Many game designers suggested that if players got many objective performance, they could have a fun experience while playing the MMORPG. Does a quantity of objective performance lead to player's fun experience in the MMORPG? According to the Equity Theory, the reason of players getting fun experience is not only that players get reasonable objective performances as many as efforts of theirs but also that amount of their objective performances were same as others. This study analysed that the equity of objective performances would have an effect on the player's fun experience. The results were that the equity of objective performances produced an effect on the players' behavioral intention, flow experience, and cognitive performance. Hence if game designers want that players are interested in the online game playing, they have to support the equity of objective performance to players.

Recent studies focus on how open innovation strategies affect innovation in enterprises, but lack research related to the forms of openness. There is also a paradox that an entity should open up for open innovation but also protect its innovation. In this regard, the need for research on innovation protection has expanded. Therefore, this study looked at the effect of the form of openness on product innovation, and explored how the relationship between the form of openness and product innovation depends on the appropriation mechanisms. This study used data from the Korean Innovation Survey(KIS), which was developed and distributed by the OECD. The main findings of this study are summarized as follows. First, the forms of openness has a positive effect on product innovation. Specifically, external search has had a positive impact on exploitative innovation, and collaboration has shown to have a positive impact on exploratory innovation. Second, the appropriation mechanisms has a positive moderating effect on the relationship between the forms of openness and product innovation. Specifically, it was shown that formal appropriation mechanisms had a positive effect on the relationship between external search and product innovation, and that informal appropriation mechanisms had a positive effect on the relationship between collaboration and exploratory innovation. This study is expected to contribute to: First, this study has divided the forms of openness into external search and collaboration, unlike the existing method, and thus identified the type of product innovation and the appropriation mechanisms and forms of openness by identifying the impact on product innovation. Second, depending on the characteristics of the appropriation mechanisms, it was identified that it had the moderating effect on the forms of openness and the relationship of product innovation, so that depending on the type of openness and the type of product innovation, the type of appropriation mechanisms more suitable was identified.

Total 183 private forest owners in Chungnam-Do were surveyed in order to analyse the attitudes toward cooperative forest management and to find out the relationship of the attitudes with such socio-economic variables as owners' socio-economic status(SES), age and educational level. Major findings of the study are summarized as follows:- 1. Only 17.5 percent of the owners regards the cooperative management as a desirable alternative for the management of private forests. Significant difference of their attitudes is recognized only among the classes of the educational level. 2. About one-third of the owners wishes to participate to a cooperative, if established. The owners' intention of participating is positively related to the degree of S.E.S. and educational level, but negatively associated with that of age variable, and the differences among the classes of all variables are significant at the 0.01 or 0.05 levels. 3. More than half of the owners desires to have limited cooperatives, in which the members themselves manage their forest land with some management aspects being handled by the cooperative such as procurement of seedlings, protection measures, and marketing. The difference of responses among the classes of educational level is significant at the 0.01 level. 4. The owners, who agree with the idea of voluntary membership in the cooperative, are about 45 percent of the total. Significant difference is found only among the classes of the S.E.S. variable. 5. Nearly 60 percent of the owners wants to have self-help cooperative organizations. Significant difference of responses is recognized only among the classes of the age variable.

The Yangsan Forest Management Station (YFMS) of Korean German Forest Management Project (KGFMP), working with the 6 legal villages of Uljugun, Kyongnam, led the forest owners in the area to organize the Forest Management Cooperative (FMC) voluntairily for improvement of private forest management and fostered it as a model from May 1975 to Apr. 1984. YFMS sent out FMC a forest manager as a forestry expert carrying out the leading extension program at the equal position with forest owners and gave FMC financial, administrative and technical assitances. During the 6 years from 1977 to 1982, 4 FMC were founded and are being operated democratically. 228 forest owners have taken the membership of their own free will and the forestland of the members covers 2,567 ha equivalent to 57% of the total private forest in the area. During the period the total area of the planting and tending is 4,185 ha, this means that a member executed 3.1 ha of forest operations per year in average, showing the high willingness on forest operations. In addition the joint works have resulted in the joint properties equivalent to 27 million Won and it will be an important foundation for operation of FMC which is a forest owners's cooperative organization for improvement of private forest management in this area. The total expenditure spent for the fostering of FMC amounted to 497,587 thousand Won and 58% of them were charged from KGFMP funds, 27% from the forest owners and 15% from public funds. The expenditure for investment was 273,104 thousand Won and 59% of the sum were appropriated as subsidies at the national level. The forest owners charged 43% of that and this means that each member invested approximately 100 thousand Won to his forestland per year in average. For the extension program 169,503 thousand Won were spent and it can be explained that 5,885 Won were spent per ha a year. The organization of FMC operated autonomously in a democratic way and the horizontal and leading extension system, which aspects the human rights, were very much effective in fostering the cooperative organization of forest owners for improvement of private forest management.

With the development of network and IT technology, people are searching and purchasing items they want, not bounded by places. Therefore, there are various studies on how to solve the scalability problem due to the rapidly increasing data in the recommendation system. In this paper, we propose an item-based collaborative filtering method using Tag weight and a recommendation technique using MapReduce method, which is a distributed parallel processing method. In order to improve speed and efficiency, the proposed method classifies items into categories in the preprocessing and groups according to the number of nodes. In each distributed node, data is processed by going through Map-Reduce step 4 times. In order to recommend better items to users, item tag weight is used in the similarity calculation. The experiment result indicated that the proposed method has been more enhanced the appropriacy compared to item-based method, and run efficiently on the large amounts of data.
