In this study, the bathymetric data acquired from 2018 to 2020 and the precipitation and suspended sediment data were analyzed for changes in bathymetry owing to the discharge from the Nakdong River barrier and environmental factors, especially the torrential rain in 2020. Sediment erosion and deposition processes are repeated because of complex environmental factors such as discharge from the Nakdong River barrier and the influence of waves generated from the external sea. In the first half of the year after the dry season, bathymetric data showed relative erosion trends, whereas in the second half after the flood season, deposition trends were identified owing to the increase in sediment transport. However, the data from the second half of 2020 showed a large amount of erosion, resulting in tendencies different to those of erosion in the first half and deposition in the second half of the year. This result is judged to be influenced by the weather in the summer of 2020. The torrential rain in the summer of 2020 resulted in a higher force of erosion than that of deposition. In summary, the tendency for erosion is more significant than that of sedimentation, especially in the main channel area of the Nakdong River.

Environmental pollution and climate change in Vietnam are now becoming a major concern. This situation is increasing the pressure on the companies to improve their social responsibility in production and business activities and disclose the environmental information to meet the requirements of stakeholders. This study investigates the internal and external factors of the company that affects the environmental information disclosure of listed companies on the Vietnam stock market as business sector, firm size, corporate manager perceptions, profitability, financial leverage, community pressure, pressures from stakeholders, government pressure influencing environmental information disclosure. Analytical data collected through the survey of 120 listed companies on the Ho Chi Minh City Stock Exchange (HOSE). By testing Cronbach's Alpha, exploratory factor analysis (EFA) and logistic regression analysis, the results of the study show that the level of environmental information disclosure of listed companies on the stock market in Vietnam depends heavily on government regulations, followed by the pressure from stakeholders, community pressure, views of business managers, companies size, business sector, and particularly profitability and financial leverage factors that have a negative relationship with environmental information disclosure.

Comtemporary firms need capability of acquiring external knowledge and internalizing it to cope with environmental fluctuation. The paper analyzes the impact of absorptive capacity, an ability to recognize and utilize external knowledge, on knowledge acquisition of the firm, and examines the role of trust in the knowledge acquisition process. Data were collected from 84 domestic companies that had adopted ERP packages. The results indicate that prior experiences of knowledge acquisition, communication mechanism, and conflict resolution mechanism affect knowledge acquisition positively. Among those independent variables, communication mechanism and conflict resolution mechanism significantly and positively related with trust. Trust is, in turn, positively associated with knowledge acquisition. Meanwhile, previous knowledge base and prior relationship with the knowledge provider do not affect knowledge acquisition. Further, the results provide evidence that trust plays a mediating role between other absorptive capacity factors and knowledge acquisition.

Performance of public hospitals is difficult to define and measure because not only their managerial or financial performance but also their role as a public entity is important. The purpose of this paper is to examine the internal and external factors that influence the performance of local government hospitals. A multiple regression was performed to analyze the effects of the environmental, organizational, operational, and cost-related factors on the return on total assets(ROA), operating margin(OM), and the ratio of Medicaid patients. Empirical results show that financial performance (ROA and OM) are more influenced by operational or cost-related factors, while the ratio of Medicaid patients is more affected by environmental or organizational characteristics. It is noteworthy that competition and the contract with private sector management have negative effects on the ratio of Medicaid patients that local government hospitals treat.

The purpose of this study is to clarify the expansion of functions of clothes by analyzing the characteristics of transformation, and to forecast future trends in fashion through systematization of the aforementioned analyses. Analysis of 20th century Modernism and Post-Modernism in a sociocultural sense confirms that transformation in clothes was formed by environmental, functional, deconstructive, and expressive factors. In this sense, the formative factors mentioned above conceptually include nomadic characteristics, usefulness, irregularity, and expressiveness. The nomadic characteristics found in clothes transformation signify the change of clothes into environmental nomadic everyday implements, used as tools for the body. Usefulness of clothes means that it is worn for variability, multipurpose multi-functionality, and combined multiple use. Irregularity means the clothes can change indefinitely, according to random manipulation on the wearer's part. Last of all, expressiveness conveys the designer's internal sensitivity and imagination onto an external object through the induction of various expressive factors.

In recent years, the demand for green buildings is growing fast due to legislative and social pressures. Construction organizations, which play an important role in promoting building industry growth, are facing with challenges on how to adapt themselves to enhance sustainability of the buildings. In this paper, the green value chain and system frameworks, an extend application of Porter's value chain and system models, are introduced. Based on deep analysis of the green value chain and system frameworks, a revolution model for construction organizations towards green building is created. Management factors critical for a successful green building project, at the firm and project organization level, are extracted. Furthermore, external critical relationships are also identified. Fully understanding of these management factors and the model can help and enable practitioner to know what new capabilities should be deployed and developed in the long run for maximizing sustainability.

The study is based on the technology-organization-environment (TOE) model which, attempted to determine the factors that are going to influence ICT adoption. The proposed research model evaluates the interplay among technological context (IT infrastructure, system security, and user capacity), organizational context (top management commitment, and innovations strategies), environmental context (quick response to the external agencies, interactive network infrastructure, and competitive pressure) and ICT adoption (productivity growth, organizational change, and competitiveness). Data were collected from 243 senior executives of full member firms of the Bangladesh Garments and Manufacturers Association (BGMEA) of examining the relationships among the constructs in the proposed framework utilizing structural equation modeling (SEM). The analysis of TOE factors revealed that environmental, organizational, and technological factors have a significant impact on the successful implementation of ICT tools. The study also discusses implications for management practitioners.

As the demands of ocean resource development increase, many offshore structures are required. To cope with the active ocean developments, many types of construction methods have been applied for offshore facilities, including oil, gas and harbors. One of the challenges is to transport and install the heave bridge caisson. Several construction methods are well understood. However, for the sake of safety and reliability, the F/D installation method can be utilized. While the caisson is carried by an F/D, the mooring force of the tug boat and the structure stability from exiting motions in the dock should be checked against external loadings and sea conditions. The external loads can be classified with wind force, current force, and wave force. In the stability analysis, transportation velocity and draft of F/D are important factors. The dynamic stability and hook load for crane barge installation for the same caisson are also studied. Considering external loads and dominant factors, the stability of caisson during transportation has been investigated.
