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.

The studies were carried out on the correlation between microsomal lipid peroxidation level and drug metabolizing enzyme activities in rat liver microsomal suspensions on various ages (2-week-old, 2, 4, 8, and 12-month-old). The lipid peroxidation levels of liver homogenates tended to be elevated in a 4-month-old rat livers, but it was a little decreased in 8 and 12-month-old rat livers. The lipid peroxidation levels of microsomal suspension was not shown any significant differences by ages. Lipid peroxidation levels and microsomal cytochrome P450 and NADPH-cytochrome c reductase activity showed a direct correlation (r=0.72 and r=0.64), respectively. The activities of cytochrome P450-dependent aminopyrine-N-demethylase and benzpyrene hydroxylase in rat liver microsomes were increased by ages up to 8-month-old rats and maintained in 12-month-old rats. The correlation between lipid peroxidation levels and these cytochrome-dependent enzyme activities showed a high direct correlation (r=0.97 and r=0.81), respectively.

Microbial communities in mangrove forests have recently been intensively investigated to explain the ecosystem function of mangroves. In this study, the soil microbial communities under young (<11 years-old) and old (>17 years-old) mangroves have been studied during dry and wet seasons. In addition, biogeochemical properties of sediments and methane emission from the two different mangrove ages were measured. The results showed that young and old mangrove soil microbial communities were significantly different on both seasons. Seasons seem to affect microbial communities more than the mangrove age does. Proteobacteria and Chloroflexi were two top abundant phyla showing >15%. Physio-chemical properties of sediment samples showed no significant difference between mangrove ages, seasons, nor depth levels, except for TOC showing significant difference between the two seasons. The methane emission rates from the mangroves varied depending on seasons and ages of the mangrove. However, this did not show significant correlation with the microbial community shifts, suggesting that abundance of methanogens was not the driving factor for mangrove soil microbial communities.

Many housing alternatives and design guidelines for the elderly have been suggested along with the rapid increase of old persons. However, most of them focused on the spatial composition and fixtures. They do not address on interior style which affects on interior mood. The interior style is especially important to the elderly who spend most of their time in indoor space, such as housing unit or nursing home. On the base of these backgrounds, the purpose of this study is to examine what interior style of bedroom and living room where the elderly lives are and whether they are significantly different depending on their cognitive ages, or not. The subject were 202 old persons who lived in Busan. Their ages were more than 65 years. They were interviewed by using 3D images of bedroom and living room. Each one consisted of three interior styles; Korean traditional style, Western classical style, and modern style. The results were as followings; The interior style of bedroom and living room which the old persons lived were different depending on the elderly's cognitive ages. The younger the old persons' cognitive ages were, they lived in bedroom or living room of modern style. Also, the older their cognitive ages were, they lived in bedroom or living room of Korean traditional style. These results show that the cognitive age of the old persons affect the characteristics of interior design which they live. Also, it implies that the elderly are not one homogeneous group, but a heterogeneous one.

To use bamboo in the pulp industry, the anatomical characteristics of 60-day-old, 1-year-old, 2-year-old, and 3-year-old moso bamboo (Phyllostachys pubescens Mazel), and the characteristics of fiber and sheet of alkali pulp made of moso bamboo were investigated. Moso bamboo is composed of metaxylens and parenchyma cells in the inner part of the wall, and thick-walled small bundle sheathes near the outer walls. Moso bamboo showed the heterogeneity in anatomical structure. The longest fibers were shown in the middle part, and the widest width in the inner part. The lignin contents were 14.4% in 60-day-old bamboo, which was not lignified yet. The lignin contents in bamboo above 1 year were approximately 35%. The yields of alkali pulp of moso bamboo were in the range between 41 and 47%, and the yields tend to decrease with the increase of ages. The lignin contents of 60-day-old bamboo were 2.1% and those of bamboo above 1 year showed approximately 4% to 5% increment. The length, width, and curl index of fiber in alkali pulp appeared to be similar in all ages. However, coarseness increased slightly with the increase of bamboo ages. The distribution of long fiber was shown much in 60-year-old bamboo. The optical and mechanical properties of moso bamboo tended to decrease with the increase of bamboo age.

In order to know when the cumulus cells of mouse follicles get ability to expand in vitro, the oocyte cumulus complexes obtained from different growing ages of mice were cultured in the medium containing HCG and their rate of expansion were observed and at the same time their maturation rate was examined. The growth of follicles was also checked by histological method. It was impossible to isolate the oocyte-cumulus complexes from 13 or 15 days old mouse ovaries. The oocyte-cumulus complexes collected from 17 days old mouse were partially induced to expanded by HCG, and from 19 days, most of the complexes were induced to full expansion. The rate of cumulus cell expansion by HCG and the oocyte maturation increased steadly during the growing ages to adult. Thus, the time for follicles to get competence for expansion and maturation seems to be closely related. Antral follicles were appeared from 17 days old mice and Graafian follicles were seen from 21 days old mice. The competence for cumulus expansion increased during follicle growth up to 21 days old mice.

This study was conducted to improve the yield of mature oocytes from in vitro-culture of ovarian primary follicles by optimizing follicle retrieval from neonatal mice of different ages. Primary follicles of 75 to $99{\mu}m$ in diameter were collected daily from 7- to 14-day-old neonatal mice, and subsequently cultured in ${\alpha}$-MEM medium. Number of primary follicles isolated, growth of the follicle during in vitro-culture and maturation of intrafollicular oocytes were monitored. Overall, mean number of preantral follicles per animal was improved from 10.7 to 88.7 as the age of follicle donors was increased from 7 to 14-day-old. Number of primary follicles was increased gradually up to 11-day-old (35.7 follicle per an animal), then reduced to 29 in 14-day-old (p = 0.0013). More follicles retrieved from 10-day-old or 11-day-old females maintained their morphological normality at the end of primary culture than the follicles retrieved from 9-day-old. Of those cultured, primary follicles retrieved from 11-day-old mice yielded largest larger number of early secondary follicles than the follicles retrieved from in the other ages (39 vs. 13 to 29%). More than 3.3-times increase (0.86 to 2.86; p<0.05) in an average number of mature oocytes per animal was observed in the group of 11-day-old, compared with 9-day-old. However, no difference was found in the percentage of primary follicles developing into the pseudoantral stage (21 to 30%; p = 0.5222) and in the percentage of oocytes mucified (32 to 39%; p = 0.5792). In conclusion, a positive correlation between retrieval time and follicle growth was detected, which influences the efficiency to derive mature oocytes by follicle culture.

Anti-aging is one of the key words to have characterized Korean society, and Korean adults in their 40s and 50s are very interested in this word. In this study, their cognitive ages and body images which are expected to have been influenced by anti-ageing were determined and correlation between them was examined. A survey was conducted and 368 of 500 questionnaires were used in data analysis. Data were analyzed by descriptives, factor analysis, reliability analysis, correlation analysis, and multiple response analysis through SPSS 12.0. The results are as follows. First, the cognitive ages of Korean adults in their 40s and 50s showed to be 37.5 years old which are 9.1 years old younger than their average actual ages. Second, their attitudinal body images appeared to be composed of appearance orientation and appearance evaluation, and appearance orientation represented to be a little higher than appearance evaluation. In addition, it showed that the correlation between cognitive ages and the attitudinal body images was low and negative. Third, people in their 40s and 50s revealed to think good health and impression as ideal body images. It was found that they regarded a face as the most important body part for ideal body images and were sensitive of their weight. Forth, correlation between cognitive ages and variables of ideal body images was identified to be significant in 4 variables which are slender, shapely and slim figure and good body proportions. In conclusion, it was shown that Korean adults in their 40s and 50s recognized themselves to be 9.1 years old younger and, the younger they perceive themselves, the younger body images they want. Also, it could be confirmed that anti-ageing is a megatrend in Korean society.

Objectives The purpose of this research is to find out the relationship between Zema 21 and in body based on the Sasang Constitutional difference of children. Methods We collected 1050 children from 5 years old to 15 years old who had been tested for both Zema21 and Inbody in OO oriental hospital from the period of September 1, January 1999 to August 31, 2008. This research investigated the Constitutional differences based on the relationship between Zema21 and Inbody. Results 1. It turned out that the children's height does not have a significant relationship between their age and gender. 2. Generally, Taeumin's weights were significantly high than those of Soyangin's and Soumin's in certain ages in children over 9 years old and in all genders. 3. The percentage of the body fat in Taeumin were significantly high than Soyangin and Soumin in certain ages in children over 10 years old and in all genders. 4. Waist-Hip ratio in Taeumin were significantly high than Soyangin and Soumin in male over 10 years old and in female over 13 years old of children. On the other hand, there was no relationship to the Soyangin and Soumin. 5. The obesity degree in Taeumin were significantly high in all female and male who were over 10 years old. Soyangin were the next highest group and Soumin follows. 6. Body Mass Index in Taeumin were significantly high in all genders who were over 10 years old. The second is Soyangin, and the lowest groupis Soumin. 7. The Basal Metabolic Rate resulted as significant in all age, although this does not have any relationship between age and gender. 8. Abdomen out in Taeumin were significantly high in ages over 10 and genders. The second is Soyangin and the lowest is Soumin. 9. Hip circumference Abdomen out in Taeumin were significantly high in ages over 10 and genders. Specially, Taeumin shows highest value, then the second is Soyangin, and the lowest is Soumin who were over 12 years old. Conclusions The results of Inbody were not significant to the children who were under 9 years old. Taeumin became significantly fat after over 10 years old.

Background: Ginseng (the roots of Panax ginseng Meyer) is a well-known traditional Oriental medicine and is now widely used as a health food. It contains several types of ginsenosides, which are considered the major active medicinal components of ginseng. It has recently been reported that the qualitative and quantitative properties of ginsenosides found in ginseng may differ, depending on cultivation regions, ages, species, and so on. Therefore, it is necessary to study these variations with respect to cultivation ages and regions. Methods: In this study, 3-6-yr-old roots of P. ginseng were collected from three different cultivation regions. The contents of five ginsenosides (Rb1, Rd, Rc, Re, and Rgl) were measured by rapid resolution liquid chromatography coupled with quadruple-time-of-flight mass spectrometry. The Kruskal-Wallis Rank sum test and multiple t test were used for comparative analysis of the data to evaluate the dynamic changes in the accumulation of these ginsenosides affected by cultivation regions and ages. Results: The content and composition of ginsenosides varied significantly among specimens collected from different cultivation regions and having different cultivation ages. For all samples, the content of Rg1 and Re ginsenosides increases with age and this rate of increase is different for each sample. The contents of Rb1, Rc, and Rd varied with cultivation ages in samples from different cultivation regions; especially, Rb1 from a 6-yr-old root showed approximately twofold variation among the samples from three cultivation regions. Furthermore, the content of Rb1 highly correlated with that of Rd (r = 0.89 across all locations and ages). Conclusion: In our study, only the contents of ginsenosides Rg1 and Re were affected by the root age. Ginsenosides Rb1, Rc, and Rd varied widely with ages in samples from different cultivation regions.
