This study aims to assess the attraction of foreign direct investment in Vietnamese economic zones (including industrial zones and economic zones). The main research method used are synthesis and comparison analysis based on the data collected from the surveyed group comprising of enterprises operating in the economic zones in the Middle (Chu Lai, Nhon Hoi, Dung Quat) and the Southern (the largest island: Phu Quoc). After conducting surveys, research results show that there is a difference between the assessment and the level to meet the requirements of investors with business environment, expressed through the following criteria: (1) the infrastructure; (2) quality of public services; (3) preferential policies; (4) labor; (5) market; and (6) social services. Based on the assessment of the identified criteria, this paper had suggested six number of recommendations to promote the role of attracting foreign direct investment capital into the economic zones in Vietnam: (1) implementing the "one-stop-shop" policy; (2) continuing to improve the infrastructure of economic zones; (3) prevent and ensure the security of economic zones; (4) implementing vocational training activities to improve quality of human resources; (5) development of supporting industries; (6) raising the quality of capital invested in the economic zone.

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.

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.

This study investigates the physical characteristics of indoor rest zones using the Space Syntax Method. A conceptual framework is based on analysis of design works presented in competitions(544 rest zones of 24 buildings on 7 campuses). The analysis on the unit type of rest zones showed that they were mostly available as open type, followed by semi-open type and outdoor rest places. On the other hand, by classifying the shape of whole building into traffic lines and nodal points, it was found that the buildings with 3 or more traffic lines have lower availability than others, because the buildings required more nodal points along a little higher complexity and zoning formed at increased nodal points between building masses. The analysis on the location of rest zones on traffic lines showed that hall type was most excellent in the level of availability. Finally, the analysis on the floor height showed that hall-like open rest places and outdoor places like rooftop garden functioned as a factor to enhance the integration of different spaces. In conclusion, this research will help the follow-up studies make spatial creation planning that may enhance the spatial efficiency and availability of Indoor rest zones on the campus.

A soudy on the distrobution and seasonal changes of the benthic macrovertebrates community was performed on the 5 intertidal rocky shores of Chujado in the Cheju-Channel during four seasons from March 1996 to February 1997.The macroinvertebrates identified in Chujado totally composed of 9 phyla, 18 classes, 38 orers, 147 species. The macroinvertebrates idetified according to the stations were 9 phyla, 138 species in Sinyangri(ST. 1); 8 phyla, 134 species in Younghungri(ST. 4);and 8 phyla, 131 species in Daeseori(ST. 5); The species diversities of the lower intertidal zones were higher than those of middle and upper intertidal zones, however, the seasonal appearance in number of species was not different among the stations. The vertically distributed dominant species in intertidal zone were; Nodifittorina exigua and Nerita japponica in the supralittoral zones; Monodonta labio labil and Buccinulum ferrea in the upper zones; Septifer keenae and Lunella coronata corensis in the middle zones; Purpura clavigara, S. keenae and Pomatoleios krausii in the submiddle zones; and Actinia mesembryanthemum, Tetracliata squamosa japonica and N. schrenckii in the lower zones. The intertidal community structures between Chujado and Cheju coast showed that Chujado composed of fewer number of species and lower value of species diversity and richness indices than Cheju coast.

Methods for designing the post-tensioned anchorage zones at ultimate limit state has been specified in current design codes based on strut-and-tie models (STM). However, it is still not clear how to estimate the serviceability behavior of the anchorage zones. The serviceability is just indirectly taken into account by means of the reasonable reinforcement detailing. To address this issue, this paper is devoted to developing a modified strut-and-tie model (MSTM) to predict the behavior of concentric anchorage zones throughout the loading process. The principle of stationary complementary energy is introduced into STM at each load step to satisfy the compatibility condition and generate the unique MSTM. The structural behavior of anchorage zones can be achieved based on MSTM from loading to failure. Simplified formulas have been proposed to estimate the first cracking load, bearing capacity and maximum crack width with the consideration of the details of reinforcement bursting bars. The proposed model provides a definite method to control the bursting crack width in concentric anchorage zones. Four specimens with different bearing plate ratios have been designed and tested to validate the proposed method.

The biotope network of Susung gu is characterized as dense residence zones forming its core that enable partial biotope in and around the residential zones. First, in district I, it is possible to make these zones connected to the third district. In district II, which is abundant in biotope, it is very important not to continue destoyi9ng the existing biotopes. In the case of district III, old residence zones have fill the severe gap between forests and the Sinchun river, through redevelopment, which covers more than 30% of the biotope area with large scaled linear residence areas. In the case of district IV, limited destruction of biotope and the improvement of nature areas were suggested as the alternative for preservation of biotopes. Consequently, in the construction of the biotope network in Su-sung gu, the maintenance of existing biotopes is required. Int he old residence zones, as redevelopment occurs, by maintaining biotope area of more than 30% and making the scale of residential complexes more than 1ha, it is possible for old residence zones to accomplish the role of providing important green spaces. In the case of newly developed residential zones, by reducing the rate of pavement of traffic conducts, utilizing small sized parks at the junctions and the plantation of trees along the corridors, the entire residence zones are able to accomplish the role of providing important green space. The problem houses and connecting the inner green space of the private houses with the green spaces of the streets in some areas. Futhermore, green spaces of forests must not be used for urban development. Dual planting on sidewalks, planting plots dispersed among streets and median strips must be established on road, too.

The objective of this paper is to estimate the PCE(Passenger Car Equivalents) of various vehicle types on expressway work zones. Headway samples of 5,359 vehicles were collected in 6 work zones in the Kyungbu Expressway between September and November of 1995. Average headways of 8 vehicle types based on the vehicle classification method of the Department of Construction and Transportation were calculated. A statistical test of effects of the types of the preceding vehicles were performed for the average headways between a vehicle type preceded by other vehicle types. The results show that the effects of the type of preceding vehicles are significant (exceeded 5% and 10% significance levels) and the PCEs of heavy vehicles on expressway work zones are higher than that of basic expressway section. Therefore, different adjustment factors should be applied for heavy vehicles in estimating saturation flow rates of expressway work zones. The study also derives an equation to determine PCEs of these vehicle types.
