A Case Study of Characteristics of Damages Caused by Typhoon EWINIAR 2006 in South Korea

During recent years, the climate of Korea has clearly been divided between dry season and rainy season due to the global warming and other reasons, and a record breaking rain is falling every year. The mountain slopes in Korea receives significant damage generally during the seasons of high rain front and typhoon. In 2006, the rainy season started in July and Typhoon EWINIAR which hit South Korea between July 26 and 28 caused significant damage to various slopes and roads. This paper presents a case study of the damages and characteristics of the damages to cut slopes, fill slopes, and roads caused by the concentrated heavy rains for 3 days in the regions of Inje and YangYang

A New Paradigm Unifying the Concepts in Particle Abrasion and Breakage

This study introduces a new paradigm that unifies abrasion and breakage concepts, allowing for a holistic understanding of the comminution process. The significance of this paradigm lies in its ability to present both abrasion and breakage in a single big picture because both processes can co-occur under loading as particles are subjected to friction as well as collision. A comprehensive descriptive framework is employed to this end, which operates in a log-transformed surface-area-to-volume ratio ($A/V$) and volume ($V$) space. This space facilitates a holistic characterization of the four-dimensional particle geometry features, i.e., volume ($V$), surface area ($A$), size ($D$), and shape (${\beta}$). Consequently, this approach enables to systematically relate the co-occurring abrasion and breakage process to co-evolving particle shape and size. Transformative concepts including the breakage line, sphere line, and average shape-conserving line are introduced to describe the limit states and a special comminution process. This approach also uncovers a self-similar nature in evolving particle geometry during comminution, which will be a significant discovery for the granular materials research community given the most fundamental properties observed in natural phenomena.Comment: 10 pages, 5 figures; No difference from arXiv:2306.04635v1 except the first page stam

The Impact Of Job Demands And Resources On Job Crafting

Organizations are constantly under pressure for survival in the current highly volatile work environment. This change has been accelerated by trends such as smart work environments and artificial intelligence in the organizational context. Given such uncertainty deriving from a fast rate of change and high complexity, it is vital for organizations to fully utilize and support individuals to be fully engaged in their work, setting grounds for transformation and modification of general roles and specific tasks. Based on the job demands-resources model, our hypotheses are tested using empirical data extracted from 172 subjects currently working in organizations. By commissioning a questionnaire survey method and hierarchical regression analysis, the results offer partially strong support for our proposed research model. We attained moderate support for our hypotheses, in that an individuals’ perception of job resources and job demands in the work context induce job crafting (i.e., task, cognitive, and relational), which acts as a critical mechanism arousing individual work engagement and job stress. In general, job resources (i.e., job autonomy and performance feedback) predicted work engagement, while job demands (i.e., work overload, emotional demands, and technology demands) affected job stress. Also, job demands and job resources both influenced task job crafting, while emotional demands were related to cognitive and relational job crafting, implying different paths between demands and resources and various job crafting activities. In addition, three job crafting dimensions affected work engagement, while only relational job crafting positively affected job stress.

Reducing the color shift of a multidomain vertical alignment liquid crystal display using dual threshold voltages

A multidomain vertical alignment liquid crystal display (MVA LCD) with reduced color shift is proposed. Each pixel is divided into a main region and a subregion. A thin electric shielding layer is embedded in the subregion to generate a higher threshold voltage than that of the main region. As a result, the final gamma curve is a superposition of two different-shaped gamma curves. Such a MVA LCD exhibits a reduced color shift while only requires a single thin-film transistor. Its potential application for LCD TVs is emphasized. (C) 2008 American Institute of Physics
