Cities should be developed and managed deliberately since reckless development and selfish expansion deteriorate the quality of life in the cities by creating various problems in transportation, residence and environment. In particular, the semi-agricultural zones have been designated in order to address such problems as the overpopulation caused by the influx of people into the cities and promote balanced regional development and eco-friendly cultivation of the land across the nation. But the problems of metropolitan areas, such as the overpopulation and lack of infrastructure, are spreading even to the semi-agricultural zones, which should be the last areas to be developed into cities. We should blame the indolence of our policies on land first, rather than the selfish cities that slip from the grip of the law. This study concludes that the self-agricultural zones should be developed and managed with plans by the public sector rather than the autonomous development by the private sector.

Recently, there are environmental issues for sustainable transportation system to pursue the energy-efficient and environment-friendly public urban transit. These transportation system needs to offer demand-oriented high-quality service being on the same level with cab service for urban space. PRT(Personal Rapid Transit), small track-guided vehicle, is repeatedly mentioned as a possible alternative for the new urban public transportion system, but but there are not many researches on the operational optimal routing for PRT network. In this paper, the concept of PRT and general optimal routing methods are reviewed. And we suggest the optimal routing method for city-wide PRT network with multi-vehicles and stations, junctions and directional arcs. Futher research directions for PRT routing are presented.

The uniformity of lighting distribution on the roadway is essential factor for drivers and pedestrians's safety during nighttime in urban streets. Also, the importance of roadside trees is one of the growing concern for better citizens' health and mitigating environmental impact on the urban street. But roadway lightings and roadside trees have different design or planting standards and they are not integrated in the systemic viewpoint for better safety of users during nighttime. The purpose of this study is to propose a simulation approach which assesses lighting quality in the view of illumination uniformity distribution of roadway lighting from design step and consider the layout of roadside trees. For improving lighting quality of roadway, simulation approach is needed for assessing the impact of diverse planting situation of trees and encouraged from beginning of design step for roadway construction.

Many Korean companies are challenged to reduce logistics cost and meet environmental-friendly logistics. The textile companies in harsh competition are requested to make improvement on their logistics environment to cut down the total cost. However, they have reached the limit on improving the manufacturing process. We believe that the logistics department is the most improvable part at present. Improving logistics will be highly effective to cut down the total cost. In this study, we present Pad Pool System(PPS) as the solution to save their logistics cost. PPS, which means the shared use of Styrofoam pads, will enable the textile companies to cut down their cost and strengthen enterprise competitiveness. Also, PPS will be helpful reducing environmental disruption because the system reuses retrieved Styrofoam pads many times.

Until now, the eco-friendly construction (green construction) has been focused on reducing environmental impacts in use(operation and maintenance) phase. Considering the environmental influence along the life cycle of construction project, the impact in execution phase is rather lower than that in use phase. However, that impact is thought to be greatly decreased by well-organized activities. Based on its urgency and requirement for timely action, this study aimed to discuss the greenhouse gas (GHG) reduction plan in execution phase from a broad perspective. To achieve this purpose, the green building rating systems in domestic and foreign countries have been reviewed, and the practice in Japan was investigated. In order to improve current on-site greenhouse gas management, the integration among construction phases, participants, and environmental factors, and institutional supports are required as well as the contractor's efforts.

Since the mass mortality of Quercus mongolica has been first reported in Gyeonggi province at 2004, the disease spread rapidly over Korean peninsula annually. Ambrosia beetle (Platypus koryoensis) was known as the insect vector of oak wilt fungus, Raffaelea quercus-mongolicae, and control methods of the disease had mainly been focused on eradication of insect vector. However, for the efficient management of the disease, combined control methods for both of the pathogenic fungus and insect vector are strongly required. As one of the efforts to suppress the pathogenic fungus, antifungal activities of Streptomyces isolated from oak forest soil were assayed in this study. Optimum culture condition for the selected isolates was also studied, As a result, Streptomyces blastmyceticus cultured in PDB (Potato Dextrose Broth) at $25^{\circ}C$ for 1 week showed the strongest antifungal activity against oak wilt fungus. Mycelial growth inhibition rates (MGIRs) of Streptomyces isolates were compared on culture media supplemented with heated and unheated culture filtrates of S. blastmyceticus. MGIRs on culture media with unheated culture filtrates were generally higher than those on culture media with heated culture filtrates. Antagonistic mechanism to get involved in the inhibition of hyphal growth and spore formation of the pathogen is due to the antifungal metabolites produced by Streptomyces. This study will provide the fundamental information in developing biocontrol agents for the environment-friendly management of oak wilt disease.

Impervious areas have been expanded by urbanization and the natural structure of water circulation has been destroyed. The limits of centralized management for controlling storm water runoff in urban areas have been suggested. Low impact development (LID) technologies have been promoted as a crucial alternative, establishing a connection with city development plans to build green infrastructures in environmentally friendly cities. Thus, the improvement of water circulation and the control of nonpoint source were simulated through XP-SWMM (storm water and wastewater management model for experts) in this study. The application of multiple LID combination practices with permeable pavements, bioretention cells, and gutter filters were observed as reducing the highest runoff volume by up to 70%. The results from four different LID installation scenarios indicated that permeable paving is the most effective method for reducing storm water runoff. The rate of storm water runoff volume reduced as the rainfall duration extended. Based on the simulation results, each LID facility was designed and constructed in the target area. The LID practices in an urban area enable future studies of the analysis of the criteria, suitable capacity, and cost-efficiency, and proper management methods of various LID techniques.

In our society, consumers and enterprises work in cooperation for the continuous development and growth of society as well as construct effective and ethical measures. One of the representative examples are customercentered management activities in corporations, social responsibility activities, and sustainable ethical consumption that show consideration for the consumer's environment. The ethical consumption behavior of consumers becomes a virtuous circle that influences other consumer's ethical decision making by creating an ethical consumption culture. Furthermore, the cost and effort to solve non-ethical consumption problems can be solved. This research aims at aspiring the perception of consumer's ethical consumption and finding measures to increase ethical behavior. This paper further investigated the consumer's ethical consumption behavior, personality traits, perception of consumption society, and ethical judgements. For the research, a structured survey was conducted on 300 university students in Seoul. SPSS ver. 21.0 and AMOS ver. 18.0 programs were used for statistical data analysis. The results indicated differences in variables that influence consumer's ethical consumption behavior (fair trade, boycotts, and environmentally friendly products). In particular, it was evident that ethical judgements (such as the agent, personality traits, and perception consumption society) have different direct and non-direct influences on ethical consumption behavior. Strengthening the management of factors that influence measures that increase university student's ethical consumption behavior in direct and non-direct ways, providing education and improving information are believed effective in increasing ethical consumption behavior.

If a certain country or an arbitration institution hopes to keep ahead of the fierce competition in the international arbitration market, it needs to develop hardware factors, such as i) Facility and Infra, ii) Geographical Location, iii) Professional Staff, iv) Global Network, v) Capital, and vi) Arbitrators & Practitioners etc., along with software factors including i) Arbitration Rules of Law, ii) Court's Support, iii) International Convention, iv) Political Risk, and v) Education Environment, which are the most critical requirements in the development strategy for international arbitration. Having perceived the above situation, the Korean government has been working on amending the Korean Arbitration Act to reflect global advanced practice of international arbitration, and seeking to enact laws that will promote our arbitration industry and create a more arbitration-friendly environment. The KCAB is also currently revising both the domestic and international arbitration rules in accordance with these national efforts. Under these circumstances, this paper examines how major leading international arbitration institutions manage their secretariats and suggests how the KCAB can compose and manage its Secretariat to gain a competitive advantage over rival institutions.
