본 연구는 CATV홈쇼핑에 관련된 충동구매행동에 관한 연구로서 특히 의류제품의 CATV홈쇼핑에 관련된 소비자 특성, 마케팅 요인이 충동구매행동에 미치는 영향에 대하여 알아보고자 하였다. 이러한 연구 목적을 위하여 부산시내 거주의 CATV홈쇼핑 방송을 시청하거나 CATV홈쇼핑을 통해서 구매경험이 있는 20~50대 성인 여성을 대상으로 설문조사를 실시하였으며, 263부의 설문지를 최종분석에 사용하였다. SPSS을 이용하여 요인 분석, t-test. $\chi$2-test, 판별분석을 실시하였고, 연구를 통해 밝혀진 결과 및 결론은 다음과 같다. 첫째, 소비자들은 CATV홈쇼핑을 탐색할 때 '애고적 탐색행위' , '상품중심적 탐색행위'로 구성되어, 소비자들은 자주 이용하는 홈쇼핑채널을 이용하여 홈쇼핑 프로그램을 즐기고 있었으며, 새로운 상품이나 상표를 보기 위해 CATV홈쇼핑을 탐색하였다. CATV 홈쇼핑에 관련된 마케팅 요인은 '촉진요인' , '제품요인' , '대금결제방식요인'으로 구성되어, CATV홈쇼핑에서 제시하는 사은품, 긴박한 상황조성, 구매재촉 등에 충동구매행동이 많은 자극을 받았으며 제품의 디자인이나 색상, 상표의 유명도 등 제품특성과 신용카드 사용여부 등 대금결제방식요인이 충동구매행동을 자극하였다. 둘째, CATV 홈쇼핑에서 충동구매집단과 비충동구매집단간에는 소비자특성에 차이가 있었으며, 마케팅요인으로부터 받는 영향력도 달랐다. CATV 홈쇼핑의 충동구매여부는 소비자의 충동성향, 마케팅자극의 촉진요인에 의해 판별되며 애고적 탐색행위, 자기통제력, 대금결제방식요인, 제품요인에 의해 판별되는 것으로 나타났다. 즉, 소비자들은 CATV홈쇼핑을 시청할 때 프로그램을 즐기며 새로운 상품을 찾았으며, 마케터가 제시하는 다양한 자극들로부터 영향을 받았다. 충동구매를 하는 사람들은 소비자특성, 마케팅자극으로부터 받는 영향에 차이가 있었으며, 소비자의 충동성향과 마케팅 촉진요인은 CATV홈쇼핑에서 패션제품의 충동구매여부를 판별해주는 중요한 변수로 나타났다.

Growth in online channels has created fierce competition; consequently, retailers have to invest an increasing amount of effort into attracting consumers. In this study, eye-tracking technology examined consumers' visual behavior to gain an understanding of information searching behavior in exploring product information for fashion products. Product attribute information was classified into two image-based elements (model image information and detail image information) and two text-based elements (basic text information, detail text information), after which consumers' visual behavior for each information element was analyzed. Furthermore, whether involvement affects consumers' information search behavior was investigated. The results demonstrated that model image information attracted visual attention the quickest, while detail text information and model image information received the most visual attention. Additionally, high-involvement consumers tended to pay more attention to detailed information while low-involvement consumers tended to pay more attention to image-based and basic information. This study is expected to help broaden the understanding of consumer behavior and provide implications for establishing strategies on how to efficiently organize product information for online fashion stores.

현재 국내에서 건설되고 있는 대부분의 아파트는 철근콘크리트 전단벽과 연결부재만으로 구성된 순수벽식 구조형식을 취하고 있다. 그러나 이러한 벽식구조의 거동은 매우 복잡하며 연결부재의 영향을 크게 받는다. 따라서 본 연구에서는 부분구조체 실험을 통하여 국내 벽식구조의 연결부재, 즉 슬래브 및 연결보의 거동을 조사하고, 보강에 따른 효과를 검토하고자 하였다. 실험결과 1) 연결슬래브의 응력은 전폭에 걸쳐서 균일하지 않았고, 2) 벽체와 커플링 작용을 하는 연결슬래브의 유효 폭은 기존의 연구에서 제안한 값과 비교하여 큰 차이가 있는 것으로 나타났으며, 국내의 아파트구조에 적용하기에는 과대평가하는 경향이 있었다. 3) 또한 연결 보에서의 X자형 보강은 에너지소산 및 연성비 증가효과가 있는 것으로 나타났으며, 펀칭현상을 개선하여 안정된 이력거동을 확보하는데 효과적인 것으로 나타났다.

In general, the interaction conditions between the discrete stones are not taken into account by structural engineers during the modeling and analyzing of historical stone bridges. However, many structural damages in the stone bridges occur due to ignoring the interaction conditions between discrete stones. In this study, it is aimed to examine the seismic behavior of a historical stone bridge by considering the interaction stiffness parameters between stone elements. For this purpose, Tokatli historical stone arch bridge was built in 1179 in Karabük-Turkey, is chosen for three-dimensional (3D) seismic analyses. Firstly, the 3D finite-difference model of the Tokatli stone bridge is created using the FLAC3D software. During the modeling processes, the Burger-Creep material model which was not used to examine the seismic behavior of historical stone bridges in the past is utilized. Furthermore, the free-field and quiet non-reflecting boundary conditions are defined to the lateral and bottom boundaries of the bridge. Thanks to these boundary conditions, earthquake waves do not reflect in the 3D model. After each stone element is modeled separately, stiffness elements are defined between the stone elements. Three situations of the stiffness elements are considered in the seismic analyses; a) for only normal direction b) for only shear direction c) for both normal and shear directions. The earthquake analyses of the bridge are performed for these three different situations of the bridge. The far-fault and near-fault conditions of 1989 Loma Prieta earthquake are taken into account during the earthquake analyses. According to the seismic analysis results, the directions of the stiffness parameters seriously changed the earthquake behavior of the Tokatli bridge. Moreover, the most critical stiffness parameter is determined for seismic analyses of historical stone arch bridges.

This paper addresses an efficient modification method that eliminates the undesirable effects of strains due to various non-conforming modes so that the non-conforming element can pass the patch test unconditionally. The scheme is incorporated in the element formulation to establish new types of non-conforming hexahedral elements designated as NHx and NVHx for the regular element and variable node element, respectively. Non-conforming displacement modes are selectively added to the ordinary (conforming) element displacement assumptions to improve the bending behavior of the distorted solid element. To verify the validation of proposed direct modification method and the improvement of element behavior, several numerical tests are carried out. Test results show that the proposed method is effective and its applications to non-conforming solid elements guarantee for the element to pass the patch test.

In this study, a numerical model for the simulation of reinforced concrete columns subject to cyclic loading is presented. The model consists of three separate models representing concrete, reinforcing steel bars and bond-slip between a reinforcing bar and ambient concrete. The concrete model is represented by the plane stress plastic-damage model and quadrilateral finite elements. The nonlinear steel bar model embedded in truss elements is used for longitudinal and transverse reinforcing bars. Bond-slip mechanism between a reinforcing bar and ambient concrete is discretized using connection elements in which the hysteretic bond-slip link model defines the bond stress and slip displacement relation. The three models are connected in finite element mesh to represent a reinforced concrete structure. From the numerical simulation, it is shown that the proposed model effectively and realistically represents the overall cyclic behavior of a reinforced concrete column. The present plastic-damage concrete model is observed to work appropriately with the steel bar and bond-slip link models in representing the complicated localization behavior.

To position precision machines accurately, linear motion (LM) guides having rolling elements can be used. For ultra-accurate positioning control of the precision machines, the understanding of the dynamic behavior of the LM guide at the macro and/or micro scales is most critical, but the research on this subject is rare. The objective of the present research is to observe the vibration phenomena of the LM guide. Bails are used as the rolling elements in this work. Several experiments show the nonlinear characteristics of the LM guide such as hysteresis behavior and force-dependent natural frequencies phenomena.

Numerical damage assessment of Van train station building consisting of three RC blocks due to 2011 Van Earthquakes by nonlinear dynamic analysis is presented. The structural model is created with rigid-end offsets and plastic hinges for nonlinear analysis. Rigid-end offsets are considered for connection areas and proposed for wall-supported elements. In wall-supported elements, walls take place in a limited part of the columns. Nonlinear dynamic analysis of the building with and without rigid-end offsets is performed by using real earthquake records and results are compared. The results show that rigid-end offsets have significant effects on the seismic behavior of the structures.

Effects of alloying elements on the pitting behavior of Ti-Al intermetalic compounds in the electrolytic soution containing Cl- were investigated through electrochemical tets and corrosion morphologies. Corrosion potential increased in the case of Cr addition to Ti-48%Al, whereas it decreased in the case of Si and B addition. The simultaneous addition of Cr and Si increased passive current density and decrosion corrosion potential. The passive current density of N addtion was higher than that of B addition in H2SO4 solution. With the addition of alloying elements, The pitting resistance decreased in order of TiAl>TiAlSi>TiAlN>TiAlB>TiAlCr and whin siumultaneous addition, it decreased in order of TiAlCrSi>TiAlCrBN>TiAlCrrN. The surface merohology after pitting test showed that the TiAl coataining Si had for fewer pits than that containing Cr and N simultaneously.
