In the era of social media, marketers have struggled to understand and serve participants' diverse and multifaceted needs in a novel form of online brand community in the social-networking sites such as Facebook. Thus, this study identifies different groups of participants affiliated with Facebook brand pages based on their needs for brand connection. The need-based segments are validated by comparing results across foodservice and consumer goods. Results of cluster analysis reveal three distinct segments (i.e., residents, lurkers, and peepers) based on participants' functional, experiential, and incentive needs. Results of multivariate analysis of variance illustrate significant differences in relational tendencies for a brand of interest among these three groups. The three groups are profiled based on participants' engagement level. Findings of this study are expected to help marketers better understand the needs of diverse participants in their SNS-embedded brand community so they can develop tailored communication strategies for targeted groups.

Interface effects on properties of NTC thermistors having Mn-Co-O spinel crystal structure system are analyzed by a mixing rule in case of mixed types and layered types between CuO and Al$_2$O$_3$ added compounds. With adding CuO and Al$_2$O$_3$, The compounds form completely solid solution and their resistance and B constant are changed due to the variation of conduction electrons by their ionic substitutions. The properties of mixed NTC thermistors are depended on the logarithmic mixing rule by a dispersed phase and they show slightly lower values due to the lattice mixing affect in compared with calculated values. The resistance of layered NTC thermistors is depended upon the series mixing rule containing the value of an interface layer and effected by the variation of its thickness, and it is changed rapidly to the logarithmic mixing rule by the connection between two layers with increasing the interface layer

As a non-linear time variant system, the four-quadrant line converter of an electric multiple unit (EMU) was expressed by linear time periodic functions near an operating point and modeled by a steady-state harmonic domain matrix. The components were then combined according to the circuit connection and relations of the feedback control loops to form a complete converter model. The proposed modeling method allows the study of the amplitude of harmonic impedances to explore harmonic coupling. Moreover, the proposed method helps provide a better design for the converter controllers, as well as solves the problem in coordination operation between the EMUs and the AC supply. On-site data from an actual $CRH_2$ high-speed train were used to validate the modeling principles presented in the paper.

Recently, the mRFID which combines RFID system a mobile uses infra of mobile communication and it provides object information service with the form which is various. Currently, many object information service system exists. But such system object information is by a service box and becomes the inclusion in specific territory and connection it does from different territory, there is a difficult problem point. It secured the weak point of object information service system of existing from the dissertation which it sees and the object information service system which is suitable in application development of the mRFID it embodied.

A 65-year-old woman presented with a solid mass on the right temporal area. The mass had grown for over 2 years without any initiating event of trauma or inflammation. Before excision, the patient went through a computed tomography scan, revealing a calcified mass without bony connection. Under general anesthesia, an excisional biopsy was performed. Microscopic examination confirmed a diagnosis of soft tissue osteoma. Soft tissue osteoma is rare, especially in the head and neck region. Osteomas in the temporal region have not been reported yet. Due to its rarity, osteoma might be misdiagnosed as another soft tissue or bone origin tumor. Its treatment of choice is simple excision. In this review, we present an unusual clinical form of soft tissue osteoma.

Recently, the Univeral Plug and Play (UPnP) Form has relased UPnP Cloud, which is an extension to the basic UPnP architecture that enables device to device connectivity across the Internet. UPnP Cloud uses the Extensible Messaging and Presence Protocol (XMPP) to connect devices located in different domains. In this paper, the details of the UPnP Cloud are presented. We demonstrate how UPnP Cloud enables contents to be shared remotely, and how it can be used in connection with DLNA.

Constant stress partially accelerated life tests are studied according to exponentiated Weibull distribution. Grounded on multiple censoring, the maximum likelihood estimators are determined in connection with unknown distribution parameters and accelerated factor. The confidence intervals of the unknown parameters and acceleration factor are constructed for large sample size. However, it is not possible to obtain the Bayes estimates in plain form, so we apply a Markov chain Monte Carlo method to deal with this issue, which permits us to create a credible interval of the associated parameters. Finally, based on constant stress partially accelerated life tests scheme with exponentiated Weibull distribution under multiple censoring, the illustrative example and the simulation results are used to investigate the maximum likelihood, and Bayesian estimates of the unknown parameters.

The hospital biomedical engineering team is responsible for establishing and regulating the Medical Device Management Program (MEMP) to ensure that medical devices are safe and reliable. As technology advances, medical devices such as artificial intelligence and precision medicine are developing into a form that allows connection between objects anytime, anywhere, and as various technologies converge, internal and external security threats continue to increase. In this paper, we present a study of the Medical Device Management Program (Secure-MEMP) method, considering that the security threat of medical devices continues to increase due to advances in technology.

"Behind a Mask" (1866) marks the new direction of Louisa May Alcott's artistic and personal life. Her European trip solidified her identity as a mature woman, most importantly as a mature American woman, one whose independence from Victorian stereotypes would, from now on, make her fortune and fame. Her sensational stories, especially "Behind a Mask," would tell truths that readers recognized but had rarely seen written. These truths would free them, and the author herself, to explore their talents as individuals. Henceforth, Alcott would embody the successful American artistic entrepreneur as one who shed the European domination of false titles and inherited wealth. These motifs of the transnational connection pervade the story, in the form of images and likenesses. Just as Alcott would soon, in two years, reach astonishing financial success with the publication of Little Women, her meteoric ascent parallels America's rise to power in the world's economy, which came about with almost alarming speed after the conclusion of the American Civil War.

The article is devoted to current problems of the concept leadership. The essence of the concept of "leadership" is considered and leadership theories. The authors of the article conducted a multifaceted analysis of leadership theories, analyzed the factors of their formation and identified their relationship. Also, the reasons for the difference and connection between leadership and leadership. Styles were presented leadership and their role in building effective leadership. To form the basis of effective leadership was compared to the main criteria inherent in this theories. The following research methods were used in the work: theoretical (analysis of regulatory documents and scientific literature on the problem under study, comparison, generalization, modeling), empirical (diagnostics of the level of formation of managerial competencies of students of the system, questioning, observation, peer review, comparative qualitative and quantitative analysis of diagnostic results the level of formation of managerial competencies).
