  • Objectives: This study examined the consumption of Han-sik and its association with the years of residence in Korea and the socioeconomic status among Filipino immigrant women of the Filipino Women's Diet and Health Study (FiLWHEL). Methods: A total of 474 Filipino women married to Korean men were included in the analysis. Their dietary intake was assessed using a single-day 24-hour recall. The participants provided information on the demographics, socioeconomic, and health-related factors through face-to-face interviews. The generalized linear model and logistic regression model were used to examine the association between the socioeconomic status and consumption of Han-sik. Results: The mean age of the participants was 34.3 years old, and the average duration of residence in Korea was 8.2 years. Among 474 Filipino women, a total of 467 consumed Han-sik, with an average of 6.8 food items per day. The Han-sik foods that the participants consumed most frequently were rice, cabbage kimchi, mixed-grain rice, and fried eggs. The average ratio of Han-sik was 58.57%. The ratio of Han-sik showed no significant associations with the years of residence, years of living together with their husband, education levels, total annual family income, or linguistic competence of Korean. However, the ratio of Han-sik use was associated with cohabitation with parents-in-law; the odds ratio (95% confidence interval) was 2.41 (1.18-4.92, p-trend = 0.002) comparing the fourth quartile with the first quartile of the Han-sik ratio. Conclusions: Filipino immigrant women in the FiLWHEL study consumed a larger number of Han-sik than Philippine foods. In addition, cohabitation with their parents-in-law was associated with the consumption of Han-sik. Further epidemiologic studies will be needed to determine how the diet affects the health and wellbeing of immigrant women in Korea.

  • Purpose: This study examined the relationship among the use of food-related content (FRC), dietary behaviors, and dietary self-efficacy to demonstrate the need for nutrition education to help adolescents build healthy eating habits and provide evidence for developing nutrition education programs for adolescents. Methods: Three hundred and eighty-one high school students in Seoul and Gyeonggi areas participated in the study. The subjects were divided into three groups (low, medium, and high) according to the level of use of the FRC, and their general characteristics, dietary behaviors, and dietary self-efficacy were analyzed. Correlation analysis was performed between FRC usage, dietary behaviors, and dietary self-efficacy, and the mediating effects of dietary self-efficacy on the relationship between the level of the use of FRC and dietary behaviors were estimated. Results: A higher level of FRC usage was associated with an increased daily cost of eating out and snacking, but no difference was observed in the BMI range. The subjects in a group with a high level of FRC usage ate convenience store or instant foods instead of homemade meals (p = 0.033), had a late-night meal or snack (p = 0.024), and turned to emotional eating under stress (p < 0.001) more than those in the low level group. In addition, the high level group checked the nutrition facts label more carefully when purchasing processed foods (p = 0.016) and exercised at least 30 minutes daily, not considering physical education classes (p = 0.057). The higher level of FRC use, the lower the dietary self-efficacy, whereby the subscales 'environmental stimulus control efficacy' and 'affective factor control efficacy' showed complete mediating effects. Conclusion: Given that FRC has been increased recently, adolescents are in need of support to help them control and enhance their dietary self-efficacy as well as develop healthy dietary behaviors through proper nutrition education programs.

  • 대황(Rhubarb)은 중국과 일본에서 혈액 순환제, 진통제, 신장치료제 등으로 전통적으로 사용되고 있는 약용식물이다. 이 연구에서는 한국산 R. undulatum L.의 뿌리 추출물, 미국산 R. rhabarbarum L.과 중국산 R. palmatum L.의 줄기 추출물의 두부 부패에 관여하는 미생물에 대한 항균 활성을 평가하였다. Rhubarb의 최적 추출을 위해서 각각 50%, 70%, 80% 에탄올을 용매로 사용하였으며, 항균 활성은 Kirby-Bauert test, minimum inhibitory concentration (MIC)과 minimum bactericide concentration (MBC)에 의해서 평가되었다. Kirby-Bauert test 결과, R. undulatum L.의 뿌리 추출물은 대부분 두부 부패균에 대해서 항균 활성을 가지는 것으로 나타났으며, R. rhabarbarum L.의 줄기 추출물의 경우는 $20{\mu}g/disc$의 농도에서는 항균 활성이 거의 나타나질 않았으나, 고농도로 갈수록 높은 항균 활성을 나타내었다. 또한 R. palmatum L.의 줄기 추출물은 고농도로 갈수록 항균 활성이 높아졌으나, Pseudomonas aeruginosa에 관해서는 항균 활성이 나타나지 않았다. MIC와 MBC에 의한 항균 활성 평가실험에서는, 세 종류의 rhubarb 추출물 중에서 phenolic 화합물이 가장 많이 함유되어 있는 R. undulatum L.의 뿌리 추출물보다 R. rhabarbarum L.의 줄기 추출물이 MIC와 MBC 값이 낮았다. 이는 phenolic 화합물의 양 이외에 낮은 pH가 항균 활성에 영향을 준 것으로 판단된다. 본 연구를 통해서 rhubarb 추출물은 두부 부패에 관여하는 미생물에 대해서 항균 활성을 가지는 것으로 나타났으며, 천연 항균제로써 식품에 적용 가능성이 있는 것으로 평가되었다. 87.1%이었으며, 아침을 매일 먹는 채식남학생은 78.8%, 비채식남학생은 33.3%, 채식여학생 47.1%, 비채식여학생 39.6%이었다. 또한 식사의 양은 과식한다는 응답이 채식남학생 24.2%, 비채식남학생 38.1%, 채식여학생은 29.4%, 비채식여학생 40.6%으로 비책식군의 과식율이 높았다. 5. 식품 섭취빈도는 두부 및 콩제품을 매일 섭취하는 경우는 채식남학생 54.6%, 비채식남학생 16.7%, 채식여학생은 38.2%, 비채식여학생이 16.8%이었다. 우유 및 유제품을 매일 섭취하는 경우는 채식남학생 6.1%, 비채식남학생 33.3%, 채식여학생 14.7%, 비채식여학생은 21.8%이었으며, 녹차, 커피 등 차를 마시지 않는다는 비율은 채식남학생 69.7%, 비채식남학생 28.6%, 채식여학생 29.4%, 비채식여학생 25.7%이었다. 인스턴트 식품을 매일 섭취한다는 응답율이 채식남학생 9.1%, 비채식남학생 21.4%, 채식여학생은 17.7%, 비채식여학생은 14.9%이었다. 6. 운동, 체중 조절 등에 대한 조사 결과 항상 운동을 하는 경우는 채식남학생 30.3%, 비채식남학생 28.6%, 채식여학생 14.7%, 비채식여학생 18.8%이었으며 운동시간은 $1{\sim}2$시간 하는 경우는 채식남학생 30.3%, 비채식남학생 38.1%, 채식여학생은 8.8%, 비채식여학생은 17.8%이었다. 체중에 만족하는 정도를 보면 채식남학생 57.6%, 비채식남학생 23.8%, 채식여학생은 23.5%, 비채식여학생은 15.8%가 만족한다고 하였다. 체중 조절 경험에서 경험이 있는 경우가 채식남학생 3.0%, 비채식남학생 31.0%, 채식여학생은 23.5%, 비채식여학생 31.7%이었다. 7. 골밀도 BQI값과와 몇가지 요인의 상관관계를 살펴보았을때, 채식남학생은 영양보충제의 섭취와 유의적인 양의 상관관계를, 해조류의 섭취정도와 유의적인 음의 상관관계를 나타내었다.

  • It has reported that a median bus-stop island on an exclusive median bus lane (EMBL) has shortened a crossing distance unit, encouraged a pedestrian's illegal crossing, and increased the number of accidents in the area. This study presents (1) the analysis of inappropriate pedestrian crossing patterns collected on exclusive median bus corridors and (2) the estimated performance of safety barriers restraining the occurrence of those. Total 19,649 pedestrian crossing data collected at the 'Sookmyung-university' median bus-stop, and the inappropriate pedestrian crossing patterns among those were grouped in terms of time and space violations. Physical safety barriers restraining illegal pedestrian crossings were considered as an alternative, and its performance in safety was quantified through microscopic simulation with conflict analyses by using surrogate safety assessment model. The findings suggest the number of conflicts reduced be 24.9 percentages compared to the one of the present condition when the physical safety barriers are placed at each of the eight ends of the EMBL pedestrian crossing.

  • Personal time perspective is a factor influencing motivation and goal-oriented behavior. The start-up process is a preparatory process for the future rather than the present. There will be a difference in entrepreneurial decision making depending on the level of time perspective. This study verified the relationship between individual 's time perspective and entrepreneurial self-efficacy. For this study, a survey was conducted with 190 students in college. To test the hypothesis, t-test, one-way analysis of variance and correlation analysis were used. The results of the study are as follows. First, we analyzed the difference of individual 's time by past-negative, past-positive, present-fatalistic, present-hedonistic, and future-oriented time. As a result of analysis, the more experience of entrepreneurship education, the higher the present-fatalistic, present-hedonistic, and future-oriented level. Second, the effect of individual's time perspective on entrepreneurial self-efficacy was analyzed. The past-negative and present-fatalistic level influenced negative on entrepreneurial self-efficacy. The present-hedonistic and future-oriented level influenced positive on entrepreneurial self-efficacy. Finally, based on the above results, academic significance, implications and limitations are suggested.

  • The purpose of this study was to examine whether single-parent family status affects children's school adjustment through children's self-care and media exposure. In addition, the study investigated the mediating effects of self-protection and media exposure of children by analyzing whether single-parent family status has effects on school adjustment through self-care and media exposure of children. For this purpose, we used data of 1,916 students in the 4th grade who participated in the 4th year of the Korean Children and Youth Panel Survey (KCYPS). The results of the structural equation modeling showed that single-parent family environment not only had direct effects on the school adjustment, but also had effects on school adjustment through self-care of children. In addition, it was revealed that self-care of children influenced school adjustment through media exposure. One of the covariates, monthly income of households, did not affect the level of children's self-care. This result draws attention to the problems of the structural deficit of single-parent families. Therefore, political measures that correspond to the structural characteristics and special needs of single-parent families, along with their current financial support, are needed to improve the level of school adjustment of children from single-parent families.
