This research aims to investigate how major cities in Korea utilize smart city-related technologies, develop key performance indicators (KPIs) to measure the smartness and efficiency of cities, and propose a methodology for assessing and suggesting smart city policy directions based on Data Envelopment Analysis (DEA). Referring to the CITYkeys Smart City Performance Measurement Framework, 10 key performance indicators (KPIs) were derived. For each KPI, city statistical data were allocated to input and output variables, and 15 cities were assigned as Decision Making Units (DMUs). The DEA methodology was employed to evaluate the operational efficiency and scale profitability of cities, providing insights into the operational efficiency of each city. Finally, the operational efficiency among DMUs was ranked to propose smart city policy directions for each city.

While creativity and innovation is the key to drive the creative economy in the South Korea, the development of analysis framework to evaluate the size and performance is limited. The present study suggests a framework and a method to assess economic impact of the creative economy using inter-industry analysis which employs input-output efficiencies populated by the Korean Bank and empirical data from the national informatization survey conducted by the National Information-society Agency(NIA). The results indicated that, as of 2013, despite of economy downturn, the creative innovation based on the information communication technology(ICT) had been significantly led the production, value-added, and employment inducement. The effect is predominant in the creative industry in an broad sense, that is, technology intensive manufacturing industry. Theoretical and policy implications are discussed.

In order to provide technical financial support to small and medium-sized venture companies based on technology, the government implemented the TCB evaluation, which is a kind of technology rating evaluation, from the Kibo and a qualified private TCB. In this paper, we briefly review the current state of TCB evaluation and available indicators related to technology evaluation accumulated in the Korea Credit Information Services (TDB), and then use indicators that have a significant effect on the technology rating score. Multiple regression techniques will be explored. And the relative importance and classification accuracy of the indicators were calculated by applying the key indicators as independent features applied to the generalized boosting model, which is a representative machine learning classifier, as the class influence and the fitness of each model. As a result of the analysis, it was analyzed that the relative importance between the two models was not significantly different. However, GBM model had more weight on the InnoBiz certification, R&D department, patent registration and venture confirmation indicators than regression model.

Meta-evaluation for national R&D programs should be established within the framework of whole R&D system linked with science and technology needs and objectives. The R&D program evaluation system can be understood as a circulation of input, implementation, output, and utilization. In the result of the Delphi survey, which consisted of twenty-four experts (performed in three rounds), twenty-four indices were developed. The meta-evaluation model included sub-items which were important points of view of it as follow (eight items): propriety of planning, sufficiency of information, and propriety of evaluators in evaluation input; appropriateness of method and appropriateness of procedure in evaluation implementation; credibility of output in evaluation output; and usefulness of report and application of evaluation utilization. As the application of the meta-evaluation model, the total mean was lower than 3.0 of the median value of 2.73 (5 point Likert scale). Finally, it was suggested that the feedback of evaluation results should be more enforced to R&D program improvement particularly (evaluation utilization 2.50).

Studies have shown that research and development has positively impacted the upbringing of construction industry. However, its economic effect has not yet been fully investigated. This study develops an economic effect analysis model for R&D performance. In-depth interview and review of the literature produced a total of 11 performance indicators that considered the public characteristics of construction industry. A case study which involved the Expressway & Transportation Research Institute was conducted in order to verify the proposed model. The result showed that the return on investment of the institute was 3.3 times of the R&D investment. The proposed model is expected to help researchers analyze an economic effect analysis model for R&D performance.

Productivity is important to evaluate an efficiency of performed work and organization in construction industry. The productivity should be defined as activity level rather than macro level in order to effectively use productivity data and manage a project. The primary objective of this study is to develop a construction productivity management system using data warehouse, OLAP and data mining technologies which enables to easily accumulate the construction productivity data and perform multi layer analysis. Finally, it is anticipated that the effective use of the developed system would be able to measure the result of project and make a plan of the similar project with reliability.

학습 프로세스는 학습참여자인 학습자들과 교수자의 상호적인 활동에 의하여 교수-학습이 이루어지는 과정이라고 할 수 있다. 이러한 과정에서 일련의 학습자료들이 제공되고 만들어진다. 교수-학습이론에서 여러 가지 모델이 제안되어 이용되고 있지만 각 학습참여자의 역할과 학습자료간의 관계가 명시적으로 정의되어 운영되지 못하는 점이 있다. 한편 서비스제공이나 소프트웨어개발과 같은 추상적인 결과물을 생산해야하는 경영학이나 소프트웨어공학에서는 프로세스(과정)의 관리만이 그 결과물의 질을 담보할 수 있다고 생각한다. 결과물의 질관리를 위한 프로세스의 관리는 프로세스의 역할별 활동에 의한 투입/산출물, 프로세스들의 관계를 명시하고, 그에 따른 측정가능한 지표를 개발-분석함으로써 이루어진다. 본 논문에서는 소프트웨어 개발 방법론에 기반하여 구성주의적 교수-학습 프로세스를 정의함으로써 교수활동에 구성주의적 교수-학습이론을 용이하게 적용할 수 있는 지침을 제공하고, 향후 프로세스를 기반으로 하는 교육 서비스사이언스의 기본적 구성요소를 제공하고자 한다.
