Despite the increasing adoption of gamification and its huge potential in tourism, research in gamification is still limited. As preliminary findings show that the effectiveness of gamification depends on the context of its application and the players' use of the gamified app, this paper fills in these gaps: by exploring and analysing the application of gamification in a specific e-commerce tourism context; and assessing the gamification's effectiveness by measuring the players' gamification usage and the latter's behavioural and psychological outcomes. The gamified TripAdvisor website and its Facebook enabled gamification app are used as the specific context of the study. Findings from a survey conducted on TripAdvisor users provide useful practical and theoretical implications to gamification designers and researchers alike on how game mechanics can be designed for enhancing the users' motivation, flow, task involvement and engagement with the 'play' tasks, and so, increasing the gamification's effectiveness.

Effective internal communication is known to have a positive impact on business performance, but there is a lack of research on the effects of online channels for workplace communication. This study using regression analysis examines how task-technology fit, information richness, self-efficacy, perceived ease of use, and perceived usefulness related to online communication channels affect not only the satisfaction with the tools but also the effectiveness of them. Additionally, we verify how the organizational culture of online and offline communication shows the control effect. As a result, all five variables were positively correlated with internal communication channels satisfaction, and we found that the organizational culture of online and offline communication controls the relationship between online communication channels satisfaction and effectiveness.

The purpose of this study is to compare and analyze the effect of the length and volume fraction of smooth steel fiber on the electrical conductivity and shielding effectiveness of cementitious composites. As the length and volume fraction of the fiber increase, the movement of electrons becomes active and the formation of a conductive path becomes advantageous, thereby increasing electrical conductivity. Accordingly, the electrical conductivity and the shielding effectiveness showed a very close relationship. Thereafter, it is judged that research is needed to increase the shielding effect.

At present, the importance of organizational effectiveness is highlighted even more as business environment enters into a new type of work setting, the smartwork environment. This new type of work environment could be significantly influential in promoting organizational effectiveness of office administrators who carry out atypical types of tasks in general and are exposed to emotional labor excessively. Organizational effectiveness of office administrators could also be controlled by their concerns at work, their personal values and the increasing demand for work-life balance. The main purpose of this research is to investigate how smartwork environment perceived by office administrators is related with organizational effectiveness. In addition, this research places the focus on how concerns and work-life balance moderate the relationship between smartwork environment and organizational effectiveness. The survey was conducted among 102 office administrators, and data were analyzed by moderated multiple regression analysis method. Job autonomy of smartwork environment showed positive effect on job satisfaction, organizational commitment, and innovative behavior. IT dependence of smartwork environment showed negative effect on job satisfaction and organizational commitment and positive effect innovative behavior. It was found that concerns with impact positively moderate the effects of job autonomy on job satisfaction and innovative behavior; concerns with self negatively moderate the effects of job autonomy on organizational commitment and innovative behavior. Also, it was found that work-life balance moderates the effects of job autonomy on organizational commitment and the effects of IT dependence on innovative behavior. The result of this research can be taken into consideration when a strategic human resource development plan is prepared for office administrators in smartwork environment.

This study attempts to examine standards on the effectiveness of the rights to social security of people with disability. The current research makes the standards on effectiveness of social security rights to the disabled. This standards draw four right areas and five general principles from debates about effectiveness of general social security rights and extend for applying three social area to the disabled. Four right areas are benefit coverage, benefit structure, benefit restriction and rights relief. Five general principles are enforceable rule principle, national finance principle, unconditional principle, adequacy principle and penalties principle. These four right areas and five general principles apply to three social security areas of income support, employment security and medical security. Measurement values are 'high' and 'low'. These measurement values divided into two that are used to ensure same intervals. This study on standards to the effectiveness of the rights to social security of people with disability has political and theoretical implications. First, in political aspects, these standards provide objective understanding of the present level of social security policies for the disabled. Second, theoretically the current study expands debates about the effectiveness of general social security through multi-disciplined research. At once this study is significant to establish empirical research foundation.

Seasonal frozen ground affects structural behavior in South Korea. Frost and heaving of seasonal frozen ground results in the critical damage of roadway, railroad, and buried pipeline. It has been widely used to substitute frost susceptible soils with granular soils. This paper presents experimental investigation on the effectiveness of soil-shredded tire and soil-expanded polystylene (EPS) mixtures to reduce frost depth and force around a buried pipeline. Experimental data such as measured temperature profile and the deformation of buried pipeline were carefully observed and provide the evidence of the effectiveness of soil mixtures.

Internal replaceable electronic module substitutions can impact EMC (ElectroMagnetic Compatibility) qualification testing and results if EMC testing is conducted at the cabinet level. The impact of component substitutions on EMC qualification results therefore should be evaluated. If a qualitative evaluation is not adequate to ensure that the modified product will not impact the cabinet level EMC qualification results, a new qualification testing should be conducted. Component level retesting should be conducted under electromagnetically equivalent conditions with the cabinet level test. This paper analyzes the propagation of conducted susceptibility test waveforms in a representative cabinet and evaluates the impact of component substitutions on cabinet level EMC qualification results according to the location of the replacement items. A guideline for a qualitative evaluation of the impact of component substitutions is described based on the propagation of the conducted susceptibility test waveforms. A module level test method is also described based on an analysis of the shielding effectiveness of the cabinet.
