Complex Dynamical Behaviors in a Bertrand Game with Service Factor and Differentiated Products

In this paper, taking the factor of service level provided by the manufacturers into consideration, a static duopolistic Bertrand game with service factor is studied first, in which these two oligarchs produce differentiated products. A dynamic game model of duopoly Bertrand with boundedly rational is established with using the gradient mechanism. By using numerical simulation tools, there are two paths for the system to drop into chaos, that is, flip bifurcation and Neimark-Sacker bifurcation. The symmetric structures can be found from two-parameter bifurcation diagrams. Saddle-homoclinic bifurcation also can be observed from the evolution process of phase portraits. In addition, the emergence of intermittent chaos implies that the established system has the capability of self-regulating, where PM-I intermittency, PM-III intermittency and crisis-induced intermittency have been studied. With the help of the critical curves, the qualitative changes on the basin of attraction are investigated. At last, it can be found that the values of product differentiation degree and service spillover effect are not the bigger the better. Keeping these two parameters in a relatively small range will be conducive to the long-term stable operation of the two manufacturers.

Improving Health Services Affecting Coping Mechanism of the Family of Skizofrenia Patients

Aim: This study aims to determine the effect of health services on coping mechanisms of families with schizophrenia. Methode: The sample consisted of 260 family carers of individuals with schizophrenia in Ponorogo, East Java, Indonesia. Caregivers of families completed filling in the service factor questionnaire and coping mechanism questionnaire. Results: Community Value for Service Factor 0.662 and Family Coping 0.670 which means valid and strong. Community Value for Service Factor 0.853 and Family Coping 0.800 means Reliability. T-Statistics value of 0.205, which means there is an influence between service factors on family coping. Conclusiaon: Research on improving health services for coping mechanisms in family members of individuals with schizophrenia will help design interventions to improve coping mechanisms.

Comparing Contact Stress Estimates of Some Straight Bevel Gears With ISO 10300 Standards

The pitting resistance of straight bevel gears, like other gears, is commonly assessed on the basis of the contact stress in a gear mesh. A new contact stress model for straight bevel gears is used to estimate the contact stress in some gearset designs and compared with predictions from ISO 10300 bevel gear standards. In the cases considered, the new model contact stresses defer from the ISO values in the range of 13% to 33%, with the ISO predictions generally on the higher side. These deviations appear to be somewhat high but not unreasonable because of obvious differences in the two models. The ISO standard uses the mid facewidth cone radius in its contact stress model while the new model uses the cone backend radius which is larger than the mid facewidth cone radius. Another contributing factor is that the load service factor values evaluated from ISO methods are generally higher than those of the new model values, based largely on American Gear Manufacturers Association (AGMA) methods. It should be noted that the power ratings for all the design cases studied are below 10 kW.

E-Government Evaluation on Electronic Procurement Service (LPSE) User Perspective

One of the applications of E gov in Indonesia is to increase transparency in auction of government goods and services procurement is by Electronic Procurement Service (LPSE). LPSE Semarang City has been established since 2010 during the period of 5 (five) years of implementation of LPSE still many weaknesses that must be improved in order to improve the service quality and achievement of objectives of LPSE. In order to improve the service of LPSE, it is expected to be evaluated E Government Evaluation on Electronic Procurement Service (Lpse) User Prespective (Case Study of Lpse Kota Semarang). In general, the implementation of LPSE in Semarang City has been implemented in accordance with the applicable regulations, the factors of this research are Performance, Accessibility, Savings, Transparency, Trust, Presentation and Benefit. The results showed that LPSE service factor in user perspective that need to be improved is accessibility, transparency and trust. While other factors are good enough to support the service, these factors are Performance, Savings and Presentations ease and Benefits.

FAKTOR-FAKTOR YANG MEMENGARUHI KEPUASAN PENGGUNA BPJS

ABSTRAKKepuasan terhadap pelayanan kesehatan dipengaruhi oleh beberapa faktor seperti fasilitas fisik dan lingkungan pelayanan kesehatan, sistem perjanjian termasuk waktu tunggu, menunggu giliran, serta lingkup dan sifat keuntungan layanan kesehatan yang diberikan. Fenomena saat ini masih masyarakat pengguna BPJS yang mengeluhkan pelayanan yang kurang baik, lambatnya penanganan, kerumitan prosedur untuk mendapatkan pelayanan. Tujuan penelitian ini untuk mengidentifikasi faktor- faktor yang memengaruhi kepuasan pengguna BPJS. Desain penelitian yang digunakan adalah diskriptif dengan populasi seluruh pengguna BPJS di RW V sebanyak 91dan jumlah sampel 74 responden pengguna BPJS di RW 05 Kelurahan Sawunggaling Kecamatan Wonokromo Surabaya. Teknik sampling menggunakan Simple Random Sampling. Variabel dalam penelitian ini adalah Faktor-faktor yang memengaruhi kepuasan Pengguna BPJS yang meliputi Kualitas Produk, Harga, Kinerja, Estetika Fasilitas dan komunikasi yang dianalisa secara diskriptif. Hasil penelitian didapatkan mayoritas (97,3 %) responden menyatakan faktor pelayanan merupakan faktor yang paling memengaruhi kepuasan pengguna BPJS. Peningkatan layanan pengurusan administratif dengan pengurusan secara online, perbaikan data base serta kemudahan persayaratan dalam mengurus kepesertaan BPJS agar semakin meningkatkan kepuasan anggota BPJS. Kata-kata kunci: kepuasan, pelayanan, BPJS. ABSTRACT Satisfaction to health services is influenced by several factors such as the physical facility and healthcare environments, system agreements including waiting time, waiting, as well as the scope and nature of the health services provided advantages. The phenomenon in the community of users still complain BPJS poor service, slow handling, the complexity of procedures to obtain services. The purpose of this study to identify factors that affect user satisfaction BPJS.The study used discriptive desing with a sample of 74 respondents BPJS users in RW 05 Sawunggaling Wonokromo Surabaya with Simple Random Sampling. The variables in this study are the factors that affect user satisfaction BPJS.The result of this study showed the majority (97.3%) of respondents said the service factor is the factor most affecting user satisfaction BPJS. Important if BPJS improve management of administrative arrangements to be online, improve the data base as well as convenience to the terms in the care of membership BPJS order to increase level satisfaction. Keywords: Satisfaction, services, BPJS.
