  • Two 12 m high tubular steel lighting columns have been instrumented to determine the wind-induced fatigue loading experienced by such columns. Each column supported a single luminaire mounted on a 0.5 m long bracket. One column was planted in soil, and the other bolted through a welded baseplate to a substantial concrete base. The columns were strain gauged just above the shoulder weld which connected the main shaft to the larger base tube. Forced vibration tests were undertaken to determine the natural frequencies and damping of the columns. Extensive recordings were made of response to winds with speeds from 4 m/s to 17 m/s. Selected records were analysed to obtain stress cycle counts and fatigue lives. Mean drag coefficients were also derived from the strain data to investigate experimentally the effect of Reynolds Number.

  • Neighboring buildings which are sufficiently close to both sides of an urban street reflect sound back to the road and sound energy is increased by thses reflectors. Therefore, this study is forcussed on the prediction modeling for road traffic noise under reflective conditions. A part of a block in urban road is regared as a box. The sound energy density in the box is employed to establish prediction formulas in terms of independent variables. The variables. The validity of the proposed prediction method has been experimentally confirmed by applying it to actually measured road traffic noise data. On the whole, the agreement between measured and predicted noise levels appeared to be satisfactory.

  • This study aims to offer psychological stability and pleasure by reducing noise perception using appropriate visual information which fit to the situation and useful data for the soundscape design. The results can be summarized as follows; 1) In the Loudness evaluation of the visual information with green colored scenary showed lower evaluation rather than the other colors. 2) With the Green and Blue colored scenary with road traffic and shopping street alongside the road, lower perception of road traffic noise was showed. 3) With the White and Red scenary higher evaluation was showed than the original sound, but with the Green colored scenary lower evaluation was showed than the standard sound.

  • The objective of this study was to investigate the relationship between women's clothing westernization and the economic development in Korea. The data were obtained for the Korean women's clothes and analyzed by the linear regression method. The results were as follows: First western clothing style was adopted first for the street wear and then for the casual home wear. Second the per capita GNP as a proxy of the economic development was shown to affect the weaternization of Korean women's clothing significantly. The Korean treditional clothing was disappeared as the per capita income went up. These results support previous anthropological studies on the westernization and the economic development following industrialization. Also this quantitative study shows one way to prove Bell's hypothesis and will be of use to the economists as well as the clothing researchers.

  • This paper focuses on presenting modeling considerations and insight into the performance of typical straight, curved, and skewed box-girder bridges in California which form the bulk of the bridge inventory in the state. Three case study bridges are chosen: Meloland Road Overpass, Northwest Connector of Interstate 10/215 Interchange, and Painter Street Overpass, having straight, curved, and skewed superstructures, respectively. The efficacy of nonlinear dynamic analysis is established by comparing the response from analytical models to the recorded strong motion data. Finally insights are provided on the component behavioral characteristics and shift in vulnerability for each of the bridge types considered.

  • This paper develops an integrated optic transmitter/receiver based on ring-type WDM PON. The optic transmitter/receiver can transmit real-time images from the CCTV of a remote street without compression and transmit TCP/IP data using an optic fiber. This system can also perform remote controls of the CCTV camera. The developed optic transmitter/receiver can provide the monitoring service of an advanced image quality of remote traffic using a broadband technology.

  • The effects of secondary task on driving performance and subjective workload were investigated during a simulated driving. The driving performance was determined by the appropriateness of break timing. The driving simulator was provided by the Korea Road Traffic Safety Association. The subjective workload was tested by using a multidimensional measure such as NASA-TLX. Road was categorized into two types: narrow alley and wide street. The secondary task included pushing the number on the cellular phone, pushing radio channel, and conversing with a passenger. Seventeen subjects volunteered in the study. The data were analyzed by using SAS. Results showed that using the cellular phone and pushing channel during driving caused 3∼22% decline of driving performance and 42∼59% increase of subjective workload respectively. These results indicated that the secondary task could be potentially dangerous although there was not a significant performance decrease due to the notable increase of mental workload. In the future, if we can use a more sensitive and realistic driving simulator, the effects of secondary task under a dynamic driving situation can be investigated.

  • Functional ability is an important criterion to predict the capability of older persons to maintain independent living in the community setting. This study focused on the effect of built-environment features to ameliorate declines in functional ability and reduce the likelihood of relocation. Using longitudinal data from the Asset and Health Dynamics Among the Oldest Old (1993, 1995), relocation was analyzed for 6,225 respondents aged 70 or older. Findings are that while functional decline in household activities of daily living among older persons increased their residential moves in the community, functional declines in basic activities of daily living, household activities of daily living, and advanced activities of daily living among them increased their entrance into an institutional care facility However, they were less likely to enter an institutional care facility when their home was equipped with built-environment features such as street level ramps, special railings, modifications to allow someone in a wheelchair, grab bars or shower seat in the bathroom, and special call device or system to get help.

  • This paper analyzed the color of harbor and fishing village for the better landscape. Accordingly the aim of this study is to find out the color-scape in harbor, such as regional color and present status are to analyze with elements of design. In beginning point of development, it is to take practicable data about color planning for marine tourism. Regarding the utility of these characteristics, hue, value, chroma can be checked and design of color-scape may be possible to work out future harbor environments. This study suggests that harbor of contemporary is to be environmental harmony and regional color control. The result of this research, it is carried out that the color-scape is checked by partnership of experts, official and regional person with "agreement of landscape" to provide reasonable criteria in color surroundings. An analysis of regional color-scape is expected to use for landscape improvement of fishing village and harbor.

  • This study investigates which variables most effectively influence the positioning strategy of a brand. In addition, we test the connection between the positioning strategy of the brand and loyalty. Finally, we explore how brand experience effects the relationship between brand position and brand loyalty. To this end, this study employs the street-intercept method to collect data on consumers' perception of home appliances in Japan and conducts structural equation modeling analysis to test our hypotheses. Specifically, we find that assessments of product, service, and image have a significant impact on a brand's position which, in turn, drives brand loyalty. In addition, brand experience seems to moderate the relationship between service and brand positioning effectiveness. We also find that price promotions negatively affect brand loyalty. The research provides a consumer-centered, experiential view of how firms can develop strategies to more effectively position brands and increase loyalty among their customers. These results help both academics and practitioners to better understand how consumers assess a brand's position in the marketplace.
