Recently, studies on the fourth industrial revolution have been actively conducted in the areas of government, business, and academia. Corporate business models that utilize the major agendas of the fourth industrial revolution such as robots, artificial intelligence, Internet of things (IoT), and block chains have been created, and various changes have occurred in not only business, education, and living environments but also in international relations. In this study, we looked at changes in social contribution activities from the perspective of a company facing impacts of the fourth industrial revolution. This study examines the definition and activities of corporate social contribution and how we can contribute to society through corporate activities. 'AT Educom', LG Uplus 'Social Contribution through IoT', KT's anti-infectious disease prevention platform and cases of Intel using IoT. In addition, we have presented what we need to do in the future to promote corporate social contribution activities that will make more meaningful impacts on how corporate social contribution activities will change according to technology development. The first, measuring the performance of corporate social contribution activities needs a standardized methodology and social contribution activities through platform business and ICT should be actively pursued. Lastly, social contribution activities between companies and sectors will increase.

The majority of existing studies for quantifying uncertainties in climate change impact assessments suggest only the uncertainties of each stage, and not the total uncertainty and its propagation in the whole procedure. Therefore, this study has proposed a new method, the Uncertainty Delta Method (UDM), which can quantify uncertainties using the variances of projections (as the UDM is derived from the first-order Taylor series expansion), to allow for a comprehensive quantification of uncertainty at each stage and also to provide the levels of uncertainty propagation, as follows: total uncertainty, the level of uncertainty increase at each stage, and the percentage of uncertainty at each stage. For quantifying uncertainties at each stage as well as the total uncertainty, all the stages - two emission scenarios (ES), three Global Climate Models (GCMs), two downscaling techniques, and two hydrological models - of the climate change assessment for water resources are conducted. The total uncertainty took 5.45, and the ESs had the largest uncertainty (4.45). Additionally, uncertainties are propagated stage by stage because of their gradual increase: 5.45 in total uncertainty consisted of 4.45 in emission scenarios, 0.45 in climate models, 0.27 in downscaling techniques, and 0.28 in hydrological models. These results indicate the projection of future water resources can be very different depending on which emission scenarios are selected. Moreover, using Fractional Uncertainty Method (FUM) by Hawkins and Sutton (2009), the major uncertainty contributor (emission scenario: FUM uncertainty 0.52) matched with the results of UDM. Therefore, the UDM proposed by this study can support comprehension and appropriate analysis of the uncertainty surrounding the climate change impact assessment, and make possible a better understanding of the water resources projection for future climate change.

The purpose of this study was to understand science teaching experiences of elementary school teachers who taught the system thinking-based science inquiry class. The phenomenological methods were applied to analyze four elementary teachers' meaningful experiences. The four step methods of phenomenological experience research proposed by Giorgi (1985) and interview questions developed by Seidman (1998) and Schuman (1982) were used in order to collect qualitative data. The major findings of this study were as follows: First, teachers intentionally tried to ask divergent thinking questions which promoted the system thinking in classes. The teachers used divergent thinking questions to promote their students' thinking activities and to induce students' system thinking. In addition, the receptive mood created by teachers and interactive environments had a positive effect on promoting system thinking skills. Second, teachers remarked lack of teaching and learning materials and difficulties in selecting themes of their classes in order to teach the system thinking-based science inquiry class effectively. In addition, it was very difficult for teachers to evaluate the contents and processes of students' learning correctly because there were little evaluative tools and methods readily available. The findings indicated that there were some limitations in maximizing the effects of system thinking-based science inquiry instruction due to elementary students' inappropriate process skills of inquiry activities. Findings of this study revealed significant insights about elementary school teachers' experiences regarding the system thinking-based science class.

This study is aimed to find out the effect of PAPS-D on physical fitness of developmental disabled students who participated of Inline skate program. The subject of this study was 10 middle and high school students diagnosed as developmental disability. The subject attended a total of 32 classes twice a week for 16 weeks and the class was 1 hour each time. Improvement of physical fitness was assessed based on PAPS-D program developed by the Department of Education science in 2016 except for obesity measurement; cardio pulmonary function (walking in 6 minutes), flexibility (seated forward bend, clasped hand behind the back), muscle function (sit-up) and agility (standing long jump). To find out the interaction between control group and experimental group, two-way repeated measure ANOVA was used. As a result, there was a statistically significant relation in cardio pulmonary function and agility but not in flexibility and muscle function. 3 variables (cardio pulmonary function, flexibility and muscle function) among 4 variables showed positive effect of Inline skate program on physical fitness while one variable which was agility showed decreased result in post-test. Based on the results of three variables that were found to have improved in the pre post-examination, the result of this study indicates positive effect of Inline skating program on physical fitness of developmentally disabled students.

Purpose: In this study, the hospice nursing research trend in 1998~2017 was investigated by analyzing research articles on hospice nursing. Methods: Literature search was performed with keywords of 'nursing' and 'hospice on an academic research information service. Also reviewed were all articles published in the Korean Journal of Nursing Science and its 8 subcategory journals, the Korean Journal of Hospice and Palliative Care and the Korean Hospice Association from 1998 through 2017, except thesis papers. Results: In 2013~2017, 79 articles (31.0%) were relevant, up over 7% from 61 articles (23.9%) in 2008~2012. The most studied field was psychology (92 papers, 36.2%) in the Korean Journal of Hospice and Palliative Care. Enrolled in most papers were patients with end-stage cancer (75, 29.5%), which is overwhelmingly high. Most studies used quantitative methods (183, 72.0%). Recognition was the most studied theme (62, 24.4%), and 16 of them focused on recognition of death (6.3%). Intervention studies totaled 34 (13.4%), and most of them (7, 2.8%) were conducted for palliative education. Conclusion: Most hospice nursing studies were quantitative studies, conducted with patients, and hospice nursing intervention programs were similar to each other. Thus, more studies with hospice patients and their families are needed. And more experimental and qualitative studies are needed to build an evidence-based nursing study environment. Considering how most studies examined psychological factors, physiological factors such as pain, a major issue in hospice care, should be analyzed in experimental studies to construct a pain intervention program for hospice patients.

The extant research literature is scant in telling us how organizations actually implement lifelong learning practices and policies. Hence, the purpose of this paper is to describe how lifelong learning is grounded in practice. We do this by introducing a new conceptual framework that was developed on the basis of interviews with a number of leading edge corporations from Canada, the USA, India and Korea. At the heart of our model, and any effective lifelong learning system, is a performance management system. The performance management system allows for an ongoing interaction between managers and employees whereby challenging performance and learning goals are set, and concrete plans are made to achieve them. Those plans involve three types of learning activities. First, employees may be encouraged to engage in formal learning. This could be provided in-house, or the employee may take a leave of absence and return to school. Second, managers may deploy their subordinates to different departments or teams, so that they can take part in new work-based learning opportunities. Finally, employees may be encouraged to learn on their own time. By this we mean learning after organizational hours through firm-sponsored 5 programs, such as e-learning courses. Fueled by the performance management system, we posit that these three learning outlets lead to effective lifelong learning in organizations.

There are beautiful scenery with columnar jointing at 15 valley of southern slope of the Wangtian'e volcano in Mt. Baekdu volcanic field. The compositions of phenocryst minerals which have porphyritic textures in mafic volcanic rocks of this area were carried out. The Wangtian'e volcano consists of Changbai basalt~trachybasalt (lower part) and Wangtian'e basaltic trachyandesite~trachyte~alkali rhyolite (upper part). This study is focused on the mafic rocks of the Changbai trachybsalt and the Wangtian'e basaltic trachyandesite. Main phenocrysts are feldspar, pyroxene and olivine. The major element compositions of the phenocrysts were analyzed using EPMA. Plagioclase phenocrysts of the Wangtian'e basaltic trachyandesite are located at the border of andesine and oligoclase ($An_{24.1{\sim}36.0}$) in the An-Ab-Or diagram, and those of the Changbai trachybasalt are labradorite ($An_{54.2{\sim}65.2}$). Pyroxene phenocrysts are augite. Olivine phenocrysts of the Changbai trachybsalt are crysolite ($Mg_{0.79-0.77}Fe_{0.21-0.23}$) and microphenocrysts in the groundmass are hyalosiderite ($Mg_{0.58-0.56}Fe_{0.42-0.44}$). Calculated crystallization temperature of olivine phenocrysts is $1196{\sim}1123^{\circ}C$, clinopyroxene is $1122{\sim}1112^{\circ}C$, phenocrysts and laths of plagioclases are $1118{\sim}1107^{\circ}C$ and $1091{\sim}1089^{\circ}C$, respectively. The temperatures suggests that the olivine phenocrysts, clinopyroxene, plagioclase phenocrysts, and plagioclase laths were crystallized in the magma chamber in sequence.

The expansion of the performing arts market to include new genres of art that combine art and cutting-edge media technology has surpassed the limitations of traditional theatre art elements such as stage, costumes, lighting, sound, and props, allowing free expression of space-time and visual art. It is growing into a wide area with unlimited potential in the performing arts sector. In response to these changes and the demands of the time, there is an increasing demand for multi-talents who can plan and produce arts and technology-converged contents that will contribute to the development of the performing arts industry. As a result, university departments related to theatre art across the country feel that it is urgent to develop curricula that will enhance students' competency by incorporating the latest media technologies such as virtual reality, holography, and interactive motion sensors into the existing performance art visualization process. In this study, the author will examine the process of developing courses in technology-incorporated theatre art (design) through case studies of media technology-converged performances from the past 10 years. Based on the traditional concept of theatre art, the attempt to fuse stage art with media technology will be a cornerstone of attempts to foster a group of talented artists who transcend the limits of creative visual expression and creative value.

In order to increase the probability of success in big data projects, quantified techniques are required to analyze the root cause of risks from complex causes and establish optimal countermeasures. To this end, this study measures risk factors and relationships through SNA analysis and presents a way to respond to risks based on them. In other words, it derives a dependency network matrix by utilizing the results of correlation analysis between risk groups in the big data projects presented in the preliminary study and performs SNA analysis. In order to derive the dependency network matrix, partial correlation is obtained from the correlation between the risk nodes, and activity dependencies are derived by node by calculating the correlation influence and correlation dependency, thereby producing the causal relationship between the risk nodes and the degree of influence between all nodes in correlation. Recognizing the root cause of risks from networks between risk factors derived through SNA between risk factors enables more optimized and efficient risk management. This study is the first to apply SNA analysis techniques in relation to risk management response, and the results of this study are significant in that it not only optimizes the sequence of risk management for major risks in relation to risk management in IT projects but also presents a new risk analysis technique for risk control.

Purpose - The major objective of this study was to investigate the effect of franchisor's (economic and philanthropic) CSR in inspiring franchisee's loyalty for the franchisor. Another aim of this investigation also was to clarify the mediating role of economic and social satisfaction in the relationship between franchisor's CSR and franchisee's loyalty. Research design, data, and methodology - This study explores the structural relationship between franchisor's CSR and franchisee's loyalty and in these relationships, the mediating role of relationship satisfaction. Data were gathered from employees(above manager) in food-service franchisee companies in Seoul, Korea. The questionnaires were distributed to managers of the franchise stores. A total of 251 questionnaires were collected. Data management and analysis were performed using SPSS 21.O and SmartPLS 3.0. Evaluation of measurement model and structural model was carried out using confirmatory factor analysis and correlation analysis. Result - The results of this study show as follows. First, economic CSR had positive effects on economic satisfaction and social satisfaction. Second, philanthropic CSR had positive effects on social satisfaction. Third, economic satisfaction and social satisfaction had positive effects on franchisee's loyalty to the franchisor. Conclusions - The important implications of this study have as follows. First, this study has found that economic CSR can create a high economic satisfaction and social satisfaction of franchisee. Second, this findings suggest that the philanthropic CSR can improve the social satisfaction of franchisee. Third, this results demonstrate, for the first time, that the economic satisfaction and social satisfaction of franchisees can play a crucial role to improve their loyalty for the franchisor and pursue mutual development by maintaining the stable business relationship with a franchisor. In this investigation there are at least three limitations. First, Because the research sample is limited to the foodservice franchisee in Seoul, it is not possible to be representativeness of the national franchisee. Second, CSR activities are mostly focused on large franchise companies. Therefore, there is a limit to the research approach. Finally, this study examined the effect of economic CSR and philanthropic CSR on the loyalty of franchisors, but in the future study, it is necessary to analyze the relationship between CSR and loyalty of franchise companies by collecting specific quantitative data such as re-contract rate and management performance of franchisees.
