  • 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.

  • I focused my attentation on two points in this paper. Firstly, I explore the relationships between the competition system and the philosophical bases in economic and social doctrines which encouraged, the architectural profession which it supported. Secondly, I intend to describe the development of the modern competition system. The economic theories were applied to architecture; these were natural laws and laissez-faire. The principles of competition and progress were never doubted. Two developments aided architects in attaining both a sense of professional identity and a way of regulating the comprtition system; these were the founding of professional societies and the emergence of a professional architectural press. The first organized effort to control the competition system was made in 1839 by the Competition Committee of the Institute of British Architects, but the problems had remained virtually unchanged by the 1880s. A code of regulations was drawn up by the RIBA in 1872, but this were much like earlier codes and recommendations. From the 1890s, the RIBA established a permanent committee to review the conditions of all competitions and authorize members to participate; the measure was paralleled in various other countries, notably in the 1911 international regulations of the CIAM.

  • The paper examines the role of the informal sector on innovation activities of urban formal manufacturing enterprises in India. It provides empirical evidence on firm-level linkages between formal and informal sectors by using the World Bank Enterprise Survey, 2013-14 and the Innovation Follow-up survey, 2014. Primarily, the paper aims to examine the effect of informal sector competition on innovation in urban formal manufacturing enterprises in India. Secondly, the paper analyses the mediation effect of informal sector competition on innovations in the urban manufacturing enterprises. It determines the direct and indirect influence of business regulations and constraints on innovation outcomes through the mediation effect of informal sector competition by using the SEM "Structural Equation Modeling" guidelines. The econometric results show that informal sector competition has a negative effect on the introduction of product innovations while industry-level informal sector competition has a positive effect on product innovation through the local knowledge spillovers from the informal to the formal sector. However, the informal sector competition was found to have no significant effect on the probability of introducing process innovations. Further, the results show the inhibitive role of informal sector competition on innovation in urban formal manufacturing enterprises is more severe for firms with heavy regulatory burdens and is relatively weakened in firms with resource constraints. This suggests that the informal sector plays an important role in the NIS (National Innovation System) in India.

  • A type of delayed Lotka-Volterra competition reaction-diffusion system is considered. By constructing a new Lyapunov function, we prove that the unique positive steady-state solution is globally asymptotically stable when interspecies competition is weaker than intraspecies competition. Moreover, we show that the stability property does not depend on the diffusion coefficients and time delays.

  • In this paper, we consider two-species periodic Gilpin-Ayala competition system with delay and impulsive effect. By using some analysis methods, sufficient conditions for the permanence of the system are derived. Further, we give the conditions of the existence and global asymptotic stable of positive periodic solution.

  • The purpose of this study is to assess the state of competition in Nepalese banking over the period from 2010 to 2019. This study employs panel data and a non-structural Panzar-Rosse model to measure the degree of competition in the Nepalese banking industry. The first reduced-form equation is applied to gauge competition, and the second model is used to test the long-run equilibrium in the banking market. The finding reveals that the Nepalese banking market is equilibrium in the long-run. It implies that the factor prices do not affect ROA in the long-run. The result of the H-statistic shows that the Nepalese banking system is operating under the state of perfect competition and is shifted from monopolistic competition to perfect competition. The reduced-form model reveals that the interest income is positive and significantly affected by factor prices. Similarly, the macroeconomic variable GDP growth is positively related to interest income. On the contrary, the bank's specific factors risk and the number of bank branches are inversely associated with the regressand. The outcomes of the study may be advantageous to the policymakers, especially to Nepal Rastra Bank to implement monetary policy and M&A policy for the stability and growth of the financial system of Nepal.

  • This paper aims to analyze hegemonic competition and the role of naval power. To this end the paper is composed of four chapters titled introduction, the role of naval power in the hegemonic competition, the role of naval power in the East Asia, and the lessons and implications for the Korean Peninsula. Since the modern era, the hegemonic competition in the East Asian region has been the intrusion and struggle process between the world system and the East Asian regional system, and the ocean between these two systems has become the goal and means of supremacy(hegemony). Currently, the hegemonic competition between the US and China consists of systemic competition at the global level and marine competition at the regional level. When South Korea is forced to make strategic choices in the course of the US-China hegemonic competition, naval power will be the first factor to be considered. The ROK is asymmetrically maintaining a deep dependency relationship with the United States in terms of security and China in relation to the economy. And while the ROK's national economic power is acquired from the ocean, the ROK's military power is imbalanced because it is centered on the ground forces. These international relations and asymmetric-unbalanced resources distribution will not be able to effectively cope with the hegemonic competition between the US and China in the future, and will limit Korea's strategic choice. Since naval power and forces are the prerequisites for the hegemonic competition or the maintenance of supremacy we must construct balanced naval forces(naval power) that are not subordinate to the ground forces at the national strategic level for the future of the country.

  • 민간 시장에서의 경쟁의 실패는 일반적으로 정부개입과 규제의 대표적인 근거를 제공한다. 하지만 보건의료분야는 정보의 비대칭성, 의료보험의 보편화, 고가의료기술 및 장비에 의한 비용상승 등과 같은 특수성으로 인하여, 정부가 단순히 충분한 의료공급자나 병원의 수를 보장함으로써 가격의 하락과 서비스 양의 증가와 같은 경쟁의 효과를 기대하기 힘들다. 본 논문은 경쟁과 규제와 관련한 보건의료의 특수성과, 보건의료분야에서 경쟁이 소비자 후생에 미치는 영향에 관한 이론 및 실증분석의 결과들을 고찰한다. 나아가 경쟁과 규제가 조화된 지속가능한(sustainable) 보건의료체계를 위해, 병원설비투자의 직접적인 규제로부터 규제를 통해 경쟁을 촉진시키는 인센티브규제(incentive regulation)로서의 지불보상제도 그리고 필요한 정보의 제공을 통한 시장기능의 회복에 이르는, 정부가 집행할 수 있는 효과적인 정책도구들을 분석한다.

  • 본 연구는 현재 조경 설계공모 과정에서 발생되고 있는 문제점을 AHP 기법을 활용하여 분석 및 고찰함으로써 조경설계 공모제도 개선을 위한 기초자료 제시를 목적으로 수행하였다. 본 연구 결과, 첫째, 조경설계공모 제도의 문제점을 이루고 있는 1계층 항목에서는 '당선작 선정과정'이 가장 중요한 문제점으로 나타났고, 그 뒤를 따라 '당선작 이후 설계변화', '조경설계 공모 지침', '조경설계 공모 방식' 순으로 중요도가 나타났다. 둘째, 계층 1을 구성하고 있는 하위 항목에서는 '비 조경전문가의 심사 참여'가 가장 심각한 문제로 의견이 모아졌으며, '심사위원의 전문성 결여', '심사배점방식의 문제' 항목 등 '당선작 선정과정'에 해당하는 하위 요소가 전체 12개의 요소 중 가장 높은 순위를 차지하고 있는 것으로 나타났다. 또한 조경설계공모 당선이 이루어진 후에 일어나는 '발주자의 임의 설계변경 현상'에 대한 중요도도 높게 나타남으로써 조경설계공모의 문제점에서 간과할 수 없는 사항으로 분석되었다. 본 연구는 조경설계공모상 과정에서 발생하는 문제점의 우선순위를 선정함으로써 향후 제도 개선 시 선행적으로 검토가 이루어져야 할 부분을 찾았다는 점에 의의가 있었으며, 이러한 문제점을 근거로 향후 제도개선 방안에 대한 후속연구가 있어야 할 것임이 제안되었다.
