A comprehensive understanding of the randomness, arbitrariness, and complexity of the visitors’ behavior and interaction in a museum is important because it is associated with the design. There is still uncertainty about how to characterize the visitors’ behavior and interaction. The fractal dimension was used in this study to indicate the geometrical form of the aged’s, the families’, and the students’ walking trajectories. The study results represented that all three sorts of the walking trajectory fractal-dimension-time curves fluctuated in the early stage. A remarkable exponential converges could then be observed. The mean fractal dimension after the convergence of the aged’s, the families’, and the students’ walking trajectory was nearly 1.8, 1.6, and 1.2, respectively. Furthermore, the behavior characteristics of these three sorts of visitors were quantified and the reasons were speculated and inferred. The comprehensive consideration of fractal geometry can aid in visitors’ behavior modeling and museum design.

Early Stage Design

In the early stages of a product development process (PDP), VR can facilitate communication between designers and product end-users to improve the quality of feedback that user provide to designers. While various forms of VR can already be found in the PDP, they primarily target designers, rather than designers and end-users. Furthermore, available tools and toolkits do not match the skills and requirements of designers in early stages of the PDP. The current paper presents an approach that first identifies how to effectively support early stage design activities (referred to as the application) and subsequently provides designers with tools to realize this application themselves. The approach is implemented in an industrial case study involving practitioners from a multinational manufacturer of printing solutions for professional markets. The Virtual Printshop resulting from this case study provides an evaluation platform for various types of early stage product evaluations. A concluding generalization of the cases study results shows that the application can be translated to several other design domains. Furthermore, it was found that there are similarities in how these different design domains integrate VR design tools with their existing tool chains.

Providing memorable tourism experiences (MTEs) plays a crucial role in determining the competitiveness and sustainability of a destination for not only the business sector, but also the environment. Therefore, destination managers face a challenge in identifying, facilitating, and maintaining memorable tourism experiences among visitors. Although MTEs have been increasingly studied, research of the effects of MTEs on word-of-mouth and revisit behavior intentions is still at an early stage of development, particularly in the forest recreation context. The objectives of this study were twofold: To assess visitors’ MTEs in a selected forest recreation destination and to examine the effects of MTEs on word-of-mouth and revisit intentions. This study identified key memorable experiences of visitors in Xitou Nature Education Area (XNEA), Taiwan (R.O.C.), and examined the relevant relationships among MTEs and behavioral intentions. The results revealed that both refreshment and involvement experiences received the highest scores from the respondents, whereas perceived local culture received the lowest score. Refreshment, local culture, and involvement positively influenced the word-of-mouth intention of visitors. Additionally, hedonism, local culture, and involvement significantly positively influenced the revisit intention of visitors. This study provides additional insights into MTEs in nature-based tourism. The study results underline the importance of MTEs in forest recreation destinations that can encourage more word-of-mouth and revisit intentions of tourists.

Carcinoma Mammae (CM) is a malignancy of epithelial cells restricting at the breast ducts or lobes which causes very high mortalityrate. The Neutrophil/Lymphocyte ratio (NLR) is reflecting the inflamatory status, has been reported to be a prognostic indicator in somemalignant tumors. The purpose of this study is to know the NLR as an indicator of the progressivity of CM by analyzing it. A retrospectiveobservational study performed using data from the medical record of CM patients at Wahidin Sudirohusodo Hospital from January 2010up to December 2012. The diagnosis were established by the clinicians based on the result of histopathological exsamination, chest X-ray,abdominal ultrasound, bone scan and CT scan. The patients with surgical history, chemotherapy, radiotherapy, leukocytes >12.000/mm3and incomplete data were excluded from the analysis. The data distribution was analyzed using Kolmogorov-Smirnov test. The relationbetween NLR in CM was analized by One way ANOVA test and post hoc analysis. The result were 130 samples, consisting of 17 patientsin early stage, 71 in stage III and 42 in stage IV CM. In the early stage the mean of NLR were 1.69, 2.04 in stage III and 2.89 in stage IVand their differences were statistically significant (p<0.001). Post hoc analysis showed that the significant differences occurred betweenthe early stage and IV, as well as between stage III and IV. The mean of NLR were 2.28±1.02 in the non metastatic and 3.36±1.5 in themetastatic they were statistically significant (p<0.001). Based on the study results can be concluded that the neutrophil/lymphocyteratio can be used to assess the progressivity of CM. Further studies with larger samples were needed for the determination of the cut offpoint of NLR.

Purpose The purpose of this paper is to develop a 5As framework for entrepreneurial nudge public leadership for health and wellness promotion based on two exemplary cases in Mississippi. Design/methodology/approach The authors use a “case within a case” study design to develop the 5As public influence framework for entrepreneurial public leadership. Findings Based on the investigated cases of healthcare and wellness promotion in Hernando and Charleston, Mississippi, the authors developed the 5As framework for wellness promotion dimensions of awareness, assistance, alignment, association, and assessment. This framework is applicable to the lived experiences of community members, leaders, healthcare providers, and government. Research limitations/implications The study results provide a compelling insight into early-stage formation of entrepreneurial public leadership. However, the study results lack generalizability due to the case study approach used. Practical implications This study can assist entrepreneurial public leaders and policy-makers align their strategic wellness goals, initiatives, and policies that motivate community members to seek and receive supporting services. Originality/value Developing an original framework for wellness promotion useful to both healthcare practitioners and public leaders, this study contributes to the extant literature on public health leadership and proposes mechanisms for addressing community wellness needs. The framework is designed to address public health concerns by integrating public leadership strategies aimed at linking with existing community wellness and healthcare services.

Biofuels and biochemicals play significant roles in the transition towards a fossil-free society. However, large-scale biorefineries are not yet cost-competitive with their fossil-fuel counterparts, and it is important to identify biorefinery concepts with high economic performance. For evaluating early-stage biorefinery concepts, one needs to consider not only the technical performance and process costs but also the economic performance of the full supply chain and the impacts on feedstock and product markets. This article presents and demonstrates a conceptual interdisciplinary framework that can constitute the basis for evaluations of the full supply-chain performance of biorefinery concepts. This framework considers the competition for biomass across sectors, assumes exogenous end-use product demand, and incorporates various geographical and technical constraints. The framework is demonstrated empirically through a case study of a sawmill-integrated biorefinery producing liquefied biomethane from forestry and forest industry residues. The case study results illustrate that acknowledging biomass market effects in the supply chain evaluation implies changes in both biomass prices and the allocation of biomass across sectors. The proposed framework should facilitate the identification of biorefinery concepts with a high economic performance which are robust to feedstock price changes caused by the increase in biomass demand.

Abstract Inclusion of cerium (Ce) oxide particles as an abrasive into chemical mechanical planarization (CMP) slurries has become popular for wafer fabs below the 45nm technology node due to better polishing quality and improved CMP selectivity. Transmission electron microscopy (TEM) has difficulties finding and identifying Ce-oxide residuals due to the limited region of analysis unless dedicated efforts to search for them are employed. This article presents a case study that proved the concept in which physical evidence of Ce-rich particles was directly identified by analytical TEM during a CMP tool qualification in the early stage of 20nm node technology development. This justifies the need to setup in-fab monitoring for trace amounts of CMP residuals in Si-based wafer foundries. The fact that Cr resided right above the Ce-O particle cluster, further proved that the Ce-O particles were from the wafer and not introduced during the sample preparation.
