  • The purpose of this study was to estimate the iron availability and to analyze dietary factors which influence hematological indices of 130 female adolescents with iron deficiency anemia. Intakes of iron and other nutrients were estimated using a self-administrated questionnaire combined with the 24-hour recall mehtod and iron availability was calculated by Monsen's method. Mean daily intakes of calorie, protein and vitamin C were 1631.0kcal(77.7% of RDA), 54.7g(84.2% of RDA) and 45.7mg(83.0% of RDA), respectively. In terms of iron, mean daily intake was 8.7mg(48.3% of RDA) and heme iron intake was 3.0mg which correspond to 34% of total iron intake. The amount of total absorbable iron was 1.5mg and the estimated bioavailability of dietary iron was 17.2%. In summary, intake of several nutrients for most of the subjects were under RDA. Dietary factors affecting hematological indices were analyzed by stepwise multiple regression. Intake of vitamin C was a major determinant of Hb level, while both intake of enhancing factor and iron availability were major determinants of serum ferritin level. In conclusion proper nutritional education and guidance for iron deficiency anemic female adoalescent needs to be developed and to improve their iron storage should be increased intakes of enhancing factors, female adoalescents.

  • Purpose: This study was examined the quality of the sexual life among married women in terms of the factor structure of Sexual Quality of Life(SQOL) and evaluated the predictive value of 11 variables for SQOL. Method: Two hundred and ninety-three married women completed the Korean version SQOL scale with information on age, education, length of marriage, family income, health, sexual knowledge, coital frequency, harmony with family members, levels of affection, and general and sexual communication. Data were analysed with principal components and regression analyses. Result: The SQOL scale had two clearly defined factors, Negative Quality of Sexual Life and Positive Quality of Sexual Life, on which all scale items were significantly loaded, accounting for 54.3% of the total variance. Independent regression analysis showed all variables except education to be significant predictors of SQOL with interpersonal variables (general and sexual communication, affection and harmony with family members) being the most powerful predictors. However when the 11 variables were combined together in stepwise analysis, only 6 variables (general communication, age, affection, coital frequency, sexual knowledge and health) were significant, accounting for 39% of the total variance. Conclusion: The Korean version SQOL scale is a good measure to tackle SQOL in married women. To enhance SQOL, strengthening interpersonal interaction focusing on general/sexual communication, affection and harmony with family members seems to be more important than sexual activities and personal characteristics.

  • C3HC4-type RING zinc finger proteins essential in the regulation of plant processes, including responses to abiotic stresses. We previously isolated and examined the C3HC4-type RING zinc finger protein (BrRZFP1) from Brassica rapa under abiotic stresses. To elucidate the role of the BrRZFP1 transcription factor in gene regulation, we transformed tobacco plants with the BrRZFP1 gene. Plants were regenerated from 82 independently transformed callus lines of tobacco and analysed for transgene expression. Transgene integration and expression was confirmed by Southern and RT-PCR analyses, respectively. T2 plants displayed more tolerance to the bacterial pathogens Pectobacterium carotovorum and Ralstonia solanacearum, and the tolerance levels were correlated with BrRZFP1 expression levels. These results suggest that the transcription factor BrRZFP1 is an important determinant of stress response in plants and its overexpression in plants could increase biotic stress resistance.

  • 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.

  • The purpose of this study is to investigate the determinants of blockholder presence in the Korean stock market. This study examines previous theories and studies, points that previous studies did not examine, and proposes two hypotheses. To verify two hypotheses, fundamental data were collected from firms listed on Korea Exchange from 2005 to 2017. As explanatory variables, we use the factors and characteristics of the firms used in the previous studies. Logistic regression analysis was conducted to test the determinants of blockholder presence. We find that firm size is the most distinctive factor determining the presence of blockholder, and firm idiosyncratic risk is the most similar factor determining the existence of each blockholder. Tobin Q shows significant value in family and government, and R&D intensity appears to be a negative related to the presence of blockholder in financial institutions. We also find that the determinant of blockholder presence differs from the mechanisms that govern each individual blockholder type when all blockholders grouped together. This suggests that there is blockholder heterogeneity within Korea listing firms. Our findings contribute to investors and policy makers who interested in the determinants of the presence of blockholder and blockhoder heterogeneity in Korea stock market.

  • Cancer metastasis is a major determinant of cancer patient mortality. Mounting evidence favors a strong positive role for $TGF-{\beta}$ in human cancer progression. The complex pattern on cross-talk of $TGF-{\beta}$ and the related other signaling pathways is an important area of investigation that will ultimately contribute to understanding of the bifunctional role of $TGF-{\beta}$ in cancer progression. This review summarizes some of the current understanding of $TGF-{\beta}$ signaling with a major focus in its contribution to the tumor cell invasion and metastasis. Five issues are addressed in this review: (1) $TGF-{\beta}$ signaling, (2) $TGF-{\beta}$ and EMT, (3) $TGF-{\beta}$ and MMP, (4) $TGF-{\beta}$ and Ras, and (5) Role of $TGF-{\beta}$ in invasion and metastasis. Due to the bifunctional cellular effects of $TGF-{\beta}$, as a tumor promoter and a tumor suppressor, more precisely defined $TGF-{\beta}$ signaling pathways need to be elucidated. According to the current literature, $TGF-{\beta}$ is clearly a major factor stimulating tumor progression through a complex spectrum of the interplay and cross-talk between various signaling molecules. Understanding the role of $TGF-{\beta}$ in invasion and metastasis will provide valuable information on establishing strategies to manipulate $TGF-{\beta}$ signaling which should be a high priority for the development of anti-metastatic therapeutics.

  • The main purpose of this study is to investigate factors that influence sleep duration and sleep time poverty in terms of family characteristics, child characteristics, and time use. A series of data analyses were conducted on children's time use in two-parent families based on the 2013 Korean Children and Youth Panel Survey. One major finding is that children's sleep duration and the probability of having a sleep time poverty are related to their mothers' job classifications. The factors influencing the duration of sleep time and the sleep time poverty are similar in terms of family characteristics and children's time use. The mother's job classification, family income, number of younger siblings, number of older siblings, children's private tutoring hours, computer game hours, and TV hours are statistically significant factors affecting the duration of sleep time and the probability of having a sleep time poverty. However, the factor with greatest influence on sleep time duration is private tutoring hours and the factor most affecting sleep time poverty is computer game hours. The mother's job classification is a relatively powerful determinant for predicting her children's sleep duration and sleep time poverty.

  • Considering how an organization is timely competitive for survival in the rapidly changing environment of today, it is more important to get new information and knowledge continuously by teams. However team system provides organization with opportunities and, at the same time, is provoked into conflict by the diversity of team members. This study examines the effect of team diversity on knowledge creation and investigates the influence of absorptive capacity and conflict as mediators. The sample population consisted of officials who work in teams at two business corporations that have successfully achieved knowledge creation. The result presents team diversity serves as an effective factor for absorptive capacity and absorptive capacity also serves as an effective factor for knowledge creation. In contrast, team diversity brings team members into conflict and conflict has a negative effect on knowledge creation. Another significant finding of this research is the fact that a positive effect of absorptive capacity on knowledge creation is greater than a negative effect of conflict on it. It clearly demonstrates that team diversity can be an important determinant of knowledge creation if an organization tries to reduce team member's conflict.

  • Purpose : This study was to analyze the demand for emergency ambulance service and to characterize the factors associated with the demand. Method : The basis for the model was from the actual demand for public emergency ambulance and socioeconomic and geographic characteristics. Multiple regression analyses were done for the related characteristics of public ambulance service. Result : The model explained total demand with a high degree of accuracy : the coefficient of determination($R^2=0.96$). For the regression, the set of variables indicative of low socioeconomic status were all significant. It showed the inappropriate use of public ambulance system. Public ambulance demand increased in higher housing density, low income, male unemployment and female labor force. Conclusion : The demand for public ambulances appeared to be highly predictable, using a simple linear model employing socioeconomic variables, quality of service variables, and land use variables. Low-income families tended, to use the public ambulance system more often than higher income. Area having elderly people or children also made many calls. Estimated demand calls were stable and had a tendency to be similar incident types.

  • The current higher education in Vietnam demonstrates the intense competition among local universities. Undoubtedly, the issue of enhancing the brand value to attract students is now placed at the top to Vietnamese universities. The research aims to identify the objective and subjective factors affecting the brand value of private universities in Ho Chi Minh City, Vietnam as mediated by students' perceptions. This paper employs the mixed research methods and data were then analyzed by measuring Cronbach's Alpha coefficient for reliability, analyzing EFA, and using PATH model to test the experiment on the research model affecting HUTECH's brand value. Probability sampling used is Stratified sampling and 500 students of 8 faculties of HUTECH surveyed by convenience sampling. Additionally, this paper also proposes some managerial implications on enhancing the brand value of private universities in Ho Chi Minh City. The results indicate that the new factor, namely geographic location is the most influential factor to enhance the brand value of private universities in general and HUTECH in particular. Brand still plays a determinant role in students' trust when choosing a university. Finally, some implications proposed to enhance the brand value of private universities in Ho Chi Minh City in the context of fierce competition in attracting students.
