This study was attempted to identify the differences in convergence variables that affect wage workers and self-employes' quality of life. The 2013-2017 National Health Nutrition Survey data were used. This study found the factors that affected the quality of life of wage workers were age, economic status, number of family members, marital status, feeling of depression, subjective health status (F = 5.06, p <.001.). Factors that affected the quality of life of self-employed were age, frequency of lunch, frequency of drinking, strength exercise day, BMI, Subjective body shape perception, stress and subjective health status (F = 8.60, p <.001). The results of this study show that in order to develop nursing interventions to improve the quality of life for workers, their characteristics and physical and psychological factors should be taken into account.

This study aims to review previous research on the key elements of an Initial Coin Offering (ICO) and establish their priorities in order to help relevant stakeholders build and invigorate an ecosystem that integrates blockchain technology with the digital content industry. To achieve this goal, we first structured the key elements identified from previous studies into a hierarchy model. We then assigned weighted values to each element using the Analytic Hierarchy Process (AHP) methodology. Among the main elements, the priorities were identified as follows, from most important to least: Business (0.422) > Technology (0.172) > Contents (0.144) > Human Resources (0.104) > Institutions (0.099) > Token (0.059). With regard to the sub-elements, the weighted values were found to be as follows, in descending order: Probability (0.162) > Laws and Regulations (0.071) > Estimated Growth (0.063). The implications of the results are also described within the present study. The findings of this study will be of great value to ICO founders as well as investors and provide a much-needed academic basis for the burgeoning blockchain-integrated ecosystems and businesses.

In the wireless localization systems using range measurements, iteration method-based approximated solutions have been used. Also, linear closed-form solutions have been investigated in the light of local minimum problem and computational load. However, each closed-form solution has individual error factors that cause usage limit of the solutions. In this paper, a fusion method integrating two representative closed-form solutions is presented. The presented method cancels the error factors of each solution out. Weights for integrating the standalone solutions are determined using the error factors-based fuzzy method. The performance of the proposed method is verified using some simulation results.

본 연구의 목적은 최근 증가하고 있는 고령 인구를 위해 여러 가지 요인을 고려하여 노인만을 대상으로 하는 여가 만족도를 산출하는 것이다. 노인의 여가 만족도에 영향을 주는 요인으로 '여가시설', '노인 인구', '노인 건강', '노인 소득'을 산정하였다. 해당 요인들에 가중치를 분배하여 산정하기 위한 방법으로 PCA와 선형회귀를 사용하였다. 위 과정을 통해 제작된 노인 여가 만족도 지표에 인자값을 투입하여 자치구별로 노인 여가 만족도 점수를 산출하였고, 스코어 카드를 통해 현황을 살펴보았다. 본 연구는 산출된 각 자치구별 여가 만족도 점수와 인자에 해당하는 점수를 파악하여, 여가만족도가 낮은 지역들의 취약 분야를 파악하고 취약 분야를 중점으로 여가 만족도를 개선해나갈 것을 제안한다.

The purpose of this study is to investigate how the impact on the basic psychological needs and emotional and motor sports commitment to participate in 12 weeks of Physically Disabled wheelchair tennis class. Results: First, the basic psychological needs is a difference between groups was found in the autonomy and the relationship of the sub-factors autonomy, competence, was the difference in time measured between the castle. Second, the movement was born immersed in the measuring point to see a difference in cognitive involvement and engagement of sub-behavior factors, the mutual effects were measured at the time of the two groups and sub-factors. Third, the movement was born in sentiment appears to have overlooked the measurement point in the sub-group differences in factors such as positive emotions and negative emotions, collective and cross effects were measured at the time of the two sub-factors. Subsequent studies in qualitative research, as well as be able to induce a more active ongoing participation of the disabled being difficult to draw parallel with the subjective experience of people with disabilities, it is thought to be possible to develop a variety of programs.

This study was conducted to identify convergence factors affecting depressive symptoms of postmenopausal women through the theory unpleasant symptom. This study was secondary data analysis form Sixth Korea National Health and Nutrition Examination Survey 2015. Study sample of 1,298 menopausal women to evaluate the factors that would influence depressive symptoms, physiological factors, situational factors, and psychological factors. The results showed that significant variables influencing the depressive symptom were income quartile(${\beta}=-.14$, p<.001), health status(${\beta}=.24$, p<.001), and stress(${\beta}=-.20$, p<.001). The explanation power of this regression model was 14. 1% and it was statistically significant. As a result, to improve their depressive symptoms, the nursing interventions are required for postmenopausal women who have the income, health status, and stress.

The study is investigated socioeconomic variations in perceived oral health status and contribution of oral health behavioral factors. A nationally representative sample (365 health and 1,787 unhealth aged 20 over years) from the 2015 Korea National Health and Nutrition Surveys was analyzed using logistic regression. Perceived oral health was lower among lower socioeconomic groups compared with higher socioeconomic groups. This association was increased when demo-socioeconomic factors and oral health behavioral were adjusted. When each oral health behavioral factor was considered separately, mediators such as smoking, frequency of tooth brushing and used oral care products or oral health examination explained a large part of the increased socioeconomic oral health status. Subjective bad oral health arise from different socioeconomic status, but this difference is increased by oral health behavioral factors. Therefore, socioeconomic inequity in perceived oral health status can be corrected more effectively by promotional oral health behaviors.

This study was conducted to find out the factors influencing the subjective perception of some students majoring in dental hygiene. An online survey was conducted on 292 enrolled students, and the data were analyzed using SPSS 22.0. As a result of multiple regression analysis of the factors influencing subjective perception, the factors that significantly influence were positively influenced by admission according to general satisfaction, subject satisfaction, and aptitude. Therefore, it is necessary to improve the subjective perception of enrolled students through improvement of various factors. To this end, it is considered necessary to raise positive awareness and provide customized employment guidance by establishing various education and counseling support programs suitable for the subjects through continuous research in the future.

The purpose of this study was to analyze the effect of service factors of used book transactions, which are becoming a major service in online bookstores, on customer satisfaction and the effect of customer satisfaction on reuse intention. 235 samples were collected through a survey for users of used book transaction services in their 20s or older, and 205 surveys were adopted through the refining process. Hypotheses were verified through factor analysis, reliability analysis, and structural model analysis using SPSS22.0 and AMOS22.0 statistical programs. Some factors were supported between service factors and customer satisfaction, and customer satisfaction had a significant effect on reuse intention, and moderating effects according to the preferred genre of reading were founded. More differentiated services should be considered according to the customer's preferred genre, as the services of online bookstores are becoming more standardized, customers do not feel differentiated.
