Large-scaled apartment housing complex at outskirts of downtown which has direct influence on urban view concentrated on improving the space outside the complex like spatial composition of individual plan design, but neglected the contribution of urban view. However, as people's orientation toward urban areas was changed to quality from quantity, concerns on urban view have been gradually increased and planning of apartment housing has been extended to complex with view contributing to urban people as a factor composing the city in resident centered spatial composition. This study is therefore to examine the characteristics of view components of 13 apartment housing complexes at Sangmu District in Gwangju Metropolitan City and their influences on evaluating view image.

This study shows that access to urban railway station affects the development of railway station's surrounding zone (RSSZ). For instance, the value of the property in RSSZ is likely to rise on the basis of the before and after the opening of a urban railway. Urban railway system is believed as an important solution to resolve worsening transport problems in metropolitan city. Also, the opening of a urban railway line is expected to affect the change of urban spatial structure, and to have more influence on land price of RSSZ.

This study investigated the prevalence of Campylobacter spp. In poultry meat and its association with foodborne illnesses in Gwangju, South Korea. It was found that out of the 307 samples of poultry meat examined, 111 (36.2%) were infected with Campylobacter spp. Among the isolated strains, 102 were identified as Campylobacter jejuni and 14 as Campylobacter coli. The detection rate of Campylobacter spp. was higher in duck meat (63.1%) than in chicken meat (26.0%). In 5 samples (1 chicken, 4 duck), both Campylobacter jejuni and Campylobacter coli were found together. The antimicrobial resistance test showed that 99 strains were resistant to more than one antimicrobial. The most common antimicrobial resistance was seen against ciprofloxacin (84.5%), followed by nalidixic acid (82.8%), tetracycline (44.0%), and gentamicin (2.6%). The isolated Campylobacter spp. were serotyped and the results showed the presence of HS2 (20 strains), HS15 (11 strains), HS19 (9 strains), and HS8 (8 strains). Considering the findings, it is recommended to maintain hygienic practices during the cooking process and to take necessary precautions to prevent the spread of pathogenic bacteria.

Railroad, a superior mode of public transportation provides safe, efficient, speedy, comfortable and economical service, has fundamentally different characteristics from airplanes, ships and cars. Among the unique characteristics of a railroad is the fact that it operates on fixed track with multiple car trains. The subway system was first selected as the best solution to difficult automobile traffic conditions and environmental problems. Seoul subway no.1line (Jongno line) was opened for service on August 15, 1974. Seoul city has completed and now operates eight subway lines (286.7km) since 1974. At present the subways operate in Busan, Daegu and Incheon city, and are under construction in Gwangju and Daejeon city. The power source for subway trains has been electricity since 1896, and power supply systems are the third rail type and/or the catenary system. The typical catenary system is the rigid bar type. R-bar and T-bar are used in the rigid bar type of catenary system, and the two types of R-bar and T-bar are uesd in Korea also. R-bar is used only for AC 25kV power supply and T-bar for DC 1,500V. From 30 years of subway experience I would like to suggest the most economic catenary system to ensure of safety, reliability and expediency for the railway lines to be constructed and the forthcoming replacement due to the life cycle after studying and analysing the characteristics, advantages and disadvantages of R-bar and T-bar.

This study intended to propose an improvement plan to improve user satisfaction by establishing a park and green space masterplan by comparing its current status and surveying the residents' perception of green park services in two regions. The study results showed that the residents are aware of the physical and qualitative aspects of the green park environment. In addition, the quality level of the green park that people may actually use in everyday life was considered a factor for evaluation of satisfaction. In addition, it was found that the residents, who are actual users of the green park services, evaluated the satisfaction of use considering the qualitative characteristics of the green park, such as 'quality of green park' and 'availability of green park.' As a result, efforts are required to create and improve the quality of green parks efficiently based on establishing qualitative indicators, a survey of residents' perception, and quantitative analysis to develop policy directions and guidelines of the park and green space masterplan.

Purpose : The aims of this study was to identify the activation of the mirror neuron system during action observation in people with stroke and the difference between left hemisphere and right hemisphere and to provide possibility of the use of action observation as a clinical method for improving motor function after stroke. Methods : Seventeen participants were asked to observe 3 different stimulation conditions for 80 seconds. A 30 second rest period was given between stimulations. Electroencephalogram(EEG) signals from electrodes on the participant's scalp were recorded during action observation. The activation of the mirror neuron system(MNS) between the picture observation condition and action observation condition was compared with a paired t-test. An independent t-test was used to compare difference between C3 and C4 on the activation of the mirror neuron system in the action observation condition. Results : Result of paired t-test showed a significantly decreased log ratio in the activation of the mirror neuron system in the action observation condition compared to the picture observation condition. Result of the independent t-test indicated no significant differences in the activation of the mirror neuron system in the right and left hemisphere. Conclusion : The mirror neuron system showed greater activation in the action observation condition than in the picture observation condition and activation in the both hemisphere during action observation. We conclude that these findings suggest that this may possibly be an efficient clinical intervention method for improving motor function.

To suggest basic research data for a plan raising naturalness of urban park forest, the structure of forest vegetation and bird community were analyzed in four urban parks of Gwangju city. And also, their relationships were discussed. Some of the structural characteristics in the two communities were closely related to each other. Species and individual densities of birds were relatively high in Songjong and Sangmu park showing the vigorous successional progress, but were low in Anchong park with simple vegetation. The bird group that nest and feed in canopy or dead wood held occupy the highest percent in Sajik park with well developed upper layer of forest, the bird group that nest and feed in shrub did in Sangmu park with developed middle layer, and the bird group that feed in ground did in Songjong park with developed low layer. Relationship between the species diversities of forest and birds was not significant. Nevertheless, bird diversity was relatively high in Sajik and Sangmu park with the high proportion of broad-leaved trees in upper and middle layers.

Information society, introduced by the rapid progress of computer technology and communication technology, has brought us the comfort and prosperity on every aspect of human life. However, the adverse and harmful effects of it, including the ethics problems, turn out to be serious. Concerning these problems, purpose of this study is set to investigate the actual state of ethics awareness on information and communication, since ethics awareness is required more urgently than ever in this era of technology. While adolescents, who will lead the future society, comprise the majority of internet usage population in our nation, they are exposed to the harmful and risky contents in the periods during which their world view would be established. Furthermore, the problems emerging in the progress towards information-oriented society are jeopardizing the dignity and inherent value of human being, therefore causing the serious moral chaos and social problems. In this paper, the awareness level of middle school students in Gwangju City has been investigated especially in the aspect of information and communication. Based on the results, it is revealed that the efforts of government, social organization, students' parents as well as the education circles are essential. Also the proposal for improvement on the awareness level has been presented.
