The purpose of this study was to derive the factors that affect the development cost and the priority/weight of effectiveness in the pre-development stage of a service robot to estimate the development cost. In particular, the functions of service robots vary according to the field of application, and their prices are not only different but most of them are small-scale production; hence, a cost estimation is necessary. In this research, the factors affecting the service robot development cost in the process of service robot development and adding functions are classified as a functional factor while the factors that affect the entire development cost due to environmental causes, in which the service robot is operated or in the development process, are classified as an adjustment factor. The FGI was conducted to derive the factors and a Delphi survey was conducted among 84 domestic experts to determine the weights of the factors. As a result of the analysis, six functional factors (41 detailed criteria) and five adjustment factors (17 criteria) were derived, the cost weight and rank of the factors were suggested. This study suggests that the development cost of the service robot can be used as a decision-making strategy to select the operation functions in the development process, and can be utilized as an essential tool for the service robot development.

This study aims to examine validity and reliability of the convergence talent measurement. Based on the comprehensive literature review on convergence and convergence talent, we draw 4 main competencies (convergence cognitive, accomplishment, problem solving, and attitude) and 10 critical aspects (creative thinking, critical thinking, cooperation, communication, problem-solving, knowledge accessibility, resource utilization, trust, openness, caring) for building an effective convergence-oriented organization. A validity and reliability test survey were conducted for the analysis to investigate the convergence talent scale. With a data of 151 employees in diverse companies, the results show that the factors demonstrated acceptable levels of validity and reliability. The empirical evidences of our study are 10 key aspects comprising four main dimensions which suggest an available scale for measuring the convergent talent for enhancing convergence-oriented organizations. Our research contributes to the expansion of academic and practical implications on convergence, especially in convergence-oriented organizations.

The aim of this study was to analyze the contribution factors (backfat thickness, eye muscle area, carcass weight, marbling score, and feeding period) affecting meat unit price (South-Korean Won / Kg of meat). The best slaughtering age to maximize unit price was also assumed. All data used in this study were acquired from the Korea Institute for Animal Products Quality Evaluation from 2010 to 2014. Contributions to the estimated unit price of cows by the following factors, backfat thickness, eye muscle area, carcass weights, feeding period, and marbling score were 2.65%, 0.04%, 1.58%, 1.58%, and 95.72%, respectively. Contribution to estimated unit price of steers by the same factors (backfat thickness, eye muscle area, carcass weights, feeding period, and marbling score) were 7.88%, 1.24%, 0.07%, 90.81%, and 95.72%, respectively. Slaughtering ages ranged from 26 to 36 months and the data were separated into each month for an 11 month period. The unit price of meat from Hanwoo slaughtered at 30 months was highest among groups. The lowest unit price was observed in the group belonging to the Hanwoo slaughtered at 36 months. In conclusion, of all contributing factors, marbling score affected unit price the most. Based on our results, it is recommended that the optimal slaughtering age be set at 30 months to maximize unit price. Moreover, the feeding of beef cattle past 30 months of age is not recommended because of the increase in feeding costs.

This study was done to identify the significant convergence factors of affecting depression of elderly women in rural area. A total of 161 elderly women aged 65 and over were collected and data were analyzed using multiple logistic regression with SPSS/WIN 21.0. The result indicated that 42.9% of participants were depressed. In logistic regression, significant factors of depression were age(p<.001, OR=1.146), economic status (p=.004, OR=.123), number of family member living together (p=.013, OR=.020), number of social activities (p=.012, OR=.436), number of disease diagnosed (p<.001, OR=3.847), visual function (p=.023, OR=3.867), family support (p=.048, OR=.707), which accounted for 68.6% of the variance. The results of this study can contribute to develop various convergence strategies to prevent the prevalence of depression of elderly women in rural area. Further studies are needed to confirm the level of contribution of visual disability to depression in rural older women.

The purpose of this study is to identify the convergence factors affecting the unmet health needs of the indigent elderly. The data the study is the Korean medical panel of 2011 and the parameters belonging to each factors were selected based on the Anderson model. We analyzed the general characteristics using frequency analysis and the correlations between variables using cross analysis. Finally, logistic regression analysis was conducted to examine the factors affecting unmet health needs. The indigent elderly with no education and elementary school graduates were 1.5 times more likely to experience unmet health needs than the poverty elderly with high school graduates. The indigent elderly who does not work for income, who were employers and self-employeds were 1.5 times more likely to experience unmet health care need than unpaid family workers. The indigent elderly with disabilities in activites of daily living were 2.9 time more likely to experience unmet health care needs than the indigent elderly with no disability in activites of daily living. The results of this study confirm that the increase in the economic burden of medical care for the indigent elderly can lead to the unmet health needs.
