Mooodcd: Multi Objective Optimization Overlapping Dynamic Community Detection

Detecting dynamic communities in complex networks provides revealing and studying of these ‎networks' organizational principles. Dynamic topological structure ‎and node attributes are the two sources of data that can be ‎utilized to increase the performance of community detection. Various approaches have been proposed in this regard to ‎detect ‎communities in networks by utilizing their topological structure and node attributes while they have not addressed the dynamic topological structure, or current ‎approaches only employ one of these data ‎sources. By utilizing topological structure and ‎ node attributes, and also using the Dirichlet ‎distribution to control ‎the dynamics of the network, in this research we develop a Multi-‎Objective ‎Optimization Overlapping Dynamic‏ ‏Community Detection (MOOODCD). MOOODCD ‎models the problem of dynamic community detection in dynamic networks as a non-negative ‎matrix factorization problem. The latent factors of the model are estimated by using the block ‎coordinate decent method. The runtime of MOOODCD is related to the network size. Experiments ‎on artificial and real networks show that MOOODCD has a high degree of accuracy and scalability ‎for detecting overlapping communities in dynamic networks. ‎

Knowledge map construction of multi-source heterogeneous contaminated site data

The retirement and relocation of urban industrial enterprises has led to the retirement of a large number of contaminated sites.Aiming at the problem that the data related to the contaminated site comes from many different sources and has different structures, and it is difficult to explore the potential correlation between the data through the existing management methods, this paper proposes a knowledge map construction method for multi-source heterogeneous data of the contaminated site.According to the different structures of contaminated site data, we use the knowledge construction theory to select appropriate entity recognition, relationship recognition and knowledge fusion methods to extract various types of information of contaminated sites and establish semantic networks.The knowledge map constructed for a contaminated site in Northeast China contains 3840 contaminated site entities including site information, enterprise information and soil information, and the corresponding association relationship is 4768.Practice has proved that the proposed knowledge map construction method can effectively and intuitively represent the potential association relationship between contaminated site data, and provide corresponding technical support and decision-making information for the relevant departments of contaminated site restoration and management.
Mitigating Representation Bias in Action Recognition: Algorithms and Benchmarks

Deep learning models have achieved excellent recognition results on large-scale video benchmarks. However, they perform poorly when applied to videos with rare scenes or objects, primarily due to the bias of existing video datasets. We tackle this problem from two different angles: algorithm and dataset. From the perspective of algorithms, we propose Spatial-aware Multi-Aspect Debiasing (SMAD), which incorporates both explicit debiasing with multi-aspect adversarial training and implicit debiasing with the spatial actionness reweighting module, to learn a more generic representation invariant to non-action aspects. To neutralize the intrinsic dataset bias, we propose OmniDebias to leverage web data for joint training selectively, which can achieve higher performance with far fewer web data. To verify the effectiveness, we establish evaluation protocols and perform extensive experiments on both re-distributed splits of existing datasets and a new evaluation dataset focusing on the action with rare scenes. We also show that the debiased representation can generalize better when transferred to other datasets and tasks.
Reflection on the purpose of social welfare education and future tasks

한국의 사회복지교육에 대한 개혁 논의는 근본적 문제의식과 달리 자격주의(credentialism), 전문가주의(professionalism) 강화로 전개되며, 사회복지교육의 정체성을 되찾는 근본적 해법과는 거리가 멀어져 왔다. 사회복지교육에 대한 보다 근본적 논의를 위해서는 사회복지교육의 목적성에 대한 성찰이 필요하다. 따라서 이 글에서는 사회복지교육의 목적성을 성찰하고, 제한적인 교과과정 내에서 핵심 교과내용으로 재구성할 수 있는 개혁방향을 모색하고자 한다. 사회복지교육의 목적성은 더 나은 삶과 더 나은 사회를 위해 사회정의 가치를 추구하는 전문적 실천을 할 수 있는 전문인력을 양성하는 것이다. 이를 위해 가치, 지식, 기술의 내포적 관계를 사회복지실천의 성찰(reflection)이라는 교육방법으로 통합해내는 것이 중요하다. 이와 같은 사회복지교육 개혁을 위해 다음과 같이 제안하였다. 첫째, 사회정의 가치 실천이라는 사회복지교육의 목적성을 명확히 하고, 변용가능한(transformative) 핵심역량을 키울 수 있는 핵심 교과목 및 교과내용의 재구성이 필요하다. 둘째, 사회복지실천현장의 교육수요로부터 핵심역량을 구성하는 교과과정을 귀납적으로 재구성하고, 기본 공통영역과 전문영역의 교과과정으로 분류하고 모듈식으로 체계화하는 것이 필요하다. 셋째, 자격제도와 사회복지교육의 개혁 과제를 분리하는 것이 필요하다. 넷째, 가치-지식-기술의 통합적이고 성찰적 교육을 위해 사회복지현장의 실천 사례들을 체계적으로 축적하고, 사회복지 교과서를 새롭게 개발하며, 교수자의 혁신을 위한 교수 재교육이 필요하다.Unlike the fundamental awareness of the problem, the discussion on the reform of social welfare education in Korea has been developed with the strengthening of credentialism and professionalism and has been far from a fundamental solution to regaining the identity of social welfare education. For a more fundamental discussion on social welfare education, it is necessary to reflect on the purpose of social welfare education. Therefore, in this article, we reflect on the purpose of social welfare education and seek reform directions that can be reconstructed into a core curriculum within the limited curriculum. The purpose of social welfare education is to nurture professionals who can practice professionally pursuing the value of social justice for a better life and a better society. To this end, it is important to integrate the inclusive relationship between values, knowledge, and skills into an educational method called reflection in social welfare practice. The following proposals were made to reform social welfare education. First, it is necessary to clarify the purpose of social welfare education, which is the practice of social justice values, and to restructure core subjects and contents that can develop transformative core competencies. Second, it is necessary to inductively reorganize the curriculum that composes core competencies from the educational demand in the social welfare practice field, classify it into basic common areas and specialized areas, and systematize it in a modular way. Third, it is necessary to separate the reform task of the qualification system and social welfare education. Fourth, for value-knowledge-technology integrated and reflective education, it is necessary to systematically accumulate practice cases in social welfare fields, develop new social welfare textbooks, and retrain professors for innovation of instructors.
Categorizing Factors Associated with Artistic Creativity and Exploring its Educational Implications

본 연구는 미술적 창의성(artistic creativity)의 구성 요소를 조작가능한 형태로 범주화하는 것을 그 목적으로 한다. 구성 요소 추출을 위하여 미술적 창의성을 다룬 논문 17건을 탐색 및 분석한 후 능력 구분에 기반하여 2개의 능력 영역과 14개의 하위 구성 요소를 범주화하였다. 분석 결과 미술적 창의성의 구성 요소는 인지·표현 능력 영역에 직관, 상상력, 사고양식의 전환, 연결 능력, 시각화 능력, 독창성, 적절성, 유창성, 융통성의 9개 요소가, 정의적 능력 영역에 감수성, 몰입, 자율성, 호기심, 개방성의 5개 요소가 도출되었다. 미술적 창의성의 구성 요소는 일반적인 창의성 문헌에서 언급되는 요소들과 유사 하였으나, ‘시각화 능력’은 미술 영역에 고유한 능력으로 나타났다. 나아가 이들 구성 요소를 이용하여 미술 교과에서 창의성을 평가하는 항목으로 본 요소를 이용할 수 있음을 제안하였으며, 타 영역 창의성과의 비교를 통해 융합교육에서 미술교육이 창의성 교육에 기여할 수 있는 지점을 검토하고, 인공지능 시대 미술 창의성의 의미 변화 가능성을 고찰하였다.This paper aims to find factors associated with artistic creativity as an operational definition. To this end, the author explored and analyzed seventeen articles dealing with artistic creativity. The factors categorized into two main domains and fourteen subcategories. Cognitive and expressive domains consist of nine factors: intuition, imagination, shifting between modes of thinking, connecting skill, originality, appropriateness, fluency, flexibility, and visualization. An affective domain consists of five factors: sensitivity, flow, autonomy, curiosity, and openness. Although factors of artistic creativity were similar to those of general creativity, “visualization” was a unique feature in the art domain. The author suggests that these factors can be used to assess creativity in art class, considers the possibility of art education’s contribution to creativity improvement in convergence education, and thinks about the change of the meaning of creativity in the era of artificial intelligence.

Development and Characteristic of Logic of Teaching and Learning in the Early Korean Social Studies, 1945-1955

이 연구는 우리나라 사회과 성립기에 나타나고 있는 교수·학습론의 특징을 고찰하였다. 이 시기는 신생 교과의 계몽기와 교육과정 개조 운동 시기로 구분할 수 있다. 앞의 시기는 해방 이후부터 1940년대 말까지에 해당하며, 사회과 교수요목의 해설이라는 차원에서 사회과수업 방법의 안내가 행해졌다. 그 당시 수업방식이 독본식 수업형태로 한계가 있었는 바, 그 대안의 모색은 문제해결학습의 아이디어였으며, 이러한 문제해결학습론의 실체를 러그의 사회과 수업론 측면에서 소개하기도 했다. 교육과정 개조 운동 시기는 1950년대 시작 무렵부터 1955년 1차 교육과정 공표 시기까지이며, 현장 교사들의 중핵 교육과정 구성과 실천에 초점이 있었다. 중핵교육과정으로 학교 교육과정을 편성할 때, 핵심적인 교과는 사회생활과였고, 학생들이 지역사회 생활교육의 과정으로 사회인식활동을 하도록 했다. 두 시기 동안의 공통점으로 사회과수업은 단원학습의 과정 속에서 문제해결을 능동적인 참여활동으로 시도하도록 했다는 점이다. 차이점은 신생 교과의 계몽기보다는 교육과정 개조 운동 시기가 현장 교사 개개인들의 능동적인 실천을 시도하였다는 점에 주목해 본다.This research examined the logic of teaching and learning that appeared in the establishment period of Korean social studies. This period can be divided into the period of enlightenment of social studies as a new subject(1945-1949) and the period of the curriculum reform movement(1950-1955). In the former period, the social studies teaching method was limited to the form of textbook-reading instruction, and the search for an alternative was the idea of problem-solving learning, and the principle of this problem-solving learning theory was introduced in terms of Harold Rug's social studies theory. In the period of the curriculum reform movement, the focus was on the composition and practice of the core curriculum of elementary school teachers. When elementary school teachers organized the school curriculum as a core curriculum, the core subject was social studies, and students were required to engage in social cognition activities as the process of life education in their community. The commonality between the two periods is that learners were actively involved in problem-solving learning in the process of social studies unit learning. The difference is that the period of the curriculum reform movement encouraged the active educational practice of elementary school teachers rather than the enlightenment period of the new subject.
Development and Application of an Instruction-Based Contemporary Art Education Program for Preservice Teachers: An Action Research Study

본 연구는 지시문 기반 예술에 대한 이론적 탐색을 진행한 연구(김수진, 2022)의 후속 연구로서, 초등 예비 교사를 위한 지시문 기반 예술 교육 프로그램을 개발하여 적용한 실행 연구이다. 초등 예비 교사들은 미술만을 전공으로 하고 있지 않기 때문에 현대/동시대 미술에 대해 생소하게 느낄 수 있다. 그러나 초등 교육과정에서 현대/동시대 미술에 대해 다루는 것은 시대적 흐름이며 따라서 구체적인 교수법에 대해서 논의를 진행할 필요가 있다. 본 연구에서는 20명의 미술교육 관련 필수 교과목을 수강하는 초등 예비 교사인 대학교 3학년 연구 참여자들과 함께 현대/동시대 미술 작업들을 탐색하고, 이를 기반으로 지시문을 생성하고 수행하는 흐름의 교육 프로그램을 진행하였다. 연구 참여자들의 성찰지를 수집하여 주제를 중심으로 질적 분석한 결과, 초등 예비 교사들은 미술 수업에 대한 새로운 관점을 형성하고, 지시문 생성과 수행을 통해 현대/동시대 미술에 대한 이해를 도모했으며, 현대/동시대 미술 교수법에 대한 역량 강화를 추구했다. 실행 연구의 순환적 과정에 기초하여 연구자 또한 프로그램의 결과를 성찰하고 재계획 방향에 대해 논의하였다.This is a follow-up study of a study (Kim, 2022) that conducted a theoretical examination of instruction-based art. Preservice elementary teachers may feel unfamiliar with contemporary art because they do not specialize only in art education. However, the discussion of contemporary art in the elementary curriculum is moving from whether it is necessary to what the specific teaching methods are. Thus, in this study, I conducted an action research study with 20 preservice elementary teachers. The research participants explored contemporary artworks, created instructions, and carried them out. I collected reflection portfolios and qualitatively analyzed them utilizing a theme-based approach. As a result, the preservice teachers formed new perspectives on art lessons, improved their understanding of contemporary art by doing, and strengthened their competencies in art pedagogy. The researcher also reflected on the process.
How do We teach Republican Citizenship in the Classroom? : Focusing Cicero and Machiavelli’s discourse

최근 한국 민주주의의 문제로 파당적 포퓰리즘, 전문가 가디언 집단의 발흥, 정치의 사법화, 정치적 양극화 등이 제기되고 있다. 이러한 문제의 해결 방안의 하나로 공화주의가 제시되고 있다. 이러한 상황에서 본 논문은 로마 공화주의의 이상과 구조와 특징들을 살펴보고, 공화주의적 시민성의 의미와 의의, 구조 그리고 이를 가르치기 위한 몇 가지 교수학습 아이디어를 제시하고 있다. 본 연구결과를 제시하면 다음과 같다. 공화주의는 사회의 다양한 제 세력들 간의 조화와 균형, 공존, 공공성, 공동 번영을 추구하는 정치이념을 말한다. 공화주의는 사회의 다양한 제 세력들 간의 조화와 균형, 공존, 공공성, 공동 번영을 실현하기 위하여 비지배로서의 자유, 평등, 권력분립(견제와 균형), 법의 지배, 정치참여, 정치적 수사, 다원성/복수성/연방성, 겸손과 절제/의무감, 갈등의 가치와 관리, 공공성, 애국심과 같은 요소들을 필요로 한다. 공화주의적 시민성은 개인 및 집단의 개별성과 차이, 복수성, 연약성 그리고 이들 간의 갈등을 인정하고 존중하면서도 일련의 정치적 과정을 통하여 조화와 균형, 공존, 공공성, 공동 번영을 추구해 가는 시민성이라고 할 수 있다. 이러한 공화주의적 시민성은 시민의 자질로 정의와 공공선에 대한 의식이 요구된다는 점, 역량과 영예와 더불어 자제와 겸손이 요구된다는 점, 권리와 더불어 의무와 책임이 강조된다는 점, 토론과 대화에서 이성적 논의와 더불어 감정적이고 일상적인 대화가 요구된다는 점에서 근대적 시민성과 차별성을 갖는다.Recently, It is said that Korean democracy is facing many problems such as partisan populism, the rise of expert-guardian group, judicialization of politics, failure of representatives, political polarization etc. In order to resolve these problems, some scholars is suggesting republicanism as a one solution. The aims of this paper is to search the ideal and characteristics of roman republicanism and examine republican citizenship and suggest activities for teaching republican citizenship. The results of study are as follows. The republicanism is the political idea that pursues harmony, balance, co-existence, public good, common prosperity among various groups. In order to achieve harmony, balance, co-existence, public good, common prosperity among various groups, Republicanism needs freedom as non-domination, equality, division of powers(check and balance), rule of law, political participation, political rhetoric, plurality and unity, humility/moderation/duty, management of conflict, public good, patriotism etc. Republican citizen means the citizen who admit and respect individuality, difference, vulnerability, plurality of each person groups, and conflicts among persons and groups, and try to build co-existence, public good, common prosperity among various persons and groups through a republican political process. Republican citizen needs the sense of justice and public good, and self-control and modesty as well as excellence and glory, duty and responsibility as well as right, emotion and dialogue as well as rationality and logic in dialogue and discussion. These characteristics make republican citizenship different from modern democratic citizenship.

To this end, a case study was conducted in which the contents of the field training were composed based on the main services of the community children center and the standard practice training manual, and the interview data of supervisors, trainees, and practice materials of the training institution were collected and analyzed. The results of the study are as follows; First, social welfare field training was being conducted at a community children center as the interests of the training institution that wanted to secure human and material resources and the trainees who had difficulties in selecting a training site in the field of interest coincided. Second, as for the contents of the practical education, an experience centered on protection and learning mentoring is being made under the influence of Covid 19, and the practical contents of the five service areas of the community children center were provided as a method of education. The training institute had difficulties in dealing with a lot of content in a short period of time(160 hours), and the trainees needed to expand their various experiences, such as interviewing children and planning and operating various programs. Third, it was deduced that it was necessary to improve the operating system based on exchanges between training institutions in order to substantiate the practice of community children centers. Based on the research results, a plan to operate a common practice education by forming a field practice consortium at a community children center in the local community was presented with practical implications.
