This paper tried to analyze cases of one year team-based project of gifted students who spent two year programs in a math-IT integrated class as part of formative evaluation and extracted the factors associated with future enhancement for the program. The researcher as an advisory professor tried to guide the students as minimally as possible considering their levels of IT skills so that they could self-directedly perform the IT-fused project on a team basis. The data collection included documents, annual report, photos, video, artifacts and interview data with the students for the whole team project carried out between February and December, 2015. The overall pattern of the project activities has been stabilized in the middle of the course compared to the initial stages of brainstorming and design work even though the students revealed the differences of their programming skills and preferences toward the project theme. Their project outcomes were qualitatively analyzed according to the 9 steps of R&E model and has shown individual differences according to low, middle and high level. At the end, the analysis suggested several implications for further improvement of the mentorship program.

This study investigated a 7-week summer science research apprenticeship program for gifted high school students in U.S. The purpose of the study was to examine the reasons why the high school student participated in the program, the students' perceptions on the benefits of the apprenticeship program, and to investigate mentors' perceptions on assessment and mentorship of the students' projects. For this study, laboratory works and group meetings were observed, students' journal and research products were analyzed, and interviews were administrated with student apprentices and some mentors. The result revealed that the main reasons of students' participation were to perform research with university professionals, to understand the scientific research, and to explore their college/career decisions. Students' participation was strongly associated with their internal motivation and interests. The students perceived the benefits of the apprenticeship program as providing them with the experience of the nature of real scientific research, of learning of scientific knowledge on the focus area, and wiser college/career decisions. Students' projects were assessed and guided through on-going interactions and cognitive apprenticeship between mentors and student apprentices.

Recently, cultural property policies have changed from the preservation of cultural assets to the utilization of cultural assets. In historic villages, more and more traditional housings have been used as lodging facilities. On the other hand, low birth rates, aging population, declining population due to population outflow to the cities, increasing vacant houses, and aging buildings are tasks of historic villages. To be preserved the historic villages continuously, it is time to review how to regenerate and utilize the growing number of vacant houses. This study targets Tambasasayama city, which is drawing attention to the regeneration and utilization of vacant houses among historic Japanese villages. We want to analyze the operation systems and deregulation of a traditional housing regeneration project in Tambasasayama city and draw suggestions for the regeneration and utilization of vacant houses in traditional villages in South Korea.

Art sponsorship contributed to the development of culture and art by supporting art activities to be financially stable. Various problems in the non-fungible tokens (NFTs) market, such as speculative transactions, are also expected to be improved through sound art sponsorship. This study proposes methods of implementing art sponsorship using NFTs and smart contracts. First, we propose a method of posting the acknowledgement of art sponsorship using NFT metadata. Second, we propose a method to remit sponsorship funds according to the project schedule using time-locked wallets. Third, we propose a method to remit sponsorship funds when major events of the project occur or requirements are met using Event-Driven Execution. The proposed methods can be used to share the fact about art sponsorship and safely fund it. However, many decisions about art projects must be made based on information generated outside the blockchain, which can lead to Oracle problems, so further research is needed.

Electronic detonators are widely used in various construction sites due to accurate delay time. Including the cases with exceeded noise and vibration from site using electric/non-electric detonator, electronic detonators are used to improve blast fragmentation or to reduce the cost of secondary partial blasting. Furthermore, the number of cases using electronic detonators are increased for reduction of the cost and construction period by maximizing operations efficiency. This case study is about applying electronic detonators on large section station, tunnel construction site which is the part of urban area GTX A project. Although it was initially planned to utilize non-electric detonators, damage was inflicted on safety-thing. We have considered blasting method using electronic detonators as solution of this problem. By applying electronic detonators, we not only satisfied environmental regulations but also prevented nearby safety-thing from getting damaged. In addition, we were able to shorten the construction period than the initial plan by conducting single simultaneous blasting on large section station, in order to ensure safe and efficient construction.

In Korea, efforts have been made continuously to improve the environment of traditional markets concerning the issues of urban regeneration. In particular, many old cities and traditional markets face a lack of parking spaces. As a solution to this, attempts are being made to prepare underground parking spaces by designing urban planning facilities in three-dimensional ways and utilizing the upper part as a more meaningful space. This study is about the master plan to use the upper green area while creating an underground parking lot at 571 Sinmae-dong, Suseong-gu, Daegu. This green area was defined as a space with dual values, 'defensive green space' that needs to be ecologically protected, and 'active cultural space' where walking flows to the market and various events are concentrated. Three specific design strategies to balance these values were presented. First, to prevent indiscriminate occupation and damage by people and maintain a healthy green environment, securing the maximum amount of undivided green space in the site was suggested. Second, a space layout and a topography and planting patterns that can overcome the morphological characteristics of narrow and long-shaped sites enable the experience of abundant green spaces. Third, providing space to strengthen the connections with nearby urban facilities such as Sinmae Market and Gosan Library can also intensively accommodate cultural activities in various cities. This study has academic significance in providing implications for urban regeneration projects with similar contexts in the future.

The ongoing Yongsan Park development project began in 1988 with the development of a utilization plan for the US Army base in Yongsan after the Army relocation. This study aimed to draw implications for the Yongsan Park project by focusing on Yongsan Family Park. Among the public records of Yongsan Park and Yongsan Family Park transferred to the Seoul Metropolitan Archives, 53 major records were analyzed. The results are as follows. First, Yongsan Family Park, built on the site of the US Army golf course in 1992, was considered a part of the Yongsan Park plan and holds status as the first phase of the Yongsan Park project. Second, despite its status, Yongsan Family Park opened as a temporary park occupied by urban facilities. A design and detailed roadmap of the development process is necessary to make Yongsan Park more resilient. Third, organizing and systematizing public records is necessary because lessons learned through past park development processes can be applied to the current project. This study is meaningful since it uncovered important issues of urban planning discussed in the process of Yongsan Family Park development through a complete analysis of public records, examined the linkage between Yongsan Family Park, which was not known until now, and the ongoing Yongsan Park project, and reaffirmed the importance of park archiving for long-term development projects.

The purpose of this study was to investigate the educational factors on career choice of science-gifted students to science and technology bound universities and the difference of perception in regards to group factors. In addition, this study aimed to examine the effects of science-gifted education and critical events in relation to career choice to science and technology bound universities. For the study, 104 university freshmen, 75 males and 29 females, were sampled from UNIST (Ulsan National Institute of Science and Technology), that many science high school graduates entered this year. The survey was conducted with questionnaires to do with the perceptions concerning career choice and educational factors that cause them to choose such career directions. The educational factors on career choice to science and technology bound universities were classified as 3 main categories such as educational environment factor (teaching-learning factor), human factor, attitude towards science factor and the subcategories within each category. The research findings are as follows: First, the factors were closely connected with each other and 'the project centered classes' were highly interrelated with other educational environment factors such as 'the experiment activity and environment for the activity' and 'influence of teachers (professors).' Second, the female students and graduates of the science high school were more positively influenced by the educational environment and human factors on their decision for career than male students and graduates of the general high school. Third, this research found that historical scientific knowledge, perception of scientists' social status and job applications in the science field gave less influence rather than other factors on their decision for career. As a result of examining critical events for science-gifted education in relation to career choice to science and technology bound universities, numerous students mentioned that the extracurricular science activities such as science camps and field trips gave significant effects on students' career choices to science and engineering fields.
