  • In this study we use three-dimensional magnetohydrodynamic simulations to investigate how the dynamic state of emerging magnetic field is related to the twist of field lines. Emerging magnetic field forms a magnetic structure on the Sun where various kinds of activity such as solar flares, jets, and coronal mass ejections are observed. To understand the physical mechanism for producing such activity, we have to know the dynamic nature of this structure. Since flares are the manifestation of rapidly dissipating electric current in the corona, we also investigate the distribution of current density inside the structure and examine how it depends on the field-line twist. To demonstrate the dynamic structure of emerging magnetic field, we focus on the factors characterizing the geometric property and stratification of emerging magnetic field, such as the curvature of field line and the scale height of field strength. These two factors show that emerging field forms a two-part structure in which the central part is close to a force-free state while the outer marginal part is in a fairly dynamic state where magnetic pressure force is dominant. We discuss how the field-line twist affects the two-part structure and also explain a possible relation between electric current structure and sigmoid observed in a preflare phase.

  • In foreign countries, the use of containers has already been stabilized with their advantages utilized in various forms. Containers are also utilized in Korea as various forms of architecture, but domestic container buildings have poor public consciousness so as to be limitedly utilized as temporary structures based on economic efficiency. Besides, there is the lack of research and development on them. Particularly, despite the advantages of containers as housing facilities, the use of containers as short- or middle-term temporary housing is limited and does not spread. Also, compared to general housing, containers have lower quality of physical environment and even frequently bring about negligent accidents such as fire and electric shock. Thus, this study intends to identify the actual condition of using container houses, the problems in using them, and the direction of improving their residential environment. For this purpose, it analyzes the present condition and characteristics of domestic container housing, and derives conclusions from the focus group interview with 23 residents who have lived in Seoul and Gyeonggi-do for over a year about such survey items as daylighting, ventilation, privacy condition, water service and sewerage, insulation, soundproofing, view, and room scale.

  • Based on the information framework and regulatory focus theory, this paper verifies the impact on the advertising effect when the matching effect forms between the video advertising content type (Information Type, Entertainment Type) and the information framework (Promotional, Prevention) and the regulatory focus (Promotion Orientation, Prevention Orientation) in social media. In order to verify, after selecting of the experimental subjects and finishing the prior investigation of the experimental operation, four video advertisements and formal experiments were performed. The experimental results showed that first, the content type affects the advertising effect of the video and the information framework; when the information video matches the preventive information framework, it will have a more obvious positive effect on the advertising effect; when the entertainment video matches the promotion information framework, it will have a more obvious positive effect on the advertising effect. Second, with the two matches of video content type and information framework, the entertainment-oriented video has a more obvious positive effect for the information-oriented video audience; the above results enrich user created content research and improve the quality and communication efficiency of video in social media.

  • The traditional typology of English poetic meters makes a binary division between strong-stress (or accentual) meters and accentual-syllabic (or syllable-stress or syllable-accent) meters. According to this typology, Old and Middle English alliterative poetry was composed in strong-stress meter; the iambic pentameter from Chaucer to Yeats and on to the present has been an accentual-syllabic meter. Intersecting with this literary typology is a linguistic typology that classifies languages of the world as stress-timed or syllable-timed or some mix of the two. English is a clear example of a stress-timed language. Whereas most descriptions of strong-stress meter focus on the counting of stresses, the present study focuses on the patterns of unstressed syllables between the stresses (possibly at isochronous intervals). The implications of this analysis suggest a new typology in which certain forms of English verse follow strict grammatical stress (mainly Old and Middle English, but for reasons different from “strong-stress” expectations) and other forms are shaped by a compromise of grammatical stress and the metrical template. Within this later group, iambic pentameter contrasts with trochaic, anapestic, and dipodic meters in lending itself more readily to modulation. Some of this modulation comes from an easy incorporation into iambic pentameter of elements associated with Old and Middle English meters.

  • Objectives: Spatial analysis is useful for understanding complicated causal relationships. This paper focuses trends and appling methods for spatial analysis associated with environmental asbestos exposure. Methods: Literature review and reflection of experience of authors were conducted to know academic background of spatial analysis, appling methods on epidemiology and asbestos exposure. Results: Spatial analysis based on spatial autocorrelation provides a variety of methods through which to conduct mapping, cluster analysis, diffusion, interpolation, and identification. Cause of disease occurrence can be investigated through spatial analysis. Appropriate methods can be applied according to contagiousness and continuity. Spatial analysis for asbestos exposure source is needed to study asbestos related diseases. Although a great amount of research has used spatial analysis to study exposure assessment and distribution of disease occurrence, these studies tend to focus on the construction of a thematic map without different forms of analysis. Recently, spatial analysis has been advanced by merging with web tools, mobile computing, statistical packages, social network analysis, and big data. Conclusions: Because the trend in spatial analysis has evolved from simple marking into a variety of forms of analyses, environmental researchers including asbestos exposure study are required to be aware of recent trends.

  • The purpose of this study is to analyze the differences by comparing consumption tendency of the Flatfish and Salmon using focus group interview (FGI). The FGI was conducted on university students in their 20s, with a total of 38 respondents surveyed in seven focus groups. Flatfish was recognized as a food in the form of popular sliced raw fish and had customer image that fit for middle-aged men in their 40s and 50s while eating with alcohol. 20s were perceived to be out of date with their age group as flatfish was considered old fish that did not match their age. In addition, they felt low accessibility to flatfish. Salmon was perceived by 20s as a food with a higher appeal than flatfish. Salmon has been creating a brand identity in their 20s and 30s for fashionable and trendy food that appealed to younger generations. They considered characteristics of salmon high in intangible value, such as something sophisticated, trendy, and beautiful. 20s consumed various forms of salmon including salmon sushi, salmon bowl, and salmon fillet, and they perceived it as a psychologically close food that can be easily accessible. In this study, the color of species (orange color of salmon), accessibility, restaurant image, and social media exposure were found to influence the consumption patterns of two species.

  • Depending on changes in industrial structure, industrial accident preventive measures have been developed in various forms. The focus for prevention of industrial accidents had been changed from part of the hardware to behavior and consciousness of workers. According to the change of focus, Korea's industrial accident preventive measures also has been adjusted to voluntary safety and health considering the safety culture and such attempts of preventive measures has contributed for reducing the accident rate. Safety culture is difficult to access due to the fact that factors that make up the safety culture are comprehensive and varied and there are many of external factors that affect to the safety culture. Moreover, there is a limit for applying specific preventive measures. Because, management culture or value of enterprises is various depending on each country or region. Nevertheless, looking at previous studies of advanced countries, they are presenting the fact that safety leadership has greater influence to formation of the safety culture. As a result, we study the Influence of manager's safety leadership that effect on safety culture. we want to propose the way to activate safety culture in workplace and to contribute for safety culture research.
