  • The purpose of this study is to establish the principles of an arrangement planning for children's playgrounds which can be contributed to offer the recreation opportuqities to all urban children equally. The study is specially focused on the service radius and the inducement rate in children's playground. The data in this study were made into field survey, dividing the park users into preschool children (below 6- year-old)and school children (7 to 12-year - old), through six sampling places in Taegu City. The results are summarized as follows : The using distance was becoming shorter according as the dencity of population was becoming high. There wart 75% of the users to service radius 250m prescribing in the present City Park Law. The service radius of preschool children was 260m and that of school children was 300m in average. To investigate the effects of several attributes on the inducement of children's playground, three of six children's playgrounds were selected based on three attributes of those which were width of area, percentage of green coverage and the pattern of facility arrangment. Of three children's playgrounds, Sankyok 3- dong which had the highest percentage of green coverage, the greatest width of area and the corner type in the arrangement was a slight tendency to become the same in the inducement rate of the two age group. In the using pattern of this Sankyok 3-dong. preschool children usually used a play facility, on the contrary, school children showed the active play pattern by using space.

  • To supply precise marketing and differentiated service for the electric power service department, it is very important to predict the customers with high sensitivity of electric power failure. To solve this problem, we propose a novel grouped 𝑙1/2 sparsity constrained logistic regression method for sensitivity assessment of electric power failure. Different from the 𝑙1 norm and k-support norm, the proposed grouped 𝑙1/2 sparsity constrained logistic regression method simultaneously imposes the inter-class information and tighter approximation to the nonconvex 𝑙0 sparsity to exploit multiple correlated attributions for prediction. Firstly, the attributes or factors for predicting the customer sensitivity of power failure are selected from customer sheets, such as customer information, electric consuming information, electrical bill, 95598 work sheet, power failure events, etc. Secondly, all these samples with attributes are clustered into several categories, and samples in the same category are assumed to be sharing similar properties. Then, 𝑙1/2 norm constrained logistic regression model is built to predict the customer's sensitivity of power failure. Alternating direction of multipliers (ADMM) algorithm is finally employed to solve the problem by splitting it into several sub-problems effectively. Experimental results on power electrical dataset with about one million customer data from a province validate that the proposed method has a good prediction accuracy.

  • Purpose of the research: This study aims to explain the state of marketing using fun among recent popular marketing strategies. Although companies are using various differentiated marketing strategies to gain a competitive edge, among them, fun marketing has constituted the most effective area of interest recently. Research design and methodology: To extract the customer selection attributes of fun marketing, after reviewing the literature, six optional attributes were selected from the factors of fun marketing towards consumers such as funny design, language play, celebrity use, funny taste, how to eat, and newtro (new + retro). Out of 300 questionnaires, 276 were used for analysis, excluding unscrupulous or incomplete questionnaires. The results were reviewed for validity and reliability using SPSS andAMOS, and the hypothesis was verified using structural equation modelling (SEM). Principal results: The results showed that funny design, language play, and newtro statistically significantly affected customer satisfaction, but celebrity use, funny taste, and eating methods had no significant effect. It was also confirmed that satisfaction had a statistically significant effect on repurchase intention. Major conclusions: This study can serve as basic data to enhance the marketing strategy of the food service industry, and it provides theoretical and practical implications.

  • The "sharing economy" describes a type of business built on the sharing of resources - allowing customers to access goods when needed. While sharing goods has always been a common practice among friends, family, and neighbors, in recent years, the concept of sharing has moved from a community practice into a profitable business model. This study explores gaps between customers' actual usages and current policies on accommodation sharing by analyzing what needs to be done for the better establishment of sharing economy in society. The purpose of this study is to investigate perceptions of accommodation sharing by analyzing reviews and negative aspects that help resolve complaints and improve better services through policy establishment. This study investigates key attributes that influence business performance to improve citizens' decision-making for the usage of accommodation sharing. This study applies qualitative research by collecting demand- and supply-side reviews from selected registered accommodations using a random sampling procedure. This study finds that guests prefer entire house sharing with instrumental attributes related to properties. Entire house sharing of multiple dwellings shows business impacts in terms of high occupancy rate on the platform, while there are policy concerns with entire house sharing. The results provide policy and managerial implications by suggesting proper policies and considering relationships with citizens.

  • Breast cancer incidence continues to increase, and survival rates are also increasing compared to the past. An increase in breast cancer survivors means an increase in the number of women who return to their life after treatment. These patients feared cancer recurrence, which makes it an important aspect to be studied among breast cancer survivors. Therefore, this study was aimed at analyzing the concept of breast cancer survivors' fear of recurrence. The procedure of concept analysis developed by Walker and Avant (2011) was used to clarify and describe the concept. Studies published from 2007 to 2017 were searched through domestic and foreign electronic databases. Finally, 15 studies were selected and included in analysis. Through concept analysis, the scope of use of the fear of recurrence among breast cancer survivors was confirmed, and concept analysis was performed to confirm the antecedent, consequences, attributes and empirical criteria. Based on the analysis, the attributes of the fear of recurrence among breast cancer survivors included 1) worry about health status, 2) ineffective coping, and 3) possibility of changes. The antecedents of the fear of recurrence among breast cancer survivors were 1) healthcare-related activity, 2) perception of cancer, and 3) perceived severity; the consequences were 1) increase in distress, 2) difficulty in role function, and 3) decrease in the quality of life. This study provides a clear definition of the fear of recurrence among breast cancer survivors, and the results can be applied to improve the understanding of breast cancer survivors who have finished treatment and to help them return to daily life.

  • Network convergence is considered as one of the key solutions to the problem of achieving future high-capacity and reliable communications. This approach overcomes the limitations of separate wireless technologies. Efficient interface selection is one of the most important issues in convergence networks. This paper solves the problem faced by users of selecting the most appropriate interface in the heterogeneous radio-access network (RAN) environment. Our proposed scheme combines a hierarchical evaluation of networks and game theory to solve the network-selection problem. Instead, of considering a fixed weight system while ranking the networks, the proposed scheme considers the service requirements, as well as static and dynamic network attributes. The best network is selected for a particular service request. To establish a hierarchy among the network-evaluation criteria for service requests, an analytical hierarchy process (AHP) is used. To determine the optimum network selection, the network hierarchy is combined with game theory. AHP attains the network hierarchy. The weights of different access networks for a service are calculated. It is performed by combining AHP scores considering user's experienced static network attributes and dynamic radio parameters. This paper provides a strategic game. In this game, the network scores of service requests for various RANs and the user's willingness to pay for these services are used to model a network-versus-user game. The Nash equilibria signify those access networks that are chosen by individual user and result maximum payoff. The examples for the interface selection illustrate the effectiveness of the proposed scheme.

  • 모바일 인터넷은 단말기의 휴대가 가능하고 무선으로 인터넷에 접속할 수 있기 때문에 언제 어디서나 사용할 수 있다. 따라서 고정된 환경에서 사용하게 되는 유선 인터넷에 비해 모바일 인터넷 사용자는 다양한 정황 속에서 인터넷을 사용하게 된다. 본 연구에서는 이러한 여러 가지 정황 요인 들 중에서 손과 다리 및 눈에 관한 신체 정황을 선택하여, 이들이 모바일 인터넷 사용 성과와 만족도에 미치는 영향에 관하여 연구하였다. 본 연구를 위해 각 정황에서 과제를 수행하는 통제된 실험을 실시했고, 과업의 정확도와 주관적인 만족도를 측정했다 연구 결과, 각각의 정황이 개별적으로 피험자들에게 주어졌을 때는 정확도와 만족도에 영향을 미치지 않았지만. 두 개 이상의 정황이 동시에 주어졌을 때, 즉 눈에 있어서 시각적인 방해와 다리에 있어서 보행이라는 정황이 동시에 주어졌을 때 정화도 및 만족도가 떨어졌다. 이것은 주의의 한계로 인해 피험자로 하여금 하나의 신체적 정황에 대한 주의 보다 둘 이상의 신체적 정황에 대한 주의가 더 필요하게 되었고 그 결과 과업을 수행하는 인지적 주의의 양이 줄어들었기 때문임을 시사하고 있다.
