Noise pollution on the residential areas adjacent to urban expressway is a very severe situation. There has been a significant increases in the number of residential areas near urban expressway, and the quality of life in such areas is being degraded due to increased traffic volume and speed. In this study, several factors such as traffic volume, speed, and distance from noise source, etc. that affect the noise level were investigated for the residential areas near urban expressway. A correlation and regression model was built to examine the relationship between such traffic factors and noise. The study result found that traffic volume had a closer relationship with noise than speed had. Therefore, to decrease road traffic noise, it is more imperative to control traffic volume than traffic speed.

Purpose - In the context of economic globalization and the continuous development of international trade, as countries around the sea peninsula, port construction is particularly important. Based on the research on the influencing factors of port logistics development based on the allocation analysis, QCA (Qualitative Comparative Analysis) provides the basis for the planning and policy of port logistics development and has important theoretical value and practical significance for improving the level of port logistics management, reducing logistics operating costs and increasing economic benefits. In the tide of global integration for the development of port logistics, promote the growth of foreign trade economy of the city. It is also of great significance to the development and progress of commerce and trade. Design/methodology - Based on the relevant data samples of various ports in South Korea, this paper uses fsQCA (fuzzy set Qualitative Comparative Analysis) to integrate and analyze the influence mechanism of port logistics development and extracts five influencing factors of port logistics development, including the port's scale and infrastructure in the hard environment, port-neighboring enterprises in the soft environment, hinterland economy and government support. Findings - The five factors are unable to separately constitute the necessary and sufficient conditions of port logistics development, only a combined model can influence lake port logistics development. The scale and infrastructure of the port itself and port-neighboring ring enterprises are the main core conditions, which work together on the port, affect the throughput capacity of the port, and promote the development of port logistics. When the port-neighboring enterprises are not complete and the scale is low, the growth of port throughput will be restrained and the development of port logistics will be affected, whether the hinterland economic benefits are general, the development of port-neighboring enterprises is insufficient, or the government supports are limited. Originality/value - Through the research on the development of port logistics in South Korea from the perspective of configuration, this paper finds the configuration influence of hard environment and soft environment on the development of port logistics, which has important theoretical and practical significance for better promoting the development of port logistics in South Korea.

The managing strategies of each enterprise has been fundamentally changed due to the emergence of digital economics by using the internet. Therefore it is indispensable for each enterprise to be changed their business strategies. With a view to meeting the change of new economic paradigm, they are efforting to build a infrastructure for information and communication, induce foreign capital, reconsider their conditions of location, draw the law concerned and reinforce education for experts etc. In consideration of these change, the KwangYang port have to introduce e-Business for the purpose of increasing the level of their competition. We - our government, the companies - concerned with port management should recognize and use efficiently our core competence and potentiality of our port management. To achieve it, firstly port industries are to handle not only international logistic system but also communication, finance and sightseeing. Secondly, the developed off-line system have to be harmonizing with the on-line. Therefore, this paper are focused to suggest the theoretic background by analyzing the strategic points of e-port which are divided in 6C - Contents, Community, Connection, Commerce, Communication and Customization.

This paper aims to present a prospective trend to establish a proper CALS conception and an efficient CALS environment in Korea.. It is crucial at this point for Korea to develop a comprehensive CALS conception which considers our present economic and social situation, national security, and our national emotion. Korean CALS has been developed and led mainly by the government and private industry. It is now necessary to improve CALS conception in Korea by making CALS standard more interchangeable among international as well as domestic business fields through EDI and the automation of the industries along with the government. In this regard, this paper proposes three potential methods to accomplish this goal and discuss each of them in detail. First, we suggest to establish a proper CALS introduction policy on the government level. We propose an introduction policy with three phases such as introduction, spreading and target which will cover through the year 1996 to 2007. Second. we suggest to establish a proper CALS standardization policy by improving the acquisition of digital data and process, and modernizing infrastructure. Third, we suggest that the government should amend and enforce the necessary laws and acts for more efficient CALS implementation in Korea. Government should arrange for these acts to be applied not optionally but obligatorily to Korean enterprises so that they survive the harsh and competitive world market in the upcoming 21th century.

With a view to meeting the change of new economic paradigm, they are efforting to build a infrastructure for information and communication, induce foreign capital, reconsider their conditions of location, draw the law concerned and reinforce education for experts etc. In consideration of these change, the Pusan port & the KwangYang port have to introduce e-Business for the purpose of increasing the level of their competition. We - our government, the companies - concerned with port management should recognize and use efficiently our core competence and potentiality of our port management. To achieve it, firstly port industries are to handle not only international logistic system but also communication, finance and sightseeing.

A need for sharing the R&D information at a national level regardless of the ministry in charge of it is being aroused. However, this information is being managed by different institutes under different ministries without a standard identifier which makes it difficult to manage the information such as to look up duplicate projects. A URN-based identifier is required for the integrated management and utilization of the national R&D information. In this paper, the concept of the identification metadata for applying the identification system and the status of the information management by each institute will be the subject for discussion. Based on this, the elements required for issuing a unique identification number and identifier to the national R&D projects will be suggested in this paper.

Sub-station, key equipment in electric power infrastructure, are being exposed to increasing risk of hacking. For this, soft redundancy sub-station system needs to be formulated with automatic restoration mechanism. For this it is important to assess the reliability of the applicable range of data that are used in actual system operation, as well as the methods and findings of the tests. At the same time performance of soft redundancy system and total security mechanism, which are aligned for the protection of the sub-station, need to be tested. For testing the above-mentioned, this paper presented a viable formation of a soft redundancy practical VPN system within a panel to protect the latter from hacking or cracking incidences, and conducts a test to check if the considered system actually serves the protection function in the actual operation setting, gathering evidence from the data from the testing of the actual performance of the system as well as of emergency scenario simulation operations. Because tested soft-redundancy & restorative sub-station system is expected to be widely applicable for various cases such as Smart-grid or electricity IT system, where VPN with enhanced level of security is required.

Composting is an ecologically sound method of recycling organic waste. Its advantages include the maintenance of soil fertility and improvement of soil physicochemical property. It is an essential part of the waste minimization. That is, composting should be included to increase the recycling rate up to more than 20%. To encourage composting of waste, it is necessary to develop some effective composters of small scale facilities and densely populated areas. For medium and large-size facilities, the optimum process should be selected. Technical counselling and support is desirable for small scale composters for urban residential and rural area. On the other hand, adequate amendment of relevant legislation should be followed to encourage composting. An example of unreasonable legislation is the current fertilizer management act. According to the regulation, the maximum allowable limit of lead in the compost is less than 150ppm, which is too strict. This limit should be increased to at least 300ppm, which is the observed level in most states in USA. At the same time, sound infrastructure should be established and decent publicity work should be achieved to accelerate composting activity. In this paper the desirable standard for some heavy metal concentration in the compost were suggested.
