A Novel Hybrid Framework for Co-Optimization of Power and Natural Gas Networks Integrated With Emerging Technologies

In a power system with high penetration of renewable power sources, gas-fired units can be considered as a back-up option to improve the balance between generation and consumption in short-term scheduling. Therefore, closer coordination between power and natural gas systems is anticipated. This article presents a novel hybrid information gap decision theory (IGDT)-stochastic cooptimization problem for integrating electricity and natural gas networks to minimize total operation cost with the penetration of wind energy. The proposed model considers not only the uncertainties regarding electrical load demand and wind power output, but also the uncertainties of gas load demands for the residential consumers. The uncertainties of electric load and wind power are handled through a scenario-based approach, and residential gas load uncertainty is handled via IGDT approach with no need for the probability density function. The introduced hybrid model enables the system operator to consider the advantages of both approaches simultaneously. The impact of gas load uncertainty associated with the residential consumers is more significant on the power dispatch of gas-fired plants and power system operation cost since residential gas load demands are prior than gas load demands of gas-fired units. The proposed framework is a bilevel problem that can be reduced to a one-level problem. Also, it can be solved by the implementation of a simple concept without the need for Karush–Kuhn–Tucker conditions. Moreover, emerging flexible energy sources such as the power to gas technology and demand response program are considered in the proposed model for increasing the wind power dispatch, decreasing the total operation cost of the integrated network as well as reducing the effect of system uncertainties on the total operating cost. Numerical results indicate the applicability and effectiveness of the proposed model under different working conditions

Pengaruh Kombinasi Relaksasi Benson Dengan Murrotal Al- Quran Terhadap Tingkat Cemas & Stress Pada Klien Hemodialisis Di RS Islam Jemursari

Cemas dan stress pada orang hemodialisa disebabkan oleh peningkatan hormon kortisol karena adanya kejenuhan dalam terapi yang dijalani secara terus menerus. Relaksasi benson dan murrotal Al-Quran dapat menurunkan tingkat cemas dan stress dengan menimbulkan respon rileks. Tujuan penelitian ini untuk mengetahui pengaruh relaksasi benson dan murrotal Al- Quran tehadap cemas dan stress. Desain penelitian ini adalah Quasy-Experiment dengan pendekatan pre post test control group design. Sampel berjumlah 36 yang terdiri dari 12 kelompok relaksasi benson, 12 kelompok relaksasi benson dan murrotal Al-Quran, 12 kelompok kontrol. Data diuji dengan t test dan manova. Hasil penelitian menunjukan terdapat perbedaan yang signifikan antara cemas dan stress sebelum dan sesudah intervensi pada masing-masing kelompok (ρ=0,00).

The Influence Of Play Therapy In Developing The Intelligence Of School Age Children With Mental Retardation

Mental Retardation (MR) is a heterogeneous disorder that consists of lower than average intellectual function along with the disruption of adaptive skills. Play therapy is an effective approach to train children with mild MR in studying the concept of learning. Play therapy is conducted in a special room designed as a playground, equipped with special toys to stimulate potential development of children with mild MR. This research aimed to improve the success of the potential development of intelligence in children with mild MR using WISC instrument through play therapy. The study design used quasi-experimental method (quasi-experiment) and qualitative analysis. The subjects of this study were thirteen 7–12 years old children with mild MR in extraordinary school Putra Bangsa Surabaya. The analysis approach used was statistical analysis with Wilcoxon and Kruskal Wallis approaches. A descriptive analysis was subsequently carried out to provide a snapshot of MR conditions that accompany the child including: internal factors, i.e. the phase experienced by the child during pregnancy, childbirth, breastfeeding and the stage of growth and development, and external factors i.e. the family's socioeconomic condition and children upbringing. The results showed that 7 out of 13 children with mild MR had experienced an increase in the potential development of intelligence. In terms of the relation between the therapy frequency and the children success rate, 5 of 7 mild MR children who were successful were in the category of frequent treatment of play therapy. In conclusion, play therapy can increase the potential for successful intelligence development of children with mild MR. This success is associated with treatment frequency and is supported by the presence of concomitant conditions (internal and external factors) in children
