Medical institutions are abundant in human resources and have a unique structure with diverse professions and various organizational cultures coexist. This organizational culture influences organizational effectiveness and influences the effectiveness of the organization as a factor of leadership and organizational culture. Leadership is an important factor in linking employee behavior to organizational commitment to achieve job satisfaction. The purpose of this study was to analyze the effect of organizational effectiveness on organizational culture, leadership perception, and job stress in a special organization called radiologist. As a result, organizational culture and transformational leadership showed high correlation with 0.627. Among the organizational effectiveness variables, organizational commitment showed the highest influence with transformational leadership(${\beta}=0.284$, p<0.001), and job satisfaction was also the highest with transformational leadership (${\beta}=0.440$, p<0.001). The results showed that the expectation of transformational leadership affects organizational commitment and job satisfaction. In order to expect a positive change in the effectiveness of the organization, the radiologist culture requires an organizational culture that can fully demonstrate autonomy and creativity, and transformational leadership is required for this.

Roof greening recently emerged to be an important issue of environmental policies in a city. To cover roofs of buildings with green vegetation gives chances not only to improve urban environmental function but also provides the opportunities of environmental learning and convenience for users in the building. This study aimed to give directions for roof greening plan to designers by acknowledging the relationships between ecological and utilizational effectiveness. 10 sites and 15 variables were adopted to measure the relationships. As a result, no positive correlations was found between them. One of the results in correlation analysis among variables, however, showed that the roof gardens have high utilizational effectiveness only when a green roof was made by focusing on ecological functions in addition to the concepts that will guarantee user's convenience such as accessibility, entrance and exit, facilities for convenience and learning. The results implies that a green roof has to be designed considering multi-functional effects. Correlation between species of vegetation and the number of daily users, average staying hours, and attending level for environment educational programs were not significant. These findings imply that when a green roof has to be take high utilizational effectiveness, both plentiful vegetation species and design concepts for users' convenience are should be considered.

With the rapid growth in the use of digital advertising media among consumers, there is an increasing interest in the utilization of virtual advertising and PPL as an alternative to traditional television advertising. Nonetheless, few studies have compared the effects of these new advertising platforms, still lacking knowledge on their relative effects for maximizing advertising effectiveness. This study, thus, intends to compare virtual advertising and PPL with respect to advertising effectiveness (i.e., consumer evaluations of advertising attributes, brand attitudes, and purchase intentions), controlling for the level of product involvement. An experiment was conducted with a sample of 360 participants and actual ads were used as test stimuli. According to the results, consumers exhibit more favorable evaluations on all the three advertising attributes (i.e., entertainment, informativeness, and irritation) for high-involvement products, whereas, for low-involvement products, virtual advertising is perceived to be more irritating than PPL. In particular, the effect of informational value of virtual advertising on brand attitudes was found to be most significant. In addition, for high-involvement products, virtual advertised products. Advertising practitioners may have to consider these results and fully utilize the advantages of virtual advertising and PPL in order to achieve maximum advertising effectiveness.

A steel high-rise building (HRB) with 15 stories was analyzed under the dynamic load of wind or four different earthquakes taking into consideration the effect of soil-structure interaction (SSI) and using tuned mass damper (TMD) devices to resist these types of dynamic loads. The behavior of the steel HRB as a lightweight structure subjected to dynamic loads is critical especially for wind load with effect maximum at the top of the building and reduced until the base of the building, while on the contrary for seismic load with effect maximum at the base and reduced until the top of the building. The TMDs as a successful passive resistance method against the effect of wind or earthquakes is used to mitigate their effects on the steel high-rise building. Lateral displacements, top accelerations and straining actions were computed to judge the effectiveness of the TMDs on the response of the steel HRB subjected to wind or earthquakes.

Quality of the power system depends upon the reliability of its components such as transformer, transmission lines, insulators, circuit breakers and isolators. The transient voltage due to internal or external reasons may affect the insulation level of the components. The insulation level of these components must be tested against these conditions. Different studies, testing of different electrical components against high voltage impulses and different industrial applications rely on the international manufactures for pulsed power generation and testing, that is quite expensive and large in size. In this paper a model of impulse voltage generator with capacitive load of pin type insulator is studied by simulation method and by an experimental setup. A ten stage high voltage impulse generator (HVIG) is designed and implemented for different applications. In this proposed model, the cost has been reduced by using small and cheap capacitors as an alternative for large and expensive ones while achieving the same effectiveness. Effect of the distributed capacitance in each stage is analyzed to prove the effectiveness of the model. Different values of front and tail resistances have been used to get IEC standard waveforms. Results reveal the effectiveness at reduced cost of the proposed model.

To development of the low toxic preservatives, we prepared 29 kinds of chemicals using dinotefuran of low toxic insecticide, IPBC and propiconazol of fungicide, and clove oil has fungicidal activity, but is harmless to humans. It was conducted to investigate the inhibitory effectiveness of mycelial growth and anti-mold effectiveness to treated PDA medium and wood specimen with prepared chemicals. It was not showed anti-mold effectiveness that solvent and emulsifier form preservatives. Therefor, we thought that only four component, dinotefuran, IPBC, propiconazol and clove oil, has anti-mold effectiveness. In the PDA medium test, the preservative which has much IPBC showed high anti-mold effectiveness. By the wood specimen test, it was known that many prepared preservatives which showed good inhibitory effectiveness of mycelial growth in the PDA medium test, have not anti-mold effectiveness. Of all prepared preservatives in this study, only three preservatives containing dinotefuran and IPBC, or adding clove oil appeared the excellent anti-mold effectiveness.
