  • The cognition of an intrinsic attribute play an important role in the process of theoretical generalization. It is the aim of this paper to study how the theoretical generalization is made. First of all, we suggest the What-if-only-strategy(WIOS) which is the strategy helping the cognition of an intrinsic attribute. And we propose the process of the theoretical generalization that go on the cognitive stage, WIOS stage, conjecture stage, justification stage and insight into an intrinsic attribute in order. We propose the process of generalization adding the concrete process cognizing an intrinsic attribute to the existing process of generalization. And we applied the proposed process of generalization to two mathematical theorem which is being managed in middle school. We got a conclusion that the what-if-only strategy is an useful method of generalization for the proposition. We hope that the what-if-only strategy is helpful for both teaching and learning the mathematical generalization.

  • As an alternative of making students active and independent under the passive learning conditions in school math classes, many researchers have paid much attention to problem posing and done a lot of research on it. Above all, Brown and Walter proposed What I f Not strategy as a means of problem posing. In this strategy, during the process of posing problems, the transformation of their attributes is inevitably made, and so after problem posing, the process is finished by explaining the problem. But only the simple transformation of attributes could pose wrong problems. It suggests that it is very important to recognize the relationship which leads to organic connection between attributes in order to pose the right problem. However, many other studies of problem posing haven't focused on this fact. Thus, this study tried to design a model of problem posing to help recognize inherent knowledge in the problem and then pose the right problem by adding an activity of meaning analysis. We concretely showed a model of problem posing emphasizing the analysis of meaning by means of an example, thereby examining the meaning of the model. This study expects students to have the chance to understand the true meaning of problem posing and to be active learners after all.

  • Are the policies and strategies which weak and small states choose to follow for ensuring their's own security meaningless? Can the fate of weak states be guaranteed only by the neighboring benign strong states and be in certain international relations favoring for them? In this paper, to answer these questions, what kinds of security policies and foreign policies had small states chosen which were in the face of threats of great powers will be examined. Between the two world war, the series of event which took place in central and eastern European countries(CEEc) have been selected to examine the hypothesis and theories of international relations and foreign policies, and at the same time cited as examples of failed foreign policy and security strategy. During interwar periods, CEEc were the prime examples for examining what kind of policies and strategies had the small states chosen over the international relations in which the smalls had to struggle to survive between neighbouring the powers and between the hostiles. Furthermore, for the measures which the smalls had chosen had no effect when the great power threatened military to them, the main purpose of this paper is to examine what was the best choose to depend their survival. For this purpose, in this paper, several strategies which the smalls can choose and the counterfactuals, that is "if the smalls chosen another strategies, they could...", will be examined.

  • When an organization adopts new technology, performance through the technology is expected to be decided depending on attitudes of the members, in that technology produces performance only if the members zealously use it. Therefore, the members need to devote themselves to acquire and use the new technology. This attitude of members is called "IT acceptance will" (Ranarajan et al., 2005), and this research is to examine the effect of an individual's "IT acceptance will" on performance. Thus, this research analyzes what increases IT acceptance will and what effect IT acceptance will has on stress due to uncertainty of an organization-job complexity and role conflict- through new IT adoption. This research conducted a survey from July to September in 2009, targeting employees of government offices and public institutions in Kyunggi and Kyungnam provinces. Then, a total of 370 was collected and the final 344 was selected for our research analysis. As a result, this research found out that personal innovation and client orientation improved an individual's IT acceptance will, which improved performance through new IT adoption. However, the new IT adoption also increased job complexity and role conflict, but negative effects of stress on performance was not found as IT adoption will diminished the stress. Based on this result, this research discussed practical and academic implications and the limitations.

  • The following study specially aims to market platform in the mobile circumstance. The characteristics of customers and infrastructure are handled by market platform under the new media. These characteristics will be revealed based on the unification of organizational structure and interaction of information structure in the relationship marketing. This study investigates what characteristics and impact of infrastructure of Market Platform will affect the cognitive impact on both buyers and sellers to clarify the impact on Perceived integratedness and Interactive Accessibility of the shopping process. Through this investigation, modeling for the impact that new media environment will attract Market Platform will be developed from the investigation of attractiveness of mobile market platform environment. Changes in the technical media environment gave the characteristics of the customer in the market platform, so consumers could involve not only consumed, but also manufactured. Thus, it is possible to increase the attractiveness if market must be able to not only for the convenience of shopping, but also make people to enjoy the experience of value co-creation. In other words, the new media, as a result of affecting the marketing system, mobile market platform is organized on the base of the market communication. Perceived integratedness and Interactive Accessibility, 2 properties of new media increase the co-creation experience and perceived convenience in the market platform of their customers. Therefore, the structure of market platform that enhance the co-creation experience and perceived convenience has higher attractiveness. They create beneficial experience to the customers and productive values to the producers as well.

  • This paper tried to examine the effect of the policy on companies' CSR activities and what kind of a role does CSR have in determining Customer Loyalty in Indonesia. This paper is divided into two parts, the first part is designed to find out whether the Indonesian government law has successfully made the companies perform better CSRs. We do this by using the ICGC Index of the companies registered and comparing their scores before and after the implementation of the policy. We will then use the paired sample t-test to find out if there is an increase in the overall scores of the companies and/or only the natural resource-related companies. The result showed an upward trend in the ICGC scores for all the companies which the Indonesian government law is intended to. In the second part, Manfred Schwaiger's components and parameters of corporate reputation was referred and used on Indonesian customers. We asked participants whether they think natural resource-related companies perform better CSRs and then we also tried to find out what factors really affect their loyalty towards companies or brands by conducting Multiple Regression Analysis. From the 4 factors that we have prepared, which consist of Performance, CSR, Quality and Attractiveness, Quality is the most influential towards determining our survey participants' Customer Loyalty. Surprisingly, CSR is insignificant in directly influencing Customer Loyalty. But, our research did find out that CSR does moderate Quality and Performance in their relationship with Customer Loyalty. Meaning that CSR has no effect in a direct relationship but it can increase the effect of Quality and Performance in determining Customer Loyalty. Unfortunately, CSR has no moderating effect in increasing the effect of Attractiveness towards Customer Loyalty.

  • This study analyzed the results and implications of the industry-university cooperation human resource nurturing process based on the I-O model for the Motion Graphics major and the Global Hotelier major in Baek seok University. In this study, based on the analysis of the human resources training performance through industry-university cooperation in the motion graphics and hotelier fields for 5 years, what kind of efforts were made for successful human resource training, and the level of performance was analyzed and improvement points were suggested. In this study, four strategies were set for successful industry-university-tailored human resource nurturing: student-industry matching through industry participation in education, industry-university integrated education, education quality advancement, and customized education infrastructure construction. As a result of the analysis, customized human resource training should first be developed through industry demand survey and a mirror-type practice room should be built to fit the corporate environment. Second, it was found that it is possible to be individual only if there is an active participation of industry experts throughout the curriculum such as subjects and non-subjects.

  • When a traumatic subject experiences extreme stress, various psychiatric problems, including PTSD, can occur if they do not respond appropriately. In addition, non-war soldiers who experience life-threatening events while serving in the military may experience severe and chronic PTSD symptoms. However, there are still insufficient domestic studies on what traumatic events soldiers are exposed to and how much PTSD symptoms they experience. Therefore, this study provides a method that can be used as basic data for PTSD and psychological support of military service personnel by identifying trends in domestic research. Furthermore, it studies PTSD not only of soldiers but also of 'civilians' who have experienced combat, and provides symptomatic treatment and relief programs to civilians according to the difference in PTSD between general trauma and war trauma. It is expected that these studies will increase military confidence and enable the military to play a leading role in war trauma PTSD research and prevention, treatment and mitigation.

  • Industrial Revolution is a concept and a development that has fundamentally changed our society and economy. Industry 4.0 focuses on the end-to-end digitization of all physical assets and integration into digital ecosystems with value chain partners. At present, we find ourselves at the beginning of this fourth stage, which is characterized by so-called "Cyber-Physical Systems". These systems are a consequence of the far-reaching integration of production, sustainability and customer-satisfaction forming the basis of intelligent network systems and processes. If South Korea ran toward global ICT with the advent of the Fourth Industrial Revolution, North Korea has adhered to a unique Juche science and technology. ICT in South Korea and North Korea seems very difficult to find common interests. However, as seen in the Internet and intranets, information and communication technology can find similarities in many areas than in general science and technology. There are many differences not only in the level of ICT and science and technology but also in the direction. And IT terminology and all technologies are also different. What are we preparing for the unification of North and South Korea? If we look at the science and technology sector at present, there seems to be no systematic preparation by the government. South Korea and North Korea need to be prepared for science and technology cooperation. First, it is necessary to understand the exact situation of North Korea's science and technology. In this study, we will perform research to establish mid and long term plans for revitalization of ICT cooperation between the two Koreas. In this study, we will determine the extent to which the two Koreas utilize ICT based on available ICT capabilities and technologies. To do this, we conducted research to measure and evaluate the ICT development index of North Korea using ICT international index.

  • In this paper, a simple game-theoretic entry deterrence model is developed that integrates both limit pricing and predatory pricing. While there have been extensive studies which have dealt with predation and limit pricing separately, no study so far has analyzed these closely related practices in a unified framework. Treating each practice as if it were an independent phenomenon is, of course, an analytical necessity to abstract from complex realities. However, welfare analysis based on such a model may give misleading policy implications. By analyzing limit and predatory pricing within a single framework, this paper attempts to shed some light on the effects of interactions between these two frequently cited tactics of entry deterrence. Another distinctive feature of the paper is that limit and predatory pricing emerge, in equilibrium, as rational, profit maximizing strategies in the model. Until recently, the only conclusion from formal analyses of predatory pricing was that predation is unlikely to take place if every economic agent is assumed to be rational. This conclusion rests upon the argument that predation is costly; that is, it inflicts more losses upon the predator than upon the rival producer, and, therefore, is unlikely to succeed in driving out the rival, who understands that the price cutting, if it ever takes place, must be temporary. Recently several attempts have been made to overcome this modelling difficulty by Kreps and Wilson, Milgram and Roberts, Benoit, Fudenberg and Tirole, and Roberts. With the exception of Roberts, however, these studies, though successful in preserving the rationality of players, still share one serious weakness in that they resort to ad hoc, external constraints in order to generate profit maximizing predation. The present paper uses a highly stylized model of Cournot duopoly and derives the equilibrium predatory strategy without invoking external constraints except the assumption of asymmetrically distributed information. The underlying intuition behind the model can be summarized as follows. Imagine a firm that is considering entry into a monopolist's market but is uncertain about the incumbent firm's cost structure. If the monopolist has low cost, the rival would rather not enter because it would be difficult to compete with an efficient, low-cost firm. If the monopolist has high costs, however, the rival will definitely enter the market because it can make positive profits. In this situation, if the incumbent firm unwittingly produces its monopoly output, the entrant can infer the nature of the monopolist's cost by observing the monopolist's price. Knowing this, the high cost monopolist increases its output level up to what would have been produced by a low cost firm in an effort to conceal its cost condition. This constitutes limit pricing. The same logic applies when there is a rival competitor in the market. Producing a high cost duopoly output is self-revealing and thus to be avoided. Therefore, the firm chooses to produce the low cost duopoly output, consequently inflicting losses to the entrant or rival producer, thus acting in a predatory manner. The policy implications of the analysis are rather mixed. Contrary to the widely accepted hypothesis that predation is, at best, a negative sum game, and thus, a strategy that is unlikely to be played from the outset, this paper concludes that predation can be real occurence by showing that it can arise as an effective profit maximizing strategy. This conclusion alone may imply that the government can play a role in increasing the consumer welfare, say, by banning predation or limit pricing. However, the problem is that it is rather difficult to ascribe any welfare losses to these kinds of entry deterring practices. This difficulty arises from the fact that if the same practices have been adopted by a low cost firm, they could not be called entry-deterring. Moreover, the high cost incumbent in the model is doing exactly what the low cost firm would have done to keep the market to itself. All in all, this paper suggests that a government injunction of limit and predatory pricing should be applied with great care, evaluating each case on its own basis. Hasty generalization may work to the detriment, rather than the enhancement of consumer welfare.
