This study carried out to develop barrier-free certification program in forest trail. It is done to provide the certification system presented about certification organized, certification standard and indexes, evaluation method and operation plan. In order to develop certification program in forest trail, detailed measurement index must be developed earlier based on an accessbility, a stability, a preservation and a walking continuity. The suitable forest trail for weak pedestrian was investigated that running slope should be 1/20(5%) maximum, cross slope cannot exceed 1/50(2%) maximum and clear tread width should be above of minimum 90cm. In addition, the trail type is designed as a mixed trail system which is a combination of the loop and the line form and its distance should be 225~675m. Finally, forest trail should be manage sustainably by having regular monitoring and evaluation.

A plastic noise barrier is a structure installed to minimize noise, and it is composed of the main plate, sound-absorbing plate, and sound-absorbing material. Plastic noise barrier structures have several advantages compared to other products, such as light weight, anticorrosion, durability, easy assembly, rapid construction, and low costs. In this study, the main and sound-absorbing plates were manufactured through extrusion molding, and the sound-absorbing plate was finished with a press to improve the conventional injection molding. Extrusion molding dies and punch dies were designed, and a profile extrusion-molding system was developed. Thus, inexpensive and efficient sound-absorbing and main plates can be produced, and the noise barrier structure can be assembled rapidly. Additionally, a noise barrier structure with extended service life and excellent quality can be constructed by creating uniform free space to accommodate increased temperatures after assembly and installation.

In the global era, the tourism industry is a major profitable business, and the state and local governments are making various efforts to provide quality tourism experiences. The purpose of this study in a variety of tourism contents is to study barrier-free subway services in line with the global era, and to expand from the existing rapid, safe, and ordered transportation to the provision of high-quality comfort and all-round service experiences. This study compared and analyzed the subway service systems of Korea, China and both countries through the service design method, and presented a barrier-free subway service system to improve the user's satisfaction with the subway service system by improving the user's service experience. As a result, research results showed that 20 attractive quality attributes in 17 fields, such as convenience facilities, language issues, security equipment, and riding environment, play an important role in improving the quality and experience of subway services. In addition, through the construction of a Service Spatial Scenario, an optimized subway service system can be visualized to help understand this so that it can be used as a reference for creating a strategic application.

This study purposes to present the improvement on the index by analyzing concretely the certification and evaluation index and the actual certification acquisition focusing on the buildings acquiring the barrier-free (BF) certification. So, after analyzing the screening results of the buildings acquiring the BF certification and then grasping the general application level based on the above analysis, this study tries to present the improvement on the BF certification index by analyzing the detailed applications of the BF certification-acquired buildings and then grasping the problems on the evaluation index of the current certification system. It was analyzed that the items which applied the BF construction method generalized to the common buildings through the Act on the Promotion of Convenience in medium facilities and the items with higher distribution points were shown as high in terms of points and the acquired point level of items which influenced by the shape and condition of side and land to defile the appearance of buildings were low.

New developments in IT already impact wide segments of a young and mobile population. It is evident that applications of information technology can be of equal benefit to the aged and the disabled. `Eye-Gaze'(EGI) technology was designed for people with paralysis in the upper body. There is a compeling need for a dedicated Korean Language interface for this system. The purpose of this study is to research 'Barrier Free' software using a control group of the mobility impaired to assess the Eye-Gaze Interface in the context of more conventional input methods. TheEGI of this study uses Quick Glance System of Eye Tech Digital Systems. The study will be evaluated on criteria based upon the needs of those with specific disabilities and mobility problems associated with aging. We also intend to explore applications of the Eye-Gaze Interface for English and Japanese devises, based upon our study using the Hangul phonology.

Purpose: The number of the transportation poor has been steadily increased, and also the social perspective toward the disabled has been changed. Thus, Universal Design has been needed. In particular, the unknown majority of the transportation poor have frequently used the urban railway facilities which should reflect the ideals and principles of Universal Design. However, previous research has not focused on the study on critical factors of Universal Design. Based on this observation, the present study aims to find out Universal Design critical factors of urban railway station. Methods: This study explores the criteria of planning Universal Design in the urban railway station by analyzing and comparing the similar criteria used in both domestic areas and foreign countries. Result: Findings from this study are as follows. First, we found out the critical factors of Universal Design in the urban railway station by comparing and analyzing the similar criteria previously used. Second, this study also suggests the better directions toward the domestic criteria relating to the urban railway system. Third, we found the need of the universal standard as well as individually corresponding strategy. Moreover, we found the need of preparing the critical factors for the physical environments as well as the human service. Implications: The further research on findings of the planning criteria will have been continued on the basis of findings of the present study.

Effects of additing various types of ceramic fillers to the BZB-based glass on the thermo-chemical stability, optical reflectance, and mechanical properties were investigated. The glass system demonstrated the feasibility to host various types of ceramic fillers to form micro-composites at the processing temperature suitable for PDP systems. The optical reflectance and mechanical strength of the filler-glass composites were improved as compared to the glass itself. These results demonstrate the feasibility of applying the Pb-free BZB-based glass system as a matrix for employing various types of crystalline ceramic fillers to be used as barrier rib materials in plasma display panels.

A median barrier in the road is to separate driver and passenger the traffic flow in the 4-line over highway. In order to keep thee safety of and minimize the traffic jam in the traffic accidents, the ubiquitous intelligent median barrier system is proposed in this paper. This system is required to develop the sensor node fields in the median barrier, which detects the traffic accident using vibration sensors and wireless communication network. Free space test to sensing & receiving radio frequency, verification of middleware to report and countermeasure the accident intelligently to police and hospital are carried out.

Purpose: This study aims to find directions to improve the barrier-free (BF) certification criteria by assessing the current BF certification system, which is used as a method to improve access to passenger facilities and as a method for universal design planning, and by comparing BF certified facilities with non-BF certified facilities. Methods: This study assesses 20 BF certified facilities and 39 non-BF certified facilities, which were constructed in 2005 and onwards. The results of the assessment are compared and analyzed based on the following three categories: railway stations, urban railway stations and bus terminals. Results: The results of the analysis show that the total scores of the BF certified facilities are higher than those of the facilities that were not BF certified, indicating that the BF certification system is effective. Implication: However, there are some criteria items showing higher scores in facilities that are not BF certified than in BF certified facilities. This suggests the need to improve the BF certification criteria.
