Purpose: The purpose of this study is to identify the spatial distribution of hypertension prevalence and to investigate individual and regional-level factors contributing to the prevalence of hypertension in the region. Methods: This study is a cross-sectional research using the 2015 Community Health Survey. Total 64,473 people from 7 metropolitan cities were used for the final analysis. Geoda program was adopted to identify the regional distribution of hypertension prevalence and analyzed by descriptive statistics, one-way ANOVA and correlation analysis using SPSS statistics 23.0 program. Multi-level analysis was performed using SPSS (GLMM). Results: The prevalence of hypertension was related to individual level factors such as age, monthly household income, normal salt intake, walking practice days, and regional level factors including number of doctors per 10,000 population, number of parks, and fast food score. Besides, regional level factors were associated with hypertension prevalencies independently without the effects of individual level factors even though the influences of individual level factors ware larger than those of regional factors. Conclusion: Respectively, both individual and regional level factors should be considered in hypertension intervention programs. Also, a national level research is further required by exploring various environmental factors and those influences relating to the hypertension prevalence.

The study investigates some psychological and environmental factors affecting the intention to purchase organic foods of consumers in the inner-city of Hanoi. Impact factors applied for the study include three psychological factors (health concern, environmental concern, consumer awareness of organic foods) and seven environment factors (family's opinion, friends and colleagues' opinion, influence of celebrities, expert's opinion, social status, mass media, state's encouragement). We analyzed research data from 396 consumers to measure the impacting level of these factors. The convenient sampling method was used to collect the research sample. The measurement applied a 5-point Likert scale classifying from 1-completely disagree to 5-completely agree. Based on previous studies, the research model was recommended. We had estimated the reliability of the scales through Cronbach's Alpha and composite reliability. The research data is analyzed by using Structural Equation Model method (SEM). The findings of the study suggest that psychological factors (health concern, environmental concern, consumer awareness of organic foods) had a significantly positive influence on consumer's purchase attention toward organic food. The results also revealed that environmental factors (family's opinion, friends and colleagues' opinion, influence of celebrities, expert's opinion, mass media) were positively linked to consumer's purchase attention toward organic food.

Objectives: The purpose of this study was to conduct a meta analysis of the previous studies on parental factors related to psychological and social maladjustment of school children and to examine the moderate effects of publication year using the meta-regression analysis. Method: Subjects of studies was academic journals and thesis published on 1996-Feb. 2016. Final result of selection was 353(122 journal articles, 231 master's thesis & dissertations) and total number of sampling was 126,776 school children. Results: Parental factors had medium effect sizes on psychological and social maladjustment of school children. Parental risk factors had bigger effect size than protective factors on children's maladjustment. There were a tendency that effect size of some parental factors were increased as publish year went by. Conclusions: Attachment, positive communication, and positive marital relationship were major protective factors which had reduced maladjustment of children. Psychological control and negative marital relationship were the strongest risk factors. The impact on parental factors on maladjustment of children were getting stronger recently.

This study examined the use of Facebook in United Arab Emirates. There were two objectives of this study. The first purpose was to identify the motive for the use of Facebook among people in U.A.E. This study conducted the survey using both qualitative and quantitative methods. One hundred eighty-three working people were used from the survey. Thirty-five questions identified from the interviews were used for the questionnaire design in quantitative method. Factor analysis showed six factors namely usefulness, usage, reliability, making new friends, ethical issue and openness of information. The total variance explained by all the factors was fifty-two percent. This study also examined the demographic variables whether they would play an important role in using the social network site. The study included two more variables, income and married status, which were not frequently examined by previous studies. MANOVA showed statistical significant differences (p < .01) across six factors. ANOVA results showed that gender variable affected only the factor of openness of information. Males were more likely to share their information compared to females. Income variable affected all the factors except the openness of information. The results showed that high-income people had the highest meanscores on three factors (usage, reliability, making new friends) while low-income people had the highest means on usefulness and ethical factors.Marital status had significant effects on usefulness, reliability, and ethical factors. Married people had the low scores on reliability and ethical factors. Lastly, education variable had no effect on all the factors examined.

The aim of this study was to suggest appropriate factors for production pattern making of women's clothing. Sample pattern designers and production patterners of 13 women's brands were individually interviewed about pattern making process and factors necessary. The results were as follows: The factors to be considered in pattern making were categorized in three groups. 1. Factors to be considered to achieve the correct use of specific materials: elasticity, shrinkage, lining and interlining 2. Factors to be considered to satisfy the design specifications: silhouette, dart distribution, collar and sleeve, trimming 3. Factors to be considered for better sewing quality: skillfulness of the sewer, sewing methods and sewing equipment. 4. Suggestions were made for appropriate factors. A focus-group-interview in pattern design has been interviewed to verify the suggested factors. The factors were presented as a guide to develop the production pattern. 5. For better usage of the factors, standardization were suggested for making process with necessary factors for jacket, skirt.

Objectives:The objective of this study was to examine the perinatal and developmental risk factors of attention-deficit hyperactivity disorder (ADHD) diagnosed with a structured interview among Korean children. Methods:The current study included 924 children (6-15 years) recruited from schools in five Korean cities or a child psychiatry outpatient clinic of Seoul National University Children's Hospital. The parents of the children completed the structured diagnostic interview for attention-deficit hyperactivity disorder, as well as questionnaires on perinatal and developmental risk factors. Results:Preterm delivery, severe maternal stress during pregnancy, change in primary care taker during the first three years, postpartum depression, and delayed first sentence showed a significant association with ADHD diagnosis. Conclusion:These findings suggest that perinatal and developmental factors contribute to development of ADHD in Korean children. Conduct of future research using a prospective design is needed in order to identify the causal relationship between observed risk factors and development of ADHD.

Purpose: The study aimed to examine quality of sleep in hemodialysis patients and explore physical, physiological, and psychological factors determining sleep quality. Methods: The survey was conducted among 165 patients on maintenance hemodialysis at a university hospital. Data were collected from July to October in 2015. The sleep quality and its related factors were assessed by standardized questionnaires, anthropometric measures, and lab tests after obtaining a written consent from the participant. Results: The mean age of the participants was 62.58 years old, and 67.9% of the participants experienced sleep disorders such as 'not falling asleep within 30 minutes' or 'frequently waking up at night'. Pain (t=-3.29, p=.007) and depression (t=-6.028, p<.001) were significantly different between the group with sleep disorder and the other without. The demographic factors (age, shared room, sleep during the day), physical factors (pain and symptom), and psychological factors (depression and trait and status anxiety) together explained 20.0% of variance in sleep quality. Conclusion: Sleep disorder was frequently experienced among the patients on maintenance hemodialysis. The effective nursing strategies should focus on sleep environment, pain and depression management. Further study is warranted to explore the effect of physiological factors related to the disease on sleep disorder in this population.

Background: Drug survival, defined as the time until discontinuation, is a parameter reflecting real-world therapeutic effectiveness. Few studies have examined the influence of economic factors on the drug survival of biologic agents for psoriasis, particularly in Asian countries. Objective: To determine the drug survival for ustekinumab in real-life settings and investigate the factors affecting drug survival for psoriasis patients in Korea. Methods: We evaluated 98 psoriasis patients who were treated with ustekinumab at a single center. We analyzed the efficacy and drug survival of ustekinumab. Cox proportional hazard analysis and competing risk regression analysis were performed to reveal the factors affecting the drug survival of ustekinumab. Results: The overall mean drug survival was 1,596 days (95% confidence interval [CI], 904~2,288). Among the 39 cessations of ustekinumab treatment, 9 (23.1%) patients discontinued treatment after experiencing satisfactory results. Multivariate Cox proportional hazard analysis revealed that paying on patients' own expense was the major predictor for the discontinuation of ustekinumab (hazard ratio [HR], 9.696; 95% CI, 4.088~22.998). Competing risk regression analysis modeling of discontinuation because of factors other than satisfaction of an event also revealed that ustekinumab treatment at the patient's expense (HR, 4.138; 95% CI, 1.684~10.168) was a predictor of discontinuation rather than satisfaction. Conclusion: The results of our study revealed that the cost of biologics treatment affects the drug survival of ustekinumab and suggested that economic factors affect the drug survival of ustekinumab treatment in Korea.

This study examines whether unmanned aircraft systems (UAS) operated in the context of UAS traffic management (UTM) can be properly operated in its flight environment. In detail, this study examines the influencing navigation factors affecting UASs during flight and examines factors affecting the navigation of UASs under UTM. After deriving various factors affecting navigation, their importance are determined by applying the analytic hierarchy process technique, and the important influencing factors are examined. For low-altitude UAS navigation, errors are classified into navigation-system and flight-technical errors, and a hierarchy is constructed for their sub-factors affecting the influencers. Through this, influencing factors for precise navigation of low-altitude UAS are analyzed, and high importance items are identified.

Objective: The purpose of this study was to analyze correlation effect size between Basic Psychological Needs (BPN) and factors affecting BPN. Methods: This research was reviewed and synthesized systematically by meta-analyse. Fifty-eight published studies between 2008 and 2016 were sampled and the effect sizes were acquired. Results: The major findings were as follows. In general, medium correlation effect sizes were found. Competency among sub-factors of BPN showed highest effects. Parental factor was more related to BPN than school and individual factors. Parenting behavior and family psychological backgrounds were the most crucial factors in the parental factors. School adjustment was the most critical factor in the school factors. In school grade, the elementary school was more related to BPN than junior high school and high school. Conclusion: Based on these results, we suggest a number of components for parent-education programs, and information for future research.
