The company can maximize the shareholders＇ equities, the prosperity of the owners of interests, the reputation of the company, and the long-term viability of the company by undertaking the CSR. The controversy whether the company should be engaged in CSR or not is still going on. According to the shareholder theory, the supporters of CSR （Donaldson ＆ Preston, 1995; Jones, 1995） say that CSR is a mechanism to achieve a better financial condition and to maximize the property of the shareholders （A. Mackey, T. B. Mackey, ＆ Barney, 2007）. This research investigates in three folds, the relationships among corporate governance, CSR, and firm performance, then the relationship between intellectual property and firm performance. This research shows that the independent board of commissioners is related to CSR. CSR and the institutional ownership are also related to firm performance. In addition, intellectual property is strongly related to firm performance. This means that intellectual property owned by public-limited companies in Indonesia increases firm performance.展开更多

Then the enumeration problem of IP consists of counting the numbers of different classes and counting the cardinality of each class that is highly related to the scale of key space for a multivariate publi9 key cryptosystem. In this paper we show the enumeration of the equivalence classes containing ∑n-1 i=0 aiX^2qi when char（Fq） = 2, which implies that these polynomials are all weak IP instances. Moreover, we study the cardinality of an equivalence class containing the binomial aX2qi ＋ bX2qj （i ≠ j） over Fqn without the restriction that char（Fq） = 2, which gives us a deeper understanding of finite geometry as a tool to investigate the enumeration problem of IP.展开更多
