In order to check ordinary trend of a research for old ages, it was collected and analyzed against old ages. Out of a research papers from 1995 to 2005 issued for 6 scientific journals in clothing and textiles areas which were listed on KOREA RESEARCH FOUNDATION. The results were as follows. First, the research papers for 11 years from surveyed scientific journals were totally 5,711 papers, and It were only 71 papers for old ages to be reviewed and surveyed, which slightly occupied 1.24% from whole papers. Second, yearly ranges of research paper against old ages were shown to be down-trend, as it recorded 2.75% in 1995, however it falls on 0.77% in terms of the increasing aspect of clothing and textiles research paper numbers. Third, a paper for each research areas ranged in turn, as clothing construction, fashion merchandising socio-psychology of clothing, etc. If we see in detail area, the research for somatotype and role occupied 37.4% from all researches against old ages. Accordingly it needs more various kinds of study. Fourth, The Koreav Society of Clothing and Textiles paper occupied 40.8% from whole scientific journals, which was obviously shown. Fifth, each sex distribution for researched old ages noted almost old women (77.5%), but cover 9.9% for old men. Therefore it required much more researches for old men, we thought.

This study analyzes how social environment influenced underclothes and characteristic which underclothes have is associated with the outer garment and the underclothes in the Middle Ages. As a result, 1 can get the next conclusion First, throughout the Middle Ages, body was involved with the sense of same and sin influenced by the religious austerity. This mentality was applied to the underclothes. As underclothes are not generally revealed, it is recognized to be not important but inefficient. Second, in the late Middle Ages, as the outer garment reveal the body line, the underclothes are affected by it. So men's and women's distinction in the outer garment is applied to the underclothes. In the second quarter of the 14C, class distinction and sexual attraction certainly present on the outer garment but are not applied to the underclothes. The conceptions that underclothes might express the spirit of the changing times, in sympathy with the outer garment, did not enter the medieval mind. Third, the function to protect the body is emphasized the underclothing in the Middle Ages, whereas it was important to identify rank sign in the history of underclothes. Throughout the Middle Ages the underclothing of both sexes is emphasized utilitarian in (unction rather than class distinction and sexual attraction. But women exposed their body line in thin chemise to represent sexual attraction in the late Middle Ages.

This study analyzes the characteristics of somatotype changes of girls from the ages of 13 to 18 that provide basic data on clothing construction for middle and high school girls. We use data obtained from body measurements of 1,590 adolescent girls 13 to 18 years of age provided in the 6th national anthropometric survey report. The differences among the age groups for 56 direct measurements were analyzed by ANOVA, and the structures of the differences by SNK (Students-Newman-Keuls test) were analyzed. The two major growth ages were 'ages 13-14' and 'ages 15-16'. The first major growth ages focused on all measurement items of height, length, circumference, breadth, depth and other items. The second one focused on measurement items of height and length of torso, circumference, and breadth of lower body. The major growth pattern of the age groups was 'ages 13<14&15<16&17&18' which appeared focused on the height and length items of upper body and torso, the width items of lower body and the circumference items of upper body and lower body. The measurement items of front length like waist front length, N.P. to B.P to waistline, N.P. to B.P., and B.P. to B.P. showed the growth pattern for 'ages 13<14<15<16<17&18'.

Determining age structure of the population of an endangered species is critical because it could provide basic information about population dynamics. In this study, we assessed the possibility if the growth lines on dorsal scutes of the national monument as well as endangered Reeves' turtle (Mauremys reevesii) can reliably estimate actual ages of the 100 turtles of which actual ages were known and have been housed in Seoul Zoo. We counted the number of growth lines on the first four dorsal scutes and the first left and right lateral scutes of each turtle and compared those with their known actual ages. Ages estimated by the growth lines were overestimated at between 1 and 5 actual ages, but underestimated at between 6 and 9 actual ages, indicating that age estimation using growth lines is only partially applicable at actual ages of less than 6 years old. In addition, using length and width of turtle's dorsal plates, we produced growth curves with equations to estimate actual ages of females combined with juveniles, but its application to estimate actual ages was not reliably possible because all subject turtles which used were at relatively young ages. In conclusion, when estimating actual ages of Reeves' turtles using the number of growth lines on the dorsal scutes, it is recommend to use minimum values at less than 6 lines, but use maximum values at more than 7 lines. As the first study which estimated actual ages of a turtle species using growth lines on the dorsal scutes in Korea, our results could be useful to estimate ages of the endangered Reeve's turtles in the field although its application might be limited.

The corneal structure and function changes somewhat with aging. We were performed the analysis of women college students on the base curve, power, and astigmatism axis of the cornea by keratometer. All women subjects were between the ages of 19 and 20 years. On the corneal base curve. the right eye of the ages of 19 was 7.64 mm in vertical and 7.81 mm in horizontal. But, the left eye was 7.65 mm in vertical and 7.83 mm in horizontal on the other hand, the right and left eye of the ages of 20 was 7.72 mm in vertical and 7.75 mm in horizontal. On the corneal diopter power, the right eye of the ages of 19 was 44.21 diopter in vertical and 43.32 diopter in horizontal. But, the left eye was 44.23 diopter in vertical and 43.24 diopter in horizontal. On the other hand, the right eye of the ages of 20 was 43.67 diopter in vertical and 43.62 diopter in horizontal. But, the left eye was 43.73 diopter in vertical and 43.6 diopter in horizontal. According to the corneal astigmatism axis style, the right eye of the ages of 19 have 83% positive for with the rule astigmatism, and 16% positive for against the rule astigmatism. But, the left eye of the ages of 19 have 86% positive for with the rule astigmatism, and 12% positive for against the rule astigmatism. On the other hand, the right eye of the ages of 19 have 56% positive for with the rule astigmatism, and 44 % positive for against the rule astigmatism. But, the left eye of the ages of 20 have 56% positive for with the rule astigmatism, and 41% positive for against the rule astigmatism. According to the diopter power of corneal astigmatism. The right eye of the ages of 19 have 36% positive for behind 1 diopter and left eye have 31%. But, the right and left eye of the ages of 20 have 37.5%. The right and left eye of the ages of 19 have 42% positive for 1 diopter, and the right eye of the ages of 20 have 34.4% positive for 1 diopter and the left eye have 43.8%. The right eye of the ages of 19 have 12% positive for 2 diopter and left eye have 22%. But, the right eye of the ages of 20 have 15.6% positive for 2 diopter and the left eye have 12%. The right eye of the ages of 19 have 4% positive for 3 diopter and left eye have 3%. But, the left eye of the ages of 20 have 3% positive for 3 diopter and the left eye have 6%. On the other hand, the right eye of ages of 19 have 6% positive over 4 diopter, and the left eye have 2%. But, the right eye of ages of 20 have only 9% positive over 4 diopter.

On the basis of the study intended to research by crosssectional study keeps pace with semilongitudinal study the growthaccelerating phenomena that Maximum Growth age in teenager's body-height. By the random sampling method, the subject of study are 12659 persons(male; 6355, female; 6304) that they are from 7 ages to 17 ages in the whole country including the rural community. The measurement period passed three month days, the statistical data became electronic data processing system with computer. The other side, body-height and MGA of Koreans who had been for during the period from 1925 to 1966 proved transition of the growth-accelerating phenomena by research data reported between 1913 and 1983. The results are as follows; 1. The Growth and Development-Value of Body-height An age bracket the growth and development-value of body-height were, respectively, male is $123.88{\pm}5.05cm$ and female is $123.29{\pm}5.54cm$ for 7 ages group. these indices increased with age. the top-value reach, respectively. $169.08{\pm}5.62cm$ and $157.57{\pm}6.13cm$. The intersecting ages of male and female were the age $8.5{\sim}12.5$, during these periods, female excelled male but after these periods, male excelled female again. In case of body-height, MGA's are 7.0cm for male between 12 and 13 ages, and 7.01cm for female between 8 and 9 ages. As a rule, body-height of male excelled female but intersection phenomena of male and female appeared between 8.5 and 12.5 ages. By reginal groups, it is most prevailing is Seoul, and medium size cities and rural community rome in order. By regional groups, intersection phenomena of male and female are. a region of Seoul; $$8.5{\sim}11.5$$ ages a region of Daejeon; $$7.5{\sim}9.5$$ ages rural community; $$11.5{\sim}14.5$$ ages the whole country's average; $$8.5{\sim}12.5$$ ages By regional groups, the rate of maximum increase in a year are a region of Seoul; male is 7.23cm as 13 ages female is 7.65cm as 9 ages. a region of Daejeon; male is 7.85cm as 11 ages. female is 8.39cm as 9 ages. rural community; male is 7.65cm as 14 ages. female is 6.25cm as 12 ages. the whole country's average; male is 7.0cm as 13 ages. female is 7.01 as 9 ages. 2. Maximum Growth Age (M.G.A.) By reginal groups, maximum Growth Age's are as below in a region of Seoul, MGA's are 12.63 for male and 9.01 for female, which shows that MGA for female appears about 3.5 years earlier than that for male. In a region of Daejeon, MGA's are 9.20 for male and 8.93 for female, which. show that they are all much the same in M.G.A. In rural community, MGA's are 14.00 for male and 11.89 for female, which shows that MGA for female apperars about 2 years earlier than that for male. In the whole average, MGA's are 13.01 for male and 8.97 for femal, which shows that for female appears about 4 years earlier than that for male. For boy, M.G.A. shows fastest-growing in Daejeon, and Seoul and rural commonly come in order. For girl, It shows equal growth in Seoul and Daejeon, rural community comes later. 3. The M.G.A's in body height of male are respectively the age 15.02 in 1913, 14.23 in 1956, 13.86 in 1967, 13.62 in 1975, and 12.82 in 1981, while those of female are the age 12.0 in 1940, 11.52 in 1965, 9.53 in 1975, and 11.16 in 1980; these data show that the MGA of the Koreans has been getting younger. 4. The equation of linear regression of all the MGA's in body height are as follow; Male: Y(M.G.A)=$-0.020{\times}$ (the year)+15.19: female:Y(MGA)=$-0.028{\times}$(the year)+13.2549. 5. The corelation of all the MGA's in body height are as below; male; r=-0.329 female;r=-0.252 6. From the transition of the growth-accelating phenomena in 1980 we can capture the fact that the MGA's has been getting younger by 0.2 year per 10 years. 7. The MGA's in bodyheight are shown in table 4... 8. The future growth-accelating phenomena in body height are expected to show the similar tendency like that of the past, in 1910's but it should by more precisely reviewed after investigating the phenomena of the years directly ahead.

An 80% EtOH extract and the solvent fractions of the seeds of Cornus officinalis were evaluated for their inhibitory activities against advanced glycation end products (AGEs) formation and AGEs-induced protein cross-linking in vitro. In vitro assay for AGEs-bovine serum albumin (BSA) formation showed that the 80% EtOH extract, n-hexane, EtOAc, n-BuOH and water fractions significantly inhibited AGEs formation with observed $IC_{50}$ values of 1.13, 17.64, 1.52, 1.24 and $3.27{\mu}g/ml$, respectively. In indirect AGEs-ELISA assay, the 800% EtOH extract, EtOAc and n-BuOH fractions exhibited more potent inhibitory activity on AGEs-BSA formation than aminoguanidine, a well know AGEs inhibitor. Furthermore, the 80% EtOH extract and all the solvent fractions inhibited concentration-dependently AGE-BSA cross-linking to collagen. The 80% EtOH extract, EtOAc, n-BuOH and water fractions also had a breaking activity against preformed AGE-BSA cross-linking concentration dependently. Thus these results suggest that the 80% EtOH extract and fractions of the seeds of C. officinalis could be an inhibitor as well as breaker of AGE-BSA cross-linking.

Reactive oxygen species (ROS) and formation of advanced glycation end products (AGEs) play an important role in the pathogenesis of diabetic nephropathy by hyperglycemia. To find natural agents improving diabetic nephropathy, 63 natural resources which used to the treatment of diabetes mellitus in a folk remedy were investigated with an in vitro system employing radical scavenging activity and inhibitory activity of AGEs formation. In results, the extracts of Aspalathus linearis, Rubus coreanus, Rosa rugosa, and Epimedium koreanum significantly inhibited the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical with $IC_{50}$ values less than $10{\mu}g/ml$. The extracts of Zea mays, Cucurbita moschata, Cudrania tricuspidata, and Aspalathus linearis effectively reduced the formation of AGEs compared with the positive control $N-acetyl-_L-cystenine$ (NAC) and aminoguanidine (AG). In addition, the extracts of Aspalathus linearis, Commelina communis, Cornus officinalis, and Lespodeza cuneata showed the all inhibitory activity against DPPH radical and AGEs formation. Also, these resources definitely showed the radical scavenging activity against peroxynitrite $(ONOO^-)$ and hydroxyl radical $({\cdot}OH)$ relating to high glucose-induced ROS production. Thus, these results suggest that some natural resources may regulate the initiation and progression of diabetic nephropathy through inhibition of ROS production and AGEs formation.

K-Ar age determinations were carried out on muscovite and other gangue and wallrock alteration minerals from seventeen mineral deposits in the Taebaeg mountain district. Tin deposits give the ages of 1792 Ma and 158-127 Ma, whereas tungsten-molybdenum deposits give the ages of 1520-1480 Ma. 173-168 Ma and 84-81 Ma. Polymetallic mineral deposits. gold-silver deposits and sericite deposits yield the ages of 98-52 Ma. 93-75 Ma, and 202 Ma, respectively. Mineralization ages for each genetic type of deposits in this district can be summarized as follows; pegmatite deposits. 1792 Ma ; pegmatite-hydrothermal deposits. 1526-1480 Ma ; greisen deposits. 157-127 Ma ; skarn deposits, 98-73 Ma and 52 Ma ; hydrothermal deposits, 202-168 Ma and 93-76 Ma. Present results together with data available in the literature reveal that five distinct mineralization ages can be recognized in this district ; (1) 1792 Ma, (2) 1526-1480 Ma, (3) 202-127 Ma. (4) 98-73 Ma, (5) 52 Ma, These age data are similar to the reported radiometric age data of igneous rocks in this district except for two ages such as 2154-2084 Ma and 880-738 Ma.
