The purpose of this study was to explore the influencing factors of consumption behavior of healthy functional foods including vitamin/mineral products for overweight and obese Koreans. Overweight and obese Koreans were selected based on the body mass index(BMI) from the KNHANES that was collected in 2007. Probit estimation model was used to find the influencing factors such as age, gender, job, education, income, nutrition education, and cultural capital(parents' education) on consuming the healthy functional foods. Overweight consumers were found to consume vitamin/mineral products and healthy functional foods at 17.5% and 22.7%, respectively. Obese consumers were found to consume vitamin/mineral products and healthy functional foods at 18.2% and 22.8%, respectively. In addition, self decision was found to be a significant factor to consume both products in both groups. Nutritional education and job were significant factors to consume vitamin/mineral products in overweight consumers, while mother's education and job(service) were significant factors in obese consumers. Weight control for body shape, gender, age, and income were significant factors to consume healthy functional foods in overweight consumers, while nutrition label and perceived health status were significant for obese consumers. Therefore, providing consumer information on functional foods might be useful for consumers to consider the healthy functional foods as an available option to purchase. Various influencing factors between two groups might be concerned to develop different strategies for promoting the healthy functional foods consumption including vitamin/mineral products.

Purpose: Korea is one of the most rapidly aging countries, accompanied by an increasing number of older adults with dementia. Certified-care-assistants are the primary care workers for these older adults. This cross-sectional descriptive study compared the factors influencing care behaviors among Korean and non-Korean certified-care-assistants in Korea. Methods: Participants, 113 Korean certified-care-assistants and 71 non-Korean certified-care-assistants, completed a survey questionnaire. The questionnaire was designed to assess dementia knowledge, attitude and care behaviors toward older adults with dementia. To determine the differences in these two groups, t-test was used. A stepwise multiple regression was performed to identify factors related to care behavior. Results: Significant differences in dementia knowledge, attitude and care behavior toward older adults with dementia emerged between Korean and non-Korean certified-care-assistants. Factors influencing care behavior varied by group. Dementia knowledge and education level were the significant factors of care behaviors in Korean certified-care-assistants, whereas attitude toward older adults with dementia was the significant factor in non-Korean certified-care-assistants. Conclusion: Findings indicate that different factors influence the care behavior of two groups. These findings can be utilized to develop certified-care-assistants' training curriculum that needs to be tailored by nationality to improve the quality of care for older adults with dementia.

Purpose: The purpose of this meta-analysis isto identify social psychological factors related to quality of life and estimate the effect sizes of the factors among patients with strokes. Methods: Thirteen studies with a total of 1,814 patients published from the earliest records to January 8, 2017 were selected through a systematic process of searching the literature, and evaluated against influencing factors of quality of life and their effect sizes. Pooled effect sizes were calculated using the random effect model. Meta-analysis was conducted by R software. Results: The following influencing factors had a strong association with quality of life with stroke: depression (r=-.50; 95% CI: -0.63~-0.46), activities of daily living (r=.46; 95% CI: 0.35~0.56), and social support (r=.40; 95% CI: 0.24~0.53). Conclusion: The findings confirm that depression, activities of daily living and social support are associated with quality of life among patients with stroke survivors. We recommend that any intervention program to improve the quality of life with stroke patients consider addressing these modifiable influencing factors.

Background: With increased interest in oral health, several efforts have been made to improve oral health conditions. To achieve this, needs for oral health must be precisely determined and accurately measured. Therefore, factors influencing both objective unmet dental needs, which were determined by experts, and perceived unmet dental needs, which were determined by patients, were examined in this study. Methods: Responses of 17,735 respondents aged greater than 19 years from the Korean National Health and Nutrition Survey collected using the fifth (2010~2012) rotation sample survey were analyzed. Based on the information collected from the survey and dental examination, we determined the associations between the independent (sex and socioeconomic level) and dependent variables using a chi-squared test. Moreover, ordinal logistic regression analyses on multiple categorical values were performed using perceived and objective dental needs as the dependent variables. Results: Generally, factors influencing both perceived and objective dental needs were similar. These included sex, household income, educational level, private insurance, and subjective oral health status. However, the high-income groups had lesser perceived and objective dental needs compared to the low-income groups. Furthermore, factors such as sex, educational level, and marital status had different influence on both needs. Conclusion: Generally, factors that affect perceived and objective dental needs were similar. To minimize unmet dental needs, factors influencing both perceived and objective dental needs should be examined for a broad dental insurance coverage, and efforts to prevent oral diseases are also required.

Since reliability and security of man-machine system increasingly depend on reliability of human, human reliability analysis (HRA) has attracted a lot of attention in many fields especially in nuclear engineering. Dependence assessment among human tasks is a important part in HRA which contributes to an appropriate evaluation result. Most of methods in HRA are based on experts' opinions which are subjective and uncertain. Also, the dependence influencing factors are usually considered to be constant, which is unrealistic. In this paper, a new model based on Dempster-Shafer evidence theory (DSET) and fuzzy number is proposed to handle the dependence between two tasks in HRA under uncertain and dynamic situations. First, the dependence influencing factors are identified and the judgments on the factors are represented as basic belief assignments (BBAs). Second, the BBAs of the factors that varying with time are reconstructed based on the correction BBA derived from time value. Then, BBAs of all factors are combined to gain the fused BBA. Finally, conditional human error probability (CHEP) is derived based on the fused BBA. The proposed method can deal with uncertainties in the judgments and dynamics of the dependence influencing factors. A case study is illustrated to show the effectiveness and the flexibility of the proposed method.

Influencing factors on flexural toughness of ring-type fiber reinforced concrete(RSFRC) are investigated. An experiment proceeding ASTM C 78 is peformed to make a comparison between ring-type fibers and double-hook type fibers. Most specimen with ring type fibers have failed by the cone type failure, while discrete hook type fibers have failed by fiber pullout. For the hook-type fiber reinforced concrete(SFRC), the first crack load increases, as the fiber mixing volume increases. Aspect ratio(fiber length/fiber diameter) is critical for hook type fibers, so the flexural toughness increases significantly, as the length of fiber increases. However, for the ring type, the toughness indices Increase as the number of fibers in the specimen increases. Since there is no bond problem between the ring fiber and the concrete matrix, the aspect ratio does not affect the performance of the composite material with the newly developed steel fibers. Influencing factors with respect to flexural toughness RSFRC were observed to be ring diameter, diameter of steel fiber and fiber content.

Purpose: The purpose of this study was to identify the factors influencing fatigue in patients with chronic obstructive pulmonary disease. Methods: A descriptive correlational study design was used. A convenience sample of 125 subjects was recruited from the outpatient respiratory clinic at a large university hospital. Data was collected from June to October, 2005 using structured questionnaires, an oxygen saturation test, a 6-minute walking test, and a pulmonary function test. Results: Subjects had a slightly low degree of fatigue. The fatigue showed a significant correlation with emotion(r=.589, p= .000), dyspnea(r=.304, p= .001), self-efficacy(r=-.278, p= .002), and symptom experience(r=.238, p= .008). Emotion(34.7%) and dyspnea(5.8%) were significant predictors to explain fatigue. Conclusion: This study provides comprehensive understanding of the influencing factors on fatigue in patients with chronic obstructive pulmonary disease. Nursing interventions to decrease negative emotion and dyspnea for management of fatigue is suggested.

This study was conducted to identify the characteristics of fatigue and its influencing factors in patients having chronic arthritis. The subjects of this study were 120 patients who visited a Rheumatis Center of H University Hospital. Data were collected from Aug. 9, 1997 to Feb. 5, 1998. For analysing data, SPSS/Win was used for descriptive statistics & Pearson's correlation coefficient, and Lisrel 8.0 was for path analysis. The findings were as follows : 1. Mean score of subjective fatigue was 5.36 and it means moderate degree of fatigue. 2. Fatigue showed positive relationship with pain & depression, and it showed negative relationship with ADL & self efficacy. 3. Fatigue was influenced by pain and depression. and was not influenced by ADL and self efficacy directly. But ADL and self efficacy influenced on fatigue through pain and depression indirectly. According to this findings. the significant influencing factors of fatigue were pain and depression, therefore the development of nursing intervention for relieving pain and depression would be needed.
