With the increase of global competition and the reduction of the lifecycle of business process, most leading companies begin to adopt BPO(Business Process Outsourcing), by outsourcing the whole or part of their business process to external service providers and focusing on their core capability, in order to enhance their core competency, In adopting BPO, it is an important decision-making issue that which part of process should be outsourced. So identifying core/non-core process among the business processes is a prerequisite for managing corporate capability and performance of outsourcing. In this study, by focusing on knowledge intensity and degree of informatization of the business process that are important factors in adopting BPO, we have analyzed the current status of BPO adoption of domestic firms and proposed several guidelines for adopting BPO.

The problem of strategic R & D investment is formulate as a differential game model and solved explicity for a special case. It is shown that, at equilibrium, an increase in the intensity of market competition or a decrease in the role of technology transfer results in an increase in the initial rate of investment by competing tfirms. The increased initial investment rate may enhance the rate of technology development. This dynamic model can be used to propose non cooperative R & D investment policies in technologically competitive situation.

A survey was conducted on the inorganic and organic solute patterns of plants in connection with nitrate metabolism according to different light regimes (1.9, 16.0, 91.5 $Wm^{-2}$). Besides measuring in vivo NRA, we also quantitatively analyzed ater-soluble inorganic ions, organic acids, low molecular weight carbohydrates, amino aciss and total N (% DW). Among 4 Carex species, C. pilosa is known as shade-adapted species and the others as half (C. gracilis) to full (C. rostrata & C. distans) light-adapted species. Compared to species adapted to high light intensity, shade-adapted C. pilosa showed reduced productivity under the highest light intensity. In general, nitrate and amino acid levels decreased at higher light intensity, while sugar and organic acid concentrations increased. In C. pilosa osmolality tended to rise with increasing light intensity, while in the other species it tended to fall. Under low light intensity, the drop in soluble carbohydrate contents is osmotically compensated for by an enhanced nitrate concentration. It is concluded that competition between nitrate and $CO_2$reduction for reductants and ATP from photosynthesis may have important ecological consequences for the adaptation of plants to low or high light conditions. Additionally, the patterns of ionic changes due to increased light intensities were essentially the same in all selected species, indicating similar characteristics of heir mineral ion and organic acid metabolism as well as in field-grown Carex species.

Most Internet auction studies have focused on examining the determinants of auction success or closing price. However, there has been little previous research which investigates dark-side factors such as overbidding behavior in the Internet C2C transactions. For this reason, this study attempts to find situations with the escalation of commitment to bids using Internet auction systems and also examines whether the bidder's bidding is irrational. Therefore, this study applies escalation of commitment to explain the auction process such as the "going, going, gone period" with competition in Internet C2C auctions. In order to describe the auction process in terms of escalation of commitment, this study proposes psychological sunk costs, completion effect, and self-justification as the key factors of escalation of commitment and also willingness to continue bidding reflecting the decision maker's escalation behavior in terms of persistence perspective as final dependent variable. The results of PLS analysis indicate that a bidder's overbidding behavior is explained by the escalation of commitment.

Corruption is a serious political factor that distorts economic structure and slows economic development. In particular, the transition to the market opening economy increases the corruption incentives due to the transitional situation. The purpose of this study is to investigate the influencing factors on corruption using 2013 Myanmar Enterprise Survey data provided by World Bank. As a result of the analysis, it was found that the manager's willingness to dealing the regulation and the necessity of licensing had a positive relationship with corruption at the level of 90% and 95%, respectively. In the competitive environment factor, the intensity of the competition showed a significant increase at the level of 90%. In the institutional environment, the perception of social corruption and the obstacle of the taxation authorities increased the corruption. On the other hand, the increase in the instability of the political environment and strict enforcement of laws has been shown to reduce corruption. However, there was no significant relationship between managerial capacity, corruption of competitors, tax rate, and administrative environment.
