Objectives: The purpose of this study is to garner useful information through a comparative analysis of health behaviors and health states between the young-old and old-old elderly in a rural Korean area. Methods: We define the young-old elderly as those 65 to 74 years of age, and the old-old as those over 70. The survey was administered in October and November of 2009 at senior citizen centers in Sangju City, Kyongsangbuk-do, South Korea. The number of subjects surveyed approximated the demographics of the aged population of the administrative district of centers of 24 eup, myeon, and dong. Results: Compared with the young-old elderly, the old-old were vulnerable to population sociological characteristics. While there were many cases of contraction of diseases, only a small percentage of old-old elderly were engaged in regular exercise. In addition, the old-old elderly lagged behind the young-old in terms of physical activity, mental and oral health, hearing, and vision. Conclusions: The vulnerability of the old-old elderly in terms of physical and mental health needs to be acknowledged as various characteristics of the elderly that appears according an age group. A variety of disease prevention and health promotion programs that focus on the health behavior and status of the young-old and old-old elderly need to be developed and put into practice.

The present study was performed to investigate the patterns of appearance of lectin in trachea of fetuses of 60, 90 and 120 days old and neonates of Korean native goat. Carbohydrate markers were used in histochemistry for the determination of the lectin by staining of avidin-biotin-peroxidase complex(ABC), and the markers consisted of biotin-labeled concanavalin A(Con A), dolichos biflorus agglutinin(DBA), rincinus communis agglutinin(RCA-I), ulexeuropalus communis agglutinin(UEA) and wheat germ agglutinin(WGA). 1. The Con A-binding reactions appeared moderately on the apical surface of the tracheal epithelia in 60 days old fetuses, and the reactions were similar on the tracheal epithelia and glands in 90 and 120 days old fetuses and neonates. 2. Reaction of the DBA appeared as the strongest meanwhile the DBA-binding reactions were determined strongly on the apical surface of the tracheal epithelia in the 60 days old fetuses. Reaction for the DBA on the tracheal epithelia and glands of 90 and 120 days old fetuses and neonates were in same manner. 3. The RCA-I-binding reactions appeared very strongly on the apical surface of the tracheal epithelia in 60 and 90 days old fetuses. Reaction to the RCA-1 appeared moderately on certain apical surface of tracheal epithelia and glands in 120 days old fetuses and neonates. 4. No reactions provoked for the UEA in trachea of 60 days old fetuses and neonates, but the UEA-binding reactions appeared moderately in the tracheal epithelia of 90 days old fetuses and weakly in 120 days old fetuses. 5. The WGA-binding reactions appeared very strongly on the apical surface of the tracheal epithelia in 60 and 90 days old fetuses, and moreover, the reactions were determined on the luminal surface of the tracheal gland in 90 days old fetuses. On the other hand, goblet cells of the tracheal epithelia and glands in neonates reacted moderately to the WGA.

This study examined the caponization effects on the muscle characteristics (quality and quantity) of caponized male chickens fed before or after sexual maturity. Healthy and uniform Single Comb White Leghorn chickens were caponized at 3-week-old. Feeding was conducted until 16-week-old in trial 1 or from 12-week-old to 26-week-old in trial 2. Ten sham operated male chickens (Sham) were also assigned to each trial as the control group. Chickens used in both trials were housed in individual cages with each chicken representing one replicate. The results showed that early caponization (3-week-old) significantly increased (p<0.05) body weight and pectoral major muscle weight and percentage at 16-week-old compared to the Sham in trial 1. Caponization significantly increased (p<0.05) the protein content of the pectoral major muscle, but decreased (p<0.05) the ash content. Late caponization (12-week-old) significantly decreased (p<0.05) the ash content, myofibrillar ATPase activity and emulsification capacity of the pectoral major muscle in mature capons (26-week-old) compared to the Sham in trial 2. Early caponization (3-week-old) only increased the weight and protein content of the pectoral major muscle with decreased ash content in 16-week-old capons. Late caponization (12-week-old) showed no affects on pectoral major muscle quantity, while it decreased the ATPase activity and enhanced the emulsification capacity in mature (26-week-old) capons. Hence, the muscle quality improvement was shown as capons were fed to sexual maturity.

The purpose of this study is to examine the factors affecting the baby boom generation's preparation for old age, and based on that, it will provide foundational data to improve the baby boom generation's preparation for life in old age. According to the study results, with regard to their socio-demographic characteristics, their sex, age, health conditions, average monthly income, attitudes to old age, and anxiety about aging may have significant effects on their preparation for old age. In other words, the degree of preparation for old age is higher in women than men, those who are older, those having better health conditions, those with higher average monthly income, and those with better attitudes to old age, and those whose anxiety about aging is lower. Based on the above study results, the paper intends to make the following political suggestions: first, it is needed to develop preparation for old age services appropriately for each generation's needs and characteristics in consideration of their socio-demographic characteristics. Second, it is necessary to provide education for preparation for life in old age by steps and change their consciousness to enhance their attitudes to old age. Third, it is needed to develop and distribute a variety of mental health programs that can lower their anxiety about aging.

The morphological studies on the rectal development in the 60-, 90- and 120-day-old fetuses and neonates of Korean native goats were investigated by light microscopy and scanning electron microscopy. The rectal wall appeared to be differentiated into the epithelium, lamina propria, tunica muscularis and serosa in 60-day-old fetus. The rectal epithelia were stratified in some areas and simple columnar in others at 60- and 90-day-old fetuses but was only observed simple columnar epithelium at 120-day-old fetus. The goblet cells and the intestinal glands appeared in the rectal mucosa at 90-day-old fetus and gradually increase in number during gestation period. The rectal villi appeared at 60-day-old fetus and increased in length and width until 90-day-old fetus but the villi appeared to be shorter and degenerated after 120-day-old fetus. Only the rudiment trace of the villi remained at birth. The tunica muscularis of the rectum were continuously developed during gestation period. The inner circular and outer longitudinal muscle layers of rectum were observed in the 120-day-old fetuses. Under scanning electron microsoopy, the rectal villi appeared at 60-day-old fetus. The pentagonal/hexagonal microridges and numerous microvilli were observed on the luminal surface of rectal wall. Low and thumb-like rectal villi were developed at 90-day-old fetus. The rectal villi became degenerated after 120-day-old fetus. Only the rudiment of villi was remained at birth. Many circular folds were well developed. Opening portions of intestinal glands appeared like slot.

The purpose of this study was to examine the effect of treatment when the V{\ddot{o}}jta therapy applied to the infant with central coordination disturbance in early stage. The subject were 10 cases : each one with the V{\ddot{o}}jta therapy applied to the group of the infants before 6 months old and the group of the infants over 6 months old. When the V{\ddot{o}}jta therapy was applied I analized the papper which was written about the infants who were diagnosed as moderate CCD and divided two groups which were the infants before 6 months old and the infants over 6 months old. These collected data were analyzed by using t-test. The results of study were as follow; 1. When I compared the locomotion stage after the V{\ddot{o}}jta therapy. t-test showed significant differences. The group of infants before 6 months old had the result 7 to over stage 7 and the group of infants over 6months old had the result 2(p<.05). 2. When I compared the result of the postural reaction after the V{\ddot{o}}jta therapy, 1-test showed significant differences. The group of infants before 6 months old had 6 cases was normalizes and the group of infants over 6 months old had 1 case was normalized(p<.05). 3. When 1 compared the duration of the V{\ddot{o}}jta therapy between the group of infants before 6 months old and the group of infants over 6 months old. t-test showed significant differences. The group of the infants before 6 months old had 5 cases for 1-6 months and 4 cases for 7-15 months, 3 cases for 16-24 months and the group of infants over 6 months old had 6 cases for 7-15 months and cases for 16-24 months, 1 case for 25-30 months(p<.01).

A vast amount of materials-such as prints, woodblock prints, manuscripts, old novels, and letters-written in old Korean and using old grammar and/or obsolete characters, are collected in many institutions, including the Jangseogak at the Academy of Korean Studies. Digitization of these texts has required a prolonged manual inputting process. Individual researchers, who majored in old Korean, have read and typed the characters into electronic documents, which depends upon individual skill, effort, and approach, and is particularly limiting because none can be significantly increased. To date, only a small proportion of the old Korean document collections, currently kept in storage, have been digitized and made available to the public. Even the electronic formats of the texts prove difficult to displaying correctly, due to the incompatibility between the old Korean characters and the character set on today's electronic devices. To improve the techniques and efficiency of digitizing old Korean texts, it is necessary to develop optical character recognition (OCR), which will analyze images of old Korean documents, as well as input, display, and storage methods.

To evaluate an effect of growth periods on the bromobenzene-induced liver damage, bromobenzene was administrated to 5-week-old rats and 10-week-old rats pretreated with bromobenzene 5 times every other day for 10 days and then the animals were sacrificed. The results were obtained as follows; The increasing rate of serum levels of alanine aminotransferase, xanthine oxidase activity, hepatic lipid peroxide contents, liver weight per body weight (％) and decreasing rate of hepatic contents of protein to each control group were higher in 10-week-old rats than 5-week-old rats by the pretreatment of bromobenzene. According to the above results, 10-week-old rats indicated more severe liver injury than 5-week-old those in case of bromobenzene pretreatment. On the other hand, hepatic aniline hydroxylase activity was more increased in 10-week-old rats than 5-week-old rats both in control and bromobnezene pretreated rats where as the reverse in hepatic glutathione S-transferase. In case of hepatic GSH determination at the intervals of 2, 4, 8, 24 hours throughout 24 hr after administration of single dose of bromobenzene to 5-week-old and 10-week-old rats both in control and bromobnezene pretreated, the rate of GSH utilization was lower in 10-week-old rats than 5-week-old rats. In conclusion, from the above experimental, it is deduce that the 10-week-old rats showed more severe liver injury than 5-week-old rats by the bromobenzene treatment because the disposal ability of bromobenzene in liver was lower in 10-week-old rats than 5-week-old rats.

The purpose of this study is to make a model of Family Life Cycle in Korea now. Answers to a questionnaire were collected from 724 housewives in Seoul area, 232 housewives in big cities, 203 housewives in small cities. The questionnaire contained 10 items about family situations,. Analyzing method employed for modeling to family life cycle are frequency, percentage, X2 -test . Results and findings are as follows; 1) The mean of first marriage age is 22.4yrs old. 23.5yrs old is the result of statistical materials published by E.P.B. 1975. The age of first marriage is higher according to the age, education & residential area. 2) The mean of first baby bearing age is 24.2 yrs old (generally 1 year after marriage). This age is the same as the result of statistical materials published by E.P.B. 3) the mean of last baby berating age is 32.6 yrs old compared to the E.P.B. statistical materials 3 yrs. low. This age is very different according to the age, education & residential area. 4) The mean of first child marriage age is 46.4 yrs old compared to the E.P.B. statistical materials 2.5 yrs old low. 5) the mean of last marriage age is 52.7 yrs old. this age is also 2.3 yrs low compared to the result of E.P.B. materials. 6) The number of child & interval is quite different according to the result of family planning generation of not. 7)According to the wife's employment, it does not show and difference. 8)The result of analyzing by F.L.C.,, we don't have launching stage & middle age stage apparently. So, we can make model of F.L.C. in Korea as follows (it will be change). 1) Establishment stage; from marriage to first baby born (23yrs old -24yrs old). 2) Child bearing & rearing stage; form first baby born to first child enter primary school(24 yrs old-30 yrs old). 3) Families with children's education stage; from first child primary school to high school graduation (30 yrs old-42yrs old) 4)Families with adult children stage; form first child got army college or stay at home(42 yrs- 48 yrs old). 5)Families with children's marriage stage; from first child marriage to last child marriage (48yrs old-57yrs old). 6) Aging stage; from last child marriage to self dying.
