This study aimed to identify the effects of fashion brand extensions types, preannouncing and consumers' regulatory focus on preference towards extension products. To that end, the study used a 2 (fashion brand extension types: similar vs. non-similar) ${\times}2$ (preannouncing: near preannouncing vs. far preannouncing) ${\times}2$ (regulatory focus: promotion focus vs. prevention focus) three mixed elements. The subjects of the study were 280 men and women in their 20~40s living in Seoul and Chungnam province and total of 229 data were analyzed. Data were analysed with SPSS 19.0 program and three-way ANOVA, simple interaction effects and simple main effects analysis were conducted. The results of this study are as follows: First there were significant differences in preference based on fashion brand extension types and preannouncing. Second, there were significant interaction effects in preference between extension types of fashion brand and regulatory focus. But there was no difference in preference toward extension products according to types of preannouncing and regulatory focus. Lastly, fashion brand extension types, preannouncing and regulatory focus showed significant interaction effects on preference. Thus even in cases of non-similar brand extensions which carry more risk of failing, the appropriate marketing communication strategies such as preannouncing will result in brand preference. Also marketing activities should be comprehensive and strategical based on consumers' tendencies in order to derive positive evaluations.

Brucellosis, a bacterial zoonoses caused by the genus Brucella is responsible for abortion and infertility in cow. Brucellosis is causing economic loss in dairy industries and prevalent worldwide including Bangladesh but limited studies are devoted to determine the prevalence and its association with reproductive factors of dairy cows in Bangladesh. Therefore, the present study was conducted to determine the seroprevalence of brucellosis in dairy cattle using screening test Rose Bengal test (RBT) and the positive sera were further confirmed by indirect- ELISA. For this purpose, a total of 400 serum samples from dairy cows with history of abortion and various reproductive disorders were collected from the Kurigram district of Bangladesh for the detection of Brucella antibody. The overall prevalence of brucellosis in dairy cattle was 2.25%. Brucellosis in cases of abortion and repeat breeding was 8.3% and 2.8%, respectively. The results shows higher prevalence of brucellosis in cases of abortion followed by repeat breeding, while there was no seropositive cases from other reproductive disorders. Age-wise sero-prevalence was found 3.0% in 2~3 years age group and 2.0% in 4~8 years age group. The prevalence of brucellosis in indigenous and cross-bred cattle was 3.6% and 1.7%, respectively. All the animals detected positive to brucellosis by RBT were not found to be positive by i-ELISA. However, the RBT might be a suitable screening test for the diagnosis of Brucella infection in field condition in Bangladesh. These data will help to develop effective disease prevention strategies.

We stand at the brink of a fundamental change in how medicine will be practiced. Over the next 5-20 years medicine will move from being largely reactive to being predictive, personalized, preventive and participatory (P4). Technology and new scientific strategies have always been the drivers of revolutions and this is certainly the case for P4 medicine, where a systems approach to disease, new and emerging technologies and powerful computational tools will open new windows for the investigation of disease. Systems approaches are driving the emergence of fascinating new technologies that will permit billions of measurements on each individual patient. The challenge for health information technology will be how to reduce this enormous amount of data to simple hypotheses about health and disease. We predict that emerging technologies, together with the systems approaches to diagnosis, therapy and prevention will lead to a down turn in the escalating costs of healthcare. In time we will be able to export P4 medicine to the developing world and it will become the foundation of global medicine. The "democratization" of healthcare will come from P4 medicine. Its first real emergence will require the unprecedented integration of biology, medicine, technology and computation. as well as societal issues of major importance: ethical, regulatory, public policy, economic, and others. In order to effectively move the P4 scientific agenda forward new strategic partnerships are now being created with the large-scale integration of complementary skills, technologies, computational tools, patient records and samples and analysis of societal issues. It is evident that the business plans of every sector of the healthcare industry will need to be entirely transformed over the next 10 years.and the extent to which this will be done by existing companies as opposed to newly created companies is a fascinating question.

Background: Multiple myeloma (MM) is characterized by a neoplastic proliferation of plasma cells primarily in the bone marrow. Bisphosphonates (BP) are used as supportive therapy in the management of MM. This study aimed to analyze the incidence, risk factors, and clinical outcomes of medication-related necrosis of the jaw (MRONJ) in MM patients. Methods: One hundred thirty MM patients who had previous dental evaluations were retrospectively reviewed. Based on several findings, we applied the staging and treatment strategies on MRONJ. We analyzed gender, age, type of BP, incidence, and local etiological factors and assessed the relationship between these factors and the clinical findings at the first oral examination. Results: MRONJ was found in nine male patients (6.9%). The mean patient age was 62.2 years. The median BP administration time was 19 months. Seven patients were treated with a combination of IV zoledronate and pamidronate, and two patients received single-agent therapy. The lesions were predominantly located in the mandible (n = 8), and the most common predisposing dental factor was a history of prior extraction (n = 6). Half of the MRONJ were related to diseases found on the initial dental screen. Patients with MRONJ were treated with infection control and antibiotic therapy. When comparing between the MRONJ stage and each factor (sign, location, etiologic factor, BP type, treatment, and outcome), there were no significant differences between stages, except for between the stage and sign (with or without purulence). Conclusions: For prevention of MRONJ, we recommend routine dental examinations and treatment prior to starting BP therapy.

Background: Smartphones are a modern necessity. While they are convenient to use, smartphones also have side effects such as addiction. This study assessed the relationship between smartphone use, a part of everyday life in modern society, and oral health. Methods: An analysis was conducted using 2017 Korea Youth Risk Behavior Web-based Survey data. The propensity score estimation algorithm used logistic regression and 1:1 matching algorithm using nearest-neighbor matching. After matching, a total of 15,032 participants were classified into two groups containing 7,516 teenagers each who did and did not use smartphones, respectively. Results: Comparison of oral health behaviors according to smartphone use revealed a statistically significant difference in the frequency of tooth brushing per day, use of oral hygiene products, intake of foods harmful to oral health, and experience of oral health education (p<0.05). The factors affecting oral pain experience of adolescents were examined. Compared to male participants, female participants had an odds ratio of 1.627 for oral pain (p<0.05). According to the household income level, compared to the group with higher income, the group with lower income showed higher oral pain experience (p<0.05). Oral pain experience was 1.601 times more frequent among teenagers using smartphones (p<0.05). Conclusion: The results of this study indicated that use of smartphones by adolescents affected their oral health. These findings indicate the need for improved oral health management through the use of effective school oral health programs and individual counseling by oral health professionals, promotion of information dissemination through public media, and development of prevention strategies.
