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.

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.

A deserted town once vibrant with active commercial activities around a railroad station now tries to find a way to escape from depression and revive its life with a renewed civic pride. An open space adjacent to the Main Street, the commercial district of Buzzards Bay, Massachusetts, is waiting to be transformed and reconfigured to be a new ecological park to boost the economy of the community. Bridge Park is 26-acre land abutting the Cape Cod Canal with a railroad bridge as a backdrop. The existing condition of the site with a small salt marsh, woodland, lawn, and the vestige of old railroad easement along with the proximity to the commercial district poses an interesting question of how to make a medium scaled ecological park within an urban context. This paper examines the winning design proposals for the Bridge Park submitted to the International Design Competition held in April, 2005. Six winning proposals were introduced and discussed in terms of categories related to the trend of contemporary landscape design such as; 1) ecological ordinariness and geometric figures, 2) topography and spatial imagination, 3) minimal programs and open put 4) time and process oriented design, 5) park and economic effects and 6) diagrammatic plan and photo montage. Bridge Park Design Competition confirms the complex characteristics representing the contemporary landscape design overcoming the dichotomy between nature and culture and the 'pastoral ecological design' and 'landscape as an art'. The Park becomes the activating agent for the community rejecting the conventional and passive role as a romantic picturesque landscape. Bridge Park International Design Competition is a meaningful event to test the idea of new ecological urban park, and to fine-tune the trend of the contemporary urban park design.

The purpose of this study is to know the important design element for a public library, after analyzing design concept and organization of space of the prize winner at the architectural competition. To carry out the research, the best 31 works between the year of 2005 and 2010 were collected by the architectural magazine A&C published in every other month. During the research, special characters of each prize winner have been analyzed in the aspect of the design concept and the organization of space. While working on the design concept, a factor that created such concept was successfully figured out, and studying on the organization of space enabled us to know the special characters of the interior space. According to the result of the analysis in this study, the design elements which are selected highly frequent are ordered as follows; (1)organization of space, (2)function & shape, (3)circulation, (4)landscape, (5)symbolic aspect. Through the analysis for the organization of space, I reach a conclusion, the frequent type is a "PM-ES-CJ". The study is anticipated to be helpful in understanding the trends in the field of designing a public library, and it is also likely for an architect to use it as a reference.

The objective of this study is to critically examine the result and the quality of urban park design as infrastructure by analyzing the landscape architectural design competition for Cheongna New City, which was organized by the Korea Land Corporation. This paper is meaningful in that it broadly examines several recent design competitions for urban parks, thereby discussing what the future urban park should be. This study explores the existing analysis methods of design competitions in order to establish a comprehensive method of analysis for the Cheongna competition. Through reinterpreting the concept of the urban park as infrastructure and the design strategies of landscape urbanism, nine key words and a framework for the analysis of urban park design are established. By analyzing the guidelines for the competition, five key words; networking, site, ecology, scale, and infrastructure have been selected and are used as the framework of analysis for the competition. The analysis of the contestants of the competition based on the proposed analysis method leads to a few implications for urban park design as infrastructure: networking and scale from the perspective of the development site; the creation of a sense of place and symbolism in creating the urban image; planning for an ecological urban environment; focus on the significance of the urban park as infrastructure. These implications are highlighted and discussed by the contestants through a variety of experiments. These ideas, however, are provided as a simple configuration of shapes and conceptual explanations and fail to be developed into synthetic, practical strategies.
