The successful management of software (SW) projects is a continuous concern to managers, which is attributed to the contradictory demands that most projects are facing; meeting user requirements within time and budget limit while flexibly dealing risks during the progress of the projects. The present study asserts project performance and risk mitigation are not tradeoff but to be achieved simultaneously, which is called SW project ambidexterity. Drawing on the literature on organizational behavior, hypotheses are developed speculating the relation among project performance, risk mitigation, team collective improvisation, team behavioral integration, and team diversity. Using empirical data collected from 102 SW project teams of 507 team members in South Korea, empirical analysis indicates team collective improvisation is a significant antecedent to SW project ambidexterity, playing a pivotal role to balance the contradictory demands. Furthermore, team behavioral integration positively influences the degree of team collective improvisation, and the magnitude of the relation is partially contingent on the team members' age and major diversity. The present study advances theory by providing a context specific explanation about the SW project ambidexterity and its precedents.

As one of the key parameters to determine $CO_2$ flux between air - sea interface, it is quite important to know p$CO_2$, which has involved much uncertainty, mainly due to the complex variations of sea surface p$CO_2$ and the paucity of samples, made in ocean. In order to improve the interrelationship between partial pressure (p$CO_2$) and different physical and biochemical parameters in global sea surface water, a new empirical relation is established to correlate and parameterize p$CO_2$ in the mixed layer using the data from recent WOCE cruises. Meanwhile, by new empirical relation, abundant historical hydrographic and nutrients ship data, Levitus data set and NOAA/AVHRR(SST), p$CO_2$ have been accumulated and applied. Then effort has to be made fur promotion of this study to correlate and parameterize p$CO_2$ in the mixed Layer with different physical and biochemical parameters. and further attribute this huge historical data sets and NOAA/AVHRR(SST) data to estimate p$CO_2$. In this paper we analyzed more interrelationship between the model and ship/satellite data set. Finally, the inter-annual variations of p$CO_2$ in sea are presented and discussed.

The purpose of this study is to investigate empirically interaction among the financing decision, investment decision, and profitability by using 41 fisheries corporations in Korea, and to suggest implications of the empirical results for government's financial policy for fisheries corporations. Sample period is 19 years from 1982 till 2000. This analysis method employs the two stage least squares(2SLS) estimation method. From the results of regression analysis by 2SLS estimation method, the adjusted $R^2$ values were high and the overall F values indicated significant. The empirical results of this study are as follows; (1) determinant factors of capital structure model for fisheries are profitability, firm-size, fisheries investment of total asset, and business risk. As pecking order theory explains, the higher is profitability the lower is debt ratio. The larger firm-size, the higher is debt ratio. The higher is fisheries investment of total asset and business risk, the higher is debt ratio. (2) determinant factors of investment model for fisheries are the change of sales, business risk, and debt ratio. These factors have positive relation to fisheries investment of total asset (3) determinant factors of profitability model for fisheries are fisheries investment of total asset and debt ratio. These factors have negative relation to profitability. On the basis of analysis results, on the government's financial policy for fisheries corporations, I suggests that with interest rate reduction, the government should lend more funds to solve the crisis in the financial structure of the fisheries firms

A useful radiance-converting method was developed to convert the Landsat-7 ETM+thermal-infrared (TIR) band's radiance ($L_{{\lambda},L7/ETM+}$) to that of Landsat-5 TM TIR ($L_{{\lambda},L5/TM+})$ as: $L_{{\lambda},L5/TM}=0.9699{\times}L_{{\lambda},L7/ETM+}+0.1074\;(R^2=1)$. In addition, based on the radiance-converting equation and the linear relation between digital number (DN) and at-satellite radiance, a DN-converting equation can be established to convert DN value of the TIR band between Landsat-5 and Landsat-7. Via this method, it is easy to integrate Landsat-5 and Landsat-7 TIR data to retrieve the sea surface temperature (SST) in coastal waters on the basis of local empirical algorithms in which the radiance or DN of Lansat-5 and 7 TIR band is usually the only input independent variable. The method was employed in a local empirical algorithm in Daya Bay, China, to detect the thermal pollution of cooling water discharge from the Daya Bay nuclear power station (DNPS). This work demonstrates that radiance conversion is an effective approach to integration of Landsat-5 and Landsat-7 data in the process of a SST retrieval which is based on local empirical algorithms.

The purpose of this empirical study is to investigate the impact of the performance of ITBI's tenant. The study also aims to find out the relation between tenant's output and variables such as service usage, service quality, customer satisfaction. To achieve this aim, we carried out both a review of the literature and an empirical research. To verify the relation of each variable, structural equation model analysis using AMOS4.0 is performed. The results are as follows. First, service usage of ITBI's have significant positive effects on customer satisfaction of business incubation center. On the other hand, service quality of ITBI's doesn't have direct effects on customer satisfaction of business incubation center. Second, customer satisfaction of business incubation center have significant positive effects on technology development. Third, managerial improvement of tenant have significant positive effects on the total sales. On the other hand, technology development doesn't have direct effects on the total sales. According to those results, the business incubation center should improve the service quality and customer satisfaction. Also, the center make every effort to connect the perforated line in structural equation model. The implications of these findings and possibilities of further research are discussed.

The rapid changing technology and globalization allow consumers get information and new products or services faster, have more choices than before, which might be causing more competitive and more uncertain demand. The relationship quality between enterprises positively influence the relational performance. Through this research, enterprises should realize the importance of relationship learning to improve the competitive advantage. Also this research provide the strategic solutions to promote the relationship learning. this is considered to be able to present an improved directionality of the relationship between the buyer and the supplier. In addition, from the perspective of policy, this research provides implications for large enterprises and SMEs to promote their coexistence relation. The empirical model of this paper is established on basis of previous research. The empirical results show that: first, as the influence factors, relation solidarity level, environmental uncertainty, learning intension affect relationship learning, whilst special transaction assets influence information shared and relationship memory and have no effect on mutual understanding; second, relationship learning influence on relational performance and this influence relation becomes stronger if the relationship trust is higher.

Many companies are adopting performance measurement systems(PMS) in order to acquire competitive advantage the promote long-term growth in Coping with the rapidly changing business environment. Prior research has focused on the relation between PMS and organizational performance. However, there is limited empirical research that examines the behavioural consequences of PMS. Further, there is little empirical research that examines whether measurement diversity have direct and/or indirect effects on work performance. As such, I examine how the relation between measurement diversity and managerial performance can be explained by the intervening variables of justice and organizational citizenship behaviour. This study is summarized as follows: this study finds that measurement diversity affect managerial performance indirectly through justice and organizational citizenship behaviour.

Using an international setting, this study investigates the relation between cash holdings and financial reporting quality, measured by accruals quality. Empirical results show that the balance of cash holdings is positively related to the opacity of financial reporting in non-U.S. international markets. The relation becomes stronger as the strength of investor protection increases, implying that precautionary motives, instead of agency motives, drive the increase of cash holdings of opaque firms. In addition, the positive relation is stronger for discretionary accruals quality. The decomposition of the aspects of investor protection shows that public enforcement through regulation authorities is the main driver of the positive relation between cash holdings and the opacity of financial reporting.
