United States. Further contributing to world domination of the English language is the fact that the computer and Internet sprang from the US. Whether you like it or not, you are destined to learn English at least to some extent in order to live in this global village. For the last two decades, one of the most mistaken ideas a number of Korean English teachers have had is that speaking and listening are the primary forms of language, while reading and writing are secondary. In fact, reading is regarded as a skill of much consequence to us since it provides us with access to a huge quantity of information on the Internet, of which at least 80% is written in English. Writing, too, deserves a great deal of attention because we are increasingly called upon to use standard English expressions. As diligent learners of English, we had better not forget the place accorded to language not only as a medium for exchange and constructing information but as a tool for thinking. So we should try to think in English to the point where we have thinking-in-English as a habit, thereby leading to increased familiarity with the language. Such familiarity entails, above all, possessing a command of English.

In this paper, a Magnetic Core Reactor (MCR) which forms a part of the DC reactor type three-phase high-Tc superconducting fault current limiter (SFCL) has been developed. This SFCL is more economical than other types with three coils since it uses only one high-Tc superconducting (HTS) coil. When DC reactor type three-phase high-Tc SFCL is developed using just one coil, fewer power electronic devices and shorter HTS wire are needed. The SFCL proposed in this paper needs a power-linking device to connect the SFCL to the power system. The design concept for this device was sprang from the fact that the magnetic energy could be changed into the electrical energy and vice versa. Ferromagnetic material is used as a path of magnetic flux. When high-Tc superconducting DC reactor is separated from the power system by using SCRs, this device also limits fault current until the circuit breaker is opened. The device mentioned above was named Magnetic Core Reactor (MCR). MCR was designed to minimize the voltage drop and total losses. Majority of the design parameters was tuned through experiments with the design prototype. In the experiment, the current density of winding conductor was found to be $1.3\;A/mm^2$, voltage drop across MCR was 20 V and total losses on normal state was 1.3 kW.

This study, on the American hippies and their fashion, is composed of an examination of the following; the social and cultural circumstances of America in the late 1960's, the charac? teristics of the hippies that appeared in the midst of the foresaid background, how those factors materialized in the hippies' distinctive fashion and how they influenced tahion to come. The hippies were composed of the young generation that revolted against all general conventional values of American society and seceded from it, seeking for the ideas of love and freedom. They expressed their newly defined culture-rock music based on drug culture, psychedelic art, rejection of an established society and ethnic tastes that sprang up from nostalgia concerning nature-by means of their own distinctive fashion. And as a revival of the hippies' fashion, neo-hippie and grunge fashions newly appeared in the F /W season of 1992 and afterwards, adding fresher and more abundant sensibility to the original image and layered look of the hippies. The hippies' fashion has not only played a significant part in modem fashion history but will continue to exert its influence in the 1990's as the hippies generation are presently the center of American culture and leaders of world culture. In conclusion, various sorts of "individ- uality" and "the pleasure in the wearing itself" expressed by the original layering of the hippies' fashion presents new promise in the coming development at fashion.

The purpose of this study is to present a classification system of the hand-made and machine-made lace according to the configuration method and re-make the category and definition of lace to consider the emergence and development of major laces techniques. The re-made category and definition of the lace is as follows. The lace usually consists of ground and motifs, however, the techniques of netting and sprang are suitable for making ground than motif, so I think it is appropriate to exclude them from the category of the lace. Many scholars are excluded openwork embroidery fabric from the category of the lace. But, an openwork embroidery fabric is the basis of a needle point lace called true lace and is consist of motif and ground. I think it is appropriate to include it in the category of the lace. I think it is also appropriate to include in the category of the lace that the eyelet embroidery fabric which mimics the openwork embroidery fabric in the machine. Lace is redefined that a fabric with openwork decoration consists of motif and ground, constructed by a variety of ways such as plaiting, twisting, looping, knotting of threads or embroidering by hand or machine. The classification of the lace is presented as follows. Hand-made lace is classified bobbin lace, needle point lace, embroidery lace, knotted lace, crochet lace, and knitting lace. Machine-made lace is classified raschel lace, leaver lace, torchon lace, and machine-made embroidery laces which include tool lace, eyelet embroidery lace, chemical lace, etc.

To study effects of methanol extract of prosomillet on lopid metabolism , five groups of male Sprang-Dawley rats weighing 116$\pm$9 g were fed test diets for four weeks. The five diets consisted of one low fat(5% w/w) diet containing starch as carbohydrate source(normal) and four high fat diets(15% w/w) containing 40.5%(w/w)sucrose(control) and additional 80% nethanol extractof prosomillet at the levels of 0.3% and 1%(w/w) or prosomillet powder at the level of 20%(w/w). Serum level of total cholesterol was a little higher but that of triglyceride was 41% lower in 20% (w/w) prosomillet powder group than in the control group. The cholesterol levels of two Liver cholesterol levels were lower and phospolipid levels higher in all three prosomillet powder group . Fecal excretionof bile acid was most increased in the prosomillet powder group among all five test groups. Acitivity of liver microsomal 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase was significantly lower in 0.3% methanol extract fed group than the control and also appeared to be reduced in 1% extract fed one, wherease those of 20 cholesterol 7$\alpha$-hydroxylase were not different among the five groups. Activities of liver cytosilic glucose-6-phosphate dehydrogenase(G6PDH) and malic enzyme were decreased in 0.3% prosomillet methanol extract and 20% powder groups. The results indicate that in addition to fiber, certain active components in prosomillet have potential to exert hypolipidemic effects via regulating hepatic cholesterogenesis and lipogenesis.
