The identification is the sole carrier of the whole-process information of the pig traceability system. The front identification is the first component, an indispensible part of the proper traceability of the product. This paper conducts in-depth study on company B, company S and company Z from Beijing, Shandong and Zhejiang to understand their specific management process, cooperation model and interest allocation, identification method, willingness to implement, the cost and benefit before and after the implementation as well as the effect of the implementation. The Cannikin Law is also employed to conduct the comparison analysis on the implementation of the system, so as to set an example for the pig traceability system in other relevant companies of the sort. The results show that, the organization model plays the most important part in the front identification management, with “company + bases + farmers” as the most conducive mode for the implementation of front identification yet not prone to be promoted; “company + cooperative + farmers” is more apt to promotion. Other important impact factors of the implementation level of front identification in pig traceability system include the education level of the implementation subject, the scale and the location of the company.

Stability Results

The Peabody Developmental Scales (PDS) and the Movement Assessment of Infants (MAI) were examined for their abilities to detect subtle changes in motor development of infants with Down's syndrome Both assessments were administered to 10 infants before and after a 6-week period A t-test suggested that the MAI was sensitive to developmental changes in the subjects tested from initial test to follow-up. Similar testing using the PDS did not reveal significant differences in the scores, suggesting that the MAI was the more sensitive of the two instruments. When partial correlations were calculated for possible artifactual effects due to age, the MAI still demonstrated greater stability. Results indicate that, for infants with Down's syndrome, the MAI may be preferable to the PDS for detecting changes in motor ability over short periods. However, these results should be considered tentative until a more in-depth study is conducted using a larger number of subjects from a variety of clinical populations.

Computer modeling in acoustics allows for the prediction of acoustical defects and the evaluation of potential remediations. In this article, computer modeling is applied to the case of a barrel-vaulted sanctuary whose architectural design and construction led to severe flutter echoes along the main aisle, which was later mitigated through acoustical remediations. State-of-the-art geometrical acoustics and wave-based simulations are carried out to analyze the acoustics of this space, with a particular focus on the flutter echoes along the main aisle, before and after remediations. Multi-resolution wavelet and spectrogram analyses are carried out to isolate and characterize flutter echoes within measurements and computer-simulated room impulse responses. Comparisons of simulated responses to measurements are also made in terms of decay times and curves. Simulated room impulse responses from both geometrical acoustics and wave-based methods show evidence of flutter echoes matching measurements, to varying degrees. Time-frequency analyses isolating flutter echoes demonstrate better matches to measurements from wave-based simulated responses, at the cost of longer simulation times than geometrical acoustics simulations. This case study highlights the importance of computer modeling of acoustics in early design phases of architectural planning of worship spaces.

Purpose – The purpose of this paper is to examine consumer attitudes toward and willingness to pay (WTP) for traceability of tea in China. Design/methodology/approach – The authors used the payment card method to elicit WTP for certified traceable tea and logistic regression model to analyze the factors that affected consumers’ WTP. Findings – The results revealed that most consumers in China were concerned over tea safety; however, their WTP for certified traceable tea was limited. Only income and the degree of concern over tea safety affected the consumer’s WTP for certified traceable tea greatly. When it came to consumers’ WTP a positive price premium, income level, education, and attitude toward traceability of tea significantly influenced the actual premium consumers were willing to pay. Practical implications – The Chinese government and tea producers should pay attention when implementing tea traceability system. First, raising the consumers’ income contributes to the premiums that consumers are willing to pay for certified traceable tea. Second, social groups, consumer organizations and tea producers should popularize knowledge of tea traceability. Third, given the low price premiums that consumers are willing to pay, the establishment of viable traceability of tea in China requires the producers and the government to bear some of the cost associated with the implementation of this system. Originality/value – In past studies on WTP for certified traceable food, the study is focussed on meat in developed countries, and the research has expanded range of study, by conducting a survey in China to determine consumers’ WTP for certified traceable tea, and by empirically examining the main factors that influence the willingness of consumers to pay a price premium for certified traceable tea, as well as the premium that these consumers are willing to pay.

Split air conditioning (AC) is the most widely used in the community for both commercial and domestic utilities. At the present refrigerant which used in Split AC is mostly common group of HFCs, such as R410a. R410a is a zeotropic refrigerant and if there is a leak in the system, it cannot be added this refrigerant. This will increase the cost of maintenance. The aims of this research is to investigate the retrofit of R410a with R32 on the Split AC system. The R32 is chosen because it has higher latent evaporation heat at the same temperature and has less effect on global warming. The refrigeration effect, the power consumption and the system performance are the main three quantities that want to be examined in this research which are observed before and after retrofit. Experimental investigation conducted during this research, including design and manufacture of experimental equipment, calibration and tools installment, collecting the experimental data and analysis by quantitative description method before and after retrofit. The results informed that cooling effect increased during the research, but the COP system has a slight decrease about 4%. R32 refrigerant is quite feasible as a retrofit refrigerant to R410a refrigerant.

Abstract Alginates are quite abundant in nature as they occur both as a structural component in marine brown algae (Phaeophyceae) comprising up to 40% of dry matter and as capsular polysaccharides in soil bacteria. Alginic acid is the only polysaccharide, which naturally contains carboxyl groups in each constituent residue, and possesses various abilities for functional materials. Experiments were carried out for the water of turbidity 300 NTU. Alginate as such doesn't act as a coagulant instead it should be converted to calcium alginate by adding calcium ions. Calcium chloride was used for imparting calcium ions necessary for the reaction. The dosage of calcium was fixed as 50 mg/L, 75 mg/L, 100 mg/L, 150 mg/L, 200 mg/L, and alginate doses between 2 to 10 mg/L. Calcium dosage below 50 mg/L was not sufficient enough for the formation of egg-box structure which is responsible for the coagulation and flocculation process. For the mechanism of charge neutralization to take place effectively, calcium should be added first followed by alginate. pH and conductivity of the sample remain constant before and after the treatment. The dosage of alginate required for the treatment is less so the cost of treatment also will be very less, thus alginate can replace the usage of chemical coagulants like alum.

Regulating and supervising the energy vehicle (EV) power battery recycling market, improving the utilization rate of EV power battery recycling, and guaranteeing the safety and control of all aspects of recycling treatment require the establishment of an effective traceability system. The decentralization and tamper-proof characteristics of the blockchain can ensure the safety and reliability of relevant data while realizing traceability management. This study establishes the Stackelberg game model to compare and analyze the effects of different government mechanisms on the profits of each subject before and after participating in power battery traceability management. The study further uses the model to explore strategies to improve the enthusiasm of EV power battery recycling subjects to participate in traceability management. The results show that (1) the participation of each recycling subject in EV power battery blockchain traceability can help move more spent power batteries into formal recycling channels; (2) the government should adopt appropriate mechanisms to promote its participation in EV power battery blockchain traceability, the best result being when the government adopts a subsidy mechanism for consumers; and (3) the profit of the EV power battery manufacturer is inversely proportional to the target recycling rate set by the government. Furthermore, the pursuit of a very high target recycling rate is not conducive to the normal implementation of initial EV power battery blockchain traceability management. Therefore, it is crucial for the government to set a reasonable target recycling rate.

ABSTRAK Cody App Academy adalah sebuah tempat kursus berbasis teknologi di Bintaro, Jakarta Selatan. Berdasarkan observasi yang dilakukan penulis, Cody masih menerapkan cara manual untuk menyalakan dan mematikan listrik. Selain itu, hasil dari wawancara oleh pengelola Cody, dapat disimpulkan bahwa hal ini berdampak terhadap efisiensi penggunaan arus listrik yang ada di Cody, yang berkaitan langsung dengan besar atau kecilnya tagihan listrik yang harus dibayarkan oleh pengelola Cody. Maka penulis mengusulkan sebuah solusi berupa prototipe Sistem Pengendali Ruangan dengan teknologi motion berbasis mobile web yang merupakan aplikasi yang dapat merubah sistem manual menjadi sebuah sistem home automation. Aplikasi ini akan secara otomatis mematikan arus listrik ketika ruangan sedang kosong, dilihat dari tidak terdeteksinya gerakan dalam rentang waktu lebih dari 10 menit. Metode pengumpulan data yang yang penulis gunakan adalah pengumpulan data primer dan sekunder yang terdiri dari observasi, wawancara dan studi literatur sejenis. Sedangkan untuk metode pengembangan aplikasi adalah prototipe evolusioner dengan 4 tahap yang mencakup analisis kebutuhan pengguna, membuat satu prototipe. Hasil dari penelitian ini adalah  penerapan home automation yang berupa Sistem Pengendali Ruangan dengan teknologi motion  selama jangka waktu 2 bulan berbasis mobile web terbukti membuat penggunaan listrik di Cody lebih efisien berdasarkan perbandingan tagihan listrik sebelum dan sesudah menggunakan sistem yang penulis usulkan. Hal ini dapat terlihat dari perubahan signifikan pada biaya listrik yang harus dibayarkan Cody per bulan yakni sejumlah 20% lebih efisien dibandingkan tanpa menggunkan sistem yang penulis usulkan.   ABSTRACT Cody App Academy is a technology-based course place in Bintaro, South Jakarta. Based on observations made by the author, Cody is still applying the manual way to turn on and turn off the electricity. In addition, the results of interviews by Cody's managers, it can be concluded that this impacts on the efficiency of the use of electric current in Cody, which is directly related to the large or small bill of electricity that must be paid by the manager of Cody. So the author proposed a solution in the form of prototype Space Control System with motion technology based mobile web which is an application that can change the manual system into a home automation system. This application will automatically turn off the power when the room is empty, judging from the detection of movement in the span of more than 10 minutes. Data collection methods that the author uses is the collection of primary and secondary data consisting of observations, interviews and studies of similar literature. The method of application development is an evolutionary prototype with 4 stages that includes user needs analysis, making a prototype. The result of this research is the implementation of home automation in the form of Room Control System with motion technology for 2 months based on mobile web proved to cause the use of electricity in Cody more efficient based on the ratio of electric bill before and after using the system that the author proposed. This can be seen from the significant change in the cost of electricity that Cody has to pay per month which is 20% more efficient than without using the proposed system. How To Cite : Bahari, A.M.

Electronic commerce, marketing on line, and network economy are today’s keywords of (possible) success. But how many managers effectively know about the cost and benefits of starting to sell their products and services through the Web? How much they should invest at the beginning and how long does it takes to have a break-even point of their investment? In order to give support for better understanding the process of the Web marketing and to have more elements to decide to “dive” or not in this virtual world a System Dynamics (SD) model (Forrester J.W. 1961, 1971, 1980), has been developed. The model has the aim to support strategic decisions for SME involvement in e-Commerce, pointed out to guarantee sustainable growth and medium-long term success. The project e-Impresa1 analyses the whole process of the investment in building and maintaining a web site, taking into account the main variables of E-commerce. Through a case study, a SD business game model has been developed. The model gives the opportunity to users to evaluate different what-if analysis through the simulation period time (2 years) at each model step time (4 weeks). This chapter will explain the overall architecture of the model and will present some results of use of the model in different conditions.

We introduce a method for estimating the cost of adjusting earnings, as well as the earnings elasticity with respect to the net-of-tax share. Our method uses information on bunching in the earnings distribution at convex budget set kinks before and after policy-induced changes in the magnitude of the kinks: the larger is the adjustment cost, the smaller is the absolute change in bunching from before to after the policy change. In the context of the Social Security Earnings Test, our results demonstrate that the short-run impact of changes in the effective marginal tax rate can be substantially attenuated.
