Background: Research investigating the relationship between latitude and network specialization plant-pollinator networks present conflicting results. While some studies indicate a positive link between latitude and network specialization, particularly in tropical regions, others suggest contradictory trends, with specialization declining towards lower latitudes. These studies underscore the intricate nature of ecological specialization in plant-pollinator networks and the need for further studies in this field to gain a more nuanced understanding of the underlying mechanisms driving these patterns. In this study, we explore the relationship between plant-pollinator network specialization and latitude using a global dataset comprising 93 plant-pollinator networks. Results: Our analysis revealed a significant relationship with latitude mostly in the Southern Hemisphere, particularly concerning metrics such as connectance and nestedness. However, notably, we found no association with H2, a metric immune to the size, shape, or sampling effects of the network and considered highly suitable for measuring network specialization in both Hemispheres. Conclusions: The absence of latitudinal trends in network specialization (H2) in both Hemispheres in this study imply that the mutual attraction between plants and pollinators remains relatively stable across various latitudes. Our comparison with prior research highlights the diversity of conclusions regarding how latitude influences plant-pollinator networks. While our results are consistent with certain studies, indicating no direct impact of latitude on network specialization, discrepancies persist.

ICT(information and communication technology) has played a pivotal role in the world economy, and the out look for ICT has improved markedly. One of the noticeable characteristics in the ICT sector Is the global rationalization of its technology and service. Specialization on the specific ICT capability is a pressing problem for many countries. Along the line of classical innovation cluster and network studies, this paper suggests a way to find and analyze the role of core technologies on the ICT network First, technology network is constructed by using patent citation data from USPTO. Then, a couple of cluster is generated by K-means clustering technique. Finally, brokerage analysis is applied to manifest the role of principal technologies. The network visualization and some stylized facts on dynamics are briefly given altogether Based on the role and relationship of technologies across clusters, it is expected that this research could contribute to the ICT cluster formation and the vision-making for ICT specialization at the viewpoint of technology Policy.

Joint research on software, electronic engineering, computer engineering, and financial engineering and the use of ICT knowledge through network formation play an important role in strengthening science and technology-based innovation capabilities and facilitating the development and production process of products using new technologies. For the purpose of this study, I would like to strategically propose ICT specialized education in the 4th industrial revolution. To this end, the ICT specialization model, ICT specialization strategy analysis, and ICT specialization operation and effect were explored to establish ICT specialization strategies centered on software, electronic engineering, computer engineering, and financial engineering in the era of super-intelligence, hyper-connected, and hyper-convergence. Secondly, a roadmap for detailed promotion tasks related to efficient ICT characterization based on core strategies, detailed promotion tasks, and programs was proposed, focusing on talent related to ICT characterization. Thirdly, we would like to propose a reorganization of the academic structure and organization related to ICT characterization. Finally, we would like to propose the establishment of a future-oriented education system related to ICT specialization based on the advanced education and research environment.

Joint collection and sharing of specialized academic resources among academic libraries will not only promote academic research at universities in general but also further diversification and concentration process of academic libraries. For that both the government and universities should make concerted policy efforts to fortify individual characteristics of each academic library. This study proposes two concrete plans to build a national information management system comprising the specialized resources of academic libraries. One is to utilize the existing cooperative network of Korea Education & Research Information Service(KERIS) as a national hub for information exchange, and the other is to activate various regional or subject-based committees to encourage subject-oriented specialization of university libraries.

This study analyzed the centrality of the GVCs network and the value-added-based production structure of the electrical and electronic industries using ADB-MIRO and social network analysis methods. According to the analysis, the centrality and power of the GVSc intermediate goods network were differentiated into China, the United States, and the EU due to the advancement of industrial structure in Asia. In the 2000 network, the United States and Japan had a very strong influence in all aspects, including connectivity and strength. However, in 2017, China's power index rose to number one among 62 countries in the network. Furthermore, this study presented strategic implications of the Korean electrical and electronic industries to respond to the reorganization of GVSs based on the analysis results.

This paper proposes strategy development to improve the management of Multicultural Family Support Centers by analyzing four Multicultural Family Support Centers (MFSCs) in Chungcheongnam-do. The research was conducted from September 2012 to January 2013. Future directions for the four MFSCs are established based on a SWOT analysis on both the internal and external environments of the centers. Various strategic directions for the four MFSCs were identified based on these analyses. For center A (urban type, college contract type), the strategic directions included the specialization strategy, systemization strategy, empowerment strategy, standardization strategy, and achievement maximization strategy. The strategic directions for center B (urban-rural combined type, social welfare center contract type) included the improvement of multiculture awareness, specialization strategy, human resource development strategy, and networking strategy. For center C (farming and fishing community type, direct management type by local authority), the strategic directions included the specialization strategy, activation strategy, qualification strategy, and networking strategy. For center D (farming and fishing community type, social welfare center contract type), the strategic directions included the specialization strategy, business standardization strategy, human resource development strategy, and network expansion strategy. The suggested management strategy development for the four MFSCs can provide implications for the management of MFSCs in other areas in Korea.

The purpose of this study is to investigate the characteristics of menswear designers and the process of becoming a menswear designer expert through qualitative evaluation and statistical analysis. This study used ten menswear designers with more than fifteen years of experience. After going through the University P IRB approval process, a semi-structured questionnaire was prepared and individual in-depth face-to-face or video interviews were conducted from March 1, 2020 to March 31, 2021. From this qualitative study examining the characteristics of menswear designer job experience, four key themes were found: the competence required for the professionalization process of menswear designers; the creative sensibility of menswear designers; the uniqueness of menswear designers' work; basic education required for menswear designers. In order to find additional meaningful implications using the visual analysis technique, we examined the primary vocabulary using the word cloud technique and examined the relationship between the vocabulary using the network graph. In the follow-up study, we expect to develop a material-oriented education program for new menswear designers and to resolve the limitations of the study, targeting a small number of experienced menswear designers.

This paper discusses a new algorithm, the PAPANET (Pivot And Probe Algorithm for NETwork optimization), for solving linear, capacitated linear network flow problem (NPs), PAPANET is a variation and specialization of the Pivot And Probe Algorithm (PAPA) developed by Sethi and Thompson, published in 1983-1984. PAPANET first solves an initial relaxed NP (RNP) with all the nodes from the original problem and a limited set of arcs (possibly all the artificial and slack arcs). From the arcs not considered in the current relaxation, we PROBE to identify candidate arcs that violate the current solution's dual constraints maximally. Candidate arcs are added to the RNP, and this new RNP is solved to optimality. This candidate pricing procedure and pivoting continue until all the candidate arcs price unfavorably and all of the dual constraints corresponding to the other, so-called noncandidate arcs, are satisfied. The implementation of PAPANET requires significantly fewer arcs and less solution CPU time than is required by the standard network simplex method implementation upon which it is based. Computational tests on randomly generated NPs indicate that our PAPANET implementation requires up to 40-50% fewer pivots and 30-40% less solution CPU time than is required by the comparable standard network simplex implementation from which it is derived.
