Atma Jaya Catholic University of Indonesia is an institute of higher learning in Jakarta, Indonesia, which was founded by Atma Jaya Foundation on June 1, 1960. The main campus is located at Semanggi area, South Jakarta and the other campus is located in Pluit, North Jakarta.According to a survey by GlobeAsia Magazine in 2008 Atma Jaya was ranked third among all private universities in Indonesia. While the survey of Tempo magazine from 2005 to 2007 put Atma Jaya in the top ten best universities in Indonesia. The General Directorate of Higher Education categorizes Atma Jaya in 50 Promising Indonesian Universities out of 2864 higher education institutions in Indonesia.Since 2008 Atma Jaya has been increasing the number of undergraduate and graduate programs, and is constructing a new campus in Bumi Serpong Damai, Tangerang.

This study is aimed to test the manager's satisfaction of the managers using the ERP and to test the influence of job satisfaction towards the performance in the decision process by the manager. The measurement of the satisfaction towards the ERP system will be conducted using the end user's satisfaction computing model (EUCS), using the content, accuracy, formal ease of use, and timelines attributes (Doll and Torkzadeh, 1988). Whereas, the performance is measured using the instrument which was developed by Nicolaou (2000) consisting of 2 (two) question items about the reporting and continuing control, 7 (seven) items of questions adopted from the study results of Spathis and Constantinides (2004). The data were collected through a survey using questionnaires distributed to companies that have used the ERP system. The data analysis used the Partial Least Square method with SmartPLS program. The results show that the concept of EUCS has a conformation and there is a significant effect between the ERP system user satisfaction with the manager's performance, especially in the decision making process. This result contributes to the concept of EUCS and supports previous research related to end user satisfaction. Source

In a highly competitive service environment, service providers have to provide customers with delightful service experience in order to attract more customers and achieve higher customer satisfaction. Managing service experience is a critical approach for service providers to consider. Although customer experience management (CEM) has been discussed across different research disciplines, there is still no systematical and feasible way to apply CEM into real environments. This study attempts to examine the customer experience by using cluster analysis, cross tabulation test, importance-satisfaction (IS) model, and house of quality (HOQ) method for CEM. We illustrate the process using an empirical case study at a well-known café in Jakarta, Indonesia. This mechanism can help service providers design and deliver delightful service experience to customers. Source

The development of electronics industry in keeping the chip size to be smaller has challenged its thermal management to maintain the maximum chip temperature below 80 °C. The correlation as a method to estimate chip temperature, when only the chip's heat rate or power input and inlet coolant temperature are known, is obtained. The equations involving pressure drop, pool boiling and film condensation characteristics that explain the heat transfer process and flow phenomenon inside the thermosyphon flow are derived to obtain the correlation. A new design of a two-phase thermosyphon water-cooled condenser system as the electronic cooling system has been built to acquire the experimental data. This thermosyphon design uses R-113 as working fluid and water as external coolant condenser (flows through the cooling coil). The condensation occurs as film condensation at the outer of radial water coolant coil. The R-113 liquid condensate will then return back to the evaporator section through the downcomer section by gravity rather than by capillary forces. The thermosyphon system (excluding the water coolant coil section) is thus a passive system, and its evaporator section must be located below the condenser. In the present work, the heat supply component is simulated by a cartridge heater. This cartridge heater is in direct contact with the working fluid. The water coolant condenser is supplied by solution bath. Furthermore, the evaporator, riser, condenser, and downcomer are well insulated and all applied heat is assumed to be transferred through the thermosyphon. In the experiment, the varying mass flow rate and voltage at a constant inlet water temperature ( ) of 10°C, 15°C and 20°C were measured. The correlation obtained as function of heat flux and temperature difference between chip and coolant inlet temperature is valid as they are in good agreement with the experimental results. © 2006-2016 Asian Research Publishing Network (ARPN).

In periodontal disease, gingival fibroblasts activated by the Gram-negative anaerobic bacterium Porphyromonas gingivalis induce overexpression of matrix metalloproteinase-2 (MMP-2), which is involved in inflammatory progression. This process is followed by tissue destruction and bone loss. In the present study, we investigated the in vitro effect of the ethanolic Kaempferia pandurata Roxb. extract on expression of MMP-2 in P. gingivalis-treated human gingival fibroblast-1 (HGF-1) cells. In addition, we utilized gelatin zymography, Western blotting, and reverse transcription-PCR analysis to elucidate the molecular mechanisms underlying MMP-2 inhibition via the mitogen-activated protein kinase (MAPK) and cyclic AMP response element-binding protein (CREB) signaling pathways. Treatment with K. pandurata extract (1-10 μg/ml) dose-dependently suppressed the activity, secretion, and protein expression of MMP-2 in HGF-1 cells exposed to P. gingivalis. At the transcriptional level, inhibition of MMP-2 gene expression by K. pandurata was mediated by phosphorylation of c-Jun N-terminal kinase (JNK) and CREB signaling pathways in P. gingivalis-treated HGF-1 cells. These results suggest that K. pandurata extract suppresses MMP-2 expression at the protein and gene levels via downregulation of the principal JNK and CREB signaling pathways. Due to its efficacy in inhibiting MMP-mediated periodontal destruction, K. pandurata might represent a new, potent periodontal therapy. Source

Punctured convolutional codes are known to have low complexity compared to their nonpunctured counterpart, while retaining a good performance. Analyzing the performance of punctured convolutional code can be simplified by using non-punctured equivalent code. In this paper new punctured convolutional codes with rates of 3/8, 3/7 and 3/6 are proposed, and their performances are studied by first constructing non-punctured equivalent codes. Simulations results show that different puncturing patterns will affect the code performances. Further investigations show that puncturing adjacent bits is to be avoided as it tends to degrade the code performance, as indicated by a decrease of the free distance by 9% and 33% below average for code rates 3/7 and 3/6 respectively. On the contrary, dispersed punctured bits will yield good code performance as indicated in the increase of the free distance by 27% and 32.45% above average for code rates 3/7 and 3/6 respectively.
