Research on regional innovation has recently emphasized the significance and necessities of global networks. However, theoretical arguments have not provided the answers for how global networks are actually formed and work, and the related discussions have not been cohesive while introducing separate concepts originated from diverse disciplines without connecting them with each other. This paper intends to critically review theoretical concepts on spatialities of regional innovation networks and demonstrate limits of each concept, arguing that a synthetic perspective is necessary for understanding how global innovation networks work. The author introduces, specifically, the concept of transnational ethnic communities, which has been recently given much attention to investigate global innovation networks, and provide its theoretical and policy implications.

Purpose: The purpose of this study was to analyze the topic trend of domestic simulation nursing education research using text network analysis(TNA). Methods: This study was conducted in four steps. TNA was performed using the NetMiner (version 4.4.1) program. Firstly, 245 articles from 4 databases (RISS, KCI, KISS, DBpia) published from 2008 to 2018, were collected. Secondly, keyword-forms were unified and representative words were selected. Thirdly, co-occurrence matrices of keywords with a frequency of 2 or higher were generated. Finally, social network-related measures-indices of degree centrality and betweenness centrality-were obtained. The topic trend over time was visualized as a sociogram and presented. Results: 178 author keywords were extracted. Keywords with high degree centrality were "Nursing student", "Clinical competency", "Knowledge", "Critical thinking", "Communication", and "Problem-solving ability." Keywords with high betweenness centrality were "CPR", "Knowledge", "Attitude", "Self-efficacy", "Performance ability", and "Nurse." Over time, the topic trends on simulation nursing education have diversified. For example, topics such as "Neonatal nursing", "Obstetric nursing", "Pediatric nursing", "Blood transfusion", "Community visit nursing", and "Core basic nursing skill" appeared. The core-topics that emerged only recently (2017-2018) were "High-fidelity", "Heart arrest", "Clinical judgment", "Reflection", "Core basic nursing skill." Conclusion: Although simulation nursing education research has been increasing, it is necessary to continue studies on integrated simulation learning designs based on various nursing settings. Additionally, in simulation nursing education, research is required not only on learner-centered educational outcomes, but also factors that influence educational outcomes from the perspective of the instructors.

The impact of output conductance (g_o) on the short-circuit current-gain cut-off frequency (f_T) in In_0.8Ga_0.2As high-electron-mobility transistors (HEMTs) on an InP substrate was investigated. An attempted was made to extract the values of f_T in a simplified small-signal model (SSM) of the HEMTs, derive an analytical formula for f_T in terms of the extrinsic model parameters of the simplified SSM, which are related to the intrinsic model parameters of a general SSM, and verify its validity for devices with L_g from 260 to 25 nm. In long-channel devices, the effect of the intrinsic output conductance (g_oi) on f_T was negligible. This was because, from the simplified SSM perspective, three model parameters, such as g_{m_ext}, C_{gs_ext} and C_{gd_ext}, were weakly dependent on g_oi. However, in short-channel devices, g_oi was found to play a significant role in degrading f_T as L_g was scaled down. The increase in g_oi in short-channel devices caused a considerable reduction in g_{m_ext} and an overall increase in the total extrinsic gate capacitance, yielding a decrease in f_T with g_oi. Finally, the results were used to infer how f_T is influenced by g_oi in HEMTs, emphasizing that improving electrostatic integrity is also critical importance to benefit fully from scaling down L_g.

This paper provides a critical perspective in historic conservation with reference to Hanok (Korean Traditional Courtyard houses) built in central Taegu city, Korea. These Hanok houses began to emerge in the 1920s near the city castle during the Japanese occupation. The houses were shrewdly crafted into a small site in an urban context. Towards the end of 1980s, the demand for urban regeneration arose due to dilapidation of the timber structure and fire safety. Proposals were made to redevelop the areas, but they did not progress past this point. No attempts were made for conservation either and the urban fabric disintegrated continuously. The area is now largely unattended for conservation or redevelopment. This research intends to create an historic account of Hanok in an urban context for its enduring characteristics and historicity as charm and merit that deserve careful apprehension and conservation. This paper suggests that conservation not only serves to gentrify the cultural disruption of the early 20th century but also contributes towards urban regeneration.

The purpose of this paper is to disclose the characteristics of SNS service platform in the perspective of 'dispositif'. To achieve this I extended Foucault's concept of 'dispositif' to the Internet and service platform of Google, Facebook. The platform dispositif is a complex of the interface services for the users, collection of data produced by users and the control of them. These three aspects are combined in the service platform modifying their modes in terms of time and space. This study would provide a critical approach toward the appropriation and control of user activities based upon platform.

With the pervasiveness of digital environment and expansion of new media, ICT (Information and Communication Technology) leads the role of consumer to change from a passive customer into an active co-producer. As customer participation in the fashion industry increases, this study attempts to explore the cases of customer participation as a co-producer in fashion industry through analyzing business models of companies, including Threadless, Blank label, Cut on Your Bias, Acustom Apparel, Thinkgivers. The results show that customer participation is mainly facilitated through design participation in fashion industry, with different level of participation and IT as well as different contribution target. Compared to the past, consumer’s preference is reflected through participation before the stage of production. Results indicate three main characteristics of customer participation in fashion industry. First, value co-creations using customer experiences and understanding customer needs are important. Second, active online communication among customers are critical. Third, it is important to ensure customer’s own item. From a customer perspective, participation enables them to purchase their own distinctive product and offers exciting experience and satisfaction over the production processes, and compensation can be used to increase customer participation. On the other hand, companies using customer participation can take advantage of cost reduction in product development, inventory, and marketing. Customer participation, as a win-win strategy for business and consumer, is expected to expand further in the future with the development of ICT.

Dynamic aeroelastic behavior of structurally nonlinear Joined Wings is presented. Three configurations, two characterized by a different location of the joint and one presenting a direct connection between the two wings (SensorCraft-like layout) are investigated. The snap-divergence is studied from a dynamic perspective in order to assess the real response of the configuration. The investigations also focus on the flutter occurrence (critical state) and postcritical phenomena. Limit Cycle Oscillations (LCOs) are observed, possibly followed by a loss of periodicity of the solution as speed is further increased. In some cases, it is also possible to ascertain the presence of period doubling (flip-) bifurcations. Differences between flutter (Hopf's bifurcation) speed evaluated with linear and nonlinear analyses are discussed in depth in order to understand if a linear (and thus computationally less intense) representation provides an acceptable estimate of the instability properties. Both frequency- and time-domain approaches are compared. Moreover, aerodynamic solvers based on the potential flow are critically examined. In particular, it is assessed in what measure more sophisticated aerodynamic and interface models impact the aeroelastic predictions. When the use of the tools gives different results, a physical interpretation of the leading mechanism generating the mismatch is provided. In particular, for PrandtlPlane-like configurations the aeroelastic response is very sensitive to the wake's shape. As a consequence, it is suggested that a more sophisticate modeling of the wake positively impacts the reliability of aerodynamic and aeroelastic analysis. For SensorCraft-like configurations some LCOs are characterized by a non-synchronous motion of the inner and outer portion of the lower wing: the wing's tip exhibits a small oscillation during the descending or ascending phase, whereas the mid-span station describes a sinusoidal-like trajectory in the time-domain.

The purpose of this study is to suggest the assessment method for PO6(teamwork) and PO7(communication skill), one of the most important assessment items in engineering accreditation. In this paper, we used the assessment criteria of Rubric, to empirically measure the teamwork and communication skill. Teamwork and communication skill (PO6, PO7) are the most critical social competences in modern society. Numerous studies on education showed that teamwork and communication skill can be enhanced through learning. We, therefore, need to investigate teamwork and communication skill in terms of education. However, research on the assessment method of the engineering accreditation, based on educational view is scarce. In this study, we suggest the assessment criteria of Rubric for PO6 and PO7 with the perspective of the education. We also tried to apply the developed criteria to the related subjects.

Purpose: This study aimed to explore and compare the knowledge structure of pain management nursing research, between Korea and other countries, applying a text network analysis. Methods: 321 Korean and 6,685 international study abstracts of pain management, published from 2004 to 2017, were collected. Keywords and meaningful morphemes from the abstracts were analyzed and refined, and their co-occurrence matrix was generated. Two networks of 140 and 424 keywords, respectively, of domestic and international studies were analyzed using NetMiner 4.3 software for degree centrality, closeness centrality, betweenness centrality, and eigenvector community analysis. Results: In both Korean and international studies, the most important, core-keywords were "pain," "patient," "pain management," "registered nurses," "care," "cancer," "need," "analgesia," "assessment," and "surgery." While some keywords like "education," "knowledge," and "patient-controlled analgesia" found to be important in Korean studies; "treatment," "hospice palliative care," and "children" were critical keywords in international studies. Three common sub-topic groups found in Korean and international studies were "pain and accompanying symptoms," "target groups of pain management," and "RNs' performance of pain management." It is only in recent years (2016~17), that keywords such as "performance," "attitude," "depression," and "sleep" have become more important in Korean studies than, while keywords such as "assessment," "intervention," "analgesia," and "chronic pain" have become important in international studies. Conclusion: It is suggested that Korean pain-management researchers should expand their concerns to children and adolescents, the elderly, patients with chronic pain, patients in diverse healthcare settings, and patients' use of opioid analgesia. Moreover, researchers need to approach pain-management with a quality of life perspective rather than a mere focus on individual symptoms.

Record continuum is a theory providing the basis for archival science in the paradigm shift to the electronic record environment. However, critical analysis of it has been hardly performed so far, as it is still in development, and its core is a new perspective on records different from the life cycle model. Therefore, for further understanding of the significance and limitations of record continuum in the electronic record environment and performance of more in-depth theoretical development, an analysis of the meaning and nature of records contained in record continuum logic is essential. Given that record continuum does not define a record separately, the meaning and nature of records it contains in the recent electronic record environment are examined through the analysis of axis and dimension in a record continuum model.
