  • This paper describes a preliminary investigation of contracts with a view towards automating the process of contract match-making. A novel approach based on exploiting Standard Form Contracts(SFC) is described. The approach is shown to be implementable with current technology. A second approach based on Standard Contract Clauses(SCC) which overcomes some of the limitations of Standard Form Contracts, is briefly outlined. The flexibility offered by this approach however, is accompanied by a considerable increase in the complexity of contract match-making. Both Standard Form Contracts and Standard Contract Clauses based match-making point towards an exciting area of future research.

  • 최근 추천시스템에 대한 연구는 고객에게 적합한 상품을 추천하는 것에서 진일보하여, 고객이 선호할만한 친구나 배우자를 추천해주는 인맥 연결분야로 확장되고 있다. 이러한 인맥 연결의 주요한 분야로 미혼남녀를 소개시키는 온라인 데이트시스템을 생각할 수 있다. 본 연구는 사용자에게 적합한 데이트 상대를 추천해주는 온라인 매칭시스템을 제안한다. 제안된 시스템은 기존의 상품추천 시스템과는 다르게, 추천 받는 고객뿐만 아니라, 추천 되는 상대방의 호감도를 함께 고려하여, 양자가 상호 대칭적인 만족도를 갖도록 설계하였다. 또한, 인기인에게 추천이 편중되거나, 비인기인들이 추천에서 소외되지 않고, 시스템 참여자들이 전체적으로 일관된 추천 만족도를 가질 수 있도록 하였다. 본 연구에서 제안한 매칭 시스템은 Mutually Beneficial Matching(MBM) 시스템이라 명명하였으며, 이를 다른 두 일반적인 매칭 기법인 Preference-Based Matching(PBM) 기법 및 Arithmetic Mean-Based Matching(AMM) 기법과 비교하여 성능평가를 수행하였다. 즉, 위의 세 가지 기법을 Java를 사용하여 prototype으로 구현한 후, 가상의 미혼남녀 200명의 데이터에 적용하여 비교 분석하였다. 그 결과, 제안된 MBM 기법이 PBM 및 AMM 기법에 비하여 통계적으로 유의하게 높은 상호호감도(Mutual Preference)를 보임을 알 수 있었고, 호감도의 대칭성(Symmetric Ratio)도 대부분의 경우 높게 도출됨을 확인하였다. 뿐만 아니라, 제안된 MBM 기법은 PBM 기법보다 추천에서 소외된 고객 수(Number of Outsiders)가 적어서, 매칭 pool안의 사용자들에게 전체적으로 호혜적이고 일관된 추천서비스를 제공할 수 있을 것으로 기대된다.

  • Color is an important factor in dental esthetics. Application of natural tooth color will not fail to produce pleasing results. But a standardized method of shade matching has not been adopted. If we are to overcome the color matching problem in dentistry, an understanding of the nature of color and light is essential. The purpose of this study was to compare the effects of different light sources and different background colors on the ability of observers to correctly match shades of artifical teeth. And observation was made to determine if the time spent in making a shade match was a factor in the correctness of the response. A test method was devised and 50 individuals made observations which were recorded and analyzed. $X^2$-test gave results indicating that the time factor had no effect on the response made. An analysis of variance showed the following effects significant at the five percent level; (1) light source (2) background color (3) subject. The following conclusions can be drawn from this study; (1) The time spent in making shade selection is not a factor in the correctness of the selections. (2) The light source used is an important factor in matching tooth shade; and there is no significant difference between the light sources in shade matching. (3) Under the conditions of this study, the greatest accuracy in shade matching was obtained on the brown background.

  • Globally, medical tourism draws attention as a national growth engine industry, and is actively expanding. Current medical tourism leans towards large hospitals making it difficult to attract new users. Users collect the information for medical tourism through various paths in order to receive medical consultations and customized tour services. To expand medical tourism to small and medium sized hospitals, it is necessary to have customized medical consultations, tours and interpreter services, which are the key elements of medical tourism. This paper suggests services that users can use to match medical consultations and find tours and interpreters they want at the same time. This paper suggests ways to provide integrated services based on the information experienced by users, combining the required items from the perspectives of each user, hospital and guide. To match the content provided by hospitals and guides with experience information from users systematically, this study suggests the convergence plan for a service model that can match the experience information between users and hospitals, between users and guides and between hospitals and guides systematically by operating the data in the universal container.

  • Recently, the growth of e-commerce in Saudi Arabia has been exponential, bringing new remarkable challenges. A naive approach for product matching and categorization is needed to help consumers choose the right store to purchase a product. This paper presents a machine learning approach for product matching that combines deep learning techniques with standard artificial neural networks (ANNs). Existing methods focused on product matching, whereas our model compares products based on unstructured descriptions. We evaluated our electronics dataset model from three business-to-consumer (B2C) online stores by putting the match products collectively in one dataset. The performance evaluation based on k-mean classifier prediction from three real-world online stores demonstrates that the proposed algorithm outperforms the benchmarked approach by 80% on average F1-measure.

  • 추천시스템은 사용자들의 관심을 끄는 아이템을 그들이 보다 쉽게 찾도록 도와주거나, 그들의 기호에 기반하여 의미 있는 아이템들을 제공한다. 지금까지 가장 성공적이었던 협업 필터링 기반 추천시스템은 다른 사용자들의 의견을 참조하여 추천을 원하는 사용자에게 추천을 한다. 즉, 아이템들에 대한 사용자 기호를 나타내는 다른 사용자들의 평가정보가 추천을 위한 정보원으로 사용된다. 이처럼, 협업 필터링 기반 추천시스템이 사용자들의 기호만을 이용하도록 설계되었지만, 다른 정보를 이용하면 추천시스템의 성능과 정확도를 높일 수 있을 것으로 사료되어, 본 논문에서는 유사 정도와 인구통계학 정보를 이용한 협업 필터링 기반 추천시스템을 제안한다. 이런 추천시스템에서는 평가정보가 계속적으로 누적되기 때문에, 추천시스템의 정확도를 유지할 수 있는 한, 사용하는 데이터의 양을 줄이는 게 중요하다. 본 논문에서는 유사 정도와 인구통계학 정보를, 사용할 데이터의 양을 줄이기 위한 기준으로 사용하여 자연스레 시스템의 성능을 향상시켰다. 본 논문에서는 실험을 통하여 유사 정도의 사용이 추천시스템의 정확도를 높여주었고, 특정 인구통계학 정보의 사용도 추천시스템의 정확도를 높였음을 보였다.

  • This study aims to analyze consumers' purchase decision-making process of buying avatar fashion items on the Metaverse platform. Drawing on the connection between the self-expression tendency of the MZ generation and that of avatars in the Metaverse, this study uses a qualitative research method to analyze how consumers express their self-image through the appearance of their avatars. Unlike previous studies on the clothing purchase decision-making process, this study shows that purchasing and consumption behavior involve the following six stages: recognizing desire, collecting information, evaluating alternatives, making purchases, evaluating the consumption, and post-purchase action-taking. In the first stage of the purchase decision-making process, consumers' desire arises with self-image expression and confirmation. In the second stage, consumers have a high tendency to shop in the best item category. In the alternative evaluation stage, consumers tend to seek items that match their highest standard while considering their personal preferences. In the fourth stage, when making actual purchases, unplanned purchase behavior often occurs along with an active practice of alternative evaluation. In the fifth stage, the evaluation of the consumption shows that consumers achieve satisfaction by applying a style to their avatars that they are unable to try in the real world. In the last stage, consumers often use their purchases to communicate their various styles with other online consumers. Therefore, we conclude that the online purchase decision-making process differs from the offline process as it is divided into six stages.

  • In order to mass-customize clothes, it is essential to take into account individual body shape using computerized 3D body models. This paper describes the development of an interactive body model that can be altered to match individual body perimeter, postures and depth for the purpose of computerized pattern making. Construction of the body model requires the extraction of necessary points, adjustment of coordinate points, linking of points by spline curves, control of section lengths and selectability of various hip types. Front to back depth of the model is adjusted by scaling ratio. We had a great result for controlling perimeter, posture and depth of body shapes. The results support the adaptability and potential usefulness of the posture and depth adjustable body model.
