Bicycle-sharing as a product service system in the sharing economy, its characteristic is that users can go to nearby places by the public bike at any time however they don't need to have their own bicycle. However, the service quality of bicycle-sharing and satisfaction of users continuously decrease with the rapid growth number of bicycle-sharing users in China. Based on the double diamond model and from the perspective of service design, this research studies the service experience of bicycle-sharing of Chinese users, focuses on the potential pain points of Chinese users when using the public bike, and designs the optimum proposal to promote users' satisfaction. According to the research result, the research builds a new concept which can satisfy users' demand for communication, enjoyment and option during the cycling. The experience of new service system of bicycle-sharing makes humanized and subconscious interaction possible.

It is well known that data mining plays a crucial role in varities of real-world applications, by which extracts knowledge from large volume of datasets. Among functionalties provided by data mining, frequency mining over given multisets is a basic and essential one. However, most of users would like to obtain the frequency over their multisets without revealing their own multisets. In this work, we come up with a novel way to achive this goal and prove its security rigorously. Our scheme has several advantages over existing work as follows: Firstly, our scheme has the most efficient computational complexity in the cardinality of multisets. Further our security proof is rigorously in the simulation paradigm. Lastly our system assumption is general.

It is very important to establish sufficiently long and reliable annual maximum rainfall data in estimating areal rainfall quantiles of Han River Basin. The data from 9 gauging stations measured by Korea Meteorological Administration may meet such a requirement, however the number of these data sets is too small to estimate overall areal rainfall quantiles in large basin such as Han River Basin. In order to solve such a problem, the space correlations of many sites' data measured by Korea Ministry of Construction and Transportation and Korea Water Resources Corporation (the number of sites is 59) were used for modification of rainfall measure density. And areal rainfall quantiles according to each sub-basin were estimated based on regression analysis.

충주댐 유역의 미계측유역을 대상으로 공간분포를 고려한 저류함수법 기반의 유출자료를 활용하여 지역최대홍수량의 추정 가능성을 평가하였다. 유출자료의 공간확장 가능성을 보기위해 2008년부터 2017년까지의 홍수 사상 중에 8개를 선정하였으며, 적절한 비교와 NSE 검증을 위해 충주댐, 영월1, 영춘 수위관측소를 검정지점으로 지정하였다. 또한, 선정한 사상 8개의 계측유역 유출자료를 바탕으로 공간확장방법을 활용하여 미계측유역의 유출자료를 생성하였다. 생성한 유출자료로 충주댐 유역의 홍수 사상과 지역최대홍수량(QRMF) 사이의 상관관계를 분석하여 지역최대홍수량의 발생 가능성과 충주댐 유역의 K값을 추정하였다. NSE 검증결과 유역출구지점인 충주댐에서 0.53으로 만족하여 유출자료 공간확장방법을 활용한 모의유출자료 산정은 적절한 것으로 나타났으며, 모의유출자료의 특성이 실제 유역의 특성과 유사한 것으로 나타났다. 생성한 유출자료와 지역최대 홍수량($Q_{RMF}$)에 대해 피어슨 상관계수와 RMSE를 활용하여 평가한 결과 서로 매우 높은 상관관계를 나타냈으며(Pearson's r> 0.9), 홍수량 산정방법에 있어서 지역최대홍수량($Q_{RMF}$)를 사용하여 산정하는 것이 바람직한 것으로 나타났다(RMSE=1.94). 또한, 충주댐 유역에 대한 지역최대홍수량($Q_{RMF}$)의 K값은 5.298로 산출되었으며, 산출한 K값으로 전체적인 충주댐 유역의 최대홍수량뿐만 아니라 면적이 비교적 작은 소유역의 최대홍수량도 추정할 수 있었다.

With recent dispersion of sharing economy, consumption culture of sharing, instead of ownership, gets wide spread in the age groups of 20-30. Even though the market of car sharing expands rapidly, little research has been done in the area of service quality and consumer behavior regarding car sharing services. Given that future market potential gets larger, it seems highly meaningful to conduct research on customer satisfaction and their usage behavior regarding car sharing services. This paper intends to analyze main factors affecting overall customer satisfaction on car sharing services; satisfaction on service quality, satisfaction on service product, and satisfaction on service experience. Each dimension of the three factors is also analyzed to see if there is any differences between major three brands. Further analysis has been done for checking any effects of gender and usage purpose of customers on the overall customer satisfaction. Key results of the analysis show all the three main factors have significant effect on overall customer satisfaction. Each dimension of service quality has significant effect on satisfaction on service quality. Dimensions of parking lot accessability and vehicle maintenance in service product evaluation, have greater effect on satisfaction on service product. In service experience, positive affect have greater effect than negative affect on satisfaction on service experience. Women users perceive larger overall customer satisfaction on car sharing services than men users. On the types of usage purpose, Users with purpose of tour and dating/meeing friends perceive larger overall customer satisfaction on car sharing services than user without it. Further managerial implications of car sharing services are also provided.

The purpose of this study is to analyze both residential conditions and the resident impressions of the transition zone of central Daegu. The results drawn from a questionnaire survey of the residents are summarized as follows: 1) The proportion of people over the age of 60 living on a low income is high and consists mostly of retired citizens who have lived in the transition zone, in their own homes, for an extended length of time 2) The condition of infrastructure in the transition zone is very poor, however, despite the housing deterioration, the internal repair and maintenance of houses is more satisfactory than their external appearance. 3) Residential satisfaction received high ratings in every category except pollution and housing price. This response appears to stem from the easy commute of residents as well as the ready availability of facilities in the city center. 4) In terms of residential satisfaction, the residents can be divided into two groups. The first, with a high satisfaction rate, consists mainly of senior citizens who possess both personal homes and a stable living, having resided in the city center for most of their lives. The second, with a lower satisfaction rate, is composed mostly of younger residents who have lived temporarily in inexpensive rental homes. As a results, the residential area in the transition zone of central Daegu does not appear to be a problematic area like the slum of the West, but instead a stable settlement for its residents.
