Pengaruh Promosi, Harga Dan Pelayanan Terhadap Keputusan Pembelian Toyota Dyna Dengan Jenis USAha Sebagai Variabel Moderasi (Studi Kasus Konsumen PT. New Ratna Motor, Semarang)

Goal of companies is become the market leader of their products. To achieve it, companies have to increase their sales volume. As Toyota brand holder in Central Java and DIY, PT. New Ratna Motor always tries to lead the market share in all car types, including two-tonnage vehicles (truck) class. Toyota Dyna becomes the favorite of Toyota in this class, which the competition in this class is tighter. Promotion, price, and service are some of important factors which can be related with consumer's purchase decision of Toyota Dyna and the other brands. This research is aimed to analyze is there any relation between promotion, price, and service to purchase decision of Toyota Dyna. It is continued by analysis of relationship between these three independent variables to purchase decision with business type as moderating variable. This is a quantitative research with 78 respondents as samples of Toyota Dyna users in Central Java and DIY. Questionnaires, interviews, and website are used in collecting data. Determination coefficient and Moderated Regression Analysis are used to analyze data. Result of this research is there are significant relations between promotion, price, and service to purchase decision of Toyota Dyna. Business type variable is not a moderating variable in these relationships. Advice for the company to increase sales in Toyota Dyna is develop better strategies in promotion, price, and service

Feasibility and systems definition study for Microwave Multi-Application Payload (MMAP)

Work completed on three Shuttle/Spacelab experiments is examined: the Adaptive Multibeam Phased Array Antenna (AMPA) Experiment, Electromagnetic Environment Experiment (EEE) and Millimeter Wave Communications Experiment (MWCE). Results included the definition of operating modes, sequence of operation, radii of operation about several ground stations, signal format, foot prints of typical orbits and preliminary definition of ground and user terminals. Conceptual hardware designs, Spacelab interfaces, data handling methods, experiment testing and verification studies were included. The MWCE-MOD I was defined conceptually for a steerable high gain antenna

Double negative alpha beta T cells in pediatric hemophagocytic syndromes

Introduction: Autoimmune lymphoproliferative syndrome (ALPS) and hemophagocytic lymphohistiocytosis (HLH) share clinical and laboratory features including lymphadenopathy, splenomegaly, and pancytopenia. We sought to measure αβ double negative T cells (αβ DNT) in a group of patients with established diagnosis of HLH in relation to disease activity and severity.Methods: We conducted a follow-up, controlled study that comprised 25 patients with HLH and 25 healthy matched controls. Patients were subjected to clinical evaluation and flowcytometric measurement of αβ DNT Cells at presentation and 9 weeks after start of HLH induction treatment.Results: In 17 (68%) patients, infection was the trigger of HLH while the cause was malignancy in three (12%), and rheumatological disorders in two patients (8%). At enrollment, 15 patients (60%) had αβ DNT cells levels [median (IQR): 1.71 (1.25-2.12)] that were significantly higher than the control values [median (IQR): 0.7 (0.4-0.8)] (p<0.001). The αβ DNT counts of patients were also higher at enrollment as compared to values at the end of week 9 [median (IQR): 0.76 (0.45-1.17)]; p=0.018. Survivors (n=8) and non-survivors (n=17) had comparable levels of αβ DNT cells at enrollment (p=0.861). αβ DNT cell count correlated positively with ALT (p=0.019) and negatively with CD4/CD8 ratios (p=0.023).Conclusion: Elevated αβ DNT cell counts might be related to the HLH process and this implies that mild elevation can exist in HLH and are not specific to ALPS. Wider scale studies with longer periods of follow up are needed to validate the results and properly outline the correlation between both medical conditions.Keywords: Hemophagocytic lymphohistiocytosis, Double negative T cells, mortality, ALP

Modeling Target Disinfection By-Product Dynamics in Indoor Swimming Pools

Chlorination is the primary disinfection method for swimming pools in the United States; however, chlorine also reacts with pollutants (e.g., sweat, urine and anthropogenic compounds) to form disinfection by-products (DBPs). Some DBPs are asthma causing (e.g. nitrogen-trichloride) and even carcinogens (e.g., trihalomethanes and nitrosamines). Consequently, exposure to DBPs poses health risks to patrons and staff in pool environments. Furthermore, volatilization of DBPs is enhanced by bather activity, but the relationship between activity and volatilization has yet been quantified such that the dynamic behavior of DBPs can be predicted. Therefore, the objective of this research is to clarify the relationship between bather activities and the behavior of DBPs quantitatively in order to simulate the liquid-phase transportation of target DBPs in indoor pools. An acoustic Doppler velocimeter will monitor the velocity of water over a period of time at various depths below the water surface to measure turbulence, which corresponds to bather activity. Concentration measurements of target DBPs will be taken parallel to the time and depth of the velocity readings, and then correlated to determine the turbulent diffusion coefficients of the target DBPs. The collected data will be used to construct a DBP transport model which predicts the concentration of target DBPs over time under inputted conditions. The result will give a quantitative relationship between physical activities of swimmers and transportation of target DBPs in indoor swimming pools
