Maternity means all the women who are capable to conceive. In the aspect of health and medical care. however. it means the women who are now in pregnancy or have already given birth to a baby or are in a period of being recoverd from physiological changes occurred by pregnancy. According to the rapidly changing social structure. both the Quality and Quantity of the capacity of childbirth experienced by women are changing. Our society. having established a great economical growth by virtue of the highly developing and growing industrialization and urbanization. stimulates the women's advance into society and thereby increasing the number of employed women. When the women's participation in society is increased. their age of marriage is also affected. Which means there are a decrease of the capacity of childbirth in terms of quantity and a trend for women to have less children and to deliver a baby in their old age in terms of quality. On the contrary. since the number of multipara who want to have a baby in their old age is increasing. as a counter functional effect to the political project of decrease of a birth rate. concern has been focussed on childbirth in old age in the present study. And also such kind of the childbirth may be danger to the health of both mother and baby. Therefore the present study intended to provide some basic data of health education in the part of the health management of both mother and baby in the general hospital. based on understanding the realities of childbirth in. old age and things related to them. To achieve such a purpose of the present study. an analytical study by means of SPSS. was done using the data of 269 clinical records on both the newborn .babies and their mothers who had been supported by public general hospitals located in Seoul for 3 years from Jan. 1. 1991 to Dec. 31. 1993. Some significant results from the analytic study are as follows: 1. It appeared that the average age of normal. natural delivery was 33.8 years old and the average age of delivery through the cesarean operation was 35.4 years old. 2. It appeared that danger factors to childbirth women were types of the delivery and placental extrusion and danger factors to newborn babies are not so outstanding. 3. It appeared that the variables of the childbirth capacity which showed a significant difference according to each age group of women were the number of pregnancy. number of still birth, and number of existing children. That is. the age group of 'more than 35 years' had more frequency of experience In all 3 variables than the age group of 'less than 35 years'. 4. It appeared that the variables of the childbrith capacity which showed a significant difference a according to the sex of a newborn baby were number of pregnancy, number of still birth, and number of existing children. That is, the age group of 'more than 35 years' had more frequency of experience in all 3 variables than the age group of 'less than 35 years'. 5. It appeared that the health index of newborn babies which showed a significant difference was only 5 minute APGAR. That is, the health index 9.46 in the age group of 'more than 35 years' was less than an index of 9.72 in the age group of 'less than 35 years'. 6. Since a counter correlation of -0.10, as Pearson Correlation Coefficient, was showed between the age of childbirth mothers and the weight of newborn babies, it indicated that the higher age of childbirth woman, the lesser the weight of newborn baby. 7. It appeared that the number of women who had confirmed the sex of their baby before their delivery were 45 women, $67.2\%$ of total 67 women who had delivered a baby. and the expected sex by women in childbed was male with $73.1\%$ of total childbirth women expecting male birth and with their expression of feeling of female delivery. very regretful' by $39.3\%$ of total childbirth women. The results as shown above may indicate that instead of the possibility of danger to both the mother delivering a baby in old age and the baby delivered, the expectation of getting a son motivates childbirth in old age. As a conclusion, in a dimension of general hospital as well as national reform. it is required that a program of health education for childbirth in late maternal age have to be developed in the part of the health management of both mother and baby in the near future.

This study investigated the physicochemical properties and antioxidant activity of vinegar added with different levels (0%, 1%, 3%, 5%, and 7%) of Akebia quinata fruit during two-step fermentation. The physicochemical properties of vinegar evaluated were pH, total acidity, alcohol, and total sugar and amino acid contents. The antioxidant activities were based on ABTS radical scavenging activity, SOD-like activity, and reducing power. During alcohol fermentation, total acidity and alcohol contents of vinegar increased, but total sugar contents decreased. During acid fermentation, total acidities of vinegar increased. Vinegar added with 7% A. quinata fruit showed the highest total sensory score. Total polyphenol contents of vinegar added with 0% and 1% A. quinata fruit were not significantly different. However, vinegar added with 3, 5, and 7% A. quinata fruit showed significantly higher total polyphenol contents of 136.6, 381.59, and 415.35 mg/100 g, respectively, after 13 days of fermentation. Further, total flavonoid contents of vinegar added with 0~7% A. quinata fruit significantly increased to 21.73, 15.79, 15.15, 26.19, and 26.87 mg/100 g, respectively, after 13 days of fermentation. In addition, tannin contents of vinegar added with 0~7% A. quinata fruit significantly increased to 0.2042, 0.2004, 0.1255, 0.1384, and 0.1255 mg/100 g, respectively, after 13 days of fermentation. Moreover, ABTS radical scavenging activities of vinegar added with 0~7% A. quinata fruit significantly increased to 5.87, 12.59, 25.63, 34.02, and 35.25, respectively, after 13 days of fermentation at a concentration of 5 mg/mL. Additionally, SOD-like activities of vinegar added with 0~7% A. quinata fruit significantly increased to 8.22, 17.49, 16.86, 16.89, and 15.68%, respectively, after 13 days of fermentation. Reducing power of 7% A. quinata fruit was 0.527 after 1 day and 1.539 at the end of fermentation. Our results demonstrate that antioxidant activity significantly increased during fermentation according to the content of A. quinata. Further, the total polyphenol, flavonoid, and tannin contents were shown to be closely related with antioxidant activities. Thus, A. quinata could be effectively used as a vinegar and functional food material based on its antioxidant activity.

Jocheong was prepared by adding Lentinus edodes extract to improve its quality and to give some functional properties. Contents of crude protein, ash and crude lipid were similar to those of control, while carbohydrate content was decreased. Total mineral content were $1,916.03\~2,674.24mg/kg$ that was no difference between test samples. From HPLC determination of free sugars, Jocheong was found to contain maltose as the highest sugar, followed by glucose and fructose. In amino acid analysis, seventeen amino acid were identified and quantified. Glutamic acid in Jocheong was major amino acid. The major fatty acids in Jocheong $(0\%,\;control)$ were linoleic acid, palmitic acid, oleic acid, myristic acid and caproic acid. There was no significant differences in fatty acid composition, pH and reducing sugar content among the Jocheong samples. The viscosity and solid contents tended to decrease with the addition of Lentinus edodes extract. Increasing the ratio of mushroom extract in Jocheong tended to decrease the lightness, yellowness and redness in Hunter's color value. Although sensory value decreased with increasing Lentinus edodes extracts, use of mushroom extracts (7: 3; saccharification liquids: Lentinus edodes extracts) is recommended for making Jocheong.

The aim of this study was to evaluate the effect of light quality using either monochromatic or combined LEDs on the growth and antioxidant accumulation of Agastache rugosa cultivated under hydroponics for 4 weeks. This experiment was performed in a controlled-environment room at $22{\pm}1^{\circ}C$ and $18{\pm}1^{\circ}C$ (day and night temperatures, respectively) and 50-70% relative humidity, with a provided photosynthetic photon flux density (PPFD) of $180{\pm}5{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ and irradiated with either monochromatic (W10 and R10) or mixed LEDs (W2B1G1, R3B1, R2B1G1, and W2B1G1) with a differing ratio of each LED's PPFD and fluorescent lighting (FL: control) with a 16/8 h photoperiod. Fresh and dry weights were highest for plants grown under the W2B1G1 treatment. A. rugosa grown with R10 had the greatest plant height but the lowest SPAD among all treatments. The concentration of rosmarinic acid in plants grown under W2B1G1 was significantly higher than that of plants grown under other treatments. Tilianin content was significantly higher in R3B1 than in the other treatments. However, whole-plant rosmarinic acid and tilianin content was the highest under the W2B1G1 condition. To cultivate A. rugosa in a plant factory, mixed-LED light conditions with W2B1G1 is considered to be more advantageous for the growth and antioxidant accumulation of A. rugosa. It is though that the total whole-plant antioxidant content is more crucial for commercial use; the present study demonstrates the potential to achieve higher content of functional materials in plants through the selection of light quality.

Aim of this study was to investigate the effects of different nutrient solutions and various light qualities generated by LED on the growth and glucosinolates contents of watercress (Nasturtium officinale) grown under hydroponics for 3 weeks. The seeds of watercress were sown on crushed rockwool media and raised them for two weeks. They were transplanted in a semi-DFT (deep flow technique) hydroponics system. A controlled-environment room was maintained at $20{\pm}1^{\circ}C$ and $16{\pm}1^{\circ}C$ temperatures and $65{\pm}10%$ and $75{\pm}10%$ relative humidity (day and night, respectively), with a provided photosynthetic photon flux density (PPFD) of $180{\pm}10{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ and a photoperiod of 16/8h. To find out the best kinds of nutrient solutions for growing watercress, Otsuka House 1A (OTS), Horticultural Experiment Station in Korea (HES), and Netherland's Proefstaion voor Bloemisterij en Gasgroente (PBG) were adapted with initial EC of $1.0-1.3dS{\cdot}m^{-1}$ and pH of 6.2, irradiating PPFD with fluorescent lamps (Ex-1). Either monochromatic (W10 and R10) or mixed LEDs (R5B1, R3B1, R2B1G1, and W2B1G1) were irradiated with a differing ratio of each LED's PPFD to understanding light quality on the growth and glucosinolates contents of watercress (Ex-2). Although significant difference in the shoot growth of watercress was not found among three nutrient solutions treatments, but the root fresh weight increased by 13.7% and 55.1% in PBG and OTS compared to HES, respectively. OTS increased the gluconasturtiin content by 96% and 65% compared to PBG and HES. Compared with the white light (W10), the red light (R10) showed a 101.3% increase in the shoot length of watercress. Increasing blue light portion positively affected plant growth. The content of total glucosinolates in watercress was increased by 144.5% and 70% per unit dry weight in R3B1 treatment compared with R2B1G1 and W10 treatments, respectively. The growth and total glucosinolates contents of the watercress were highest under R3B1 among six light qualities.

Lentinus edodes powder was added at 1-3%(w/w) to improve functional properties of jocheong. Content of crude protein, ash, crude lipids, total mineral, free sugar and reducing sugar increased with increasing amount of L. edodes powder, while viscosity and solid and carbohydrate contents decreased. Through amino acid analysis, 17 amino acids were identified and quantified, glutamic acid being the major amino acid. No significant differences were observed in fatty acid composition and pH between control and L. edodes powder-added jocheong. Addition of mushroom powder in jocheong decreased lightness, yellowness and redness in Hunter's color value. Sensor score of jucheong containing 1% of L. edodes powder was similar to that of control. Results showed jocheong containing less than 2% L. edodes powder gave highest scores in quality characteristics and sensory evaluation.

In this study, rice wine cakes (Jubak) was produced using with Astragali memvranaceus with excellent antioxidant and antidiabetic effects and produced. This Jubak was applied to improve the cookies of modern taste and well-being products. The cookies according to the different ratio (added 0-1.0%) of Astragali memvranaceus and investigated the physicochemical characteristics, sensory evaluation, DPPH free radical scavenging activities, polyphenol and flavonoid contents. There were little changes in pH and density. The hardness of all treated cookies increased with Astragali memvranaceus Jubak(AJ) containing of different moisture contents. In color, L and a values of most cases increased in most of the treatments, but b value was reduced. In the sensory evaluation, the flavor and total scores showed the highest in 0.5% AJ cookies. But the higher proportion of AJ cookies that had unique flavors and tastes, so the total acceptance score decreased. The polyphenol and flavonoid contents increased in the higher proportion of AJ. In DPPH free radical scavenging activities, the control (no Jubak added) was 44%, and containing of 1% AJ cookies showed 82%. In conclusion, our study suggests that 0.5% in addition of AJ increased positive attributes and functional to cookies.

'Manmibyeo', a new japonica rice cultivar, is a mid-late maturing ecotype cultivar developed by the rice breeding team of Department of Functional Crop, NICS, RDA in 2002. This cultivar was originated from the cross between 'Milyang 95' and $F_1$ of the cross between 'Bukrukbanna' and 'Milyang 95' in 1990/1991 winter season. It was selected by pedigree breeding method until F6 generation, and a promising line, YR14545-9-2-3-4, was advanced and designated as 'Milyang 162' in 1996. The local adaptability test of 'Milyang 162' was carried out at seven locations during 3 years in 1997, 1998 and 2002. It has about 86cm culm length and is lodging tolerant. This cultivar is susceptible to bacterial blight ($K_1$, $K_2$, $K_3$) and stripe virus, and moderately resistant to leaf blast disease. Milled rice kernels of 'Manmibyeo' is translucent with low amylose content in endosperm, clear in chalkiness and good at eating quality in panel test. The yield potential of 'Manmibyeo' in milled rice was about 4.46 MT/ha at ordinary fertilizer level in local adaptability test. This cultivar would be adaptable to the southern plain of Korea.

Chief Consultant Archives Government Archives & Records Service -table of contents- 1. Introduction 2. Relationship of Historical Studies and Archive 3. Relationship of Archives and Archives 4. Conclusion; Historians, Archives, and Archivists, and Their Roles This essay is mainly written for historians who may have "little or limited experience" in dealing with archives and archivists in their course of historical research. It may sound very ridiculous to say that "historians have little or limited experience" in using archives but it is also true that many Korean historians have depended on various compiled editions of historical materials or personally donated and/or collected materials when they do research, rather than they would visit archives and search for the materials by themselves. This is the main reason for that the public archives in Korea have not served historians well and effectively, and vice versa, that historians have not visited archives sometime with no knowledge of archives, and have not requested opening of archives for their research. It is a simple fact that historian's study depends on the records he/she uses. Without records, there should be no history. Use of archives for historical research is a common thing and a must in modern archives. Records are selected to be preserved in archives for their preservation as well as their future use. Who select the records as archives? Archivists do mostly. Then, what are the criteria for the archivists to chose records as permanent preservable archives? Answers to this fundamental question have been provided by many historians and archivists. The closest answer may be that selecting archivists would be better trained and equipped with historical research and knowledgeable of the major trends in historical research. With his/her own experience of historical research and tracing the trends of historical studies and materials used in the historiography, they could chose better and appropriate records for future use using their prudence and discretion. It also means that historians have had influence on archivists in their selecting archives by providing the theme and context of historical studies of the time. Though not necessarily becoming a historian themselves, selecting or appraising archivists should understand the process of creating the records and should know how they become archives. This is a precondition to become a good archivist. But that's not all. They must know how the archives are used and what archives are used for what purposes. Among many other roles of modern archivists, selecting and describing the archives are the foremost tasks of an archivist. Archivists therefore developed modern methods to select future archives based on functional analysis and records series concept rather than a record file or item as a unit of selection. Historians are users or consumers of the archives held in the archives building or repository. The quality of their study depends on the "quality" of the materials they use. With the help of archivists not to mention of reference service, historians owe much to archivists in having an access to the materials they need, intellectually and physically. Too many closed archives and too long closed archives in the archives repository would benefit neither historians nor archivists. However, archivists can mostly react only to archive requests and demands made by historians for more wide accessibility. Using the FOIA, as in the U.S., or the Information Opening Act, as in case of Korea, historians can promote the use of historical materials as well as promoting accountability and transparence for the benefit to society as whole. In this context, it is vary desirable to establish a close professional relationship between historians and archivists even in the age of information society. At present, historians need more understanding of operation and importance of archives while archives administration need to realize the potential archival demands from research community and civil movement for clean government.

The consumption of oats (Avena sativa L.) with high nutritional utility is accelerating due to the increased consumers' demand for functional foods. In Korea, naked oats are used as food, while covered oats are used for animal feed. However, it is difficult to distinguish naked oats from covered oats when the husk is removed from the grains by a special process. The present study was carried out to investigate experimental methods that would be beneficial in the segregation of different types of oats after husk removal. Grain quality-related biochemical compounds were analyzed in a bid to differentiate the oat dehulling characteristics. In addition, 61 SSR markers were examined for genetic relationship and variety identification of oats using five naked and seven covered oat varieties. Results showed that, the contents of protein, lipid, and ${\beta}-glucan$ were not significantly different among the oat varieties and this could not be used as an index for distinguishing oats husk character. However, in the fatty acid composition ratio,, naked oats had a higher ratio of stearic acid (C18:0) and oleic acid (C18:1) than covered oats, and covered oats had a higher ratio of linoleic acid (C18:2) and linoleic acid (C18:3) than naked oats. The assessment of SSR marker genotype revealed that 33 polymorphic bands among 12 oat varieties and 1 variety could be distinguished through the combination of polymorphic markers thus indicating the usability of these markers for variety identification in oats.
