ISLAND TOURISM EXPERIENCES

Cristina Oliveira,S?rgio Moro,Ana Brochado 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

In consumer perception, sensory marketing plays a key role in promoting hedonic consumption and influencing customer experience. This relationship should be even more emphasized in services such as tourism. Due to its diversity, Cape Verde, a small island developing state (SIDS) according to OECD, has recently been promoted by its national tourist office as an archipelago of the islands of the senses. As such, this study aims to identify the main dimensions of tourist experience in one of the islands, Santo Ant?o, based on user generated content (UGC). Social media, namely online travel reviews, have been reported not only to influence consumer decision making but also to exert the strongest impact on behavior intention (Aye, Au & Law, 2013). Moreover, online reviews have been increasingly used in tourism services as well as considered by tourists as most useful and trustworthy (Au, Buhalis & Law, 2014). Taking into account the recognized limitations of traditional research methods, such as surveys, and the opportunities given by Web 2.0 sites, this research collected data of online reviews on that island of the senses from TripAdvisor, totaling 111 web reviews from its 10 most important tourist attractions. Data was subjected to content analysis by using Leximancer software in order to extract and organize information on words, concepts and themes stemming from visitor narratives. This lead to the generation of a concept map showing thirteen as the most common themes by their level of importance. The most frequently mentioned ones were crater and view, followed by hike. Place, landscape, island and sea came next. These were then followed by clouds, people, guide, taxi, mountain and water. This study analyses these findings bringing academic literature to the discussion. The current study was performed to add value to existing scientific research by fostering a deeper understanding of tourist experience in island destinations and focusing on an under researched country like Cape Verde. Management from national tourism organizations will likely benefit from this research since by implementing our text mining procedure to online reviews they can significantly improve their monitoring capabilities and be responsive to tourist feedback. These study´s limitations trigger the need to extend this research to other Cape Verde islands with the goal of identifying additional dimensions characterizing the diversity of this archipelago. This will also be matched with a thorough analysis of demographic and psychographic characteristics of the reviewers.

This study investigated the effect of Ganoderma lucidum supplementation on lymphocytes and peritoneal macrophages from mice. Our results show that G. lucidum in vivo was able to increase interferon-γ (IFN-γ) concentration but reduced CD3+ and CD8+ spleen lymphocytes. Ex vivo, IFN-γ; and interleukin-10 levels were increased and the tumor necrosis factor-α (TNF-α) level was reduced by peritoneal macrophages from mice fed with G. lucidum. In the absence of stimuli nitric oxide production was reduced in mice fed with G. lucidum, and with lipopolysaccharide stimulation nitric oxide production was increased but was lower than control values (P<.05). G. lucidum was grown by solid-state culture in wheat grain, and a chow containing 10% G. lucidum mycelium was formulated (G10). Swiss male mice were divided into two groups, termed G10 and control groups according to the diet, and were fed for 3 months. Peritoneal macrophages were obtained and investigated with regard to phagocytosis, lysosomal volume, hydrogen peroxide, superoxide anion, and cytokines ex vivo. In the plasma we investigated concentrations of cytokines, and in the spleen we determined subsets of CD3+, CD4+, CD8+, and CD19+ lymphocytes.

Gustavo Maluf,Rogé,rio Jardim Caldas,Eduardo Rodrigues Fregnani,Paulo Sé,rgio da Silva Santos 대한구강악안면외과학회 2020 대한구강악안면외과학회지 Vol.46 No.2

We present a case of osteoradionecrosis treated with leukocyte- and platelet-rich fibrin (LPRF) and surgery and followed up with clinical and tomographic investigations. A 65-year-old woman presented with pain in the posterior region of the right palate. Her medical history included cardiovascular disease and squamous cell carcinoma in the anterior region of the floor of the mouth that had been treated with intensity-modulated radiation therapy. Measurements of isodose curves showed a full dosage of 6,462.6 cGy in the anterior mandibular region, whereas that in the posterior region on the right side of the maxilla reached 5,708.1 cGy. Osteotomy was performed using rotary instruments, and debridement and placement of two LPRF membranes were also carried out. New gum tissue with no bone exposure was noted 14 days postoperatively. Tissue repair was complete, and the patient had no further complaints. During a 39-month follow-up period, the oral mucosa remained intact, and the patient was rehabilitated with a new upper denture. Since there is no consensus regarding the best protocol to treat osteoradionecrosis, LPRF might be an interesting adjuvant to a surgical approach. The use of LPRF is simple and reduces operational costs, time of handling, probability of technical failure, and associated morbidities for patients with osteoradionecrosis.

The prevalence of gastrointestinal disorders, such as constipation, has been increasing. Genetic factors and lifestyle are some of the etiologies of this issue, affecting the health of the population. Natural products have properties that contribute to health maintenance and health promotion, including reduction of the inflammatory process. Hancornia speciosa, popularly known as mangaba, is an abundant and native fruit in the Brazilian Cerrado, commercialized for culinary purposes and used because of its pharmacological properties. The objective of this study was to evaluate if the supplementation of different concentrations of mangaba pulp can improve intestinal motility and bowel health in Wistar rats. Forty male rats were divided into five groups. The experiment lasted 14 days and the groups were tested with water, industrialized laxative jelly made from tamarind as medication, or mangaba at 5, 10, and 15 mL/kg of body weight. Food intake, weight gain, ion balance, intestinal motility, and histopathological analysis of the small intestine, large intestine, and liver were evaluated. Supplementation of mangaba pulp at its highest concentration (15 mL/kg body weight) caused a 15% increase in the distance traveled by the charcoal meal, and a decrease in serum magnesium levels and white cells in both the small and large intestines. The results suggest that mangaba pulp presents laxative, anti-inflammatory properties and that its consumption is beneficial and should be encouraged.

Alexandre Simõ,es Garcia,Otá,vio Pagin,Paulo Sé,rgio da Silva Santos,Denise Tostes Oliveira 대한구강악안면외과학회 2016 대한구강악안면외과학회지 Vol.42 No.6

Oral verruciform xanthoma (OVX) is an uncommon lesion that appears on the oral mucosa. The aim of this paper was to discuss the probable etiopathogenesis of OVX in the hard palate, reinforcing the importance of including this lesion in the differential diagnosis of verrucous lesions. A 43-yearold male smoker presented with a painless lesion with a verrucous surface and erythematous spots on the hard palate. Excisional biopsy revealed oral mucosa consisting of hyperkeratosis, acanthosis, and elongated rete pegs. Subjacent connective tissue showed numerous foam cells with clear cytoplasm and pyknotic nucleus, negative on periodic acid-Schiff staining. Immunohistochemical analysis revealed foam cells positive for anti-CD68 antibody, while anti-KI-67 antibody was restricted to the basal layer of the oral epithelium. A final diagnosis of OVX was established. The patient showed no signs of recurrence after seven months of follow-up. Physical trauma and smoking habits can be directly related to the etiology of verruciform xanthoma because the lesion is chronic and inflammatory with slow growth, and sites if high trauma are more often affected by such a lesion. The hard palate is the second most commonly affected site, and local trauma caused by smoking can be a cause of this type of lesion.

Yacon flour has been considered a food with prebiotic potential because of the high levels of fructooligosaccharides, which allows for its use in formulating synbiotic foods. The purpose of this study was to evaluate the effect of yacon flour and probiotic (Bifidobacterium longum) on the modulation of variables related to bone health. Thirty-two Wistar rats were divided into 4 groups: control, yacon flour, diet + B. longum, and yacon flour + B. longum. After euthanasia, the bones were removed for analysis of biomechanical properties (thickness, length, and strength of fracture) and mineral content (Ca, Mg, and P); the cecum was removed for analysis of the microbiota and short-chain fatty acids. Tibia Ca, P, and Mg content was significantly (P < .05) higher in groups fed diet + B. longum, yacon flour + B. longum than in the control group. An increase in fracture strength was observed in the yacon flour (8.1%), diet + B. longum (8.6%), and yacon flour + B. longum (14.6%) in comparison to the control group. Total anaerobe and weight of the cecum were higher (P < .05) in rats consuming the yacon flour diet compared with the other groups. Cecal concentration of propionate was higher in all experimental groups compared with the control (P < .05). Yacon flour in combination with B. longum helped increase the concentration of minerals in bones, an important factor in the prevention of diseases such as osteoporosis.

Cheese ripening involves lactose metabolism, lipolysis and proteolysis, which are affected by many factors. The aim of this study was to assess changes due to ripening (90 days) of goat milk cheese through bacteriological and physicochemical analysis in order to verify if, at the end of ripening period, this cheese could be considered ‘‘lactose-free’’. Three batches of the goat milk cheese were manufactured and ripened at 10 C and 80% relative humidity for 90 days. Titratable acidity increased by about 59 D due to carbohydrate degradation and organic acid production. However, pH (5.31–5.25) remained constant. Lactococcus was the dominant cheese microbiota, acting in the fermentation of lactose (1.17–0.06 mg/g) and lactic acid production (5.49– s10.01 mg/g). Thus, ripening time was decisive for bacteriological and physicochemical goat milk cheese characteristics.

Brena Rodrigues Manzano,Natá,lia Garcia Santaella,Marco Auré,lio Oliveira,Cá,ssia Maria Fischer Rubira,Paulo Sé,rgio da Silva Santos 대한구강악안면외과학회 2019 대한구강악안면외과학회지 Vol.45 No.1

Objectives: Osteoradionecrosis (ORN) is one of the most severe complications resulting from radiotherapy (RT) in patients with head and neck cancer (HNC). It is characterized by persistent exposed and devitalized bone without proper healing for greater than 6 months after a high dose of radiation in the area. To describe the profile and dental management of ORN in HNC patients undergoing RT in an oncological clinical research center. Materials and Methods: A retrospective descriptive study was performed to analyze dental records from HNC patients with ORN treated at an oncological clinical research center from 2013 to 2017. A total of 158 dental records for HNC patients were selected from a total of 583 records. Afterwards, this number was distributed to three examiners for manual assessments. Each examiner was responsible for selecting dental records that contained an ORN description, resulting in 20 dental records. Results: Mean patient age was 60.3 years with males being the most affected sex (80.0%). The most affected area was the posterior region of the mandible (60.0%) followed by the anterior region of the mandible (20.0%) and the posterior region of the maxilla (10.0%). The factors most associated with ORN were dental conditions (70.0%) followed by isolated systemic factors (10.0%) and tumor resection (5.0%). There was total exposed bone closure in 50.0% of cases. The predominant treatment was curettage associated with chlorhexidine 0.12% irrigation (36.0%). Conclusion: Poor dental conditions were related to ORN occurrence. ORN management through less invasive therapies was effective for the closure of exposed bone areas and avoidance of infection.

Study of Optical Transmission Performance in IP-over-WDM Networks Based on FSK/ASK Combined Modulation Format

Xin Xiangjun,António Luís Jesus Teixeira,Paulo P. Monteiro,José R. F. da Rocha,Paulo Sérgio de Brito André 한국전자통신연구원 2005 ETRI Journal Vol.27 No.3

The transmission performance of optical labeling based on a combined frequency shift keying/amplitude shift keying (FSK/ASK) format is studied by numerical simulation. The simulation demonstrates that the bit-error ratio (BER) characteristic of an ASK signal is limited by the extinction ratio, received optical power, and dispersion, simultaneously. However, an FSK signal is mainly limited by the extinction ratio (ER) and received optical power when the peak spectrum, which is used to detect the FSK signal, is relatively narrow.
