  • In this paper, we designed 32-Hit MAC architecture of a RISC Processor for portable terminals such as cellular telephones, personal digital assistants, notebooks, etc. In order to have minimum area with best performance, the MAC performs 32 by 8 multiplication per cycle, with early termination circuit that enables multiply cycles depend on the value of multiplier. It uses the sign bit of a partial product and two extra bits for sign extension, The MAC is modeled and simulated in RTL using VHDL. The MAC is synthesized using IDEC C-631 Cell library based on 0.6$\mu\textrm{m}$ CMOS 1-Poly 3-metal CMOS technology.

  • The analysis category of Art to Wear was text analyzed from the research material of 100 projects put together by fashion specialist. The conclusion of Art to Wear was comprehended the general features of it were compared and analyzed from a semiotics context. According to this analysis, the formative features of modern Art to Wear is categorized into three different dimensions from a semiotics light. The formative features of modem Art to Wear in the light of syntactic dimension was divided as an open constructed shape of Space Extension, non-typical Deformation, Geometrical Plasticity. The formative features of modem Art to Wear in the light of semantic dimension express symbolic meaning through metaphorical sign. These sign reflect the body image of the life and death and its objective of Abjection, Hybrid of discultural appearance and the image of Hyper-reality, which are features used to comprehend the inner meaning. The formative features of modem Art to Wear in the light of pragmatic dimension divided the artist emotion and meaning system delivered by Emotive Image, the Phatic Image that arouse inner signification and the Poetic Image which contain artistic and aesthetic meaning within it.

  • Body has been high-lightened as one of the most important theme since the philosophy and the arts are focused on it in the late 20th century. It would be of worth to study the characteristics of contemporary fiber-art works, especially done by Abakanowiz who has been regarded as a dominant pioneer in the contemporary fiber-arts from the viewpoint of inter-grade of the physicals and the mental. This paper, therefore, deals with the Abaknowiz' works in the context of human body and body-signs. Life and works might be classified into 5 stages: first, learning period since her birth in 1930, second, creation period of Abakans, third, remodelling period of Abakans, fourth, composition and dissolution period of Abakans and the last and fifth, new transformation period of Abakans. 'Abakans' through her whole life as an artist have been a plastic language and based ultimately on external human body but in various materials and forms. Abakan as a human-sign uses the past experiences and the texts of the other world in mixed and overlapped forms. Life-size Abakans by Abaknowiz can be easily understood as Abakanowiz herself and her Polish ancestor at the same time. The neuter Abakans with mashed face and obscure body is a expressive figure of coexisting world with opposite concepts like war and ideology, anxiety and freedom, man and woman, and etc. Human body as body-sign is an extensive image has existed since our forefathers and overlapped with the inter textual and the popular images. 'Abakans' that is our world and inner-self at the same time might be a window through which she tries to show what the world is.

  • DMT 방식의 송·수신기는 파일롯 채널의 페이즈 정보를 이용하여 샘플동기를 맞추게 된다. 파일롯 채널의 페이즈 값은 심볼 단위로 행해지는 FFT 결과에서 구할 수 있으므로, 심볼동기를 샘플동기 이전에 맞추어 주어야 한다. DMT VDSL시스템의 경우, 심볼 내의 반복되는 구간사이의 상관성을 통해서 심볼동기를 구할 수 있게 된다. 수신신호의 부호를 기본으로한 최우도 추정함수를 사용하여 심볼동기를 구하는 기법에 대해 제안하였으며, Tx 윈도우에 의해, 심볼동기의 추정값이 잡음에 민감해지는 것을 막기위해 가중합을 적용한 추정 방법을 제안하였다. 송·수신기 사이에 샘플링 클럭 옵셋이 존재할 경우, 샘플동기를 위해 디지털 영역에서 샘플링 클럭 옵셋을 보정해주는 기법을 제안하였다.

  • The purpose of this study was to evaluate an effect of change on head posture initial occlusal contacts with measuring the distances between initial occlusal contacts and maximum intercuspal position at different head posture in TMDs patient. For this study, 24 patients from age 13 to 36 were selected, they were examined health history taken, patients who have sign and symptoms of TMDs were examine before the study. For the normal group, 21 adults from age 23 to 25 were selected. They have normal or class I molar relationship, and have no other prosthetic restorations. Difference on distance between initial occlusal contact and maximum intercuspal position with mandibular kinesiograph$(MKG^R)$(K6 diagnostic system, Myo-tronic Inc, USA) in upright, supine, 45$^{\circ}$ extension, 30$^{\circ}$ flexion position of the head were measured. The Frankfort horizontal plane was used as a reference plane. The results were as follows : 1. There were significant differences between initial occlusal contacts of the normal and patient group on upright position and 30$^{\circ}$ flexion of the head(p<0.05, p<0.01) 2. The position of the initial occlusal contacts have a tendency to place anterior and inferior to maximal intercuspal position in upright position and 30( flexion of the head as well as posterior and inferior in supine position and 45$^{\circ}$ extension of the head in the normal and patient groups. 3. There were significant differences among the initial occlusal contacts between uptight and supine position; upright and 45$^{\circ}$ extension of the head(p<0.05); supine position and 30$^{\circ}$ flexion of the head, .and 30(flexion and 45$^{\circ}$ extension of the head in the patient group(p<0.01) The result have shown that after treatment on the supine position, it may be necessary to check occlusal contact on the upright position as well ass flexion of the head. It may need careful adjustment in occlusal condition on upright position of TMDs patient.

  • T-shirt has changed into advanced and stylish outwear by new paradigm, taste of consumer, awareness of recycling, spread of subculture, DIY culture, refusal of standardization and pursuit of high quality goods, etc. The purpose of this study was to analyze aesthetic characteristics of t-shirt designs that changed into diverse designs in world fashion college since 2000. The method of this study was to analyze documentaries, fashion magazines and internet fashion site. Aesthetic characteristics of t-shirt designs were expressed in deconstruction, mixture, integration and imitation. And each of external expressions and internal meanings was as follows: First, deconstruction was expressed in partial cutwork and three dimensional texture by sewing and construction drape. It means breaking the conventional structure and break-ing the boundary of t-shirt and another item and possibility of multi-vocal analysis. Second, mixture was expressed in collage of diverse ornaments, diverse fabrics and diverse patterns. It means exceeding the limit of material, elaboratenes and high quality of handwork, reflection of self-identity, brand image, fashion trend, consumer's psychology and mind of experimentation and couture. Third, integration was expressed in extension of length, width, use and style. It means unification of functions, deconstruction of items and extension of meanings and images. Forth, imitation was expressed in stain of dye, irregular and ripped sign, cut out, rough warp, drawing and washing, etc. It means subculture, rarity value, monopolization, diversity, familiarity, yearning and uniqueness.

  • Neurinoma originates from any nerve covered with a Schwann cell sheath and can occur in any cranial, sympathetic, or peripheral nerve. Hypoglossal neurinomas are rare and most of them are intracranial, but they may extend extracranially. Most intracranial neurinoma arise from the sensory division of cranial nerve but a motor nerve such as hypoglossal nerve is rarely involved. Although the typical sign of hypoglossal neurinoma is ipsilateral hemiatrophy of the tongue, it is easily overlooked. For the diagnosis of hypoglossal nerve tumor, CT scanning with contrast enhancement and MRI should be included, and they are greatly aids in planning the radical removal of the tumor. We experienced a case of intracranial hypoglossal neurinoma with extracranial extension in a 43-year-old woman. The patient showed otherwise unremarkable except 4 months history of right infraauricular mass and right tongue hemiatrophy. Computed tomography and magnetic resonance imaging for local diagnosis was valuable and we could remove the mass by one stage operation via suboccipital transcervical approach.

  • The purpose of this study is to survey job stress and Musculoskeletal Disorder(MSDs) of workers in small plants with agricultural products. The subjects were comprised of 69 workers participated in "Helping the rural women to get the small businesses" project. The questionnaire surveys were Korean Occupational Stress Scale(KOSS), and Legal Risk Assessment of Musculoskeletal Disorders(KOSHA CODE H-30-2003). As a result of the survey, scores of KOSS 8 sub-items except for job demand were similar to that of Korea workers. Prevalence of MSDs symptoms of small plants workers was high percent (44.9%). And the rate according to kinds of product was significant difference at neck (p<0.01), lumbar (p<0.01), and leg (p<0.01). There was no significant difference between view person sign of MSDs and non MSDs according to sex, year, the number of workers, working years, working time per one day, rest time per one day, and subjective working intensity, but there were significant difference between high stress group and low stress group about MSDs at interpersonal conflict(p<0.05). Job stress and MSDs were important factor to workers of small plants producted agricultural products. Therefore, starting a business with small plats, workers consider interpersonal conflict and body part showing MSDs.
