In this paper, profile error measurement method of a turbine blade using 3D-scanner is developed. The method begins with scanning the upper and lower sides of the blade on which three small balls are attached, and constructs a solid measurement model by registering the two scanned surfaces. Airfoils are derived from the model at each interval by intersecting it with a plane, and arranged with design airfoils. The 2² factorial design search method is engaged in arranging the two airfoils, from which the main blade parameters including the edge radius are computed. The developed measurement technique is applied to practical blade manufacturing and validates its effectiveness.

The purpose of this paper is to introduce the project specific scorecard for smart growth in the U.S. and find the implications for the development permit system in our country. The project specific scorecard is a tool that can help evaluate whether a particular development project is advancing the long-term viability of a community in the United States. So it could be also used to help a developer decide where the best location for a particular land use is, or to determine what land use is most appropriate over the long term for a particular land. In this context, the study analyzed the criteria of project specific scorecard and their application methods in three local governments in the U.S.; Austin, Maryland and New Jersey. Some policy implications are drawn through a case analysis. First, the evaluation factors for the use of project specific scorecard should be included; pre-screening, development location and contexts of plan. Second, project specific scorecard should be applied for the residential development project over 300,000m2 in non-urban area as political priority.

This study analyzed community characteristics affecting municipal expenditures. The paper explored the relations of the characteristics of 226 Korean municipalities to their expenditures for the period of years 2016-2017, the research developed multiple regression equations to examine the community characteristics affecting municipal expenditures. Six categories of community characteristics-‘city size’, ‘income’, ‘education’, ‘finance’, ‘employment’, and ‘infrastructure’-that were expandable to twenty-one community charcteristics are examined in this study. Three categories of municipal expanditures-‘total expanditure’, ‘expanditure for maintaince’, ‘expanditure for investment’- were based on functional expenditures. Additionally, 226 Korean municipalities were divided into the categories of the geographical location(the capital region, Gangwon region, Chungcheong region, Honam region, and Yeongnam region), administrative districts, of which included city, county, and borough and population size. As a result, this research found that financial condition’ and ‘support of centrual government’ of ‘finance variable’, ‘rate of beneficiary of national basic livelihood’ of ‘income’, ‘percentage of working force’ of ‘employment’ and ‘road length per person’ of ‘infrastructure’ had influenced the municipal expenditures.

The study explored the historical process of the formation and growth of Daeduck Valley using "the concept of technopolis wheel". "The technopolis wheel" includes six entities to compete and cooperate for technopolis development, such as research universities and research institutes, large corporations, small venture businesses, a central government, local governments, and support groups. Evaluating the role and networking of each entities, the paper found that Daeduck Valley has weaknesses in developing technopolis in terms of networks. Therefore, the paper suggested the direction and issues for development of linking mechanism between entities in Daeduck Valley.

This research explored the perforrnance of business incubators in Daejeon, Korea, specifically concentrating on the managers, tenants, and graduate companies of business incubators. This study reviewed the special characteristics of incubator managers, tenants and graduates and analyzed three specific measurements on the perforrnance of business incubators: 1) the contribution of tenant and graduate companies to the regional economy, 2) the quality and performance of the incubator’s different support services, and 3) the perforrnance of the support services for tenant and graduate companies taking root in Daejeon outside the incubator and the formation of networks within the community. As a basis for determining the performance of business incubators in Daejeon, data were compared between tenants and graduates, analyzing start-ups on both the linear and non-linear model, research and development innovation in start-ups as compared to that in corporations and in university and research institutes. Finally, this study suggested development strategies for business incubators in Daejeon, particularly in terrns of technology commercialization support for tenant and graduate companies.

The purpose of this study is to clarify the relationship between the factors of drinking/driving behavior and drunk driving. The tools include factors of drinking frequency, drinking quantity, frequency of excessive drinking, drinking quantity upon excessive drinking, drinking speed and drinking plans in order to measure the drinking behavior. As for the criterion for measuring the driving behavior, the criterion that had been delivered from Danne Parker’s DBQ and translated by Jeon-jin Park and others has been used. The frequency of drunk driving has been measured by being reported by the persons themselves on the number of drunk driving done for the last 6 months, and the habitual drunk drivers are defined as drivers who have drunk driving experiences of 6 times or more for the period of 6 months. Factorial analysis, correlation analysis, regression analysis, and T-test method have been used for data processing. As a result of the study, both the drinking behavior and the driving behavior turned out to be in positive relationship, and the drinking behavior rather than the driving behavior is identified to have more relevance to the drunk driving. Meanwhile, it has been revealed that while there is no difference in driving behavior between the habitual drunk drivers and the simple drunk drivers, there is difference in drinking behavior between them. In the last part, the control of drinking behavior as well as the role of the community for the prevention of drunk driving has been emphasized on the basis of the results of the study, and the future study project has been proposed.
