본 연구는 소비자가 상표전환 여부를 결정한 후에 상표를 선택한다는 2단계 의사결정과정을 통하여 상표선호요인과 관성요인이 상표전환과 상표선택에 미치는 영향을 살펴보고 있다. 본 연구모델은 기존 다양성추구 및 회피연구에서 제시하는 선택의 시간의존성 개념을 적용하고 있으며, 마케팅변수의 영향을 소비자 및 소비특성과 분리함으로써 소비자의 이질적 요소를 고려하고 있다. 연구결과 상표가치와 관련된 제품내적요인과 관성구매와 관련된 제품외적요인이 상호작용하여 상표전환확률에 영향을 미치고, 마케팅변수가 상표전환단계와 상표선택단계에 서로 다른 영향을 미치고 있었다. 이러한 결과는 기존고객을 관리함에 있어 소비자 선호와 관련된 제품속성요인과 사용 및 소비특성과 관련된 관성요인을 전략적으로 관리할 필요성이 있음을 제시한다. The purpose of this study is to investigate the churning behavior of customers in mobile telecommunication market. As the mobile telecommunication market becomes mature, the importance of the switching behavior of current customers is more and more recognized. This research is to develop the churning model of current customers as a two-stage choice model where a customers first decides whether to switch or not and in the second stage s/he chooses which carrier to switch to. When current customers face the decision of whether to switch from the current service provider, there are two factors which makes the customers to switch from the current service provider. One of the factors is the brand value related to brand preference, the other is inertia tendency related to customer`s demographic characteristics and consumption/usage characteristics.

목적 : 본 연구는 한국인 BRCA 유전자 돌연변이 가계구성원들을 대상으로 암진단 및 돌연변이 보유 여부가 심리 상태와 삶의 질에 미치는 영향을 알아보기 위해 시행되었다. 대상 및 방법 : BRCA 유전자 돌연변이를 가진 13가계에서 암에 이환된 보인자 17명, 이환되지 않은 보인자 16명, 건강한 비보인자 13명이 본 연구의 분석에 포함되었다. 이 세 군을 대상으로 우울, 불안, 낙관, 유전성 유방암관련 지식수준과 삶의 질을 설문을 통하여 평가하였다. 결과 : 설문시기는 유전자 검사 후 평균 21개월(6-35)로 세 군 간의 차이는 없었다(P=0.254). 세 군 간의 우울, 낙관, 육체적 삶의 질은 유사했다. 불안은 세 군 모두에서 일반인보다 상승되어 있었다. 이환된 보인자의 정신적 삶의 질은 암에 이환된 보인자가 다른 두 군에 비해 유의하게 낮았다(P=0.009, P=0.017). 다변량 분석 결과 정신적 삶의 질에 영향을 미친 인자는 암이환여부(P=0.043)와 직업유무(P=0.008) 였다. 결론 : 같은 돌연변이 가계 내에서 돌연변이 유무는 우울, 불안, 낙관에서 심리적반작용을 일으키지 않았으나, 돌연변이 가계 구성원의 불안 수준은 돌연변이 유무에 관계 없이 높았다. 본 연구는 소규모 표본을 대상으로 한 단면적 연구이나, BRCA 유전자 검사에 수반될 수 있는 심리적 스트레스 및 그에 대한 대처법을 수립하는 데 기초연구로 의의를 가진다. Purpose: The aims of this study are to evaluate psychological impact and quality of life according to the cancer diagnosis and mutation status in Korean families with BRCA mutations. Materials and Methods: Seventeen affected carriers (AC), 16 unaffected carriers (UC) and 13 healthy non carriers (NC) from 13 BRCA mutation families were included in the study. Outcomes were compared with regard to depression (Beck Depression Inventory), anxiety (State-Trait Anxiety Inventory, STAI), optimism (Reevaluation of the Life Orientation test, LOT-R), knowledge of hereditary ovarian cancer, and quality of life (QoL) (SF-36v2 Health Survey, physical component score [PCS], mental component score [MCS]) among three groups. Result: Level of depression, optimism, and PCS were similar in AC, UC, and NC. Anxiety score was elevated in all three groups. MCS was significantly low in AC than in UC and NC (P =0.009, P =0.017). Knowledge of hereditary breast and ovarian cancer was high in AC than NC (P =0.001). MCS was significantly related to whether patient was affected by cancer (P =0.043) and has occupation (P =0.008) or not in multivariable analysis. Conclusion: From this cross sectional study, psychological adverse effect was not related to the carrier status of BRCA mutation. Elevated anxiety in BRCA family members was observed but, independent to affection and the type of genetic mutation. AC showed low mental QoL. Further effort to understand psychological impact and QoL of genetic testing in BRCA family members is required for follow-up in clinical aspects.

In this paper, the dynamic buckling criteria based on the stability of Lyapunov sense is introduced in order to analyze the dynamic buckling of latticed dome structures. As analytic models, we consider shell-like shallow truss models such as star-shape dome, span 50m latticed dome. We perform a nonlinear time history analysis and apply the dynamic buckling criteria which is introduced in this paper. Dynamic buckling loads are numerically estimated under up and down conservative forces, which are step, harmonic and seismic excitations, and compared with the static critical loads.

한상을(Han Sang-Eul),이경수(Lee Kyung-Soo),이갑수(Lee Kap-Soo) 대한건축학회 2004 大韓建築學會論文集 : 構造系 Vol.20 No.1

The purpose of this study is to analyze the equally stressed surface of tension-membrane structures by geometrically nonlinear using 4-node quadrilateral isoparametric plane stress element considering the orthotropic quality of membrane texture. The tension structures such as cable, tension membrane structure or cable dome initially exhibit the unstable condition because of no initial internal stiffness such as bending stiffness. So such structural system should install the prestress to obtain the stable state. And tension membrane structure take the three dimensional arbitrary curved surface as structural shape, and the analytical process is called Shape Finding Analysis.<br/> To verify the validity of this study, we examine the equally stressed surface of saddle and catenary shape shell structures and carry out the stress analysis.

한상만 ( Sangman Han ),최아영 ( A Young Choi ) 한국소비자학회 2015 소비자학연구 Vol.26 No.3

온라인이 정보탐색의 주요 채널로 대두하면서, 금융상품과 같이 상품의 속성 자체가 복잡하고, 전문적인 상품군에 서도 온라인에서 정보를 찾는 추세가 이어지고 있다. 본 연구는 최근 금융상품을 구매한 적이 있는 소비자들을 대상으로 이들이 30일 간 온라인에서 금융과 관련하여 검색한 이력이 기록된 웹로그를 이용하여, 금융소비자들의 온라인 정보탐색을 실증하고자 하였다. 금융과 관련된 키워드를 해당 기간 중 한 번이라도 검색한 적이 있는지 여부에 따라 금융소비자를 정보탐색자 (64.2%)와 비탐색자(35.8%)로 분류하였다. 금융상품의 경우 정보에 근거한 판단이 이뤄져야함에 불구하고 비탐 색자의 비율이 높게 나타났다는 결과를 통하여 이후 소비자문제가 발생할 시, 자기책임의 원칙에 근거하여 적절한 구제를 받지 못할 가능성이 높을 것이라고 추론된다. 금융정보탐색 여부는 소비자의 연령과 소득수준, 그리고 온라인에서의 정보탐색성향에 따라 결정되는 것으로 나타났다. 탐색자를 탐색량에 따라 저탐색자와 고탐색자로 세분화하여 로지스틱 회귀식을 다시 실시하였을 때, 본 연구에서 주목하고자 한 주관적 지식수준의 영향력이 확인되었다. 본 연구결과를 통하여 금융소비자들의 온라인 정보탐색행동을 종합적으로 이해할 수 있으며, 이를 바탕으로 금융 분야에서 소비자정보탐색과 관련한 정보제공방안 및 효과적 커뮤니케이션 방식에 대한 시사점을 도출할 수 있었다. Even in a financial decision making of consumer, online channel has been emerged as a primary information channel. In this study, we do understand consumers’ information search about financial products targeted who bargains for financial service recently. We were provided a digital panel`s web log data by an advertising agency in Korea, then used a valid sample from the dataset by whom purchased financial products in 3 months. Also we set up by 30 days as an information search period, prior to his/her contract. The purpose of this research is for understanding consumers’ information search for various financial products. The results of this study as follows. Whether consumer searches for financial information at least once or not, during the 30 days of information search stage in consumers’ decision making process, we identified financial information searcher(64.2%) and non-searcher(35.8%). Since its complicated and highly uncertain traits, financial products should be determined upon enough evidence, but the proportion of non-searcher is relatively higher than expected. It is inferred that if consumer encounters a problem, it is not be easy to be properly redeemed according to the principle of self-responsibility. In this study, logistic regression analysis was performed in order to identify the influencing factors to be a searcher from non-searcher. As a result, consumers’ income level and consumers’ online information search propensity affect those probabilities about being a searcher. As a further analysis, we classified financial searchers into two groups according to how much they search for information. An logistic regression analysis was performed again to confirm influencing factors to be a high-searcher who searches financial information over 17 times during 30 days prior to purchasing financial products, from low-searcher. We had set an ultimate goal which can identify the influence of consumers’ subjective knowledge and its risk perception, but in the previous results, none of them was significant. But regarding to how much consumer searches, consumer`s subjective knowledge is significant. As a result, consumer who perceived he/she had a short of knowledge, tried to investigate high volume of financial information. To the best of our knowledge, the results of this study will provide significant insights for the information provision on financial products and effective communication strategies for the consumer information providers such as governors.

The purpose of this study is to show the numerical method to determine the initial surface shape of membrane structures by using replacing technique trom 4-node or 3-node membrane clement to line clement. Tension structures such as fabric membrane structures and cable-net are stabilized by their initial preatress and boundary conditions. The process to find initial structural overall shape of this structures produced by initial prestress is called as the shape finding or shape analysis. One of the most important factor for the design of membrane structures is to search initial smooth surtace, tecause unlike steel or conctete building elements which resist loads in bending, all tension forces are carried through the surface by membrane stress or cable tension.<br/> To obtain the initial shape in large deformation analysis, the membrane is idealized to 4 or 3 line element using a technique with Force-Density method. and that results are compared with the theoretical value of well-known equally stressed surface.

The purpose of this study is to obtain the optimum shape of cable domes by using the real coding genetic algorithm. Generally, the structural performance of the cable domes is influenced very sensitively by pre-stress, geometry and length of the mast because of flexible system. So, it is very important to decide the optimum shape to get maximum stiffness of cable domes. We use the two models to verify the usefulness of this algorithm for shape optimization and analyze the roof system of Seoul olympic gymnastic arena and Busan Asiad cable dome as analytical model of a practical structures. It is confirmed lastly that the optimum shape domes have more stiffness than initial shape ones.

소비자의 인터넷 쇼핑몰 사이트 항해형태(Navigation Pattern)의 유형화(Typology)에 관한 연구

한상만 ( Han Sang Man ),박승배 ( Park Seung Bae ),홍재원 ( Hong Jae Won ) 한국소비자학회 2003 소비자학연구 Vol.14 No.3

Navigation patterns such as width of navigation and depth of navigation differ depending on the purpose of visit. Navigation pattern has a close relationship with purchasing behaviors of website visitors. Many researchers have shown that different shopping strategy of consumers results in different navigation patterns in the shopping mall. Thus, it is very important to investigate the relationship between consumer`s purchase behaviors and navigation patterns. In this research, we study the typology of navigation pattern using online panel data. The typology of navigation pattern was developed using such variables as stickiness of navigation, width of navigation, depth of navigation, purchase relativeness of navigation. We found that navigation pattern can be divided into four categories product purchase related, simple visit, interaction, and information seeking navigation pattern. We also found that width of navigation pattern along with stickiness of navigation and depth of navigation are highly related with purchase behaviors.
