  • The accident risk at the construction workplace associated with agricultural engineering is comparatively higher than those of other fields due mainly to its complex work types and processes. Agricultural engineering deals with a variety of agricultural infrastructures from irrigation and drainage facilities to giant-scale coastal reclamation land infrastructures. The characteristics that most agricultural projects have conducted on a small-scale even worsen the situation drawing low attentions to risk management. Therefore, systematical risk assessment that focuses on details of agricultural construction work process is required in order to enhance safety management capacity and to prevent repetitive accidents ultimately. This study aims to categorize construction work types and processes of agricultural construction works, and to quantitatively assess the accident risk of them based on accident analysis. Regarding classification of construction works, actual 827 accident cases were thoroughly reviewed and coded by their construction site, facility and work type, project scale and so on. Most accidents (71.8 % of total cases) occurred in small-scale construction workplaces with less than 5 billion Korean won project budget. And those accidents related to agricultural infrastructure project (37.4%) and agricultural water development project (22.4%). In terms of work types, accidents frequently took place in form-work followed by pipe installation work, steel bar work and concrete work. The potential risks were compared with actual outbreak of accidents based on Analytic Hierarchy Process (AHP). The results show that the potential conditions of accident expected to be took place is somewhat different from the actual conditions where accidents actually happened. This implicates that risk management manuals or education needs to be adjusted by reflecting unexpected circumstances. Overall, this study is meaningful in that the results could be foundations as to strengthen risk management capacity for agricultural engineering projects.

  • This paper argues that nursing theories ideosyncratic to situations should be developed through research, if nursing practice is to be effective in achieving the objective of promoting, maintaining, or restoring health of clients / patients. After reviewing (1) the interactive relationship between the theory and research, (2) the type and sequence of research for theory- building, (3) the hierarchy of theories, and (4) congruence between the type of theory and research approach, it suggests (1) that more exploratory studies (research) should be undertaken as a way to develop descriptive theories that may lead to new hypotheses, (2) that more empirical studies should also be undertaken to test if new hypotheses generated from exploratory studies may be useful in the setting of nuring practice, (3) that more studies should be undertaken to develop useful measures of nursing concepts, and (4) that more replicated studies should be undertaken in order to give rise to the external validity of new theories. It also discusses the ethical considerations of nursing research in the future.

  • English absolutes and free adjuncts, despite their abridged syntactic forms, function as full subordinating adverbial clauses, with their semantic roles varied according to the interpretation of the matrix clauses. This paper investigates how to represent the syntactic structures and semantic variability of absolutes and free adjuncts in a unified way, accounting for overlapping properties among various subtypes of the constructions on the one hand, and differences on the other. In the proposed analysis, the clausal properties of absolutes and free adjuncts are captured by the subject selecting property and the clausal meaning associated with a predicative phrase, thus not calling for a null verb or complementizer. In classifying and defining diverse subtypes of the constructions via type constraints, the present work also provides an account of different uses of with involved in absolutes and free adjuncts.

  • It is essential to evaluate the blasting-enhanced permeability (BEP) feasibility of a low-permeability sandstone-type uranium deposit. In this work, the mineral composition, reservoir physical properties and rock mechanical properties of samples from sandstone-type uranium deposits were first measured. Then, the reformability evaluation method was established by the analytic hierarchy process-entropy weight method (AHP-EWM) and the fuzzy mathematics method. Finally, evaluation results were verified by the split Hopkinson Pressure Bar (SHPB) experiment and permeability test. Results show that medium sandstone, argillaceous sandstone and siltstone exhibit excellent reformability, followed by coarse sandstone and fine sandstone, while the reformability of sandy mudstone is poor and is not able to accept BEP reservoir stimulation. The permeability improvement and the distribution of damage fractures before and after the SHPB experiment confirm the correctness of evaluation results. This research provides a reformability evaluation method for the BEP of the low-permeability sandstone-type uranium deposit, which contributes to the selection of the appropriate regional and stratigraphic horizon of the BEP and the enhanced ISL of the low-permeability sandstone-type uranium deposit.

  • To evaluate the total quality activities is the most fundamental and critical process as one of the PDCA cycle. The quality award criteria such as Malcolm Baldrige National Quality Award and Deming Award can be a, pp.ied to the guideline for evaluating quality activities. We can identify several important factors for TQM by referring quality award criteria, but they don't suggest how efficiently implement TQM. In this paper, two methodologies are a, pp.ied to evaluate the TQM activities comparatively. One of them is the traditional scoring system (TSS) by analytic hierarchy process (AHP). TSS is the system which evaluates the performance of TQM by the weighted sum of critical success factors. Several quality award system are typical examples of TSS. The other is the efficiency measuring system (EMS) by data envelop analysis (DEA). DEA outperformed other alternative methods to measure the efficiency and it can be a, pp.ied to evaluate the TQM activities. The evaluation system by DEA can be named as EMS. The objective of this paper is to suggest a model called TAE (Total quality management Activities Evaluation), for evaluating TQM activities. In this model TQM organizations are classified into four types by considering TSS and EMS. Those types are high weighted sum and high efficiency type, high weighted sum and low efficiency type, low weighted sum and high efficiency type, and low weighted sum and low efficiency type. Therefore TQM organizations must not only make efforts to get the higher scores in terms of TSS, but also take necessary steps to enhance their efficiencies.

  • For the empirical analysis in this study, 335 cabin crews from large airline companies and budget airlines were interviewed using self-reporting questionnaires. The data was analyzed using the SPSS 23.0 and AMOS 23.0. First, of the organizational culture types, the relationship-oriented culture, hierarchy-oriented culture, and task-oriented culture were found to have negative impacts on job stress. Second, the innovation-oriented organizational culture, relationship-oriented culture, and hierarchy-oriented culture were found to have positive impacts on empowerment. Third, empowerment was found to have a negative impact on job stress. Fourth, as for the mediating effect of empowerment, the innovation-oriented culture, relationship-oriented culture, hierarchy-oriented culture, and task-oriented culture were verified to be all significantly mediated by empowerment in their relationship with job stress. As a result, it was shown that cabin crews of airline companies found their work more fun, interesting, and valuable in an organizational structure that was more oriented toward flexibility, rather than the hierarchical, task-oriented cultures that are more focused on control and order. It was also found that empowerment was a mediating factor in the relationship between organizational culture and job stress.

  • The card-based user interface is one of the easiest navigation methods for smart phones, and many of the contents have recently been exposed as cards. In this paper, we have dealt with the definitions of cards and the components of cards used in smart phones. The card can play multimedia including various images and media, and serves as an entry point into detailed contents through the arrangement of buttons or actions. The card UI had different characteristics depending on the type, if it could be classified into basic type, timeline type, workflow type, and dashboard type. The basic type and the timeline type were not suitable for the hierarchy and order of information, and they were suitable for providing large contents. The workflow type was not significantly different from the amount of content, horizontal content arrangement was possible, and the dashboard type was analyzed to be suitable for providing various data as graph or number.
