  • The U.S. General Aviation Revitalization Act of 1994 (the "GARA") created a statute of repose that bars any claims arising from an aviation product or component more than 18 years after its date of delivery. The statute was enacted to protect general aviation aircraft manufacturers from the excessive product liability costs. The GARA included four exceptions: (a) medical emergency patients, (b) those not on the aircraft, (c) those based on written warranties, and (d) those causally related to a "knowing misrepresentation" made by the manufacturer to the FAA. The GARA also incorporates a provision for revised starting point of reckoning to which any repairs or replacements of an aviation product. This note aimed to discuss General Aviation and GARA in depth including the meaning of statue of repose, its exceptions. The various precedents about GARA were also reviewed in here as well. From the GARA, as a comparative legal issue in aviation product liability, there can be some suggestions for revision of Korean Products Liability Act. First, it seems to be reasonable to regulate the specific statute of repose provisions for various category of products. In GARA, the period of 18 years is reasonable concerning to the average aircraft life. Second, in order to avoid exhausting debate and for the judicial economy, it needs to clarify when the statute begins to run. GARA's 18 year limitation period begins to run on the different date whether it was delivered to its first purchaser or a person engaged in the business of selling the aircraft. Last but not least, proper exceptions should be added into the law for equity matter of the statute of repose does not apply. For example, a manufacturer is not protected by GARA if it knowingly misrepresents certain safety information to the FAA.

  • As a way to overcome the problems that when you transmit data to and receive data from End Device to participate in the GRID network, QoS has not been, GARA supports the Diffserv system basically. However, the problem when it is assumed settings related to the Diffserv between the ISP and the ISP is wrong with each other, that it is not possible to receive a complete QoS services began to appear. In this paper, we tried to overcome these drawbacks, in networks based GARA the (Globus Architecture for Reservation and Allocation), using the SLA (Service Level Agrement) server, was treated in the highest priority to the data, the ISP there is provided a method for setting the Diffserv the ISP is even wrong and, using the TOS of the IP header, to solve this, it is described about the direction of future research.

  • Grid computing is an application to obtain the most efficient performance from computing resources in terms of cost and convenience. It is also considered as a good method to solve a problem that cannot be settled by conventional computing technologies such as clustering or is requiring supercomputing capability due to its complex and long-running task. In order to run grid computing effectively, it needs to connect high-performance computing resources in real-time which are distributed geographically. Answering to the needs of this grid application, researchers in several universities with Argonne National Laboratory in the USA (ANL) as the main axis have developed Globus. It is noticed, however, that the quality of service (QoS) is not guaranteed when certain jobs are exchanged through networks in the context of Globus. To tackle with this problem, the ANL has invented Globus Architecture for Reservation and Allocation (GARA). The researchers of this paper constructed a testbed for evaluating the ability to reserve resource in the GARA system and implemented the GARA code for it. We analyzed the applied results and discussed future research plans.

  • Purpose: This study analyzed the influence of restaurant service perception on customer satisfaction and its implications on customers' attitude towards, intention to return to, and word-of-mouth (WOM) regarding a restaurant chain. Research design, data and methodology: Data from 421 respondents were collected using the convenience sampling method. After analyzing the data normality and removing responses with missing data and outliers, 342 responses were selected for further analysis, and the hypotheses were tested using Structural Equation Modeling (SEM). Results: We found that service perception affected customer satisfaction and customer satisfaction affected the customers' attitude toward the restaurant chain, which affected customers' intention to return and WOM about the restaurant chain. Conclusions: This paper provides one of the most important empirical results for managers in the restaurant sector, especially in Indonesia. Restaurant managers should thus provide training to their employees to improve the quality of the interaction with the customers and thereby increase customer satisfaction. The limitations listed in this study include the exclusion of respondents' income. For future research, we suggest investigating models of customer participation or consumer value co-creation for restaurant marketing success. Consumers are generic actors in the service ecosystem engaged in the value co-creation process.

  • The paper presents a model for analysing the shear-lag effect on the slab of twin-girder composite decks subjected to static actions, support settlements and concrete shrinkage, which are the main actions of interest in composite bridge design. The proposed model includes concrete creep behaviour and shear connection flexibility. The shear-lag in the slab is accounted for by means of a new warping function. The considered actions are then applied to a realistic bridge deck and their effects are discussed. The proposed method is utilised to determine the slab effective widths for three different width-length ratios of the deck. Finally, a comparison between the results obtained with the Eurocode EC4-2 and those obtained with the proposed model is performed.

  • This paper proposes a model for the analysis of the construction sequences of steel-concrete composite decks in which the slab is cast-in-situ for segments. The model accounts for early age shrinkage, such as thermal and endogenous shrinkage, drying shrinkage, tensile creep effects and the complex sequences of loading due to pouring of the different slab segments. The evolution of the structure is caught by suitably defining the constitutive relationships of the concrete and the steel reinforcements. The numerical solution is obtained by means of a step-by-step procedure and the finite element method. The proposed model is then applied to a composite deck in order to show its potential.

  • Environmental microorganisms are emerging as an important source of new enzymes for wide-scale industrial application. In this study, novel phytase genes were identified from a soil microbial community. For this, a function-based screening approach was utilized for the identification of phytase activity in a metagenomic library derived from an agricultural soil. Two novel phytases were identified. Interestingly, one of these phytases is an unusual histidine acid phosphatase family phytase, as the conserved motif of the active site of PhyX possesses an additional amino acid residue. The second phytase belongs to a new type, which is encoded by multiple open reading frames (ORFs) and is different to all phytases known to date, which are encoded by a single ORF.

  • Objective: The objective of this study was to estimate genetic parameters of milk, fat, and protein yields within and across lactations in Tunisian Holsteins using a random regression test-day (TD) model. Methods: A random regression multiple trait multiple lactation TD model was used to estimate genetic parameters in the Tunisian dairy cattle population. Data were TD yields of milk, fat, and protein from the first three lactations. Random regressions were modeled with third-order Legendre polynomials for the additive genetic, and permanent environment effects. Heritabilities, and genetic correlations were estimated by Bayesian techniques using the Gibbs sampler. Results: All variance components tended to be high in the beginning and the end of lactations. Additive genetic variances for milk, fat, and protein yields were the lowest and were the least variable compared to permanent variances. Heritability values tended to increase with parity. Estimates of heritabilities for 305-d yield-traits were low to moderate, 0.14 to 0.2, 0.12 to 0.17, and 0.13 to 0.18 for milk, fat, and protein yields, respectively. Within-parity, genetic correlations among traits were up to 0.74. Genetic correlations among lactations for the yield traits were relatively high and ranged from $0.78{\pm}0.01$ to $0.82{\pm}0.03$, between the first and second parities, from $0.73{\pm}0.03$ to $0.8{\pm}0.04$ between the first and third parities, and from $0.82{\pm}0.02$ to $0.84{\pm}0.04$ between the second and third parities. Conclusion: These results are comparable to previously reported estimates on the same population, indicating that the adoption of a random regression TD model as the official genetic evaluation for production traits in Tunisia, as developed by most Interbull countries, is possible in the Tunisian Holsteins.

  • Background: To evaluate serum VEGF-A levels in squamous cell carcinoma of head and neck (SCCHN) patients and relationships with response to therapy. Materials and Methods: Serum VEGF-A levels in patients (n=72) treated with radiotherapy (RT) or radio-chemotherapy (RCT) and controls (n=40) were measured by ELISA. Results: Serum VEGF-A levels of the SCCHN cases were significantly higher (p=0.001) than in healthy controls, and in patients with positive as compared to negative lymph node status (p=0.004). Similarly, patients with advanced stage (Stage III-IV) disease had more greatly elevated levels of serum VEGF-A level than their early stage (Stage I-II) counterparts (p=0.001). In contrast, there was no significant difference (p=0.57) in serum level of VEGF-A in patients with advanced T-stage (T3-4) as compared to early stage (T1-2). Similarly, patients with distant metastasis had no significant (p=0.067) elevation in serum VEGF-A level as compared to non-metastatic disease. However, the non-responder patients had significantly higher serum VEGF-A level as compared to responders (p=0.001). Conclusions: Our results suggest that the serum VEGF-A level may be a useful biomarker for the prediction of response to therapy in SCCHN.
