The Brain Korea 21 (i.e., BK21) is a state-led higher education funding project that started in 2013. Previous literature investigating the effectiveness of the project mainly focused on massive quantitative outcomes of funded teams, and many studies reporting only self-reported data of graduate students who participated in the project. Therefore, there were not many BK21 studies that thoroughly examined the graduate students' performance, ability, satisfaction, etc. This study aims to determine the effect of the BK21 project participation on graduate students' academic performance, using objective (the number of published papers), self-rating (graduates' satisfaction), and other-rating (advisor's performance evaluation) data, which were sampled from 2013 to 2019 from a single funded team on a one-departmental-unit. The results showed that the participating graduate students had more published papers, and had higher performance evaluation scores in research, and overall abilities, than the non-participating graduate students. Further, participating students were largely satisfied with BK21 supports. This study has significance in that it demonstrates the positive influence of the BK21 project on graduate students' academic performance and satisfaction by the thorough investigation of a single social science funded team.

As the global business environment changes, uncertainties in technology development and market needs increase, and competition among companies intensifies, interests and demands for R&D activities of individual companies are increasing. In order to cope with these environmental changes, R&D companies are strengthening R&D investment as one of the means to enhance the qualitative competitiveness of R&D while paying more attention to facility investment. As a result, facilities or R&D investment elements are inevitably a burden for R&D companies to bear future uncertainties. It is true that the management strategy of increasing investment in R&D as a means of enhancing R&D capability is highly uncertain in terms of corporate performance. In this study, the structural factors that influence the R&D capabilities of companies are explored in terms of technology management capabilities, R&D capabilities, and corporate classification attributes by utilizing data mining techniques, and the characteristics these individual factors present according to the level of R&D capabilities are analyzed. This study also showed cluster analysis and experimental results based on evidence data for all domestic R&D companies, and is expected to provide important implications for corporate management strategies to enhance R&D capabilities of individual companies. For each of the three viewpoints, detailed evaluation indexes were composed of 7, 2, and 4, respectively, to quantitatively measure individual levels in the corresponding area. In the case of technology management capability and R&D capability, the sub-item evaluation indexes that are being used by current domestic technology evaluation agencies were referenced, and the final detailed evaluation index was newly constructed in consideration of whether data could be obtained quantitatively. In the case of corporate classification attributes, the most basic corporate classification profile information is considered. In particular, in order to grasp the homogeneity of the R&D competency level, a comprehensive score for each company was given using detailed evaluation indicators of technology management capability and R&D capability, and the competency level was classified into five grades and compared with the cluster analysis results. In order to give the meaning according to the comparative evaluation between the analyzed cluster and the competency level grade, the clusters with high and low trends in R&D competency level were searched for each cluster. Afterwards, characteristics according to detailed evaluation indicators were analyzed in the cluster. Through this method of conducting research, two groups with high R&D competency and one with low level of R&D competency were analyzed, and the remaining two clusters were similar with almost high incidence. As a result, in this study, individual characteristics according to detailed evaluation indexes were analyzed for two clusters with high competency level and one cluster with low competency level. The implications of the results of this study are that the faster the replacement cycle of professional managers who can effectively respond to changes in technology and market demand, the more likely they will contribute to enhancing R&D capabilities. In the case of a private company, it is necessary to increase the intensity of input of R&D capabilities by enhancing the sense of belonging of R&D personnel to the company through conversion to a corporate company, and to provide the accuracy of responsibility and authority through the organization of the team unit. Since the number of technical commercialization achievements and technology certifications are occurring both in the case of contributing to capacity improvement and in case of not, it was confirmed that there is a limit in reviewing it as an important factor for enhancing R&D capacity from the perspective of management. Lastly, the experience of utility model filing was identified as a factor that has an important influence on R&D capability, and it was confirmed the need to provide motivation to encourage utility model filings in order to enhance R&D capability. As such, the results of this study are expected to provide important implications for corporate management strategies to enhance individual companies' R&D capabilities.

Vehicles experience changes in driving behavior due to the various facilities on the freeway. These sections may cause repetitive traffic congestion when the traffic volume increases, so safety issues may be raised. Therefore, the purpose of this study is to perform microscopic traffic analysis on these sections using drone images and to identify the causes of traffic problems. In the case of drone image, since trajectory data of individual vehicles can be obtained, empirical analysis of driving behavior is possible. The analysis section of this study was selected as the weaving section of Pangyo IC and the sag section of Seohae Bridge. First, the trajectory data was extracted through the drone image. And the microscopic traffic analysis performed on the speed, density, acceleration, and lane change through cell-unit analysis using Generalized definition method. This analysis results can be used as a basic study to identify the cause of the problem section in the freeway. Through this, we aim to improve the efficiency and convenience of traffic analysis.

2020년 기준 우리나라 전체 지하수 시설은 총 1,659천개소, 이용량은 2,916백만m³/년, 년간 지하수 개발가능량은 130억m³대비 22.3%이다(환경부 등, 2021). 단위면적당 지하수 시설수와 이용량은 16.8개소/km², 29,168m³/년/km²(81.1m3/일/km²)이다. 이러한 자료는 가뭄 대응시 신규 관정 개발도 필요하지만, 기존에 개발된 관정들을 최대한 효율적으로 활용하는 방안을 우선적으로 고려해야 한다는 것을 시사한다. 관정들을 상호 연계하게 되면 여러 개의 관정에서 나오는 물을 합하여 총량을 늘릴 수 있기 때문에, 가뭄 등 비상시에 일시적으로 다량의 물을 공급할 수 있다. 또한, 평상시에도 적절한 양수량 조절을 통해 지하수 자원의 손실을 막고 수위 저하에 의한 문제를 최소화할 수 있다. 관정연계시스템(well network system, WNS)은 기존 관정들을 가상의(virtually) 또는 물리적(physical) 연계를 하여, 최적의 지하수를 공급할 수 있는 시스템으로 정의할 수 있다. 가뭄 대응 및 효율적 지하수 자원 활용을 위한 관정연계시스템 개발과 실증을 위해 홍성군 서부면 양곡리 일대에 양수제어, 관로시설, 물탱크 등 물리적인 시설을 시험 설치하여 운영하고 있다. 또한, 관정연계시스템은 ICT 기술과 지하수관리 기법을 연동하여 지하수 관정들을 연계하고 최적으로 운영할 수 있는 하나의 의사결정시스템으로서 관정연계 플랫폼을 개발하였다. 관정연계 플랫폼은 웹기반으로 개발되었으며, 대수층의 수리지질 특성, 수요에 기반한 물공급량 평가, 관정 연계 시나리오 및 최적 운영 알고리즘, 지하수 모델링 등이 가능하도록 각각의 모듈들이 구성 및 통합·운영 되도록 설계되었다. 본 시스템 개발을 통해 가뭄 발생시 현장에서 신속히 지하수로 물을 공급할 수 있으며, 신규 관정 개발에 드는 비용을 절약할 수 있고, 기존 시설을 활용하기 때문에 새로운 수자원 건설 인프라 구축 비용도 절감할 수 있을 것이다. 또한, 개별관정에 대한 이용률 제고와 지하수관리도 보다 체계적, 과학적으로 할 수 있을 것으로 기대한다. 하지만, 이러한 시스템이 제대로 운영 및 보급되기 위해서는 관정연계와 관련한 법제도적 보완과 함께, 지역사회의 공적자원으로서의 지하수에 대한 인식개선과 지하수의 개발 및 보전, 적합한 합리적 배분·이용 등 적극적인 협조가 이루어져야 한다.

After dismantled, Mireuksajiseoktap(Stone pagoda of Mireuksa Templesite) is being in the stage of restoration design. Now, different ways - producing restoration model, a 3 dimension simulation - have been requested to make more detailed and clearer restoration design prior to confirmation of its restoration design and actual restoration carry-out. This thesis proposes the way to build the detailed model for better restoration plan using extensively-used Reverse Engineering technique and Rapid Prototyping. It also introduces each stage such as a 3-dimension actual measurement, building database, a 3-dimension simulation etc., to build a desirable model. On the top of that, this thesis reveals that after dismantled, MIruksaji stone pagoda's interior and exterior were not constructed into pieces but wholeness, so that its looks can be grasped in more virtually and clearly. Secondly, this thesis makes a 3-dimension study on the 2-dimension design possible by acquiring basic materials about a 3-dimension design. Thirdly, the individual feature of each member like the change of member location can be comprehended, considering comparing analysis and joint condition of member. Lastly, in the structural perspective this thesis can be used as reference materials for structure reinforcement design by grasping destructed aspects of stone pagoda and weak points of the structure. In dismantlement-repair and restoration work of cultural properties that require delicate attention and exactness, there may be evitable errors on time and space in building reinforcement and restoration design based on a 2-dimension plan. Especially, the more complicate and bigger the subject is, the more difficult an analysis about the status quo and its delicate design are. A series of pre-review, based on the 3-dimension data according to actual measurement, can be one of the effective way to minimize the possibility that errors about time - space happen by building more delicate plan and resolving difficulties.

We aimed to revise and supplement the art therapy kit based on the findings of a review of women's experiences participating in the art therapy kit in the 2030s. After women in their 2030s experienced the developed art therapy kit for one month, we organized two homogeneous groups of 8 art psychotherapy majors and 5 non-majors to collect data through focus group interviews and analyzed them using grounded theory methods. In the end, 100 converted meaning units, 16 subcomponents, and 5 components were derived. There is a lack of research on the development and experience of art or art therapy-based kits in Korea, so it is important for us to provide basic data on the experience of art therapy kits. In addition, the study participants experienced insights into themselves and their emotions based on the accumulated art therapy kit outputs through immersion in emotion exploration and recognition, and these experiences led to the participants' recognition of the need and value of developing art therapy kits. The individual and unique outcomes of the art therapy kits became evidence of self-awareness, confirming the therapeutic effectiveness of art therapy kits as a tool for emotion exploration and recognition and for emotional change and resolution.

본 연구는 집중호우에 의한 홍수예측 및 소유역의 유출거동에 대한 수문학적 민감성(susceptibility) 규명을 목적으로 강우강도, 지속기간 및 토양포화도 변화에 따른 홍수유출특성을 분석하여 유역의 유출거동 민감성을 표출할 수 있는 노모그래프를 개발하였다. 개별 홍수사상에 대한 유출거동 특성 분석을 위하여 한국건설기술연구원의 대표 시험유역인 설마천 유역의 과거 17년간(1996 ~ 2012)의 10분 간격의 강우량 및 유출량 자료를 수집하여 홍수유출해석을 수행하였다. 설마천 시험유역의 일누가강우량 100mm 이상, 50개 홍수사상에 대한 홍수유출해석은 유역 물순환 해석모형인 CAT(Catchment hydrological cycle Assessment Tool)을 이용하였으며 모의결과를 바탕으로 홍수사상별 지체시간, 강우강도, 지속기간 및 토양포화도 변화에 따른 홍수유출특성을 상세히 분석하였다. 이 중에서도 지체시간은 유역반응을 나타내는 시간변수로서 수문모델링 및 홍수량예측에 매우 중요한 요소이다. 특히, 강우량에 대한 홍수량의 반응이 빠른 소유역의 경우에 홍수량예측에 큰 영향을 미친다. 따라서 강우강도, 지속기간, 토양포화도의 변화량에 대한 지체시간의 거동을 R 프로그래밍 언어 및 3D Surfer를 이용하여 분석한 후 최종적으로 소유역의 홍수유출 특성을 나타내는 3차원 홍수 유출특성 노모그래프를 개발하였다. 분석에 사용된 R 프로그래밍 언어는 통계 계산과 그래픽을 위한 프로그래밍 언어이자 소프트웨어 환경으로 데이터의 조작 및 수치연산, 시각화를 수행할 수 있는 기능을 여러 패키지를 통해 구현할 수 있다. 따라서 본 연구에서는 R을 이용하여 10분 단위의 강우 및 유출량 자료를 1시간 및 1일 자료로 구축하고 17년간의 과거 홍수사상을 분리하여 추출하는 R 홍수유출해석 시스템을 개발하였으며 추출된 홍수사상을 관측 유출량 및 관측 토양수분을 포함하여 시각화함으로써 강우 및 토양수분 변화에 따른 소유역의 유출거동 민감성을 확인할 수 있었다. 분석 결과, 지체시간은 강우지속기간 및 토양포화도에 민감한 거동특성을 나타냈으며 토양포화도는 첨두홍수량의 변화에 민감한 영향을 주는 것으로 확인되었다. 개발된 3차원 홍수유출특성 노모그래프는 유역의 규모 및 지형물리학적 특성에 따라 다양하게 나타날 것으로 판단되며 여러 계측유역에 적용함으로써 유역별 홍수유출 반응특성을 정량화할 필요가 있다. 즉, 강우강도, 지속기간, 지체시간, 포화도 등의 변화에 따른 유역의 홍수유출 반응특성을 규명함으로써 미계측 유역의 홍수량예측 실무에 활용할 수 있을 것으로 판단된다.
