The retail store, which appears in various ways of the modern city, is the architectural result that the merchandise is finally delivered to consumers. The relationship between the commerce based on manufacturing and distribution and the retail store as urban architecture can be understood not only from the viewpoint of economics and business administration but also the problem of the formation of urban history and urban organization. The modern industrial development in Korea had been progressed by the state led, as the manufacturing and distribution developed in turn. This social and economic situation influenced the formation of the retail store of the city. This is different from the West, which the development has been conducted together. The cosmetics sales space, which is the subject of this study, has changed in various forms from the 1960s to the 1990s. Cosmetics brand retail shop is a corporate brand-based space, but paradoxically, it has a historical characteristic of urban architecture in that it is branding city street. This specificity of Seoul is unexplained by the development process of the Western and does not exist as a physically huge or special construction sometimes. However, it operates as a urban architecture in Seoul where the complicated.

This paper proposes a real-time algorithm of multiple task planning and trajectory planning for drone swarms. The multiple task planning is based on the CAPT (Concurrent Assignment and Planning of Trajectories) algorithm, and especially, it plans multiple task considering task priority and a required minimum number of agents for each task. Also, the trajectory planning adopts minimum snap trajectory generation to produce dynamically feasible trajectories for drones of multi-rotor types, and it guarantees collision avoidance between neighboring agents in free aerial space. The proposed algorithm is implemented in the ROS (Robot Operating System) environment, and simulation results show feasibility and real-time capability of the proposed algorithm.

A broadband tunable absorber is designed and fabricated. The tunable absorber is comprised of a dielectric-metaldielectric multilayer and plasmonic grating. A large size of tunable absorber device is fabricated by nano-imprinting method. The experimental results show that over 90% absorption can be achieved within visible and near-infrared regimes. Moreover, the high absorption can be controlled by changing the polarization of incident light. This polarization-sensitive tunable absorber has practical applications such as high-efficiency polarization detectors and transmissive polarizer.

This article describes a path planning algorithm for fixed-wing UAVs when a real terrain should be considered. Nowadays, many UAVs are required to perform mission flights near given terrain for surveillance, reconnaissance, and infiltration, as well as flight altitude of many UAVs are relatively lower than typical manned aerial vehicles. Therefore, real terrain should be considered in path planning algorithms of fixed-wing UAVs. In this research, we have extended a spline-RRT* algorithm to three-dimensional planner. The spline-RRT* algorithm is a RRT* based algorithm, and it takes spline method to extend the tree structure over the workspace to generate smooth paths without any post-processing. Direction continuity of the resulting path is guaranteed via this spline technique, and it is essential factor for the paths of fixed-wing UAVs. The proposed algorithm confirm collision check during the tree structure extension, so that generated path is both geometrically and dynamically feasible in addition to direction continuity. To decrease degrees of freedom of a random configuration, we designed a function assigning directions to nodes of the graph. As a result, it increases the execution speed of the algorithm efficiently. In order to investigate the performance of the proposed planning algorithm, several simulations are performed under real terrain environment. Simulation results show that this proposed algorithm can be utilized effectively to path planning applications considering real terrain.

In this paper, we propose a three-dimensional path planning algorithm for a large-scale swarm. The proposed algorithm is based on the Eulerian approach that controls spatial characteristics which is an agent density vector. This algorithm has three phases, which are environment abstraction, optimal transport, and collision avoidance, respectively. The algorithm can be applied to a largescale swarm of 1000 agents or more, and it guarantees collision avoidance between obstacles existing in the given flight environment and the surrounding agents. We carried out simulation using two scenarios, and as a result, it was confirmed that the proposed algorithm is suitable for three-dimensional path planning for a large-scale swarm.

본 연구는 일중독이 조직에 미치는 영향을 알아보기 위해, 일중독 유형을 성취지향적, 열정적, 강박적 일중독으로 구분하여 일생활균형, 조직몰입, 직무만족과의 관계를 분석하였다. 가설검증을 위해 요인 및 신뢰도 분석, 상관관계 분석, 회귀분석, 공분산구조분석, Sobel 분석을 실시하였다. 분석결과는 다음과 같다. 첫째, 세 가지 일중독의 유형 모두 일생활균형에 부정적 영향을 미친다. 둘째, 일생활균형은 전반적으로 조직몰입과 직무만족에 긍정적 영향을 미친다. 셋째, 성취지향적 일중독은 조직몰입에는 긍정적 영향을 직무만족에 부정적 영향을 미치는 것으로 나타난데 반해, 열정적 일중독은 직무만족에 긍정적 영향을 미치고, 강박적 일중독은 조직몰입과 직무만족에 부정적 영향을 미친다. 일중독 유형에 따라 조직몰입과 직무만족에 미치는 영향이 다르게 나타난 것은 일에 대한 태도를 유형화하여 유형별로 다른 동기부여 전략을 구사할 필요가 있음을 시사한다. This research aims to analyze the relations among work-life balance, organizational commitment and job satisfaction by dividing into performance-oriented, enthusiastic and obsessional workaholism to examine how workaholism impacts on the organization. This study utilized factor and reliability analysis, correlation analysis, regression analysis, covariance analysis, and Sobel analysis to verify the research hypothesis. The findings indicates that all types of workaholism are effective in the work-life balance, while the work-life balance has a positive effect on organizational commitment and job satisfaction. Additionally, performance-oriented workaholism has a positive influence on organizational commitment, but negative influence on job satisfaction. However, enthusiastic workaholism has a positive impact on job satisfaction. Lastly, obsessional workaholism was found to have a negative effect on both of organizational commitment and job satisfaction. Based on this study, it suggests that organization needs to show different motivation strategies according to typological approach to employee’s job attitude.

The expansion of the online market is expected to change the purchasing environment. The purpose of this study is to examine the difference in the moderating effect of each characteristic on perceived quality and purchase intention according to the group according to product involvement and purchaser age. The first step is to identify the characteristics of online information sources and social media platforms through a literature review. Next, when perceived quality affects purchase intention, we verify the moderating effect according to the characteristics of online information sources and social media platforms. The moderating effect is verified at the stage by dividing it into a group according to product involvement and a group according to age. The following results were confirmed throughout the study: First, perceived quality significantly affects purchase intention. Second, in the relationship between perceived quality and purchase intention, the influence of the moderating effect is different depending on the high-involvement product and the low-involvement product. Third, it was confirmed that there was a difference in the moderating effect of online information sources and social media platforms in the relationship between perceived quality and purchase intention according to age. This study intends to increase consumers purchase intentions by identifying specific age groups and product groups of involvement and establishing strategies suitable for the characteristics of online information sources and social media platforms.
