This study examines the impact of dance in dance viral convergence advertising. Dance viral images appeal to a wide range of consumers. Especially, Dong-A Otsuka's Oronamin C ad released in 2015 achieved great results and won an advertisement award with an addictive CM song and dance. So this study selected the advertisements of Oronnamin C from 2015 to 2017 for its analysis. The theoretical background is analyzed through the element of dance choreography and characteristics. The results of the analysis of ads showed that they were made of simple and repetitive situations, which are the characteristics of dance comic style. There was little shift in space, choreography was mainly based on one straight line but with a crowded group, circle and V-shape appeared. Spatial composition was mainly first-person point of view. In the dance viral ads , dances were composed of short rhythmic phrases with simple and repetitive elements, eliminating complicated elements.

Since discount stores should be operated mostly by the non-human resources regarding the natural characteristics of the business, it is possibly said that their physical environments have been extremely significant. This study attempts to develop the measurement items and construct factors which are especially relevant to the physical environments of the discount stores and examine how the customer satisfaction and intention influence on these construct factors. These provide a useful framework for understanding the problems of measuring and evaluating the physical environments of discount stores. The final factor analysis for each construct factors resulted as four factors, and two categories(amenity and convenience) represented the characteristics of same construct such as the visibility. Then convenience is eliminated, and an attempt was made to add the new variable what is called the visibility. As a result, final construct factors that would be used in this study are made of four items; amenity, accessibility, POP and visibility. This study utilizes the LISREL 8.12 to evaluate the validity of factor structures and measurement model involving the physical environment in discount store. Finally, for the success of the projects, I think that it is necessary to provide comprehensive efforts continuously.

Recently, engineering problems such as long-term settlement, differential settlement, and the resultant structural damage, have been frequently reported at construction sites. Use of Sand Compaction Piles(SCP) and Granular Compaction Piles(GCP) are good at remedying existing problems, improving bearing capacity and promoting consolidation. However, such compaction piles have the potential for clogging, which would limit their usability. Investigations into the potential for clogging in SCP, GCP, and GCP mixed with sand has not been thoroughly conducted and is the objective of this current study. Large scale direct shear tests were performed on sections of SCP, GCP, and sand mixed GCP to evaluate bearing capacity. Discrete Element Method analyses were conducted with PFC3D and Finite Element Analyses were conducted with MIDAS GTS to propose an algorithm to help reduce clogging in the granular compaction piles. Results from the large scale direct shear test and multiple simulations suggest a 70% gravel and 30% sand mixing ratio to be optimal for bearing capacity and reducing clogging.

In this paper a constitutive model for large cracks in concrete and other brittle materials subject to dynamic and cyclic leading is presented. The suggested model is based on the plastic-damage model for cyclic leading. A numerical formulation based on the three-step return-mapping algorithm for the proposed large crack model is also present. The numerical examples show that the present algorithm works appropriately under dynamic leading and should be used in large crack problems to prevent excessive tensive plastic strain development causing unrealistic results.

The shape of a iron bed supporting a permanent magnet in a large-sized motor is a important factor for determining the coupling strength with the yoke. In a large-sized motor, there is a difference in electromagnetic force with the yoke depending on the shape of the iron bed. In this paper, we show the differences and problems by calculating the electromagnetic force between the double bed and the single bed through the virtual air gap, and show that the single bed is superior in terms of the binding force. It is also shown that the binding force between the bed and the yoke is improved by carving the groove shape under the bed.

Precast concrete(P.C.) large panel structures have usually weaker stiffness at joints than that of monolithic in-situ reinforced concrete structures. But structural designers do not in general take into account this characteristics of P.C. large panel structures and use the same analytical models as for the monolithic structure. Therefore, the results of analysis obtained by using these models may be quite different from those actually occurring in real P.C. structure. In this study, the change in force and stress distribution and deflections of structure caused by applying lower shear stiffness at vertical joints are investigated through trying several finite element modeling schemes specific for P.C. structures, Finally, for engineers in practice, a simplified model, which takes account of the effect of lower shear stiffness at vertical joints, is proposed with the understanding on possible amount of errors.

기후변화의 영향으로 폭우발생 빈도 및 강도는 최근 들어 급증하고 있다. 빈번히 발생하는 대형 폭우에 의해 도시는 홍수와 산사태 등 많은 자연재해가 발생하고 있다. 최근 도시에서 발생한 대형 폭우재해의 1차적인 원인은 도시방재시설물 설계빈도를 상회하는 집중호우이지만, 방재를 고려하지 않은 도시계획 및 설계가 피해를 가중시킨 것으로 판단되고 있다. 대형화 및 일상화되어가는 폭우재해에 적응하기 위해서는 하수관거, 제방 등 전통적인 방재시설물 설계기준을 상향조정하는 구조물적 대책뿐만 아니라, 도시의 토지이용, 공원, 녹지, 광장, 도로 등의 구성요소를 활용하여 우수유출 저감 및 지연시켜 최대홍수량을 낮추는 비구조물적 적응방안도 필요하다. 기후변화에 따른 폭우재해에 도시차원에서 효과적으로 적응하기 위해서는, 다양한 폭우재해 적응 도시계획 및 설계기법을 개발하고, 그 효과를 시뮬레이션 할 수 있는 시스템 개발이 필요하다. 본 연구에서는 기존에 개발된 홍수 및 산사태 관련 시스템들과 연계하고 정부의 다양한 부처에서 구축된 DB를 최대한 활용하여 폭우에 의해 발생하는 도시 홍수와 산사태 피해지점과 피해 영향권을 분석뿐만 아니라 폭우재해 적응 도시계획 및 설계기법을 효율적으로 적용할 수 있는 관리지역을 도출하고, 관리지역에 폭우재해 적응 도시계획 및 설계기법 적용시 효과를 분석할 수 있는 기후변화 폭우재해 적응 도시조성 시뮬레이션 시스템 개발방향을 제시한다.

Some major properties such as a heat release rate have been measured experimentally for the validation of fire model and the clarification of fire phenomena as the study is more rigorous recently. Although the reduced-scale experiment also provides the basic data and the physical understanding in fire study, it is not enough to explain real fire problem directly because there is no exact analogy theory between a real fire and the reduced scale model. Therefore, large cone calorimeter have been built and used in a few foreign countries for the measurement of large scale fire. This paper addressed the theoretical background and the description of key features in the design of the facility. It will be a useful guide for implementation of the large scale cone calorimeter in the future.

정보가전기기들의 대형화 제품개발 및 생산에 따른 전력소모가 극대화 되어있는 현실에 에너지소비를 줄이기위한 많은 연구들이 진행되고 있다. 그 중 LCD TV 분야는 전체 전력소비의 약 70% 이상이 Back-light에 의해 소비되므로 효율석인 Back-light 설계에 관한 관심이 증가하고 있다. 근래에 전통적인 CCFL 방식의 flack-light 구조에서 LED Back-light으로 점차 대체되어가고 있으며, 이러한 변화는 앞으로도 지속적으로 증가하기라 예상된다. 따라서, LED Hack-light의 효율적인 선력관기는 산업적 측면에서도 매우 주요한 부분이라 할 수 있다. 본 논문은 대형 TV의 에너지효율을 높이기위한 LED Rack-light 구성에 관한 요소들을 관계를 기술하고, 특히 Back-light 밝기제거를 통한 효율적인 전력관리를 실현위한 다채널 구동제어신호 생성에 관해 설명한다.

육계사의 대형화에 따른 최적환경조성의 중요성이 대두되고 있어서, 이에 따른 적합한 시설환경이 더욱 요구되고 있으나 적정환기가 이루어지지 않아 육계의 생산성 향상에 어려움이 많이 있다. 국내 대형육계사내 최적환경제어를 위한 주요환경변수의 기초자료가 매우 부족한 실정이다. 최 등(1999)은 육계사의 대표적인 여러 계사구조에서 온도, 습도, 유해가스농도 및 육계의 체중, SDS 발생율 및 폐사율, 도체이상 발생율 등을 조사하였다 황보 등(2002)은 3(W)$\times$5(L)$\times$3(H)의 무창계사에서 환경요소 중에 온도, 습도, 공기유속을 분석하여 환경효율을 조사하였다. 대부분의 관련연구들의 자료로는 계사내 환경 균일성, 적정성, 안정성 등을 효과적으로 분석하는 것이 어려웠다.
