The frequencies of finger print patterns and the pattern intensity index among 2, 925 Koreans (804 males, 2, 121 females) are analyzed. Total finger ridge counts was calculated for 776 Koreans (426 males and 350 females). Comparisons are made with results among other racial populations in a review of the literature. Certain differences exist between males and females in both qualitative (finger print pattern) and quantitative (total ridge count) dermatoglyphic traits. Males have higher frequences of whorls (53.6% for males, 45.7% for females), and radial loops (2.9% for males, 2.2% for females), while the frequencies of archs (1.9% for males, 2.9% for females) and ulnar loops (41.6% for males, 49.2% for females) are higher in females. The pattern intensity index for males (15.2) was higher than that for females (14.3). The mean of the total ridge count was higher (140.4$\\pm$41.2) in males than in females (129.8$\\pm$40.6). There was no correlation between total ridge count and IQ (r=-0.0027, N=343). Total ridge count among different racial groups was found to vary slightly.

The purpose of this research was to find out relationships between the use of fashion information, preference of fashion advertising and fashion leadership. This research was carried out by both the theoretical and empirical study. For the theoretical study, the research of Fashion Leadership was based on the fashion opinion leadership and innovativeness. The study include the analysis of variables influencing fashion leadership, such as use of fashion information preference of fashion advertising, and demographic variables. For the empirical study, fashion leadership was measured by fashion opinion leadership and innovativeness. The variables influencing on the fashion leadership were measured by use of fashion information (marketer-dominated information, consumer-dominated information, neutral information), preference of fashion advertising (dramatic type, feeling type, goods demonstration type), demorgraphic variables (age, years of education, family income, job, marriage). Data were obtained from 313 female in chungbuk area by self-administered questionaire. The datacollected through the questionaire were analyzed by the stastical technique - ANOVA and Duncantest, t-test, stepwise multiple-regression. The results of the study were as follows; 1. There were significant differences on the fashion leadership, fashion innovativeness, fashion opinionleadership according to the marketer dominated information and neutral information. There were significant differences on the fashion leadership, fashion innovativeness, fashion opinion leadership according to the preference of dramatic type. There were significant differences on the fashion opinion leadership according to the preference of goods demonstration type. 2. 30 percent of the total variance of fashion leadership was explained by the six variables: fashion magazines, TV & Radio advertising, clothing of TV talent & singer, years of education, dramatic type, catalogue. 3. When the subjects were divided into five groups(innovative communicators, innovators, opinion leaders, followers, indifferents) according to their innovativeness scores and opinion leadership scores, there were significant differences among groups in most of use of fashion information, preference of fashion advertising variables and in some of demographic variables. 4. There were significant interactions between marketer-dominated information and dramatic type and were significant interactions in goods demonstration type, marketer-dominated information and dramatic type. There were significant interactions between consumer-dominated information and dramatic type. This ariables has the effect on Fashion Leadership by the interactions.

The purpose of the present investigation was to determine the effect of combine exercise on C-reactive protein(CRP) and adiponectin, and to asses whether combine exercise-induced changes in insulin resistance could be explained in part by changes in these in these inflammation markers. Twenty two participants (BMI >95 percentile for age and sex) were allocated exercise group(n=12) and control group(n=10). Subjects had their body shape, body composition, glucose. insulin, HOMA-IR, CPR and adiponectin levels measured. Modest improvements in body composition, insulin resistance markers were observed, however, adiponectin and CRP did not changes. These data suggest that adiponectin and CRP is not a contributory factor to the exercise-relateted improvements in insulin resistance. Additional studies are needed to assess the effects of different duration, modes and intensities of exercise on inflammation markers.

This study aimed to produce fiber stretch sensors for smart soccer socks to prevent injuries during training. A sensor was manufactured with stretchable fabric and tested to ensure convenience during training. In order to manufacture the fiber stretch sensor, a CNT dispersion solution was applied to an e-band and elastic polyester fabric, and the performance of the sensors was evaluated by a tensile test. Performance evaluation showed that both of the tested fabrics are excellent for this purpose. Both sensors were attached to socks to create prototype wearable devices, and an experiment was conducted to determine whether a resistance change accompanying relaxation and contraction of the gastrocnemius muscle could be detected. In order to accurately evaluate performance as a sensor, the fabric was stretched 20 times at low speeds of 1 Hz and 0.5 Hz. A change in resistance due to tension was observed, with both the E-band and the stretchable poly fabric showing high sensitivity and high reproducibility. Both can be used as relaxation/contraction sensors. Smart soccer socks were made using the two materials, and an evaluation was conducted. Tensile tests were done on the smart soccer socks; the tests were done 20 times per sock, and the sensor showed a stable resistance change between 30 and 40 ohms depending on the tension of the sensor. As a result, we confirmed that smart soccer socks with stretch sensors made of E-bands can measure changes in the gastrocnemius muscle.

This study examined the effects of negative parenting attitudes on adolescents' academic helplessness through the mediating effects of social withdrawal and smartphone dependency. Data from the panel study of Korean Children and Youth Panel Survey 2018 (KCYPS 2018) collected by the National Youth Policy Institute (NYPI) was used to examine the research model. The subjects of the study consisted of 2,541 first grade middle school students (1,375 boys and 1,166 girls). Confirmatory factor analysis [CFA], structural equation modeling [SEM], and bootstrapping analysis were conducted by means of SPSS 25.0, AMOS 25.0, and Hayes's PROCESS programs to examine the serial multiple mediating effects. The study results were as follows. First, negative parenting attitude had a direct effect on adolescents' academic helplessness. This implies that adolescents who perceive their parents' attitudes to be high in coercive, rejective, and chaotic levels indicate that they can easily get exhausted in academic settings. Second, negative parenting attitudes had an indirect effect on adolescents' academic helplessness through social withdrawal and smartphone dependency. The results suggest that a high level of negative parenting attitude leads to higher social withdrawal and smartphone dependency that influences adolescents' academic helplessness.

This study investigated the dyeing properties and bio-functions of cotton fabrics dyed with naturally fermented Ecklonia cava extract in order to compare it with a comparison of unfermented extract. Hot water-extracted Ecklonia cava was fermented naturally under the various conditions of a fermenting period (2-8 days) and amount of molasses (0.1-1.8% v/v); in addition, it was also tested for characterization by FT-IR, antioxidant activity, total polyphenol content, and anti-microbial activity. For dyed cotton fabrics, color strength (K/S), physical color properties, dyeing fastness, sun protective property, and anti-microbial activity were evaluated considering dyeing conditions. As a result, the fermented dye under fermentation condition of 0.1% v/v with molasses during 4 days was revealed as having a similar chemical structure to the unfermented one and showed a total polyphenol content with 32.88mg/g and better antioxidant activity than the unfermented one. As for dyed fabrics, the color strength value by K/S was the highest under the condition of 0.1% v/v of molasses during 4 days among all fermenting conditions. The dyed fabrics had a reasonably good fastness (except for light). Anti-microbial activity against K. pneumoniae was better for the fermented extract-dyed fabric especially with lower dye concentrations.

This study examined the effects of perceived discrimination on multicultural adolescents regarding feelings of conflict over their ethnic identity by investigating the moderating role of father-child open communication and mother-child open communication mediated by bicultural competence. A total of 234 middle school students (grades 7-8; 139 girls and 95 boys) from multicultural families, from which the father is Korean and the mother is not, participated in the study. Data was collected through an online self-report questionnaire and was analyzed via SPSS 26.0 and Process (Version 4.1) MACRO. The results can be summarized as follows. First, bicultural competence mediated the effects of perceived discrimination on feelings of conflict over one's ethnic identity. Enhanced bicultural competence resulting from a lower perception of discrimination contributed to a reduction in feelings of conflict over one's ethnic identity. Second, the moderated mediation effect of fatherchild open communication was significant, while the effect of mother-child open communication was not. Thus, the mediation relationship (lower perceived discrimination increased bicultural competence and, thus, reduced conflict over one's ethnic identity) grew stronger as the level of father-child open communication increased. The significance of this study lies in uncovering the causal relationships between individual and environmental factors that contribute to ethnic identity development among multicultural adolescents, particularly highlighting the important role of Korean fathers within multicultural households.

This study was conducted to investigate variables related to dietary fiber intake among sixth grade children in an elementary school in Daejon city. One hundred and forty-seven children completed a questionnaire for determining their socioeconomic background and their food habits. Anthropometric measurements were taken, and a 24-hour diet recall method was used to collect three-day food intakes. The socioeconomic status of the children's families belonged to the upper middle class; 53.0% of their fathers and 25.8% of their mothers had completed college or higher degrees. 27.9% of the mothers had jobs, including part-time jobs. Approximately 30% of the children skipped breakfast, 66.4% of the children preferred animal foods to plant foods, and 52.4% of the children preferred green vegetables to yellow or pale vegetables. Grilled meat dishes, such as Grilled beef rib with seasoning, Bulgogi, grilled pork belly and beef steaks, were the most popular types of food eaten outside home by the children. Daily dietary fiber intake was 14.5 g in boys and 14.5 g in girls, and these intakes are low compared to the standard guidelines. The average intakes of energy and protein of the children were 84.5% and 114.0% of the Korean Recommended Dietary Allowances (RDAs), respectively. Besides energy, riboflavin, iron and calcium intakes were below the RDAs, and especially calcium intake was only 50% of the RDAs. On the other hand, thiamin, niacin, ascorbic acid, protein and phosphorus intakes exceeded the Korean RDAs. Family income or the children's body mass index (BMI) was not directly related to dietary fiber intakes. However, higher dietary fiber intakes tended to be related to higher intakes of green vegetables and fruits. Children with higher dietary fiber intake tended to prefer plant foods to animal foods. Energy and most nutrients, except heme iron and retinol, showed positive relationships with dietary fiber intake. Especially potassium and plant origin protein and calcium were highly correlated with dietary fiber intakes(r＞0.6). From these results, it is concluded that dietary fiber intakes of these sixth grade elementary school children were less than the standard reference and it is anticipated to decrease further in the future with increased incomes. Therefore, increased intakes of dietary fiber by elementary school children should be promoted through nutrition education, together with the development of cooking methods and recipes utilizing green vegetables and fruits.

Purpose : Obesity and iron deficiency are common nutritional problems. Obese children are known to have iron deficiencies, but one presented opposite opinion in Korea. This study investigated the prevalence of obesity and iron deficiency in Incheon and the relationship between iron deficiency and obesity. Methods : Physical measurement and hematologic examinations were done a 764 healthy female students aged 14 to 15 years in May, 2005. Overweight was defined as a body mass index ${\geq}85th$ percentile. Iron deficiency was defined as serum ferritin <10 ng/mL. Iron deficiency anemia (IDA) was defined as serum Hb <12 g/dL and serum ferritin <10 ng/mL and/or transferrin saturation <16%. Results : 1) The prevalence of overweight was 24.4 percent (n=186), and that of obesity 16.5 percent (n=126). Ferritin and transferrin saturation was the lowest in the normal weight group. 2) The prevalence of iron deficiency and IDA was 18.7 percent (n=102) and 5.3 percent (n=41), respectively. 3) Iron deficiency was more common in the normal weight group compared with the overweight and underweight groups. Also, the non-obese had more iron deficiency and IDA than the obese. Conclusion : The prevalence of obesity in middle school girls could be higher in Incheon than in other regions, but there might be no difference in iron deficiency. However, iron deficiency was more prevalent in the normal weight group than in overweight group. The overweight group ate more food and gained more iron, so seemed to be less prevalent in iron deficiency than the normal weight group.
