This study was conducted to investigate the recognition and uses of Angelica gigas Nakai. A survey methodology was employed consisted of 37.8% males and 62.2% females from the Seoul and Kyunggido area. The main results are as follows: The older generation have liked and eaten Angelica gigas Nakai rather than the young. The most popular reason provided for the preference of Angelica gigas Nakai was good health benefits. People indicating a dislike for Angelica gigas Nakai had little previous experience of eating this plant. The purchasing main place is appeared the supermarket and traditional market. Angelica gigas Nakai was acknowledged as having the following characteristics 'to do excellent nutrition' (3.82), 'natural food' (3.76), 'to doing for the anti-cancer and anti-oxidization' (3.70), 'good for anemia and women, diseases' (3.64), and 'good for anodyne and diuretic effect' (3.57), but was not associated with 'price is cheap' (3.02) and 'to difficult for buy' (3.10). Recognition and eating experience was low for Angelica gigas Nakai kimchi and rice bread, bread, sauce and healthy drink added with Angelica gigas Nakai, but the opinion of the taste appeared highly.

For the analysis of mortality differentials by socioeconomic factors based on death registration data, we have considered four variables : place of residence, educational attainment, marital status and occupation. The age range adopted were 5 to 64 years of age for place of residence, and 25 to 64 years of age for the other factors. The mortality differentials by socioeconomic variables were clear and in the expected direction: mortality levels among urban residents, better educated groups, and non- agricultural workers were lower than among the other sub- groups. The average mortality level in rural areas is much higher than in urban areas : the rural mortality levels were at least double the urban levels at ages below 40 years, but became smaller after age 40, and no clear differentials by urban I rural residence increased until 1974~76 for the both sexes, but since the then differentials have declined slowley for both sexes. This changing pattern of mortality differentials by place of residence can be explained by historical socioeconomic development : the development generally started in urban areas, and rural areas followed : in the course of socioeconomic development the differences between the death rates in the two areas became smaller and finally the mortality levels in the two areas became nearly the same, as is found in the developed countries nowadays. The inverse relationships between mortality and educational level became stronger between the periods 1970~72 and 1984~86, but showed the same atterns of mortality differentials in both period : larger differences among the younger age groups, and for males, than among the older age groups, and for females. The increasing mortality differentials in the fourteen-year period between 1970~72 and 1984~86 were caused by inadequate living standards of the non- educated, whose proportion in the total population, however, dropped sharply during that period. Also, the much lower proportions of low - educated groups or of persons with no formal education among males than females helped to establish the clearly pronounced differentials. The mortality differentials by marital status in Korea showed the usual pattern : the mortality rates of the married in each age and sex group were clearly lower than those of others during the fourteen-year period between 1970~72 and 1984~86. In Korean society which remotes universal marriage, the never married recorded especially high death rates, presumably mainly because of ill - health, but also possibly because of the stigma attached to celibacy. However, the mortality differentials by marital status changed with the changes in the proportionate distribution by marital status during the period : the differences between the death rates of the married and never married groups became smaller, the proportion of the never married group increased : in contrast, the differences between mortalities of the married and widowed / divorced / separated groups widened, with the decrease in the proportion of the later group ; this tendency was perticularly marked for females. Occupational groups also showed clear mortality differences : among four occupational groups mortality of males was highest among agricultural workers and lowest among 'professional, admi-nistrative and clerical workers, However, when the death rates were standardized by educational level, the death rates by occupation in age group 45~64 years were nearly the same (excet for the mixed group consisting of unemployed, students, military servicemen and unknown). Therefore, the clear mortality dfferentials by occupation in Korea resulted mainly from the differences in educational level between different occupation groups. Since socioeconomic characteristics are related to each other, the net effect of each variable was examined. Each of the three variables - ducational level, marital status and urban / rural residence affected significantly Korean adult mortality when the effects of the other variables were controlled. Among the three variables educational level was the most important factor for the determination of the adult mortality level. When male's occupation was added to the above three variables, the effects of occupation on adult mortality were notably smaller after control for the effects of the other three variables while the net effects of these three variables were nearly the same irrespectively whether occupation was included or not. Thus, the differences in educational level (mainly), place of residence and marital status bring out the clear differences in observed mortality levels by occupation.

Objective : The purpose of this study was to examine the relationship between bone mineral density (BMD) and the metabolic syndrome. Method : We conducted a cross-sectional study of 1204 adults(males: 364 females: 840) in a general hospital health promotion center. They were grouped into the normal and lower BMD group according to bone loss(osteopenia, osteoporosis), as determined by duel energy X-ray absorptiometery(DEXA). We analyzed the association between BMD and metabolic syndrome by multiple logistic regression analysis. After adjustment for age, weight, alcohol intake, smoking, regular exercise, regular intake of meals, and menopausal status, odds ratios for the prevalence of the metabolic syndrome by gender were calculated for lower BMD. Results : After adjustment for the effect of potential covariates, the prevalence of metabolic syndrome was associated with bone loss in men(p<0.001). If the odds ratio of normal group is 1.00, then that of the lower BMD group is 3.07(95% CI=1.83-5.16). The prevalence of metabolic alterations fitting the criteria of metabolic syndrome was significantly decreased in High BMI, Low HDL in men and in High BMI in women(p<0.05). Conclusions : This study shows that BMD was associated with metabolic syndrome. Further studies needed to obtain evidence concerning the association between BMD and metabolic syndrome.

Family meals are very important for physical and mental health of family mebers. The purpose of this study is to contribute to change the habitual and unconscious cooking methods of housewives into more scientific moth(Ids. In order to achieve this purpose, this study tried to find out the degree to which housewives applied their knowledge of nutition and foods to actual behavior in purchasing. A special form of questionaire was prepared and distributed to 502 housewives in Seoul from Feb.8th to 22nd in 1989. The results were as follows: 1. Mean (score) of their nutritional knowledge was 14 7; if seems to be comparatively higher. 2. When they purchased food materials, their husbands' favor was the first consideration. Particularly, freshness was the first considered in purchasing meat, fishes, fruits, and vegetables. And Nutrition was so in case of seaweeds, oil, and fat. 3. For the most part, they cook three or four Subsidiary dishes for a meal. If they cooked one or two they chose to cook vegetables. If three or four they added meat and fishes. If more than four, they used various food materials.

This study examines the hazard rate of reemployment by conducting the Cox regression analysis. In addition, two gender groups are subjected to comparative analysis to identify the effect of the factors related to the human capital and human capability perspective on reemployment. For this purpose, 1,871 cases are selected from the 5th year data from Korea Labor and Income Panel Study. The results of study are as follows. First, the factors of human capital, such as education, appropriateness of skill level, and job tenure hold negative impact on the probability of reemployment, while factors of human capability, such as basic learning ability, health insurance, social insurance, residential area(living in the Seoul metropolitan area) hold positive on the probability of reemployment. It is interesting note that there are different sets of factors that affect the probability of reemployment in the two gender groups. This trend is even more apparent in the case of factors that pertain to human capability. The results of this study imply that the factors of human capability, which stress the socio-institutional characteristics, should be considered as comparably significant compared to the factors that pertain to human capital when it comes to the estimation of reemployment. Also, results of this comparative study teach us that various perspectives, such as dual labor market theory and gender-segmented labor market theory, should be factored in for reemployment discussion as well. In conclusion, this research delivers several significant messages since it introduces the concept of human capability perspective, subjected to few empirical analyses in the past, and also heralds the way for comparative analysis on the impact of the factors pertaining to human capability on reemployment.

Parents in South Korea are known for their high level of educational zeal for their children. As a result, their children usually take extra classes in institutions as well as participate in other extracurricular activities such as sports and music. The purpose of this study was to examine the lifestyle and dietary behaviors of Korean elementary students involved in such activities. The total number of subjects was 550 fourth to sixth graders in elementary schools in Sejong, Korea. Of the total subjects, 88.0% were involved in extracurricular classes or other activities for an average of 7.34 hours/week. The subjects were assigned to one of four groups based on the degree of extracurricular activities: No extra-class (n=66), Low extra-class (1${\leq}$taking time<5 hours/week, n=118), Medium extra-class (5${\leq}$taking time<10 hours/week, n=184), and High extra-class (taking time${\geq}$10 hours/week, n=182). More subjects in the High extra-class group went to bed late (P<0.01), were under stress (P<0.01), and skipped breakfast, compared with those in the other groups. The ratio of students who answered 'I go to an institute without a meal' (P<0.01), 'I prepare a meal for myself' (P=0.053), or 'I eat out before going to an institute' (P<0.01) was higher in the High extra-class group than in the Low extra-class group. The frequency of eating fast food was higher in the High extra-class group, compared with the other groups. These results indicate that a high amount of extracurricular studies may have a negative effect on the children's lifestyles and dietary behaviors. Therefore, this study alerts parents to the potential harm of excessive extracurricular activities to their children's health.

This study was carried out to compare the storability of Salsola komarovi Iljin and Suaeda maritima L. Dum which stored at different storage temperatures in MA storage. These plants that had grown in greenhouse packed with $50\;{\mu}m$ ceramic film and then stored in $2^{\circ}C$, $10^{\circ}C$, and $25^{\circ}C$ temperature. The fresh weight loss both plants was less than 1% in all temperature treatments. The highest fresh weight loss showed at $25^{\circ}C$ among storage temperature treatments in Salsola komarovi Iljin between plants. The highest carbon dioxide contents in package showed at $25^{\circ}C$ among storage temperature treatments in Salsola komarovi Iljin between plants, and at $2^{\circ}C$ and $10^{\circ}C$ temperature treatments remained less than 1%. Oxygen contents in package both plants showed the highest level at $2^{\circ}C$ temperature treatment, but Salsola komarovi Iljin showed less oxygen contents than Suaeda maritima L. Dum. Although there was no significant difference ethylene contents in package between $2^{\circ}C$ and $10^{\circ}C$ temperature treatments, the higher showed in $10^{\circ}C$ than $2^{\circ}C$ temperature treatments. The ethylene contents in package both plants were roughly $20\;{\mu}L{\cdot}L^{-1}$ and the higher was in Suaeda maritima L. Dum than Salsola komarovi Iljin at $2^{\circ}C$. As increasing the storage temperature, the contents of carbon dioxide and ethylene in package also increased in both plants. The carbon dioxide and ethylene contents of Salsola komarovi Iljin showed a significant difference between $2^{\circ}C$ and $10^{\circ}C$ temperature treatments, but Suaeda maritima L. Dum did not show. The shelf life of Salsola komarovi Iljin based on visual quality was 14 days at $2^{\circ}C$ temperature treatment and 7.5 days at $10^{\circ}C$ temperature treatment. However, the shelf life of Suaeda maritima L. Dum did not show a significant difference between $2^{\circ}C$ temperature treatment that was 11 days, and $10^{\circ}C$ temperature treatment that was 9.5 days. Considering visual quality and gas contents in package, Suaeda maritima L. Dum might appear chilling injury at $2^{\circ}C$ temperature treatment.

Organic fertilization (OF) was an effective management strategy to improve crop yield and soil fertility. Determination of optimum application rate has been received great interest as a major research field. In this study, we evaluated optimum application level of three different organic fertilizers; mixed expeller compost (MEC), mixed organic fertilizer (MOF) and organic complex fertilizer (OCF), for garlic cultivation. Treatments consisted of MEC, MOF, OCF (50, 100, 150% of standard nitrogen input), inorganic fertilizer(NPK, N-P₂O₅-K₂O : 250-78-128 kg ha^-1) and no-fertilization (control). Overall, the yields of garlic under MEC, MOF and OCF 100% (5,337, 5,617 and 5,276 kg ha^-1) were higher than under control (4,496 kg ha^-1). The 100% of three OFs treatements showed the highest yield and bulb diameter, similar with NPK, while leaf length and bulb height were not significantly different among all treatments. The 150% of three OFs rather decreased yield. The highest nitrogen use efficiency (38.4 and 38.0%) was observed in MOF 100% and OCF100%, which was the most similar with that in NPK (38.8%). As OF application rate increased, pH was decreased, but soil NO₃-N and NH₄-N were increased. There was no significant difference in soil organic matter (OM), av. P₂O₅ and Ex. cation values. From these results, 100% application of OFs could be recommended as a suitable input level for garlic cultivation, regardless of organic fertilizer types. Further study might be required to evaluate long-term OF application effect on soil health and crop productivity.

Low phenylalanine diet(0.05%) was given to the Sprague Dawley pregnant rats at the 14 days of gestation and continued until the pups were lactated for 11 days. Body weight, plasma phenylalanine and tyrosine, brain weight, and brain phenylalanine and tyrosine were determined on pups randomly sacrificed at several intervals. Body weight of pups on normal diet (0. 36% phenylalanine) gained rapidly while the pups on the phenylalanine deficient diet decreased and did not survive during the period of 11 days. Brain weight of the pups on the phenylalanine deficient diet was significantly lower(P < 0.05) than the normal pups. Phenylalanine deficient diet did not affect the level of plasma phenylalanine of pups, but it seems that there was a positive correlation between the level of phenylalanine in the diet and the plasma tyrosine level. The plasma tyrosine level of pups on the deficient diet was decreased significantly during the Period while the pups on the normal diet increased steadily. Phenylalanine and tyrosine level in the brain was lower in Pups on the deficient diet than the pups on normal diet but the plasma phenylalanine level was not significantly different in both diets. However, plasma tyrosine level was significantly lower in the pups on the deficient diet than the normal diet at the end of the period.

Purpose: Dendropanax morifera Leveille (DML) exhibits diverse biological and pharmacological activities, including anti-oxidative effect, anti-cancer activity, hepatoprotection, immunological stimulation, and bone regeneration. As part of the identification for novel functions of DML, we investigated the therapeutic effects of DML on diabetes induced by streptozotocine (STZ) treatment. Methods: First, the four extracts including the water extract of leaf (DLW), the ethanol extract of leaf (DLE), the water extract of stem (DSW), and the ethanol extract of stem (DSE) were collected from the leaf and stem of DML using a hot water and ethanol solvent. Alterations in body weight, glucose concentration, insulin level, and pancreatic islet structure were investigated in diabetic mice after treatment with extracts of DML for 2 weeks. Results: Among four extracts, the highest level of total polyphenols and total flavonoids was detected in DLW, while the lowest level of these was measured in DSE. The radical scavenging activity was also higher in DLW than in the other three extracts at the concentration of $25-100{\mu}g/mL$, although this activity was maintained at a constant level in all groups at the concentration of $500{\mu}g/mL$. Based on the results of anti-oxidant activity, DLW and DLE were selected for examination of anti-diabetic effects in a diabetes model. Body weight was gradually decreased in all STZ treated groups compared with the No treated group. However, four STZ/DML treated groups maintained a high level of body weight during 7-14 days, while the STZ/vehicle treated group showed a gradual decrease of body weight during the same period. Also, a significant decrease or increase in the concentration of glucose and insulin in the blood of the diabetes model was detected in a subset of groups, although the highest increase was detected in the STZ/DLE-200 treated group. In addition, the histological structure of pancreatic islet was significantly recovered after treatment with DLW and DLE. Conclusion: These results suggest that DLW and DLE may contribute to attenuation of clinical symptoms of diabetes as well as prevent the destruction of pancreatic ${\beta}$-cells in STZ-induced diabetes mice.
