To develop functional bread and improve the quality of gluten-free bread, this study investigates the quality characteristics of gluten-free rice bread made from soft-type rice (Bodeurami) flour mixed with black rice at different levels (0%, 10%, 20%, 30%, and 40%, w/w). An increase in the mix level of black-rice flour increased the weight of rice bread but reduced its volume, baking loss, volume expansion, and specific volume. The results for Hunter's color value and texture measurements indicate that an increase in the content of black-rice flour reduced the L-value, the b-value, hardness, gumminess, and chewiness but increased the a-value, adhesiveness, and springiness. According to the sensory analysis, rice bread formulated with a mixture of soft-type rice flour (80%) and black-rice flour (20%) showed the highest scores in color, taste, texture, and overall preferences. With respect to flavor and appearance, bread samples with 20% and 30% black-rice flour were preferred to those with 0%, 10%, and 40% black-rice flour. These results suggest that gluten-free rice bread mixed with wet-milling rice flour and black-rice flour can be used to develop functional and gluten-free bread.

This study examines the effects of health-promoting behaviors of grandmothers participating in their infant grandchildren's nurture and provides data for enhancing the quality of their lives. The sample included 218 consenting subjects who understood the purpose of the study. These subjects resided in three cities in Jeollanam-do, Korea, and were grandmothers entrusted by their adult children with a considerable amount of nurturing for their preschool-aged grandchildren under the age of six. First, the subjects scored an average of 3.05 for health-promoting behaviors and 2.42 for entrapment. Second, the entrapment measurement based on general characteristics showed a higher level of entrapment for those with better health, a lower education level, no religion, male grandchildren to nurture, and unsatisfactory compensation. Third, health-promoting behaviors and entrapment (r=-.304) were negatively correlated. Fourth, the analysis results for effects of health-promoting behaviors of grandmothers on entrapment based on general characteristics of grandmothers as a control variable reveal a significant effect of health-promoting behaviors on entrapment. In other words, the greater the employment of health-promoting behaviors, the less likely the entrapment was to be perceived. Fifth, the results for effects of subcriteria for health-promoting behaviors on entrapment reveal a decrease in entrapment when the subjects engaged in an appropriate level of physical activity with a relaxed state of mind. These results suggest that health-promoting behaviors of grandmothers participating in their infant grandchildren's nurture are likely to influence entrapment and thus that grandmothers should make efforts to actively engage in health-promoting behaviors to reduce any maladaptive effects on nurturing. Social support and related programs should be fostered to enable grandmothers to better practice health-promoting behaviors while nurturing their grandchildren.

DOI : 10.7856/kjcls.2015.26.3.471
This study compares marital satisfaction between male and female rural migrants and explores the effects of characteristics of rural migrants and family values on marital satisfaction. Data were collected using a structured questionnaire. The survey included 483 migrants living in rural communities of North Jeolla Province and South Jeolla Province. Data were analyzed using descriptive statistics, cross tables, the t-test, correlations, and a hierarchical regression analysis using SPSS 21.0. According to the results, marital satisfaction was higher in men than in women. In addition, the effects of characteristics of rural migrants and family values on marital satisfaction were greater in men than in women. The major determinant of marital satisfaction in men was economical preparation, whereas that in women was family values. Economical preparation for rural living was more important for men, and the sufficient understanding and internalization of rural living was more important for women. In particular, family values represented the main variable between men and women in terms of marital satisfaction. These results suggest that family relationships may be the most important factor influencing rural migrants' marital satisfaction and that spousal relationships may be the core factor influencing family relationships.

This study investigates the effects of a China root (Smilax china L.) extract on the chemical and microbiological characteristics and antioxidant activity of the sausage stew sauce and the soft-tofu stew sauce over a 5-week storage period. Commercial sauces were obtained from the market, and samples were prepared using four different concentrations of the China root extract (0% (control), 0.5%, 1.0%, and 1.5%) and stored at
. Over the 5-week storage period, pH and salinity showed slight changes in both the sausage and soft-tofu stew sauces, but there was no significant difference (p<0.05) regardless of the extract amount and temperature. At 5 weeks, there were significant decreases in the total microbial count in groups with the China root extract (p<0.05) for both the sausage and soft-tofu stew sauces at
. Over the whole storage period, no coliform, yeast, and mold were detected in any sample. S. aureus counts were not detected in 1.0% and 1.5% China root groups at
, but 1.00-1.60 log CFU/g was found in the control and 0.5% groups. DPPH radical scavenging activity at 5 weeks showed an increase with an increase in the amount of the China root extract in both sauces. These results indicate that the China root extract inhibited microbial growth during storage as well as scavenging activity and thus that it can be considered to prolong the shelf life of commercial sauces.

Efforts to have children consume milk continue across the world for the sufficient supply of calcium and protein. This study examines the frequency and amount of dairy milk and the recognition, acceptability, and knowledge of milk and dairy products by considering fifth- and sixth-graders in Hwaseong, Korea. The acceptability of milk and dairy products measured based on a five-point Likert-type scale was assessed to determine its correlations with breakfast frequency, the frequency of milk intake, and milk knowledge. According to descriptive statistics, 47% and 53% of the subjects were fifth- and sixth-graders, respectively, 53% and 47% were male and female, respectively, 45.3% and 51.2% had mothers in their thirties and forties, respectively, and 57% had working mothers. Breakfast frequency was 5.2 and 5.3 times per week, and milk and dairy intake was 4.6 times. The milk knowledge score was 5.3 out of 10 points. The average daily intake of milk was a cup (55.1%), and a vast majority preferred white milk (68.6%). Ice cream bar type (4.49 points) and cone type (4.48 points) showed the highest acceptability, and breakfast frequency was positively correlated with white milk and cheddar cheese (p<0.01). Daily milk intake frequency was positively correlated with white milk and fortified milk. Milk knowledge was positively correlation with white milk, fortified milk, functional yogurt (p <0.05), fermented milk, and cheese (p<0.01). The higher the breakfast frequency, the more likely the intake of white milk (p<0.01). An increase in milk intake increased milk knowledge (p<0.05). The higher the level of knowledge, the more likely the intake of fortified milk and the frequency of milk intake. These results suggest that school lunch milk may increase awareness and milk intake through continuing education in milk knowledge. High acceptability scores for white milk, fortified milk, and fermented milk indicate their suitability for school milk consumption.

Chang, Hae-Choon ; Koh, Sang-Bum ; Lee, Jae-Joon ;
The Korean Journal of Community Living Science, volume 26, issue 3, 2015, Pages 511~522
DOI : 10.7856/kjcls.2015.26.3.511
This study investigates the acute and repeated-dose oral toxicity of crude antifungal compounds produced by Lactobacillus plantarum AF1 (Lb. plantarum AF1) and Lactobacillus plantarum HD1 (Lb. plantarum HD1) in male and female Sprague Dawley rats. In the acute toxicity study, crude antifungal compounds (500, 1,000, and 2,000 mg/kg) did not reduce mortality or produce significant changes in general behaviors or the gross appearance of external and internal organs. In the repeated-dose toxicity study, crude antifungal compounds were administered orally to rats at doses of 500, 1,000, and 2,000 mg/kg daily for 28 days. There were no test-article-related deaths, abnormal clinical signs, or body weight changes. In addition, there were no significant differences between groups treated with crude antifungal compounds and the control group in their organ weight, hematological and serum biochemical parameters, or any other factors. These results suggest that the acute or repeated-dose oral administration of crude antifungal compounds produced by Lb. plantarum AF1 plus Lb. plantarum HD1 is not toxic in male and female rats.

Kim, Kyung-Hee ; Lee, Sun-Min ;
The Korean Journal of Community Living Science, volume 26, issue 3, 2015, Pages 523~540
DOI : 10.7856/kjcls.2015.26.3.523
This study examines the structural relationships between service quality, satisfaction, and behavioral intentions in responsible tourism. In particular, the study focuses on moderating effects of age. Data were collected from 471 tourists from seven responsible tourism agencies. SPSS 20.0 and AMOS 18.0 were used for frequency, reliability, exploratory factor, confirmatory factor, and path analyses. The results of a exploratory factor analysis yield two dimensions of service quality (functional quality and technical quality). The results of structural equation modeling indicate that functional quality and technical quality had positive effects on satisfaction, which in turn had a positive effect on behavioral intentions. In addition, age moderated the relationships between service quality, satisfaction, and behavioral intentions such that functional quality had a positive effect on satisfaction in the group of tourists in their twenties and thirties and that functional quality and technical quality were important factors for tourists in their forties. The results are expected to help responsible tourism communities better manage service quality to increase tourist satisfaction.

Lee, Hwan ; Kim, Yeon-Kyoung ; Lee, Jae-Joon ;
The Korean Journal of Community Living Science, volume 26, issue 3, 2015, Pages 541~549
DOI : 10.7856/kjcls.2015.26.3.541
This study compares the major nutritional components of the leaf, flesh, and seed of dry loquat (Eriobotrya japonicaLindl.). Among proximate compositions, the crude fat, crude ash, and dietary fiber of the leaf exceeded those of the seed and flesh, whereas the carbohydrate content of the leaf was lower than that of the seed and flesh. The main component of free sugars in the leaf, flesh, and seed was fructose. Total amino acids of the leaf, flesh, and seed were 552.43, 63.00, and 260.29 mg%, respectively. Although the amino acid composition of the leaf, flesh, and seed varied, glutamic acid and
-aminobutyric acid were the major amino acids in the leaf, flesh, and seed. Major fatty acids of total lipid were oleic acid and stearic acid in the leaf and seed, and the major acid was linoleic acid in the flesh. Major organic acids were oxalic acid in the leaf, maleic acid in the flesh, and citric acid in the seed. Vitamin C content was higher in the seed than in the leaf and flesh.

Woo, Hee-Jung ;
The Korean Journal of Community Living Science, volume 26, issue 3, 2015, Pages 551~563
DOI : 10.7856/kjcls.2015.26.3.551
This study examines the mediating effects of social support on 1) the relationships between acculturative stress and depression/anxiety and 2) the relationships between emotional control and depression/anxiety in children from multicultural families. Pearson's correlations between variables were analyzed, and hierarchical regression analyses were conducted to identify direct and indirect effects of acculturative stress, emotional control, and social support on children's depression/anxiety. The sample included a total of 199 primary school students in grades 3 to 6 who lived in the Gwangju or Chonnam regions of Korea. First, there were positive correlations between acculturative stress and depression/anxiety and negative correlations between emotional control and social support. Second, social support from both peers and teachers partially mediated the relationships between acculturative stress and depression/anxiety. Third, social support from peers fully mediated the relationships between emotional control and depression/anxiety, and that from teachers partially mediated these relationships. The results suggest that social support from peers and teachers may reduce depression/anxiety in multicultural children as a mediating variable.
A Comparative Analysis of Eating Habits of Female Middle School Students in Gangwondo, Korea, According to Stress Levels
Park, Yonghyun ; Lee, Ji-yoon ; Jeong, Eun ; Kim, Bok-hee ;
The Korean Journal of Community Living Science, volume 26, issue 3, 2015, Pages 565~573
DOI : 10.7856/kjcls.2015.26.3.565
This study examines the relationships between stress and eating habits of adolescents based on the assumption that adolescents require large amounts of nutrients and that eating habits affect their physical development, academic achievement, and emotional development. For this purpose, 213 adolescents in Gangwondo, Korea, were surveyed. Many studies have reported that stress causes changes in eating habits and affects health status. Based on the dietary action guide scores according to stress categories, eating instant foods less was significant (p<0.001), eating fast foods less was significant (p<0.05), and have soft drinks less was significant (p<0.001). The results suggest the importance of balanced nutrition based on the formation of right dietary habits for adolescents. Good nutrition can be determined through right knowledge of nutrition and dietary habits, and right dietary habits can improve health and physical development as well as mental and emotional stability. The analysis did not compare other regions, and therefore any generalization of the results should be made with caution. However, the results offer important insights into stress among adolescents for their effective counseling.

Park, Ung Im ; Bae, Jeong In ; Lee, Hye Sang ; Ahn, Geun Mee ; Jeong, Woon Seon ;
The Korean Journal of Community Living Science, volume 26, issue 3, 2015, Pages 575~587
DOI : 10.7856/kjcls.2015.26.3.575
This study explores economic and psychological factors as well as dietary, clothing, and dwelling lifestyle factors that influence the happiness of college students. For this, a survey of 570 students (222 males and 348 females) was conducted using 72 categories, including general characteristics, the happiness index, the health index, and economic, psychological, dietary, clothing, and dwelling factors. Gender differences in student characteristics were analyzed through an independent samples t-test, and relationships between variables were analyzed using Pearson correlation coefficients. Variables showing significant correlations with the happiness index were classified as independent variables for the dependent variable of the happiness index and used for a regression analysis. The happiness index showed no significant gender difference, but it was higher for males than for females. Males scoring higher in the economic lifestyle and self-esteem, among others, were more likely to think practically, and their economic lifestyles were relatively rational. In both genders significant positive correlations were found between the happiness index and allowance satisfaction, the allowance level, the economic lifestyle, self-esteem, major satisfaction, and peer satisfaction. Variables more likely to influence the happiness index for males were self-esteem, peer satisfaction, the economic level, major satisfaction, and regular exercise, whereas those for females were self-esteem, peer satisfaction, and stress eating. These results indicate that emotional factors such as self-esteem and peer satisfaction were more likely to influence the happiness index of college students for both genders than economic and physical factors.
Exercise Habits and Thermoregulatory Responses of College Students
Jeong, Woon Seon ;
The Korean Journal of Community Living Science, volume 26, issue 3, 2015, Pages 589~595
DOI : 10.7856/kjcls.2015.26.3.589
This study examines how exercise habits affect human thermoregulatory responses. A total of 14 healthy male college students participated in this study as subjects: 8 students who exercised regularly (REG) and 6 students who did not (IREG). First, there were no significant differences between REG and IREG in rectal and mean skin temperatures. Second, the general thermal sensation was "slightly warm" at the equilibrium state and "cool" during body cooling in both groups with no significant differences between the two groups. This implies that exercise habits did not affect the subjective thermal sensation under this study's environmental conditions. Third, there were no significant correlations between the preferred temperature and related variables such as rectal and mean skin temperature changes, oxygen uptake, and the general thermal sensation in REG. However, there were significant correlations between the preferred temperature and the mean skin temperature change (p<0.05) and oxygen uptake(p<0.01) in IREG. In sum, these results suggest weak effects of exercise habits on daily life at the individual level. Therefore, future research should verify this study's results under controlled conditions such as cooling intensity and durations.
