Composite research and development in Korea
No full textThe recent research and development activities of some laboratories working on composite materials in universities (KAIST, Seoul National Univ., Postech, Gyeongsang National Univ.), research institutes (KIMM, KARI), and companies (Hankuk Fiber, DACC) are introduced in this article. Their activities cover a broad range of research and development fields in composite materials: design and fabrication; processing technology; structural analysis; characterization of composite materials; NDE; fiber optic structures; damage detection; health monitoring; smart structures and so on. These technologies will be increasingly used in various fields and the development of these technologies will play an important role in future industries.The author acknowledges the assistance of several university laboratories, the
composite group in KIMM, and the aircraft division of KARI, Hankuk Fiber, and DACC
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Uncertainty and Delay in Bargaining.
No full textThis paper investigates the relationship between uncertainty and delay of agreement in the one-sided offer bargaining model with two-sided uncertainty where the seller makes offers. The author constructs a weak stationary equilibrium in which different types of the seller charge different prices in every period. The author completely characterizes the separating equilibrium by three regularity conditions, and shows that the time interval between offers converges to zero, the seller's initial price offer in a separating equilibrium converges with probability one to the lowest valuation of the buyer if and only if the gain from trading is common knowledge.

Viscous effects on the resonance of a slotted wind tunnel using finite elements
No full textModel flutter and oscillatory airload measurements will be affected by coupling with an acoustic vibration mode when the model frequency is near a tunnel resonance frequency. Widmayer, Clevenson, and Leadbetter conducted some experiments to measure the oscillatory aerodynamic forces and moments acting on a rectangular wing. The test results were in considerable error near the tunnel resonant frequency. Therefore, the authors want to predict the wind-tunnel resonant frequency accurately. The authors confine their concern to the wind tunnel that does not have a plenum chamber to simplify the problem, and they discuss the case in which the slot width is very small to consider viscosity effects.This research was performed under NASA Grant NGL-05-

Dynamics of Network Formation Processes in the Co-Author Model
No full textThis article studies the dynamics in the formation processes of a mutual consent network in game theory setting: the Co-Author Model. In this article, a limited observation is applied and analytical results are derived. Then, 2 parameters are varied: the number of individuals in the network and the initial probability of the links in the network in its initial state. A simulation result shows a finding that is consistent with an analytical result for a state of equilibrium while it also shows different possible equilibria.Dynamics, Network, Game Theory, Model,Simulation, Equilibrium, Complexity
Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
A Comparative Study on Publishers’ Adult Book Clubs Marketing Strategies in the UK and South Korea
No full textThis dissertation aims to produce useful advice for publishers who are planning to organise their own reading group. Particularly, I focus on publishers’ book club marketing strategies which are expected to build a strong relationship with consumers and maximize their marketing efficiency.
This research mainly observed publishers’ adult book clubs in the UK and South Korea. These countries have different market situations and historical context, and therefore each publisher performs various marketing activities within their individual tactics and goals. In order to discover useful recommendations which can be mutually beneficial for improving the book club marketing, I analyse similarities and differences of the overall book club trends between these countries.
In Britain, publishers commonly tend to cooperate with existing, already well-organised reading groups, rather than organising their own new book clubs. However, there are several successful publishers’ book clubs operating on social media as well. I mainly observed three publishers’ book clubs: Hurricane Book Club (Pan Macmillan), Page Turners (Penguin Books) and Virago Modern Classic Book Club (Virago). I also interviewed the marketers who are in charge of these book clubs. I found that most book club marketing strategies are functioning effectively in the whole marketing chain. Common book club activities in Britain such as social media campaigns, author events and promotional materials are very well-integrated with the ordinary marketing and PR plans. The book clubs give additional opportunities to promote their titles, and can target specific audiences who voluntarily belong to their book club. This helps publishers to minimise their effort and budget on marketing.
In South Korea, although private reading groups have been fewer than in Western countries, these are recently getting popular with the younger generation. The boom of reading groups met the needs of Korean publishers that had been seeking a method to reduce marketing costs. Furthermore, book clubs which can build a consumer relationship without retailers strongly attracted publishers. Over the past few years, several publishers started organising their own book clubs. I mainly analysed three publishers’ book clubs: Minum Book Club (Minumsa), Book Club Munhakdongne (Munhakdongne) and Chaegingnundang (Changbi) and also interviewed three marketers who are in charge of these book clubs. The most distinctive feature throughout the overall Korean trend is that a paid membership model is thriving. Based on a large budget from their annual fee, publishers could provide numerous giveaways and events for their members exclusively. These book club activities reinforced loyalty of their brands. Furthermore, several gigantic book clubs drew huge attention from media and the public, so their brand awareness is enhanced as well.
The analysis of the book club activities potentially provides useful marketing advice for publishers in both countries. British publishers might consider the paid membership which can provide rich giveaways and events without a huge financial burden. This membership model also gives more opportunities to build a solid brand reputation. Publishers in South Korea should consider how they design the book club activities to harmonise with the whole marketing plan of their company in order to manage the heavy workload they put into their book club. They also need to put more effort into concentrating on generating a buzz about the titles they want to highlight
