This study aimed at reviewing the case examples of environmental assessment of development projects within management zones, identifying problems and improvement opportunities and suggesting the direction of environmental assessment for management zones that are increasingly segmented Findings showed that first, the assessment of environment soundness in management zones must incorporate the national land environmental map and wide-area ecological axes established by the Ministry of Environment. Second, regarding development activities in management zones, rather than an issue of simply destroying natural environment in a development site itself during a development period, an issue of permanently isolating ecosystems from surrounding areas in a mid/long-term perspective and continually polluting water in mid-stream/upstream regions where sites are located must be considered. Third, in the case of development projects with vast areas, existing plant communities will be disturbed and the naturalness of vegetation will gradually decline due to foreign tree species introduced for landscape architecture. Therefore, creating buffer forests at forest boundaries and planting native tree species that are same as nearby tree species must be examined. Last but not least, when assessing the environmental soundness of management zones, it would be crucial to comprehensively review the environmental, social and locational features of management zones, including surrounding areas, and set the direction of environmental assessment accordingly.

The legal basis for the systematic prevention and response to landslide hazards, and the rehabilitation of landslide-hit areas, was established through the amendment of the Forest Protection Act in August 2012. The most noticeable amendment to the Act is the inclusion of clauses associated with the designation and management of landslide-prone zones (including debris flow-prone zones). In this paper, we (1) introduce the clauses related to the designation and management of landslide-prone zones that were included in the amended Forest Protection Act, (2) examine their significance by reviewing the present status of related domestic laws and structural countermeasures such as sediment check dams for sediment-related disaster prevention, and (3) suggest the future directions of the procedure for the designation and cancellation of such zones, and their maintenance and institutional aspects. The establishment of an institutional device for the designation and management of landslide-prone zones has great significance in the aspect of (1) the establishment of a comprehensive management and prevention system for potential landslide-prone zones in forested areas where the hazard risk has been poorly recognized as compared with the flood risks in lowlands, and (2) the establishment of the basis for overcoming the limits of structural countermeasures according to limited budgets. To develop the designation and management system for landslide-prone zones, not only must present problems be addressed, but a cooperation system between the administration and local residents must also be established.

The revision of domestic laws is in progress according to the UN Convention on the Law of the Coastal Zone Management . Along with it, the governmental policies related to maritime environmental preservation, especially around coastal zones and public works have been promoted based on enviornment, swiftly changed from the old function-based style. Therefore, this report will point out the important aspects which should be considered whenever there is any project on the coastal zones, suggest and classify projects of reviving the nationwide coastal zones, and show how to planning , check and evaluate the necessary technologies for reviving the coastal zones. This research will track down the coastal zone management method based on the natural enviornment as one of the necessary process to check the coastal zone enviornment for effective operating of the coastal zone management equipment method, starting on August 9, 1999, and report the technologies related with it.

Ansan urban nature park is 197.8ha and located in Seodeamun-Gu of Seoul. Flora of Ansan consisted of 141 species, 76 genera, 40 families in woody plants. This study was conducted to analyze the natural environment and establish the park management plan with ecological approach. The result of this study is summarized as follows. 1. The short term plan shall be performed in six vegetation management zones; Robinia pseudoacacia community zone, Sorbus alnifolia community zone, Quercus acutissima community zone, Populus ${\times}$albagrandulosa community zone, Pinus densiflora community zone, and landscape planting zone. Pinus densiflora and landscape planting zones shall be managed artificially, the others managed with ecological approach. 2. The long term plan shall be performed in four vegetation management zones; Robinia pseudoacacia community zone, Quercus spp. community zone, Pinus densiflora community zone, and landscape planting zone. Pinus densiflora and landscape planting zones shall be managed artificially, the others managed with ecological approach. 3. Because soil of Ansan is acidified and the soil disturbed growth of plants, the improvement of soil is necessary. The fertilization shall be performed in three zones; evergreen confierous tree zone(ex. P. densiflora), Quercus spp. zone, and the other deciduous tree zone(ex. R. pseudoacacia).

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.

Backgrounds: The objective of school zones was to define protective areas and to keep children vulnerable to traffic accidents from the risk. The current "Rules on the Designation and Management of School Zones" included provisions on the installation of traffic safety facilities and road facilities, but they were not sufficient for children's traffic safety and there were many difficulties in applying standards to the fields. Purposes: With these problems to be solved, the present study surveyed the current state of safety facilities in school footpaths and school zones around elementary schools and suggested plans to improve them. This study studied various factors like the physical environment and the safety facilities in the school zone. Methods: The present researcher visited four elementary schools selected for this study, and surveyed safety facilities in the school zones around the elementary schools using a schedule prepared by the researcher. Results: According to the results of the case study, all of the four schools were designated as school zones, but the designation appeared nominal without sufficient safety facilities that can ensure children's safety. Based on the results of the survey, suggestions were made to improve traffic facilities in school zones and school footpaths as well as safety guidance.

Access-control of hazard zone in a steel manufacturing industry is studied in terms of safety management. Based on the results of risk evaluation for hazard zone, three risk zones with low, middle and high level are categorized. These zones have different color door and locking shape depending on their risk levels. At the high level, red door and key-based locking system are employed to accessed-controled path. Furthermore, tagout, lockout, interlock system for emergency stop, warning and flashing are also introduced. New standardized procedure of access-control for various hazard zones, which could help to greatly contribute to the prevention of accidents in advance, is proposed considering the risk level and the condition of given hazard zones. The standardized procedure of access-management suggested in this study will take an effective role as one of safety guide lines for hazardous workshop of manufacturing industries.

An inappropriate space zoning plan causes the unnecessary transportation of construction material and equipment among work areas and increases the disorder of work space. Space zoning is an essential operation management technique which contributes to reduce the process and/or operation idle-time. This paper introduces a method that computes the idle-times between construction operations (or processes) by using Web-CYCLONE. It allows computing with idle-times that affect the construction productivity. Using the idle time between operations and between processes, it computes the optimal number of zones and finds the optimal combination of zones that minimize the idle times. The method contributes to minimize the idle times relative to the operation schedule using complete enumeration. This paper presents the system prototype in detail. A case study is presented to demonstrate the system and verifies the validity of the model. It allows a project manager to establish space zoning plan that effectively segregates a project into optimal number of construction zones and to assign the constrained resources (e.g., laborer, equipment).

With increased chemical and economic development activities in upstream areas, the amounts of pollutants released have increased, and as such, so has the need for positive management of water supply source areas. Although more than 90% of the water supply sources in Korea depend on direct intake from surface water, the interest in indirect intake, such as riverbank filtration water, has recently risen, with some local governments currently undertaking indirect intake. Even in cases of indirect intake, water supply source protection zones need to be assigned for the comprehensive control of pollutants. To establish water quality protection zones for indirect intake, the scope of the protection zones needed to reflect the hydrological features of the water-bearing deposits of each site. Water source protection areas were estimated and presented as the 1st (within a 100 m radius from an intake well) and 2nd (within a 2 km radius from an intake well) zones. The 1st zone was more sensitive; hence, the installation of various facilities should be prohibited, and the area should be regarded as off-limits. For the 2nd zone, appropriate management should prohibit and restrict activities already present in the water source protection zone.

Purpose: The purpose of this study is to analyze the Safety and Logistical Distribution Management system in Thailand's Highway Work Zone based on data from Logistics drivers. Accidents in highway construction zones have caused enormous casualties in Thailand yearly. Statistical data shows evidence of correlation between numbers of accidents and drivers' recklessness. Research design, data, and methodology: In this study, we conducted an in- depth interview with 414 logistics drivers and highway construction workers in Khon Kaen province, Thailand. The data was collected based on 63 questionnaires aiming at capturing factors contributing to the risk of safety and cause of accidents in logistic infrastructures such as Highway work zone. Results: The result reveals two significant factors affecting safety in highway work zone, which includes construction environment and safety management system. Moreover, the result shows that feeling of afraid and confused while driving within the construction zones significantly affecting driver's risk of having an accident. Conclusions: The findings of this study offer that a strategic planning and evaluation of the logistics drivers' satisfaction and construction workers' participation to mitigate highway accidents at construction zones and that drivers' knowledge and perception toward construction safety management plays a significant role in preventing highway accidents at the construction areas.
