This study was conducted to evaluate the optimal operating condition of ultra-fine bubble washing machine for removing calcium chloride from road concrete structure. The diameter of the ultra-fine bubble was measured to 196.6 ± 100.6 nm and the ultra-fine bubble concentration was measured to 1.36 × 108 cell/ml. As a result of the performance on the spray device of the washing machine, it was confirmed that the washing efficiency of 93% and 91% appeared at 100cm and 150cm of injection distance at 100bar injection pressure. By increasing the ultra-fine bubble generation cycles from 2 to 6, the chloride removal rate increased from 1% to 7%. As the ultra-fine bubble generation air flow was lowered from 4 ml/min to 0.5 ml/min, it was confirmed that the washing efficiency increased up to 30%. The washing efficiency of ultra-fine bubble water was 25% higher than normal water.

The purpose of this research is to define the consulting competence of IT consultants and empirically analyze the perceptual differences between the IT consultant group and the client group. Based on the previous researches and the opinion of the actual IT consultants, the consulting capability model has been established, which consists of six categories and eighteen factors. Six categories are (1) IT domain expertise, (2) problem solving ability, (3) project management capability, (4) communication skills, (5) human relations skills, and (6) professional ethics and attitude. Two field surveys have been performed and the responses of 174 IT consultants 116 clients have been acquired. It is shown that the level of possessed proficiency of IT consulting capability is far lower than the level of the required proficiency. And there exist the perceptual difference between two responding groups with respect to the level required proficiency but no difference exists in terms of the level of possessed proficiency. The findings of this research can provide some useful information in order to fully understand the differences between the IT consultant group and the client group.

Consulting effects of enterprise management are paying off and growing in the country as well as worldwide. Consulting, the academic research foundation of the consulting classification is narrow and, therefore, the job satisfaction of the involved consultants has not been studied sufficiently. Although there were not enough references, I recognized that consulting industry would have a huge effects on business, I tried to draw the concept of the satisfaction of job performance of consultants in the point of the growth of industry itself, and I studied the correlation between consultant satisfaction and performance. It means, on the causes of consulting performance, the previous studies were quantitatively limited, but this study represents the new perspective and another way of thinking. As a result, this study showed that the performance is affected by the job satisfaction of consultants. Second, it showed that social support on consultants and consulting performance are highly related. Further more, a following-up study can use it to strengthen consulting capabilities such as, self development of consultants, how to make reasonable consulting payments, how to develop and how to establish direction of support policies for consulting. It is possible that this study can be policy data when policy to strengthen industrial competitiveness can be made on the basis of consulting.
