Paid membership is a useful marketing method that can acquire long-term customers. This study benchmarked representative overseas memberships, Amazon Prime, Alibaba 88 Membership, and Rakuten Super Point, so that domestic shopping platform companies can refer to launch the paid membership. The membership services have in common: economic benefits, convenient experiences, and discriminatory treatment. Domestic companies should set the core customer value they want to deliver to consumers and organize the benefits so that paid membership can be operated from a long-term perspective. This study has a high practical contribution and it is necessary to conduct an empirical analysis of experts and a customer user survey in the future.

In order to secure sustainable financial resources and to attract more key supporters, today's art museums are trying to further develop individual sponsorship. The purpose of this study is to explore the direction of membership programs by considering membership as the first step for the development of individual supporters for art museums. Although it is not easy to generate substantial profits within a short period through membership, art museums can secure supporters who empathize with and participate in their mission and activities by developing individual supporters through membership. The new trends of support, which has emerged as a stream of "new philanthropy" since the 1990s, indicate that the needs and motivations of individual supporters are changing. This has great implications for the direction of the development and operation of membership programs at art museums. This study investigated the role, method, and direction of the development of individual supporters through membership by conducting a theoretical review and a case study on the membership programs and individual sponsors of art museums. In addition, the study analyzed the cases of the Cleveland Museum of Art, the Art Institute of Chicago, and the Museum of Modern Art in the United States, which have continuously attempted new approaches and improved membership programs based on a long history of membership operation and individual support, by centering on the new attributes of philanthropy, including participation and involvement, accountability, and transparency. Based on the results, implications and suggestions for Korean art museums were derived. Amid the lack of art museums' membership programs and academic research, this study has significance in exploring the direction and prerequisites for membership for the development of individual supporters.

글을 읽기에 앞서 지갑을 열어보자. 주민등록증이나 운전면허증과 같은 신분증이 한 켠에 보이고, 여러 장의 신용카드가 지갑 포켓에 꽂혀 있을 것이다. 가지고 다니기에 부담되지 않을 정도의 지폐와 각종 영수증들이 또한 한 몫 하면서 지갑 내 공간을 차지한다. 이러저러한 지갑 내용물 중에 혹시 이동통신사 멤버십 카드는 지갑에 들어 있지 않나 확인해 보자. 이번 모바일 핫토크의 주제는‘이동통신사 멤버십 카드(이하 멤버십 카드)’에 관련된 것이다. 우리가 휴대폰을 가까이 두고 사용하는 것만큼이나 늘 호주머니에 두고 활용할 수 있는 게 바로 이 멤버십 카드다. 한 때는 그저 포인트 적립카드 정도로만 여겨졌던 카드였지만, 이제는 각종 혜택이 더해지면서 상당히 쓸모 있는 카드로 자리 잡은 상태다. 심지어는 이것을 활용하지 않으면 오히려 헤픈 사람처럼 보이기까지 한 멤버십 문화가 형성돼 있다. 이 글을 통해 멤버십 카드에 대해 알아보고,포인트가 0이 될 때까지 마르고 닳도록 사용해 보자.

국내 이동통신사업자들은 자사 고객의 충성도를 높이기 위해 사용요금의 일정비율에 해당하는 포인트와 제휴사의 서비스를 제공하는 멤버십 제도를 운영하고 있다. 최근 포인트에 대한 소비자의 권리의식이 높아지면서 통신사업자들 뿐만 아니라 포인트를 발행하는 타 업종에서도 사회적 이슈로 제기되고 있다. 이에 본고에서는 이동통신사가 운영하는 멤버십 제도의 운영 실태를 살펴보고 이용자를 보호할 수 있는 방안들을 검토해 보고자 한다.

In recent years, as generative models have developed, research that threatens them has also been actively conducted. We propose a new membership inference attack against text-to-image model. Existing membership inference attacks on Text-to-Image models produced a single image as captions of query images. On the other hand, this paper uses personalized embedding in query images through Textual Inversion. And we propose a membership inference attack that effectively generates multiple images as a method of generating Adversarial Prompt. In addition, the membership inference attack is tested for the first time on the Stable Diffusion model, which is attracting attention among the Text-to-Image models, and achieve an accuracy of up to 1.00.

퍼지-베이즈 의사 결정시에 사전 분포 함수와 멤버십 함수에 파라서 퍼지-베이즈 의사 결정이 얼마나 민감하게 반응하는지 알기 위하여 연구를 진행하였다. 두 가지 퍼지 조건과 행동에서 ${\theta}$ 의 사전 분포가 정규분포와 균등분포인 경우와 표본분포가 정규분포인 경우에 대하여 민감성을 조사했다.

This research is to examine the effect of specific Sports On-line membership characteristics on Customer loyalty, the role of the important concept of the three degree of commitment(Continuance commitment, Normative commitment, Affective commitment) in relation marketing. First, discover whether professional team's customer loyalty is influenced by Sports on-line membership through the three degrees of commitment, which is an important parameter in customer relation. Second, find out the effect of currently used online membership characteristics of an off-line company on the three degrees of commitment. To achieve this aim our research team carried out an empirical study by creating an experimental hypothesis and model. The research was conducted by an online survey by 211 supporters of professional football teams. Out of the total 23 were judged untrustworthy by double answers, the empirical study was drawn out from the remaining 188. The empirical study was done by statistical analysis programs SPSS 10.0 and AMOS 4.0. The conclusion of this research is that specific characteristics of Sports on-line membership, Continuance commitment, Normative commitment, Affective commitment plays an important role as a medium in Customer loyalty.

This study was performed focusing on the telemarketers of the deluxe hotels in the five different areas as well as Seoul in order to find out the influence of the customer orientation of the telemarketers in the hotel membership operation on the telemarketers satisfaction. And the deferences of the customer orientation and the employee's satisfaction between the hotels in Seoul and in other areas were examined using the demographic characteristics as the background variables. According to this study, it reveals that the degree of the employee's satisfaction was high when their customer orientation was perceived as high. This study has a significance because it tried for the first time to research focusing on the telemarketers and to relate them to the customer orientation.

In this study, the gradient descent algorithm was used for FLC analysis and the algorithm was used to represent the effects of nonlinear parameters, which alter the antecedent and consequence fuzzy variables of FLC. The controller parameters choose the control variable by iteration for gradient descent algorithm. The FLC consists of 7 membership functions, 49 rules and a two inputs - one output system. The system adopted the Min-Max inference method and triangle type membership function with a 13 quantization level.

블룸 필터는 간단하고, 공간 효율적인 자료 구조이다. 블룸 필터는 확률에 근거하여 어떤 데이터 집합을 표현하며, 어떤 데이터가 특정 데이터 집합에 속하는 지를 검사하는 멤버십 쿼리를 지원한다. 이런 멤버십 쿼리는 긍정 오류를 발생시키지만 블룸 필터의 파라미터들을 조정하여 긍정 오류를 최소화할 수 있다. 블룸 필터는 데이터가 공유의 필요성에 의해 전체 시스템에 걸쳐 물리적으로 퍼져있는 분산 시스템과 많은 양의 데이터를 다루기 위해 데이터베이스를 사용하는 시스템 그리고 실시간으로 멤버십 쿼리를 수행해야 하는 시스템 등에서 널리 사용되고 있다. 본 논문에서는 블룸 필터에 대해 알아보고 시스템의 목적에 따라 다양한 형태로 개량된 블룸 필터들에 대해 소개한다.
