A great number of companies are currently examining the opportunities made available through the internet. This research aims to identify the factors that influence the adoption of the internet market. The innovation-IT-diffusion theory provide the theoretical foundation for this study. Seven factors were found to influence the adoption level of the internet market. They are top management support, cost efficiency, inclination toward new technology, absorptive capacity, institutional support, competitors move and customer pressure. Nonparametric test was used to test hypotheses. The results shows that top management support is the most important factor, and institutional support is not related to the adoption of the internet market.

Purpose - Diversity subject is rising globally, as the proportion of women in the workforce increased to a large extent and the variety of resources became greater. Diversity attempts have appealed more awareness to the value of female participation in various areas, notably in the boardroom and corporate governance. This study tests the relationships among gender diversity, openness, and innovation, at the firm level across countries from the MOI Survey. Research design, data, and methodology - In this study the relationships among gender diversity, openness, and innovation were investigated at the firm level across countries from the Management, Organisation, and Innovation (MOI) Survey. A cross-cultural analysis was conducted based on the empirical evidence from six countries: Germany, India, Lithuania, Poland, Romania, and Russia. Result - The results show that gender diversity is positively related to innovation performance, moreover openness is positively associated with the level of firm innovation. In addition, a company's capability to use knowledge from outside and the creation of new combinations positively influence a firm's potential to innovate.

In the quiescent state, cattle-manure slurry stratifies into three discernible layers, namely a floating scum layer, a bottom sludge layer and a watery middle layer. The proportions of top (scum), middle and bottom (sludge) layers were approximately 20, 60 and 20% respectively of the volume of the whole slurry. Particulate matter from the different stratified layers was characterised for particle size distribution and cellulose, hemicellulose and lignin composition. Total solids concentrations of top, middle and bottom layers were 12.7, 2.8 and 7.4% respectively. Larger particles were found in the top layer compared with the bottom. The top layer contained the highest amounts of Neutral Detergent Fibre (NDF), Acid Detergent Fibre (ADF), cellulose and hemicellulose, but the lowest amount of Total Kjeldahl Nitrogen (TKN). The bottom layer contained the highest amounts of Acid Detergent Lignin (ADL) and TKN. With increase in particle size, there were increases in NDF, ADF, cellulose and hemicellulose, accompanied by decreases in ADL and TKN. Biochemical methane potential of the three layers was also measured. The top layer was found to produce the most methane with the middle layer producing the least. Biomethanation rate from the top layer was also the highest. Differences in biomethanation rates and biochemical methane potential were attributed to differences in chemical composition of the particulate matter. About 48%, 23% and 30% of the total chemical oxygen demand (COD) in the top, middle and bottom layers respectively of the slurry was found to be degradable.

The caving property of top coal is a key factor to the success of top coal caving mining. The influence law of cyclic loading and unloading of hydraulic support on top coal caving is of great significance to improve the recovery rate of top coal. The similar simulation methods were used to study the dynamic evolution of the top coal cracks under the multi-cycle action of the support, and the parameters of top coal cracks were analyzed quantitatively in this paper. The results show that the top coal cracks can be divided into horizontal cracks and vertical cracks under the cyclic loading and unloading of the support. With the increase of the times of the support cycles loading and unloading, the load on the support decreases, the fractal dimension of the cracks increases, the number and total length of the top coal cracks increases, and the top coal caving is getting better. With the increase of the times of multi-cycle loading and unloading, the fractal dimension, total crack length and crack rate of top coal show a trend of rapid increase first and then increase slowly. Both the total length of the top coal cracks and the crack rate basically show linear growth with the change of the fractal dimension. The top coal caving can be well improved and the coal resource recovery rate increased through the multi-cycle loading and unloading.

This paper examines relation between growth of adult top shell and their selectivity over different marine algae. For the study the top shell density and the algal species in different depth were surveyed by SCUBA. To test selectivity over different types of algae, five algal species including Ecklonia cava, Undaria pinnatifida, Ulva spp, Gelidium amansii and Sargassum spp were provided to top shells in indoor water tank condition. In the field survey, the wet weight of Ecklonia cava was significantly (r = 0.612, p < 0.05) correlated to the shell length (SL) of top shell. In the indoor water tank experiment conducted over 12 hours after sunrise, adult top shell (SL > SL 4.5 cm) tended to select Ecklonia cava and Undaria pinnatifida, which are common and abundant algal in the subtidal waters in Jeju Island. Our field survey and the indoor experiment suggest that E. cava and U. pinnatifida could be food preferred by adult top shell in its habitat.

The purpose of this study is to assess and develop effective MIS planning method by applying the CSF method. With the comparative analysis of the Rockart's basic concept of CSF and the examples of the corporations which employed CSF methodology, a new CSF method more suitable to Korean business environment is proposed and applied to another company for evaluation. The new CSF methodology consists of three steps. The first step is to preexamine the business conditions. The second step contains an Introductory Workshop, interview with the managers, survey questionnaire, Focusing Workshop, and decision of the priorities for system development. The third step is a real development of an information system out of the first and second steps. As a result of this study, it is found that revised CSF method can induce top management to participate more in the activities of information system development and that it can make top management to focus on the critical area. The fulfillment of the information requirement out of the enhanced MIS planning will lead to more successful management activities.

This paper presents a study on construction safety in the People Democratic Republic of Laos (PDRL). Fifty workers experienced certain injuries in their construction sites and 15 top managers were interviewed in twenty-six construction projects in Vientiane, the capital of PDRL. Research results show that stepping on and/or striking against objects (48%), struck by falling objects (24%), falling of persons (12%) are major types of construction injuries. The paper stresses that the ignorance of top managers about their crucial role in safety improvement, using safety incentive to raise safety performance, lack of thorough understanding about benefit from labor safety performance, and the willingness to cut off safety performance expenditures is considered as obstructions of safety improvement programs. The survey indicates that physical working conditions, relationship among workers, foremen behaviors and the monthly wage were influencing factors to worker's job satisfaction. The study also highlights afternoon as dominant time that led to a large number of injuries.
