This study intends to find the empirical relationship between the environmental and organizational characteristics and the strategic use of information systems(SUIS). Sixty-five firms in Korea are surveyed and analyzed to understand the impact of these characteristics on SUIS. As environmental characteristics, we select dynamism, hostility, and heterogeneity. As organizational characteristics, we select centralization, formalization, and IS maturity. The result of correlation analysis shows that formalization and information systems maturity are correlated significantly with SUIS. The result of regression analysis reveals that formalization is a major determinant to influence on SUIS of organization. Also, additional analysis shows that service industry have higher extent of SUIS than manufacturing industry.

Purpose In this study, the relationships among environmental information exchange with suppliers(EIES), green collaboration with suppliers, green learning by environmental information, the adoption of green supply-chain management techniques(AGSMT) (i.e., the green purchasing, product design and production, and the recovery of extra facilities and inventories), environmental performance, and the organizational performance of a firm were empirically investigated. Design/methodology/approach Data for this study were drawn from a survey of the current status of EIES levels and AGSMT usage observed in Korean manufacturing firms. In total, 500 organizations were randomly selected from a population of about 1,000 firms that are listed on the Korean stock market. In order to collect empirical data, this research administered questionnaires with the sample firms. Only chief production executives were selected as respondents. A questionnaire with a cover letter was mailed to each respondent. The survey was conducted during a 3-month period between March 2015 and June 2015. Finally, 78 valid data of the sample firms were collected. Findings The results of this study showed that EIES positively affects the green corporation and learning. According to the results, it was observed that both green corporation and green learning have a positive impact on the levels of AGSMT(i.e., the green purchasing, product design and production). It was also demonstrated that AGSMT has a direct positive impact on environmental performance. In examining the effects of environmental performance on the organizational performance of a firm, significant impact was found.

This paper investigates the moderating effect of firm size on the relationship between environmental uncertainty and logistics information systems fit and performance, and suggests logistics strategies that would help to achieve goals. Based on our empirical research results, the findings of this paper can be summarized as follows: First, firms with higher levels of harmony between environmental uncertainty and logistics information systems fit featured significantly better logistics performance than firms with lower levels of fit. Second, logistical performance can be maximized based on the firm size and the harmonization between environmental uncertainty and logistics information systems. The results of this study will assist firms align and focus on improving competitive strategies for logistics systems.

Environmental monitoring systems using Wireless Sensor Networks (WSNs) face the challenge of high power consumption, due to the high levels of multi-hop data communication involved. In order to overcome the issue of fast energy depletion, a proof-of-concept implementation proves that adopting a clustering algorithm in environmental monitoring applications will significantly reduce the total power consumption for environment sensor nodes. In this paper, an energy-efficient WSN-based environmental monitoring system is proposed and implemented, using eight sensor nodes deployed over an area of $1km^2$, which took place in the city of Tabuk in Saudi Arabia. The effectiveness of the proposed environmental monitoring system has been demonstrated through adopting a number of real experimental studies.

Modern society, as a result of high industrial technology, is characterized by a series of mass production, moss consumption and mass disposal. As the mass disposal is known as the major culprit of destroying ecological system of our environment, human prosperity is in turn threatened by this indiscrete activities. Under current industrial technology which pursuit maximum profit, environmental problems could not be solved. This paper proposes recycle manufacturing systems of assemble products as a measure of current non-recycle manufacturing systems. Products are also composed of a number of ports. All parts are represented by a function of time cost performance variable as reuse level. We develop on information systems which give all the information on reused and recycled parts. We try to implement this result on a real fields. We confide ourselves to the contribution to on effective solution of environmental problems and to give profit to assembly manufacturing and consumers.

This article shows a set of physical information fusion IoT systems that we designed for smart buildings. Its essence is a computer system that combines physical quantities in buildings with quantitative analysis and control. In the part of the Internet of Things, its mechanism is controlled by a monitoring system based on sensor networks and computer-based algorithms. Based on the design idea of the agent, we have realized human-machine interaction (HMI) and machine-machine interaction (MMI). Among them, HMI is realized through human-machine interaction, while MMI is realized through embedded computing, sensors, controllers, and execution. Device and wireless communication network. This article mainly focuses on the function of wireless sensor networks and MMI in environmental monitoring. This function plays a fundamental role in building security, environmental control, HVAC, and other smart building control systems. The article not only discusses various network applications and their implementation based on agent design but also demonstrates our collaborative information fusion strategy. This strategy can provide a stable incentive method for the system through collaborative information fusion when the sensor system is unstable in the physical measurements, thereby preventing system jitter and unstable response caused by uncertain disturbances and environmental factors. This article also gives the results of the system test. The results show that through the CPS interaction of HMI and MMI, the intelligent building IoT system can achieve comprehensive monitoring, thereby providing support and expansion for advanced automation management.

Increasing concern for the environment in Korea has led to the demand that major policies and large-scale development projects be subjected to detailed impact assessment. This paper reports on the state of data related to the prediction of the environmental impact (EIA) to emphasize the importance of data quality. Environmental impact statements (EIS) consulted with the Ministry of Environment of Korea were analyzed from 1981 through 1992. Many of assessors used existing data and collected supplementary data from field survey. Most of the results of EIA are presented directly or summarized on maps and as graphics. For the national purpose, large source of quality-controlled data such as atmospheric data have been developed, However, there are the deficiency in data to analyze the impact of human activity, and data gaps and incompatibilities among systems. Consequently, the development of data bank systems including computer database and remotely-sensed satellite data is required to improve the quality of data which are relevant to EIA. The data bank system should be organized meaningfully in minimum time with a least cost, and measurement standards must be made explicit. Geographical information systems (GIS) are applicable to the graphic presentation or to the impact prediction model.

The EU has introduced various environmental protection policies and regulations which are stricter than accepted international standards. WEEE, RoHS, and EuP directives in the Electrical and Electronic Industry could have a direct effect on our exports to EU countries. To gradually enlarge exports to the EU, it is necessary to have a precise understanding of the EU's environmental regulations and prepare the relevant countermeasures to adequately cope with them. Korean companies should formulate concrete plans to meet the EU's environmental regulations in those industry. In order to decrease the negative effects that environmental regulations of EU give to Korea, the corporations and the government should change their present passive environmental policy and carry out the environmental- friendly policy. If Korean companies can adequately meet the standards set by the environmental policies and regulations of the EU, it will greatly enhance the competitiveness of companies in this market.
