A Multi-Domain Web Text Feature Extraction Model for e-Science Environment

Weng Yu 보안공학연구지원센터 2015 International Journal of Signal Processing, Image Vol.8 No.11

The traditional information extraction methods based on specific domain usually depend on the domain dictionaries to discover the text feature. It is inconvenient for reproducing and difficult to transplant in multi-domain environment. The application scope is limited seriously. Oriented to the deficiencies above, a multi-domain web text feature extraction model for e-Science is proposed (named e-FTM). This model adopts the Chinese split words technology without dictionary into the process of multi-domain text feature discovery and avoids the dependency of domain dictionaries effectively. With the help of classification of common and individual features, the model tracks the generation and the development trend of domain events dynamically, and forms a couple of local data centers eventually. Through cooperative scheduling the domain knowledge between different local data centers, the knowledge utilization efficiency of the domain information in the global scope is improved sharply. To validate the performance, the experiments on the multi-domain text feature extraction, topic features dynamical tracking and the domain knowledge cooperative scheduling demonstrate that the model has higher application validity and practicality in e-Science environment.

A Study on the Multi-Domain Environment and Revolution in Military Affairs of the Korean Military

Jaseong Baek,Jiwon Yun J-INSTITUTE 2022 International Journal of Terrorism & National Secu Vol.7 No.1

Purpose: The purpose of this paper is to analyze the impact of the technology of the fourth industrial revolution on the changes in the operational environment, and present the operational employment concept and military buildup related directions of the Korean armed forces in accordance with the changed operational environment in terms of revolution in military affairs. Method: The existing studies of domestic and foreign academics on combat domain, fourth industrial revolution, revolution in military affairs, and joint operations, etc., and the literature focused on research papers published by the Joint Chiefs of Staff and the Army were explored. Based on which, the historical evolution process of technology and domain was examined, and after deriving the evolutionary direction of the field that the fourth industrial revolution will bring, an exploratory approach was attempted to present the joint operational concept and military buildup related direction in line with the characteristics of the new domain. Results: The impact of the fourth industrial revolution across all sectors of society is reflected in the military field as well, fundamentally changing the concept of weapon systems and military operations. The advancement of military science and technology is creating a multi-domain environment by expanding the cross domain. In such a multi-domain environment, joint operations ought to include not only the integrated operation of traditional military types, but also the integrated operation of the domain at the same time. Furthermore, it was confirmed that in order to secure cross domain capabilities appropriate for the multi-domain environment, it is necessary to review the basic concept of joint operation, develop a new paradigm for the appropriate allocation of capabilities, and set a variable point of equilibrium for efficient operation of capabilities. Conclusion: Revolution in military affairs is a process which dramatically amplifies combat effects by developing a new power system by applying the new military science and technologies, and innovatively developing and harmoniously operating joint operational concept and the organizational structures related thereto. Hence, approaching the multi-domain operation (MDO) of the US Army in terms of revolution in military affairs rather than operational aspects will offer useful implications for the Korean armed forces.

In addition, the program saw statistical differences on environmental attitude· values and sensibilities, which were subcategories of the affective domain. Among the subcategories of the behavioral domain, positively affected were categories of persuasion·encouragement, practice related to the environmental problems and environmental function that enhance active involvement and practice of environmental problems. Secondly, the environmental science exploration program didn't bring meaningful differences to the scientific attitude.

한국의 해양영역인식에 관한 연구 - 해양영역의 변화를 중심으로 -

백병선 한국해양수산개발원 2018 해양정책연구 Vol.33 No.1

In the past, Maritime area was mainly a domain of national security, but it is came to be expanded into the domain of trade and exchanges between countries after Cold War. In particular, coastal nations were strengthened under United Nations Convention on the Law of the Sea which promoted the awareness change of maritime domain. Therefore it is necessary to have a comprehensive understanding of the maritime domains in order to effectively sustain the survival and prosperity of the nation in the age of the sea. This study formulates South Korea’s concept of the Maritime Domains Awareness based on the changes into awareness of the Maritime Domains such as security, safety, economy, environment, and cooperation. 해양의 중요성이 더욱 증대하게 되자 일부 국가들은 해양영역인식(Maritime Domain Awareness), 즉 해양영역에 영향을 미칠 수 있는 모든 분야에 대한 효과적인 이해를 통해서 해양영역에 관한 제반 정책과 활동을 강화해 나가고 있다. 미래의 바다는 한국의 생존 및 번영, 그리고 국민행복의 성장 동력이 될 것으로 예상되는 가운데 한국의 해양에 대한 의존성이 더욱 증가하고, 해양영역도 확대된다는 측면에서 해양영역을 정부 부처별 개별적으로 인식하기보다는 국가적 차원의 해양영역인식을 기반으로 미래 해양의 시대에 국가의 생존과 번영을 효과적으로 이어가야 할 것이다. 이에 따라 본고에서는 한국의 해양영역에 대한 인식 변화를 분석하고, 이를 바탕으로 안보, 안전, 경제, 환경, 협력 등 5가지 영역을 중심으로 한국의 해양영역인식에 대한 개념을 정립하였다.

본 연구는 창의적 수업환경과 영역별 창의성의 관계를 알아보고, 한국과 미국의 창의적 수업환경을 비교하고 보완할 점을 조사하는 데 목적이 있다. 이를 위해 서울, 경기, 충남, 경남 지역의 4년제 대학교 학생 1174명과 미국의 주립대학교 학생 551명을 대상으로 창의적 수업환경 질문지와 영역별 창의성 검사를 실시하고 자료를 분석하여 다음과 같은 결과를 얻었다. 첫째, 창의적 환경과 영역별 창의성 간에 유의한 상관이 있었다. 둘째, 높은 창의적 수업환경을 가진 학생이 낮은 창의적 수업환경을 가진 학생보다 모든 영역의 창의성(일상생활에서의 창의성, 학문적 창의성, 음악/문학에서의 창의성, 기계/과학 창의성, 예술적 창의성)에서 유의하게 높은 점수를 보였다. 셋째, 미국 학생들이 한국 학생들에 비해 좋은 창의적 수업환경을 가지고 있었다. 넷째, 미국 학생들이 한국 학생들에 비해 영역별 창의성에서 우수한 능력을 보여주었다. 다섯째, 한국에서 수업환경에 대한 요구는 “일반적이지 않은 질문에도 긍정적인 반응을 해주는 선생님이 있는”과 같은 교수의 태도 및 심리적인 요구가 높았으나 미국에서는 이에 대한 요구는 후순위였고 그보다 “수업이 일상생활에 도움이 되도록 하는 것”과 ,“토론 위주로 수업하는” 등 실생활적인 요구가 한국에 비해 높았다. 이러한 결과를 바탕으로 각국이 창의적 수업환경 조성을 위해 초점을 두어야 할 점들이 논의되었다. The purposes of this study are to examine the relationships between professors attitude & psychological factors and teaching-learning method related to creative class environment and domain specific creativity; to compare creative class environment in Korea and U.S.A., and to suggest complementary measures following the research. To achieve these purposes, this research surveyed 1174 university students from Seoul city, Gyeongi, Chungnam and Gyeongnam provinces in Korea and 551 state university students in California, the United States. We asked the questionnaires about creative class environment and ran the domain specific creativity test. The research analysis results are as follows. First, there exists significant correlation between the creative environment and domain specific creativity. Second, the students with high creative class environment displayed higher scores at all areas of the domain-specific creativity (Self/Everyday, Scholarly, Writing/Music Performance, Mechanical/Scientific and Artistic) than the students with low creative class environment. Third, American students had a better creative class environment compared to the Korean students. Fourth, American students demonstrated superior ability in domain-specific creativity compared with the Korean students. Fifth, the need for the class environment in Korea is high on professors attitude & psychological needs ( having a professor who gives positive response even when a student asks uncommon questions ); while the need for it was low in the U.S.. Instead, the high priority rested on real practical needs ( a class that gives practical help in everyday life and a class that focuses on discussion ) in the U.S. than Korea. With these results in mind, this research discuses how to develop creative class environment in the two countries.

Examination of the Domain Decomposition Solvers in COMSOL for a Largescale Problem of APro in Parallel Computing Environment

Hyun Ho Cho,Hong Jang,Dong Hyuk Lee,Jung-Woo Kim 한국방사성폐기물학회 2022 한국방사성폐기물학회 학술논문요약집 Vol.20 No.1

Domain decomposition method (DDM) has been widely employed for the numerical analysis of large-scale problems due to its applicability to parallel computing. DDM divides the modeling domain into a set of subdomains and obtains the entire solution iteratively until the values of each subdomain which are shared with other subdomains, such as boundary values, are converged. Therefore, in general, DDM is a memory-efficient iterative algorithm with inherent parallelism on the geometric level. APro, the process-based total system performance assessment model, aims for simulating the radionuclide transport considering coupled multi-physics phenomena occurring in large-scale geological disposal system, which are inevitably accompanied by huge memory burden. Therefore, DDM is applicable for the large-scale problem of APro and its performance in parallel computing needs to be examined. The DDM solvers provided by COMSOL which constitute APro can be classified into two methods. One is the overlapping Schwarz method that each subdomain overlaps its neighboring domains and the other is the Schur complement method that subdomains are non-overlapping and separated by boundary domains. For the Schwarz method, the additive, hybrid, multiplicative and symmetric methods can be selected according to the solution update scheme. And for the Schur method, the additive and multiplicative ordering options can be chosen for solving Schur complement system. In this study, the calculation efficiency of the DDM solvers in COMSOL and the applicability to the cluster environment were examined. In aspect of efficiency, the memory requirements with different number of subdomains and calculation schemes were compared in a single node. Then, the memory requirements with increasing number of disposal tunnels and deposition holes were investigated in multiple nodes. As a result, on the cluster environment, with the help of distributed memory architecture which enables efficient memory usage, the applicability of DDM solvers to the large-scale problem of APro was confirmed.

본 연구는 역사측정학 방법을 활용하여 한국 현대 소설과 회화 분야의 영역 특성을 밝히고 각 분야의 창조적 명성에 영향을 미치는 발달기 및 성인기의 사회적 환경 요소를 탐구하였다. 먼저 연구 1에서는 두 영역의 경력 표지점을 비교하여 한국 현대 소설 영역이 한국 현대 회화 영역에 비해 새로운 생각과 연합의 빠른 산출과 빠른 산물화가 더 두드러지는 분야임을 밝혀내고 두 영역의 역사적 특성을 바탕으로 이를 설명하였다. 연구 2에서는 연구 1에서 발견한 두 영역의 차이를 바탕으로 출생 순서, 부모 여읨, 어린 시절의 외상적 경험 등 발달기의 사회적 요인과 경쟁, 멘토, 다분야 활동 등 성인기 환경이 창조자의 생애 명성에 미치는 효과를 살펴보았다. 그 결과 어린 시절의 외상적 경험의 영역 일반적인 긍정적 효과와 다분야 활동의 영역 특정적 긍정적 효과, 멘토 수의 영역 특정적 부정적 효과를 확인하였다. 논의를 통해 이러한 결과를 종합하고 그 함의를 논하였다. Using historiometric method, this article analyzed the characteristics of the two creative domains of Korean modern novel writing and modern painting, and explored the socio-developmental conditions that yielded creative outputs in each domain. In study 1, the career landmarks of those two domains were compared and it was discovered that Korean modern novel writing required faster ideation than painting and also its ideation-output ratio was higher than painting. We explained this result in the historical contexts of the two domains. Based on these domain characteristics, in study 2 we tested the effects of social factors in developmental period such as birth order, parental loss and traumatic experience, and the effects of factors in active period such as competition, mentors and versatility to the creators' lifetime eminence. There were domain-general positive effect of traumatic experience in developmental period, domain-specific effect of versatility, and domain-specific negative effect of number of mentors. Finally, we discussed the implications of this study.

기업영역 전문가들의 창의적 특성과 지각된 창의적 환경 요인에 대한 탐색

이선영(Seon Young Lee),민지연(Jin Yeon Min),최차현(Cha Hyun Choi) 한국교육심리학회 2014 敎育心理硏究 Vol.28 No.4

창의성은 개인내적 특성인 동시에 개인이 속한 조직 환경의 영향을 받는다. 본 연구는 개인의 창의적 특성들이 영역과 직무유형에 따라 차이가 나는지 살펴보기 위해 기업영역과 비기업영역의 전문가 297명을 대상으로 창의성진단검사를 실시하였다. 기업영역 전문가들의 경우, 담당하는 직무에 따라 최고경영자, 중간관리자, 실무자로 구분하여 이들의 창의적 특성을 비교, 분석하였다. 더불어 이메일을 통한 후속 설문조사를 실시하여 전문가들이 인식하는 창의성과 실제로 과제를 수행하는 필요한 창의적 능력간의 차이, 창의성을 조장하는 환경 요인에 관하여 살펴보았다. 연구 결과, 전문가들이 속한 영역에 따라 개인의 창의적 특성들은 차이를 보였는데 가령, 기업영역 전문가들의 경우 정교성과 종결저항에서 상대적으로 강점을 보이고 독창성과 추상성에서 취약한 특성을 보인 반면, 비기업영역 전문가들은 그와는 반대로 독창성과 추상성에서 높은 점수, 정교성과 종결저항에서 보다 낮은 점수를 보였다. 기업영역 전문가들의 경우, 직무유형에 따라 상이한 창의적 특성들(예: 최고경영자와 중간관리자는 독창성과 종결저항이 강점, 정교성과 추상성이 약점인 반면, 실무자는 반대의 특성을 보임)을 보여 개인의 창의적 특성이 자신이 속한 영역과 영역 내에서 담당하는 직무에 따라 달라짐을 알 수 있다. 설문조사 결과, 전문가들이 일반적으로 생각하고 있는 창의적 특성들과 업무를 수행하는데 필요한 창의적 특성들 간에 차이가 있는 것으로 드러났고 창의성을 조장하는 환경요인에 대해서도 직급에 따라 다르게 인식하고 있는 것으로 나타났다. 본 연구는 창의성의 영역 및 과제 특수적 속성을 기업조직 전문가들을 주요 대상으로 확인해봄으로써 창의성의 다면적 속성에 대한 올바른 이해가 창의성 증진 및 교육을 위해서 선행되어야 한다는 사실을 상기시키고 있다. 뿐만 아니라 과제수행에 필요한 창의성 및 창의적 특성에 대한 이해, 영역(조직)에서의 창의성 증진을 위해서 개인내적 특성으로서의 창의성뿐만 아니라 과제특성에 적합한 창의적 특성과 환경요인을 고려해야 한다는 점을 재확인함으로써 공교육 현장에서 창의성교육을 계획하고 관련 프로그램을 개발할 때 개인이 잠재적 능력을 보이는 영역과 영역에서 담당하는 과제특성에 기반한 창의적 요소들을 포함할 것을 제안하고 있다. Creativity is not only an intrapersonal characteristic and/or ability but also an outcome of social and environmental systems. Using the figural version of the Torrance Tests of Creative Thinking (TTCT), this study examined creative characteristics, strengths and weaknesses, of individuals in business and non-business domains order to understand how individuals` creativity differs according to the types and characteristics of domains and specific tasks with the domain. About 300 adults who were employed in business and non-business areas (e.g., public service, research and education, arts, medicine, journalism, law) and attended a 16-week creativity education program responded to TTCT. Of these participants, 25 adults responded to a follow-up email survey that examined their perceptions of creative characteristics and abilities needed for overall work environment and specific tasks they were in charge of. Major findings included that individuals` creative strengths and weaknesses differed by the type of domains. On TTCT, businessmen had strengths in elaboration and resistance to premature closure and weaknesses in originality and abstractness of titles, while it was the opposite for those in non-business domains. For businessmen, different creative characteristics were found according to the tasks they were engaged in. For example, CEOs, administrators, and managers had higher scores on originality and closure and lower scores on elaboration and titles, compared to staff members who showed their strengths in elaboration and titles and weaknesses in originality and closure. Perceptions about creative work environment and abilities varied by the individuals who were engaged in different tasks. Also, differences were found between individuals` perceived creativity and actual creative abilities they used for at work. This study proved the multidimensional nature, such as the domain and task specific aspects of creativity and suggested that environmental factors enhancing creativity need to be considered in association with the characteristics of domains and tasks as well as those of individuals.
