Objective: The purpose of this study is to find out risk factors related to uterine leiomyoma in Korean women and to compare with the results of previous western studies. Methods: A retrospective analysis was carried out. All the cases of uterine leiomyoma (n=244) were diagnosed surgically or sonographically between Jannuary 1998 and December 2004. Total of 269 controls not having uterine leiomyoma were collected from patients who visited Kyungpook national university hospital for routine gynecologic check-up or treatment of their gynecologic or obstetric diseases other than uterine leiomyoma. Data were collected through review of medical records and interviews and analyzed with $x^2$ and logistic regression model. Results: In multivariate analysis, patient's age (OR 1.070; 95% CI 1.041~1.099), number of artificial abortion (OR 1.182; 95% CI 1.018~1.374) and alcohol drinking (OR 1.865; 95% CI 1.231~2.824) had significantly positive correlation with uterine leiomyoma. The duration of lactation was the only factor which had negative correlation (OR 0.985; 95% CI 0.972~0.998). BMI, parity, age at menarche, the duration and interval of menstruation, caffeine consumption and marital status did not show any correlations. Conclusion: In this study, patient's age, number of artificial abortion, and alcohol drinking were the risk factors of uterine leiomyoma in Korean women and the result was similar to that of western studies. Though we couldn't find out the specific risk factors related to the development of uterine leiomyoma in this study, but it has a great meaning to be the first trial in Korean women. The role of information bias should be carefully evaluated and further multicentered, randomized, controlled prospective studies will be needed to know the possible risk factors among Korean women.
Purpose : Recently, incidences of chronic cough with allergic disease have been increased. The identification of specific allergens for chronically coughing children is significant for diagnosis, proper treatment and prevention. The aim of this study was to identify significant contributors for sensitization in chronically coughing children. Methods : A total of 106 children, aged 1-6 years, visiting for chronic cough(>3 weeks), were tested for inhalant multiple allergosorbent assay(MAST), eosinophil count and total IgE. Parents completed a questionnaire on past history of atopy(infantile eczema) and bronchiolitis, family history of allergy, breastfeeding, smoking, pets and floor coverings at home. Results : Significant contributors for sensitization were : age(4-6 years), infantile eczema, positive family history of allergy and smoking by family. Conclusion : We were able to identify significant contributors for sensitization in chronically coughing children.
The decrease of bone mineral density gives rise to the outbreak of osteopenia and makes the possibility of a bone fracture. It makes health problems in society. It's very important to prevent osteopenia in advance. Also it's critical to prevent and take care of it in adolescent because it's the most developing period comparing to middle ages because that bone mineral density decreases. There are genetic, physical and enviromental factors that affect bone mineral density. Recently, a lifestyle and eating habits are also changing as the society atmosphere is gradually doing. This study have shown that 134 women and 75 men was chosen and responded to the survey of measuring bone mineral density and investigating a lifestyle. The measure of bone mineral density is to use Dual energy X-ray absorptiometry(DEXA) and check femoral neck and lumbar spine. Also questionaries was required to pre-made survey about their lifestyles. Analysis of data was done with SPSS program. Multiple regression analysis was used for the relation of bone mineral density, the heigths and BMI. The sample of Groups are checked for drinking, smoking or excercising about differences by t-test. The results of the experiments were; first, there is statistically significant differences in the comparisons between BMD and BMD. But there isn't any special correlation between drinking, smoking and BMD. Secondly, bone mineral density becomes low related to an intake of caffeine. Particularly, this is statically significant on women. Also there is statically significant correlation between femoral neck and quantity of motion for both men and women. Third, there is significant relation between eating habits and bone mineral density on women's lumbar spine. However, there is no significant relation between men's lumbar spine and women's one. Therefore, to prevent osteopenia, it's good to abstain from intaking caffeine within an hour after a meal. In addition, it's helpful to walk or run regularly and have a balanced meal.

In vitro antioxidant activities and neuronal cell protective effects of the ethyl acetate fraction of a new green extract (Brassica oleracea var. botytis aut italiana) against $H_2O_2$-induced oxidative stress were investigated, and its industrial feasibility was evaluated. The extract showed the highest contents of total phenolic compounds among other extracts as well as a 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenging activity and malondialdehyde (MDA) inhibitory effect. This extract not only decreased the intracellular reactive oxygen (ROS) level but also protected the neuronal cells against $H_2O_2$-induced oxidative stress. On analysis using gas chromatograph-mass spectrometry, the following phenolic compounds were identified: quinic acid, ferulic acid, and caffeic acid. Collectively, these results suggest that this new green extract could contain functional substances that would help prevent the risk of neurodegenerative disease.

To assess the physiological effects of Aruncus dioicus var. kamtschaticus extract on cytoxicity of a neuronal cell line, antioxidant activity, and neuroprotection against intensive glucose-induced oxidative stress were quantitated. Compared to the other fractions, the ethyl acetate fraction of Aruncus dioicus var. kamtschaticus (EFAD) showed the highest total phenolics and flavonoids. The 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) assay and malondialdehyde inhibitory effect test confirmed the superior antioxidant activity of EFAD. Moreover, EFAD also decreased the intracellular ROS level and suppressed neuronal cell death against intensive glucose- or $H_2O_2$-induced oxidative stress. Additionally, assessment of ${\alpha}$-glucosidase and acetylcholinesterase inhibitory activities revealed that EFAD was an effective inhibitor of ${\alpha}$-glucosidase and acetylcholinesterase. Finally, high-performance liquid chromatography analysis identified caffeic acid as the main ingredient of EFAD. Overall, these results suggest that the EFAD is a good natural source of biological compounds that counteract hyperglycemic neuronal defects.
Purpose: This study was conducted to identify differences in dietary behaviors, dietary life consumer education related situation competencies, and dietary lifestyles between baby-boom and echo generations by gender. Methods: Data were drawn from the 2016 Food Consumption Behavior Survey, and 2,474 subjects (baby-boom generation 1,304; echo generation 1,170) were selected. Results: The baby-boom generation more frequently ate meals at home with family than the echo generation, whereas the echo generation had meals more frequently at cafeterias, cafes, bakeries, convenience stores and with friends or colleagues than the baby-boom generation. However, no significant differences in dietary life related consumer education were observed between generations, and experience with food related consumer education and food related promotional/events was very low in general. Baby-boomers received their primary dietary information from surrounding people, whereas the echo generation received it from broadcasting. The information use competence was lower for the baby-boom generation (3.29) than echo generation (3.35), although this difference was not significant. Healthy dietary life competence did not differ significantly, whereas the baby-boom generation showed a higher level of practice competence than the echo generation. Additionally, the baby-boom generation was more likely to pursuit health and less likely to be concerned with convenience and taste quality than the echo generation. Conclusion: The frequencies of meal eating places, drinking, and eating-out differed significantly between the two generations, while the participation ratios of food related consumer education/events, attitudes toward education, and information use competence did not. Additionally, knowledge regarding healthy dietary life competencies did not differ, whereas practice level showed significant differences between generations. Among dietary lifestyles, the baby-boom generation showed higher pursuit of health and lower pursuit of convenience and taste quality than the echo generation.

Sensory evaluation, in vitro antioxidant activities and main compounds of coffee water-extract, coffee liqueur (CL) and coffee-ground liqueur (CGL) were investigated to consider their industrialization. Sensory evaluation showed that all groups of CGL without 25% CGL (3 month) were relatively higher than CL groups. Total phenolic compounds and in vitro antioxidant activities such as 1,1-diphenyl-2picryl-hydrazyl (DPPH) radical scavenging activity and ferric reducing/antioxidant power (FRAP) were also performed. The group of 35% CGL had higher total phenolic compounds than others, and the result of DPPH radical scavenging activity was similar to that of total phenolic compounds. In addition, 35% CGL is comparable to the FRAP of coffee water extract (CE). Qualitative and quantitative analysis using high-performance liquid chromatography (HPLC) were performed, and chlorogenic acid as a ployphenolic compound and caffeine as a nonpolyphenolic compound were detected in all samples. Moreover, the HPLC analysis showed that CGLs contain a larger amounts of chlorogenic acid (difference of 0.3~10.5%) and also greater amounts of caffeine (difference of 10.0~18.2%) more then CE. Consequently, these results suggest that coffee-ground as coffee by-products could be used as commercially available food substances because of its physiological molecules remained.
This experiment was carried out to establish effective weed control system in the cultivation of Coix lachryma-jobi L. The effect of annual weeds artificially transplanted on the growth of Coix lachryma-jobi L. were that the higher the density of weeds, the lower the yield considerably by reducing number of grains and tillers per plant. Among four weeds of Echinochloa crusgalli galli P. BEAUV., Digitaria sanguinalis $S_{COPOL}$., Chenopodium album L., and Portulaca oleracea L., weed of Portulaca oleracea L. reduced adlay yield most by 182.6kg/10a and it was judged to be the most injurious weed to adlay production. Among four weed control systems, which are one herbicide treatment, one herbicide treatment + one cultivating work with cultivator, two times cultivating work with cultivator and two times hand-weeding, the control system of 'one herbicide treatment + one cultivating work with cultivator' showed the lowest amount of weed growth by 7.34 weeds per $m^2$ in comparison with control plot of 35.00 weeds per $m^2$. Among four weed control systems, the system of 'two times hand-weeding' had much more amount of light penetration in adlay canopy with 791.9 mol than any other systems.
These studies were carried out to investigate the quality of green tea processed by different 1st-pan-firing time and to select the best conditions of green tea processing. The results were as follows. At harvesting tea plant leaf, tea plants had 4 leaves, each leaf size was $6.4cm\;{\times}\;2.4cm$, and weight of 100 buds was 40.2g. The content of moisture of green tea was decreased with the prolongation of 1st-pan-firing time, and the yield of green tea at 10 min. pan-firing time was the highest value of 20.12%. After processing green tea, 1st 10 min. pan-fired one had much more contents of total nitrogen(TN 5.41%) and total amino acid(T.A.A; 3,282mg/100g) and less content of tannin(13.22%) and caffeine(1.64%) than the other treatments. The content of chlorophyll and vitamin C went down with the extension of 1st pan-firing period. Sixteen kinds of free amino acid including theanine as a good taste component of green tea were isolated and measured by HPLC. T.A.A contents were in the range of $2,447{\sim}3,192mg/100g$ and among various pan-firing methods, 10 min. 1st pan-fired one had the highest content of T.A.A. The taste-determinants such as theanine, aspartic acid, serine, glutamic acid and arginine in green tea liquor, occupied as much as $89.4{\sim}90.0%$ of T.A.A.s. Among these, theanine was more than 50%, Lightness and yellowness of green tea were increased with delay of pan-firing time, while green color appeared to be more distinct at 10 min. 1st pan -firing time than other treatments. Besides, it gained the highest score of sensory evaluation among them. These above results suggested that 10 min. pan-fired green tea was considered to be the best level as pan-firing time of green tea processing.

The purpose of this study is to arrange for the systematic execution of safety control in children's foods through nutrition and hygiene standard suggestions and guidelines for quality certification system in children's preferable food. Aiming to achieve this objective, the study researched the present status of children’s preferable food sold near elementary schools, elicited the hazards and problems of those foods and selected nutritional and hygienic hazard components in those foods. To suggest the standards and guidelines for quality certification in children's preferable food, the study referred to sundry records, surveyed the practical cases of relevant policies and standards at home and abroad. We studied the standard of nutrition for the quality certification in those foods for sugar, fat, sodium, and additives (tar color: red No. 2 in a ban on use, caffeine), microorganism (aflatoxin $B_1$ (${\mu}g$/kg) and pathogenic bacteria (Staphylococcus aureus, Bacillus cereus, Salmonella spp.), which are the nutrients that may hamper health when taken in a large amount, and the standard for a diet restricted to under 200 kcal per one serving size. Results of distribution of processed foods (242 samples) by nutrition standards were as follows. In case of all ‘low’ level in total sugar, total fat and sodium, 0.4% of total samples was possible to be certified, In case of all ‘medium’ level in total sugar, total fat and sodium, maximumly 22.3% of total samples was possible to be certified. In case of all medium level in nutrients and $\leq$200 kcal/serving, 17.8% of total samples was possible to be certified. Certified food types was milk products and beverages.
