This study monitors the recent entrepreneurship and startup ecosystem to propose timely evidence-based policies for the activation of entrepreneurship focusing on innovative startups. The research questions mainly as follows: What is the status and environment of Korea"s innovative startups? What are the obstacles to establish innovative startups in Korea? The research was conducted at multi-level of national, firm, and individual levels. First, at the national level, using secondary data on 57 entrepreneurship components of 32 countries, international entrepreneurship index newly designed by STEPI have been compared with Korea. Particularly, in consideration of the distinct characteristics of Korea, weight factor adopts the components derived from Analytical Hierarchy Process (AHP) by experts. Second, at the firm level, this study carried out a comparative analysis focusing on recent global market trends and successful startup cases related to the 4th industrial revolution such as artificial intelligence, robotics, blockchain, and fintech. Third, at the individual level, this study conducted a survey and Focus Group Interview (FGI) with researchers of Government-Funded Research Institutes (GRI) in science and engineering field about the entrepreneurship and startup perception. As a result, total 10 major policy alternatives are derived by main issues and implications from each level. Firstly, at the national level, the results shows the necessity in 1) shifting the policy strategy from ‘Startup Pull’ to ‘Entrepreneurship Push’, 2) establishing entrepreneurial lifelong education system, 3) building the environment for technological finance. Secondly, at the firm level, it derivatively suggests policy alternatives in 1) restructuring the entry regulations in the new industry sectors from ‘Positive Listings’ to ‘Comprehensive Negative Listings’, 2) spreading entrepreneurship and startup culture through improvement of the system for attracting high-quality human resources into the innovative startups and expansion of social safety nets, 3) promoting the global successful startups like unicorns through building the private-led virtuous circle ecosystem of investment and exit. Lastly, at the individual level, it proposes policies in 1) supporting legal and institutional guidelines for researchers’ startups, 2) expanding organizations for supporting technology commercialization and innovative startups, 3) systematizing programs for supporting entrepreneurs from GRI, and 4) constructing the private supporting ecosystem for the researchers who want to establish startups. The results from the unique multi-level research are expected to provide multi-purpose solutions to various fields such as policy makers, startups, and researchers.

잠재술어는 미지값 문제를 논리적으로 형식화하기 위해 도입된 하나의 자료형으로서, 미지값의 의미를 대변하는 기술자이다. 본 논문에서는 ① 이 논리적 미지값 기술자를 도입함으로써, SLD[1] 도출(resolution)을 미지값을 포함하는 질의처리에 활용할 수 있다는 것과, ② 이러한 질의처리 방식이 정확하고 완벽하다는 것을 보인다. 본 연구는 SLD 도출이 이미 잘 구현되어 있는 강력한 추론 메카니즘이라는 점과 질의처리에서 정확하고 완벽함은 필수적인 요소라는 점에서 의미를 가진다. Implicit Predicate is a logically formulated descriptor for unknown values. Associated with unknown values, it expresses their semantics. The aims of this paper are ①to demonstrate that we can exploit SLD resolution to query evaluation due to the implicit predicate and, ② to show that our query evaluation is sound and complete. Our work has meaning in that SLD resolution is a powerful inferencing procedure already well developed and, soundness and completeness is one of the essential properties of query evaluation.

The regulations to reduce the exhaust emissions from vehicles are becoming increasingly stringent and encompassing more types of vehicles. In the case of heavy duty diesel engines, the Urea-SCR system is currently considered to reduce the NOx emission as a proved technology, and it is widely studied to get the high performance and durability. However, the injection nozzles occur some problems, including the nozzle clogging, deposition of urea-water solution on the inner wall of exhaust pipe. In this study, the effects of nozzle cap geometry, the length to diameter ratio(l<SUB>o</SUB>/d<SUB>o</SUB>) on the spray characteristics were investigated. The mean velocity, AMD and SMD distributions of the sprays were measured using a 2-D PDA system along the centerline and radial direction. As the experimental results, the higher length to diameter ratio(l<SUB>o</SUB>/d<SUB>o</SUB>) affects the increase of axial mean velocity and the decrease of radial mean velocity. The AMD and SMD increased with the length to diameter ratio(l<SUB>o</SUB>/d<SUB>o</SUB>), as well.

The purpose of this study is to comprehensively analyze the impact of science and technology on jobs, and to lay the foundation for future technological developments to lead to the creation of decent jobs. First of all, this paper analyzes the employment impact mechanisms of science and technology, focusing on recent literature analysis, and summarizes the stages and major types of technological development or innovation activities that affect the employment of firms. Second, we analyze key industry cases by type of corporate response strategy to the employment impact of technological development. - Cases focused on improving process efficiency due to digitalization: logistics industry - Examples of business model innovations, such as manufacturing services or entering new businesses: New Space - Collaboration between Humans and Machines: Changes in Healthcare Jobs Third, we analyze the effects of technological development in the domestic labor market and draw policy implications through the analysis of job changes in Korea centered on science and technology profession and the employment impact of corporate R&D investment. Lastly, by analyzing the current status and limitations of Korea’s fourth industrial revolution response policy, we draw implications for policy improvement direction, and suggest strategies and comprehensive policy plans to promote the creation of decent jobs through the development of science and technology.
