Scooters are a popular way to get around on your own in many places, such as Taiwan, India, Thailand, etc., because they are easy to move around in, small, and cheaper to buy than cars. On the other hand, traditional scooters that run on fossil fuels put some pollution into the air and add to problems like global warming and air pollution. Switching from scooters that run on fossil fuels to electric scooters can help clean up the air in cities with much pollution. To promote the use of electric scooters, it's important to know how consumers feel about them. The current study investigates consumers' purchase intentions for electric scooters. Based on the questionnaire survey results (n = 567), we found that consumers' environmental concerns, price consciousness, and perceived subjective norms are associated with electric scooter purchase intention. Consumers with price consciousness may choose fossil-fuel-powered scooters because they consider electric-powered scooters more costly, although environmentally friendly. The study gives researchers and practitioners a glimpse into consumers' environmental concerns and subjective norms for a sustainable product.

This paper is to cluster the AMR (Automatic Meter Reading) data. The load survey system has been applied to record the power consumption of sampling the contract assortment in KEPRI AMR. The effect of the contract assortment change to the customer power consumption is determined by executing the clustering on the load survey results. We can supply the power to customer according to usage to the analysis cluster. The Korea a class of the electricity supply type is less than other country. Because of the Korea electricity markets exists one electricity provider. Need to further divide of electricity supply type for more efficient supply. We are found pattern that is different from supplied type to customer. Out experiment use the Clementine which data mining tools.

The conventional markets is badly damaged by a big fire because of no proper fire fighting management system. The cause of electricity fire is the aging and contact badness of electric equipment. The supervisory detecting system is needed to develop because the electric equipment is located to non visible and non exposing place. In this paper, we investigated the receiving and distributing board, the panel board and the fire prevention system of 17 domestic conventional markets. As a result of survey, capacity of distributing boards is mainly 600A and materials of distributing boards are synthetic resins 49%, metal 44%. ELB is mainly used as branch circuit breaker.

This paper reports the measurement results of the harmonic voltage in the distribution systems. These results were obtained from the harmonic voltage survey carried out at six industrial customers, three department stores, two apartment buildings, six substations for subway, etc. The properties in each place are analyzed.

The case where a drain cannot flow backwards, a sewer institution can be unmanageable in this, and a mad is under water momentarily by local heavy nin by the climate phenomenon in spite of not being a lowlands belt has occurred well more than recently. By the flooded mea since it is in the state which has some human bodies at hand, when a short circuit occurs in street lighting pole which is the electric institution thing of a road, the danger of an electric shock accident becomes higher. In this paper, it was going to show improvement plan for grasping the brittle factor of street lighting pole electricity facilities through the on-site survey of street lighting pole electricity facilities, and improving this.

Purpose - In China, electric vehicle industry has been increased attention as a environmental friendly transportation to solve pollution problems, and still growing to solve a technological gap issues in automobile industry. Although the interest of electric vehicle is getting bigger, there are not many studies that showing consumers' intention to purchase an electric vehicle. Because of this phenomenon, this study tried to find the factors which can affect the purchase intention of electric vehicle. Research design, data, and methodology - Drawing on the Planned Behavior Theory(TPB), this study examined attitude toward the behavior, subjective norm of environmental protection, and the influence of economic benefits on purchase intention through survey. we measure 233 Chinese samples. Results - The results showed that attitude toward electric vehicles, subjective norms of environmental protection, and economic benefits had a significant effect on purchase intention. To be specific, the consciousness of environmental protection, economic considerations, product image and its characteristic are all considerable aspects from the standpoint of Chinese consumers. In addition, we found that the higher the age group, the weaker relationship between attitude toward electric vehicle and purchase intention. Conclusion - This study suggests that diverse factors related to the purchase intention of electric car in China market and Chinese consumers. Especially, economic benefit factors, which have a statistically significant and significant influence on the purchase intention of electric vehicles, are not significant variables in the existing electric vehicle research. This result is considered to be the result of the fact that the electric vehicle is not only an automobile having an environmentally friendly factor but also a product which makes it consider the economic situation. Put together, the results of this paper give us the theoretical basis for establishing an electric vehicle marketing strategy in the rapidly changing Chinese market. Also, this paper will provide new ventures for marketing and distribution strategies for Korean companies that are looking to expand into China.

본 연구에서는 신 수요관리 기법인 DR(Demand Response) 시스템의 적용 현황을 분석하였다. 현재 전력사에서 사용하고 있는 9개의 프로그램에 대한 특성 및 적용 사례를 조사하고 분석하였다. 또한 DR 프로그램의 전형적인 실행과정을 살펴보고 DR의 효과적인 응용에 필요한 부분인 단기 부하예측의 필요와 이들의 방법에 대해서 조사하였다. 부하 예측을 위해서는 수요자의 부하 정보의 분석이 기반이 된다. 따라서 국내에 DR시스템을 도입할 경우에는 수요자의 부하 정보인 Load Profile에 대한 정보의 분석 시스템의 개발이 선행되어야 할 것으로 판단된다.

The impacts of electric service interruption to customers depend on customer and interruption characteristics. Customer characteristics include demographic aspects (residential type, and number of household members) and power supply types whereas interruption characteristics include frequency, duration, time, and day of interruption. Accordingly evaluation of these customer interruption costs is very complicated and subjective. For residential customers, customer survey method seems most appropriate because interruption impact to residential customers is intangible. In other. words, the value of housework or lost leisure due to interruption is individual. Accordingly, this paper selected the customer survey method to assess the interruption costs for residential customers.
