  • In this paper, we present the FlappyBird Competition System (FCS) implementation, a competition-based automated assessment system used in an entry-level artificial intelligence (AI) course at a university. The proposed system provides an evaluation method suitable for AI courses while taking advantage of automated assessment methods. Students are to design a neural network structure, train the weights, and tune hyperparameters using the given reinforcement learning code to improve the overall performance of game AI. Students participate using the resulting trained model during the competition, and the system automatically calculates the final score based on the ranking. The user evaluation conducted after the semester ends shows that our competition-based automated assessment system promotes active participation and inspires students to be interested and motivated to learn AI. Using FCS, the instructor significantly reduces the amount of time required for assessment.

  • 본고에서는 통신시장의 구조를 최대한 반영하면서 투명성, 객관성, 규제 비용, 정책목표 구현 등을 고려한 평가체계를 개발하여, 기존 평가 방법 대비 개선된 새로운 평가 기준을 만들었다. 그리고 국내 이동통신시장에 대해 새로운 평가기준을 적용하여 경쟁상황 평가를 시도하였다. 경쟁상황에 대한 1차 판단 결과 국내 이동통신시장은 지배적 사업자로의 지속적인 쏠림현상이 존재하여 유효경쟁 상태에 있지 않은 것으로 나타났다.

  • State highway agencies (SHAs) typically apply a competitive procurement procedure to select contractors for their design-bid-build projects. Since the level of competition affects construction bid prices and project outcomes, the Federal Highway Agency (FHWA) suggests SHAs seek ways to improve competition among contractors continuously. However, they rarely conduct an empirical assessment of the current competition level necessary to identify room for improvement. Besides the number of bidders on a project, other factors such as winning or losing rates among the contractors in previous projects can also indicate the degree of competition; only a few contractors may have won the majority of the projects in a specific region. However, few studies have investigated such factors. This paper proposes a network analysis-based approach to evaluating contractor competition levels of highway projects using historical bid tabulation data. The proposed method provides insights into overall competition levels, the determination of competitive contractors, and winning rate distribution among contractors.

  • 본 논문은 '경쟁제고'와 '반사실'의 두 가지 핵심 개념을 중심으로 경쟁제한적 기업결합 심사에서 항변으로 고려되는 효율성 및 파산기업 문제의 경제적 근거와 인정 요건들을 정합적으로 설명한다. 효율성 항변에 대해서는 그 경제적 근거가 효율성 증대 자체보다 효율성 증대가 초래하는 경쟁제고 효과에 있음을 강조한다. 파산기업 항변에 대해서는 당해 기업결합이 진행된 후의 경쟁 상황이 그렇지 않은 반사실 경우의 그것과 크게 다르지 않다는 점이 주요 경제적 근거라고 설명한다. 이러한 이해 방식은 최근의 관련 국제 논의 및 경쟁법 선진국들이 운용하고 있는 기업결합 가이드라인에 공통으로 나타나고 있는 것이다. 이러한 이해를 바탕으로 할 경우 항변의 인정 요건들도 정합적으로 설명된다. 또한, 본 논문에서는 이러한 이해를 바탕으로 그 간의 국내 기업결합 심사 사례들에 대한 분석을 통해 우리나라 "기업결합심사기준"에 대한 개선 방향을 제시한다. 효율성과 관련해서는 소비자 이전 가능성 요건 합병 특유성 인정 요건으로서의 제3자와의 기업결합 문제 등을 논의하며, 파산기업과 관련해서 경제적 근거 포함 문제 등을 논의한다.

  • The paper focuses on a type of mathematics competence noted as synthetic. It is needed for success in multiple choice competition problems and it is crucial for the further development of advanced school students. The concept of synthetic competence includes a large fraction of mathematical competences, but also competences and skills related to informatics and linguistics. The general structure of a multiple choice competition is considered as the first level of assessment of the mathematics component of the synthetic competence. As the second level under consideration is the set of complex tasks in a competition test any of which is a bouquet of ideas. Our standpoint on the didactic specifics and goals of the two levels in perspective of the gifted education is briefly presented in the article and some examples are given.

  • Purpose - This paper empirically investigates the competition effect of exports between Korea and China in their common-export markets considering market sophistication. Modern market sophistication includes an importing country's aggregate demand for products of high quality, design, novelty, eco-friendliness, and even IPR protection. Using an empirical analysis to identify the demand for product quality across countries, this paper estimates the effects of market sophistication on the competition between Korean exports and Chinese products. Design/Methodology - Our empirical model considers the relationship between an importing country's consumer sophistication and the export competition between Korea and China. This study employs the existing theoretical framework to identify the aggregate demand for product quality across countries. Using a quite direct measurement (the consumer sophistication index, our analysis investigates the differential effects of Korea's export market sophistication, particularly in markets where Korean exports are in competition with similar Chinese products. Findings - Our main findings can be summarized as follows: the negative effects of the export competition between Korea and China on Korea's exports are stronger in third markets where consumers are less sophisticated while the effects are not as pronounced in markets where consumers are more sophisticated. This result, however, best applies to differentiated goods which significantly vary in product quality. Originality/value - Existing studies focus on the supply side of production and make the assumption that the market preference for export quality is identical across countries. This paper attempts to evaluate the export competition between Korea and China from the demand-side perspective. This area of trade studies is underexplored both empirically and in theory, although the issue has long been important to Korean and world trade.

  • 이 글에서는 먼저 경쟁과 다양성이 미디어 정책의 구체적인 수단을 규정한 방송관련법이 추구하는 주된 목적이 된다는 것을 전제로 하여 각각의 개념과 구성요소 그리고 그 제도적 구현의 모습을 살펴보고, 특정분야의 경쟁법으로서의 방송관련법에서는 경쟁 목적이 차별성 요인을 갖는 한편 다양성 가치도 특수성을 갖는다는 논의를 전개한다. 다음으로 경쟁과 다양성 가치를 조화롭게 실현하기 위해서는 방송시장 특유의 구조적 규제수단을 포함하는 특별한 경쟁규칙이 필요하다고 전제하면서, 방송관련법상 경쟁 목적 규제와 다양성 목적 규제에 대하여 개선되어야 할 방향을 다음과 같이 제시한다. 첫째, 경쟁 목적 규제의 개선 방안이다. 사전적인 상태적 규제로서의 시청점유율 규제와 사후적인 행위규제로서의 금지행위 규제는 다양성 가치를 추구하면서도 원인적 규제를 대체하는 데 중요한 역할을 할 수 있다. 이를 위하여 공정거래법의 위법성 판단방식을 유추하여 다양성 관련 요소를 금지행위의 위법성 판단기준의 고려요소로 하는 방식을 구체적으로 개발할 필요가 있다. 둘째, 다양성 목적 규제의 개선 방안이다. 이는 규제 목적의 설정, 대체가능한 규제수단의 식별, 규제 목적에 맞는 규제수단과 규제수준의 선택이라는 3가지 관점에서 검토될 수 있다. 이러한 관점에서 다양성 가치가 단순한 수사적 도구에 그치지 않고 평가 및 분석 도구로 사용될 수 있는 제도적 수단 위주로 규제 틀을 개선하는 한편, 경쟁과 같은 경제적 목적과의 조화를 고려할 때 불합리해 보이는 규제에 대하여는 이를 유지할 것인가 또는 어느 정도로 유지할 것인가를 신중하게 재검토해야 한다.

  • Purpose - Investors, creditors, governments, and others make decisions using reasonable information provided by others. In many cases, the users of this information have goals and objectives conflicting with those of the information's producers, indicating the need for external auditors. Research design, data, and methodology - Competition in auditing has noticeably intensified globally, especially in developed countries. This means that auditors are striving to increase the efficiency of their methods. In recent years, risk-based auditing has become prominent among these efforts. In risk-assessment auditing, the auditor may directly affect the effectiveness and efficiency of the audit. Results - As a central framework, the risk assessment process improves audit quality and effectiveness such that the audit will lead to necessary changes. Previous studies have shown that risk assessment affects the nature, timing, and content of audit procedures. Conclusions - In the planning stage of an audit, audit risk assessment may identify any inappropriate or inefficient distribution of resources or determine whether the results of an audit will be ineffective or incorrect. Thus, assessing audit risk is a critical task.

  • Under circumstances with increasing uncertainty, strategic flexibility has become an essential point on which my R&D management system should be based. Unfortunately the present R&D management system for government sponsored R&D programs cannot be said to be so flexible to adapt appropriately to various threatens such as technological failure, a severe change in competition environment, and so on. In this paper a new scheme for R&D planning and economic assessment with strategic flexibility is suggested and applied to a real R&D program. In the newly suggested R&D management system, economic valuation based on real option theory is performed for various alternative scenarios which have different strategic scheme for R&D process each and the result of the assessment is fed back to R&D planning to choose more superior strategic scheme. Introducing strategic flexibility into R&D planning and economic assessment, the value of R&D project could be remarkably enhanced.
