Effects of Multicultural Acceptance Attitude, Language Acceptance Attitude and Social Network on Married Female Immigrants and Korean Husbands' Life Satisfaction during the Adjustment Period
Jung, Joowon ; Cho, So Yeon ;
The Korean Journal of Community Living Science, volume 27, issue 2, 2016, Pages 185~197
DOI : 10.7856/kjcls.2016.27.2.185
This study was conducted to examine the factors affecting the life satisfaction of married female immigrants and Korean husbands. Data for this study were obtained from the National Survey of Multicultural Families conducted in 2012. The study sample consisted of 5,232 couples within the first five years of marriage. Data were evaluated using a paired t-test, K-mean cluster analysis, ANOVA, and ordered logistic regression analysis. The results were as follows: 1) life satisfaction was higher for married female immigrants than for Korean husbands. 2) The general characteristics, acceptance attitude, language acceptance, and social network differed significantly depending on life satisfaction levels. 3) The multicultural acceptance attitude of husbands, ability of married female immigrants to speak Korean, and ability of Korean husbands to speak wives' native languages improved life satisfaction levels. The results of this study can be used to improve the life satisfaction of married female immigrants and Korean husbands.
The Mediating Effect of Emotional Intelligence on the Relationship between Mothers' Attachments to Young Children and the Creative Personality of the Children
Nam, Yun-Ju ;
The Korean Journal of Community Living Science, volume 27, issue 2, 2016, Pages 199~209
DOI : 10.7856/kjcls.2016.27.2.199
This study examined the mediating effects of emotional intelligence on the relationship between mothers' attachments to young children and the creative personality of the children. Pearson's correlations between variables were analyzed, and hierarchical regression analyses were conducted to identify the direct and indirect effects of a mothers' attachments to young children and the emotional intelligence and creative personality of the children. The sample included a total of 228 children aged 4-5 who were attending nursery in Gwangju, Korea. Significant differences were observed by gender and age, but no significant differences were found to be associated with the mother's attachment to the child by age. However, emotional intelligence partially mediated the relationships between the mother's attachment to the child and the child's creative personality. The results suggest that emotional intelligence may edify the creative personality of young child as a mediating response to the mother's attachment.

The current study was carried out to determine the effects of the seed, flesh (seedless fruit), and leaf of loquat (Eriobotrya japonica Lindle.) on antioxidative activity and anti-proliferation in human cancer cells. Total polyphenol contents of loquat seed, flesh, and leaf ethanol extracts were found to be 17.77, 32.32, and 28.08 mg/g, respectively. Also, total flavonoid contents of loquat seed, flesh, and leaf ethanol extracts were found to be 18.77, 28.73, and 21.35 mg/g, respectively. The
values of DPPH hydroxyl scavenging of loquat seed, flesh, and leaf ethanol extracts were 0.049, 0.063, and 0.042 mg/mL, respectively. Antioxidative indexes of loquat leaf and seed ethanol extracts was highly and it was similar to the BHA and BHT. The antioxidative activities in loquat seed and leaf ethanol extracts were higher in loquat flesh. The antiproliferation effect of loquat seed and leaf ethanol extracts on liver cancer cell line (H460), stomach cancer cell line (AGS) and lung cancer cell line (A549) showed higher values compared with the flesh ethanol extracts. These results indicate that loquat ethanol extracts may play a positive role in antioxidative properties and cancer prevention.
Effects of Participation in Adult Education on Cognitive Function: The Mediating Effect of Relationship with Children among Older Adults
Lee, Sungeun ;
The Korean Journal of Community Living Science, volume 27, issue 2, 2016, Pages 221~231
DOI : 10.7856/kjcls.2016.27.2.221
This study was conducted to investigate the effects of participation in adult education on cognitive function, and the mediating effects of relationships with children among older adults. This study employed data from the 2011 Elderly Survey, and a total of 8,668 older adults over 65-years old were used for analysis. Multiple linear regression analyses were used to examine the mediating effect of relationship with children based on the approach proposed by Baron & Kenny (1986). The results showed that participation in adult education increased cognitive function of older adults. Adult education participation also increased satisfaction with relationship with children, and relationship with children was found to have a mediating effect. These findings suggest that there is a need to recognize the importance of the relationship between older adults and children when developing education programs for older adults.

Won, Hyang Rye ;
The Korean Journal of Community Living Science, volume 27, issue 2, 2016, Pages 233~243
DOI : 10.7856/kjcls.2016.27.2.233
This study examined the antioxidant activity and lipid composition of rats fed a high fat-high cholesterol diet containing Salvia plebeia water extract. Three levels (50 mg/kg, 200 mg/kg, 500 mg/kg) of Salvia plebeia water extract were administered to seven weeks old male Sprague Dawley rats for four weeks. The activity of glutathione peroxidase in serum was high in all groups that received the Salvia plebeia water extract (p<0.05). The glutathione reductase activity was high (p<0.05) in groups that received 50 mg/kg and 500 mg/kg of Salvia plebeia water extract. When rats received Salvia plebeia water extract, the content of MDA (malondialdehyde) in the serum and liver was low in all groups. In addition, the serum total lipid, triglyceride, total cholesterol and LDL-cholesterol contents decreased significantly (p<0.05). Total cholesterol and triglyceride levels in the liver were significantly lower in the group that received the Salvia plebeia water extract than in the control group (p<0.05). Salvia plebeia water extract improves lipid metabolism and it almost meets with the increase of antioxidant activity and peroxide formation reduction. Based on these results, supplemented of a high fat-hypercholesterol diet with Salvia plebeia can increase antioxidant activity and depress peroxide formation in serum, as well as liver cholesterol and triglycerides.

DOI : 10.7856/kjcls.2016.27.2.245
This study was conducted to investigate the thermoregulatory behavior of young males in terms of self-identified thermal tolerance. We recruited 436 male students from Seoul (
in body mass, and
in BMI) in accordance with four types of self-identified thermal tolerance: 1) tolerable of both cold and heat, BCH (N=15); 2) heat tolerable only, HTO (N=118); 3) cold tolerable only, CTO (N=162); and 4) neither cold nor heat tolerable, NCH (N=141). The questionnaire consisted of 55 questions regarding preference to cold or heat environment, seasonal thermoregulatory behaviors including clothing habits, seasonal sleeping environments, health care/physical fitness, and anthropometric items. The results showed that: 1) BCH preferred less auxiliary heating devices, gloves/hats, or thermal underwear in winter and had very few experiences with cold/heat injuries or catching a cold, whereas NCH showed the opposite behavior and experiences as BCH; 2) thermoregulatory behaviors were not symmetrical between summer and winter. Most male students preferred cold beverage/foods to using cooling devices to lower body temperature in summer, whereas auxiliary heating devices were preferred to warm beverage/foods to maintain body temperature in winter; 3) thermoregulatory behaviors of NCH had more items in common with HTO than CTO, while the behaviors of BCH were more closely related to CTO than the behaviors of BCH were more closely related to CTO than HTO. Overall, we confirmed that thermoregulatory behaviors were apparently classified by self-identified thermal tolerance, and such behaviors could be adjusted by improving cold or heat tolerance.

Jang, Young Ae ; Kim, Sang Lim ;
The Korean Journal of Community Living Science, volume 27, issue 2, 2016, Pages 265~280
DOI : 10.7856/kjcls.2016.27.2.265
The study examined the effects of fathers' parenting involvement and parenting behaviors on child happiness. A total of 270 elementary school students in 4th, 5th, and 6th grades (139 boys and 131 girls) participated in the study and completed the questionnaires. The collected data were analyzed using descriptive statistics, analyses of variances, correlation coefficients, and multiple regression. Fathers' parenting involvement and parenting behaviors did not differ by gender and grades, but child happiness partially differed in response to those factors. Additionally, child happiness was significantly positively correlated with fathers' parenting involvement and parenting behaviors. Moreover, fathers involvement in leisure activities, daily-life guidance, and study guidance, as well as their being warm receptive and rejective restrictive parenting behaviors were found to be significant variables influencing child happiness. Overall, the results of this study suggest fathers' play important roles in child happiness and that development of an education program for fathers is warranted.
A Study on the Optimal Energy Mix Model in Buildings with OEMGD Algorithm Focusing on Ground Source Heat Pump and District Heating & Cooling System
Lee, Key Chang ; Hong, Jun Hee ; Lee, Kyu Keon ;
The Korean Journal of Community Living Science, volume 27, issue 2, 2016, Pages 281~294
DOI : 10.7856/kjcls.2016.27.2.281
This study was conducted to promote consumer interest in Geothermal Heat Pump (Ground Source Heat Pump, GSHP) and district heating and cooling (District Heating & Cooling, DHC) systems, which are competing with each other in the heating and cooling field. Considering not only the required cost data of energy itself, but also external influence factors, the optimal mix ratio of these two energy systems was studied as follows. The quantitative data of the two energy systems was entered into a database and the non-quantitative factors of external influence were applied in the form of coefficients. Considering both of these factors, the optimal mix ratio of GSHP and DHC systems and minimum Life Cycle Cost (LCC) were obtained using an algorithm model design. The Optimal Energy Mix of GSHP & DHC (OEMGD) algorithm was developed using a software program (Octave 4.0). The numerical result was able to reflect the variety of external influence factors through the OEMGD algorithm. The OEMGD model found that the DHC system is more economical than the GSHP system and was able to represent the optimal energy mix ratio and LCC of mixed energy systems according to changes in the external influences. The OEMGD algorithm could be of help to improve the consumers' experience and rationalize their energy usage.
The Evaluation of Water Vapor Transport and Waterproofness Properties of the Waterproof and Breathable Fabrics
Shim, Huen Sup ;
The Korean Journal of Community Living Science, volume 27, issue 2, 2016, Pages 295~304
DOI : 10.7856/kjcls.2016.27.2.295
This study was conducted to evaluate and compare the waterproofness and water vapor transport properties of 30 waterproof and breathable textiles in the market. MVTR upright cup test with water, MVTR inverted cup test with potassium acetate, and sweating hot plate test method were used for measuring the breathability of fabric samples. The waterproofness of all fabric samples and evaporative resistance of garment ensembles made with 5 selected waterproof and breathable textiles out of 30 samples were tested. The results of this study were as follows. The base fabrics of the most samples were basic weave structure with either polyester or nylon fiber. The waterproofness was over
for all the samples except densely woven fabrics. The evaporative resistance of garments that were made out of 5 fabric samples with a range of low to high breathability ranged
. The data of the water vapor transport properties of fabric samples varied with different test methods. Overall the bicomponent film fabrics showed better breathability and less standard deviation regardless of test methods. It is expected the breathability data without the information of test conditions used for marketing would confuse the consumers and the apparel manufacturers.

The Korean Journal of Community Living Science, volume 27, issue 2, 2016, Pages 305~318
DOI : 10.7856/kjcls.2016.27.2.305
This study was conducted to investigate the effects of service quality and food quality on purchase intention in the electronic commerce of food products. Specifically, the relationship between purchase intention and food quality and service quality was tested based on customer satisfaction and trust, which were measured using the structural equation modeling method. Quality of service was found to affect purchase intention; however, food quality had no positive effects on purchase. Additional analyses should be conducted owing to the conflicting results of the present study. Although the amount of food bought online is increasing rapidly every year, research regarding online food purchasing is not being actively conducted. The results of the present study will help food sellers, buyers, and researchers.
