This study attempted to provide basic data for efficient advertising model strategies of companies and advertising agencies by verifying the effectiveness of advertising star power of retired sports athletes in Korea. Therefore, retired domestic sports athletes selected those who were aware of advertisements selected as advertising models as samples, and 206 copies of data were applied to the final analysis. Data processing used the SPSS (ver. 21.0) program to analyze frequency and verify reliability. In addition, confirmatory factor analysis, correlation analysis, and structural equation model analysis were performed with the AMOS (ver. 20.0) program, and the significance of effectiveness was verified. As a result of the study, first, star power had a positive effect on favorability. Second, favorability had a positive effect on advertisement consumption behavior. Third, star power had a positive effect on advertising consumption behavior. Finally, star power was found to have a greater direct effect on advertising consumption behavior, and favorability was verified to have a partial mediating effect.

종래의 전구식 등명기의 경우 중량이 많이 나갈 뿐만 아니라 전구의 교체시기가 짧고 전력소모가 심하다는 문제가 있었다. 또한 5mm 포탄형 저휘도 LED램프의 경우에는 수명이 길고 저전력이라는 장점이 있으나, 근래에는 해상의 배후광이 높아져 개당 소비전력이 1W(와트) 이상인 고휘도 파워 LED를 광원으로서 채택하는 등명기가 등장하고 있는 실정이다. 그런데, 이러한 고휘도 파워 LED의 경우 종래의 포탄형 LED에 비하여 광도는 매우 높으나, 소비전력이 상대적으로 매우 높으며, 그에 따라 발열이 심하다는 문제가 있다. 따라서, 고휘도 파워 LED를 채용하여 등명기의 광도를 높이는 경우에는 반드시 방열 문제를 고려해야 한다. 그렇지 않으면, 고휘도 파워 LED의 발열로 인하여 제품이 안정적으로 구동할 수 없으며, 결국에는 관련 부품의 고장이나 파손으로 이어지기 때문이다. 본 연구는 종래의 전구식 램프나 저전력 포탄형 LED램프를 대체하여 고휘도 파워 LED램프를 광원으로 적용함에 있어, 등명기의 중량을 증가시키지 않는 구조로서 보다 효과가 우수한 방열기술을 개발하기 위한 것이다.

We've already living our lives in the 21s1 century. This century, even alone, means enormous changes and innovations. Namely, we have been encountering various forms of generation changes such as digital generation, globalization generation, consumer generation, and brand power generation. Among these, there have been extraordinary changes in consumers and the environment of consumer market, and it is noteworthy of paying attention to the transition of the leader of the consumer market from producers to consumers. Such changes will affect not only all fields related to market environment but also entire fields including future products and sales. Hereupon, it is intended to foresee and analyze the trend in the consumer market of the 21st century and investigate changes in the consumer market and the environment of consumers. Also, the world has brought a single space of economy along with globalization and the era of self-imposed competition, and multi-national enterprises have emerged and, at the same time, their brands can be seen around the world. Hence, they have been trying to maintain their own power brands for the century. In the past, brand meant the name of a product in general. But, in the present, it has another meaning such that the brand itself provides psychological satisfaction and trustworthiness. Hereupon, this study intends to foresee changes in the trend of the consumer market of the 21s1 century, to ,outlook the trend of the consumer market along with study of power brand strategies, and to pursue creative strategies for power brand.

센서 노드의 여러 기능들 중 통신이 가장 많은 에너지를 소비하며, 특히 센서 노드의 RF 트랜스시버가 송수신 모드일 때 가장 많은 에너지가 소비된다. 하지만 RF 트랜스시버는 대부분 시간 동안 대기 모드 상태에 있기 때문에 대기 모드 상태에서 소모되는 에너지 총합은 송수신 모드에서의 총 에너지 소비량에 근접한다. 따라서 대기 모드 시간을 최소화하는 것이 에너지 효율 면에서 중요하다고 할 수 있다. 본 논문에서는 다중 경로를 이용하여 대기 모드 시간을 줄이는 분산 파워 스케줄링 기법을 제안한다. 제안하는 방법은 기존의 MAC 프로토콜과 함께 동작하여 에너지 효율성을 증대시킬 뿐만 아니라, 분산 및 비동기적 방식으로 동작하기 때문에 네트워크 위상 변화에 쉽게 대응할 수 있다는 장점이 있다.

In this paper, the electric vehicle (EV) and internal combustion engine vehicle (ICEV) are compared for different driving cases. The EV exhibits a lower powertrain efficiency when driven on the aggressive driving cycle than when driven on the moderate cycle. In particular, EV powertrain efficiency is low when the battery state of charge (SOC) is low, but ICEV efficiency increases when the driving cycle changes from the moderate cycle to the aggressive cycle. Based on these results, attempts can be made to increase EV powertrain efficiency. EV charging before the battery power drops to a low charging state can reduce energy consumption by 2.7% for an urban area. Furthermore, ECO driving has a more significant effect on EVs than on ICEVs.

Cutting power estimation can be used to select appropriate actuators in the design process of machine tools. Therefore, accurate estimation of cutting power is an important part of the design process. In this study, pipe cutting power is first calculated theoretically using the slotting cutting power equation and then verified experimentally. In this case, a pipe cutting machine is used to cut two pipes made of different materials. Power consumptions in the motor during pipe cutting are measured by using the embedded software, Labview, and NI hardware. The slotting cutting power equation can thus be confirmed easily comparing theoretically calculated cutting powers with experimentally measured cutting powers. The pipe materials used in this study are SUS304 and AL6N01. The specific cutting power of AL6N01 material is proposed through our cutting experiment. As a result, this cutting power can be used to design machining tools for AL6N01 material.

In the wireless sensor networks, power consumption and interference among the nodes can be reduced by using the transmission power control. Because link quality is changed by spatial and temporal effect, link failures are frequently occurred. In order to adapt to link quality variation, existing transmission power control schemes broadcast beacon messages periodically to neighbor nodes and control the transmission power dynamically. However, it can effect on the time and energy overhead according to period of transmission power control. In this paper, the dynamic method of transmission power control by the link quality variation and variable period are proposed. When a link quality is unstable, the control duty cycle is reduced and the link quality is agilely maintained. In contrast, when link quality is stable, the control period is increased and control overhead is decreased.

An Internet of Things (IoT) is a system where various "things" are connected to each other via a wired/wireless network, and where information is gathered, processed, and interchanged/shared. One of the important actors in IoT is a mobile IoT device (such as a smartphone or tablet). These devices tend to consume a large amount of power in order to provide various high performance application services; however, as the devices cannot be supplied with power all the time, efficient power management is necessary. Power management of mobile IoT devices involves complex relationships between various entities such as application processors (APs), HW modules inside/outside AP, operating systems, mobile IoT platforms, and applications. In order to develop power-efficient mobile IoT devices, a method is needed to systematically analyze these relationships and manage power based on a clear understanding of them. To address this problem, software engineering principles for the development of power-efficient mobile IoT devices are presented in this paper. The feasibility of the proposed principles have been validated in the domain of smartphone camera power management.
