In this paper, to expand the use of standalone street lights, an algorithm for controlling LED energy consumption was proposed. The proposed method uses an LED module of a standalone street light divided into n zones. This is a method of reducing total power consumption by preventing the increase in power consumption due to high heat generation by weakly operating the entire LED according to the illuminance. When the amount of sunlight decreases, the whole LED operates weakly and then brightens, and unlike streetlight that act as streetlight, a method of dividing LEDs by area and limiting the number of LEDs operating according to illumination intensity was proposed. This is a way to use a lot of time with limited battery capacity by reducing the generation of heat that consumes the most power in streetlight. It is also a method of continuously changing the initial usage area to improve the total usage time of the LED substrate. As a result of the experiment, it was found that the proposed method extends the service time because it generates less heat than the conventional stand-alone streetlight.

With the recent changes in society and the introduction of new technologies, the usage patterns of parks have become diverse, leading to increased complexity in park management. As a result, there is a growing demand for flexible and diverse park management that can adapt to these new requirements. However, there is inadequate discussion on these new demands and whether urban park management policies can respond. Therefore, empirical research on how park usage patterns are evolving is critical. To address this, blog data, in which individuals share their experiences, was used to examine the spatial consumption patterns through semantic network and topic analysis. This study also explored whether these spatial consumption patterns exhibit experiential consumption characteristics according to the experience economy theory. The results showed that consumption behaviors, such as renting picnic sets and having food and drinks delivered, were prominent and that emotional experiences were pursued. Furthermore, these findings were consistent with the experiential consumption characteristics of the experience economy theory. This suggests that park planning and maintenance methods need to become more flexible and diverse in response to the changing demands for park usage.

This study examines the value, knowledge and sustainable consumption behavior of fashion consumers. The study shows that universalism/harmony, security/benevolence, power, and tradition/faith have positive effects on buying/usage behavior; however, hedonism/wealth has a negative effect. Stimulation/self-direction and universalism/harmony positively influence boycott behavior; however, power has a negative influence. Universalism/harmony and politeness have positive impacts on care/disposing behavior. Consumer knowledge about fashion related environmental problems, labor practices, ethical issues and sustainable environment knowledge influence sustainable buying/usage behavior; in addition, knowledge about ethical issues and sustainable environmental problems positively influence boycott and care/disposing behavior. Moreover, there were significant differences in values, knowledge, and consumption behavior by age.

In this paper, we suggest a usage profiles for electric home appliances. In Korea, it is published the records for total consumption of electricity in a house but the electric home appliance consumption records in a households are not. To build the data, we must collect the usage of every appliances in a house and the information of the household which live in the house. Unfortunately, it is hard to get the data because of the worry about the breach of privacy. In this paper, we make a scenarios on the electricity consumption pattern of a few households type. Based on the conjecture, we make the power consumption profiles for some home appliances. Comparison to the total electric consumption records for a house, we found our scenarios are quite reasonable.

Our country is aiming at 30% reductions in building energy consumption accounting for 39% of the total energy consumption by 2020[1]. For this purpose, the government is developing and applying the Building Energy Management System (hereinafter, referred to as "BEMS", Smart plug, etc.) while the researches on new renewable energy development. BEMS, which is applied with focus on large buildings, is inducing energy management of the entire building through energy measurement and data management, but considering its economic efficiency, it's very difficult to apply BEMS to small & medium-size buildings. Hereupon, this study intends to implement the case analysis of deterioration and economic efficiency of major equipment in buildings on the basis of electricity consumption which has been measured targeting small & medium-size buildings for a certain period by taking into account that equipment deterioration is a contributor to the increase in energy consumption.

The purpose of this study was to identify consumption behaviors among children and to examine the differences according to sociodemographic characteristics, factors related to allowance, and parents' consumer socialization function perceived by children. The data were collected from 291 elementary school students in Busan. The results of this study were as follows. First, regarding parents' consumer socialization function perceived by children, the level of child's participation and influence in consumption decision-making was the highest, whereas the level of parent-child communication about consumption was the lowest. Second, consumption behaviors among children were identified into 5 groups: impulsive consumption group, rational allowance management group, friend-dependent purchase group, planned purchase group, and effective goods management group. There were significant difference among them according to child's sex, allowance amount, allowance frequency, parents' guidance about allowance usage, parents' check after allowance usage, and 3 categories of parents' consumer socialization function perceived by children. These results imply that consumer education for parents should be developed and activated to improve consumer socialization function of parents.

This paper presents the methods to save energy by using load consumption pattern analysis. Base on the substation annual power usage data, the characteristic of the substation power consumption have investigated. With this investigation effective electrical billing condition and the control target load has been determined. Most of power usage comes from the motor car, so power system and load table of motor car were reviewed. And in the metropolitan area the peak power consumption occurs at summer or winter rush hours because of its typical characteristics. From this data control point of time are determined. Through the whole study the methode to control the power Peak consumption are proposed and prototype was designed.

Purpose: The purpose of this study is to investigate the mediating effect of conspicuous brand usage between brand experience and brand loyalty in relational perspective, and to probe the difference between the positively experienced consumers and the negatives. Research design, data and methodology: Apple iPhone, Samsung Galaxy, and other brands were suggested as consideration set to be selected from 223 Amazon Mechanical Turk respondents, and they answered the structured survey of 33 questions made by Qualtrics with 5-point Likert scale. Structural Equations Model (SEM) was employed to test the hypothesized model, and RStudio and SPSS 18 were used to analyze the dataset. Results: It was confirmed that the more consumers have positive brand experience, the more they are loyal to brand. Conspicuous brand usage can be positively mediated, and consumers who experienced high conspicuous brand usage are more likely to be loyal to the brand. Conclusions: It is noteworthy to find the mediating effect of conspicuous brand usage, and the hidden mechanism between brand experience and brand loyalty. Managers can promote positive conspicuous brand usage when consumers get in touch with product and service channels. By providing impressive conspicuous brand experience, the brand loyalty of the band can be enhanced.
