고령화는 국가사회적 최상위 현안문제 (National Agenda)의 하나로, 최근 출산률 저하와 수명 연장에 따라 점차 심화되고 있다. 이는 이미 퇴행성 척추 질환 및 관련 수술이 큰 폭으로 증가되는 현상으로 나타나고 있다. 따라서 고령화 사회를 대비하고 노령 인구의 삶의 질 향상을 위해, 노령 척추 질환에 대한 적절한 진단과 치료, 재활에 도움을 줄 수 있는 가상 척추의 개발이 절실히 요구된다. 본 논문에서는 국가문제해경형 연구사업(NAP)의 일환으로 가상 척추의 기반이 될 인체 척추 정보 데이터베이스를 구축하고 관리하는 시스템을 소개한다.

New Dietary Reference Intakes (DRIs) forthe United States and Canada have recently been set for both macronutrients and micronutrients, and are likely to be of interest to health professionals in Korea as well. DRIs are now available for nutrients that did not have Recommended Dietary Allowances set in the past (amino acids, n-3 and n-6 fatty acids, total fiber, added sugar, choline, boron, nickel, and vanadium). Furthermore, the units for the DRIs do not always match those traditionally carried on food composition tables (FCTs). FCT developers will also need to consider carrying new variables to allow the calculation of folate intake in $\mu$g of dietary folate equivalents, vitamin E intake as mg of a-tocopherol (not as mg of a-tocopherol equivalents), and vitamin A intake as $\mu$g of retinol activity equivalents (not as $\mu$g of retinol equivalents). Because the new recommendations for upper levels of intake sometimes refer to a specific form or source of a nutrient, nutrients occurring in foods must be separated from added or supplemental forms for vitamin E, niacin, and folate; pharmacological magnesium must be carried as a separate variable; and preformed vitamin A must be separated from vitamin A from carotenoids. For more information on the DRIs, see: www.nap.edu.

Morningness-Eveningness Questionnaire (MEQ) of Horne & Ostberg(1976) was translated into a Korean version, and MEQ and life habit inventory was administrated with approximately 900 university students. The distribution of MEQ score was normal. Arising time and bedtine for weekdays and holidays came in the order of morning type, intermediate and evening-type. And the deviation for the evening-type was greatest. Also, the deviation of sleep length for the evening-type was greater than the morning- type. There were tendencies that the bed time and arising time of the male were slightly later than those of the female, and the sleep length of the male was a little longer than that of the female. It also appeared that the arising time was later in the male who completed the military services than those who did not in the chronotype. And the sleep length of the non-served male was longer than that of the served one. Such tendencies noticeably appeared especially the evening-type. The evening-type was subject to heavy variability in bedtime. arising time, and sleep length. The sleep latency of the evening- type was longer and mood on arising was worse. And the ratio of nap or light sleep was higher in these subjects than in others. These results suggested that evening-type students had more irregular and/or flexible sleep-wake habits than the morning-type.

The copolymerization of N-acryloylpyrrolidone and acrylonitrile was performed in N,N'-dimethylformamide at 50$^{\circ}$C and monomer reactivity ratio was obtained by using IR working curve and Fineman and Ross equation. ($r_1$ = 0.43, $r_2$ = 1.56) It is found that resulting copolymer is good polymeric initiator for anionic graft copolymerization of 2-pyrrolidone. Graft copolymers with polybutylamide (nylon-4) grafts onto poly(NAP-Co-AN) backbone were synthesized and the various effects on the graft copolymerization of 2-pyrrolidone were examined. The rate constants ($K_p$) of graft anionic polymerization at 40 and 50$^{\circ}$C were 2.82${\times}$10 and 2.93${\times}$10(l/mole, min), respectively.

Purpose: The study compared the rest-activity rhythm and sleep pattern of elderly with young group. Methods: The subjects were 22 over than 65 years old and 23 under 65 years old. An actigraph, sleep diary, Pittsburgh Sleep Quality Index and Insomnia Severity Index scale were used as measurement tools for this study. The data were analyzed with $x^2$, Lamda test, t-test and correlation with SPSS 15.0 program. Results: The elderly had lower curve than the young group in rest-activity rhythm on each time zone. In particular, the elderly group had lower rest-activity rhythm curve of 8, 9, 14, 18, 19, 20, 21, 22 and 23 time zone than those of young group. Sleep pattern had statistical difference in the total sleep time, PSQI and insomnia. Total sleep time of elderly had lower score and PSQI and Insomnia had higher score than young group. Age had correlation with rest-activity rhythm, sleep efficiency, PSQI and insomnia. Conclusion: Rest-activity rhythm of the elderly showed an increase in activity in the early morning because of earlier get up than the young group and an decrease in activity in the afternoon because of taking a nap at this time. Elderly sleep was that total sleep time increased but sleep efficiency decreased and insomnia intensified. This sleep pattern was related to age and rest-activity rhythm.

Nowadays, digital map plays a role as a container of spatial database.'there have been many researches concerning the improvements of the digital map accuracy. From the user's viewpoint, however, the quality level of digital nap is as important as its accuracy, because fitness-for-use is considered the most important factor to the users. This study aims to find the methodology for determining the grade nか digital map. To accomplish this, we propose two major stages. First, weight factors of the layers are given according to the importance of the functions which must be considered in digital map generation. Scond, weight factors of the components to evaluate the accuracy of the digital map are presented By scoring the components and by summing the scores, the method for determining fitness-for-use is developed.

Shoos-in in Nara of Japan has two kinds of Priest's robe(Kasa : 袈裟) ; one is Jiksung Kasa(織成袈裟), the other Janap Kasa(刺納袈裟). The former is listed as the 'Jiksung Kasa of tree bark color in seven stripes' in the Treasures Record(珍寶帳) of objects dedicated by Empress Komyo on the 21st day of the 6th month 756 A.D. The warp threads are brown and the weft threads are in groups of two in two colors-dark blue, green yellow and red. The latter is the so called Janap Kasa, of tree bark colors in seven stripes, that was also dedicated by Empress Komyo, 'Ja' means to stitch, and 'Nap' means to sew. It is made of patches of silk of various color, placed overlapping one another in patterns the resemble a mountainous landscape. All are stitched together in a continous quilt-like manner with purple threads. Japan has been under the strong influence of Korea Buddhism during the Nara period. Acording to Nihonki(日本書紀) and Sokunihonki(續日本紀), from 668 to 769 A.D., Japan has bought numorous objects including Buddhist utensils such as priest's robes and banners from Korea. Also during the same period Japan has perchased many kinds of dyestuffs and paint. So we can be certain that priest’s robes were imported from Korea like many other objects of Shoso-in.

We present an efficient exponentiation algorithm for a finite field $GF(2^n)$ determined by an optimal normal basis of type II using signed digit representation of the exponents. Our signed digit representation uses a non-adjacent form (NAF) for $GF(2^n)$. It is generally believed that a signed digit representation is hard to use when a normal basis is given because the inversion of a normal element requires quite a computational delay. However our result shows that a special normal basis, called an optimal normal basis (ONB) of type II, has a nice property which admits an effective exponentiation using signed digit representations of the exponents.
