  • This paper focused on the level of managerial centralization on chief executive officer (CEO) as a factor to affect the shared growth activities of corporate. As service corporations are becoming active in shared growth activities recently, this paper thus used CEO. Pay Slice (CPS) information to measure the level of managerial centralization on CEO of service corporation and tested the influence of the level of managerial centralization on whether shared growth activities are executed and the level of such activities respectively. The result of test shows that companies with high managerial centralization on CEO are more passive toward shared growth activities than those without such centralization. This can be interpreted that a CEO with more powerful influence may consider shared growth activities as to be negative and take a passive attitude to them. On the other hand, such result was supported by additional analysis with companies committing shared growth activities as well. This paper is expected to contribute to bring about interest on shared growth activities as the gap between major companies and small and medium sized companies is currently expanding in terms of operating profit ratio and even salary of employees.

  • Overlay routing has emerged as a promising approach to improve reliability and efficiency of the Internet. The key to overlay routing is the placement and maintenance of the overlay infrastructure, especially, the selection and placement of key relay nodes. Spurred by the observation that a few relay nodes with high betweenness centrality can provide more optimal routes for a large number of node pairs, we propose a resilient routing overlay network construction method by introducing Super-Relay nodes. In detail, we present the K-Minimum Spanning Tree with Super-Relay nodes algorithm (SR-KMST), in which we focus on the selection and connection of Super-Relay nodes to optimize the routing quality in a resilient and scalable manner. For the simultaneous path failures between the default physical path and the overlay backup path, we also address the selection of recovery path. The objective is to select a proper one-hop recovery path with minimum cost in path probing and measurement. Simulations based on a real ISP network and a synthetic Internet topology show that our approach can provide high-quality overlay routing service, while achieving good robustness.

  • This research conducted a before/after naturalistic field experiment, with the early Arab Spring as the treatment. Compared to before the early Arab Spring, after the observation period the associations became stronger among the Web terms: 'Jihad, Sharia, innovation, democracy and civil society.' The Western concept of civil society transformed into a central Islamist ideological component. At another level, the inter-nation network based on Jihad-weighted Web hyperlinks between pairs of 46 Muslim Majority (MM) nations found Iran in one of the top two positions of flow betweenness centrality, a measure of network power, both before and after early Arab Spring. In contrast, Somalia, UAE, Egypt, Libya, and Sudan increased most in network flow betweenness centrality. The MM 'Jihad'-centric word co-occurrence network more than tripled in size, and the semantic structure more became entropic. This media "cloud" perhaps billowed as Islamist groups changed their material-level relationships and the corresponding media representations of Jihad among them changed after early Arab Spring. Future research could investigate various rival explanations for this naturalistic field experiment's findings.

  • Purpose: This study analyzed research trends related to childhood and adolescent cancer survivors (CACS) using word co-occurrence network analysis on studies registered in the Korean Citation Index (KCI). Methods: This word co-occurrence network analysis study explored major research trends by constructing a network based on relationships between keywords (semantic morphemes) in the abstracts of published articles. Research articles published in the KCI over the past 10 years were collected using the Biblio Data Collector tool included in the NetMiner Program (version 4), using "cancer survivors", "adolescent", and "child" as the main search terms. After pre-processing, analyses were conducted on centrality (degree and eigenvector), cohesion (community), and topic modeling. Results: For centrality, the top 10 keywords included "treatment", "factor", "intervention", "group", "radiotherapy", "health", "risk", "measurement", "outcome", and "quality of life". In terms of cohesion and topic analysis, three categories were identified as the major research trends: "treatment and complications", "adaptation and support needs", and "management and quality of life". Conclusion: The keywords from the three main categories reflected interdisciplinary identification. Many studies on adaptation and support needs were identified in our analysis of nursing literature. Further research on managing and evaluating the quality of life among CACS must also be conducted.

  • Objective: This study aimed to analyze the counseling contents of daycare center teachers by using text mining and semantic network analysis methods to find the necessary support directions for daycare teachers and to improve the quality of child-care. Methods: Five hundred thirteen cases of counseling recorded on the open bulletin board of online counseling (Naver Bands for Nursery Teacher Counseling) were collected, and frequency analysis, centrality solidarity analysis, and machine learning-based topic analysis were conducted using the NetMiner4.3 program. Results: First, 'teacher-to-child ratio' was highest in the frequency. Second, 'colleagues' were all high in all centrality analysis. Third, machine learning-based topical analysis shows that the topics were categorized as subjects about 'childcare and education', 'working environment that supports professional development' and 'working condition', and among them, 'first-time teacher concerns' accounted for 44% of the total counseling content. Conclusion/Implications: This study implied that it is necessary to provide high-quality child-care and education to infants by lowering the 'teacher-to-child ratio', and a systematic program is needed to help improve effective communication skills in interpersonal relationships such as between parents, fellow teachers, and principals. In addition, self-development and efforts to improve teachers expertise should be prioritized in order to improve infant care quality and quality of teachers.

  • This essay "Twain's Contestation of Emersonian Transcendental Manhood in Huckleberry Finn" explores how Mark Twain's Adventures of Huckleberry Finn (1884) manifests his postwar contestation of Ralph Waldo Emerson's transcendental manhood that endorses the dogmatic, egocentric, and decorporealized position of the Cartesian subject, who believes his being's unity, elevation, and centrality through his fantasy of possessing direct access to divine truth. The connection between Emerson and Twain is based not on Emerson's influence on Twain but on their common interest in American landscape as a site for the redefinition of manhood and masculinity. I examine different types of manhood in their association with nature in Huckleberry Finn by comparing them with the two fundamental concepts of Emerson's philosophy: "a true man" in "Self-Reliance" (1841) and transparent eyeball vision in Nature (1836). Twain's use of Huck's ambivalent position-his centrality as a protagonist in the novel in spite of his marginality in society-renegotiates Emerson's valorization of nonconformity, wholeness, and nonchalance as the characteristics of both boyhood and "a true man," Emerson's term for the ideal individual in "Self-Reliance." I also read Twain's satire of two different types of masculine characters-Bob and the Child of Calamity, boatmen of the Southern frontier, and Colonel Grangerford, patriarch of a Southern aristocratic family-as Twain's denouncement of the antebellum desire for transcendental vision, which Emerson crystalizes into his notion of transparent eyeball in Nature.

  • 본 연구는 구조적 정의에 의한 학술 용어 사전 데이터베이스 구축을 위해 학술용어의 의미관계 형성에 미치는 요인이 무엇인지를 찾아내고 이러한 요인이 어떠한 영향을 미치고 있는지를 밝히고자 하였다. 이를 위해 2007년부터 2011년 사이에 한국연구재단 등재학술지에 등재된 학술논문에서 학술논문 주제어를 추출하여 이를 대상으로 주제복합성, 언어 네트워크 특성, 출현빈도, 출현패턴을 분석하고 구축된 STNet의 의미관계 형성정도인 용어의 의미적 연결관계 노드의 수와 유형의 수와의 영향 관계를 살펴보았다. 가설 검증을 통해 구조적 학술용어사전의 구축에 있어 의미관계 형성정도에 주요한 영향을 미치는 요인으로 매개 중심성, 출현빈도, 구조적 공백성의 효과크기라는 것을 알 수 있었다. 그리고 용어의 중요성은 일반적으로 알려진 출현빈도를 통한 방법 외에도 연결정도 중심성, 근접 중심성, 매개 중심성, 위세 중심성과 같은 측정방법에 따라서도 판단할 수 있음을 확인하였다. 또한 주제복합성은 직접적으로 의미관계 형성정도에 영향을 미치지는 않지만 용어의 근접 중심성에 영향을 미치기 때문에 크게 4가지의 요인을 고려하여 용어를 선정할 경우 의미관계 형성정도는 높아질 수 있는 것으로 파악 되었다. 본 연구의 결과는 지금까지 용어를 선정하는 프로세스의 주된 방법론인 용어의 출현빈도를 활용하는 방법 이외에도 용어 네트워크상에서의 용어의 위치나 주제복합성 같은 방법론을 적용하여 용어를 선정할 수 있다는 것을 보여준다. 따라서 전문용어 사전을 구축할 때 용어의 네트워크에서의 매개 중심성, 출현빈도, 구조적 공백성의 효과크기, 용어의 주제복합성을 면밀히 판단하여 다각도로 용어를 선정할 경우 전문용어 사전의 질적인 향상과 완성도가 높아질 것을 기대할 수 있다.

  • 사회 문화 전반에 걸쳐 각종 체계를 네트워크로 연결하여 정보를 공유하고 다양화하려는 시도가 지속적으로 이루어지고 있다. 이러한 변화에 부합하여, 군 전쟁 수행방식은 개별 전투체계를 기반으로 하는 플랫폼 중심 전쟁(Platform Centric Warfare)에서 정밀 화력 및 네트워크를 기반으로 하는 네트워크 중심 전쟁(Network Centric Warfare)으로 개념이 바뀌고 있다. 더불어, 이러한 네트워크로 연결된 체계들을 효율적으로 운영하여 최대의 효과를 달성하기 위한 노력이 지속적으로 이루어지고 있다. 그러나 이러한 분야의 연구는 민간분야에서는 활발히 진행 중이나, 아직까지 군 네트워크 체계 분석에 대한 연구는 상대적으로 미흡한 실정이다. 따라서 본 논문에서는 최근 사회, 과학적으로 폭 넓게 활용되고 있는 소셜 네트워크 분석(Social Network Analysis)방법을 군 네트워크 체계에 적용하여 네트워크 구조적 영향력 요소를 규명한다. 이때 지휘통제시간을 효과 측정수단으로 분석하여, 이와 소셜 네트워크 분석요소와 상관관계를 규명한다. 본 연구를 통해 향후 발전적인 네트워크 구성을 위한 네트워크 영향력 요소를 식별하였다는데 가치가 있다.
