Caffeine is an alkaloid of the methylxanthine family known as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness in humans. There is a recommended upper limits of caffeine for health because a high dose can cause negative effects. Chlorogenic acid is a natural polyphenol compound known to have an antioxidant activity. In this study, the contents of caffeine and chlorogenic acid in coffee beans from different origins(Costa Rica, Indonesia, Vietnam) were determined by using liquid chromatography-tandem mass spectrometry(LC-MS/MS). The experiment offers more selectivity and sensitivity for those compounds compared with conventional methods such as UV/VIS spectrophotometry. The average concentrations of caffeine and chlorogenic acid in coffee beans origined in Costa Rica were 15.05 mg/g and 5.33 mg/g respectively. In the case of coffee beans origined in Indonesia, the average concentrations were 13.10 mg/g for caffeine and 3.75 mg/g for chlorogenic acid. Vietnamese coffee showed that the average concentrations were 17.79 mg/g for caffeine and 1.12 mg/g for chlorogenic acid. This study can contribute to a better understanding of the contents of caffeine and chlorogenic acid in various coffee beans in order to evaluate dietary intake.

The purpose of this study was to examine the effect of the children`s school adjustment on family strength, social support and parental efficacy according to their parents perception and to submit basic material to recognize the necessity of strengthening parental capability for enhancing children`s adaptation to school. The summary of the results of the study was as below. All of the subjects who recognized family strength, social support and parental efficacy according to their parents perception showed middle score over 3. The parents who recognized family strength and parental efficacy were examined as the factors which influence children`s adjustment to school. These showed that children`s adjustment to school is better when parents recognized that family strength is higher, and when parents recognized that parental efficacy is higher. But when parents recognized social support, no meaningful influence appeared, so if the parents who are first social supporters of school-aged children understand the importance of children`s adjustment to school, which has a high adaptability with high social support, and recognize the difference of the influence of social support on the children`s adjustment to school and home, it could be the factor to reduce children`s adjustment problems at school.

Choi, Moo Young ; Rhim, Tae Jin ;
The Korean Journal of Community Living Science, volume 24, issue 1, 2013, Pages 27~36
DOI : 10.7856/kjcls.2013.24.1.27
This study was performed to investigate the antimicrobial effect against food-borne pathogens of Sanguisorbae officinalis L. ethanol extract. The antimicrobial activity of the ethanol extract was determined using a paper disc-diffusion method and the diameter of the clear zone was measured. The diameters of the clear zone in the presence of 10 mg of the ethanol extract were the maximum against Staphylococcus aureus among the tested 4 gram-positive bacteria and Pseudomonas aeruginosa among the tested 7 gram-negative bacteria. Analysis of the minimum inhibition concentrations (MIC) showed that the ethanol extract exhibited a similar efficacy as sorbic acid, well-known chemical preservatives. The growth inhibitory effects of the ethanol extract in the concentrations of 250, 500, 1,000 and 2,000 mg/L on food-borne pathogens were determined against Staphylococcus aureus, Bacillus subtilis, Salmonella Typhimurium and Pseudomonas aeruginosa. The growth of the microorganisms was significantly (p<0.05) inhibited by the ethanol extract in the concentrations higher than 250 mg/L. Thus, the results of the present study demonstrate that the ethanol extract exhibits antimicrobial effects against food-borne pathogens, suggesting that Sanguisorbae officinalis L. could be used as natural antibacterial agent in food.

Lee, Mee Ae ; Kim, Dae Chul ;
The Korean Journal of Community Living Science, volume 24, issue 1, 2013, Pages 37~49
DOI : 10.7856/kjcls.2013.24.1.37
The purpose of this study is to explore how health and health behavior factors moderate the relation between socio-economic position(SEP) and Korean elderly people`s self-rated health status. The data sources are from the Korean Longitudinal Study of Aging(2008). The analysis sample consists of 4,040 cases. Analysis of the results shows that health characteristics such as ADL, MMSE, geriatric depression, and pain are significant predictors of self-rated health status. In addition, exercise and drinking alcohol also prove to be factors influencing self-rated health status. Health factor such as MMSE and health behavior factors such as drinking alcohol served as moderators of the influences of SEP on one`s self-rated health status. For example, higher MMSE provides a slight increase to the positive relationship between SEP and self-rated health status. In addition, those who responded yes to drinking alcohol, compared to those who responded no, provides an increase to the positive relationship between SEP and one`s self-rated health status.

Kim, Jikyung ; Kim, Gyunhee ;
The Korean Journal of Community Living Science, volume 24, issue 1, 2013, Pages 51~70
DOI : 10.7856/kjcls.2013.24.1.51
The purpose of the study was to analyze the determinants on the absence of after-school care among elementary students. This study is based on the National Children and Youth Panel Survey(2010) data and analyzed through Binary Logit Model and Multinominal Logit Model. The Following results were obtained: First, school grades, the number of siblings, mother`s education, family type by parental employment, family structure, family type by parental nativity, and family income, all affected the absence of after-school care. Second, the absence days of after-school care was affected by different factors. 1day-2days a week in absence of after-school was more likely to increase among children with more siblings and an older father. On the other hand, spending over 3-4days a week without after-school care was more likely to increase among mothers with lower education, dual-earner families, multicultural families, lower family incomes, small cities and rural areas. Based on the results of this study, we agree with the generalization and the diversification of after-school care policy for elementary school students.
The Influence of Social Participation on School Adjustment in Early Adolescents: Mediating Effects of a Sense of Community
Kim, Myoung Il ; Ko, Ah Ra ; Lim, Kyung Mi ;
The Korean Journal of Community Living Science, volume 24, issue 1, 2013, Pages 71~84
DOI : 10.7856/kjcls.2013.24.1.71
In this study we examine the relationship between the social participation in the early adolescents and school adjustment as well as the mediating effects of a sense of community. Findings provide ways of intervention that can increase a youth`s school life. Based on samples of 2,351 first grade middle school students from the data in the `Korea Youth Panel Survey` administered by the National Youth Policy Institute, we analysed the correlation among the variables. The results are as follows. First, the social participation of youths showed a major influence on school adjustment, and was identified as: the more the students participate in social activities, the better the students get adjusted to school. Second, the social participation has a significant effect on sense of community. In other words, the more the students participate in social activities, the more the students get a sense of community. Third, a sense of community mediated the process of social participation on school adjustment. These findings indicate that in order to increase a youth`s school adjustment, a promotion of social participation and an effort to increase a sense of community are required. The implications of these findings suggest that by intervening social welfare and policy, can improve the integrity of a youth`s school life.

The purpose of this study was to develop an appropriate jacket pattern for obese women in 20s and 30s, providing a good fit and appearance. The results were as follows: among 3 kinds of patterns collected in order to develop a jacket pattern to fit the average body of an obese woman in 20s and 30s, a business-type pattern(which was comparatively evaluated as a good fit) was worn and revised so as to design a final research pattern with proper fitness and a good shape. The biggest problem of the existing pattern was may overall spares, especially many spares of bust size, waist measurement, hip circumference, all of which makes a bad appearance. Considering the results of a survey which indicates that young obese women like tight-fitting clothes, bust size was decreased from 8 cm to 6 cm, and their waist measurements were bigger compared to other age groups, so a total of 1.1 cm(with 0.3 cm in the front, back side, and 0.5 cm in the back waist) was decreased. The hip circumference was decreased by 2 cm from H/2+4 to H/2+2 cm, the quantity of front deflection was established as 1.5 cm in order to compensate for the coming off of the front side caused by the fat on the stomach.

Jin, Yan Chun ; Jang, Young Ae ;
The Korean Journal of Community Living Science, volume 24, issue 1, 2013, Pages 99~118
DOI : 10.7856/kjcls.2013.24.1.99
The purpose of this study was to examine the effects of parenting efficacy, parenting behavior, and parenting stress on children`s problematic behavior in Korea and China. The subjects were 292 children and their mothers who are caring for their 3-5 years old children in Korea and China. Data was collected using a parenting efficacy index, parenting behavior index, parenting stress index and child behavior check list. The data were statistically analyzed using t-test, one-way ANOVA (Scheff
test), correlation analysis and multiple regression analysis. The study showed that there were no significant differences in parenting efficacy, parenting behavior, parenting stress and children`s problematic behavior in Korea and China. There were some significant differences in children`s problematic behavior according to the socio-demographic variables, that is the gender of the child, the mother`s education, the father`s education, in Korea and China. Correlation analysis indicated that the parenting efficacy, parenting behavior, parenting stress and children`s problematic behavior in Korea and China had significant correlations in some sub-variables. It was also found that the gender of the child, the mother`s education, the father`s education, the frustration and uneasiness of the parents, the control behavior, and the stress of parent-child dysfunctional interaction, were all significant predictors of the preschool children`s problematic behavior in Korea, and the mother`s education, the family income, the affection behavior, the rejection behavior, and the control behavior, were all significant predictors of the preschool children`s problematic behavior in China.
Influences of Work Characteristics on Older Workers` Job Satisfaction: Focusing on Gender Differences
Jung, Yunkyung ;
The Korean Journal of Community Living Science, volume 24, issue 1, 2013, Pages 119~132
DOI : 10.7856/kjcls.2013.24.1.119
This study aims to understand potential gender differences in the association between job characteristics and job satisfaction among older workers. The data are from 506 males and 202 females older than 55 from the first wave of the Korean Longitudinal Study of Ageing(KLoSA). Analyses focused on examining gender differences in the influences of subjective evaluation of work characteristics measured with education and skill fits of the work, work demands, customary early retirement, as well as more objective job conditions assessed with insurances by the employer, work hours, and salary on job satisfaction. Regression analyses revealed that female workers showed higher job satisfaction while job characteristics worked differently between genders to affect job satisfaction. For males, fitting the job with education and job demands were determining factors of job satisfaction, while the job with skills and work hours appeared to be significant factors for females. Results suggest that opportunities to utilize older workers` human capital and flexible working hours, especially for females workers would be helpful in promoting older adults` employment and satisfaction about their work.

This study was conducted to assess the dietary intake of college students in Gyeonggi-do. The dietary survey data were obtained by a semi-quantitative food frequency questionnaire given to 103 students, 56 males and 47 females. The average age the of subjects was 22.5 years old for the male students and 20.9 years old for the female students. Among the subjects, 38 males and 26 females` height, weight and percentage of body fat were measured using Inbody 3.0. The average height, weight, Body Mass Index(BMI) and percentage of body fat of the subjects was 173.1cm, 68.6 kg, 22.9 and 18.9% for males and 162.5 cm, 54.1 kg, 20.5 and 28.1% for females, respectively. The mean daily intake of energy was 2,343.0 kcal for males and 2,062.0 kcal for females. The average intake of protein, carbohydrates, Vitamin B1 in the male students were significantly higher than those of the female students(p<0.05). The average of Nutrient Adequacy Ratio(NAR) was ranged from 0.60(folate) to 0.99(phosphorus). NAR of Vitamin A and calcium was 0.71 and 0.75, respectively. The average of Mean Adequacy Ratio(MAR) was 0.85. The intake of rice and oriental cereals(sum of the parched cereal powder, ramen, noodles, Chajangmyon, buckwheat vermicelli, buckwheat noodles, dumplings and rice cakes) in the males was significantly higher than those of the females. The intake of snacks in the females was significantly higher than that of the males. Appropriate nutritional education for an optimal intake of nutrients may help to improve the quality of diet in college students.

The objective of this study is to find the effect of improving hyperlipidemia through Platycodi radix saponin. A hypercholoesterol diet and Platycodi radix saponin methanol extract were supplemented to the 6 week old male Spargue Dawley rats for four weeks. Results showed that the serum total cholesterol, triglyceride and LDL-cholesterol level decreased in the group supplemented with Platycodi radix saponin methanol extract(p<0.05), however, the serum total lipid and HDL-cholesterol did not show any difference from the control group according to the supplement of Platycodi radix saponin methanol extract. In the group supplemented with Platycodi radix saponin methanol extract, the total cholesterol decreased by 20%, triglyceride by 36% and LDL-cholesterol by 25% respectively, and there was no difference according to the level of Platycodi radix saponin methanol extract. AI(atherogenic index) and CRF(cardiac risk factor) were low in the group supplemented with Platycodi radix saponin methanol extract. Total lipid, total cholesterol and triglyceride in liver and feces were significantly low in the group supplemented with the Platycodi radix saponin methanol extract compared with the control group(p<0.05). According to this result, it is expected that the Platycodi radix saponin methanol extract supplemented in the hypercholesterol diet can lower atherosclerosis, the cause of cardiovascular disease, by reducing not only serum cholesterol and triglyceride but also liver cholesterol and triglyceride.
