In the rapidly changing business environments, Internet companies have the characteristics of organizational culture that emphasize the flexible, open and autonomous nature of organizational culture, and are transforming into flexible smart working environment that is independent of time and place. Despite such an Internet business environment, the security management system still fails to reflect the business environment and organizational culture of the Internet company, and the control-focused security management system in the Internet company is facing limitations. Therefore, this study designed and developed Corporate members' autonomy-centered security items that considering the characteristics of the business environment and organizational culture of the Internet company. The results of this study are expected to be used to implement and operate corporate members' autonomy-centered security management system in internet companies with an agile business environment and an autonomous organizational culture.

The municipal solid waste (MSW) management system in one of the Class II Indian cities i.e. Rishikesh was studied and analysed to identify the key issues in solid waste management in the city. A total of 329 solid waste samples from 47 households were collected to characterize the household solid waste (HSW). The average (HSW) generation rate was 0.26 kg/c/d and it was composed of organic waste (57.3%), plastics (14%), paper (10.9%), and glass and ceramic (1.3%) and other materials (16.5%). There was an inverse relationship between household waste generation rate and family size (p < 0.05). The MSW management system practiced in Rishikesh is unsound. There is no waste segregation at source, no provisions of composting and no recycling by formal sector. The collection and transportation of waste is inadequate and inappropriate. Collected waste is dumped in open dumping site without scientific management. Following are some recommendations for developing a sustainable solid waste management system in Rishikesh city: (1) sensitize people for segregation at source; (2) promote reduction, reuse and recycling of wastes; (3) promote community based composting; (4) provision for 100% door to door collection and; (5) formalize the informal sectors such as rag pickers and recycling industries.

Korea and other countries have made various efforts to preserve soil. During the past several decades, Korea has implemented various policies on soil conservation practices; however, those policies have often lacked consideration of human and ecosystem risk management. while other countries have practiced various policies closely related to risk-based management for contaminated sites. Therefore, there is a great need for a paradigm shift of policy to better manage contaminated sites in risk-based strategies, while applying different management plans for soil and groundwater. In addition, the new policies should be administered with provision to improve soil health and related functions in ecosystem. This study has reviewed the trend in relevant policies in Korea and foreign countries to suggest the future policy directions for contaminated site management in Korea. For better management of contaminated sites, coherent policy that could complement the law, system, and relevant technology is required.

The whole objective of two papers in series was to develop the framework of an information management system (IMS) for soil-contaminated sites. In this work, we investigated current status of information management in our country and the IMSs of developed countries such as USA, Germany, Netherlands, and Japan. Through the investigation, we made four suggestions which could be taken into account for developing the IMS's framework. Firstly, we need to append the amendments on definition of information management and opening to the public to the Soil Environment Conservation Law. Secondly, detailed guidelines for each cleanup phase need to be developed. Thirdly, in order to increase the access of the public into the IMS, we need to provide electronic data files (e.g., PDF files) for them. Finally, a sole institution need to be chosen to control efficiently the IMS. In the subsequent paper, we will develop the framework of the IMS, based on the results of this work.

In this paper, we propose a novel behavioral model that explains the use of the military battlefield management system more effectively in the non-voluntary use environment. This study intends to suggest a model based on the Unified Theory of Acceptance and Use of Technology(UTAUT), an extended TAM. Also, it introduces the concept of 'Conative IS use' as a dependent variable that can explain user's behavior more effectively in non-voluntary technology acceptance environment. In addition, we propose the major factors affecting the UTAUT components from the TOE(Technology-Organization-Environment) perspectives, and analyze their effects. In order to validate the proposed model, this study applies PLS(Partial Least Squares) to the survey collected from military personnel. The findings of our study may shed a light on improving the effectiveness of battlefield management information system.

Due to the increasing use of smart phones, using Wifi, Wibro of mobile devices spread. Accordingly, Need of using peer-to-peer file sharing between mobile devices is growing. However, common Peer-to-Peer(P2P) system is too complex and is not suitable to be applied to mobile devices. Thus, the need of research has shown to improve way in a mobile environment that has a constraints as mobility and the scope of communication. Among them, there is a Chord as contents look up algorithm. Chord is the issue. Chord as the DHT-based P2P protocol shares files, index-key and distributed key across the network. However, exist Chord doesn't consider the mobility. So, It has a lot of problems in the mobile environment. Thus, in this paper, I will try to explore an appropriate way of Chord in a mobile environment.

Since the great acceleration, the emergence of the sustainable development concept amid the conflict between economic growth and the preservation of the natural environment is at a time when an efficient land-environmental plan integration system is needed to achieve a smart balance between development and conservation. Although preceding studies have been conducted domestically and internationally on various aspects, the operating system has not been implemented effectively. In this study, the policy concept of environmental policy integration, the current status of integrated management of land-environmental plans in South Korea, and related literature studies were reviewed to derive overall complementary points. In addition, the review was carried out by reorganizing the domestic urban planning legal-based system and the environmental legal-based system according to the same hierarchy to promote an effective integration system, and in foreign cases, the establishment of spatial and environmental plans in Germany and Japan was typically considered to derive implications for the establishment of an efficient interconnection system for the integrated management of domestic land-environmental plans in the future.
